Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, specifically to a sleeper resistance enhancer. Background Technology

[0002] The utility model patent with application number CN201921368612.0—a transverse resistance enhancement structure for railway sleepers, connected to both ends and the middle of a concrete sleeper; includes: hoop plates and wing plates; two hoop plates symmetrically wrap around the side and top walls of the concrete sleeper, the shape of the hoop plates conforming to the shape of the concrete sleeper, corresponding bolt holes are opened on the top of the two hoop plates, and the tops of the two hoop plates are fastened together at intervals by bolts passing through the bolt holes, so that the hoop plates clamp the concrete sleeper; the edge of the wing plate is vertically fixed to the outer wall of the hoop plate, and the bottom end extends out of the bottom surface of the concrete sleeper and is inserted into the ballast of the railway line.

[0003] This patent proposes inserting wing plates into the ballast of railway lines to address the problem of insufficient lateral resistance in concrete sleepers. However, the patent only fixes the upper part of the two wing plates with bolts, leaving the lower part open, resulting in a weak and loose connection. If the sleeper experiences lateral displacement, it is easy for the sleeper to move while the lateral resistance-enhancing structure remains stationary, significantly reducing its effectiveness in transferring lateral resistance from the sleeper to the roadbed.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows: Example 1: A sleeper resistance enhancer includes a first hoop plate 1, a connecting mechanism 2, and a second hoop plate 3 connected in sequence. The other ends of the first hoop plate 1 and the second hoop plate 3 are connected by a shovel plate 4. The shovel plate 4, the first hoop plate 1, the connecting mechanism 2, and the second hoop plate 3 form a clamping structure. The clamping structure is used to firmly connect the resistance enhancer to the sleeper. The shovel plate 4 extends downward on the side away from the first hoop plate 1 and the second hoop plate 3. The shovel plate 4 extends downward and inserts into the coarse gravel or crushed stone of the roadbed, thereby transferring the lateral force on the sleeper to the roadbed and effectively preventing the sleeper from lateral displacement.

[0018] It should be noted that the shapes of the first hoop plate 1 and the second hoop plate 3 are consistent with the shapes of the side wall and upper end face of the sleeper, which allows for better fit and improves the tightness of the connection. Specifically, the shovel plate 4 includes plates A41 and B42 that are fixedly connected. The first hoop plate 1 and the second hoop plate 3 are respectively fixedly arranged on both sides of plate A41. The angle between plate A41 and the first hoop plate 1 is α, and the angle between plate A41 and plate B42 is α. Plate C43 is fixedly arranged on the side of plate B42 away from plate A41. The angle between plate C43 and plate B42 is α. In this embodiment, α is 90°. In other embodiments, α can also be 100°, 110°, 120°, 130°, 140°, or 150°. The above settings facilitate the transmission of force between plate A41, plate B42, and plate C43, further improving the stability of the sleeper resistance enhancer.

[0019] It should be noted that the width of plate C43 is greater than that of plate A41, which increases the contact area with the roadbed.

[0020] Furthermore, the connecting mechanism 2 is a bolt structure, and the first hoop 1 and the second hoop 3 are connected by bolts.

[0021] Specifically, the bolt structure includes a sleeve 5, a fixing nut 6, and a bolt 7. One end of the bolt 7 passes through the sleeve 5 and is threadedly connected to the fixing nut 6. The bolt 7 can move radially within the sleeve 5 within a certain range. The sleeve 5 is fixedly installed on the outside of the first hoop 1, and the fixing nut 6 is fixedly installed on the outside of the second hoop 3. The above structure design has low cost and is easy to process and manufacture.

[0022] It should be noted that, based on the above embodiments, in another embodiment, the sleeve 5 is provided with a thread for connection with the bolt 7, so as to prevent the bolt 7 from falling out of the sleeve 5 when it is separated from the fixing nut 6.

[0023] The first hoop 1 and the second hoop 3 have a certain deformation capacity.

[0024] Example 2: The connecting mechanism 2 includes a screw 8 that is hinged to the first hoop 1. The screw 8 is threadedly connected to a movable nut 9. The second hoop 3 is fixedly provided with a stop block 10 that blocks the movable nut 9. The stop block 10 is located on both sides of the screw 8. The above structural design reduces costs while facilitating disassembly and installation.

[0025] Example 3: The connecting mechanism 2 is a snap fastener. The existing snap fastener is directly installed on the first hoop plate 1 and the second hoop plate 3. Although the cost increases, it is convenient for installation and disassembly. By designing different connection mechanisms, a flexible connection between the first hoop plate and the second hoop plate is achieved, which not only ensures the firmness of the connection, but also facilitates installation and disassembly.

[0026] Example 4: A horizontal plate 11 is fixedly installed on the lower end face of the shovel plate 4 to solve the problem of insufficient longitudinal resistance of the sleeper when the train brakes, so as to transfer the longitudinal force on the sleeper to the roadbed and improve the structural stability; at the same time, it can improve the stability of the shovel plate 4 structure and play a strengthening role.

[0027] The working principle and process of this utility model are illustrated below with Example 1: First, clear the coarse gravel or pebbles on both sides of the sleeper to provide enough space for installing the sleeper resistance enhancer. Then, fit the clamp structure into the sleeper and rotate the bolt 7. The bolt 7 is threadedly connected to the fixing nut 6. Under the action of the bolt 7, the upper parts of the first clamp plate 1 and the second clamp plate 3 are gradually pulled closer, thereby clamping the clamp onto the sleeper. Then, backfill the area around the shovel plate with coarse gravel or pebbles.

[0028] When the sleeper is subjected to lateral force, the lateral force is transferred to the roadbed through the shovel plate 4.
