Its main beam is the main load-bearing part of the crane, usually made of steel structure, with sufficient strength and stiffness to bear the weight of the lifted object. Since the hoisting mechanism of the gantry crane is movably installed on the gantry and is extremely vulnerable to the influence of strong winds at high altitudes and may move, the hoisting mechanism requires an anchoring mechanism to fix it. However, the anchoring mechanism used in the existing hoisting mechanism is a plug-in type anchoring structure, which bears a large load, is extremely prone to breakage, has a low service life, and the existing anchoring mechanism has no buffer margin.

[0006] When anchoring, the two anchoring mechanisms clamp the slide rail. By the two anchoring mechanisms that can move away from or approach each other, a clamping type fixing method is realized, so that the hoisting mechanism is anchored, which is fast and convenient.

[0007] In order to solve the problem of how to arrange the moving drive member, it further includes that the moving drive assembly includes a motor and rollers matching the slide rail. The rollers are in rolling contact with the slide rail. The motor is fixedly connected to the hoisting mechanism, and the output end of the motor is in transmission connection with the rollers.

[0008] To solve the problem that the anchoring mechanism cannot achieve self-locking and has no buffer margin, it further includes that the anchoring mechanism includes an anchoring seat and two locking wheels. A receiving groove is formed on one side of the anchoring seat close to the slide rail. Two moving grooves are oppositely formed on the receiving groove, and the moving grooves communicate with the receiving groove.

[0013] It further includes that the connecting mechanism includes a guide rail. A chute matching the guide rail is formed on the anchoring seat, and the guide rail is slidably arranged in the chute.

[0014] To solve the problem that the anchoring mechanism may fall off, it further includes that a limiting block is arranged at the end of the guide rail.

[0015] The beneficial effect of the present utility model is that: an anchoring device for a gantry crane provided by the present utility model realizes a clamping type of fixing through two anchoring mechanisms that can move away from or close to each other, enabling the hoisting mechanism to complete anchoring, which is fast and convenient;

[0027] As Figure 2As shown in the figure, the anchoring device is installed on the hoisting mechanism 2. The anchoring device includes an anchoring driving member 4 and two anchoring mechanisms 5. A slide rail 32 is arranged between the two anchoring mechanisms 5. The output end of the anchoring driving member 4 is in transmission connection with the anchoring mechanism 5. The anchoring driving member 4 is used to provide power for the two anchoring mechanisms 5 to approach or move away from each other. By the two anchoring mechanisms 5 that can move away from or approach each other, a clamping fixation method is realized, so that the hoisting mechanism completes anchoring, which is quick and convenient.

[0028] When anchoring, the two anchoring mechanisms 5 clamp the slide rail 32.

[0029] As Figure 3 , Figure 4 shown in the figure, the anchoring mechanism 5 includes an anchoring seat 51 and two locking wheels 52. An accommodating groove 511 is formed on one side of the anchoring seat 51 close to the slide rail 32. Two moving grooves 512 are oppositely formed on the accommodating groove 511. The moving grooves 512 are communicated with the accommodating groove 511. The moving grooves 512 gradually approach the slide rail 32 from the middle of the accommodating groove 511 to the side end. The locking wheels 52 correspond to the moving grooves 512 one by one.
