Abstract
The utility model discloses a flame-proof type mining winch control cabinet, which comprises flame-proof box body assembly and a control circuit mounted in the cavity of a flame-proof box; the control circuit comprises an AC contactor, a self-locking button and a combination button; the input terminal of the AC contactor is connected with an AC power supply of 127 V; the output terminal of the AC contactor is connected with the self-locking button; and the combination button is connected with a winch magnetic starter. By the adoption of the technical scheme, the forward operation, the backward operation and the stoppage of a winch are controlled by an acousto-optic signal, a ring, an alarming red light and a voice warning device, so that ubiquitous defects and hidden dangers in the conventional wiring mode of coal mine underground alarming red light are solved.
Description
Technical field
The utility model relates to a kind of flame-proof mine winch control box, belongs to underground mine use electrical control field.
Background technology
" safety regulations in coal mine " the 46 regulation: during inclined shaft (lane) construction period double as street crossing, must manhole is set and establish red light every 40 meters.A side that is provided with manhole must have unimpeded footway.Personnel must walk the footway up and down.Red light is bright during driving, and the pedestrian enters manhole immediately; After red light extinguishes, can walk.
Endless rope winch, car hauler, return and lean on winch and use very extensively in colliery inside slope (lane) transportation, the correct place in operation of reliably unimpeded, the caution red light of its signal system is the prerequisite basic condition of exploiting field winch safe operation.At present, following two kinds of modes of connection are generally adopted for the 127V caution red light system of exploiting field, down-hole winch in most collieries.
A kind ofly be: a pair of auxiliary normal opened contact in the magnetic starter of 127V caution red light power utilization winch, draw the break-make of distance control caution red light by the 8# in the magnetic starter wire connection cavity of QBZ lamp series, 13# terminal; Its defective is: (1) caution red light and winch move synchronously but can not give warning in advance; In use vehicle slides down, during the processing accident, but can not light when the caution red light should be warned.(2) no matter whether winch moves, and the phase power supply heart yearn in the caution red light circuit has voltage to exist for a long time, causes an illusion for easily dynamo-electric service personnel, causes error shock.(3) as if 127V power supply dead electricity in service, hoistman still can break rules and regulations to drive.(4) this mode is violated " safety regulations in coal mine " 448: the regulation of " rated voltage of distance control circuit is no more than 36V ".
Another kind is: no matter be foot-operated or manual mode, utilize clamped " dedicated button " to control the break-make of red light 127V power supply.Before the winch operation, " dedicated button " operated, so that 127V red light power path reaches red light and lights the purpose of warning.Its defective is: it is bigger that (1) is influenced by human element.Driver's inoperation " dedicated button ", then under the situation that the caution red light is not lighted, winch also can move; (2) frequent break-make and contact contact comparatively slowly all very easily cause the interior burning of contact of explosion-proof button.
Summary of the invention
Technical problem to be solved in the utility model is that winch control is unreliable, human element big, the problem of system's poor durability.
In order to solve the problems of the technologies described above, the utility model provides a kind of flame-proof mine winch control box, comprise assembly flameproof cabinet and the control circuit that is installed in the Flameproof box cavity, described control circuit comprises AC contactor, locking press button and combination button, wherein the AC contactor input end connects the 127V source of AC, mouth connects locking press button, and described combination button connects the winch magnetic starter.
Further, described AC contactor input end also is connected with caution power supply red light, caution red light and phonetic alarm device.
Further, be connected a contactless switch with caution between the red light at described AC contactor input end.
Further, described caution red light is 3 groups, and these 3 groups caution red light mean allocation are on the 127V three phase line.
As a kind of preferred version, be stamped warning lamp start and stop, forward, oppositely and stop control button on the described assembly flameproof cabinet.
The beneficial effects of the utility model are:
1, technical solutions of the utility model have solved caution ubiquitous deficiency of the red light mode of connection and hidden danger under the present coal mine with forward and reverse operation of winch and stop to be controlled by sound and light signal, some bell, caution red light and phonetic alarm device.
2, this control box of technical solutions of the utility model can balanced 127V threephase load electric current, during installation with the red light mean allocation to the 127V three phase line, solved mining illumination sign and combined the secondary side three-phase current unbalance problem of protecting voltage transformer.
3, between the utility model red light and the power supply contactless switch is installed,, only needs to disconnect contactless switch in the control box in when maintenance, just can operation, and can not have influence on the operation of other equipment.
Description of drawings
Below in conjunction with the drawings and specific embodiments technical solutions of the utility model are described in further detail.
Fig. 1 is the circuit theory scheme drawing of the utility model mine explosion-suppression winch control box.
The specific embodiment
The utility model flame-proof mine winch control box is by assembly Flameproof box and the control circuit that is installed in the Flameproof box cavity, as shown in Figure 1, described control circuit comprises AC contactor, locking press button and combination button, wherein the AC contactor input end connects the 127V source of AC, mouth connects locking press button, and described combination button connects the winch magnetic starter.Described AC contactor input end also is connected with caution power supply red light, caution red light and phonetic alarm device.Be connected a contactless switch with caution between the red light at described AC contactor input end.Described caution red light is 3 groups, and these 3 groups caution red light mean allocation are on the 127V three phase line.Be stamped warning lamp start and stop, forward, oppositely and stop control button on the described assembly flameproof cabinet.Described warning lamp start and stop, forward, oppositely and stop control button being used for respectively start and stop caution red light and phonetic alarm device, the forward and reverse operation of winch, stop the effect of winch running indicator.1,2,3,9 is control conection styletable, is used for distant place control winch magnetic starter and uses.
The utility model protection domain is not limited to above-mentioned embodiment, and every technology distortion of being done according to the utility model know-why all falls within the protection domain of the present utility model.
