Description
Technical field
The present invention relates to subway shield door, refer to equipotential connection device for slide door in a kind of subway shield door system especially.
Background technology
Along with urban light rail and subway in each metropolitan popularization and application, subway shield door and safety door system also progressively are used widely.Subway shield door and safety door system should play buffer action, satisfy safety requirements, satisfy requirement attractive in appearance again.
Owing to have potential difference between the metal parts on subway shield door and emergency exit metal parts and the train, for guaranteeing passenger and staff's safety, need to keep equipotential to be connected between the metal parts on all metal partss of subway shield door that passenger and staff are easy to touch or emergency exit and the train.Generally subway shield door or emergency exit are insulated with civil engineering structure when subway shield door or safety door system master-plan by insulation rubber cushion etc.For the standing part in subway shield door or the safety door system, with cable each several part fixed gate body is connected respectively to equipotential and connects copper bar, connect the copper bar two ends in equipotential and be connected with rail of subway, can form the equipotential of fixed gate body and rail and train by lead.
Sliding door in subway shield door or the emergency exit is moving-member in the course of the work; guarantee that sliding door keeps equipotential with rail and train in the course of the work always, former design generally drives stube cable by carbon brush or drag chain and realizes that sliding door is connected effective connection of copper bar with equipotential.Yet, realize that by carbon brush sliding door is connected effective connection of copper bar with equipotential shortcoming is can produce dust in carbon brush is connected the process of copper bar mill sassafras with equipotential, and carbon brush being worn easily, useful life is too short.Another kind method is to adopt drag chain to drive stube cable to realize that sliding door is connected effective connection of copper bar with equipotential, this method occupation space is big, and drag chain and stube cable (generally are designed to the every day continuous operating time and are no less than 20h, every 120s sliding door switch each 1 time because too frequently motion, year-round operation 365 days), drag chain and stube cable all occur aging easily, influence useful life, and have potential safety hazard.
Summary of the invention
In view of this, the purpose of this invention is to provide a kind of equipotential connection device for slide door of subway shielding door system, this device provides a kind of electric conductivity good and have enough flexible steel brush, realizes that effectively sliding door is connected with the equipotential of rail and train in the subway shield door system.
The technical scheme that the present invention proposes is a kind of equipotential connection device for slide door of subway shielding door system of design, and this device comprises: one is fixed on the equipotential copper bar of shielding every machine beam bottom, and these equipotential copper bar two ends are connected with rail of subway by lead; One usefulness metal bolts is fixedly mounted on the conduction steel brush support on the slide door suspension device; One steel brush, its matrix are fixedly mounted on the conduction steel brush support, and this steel brush and equipotential copper bar keep CONTACT WITH FRICTION.Described conduction steel brush is the good strong elasticity steel brush of electric conductivity.
Because the matrix of the special use conduction steel brush of the present invention's design is fixed on the suspension arrangement of sliding door by conduction steel brush support with metal bolts, slide door suspension device is connected with sliding door with metallic gasket by metal bolts, therefore, conduction steel brush and sliding door are in complete conducting state.When sliding door horizontally slipped, conduction steel brush and sliding door slided simultaneously, and the conduction steel brush is connected copper bar mill sassafras always and contacts with equipotential, and maintenance sliding door and rail and train also are in the equipotential state.
Compared with prior art, the subway equipotential connection device for slide door of the present invention's design has overcome the technical problem that exists in the prior art, has guaranteed the equipotential of slip every body and rail and train effectively, and is not only safe and reliable, and it is simple in structure, convenient for installation and maintenance.
Description of drawings
The present invention is described in detail below in conjunction with accompanying drawing and preferred embodiment, wherein:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the present invention is installed in the schematic diagram on the subway shield door.
Embodiment
As depicted in figs. 1 and 2, the aluminium alloy door's machine beam 6 that hangs sliding door is connected with screen door steel column 9 by connector and metal bolts, the line slideway 5 usefulness metal bolts of sliding door are fixed on aluminium alloy door's machine beam 6, sliding door 8 usefulness metal bolts are fixed on the suspension arrangement 3, and the sliding door change gear 7 of suspension arrangement slides along line slideway 5.The bottom of shielding every frame 6 is provided with equipotential copper bar 4 with metal bolts, and the two ends of this copper bar are connected with rail of subway by lead.One L shaped conduction steel brush support 1, its vertical edge is fixedly mounted on the slide door suspension device 3 with metal bolts, and a steel brush 2 is fixedly mounted on the bottom of conduction steel brush support, and this steel brush 2 keeps CONTACT WITH FRICTION with equipotential steel row 4.
Sliding door 8 is suspended on the line slideway 5 of sliding door, under the effect of drive unit (motor) and transmission device (belt, belt clamp, belt support, guide wheel etc.), can realize the reciprocating motion of sliding door along the line slideway 5 of sliding door.No matter sliding door remains static or is kept in motion, and can guarantee that all sliding door and equipotential copper bar are in conducting state.
The present invention keeps sliding door in subway shield door and the safety door system to be connected with equipotential between subway shield door system and underground railway track.This equipotential connected mode is as follows: conduction steel brush 2 is connected with sliding door 8 by bolt, conduction steel brush support 1, slide door suspension device 3 etc., equipotential connects copper bar 4 and is connected with door machine beam 6 by bolt, connect copper bar 4 two ends in equipotential and be connected with rail of subway, realize the equipotential of subway shield door system and rail and train thus by lead.
The present invention is a kind of novel subway shield door system equipotential connection technology that both satisfies, can finely satisfy the design of the equipotential functional requirement of subway shield door system and rail again, that the characteristics of its maximum are is simple in structure, requirements of installation space is little, can not produce harmful substances such as dust in the stable performance, use.
