Automatic measurement and error correcting system for heading machine

Abstract

The invention discloses an automatic measurement and error correcting system for a heading machine. The system is composed of a PLC control system, a tilt angle sensor, an electronic compass, a laser pointing instrument, a displacement sensor, a human-computer interaction module and a driving mechanism. All modules are connected by a communication cable and a control cable. On the basis of positioning of a three-dimensional position coordinate of a heading machine and calculation and analyses by the PLC control system, automatic measurement and error correcting control can be completed by the heading machine, thereby substantially improving the efficiency, precision, and security of the heading work.

Description

technical field [0001] The invention relates to the traveling track measurement and deviation correction control of a roadheader, in particular to an automatic measurement and deviation correction system of a roadheader. Background technique [0002] A roadheader is a special construction machine for tunneling. Modern roadheaders integrate machinery, electricity, hydraulics, sensors, and information technology, and have the functions of excavating and cutting soil, conveying soil, and assembling tunnel linings. Roadheaders have been widely used in subway, railway, highway, municipal, hydropower tunnel projects. [0003] As the most important equipment in tunnel mechanized excavation, the roadheader's working condition directly affects the construction quality. In actual construction, whether the roadheader is in the process of walking or in the process of operation, its running track will always deviate from the axis of the roadway. In terms of the track measurement and dev...

AI Technical Summary

Problems solved by technology

In actual construction, whether the roadheader is in the process of walking or in the process of operation, its running track will always deviate from the axis of the roadway. In terms of the track measurement and deviation correction control of the roadheader, the current roadheader still uses manual Measurement and manual deviation correction, due to the harsh excavation environment, poor working conditions, and being affected by dust, water mist, etc., this method not only has poor safety and heavy workload, but also severely tests the experience and operation skills of the operators. If there is a certain deviation in the results of measurement and correction, it will not be consistent with the design trajectory to a high degree, thus affecting the quality of the project
