Description

Technical Field

[0001] The present application relates to the technical field of railway line maintenance and repair, and in particular to a sleeper replacement vehicle and a sleeper replacement system. Background Art

[0002] At present, the sleeper replacement operations on old rail lines mainly use two methods: large sleeper replacement trains and simple sleeper replacement equipment composed of small excavators and multi-functional sleeper grabbing devices.

[0003] Large sleeper-changing trains use two sets of devices for laying new sleepers and recycling old sleepers, which increases the manufacturing cost and the length of the sleeper-changing equipment. Sleepers need to be frequently transported between the sleeper storage vehicle and the sleeper-changing vehicle. The entire operation line is relatively long, large in size, and difficult to park. It is suitable for track line operation areas that require a large number of old rails to be replaced. However, the operation takes a long time and is inflexible, so it is not suitable for a small number of old sleepers to be replaced.

[0004] The simple sleeper replacement equipment composed of a small excavator and a multifunctional sleeper grabbing device has a short operation line and high flexibility, but it can only replace old sleepers over a short distance at a time, and new and old sleepers need to be transported frequently, which has a very low operation efficiency. In addition, during the sleeper replacement process, the new sleepers need to be placed on both sides of the roadbed in the operation area, and the replaced old sleepers also need to be temporarily placed on both sides of the roadbed, and then the replaced old sleepers need to be uniformly recycled, which increases labor costs and safety hazards.

[0048] Frame 1;

[0049] Two bogies 2 are respectively arranged at two ends of the bottom of the frame 1;

[0050] A first longitudinal conveyor belt 3 is arranged above the frame 1 and is used to carry and transport new and old sleepers;

[0051] A mobile operation trolley 4 is arranged below the frame 1 and can move longitudinally along the frame 1 to clamp old pillows and lay new pillows;

[0052] The lifting conveyor 5 comprises a front lifting conveyor and a rear lifting conveyor respectively arranged at the front and rear ends of the frame 1, the front lifting conveyor and the rear lifting conveyor are respectively located at the positions docking with the front and rear ends of the first longitudinal conveyor belt 3, and are used to convey the recycled old pillows to the first longitudinal conveyor belt 3, and transfer the new pillows on the first longitudinal conveyor belt 3;

[0054] The sleeper replacement vehicle in the present application can accommodate a mobile work vehicle and a mobile lift below. The front mobile lift transfers the old sleepers that the mobile work vehicle clamps and places on the track to the front lift conveyor, and then transports the old sleepers to the front end of the first longitudinal conveyor belt (the first longitudinal conveyor belt rotates backward during this process); at the same time, the new sleepers stored on the rear end of the first longitudinal conveyor belt are transported to the track in turn through the rear lift conveyor and the rear mobile lift, so that the mobile work vehicle can clamp and lay them to the required position. The sleeper replacement vehicle provided in the present application has a simple structure and a reasonable design. It can simultaneously realize the cyclic operation of recycling old sleepers and laying new sleepers, and the sleeper replacement efficiency is relatively high. The first longitudinal conveyor belt is used to carry and transport old sleepers and new sleepers, with high space utilization, small size, easy parking and more flexible use, avoiding the complicated process of grabbing and replacing the new sleepers placed on both sides of the track, and then placing the replaced old sleepers on both sides of the track, and then centrally recycling the old sleepers in the prior art, which can further improve the working efficiency. The arrangement of two bogies at the bottom of the frame makes the structure of the entire sleeper replacement vehicle more stable and facilitates the separate maintenance of the sleeper replacement vehicle.

[0055] Furthermore, the second longitudinal conveyor belt 52 is extended toward one end close to the corresponding mobile elevator 6, so as to facilitate the clamping of the sleepers by the rear mobile elevator, and facilitate the second longitudinal conveyor belt of the front lifting conveyor to take over the old sleepers on the front mobile elevator, so that the transfer of sleepers between the second longitudinal conveyor belt and the mobile elevator is smoother, and there will be no problem of sleepers slipping, which is safer and the operation effect is more stable.

[0057] The lifting conveyor 5 comprises:

[0058] A guide frame 51 is provided on the vehicle frame 1;

[0059] A second longitudinal conveyor belt 52;

[0060] The movable frame 53 is connected to the second longitudinal conveyor belt 52, and is connected to the guide frame 51 through a first lifting drive component. The first lifting drive component drives the movable frame 53 to drive the second longitudinal conveyor belt 52 to move from top to bottom to the first working position A and the second working position B; the first working position A corresponds to the position of the first longitudinal conveyor belt 3, and the second working position B corresponds to the position of the corresponding mobile elevator 6.

