Description

Technical Field

[0001] The present application relates to the field of railway maintenance and repair, and in particular to a rail collection and replacement operation system and operation method. 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] As the transportation density of existing lines becomes higher and higher, the required window operation time is becoming more and more limited. We urgently need a flexible track changing equipment and construction method.

[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, an embodiment of the present application provides a rail collecting and changing operation system and operation method.

[0009] 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.

[0010] According to a second aspect of an embodiment of the present application, a rail collecting and changing method is provided, comprising the following specific steps:

[0011] The front trolley carries the new track and guides it into the target installation position;

[0012] The rear trolley carries the old rail and guides the old rail to be replaced to the track center or ballast shoulder;

[0013] The rear trolley carries the old rail and transfers it to the front trolley;

[0014] The front trolley carries the old rails and transports them to external equipment.

[0015] The rail collecting and changing operation system and operation method provided in the embodiments of the present application have the following beneficial effects:

[0016] The technical solution provided in the embodiment of the present application can flexibly carry out track replacement and recycling operations according to actual conditions, make full use of the window time, realize the mechanization of track replacement, reduce the working pressure of construction personnel, and improve construction efficiency; the front trolley directly guides the new track into the target installation position, and the old track can be guided to both the center of the track and the ballast shoulder, which can effectively prevent the new and old tracks from interfering with each other.

[0046] As an embodiment of the present application, the front trolley 100 is connected to the rear trolley 200 by a steel wire rope, and a power system and a brake system are installed on the front trolley 100, making it easy to control travel and braking. In other embodiments, the front trolley 100 and the rear trolley 200 can also be connected by a cable, a chain or a connecting rod.

[0047] like Figure 4-Figure 6 As an embodiment of the present application, two sets of new rail guide devices 120 are installed at intervals at the front end of the front trolley 100, and the new rail guide device 120 includes a new rail guide frame 121, and the new rail guide frame 121 is used to carry the new rail 400 and guide the new rail 400 into the sleeper supporting rail groove.

[0050] In the embodiment of the present application, the mechanism for limiting and guiding the new track 400 above the new track guide frame 121 is reversible, which facilitates loading the new track 400 during the track replacement operation. A first limiting guide wheel 126 is installed on the upper end of the new track guide frame 121. The first limiting guide wheel 126 is a guide wheel with a wheel flange, which facilitates the limiting and guiding of the new track 400.

[0053] like Figure 4-Figure 7On the side close to the entrance of the new rail guide frame 121, a new rail guide inclined groove 128 and a first guide wheel 129 for limiting the position of the track are arranged. The first guide wheel 129 adopts a flangeless guide wheel to facilitate carrying and guiding the new rail 400. On the side close to the exit of the new rail guide frame 121, a second limiting guide wheel 1210 with a flange is arranged to limit the position of the new rail 400.

[0056] During implementation, the new track 400 can be placed in advance on the line where the track is to be replaced, or it can be transported to the site by a rail transport vehicle and used in conjunction with the rail collection and replacement operation system. The rail transport vehicle can load more than two tracks. After replacing the track of a section, it can be directly towed by a tractor to the next replacement point for track replacement, or towed to a station line near the replacement point to wait for the operation window point, thereby achieving maximum efficiency of the working time of the operating train and saving a lot of construction time.

[0090] In this embodiment of the present application, before the front trolley 100 carries the new track 400 and guides the new track 400 to the target installation position, the following steps are included:

[0091] (1) Before the track replacement operation, the fasteners on the old track 300 of the construction section shall be removed by a working train or manually;

[0092] (2) The front trolley 100 and the rear trolley 200 are stored in the rail-changing train car and arrive at the construction line section with the working train. After arriving at the working position, the front trolley 100 and the rear trolley 200 are unloaded onto the old track 300 to be replaced, with the front trolley 100 and the rear trolley 200 in order from front to back.
