Technical Field

[0001] The utility model relates to the technical field of hydraulic lifting platforms, in particular to a steel gallery hydraulic lifting platform. Background Art

[0002] In the field of construction technology, buildings with corridor structures emerge in an endless stream. In order to highlight the novelty of the building's appearance and the diversity of its functions, a steel corridor is set up between two adjacent buildings. The steel corridor is an important structural form in modern buildings, which realizes the expansion of space and the improvement of functions.

[0003] The hydraulic lifting platform for steel corridors is a device used to connect two or more buildings during construction. It uses hydraulic technology to lift the steel structure corridor as a whole to a specified position. As shown in the prior art of publication number CN115559429A, although the prior art starts the double-headed motor, the driving end of the double-headed motor drives the threaded rod to rotate clockwise, so that the threaded rod drives the moving plate and the clamping plate to move toward the outer wall of the hydraulic lifter, so that the clamping plate completes the fixation of the hydraulic lifter, thereby ensuring the stability of the hydraulic lifter during operation. However, the prior art can only fix the two sides of the hydraulic lifter, resulting in the hydraulic lifter still shaking up and down, which leads to the lack of reliability of the technical solution and certain limitations. Utility Model Content

[0004] To this end, an embodiment of the utility model provides a steel corridor hydraulic lifting platform to solve the problem of insufficient stability caused by the incomplete fixing method in the prior art.
