Manufacturing process of streetcar rail plate

Abstract

The invention discloses a manufacturing process of a streetcar rail plate. The manufacturing process sequentially comprises die cleaning, die assembling, framework hoisting in, steel strand placing and tensioning, concrete pouring, steam maintaining, relaxation, demoulding and moistening maintenance. During die assembling, two lateral dies are mounted on a bottom die, a groove type inner die is mounted between the two lateral dies, an end die is then mounted, and the lateral dies, the inner die and the end die are connected to complete die assembling. The manufacturing process has the advantages that die assembling is completed by fixedly connecting the lateral die, the inner die and the end die which are mounted on the bottom die, a steel reinforcement framework is hoisted into the dies, the size requirements of various parts of rail ditches can be satisfied, high assembling precision is achieved, demoulding is facilitated, the manufacturing process is especially suitable for manufacturing steel rail embedded type streetcar rail plates, and high efficiency is achieved.

Description

technical field [0001] The invention relates to the field of railway engineering, in particular to a manufacturing process of a tramway track plate. Background technique [0002] Tram is a light-duty rail transit vehicle driven by electricity and running on the track. Since the vehicle does not emit exhaust gas, it is a pollution-free and environmentally friendly transportation tool. Embedded track slabs are increasingly used in existing trams. As a new type of ballastless track system, in urban rail transit, it has the advantages of beautiful appearance, small footprint, no impact on vehicle passability, and low cost. , is becoming more and more popular. When the track slab of this system is produced, the rail is generally embedded in the line structure, and the rail is locked by filling epoxy resin and other materials, so as to effectively reduce vibration and noise; but the rail embedded track slab X is currently Most of them are prefabricated in factories. Due to the h...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to overcome the prefabricated method of the existing embedded tramway track plate in the prior art, which easily leads to high requirements on the size of the embedded rail bearing groove and difficult processing, which directly leads to difficulty in the assembly accuracy of the track plate. Guarantee, track slab manufacturing difficulties above-mentioned deficiencies, provide tram track slab manufacturing process
