[0001] The utility model relates to the technical field of railway construction equipment protection, in particular to a railway ballast scraper. Background Art

[0002] Railway ballast is the coarse gravel or crushed stone used to pave the railway subgrade. In the railway transportation system, railway ballast is used as crushed stone to support the track sleepers. It is a common track bed structure. Only after the railway ballast is flattened and compacted will the sleepers and rails be laid.

[0003] During the frequent operation of the railway, the ballast at the bottom of the sleeper will be pressed to both sides of the roadbed and scattered outside the track. Railway workers are required to spread the ballast that has fallen to both sides of the roadbed back on the roadbed every once in a while.

[0004] The existing working method is that the maintenance personnel pour the ballast into the roadbed and then manually spread it with tools. However, the manual paving method is slow and labor-intensive. Therefore, a railway ballast scraper is proposed to solve the above technical problems. Utility Model Content

The upper end of the hydraulic cylinder is fixed with a vertical rod, and the vertical rod is rotatably connected to the extension arm. The hydraulic cylinder telescopic rod is movably connected to the supporting frame.

[0013] Preferably, the receiving frame includes two support rods and a mounting plate, the support rods are arranged in a V shape, and the mounting plate is fixed between the two support rods;

[0014] A first mounting block is fixed below the crossbeam, and a first ball head is fixed at one end of the two support rods, and the first ball head is movably connected to the first mounting block;

[0015] A second ball head is fixed above the mounting plate, a second mounting block is fixed to the end of the telescopic rod of the hydraulic cylinder, and the second ball head is movably connected to the second mounting block.

[0016] Preferably, a counterweight is fixed to one end of the crossbeam away from the traveling vehicle, and the first mounting block is fixedly connected to the counterweight.

[0017] Preferably, the scraper assembly further comprises a turntable, which is rotatably connected to the bottom of the mounting plate, and the scraper is fixedly connected to the turntable.

[0029] The present application is further described in detail below in conjunction with all the drawings and specific embodiments.

[0030] Reference Figure 1 The present invention provides a railway ballast scraper for scraping ballast while traveling on rails. The ballast scraper comprises a traveling vehicle 1 and a scraping assembly 2. The scraping assembly 2 is fixed to one end of the traveling vehicle 1. The traveling vehicle 1 may be a heavy vehicle with rail wheels disposed underneath. The traveling vehicle 1 is capable of traveling along the rails, driving the scraper assembly to scrape the ballast. The structure of the traveling vehicle 1 is prior art and will not be described in detail in this application.

[0031] Reference Figure 1 and Figure 2 The scraping assembly 2 includes a crossbeam 3, a connecting frame 4, a hydraulic cylinder 5, a receiving frame 6, a turntable 7, and a scraper 8. The crossbeam 3 is fixed to the vehicle body at the head of the traveling vehicle 1. The connecting frame 4 includes a connecting rod 41 and two lugs 42. The connecting rod 41 is fixed between the two lugs 42. The two lugs 42 and the connecting rod 41 form a mounting groove. The crossbeam 3 is fixed in the mounting groove, so that the connecting frame 4 can be fixed to the crossbeam 3 and connected to the scraper 8 below.

[0032] Extension arms 43 are rotatably connected to both sides of the connecting frame 4. Specifically, the extension arms 43 are rotatably connected to the lugs 42. The rotation axis of the extension arms 43 is aligned with the extension direction of the crossbeam 3, allowing the extension arms 43 to swing up and down. Vertical rods 51 are fixed to the upper ends of the hydraulic cylinders 5. The two vertical rods 51 are rotatably connected to the ends of the extension arms 43 away from the connecting frame 4. The two vertical rods 51 are located on opposite sides of the extension arms 43, allowing the vertical rods 51 to drive the hydraulic cylinders 5 to swing.

[0033] Reference Figure 3 and Figure 4 A counterweight block 31 is fixed to the end of the beam 3 away from the traveling vehicle 1, and two track wheels 32 are rotatably connected to the bottom of the counterweight block 31. A first mounting block 311 is fixed to the lower side of the counterweight block 31. The first mounting block 311 is arranged close to the side of the traveling vehicle 1. The head of the first mounting block 311 can cooperate with the supporting frame 6 so that one end of the supporting frame 6 is movably connected to the bottom of the beam 3.

[0034] The supporting frame 6 includes two support rods 61 and a mounting plate 62. The two support rods 61 are arranged in a V shape. The mounting plate 62 is fixed between the two support rods 61. The end positions of the two support rods 61 are provided with first ball heads 611. The first ball heads 611 are movably connected to the first mounting block 311. The first ball head 611 can move in the first mounting block 311, so that one end of the supporting frame 6 is movably connected to the bottom of the beam 3.

