As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Please refer to fig. 1 and fig. 2, which are schematic perspective views of a trowelling machine according to an embodiment of the present invention. In the present embodiment, the trowel 1 is applied to a self-elevating building platform device, and specifically, the trowel 1 is provided on a telescopic arm 60 of the self-elevating building platform device. The trowelling machine 1 comprises a trowelling device 10 and a leveling device 30 for adjusting the levelness of the trowelling device 10. The leveling device 30 is disposed between the telescopic arm 60 and the leveling device 10, the leveling device 10 contacts with a substrate surface (such as a ground surface, not shown) to be leveled, and the leveling device 30 ensures the levelness of the leveled substrate surface by adjusting the levelness of the leveling device 10, so as to ensure that the leveled substrate surface meets a preset quality requirement.

Referring to fig. 3, in the present embodiment, the trowelling machine 1 further includes a control system 50, the control system includes a sensing device 52 and a control device 54, the sensing device 52 is used for sensing the levelness of the trowelling device 10 and transmitting the sensed levelness to the control device 54, the control device 54 compares the sensed levelness with a preset levelness range, and controls the leveling device 30 according to the comparison result, so that the leveling device 30 correspondingly adjusts the levelness of the trowelling device 30 to the preset levelness range.

Referring to fig. 1, 2, 4 to 6, in the present embodiment, the leveling device 30 is a two-degree-of-freedom leveling device, and can be used to adjust the levelness of the leveling device 10 in the first orientation and the second orientation. The sensing device 52 is a dual-tilt angle sensing device, which is disposed on the floating device 10 and is used for sensing horizontal tilt angles of the floating device 10 in the first direction and the second direction, so as to obtain levelness of the floating device 10 in the first direction and the second direction. In other embodiments, the sensing device may be two or more sensing devices separated from each other, and the two or more sensing devices are disposed at the same position or different positions of the floating device 10, wherein at least one sensing device is used for sensing the levelness of the floating device 10 in the first orientation, and at least another sensing device is used for sensing the levelness of the floating device 10 in the second orientation.

The troweling device 10 comprises a troweling head 12 and a connecting frame 14 for mounting the troweling head 12. The leveling device 10 is arranged above the connecting frame 14, and the levelness of the trowel head 12 in the first direction and the second direction is adjusted by adjusting the levelness of the connecting frame 14 in the first direction and the second direction. In the present embodiment, the connecting frame 14 is further provided with a power device 15 for driving the troweling head 12 to perform troweling work, and a control electrical cabinet 16 for electrically controlling the troweling machine 1. The control device 54 is disposed in the control electrical cabinet 16.

In other embodiments, the control electrical cabinet 16 may further include a communication device (not shown), and the control device 54 communicates with an external control device through the communication device, so that a user can control the trowelling machine 1 through the external control device without touching the trowelling machine 1, for example, stop the operation of the trowelling machine 1, modify a preset levelness, and the like.

The leveling device 30 comprises a first leveling component 32 and a second leveling component 34, wherein the first leveling component 32 is used for adjusting the levelness of the trowel 1 in a first direction, and the second leveling component 34 is used for adjusting the levelness of the trowel 1 in a second direction, the first direction and the second direction are two directions which are not overlapped and not parallel, and specifically, the first direction and the second direction can be vertical or angular. In the present embodiment, the first azimuth is perpendicular to the second azimuth, the first azimuth being the X azimuth shown in the drawing, and the second azimuth being the Y azimuth shown in the drawing. The levelness of the trowelling machine 1 in the first direction is determined by the height of two ends of the trowelling machine 1 distributed along the first direction in the third direction, and when the two ends of the trowelling machine 1 distributed along the first direction are at the same height position in the third direction, the trowelling machine 1 is at the optimal horizontal position in the first direction; the levelness of the trowelling machine 1 in the second direction is determined by the height of two ends of the trowelling machine 1 distributed along the second direction in the third direction, and when the two ends of the trowelling machine 1 distributed along the second direction are at the same height position in the third direction, the trowelling machine 1 is at the optimal horizontal position in the second direction. Wherein the third orientation is perpendicular to both the first orientation and the second orientation. In the present embodiment, the third azimuth is the illustrated Z azimuth.

