Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway sleeper maintenance technology, and more specifically, to a railway sleeper maintenance device. Background Technology
[0002] As supports for the rails, railway sleepers play a crucial role in supporting and securing them. They bear the vertical, lateral, and longitudinal horizontal forces from the rails and distribute these forces evenly across the track bed. As a vital component of railway lines, the quality and performance of sleepers directly impact the overall quality of the railway. Through maintenance, the integrity and stability of sleepers can be ensured, thereby improving the quality of the railway line and guaranteeing the safe and smooth operation of trains.
[0003] Railway sleepers often require moisture retention during the production process to prevent excessive evaporation of moisture from the concrete surface, which could lead to shrinkage cracks inside the concrete. However, in traditional techniques, sleeper maintenance often requires manual watering by workers, which is time-consuming and labor-intensive. Some methods involve fixed-point watering, which is costly and ineffective, resulting in a waste of water resources. Therefore, it is necessary to improve and optimize a sleeper maintenance device. Utility Model Content
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a sleeper maintenance device, which has the advantages of reducing the cost of manual watering, increasing the water spraying range, and avoiding the waste of water resources.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sleeper maintenance device, comprising two crossbeams. A motor is fixedly connected to the upper surface of the front crossbeam, and a first gear is fixedly connected to the output of the motor. A first fixing block is fixedly connected to the upper surface of the middle part of the front crossbeam. A threaded rod is threadedly connected to the inside of the first fixing block, and a moving block is threadedly connected to the middle surface of the threaded rod. A rotating water spray structure is provided inside the moving block. A third gear is fixedly connected to the front surface of the threaded rod, and the third gear meshes with the first gear. A pipe moving structure is provided on the upper surface of the first fixing block.
[0006] As a preferred technical solution of this utility model: the rotating water spray structure includes a fixed joint fixedly connected inside the moving block, an elbow rotatably connected to the lower part of the fixed joint, a nozzle fixedly connected to one side surface of the elbow, a second gear fixedly connected to the middle surface of the elbow, a connecting block fixedly connected to the inner side of the first fixed block, a rack fixedly connected to the inner side of the connecting block, and the rack and the second gear meshing with each other.
[0007] As a preferred technical solution of this utility model: the pipe moving structure includes a rubber tube fixedly connected to the upper surface of the fixed joint, a second fixed block is fixedly connected to the upper surface of the first fixed block, a fixed rod is fixedly connected to the inner surface of the second fixed block, and a plurality of hanging rings are movably connected to the surface of the fixed rod, with the lower part of the hanging rings fixedly connected to the middle part of the rubber tube.
[0008] As a preferred technical solution of this utility model: a plastic tube is fixedly connected to the rear surface of the second fixing block at the rear, a third fixing block is fixedly connected to the middle of the plastic tube, the front surface of the third fixing block is fixedly connected to the rear surface of the rear crossbeam, and a water supply system is fixedly connected to the lower part of the plastic tube.
[0009] As a preferred technical solution of this utility model: a guide rod is connected to the inner valley bottom of the first fixed block, the guide rod is movably connected to the interior of the moving block, and the surface of the guide rod is fixedly connected to the interior of the connecting block.
[0010] As a preferred technical solution of this utility model: a rubber sealing ring is fixedly connected inside the fixed joint, and the rubber sealing ring is located below the upper part of the elbow.
[0011] As a preferred embodiment of this utility model: supports are fixedly connected to both sides of the crossbeam, longitudinal beams are fixedly connected to the front and rear inner sides of the supports, and a U-shaped base is fixedly connected to the lower surface of the supports.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model utilizes the rotation of the motor output shaft to drive the rotation of the first gear. Simultaneously, the meshing of the gears drives the rotation of the threaded rod. Since the surface of the threaded rod is threadedly connected to the moving block, the water spray structure achieves a mobile water spraying function. Furthermore, the auxiliary effect of the moving pipe structure enhances the stability of sleeper maintenance. This device reduces the cost of manual watering, increases the spraying range, and avoids the poor maintenance effect of fixed-point water spraying, thus preventing water waste.
