Description
Technical field
The utility model relates to the safety facilities field of subway, particularly relates to a kind of insulation system of platform screen door body.
Background technology
Along with China's expanding economy, subway construction is carried out in each city successively, and subway alleviates road traffic pressure, improves the passenger flow volume of conveying, also saves the time of people while hoisting speed.At subway platform, in order to avoid due to crowded and cause passenger to fall down platform, generally all the shielded gate supporting with subway vehicle door be set on platform, so both ensure passenger safety, facilitate again the management of passenger getting on/off, also save air-conditioning expense.
<< metro design code >> (GB50517-2013) 26.5.7 article regulation:
Shielded gate (safety door) and railway car should keep equipotential, when with rail have connect demand time, equipotential requires to meet the following requirements:
1. shielded gate (safety door) and rail should adopt single-point equipotential link, and Men Tiyu rail connects isopotential electrical resistance should not be greater than 0.4 Ω;
2. the palp shielded gate of human body (safety door) hard ware should insulate with station structure under normal circumstances, and the insulation resistance between Men Tiyu station structure should not be less than 0.5M Ω.Every side shielded gate (safety door) keeps overall equipotential.
Therefore shielding every body must be done to insulate with station structure and arrange, existing set-up mode is used as insulation protection by installing insulating pad and insulation sleeve 4 between shielding every body column 3 as shown in Figure 1 and shielded gate bearing 2, shielded gate bearing 2 is fixed by standing screw 7 with station civil engineering structure 1, shielded gate bearing 2 is metals, station civil engineering structure 1 is cement concrete, both are conductive material, arrange so Men Tiyu station structure junction remains conduction, when some insulating mats or insulation sleeve 4 lost efficacy because of damage or the factor such as dust stratification or humidity, namely whole door body insulation lost efficacy, search failpoint very difficult.Just because of this, China built subway line shielding every body insulate most out of reach code requirement, have a strong impact on passenger safety, failure of insulation causes again reinforcing bar in stray current corrosion door body metal and platform structure, have a strong impact on shielding every body and platform structure safety, shorten the service life of shielding every body and station structure.Because shielded gate failure of insulation worries passenger safety again, a lot of subway owner have to paste transparent insulating film or brush insulated paint on shielding every body stainless steel door body, helplessly does some remedial measuress.Therefore, need to seek a kind of shielding every body insulation mode of easy, dependable performance, long service life.

Attached number in the figure: 1-station civil engineering structure, 2-shielded gate metal support, 3-shields every body column, 4-shielded gate insulation sleeve and insulating mat, 5-hole, 6-insulating tube, 7-standing screw, 8-insulating barrier.
Detailed description of the invention
Below embodiment of the present utility model is elaborated.It is emphasized that following explanation is only exemplary, instead of in order to limit scope of the present utility model and application thereof.
Consult Fig. 1, in one embodiment, a kind of platform screen door body insulating structure, arranges integral insulation in the inside and surface shielding every body and civil engineering structure junction, station.This insulation system can specifically be formed according to following setting.On the beams of concrete/plate of civil engineering structure 1 AT STATION, according to the installation site of stock rail absolute altitude and shielding every body support position determination standing screw, thus the position of perforate can be determined.On position of opening, penetrating hole 5 dug out by machinery, and the aperture of hole 5 is greater than the diameter of standing screw 7.Installing insulating sleeve pipe 6 in hole 5.The concrete topping of the front be greater than on the beam of shielding every body column 3 with the station civil engineering structure 1 of shielded gate metal support 2 area of conter of station civil engineering structure 1 junction, plate and reverse side forms insulating barrier 8, the main component of its material is preferably epoxy resin or other has the High molecular material of electrical insulation capability, more preferably, wherein can fill quartz sand powder and non-conductive fibre cloth, to strengthen the mechanical properties such as resistance to compression, bending resistance, shearing resistance, it is made to possess enough mechanical strengths to support upper load.Insulating barrier 8 be arranged on insulating tube 6 in hole 5 and form the entirety of seamless one, the Polymer of material is close-coupled by chemical bond.Shielded gate metal support 2 is placed on this insulating barrier 8, by standing screw 7 fixed mask door metal support 2.By the standing screw 7 between shielded gate metal support 2 and station civil engineering structure 1, insert in the insulating tube 6 in hole 5.Moistureproof dust-proof process is done on insulating barrier 8 surface, and namely adopt organic fluorinated silicone spray treatment surface of insulating layer, its surface is kept dry, dust stratification or dust stratification are not easy to cleaning.In hole 5, also insulating tube 6 can not be installed, and directly standing screw 7 is fixed in the middle of hole by filled high polymer liquid resin.After arranging by above-mentioned insulation system, the insulating mounting mode that traditional shielded gate adopts, the insulating mat namely installed between shielding every body column 3 and shielded gate metal support 2 and insulation sleeve 4 can be cancelled.
Consult Fig. 2, in another kind of embodiment, the hole 5 that station civil engineering structure is offered also can for non through hole, and standing screw 7 to be inserted in hole 5 and to fix with one-sided nut, but not through the other end of hole 5.

According to the insulation system of the utility model embodiment, after shielded gate failure of insulation, its electric current all will flow into the earth by civil engineering structure connection, Men Tiyu station, can direct chopping current path so directly arrange insulation in this position, a body insulating reliability is greatly improved, easy to implement, be convenient to detect, for ease of maintenaince.Connecting screw rod does not contact with civil engineering structure, and door body metal support both firmly supported by insulating barrier, metal support was separated with station structure again, thus all positions that a body hard ware is connected with station structure all form electric insulating isolates.
The detailed process of the insulation system of constructed embodiment can comprise the following steps:
On the beam of A, AT STATION civil engineering structure 1, plate, hole 5 dug by machinery;
B, in hole 5 installing insulating sleeve pipe 6;
C, insert the standing screw 7 between shielded gate metal support 2 and station civil engineering structure 1 in hole 5 insulating tube 6;
D, on the concrete topping being greater than shielding every body column 3 and front on the plane of structure of shielded gate metal support 2 area of conter of station civil engineering structure 1 junction and opposite, make insulating barrier 8, shielded gate metal support 2 is placed on this insulating barrier 8, is fixed by standing screw 7; Insulating barrier 8 and insulating tube 6 in hole 5 are connected by chemical bond and form seamless entirety.
Moistureproof dust-proof process is carried out by surface sprayings such as spraying organic fluorinated silicones in E, insulating barrier 8 surface.
In addition, in hole 5, also insulating tube 6 can not be installed, and direct filled high polymer liquid resin, so that standing screw 7 is fixed in the middle of hole.
Above content combines concrete/preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; its embodiment that can also describe these makes some substituting or modification, and these substitute or variant all should be considered as belonging to protection domain of the present utility model.
