Abstract

The invention discloses a railway tunnel limit detection method, which comprises an integrated moving mechanism and an assembled moving mechanism, a detection arm is fixed between the integrated moving mechanism and the assembled moving mechanism through a clamping groove and a bolt, a folding shaft is fixed on the contact part of the detection arm through a screw, the folding shaft is fixed to the integrated moving mechanism through fixing bolts, stepping motors are arranged at the left side of the integrated moving mechanism, limit measuring instruments are arranged above the stepping motors, the range of charge of the limit measuring instruments is 90 degrees, two sets of stepping motors and two sets of limit measuring instruments are arranged, and the management end is arranged on the right sides of the stepping motors. The management end is composed of a CPU, a track gauge detection sensor, a tilt angle sensor, Bluetooth and a control chip, a handle is arranged in the right side of the management end and provided with a trigger, and the trigger is connected with one end of a connecting belt. The railway tunnel limit detection method has the advantages that the method is practical, portable and easy to carry, manual pushing is not needed, and rapid clearance detection operation of planing at any position of a tunnel is automatically achieved.

Description

technical field [0001] The invention relates to the technical field of railways, in particular to a detection method for railway tunnel boundaries. Background technique [0002] The railway tunnel gauge is one of the approaching gauges of railway buildings. In order to ensure that the train has enough driving space and driving safety when running in the tunnel, except for the rolling stock and the buildings and equipment that interact with the rolling stock, other buildings and equipment shall not be intruded within the limit. It can be seen that the tunnel is close to the limit detection It is of great significance to the safe operation of the railway. In recent years, along with the rapid development of electronic technology and computer technology, limit detection products based on new technologies have been introduced continuously, which can better meet the needs of limit detection operations. [0003] Existing tunnel limit detection devices are relatively heavy and un...
