Description
Technical field
The present invention relates to the city traffic field, specifically is a kind of the 3rd rail insulating support of underground railway track.
Background technology
At present, city underground adopts the third-rail current collection mode more, and promptly I-beam section of parallel laid is as the 3rd rail (contact rail) outside two rails, and the subway electric car passes through current-collecting device from third-rail current collection.
The unsettled setting of the 3rd rail, on the 3rd rail at a certain distance (as 4.5 meters) can be provided with the 3rd a rail insulating support that is used to suspend in midair fixing the 3rd rail.
Third rail insulated support of subway like Fig. 1, prior art shown in Figure 2 comprises base 101, insulator support 102 and insulation fastener 103; Described base 101 is fixed on the track foundation; Described insulator support 102 comprises a crossbeam 1021 and a vertical support plate 1022; Described vertical support plate 1022 is fixed on the madial wall 1011 of base 101; One end of described crossbeam 1021 is fixed on vertical support plate 1022 tops, and the other end of described crossbeam 1021 is provided with lower limit back plate 1023, and described crossbeam 1021, vertical support plate 1022 and lower limit back plate 1023 are one; Described insulation fastener 103 comprise a level to bearing cross beam 1031; One end of described bearing cross beam 1031 is fixed on the crossbeam 1021 through roughly being vertical screw 104, and described bearing cross beam 1031 is provided with crimping 1032 away from an end of insulator support 102, and the following inwall 1033 of described crimping 1032 is the inclined-plane; Described bearing cross beam 1031 is an one with crimping 1032, and described crimping 1032, lower limit back plate 1023 and bearing cross beam 1031 have constituted the chamber on ccontaining the 3rd rail 105 tops.
There is following defective in the third rail insulated support of subway of above prior art: after the 3rd rail laid completion, the top of the 3rd rail was contained in the chamber of the 3rd rail insulating support, at this moment; The deadweight of the 3rd rail is applied on crimping and the lower limit back plate with the form of pressure; Is applied to pressure on the lower limit back plate and is insulated carriage and passes to base, and the pressure direction that is applied to bead portion is the following inwall perpendicular to crimping that it has vertically passed to base by the insulation fastener of one through the insulation carriage to component; But also there is the component of a horizontal direction in the pressure that is applied to bead portion; And this component is passed to bearing cross beam from crimping, all carried at last by screw, and this level to component relatively roughly to be vertical screw be shearing; And the ability of screw carrying shearing is relatively poor; After a period of time, screw can get loose under the effect of component or is destroyed in level, causes the solid failure of this support to track; So the stability and the fastness of the 3rd rail insulating support are relatively poor, have potential safety hazard.
Summary of the invention
The technical matters that the present invention will solve is, provides a kind of stability and fastness good, stops the third rail insulated support of subway of potential safety hazard.
Technical solution of the present invention is; A kind of third rail insulated support of subway with following structure is provided; It comprises base and the insulator support that is fixed on the track foundation, and described insulator support comprises a crossbeam and a vertical support plate, and described vertical support plate is fixed on the madial wall of base; One end of described crossbeam is fixed on vertical support plate top; The other end of described crossbeam is provided with the lower limit back plate, and described crossbeam, vertical support plate and lower limit back plate are one, and the 3rd rail insulating support also comprises the insulation fastener in a trough of belt road; The following inwall of described conduit is the inclined-plane; Described insulator support also comprises a support beam, and described support beam and crossbeam and lower limit back plate are one, and described support beam is made up of bearing cross beam that is solidified as a whole and vertical connecting panel; The lower end of described vertical connecting panel is fixed on the end of crossbeam away from the vertical support plate; Described bearing cross beam stretches into away from an end of vertical support plate in the conduit of insulation fastener, described insulation fastener through level to screw retention at the end of bearing cross beam away from the vertical support plate, described lower limit back plate, bearing cross beam, vertical connecting panel and insulation fastener have constituted the chamber on ccontaining the 3rd rail top.
After adopting above structure, third rail insulated support of subway of the present invention compared with prior art has the following advantages:
After the 3rd rail laid completion, the top of the 3rd rail was contained in the chamber of the 3rd rail insulating support, at this moment; The deadweight of the 3rd rail is applied to the form of pressure on the following inwall and lower limit back plate of conduit of insulation fastener, be applied to pressure on the lower limit back plate and be insulated carriage and pass to base, and it is vertical with the following inwall of conduit to be applied to the direction of pressure of following inwall of conduit of the fastener that insulate; Its vertically to component through conduit on inwall shift to for the insulator support of one; Finally shift to base through carriage, level to component then carry by screw, and screw also be level to; So the time screw level of carrying become pulling force but not shearing to component; And screw carries the very capable of pulling force, and long-term use also is not easy to get loose or be destroyed, promptly this support to track fixedly be not easy lost efficacy; So the stability and the fastness of the 3rd rail insulating support are good, have broken off relations potential safety hazard.
As improvement; Inwall is parallel with following inwall on the conduit of described insulation fastener; Described bearing cross beam is provided with the parallel inclined-plane of last inwall with the conduit of the fastener that insulate away from an end of vertical support plate, and like this, the fitting process of this insulation fastener is convenient; The fastener that is about to insulate inserts along the 3rd rail Width and makes an end on the 3rd rail top and an end of bearing cross beam insert interior the getting final product of insulation fastener conduit, so the convenient laying installation of the 3rd rail; And; Because inwall on the conduit, inwall is all parallel away from the inclined-plane of an end of vertical support plate with bearing cross beam down; Most pressure that inwall receives under the conduit can be transferred on the inclined-plane of bearing cross beam of insulator support; So reduce level that screw receives significantly to component, further strengthened the stability and the fastness of the 3rd rail insulating support.
