Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of railway tunnel disease treatment, in particular to a railway tunnel disease comprehensive treatment construction operation vehicle. BACKGROUND

[0002] Various diseases of early built heavy load railway tunnels gradually enter the high incidence period, such as cracking, spalling, network cracking, water leakage, frost heaving and other diseases of the tunnel lining arch, as well as diseases such as subsidence, water ditch extrusion and mud boiling of the line subgrade, which have seriously threatened the safety of train operation.

[0003] In order to eliminate the above hidden dangers, the railway maintenance department needs to regularly inspect the line to discover diseases in time and treat them accordingly. The construction difficulty of installing the inner ring of corrugated plates in the process of treating the cracking disease of the tunnel lining arch and pre-burying pipes in the ballast in the process of treating the subsidence disease of the line subgrade is relatively large.

[0004] At present, in the process of treating the cracking disease of the tunnel lining arch, the railway maintenance department generally uses the method of installing the inner ring of corrugated plates by using scaffolding and pulleys. After the personnel arrive at the construction site, they first build a scaffolding platform, then install pulleys on the top of the tunnel, and then use the pulleys to hoist the corrugated plates to the designated position and fix them by the construction personnel. A set of inner ring of corrugated plates is composed of five independent corrugated plates, each weighing about 300 kg on average. In addition, there are power lines on the inner wall of the tunnel. In the process of hoisting the corrugated plates, the lines need to be avoided and installed in the gap between the lines and the tunnel lining arch. The labor intensity of manual installation is extremely large; at the same time, in the process of treating the subsidence disease of the line subgrade, pipes need to be pre-buried in the ballast by manual method. During construction, a person first digs a reverse conical pit at the corresponding position of the ballast using a shovel, then vertically places the prepared PVC pipe into the pit, then manually backfills the excavated ballast, and finally uses a handheld tamping machine to tamp the backfilled ballast. During this period, all the work of pipe burying is completed by manual work. The ballast is not easy to dig and may collapse at times, the construction efficiency is low, the labor intensity is large, and the buried pipes cannot be recycled, which may cause material waste. In addition, since the diseased railway line is still in normal operation, the disease treatment construction can only be carried out within a specified time, so the problem of low efficiency of manual construction is more prominent. SUMMARY

[0005] In order to solve the problems of low construction efficiency and large labor intensity of workers in the existing railway tunnel disease treatment, the present application provides a railway tunnel disease comprehensive treatment construction operation vehicle.

[0006] The present application is implemented by adopting the following technical scheme: a railway tunnel disease comprehensive treatment construction operation vehicle, comprising a track tractor with a construction equipment installation platform, a mechanical arm fixedly installed on the construction equipment installation platform for lifting corrugated plates to a designated position, a lifting platform for transporting a work personnel, and a pipe burying machine capable of being telescoped on both sides of the construction equipment installation platform and having an axial direction being vertical during use (as known to those skilled in the art, the pipe burying machine is one, and the pipe burying machine needs to be capable of being telescoped on the left side of the construction equipment installation platform and on the right side of the construction equipment installation platform, i.e. the front and back in the figure, and when the pipe burying machine is two, one is capable of being telescoped on the left side of the construction equipment installation platform, and the other is capable of being telescoped on the right side of the construction equipment installation platform, and how to be telescoped and how to make the axial direction be vertical during use are obtained by those skilled in the art through conventional means), the pipe burying machine comprising a motor, a linear drive pair for driving the motor to move linearly along the axial direction of the motor, and a spiral pipe assembly, the spiral pipe assembly comprising an inner shaft and a pre-buried spiral pipe, the inner shaft comprising a solid cone body with a tapered portion downward and a column body coaxially fixed to the top of the solid cone body, the circumferential surface of the column body being provided with external splines, the pre-buried spiral pipe comprising a hollow body adapted to the solid cone body of the inner shaft (the adaptation means that when the pre-buried spiral pipe is sleeved on the inner shaft upward from the bottom end of the inner shaft during use, the inner tapered surface of the hollow body of the pre-buried spiral pipe is fitted and fixed to the outer tapered surface of the solid cone body of the inner shaft, which is equivalent to the interference fit between the hollow body and the solid cone body) and a cylinder body fixedly connected to the top of the hollow body and adapted to the column body, the inner splines being provided on the inner circumferential surface of the cylinder body and adapted to the external splines, and the spiral blades being fixedly sleeved on the outer circumferential surface of the cylinder body, and the output shaft of the motor is fixedly connected to the top end of the column body.

[0007] The track tractor reaches the construction site flexibly under the traction of its own power according to the instructions of the railway maintenance department. The track tractor has three working states: 1) when the track tractor is dispatched between construction sites, all construction equipment is withdrawn to the construction equipment installation platform; 2) when the tunnel lining arch cracking disease treatment is performed to install the corrugated plate inner ring, the mechanical arm lifts the corrugated plate to the designated position, the lifting platform transports the work personnel to the corresponding position, and then the work personnel fix the corrugated plate; 3) when the line subgrade settlement disease treatment is performed to bury the pipe material in the ballast bed, the mechanical arm and the lifting platform are withdrawn to the construction equipment installation platform, the pipe burying machine is extended to both sides of the construction equipment installation platform (when the pipe burying machine is one, it is first extended to one side, and after the pipe material is buried at the corresponding position, the pipe burying machine is extended to the other side; when the pipe burying machine is two, it can be simultaneously extended to both sides of the construction installation platform, and then the pipe material can be buried at the corresponding positions on both sides), and the axial direction of the pipe burying machine is vertical, the pipe burying machine is operated to bury the pipe material in the ballast bed, and after the pipe material is buried on both sides of the construction equipment installation platform, the track tractor is moved forward to continue to bury the pipe material at the next position.

[0009] The beneficial effects produced by the present application are as follows: the application of the railway tunnel disease comprehensive treatment operation vehicle described in the present application in the actual construction process will completely change the current over-reliance on manual status, greatly improve the mechanization level of the construction of the pre-buried pipe in the ballast in the process of installing the inner ring of the corrugated plate in the process of treating the cracking disease of the tunnel lining arch and in the process of treating the subsidence disease of the line roadbed, and achieve the purposes of improving the construction efficiency and reducing the labor intensity; meanwhile, after the subsequent punching and grouting work on the roadbed is completed, the same set of devices can be used to recycle the pipe for repeated use, reducing material waste.
