Description

Technical Field

[0001] The utility model belongs to the technical field of special vehicle accessories, and specifically relates to a traction pin plate. Background Art

[0002] In the tow pin installation assembly currently on the market, the tow pin reinforcement beam is welded to the tow pin plate, the longitudinal direction of the weld is perpendicular to the longitudinal direction of the tank car, and the tow pin longitudinal reinforcement beams are respectively welded at the four corners of the tow pin reinforcement beam for reinforcement.

[0003] However, the above-mentioned traction pin plate still has the following disadvantages:

[0004] In the existing tow pin installation assembly, the weld between the tow pin reinforcement beam and the tow pin plate is perpendicular to the axle. During the acceleration and deceleration of the vehicle, in addition to the stress on the welding position of the tow pin plate, there is still a large stress between the tow pin and the tow pin reinforcement beam. The weld adopts the original style and has a large stress area, but due to the small size and thickness of the weld, the overall stress effect of the original style is not ideal. Utility Model Content

[0005] The utility model provides a traction pin plate, which solves the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a traction pin plate, including a traction pin plate and a traction pin reinforcement beam, traction pin longitudinal reinforcement beams are welded on both sides of the top and both sides of the bottom of the traction pin reinforcement beam, the bottom of the traction pin longitudinal reinforcement beam is welded to the top of the traction pin plate, sealing plates are welded on both sides of the traction pin reinforcement beam, and a traction pin passes through the top of the traction pin plate.

[0007] Preferably, the longitudinal direction of the traction pin reinforcement beam is parallel to the center axis of the tank truck, and the weld between the traction pin reinforcement beam and the traction pin plate is parallel to the center axis of the tank truck.

[0008] The beneficial effects of adopting the above technical solution are:

[0009] 1. Compared with the original structure, the new structure of the utility model fully considers the form and performance of the weld. Although the original structure increases the stress-bearing area when subjected to longitudinal force, the weld is a fillet weld with a narrow weld width, which makes it easier to break after being subjected to force. After changing to the existing structure, the weld direction is along the longitudinal direction of the tank truck. Although the stress-bearing area is reduced, the longitudinal size of the weld is larger, and the load-bearing effect is more obvious.

[0010] 2. According to CAE analysis, during the longitudinal travel of the tank truck, the maximum stress point of the original structure is 154MPa. After changing to the structure of the utility model, the maximum stress point is 100.4MPa, and the safety performance is significantly improved.

[0011] 3. According to CAE analysis, the maximum stress point of the tank truck is 127.6MPa during the turning process. Compared with the original structure, the stress condition of the utility model structure has not deteriorated. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping technicians in the field to have a more complete, accurate and in-depth understanding of the concept and technical solution of the utility model and facilitating its implementation.

[0017] like Figures 1 to 2 As shown, the utility model is a traction pin plate. Compared with the original structure, the form and performance of the weld are fully considered. Although the original structure increases the stress-bearing area when subjected to longitudinal force, the weld is a fillet weld with a narrow weld width, which makes it easier to break after being subjected to force. After being changed to the existing structure, the weld direction is along the longitudinal direction of the tank truck. Although the stress-bearing area is reduced, the longitudinal size of the weld is larger, and the load-bearing effect is more obvious.

[0018] Specifically, Figures 1 to 2 As shown, it includes a traction pin plate 1 and a traction pin reinforcement beam 2, and traction pin longitudinal reinforcement beams 3 are welded on both sides of the top and both sides of the bottom of the traction pin reinforcement beam 2, the bottom of the traction pin longitudinal reinforcement beam 3 is welded to the top of the traction pin plate 1, and sealing plates 4 are welded on both sides of the traction pin reinforcement beam 2, and a traction pin 5 passes through the top of the traction pin plate 1.

[0019] The longitudinal direction of the traction pin reinforcement beam 2 is parallel to the central axis of the tank truck, and the weld between the traction pin reinforcement beam 2 and the traction pin plate 1 is parallel to the central axis of the tank truck.

[0020] The specific working method is described below with specific embodiments: Example 1

[0021] The longitudinal direction of the traction pin reinforcement beam 2 is parallel to the center axis of the tank car, and the weld between the traction pin reinforcement beam 2 and the traction pin plate 1 is parallel to the center axis of the tank car;

[0022] The current traction pin longitudinal reinforcement beam 3 is still welded at the four longitudinal corners of the traction pin reinforcement beam 2. The position of the traction pin longitudinal reinforcement beam of the new structure is the original structure rotated 90° around the central axis of the traction pin;

[0023] The direction of the weld is along the longitudinal direction of the tank truck. Although the load-bearing area is reduced, the longitudinal dimension of the weld is larger and the load-bearing effect is more obvious.

[0024] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above-mentioned concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
