Technical Field

[0001] The utility model relates to the technical field of rubber damping pads, and particularly relates to a wear-resistant railway rubber damping pad. Background Technique

[0002] A railway is a rail line on which ground transportation tools such as trains, cable cars, and ropeways travel. It not only reduces the frictional resistance of the top appliances but also disperses the weight of the transportation tools from both sides. In order to build a railway, it is often necessary to install a damping rubber pad under the track to prevent the support tools such as sleepers from breaking due to the direct pressing conflict with the ground when trains and other equipment move through here.

[0003] Ordinary damping pads are made of a complete one-piece formed rubber material, which is cut according to the requirements of assembly and then assembled between the sleeper and the ground, or it can also be between the sleeper and the rail. However, the ordinary rubber pad has a single structure, the surface material is thin, the gripping ability is reduced, and it is also easy to crack and fragment.

[0004] Now, a new type of wear-resistant railway rubber damping pad is proposed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wear-resistant railway rubber damping pad to solve the problem of the pad not being wear-resistant proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A wear-resistant railway rubber damping pad, including a rubber pad and raised rubber ribs. Four groups of raised rubber ribs are fixed between the front and back of the upper surface of the rubber pad, and a frosted sticker is attached to the surface of the raised rubber ribs. A rectangular chamber is formed on the surface of the rubber pad between the raised rubber ribs, and a support sleeve is fixed at the center between the front and back of the top of the rectangular chamber. Hollow sleeves are respectively fixed between the front and back of the two sides of the outside of the support sleeve. Arc-shaped strips are fixed between the front and back of the top of the outside of the support sleeve. A layer of frosted bottom pad is fixed on the surface of the bottom of the rubber pad.

[0008] Preferably, the inner chamber of the support sleeve is communicated with the hollow sleeves on both sides, and both sides of the arc-shaped strip are respectively lapped on the raised rubber ribs.

[0009] Preferably, insertion blocks are respectively fixed at the front and rear ends of the outer side of the left side of the rubber cushion plate, and threaded grooves are arranged between the upper and lower parts inside the insertion blocks. Upper screw holes are respectively arranged at the tops of the front and rear ends of the right side of the rubber cushion plate, and positioning pieces are fixed at the tops of the upper screw holes. Lower screw holes are respectively arranged at the bottoms of the front and rear ends of the right side of the rubber cushion plate. Round holes are respectively arranged at the left front and right rear inside the frosted bottom pad. Bolts are longitudinally inserted into the upper screw holes. Slots are respectively arranged at the front and rear ends inside the right side of the rubber cushion plate.

[0010] Preferably, the upper screw holes, threaded grooves, lower screw holes and round holes are arranged in concentric circles, and the bolts penetrate between the upper screw holes, threaded grooves, lower screw holes and round holes.

[0011] Preferably, the top of the bolt is attached to the surface of the positioning piece, and the diameter of the bolt is smaller than that of the positioning piece.

[0012] Preferably, a left air chamber is arranged on the left side inside the rubber cushion plate, a central air chamber is arranged at the center inside the rubber cushion plate, a right air chamber is arranged on the right side inside the rubber cushion plate, and two groups of through grooves are arranged between the left air chamber, the central air chamber and the right air chamber.

[0013] Preferably, the left air chamber, the central air chamber and the right air chamber have the same space volume, and the left air chamber, the central air chamber and the right air chamber are at the same horizontal plane.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: The wear-resistant railway rubber damping cushion plate not only realizes the enhancement of the anti-wear ability, realizes the convenient splicing and assembly, but also realizes the rapid restoration of the original shape of the cushion plate;

[0015] (1) By attaching frosted stickers to the surfaces of the raised rubber edges, four groups of raised rubber edges on the top of the rubber cushion plate are all attached with frosted stickers, which can improve the frictional resistance when contacting the sleeper or the track. Support sleeves are fixed in the rectangular chambers between adjacent raised rubber edges. The top arc-shaped strip overlaps the raised rubber edges on both sides, and the hollow sleeves on both sides are used as supports. Even if the cushion plate is squeezed from above, it can reset the support sleeve and the arc-shaped strip again after pressing the hollow sleeve chambers on both sides, which not only improves the wear resistance, but also can quickly restore the surface structure shape;
