Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle body steel structure technology, and in particular to a web reinforcement structure for high-speed railway traction beams. Background Technology
[0002] The car body steel structure is an important component of the train, and the traction beam is an important part of the car body steel structure. During the operation of the car body, the traction beam not only transmits traction and braking forces to the coupler, but also bears the forces of various equipment loads and horizontal longitudinal and lateral impact loads during traction. Therefore, the traction beam must have sufficient strength and rigidity to meet the requirements of relevant technical standards and ensure the safety and stability of train operation.
[0003] In actual use, the following shortcomings have been found in the existing high-speed rail traction beams:
[0004] In order to enable the coupler to rotate left and right, the end of the traction beam where the coupler is installed is opened into a trumpet shape. After the end is bent, the strength is reduced, and the overall buckling phenomenon of the web is mainly concentrated in the bending-shear-torsion segment near the fixed end. When torsional failure occurs, the overall buckling phenomenon of the web is mainly concentrated in the bending-torsion segment at the mid-span. The buckling of the beam web leads to a decrease in the overall strength of the beam.
[0005] Therefore, this application provides a web reinforcement structure for high-speed railway traction beams to meet the requirements. Utility Model Content
[0006] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a web reinforcement structure for high-speed railway traction beams.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0008] A web reinforcement structure for a high-speed railway traction beam includes: a traction beam, a lower cover plate, a partition plate, a connector, reinforcing ribs, and stiffeners. The traction beam is composed of a web and flanges. The web is located in the middle of the traction beam, and flanges are welded to the upper and lower ends of the web. The lower cover plate is welded to the traction beam, and a partition plate is welded to the upper end of the lower cover plate. A connector is welded to the inner end of the traction beam, and a side plate is provided on the side of the connector. Reinforcing ribs are welded to the side of the traction beam, and stiffeners are welded to the side of the reinforcing ribs.
[0009] Preferably, the traction beam is made of two channel steels, and the ends of the traction beam are opened into a flared shape.
[0010] Preferably, the partition is vertically installed on the inner side of the traction beam, and the left and right ends of the partition are welded to the back of the web.
[0011] Preferably, the connector is installed laterally at the end of the traction beam, and the side plate of the connector is welded to the back of the web plate.
[0012] Preferably, the side plate of the connector is trapezoidal, and the bend of the side plate forms two sets of included angles.
[0013] Preferably, the reinforcing rib is vertically mounted on the front of the web and is located on the inner side of the wing plate.
[0014] Preferably, the reinforcing member is provided in two sets, and the two sets of reinforcing members are respectively welded to the upper and lower corners of the reinforcing rib.
[0015] Preferably, the stiffener is L-shaped, and the stiffener extends outward and is welded to the connection between the web and the wing plate. The other end of the stiffener is laterally attached to the surface of the wing plate and extends to the edge of the wing plate.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects:
[0017] In the above scheme, the connector is installed laterally at the end of the traction beam, and the side plate of the connector is welded to the back of the web plate, which can ensure the connection area with the web plate. The bend of the side plate forms two sets of included angles, which makes the side plate of the connector less prone to deformation when bearing the shear load and bending load of the beam. This increases the local stiffness of the web plate of the traction beam and provides support through its own strength and stiffness, thereby reducing the possibility of web plate buckling due to local instability at the traction port of the traction beam coupler.
[0018] In the above scheme, reinforcing ribs are welded to the front of the web, and stiffeners are welded to the corners of the upper and lower ends of the reinforcing ribs. The two sets of stiffeners can be welded and fixed to the flanges. The web's support capacity is enhanced by constraining the edges. The other end of the stiffeners is laterally attached to the surface of the flange and extends to the edge of the flange. At the edge, the reinforcing ribs and stiffeners can be connected to the upper and lower flanges, thereby restricting the lateral displacement of the web and improving its support capacity.
