Detailed Description

In order that the above objects, features and advantages of the present invention may be more clearly understood, a solution of the present invention will be further described below. It should be noted that the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those described herein; it is to be understood that the embodiments described in this specification are only some embodiments of the invention, and not all embodiments.

As shown in fig. 1 and 2, the present invention provides a moving device (hereinafter, referred to as a moving device) of a cable crane, which includes a beam body 1, a power device, a plurality of movable connecting devices 25, and a plurality of traveling devices. The movable connecting device 25 is arranged on the beam body 1, and the movable connecting device 25 is used for movably connecting with the cable 23. The walking device is arranged on the beam body 1 and is used for moving on the cable 23; the walking device is arranged into a telescopic structure so as to adjust the distance between the beam body 1 and the cable 23; the power device is connected with the beam body 1 and is used for driving the beam body 1 to move along the extending direction of the cable 23.

The power device can provide power for the beam body 1, so that the beam body 1 can move along the cable 23 through the walking device. When the walking devices and the movable connecting devices 25 cross the locking clamps 24, all the walking devices extend towards the cables 23, so that the movable connecting devices 25 are lifted with the beam body 1, the first walking device is contracted towards the beam body 1 (in the advancing direction of the beam body 1) to enable the first walking device to be positioned above the locking clamps 24 and to cross the locking clamps 24, the power device drives the beam body 1 to move to enable the first walking device to cross the locking clamps 24, and then the first walking device moves towards the cables 23 until the first walking device is in contact with the cables 23. The following walkers may then follow this process in sequence across the latching clips 24. When all the walking devices and the movable connecting devices 25 cross the locking clamps 24, the power device can continuously drive the beam body 1 to move to the target position. When the girder 1 is moved to the target position, all the traveling devices are retracted so that the movable coupling devices 25 are lowered along with the girder 1, and then the movable coupling devices 25 are fixedly coupled to the cable 23 so that the girder 1 is fixed to the cable 23. Therefore, the beam body 1 and the movable connecting device 25 can easily stride over the locking clamp 24 through the matching of the walking device and the power device, and the working efficiency of the mobile device is improved.

In the present invention, a plurality means two or more. The beam body 1, the power device, the movable connecting device 25 and the walking device can be common devices in the field, and the invention is not limited.

Further, running gear includes pneumatic cylinder 2 and walking wheel 3, and the cylinder of pneumatic cylinder 2 is connected with roof beam body 1, and walking wheel 3 is connected with the flexible end of pneumatic cylinder 2, and walking wheel 3 is used for removing on cable 23.

The hydraulic cylinder 2 includes a cylinder body and a telescopic rod 22, and the telescopic rod 22 is extendable from or retractable into the cylinder body. The free end of the telescopic rod 22 (i.e. the end of the telescopic rod remote from the cylinder) is a telescopic end. Preferably, the hydraulic cylinder 2 is inserted into the beam body 1. The walking wheel 3 comprises a walking wheel carrier and a walking wheel body, and the walking wheel body is connected with the walking wheel carrier shaft. The telescopic end of the hydraulic cylinder 2 is connected with a walking wheel frame. The hydraulic cylinder 2 and the road wheels 3 are devices which are common in the field, and the invention does not further describe the above.

