[0023] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Example

[0025] Please refer to Figures 1 to 4 As shown, this embodiment provides a gantry crane anti-collision device that facilitates the replacement of anti-collision plates, including: a mounting plate 1, which is installed on the inner side of the gantry crane support 2 via a vibration damping mechanism. An anti-collision plate 4 is detachably connected to the side of the mounting plate 1 facing the crane 3 via a limiting mechanism. The anti-collision plate 4 has an integrally formed protrusion 401, and a groove 101 is formed on the mounting plate 1. When the anti-collision plate 4 is in the installed state, the protrusion 401 is engaged inside the groove 101. The vibration damping mechanism installs the mounting plate 1 on the inner side of the gantry crane support 2, effectively buffering the impact force transmitted to the support when the crane 3 strikes the anti-collision plate 4, reducing damage to the support, and extending the service life of the gantry crane. The mounting plate 1 and the anti-collision plate 4 are detachably connected via the limiting mechanism, facilitating replacement when the anti-collision plate 4 is damaged, improving maintenance efficiency. The engaging design of the protrusion 401 and the groove 101 ensures that the anti-collision plate 4 is structurally stable after installation and is not easily dislodged during impact, guaranteeing the protective effect.

[0026] The limiting mechanism includes a limiting spring 501, a pull rod 502, and an arc-shaped limiting plate 503. An installation groove 5 is provided on the inner wall of the groove 101. The limiting spring 501 is fixedly installed inside the installation groove 5. The pull rod 502 movably passes through the inner ring of the limiting spring 501, with one end extending to the outside of the mounting plate 1. The arc-shaped limiting plate 503 is movably installed inside the installation groove 5, with one side abutting against one end of the limiting spring 501. One end of the pull rod 502 is fixedly connected to the arc-shaped limiting plate 503 abutting against one side of the limiting spring 501. An external slot 402 is provided on the protruding plate 401. When the protruding plate 401 is fully engaged in the groove 101... When the anti-collision plate 4 is inside the 01, the arc-shaped limiting plate 503 is inserted into the outer slot 402. The limiting mechanism composed of the limiting spring 501, the pull rod 502 and the arc-shaped limiting plate 503 has a simple and reliable structure. The limiting spring 501 provides elastic force, so that the arc-shaped limiting plate 503 can be inserted into the outer slot 402 of the protrusion plate 401 under normal conditions, thereby limiting and fixing the anti-collision plate 4. When the anti-collision plate 4 needs to be replaced, the pull rod 502 is pulled to drive the arc-shaped limiting plate 503 to move against the elastic force of the limiting spring 501, thereby releasing the limitation on the anti-collision plate 4. The operation is convenient, no complicated tools are required, the replacement difficulty is reduced and the replacement speed is increased.

[0027] The end of the convex plate 401 is provided with a top-receiving groove 6. A top-opening spring 602 is fixedly installed on the inner wall of the groove 101. One end of the top-opening spring 602 is fixedly connected to a top-opening plate 601. One end of the top-opening plate 601 abuts against the inner wall of the top-receiving groove 6. Through the cooperation of the top-receiving groove 6 at the end of the convex plate 401 with the top-opening spring 602 and the top-opening plate 601 on the mounting plate 1, when the anti-collision plate 4 is disassembled, after the arc-shaped limiting plate 503 is released, the elastic force of the top-opening spring 602 pushes the top-opening plate 601, and then pushes the convex plate 401, so that the anti-collision plate 4 automatically pops out a certain distance, which is convenient for workers to hold, further saving disassembly time and manpower, and improving the efficiency of replacing the anti-collision plate.

[0028] The end of the protruding plate 401 has an arc-shaped chamfer 4011 structure. The arc-shaped chamfer 4011 structure at the end of the protruding plate 401 plays a guiding role when installing the anti-collision plate 4. When the protruding plate 401 is inserted into the groove 101, the arc-shaped chamfer 4011 will contact the arc-shaped limiting plate 503 and push it to move, making it easier for the arc-shaped limiting plate 503 to avoid, so that the protruding plate 401 can smoothly enter the groove 101. At the same time, it also reduces the wear on the limiting mechanism during the installation process, making the installation operation smoother and improving the convenience of installation.

[0029] The shock absorption mechanism includes a buffer cylinder 7, which is fixedly installed on the gantry crane support 2. A buffer spring 701 is fixedly connected to one end of the buffer cylinder 7, a damper 702 is fixedly connected to one end of the buffer spring 701, and a connecting rod 703 is fixedly connected to one end of the damper 702. One end of the connecting rod 703 is movably inserted inside the buffer cylinder 7, and the other end of the connecting rod 703 is fixedly connected to one side of the mounting plate 1. Through the shock absorption mechanism composed of the buffer cylinder 7, the buffer spring 701, the damper 702, and the connecting rod 703, the shock absorption effect can be fully utilized when the anti-collision plate 4 is impacted. The buffer spring 701 absorbs the impact energy, and the damper 702 slows down the speed of impact force transmission through its own damping characteristics, further enhancing the buffering effect. Through the multi-stage buffer design, the gantry crane support 2 can be more effectively protected from impact damage, ensuring the structural safety and stable operation of the gantry crane.

[0030] One end of the pull rod 502 is fixedly connected to a pull plate 504. By fixing the pull plate 504 to one end of the pull rod 502, it is convenient for the operator to pull the pull rod 502, making it more comfortable and convenient for the operator to apply force. It can more easily overcome the elastic force of the limit spring 501 and realize the operation of the arc-shaped limit plate 503, thereby improving the efficiency and convenience of replacing the anti-collision plate 4.

[0031] The side of the anti-collision plate 4 is provided with a grip 403. By providing a grip 403 on the side of the anti-collision plate 4, workers can easily operate by holding the grip 403 when disassembling and installing the anti-collision plate 4. This allows for better control of the movement of the anti-collision plate 4, reduces the difficulty of operation, and improves the work efficiency of replacing the anti-collision plate.

[0032] Working principle:

[0033] When the hoist 3 moves laterally with the cargo, if the control distance is not in place, the cargo or the hoist 3 will collide with the anti-collision plate 4. The anti-collision plate 4 can drive the mounting plate 1 to move. The mounting plate 1 will drive the connecting rod 703 and the damper 702 to slide inside the buffer cylinder 7. When the damper 702 slides, it will squeeze the buffer spring 701, thereby buffering the impact of the cargo or the hoist 3.

[0034] When the anti-collision plate 4 is damaged and needs to be replaced, by pulling the pull plate 504 forward, the pull rod 502 and the arc-shaped limiting plate 503 can be moved forward, which can release the arc-shaped limiting plate 503 from the external slot 402 limit. Under the elastic force of the push-opening spring 602, the anti-collision plate 4 can be pushed to move. The worker can remove the anti-collision plate 4 by holding the handle 403.

[0035] When reinstalling, insert the protruding plate 401 of the anti-collision plate 4 into the inside of the groove 101. The arc-shaped chamfer 4011 can push the arc-shaped limiting plate 503 to move. Under the elastic force of the limiting spring 501, the arc-shaped limiting plate 503 can be reset and inserted into the inside of the outer slot 402, thus completing the installation of the anti-collision plate 4. Both installation and disassembly are very convenient.
