Technical Field
[0001] The utility model relates to the technical field of track operation, in particular to a track gravel laying and cleaning device. Background Art
[0002] In life, one of the essential ways to travel is high-speed rail or train, and this method inevitably uses rails. The rails are doubled to form a track, and the train or high-speed rail runs on the track to take us on a trip.
[0003] In order to reduce noise, drain water, protect the roadbed, speed up heat dissipation and other purposes, gravel is laid on the track. Therefore, in the process of track laying, laying gravel is also a necessary operation. After the track is laid, the gravel will inevitably change its position under the action of vibration over time. For example, the splashing gravel will pile up between the tracks, or the gravel on both sides of the track will get closer and closer to the rails. These situations will increase the safety risk of train operation, and workers will need to regularly re-lay or clean these gravel. The existing operations are basically performed by railway workers using tools along the rails manually. This method requires a lot of time and physical strength of workers, and it is easy to be inefficient, affecting the operation of trains. Utility Model Content
[0004] The purpose of the utility model is to provide a track gravel laying and cleaning device to solve the above-mentioned deficiencies in the prior art.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A track gravel laying and cleaning device comprises a main push plate and a linkage mechanism, wherein the main push plate is arranged at one side of the linkage mechanism, and the linkage mechanism is used to connect with a power tractor, and the linkage mechanism is driven by the power of the power tractor to push or pull the main push plate along the track to achieve the purpose of cleaning or laying track gravel, the main push plate is integrally formed by two groups of arc plates and a shovel arc plate is arranged in the middle of the bottom, and the gravel on the inner side of the track is flattened by the shovel arc plate when working on the track, and rail covers are respectively arranged on both sides of the shovel arc plate, and the side edges of the rail covers adjacent to the shovel arc plate are smoothly connected to the shovel arc plate, and the rail covers are arranged when working. The shovel plate is provided with an outer side of the corresponding track to prevent stones from splashing and hitting the rails, thereby protecting the track and guiding the stones when cleaning the stones. When the shovel plate pushes and shovels the stones on the inner side of the track and there are too many stones accumulated in front of it, they will overflow to the outside of the track along the outer side of the rail cover, thereby cleaning the excess stones. Action plates are hinged on both ends of the main push plate, and the angle between the action plate and the main push plate can be adjusted. When the excess stones on the inner side of the track overflow to the outer side of the track, the action plates at both ends of the main push plate will guide them again. The larger the angle between the action plate and the inner side of the main push plate, the better the stone cleaning effect. The farther the guide position is from the track, the more the distance between the excess stones and the track can be adjusted when cleaning the stones, which increases the practicality. A number of reinforcing plates are fixedly arranged on the inner side of the main push plate to increase the rigidity of the main push plate. Two sets of fixed welding plates are fixedly connected to one side of the reinforcing plate. The fixed welding plate is connected to a linkage mechanism. One side of the linkage mechanism is connected to the fixed welding plate in a hinged manner and the other side is connected to a power tractor. The horizontal angle of the main push plate can be fine-tuned through the linkage mechanism, and then the depth of the shovel arc plate for cleaning stones can be adjusted, and at the same time, it can adapt to different slopes of the track, thereby increasing the use The effect is that when working on the track, the linkage mechanism is connected to the power traction vehicle, and the power traction vehicle controls the rail covers of the main push plate to be erected above the track respectively, and then the horizontal height and angle of the main push plate are adjusted by the linkage mechanism according to the terrain or the slope of the track, and finally the power traction vehicle pushes the main push plate along the track, and the arc shovel plate in the main push plate is used to push or flatten and clean the gravel on the inner side of the track, and the action plates on both sides can adjust the distance between the cleaned gravel and the track, thereby achieving the purpose of automated cleaning and laying of gravel on the track, abandoning the manual cleaning and laying of gravel, which can save manpower and increase efficiency.
[0007] Furthermore, a longitudinal axis is provided on one side of the action plate, and a plurality of sleeves are sleeved on the outer side of the longitudinal axis. One side of the sleeves is fixedly connected to the side of the main push plate. Two groups of connecting blocks are fixedly provided on the adjacent side of the action plate and the main push plate. One end of the connecting block is fixedly connected to the corresponding longitudinal axis. The longitudinal axis, sleeve and connecting block cooperate to form a hinge, so that the action plate can freely change the angle between it and the main push plate.
