Description

Technical Field

[0001] The utility model relates to the field of turnout pads, in particular to a small space anti-interference fastening pad for turnouts. Background Art

[0002] When the point rail in the turnout moves to change lanes, a pad needs to be set at the bottom to ensure the stability of the movement of the point rail. The bottom of the point rail is in sliding contact with the pad. After long-term use, the pad or the bottom of the point rail is easily worn, which causes the height of the point rail to drop, thereby causing the passing train to bump and affect the smoothness of the train. The existing maintenance method is to replace the point rail or the pad. During the replacement operation, both the entire point rail and the pad need to be replaced. The maintenance workload is large and the operation is complicated. In addition, the space at the turnout is limited, which further increases the difficulty of maintenance and replacement.

[0021] Reference Figure 1 and Figure 2The utility model is a small space anti-interference fastening pad for turnouts. The main structure includes a bottom plate 1, which is fixed to the bottom of the point rail by bolts. A slide plate 2 is slidably connected to the bottom plate 1. The point rail is fixed to the slide plate 2 by bolts or spring bars. When the point rail moves, the slide plate 2 slides on the bottom plate 1 to effectively support the movement of the point rail and ensure the smoothness of the movement of the point rail. A plurality of slide grooves 3 are provided on the bottom plate 1. The slide grooves 3 are opened on the top of the bottom plate 1 and extend downward from the top of the bottom plate 1. The bottom of the slide plate 2 is movably connected with a plurality of wear-resistant The ribs 4 are made of wear-resistant materials. A wear-resistant groove plate 5 is movably connected in the slide 3. The wear-resistant groove plate 5 is attached to the side wall of the slide 3. Specifically, a countersunk hole is set at the bottom of the wear-resistant groove plate 5. The bolt is fixed to the bottom of the slide 3 after passing through the countersunk hole so that the top of the bolt is not higher than the bottom of the wear-resistant groove plate 5. The wear-resistant groove plate 5 is movably connected to the slide 3 while avoiding interference with the sliding of the wear-resistant ribs 4. The wear-resistant ribs 4 are slidably connected in the wear-resistant groove plate 5. The sliding cooperation of multiple wear-resistant ribs 4 and the wear-resistant groove plate 5 realizes effective support for the movement of the slide plate 2 and the pointed rail thereon. , ensuring the stability of the position of the pointed rail after it moves, ensuring the smooth passage of the train, and at the same time, the cooperation of the wear-resistant ribs 4 and the wear-resistant groove plates 5 can extend the service life of the entire device and reduce the frequency of maintenance. The two sides of the slide plate 2 are symmetrically connected to a plurality of guide wheels 6 through bearings. The guide wheels 6 are in rolling contact with the side of the bottom plate 1. The setting of the guide wheels 6 can make the slide plate 2 and the pointed rail thereon move more smoothly, accurately guide the movement of the pointed rail, ensure the accuracy of the position of the pointed rail after it moves, and ensure the accuracy of the train changing lanes. One end of the bottom plate 1 is connected along the vertical sliding A limit seat 7 is connected to cooperate with the slide plate 2. The setting of the limit seat 7 can limit the maximum distance that the point rail moves in the direction away from the basic rail. When repairing, the limit seat 7 is slid downward so that the slide plate 2 and the point rail thereon can continue to slide away from the base plate 1, thereby exposing the wear-resistant groove plate 5 on the base plate 1 and the wear-resistant ribs 4 at the bottom of the slide plate 2, making the repair and replacement of both more convenient, and the repair in the limited space of the turnout is more convenient and efficient. The existing turnout structure will not interfere with the repair, further improving the efficiency and convenience of repair and replacement.

[0022] Preferably, refer to Figure 4 The longitudinal section of the wear-resistant rib 4 is U-shaped and is sleeved on the bottom of the slide plate 2. The wear-resistant rib 4 and the slide plate 2, and the wear-resistant groove plate 5 and the slide groove 3 are all connected by bolts. This structure makes it easier to disassemble and assemble the wear-resistant rib 4 and the wear-resistant groove plate 5. At the same time, the U-shaped structure of the wear-resistant rib 4 fits more closely with the bottom of the slide plate 2, further improving the stability of the wear-resistant rib 4 structure.

[0023] Preferably, guide plates 8 are symmetrically welded or integrally formed on both sides of the base plate 1, and the top height of the guide plates 8 is lower than the top height of the base plate 1. The guide wheels 6 are in rolling contact with the guide plates 8. Such a structure allows the height of the guide wheels 6 to be below the height of the top of the base plate 1, so that the guide wheels 6 are not likely to interfere with other structures of the turnout when the slide plate 2 and the point rail are moving, thereby further ensuring the smoothness of the movement of the point rail.

[0024] Preferably, refer to Figure 3 A concentric rim 9 is welded or integrally formed on the outer side of the guide wheel 6, and the diameter of the rim 9 is larger than the diameter of the guide wheel 6. The rim 9 contacts the side of the guide plate 8. Such a structure enables the cooperation of the rims 9 on both sides to limit the overall position of the slide plate 2 relative to the base plate 1, so that the point rail will not deviate during the movement process, accurately limit the direction of movement of the point rail, and ensure the accuracy of the movement of the point rail.

[0025] Preferably, the longitudinal section of the limit seat 7 is L-shaped, and the vertical part of the L-shape is slidably connected to the side of the base plate 1 to ensure the stability of the up and down sliding structure of the limit seat 7. The base plate 1 is provided with an adjustment rod 10 used in conjunction with the L-shaped horizontal part. The adjustment rod 10 realizes the up and down sliding adjustment of the limit seat 7 by cooperating with the L-shaped horizontal part, so that after the limit seat 7 is lowered as a whole, the adjustment rod 10 will not interfere with the continued sliding of the slide plate 2, thereby ensuring the convenience of maintenance operations.

[0026] Preferably, a fixing block 11 is welded or bolted to the end of the base plate 1, and the bottom of the adjusting rod 10 is rotatably connected to the fixing block 11 via a bearing. The adjusting rod 10 passes through the L-shaped transverse part and is threadedly connected to it. Such a structure only requires rotating the adjusting rod 10 to drive the limit seat 7 threadedly connected to it to slide up and down under the action of the threaded connection. The operation is convenient, the steps of adjusting the position of the limit seat 7 are simplified, and the efficiency of the maintenance operation is improved.

[0027] Working principle: The structure of the utility model is provided with a slide plate 2 slidingly on the bottom plate 1, the point rail is fixed on the slide plate 2, a plurality of wear-resistant ribs 4 are movably connected to the bottom of the slide plate 2, a wear-resistant groove plate 5 is movably connected in the slide groove 3 on the bottom plate 1, and the wear-resistant ribs 4 are slidably connected in the wear-resistant groove plate 5. Such a structure utilizes the sliding contact between the plurality of wear-resistant ribs 4 and the wear-resistant groove plate 5 to ensure the stability of the movement of the point rail on the slide plate 2, so that the service life of the device is longer, and the smooth passage of the train is ensured. After wear, only the wear-resistant ribs 4 and the wear-resistant groove plate 5 need to be replaced and repaired. At the same time, a limit seat 7 used in conjunction with the slide plate 2 is vertically slidably connected to one end of the bottom plate 1. Such a structure only needs to be replaced and repaired during maintenance. It is necessary to lower the limit seat 7 to below the top of the base plate 1 so that the slide plate 2 continues to slide away from the base plate 1, thereby exposing the wear-resistant ribs 4 and the wear-resistant groove plate 5, making the replacement operation steps simpler, and the maintenance in the limited space of the turnout more convenient and efficient.
