Abstract
The utility model relates to a tread device of a metro platform screen door, which comprises a tread base, a tread panel, a screw perpendicularly fixed on the inner surface of the tread panel 2 via stud welding, and an insulating bush 4 sleeved on the screw 3. The tread base 1 is meshed with the screw 3 through a nut 5 to realize fixed installation of the tread base 1 and the tread panel 2, and thereby the tread panel 2, the nut 5 and the screw 3 are electrically insulated from the tread base 1 through the insulating bush 4. As the insulating device between the tread panel and the tread base is disposed in the utility model, namely an insulating coating and the insulating bush are utilized to insulate a tread and the tread base from each other, thereby achieving the effect of whole surface insulation, and simultaneously the tread and the tread base are integrally connected through the stud welding screw which is sleeved by the insulating sleeve, thereby guaranteeing the force strength and uniform stress of the tread, and further achieving reliable insulation between a platform screen door system and a lower support system.
Description
Technical field
The utility model relates to subway shield door system, is specifically related to a kind of subway shield door step plate device.
Background technology
Owing to reason on the safety, subway shield door system all needs and other system's electrical isolation of subway, therefore need the failure-free insulating mechanism to guarantee its non-conductive reliability, though subway shield door from many aspects the multi-section position designed insulation system, for example, the employing steel superstructure that has and the insulation of civil engineering, many places insulation measures such as lower support system and the insulation of step plate base and shielding every body and platform insulation and the place's insulation of end door, though but still have many case histories to take insulation measures so far, as bottom support system insulation sleeve point insulating, because insulating surfaces is little, insulation effect is also bad, and the construction aspect is also pretty troublesome, promptly screen door and lower support are not insulated and consider as a whole, therefore, processing, install, safeguard all very inconveniently, insulating power are also unreliable.
The utility model content
The technical problems to be solved in the utility model is to overcome the deficiency of prior art insulation mode, more effectively insulate, avoids occurring metallic material and destroys the non-conductive situation because of a variety of causes direct contact.
The technical scheme that the utility model provides is, constructs a kind of subway shield door step plate device, comprises step plate base and step plate panel, it is characterized in that, is provided with between step plate base 1 and the step plate panel 2 and makes the insulator arrangement that is electrically insulated from each other.
In above-mentioned subway shield door step plate device, comprise the screw 3 that is vertically fixed on step plate panel 2 inner surfaces in kind of weldering mode, described insulator arrangement comprises the insulation sleeve 4 that is enclosed within on the screw 3, described step plate base 1 makes the panel 2 of marking time, nut 5, screw 3 by insulation sleeve 4 and step plate base 1 electrical isolation by nut 5 and the fastening installation of screw 3 engagement realization step plate bases 1 with step plate panel 2.
In above-mentioned subway shield door step plate device, described insulator arrangement also comprises the insulating barrier 6 that is arranged on step plate panel 2 inner surfaces.
In above-mentioned subway shield door step plate device, described insulating barrier 6 is insulation material layer or insulation enamelled coating.
Implement the subway shield door step plate device that the utility model provides, owing to be provided with the insulator arrangement between subway shield door system step plate panel and the step plate base, promptly utilize insulating coating and insulation sleeve, make the insulation of step plate and step plate base, reach whole insulation effect, step plate and step plate base are coupled as one by kind of a weldering screw simultaneously, plant the weldering screw and be with insulation sleeve, guaranteed step plate be subjected to force intensity and stressed evenly, thereby reach reliable insulation between screen door and lower support system.Owing to solve the Insulation Problems of subway shield door system and support system well, have simple in structure, processing, install, safeguard all very convenient and insulating power failure-free advantage compared with prior art, solved the long-standing insulation difficult problem of screen door.
Description of drawings
Fig. 1 is the structural representation of the utility model subway shield door step plate device embodiment.
The specific embodiment
As shown in Figure 1, the utility model subway shield door step plate device comprises step plate panel 2 and step plate base 1, is provided with insulator arrangement therebetween, and this insulator arrangement mainly comprises insulation sleeve 4 and insulating barrier 6.Step plate panel 2 is connected by kind of a weldering screw 3 with step plate base 1, and insulation sleeve 4 is enclosed within on the screw 3, and insulating barrier 6 is located at the reverse side of step plate panel 2, can be insulating coating, also can be heat insulating lamina.
Owing to take to spray insulating coating from step plate panel and step plate base contact position, the insulation area is big, insulation sleeve is installed in the fixed connection place simultaneously, thereby accomplish by original point insulating,, change the compound inslation of point of the present utility model, face combination into as bottom support system insulation sleeve point insulating, thereby guaranteed insulation effect, simultaneously, simplify insulating mechanism, reduced cost.