In this embodiment, when the telescopic end of the hydraulic cylinder 2 is extended, the traveling wheel 3 is pressed down by the hydraulic cylinder 2, but the traveling wheel 3 is obstructed by the cable 23, the telescopic end of the hydraulic cylinder 2 cannot be extended downward, and the cylinder body of the hydraulic cylinder 2 is raised, so that the beam body 1 connected to the cylinder body is raised, and the distance between the beam body 1 and the cable 23 is increased. At the same time, the height of the movable connecting means 25 rises with the beam body 1 so that a space can be created between the movable connecting means 25 and the latching clip 24. Then the telescopic end of the first hydraulic cylinder 2 (i.e. the hydraulic cylinder 2 closest to the latching clamp 24) is retracted and the road wheel 3 on the first hydraulic cylinder 2 is moved towards the beam 1 until the road wheel 3 is above the latching clamp 24 and can pass over the latching clamp 24. Then the power device drives the beam body 1 to move, after the road wheels 3 on the first hydraulic cylinder 2 cross the locking clamp 24, the power device stops driving, the telescopic end of the first hydraulic cylinder 2 extends, and the road wheels 3 on the first hydraulic cylinder 2 are enabled to abut against the cable 23 again. The travelling wheel 3 on the second hydraulic cylinder 2 then moves towards the beam body 1 until the travelling wheel 3 is higher than the locking clamp 24 and can cross the locking clamp 24, and the power device drives the beam body 1 to move. The remaining hydraulic cylinders 2 perform the above-described actions in sequence. When all the travelling wheels 3 and all the movable connecting devices 25 cross the locking clamps 24, the telescopic ends of all the hydraulic cylinders 2 retract, the cylinder bodies of the hydraulic cylinders 2 descend, the beam body 1 descends along with the cylinder bodies, and the distance between the beam body 1 and the cable 23 is reduced. At the same time, the height of the articulated attachment 25 is lowered with the beam 1, and the articulated attachment 25 can be reattached to the cable 23.

Further, the outer edge of the road wheel 3 is set to be a curved surface shape which can be attached to the cable 23.

Specifically, the outer edge of the traveling wheel 3 is curved, so that the outer edge of the traveling wheel 3 can be attached to the surface of the cable 23. Can increase walking wheel 3 and cable 23's area of contact on the one hand, on the other hand can also promote the stability of walking wheel 3 when removing for walking wheel 3 is safer when removing.

Further, the movable connecting means 25 is provided to be movable along the beam body 1.

The position of the movable connecting device 25 on the beam body 1 can be adjusted according to different working conditions. For example, when the power unit stops driving the beam body 1 to move, or at the target position of the beam body 1, the movable connecting means 25 may just correspond to the mounting position of the latching clip 24. The articulating mechanism 25 can only be attached to the latching clip 24 at this time, which can make it difficult to securely fasten the beam 1 to the cable 23. The articulating mechanism 25 can be moved a distance along the beam 1 such that the articulating mechanism 25 can clear the position of the latching clip 24 and couple with the cable 23 to help secure the beam 1 to the cable 23. Of course, if the articulating mechanism 25 does not require adjustment of position, the articulating mechanism 25 may still remain in place.

One side of the clamping block 6 facing the beam body 4 is provided with a sliding groove 7, and two sides of the beam bottom plate 5 are correspondingly inserted into the two sliding grooves 7 respectively. And a limiting bolt 8 which can be used for limiting the movable connecting device 25 to move along the beam body 1 is arranged in the clamping block 6.

Both sides of the girder bottom plate 5 are protruded from the girder body 4, that is, the width of the girder bottom plate 5 is greater than that of the girder body 4, so that the lower portion of the girder body 1 has a substantially inverted T-shaped section. The two sides of the beam bottom plate 5 are respectively inserted into the two clamping blocks 6, so that the beam bottom plate 5 can be used as a sliding rail of the walking device. Be equipped with in the fixture block 6 and communicate the screw hole with spout 7, stop bolt 8 installs in the screw hole, and stop bolt 8's top stretches out (conveniently rotates stop bolt 8) from the screw hole, and stop bolt 8's bottom stretches out and can contact with beam bottom plate 5 from the screw hole. The threaded hole may extend vertically, may extend horizontally, or may extend obliquely, and the present invention is not limited thereto. Of course, a plurality of limit bolts 8 may be disposed in the fixture block 6, and all the limit bolts 8 are preferably distributed at intervals along the length direction of the beam bottom plate 5.

