[0002] Large-scale port cranes, the backbone of port loading and unloading operations, are equipped with a wide variety of safety devices. Windbreaks are a key safety feature, and electric wedges are a standard requirement for windbreaks on special equipment. The wedges of electric wedges are designed to generate friction with the rails, creating a high coefficient of friction and stress to meet windbreak requirements.

A positioning plate is fixedly welded between the upper side wall of the fixed frame near the right end of the curved plate. The aforementioned application document describes a device to prevent the iron wedge from falling off in the event of vibrations generated by the gantry crane during operation. However, the device still has the possibility of the electric iron wedge dislocating when the fixed frame tilts forward or backward, thereby reducing the device's windproof effect.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example 1

[0023] See also Figures 1-4 , a windproof device for port lifting equipment, comprising a fixing frame 100, a connecting plate 200 is mounted on the bottom of the fixing frame 100, and an electric iron wedge 300 is mounted on the side of the fixing frame 100;

[0024] A compression assembly 400 is mounted on the side of the mounting frame 100. This assembly includes a pipe 401 and a pressure chamber 402. When the mounting frame 100 tilts forward or backward, it causes the pipe 401 within it to tilt synchronously. A gravity column 403 is installed within the pipe 401. As the pipe 401 tilts, the gravity column 403 within the pipe 401 moves along the inner wall of the pipe 401 under the influence of gravity. One end of the air pressure chamber 402 is fixedly connected to an elastic air bag 404, and an opening is provided at the bottom of the pipe 401, the cross-sectional shape of the opening is adapted to the cross-sectional shape of the elastic air bag 404, two elastic air bags 404 are provided, and the two elastic air bags 404 are symmetrically distributed about the gravity column 403, and the other end of the air pressure chamber 402 is slidingly connected to a clamping rod 405, and the side of the fixed frame 100 is rotatably connected to a torsion spring rod 406, and a clamping slot 407 is provided on the outside of the torsion spring rod 406, and the clamping rod 405 is located in the clamping slot 407, and the cross-sectional shape of the clamping rod 405 is adapted to the cross-sectional shape of the clamping slot 407, and a clamping block 408 is fixedly connected to the outside of the torsion spring rod 406. When the gravity column 403 moves along the inner wall of the pipe 401, it can squeeze the elastic airbag 404, so that the gas in the elastic airbag 404 is passed into the air pressure chamber 402 fixedly connected to it, so that the pressure in the air pressure chamber 402 increases, driving the clamping rod 405 slidingly connected to the air pressure chamber 402 to move, and the clamping rod 405 moves out of the clamping groove 407 on the torsion spring rod 406, so that the torsion spring rod 406 loses its restriction, and under its own action, drives the clamping block 408 fixedly connected to it to rotate, compressing the two electric iron wedges 300, thereby preventing them from dislocating, thereby improving the windproof effect of the device.

[0025] During use, when the fixing frame 100 tilts toward the front and rear sides, it can drive the pipe 401 inside it to tilt synchronously, and the gravity column 403 in the pipe 401 then moves along the inner wall of the pipe 401 under the action of gravity, and the gravity column 403 then squeezes the elastic airbag 404, so that the gas in the elastic airbag 404 is passed into the air pressure chamber 402 fixedly connected to it, so that the pressure in the air pressure chamber 402 increases, driving the card rod 405 slidingly connected to the air pressure chamber 402 to move, and the card rod 405 moves out of the card slot 407 on the torsion spring rod 406, so that the torsion spring rod 406 loses its restriction, and under its own action, drives the clamping block 408 fixedly connected to it to rotate, thereby clamping the two electric iron wedges 300. Example 2

[0026] See also Figures 1-4 Based on the first embodiment, a reset assembly 500 is provided inside the fixing frame 100. The reset assembly 500 includes an adjustment column 501. A force-bearing plate 502 is fixedly connected to the side of the adjustment column 501. A spring 503 is fixedly connected to the side of the force-bearing plate 502. The end of the spring 503, away from the force-bearing plate 502, is located inside the pipe 401. The spring 503 is fixedly connected to the inner wall of the pipe 401. A through slot 504 is provided on the pipe 401 and the fixing frame 100. When it is necessary to restore the gravity column 403 to its initial position, the adjustment column 501 is rotated, causing the adjustment column 501 to move the force-bearing plate 502 fixedly connected to it. At the same time, the spring 503 pushes the force-bearing plate 502, causing the force-bearing plate 502 to move within the pipe 401 and drive the gravity column 403 on it to return to its initial position, facilitating the next anti-dislocation operation. This does not affect the use of the clamping assembly 400, making the device easier to use.

[0027] During use, based on Example 1, when the gravity column 403 needs to be restored to its initial position, the adjusting column 501 is rotated so that the adjusting column 501 drives the force-bearing plate 502 fixedly connected thereto to move, and at the same time, the spring 503 pushes the force-bearing plate 502 so that the force-bearing plate 502 moves in the pipe 401 and drives the gravity column 403 thereon to return to its initial position.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
