Description

A vibration damping isolation cylinder structure for railway track slabs Technical Field

[0001] This utility model belongs to the technical field of railway track slab accessories, and specifically refers to a shock-absorbing isolation cylinder structure for railway track slabs. Background Technology

[0002] A track slab is a new type of rail substructure with a slab-like structure used to support and fix steel rails, distributing the load transmitted by the train through the rails to the base beneath the slab. The actual installation is as follows: Positioning holes are provided on the track slab, and a shock-absorbing isolation cylinder is fitted inside each hole. Cement grout enters the area beneath the track slab through the shock-absorbing isolation cylinder, solidifies, and forms the base beneath the slab. A shock-absorbing pad and geotextile are placed between the track slab and the base beneath it. Commercially available shock-absorbing isolation cylinders are integrally molded structures, which are difficult to manufacture, have high manufacturing costs, and slow production speeds. Summary of the Invention

[0003] The purpose of this invention is to provide a shock-absorbing isolation cylinder structure for railway track slabs that is simple in structure, easy to manufacture, relatively low in production cost, and fast in production speed.

[0004] The purpose of this utility model is achieved as follows:

[0005] A shock-absorbing isolation cylinder structure for railway track slabs includes fan-shaped rubber plates connected end to end. The side of the fan-shaped rubber plates is provided with anti-slip reinforcement, which is arranged outward and has a partition groove.

[0006] In the above-mentioned shock-absorbing isolation cylinder structure for railway track slabs, the anti-slip reinforcement is a strip-shaped structure.

[0007] In the above-mentioned shock-absorbing isolation cylinder structure for railway track slabs, the width of the isolation groove is 40-60mm.

[0008] In the above-mentioned shock-absorbing isolation cylinder structure for railway track slabs, the anti-slip reinforcement is an isosceles trapezoidal structure.

[0009] In the above-mentioned shock-absorbing isolation cylinder structure for railway track slabs, the distance between the top surface of the anti-slip reinforcement and the side surface of the fan-shaped rubber plate is 2-4mm.

[0010] In the above-mentioned shock-absorbing isolation cylinder structure for railway track slabs, the thickness of the fan-shaped rubber sheet is 6-10mm.

[0011] In the above-mentioned shock-absorbing isolation cylinder structure for railway track slabs, a transition slope is provided between the anti-slip reinforcement and the partition groove.

[0012] In the aforementioned shock-absorbing isolation cylinder structure for railway track slabs, three partition grooves are provided on the anti-slip reinforcement.

[0013] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0014] This invention forms a shock-absorbing isolation cylinder by connecting the ends of fan-shaped rubber sheets. Compared with traditional one-piece molded shock-absorbing isolation cylinders, which can only be molded individually and vulcanized one by one, this invention can be molded and vulcanized multiple at once, which can shorten the production time and reduce the production cost.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] As shown in Figures 1-5: A shock-absorbing isolation cylinder structure for railway track slabs includes fan-shaped rubber plates 1 joined end to end. Anti-slip reinforcement 2 is provided on the side of the fan-shaped rubber plates 1, with the anti-slip reinforcement 2 facing outwards and having a partition groove 3. This invention forms a shock-absorbing isolation cylinder by connecting the fan-shaped rubber plates end to end. Compared to traditional one-piece molded shock-absorbing isolation cylinders, which can only be molded individually and vulcanized one at a time, this invention can mold and vulcanize multiple cylinders at once, shortening production time and reducing production costs. Specifically, the fan-shaped rubber plates can be connected end to end by rivets or by glue. The partition groove is designed to allow the anti-slip reinforcement on the fan-shaped rubber plates to extend better and prevent breakage. When the fan-shaped rubber plates form a shock-absorbing isolation cylinder, the anti-slip reinforcement is located on the outside of the shock-absorbing isolation cylinder.

[0023] In the above-mentioned shock-absorbing isolation cylinder structure for railway track slabs, the anti-slip reinforcement 2 is a strip structure, and the groove width of the partition groove 3 is 40-60mm. Specifically, this is to further prevent the anti-slip reinforcement from breaking.

[0024] In the above-mentioned shock-absorbing isolation cylinder structure for railway track slabs, the anti-slip reinforcement 2 is an isosceles trapezoidal structure, the distance between the top surface of the anti-slip reinforcement 2 and the side surface of the fan-shaped rubber plate 1 is 2-4mm, and the thickness of the fan-shaped rubber plate 1 is 6-10mm. Specifically, this is to increase the anti-slip effect.

[0025] In the above-mentioned shock-absorbing isolation cylinder structure for railway track slabs, a transition slope 4 is provided between the anti-slip reinforcement 2 and the partition groove 3, in order to further prevent the anti-slip reinforcement from breaking.

[0026] In the above-mentioned shock-absorbing isolation cylinder structure for railway track slabs, the anti-slip reinforcement 2 is provided with three isolation grooves 3. Specifically, the shock-absorbing isolation cylinder is provided with at least two anti-slip reinforcements, and each of the two anti-slip reinforcements is provided with three isolation grooves. This can improve the anti-slip performance and also prevent the anti-slip reinforcements from breaking.

[0027] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