For example, the stopper 10 is a stopper plate provided with a through hole, the stopper plate is mounted on the top side of the backing plate 9 and covers the groove, the diameter of the bottom end of the stopper bolt 8 is larger than that of the through hole, the middle section of the stopper bolt 8 passes through the through hole, and the bottom end of the stopper bolt 8 is restricted in the groove by the stopper plate. And the bottom end of the limit bolt 8 is not fixedly connected with the cushion plate 9, and the cushion plate 9 only moves upwards or downwards and does not rotate circumferentially during the circumferential rotation of loosening or screwing the limit bolt 8.

Of course, the supporting frame 13 may be a component commonly known in the art, and a person skilled in the art may need to select a suitable structure, for example, the supporting frame may be configured in a shape like a Chinese character 'ri', an L shape, an F shape, or the like, and the invention is not limited thereto.

Further, as shown in fig. 1, the power device comprises a winch 17 and a fixed pulley 18, the fixed pulley 18 is used for being mounted on a cable 23, the winch 17 is mounted on the beam body 1, and a steel wire rope 19 of the winch 17 passes around the fixed pulley 18 and is connected with the beam body 1; when the winch 17 winds the wire rope 19, the wire rope 19 pulls the beam body 1 to move toward the fixed sheave 18.

The winch 17 may be installed at a side or a top of the girder 1, etc., and the present invention is not limited thereto. Preferably, the winch 17 is provided on the top side of the girder 1. The fixed pulley 18 may be the above, and the present invention is not limited thereto. Those skilled in the art will appreciate that the crown block 18 includes a block wheel carrier mounted on a cable 23, such as may be secured to the cable 23 by mechanical claws, clips or wire, and a block wheel body that is in turn connected to a block wheel carrier shaft.

The position of the fixed pulley 18 needs to be higher than that of the beam body 1 so as to conveniently draw the beam body 1. Specifically, a winch 17 is installed on the top side of the girder 1, and a wire rope 19 on the winch 17 is connected to the end of the girder 1 after passing around a pulley body of the fixed pulley 18. The winch 17 may be an electric winch 17 or a hydraulic winch 17, etc., and the present invention is not limited thereto. When the winch 17 winds the wire rope 19, the length of the wire rope 19 extending out of the winch 17 is reduced, and the wire rope 19 pulls the beam body 1 to move toward the fixed sheave 18, that is, the beam body 1 moves upward. When the beam body 1 reaches the target position, i.e., the beam body 1 reaches the position closest to the fixed sheave 18, the fixed sheave 18 can be remounted to a higher position so as to pull the beam body 1 higher. Of course, the winch 17 can also pay out the wire rope 19 step by step to move the beam body 1 away from the fixed sheave 18, i.e. the beam body 1 moves downwards.

In the present embodiment, the wire 19 is a flexible component, and as the distance between the beam 1 and the fixed pulley 18 changes, the posture (for example, the inclination angle or the distance between the wire 19 and the cable 23) of the wire 19 is also dynamically adjusted adaptively, which helps to ensure the stable movement of the beam 1.

In addition, the drive device may also be a type of device. For example, the driving means is an electric telescopic bar, one end of the electric telescopic bar 22 is hinged to the front end of the beam body 1, the other end of the electric telescopic bar 22 is hinged to the cable 23, and when the electric telescopic bar 22 is shortened, the traction beam body 1 is moved forward.

Further, as shown in fig. 3, the movable connection device 25 includes a base 20 and two clamping blocks 21, the base 20 is connected to the beam 1, the clamping blocks 21 are hinged to the base 20, and the base 20 and the two clamping blocks 21 can clamp the cable 23 therebetween. An expansion link is arranged between the clamping block 21 and the base 20, and the expansion link can drive the clamping block 21 to clamp or loosen the cable 23.

When the power device drives the beam body 1 to move, the base 20 and the clamping block 21 can be properly opened, so that excessive friction between the movable connecting device 25 and the cable 23 is avoided. When the beam 1 reaches the target position, the base 20 and the clamp block 21 clamp the cable 23 so that the articulating mechanism 25 is firmly secured to the cable 23. The telescopic rod 22 may be a hydraulic telescopic rod 22, an electric telescopic rod 22 or a manual telescopic rod 22, but the present invention is not limited thereto. The base 20 and the clamp block 21 may be plate members or rod members, and the present invention is not limited thereto. The base 20 and the clamping block 21 are preferably C-shaped or arc-shaped so that the base 20 and the clamping block 21 can be closely fitted on the cable 23.

