Abstract
A kind of mining inclined tunnel prevent-moving car fender guard, comprises bend bracing frame, arrester, steel rope, releasing winch and PLC control cabinet, above arrester, be provided with two horizontal supports, and bend bracing frame is fixed on above two horizontal supports.Go out to be provided with two horizontal supports, in order to support releasing winch at the 5-10m in bend bracing frame dead ahead.Wall below releasing winch is provided with PLC control cabinet, and PLC control cabinet and releasing winch electrically connect, in order to control releasing winch.Steel rope one end is connected with arrester, and the other end is connected with releasing winch, and midfoot support is on bend bracing frame.The beneficial effects of the utility model are, rational in infrastructure, long service life, can use and can use in mixing tunnel again, and in-site installation does not conveniently limit by head-room in common tunnel.
Description
Technical field:
The utility model relates to a kind of mining inclined tunnel prevent-moving car fender guard, belongs to mining equipment technical field.
Background technology:
Along with the fast development of China's economy, Safety production questions is more and more subject to people's attention, and Safety of Coal Mine Production is then focus wherein always.According to statistics, coal mine accident accounts for more than 50% of Electromechanical Accidents in mining conveying lifting process, and has the trend of rising, brings huge harm to coal mine production safety, miner's life security.Therefore, how to accomplish derail avoidance work better, reduce the generation of such accident, just seem very important.Mining inclined tunnel prevent-moving car fender guard is a kind of normally closed catcher, when mine car normal through time, arrester rises automatically, and after mine car passes through, arrester falls automatically, is in normally off at ordinary times.When mine car hypervelocity (sport car, the car that slips), arrester carries out failure-free obstruction to mine car, and disconnect winch shear loop by signal feedback, winch is out of service, avoids the generation of extra heavy serious accident simultaneously.Such as, in slope tube-train hoisting, because of hitch mounting loosely or wire cable rupture etc. cause single mine car or bunching to lose traction, be in state of weightlessness, the phenomenon naturally doing accelerated movement along slope track is downwards called " sport car ".In mining production, mining conveying casualty accident is more, and be wherein one of its multiple incidents with haulage vehicle accident again, derailing accident can cause serious personal injury or huge economic loss.At present, the buffer stop in the mixing tunnel having pedestrian's cable car and mine car has two lifting of winch, two air cylinder lifting, and ground plays several mode of formula.The shortcoming of multiple twin car hoisting way: must use two releasing winch, two P cocks control arrester, and installation period is long, and fault rate is high, safeguard inconvenience, limit by head-room.Two air cylinder lifting mode shortcoming: affect greatly by down-hole source of the gas, arrester operating state is unstable, safeguards inconvenience, limits by head-room.Ground plays formula shortcoming: installation period is long, and quantities is large, et out of order during use, recovers more difficult, needs for a long time, and does not meet normally off requirement.
Summary of the invention:
The purpose of this utility model is the deficiency in order to overcome existing mining inclined tunnel prevent-moving car fender guard, and the present invention can use and can use having pedestrian's cable car and have in the mixing tunnel of mine car in common tunnel, and not by the restriction of tunnel setting height(from bottom).
For achieving the above object, the technical solution adopted in the utility model is:
A kind of mining inclined tunnel prevent-moving car fender guard, comprises bend bracing frame, arrester, steel rope, releasing winch and PLC control cabinet, above arrester, be provided with two horizontal supports, and bend bracing frame is fixed on above two horizontal supports.Go out to be provided with two horizontal supports, in order to support releasing winch at the 5-10m in bend bracing frame dead ahead.Wall below releasing winch is provided with PLC control cabinet, and PLC control cabinet and releasing winch electrically connect, in order to control releasing winch.Steel rope one end is connected with arrester, and the other end is connected with releasing winch, and midfoot support is on bend bracing frame.
Further, described bend bracing frame is diagonal ligament frame, and the one end above arrester is designed to reclinate arc, is provided with supporting leg below bend bracing frame, and is fixed in two horizontal supports of front portion, tunnel by supporting leg.Be provided with roller in the rear and front end of bend bracing frame, in order to supporting steel-cable, reduce the friction force between bend bracing frame and steel rope.
Further, described arrester is steel rope arrester.
Principle of work: when mine car needs through arrester, PLC control cabinet sends instruction to releasing winch, releasing winch is started working, arrester rises, arrester is guided by the roller of bend bracing frame and mentions position, arrester is pulled on bend bracing frame along with steel rope, and mine car just can safety.After mine car passes through, releasing winch puts rope, and arrester slowly falls under the effect of self gravitation, stops action after putting in place, recovers normally off.When pedestrian's row cable car, arrester continues to fall from normally off, stops after putting in place, and in orbit, pedestrian's cable car runs in arrester tiling.After pedestrian's cable car is out of service, recover normally off.
The beneficial effects of the utility model are, simple and reasonable for structure, can reduce energy consumption, long service life, can use in common tunnel and can use taking advantage of in people's cable car and mine car mixing tunnel again, and in-site installation is convenient does not limit by head-room, easy reparation after accident occurs.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of bend bracing frame.
1 horizontal support, 2 bend bracing frames, 21 rollers, 22 supporting legs, 3 arresters, 4 steel ropes, 5 releasing winch, 6 PLC control cabinet in figure.
Detailed description of the invention:
As shown in Figure 1; a kind of mining inclined tunnel prevent-moving car fender guard; comprise bend bracing frame (2), arrester (3), steel rope (4), releasing winch (5) and PLC control cabinet (6); be provided with two horizontal supports (1) in arrester (3) top, bend bracing frame (2) is fixed on above two horizontal supports (1).Go out to be provided with two horizontal supports (1) at the 5-10m in bend bracing frame (2) dead ahead, in order to support releasing winch (5).Wall below releasing winch (5) is provided with PLC control cabinet (6), PLC control cabinet (6) and releasing winch (5) electrically connect, in order to control releasing winch.Steel rope (4) one end is connected with arrester (3), and the other end is connected with releasing winch (5), and middle part is supported on bend bracing frame (2) by supporting leg (22).Change the structure that original mining inclined tunnel prevent-moving car fender guard need be carried out controlling by two releasing winch (5) arrester (3), make this mining inclined tunnel prevent-moving car fender guard structure simple, reduce energy consumption.
As shown in Figure 2, described bend bracing frame (2) is diagonal ligament frame, and be fixed in the horizontal support (1) of arrester (3) top, its one end is designed to reclinate arc, and is fixed on two horizontal supports (1) of front portion, tunnel by supporting leg (22).Be provided with roller (21) in the rear and front end of bend bracing frame (2), in order to supporting steel-cable (4), reduce the friction force between bend bracing frame (2) and steel rope (4), the service life of extension fixture.
