Abstract

The invention discloses a jack. The jack comprises moving wheels, a frame body, a first hydraulic motor, a second hydraulic motor, a telescopic arm and a rotating disc, wherein the moving wheels are arranged at the bottom of the frame body, and the first hydraulic motor is connected with the bottom of the frame body; the second hydraulic motor is connected with the rotating disc, the telescopic arm is connected with the rotating disc, the second hydraulic motor drives the rotating disc to rotate, and the rotating disc drives the telescopic arm to rotate synchronously. The jack can move through the moving wheels, the telescopic arm can go deep into narrow space for operation, so that the problem of potential safety hazards caused by personnel entering operation is avoided, the operation efficiency can be improved, and use is more convenient.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a jack. Background technique [0002] When the steel strand is installed on the bridge, in the narrow space, large jacks cannot enter, and manual work in the air is required, which poses a great safety hazard, is particularly inconvenient to use, and has low efficiency and cumbersome operation. Contents of the invention [0003] For this reason, the present invention provides a jack to solve the problems in the prior art that manual entry into a narrow space is required, resulting in relatively large safety hazards and low efficiency. [0004] In order to achieve the above object, the present invention provides the following technical solutions: [0005] According to the present invention, a jack is provided, comprising a moving wheel, a frame body, a first hydraulic motor, a second hydraulic motor, a telescopic arm and a turntable, wherein the moving wheel is provi...