In this embodiment, the first leveling assembly 32 and the second leveling assembly 34 are stacked in the illustrated Z-orientation. The first leveling assembly 32 is disposed above the second leveling assembly 34, and the second leveling assembly 34 is secured to the first leveling assembly 32. The overlapping arrangement of the first leveling component 32 and the second leveling component 34 along the Z direction can avoid increasing the transverse dimension of the trowel 1, so that the trowel 1 has a compact structure. The first leveling component 32 is mounted on the telescopic arm 60, the second leveling component 34 is mounted on the first leveling component 32 and the leveling device 10, when the levelness of the trowel 1 in the first direction is adjusted, the posture of the first leveling component 32 in the first direction is changed, and therefore the second leveling component 34 is driven to change the posture of the trowel in the first direction, and the second leveling component 34 drives the leveling device 10 to change the posture of the trowel in the first direction. When the levelness of the trowel 1 in the second direction is adjusted, the posture of the second leveling component 34 in the second direction is changed, and therefore the trowelling device 10 is driven to change the posture in the second direction. Thus, levelness adjustment of the troweling apparatus 10 in two orientations is achieved by two leveling assemblies that are stacked one above the other.

In this embodiment, the first leveling component 32 includes a first reference member 321, a first adjusted member 322, and a first adjusting component 323 disposed between the first reference member 321 and the first adjusted member 322, wherein the first reference member 321 is fixed on the telescopic arm 60, the first adjusted member 322 is pivoted to the first reference member 321, and a pivot about which the first adjusted member 322 can rotate is perpendicular to the first orientation and the third orientation. In the present embodiment, the first adjusted component 322 is rotatably connected to the first reference component 321 by a hinge lug. Specifically, in this embodiment, the first adjusted component 322 and the first reference component 321 are rotatably connected by two sets of hinge eyes, the two sets of hinge eyes are symmetrically distributed, two hinge eyes 322a of each set of hinge eyes are connected by a pin 322b, and the pin 322b of the two sets of hinge eyes forms a pivot around which the first adjusted component 322 can rotate.

The first adjusting assembly 323 is disposed between the first reference member 321 and the first adjusted member 322, and includes a first power member 3230 and a first leveling actuator 3231. The first power member 3230 outputs power, and the output power pushes the first leveling actuator 3231 to move. The first leveling actuator 3231 is a ramp slider mechanism, and includes a first ramp 3232 extending along a first direction and a third direction, and a first slider 3233 engaged with the first ramp 3232 and moving along the first ramp 3232. The first inclined rail 3232 is fixed to the first reference member 321, the first slider 3233 is also connected to the first power element 3230 and the first adjusted element 322, and moves along the first inclined rail 3232 under the driving of the first power element 3230, and because the heights of the different positions of the first inclined rail 3232 in the third direction are different, the first slider 3233 pushes and pulls the first adjusted element 322 in the moving process, so as to adjust the height difference of the two ends of the first adjusted element 322 distributed along the first direction in the third direction. Specifically, in the present embodiment, the first slider 3233 includes a body 3234, a first guide portion 3235 and a second guide portion 3236 provided on the body 3234, and an adaptor 3237. The body 3234 is hinged to the adaptor 3237, and the adaptor 3237 is further hinged to the end of the first power member 3230, so that the body 3234 can rotate relative to the first power member 3230 as required during the movement of the first slider 3233 along the first inclined rail 3232, thereby providing flexibility for the first adjustment assembly 323 to perform leveling.

The first guide portion 3235 is engaged with the first inclined rail 3232, in this embodiment, the first inclined rail 3232 is provided with a sliding groove 3238, the sliding groove 3238 extends along the first direction and the third direction at the same time, and the first guide portion 3235 is embedded in the sliding groove 3238 and is driven by the first power element 3230 to move along the sliding groove 3238. The first leveling actuator 3231 further includes a slide rail 3239, the slide rail 3239 is mounted on the first adjusted part 322, and the slide rail 3239 is parallel to a plane of the first adjusted part 322 and extends along a first direction. The second guide portion 3236 is engaged with the slide rail 3239 and can move along the slide rail 3239 under the driving of the first power member 3230. Since the first inclined rail 3232 extends along the first direction and the third direction at the same time, during the process that the first sliding block 3233 moves along the first inclined rail 3232, the height positions of the two ends of the first adjusted part 322 along the first direction in the third direction are adjusted, so as to adjust the levelness of the first adjusted part 322 along the first direction.

