Abstract

The utility model discloses a novel explosion-proof elevator control cabinet. The novel explosion-proof elevator cabinet comprises a control cabinet box body and a control cabinet door, wherein the control cabinet box body is internally and fixedly provided with multiple layers of separating plates, the separating plates are provided with a plurality of electrical sealing boxes, the bottom part of the back surface of the control cabinet box body is provided with a prepared hole, the prepared hole is internally and fixedly provided with a terminal bar, the control cabinet box body and the control cabinet door are connected by adopting bolts, sealing adhesive tapes are adhered to seams between the control cabinet box body and the control cabinet door, the control cabinet door is provided with an upper observation window and a lower observation window, the upper observation window and the lower observation window are fixedly provided with transparent glass, and sealing adhesive tapes are adhered to seams between the control cabinet door and the transparent glass. According to the novel explosion-proof elevator control cabinet disclosed by the utility model, through adopting a way of independently sealing electrical components in the elevator control cabinet by the electrical sealing boxes and sealing a shell of the elevator control cabinet, explosion which is caused as outside flammable and explosive gas is in contact with electric sparks generated by the electrical components can be prevented from happening, the structure is simple, and the explosion-proof performance is reliable.

Description

A kind of novel flame proof elevator control cabinet

technical field:

The utility model relates to lift facility field, particularly a kind of novel flame proof elevator control cabinet.

background technology:

Explosion-proof lift system, in the process of operation, exists the ignition source that may light explosive gas mixture to mainly contain: electric spark, electrostatic spark, arc spark, bunch discharge etc. aspect electric.As the electric wirings such as various relays, contactless switch, safety switch (limit switch, limit switch, emergency stop switch, mode switch etc.), hall buttons, electrical junction box, distribution box without protectors, ground connection, connecting to neutral device may cause these sparks, form ignition source.

Flame-proof type elevator control cabinet is a kind of anti-explosion product of intensity type, often be applicable to the explosion-proof of strong power system, its shell can bear the flammable mixtures that is penetrated into enclosure by any face of joint of shell or structure interval and not damage at internal explosion, and can not cause lighting of the outside explosive atmosphere being formed by a kind of, multiple gases or steam.

Existing flame-proof type elevator control cabinet is general only seals flame proof to shell, and the electric elements in control housing is all in the operation of working under naked state, in the situation that control housing body seal lost efficacy, has potential safety hazard.

utility model content:

The utility model provides a kind of novel flame proof elevator control cabinet, has solved existing potential safety hazard in prior art.

Technology solution of the present utility model is as follows:

A kind of novel flame proof elevator control cabinet, it includes control housing casing, control housing door, in described control housing casing, be fixed with multilayer insulating panel, on described dividing plate, be placed with several electric sealed boxes, described control housing box back surface bottom has preformed hole, described preformed hole place is fixed with connecting terminal block, described control housing casing and control housing door are with bolts, described control housing casing and control housing door seam are pasted with sealing joint strip, on described control housing door, have upper and lower two watch windows, clear glass is fixedly housed on described watch window, institute's control housing door and clear glass seam are pasted with sealing joint strip.

Further, described electric sealed box includes connection terminal, transparent case lid.Facilitate like this wiring of electric elements to be connected in control housing, facilitate staff to check the running condition of electric elements and equipment.

Further, between described dividing plate and control housing box back surface, leave space.Facilitate the electric elements wiring in electric sealed box to be connected on the connection terminal of control housing bottom.

Further, the seam sealant sealing between described connecting terminal block and preformed hole.Ensure control housing box body tightness.

The beneficial effects of the utility model are: independent sealed with electric sealed box by the electric elements in elevator control cabinet, to the mode of elevator control cabinet body seal processing, to prevent that extraneous flammable explosive gas from contacting and setting off an explosion with the electro spark that electrical equipment produces, simple in structure, explosion-proof performance is reliable, is applicable to industrial explosion-proof place.

brief description of the drawings:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is structural representation of the present utility model.

In figure: 1, control housing casing; 2, control housing door; 3, dividing plate; 4, electric sealed box; 5, connecting terminal block; 6, bolt; 7, sealing joint strip; 8, clear glass.

detailed description of the invention:

As Fig. 1, the novel flame proof elevator control cabinet of one shown in 2, it includes control housing casing 1, control housing door 2, in described control housing casing 1, be fixed with multilayer insulating panel 3, on described dividing plate 3, be placed with several electric sealed boxes 4, described control housing casing 1 bottom, the back side has preformed hole, described preformed hole place is fixed with connecting terminal block 5, described control housing casing 1 adopts bolt 6 to be connected with control housing door 2, described control housing casing 1 and control housing door 2 seams are pasted with sealing joint strip 7, on described control housing door 2, have upper and lower two watch windows, clear glass 8 is fixedly housed on described watch window, institute's control housing door 2 is pasted with sealing joint strip 7 with clear glass 8 seams.

Electric sealed box 4 includes connection terminal, transparent case lid, and electric sealed box 4 can adopt different size according to actual needs.

Between dividing plate 3 and control housing casing 1 back side, leave space.

Seam sealant sealing between connecting terminal block 5 and preformed hole.

Principle of work of the present utility model is: related elevator control electric elements is all installed in electric sealed box 4 independently, the wiring of electric elements is connected in control housing casing 1 by the connection terminal on electric sealed box 4, then is connected to outside by connecting terminal block 5.

The foregoing is only preferred embodiment of the present utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all should belong to the scope of the utility model protection.
