Rail collecting device and method of seamless track quick track switching operating vehicle

Abstract

The invention relates to a rail collecting device and a method of a seamless track quick track switching operating vehicle. The device comprises a group of at least five rail clamping devices which are arranged below a vehicle body at intervals along the travel direction of the vehicle body, wherein, each rail clamping device is provided with a positioning assembly with the same structure and at least comprises a rail clamping device I, a rail clamping device II, a rail clamping device III, a rail clamping device IV and a rail clamping device V which have the clamping assemblies with different structures; the rail clamping device I and the rail clamping device II are rolling rail clamping devices, and the rail clamping device III, the rail clamping device IV and the rail clamping device V are sliding clamping devices. The method thereof can change the combination of the rail clamping devices according to the used rail placing position. In the operation process, each rail clamping device clamps the rail by sections so as to effectively control acting force due to short rail switching distance as well as big displacement and deformation of a new rail and a used rail, thus realizing that the rail is switched within 50 meters.

Description

technical field [0001] The invention relates to a railway construction operation machine and an operation method, in particular to a rail retracting device and a rail retracting method for a fast rail-changing operation vehicle for replacing seamless lines. Background technique [0002] At present, in the prior art, it is often necessary to clamp the rails during railway construction operations, such as changing rails, laying rails, and changing sleepers. Under various operating conditions, railway construction machinery will have different impacts on the construction work due to the different clamping and supporting surfaces of the rail. Such as changing track operation, existing railway track changing method and machinery are multiple, as Chinese patent CN2263610Y, CN2871617, CN2510526Y, CN1152169C disclose different types of track changing machines suitable for different purposes, the tracks of its rails and the stressed conditions are all the same. It is not the same. T...

Problems solved by technology

In the prior art, large-scale rail changing machines, such as the overhaul trains produced by the Swiss matisa company, generally have to replace the sleepers at the same time as changing the rails, and cannot complete a single rail changing operation, resulting in huge construction costs, narrow scope of application, and low operating efficiency. It can only reach a speed of 1km / h, and its track changing operation can be carried out in nine vehicles, and the operation length can reach 200 meters. Skylight point) to complete the track change work, because usually the short-term high-efficiency track change construction such as skylight point track change is very different from the long-term outage construction on the line, and the track change operation is usually completed on the line within 50 meters. Usually there are only two working lengths of vehicles, so simple track changing equipment has to be used, requiring hundreds or even hundreds of relevant cooperating construction personnel, which has a low degree of automation and increases potential safety hazards

The rail retracting device of this simple rail changing machine usually only has two rail clamping devices, one is used to clamp and place the new rail into the rail support groove, and the other is used to clamp the old rail and remove it from the support rail. In the process of changing the rail, the work of placing the new rail in place is done manually, and because the number of rail clamping devices is small, the clamping points of the rail are too few, and the rail is not changed according to the rail. During the displacement process, different clamping methods will be set at different heights, different horizontal positions and other factors. The torsion of the new rail and the old rail has not been effectively controlled, which largely depends on the manual control of the construction personnel. About 90% of the fasteners are removed by manual removal. It is difficult for the new rail and the old rail of the load-bearing section to maintain an upright state, which is likely to cause safety accidents such as overturning and falling off of the rail-changing machine, which not only endangers the safety of construction personnel, but also cannot The task of changing tracks was completed on schedule, affecting the normal opening of the line

Therefore there are potential safety hazards in the rail retracting device and method for changing rails in the prior art, and need to be further improved
