Description
Technical field
The present invention relates to track traffic component technology field, especially relate to a kind of overhead contact line rigid suspension system device.
Background technology
Existing overhead contact line is divided into rigid suspension OCS and rigid contact net.Rigid suspension system is held in bus duct by contact clip, and a kind of power supply of urban orbit traffic mode of stream got by locomotive from track top by pantograph.Rigid suspension system due to structure simple, easy for installation, maintenance workload is little, is widely applied in the city rail traffic of China.Meanwhile, along with the expansion of city size, for some suburban lines, improve the running velocity of vehicle, non-maintaining status maintenance becomes a reality needs.This safety for rigid suspension system, reliability propose requirements at the higher level.
Rigid suspension system relies on the gap between steady ear and bus duct to the change in displacement of the suitable line direction meeting bus duct and cause because of temperature traverse.Although this kind of connection mode is very ripe technically, on-the-spot operation feedback shows may occur catching phenomenon at sharp turn Chu Jibian Po Chu.And bus duct hitch point clamping stagnation may cause the faults such as such as Insulator detection.Meanwhile, be not quite similar the service life of rigid suspended each portioned product of contact system.As suspension apparatus adopts zincincation service life in 15 ~ 20 years, the service life of porcelain insulator was in 50 years, and the service life of silicon rubber insulator was in 15 ~ 20 years, and service life of wire clamp is also not quite similar due to material difference.
Namely say, the life-span coupling of current rigid suspension system product is unreasonable, connection mode may cause bus duct slip smoothness undesirable at some special sector, therefore be necessary to be optimized research to existing rigid suspended hang, improve hang, avoid catching phenomenon, improve total system service life, reduce maintenance load.
Summary of the invention
The object of this invention is to provide a kind of overhead contact line rigid suspension system device, it has and can prevent or reduce catching phenomenon, locomotive is well flowed, guarantees the feature of traffic safety.Further, it also has system comparatively reasonably feature in service life.
The technical solution adopted in the present invention is: overhead contact line rigid suspension system device, comprise: be fixed on the suspension apparatus on tunnel top, be fixed on the insulator on this suspension apparatus, be suspended to the bus duct on this insulator, and this bus duct bottom is fixed with contact wire, described insulator top is fixed on this suspension apparatus by screw, and this insulator bottom is provided with pestle hair style connector, simultaneously, this bus duct top is provided with draw-in groove, the cross section of this draw-in groove is opening up semi-surrounding type, and this connector is stuck in this draw-in groove after entering from one end of this draw-in groove.
The outside face of described connector or the inside face of draw-in groove are provided with wear-resisting bed course.
Described wear-resisting bed course is polytetrafluoroethylene.
Described suspension apparatus adopts steel construction piece, and scribbles anticorrosion coating through three grades of pot galvanize rear surfaces.
Described suspension apparatus adopts glass-reinforced plastic material preparation.
Described bus duct replaces with contact rail, and this draw-in groove is positioned at the top of this contact rail, and this contact wire is replaced with the stainless steel band being fixed on this contact rail bottom by compound or welding process.
The present invention is advantageously: can prevent or reduce catching phenomenon, locomotive well being flowed, guarantees traffic safety, and system is comparatively reasonable for service life.The component materials of overhead contact line rigid suspension system device of the present invention all adopts long-life material, ensure that whole system product reaches the same guarantee life-span, then can overallly safeguard, decrease the trouble of daily attention maintenance, and accomplished few maintenance, non-maintaining to greatly reduce the work capacity of operation maintenance in maintenance.Meanwhile, adopt the connector of pestle hair style to be connected with bus duct or contact rail, connector is met in draw-in groove can the requirements of 360 ° of rotations, effectively prevent the phenomenon that clamping stagnation appears in bus duct.Moreover, after employing contact rail replaces bus duct, bow net is seamlessly transitted, stablize and flowed, extend maintenance intervals further.

Detailed description of the invention
Embodiment 1
See shown in Fig. 1 and Fig. 2, overhead contact line rigid suspension system device, comprise: be fixed on the suspension apparatus 10 on tunnel top 100, the insulator 20 be fixed on this suspension apparatus 10, the bus duct 30 be suspended on this insulator 20, and this bus duct 30 bottom is fixed with contact wire 50.Certainly, this tunnel top 100 also can be support body.
Further say, this insulator 20 top is fixed on this suspension apparatus 10 by the screw of the models such as M16.This insulator 20 bottom is provided with pestle hair style connector 21.So-called pestle hair style refers to this connector 21 in being similar to spheroidicity.Meanwhile, this bus duct 30 top is provided with draw-in groove 60, and the cross section of this draw-in groove 60 is opening up semi-surrounding type, and this connector 21 is stuck in this draw-in groove 60 after entering from one end of this draw-in groove 60.Certainly, this draw-in groove 60 extends along the longitudinal direction of this bus duct 30.That is, the connection of this connector 21 and this draw-in groove 60 achieves the connection on this insulator 20 and this bus duct 30 top, and this connector 21 can realize 360 ° of rotations in this draw-in groove 60, effectively prevent or reduces catching phenomenon.