[0008] Furthermore, two layers of adjustment plates are fixed to the inner edge of the main push plate, and the two layers of adjustment plates are provided with corresponding plug-in holes, and an adjustment rod is provided between the two layers of adjustment plates. One end of the adjustment rod is hinged to the inner side of the corresponding action plate, and the other end is arranged between the two layers of adjustment plates and is fixed by bolts through the plug-in holes. After the action plate adjusts the angle with the main push plate, the position of the action plate is limited by fixing the adjustment rod and the adjustment plate with bolts, thereby ensuring stability during operation.
[0009] Furthermore, the linkage mechanism includes a traction frame, a positioning plate, a fine-adjustment plate, and a hydraulic cylinder. The traction frame is connected to a traction vehicle that provides power drive. A positioning plate is provided at one end of the traction frame, and a hydraulic cylinder is provided on one side of the positioning plate. The bottom output end is hinged to the side of the fine-adjustment plate. Extension plates are provided at both ends of the fine-adjustment plate, and the extension plates correspond to the fixed welding plates respectively. Main hinge shafts are provided at the top and bottom of the fixed welding plate, and the extension plates are respectively hinged to the fixed welding plate through the main hinge shafts at the bottom of the fixed welding plate to realize the connection between the main pushing plate and the linkage mechanism. The other side of the fine-adjustment plate is hinged to the bottom of the positioning plate. One end of an intermediate rod is fixedly provided at both ends of the bottom of the positioning plate, and the other end of the intermediate rod is hinged to one side of the traction frame. A fixed connecting plate is provided at the top of the positioning plate, and the fixed connecting plate is fixedly connected to the top of the hydraulic cylinder. The fixed connecting plate realizes the fixed placement of the hydraulic cylinder. One end of a hinge connecting rod is hinged at each end of the top of the positioning plate, and the other end of the hinge connecting rod is respectively hinged through the fixed welding plate The main hinge shaft at the top is hinged with the fixed welding plate, and the hinge connecting rod further increases the stability of the hinge connection between the linkage mechanism and the main push plate. When the height of the main push plate shovel needs to be adjusted, it can be achieved by the staff operating the hydraulic cylinder. Because the output end of the hydraulic cylinder bottom is hinged with the edge of one side of the fine-tuning plate, and because the two ends of the fine-tuning plate are hinged with the two sides of the bottom of the positioning plate, the hydraulic cylinder will drive the fine-tuning plate to flip with the hinge position of the positioning plate as the axis when it works. When the side of the fine-tuning plate flips downward, it will drive the extension rod to apply a downward pressure on the fixed welding plate. According to the principle that the positioning plate, hinge connecting rod, fixed welding plate, and extension rod on the same side form a parallelogram frame hinged at the head and tail, one end of the extension rod moves downward, which will drive the fixed welding plate to move downward, and then drive the main push plate to move downward. Similarly, it can also drive the main push plate to move upward, so as to achieve the adjustment of the height of the main push plate shovel, which is convenient for the device to programmably control the height of subway track gravel paving or cleaning, thereby improving practicality.

Because the bottom of the positioning plate is hinged to one side of the traction frame through the intermediate rod, the screw will push or pull the positioning plate to flip and tilt with the intermediate rod and the traction frame hinge position as the axis, thereby driving the main push plate to tilt and flip as a whole, thereby changing the angle between the shoveling arc plate and the horizontal ground, thereby controlling the shoveling depth, further improving practicality.
[0011] Furthermore, a functional hole with a thread is provided on one side of the screw sleeve. After the screw is adjusted by the screw sleeve to make the main push plate tilt to a suitable angle, the screw can be screwed into the functional hole to press against the screw, thereby ensuring relative fixation between the screw sleeve and the screw and ensuring stability.
[0012] Furthermore, track wheels are provided on both sides of the traction frame. The track wheels correspond to the rail covers and are arranged on the corresponding rails during operation. The track wheels can ensure the smooth movement of the main push plate and reduce the connection pressure between the traction frame and the power traction vehicle during operation, so that there is always an upward erection force at the connection position between the power traction vehicle and the traction frame, which can reduce metal fatigue caused by pressure and increase service life.
[0013] Furthermore, a top eaves plate is provided on the top of the main push plate, and the top eaves plate is inclined toward the outside of the main push plate, which can effectively prevent the situation where too much gravel overflows to the inside of the main push plate, thereby increasing the protection for the shoveling and paving operation.