It is understood that in other embodiments, the positions of the first inclined rail 3232 and the sliding rail 3239 can be interchanged, i.e., the first inclined rail 3232 can be installed on the first adjusted component 322, and the sliding rail 3239 can be installed on the first reference component 321.

It is understood that in other embodiments, the adapter 3237 can be omitted and the body 3234 can be directly hinged to the end of the first motive member 3230.

It is to be understood that although the above-mentioned embodiment describes that the first inclined rail 3232 is provided with the sliding groove 3238, and the first guide portion 3235 is embedded in the sliding groove 3238 to achieve the engagement therebetween, in other embodiments, the first guide portion 3235 may be a groove portion, and the first inclined rail 3232 is provided with a protrusion portion engaged with the groove portion to achieve the engagement therebetween. Similarly, the engagement between the second guide portion 3236 and the slide rail 3239 can be achieved by providing a groove portion on the second guide portion 3236 and a mating protrusion on the slide rail 3239, or by providing a protrusion on the second guide portion 3236 and a mating groove portion on the slide rail 3239.

It is to be understood that although the first leveling assembly 32 has a separate first reference member 321 in the above-described embodiment, the first reference member 321 is mounted to the telescopic arm 60 to achieve connection with the telescopic arm 60, in other embodiments, the first reference member 321 may be replaced with a structure at the end of the telescopic arm 60 without providing a separate first reference member 321. That is, the first reference member 321 of the first leveling assembly 32 may be constructed using a plate or frame at the end of the telescopic arm 60, and a portion of the first adjusting assembly 323 is structurally mounted to the end of the telescopic arm 60.

In this embodiment, the first power element 3230 is a hydraulic cylinder, the hydraulic cylinder is disposed on the seat body 3240, the seat body 3240 is fixed on the first adjusted element 322, an axis of the hydraulic cylinder is disposed along a first direction, the connecting frame 14 is disposed with the hydraulic power station 18, and the hydraulic power station 18 provides power to the hydraulic cylinder by using a hose (not shown) to extend or retract a piston rod of the hydraulic cylinder along the first direction, so as to drive the first slide block 3233 to move along the first direction. In other embodiments, the housing 3240 for holding the hydraulic cylinder can also be disposed on the first reference member 321.

The second leveling assembly 34 has the same structure and leveling principle as the first leveling assembly 32, and includes a second reference member 341, a second adjusted member 342, and a second adjusting assembly 343 disposed between the second reference member 341 and the second adjusted member 342. The difference is that in this embodiment, the second reference member 341 is the first adjusted member 322, the second adjusted member 342 is fixed on the floating device 10, the second adjusted member 342 is pivoted on the second reference member 341, and a pivot about which the second adjusted member 342 can rotate is perpendicular to the second orientation and the third orientation. The second adjusting assembly 343 includes a second power member 3430 and a second leveling actuator 3431, and the second leveling actuator 3431 includes a second inclined rail 3432 extending along the second direction and the third direction, and a second sliding block 3433 cooperating with the second inclined rail 3432. Since the second inclined rail 3432 extends along the second direction and the third direction, during the process that the second sliding block 3433 moves along the second inclined rail 3432, the height positions of the two ends of the second member 342 along the second direction in the third direction are adjusted, so as to adjust the levelness of the second member 342 along the second direction.

Other structural features of the second leveling assembly 34 that are identical to those of the first leveling assembly 32 are omitted.

It is understood that in other embodiments, the second reference member 341 and the first adjusted member 322 may be two different members, and the second reference member 341 is fixed on the first adjusted member 322.

It is understood that in other embodiments, the upper end of the connecting frame 14 of the troweling apparatus 10 may be used instead of the second adjusted member 342 without providing another second adjusted member 342. That is, the second adjusted member 342 may be formed by a plate or a frame body coupled to the upper end of the connecting frame 14, and a part of the second adjusting assembly 343 is mounted to the upper end of the connecting frame 14.

