Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for replacing the track of a gantry crane, and specifically discloses a hanging frame for replacing the track of a gantry crane. Background Technique

[0002] In the operation of replacing the trolley track of a container gantry crane, the hoisting of the track is a high-risk operation link. Each gantry crane needs 20 tracks to be replaced as a whole. Each track is 12 meters long and weighs about 1 ton. Due to high-altitude operation, small operation area of the bearing rail beam, and interference of many structural parts on the vertical hoisting path, there is no reliable hoisting anchoring point on the gantry crane girder.

[0003] To solve the above problems, the patent with the publication number CN217437544U discloses a special tool for replacing the trolley track of a container quay crane, which includes a limiting strip and a hoisting beam arranged in sequence above the trolley track on the quay bridge girder. The length direction of the limiting strip is the same as the length direction of the trolley track, and the length direction of the hoisting beam is perpendicular to the length of the trolley track. At least two hoisting beams are arranged at intervals along the length direction of the trolley track; the hoisting beam is detachably installed on the quay bridge girder, and a hoisting mechanism for hoisting the trolley track is arranged on the hoisting beam. Two stop blocks are correspondingly arranged at the left and right ends of the hoisting beam, and there is a limiting gap for cooperating with the quay bridge girder between the two stop blocks; a fixing mechanism for cooperating with the limiting strip is arranged at the position corresponding to the limiting strip on the hoisting beam.

[0004] In the above solution, the hoisting beam needs to be placed on the quay bridge girder in advance. Although the length of the hoisting beam is shorter than that of the trolley track, it still cannot be carried and transported manually. As a result, hoisting equipment such as a chain block is still needed to hoist the hoisting beam in advance, and a hoisting anchoring point still needs to be installed for the chain block. Eventually, the operation is still cumbersome and the track replacement efficiency is not high. Moreover, in the above solution, there is no place to hang the safety rope during personnel operation, which poses a safety hazard. Content of the Utility Model

[0005] In view of the above deficiencies of the prior art, the utility model provides a hanging frame for replacing the track of a gantry crane to solve the problems of cumbersome operation and low track replacement efficiency.
