[0024] The present invention will be further described below with reference to specific embodiments in conjunction with the accompanying drawings: like Figures 1-8 As shown: A shock-absorbing isolation tube structure for railway track plates, including a fan-shaped rubber plate 1 connected end to end, the side of the fan-shaped rubber plate 1 is provided with an anti-slip reinforcement part 2, the anti-slip reinforcement part 2 is arranged outward, and the anti-slip reinforcement part 2 is provided with a partition groove 3. The present invention forms a shock-absorbing isolation tube by connecting the end to the tail of the fan-shaped rubber plate. For traditional one-piece molded shock-absorbing isolation tubes, the traditional ones can only be molded individually and can only be vulcanized one by one. The present invention can be molded and vulcanized in one time, which can shorten the production time and has low production cost. Specifically, the fan-shaped rubber plate can be connected together by rivets, or connected by glue. The designed partition groove is for better extension of the anti-slip reinforcement part on the fan-shaped rubber plate to avoid breakage of the anti-slip reinforcement part. When the fan-shaped rubber plate is surrounded by a shock-absorbing isolation tube, the anti-slip reinforcement part is located on the outside of the shock-absorbing isolation tube.
[0025] In the above-mentioned shock-absorbing isolation tube structure for railway track plates, the anti-slip reinforcement part 2 is a strip-shaped structure, and the width of the partition groove 3 is 40-60 mm. Specifically, this is to further avoid the anti-slip reinforcement part from breaking.
[0026] In the above-mentioned shock-absorbing isolation tube structure for railway track plates, the anti-slip reinforcement part 2 is an isosceles trapezoidal structure, the distance between the top surface of the anti-slip reinforcement part 2 and the side surface of the fan-shaped rubber plate 1 is 2-4 mm, and the thickness of the fan-shaped rubber plate 1 is 6-10 mm. Specifically, this is to increase the anti-slip effect.
[0027] In the above-mentioned shock-absorbing isolation tube structure for railway track slabs, a transition slope 4 is provided between the anti-slip reinforcement portion 2 and the partition groove 3 in order to further prevent the anti-slip reinforcement portion from breaking.
[0028] In the above-mentioned shock-absorbing isolation tube structure for railway track plates, three partition grooves 3 are provided on the anti-slip reinforcement part 2. Specifically, at least two anti-slip reinforcement parts are provided on the shock-absorbing isolation tube, and three partition grooves are provided on both anti-slip reinforcement parts. This can improve the anti-slip performance while avoiding the breakage of the anti-slip reinforcement part.
[0029] A method for manufacturing a vibration-damping isolation tube structure for a railway track slab, the method comprising the following steps: S1, open refining: put rubber and auxiliary materials into the open refining mill for refining; S2, blanking: squeeze the rubber in the mixing mill into strips; S3, cutting: cutting the strip-shaped rubber into fan-shaped structure pieces A; S4, vulcanization: placing the fan-shaped structure piece A into a vulcanization mold for vulcanization to form a fan-shaped structure piece B; S5. Surrounding docking: connect the end to end of the fan-shaped structure piece B to form a cone-shaped structure.
[0030] Specifically, in S1, the rubber is first placed in an open mill for refining at a temperature of 50°C-60°C for 3 minutes, and then the auxiliary materials are placed in the open mill for further processing at a temperature of 50°C-60°C for 2-3 minutes; in S2, the thickness of the rubber strips is 10mm; and in S4, the vulcanization time of the vulcanization mold is 5-6 minutes, the vulcanization temperature is between 140°C-160°C, and the pressure is 280-320mpa. It should be noted that the above-mentioned rubber and auxiliary materials are all existing technologies, and the vulcanization mold has a core and a cavity, a plurality of fan-shaped accommodating grooves 5 are provided in the cavity, and a plurality of anti-slip reinforcement strip forming grooves 6 are provided in the core.
