Description

Technical Field

[0001] The utility model relates to a quick positioning bracket for an oil jack, belonging to the technical field of positioning brackets. Background Technique

[0002] The prestressed oil jack is a special jack for tensioning prestressed tendons such as steel strands. All prestressed jacks are through-hole hydraulic double-acting jacks. The prestressed jack needs to be used in cooperation with a high-pressure oil pump, and the power for tensioning and jacking back is provided by the high-pressure oil of the high-pressure oil pump. The prestressed jack has a compact structure, stable operation during tensioning, high oil pressure, and large tensile force. It is widely used in prestressed construction projects such as highway bridges, railway bridges, hydropower dams, and high-rise buildings. During use, such as in the construction process of precast box girders, the quality of prestressed construction is particularly crucial, which is directly related to the strength safety and stability of the bridge. During prestressed construction, due to the large stress, the safety risk is relatively high.
