Conduit penetrating control system, method and underground excavation trolley

Abstract

The invention relates to a guide pipe driving-in control system and method and an underground excavation trolley. The guide pipe driving-in control system comprises a wireless remote control device (10), a wireless receiver (20), a controller (30) and an electric control hydraulic valve (40), wherein the wireless remote control device (10) is connected with the wireless receiver (20) through radio communication signals and is used for sending an operation instruction to the wireless receiver (20) in a wireless manner; the controller (30) is in signal connection with the wireless receiver (20) and the electric control hydraulic valve (40) respectively; and the electric control hydraulic valve (40) is arranged in a working oil path of a guide pipe driving-in working mechanism (50) and is used for controlling positioning and driving-in movement of the guide pipe driving-in working mechanism (50). By adopting the guide pipe driving-in control system and method and the underground excavation trolley, an operator can leave a working seat and reach the front end of a rock drilling machine to carry out remote control; in a guide pipe positioning process, a guide rod can be conveniently and rapidly positioned; and the working efficiency is increased, and the efficiency of driving in the guide rod and the positioning precision are improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a control system and method for driving a conduit and an underground excavation trolley. Background technique [0002] When adopting underground excavation method for subway construction, the initial support of large section of underground excavation is an indispensable link. At present, grids and anchor shotcrete are mainly used as the initial support means. After the grids are placed, the advanced conduits are driven in. The requirements for driving ahead conduits are relatively strict. The distribution of the conduits on the cross-section and the penetration depth will directly affect the quality of primary support for large sections. The protection effect is not good, which affects the construction quality. [0003] At present, there are mainly two ways to drive the advanced conduits in the underground excavation construction. One is to manually drive the conduits with ...

AI Technical Summary

Problems solved by technology

[0006] 1. Due to the long distance between the tunnel working face and the control console of the underground excavation trolley, when the operator sits on the operating seat to drill the conduit, the front-end mechanism of the rock drill blocks the line of sight, so that the operator is not aware of the distance and angle between the propulsion beam and the support surface. Good confirmation, resulting in inaccurate catheter positioning

[0007] 2. The whole machine has no controller and display, and the logic control of the rock drilling machine is mainly realized by switching relays. The reliability is not high. The data collected by the sensor cannot be closed-looped with the controller, nor can it perform human-computer interaction, and the operation accuracy is low.
