[0029] The present invention will be described in detail below with reference to the drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0030] Embodiment. This embodiment aims to provide an anti-collision device for a gantry crane, and its main function is reflected in that it can effectively protect the legs of the gantry crane and the hoisted goods from being damaged by impact and avoid causing potential safety hazards.

[0031] Refer to Figures 1-4 , including: a pair of angle plates, a support arm and a buffer plate 3. The two angle plates are respectively arranged on two adjacent legs of the gantry crane, and the corners of the angle plates correspond to the edges of the legs of the gantry crane. The angle plate is composed of a pressure plate 1 and an abutting plate 2. Specifically, the edges between the pressure plate 1 and the abutting plate 2 are perpendicularly welded and butted together to form a right-angled angle plate. Among them, the pressure plate 1 is externally pressed against the opposite side of two adjacent legs of the gantry crane, and the abutting plate 2 is closely attached to the side of the leg of the gantry crane facing the electric hoist.

[0032] Refer to Figures 2-4, The support arm is horizontally arranged between the pressure plates 1 of the two angle plates and centered. The end of the support arm is hinged to the corresponding pressure plate 1 so that the angle plate swings along the axial direction of the support arm. The function of the angle plate swing is to adapt to the gantry crane legs in different support forms, effectively improving the applicable range of the device. Specifically, the support arm includes: a threaded rod 5 and a pair of sleeves 6. Sleeves 6 are threadedly sleeved on the outer parts of both ends of the threaded rod 5. The end of the sleeve 6 away from the threaded rod 5 is hinged to the corresponding pressure plate 1. The thread directions on the outer parts of both ends of the threaded rod 5 are opposite, so that when the threaded rod 5 rotates, it drives the two sleeves 6 to move synchronously in the opposite direction. A plurality of hand rods 7 are distributed along the circumferential direction in the middle of the threaded rod 5. The hand rods 7 facilitate the staff to rotate the threaded rod 5 to adjust the distance between the two sleeves 6, and further adjust the length of the support arm spanning between the two angle plates to adapt to the gantry crane legs with different distances. At the same time, the position of the angle plate on the gantry crane leg is stably fixed by the support arm.

[0033] Refer to Figure 4 and Figure 5 , The buffer plate 3 is arranged parallel to the front of the abutting plate 2. An elastic plate 4 is arranged between the buffer plate 3 and the abutting plate 2. When the goods swing near the gantry crane leg or first hit the buffer plate 3, the elastic plate 4 between the buffer plate 3 and the abutting plate 2 can effectively reduce the impact, thereby protecting the gantry crane leg and the goods themselves from being damaged. Specifically, the end of the buffer plate 3 is flush with the end of the abutting plate 2, and their specifications are the same, which is convenient for processing. The elastic plate 4 is a corrugated buffer spring, and the extending direction of the corrugation of the elastic plate 4 is consistent with the length direction of the buffer plate 3. Among them, at least a pair of elastic plates 4 are arranged between the abutting plate 2 and the corresponding buffer plate 3, and the peak of one elastic plate 4 corresponds to the valley of the other elastic plate 4, so that the peaks of the two elastic plates 4 are respectively welded and fixed to the corresponding abutting plate 2 or buffer plate 3. This setting uses the elastic plate 4 as the medium for connecting the buffer plate 3 and the abutting plate 2, and makes the welding points between the elastic plate 4 and the abutting plate 2 and the buffer plate 3 dense and orderly, thereby ensuring the firm and stable connection between the buffer plate 3 and the abutting plate 2 and effectively improving its service life.

[0034] In this embodiment, the end of the elastic plate 4 is flush with the end of the abutting plate 2, ensuring that the acting space of the elastic plate 4 covers the interval between the abutting plate 2 and the buffer plate 3 and ensuring the anti-collision effect of the device.

[0035] In actual application, when the goods near the gantry crane leg swing due to improper operation of the staff or a sudden power failure, the goods will first hit the buffer plate 3. The buffer plate 3 squeezes the elastic plate 4, and the impact is reduced by the elastic deformation ability of the elastic plate 4, ensuring that the gantry crane leg will not be damaged. On the contrary, the goods will not be damaged when they do not directly hit the gantry crane leg. The use effect is excellent, effectively maintaining the stability of the gantry crane hoisting system and ensuring the installation and hoisting.

[0036] The anti-collision device provided in this embodiment can effectively reduce the impact on the legs of the gantry crane when the suspended goods swing, ensuring the stability of the gantry crane. Correspondingly, it also reduces the damage suffered by the goods themselves, protects the integrity of the goods, and further avoids potential safety hazards.

[0037] It can be understood that the above description is only exemplary, and the embodiments of the present application do not limit this.

[0038] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are within the scope of the claims of the present invention awaiting approval.
