Abstract

The invention discloses a pipe connecting device, comprising a main frame, wherein rollers are arranged at the bottom of the main frame, two parallel pipeline fine-tuning devices are arranged on the main frame in a slidable manner, each pipeline fine-tuning device is provided with a first port and a second port which are communicated, the distance between each first port and the corresponding second port is adjustable, each first port is connected with a first hose, each second port is connected with a second hose, and a hydraulic gate valve is arranged on each second port. By adopting the pipe connecting device, pipelines can be connected conveniently, the pipe connecting time can be reduced, the labor intensity of workers is reduced, and the working efficiency is increased.

Description

technical field [0001] The invention relates to tunnel construction equipment, in particular to a connector for connecting extended steel pipes and hoses. Background technique [0002] With the rapid development of my country's underground space development and utilization, there are more and more construction projects such as subway tunnels, highway tunnels, and municipal pipelines. Most of these projects use large-diameter mud-water balance shield machines for construction. At the same time, a certain pressure water is injected through the ground to generate a certain balance pressure between the cutter head and the soil layer to ensure that the soil layer in front will not collapse. At the same time, the pressure water dilutes the excavated soil and is pumped out by the mud pump to the ground for mud-water separation. Due to the continuous advancement of the shield, the steel pipes that inject pressure water into the front of the shield from the ground and the steel pipes ...
