Reinforced integral crossing plate for railway special line and line rail fixing device

Abstract

The invention provides a reinforced integral crossing plate for a railway special line and a line rail fixing device. The reinforced integral crossing plate comprises a reinforced concrete crossing plate body, a concrete bridge sleeper pre-buried in the reinforced concrete crossing plate body and a plurality of pieces of corner protection angle steel used for protecting the stress portion of the upper portion of the reinforced concrete crossing plate body. The reinforced concrete crossing plate, the concrete bridge sleeper and the corner protection angle steel are integrally formed in a pouring mode, and the pavement of the reinforced concrete crossing plate is provided with two openings which are the same as sleeper rail bearing grooves in size and used for installing steel rails. According to the reinforced integral crossing plate for the railway special line, the crossing plate is of an integrally-formed structure, hoisting is convenient, stress is uniform, strength is high, maintenance is not needed, potential safety hazards existing in a level crossing of a busy section of a vehicle of the railway special line are avoided, and the running quality of the line is improved. The invention further provides a line rail fixing device comprising the reinforced integral crossing plate for the railway special line, and the line rail fixing device has the technical effects.

Description

technical field [0001] The invention relates to the technical field of railway construction, and more specifically relates to a reinforced integral crossing plate for special railway lines. The present invention also relates to a line rail fixing device comprising the above-mentioned reinforced integral crossing plate for special railway lines. Background technique [0002] With the rapid development of economic construction, the phenomenon of "large traffic and seriously overloaded roads" of automobiles is becoming more and more severe, and the quality requirements for railway crossings and railway level passages are getting higher and higher. A large number of flat aisles exist in special railway lines and railway freight yards, and have always been a weak link in the safety management of railway equipment. [0003] At present, most of the sleepers and pavements of railway crossings and railway level passages on the market are laid separately. However, a variety of disea...

AI Technical Summary

Problems solved by technology

However, a variety of diseases have occurred at railway crossings. For example, there are often problems such as hidden breakage of sleepers, broken concrete paving slabs, warping of rubber paving slabs, rail-rail connection or breaking and warping at railway crossings. In addition, most crossings under The road bed and subgrade bed often have problems of poor drainage, resulting in muddying diseases. Due to the damage of the road surface on both sides of the crossing, the impact of passing vehicles on the rubber crossing board and the line is aggravated, resulting in serious safety hazards in railways and highways, and daily inspection and maintenance Such diseases cannot be cured by operation, which seriously threatens the safety of railways and life safety
