Abstract
The invention relates to an automatic blocking device for a locomotive at an intersection of an underground transportation main haulage roadway of a coal mine. The automatic blocking device comprises an electric locomotive overhead line. The electric locomotive overhead line comprises a straight roadway overhead line on a straight roadway and an oblique roadway overhead line on an oblique roadway. The straight roadway overhead line and the oblique roadway overhead line are connected with a power supply. A first inductor is arranged at the front end of the intersection between the straight roadway and the oblique roadway and is located in the straight roadway. A second inductor is arranged at the front end of the intersection between the straight roadway and the oblique roadway and is located in the oblique roadway. A third inductor is arranged at the rear end of the intersection between the straight roadway and the oblique roadway and is located in the straight roadway. The first inductor, the second inductor and the third inductor are connected with a control end. By the adoption of the structure, the transportation efficiency of the locomotive on the main haulage roadway is improved; the structure is simple, the technique is advanced, the functions are complete, movement is flexible, the performance is reliable, and maintenance is convenient; in addition, the audible and visual alarm function and the display function are achieved, transportation accidents of the locomotive on at the intersection of the main haulage roadway are eliminated, the safety of people is ensured when people go through the the intersection of the main haulage roadway, and losses are reduced.
Description
Technical field
The present invention relates to mining conveying tool technique industry, especially relate to a kind of underground coal mine main haulage roadway prong locomotive automatic block equipment.
Background technology
In mining activities industry, transportation safety under mine becomes more and more important, mine main fortune main road haulage safety management difficulty, because locomotive turnover number of times is comparatively frequent, if motive power control monitoring is unfavorable or electric locomotive driver contacts vehicles passing in and out privately, fail to act normal turnover car report procedure, electric locomotive will cause because sight line is unclear locomotive to meet and discuss at Special zone such as great Xiang crossings, knocks into the back or wipe the safety misadventures such as side, thus cause work stoppage, cause economic damage, increase cost.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of underground coal mine main haulage roadway prong locomotive automatic block equipment that locomotive can be avoided to meet and discuss, knock into the back or wipe the safety misadventure generations such as side.
The present invention solves the technical scheme that its technical matters takes: a kind of underground coal mine main haulage roadway prong locomotive automatic block equipment, comprise electric vehicle overheading line, described electric vehicle overheading line comprises the inclined gallery air wire on straight Xiang Shangzhi lane air wire and inclined gallery, described straight lane air wire and inclined gallery air wire are connected with power supply, the first inductor is provided with in the straight lane, front end of the crossing of described straight lane and inclined gallery, the second inductor is provided with in the inclined gallery, front end of the crossing of described straight lane and inclined gallery, the 3rd inductor is provided with in the straight lane, rear end of the crossing of described straight lane and inclined gallery, the first described inductor, second inductor and the 3rd inductor are connected with control end, the first inductor described in straight lane senses electric locomotive arrival signal, by signal transmission to control end, control end controls the electric locomotive stop motion in inclined gallery, treat electric locomotive by after the 3rd inductor by signal transmission to control end, control end controls the electric locomotive setting in motion in inclined gallery.
Concrete further, described straight lane air wire and inclined gallery air wire are equipped with auto-power-off device and are connected with control end.
Concrete further, described straight lane and the crossing of inclined gallery are provided with warning device.
Concrete further, described locking device is controlled by PLC system.
The invention has the beneficial effects as follows: after have employed said structure, stop the generation of friendship fork, Liao great lane Special zone shipping accident, improve large lane locomotive transportation work efficiency, and its structure is simple, advanced technology, multiple functional, be active in one's movements, dependable performance, easy to maintenance, separately add sound and light alarm, Presentation Function, to pass through safety the personnel that stop to also ensure outside the locomotive transportation accident of friendship fork, large lane, reduce loss.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, straight lane air wire; 2, inclined gallery air wire; 3,4, auto-power-off device; 5, the first inductor; 6, the second inductor; 7, control end; 8, the 3rd inductor.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is explained in detail.
A kind of underground coal mine main haulage roadway prong locomotive automatic block equipment as shown in Figure 1, comprise electric vehicle overheading line, described electric vehicle overheading line comprises the inclined gallery air wire 2 on straight Xiang Shangzhi lane air wire 1 and inclined gallery, described straight lane air wire 1 and inclined gallery air wire 2 are connected with power supply, the first inductor 5 is provided with in the straight lane, front end of the crossing of described straight lane and inclined gallery, the second inductor 6 is provided with in the inclined gallery, front end of the crossing of described straight lane and inclined gallery, the 3rd inductor 8 is provided with in the straight lane, rear end of the crossing of described straight lane and inclined gallery, the first described inductor 5, second inductor 6 and the 3rd inductor 8 are connected with control end 7, the first inductor 5 described in straight lane senses electric locomotive arrival signal, by signal transmission to control end 7, control end 7 controls the electric locomotive stop motion in inclined gallery, treat electric locomotive by after the 3rd inductor 8 by signal transmission to control end 7, control end 7 controls the electric locomotive setting in motion in inclined gallery, described straight lane air wire 1 and inclined gallery air wire 2 are equipped with auto-power-off device 3,4 be connected with control end 7, described straight lane and the crossing of inclined gallery are provided with warning device, described locking device is controlled by PLC system.
Must contact aerial leeched line inductor when locomotive passes through crossing, now right of way signal is delivered to control end, control end controls auto-power-off device, while sending " locomotive passes through; slow down " language alarm, auto-power-off device starts action, the air wire realizing another prong is cut off the electricity supply, locomotive loses power drives, stop voluntarily, turnover car completely by after handing over fork remote, by inductor by signal transmission to control end, the locomotive that control end controls another prong can be energized current.And when locomotive passes through, in conjunction with locomotive monitoring system technology, switch voluntarily at the turnover machine of crossing, guarantee that locomotive passes through unblocked.Can say, technique provides safety control really at hardware facility, avoids to cause two cars to meet, meet and discuss and wipe the generation of side accident because of electric locomotive driver not according to chapter operation, improves the safe and efficient property of main road haulage.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
