Description

Technical Field

[0001] This utility model relates to the field of locomotive maintenance technology, specifically to an auxiliary disassembly and assembly device for locomotive obstacle removal. Background Technology

[0002] Locomotive obstacle clearers are crucial safety devices for ensuring train operation safety. Like a "sweeper" in front of the locomotive, they actively remove or push away small, loose obstacles on the tracks through physical contact, preventing these obstacles from damaging the locomotive's running gear (wheelsets, bogies) or other critical equipment. This avoids serious accidents such as derailments and equipment failures, thus ensuring the safe and smooth operation of trains. During locomotive repairs or major overhauls, the removal and installation of the obstacle clearer are necessary. Traditional removal and installation methods typically rely on manual labor combined with forklifts, which is not only physically demanding but also poses significant safety hazards.

[0017] like Figure 1 As shown, this utility model provides an auxiliary disassembly and assembly device for a locomotive obstacle clearer, including a base frame 1 and a lifting platform. The base frame 1 has wheels 12. The lifting platform is fixed on the base frame 1. The lifting platform includes a lifting platform frame 2 and a lifting platform plate 3. The lifting platform plate 3 has a front limiting unit 4 and a rear support plate unit 5. The rear support plate unit 5 includes a telescopic sleeve and a support plate. The telescopic sleeve is divided into a sleeve and a telescopic rod. The sleeve is fixed on the lifting platform plate 3. The lower end of the telescopic rod extends into the sleeve and is slidably connected to the sleeve. The upper end of the telescopic rod is fixed to the support plate. A limiting bolt is provided on the side of the sleeve. One end of the limiting bolt can pass through the side wall of the sleeve and abut against the telescopic rod.

[0018] like Figure 2 , 3As shown, the front limiting unit 4 includes an adjustable baffle 45, two sliding rods 46, and two sets of U-shaped sliding plates 43. The U-shaped sliding plates 43 are assembled from a top plate, side plates, and a bottom plate. The lifting platform plate 3 has sliding grooves 31 that correspond one-to-one with the U-shaped sliding plates 43. The two sliding grooves 31 are located on both sides near the lifting platform plate 3. The inner side of the top plate has a slider 431 that is slidably connected to the sliding grooves 31. The bottom plate has a third fastening bolt 432. The end of the third fastening bolt 432 can abut against the bottom surface of the lifting platform plate 3. A support column 41 is fixed on the top plate. Multiple first mounting holes 411 are provided at intervals. At least one fixed slider 42 is slidably sleeved on the support column 41. The fixed slider 42 has a second fastening bolt 421 passing through the first mounting hole 411. The two ends of the adjustable baffle 45 are respectively connected to the fixed slider 42. Multiple second mounting holes 451 are provided at intervals on the side of the adjustable baffle 45. The top surface of the adjustable baffle 42 has a fourth fastening bolt 452 corresponding to the second mounting holes 451 one by one. The slide rod 46 is slidably connected to the second mounting holes 451. The end of the fourth fastening bolt 452 can abut against the slide rod 46.

[0019] When disassembling the obstacle remover 6 using the aforementioned device, the chassis 1 is placed at the bottom of the locomotive obstacle remover 6, and the lifting platform frame 2 is raised so that the front limiting unit 4 is aligned with the front end of the obstacle remover 6 and the rear support plate unit 5 is aligned with the rear crossbeam of the obstacle remover 6. The positions of the front limiting unit 4 and the rear support plate unit 5 are adjusted according to the actual situation to ensure good alignment with the front end and rear crossbeam of the obstacle remover 6, respectively. The adjustment method for the front limiting unit 4 is as follows: loosen the third fastening bolt 432 so that the U-shaped sliding plate 43 can slide along the slide groove 31 to the point where the U-shaped sliding plate 43 is closest to the front end of the obstacle remover 6; tighten the third fastening bolt 432; loosen the second fastening bolt 421 so that the fixed slider 42 can slide along the support column 41; and then... 2. After adjusting to the appropriate height, tighten the second fastening bolt 421, loosen the fourth fastening bolt 452, adjust the slide rod 46 so that its end can abut against the front end face of the obstacle remover 6, and tighten the fourth fastening bolt 452. Under the restriction of the slide rod 46, the obstacle remover 6 is prevented from moving forward. The tail support plate unit 5 is adjusted by adjusting the length of the extension sleeve of the telescopic rod so that the support plate supports the tail of the obstacle remover 6, preventing the obstacle remover 6 from moving backward. After the obstacle remover 6 is limited, use the braking system on the wheel to fix the wheel 12. Use tools to manually loosen the fasteners of the obstacle remover 6 and separate the obstacle remover 6 from the locomotive body 7. Control the lifting platform to lower the lifting platform plate 3 to a suitable position. Move the obstacle remover 6 to the designated position. The installation process is the reverse of the disassembly process. The lifting platform in this device can adjust the height of the limiting unit, the position of the front limiting unit 4 can be adjusted according to the vehicle model specifications, and the height of the tail support plate unit can be adjusted according to the vehicle model specifications. Therefore, this device is suitable for various vehicle models.

[0020] To avoid the device from damaging the surface of the obstacle remover 6, a flexible pad can be provided on the surface of the tray.

[0021] The frame 1 has a handlebar 13 to facilitate dragging the entire device.

[0022] One end of the slide rod 46 has a limiting end plate 461 to prevent the slide rod 46 from slipping out of the second mounting hole 451, and the other end has a flexible sleeve 462 to prevent the slide rod 46 from making hard contact with the obstacle remover 6.

[0023] To further limit the obstruction remover 6, the front limiting unit 4 also includes a bottom fixed baffle 44. The support column 41 has a fixed slider 42 connected to the bottom fixed baffle 44. The bottom fixed baffle 44 is fixed near the surface of the lifting platform plate 3. The bottom fixed baffle 44 is provided with an auxiliary sliding rod 46 to limit the front end of the obstruction remover 6.

[0024] The advantages of the above device compared with existing technologies are: a) Increased efficiency: Compared with the traditional manual operation method using a forklift, this device shortens the disassembly time; b) Reduced labor intensity: Reduced manual intervention, avoidance of prolonged use of hand tools and manual obstacle removal, and reduced physical exertion for workers; c) Safe and reliable: Through professional design, the frequency of personnel working under the vehicle is reduced, avoiding potential safety accidents during operation; d) Wide applicability: Applicable to the disassembly and assembly of obstacle removal devices for various models of locomotives.
