Technical field
It is specially a kind of based on the new of laser ranging technique the utility model is related to a kind of tunnel surrounding deformation detecting device
Type tunnel surrounding deformation detecting device.
Background technology
Requirement with modern people to go off daily, tunnel traffic cause flourish, but because tunnel surrounding shape
The serious life security for threatening people of cave-in accident caused by change, but, current existing tunnel surrounding shape changing detection
System cannot be satisfied requirement of the people to safety.Tunnel surrounding shape changing detection is a long-term task, and urban economy builds peace
More harsh requirement is proposed to the real-time and accuracy of modern tunnel surrounding shape changing detection entirely.And current manual static
It checks, sensor detection, the detection methods such as ultrasonic wave need to install signal receiving device at target, and cost is higher, automation
Degree is low, and is easier to be influenced by wagon flow sound wave in tunnel, and measurement error is big.
Utility model content
Problem to be solved in the utility model is to design the degree of automation higher, and measurement cost is lower, accuracy of detection
Higher tunnel surrounding deformation detecting device.
In order to solve the above technical problems, the utility model uses a kind of novel tunnel country rock based on laser ranging technique
Deformation detecting device specifically includes the laser ranging system with pulley that can be moved according to predetermined sliding rail.It is characterized in that, institute
Two parallel orbits that sliding rail is affixed to above tunnel structure are stated, are had by motor-driven above the laser ranging system
Pulley, the pulley can be driven by motor and be slidably reciprocated along planned orbit, and the laser ranging system can independently be translated along track
Movement, completion are detected whole tunnel surrounding structure.
As the further technical solution of the utility model, the track disposed in advance in tunnel should be with corresponding pulley phase
Match.
As the further technical solution of the utility model, disposed in advance in pulley appended by laser ranging system and tunnel
Two parallel orbit contacts.
As the further technical solution of the utility model, pulley sliding slot is chimeric mutually with track, in laser ranging
Device ensures its kinetic stability when being moved along parallel track.
Compared with existing tunnel country rock deformation detecting device, the utility model have the advantage that for：When in face of tunnel
Middle vehicle flowrate is larger, and noise sound wave is disorderly, and when artificial detection or ranging method of sound wave detection are difficult to be detected work, the practicality is new
Type can effectively solve detection difficulty height, and efficiency is low, the not high problem of accuracy in detection.And laser ranging is to detecting environmental requirement
It is low, while cost is also cheaper, is more advantageous to and saves tunnel surrounding testing cost, improves detection efficiency.
