Non-settling electric hydraulic lifting supporting device

Abstract

The invention discloses a non-settling electric hydraulic lifting supporting device, which comprises a base; a lower supporting barrel, a middle supporting barrel and an upper supporting barrel are fixedly connected to the upper part of the base in sequence from bottom to top; a hydraulic pump station is arranged on the base and the lower supporting barrel; a hydraulic control integrated valve block is arranged on the hydraulic pump station; a hydraulic cylinder vertically fixed in the lower supporting barrel and the middle supporting barrel is arranged above the base, and the hydraulic cylinder is connected with the hydraulic control integrated valve block through an oil pipe; an inner supporting barrel capable of sliding up and down in the upper supporting barrel is arranged at the top of a piston rod of the hydraulic cylinder; the top of the inner supporting barrel extends out of the exterior of the upper supporting barrel and is provided with a support seat; and a vertical fine tuning mechanism is arranged at the upper end of the upper supporting barrel, and a positioning barrel supported on the vertical fine tuning mechanism is arranged on the vertical fine tuning mechanism and the support seat. Through the device, a huge heavy object can be conveniently lifted, and the object can be kept at a height and is not settled after the huge heavy object is lifted to a certain height.

Description

technical field [0001] The invention relates to a lifting support device, in particular to an electro-hydraulic lifting support device without subsidence. Background technique [0002] At present, some large electromechanical equipment with large volume and heavy weight, such as airplanes, large vehicles, ships, etc., often need to be lifted and supported to maintain a certain height during installation, commissioning, and maintenance. Subsidence is not allowed. To achieve these requirements, it is often difficult to meet the power requirements with mechanical transmission devices, and it is impossible to meet the requirements of constant support height for a long time with hydraulic transmission. Contents of the invention [0003] The object of the present invention is: aiming at the deficiencies of the prior art, to provide an electro-hydraulic lifting support device that will not sink, the device can not only lift and lift huge heavy objects conveniently, but also can l...
