Description

Technical Field

[0001] This application relates to the field of rail transit maintenance technology, and in particular to rail unloading vehicles. Background Technology

[0002] Replacing railway sleepers is one of the main tasks in the mechanized maintenance of railway lines. my country's rail transit system is gradually replacing short rails with longer ones.

[0003] There are two main methods for unloading and receiving long steel rails: one is transverse unloading, where a lifting device mounted on the rail transport vehicle simultaneously lifts the rails from both sides of the train and moves them laterally to unload the long rails. The other is longitudinal unloading, which involves using an unloading trolley in conjunction with a lifting device to unload the rails, or using a rail unloading device with a robotic arm mounted on the long rail transport vehicle.

[0004] However, using a transverse rail loading and unloading method is greatly affected by the construction environment and track conditions, and cannot be well adapted to the narrow space of tunnels and small curve radii. Using a longitudinal rail loading and unloading method requires a hoisting device to load and unload the trolley; if a rail loading and unloading device with a mechanical arm is used on a long rail transport vehicle, the device needs to move along the vehicle. Therefore, the long rail transport vehicle needs to be equipped with the track for the rail loading and unloading device, and a bridge device is required between adjacent vehicles. However, the bridge device has poor smoothness in connecting with vehicles on small curves, and there are safety hazards associated with the rail loading and unloading device operating on the long rail transport vehicle.

[0005] In view of the above, this application is hereby submitted. Summary of the Invention

[0006] To address one of the aforementioned technical deficiencies, this application provides a rail unloading vehicle in its embodiments.

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

[0008] Frame;

[0009] A rail dragging device, located above the chassis, is used to clamp the rails and drag them longitudinally backward.

[0010] The rail conveying device is located above the vehicle frame and is used to receive the rails towed by the rail towing device and to transport the rails longitudinally along the vehicle frame.

[0011] The upper and lower track device has its front end mounted on the vehicle frame and its rear end able to swing vertically relative to the vehicle frame. When the rear end of the upper and lower 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 upper and lower track device swings to be parallel to the vehicle frame, the upper and lower track device slides forward to a preset position above the vehicle frame.

[0012] The rail unloading vehicle provided in this application includes a rail conveying device, a rail dragging device, and a track loading / unloading device. The rail dragging device clamps the rail and drags it longitudinally backward to the rail conveying device. The rail conveying device receives the rail and transports it longitudinally. The front end of the track loading / unloading device is mounted on the chassis, and its rear end can swing vertically relative to the chassis. When the rear end of the track loading / unloading device swings to contact the track, it receives the rail and unloads it to a preset position on the track. The track loading / unloading device can be automatically deployed and retracted without the need for a dedicated running track, resulting in a simple structure and low manufacturing and maintenance costs.

[0040] The front end of the track-mounting device 2 is set on the frame 1, and the rear end can swing vertically relative to the frame 1. When the rear end of the track-mounting device 2 swings to contact the rail on the ground, it is used to receive the rail and unload the rail to the preset position on the rail. When the rear end of the track-mounting device 2 swings to be parallel to the frame 1, the track-mounting device 2 slides forward to the preset position above the frame 1.

[0041] In practice, during operation, when the rear end of the upper and lower track device 2 swings to contact the track on the ground, it is used to receive the rail and unload the rail to the preset position on the track. During retraction, when the rear end of the upper and lower track device 2 swings to be parallel to the frame 1, the upper and lower track device 2 slides forward to the preset position above the frame 1.

The structure is simple and the manufacturing and maintenance costs are low.

[0042] As an embodiment of this application, a rail unloading vehicle is provided, which also includes a track-mounting device drive device 5;

[0043] The track-mounting device drive device 5 is mounted on the frame 1 and is used to drive the track-mounting device 2 to retract onto the frame 1 and to lower the track-mounting device 2 to a preset position on the track.

[0044] In practice, the upper and lower track device 2 is provided with the power required for lowering and retracting through the upper and lower track device drive device 5.

[0045] It is worth noting that the drive device 5 for the upper and lower tracks can be implemented using a sprocket and chain mechanism, or it can be implemented using a mechanism in the existing technology that can drive the upper and lower tracks, so it will not be elaborated further.

[0046] The rail dragging device 4 can be implemented using a winch or other existing structures with dragging function, so it will not be described in detail.

The guide plate drive component 2314 provides the driving force for the guide plate 2313 to swing left and right relative to the horizontal plane, with the connection point with the swing beam 2312 as the pivot. In specific implementations, both the guide plate drive component 2314 and the swing beam drive component 2315 can be hydraulic cylinders, or other drive components or power structures capable of providing power. The guide plate drive 2314 and the swing beam drive 2315 adjust the position of the swing beam 2312 and the guide plate 2313 so that the center line of the guide channel 2316 located on the guide plate 2313 is parallel to the rail, so as to support the rail and enable the rail to be placed in a specified position or to be supported in a suitable position.
