Abstract
Description
Technical Field
[0001] This utility model relates to the field of hook tail frames, specifically an impact-resistant and breakage-resistant hook tail frame. Background Technology
[0002] The coupler tail frame for railway locomotives and rolling stock is the main load-bearing component forming the coupler buffer device. The head of the coupler tail frame is connected to the coupler.
[0003] Chinese patent CN203996263U discloses a hook tail frame. This hook tail frame includes a connecting plate and a vertical plate at the port of the integral structure, a tail end, a hook tail pin support plate, and a fixing device. Vertical plates are located on the upper and lower sides of the connecting plate and the tail end, with the connecting plate at one end and the tail end at the other. A hook tail pin support plate is located on the vertical plate between the connecting plate and the tail end, and a fixing device for fixing the hook tail pin support plate is located on one side of the vertical plate. This hook tail frame has a unique structure that can meet the traction needs of locomotives pulling 10,000-ton trains. Its structural features significantly increase the traction force-bearing area at the head port of the hook tail frame, increase the horizontal swing angle of the coupler, and the hook tail pin support plate and the fixing device effectively connect the coupler to the hook tail frame via the hook tail pin, thus implementing the traction relationship between the locomotive and the vehicle.
[0004] If the hook tail frame of the above-mentioned patent is subjected to an impact from the side or from the front due to a misalignment of the carriage during use, the hook tail frame, lacking a reinforcing structure, is very likely to break. Summary of the Invention
[0005] The purpose of this invention is to provide an impact-resistant and fracture-resistant hook tail frame. This is achieved by providing reinforcing ribs at the upper and lower ends of the inner wall of the hook tail frame, and first and second stabilizing rods arranged in a crisscross pattern on the outer surfaces of both sides of the hook tail frame. Multiple first anti-collision blocks, made entirely of rubber, are also provided on the outer surfaces of both sides of the hook tail frame. When the hook tail frame is impacted from the side, the impacting object first contacts the first anti-collision blocks, preventing the impacting object from directly striking the surface of the hook tail frame and mitigating the impact force. Then, the first and second stabilizing rods reinforce the load-bearing capacity of the hook tail frame from top to bottom. Furthermore, the reinforcing ribs on the inner wall of the hook tail frame also enhance its strength, thus solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an impact-resistant and breakage-resistant hook tail frame, comprising a frame body main body, a connecting base plate provided at one end of the frame body main body, reinforcing ribs provided at both the upper and lower ends of the inner wall of the frame body main body, and first stabilizing rods provided on both sides of the outer surface of the frame body main body.
[0007] It also includes a second stabilizer bar, which is disposed on both sides of the outer surface of the main body of the frame. The main body of the frame is provided with first anti-collision blocks on both sides and a fixing block is provided at the front end of the main body of the frame. The fixing block has through holes.
[0008] Preferably, a connecting sleeve is provided between the fixing blocks, and the connecting sleeve is welded to the fixing blocks.
[0009] Preferably, the front end of the connecting sleeve is provided with an impact surface, and the impact surface is integrally formed with the connecting sleeve.
[0010] Preferably, the connecting sleeve has an anti-collision chamfer, which is integrally formed with the connecting sleeve.
[0011] Preferably, a second anti-collision block is provided on both sides of the fixing block, and the second anti-collision block is welded to the fixing block.
[0012] Preferably, a buffer pad is provided on the connecting base plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This utility model features reinforcing ribs at both the upper and lower ends of the inner wall of the hook tail frame, and first and second stabilizing rods arranged in a crisscross pattern on the outer surfaces of both sides of the hook tail frame. Multiple first anti-collision blocks, made entirely of rubber, are also provided on the outer surfaces of both sides of the hook tail frame. When the hook tail frame is impacted from the side, the impacting object first contacts the first anti-collision blocks, preventing the object from directly impacting the hook tail frame surface and mitigating the impact force. The first and second stabilizing rods then reinforce the top-to-bottom load-bearing capacity of the hook tail frame. Furthermore, the reinforcing ribs on the inner wall of the hook tail frame also enhance its strength. This effectively avoids the problem of existing hook tail frames, which are prone to breakage due to the lack of reinforcement structure when impacted from the side or from the front due to misalignment of the carriage.
