Control system for suspending hole drilling trolley for subway tunnel and control method

Abstract

Provided are a control system for a suspending hole drilling trolley for a subway tunnel and a control method. The control system comprises a power module (10), a trolley travelling module (20), a travelling distance module (30) and a hole drilling driving module (40); the power module (10) is used for supplying working voltage to the control system; the trolley travelling module (20) is used for controlling forward rotating, backward rotating and stopping of a trolley travelling motor (7.1) and starting and stopping of a braking electromagnetic valve (4.1); the travelling distance module (30) is used for detecting and controlling the travelling distance and braking condition of the trolley; and the hole drilling driving module (40) is used for controlling starting and stopping of a motor of a percussion drill (2.1) and forward rotating, backward rotating and stopping of a driving pushing rod (2.2). The control system and the circuit control method can control hole drilling, distance measuring and positioning of the trolley continuously and automatically, automation of hole drilling is achieved, the efficiency of hole drilling is greatly improved, labor intensity is reduced, and the quality of hole drilling is improved.

Description

technical field [0001] The invention relates to a tunnel construction machine, in particular to a control system and a control method for hanging a drilling trolley in a subway tunnel. Background technique [0002] In order to alleviate the needs of urban traffic, stimulate the national economy, and also serve as civil air defense, my country has carried out large-scale subway construction in recent years. In the construction of subway tunnels, after the civil works are completed, that is, when the station works start, many specialties need to drill thousands of sets of installation holes on the tunnel wall along the line direction of the tunnel for the installation of different professional cable supports and catenary. For brackets, water supply and drainage brackets, etc., the size of the installation holes and the horizontal and vertical dimensions of each profession are basically the same. see figure 1 with figure 2 ,in figure 1 It shows the brackets that need to be...

AI Technical Summary

Problems solved by technology

For suspension drilling, Chinese invention patent application number 201210151763.7 discloses a tunnel drilling machine, and Chinese utility model patent application number 201320675236.6 discloses a lifting laser positioning high-space boom drilling device. The two technical solutions only It solves the technical problem of punching a single hole without the need for people to climb high, but does not solve the problem of continuous punching automation, which obviously does not meet the needs of automatic punching in subway tunnels

At present, there is no technical solution for a control system and circuit control method that can continuously and automatically control the drilling, distance measurement, and positioning of the control vehicle in the prior art to realize the automation of drilling.
