Description

Technical Field

[0001] The invention relates to the technical field of dismantling scrapped railway carriages, and in particular to a 180-degree turning machine for a railway freight car chassis. Background Art

[0002] With the development of railway technology, more than 20,000 railway freight cars need to be scrapped every year. The scrapped railway freight cars need to be dismantled, among which chassis flipping is one of the key processes. The railway freight car chassis weighs 7-8 tons, is 12.5-13 meters long, and is 2.8-2.9 meters wide. Its structure is special, with a flat plate structure on the upper part and a steel structure on the lower part. It is difficult to dismantle the chassis from the upper part, so it is necessary to flip the chassis 180 degrees and then cut and disassemble it. The 180-degree flipping machine currently driven by hydraulic cylinders cannot effectively clamp the freight car chassis of different thicknesses during the flipping process. Therefore, the railway freight car chassis is often severely damaged during the flipping process, and its adaptability, reliability and safety are poor. In addition, the current 180-degree flipping machine based on gears or sprockets needs to lift the chassis to a specific height through a rail car with a lifting function, and then clamp and flip the two ends of the chassis. Its structure is relatively complex, the flipping speed is slow, and the work efficiency is low. Summary of the invention

[0026] The working principle of the present invention is as follows: First, the railway freight car chassis 6 is hoisted onto the overturning frame 2 and placed close to the buffer device 3, such as Figure 8 a; then the clamping hydraulic cylinder 404 drives the clamping plate 402 to rotate counterclockwise around the rotating shaft 405, and at the same time cooperates with the sliding hydraulic cylinder 409 to drive the sixth hinge seat 406 to slide on the guide rail 408 to achieve the clamping of the railway truck chassis 6, such as Figure 8 b; then the hydraulic cylinder 5 drives the flip frame 2 and the railway truck chassis 6 to rotate clockwise around the flip hinge 104, as shown in FIG. Figure 8 c; during the rotation process, under the action of gravity of the railway freight car chassis 6, the buffer spring 305 in the buffer device 3 is gradually compressed until the railway freight car chassis 6 slowly contacts the overturning frame 2, thereby protecting the overturning frame 2 and the railway freight car chassis 6. When the overturning frame 2 rotates to contact the upper side of the right oblique support frame 103, the overturning hydraulic cylinder 5 stops working, as shown in FIG. Figure 8d; then the clamping hydraulic cylinder 404 drives the splint 402 to rotate clockwise around the rotating shaft 405. Since the right oblique support frame 103 is higher on the left and lower on the right, the railway truck chassis 6 will tilt to the right along with the splint 402 under the action of gravity to complete a 180-degree flip, such as Figure 8 e and 8f; during this process, the gravity exerted on the buffer device 3 from the railway freight car bottom frame 6 gradually decreases, the buffer spring 305 is released and drives the spring top plate 304 and the railway freight car bottom frame 6 to move upward, at which time the inclined surface of the spring top plate 304 is in direct contact with the railway freight car bottom frame 6, thereby protecting both the tipping frame 2 and the railway freight car bottom frame 6.

[0027] In summary, the 180-degree turning machine for railway freight car underframes drives the clamping plate 402 to rotate around the rotating shaft 405 through the clamping hydraulic cylinder 404, and drives the sixth hinge seat 406 to slide on the guide rail 408 through the sliding hydraulic cylinder 409, thereby achieving effective clamping of railway freight car underframes 6 of different thicknesses, and cooperating with the buffer device 3 to protect the turning frame 2 during the turning process, so that it has higher adaptability, safety and reliability.

[0028] The 180-degree turning machine for a railway freight car chassis drives the turning frame 2 and the railway freight car chassis 6 to rotate around the turning hinge seat 104 through the turning hydraulic cylinder 5. When the turning frame 2 contacts the top of the right oblique support frame 103, the railway freight car chassis 6 will tilt to the right along the clamping plate 402 under the action of gravity, thereby realizing a 180-degree turning of the railway freight car chassis 6. This method of using the hydraulic cylinder and the self-gravity of the railway freight car chassis 6 to turn 180 degrees has the advantages of simple structure and fast turning speed.