[0061] In the present application, the first lifting drive component can drive the mobile frame to drive the second longitudinal conveyor belt to move to the first working position A and the second working position B respectively, so as to realize the sleeper transmission between the second longitudinal conveyor belt and the first longitudinal conveyor belt and the mobile lift. Since the stroke of each working position is fixed, it can be moved according to the cycle, which is flexible and convenient to use, does not require human intervention, saves manpower and cost, reduces the occurrence of failures, and has higher working efficiency; and there is no need to set up sensors and other detection components, which improves the stability of operation.

[0062] Figure 4 Side view of the front mobile lift provided for this application, Figure 5 The front view of the mobile lift provided for this application, such as Figure 4-Figure 5 As shown, Figure 4 The direction indicated by the middle arrow is the direction of sleeper lifting. Figure 5 The direction indicated by the middle arrow is the direction of the sleeper closing.

[0063] A first running track 7 is provided on the frame 1 at a position close to the mobile lift 6, and the first running track 7 is provided along the length direction of the frame 1;

[0064] The mobile lift 6 comprises:

[0065] A first running component 61, which is adapted to the first running track 7, so that the first running component 61 can drive the entire mobile lift 6 to move along the setting direction of the first running track 7;

[0066] The telescopic frame 62 is arranged below the first running component 61, and the telescopic frame 62 is provided with a second lifting driving component, and the second driving component drives the telescopic frame 62 to extend and retract in the vertical direction;

[0067] The sleeper gripper 63 is arranged below the telescopic frame 62 and is located on the side close to the corresponding lifting conveyor 5.

The folding parts can realize the automatic centering function of the sleepers, avoid the interference of the sleepers with other parts during the transportation process, and are more convenient and safe.

[0068] In the present application, since there is a distance difference between the lifting conveyor and the clamping part of the mobile working vehicle in the longitudinal and vertical directions, the mobile lifting device arranged between the two needs to realize the longitudinal and vertical transportation of the sleepers. The first running component can move along the running track, thereby driving the telescopic frame and the sleeper gripper to move longitudinally, and the telescopic frame can be telescoped vertically, so that the sleepers transported on the sleeper gripper can be adjusted vertically. The sleeper gripper is located on the side close to the corresponding lifting conveyor, which is convenient for clamping the old sleepers that the mobile working vehicle clamps and places on the track, and then directly placing the old sleepers on the second longitudinal conveyor belt of the front lifting conveyor; and it is convenient to directly clamp the new sleepers on the rear lifting conveyor, and then transport them to the track close to the mobile working vehicle. Interference with other components is avoided during the operation, which is more convenient. The travel of the telescopic frame at each working position is also fixed, so it can be moved in a cycle. It is flexible and convenient to use and does not require human intervention, saving manpower and costs, reducing the occurrence of failures, and improving working efficiency. There is no need to set up sensors and other detection components, which improves working stability.

[0069] Furthermore, the telescopic frame 62 includes: at least two support frames 621 which are sequentially sleeved from the outside to the inside;

[0071] Among the two adjacent support frames 621, lifting grooves are set on the inner sides of the support frame 621 located on the outer layer, and lifting protrusions are set on the outer sides of the support frame 621 located on the inner layer. The two lifting grooves are respectively matched with the two lifting protrusions, so that the support frame 621 located on the inner side is lifted and lowered along the setting direction of the lifting grooves on the support frame 621 located on the outer side.

[0072] The telescopic frame in the present application is formed by at least two supporting frames, wherein the number of supporting frames is determined by the displacement required to be adjusted in the vertical direction, and the practicability is high. The lifting slot and the lifting protrusion are adapted to make the lifting process smoother and the use effect better.

[0073] Furthermore, the second lifting drive component includes at least one steel wire rope, a motor winch arranged on the top of the outermost support frame 621 and a pulley arranged on the innermost support frame 621, and the number and position of the pulleys correspond one-to-one to the steel wire rope; one end of the steel wire rope is wound around the motor winch, and the other end of the steel wire rope is connected to the corresponding pulley.

[0076] A second running component 42 disposed above the driver's cab 41 is adapted to the first running track 7 so that the second running component 42 can drive the driver's cab 41 to move along the setting direction of the first running track 7;

[0077] The working arm 43 has one end connected to the driver's cab 41, and the other end thereof is provided with a clamping portion 431 and a scraper 432. The working arm 43 is provided with a working drive component, and the working end of the working drive component is respectively connected to the clamping portion 431 and the scraper 432, and the operating table is electrically connected to the working drive component.

[0079] In this application, the mobile work vehicle needs to complete the grabbing of old pillows and the laying of new pillows, so a driver's cab needs to be set up, and it needs to rotate through a slewing support part to reduce the visual blind spot. The work drive component makes the operation of the clamping part and the scraper more flexible, and the grabbing of old pillows and the laying of new pillows are more precise.
