Miniature rock pipe jacking machine with replaceable cutter head and mud bin

Abstract

The invention discloses a miniature rock pipe jacking machine with a replaceable cutter head and a mud bin. The pipe jacking machine comprises a front cylinder, the front end of the front cylinder isfixedly sleeved with a connecting cylinder, the rear end of the front cylinder is fixedly sleeved with a rear cylinder, and a cone crushing mud bin is fixedly connected to the front end of the connecting cylinder through bolts; a power system is fixedly installed in the front cylinder, the power system includes a motor and a speed reducer connected to the motor, one end of the speed reducer is provided with a power output shaft, a hob cutter head is fixedly installed on one end of the power output shaft, and the hob cutter head is located in the cone crushing mud bin. The pipe jacking machinecan adapt to rock stratums as well as silt soft soil stratums, and the tunneling efficiency is ensured. The installation and removal are simple and convenient, the safety is ensured, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of pipe jacking machines, and relates to a miniature rock pipe jacking machine with a replaceable cutter head and a mud bin. Background technique [0002] With the development of the country's underground pipeline network, the demand for pipe jacking machines is increasing. my country has a vast territory and complex engineering geology and hydrogeology conditions. Pipe jacking is used in various strata, such as soft soil, silt, sand, pebbles and rocks. Due to the complex geological conditions, each project should select the appropriate pipe jacking equipment according to the hydrological and geological conditions of the project. It is particularly important for a pipe jacking machine to adapt to various geological conditions as much as possible. [0003] At present, the miniature pipe jacking machines for crushing rocks in China have slow tunneling efficiency when dealing with ordinary soft soil and silt formations...

AI Technical Summary

Problems solved by technology

[0003] At present, the miniature pipe jacking machines for crushing rocks in China have slow tunneling efficiency when dealing with ordinary soft soil and silt formations. In severe cases, rock cutter heads are prone to mud cakes.

When encountering projects with different geology, it is necessary to purchase multiple pipe jacking machines to deal with different strata, which greatly increases the construction cost
