[0002] In the construction of variable cross-section continuous beam bridges, the cantilever casting construction method of the hanging basket is relatively common. However, the control of the traveling condition of the hanging basket structure has always been the top priority of the hanging basket construction. Most hanging baskets use traveling wheels combined with jacking to move forward. Therefore, the traveling limit structure is undoubtedly another barrier to the safety of the traveling structure, which can effectively prevent the phenomenon of excessive traveling distance. However, at present, most of them achieve the limit by welding relevant structures on the traveling track, which is not conducive to the reuse of the materials of the traveling track. And when the hanging basket moves forward and reuses the track beam during the construction of each beam segment, to a certain extent, it increases the difficulty of the hanging basket traveling; at present, there are also some that fix the upper limit device by drilling holes on the side of the traveling track steel rail and then passing a connecting rod through the holes and fixing it with nuts, which will cause great damage to the structure of the track beam and is not conducive to safe construction. Therefore, the utility model designs a more convenient, efficient, safe and reusable device for limiting the traveling of the hanging basket. Content of the Utility Model
