[0002] The ground-mounted double-rocker arm bracket is safe and reliable, has less restrictions on traffic and terrain, and has a high degree of mechanization. In UHV power transmission construction operations, the ground-mounted double-rocker arm bracket is often used to assemble towers without additional wires, and a hydraulic jacking system is used to reduce the risk of high-altitude operations. However, during the construction process of the existing ground-mounted double-rocker arm bracket, workers are required to assemble it on the ground first, and then erect it after the assembly is completed. It does not have its own standing function and often requires manual pulling force or the use of a crane, etc., which is inconvenient and unsafe to use. Therefore, a self-standing jacking frame is needed that can realize its own standing function. Utility Model Content

[0005] The parameters of the hydraulic cylinder are: working pressure ≤ 20Mpa, ear distance range is 2550mm-4700mm, stroke is 2150mm, large end thrust is 301.7KN, small end pulling force is 147.7KN, and the ear distance of the floor-standing double rocker arm lifting frame when it is laid flat and extended before standing up is 4358mm.

[0006] A support A and a support B are arranged opposite to each other at one end of the upper surface of the base, a connecting rod is arranged between the support A and the support B, the support A is hinged with the connecting rod A, the support B is hinged with the connecting rod B, the other ends of the connecting rod A and the connecting rod B are hinged with one end of the hydraulic cylinder, and the connecting rod A, the connecting rod B and the connecting rod form a triangular structure. The hydraulic cylinder is hinged with its triangular structure to increase stability.

[0007] A support C is provided on the upper surface of the base, and one side of the bottom end of the floor-standing double rocker arm lifting frame is hinged to the base through the support C.
