Embedded-sleeve-type integral molding mould for ballastless turnout slabs

Abstract

The invention relates to an embedded-sleeve-type molding mould for ballastless turnout slabs for rapid transit railway special line for passengers, which consists of a molding mould, a coaming assembly, pouring hole assemblies, a compressing assembly and a rack system, wherein the coaming assembly encircles the periphery of the molding mould to form a rectangular frame, the molding mould consistsof three foundation plates and a groove assembly, a plurality of groove assemblies are distributed on each foundation plate, and the pouring hole assemblies are respectively arranged on the foundation plates. The embedded-sleeve-type molding mould has the advantages that the adoption of the form of splicing the foundation plates is favorable for solving the problems of large processing difficultydue to overlarge foundation plates and processing equipment scarcity; the adoption of the structure of splicing the foundation plates and the groove assembly is favorable for eliminating the difficulty in structural design of rail bearing platform and flowing water slope of the turnout slab and solving the problem on shape difference of turnout slabs on side strand side; the groove assembly is used for forming a rail bearing platform top so that left and right open turnout slabs can share the groove assembly; and the advantages of stable and reliable structure, proper strength, high positioning precision of embedded sleeves, high planeness of the rail bearing platform, convenience for dismounting and strong interchangeability are achieved.

Description

technical field [0001] The invention relates to a pre-embedded bushing type ballastless turnout plate forming die for high-speed railway passenger dedicated lines, belonging to the field of turnout plate forming die manufacturing. Background technique [0002] The 350km / h passenger-dedicated railway turnout is a key part of the high-speed railway, and the overall ballastless turnout plate is the basis for the installation and laying of the turnout. At present, there is no mature design of the 350km / h passenger-dedicated railway turnout plate at home and abroad. Contents of the invention [0003] Design purpose: To design an integral forming mold for pre-buried casing type ballastless turnout plate for passenger-only turnouts, which not only fully meets the precision requirements of passenger-only ballastless turnout plates, but also has the advantages of simple structure, low processing cost, good rigidity and light weight. 1. A pre-embedded casing type ballastless turnout...
