Intelligent rock drilling device suitable for narrow and small space of tunnel

Abstract

The invention relates to the technical field of tunnel construction, in particular to an intelligent rock drilling device suitable for a narrow tunnel space, which comprises a drill arm, a first signal induction block, a second signal induction block, a single chip microcomputer, a power supply and an alarm, and the first signal induction block and the second signal induction block are the same in internal structure and each comprise a sliding chute, a magnet, a coil and an elastic piece. The magnet is in sliding connection with the inner wall of the sliding groove, the tail end of the elastic piece is fixed to the tail of the sliding groove, the head end of the elastic piece is fixed to the tail end of the magnet, the coil is fixed to the sliding groove walls on the two sides of the head end of the magnet, the two ends of the coil are connected with pins of the input end of the single-chip microcomputer, and the output end of the single-chip microcomputer is connected with the alarm and the input end of the power source. Compared with the prior art, the function of continuously detecting and filtering interference signals during normal work is achieved at low cost, and the danger that constructors encounter rockfall is avoided.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an intelligent rock drilling device suitable for narrow spaces in tunnels. Background technique [0002] Due to geographical, economic and other factors, obstacles such as mountain peaks cannot be completely avoided in the process of infrastructure construction such as railways, highways, and waterways. Sometimes it is necessary to cross mountain peaks and tunnel excavation must be used. Tunnel excavation is a time-consuming, difficult and challenging construction operation. At present, tunnel excavation mainly adopts the excavation method and the drill and blast method. The excavation method adopts the shield tunnel boring machine for construction, and the entire tunnel section (usually a circular surface) is excavated at one time. The excavation construction method has the advantages of fast excavation and safe working environment, but the disadvantage is that the s...

AI Technical Summary

Problems solved by technology

[0003] Weaknesses of traditional drilling and blasting construction equipment have some disadvantages: it can only detect the rock structure before construction, predict the risk of excavation, and cannot deal with the large area of ​​rock loss caused by the change of rock structure caused by construction. safety risks to construction workers

[0005] However, the rock drilling robot has high cost and cannot reasonably cope with the pressure signal changes caused by the external force encountered by the drilling arm itself.

When the drill arm itself encounters other external forces, such as the collision of construction personnel, the vibration signal received by the drill arm will interfere with the vibration signal transmitted by the drill bit when digging holes, affecting the judgment of the construction personnel, so there is an urgent need for a device that can A device that realizes continuous detection and filtering of interference signals during normal work during the excavation construction process, so as to prevent construction workers from encountering the danger of falling rocks