[0014] 2. This utility model uses a moving block to drive the fixed joint to move while the moving block moves. The elbow is located inside the fixed joint and rotates. The force for the elbow's rotation is provided by the resistance of the meshing of the rack and the second gear. The rotational speed of the elbow is determined by the ratio of the teeth on the elbow surface to the teeth of the rack and the speed of the motor. This device controls the rotation of the elbow through the meshing of the gears. Because the elbow is curved, the nozzle can spray water more widely, which is more conducive to the maintenance of the sleepers and reduces the cost of using multiple sets of nozzles.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1 to 5 As shown, this utility model provides a sleeper maintenance device, including a crossbeam 1, the number of crossbeams 1 is two, a motor 2 is fixedly connected to the upper surface of the front crossbeam 1, a first gear 3 is fixedly connected to the output of the motor 2, a first fixing block 4 is fixedly connected to the middle upper surface of the front crossbeam 1, a threaded rod 5 is threadedly connected inside the first fixing block 4, a moving block 6 is threadedly connected to the middle surface of the threaded rod 5, a rotating water spray structure is provided inside the moving block 6, a third gear 25 is fixedly connected to the front surface of the threaded rod 5, the third gear 25 meshes with the first gear 3, and a pipe moving structure is provided on the upper surface of the first fixing block 4.
[0023] Workers neatly stack the mass-produced sleepers inside the U-shaped base frame 24. At this time, the motor 2 is started. The rotation of the output shaft of the motor 2 drives the rotation of the first gear 3. At the same time, the first gear 3 meshes with the third gear 25, thereby driving the rotation of the third gear 25. Since the third gear 25 is fixedly connected to the threaded rod 5, the threaded rod 5 is rotated inside the first fixed block 4. The guide rod 19 limits the movement of the moving block 6. Since the moving block 6 is threadedly connected to the threaded rod 5, the moving block 6 moves back and forth, so that the water spray structure fixedly connected inside the moving block 6 sprays water onto the sleepers. Due to the design of the pipeline moving structure, the stability of the spray is ensured.
[0024] The rotating water spray structure includes a fixed joint 7 fixedly connected inside the movable block 6, an elbow 8 rotatably connected to the lower part of the fixed joint 7, a nozzle 9 fixedly connected to one side surface of the elbow 8, a second gear 10 fixedly connected to the middle surface of the elbow 8, a connecting block 11 fixedly connected to the inner side of the first fixed block 4, a rack 12 fixedly connected to the inner side of the connecting block 11, and the rack 12 meshes with the second gear 10.
[0025] When the movable block 6 moves, it is fixedly connected to the fixed joint 7, thereby driving the fixed joint 7 to move. At the same time, the elbow 8 is rotatably connected to the fixed joint 7, and the connecting block 11 provides the mounting point for the rack 12. The rack 12 fixedly connected to the inner surface of the connecting block 11 meshes with the second gear 10 fixedly connected to the surface of the elbow 8, so that the fixed joint 7 drives the nozzle 9 to rotate while moving, thereby achieving a wider water spray.
[0026] The pipeline moving structure includes a rubber tube 13 fixedly connected to the upper surface of the fixed joint 7, a second fixed block 14 fixedly connected to the upper surface of the first fixed block 4, a fixed rod 15 fixedly connected to the inner surface of the second fixed block 14, and a plurality of hanging rings 16 movably connected to the surface of the fixed rod 15. The lower part of the hanging rings 16 is fixedly connected to the middle part of the rubber tube 13.
[0027] The movement of the moving block 6 drives the movement of the fixed joint 7, and the upper part of the fixed joint 7 drives the rubber tube 13 to move. However, the rubber tube 13 is fixed to the lower part of the hanging ring 16 by the cable tie, so that the hanging ring 16 can slide along the surface of the fixed rod 15, thereby preventing the rubber tube 13 from forming a single "U" shape due to gravity, thus increasing the burden on the water supply system 18.
[0028] Among them, a plastic pipe 17 is fixedly connected to the rear surface of the second fixing block 14 at the rear, a third fixing block 20 is fixedly connected to the middle of the plastic pipe 17, the front surface of the third fixing block 20 is fixedly connected to the rear surface of the rear crossbeam 1, and a water supply system 18 is fixedly connected to the lower part of the plastic pipe 17.
