Detailed implementation manners

[0020] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] As Figure 1 is a schematic structural diagram of the present utility model. An anchoring device for a crane, the crane includes a frame 1 and a running device 2 installed on the bottom surface of the frame 1. The running device 2 is used to provide power for the movement of the frame 1. The anchoring device 3 is installed on the running device 2. The running device 2 includes a mounting bracket 21 and rollers 22. The mounting bracket 21 is fixedly connected to the frame 1, and the rollers 22 are rotatably connected to the mounting bracket 21. The rollers 22 are used to contact the ground. A plurality of through holes 221 are formed in the rollers 22. In this application, there are four through holes 221. The included angle between the two end portions on both sides of each through hole 221 is 60°. The through holes 221 extend along the circumferential direction of the rollers 22, and the through holes 221 are spaced apart along the circumferential direction of the rollers 22. The through holes 221 are used for the anchoring end of the anchoring device 3 to pass through. The through holes 221 are waist-shaped holes. The displacement amount of the gap for the anchoring rod 33 to freely move relative to the crane body is small, and the overall still remains in the anchored state;

[0022] As Figure 2 、 Figure 3 shown, the running device 2 includes a running driving member 23. The running driving member 23 is fixedly connected to the mounting bracket 21. The output end of the running driving member 23 is in transmission connection with the rollers 22. The running driving member 23 is a motor. The running driving member 23 and the rollers 22 are in transmission connection through a gear set.

[0023] As Figure 2 、 Figure 3 、 Figure 4As shown in the figure, the anchoring device 3 includes a driving assembly 31, an anchoring seat 32 and two anchoring rods 33. The driving assembly 31 is fixedly connected to the mounting bracket 21. The output end of the driving assembly 31 is in transmission connection with the anchoring seat 32. The driving assembly 31 is used to provide power for the anchoring rod 33 to pass through or move away from the through hole 221 on the roller 22. The anchoring rod 33 is elastically connected to the anchoring seat 32. The anchoring rod 33 is located on the circumference where the through hole 221 is located. Through the design of the anchoring rod 33 that moves axially along the roller 22, the anchoring rod 33 enters the through hole 221 of the roller 22, realizing the anchoring of the roller 22, thereby restricting the free movement of the crane and achieving anchoring at any position with a high degree of freedom.

[0024] The driving assembly 31 includes an anchoring driving member 311, a lead screw 312 and a moving seat 313. The anchoring driving member 311 is a motor. The anchoring driving member 311 is fixedly connected to the mounting bracket 21. The output end of the anchoring driving member 311 is in transmission connection with the input end of the lead screw 312. The moving seat 313 is threadedly connected to the lead screw 312. The moving seat 313 is fixedly connected to the anchoring seat 32.

[0025] The driving assembly 31 includes a stabilizing plate 314. The stabilizing plate 314 is fixedly connected to the mounting bracket 21. The output end of the lead screw 312 is rotatably connected to the stabilizing plate 314, increasing the stability of the lead screw 312 and enabling the moving seat 313 to move stably.

[0026] A receiving groove 321 is formed on the anchoring seat 32. An elastic element 34 is arranged in the receiving groove 321. The anchoring rod 33 is slidably arranged in the receiving groove 321. One end of the elastic element 34 abuts against the anchoring rod 33, and the other end abuts against the receiving groove 321. When one of the anchoring rods 33 is blocked by the roller, the anchoring rod 33 can retract into the receiving groove 321 to play an avoidance role.

[0027] A limiting block 331 is arranged on the anchoring rod 33. The limiting block 331 is located in the receiving groove 321. The size of the notch of the receiving groove 321 is smaller than the size of the limiting block 331. The limiting rod 331 can prevent the anchoring rod 33 from detaching from the anchoring seat 32 and increase the connection stability.

[0028] As Figure 5 shown, the included angle between the two anchoring rods 33 is smaller than the included angle between the two ends of the through hole 221, and the included angle between the two anchoring rods 33 is larger than the included angle between the adjacent ends of the two through holes 221. The included angle between the two anchoring rods 33 is between 30° and 60°. Preferably, the included angle between the two anchoring rods 33 is 45°, so as to prevent both anchoring rods 33 from being blocked by the roller 22 body and unable to enter the through hole 221, ensuring that at least one anchoring rod 33 enters the through hole 221.

[0029] After the crane stops, the driving assembly 31 is activated to move the anchoring rod 33 closer to the roller 33 until at least one 33 enters the through hole 221 to complete the anchoring.

[0030] Inspired by the above ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