It is understood that in other embodiments, the first sliding block 3233, the second sliding block 3433, and/or the sliding rail 3239 can be omitted or the similar scheme can be adopted, for example, the end of the first power member 3230 can simultaneously serve as the sliding block matched with the first inclined rail 3232, and the end of the second power member 3430 can simultaneously serve as the sliding block matched with the second inclined rail 3432, in any case, it is only necessary that the first power member 3230 can push the first adjusted member 322 along the first inclined rail 3232, and the second power member 3430 can push the second adjusted member 342 along the second inclined rail 3432.

One embodiment of the trowel 1 for automatically adjusting the levelness of the two orientations of the trowel device 10 is described in detail below. The sensing device 52 senses levelness of the floating device 10 in the first direction and the second direction in real time and transmits the sensed levelness to the control device 54, the control device 54 compares the sensed levelness of the two directions with a preset levelness range respectively, if the sensed levelness of the two directions is within the preset levelness range (or if the preset levelness ranges corresponding to the two directions are different, the sensed levelness of the two directions respectively fall into the corresponding preset levelness ranges), the control device 54 does not output a signal, and the leveling device 30 keeps the current poses of the two directions unchanged. If the sensed levelness of the first orientation exceeds the preset levelness range, the control device 54 activates the hydraulic power station 18 corresponding to the first power member 3230, the hydraulic power station 18 outputs power to the first power member 3230, the first power member 3230 is activated, and the first slider 3233 is driven to move along the first inclined rail 3232, for example, the first slider 3233 is driven to move along the first inclined rail 3232 toward a direction close to the first reference member 321, so that the height difference between the two ends of the first adjusted member 322 along the first orientation is reduced. If the sensed levelness of the second orientation exceeds the preset levelness range, the control device 54 activates the hydraulic power station 19 corresponding to the second power member 3430, the hydraulic power station 19 outputs power to the second power member 3430, the second power member 3430 is activated, and the second sliding block 3433 is driven to move along the second inclined rail 3432, for example, the second sliding block 3433 is driven to move along the second inclined rail 3432 toward the direction close to the second reference member 341, so that the height difference between the two ends of the second adjusted member 342 along the second orientation is reduced. Therefore, the purpose that the levelness of the floating device 10 falls into the preset levelness range is achieved by adjusting the pose of the leveling device 30 in the corresponding direction.

Although the foregoing embodiment is only an example in which levelness of the leveling trowel 1 is achieved in two directions, and the trowel 1 is used for leveling a horizontal surface such as a floor, it should be understood that the trowel 1 according to the embodiment of the present invention may also be used for leveling other non-horizontal surfaces, for example, a wall surface perpendicular to a horizontal surface, or an inclined surface having a certain inclination angle with respect to the horizontal surface, in which case, only the first direction and the second direction are set to be parallel to a surface to be leveled, and the third direction is set to be perpendicular to the leveled, and in this case, the sensing device 52 senses a height difference of the leveling device 10 in the third direction along the first direction and the second direction, and the control device 54 compares a sensing result of the sensing device 52 with a preset height difference, and controls the leveling device 30 according to the comparison result.

In summary, the leveling device and the trowelling machine using the leveling device provided by the embodiments of the present invention are provided with two sets of leveling components, wherein the first leveling component adjusts a height difference of the trowelling machine in a third direction along the first direction, and the second leveling component adjusts a height difference of the trowelling machine in the third direction along the second direction, so that the trowelling machine has two degrees of freedom; the other two groups of leveling assemblies are overlapped along the third direction, so that the transverse size of the trowelling machine is reduced, the structure of the trowelling machine is more compact, the height difference of the adjusted piece relative to the reference piece in the third direction is adjusted by each group of leveling assemblies in a way of an inclined rail sliding block, the whole structure of the leveling device is simple, the accurate control of the levelness of the trowelling machine is easy to realize, and the high cost and the control complexity caused by complicated structures are avoided; and moreover, the hydraulic oil cylinder is used for driving, so that the shaking in the leveling process is reduced.