[0035] Two second ball heads 621 are fixed above the mounting plate 62. The second ball heads 621 are located on the side of the support rod 61 away from the first ball head 611. The ends of the telescopic rods of the two hydraulic cylinders 5 are fixed with second mounting blocks 52. The second ball heads 621 are movably connected to the second mounting blocks 52, allowing the telescopic rods of the hydraulic cylinders 5 to be movably connected to the support frame 6. When the hydraulic cylinder 5 on one side is in operation, the telescopic rod of the hydraulic cylinder 5 can be extended and retracted, thereby driving the movement of the second mounting block 52. The movement of the second mounting block 52 can cause one side of the support frame 6 to tilt up or down.

[0036] Reference Figure 5 The turntable 7 is rotatably connected to the bottom of the mounting plate 62. A gear ring 71 is fixed inside the turntable 7. A gear 622 is rotatably connected to the bottom of the mounting plate 62. The gear 622 is connected to the inner core of the gear ring 71. When the gear 621 rotates, it can drive the gear ring 71 to rotate, thereby driving the turntable 7 to rotate. The scraper 8 is fixed to the bottom of the turntable 7. The scraper 8 can rotate with the turntable 7 to adjust the position of the scraper 8. It should be noted that a motor that drives the gear 622 can be fixed on the upper side of the mounting plate 62. This is a prior art and is not shown in the figure in this application.

[0037] During the ballast scraping operation, the staff can drive the traveling vehicle 1 to move on the rails, thereby driving the scraping assembly 2 to move. As the scraping assembly 2 moves, the ballast can be gradually scraped flat by the scraper 8. When the scraper 8 moves, the two hydraulic cylinders 5 are not working. Since the length of the hydraulic cylinders 5 is fixed, the length of the scraper 8 and the extension arm 43 can be moved, and the height of the scraper 8 can be maintained to ensure the scraping effect. When the hydraulic cylinders 5 are working, the telescopic rod of the hydraulic cylinder 5 on one side moves downward, which can drive the scraper 8 on one side to tilt downward and the scraper 8 on the other side to tilt upward. The hydraulic cylinder 5 and the extension arm 43 on the other side swing upward, so that the smooth tilting and swinging of the scraper 8 can drive the scraper 8 to tilt and scrape the ballast on one side. The scraper 8 can also rotate in place with the rotation of the turntable 7, so that the ballast scraping vehicle can not only replace manual ballast scraping, improve paving efficiency, and reduce labor costs, but also can adjust the angle of the scraper 8 as needed, with good applicability.

[0038] As an embodiment, a connecting rod 44 is fixed to the lower side of the two extension arms 43, and a connecting bar 45 is rotatably connected between the two connecting rods 44. The connecting bar 45 is an arc-shaped metal bar. The connecting bar 45 can connect the extension arms 43 on the left and right sides together. When the extension arm 43 on one side rotates upward, it can drive the extension arm 43 on the other side to rotate downward, so that the scraper 8 can be smoothly tilted on one side.

[0039] As an embodiment, two avoidance grooves 81 are opened on the lower side of the scraper 8. The width of the two avoidance grooves 81 is greater than the width of the rails. The avoidance grooves 81 can allow the rails to pass through to prevent the rails from affecting the movement of the scraper 8.

[0040] The working principle of the present invention is as follows: during ballast scraping, a worker can drive the traveling vehicle 1 to move on the rails, thereby driving the scraping assembly 2 to move. As the scraping assembly 2 moves, the ballast can be gradually scraped flat by the scraper 8. When the scraper 8 moves, the two hydraulic cylinders 5 are not working. Since the length of the hydraulic cylinders 5 is fixed, the length of the scraper 8 and the extension arm 43 can be moved, and the height of the scraper 8 can be maintained to ensure the scraping effect. When the hydraulic cylinders 5 are working, the telescopic rod of the hydraulic cylinder 5 on one side moves downward, which can drive the scraper 8 on one side to tilt downward and the scraper 8 on the other side to tilt upward. The hydraulic cylinder 5 and the extension arm 43 on the other side swing upward, so that the smooth tilting and swinging of the scraper 8 can drive the scraper 8 to tilt and scrape the ballast on one side. The scraper 8 can also rotate in place as the turntable 7 rotates. This allows the ballast scraper to not only replace manual ballast scraping, improve paving efficiency, and reduce labor costs, but also adjust the angle of the scraper 8 as needed, thus having good applicability.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