When the side of the fine-tuning plate flips downward, it will drive the extension rod to apply a downward pressure to the fixed welding plate, which will drive the fixed welding plate to move downward, and then drive the main push plate to move downward. Similarly, it can also drive the main push plate to move upward, so as to adjust the height of the main push plate shovel, which is convenient for the device to programmatically control the height of subway track gravel laying or cleaning, thereby improving practicality;

DETAILED DESCRIPTION
[0024] In order to make those skilled in the art better understand the technical solution of the utility model, the following will be combined with the attached Figure 1-4 The utility model is further introduced in detail.

When working, the rail cover 12 is sleeved on the outer side of the corresponding track to prevent stones from splashing and hitting the rails, thereby protecting the track and guiding the stones when cleaning the stones. When the shovel arc plate 11 pushes and shovels the stones on the inner side of the track, if there are too many stones accumulated in front of it, they will overflow to the outside of the track along the outer side of the rail cover 12, thereby eliminating the excess stones. In order to clean the stones, a top eave plate 14 is provided on the top of the main push plate 1. The top eave plate 14 is inclined toward the outside of the main push plate 1, which can effectively prevent the situation where too much stones overflow to the inside of the main push plate 1, thereby increasing the protection of the shoveling and paving operation. Action plates 13 are hinged on both ends of the main push plate 1, and the angle between the action plate 13 and the main push plate 1 can be adjusted. When the excess stones on the inner side of the track overflow to the outside of the track, the action plates 13 at both ends of the main push plate 1 will guide them again. The larger the angle between the action plate 13 and the inner side of the main push plate 1, the farther the position of guiding the stones is from the track, so that the distance of the excess stones from the track when cleaning the stones can be adjusted, which increases the practicality.
[0027] A longitudinal axis 18 is provided on one side of the action plate 13, and a plurality of sleeves 181 are sleeved on the outer side of the longitudinal axis 18. One side of the sleeves 181 is fixedly connected to the side of the main push plate 1. Two sets of connecting blocks 132 are fixedly provided on the adjacent side of the action plate 13 and the main push plate 1. One end of the connecting block 132 is fixedly connected to the corresponding longitudinal axis 18.

One end of the adjustment rod 131 is hinged to the inner side of the corresponding action plate 13, and the other end is arranged between the two layers of adjustment plates 19 and is fixed by bolts in the plug holes 191. After the action plate 13 adjusts the angle with the main push plate 1, the position of the action plate 13 is limited by fixing the adjustment rod 131 and the adjustment plate 19 with bolts, thereby ensuring stability during operation.
[0028] A plurality of reinforcing plates 15 are fixedly arranged on the inner side of the main push plate 1, and the rigidity of the main push plate 1 is increased by the reinforcing plates 15. Two sets of fixed welding plates 16 are fixedly connected to one side of the reinforcing plate 15, and the fixed welding plates 16 are connected to a linkage mechanism 2. One side of the linkage mechanism 2 is connected to the fixed welding plate 16 in a hinged manner and the other side is connected to the power tractor. The horizontal angle of the main push plate 1 can be fine-tuned through the linkage mechanism 2, and then the depth of the shovel arc plate 11 to clean the stones can be adjusted, and at the same time, it can adapt to different slopes of the track, thereby increasing the use effect. When operating on the track, the linkage mechanism 2 It is connected to a power tractor, which controls the rail covers 12 of the main push plate 1 to be erected above the track. Then, the main push plate 1 is adjusted in level and angle by the linkage mechanism 2 according to the terrain or the slope of the track. Finally, the main push plate 1 is pushed along the track by the power tractor. The arc shovel plate 11 in the main push plate 1 is used to spread or level and clean the stones on the inner side of the track. The action plates 13 on both sides can adjust the distance between the cleaned stones and the track, thereby achieving the purpose of automated cleaning and laying of stones on the track, abandoning the manual cleaning and laying of stones, which can save manpower and increase efficiency.
