Long-acting pressure-withstanding insulation steel angle cushion plate of turnout installation device

Abstract

The invention relates to the technical field of railway turnout transformation equipment installation, in particular to a long-acting pressure-withstanding insulation steel angle cushion plate of a turnout installation device. The long-acting pressure-withstanding insulation steel angle cushion plate of the turnout installation device is simple in structure, few accessories are needed on the whole, the theoretical service life is longer than 15 years under the normal state, and the long-acting pressure-withstanding insulation steel angle cushion plate is easy to repair and free of maintenance. To achieve the purposes, according to the technical scheme, the long-acting pressure-withstanding insulation steel angle cushion plate of the turnout installation device comprises an insulation bottom plate and a cushion plate body, wherein the insulation bottom plate is in a rectangular plate shape, a baffle perpendicular to the insulation bottom plate is fixedly arranged on the upper surface of the insulation bottom plate and divides the insulation bottom plate into a reinforced area and a fixing area in the left-right direction, the cushion plate body is fixed to the upper surface of the reinforced area and provided with die casting holes, the cushion plate body is fixedly connected with the reinforced area through the die casting holes, and two fixing holes are formed in the fixing area.

Description

technical field [0001] The invention relates to the technical field of railway turnout conversion equipment installation, in particular to a long-term pressure-resistant insulating angle steel backing plate for a turnout installation device. Background technique [0002] During the installation of railway turnout switching equipment, it is necessary to insulate the installation device of the turnout switching equipment and the rail to maintain the work of the track circuit. Most of the existing insulation methods are to install insulation boards on the outside of the iron parts, assemble the parts or coat a layer of insulating material on the outer surface of the iron parts for insulation and isolation. However, this kind of insulation isolation has great defects: on the one hand, there are gaps and insufficient creepage distances in the assembly of insulating plates and parts, resulting in low withstand voltage of the overall structure, and insulation failure after electric...