Further, as shown in fig. 3, an installation hole for the cable 23 to pass through is provided between the base 20 and the two clamping blocks 21, and a hole wall of the installation hole can be attached to the surface of the cable 23. The telescopic rod is positioned outside the mounting hole.

The cable 23 can be inserted into the mounting hole, and the contact area between the cable 23 and the movable connecting device 25 is large, so that the movable connecting device 25 can be firmly fixed on the cable 23. And the telescopic rod 22 is positioned outside the mounting hole, the interference between the telescopic rod 22 and the cable 23 can be avoided.

The operation of the mobile device will be described with reference to fig. 1 and 2.

Step one, the moving means is mounted on the cable 23.

At this point, the blocks 21 are fully open and any one of the blocks 21 is away from the cable 23 to avoid jamming of the articulating mechanism 25 at the locking clip 24. And all running gear is extended to the cable 23, the movable connecting device 25 is far away from the cable 23 along with the beam body 1. The distance between the beam body 1 and the cable 23 is large, and the height of the movable connecting device 25 is higher than that of the locking clamp 24 and can cross the locking clamp 24. The power device drives the beam body 1 to move, and the beam body 1 moves along the cable 23 through the traveling device. Of course, the running gear may be extended again when the displacement device approaches the locking clip 24.

Step two, the movable connecting device 25 spans the locking clamp 24.

When the beam body 1 moves to a position close to the locking clamp 24, the first walking device (in the advancing direction) retracts towards the beam body 1 until the height of the first walking device is higher than that of the locking clamp 24 and can cross the locking clamp 24, and the power device drives the beam body 1 to move until the first walking device crosses the locking clamp 24. The first running gear is then extended towards cable 23 until the first running gear comes into contact with cable 23.

Then the second running gear retracts towards the beam body 1 until the height of the second running gear is higher than that of the locking clamp 24 and can cross the locking clamp 24, and the power device drives the beam body 1 to move until the second running gear crosses the locking clamp 24. The second running gear is then extended towards cable 23 until the second running gear comes into contact with cable 23. The following walking device also repeatedly executes the above process, and details are not repeated. And during the process that each running gear crosses the locking clip 24, the movable connecting device 25 also crosses the locking clip 24.

When the last running gear and the last articulated gear 25 straddle the locking clamp 24, the last running gear is extended towards the cable 23 until it comes into contact with the cable 23. The power unit may then continue to drive the beam 1 towards the target position.

It should be noted that the power unit may be in an operating or stopped state during the extension or retraction of each running gear.

And step three, fixing the movable connecting device 25 with the cable 23.

When the beam 1 is moved to the target position, all the traveling devices are retracted toward the beam 1 so that the interval between the beam 1 and the cable 23 is reduced and the articulated device 25 is close to the cable 23. The movable connecting means 25 is then fixedly connected to the cable 23 so that the girder 1 is firmly mounted on the cable 23. For example, three clamping blocks 21 are clamped around the cable 23.

However, if the latching clip 24 is present at the target location, there is interference between the articulating mechanism 25 and the latching clip 24, requiring adjustment of the position of the articulating mechanism 25. Specifically, after the last walking device and the last movable connecting device 25 cross the locking clamp 24, the position of the movable connecting device 25 is adjusted to move the movable connecting device 25 on the beam body 1 for a certain distance, so that the movable connecting device is staggered with the locking clamp 24, and then the movable connecting device 25 is fixedly connected with the beam body 1 again. All the running gears are then retracted towards the beam 1 and the articulated connection 25 is fixedly connected to the cable 23. At the moment, the cable crane enters a working state and can hoist various devices.