[0029] Water is supplied to the inside of the rubber tube 13 through the plastic tube 17. The third fixing block 20 fixes the position of the plastic tube 17. The water supply system 18 is a simple water supply system containing a water pump and a water tank, which supplies water to the nozzle 9 to spray the sleepers for maintenance.
[0030] The first fixed block 4 has a guide rod 19 connected to the inner valley bottom. The guide rod 19 is movably connected to the interior of the movable block 6, and the surface of the guide rod 19 is fixedly connected to the interior of the connecting block 11.
[0031] The guide rod 19 limits the position of the moving block 6, ensuring that the moving block 6 can only move back and forth. The guide rod 19 is fixedly connected to the moving block 6 to prevent the moving block 6 from moving too far backward, thereby squeezing the rubber tube 13.
[0032] Among them, the fixed joint 7 is internally fixedly connected with a rubber sealing ring 21, which is located below the upper part of the elbow 8.
[0033] The design of the rubber sealing ring 21 seals the rotating connection between the elbow 8 and the fixed joint 7, preventing water from flowing out from the connection.
[0034] Among them, the two sides of the crossbeam 1 are fixedly connected to the bracket 22, the front and rear inner sides of the bracket 22 are fixedly connected to the longitudinal beam 23, and the lower surface of the bracket 22 is fixedly connected to the U-shaped base frame 24.
[0035] The bracket 22 provides the mounting points for the crossbeam 1, while the longitudinal beam 23 is used to connect the bracket 22. The design of the U-shaped base frame 24 allows workers to use a forklift to transport the sleeper from the front of the U-shaped base frame 24 to the inside of the U-shaped base frame 24.
[0036] Working principle and usage process of this utility model:
[0037] Workers neatly stack the mass-produced sleepers inside the U-shaped base frame 24. At this time, the motor 2 is started. The rotation of the output shaft of the motor 2 drives the rotation of the first gear 3. At the same time, the first gear 3 meshes with the third gear 25, thereby driving the rotation of the third gear 25. Since the third gear 25 is fixedly connected to the threaded rod 5, the threaded rod 5 is rotated inside the first fixed block 4. The guide rod 19 limits the movement of the moving block 6. Since the moving block 6 is threadedly connected to the threaded rod 5, the moving block 6 moves back and forth, so that the water spray structure fixedly connected inside the moving block 6 sprays water onto the sleepers. Due to the design of the pipeline moving structure, the stability of the spray is ensured.
[0038] When the movable block 6 moves, it is fixedly connected to the fixed joint 7, thereby driving the fixed joint 7 to move. At the same time, the elbow 8 is rotatably connected to the fixed joint 7, and the connecting block 11 provides the mounting point for the rack 12. The rack 12 fixedly connected to the inner surface of the connecting block 11 meshes with the second gear 10 fixedly connected to the surface of the elbow 8, so that the fixed joint 7 drives the nozzle 9 to rotate while moving, thereby achieving a wider water spray.
[0039] The movement of the moving block 6 drives the movement of the fixed joint 7, and the upper part of the fixed joint 7 drives the rubber tube 13 to move. However, the rubber tube 13 is fixed to the lower part of the hanging ring 16 by the cable tie, so that the hanging ring 16 can slide along the surface of the fixed rod 15, thereby preventing the rubber tube 13 from forming a single "U" shape due to gravity, thus increasing the burden on the water supply system 18.
[0040] Water is supplied to the inside of the rubber tube 13 through the plastic tube 17. The third fixing block 20 fixes the position of the plastic tube 17. The water supply system 18 is a simple water supply system containing a water pump and a water tank, which supplies water to the nozzle 9 to spray the sleepers for maintenance.
[0041] The guide rod 19 limits the position of the moving block 6, ensuring that the moving block 6 can only move back and forth. The guide rod 19 is fixedly connected to the moving block 6 to prevent the moving block 6 from moving too far backward, thereby squeezing the rubber tube 13.
[0042] The design of the rubber sealing ring 21 seals the rotating connection between the elbow 8 and the fixed joint 7, preventing water from flowing out from the connection.
[0043] The bracket 22 provides the mounting points for the crossbeam 1, while the longitudinal beam 23 is used to connect the bracket 22. The design of the U-shaped base frame 24 allows workers to use a forklift to transport the sleeper from the front of the U-shaped base frame 24 to the inside of the U-shaped base frame 24.
