Description

TECHNICAL FIELD

[0001] The present application relates to the field of replacing sleepers, in particular to a continuous sleeper replacement vehicle and a method for operating the same. BACKGROUND

[0002] A track is an integral engineering structure, mainly composed of rails, sleepers, connecting parts, ballast, anti-climbing equipment and switches, etc. The sleeper is the support of the rail, mainly bearing the pressure from the rail and transmitting it to the ballast, and also plays a role in maintaining the position and gauge of the rail. With the rapid development of high-speed and heavy-load railway lines, the service life of sleepers is shortened. In order to ensure the normal operation of the line, sleeper replacement is carried out. The seamless line has developed from the ordinary seamless line to the interval and cross-interval seamless line, and has become the main track structure of the railway line in China. For the seamless line, the sleeper replacement has higher requirements.

[0003] At present, the main sleeper replacement construction methods for domestic seamless lines are manual sleeper replacement, sleeper replacement excavator replacement and large-scale track maintenance machinery continuous sleeper replacement. Manual sleeper replacement generally uses the method of removing the ballast between sleepers for operation. During construction, the ballast in the sleeper box is removed and placed lower than the bottom surface of the sleeper, and then the single sleeper to be replaced is removed to the removed position. Manual sleeper replacement has the disadvantages of high labor input, high labor intensity, low sleeper replacement efficiency and high operation cost. Sleeper replacement excavator replacement mainly uses sleeper replacement excavator replacement, and the sleeper replacement method is also single sleeper replacement. The sleeper replacement excavator is a small excavator combined with a multifunctional sleeper grabbing device. It has the problems of multiple operation points and difficult construction organization. Large-scale track maintenance machinery continuous sleeper replacement mainly introduces a large-scale maintenance train. The large-scale maintenance train can replace the rail and sleeper simultaneously, or replace the rail or sleeper separately. However, it still has certain limitations, such as more participants, large coordination workload, low operation efficiency and damage to the integrity of the seamless line due to track cutting operation.

[0049] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the following further describes the exemplary embodiments of the present application with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0050] In this application, the length direction of the work vehicle is defined as longitudinal, the width direction of the work vehicle as transverse, and the height direction of the work vehicle as vertical.

[0051] In the process of developing this application, the inventors discovered that providing a work vehicle that does not require cutting the rails, has high work efficiency, and can be applied to different types of rail sleeper replacement operations is a problem that urgently needs to be solved.

[0052] Figure 1 This is a structural schematic diagram of a continuous sleeper replacement vehicle provided in an embodiment of this application, as shown below. Figure 1 As shown, in order to address the above-mentioned problems, this application provides a continuous sleeper replacement vehicle, including: a vehicle frame 1, at least two rail lifting devices 2 are connected at intervals along the length of the vehicle frame 1, the rail lifting devices 2 lift the rails below the vehicle frame 1; the vehicle frame 1 is also provided with an old sleeper picking device 3 and a new sleeper laying device 4 in sequence, the old sleeper picking device 3 clamps and retrieves the old sleepers below the vehicle frame 1, and the new sleeper laying device 4 lays the new sleepers at the original position of the old sleepers below the vehicle frame 1.

[0053] The continuous sleeper replacement vehicle provided in this application embodiment has good adaptability and can adapt to sleeper replacement operations for different types of tracks. Before sleeper replacement, there is no need to cut the rails; the rails under the vehicle are simply lifted by a rail lifting device. This does not change the rail spacing, does not damage the integrity of the seamless track, and does not affect the operation accuracy due to the curvature of the railway line. It can maintain the original track's curve or straight direction and does not change the original sleeper spacing. It can simultaneously and continuously pick up old sleepers and lay new sleepers, resulting in high operation efficiency. It does not require a large number of manual laborers for operation, effectively saving costs.

