Problems solved by technology

[0006] 1. There is no structure designed to enable the main truss of the hanging basket to accurately realize longitudinal sliding and vertical lifting, and the installation accuracy needs to be improved
[0007] 2. There is no structure designed to adjust the levelness of the main truss of the hanging basket. Once the levelness of both ends is uneven during the position adjustment of the main truss of the hanging basket, the installation of the main truss and the main beam of the hanging basket cannot be quickly realized, which not only reduces the Construction efficiency, while needing to waste more time to readjust the position of the main truss of the hanging basket, increasing the construction cost

The measuring assembly is arranged at the top of the base, the sliding device is arranged in the bearing frame and used for sliding a hanging basket main truss, the sliding device comprises a carrying table, a push-pull assembly and two locking assemblies, the carrying table is arranged in the bearing frame in a sliding mode, the push-pull assembly is arranged below the carrying table, and the two locking assemblies are symmetrically arranged at the two ends of the carrying table; according to the longitudinal sliding and vertical lifting mechanism of the large-tonnage guy cable hanging basket main truss, the accuracy of longitudinal sliding and vertical lifting of the hanging basket main truss can be guaranteed, and the installation accuracy and the installation efficiency of the hanging basket main truss are improved.

Description

technical field [0001] The invention relates to the field of construction auxiliary equipment, in particular to a longitudinal sliding and vertical lifting mechanism of a main truss of a large-tonnage cable hanging basket. Background technique [0002] With the rapid development of bridge construction in our country, the construction of cable-stayed bridges has sprung up like mushrooms after rain. The main girder of a cable-stayed bridge is the most important part of the bridge. The quality of its construction is directly related to the success or failure of the bridge construction, and it is also related to the structural stress, line shape, and internal force distribution of the whole cable-stayed bridge. affect the performance of the bridge structure. [0003] The main girder construction techniques of cable-stayed bridges include hanging basket construction at the front fulcrum, hanging basket construction at the rear fulcrum, and bracket construction. Among them, th...
