Description

Technical Field

[0001] The present application relates to the field of railway maintenance and repair, and in particular to a rail collecting and replacing operation system and operation method with a lifting function. Background Art

[0002] In recent years, the increasing weight and speed of trains have led to wear and tear on track, necessitating track re-laying and replacement. Railroad seamless line track replacement involves laying track onto the existing line. This process not only replaces the damaged track but also completes the seamless connection.

[0003] Currently, there are two methods for track replacement on seamless lines: manual track replacement, which is labor-intensive and slow, with poor quality, low efficiency, and a low safety factor. The other method is to use a track replacement vehicle to assist in track replacement.

[0004] However, due to axle loads and vehicle structural design, existing technologies only allow for limited recovery of old track material, significantly limiting the daily track replacement mileage. Furthermore, existing track replacement equipment requires the new rails to be transported to both sides of the track before the track replacement begins. After the track replacement, manual labor or other equipment is required to recover the old rails placed in the center of the trackbed.

[0005] In summary, the current track-changing equipment has few integrated functions, poor adaptability to different lines, and requires the use of other lifting equipment for lifting, which leads to a complicated track-changing process and low track-changing efficiency.

[0006] In view of this, this application is hereby filed. Summary of the Invention

[0007] In order to solve one of the above-mentioned technical defects, the embodiments of the present application provide a rail collecting and changing operation system and operation method with a lifting function.

[0008] According to a first aspect of an embodiment of the present application, a rail collecting and changing system with a hoisting function is provided, comprising:

[0009] A front trolley, used to carry new rails and guide them to the target installation location, as well as to carry old rails and transport them to external equipment;

[0010] The new rail lifting device is installed on the front trolley and is used to lift the new rail to the front trolley;

[0011] The rear trolley is used to carry the old rail and guide the old rail to the track center or ballast shoulder, and to transport the old rail to the front trolley;

[0012] The old rail lifting device is installed on the rear trolley and is used to lift the old rail to the rear trolley.

[0013] According to a second aspect of an embodiment of the present application, a rail collecting and changing method with a hoisting function is provided, comprising the following specific steps:

[0014] The new rail lifting device lifts the new rail to the front trolley;

[0015] The front trolley carries the new track and guides it into the target installation position;

[0018] The old rail lifting device lifts the old rail to the rear trolley;

[0019] The rear trolley carries the old rail and transfers it to the front trolley;

[0020] The front trolley carries the old rails and transports them to external equipment.

[0021] The rail collecting and changing operation system and operation method with a hoisting function provided in the embodiments of the present application have the following beneficial effects:

[0022] The technical solution provided by the embodiment of the present application does not require other equipment to lift the track during the track collection and replacement operation stage, which can greatly improve the operation efficiency, reduce work intensity, and generally enhance the applicability of the track replacement operation vehicle; the present application can also cooperate with the track transport vehicle to realize the "unloading instead of replacement" of the track. The new track is transported from the operating vehicle train or to the line where the track to be replaced is transported in advance, and is directly introduced into the target installation position by the front trolley. When collecting the track, the vehicle travels in the opposite direction, and the rear trolley and the front trolley quickly recover the track. The track replacement construction method is simple.

Specifically, the old track guide device 220 is equipped with a second lateral adjustment assembly to adjust the old track guide frame 221 laterally. When the old track guide device 220 is extended outward, the old track 300 is guided to the ballast shoulder. When the old track guide device 220 is retracted to the center, the old track 300 is guided to the track center.

[0075] The old rail guide device 220 of the embodiment of the present application also includes a second limiting member 224 and a pair of third limiting guide wheels 225; the second limiting member 224 is installed at the upper end of the old rail guide frame 221 and is flippably connected to the frame of the old rail guide frame 221; a pair of third limiting guide wheels 225 are installed at the upper and lower ends of the old rail guide frame 221, one of which is connected to the side of the second limiting member 224 that is close to the old rail guide frame 221, and is used to guide the old rail 300 in the longitudinal direction and limit the old rail 300 from moving in the lateral direction and / or vertically.

[0089] The old rail lifting device 210 on the rear trolley 200 is arranged in a forward and reverse direction at intervals, and the lifting direction of the old rail 300 is adjusted according to the operation direction during track changing and track collection. In the lifting solution of the rear trolley 200, the old rail lifting drive member 212 can adopt a hydraulic cylinder, and the hydraulic cylinder is extended and retracted to drive the traction rope to achieve the lifting of the old rail; when changing the track, the old rail lifting device 210 of the rear trolley 200 lifts the old rail 300 to be replaced, and the old rail guide chute 226 extends to catch the old rail 300 to be replaced; when collecting the track, the old rail lifting device 210 of the rear trolley 200 lifts the old rail 300 to be recovered onto the rear trolley 200, facilitating the track changing and collecting operations and improving the efficiency of track collection and changing.
