Abstract

The invention relates to a movable back-jacking device, and belongs to the technical field of lifting devices. The movable back-jacking device comprises a top supporting plate, a hydraulic back-jacking device body, a supporting piece and a movable base, wherein the top supporting plate is fixedly arranged at the top end of a plunger of the hydraulic back-jacking device body, the hydraulic back-jacking device body is fixedly arranged at the top end of the supporting piece, and the bottom end of the supporting piece is arranged at the top end of the movable base. According to the movable back-jacking device, a fixing piece can be loosely and tightly adjusted to realize the assembly and disassembly of the supporting piece, the height of the hydraulic device is manually adjusted, the top supporting plate arranged in the upper portion can be used for dispersing the load force, the whole back-jacking device can realize 360-degree omnibearing movement through the movable base, and therefore,the back-jacking device has the effects of being adjustable, movable, easy and convenient to operate, high in adaptability and accurate in back jacking.

Description

technical field [0001] The invention relates to a movable jacking device, which belongs to the technical field of lifting devices. Background technique [0002] The traditional jacking device is composed of steel pipes and wooden beams. During the construction process, steel pipes or wooden beams of non-standard sizes are required, resulting in waste of materials and difficulty in turnover. The operation is cumbersome and affects the construction period. It is difficult to control the accuracy of partial jacking. , leading to inaccurate load distribution and affecting construction safety. Contents of the invention [0003] Aiming at the technical problems existing in the application of the existing movable jacking device, the present invention provides a movable jacking device, that is, a movable base is arranged at the bottom of the jacking device to realize the directional movement and precise positioning. [0004] The technical scheme that the present invention adopts...
