Abstract
The utility model relates to a kind of timing failure device of quick investigation coalcutter, is installed on coalcutter, a resistance in parallel and a light emitting diode on 12V intrinsic safety electric source in described coalcutter; Described coal cutter frequency converter declutches a resistance in parallel and a light emitting diode on output circuit; A resistance in parallel and a light emitting diode on pressure switch in described coalcutter; Described coal cutter frequency converter declutches and confirms a resistance in parallel and a light emitting diode on circuit.After adopting foregoing circuit mode, by connecting warning circuit in the position of often breaking down, can judge in time when breaking down timing failure really allocation keep in repair, save servicing time, enhance productivity, structure is simple, easy to connect.
Description
Technical field
The utility model relates to industrial and mineral Instrument technology field, especially relates to a kind of timing failure device of quick investigation coalcutter.
Background technology
At present, gather in technical field in colliery, coalcutter generally uses, in order to keep the safety in production, coalcutter by sequential band-type brake declutch detection operation, in producing in reality, how loaded down with trivial details the sequential system point that declutches is, will open three to four control chambers (junction box chamber once break down, public control enclosure chamber, XBF wire connection cavity, frequency converter chamber) overhaul, dealing with and also extremely bother, within the shortest time, how to find out the trouble spot of this fault, is the key point winning the production time.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of investigation capable of rapid positioning and is out of order the timing failure device of quick investigation coalcutter a little.
The technical scheme in the invention for solving the technical problem is: a kind of timing failure device of quick investigation coalcutter, be installed on coalcutter, described coalcutter comprises 12V intrinsic safety electric source, coal cutter frequency converter declutches output circuit, pressure switch in coalcutter and coal cutter frequency converter declutch confirmation circuit, it is characterized in that, a resistance in parallel and a light emitting diode on 12V intrinsic safety electric source in described coalcutter, can detect the duty of 12V intrinsic safety electric source fast.
Concrete further, conveniently detect frequency converter and to declutch the duty of output circuit, described coal cutter frequency converter declutches a resistance in parallel and a light emitting diode on output circuit.
Concrete further, the conveniently duty of detected pressures relay, a resistance in parallel and a light emitting diode on the pressure switch in described coalcutter.
Concrete further, conveniently detection transformer declutches and confirms the duty of circuit, and described coal cutter frequency converter declutches and confirms a resistance in parallel and a light emitting diode on circuit.
Beneficial aspects of the present utility model is: after adopting foregoing circuit mode, by connecting warning circuit in the position of often breaking down, can judge in time when breaking down timing failure really allocation keep in repair, save servicing time, enhance productivity, structure is simple, easy to connect.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is explained in detail.
A kind of timing failure device of quick investigation coalcutter as shown in Figure 1, be installed on coalcutter, a kind of timing failure device of quick investigation coalcutter, be installed on coalcutter, described coalcutter comprises 12V intrinsic safety electric source, coal cutter frequency converter declutches output circuit, pressure switch in coalcutter and coal cutter frequency converter declutch confirmation circuit, a resistance in parallel and a light emitting diode on 12V intrinsic safety electric source in described coalcutter; Described coal cutter frequency converter declutches a resistance in parallel and a light emitting diode on output circuit; A resistance in parallel and a light emitting diode on pressure switch in described coalcutter; Described coal cutter frequency converter declutches and confirms a resistance in parallel and a light emitting diode on circuit.
Warned by the place that light emitting diode is easily being damaged, can keep in repair efficiently in time.
By connecting warning circuit in the position of often breaking down, can judge in time when breaking down timing failure really allocation keep in repair, save servicing time, enhance productivity, structure is simple, easy to connect.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
