Abstract

A continuous jacking device for steel pipes, comprising a jacking frame and an oil cylinder, the oil cylinders are a large oil cylinder and a small oil cylinder, a jacking frame is arranged on the jacking frame, and the jacking frame is divided into a jacking frame and a jacking frame. The jacking front frame and the jacking rear frame are provided with an oil cylinder accommodation chamber between the jacking front frame and the jacking rear frame, and a large oil cylinder coupling frame is arranged on the jacking frame, and the large oil cylinder coupling There is a large oil cylinder on the frame, and the cooperation between the large oil cylinder and the lower oil cylinder makes the jacking operation of the steel pipe more efficient, meets the needs of continuous jacking of the steel pipe, and can carry out continuous jacking operations, making the steel pipe jacking operation more efficient. Jacking saves a lot of time.

Description

technical field [0001] The invention relates to a jacking device, in particular to a continuous jacking device for steel pipes. Background technique [0002] The jacking of steel pipes generally has relatively long pipe joints, ranging from four to five meters in length, and eight to nine meters in length. When jacking, the jacking oil cylinder is stretched out for a stroke, then retracted, and the pad iron is added for jacking. After several cycles like this, until a section of steel pipe is topped in place. During the above-mentioned jacking period, nothing can be done when the jacking oil cylinder is retracted, only waiting, which affects the efficiency of the steel pipe jacking, and can not carry out efficient steel pipe jacking operations well. Contents of the invention [0003] In order to solve the technical problems of low steel pipe jacking efficiency and inability to continuously jack steel pipes in the prior art, the present invention proposes a continuous stee...