[0029] The linkage mechanism 2 includes a traction frame 21, a positioning plate 23, a fine-tuning plate 24, and a hydraulic cylinder 25. The traction frame 21 is connected to a traction vehicle that provides power drive. Track wheels 22 are provided on both sides of the traction frame 21. The track wheels 22 correspond to the rail covers 12. When working, the track wheels 22 are arranged on the corresponding rails. The track wheels 22 can ensure the smoothness of the main push plate 1 and reduce the connection pressure between the traction frame 21 and the power traction vehicle during operation, so that the connection position between the power traction vehicle and the traction frame 21 always has an upward erection force, which can reduce metal fatigue caused by pressure and increase service life.
[0030] A positioning plate 23 is provided at one end of the traction frame 21, a hydraulic cylinder 25 is provided on one side of the positioning plate 23, the bottom output end is hinged to the side of the fine-tuning plate 24, and extension plates are provided at both ends of the fine-tuning plate 24, and the extension plates correspond to the fixed welding plate 16 respectively. The top and bottom of the fixed welding plate 16 are provided with main hinge shafts 17, and the extension plates are respectively hinged to the fixed welding plate 16 through the main hinge shafts 17 at the bottom of the fixed welding plate 16 to realize the connection between the main push plate 1 and the linkage mechanism 2.

The top of the positioning plate 23 is provided with a fixed plate 231, and the fixed plate 231 is fixedly connected to the top of the hydraulic cylinder 25. The fixed placement of the hydraulic cylinder 25 is achieved by the fixed plate 231. The two ends of the top of the positioning plate 23 are respectively hinged with one end of a hinge rod 29, and the other end of the hinge rod 29 is respectively hinged to the fixed welding plate 16 through the main hinge shaft 17 at the top of the fixed welding plate 16. The hinge rod 29 further increases the stability of the hinge connection between the linkage mechanism 2 and the main push plate 1. When the height of the push shovel of the main push plate 1 needs to be adjusted, it can be achieved by the staff operating the hydraulic cylinder 25. Because the output end of the bottom of the hydraulic cylinder 25 is hinged to the edge of one side of the fine-tuning plate 24, and because the two ends of the fine-tuning plate 24 are hinged to the two sides of the bottom of the positioning plate 23, the hydraulic cylinder 25 will drive the fine-tuning plate 24 to flip around the hinge position with the positioning plate 23 as the axis when it works. When the side of the fine-tuning plate 24 flips downward, it will drive the extension rod 241 to The welding plate 16 applies a downward pressure. According to the principle that the positioning plate 23, the hinge rod 29, the fixed welding plate 16 and the extension rod 241 on the same side form a parallelogram frame hinged at the head and tail, one end of the extension rod 241 moves downward, which in turn drives the fixed welding plate 16 to move downward, and then drives the main push plate 1 to move downward. Similarly, it can also drive the main push plate 1 to move upward, so as to adjust the height of the push shovel of the main push plate 1, which is convenient for the device to programmatically control the height of subway track gravel laying or cleaning, thereby improving practicality.
[0031] The linkage mechanism 2 also includes a screw 26 and a screw sleeve 27. The screw 26 is arranged on one side of the positioning plate 23 and the top end is hinged to one side of the fixed plate 231. The screw 26 is connected with the screw sleeve 27 through a thread. The bottom end of the screw sleeve 27 is rotatably connected to a movable column 28. The bottom end of the movable column 28 is hinged to the top side of the traction frame 21. The angle of the main push plate 1 can be adjusted by cooperating with the screw 26 and the screw sleeve 27. After the height of the main push plate 1 is adjusted and fixed by the hydraulic cylinder 25, if the track has a slope or other situations require the paving angle to be changed, the staff can rotate the screw sleeve 27, and then the screw 26 will change the positional relationship with the screw sleeve 27 under the action of the thread, and the two will be adjusted. The length of the locating plate 23 will change, and because the bottom of the positioning plate 23 is hinged to one side of the traction frame 21 through the intermediate rod 232, the screw 26 will push or pull the positioning plate 23 to flip and tilt with the hinge position of the intermediate rod 232 and the traction frame 21 as the axis, thereby driving the main push plate 1 to tilt and flip as a whole, thereby changing the angle between the shovel arc plate 11 and the horizontal ground, thereby controlling the shoveling depth. For further practicality, a functional hole 271 with a thread is provided on one side of the screw sleeve 27. After the screw 26 is adjusted by the screw sleeve 27 to make the main push plate 1 tilt to a suitable angle, the screw can be screwed into the functional hole 271 to resist the screw 26, ensuring the relative fixation between the screw sleeve 27 and the screw 26 to ensure stability.
