ABSTRACT

The application of pneumatic puncher to underground trenchless pipe laying is the only way for the development of modern society. This machine is the best representative of high technology. It is a new technology with high intelligence. It is a new product and a new way of development. It has a very wide application in the laying of underground pipelines. Therefore, pneumatic perforator has great application value.
Pneumatic puncher is a kind of equipment that can walk in the soil. It is controlled by a computer and enters the soil at one end of the earth surface and penetrates from the specified location at the other end of the surface. The purpose of its control is to make the machine move forward according to the designed track, and to change direction at any time, to bypass obstacles or to correct deviations.
This paper mainly discusses the overall plan of pneumatic piercer, the establishment and analysis of various models, the calculation of the pneumatic impact work, the mechanism analysis of the extrusion effect of the impact head and the research on the related problems of the machine detection and control. In this paper, the current situation of the pneumatic perforator is introduced, and the working conditions and the wear of the machine are introduced. Ground experiments to establish a model. The movement process is analyzed.
Key words: perforator; trenchless technology; pneumatic impact; trajectory controllable.
