Description

Technical Field

[0001] The invention relates to the technical field of auxiliary facilities for construction engineering, in particular to an asymmetric loading preloading device for a hanging basket for a cantilever casting construction of a bridge. Background Art

[0002] Bridges generally refer to structures built on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are built across mountain streams, poor geology or to meet other traffic needs to make passage more convenient. Bridges are generally composed of superstructures, substructures, supports and auxiliary structures. The superstructure is also called the bridge span structure, which is the main structure for crossing obstacles. The substructure includes abutments, piers and foundations. The supports are force transmission devices installed at the supporting places of the bridge span structure and the piers or abutments. The auxiliary structures refer to the bridge head slab, conical slope protection, revetment, diversion engineering, etc.

[0003] Most of the tripods used in the existing hanging basket asymmetric loading preloading devices are fixed structures, and the angle of the tripod cannot be freely adjusted and fixed, resulting in the need to use different tripods at different angles, which in turn leads to poor compatibility of the tripods, causing more economic expenses for the company.

[0009] As a preferred technical solution of the present invention, one end of the rotating shaft is installed at the center of the outer surface of the gear, and the other end extends out of the outer surface of the vertical frame through the socket, which better enhances the balance of the overall device and effectively enhances the flexibility of use of the overall device.
