Description

Technical Field

[0001] This utility model belongs to the field of steel structure technology, and in particular relates to a lightweight steel structure reinforcement device for railway locomotives. Background Technology

[0002] With the development of railway transportation towards high speed and heavy load, higher requirements have been placed on the structural strength and lightweighting of locomotive bodies. Railway locomotive bodies generally adopt steel structure frames, among which the vertical beams are the main load-bearing components. In actual operation, the vertical beams need to withstand complex dynamic loads and impact vibrations, which can easily lead to stress concentration and fatigue damage. In order to enhance structural stability, it is usually necessary to add transverse connection structures between the vertical beams.

[0003] Currently, most common steel structure reinforcement methods for railway locomotives use bolted connections. In practical applications, multiple bolts are typically required at each connection point for fixation. While this multi-bolt connection structure offers some reliability, disassembly for maintenance is cumbersome due to the large number of bolts. Furthermore, traditional bolted connections lack effective quick positioning and guiding structures, necessitating repeated adjustments to the connector positions during installation. Therefore, we provide a lightweight steel structure reinforcement device for railway locomotives to address these issues. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] For a specific implementation example, please refer to Implementation Example 1. Figures 1-9 This utility model relates to a lightweight steel structure reinforcement device for railway locomotives, comprising a fixing component 1. The fixing component 1 includes a fixing frame 101, with two sets of bolt holes extending through the fixing frame 101. Trapezoidal limiting grooves 102 are formed on two opposite side walls of the fixing frame 101. A first limiting member 103 and a slotted plate 106 are fixedly mounted on the same side of the periphery of the fixing frame 101. The first limiting member 103 has a limiting groove 104. The fixing frame 101 also includes a horizontally extending support section 105. An L-shaped limiting slide groove 107 is formed on the slotted plate 106, which includes a vertical section and a horizontal section. An L-shaped connecting plate 108 is fixedly installed on the slotted plate 106. A rotating shaft 109 is fixedly installed between the slotted plate 106 and the L-shaped connecting plate 108. A cross rotating member 110 composed of mutually perpendicular horizontal plates and vertical plates is rotatably installed on the rotating shaft 109. It also includes a second limiting member 111. One end of the second limiting member 111 is attached to the upper surface of the horizontal plate of the cross rotating member 110. A T-shaped slider 112 is fixedly installed on the side of the second limiting member 111 near the slotted plate 106. The T-shaped slider 112 is slidably installed in the vertical section of the L-shaped limiting groove 107. The connecting component 2 is slidably installed on the fixed component 1.

[0025] The connecting component 2 includes a connecting frame 201. A matching trapezoidal protrusion 202 is fixedly disposed on the side of the connecting frame 201 near the trapezoidal limiting groove 102. A guide post 203 and a second limiting part are fixedly disposed on the same side surface of the connecting frame 201 as the first limiting member 103. Two bolt holes are formed through the connecting frame 201 near the first limiting part. The second limiting part includes a fixing plate 205. A limiting post 206 is fixedly disposed on the fixing plate 205. A limiting cavity 207 is formed inside the limiting post 206. A guide hole 208 is formed at the bottom of the limiting cavity 207, and a clearance groove 209 is formed on its peripheral side. A third limiting member 210 is slidably disposed within the limiting cavity 207. The lower end is slidably disposed in the guide hole 208, and its upper end extends to the outside through the clearance slot 209. A spring 211 is fixedly connected between the upper surface of the limiting cavity 207 and the upper surface of the third limiting member 210. A crossbeam guide groove 204 is opened on the two opposite inner surfaces of the connecting frame 201. A connecting plate 212 is fixedly disposed between the two inner surfaces. The crossbeam 3 is slidably disposed on the connecting assembly 2. Guide blocks 301 that are adapted to the crossbeam guide groove 204 are fixedly disposed on both sides of the crossbeam 3. A bolt plate 302 is fixedly disposed on the upper surface of the crossbeam 3 near the connecting assembly 2. Two bolt holes are opened on the bolt plate 302. Two sets of bolt holes corresponding to the fixed frame 101 are opened on the vertical beam 4.

[0026] The operation process of this embodiment is as follows: First, the fixing component 1 is horizontally and tightly attached to the vertical beam 4. Then, the trapezoidal protrusion 202 of the connecting component 2 is aligned with the trapezoidal limiting groove 102 of the fixing component 1 and slid down along the groove. During this process, the lower end of the third limiting member 210 on the connecting component 2 slides along the inclined surface of the first limiting member 103 and is squeezed, compressing the spring 211. When it slides to the designated position, the third limiting member 210 falls into the limiting groove 104 under the action of the spring 211 to complete the positioning and limiting. At the same time, the guide post 203 contacts and pushes the horizontal plate of the cross rotating member 110 during the downward movement, causing it to rotate clockwise around the rotating axis 109, driving the plate placed on it to rotate clockwise. The second limiting member 111 rises, and when the guide post 203 passes the highest point of the cross rotating member 110, the second limiting member 111 falls back under the action of gravity. Its inverted L-shaped structure forms a mechanical self-lock to prevent the connecting component 2 from moving in the opposite direction. Then, the lower bolt holes of the fixing frame 101, the lower bolt holes of the vertical beam 4, and the bolt holes of the connecting frame 201 are fixedly connected by bolts. Then, the crossbeam 3 is slid into the crossbeam guide groove 204 through the guide block 301, so that the bolt holes on the bolt plate 302 are aligned with the upper bolt holes of the fixing component 1. The upper bolt holes of the fixing frame 101, the upper bolt holes of the vertical beam 4, and the bolt holes of the bolt plate 302 are fixedly connected by bolts.

[0027] When disassembly is required, first remove the fixing bolts of the crossbeam 3, take the crossbeam 3 upward along the crossbeam guide groove 204, then manually move the second limiting member 111 to the horizontal section of the L-shaped limiting slide groove 107, so that the second limiting member 111 disengages from the contact with the cross rotating member 110 and releases the mechanical self-locking, remove the fixing bolts of the connecting component 2, move the third limiting member 210 along the relief groove 209 to release the third limiting member 210 from the limit, at this time the connecting component 2 can be lifted upward and the connecting component 2 can be removed from the fixed component 1, and finally the fixed component 1 is removed to complete the entire disassembly process.
