Description

Technical Field

[0001] This application relates to the technical field of rail transit maintenance, and particularly to a rail unloading vehicle and an operation method thereof. Background Art

[0002] Railway sleeper replacement is one of the main tasks in the mechanized maintenance of railway lines. China's rail transit system is gradually replacing short rails with long rails for rail replacement.

[0003] There are mainly two existing methods for the collection and unloading of long rails: one is the transverse collection and unloading of rails. The transverse collection and unloading of rails uses a lifting device installed on the rail transport vehicle to synchronously lift the rails from both sides of the train and laterally move the rails to achieve the collection and unloading of long rails. The other is the longitudinal collection and unloading of rails. The collection and unloading of rails is carried out by the cooperation of a rail unloading trolley and a hoisting device, or a collection and unloading device with a robotic arm is installed on the long rail transport vehicle for the collection and unloading of rails.

[0004] However, when using the transverse collection and unloading method for rail collection and unloading operations, it is greatly affected by the construction environment and line conditions, and it cannot well adapt to the narrow space of tunnels and small curve radii. For longitudinal collection and unloading of rails, a hoisting device is required to lift and lower the trolley; if a collection and unloading device with a robotic arm is installed on the long rail transport vehicle for the collection and unloading of rails, the collection and unloading device needs to move on the long rail transport vehicle; therefore, tracks for the operation of the collection and replacement rail device need to be arranged on the long rail transport vehicle, and a bridging device needs to be arranged between adjacent vehicles. However, the smoothness of the connection between the bridging device and the front and rear vehicles in small curve sections is poor, and there are safety hazards in the operation of the collection and replacement rail device on the long rail transport vehicle.

[0005] In view of this, the present application is specifically proposed. Summary of the Invention

[0006] In order to solve one of the above technical defects, a rail unloading vehicle and an operation method thereof are provided in the embodiments of the present application.

[0007] According to the first aspect of the embodiments of the present application, a rail unloading vehicle is provided, including:

[0011] The up-and-down track device has its front end installed on the vehicle frame, and its rear end can swing vertically relative to the vehicle frame. When the rear end of the up-and-down track device swings to contact the track, it is used to receive the rail and unload the rail to a preset position on the track. When the rear end of the up-and-down track device swings to be parallel to the vehicle frame, the up-and-down track device slides forward to a preset position above the vehicle frame.

[0012] According to the second aspect of the embodiments of the present application, a rail unloading operation method is provided, which is characterized in that the above-mentioned rail unloading operation vehicle is adopted, and it includes the following steps:

[0013] The rail dragging device clamps the rail and drags the rail longitudinally backward.

[0014] The rail conveying device receives the rail dragged by the rail dragging device and conveys the rail longitudinally backward.

[0015] The up-and-down track device swings to contact the rail, receives the rail and unloads the rail to a preset position on the track.

[0016] The rail unloading operation vehicle provided by the embodiments of the present application includes a rail conveying device, a rail dragging device and an up-and-down track device. The rail dragging device is used to clamp the rail and drag the rail longitudinally backward to the rail conveying device; the rail conveying device is used to receive the rail and convey the rail longitudinally; the front end of the up-and-down track device is installed on the vehicle frame, and the rear end can swing vertically relative to the vehicle frame.
