Description

Technical Field

[0001] The utility model relates to the technical field of gantry crane buffering, in particular to a gantry crane limit blocking buffering device. Background Art

[0002] Gantry crane is a variation of bridge crane, commonly known as gantry crane. Its metal structure is like a door-shaped frame, with two legs installed under the main beam, which can walk directly on the ground track, and the two ends of the main beam can have outward cantilever beams. Gantry crane has the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility, and is widely used in subway construction sites.

[0003] At the subway construction site, a gantry crane is needed to lift large components. During operation, the walking part of the gantry crane is erected on the rails on both sides. In order to prevent the gantry crane from running out of the track, the staff usually seals the two ends of the gantry crane's track. However, the gantry crane often encounters the situation where it needs to stop suddenly and generates a large impact force during use. The common rigid sealing of the head end is difficult to ensure the safety of the gantry crane. In addition, some existing rigid sealing methods mostly directly weld the blocking workpiece to the gantry crane track. When the gantry crane directly hits the blocking workpiece, a strong impact will be generated instantly. The blocking workpiece is easily damaged, and the track on which it is located will also be damaged. According to the degree of damage, the track needs to be repaired or maintained, which increases the labor intensity of the workers. Therefore, the utility model proposes a gantry crane limit blocking buffer device to solve the deficiencies in the prior art. Utility Model Content
