Abstract
The utility model discloses a replaceable flame-proof wiring chamber. The replaceable flame-proof wiring chamber comprises a wiring chamber housing, a wiring chamber top gate weldment, an introducing device and terminals. The upper surface and front side surface of the wiring chamber housing are respectively connected with a flange by welding for a flame-proof joint surface, each flange is uniformly provided with a ring of screwed holes, the screwed holes are blind holes, the front side surface of the wiring chamber housing connected with a main shell is provided with installing holes for arranging the terminals, the back side surface of the wiring chamber housing is connected with the installation mechanism of the introducing device by welding, and the upper surface of the wiring chamber housing is connected with the wiring chamber top gate weldment with the flame-proof joint surface through a screw. According to the replaceable flame-proof wiring chamber, when the cable diameter under a mine changes suddenly, the main wiring chamber can be directly replaced without replacing the whole machine, which is convenient for replacement. The product utilization rate is raised, processing and manufacture costs are saved, replacement is simple, and a manufacture period is short.
Description
Technical field
The utility model relates to mining electromechanical equipment field, more particularly, relates to a kind of removable explosion insulation connecting line cavity.
Background technology
Explosion insulation connecting line cavity is applicable to the place of flame proof requirement, methane blended gas and coal dust is particularly arranged and have under the coal mine of explosion hazard.It reaches explosion-proof requirement by high-intensity housing and effective explosion-insulation surface.In existing design, the main electrical scheme chamber is all to be welded on main casing, is fixed into the form of a certain external line, and in the situation that can't change connection type not changing main casing under coal mine.If the words that must change can only be changed main casing, waste time and energy, affect production efficiency.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provide a kind of simple in structure, change fireballing removable explosion insulation connecting line cavity.
The removable explosion insulation connecting line cavity of the utility model, by following technical proposals, be achieved, comprise wire connection cavity housing, wire connection cavity roof door weldment, introducing device and binding post, described wire connection cavity housing upper surface and leading flank are welded with respectively the explosion-insulation surface adpting flange, one circle screwed hole evenly is set on described adpting flange, and described screwed hole is blind hole; The described wire connection cavity housing leading flank be connected with main casing is with the installing hole that binding post is installed, and wire connection cavity housing trailing flank is welded with the installing mechanism of introducing device; Described wire connection cavity housing upper surface is connected by screw the wire connection cavity roof door weldment with explosion-insulation surface.
Described installing hole is the flame proof installing hole.
Described introducing device is press disc type introducing device or fast-connecting type cable connector.
Described installing mechanism is communicating joint or connects soon the cable connector mounting flange.
On the roof door weldment of described main electrical scheme chamber, alarm plate is installed.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is realized in colliery the connection requirement to different model and wire diameter cable.Can realize carrying out the pre-configured of product according to the specification of colliery cable wire diameter, as the burst that runs into cable wire diameter under ore deposit changes and can change complete machine and directly change the main electrical scheme chamber and get final product, be convenient for changing.
The utility model has been realized that the burst as run into cable wire diameter under ore deposit changes and can have been changed complete machine and directly change the main electrical scheme chamber, has been convenient for changing.Improved the utilance of product, saved the cost of processing and fabricating simultaneously, change easy, the advantage such as fabrication cycle is short.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structure cutaway view.
In figure:
1. binding post 2, roof door attachment screw 3, wire connection cavity roof door weldment 4, alarm plate
5, introducing device 6, wire connection cavity housing 7, screw 8, normal type single coil spring lock washer
9, plain washer 10, main casing adpting flange 11, explosion insulation connecting line cavity adpting flange.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As illustrated in fig. 1 and 2, comprise wire connection cavity housing 6, wire connection cavity roof door weldment 3, introducing device 5 and binding post 1, introducing device is press disc type introducing device or fast-connecting type cable connector; Described wire connection cavity housing upper surface and leading flank are welded with respectively adpting flange for explosion-insulation surface (leading flank is explosion insulation connecting line cavity adpting flange 11), and a circle screwed hole evenly is set on described adpting flange, and described screwed hole is blind hole; The described wire connection cavity housing leading flank be connected with main casing is with the installing hole that binding post is installed, and installing hole is the flame proof installing hole; Wire connection cavity housing trailing flank is welded with the installing mechanism of introducing device, and installing mechanism is communicating joint or connects soon the cable connector mounting flange; Described wire connection cavity housing upper surface, by the wire connection cavity roof door weldment of roof door attachment screw 2 connecting band explosion-insulation surfaces, is installed alarm plate 4 on the roof door weldment of main electrical scheme chamber.Described removable explosion insulation connecting line cavity is by the main casing flange 10 of screw 7 connecting band explosion-insulation surfaces.And explosion-insulation surface meets colliery equipment national standard.Only need change corresponding wire connection cavity as the mode of connection of need replacing cable and get final product, conveniently connect soon.
Details are as follows in use:
After (comprising all parts that remove wire connection cavity roof door weldment 3 in Fig. 1) after wire connection cavity is assembled into to assembly, by screw 7, normal type single coil spring lock washer 8, the plain washer 9 be connected with main casing, wire connection cavity is connected together with main casing adpting flange 10, meet the flame proof requirement simultaneously, finally wire connection cavity roof door weldment 3 is connected together with roof door attachment screw 2 with wire connection cavity.When the needs external cabling, unload wire connection cavity roof door weldment 3, cable is introduced after wire connection cavity with after corresponding binding post is connected, cover wire connection cavity roof door weldment 3 and tighten.As the burst that runs into the model of ore deposit side's cable or wire diameter or type of attachment changes, need not change complete machine, only need the main electrical scheme chamber of changing respective model can meet instructions for use.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
