Description
Technical field
The present invention relates to a kind of control system of coal mine fully-mechanized mining working transporter, relate in particular to the automatic control system of altering downslide on a kind of transporter.
Background technology
Seams in coal production is self-assembling formation, and the gradient can be divided into nearly level, gentle dip, inclination, high-dipping.Most of fully-mechanized mining working has certain gradient to exist, transporter, support are due to the effect of gravity, can produce and glide, if control badly, can cause coal stream to go out the accident such as conveyor, head pedestrian insufficient space, simultaneously, in the time adjusting downslide, if control badly, transporter can occur to alter, and causes coal stream to reach the accident such as conveyor machine, tail pedestrian insufficient space.Between the bank changing in the work plane gradient, the pseudo-tilt length of work plane can change, and transporter length can be relatively long or too short, produces on different and alters or glide, and adjustment work is very loaded down with trivial details.
On traditional, altering downslide solution is the roughly gradient according to work plane, by experience, lower crossheading is exploited in advance, and general 200 meters of left and right work planes, the gradient 1 is spent, leading 1 meter.Namely go out to cut after eye, head is adopted two cutter coals, and tail is adopted a cutter coal, so progressively adjusts.Whether frame head and tail there is altering downslide, by visually observing.This method of adjustment error is large, precision is not high, simultaneously owing to adopting micro-judgment and artificial adjustment, very large to personnel's dependence, is unfavorable for enforcement unmanned under coal mine.
Summary of the invention
For addressing the above problem, the present invention proposes to alter downslide automatic control system on a kind of transporter, comprises transporter, working surface hydraulic support and central computer; Described transporter comprises head and tail, and head laser range finder is installed on described head, and tail rangefinder is installed on described tail, and described head rangefinder is connected described central computer with tail rangefinder; Described central computer connects described working surface hydraulic support, for according to the pushing and sliding stroke of working surface hydraulic support described in the survey data control of described head rangefinder and tail rangefinder.
Preferred described working surface hydraulic support comprises head rack and tail support.
Preferably also comprise coal-winning machine, be provided with coal-winning machine navigation system on described coal-winning machine, described coal-winning machine navigation system connects described central computer.
The invention has the advantages that:
1, monitor in real time transporter on alter downslide, generation problem is adjusted at any time, reaction is fast, efficiency is high;
2, adjust and alter downslide by computer, adjust precision high;
3, whole method of adjustment, completely by computer control, is conducive to the unmanned implementation of work plane;
4, by connecting coal-winning machine navigation system, will on alter to glide and join together with the work plane gradient, can on look-ahead, alter the possibility of generation that glides, and carry out anticipation adjustment targetedly for above-mentioned possibility.
Accompanying drawing explanation
Accompanying drawing 1 is for altering the structural representation of downslide automatic control system on transporter of the present invention.
Reference numeral is as follows:
1-transporter; 2-coal-winning machine; Lane on 3; 4-Xia lane; 5-work plane; 6.1,6.2,6.3-working surface hydraulic support; 7-elevating conveyor; 11-head; 12-tail.
The specific embodiment
Referring to accompanying drawing 1, it has described an embodiment of inclined cut conveyor system.Conveyor system comprises transporter, it is arranged along the work plane tilting, two ends are respectively head and tail, coal-winning machine moves along transporter, and the coal of exploiting falls into transporter, by the head of transporter, enter the conveyor in elevating conveyor, upper lane, for the reprinting of coal, in the time that coal-face advances, make coal-winning machine and transporter follow-up by the pushing and sliding of the working surface hydraulic support associated with transporter.In actual production, due to reasons such as gravity, transporter entirety can move to heading gradually, glides, and coal stream exceeds elevating conveyor, causes again pedestrian's insufficient space after mobile elevating conveyor, need to adjust.Meanwhile, in the process gliding in adjustment, also may be due to excessive adjustment, transporter entirety is moved to tail head direction, occur to alter
In method of the present invention, need to accurately obtain the physical location of transporter, therefore first at head and the tail of transporter, laser range finder is installed respectively, be respectively used to measure head, the tail distance with respect to adjacent tunnel; In this embodiment, the laser range finder of head is measured the distance of Qi Yushang lane wall, and the laser range finder of tail is measured the distance of Qi Yuxia lane wall, and in actual applications, laser range finder should be measured the distance of itself and immediate wall.The distance of measurement is transferred to respectively central computer by laser range finder, central computer can use the existing computer system of work plane, as console for centralized control etc., central computer is compared this distance with preset value, on judging whether to occur, alter or glide, relatively can follow following steps: as head be relatively less than with the distance in tunnel as described in preset value and tail relative with distance tunnel be greater than as described in preset value, be judged as and glide; As head be relatively greater than with the distance in tunnel as described in preset value and tail relative with distance tunnel be less than as described in preset value, be judged as in generation and alter; As head be relatively greater than with the distance in tunnel as described in preset value, and tail distance relative and tunnel is greater than described preset value, is judged as normal operating conditions; As head be relatively less than with the distance in tunnel as described in preset value, or tail relatively and the distance in tunnel be less than described preset value, in the generation of judgement system, alter downslide.The concrete quantity rules of above-mentioned preset value do not stipulate, regulation departs from head with elevating conveyor centre distance should be more than or equal to 150mm under normal circumstances, consider and will guarantee to export up and down under unimpeded prerequisite, suitably increasing.
The in the situation that of altering or glide on judgement occurs, adjustment programme is undertaken by the working surface hydraulic support pushing and sliding stroke of head, tail: while above altering, head rack (being the working surface hydraulic support 6.1 in accompanying drawing) scraper-trough conveyer pushes away half cutter, tail support (being the working surface hydraulic support 6.3 in accompanying drawing) scraper-trough conveyer pushes away whole cutter; When downslide, head rack (being the working surface hydraulic support 6.1 in accompanying drawing) scraper-trough conveyer pushes away whole cutter, tail support (being the working surface hydraulic support 6.3 in accompanying drawing) scraper-trough conveyer pushes away half cutter.Force by the way transporter upwards to be altered or the rightabout that glides moves, to overcome the problem of generation.
In optional technical scheme; central computer can also be connected with coal-winning machine navigation system; coal-winning machine navigation system is for the real-time change situation of the collecting work face gradient; can predict and alter the possibility that glides and occur by collecting work face slope change situation; as the words that the gradient strengthens just can think that front can glide conventionally; now adjust transporter attitude by working surface hydraulic support in advance by aforesaid method, accomplish to prevent trouble before it happens.
The above; it is only the preferably specific embodiment of patent of the present invention; but the protection domain of patent of the present invention is not limited to this; anyly be familiar with in technical scope that those skilled in the art disclose in patent of the present invention; the variation that can expect easily or replacement, within all should being encompassed in the protection domain of patent of the present invention.
