Description
Technical field
The present invention relates to explosion-proof technology field under the coal mine, specifically is a kind of flame-proof type control box.
Background technology
Have a large amount of combustible mediums under the coal mine, the factor that sets off an explosion is a lot, but mainly is spark and temperature that electric equipment is in operation and produces, and the control box that therefore is used for the down-hole must have explosion-proof.And be used at present that the control box of explosive gas atmosphere has explosion-proof types such as intrinsic safety type, flame-proof type and INCREASEDSAFETY under the coal mine, because the flame proof fail safe is higher relatively, therefore using maximum is the flame-proof type control box.The flame-proof type control box generally is made up of housing, interconnect, introducing device, closure plate etc.Often need unpacking detection or have the casing of observing device also to need chamber door and transparent member.
Summary of the invention
In order to reach the flame proof requirement, the present invention provides a kind of flame-proof type control box.When device interior was blasted, the flame proof faying face can prevent that spark and temperature from causing flammable medium blast on every side; Shell can bear inner blast pressure and not cause damaging, and can prevent that again detonation propagation is outside shell.Even break down so work as its device interior,, also can explosion hazard be completely cut off at device interior like on fire, short circuit, blast etc.
The present invention realizes with following technical scheme: a kind of flame-proof type control box, and it comprises casing, is divided into up and down two independently explosion-proof chambers in the casing; Top is the main chamber that is used to install electrical component, and the bottom is a wire connection cavity; Main chamber case lid is arranged above the main chamber, in the case lid of main chamber, be welded with connecting plate; Be fixed with pressing plate on the connecting plate; And the centre is lined with backing plate; Suspension hook is equipped with on case lid positive both sides in main chamber, and button, indicator light are equipped with in inside; The wire connection cavity cover plate is arranged above the wire connection cavity, and a suspension hook is equipped with in wire connection cavity cover plate outside, and the wire connection cavity downside is equipped with introducing device and ground connection angle steel; The folding through the side of casing and main chamber case lid, wire connection cavity cover plate is connected and realizes quick opening structure up and down; The faying face of casing and main chamber case lid, wire connection cavity cover plate is explosion-proof faying face, and the case lid outside is equipped with the switch contact lever that is used for control switch in main chamber.
Advantage of the present invention is: low cost of manufacture, compact conformation, safety anti-explosive, move characteristics flexible and easy and simple to handle, thereby satisfied user's work requirements more broadly.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further.
Fig. 1 is a front view of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
Among the figure: 1, casing; 2, main chamber case lid; 3, suspension hook; 4, wire connection cavity cover plate; 5, folding; 6, introducing device; 7, ground connection angle steel; 8, riser; 9, pressing plate; 10, guide rail; 11, main chamber; 12, base plate; 13, binding post fixed head; 14, flame proof plate I; 15, wire connection cavity; 16, connecting plate; 17, backing plate; 18, clear glass; 19, rubber gasket; 20, switch contact lever; 21, main chamber panel; 22, flame proof plate II; 23, flame proof plate III.
Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, a kind of flame proof control box housing is the rectangle stuffing box that is welded with steel plate, is made up of casing 1 and main chamber case lid 2 and wire connection cavity cover plate 4.Casing 1 and main chamber case lid 2 and wire connection cavity cover plate 4 link together through bolt.Casing 1 is the cavity on the flanged limit that is welded into by riser 8, flame proof plate III 23 and base plate 12.Bottom in casing 1 is equipped with binding post fixed head 13 and flame proof plate I 14, and binding post fixed head 13 and flame proof plate I 14 are with being divided into up and down two independently explosion-proof chambers in the casing.Top is main chamber 11, is used to install electrical component; 11 inside, main chamber; In main chamber 11, on base plate 12, be fixed with guide rail 10, guide rail 10 passes through screw on base plate 12.The bottom is a wire connection cavity 15, and wire connection cavity 15 downsides are equipped with introducing device 6 and ground connection angle steel 7; Ground connection angle steel 7 links to each other with ground wire through bolt.Main chamber case lid 2 is tightly connected through bolt and casing 1; Main chamber case lid 2 is made up of with middle outwards outstanding main chamber panel 21 flame proof plate II 22; Case lid 2 outsides, main chamber are welded with suspension hook 3, and inside is welded with connecting plate 16, and is fluted on connecting plate 16, and rubber gasket 19 and clear glass 18 are housed in the groove; Through the operating state that clear glass 18 is observed indicator light in the control cabinet, be convenient to staff's record and analyze the investigation fault; Backing plate 27 is housed in the middle of pressing plate 9 and the connecting plate 16 and passes through bolt together; Thereby pressing plate 9 compresses the effect that makes casing reach sealing through bolt with clear glass 18 and rubber gasket 19.Outside the main chamber case lid 2, switch contact lever 20 is installed, can comes control switch through switch contact lever 20.Wire connection cavity cover plate 4 is tightly connected through bolt and casing 1, and wire connection cavity cover plate 4 outsides are welded with suspension hook 3.Casing 1 and main chamber case lid 2 and wire connection cavity cover plate 4 are realized quick opening structure up and down through the folding 5 of side; Casing 1 is explosion-proof faying face with the faying face of main chamber case lid 2 and wire connection cavity cover plate 4, and explosion suppresion surface need pass through accurate processing and acid washing phosphorization and handle and reach seal request.
