Route inspection maintenance equipment for sound barrier

Abstract

The invention relates to route inspection maintenance equipment for a sound barrier. The route inspection maintenance equipment comprises a route inspection trolley and a maintenance device. The route inspection trolley is provided with a row of wheels in the sound barrier direction, two limiting plates on one side of the sound barrier and two limiting plates on the other side of the sound barrier; the two limiting plates on the inner side of the sound barrier are provided with detectors respectively and can turn to the inner side of the edge of a trolley body around rotating shafts, and the detectors can judge whether an obstacle exists or not. The route inspection trolley is further provided with a first video module. The maintenance device comprises a clamping base, a plane displacement mechanism and a fastening mechanism; the clamping base is used for being fixed to the top of the sound barrier, the plane displacement mechanism is arranged on the clamping base, the fastening mechanism is arranged on the plane displacement mechanism, the plane displacement mechanism can move the fastening mechanism to any position of a plane, the bottom height of the fastening mechanism can be adjusted, a bolt is fastened through the bottom of the fastening mechanism, and a second video module is arranged at the bottom of the fastening mechanism. The equipment can perform route inspection automatically and fasten the bolt on the outer side of the sound barrier rapidly and safely, and is free of inspection dead points, good in observation effect and low in cost.

Description

technical field [0001] The invention relates to a sound barrier maintenance device, in particular to a sound barrier inspection and maintenance device. Background technique [0002] With the development of my country's high-speed railway industry, the noise pollution along the line is becoming more and more serious. Setting up sound barriers along the railway line is an effective way to reduce noise. The sound barriers are installed on both sides of the line. Due to the repeated action of the train passing through the vacuum and wind pressure, it is easy to cause problems such as loosening of the sound barrier bolts and fasteners, cracking of the foundation mortar, damage to the anti-corrosion layer of the columns, deformation and damage of the sound-absorbing panels, etc. If the maintenance fails If it is discovered in time, it is very likely to affect the safety of train operation, so the sound barrier needs to be inspected regularly. [0003] Sound barriers are generally...

Problems solved by technology

The sound barriers are installed on both sides of the line. Due to the repeated action of the train passing through the vacuum and wind pressure, it is easy to cause problems such as loosening of the sound barrier bolts and fasteners, cracking of the foundation mortar, damage to the anti-corrosion layer of the columns, deformation and damage of the sound-absorbing panels, etc. If the maintenance fails If it is discovered in time, it is very likely to affect the safety of train operation, so the sound barrier needs to be inspected regularly

[0003] Sound barriers are generally installed on railway shoulders or bridge railings. During daily inspections, the inner side of the sound barrier can be directly observed and maintained, while the outer side of the sound barrier cannot be directly observed or maintained. Currently, the following two methods are mainly used: There are several ways to solve this problem: 1) Remove the sound barrier piece by piece by lifting equipment and observe and maintain it accordingly. This method is not only inefficient, but also may cause new 2) Suspension operators observe and maintain outside the sound barrier. Since most high-speed railways are elevated, the distance from the ground can range from a dozen meters to tens of meters, and there is no operating construction platform outside the viaduct pier, so it is necessary to Use ropes to suspend the operator in mid-air, which has great potential safety hazards, high operating costs, and extremely low working efficiency under such operating conditions

The equipment has the following problems: 1) The entire equipment occupies a large area, which affects the operation of other equipment and normal transportation when traveling on the track; The arm must extend out of the sound barrier, and if the operation is a little careless, it will hit the electric pole, which poses a safety hazard; 3) During the working process of the equipment, it must be observed through the video module on the telescopic arm. position, the telescopic arm must be retracted. At this time, the video module cannot observe the specific situation outside the sound barrier, and there is a dead point for detection; 4) The video module on the telescopic arm must be outside the hoisting mechanism, and the hoisting mechanism must be outside the sound barrier. , the video module protrudes too long, and the observation effect is poor; 5) The whole equipment includes the hydraulic system, power system, walking system, video system, etc., the operation is complicated, the cost is high, and the overall implementation is difficult
