Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1 to 5, fig. 1 is a schematic diagram of the tower crane perpendicularity detection device of the present invention in an inclined state. FIG. 5 is a schematic diagram of the tower crane perpendicularity detection device of the invention installed on a tower crane in an inclined state.

With continuing reference to fig. 1-5, the invention provides a tower crane perpendicularity detection device, comprising: a support member 1, a position indicating member 2, a gravity traction ball 3 and an indicating rod assembly 4.

The supporting member 1 and the position indicating member 2 are respectively plate-shaped, that is, the supporting member is a supporting plate, and the position indicating member is a position indicating plate. The support member is disposed in a horizontal direction, that is, the plate surface direction of the support plate is disposed in a horizontal direction. The position indicating piece is parallel to the supporting piece, the position indicating piece and the supporting piece are arranged oppositely, and the position indicating piece is arranged above the supporting piece.

The supporting member 1 is provided with a through hole. The through-holes of the support member are arranged in a vertical direction. A rolling ball 11 is rotatably mounted in the through hole.

The position indicating piece 2 is erected right above the supporting piece 1. The inner side of the index 2 near the support has an origin 20. The origin 20 is arranged right to the center of the rolling ball 11, i.e., a line connecting the origin and the center of the rolling ball is arranged in the vertical direction. The inside of the position indicator 2 is provided with graduation marks 200. The scale lines 200 are a plurality of concentric circles centered on the origin 20.

The gravity traction ball 3 is arranged below the rolling ball 11. The gravity traction ball 3 is connected to the lower portion of the rolling ball 11 through a strut 31.

The indicator rod assembly 4 is a telescopic rod assembly. The indication rod assembly 4 is disposed in a vertical direction. The indicating rod assembly 4 is connected to the upper part of the rolling ball 11 and abuts against the origin 20, and the indicating rod assembly 4 is coaxially arranged with the center of the rolling ball 11, the support rod 31 and the center of the gravity traction ball 3.

The tower crane perpendicularity detection principle of the tower crane perpendicularity detection device is as follows:

after the tower crane is installed, a bearing plate of the tower crane verticality detection device is fixedly installed at the upper end of a tower body 5 of the tower crane, so that the bearing plate is arranged along the horizontal direction, at the moment, the tower body is arranged along the vertical direction, and the bearing plate is perpendicular to the tower body.

After the tower has been tilted, the support 1 is caused to turn over. As shown in fig. 5, the support plate is mounted on the right side of the tower body, and the upper end of the tower body is inclined toward the left side in the drawing, causing the support member to be turned toward the left side. After the supporting plate overturns towards the left side, the rolling ball 11 overturns towards the reverse direction of the overturning direction of the supporting member 1 under the gravity traction of the gravity traction ball 3, namely, the rolling ball overturns towards the right side, so that the indicating rod assembly 4 is always arranged along the vertical direction, and meanwhile, the indicating rod assembly is always arranged along the vertical direction due to the corresponding overturning of the position indicating plate, the gap between the top of the indicating rod assembly and the position indicating plate is formed, and the indicating rod assembly extends to abut against the scale mark 200 after the gap is formed. If the top of the indication rod component is offset from the origin, the tower body can be judged to be inclined.

After the tower body is inclined, the radius a of a concentric circle of the indicating plate to which the indicating rod assembly points, namely the reading of the scale marks on the indicating plate of the indicating rod assembly. At this time, the length of the indication rod assembly (the length of the indication rod assembly after being elongated) is b, and the original length of the indication rod assembly is c (i.e., the distance from the upper portion of the rolling ball to the inner side of the index member). The length of the tower body is L. The actual offset X of the upper end of the tower body can be calculated from the above data, specifically, X ═ a × (L-c) ÷ b.

In addition, the direction of the inclination of the tower body can be judged by the position of the indication rod component abutting against the scale mark. Specifically, the scale marks on the inner side of the position indicating plate are divided into four phenomena which correspond to four directions of the south, the east and the west respectively, four boundary lines of the south, the west, the north and the west can be further divided, and the whole concentric circle is divided into 8 areas to roughly indicate the inclination direction of the tower crane, as shown in fig. 3.

The tower crane perpendicularity detection device is arranged on the tower body of a tower crane, so that the inclination direction of the tower crane can be judged according to the position of the indication rod component abutting against the scale mark, and after the tower crane perpendicularity detection device is arranged on the top of the tower body, the actual offset of the top of the tower crane can be calculated. The device for detecting the perpendicularity of the tower crane provided by the invention is not limited by factors such as fields, personnel and weather on one hand, and does not influence the operation of the tower crane.

In a preferred embodiment, the outer diameter of the rolling ball is greater than the thickness of the support. The upper part of the rolling ball 11 extends to the outside of the upper port of the through hole, and the lower part of the rolling ball 11 extends to the outside of the lower port of the through hole. The upper port and the lower port are respectively provided with an anti-drop flange. The anti-drop flange plates of the upper port of the through hole and the lower port of the through hole are respectively attached to the two opposite sides of the rolling ball 11 to prevent the rolling ball from being separated from the through hole.

In this embodiment, the inner wall of the through hole is arc-shaped, and the radian of the inner wall of the through hole is adapted to the radian of the spherical surface of the rolling ball 11.

In a preferred embodiment, the support member 1 is provided with upright posts 12 at opposite ends thereof. The upright 12 is connected to the inside of the index 2.

In the present embodiment, the support member has a rectangular plate shape. Four corners of the supporting member are respectively connected with an upright post.

In this embodiment, the shape and size of the index member are adapted to the shape and size of the support member. A plurality of concentric circles of scale marks on the inner side of the position indicating piece are arranged at equal intervals. The distance a of the top of the indicating rod assembly deviating from the original point can be observed through the position of the indicating rod assembly abutting against the scale mark on the inner side of the position indicating piece. And scale marks are arranged on the indicating rod assembly to display the length b of the indicating rod assembly.

As a better implementation mode, a camera is installed on the supporting plate, the camera is aligned to the scale marks of the position indicating plate and the scales of the indicating rod assembly, the camera collects the position of the indicating rod assembly, which is abutted against the scale marks of the position indicating plate, and the image of the length of the indicating rod assembly is transmitted to the controller through a wireless signal, and the controller displays the image on a display screen connected to the controller for monitoring personnel to check so as to avoid high-altitude observation.

As a preferred embodiment, the indication rod assembly 4 includes: a sleeve 41, an elastic member, and a core pin 42. Wherein one end of the sleeve 41 is connected to the upper portion of the rolling ball 11. The elastic member is disposed inside the sleeve 41. One end of the core bar 42 is inserted into the other end of the sleeve 41. The resilient member is supported on the core rod 42. The other end of the core rod 42 abuts against the origin 20 of the position indicator 2.

In a preferred embodiment, the elastic member has an elastic force greater than the gravity of the core rod 42 and less than the gravity of the gravity traction ball 3, i.e. when the tower crane is inclined, the gravity of the gravity traction ball should be much greater than the elastic member so as to quickly pull the indication rod assembly to the state of restoring the vertical arrangement, and the elastic member has an elastic force of a magnitude not changing the vertical arrangement of the indication rod assembly,

in this embodiment, the elastic member is a coil spring.
