Abstract
The utility model discloses an insulating board for a turnout and a turnout insulating structure. The turnout insulating structure comprises a steel rail, joint clamping plates arranged on two sides of a rail web at a connecting end of the steel rail, an iron chair for fixing the rail bottom of the steel rail and an elastic bar, wherein the insulating board for the turnout is arranged between the iron chair, and the elastic bar,as well as between one joint clamping plate and the rail bottom; the insulating board for the turnout comprises an L-shaped body which is made of an insulating material and consists of a vertical side and a transverse side; the transverse side is downwards inclined to form an included angle with a horizontal plane; an arc part formed by transition of an edge from the vertical side to the transverse side is arranged at one end of the body, wherein the edge is parallel to the vertical side; the vertical side and the arc part are attached to the joint clamping plates; and the transverse side is attached to the rail bottom. The insulating board for the turnout and the turnout insulating structure disclosed by the utility model, have the advantages that firstly, the insulating performance of the rail is ensured, the insulating reliability is enhanced and the service life of the insulating structure is prolonged; and secondly, during construction, the polishing of parts is avoided, and thus the workload is reduced.
Description
Technical field
The utility model belongs to the track equipment, is specifically related to a kind of track switch with insulating slab and track switch insulation system.
Background technology
In the seam track circuit was arranged, two one steel rails 1 or rail 1 docked with the manganese fork, and be generally through joint bar 2 being set in web of the rail both sides and utilizing high-strength bolt pair 3 that joint bar 2 fastening modes are realized, as shown in Figure 5.Fixedly the flange of rail 7 being stuck on the sleeper 8 with iron chair 5 through spring 4 of rail 1 realizes.Because rail 1 is with the function of transmitting signal, according to the setting of railway signal, some joint need carry out insulation processing, and 4 of rail 1 and iron chair 5 and springs can not conductings.But because structural limitations, it is very little with the spacing of clamping plate 2 that spring 4 is withheld at this place, after spring 4 is installed, probably causes joint bar 2 to contact with spring 4, the conducting phenomenon occurs, thereby cause signal disorderly.Settling mode in the past is divided into two kinds, and is a kind of for the reconditioning joint bar or the rail grinding web of the rail, makes clamping plate strengthen and separate apart from the distance of spring; Another kind of mode is for to add insulator cap at the two ends place of spring.
The utility model content
The purpose of the utility model is exactly to the problem of prior art existence a kind of easy construction to be provided, and the track switch that guarantees insulating properties is with insulating slab and track switch insulation system.
Realize that the technical scheme that above-mentioned utility model order adopts is:
The track switch of the utility model is used insulating slab; Comprise the L-shaped body that constitutes by vertical edge and horizontal edge processed by insulation materials; Described horizontal edge is downward-sloping to have angle with horizontal plane, and described body has the curved portions that formed to the edge transition parallel with vertical edge of horizontal edge by vertical edge at the one of which end.
The track switch insulation system of the utility model comprises rail, is located at the joint bar of rail link web of the rail both sides, iron chair and the spring that the flange of rail of rail is fixing, between said iron chair and spring and the joint bar and the flange of rail, is provided with track switch and uses insulating slab; Said track switch is used insulating slab; Comprise the L-shaped body that constitutes by vertical edge and horizontal edge processed by insulation materials; Described horizontal edge is downward-sloping to have angle with horizontal plane, and described body has the curved portions that formed to the edge transition parallel with vertical edge of horizontal edge by vertical edge at the one of which end; Said vertical edge and curved portions and joint bar are fitted, and the horizontal edge and the flange of rail are fitted.
Said track switch bonds together with the joint bar and the flange of rail respectively through bonding agent with the vertical edge and the horizontal edge of insulating slab.
The utility model compared with prior art has the following advantages:
(1) guarantee the insulating properties of track, the reliability of reinforced insulation prolongs life-span of insulation system;
When (2) constructing, the component of need not polishing alleviate workload.
