Problems solved by technology

[0003] The rail top rubber will age and crack during long-term use, resulting in poor buffering and waterproof insulation effects of the rail top rubber. At this time, it is necessary to shovel out the rail top rubber for re-laying
When the existing rail top glue is shoveled out, a corresponding spatula is required to shovel out the rail top glue along the track bit by bit, which makes it more troublesome to shovel out the rail top glue and needs to be improved

Embodiment 1

[0038] A tram rail top sealing layer structure, such as figure 1 As shown, the steel rail 1 is included, and the steel rail 1 is a grooved rail. The bottom of the rail 1 is provided with a rail bottom sheath 2, and both sides of the rail 1 are also provided with a wrapping material 3. The wrapping material 3 is usually a polymer material such as plastic or rubber. The upper end surface of the wrapping material 3 is lower than the upper end surface of the rail 1. set up. The outer side of the wrapping material 3 is also provided with a packing block 4, and the upper end surface of the packing block 4 near the side wall of the rail 1 is provided with a glue groove 5, and the bottom of the glue groove 5 is formed by splicing the packing block 4 with the wrapping material 3. The rubber groove 5 is filled with a rail top rubber strip 6, and the groove bottom of the rubber groove 5 is also provided with a pulling material strip 7, which is fixedly connected to the bottom end of the...

Embodiment 2

[0046] A laying process for a tram rail top sealing layer structure, comprising the following steps:

[0047] S1, the forming rubber groove 5, cuts the upper end surface of the steel rail 1 on both sides of the wrapped material 3 through a cutting machine. The filler between the rails 1 is broken, and the debris is cleaned to form the glue groove 5 .

[0048] S2, grinding the side wall of the rail 1, and destroying the oxide layer of the side wall of the rail 1 by sandpaper grinding, so that the roughness of the side wall of the rail 1 becomes larger, and then cleaning by blowing air.

[0049] S3, laying the tearing material strip 7, laying the tearing material strip 7 along the glue groove 5, laying the tearing material strip 7 in sequence, and marking the marking line at the joint of the steel rail 1 corresponding to the pulling material strip 7. Pull material bar 7 lower end faces and fix by the groove bottom of glue groove 5 every 300mm-500mm. The positioning strip 11 an...

Abstract

The invention relating to the field of tramcar rails discloses a tramcar rail top sealing layer structure. The structure comprises a steel rail; wrapping materials are further arranged on the two sides of the steel rail; a packing block is further arranged on the outer side of each wrapping material, a rubber groove is formed in the upper end face, close to the side wall of the steel rail, of eachpacking block and is filled with a rail top rubber strip; a pulling strip is further arranged at the groove bottom of each rubber groove and is fixedly connected to the end, close to the groove bottom of the rubber groove, of the rail top rubber strip, wherein the width of the pulling strip corresponds to that of the rubber groove. With the material pulling strips, the rail top rubber strips arenot directly bonded with the groove bottoms of the rubber grooves by separating the pulling strips and thus the rail top rubber strips only need to overcome the adhesive force on the two sides, so that the rail top rubber strips are shoveled out more conveniently.

Description

technical field [0001] The invention relates to the field of tram tracks, more specifically, it relates to a track top sealing layer structure of a tram. Background technique [0002] Such as the Chinese patent of patent No. CN107326773B, this patent discloses a kind of construction method of pouring rail roof glue at level crossings of trams, by respectively offering grooves on the asphalt pavement on both sides of the rail, after cleaning up the grooves, Apply adhesive on the side wall of the groove, then apply washed sand, and then apply primer on the bottom of the groove, then insert the partition and mold box, pour epoxy mortar, and then cover the film. After the mortar is dried in the sun, uncover the film and remove the mold box to form a groove, remove the partition to form an expansion joint, and then pour rail top glue into the groove until the top surface is basically flush with the rail top and the road surface. [0003] The rail top rubber will age and crack du...