[0054] The work vehicle frame 1 is also equipped with an old sleeper recycling assembly 5, used to receive old sleepers held by the old sleeper clamping assembly 31; the old sleeper recycling assembly 5 includes a longitudinally arranged recycling rack 51, on which a first longitudinal conveyor belt is laid. The work vehicle frame 1 is also equipped with a new sleeper storage assembly 6, used for conveying and storing new sleepers; the new sleeper storage assembly 6 includes a longitudinally arranged storage rack 61, on which a third longitudinal conveyor belt is laid. The configuration of the old sleeper recycling assembly and the new sleeper storage assembly makes it easier to systematically recycle old sleepers during sleeper replacement and to retrieve new sleepers during the laying process. Specifically, the first longitudinal conveyor belt and the third longitudinal conveyor belt can be any of the following: belt conveyor, chain conveyor, or roller conveyor.

[0055] Figure 2 This is a schematic diagram of the structure of the rail lifting device provided in the embodiments of this application; Figure 3 This is a schematic diagram of the rail clamping assembly provided in the embodiments of this application; as shown below.Figure 2 and Figure 3 As shown, the rail lifting device 2 further includes a crossbar 21. Both ends of the crossbar 21 are connected to the work vehicle frame 1 via a first lifting component 22. Two rail clamping assemblies 23 are spaced apart in the middle of the crossbar 21, clamping the two rails respectively. Each rail clamping assembly 23 includes a connecting pipe 231 sleeved on the crossbar 21. Two clamping members 232 are hinged to the lower part of the connecting pipe 231, and the middle of the two clamping members 232 is connected via a clamping cylinder. In the non-operating state, the first lifting component raises the rail lifting device to the traveling position, allowing it to travel with the work vehicle. In the operating state, the first lifting component lowers the rail clamping assembly to a position where the clamping end of the rail clamping assembly aligns with the top of the rail. Then, the clamping cylinder tightens the clamping ends of the two clamping parts, thereby clamping the top of the rail. The rail lifting device clamps and lifts the rails in the working area, raising the rails and spikes to a height where the sleepers can move flexibly. The spikes are lifted to a greater height than the rails. Specifically, a first lateral movement component connects the connecting pipe 231 and the crossbar 21. By adjusting the first lateral movement component, the rail clamping assembly is adjusted laterally relative to the crossbar, thereby aligning the two clamping parts vertically with the two rails respectively.

[0056] At least three rail lifting devices 2 are sequentially installed along the extension direction of the rails, each lifting two rails. Figure 1 In the direction of operation, one rail lifting device 2 is located at the front end of the old sleeper picking device 3, one rail lifting device 2 is located at the rear end of the new sleeper laying device 4, and another rail lifting device 2 is located between the old sleeper picking device 3 and the new sleeper laying device 4.

[0057] Along Figure 1 In the direction of operation, the rail clamping assembly 23 in the rail lifting device 2 located at the front and middle of the work vehicle can move laterally to increase the distance between the two rails, facilitating rail replacement. The rail clamping assembly 23 in the rail lifting device 2 located at the rear of the work vehicle can move laterally so that the rail is exactly above the rail bearing groove of the sleeper, so that the rear rail naturally falls into the rail bearing groove during the movement of the work vehicle, realizing continuous operation without stopping.

The clamping component clamps the old sleeper on the ballast bed, then rotates the clamped old sleeper through the rotating assembly by a certain angle, so that the old sleeper can smoothly pass through the steel rail, when the old sleeper is lifted above the steel rail by the second lifting component, the rotating assembly rotates the old sleeper to the transverse direction, and then the old sleeper is collected.

In the working state, when braking is needed, the third lifting oil cylinder drives the brake component to descend to a position where the clamping plate is adapted to the top of the rail, and then the two clamping plates are tightened through the adjusting oil cylinder to clamp the top of the rail, so that the braking is realized. When the braking is not needed, the third lifting oil cylinder lifts the brake component to the walking position, and walks together with the working vehicle.
