Description
Technical field
The utility model relates to a kind of colliery technical field, relates in particular to a kind of anti-running device for incline that is applicable to mine hoisting transport.
Background technology
Colliery gradient tunnel Lifting Convey operation is the important step in Safety of Coal Mine Production, and in many middle-size and small-size mines, gradient tunnel rail transport is still mainly transported as it, also has a lot of rail transport inclined gallery at large-scale mine.The transportation mode often adopting in inclined shaft transport is above inclined shaft, to settle winch traction mine car transported material.In actual tilt roadway rail transport production process, because the reasons such as bunching coupling of vehicles is bad, traction steel wire fracture of rope cause mine car rapidly to fall along track, therefore derailing accident has caused great personal casualty and economic loss to coal production.Prevention of sliding-down in inclined well problem is the thorny problem of being badly in need of solution in coal production always." safety of coal mines regulation " requirement must be provided with catcher in the gradient tunnel rail transport of colliery for this reason.
The main catcher adopting has arrester, stop buffer, automatic car catcher, crotch stop buffer etc. at present, by interception equipment is set in orbit, after inclined shaft generation derailing accident, can stop mine car to move downward.But these blocking apparatus can only disposablely use mostly, both waste material, destroy again the continuity of coal production.Process when accidental cost and effort.Another kind ofly detected and stopped mine car by arrester or the net of keeping off a car again it is braked by infrared or sensor, as the patent No. 201220280163.6, title " buffer stop " is exactly wherein a kind of.This type of buffer stop is by various detecting devices, as radar Sensor monitoring device, photoelectric sensing apparatus and speed sensor etc., the installation and maintenance cost of equipment is higher, in the inclined shaft of growing at some, also need to install three above buffer stops, this has more increased cost of installation and maintenance cost.
Utility model content
The utility model is exactly in order to overcome the above problems, and the anti-running device for incline of a kind of energy repeated usage and energy gradual braking is provided.
In order to achieve the above object, the utility model provides a kind of anti-running device for incline, comprise the drg being connected with mine car, the bottom of described drg is connected with two groups of road wheels that move along slope track by pillar stiffener, between the road wheel of described the same side, connected by the connecting portion of groove shape, directly over the groove of described connecting portion, be provided with brake wheel, described brake wheel is connected with the piston rod of the hydraulic actuating cylinder of being located at brake inside, and the oil inlet end of described hydraulic actuating cylinder is connected with the oil outlet end of solenoid directional control valve; Between described connecting portion and brake wheel, be provided with brake wire along slope track direction; The bottom of described slope track and top are respectively equipped with lower contact switch and upper contact switch, and described lower contact switch, upper contact switch are connected in series by electric wire with described solenoid directional control valve; Described mine car is connected with haulage cable by travel switch, and described travel switch is connected in series with solenoid directional control valve.
Further, in braking procedure, for fear of impacting great efforts, one end of described brake wire is provided with cushion cylinder.
Further, described lower contact switch, travel switch are open contact switch, and upper contact switch is normally closed contact switch.
Further, be positioned on the pillar stiffener of drg the same side and offer the rope hole for wearing brake wire, described rope hole is positioned at the top of connecting portion.
The utility model is by connecting a drg at the front end of mine car, and there is the sport car phenomenons such as traction steel wire fracture of rope in the time that inclined shaft hoisting transport time, drg can be braked immediately, prevents mine car downslide and the personnel that cause injure and property damage.When mine car is during in inclined shaft bottom, lower contact switch disconnects, travel switch does not have stressed and closed, solenoid directional control valve is energising no, the piston rod of its hydraulic actuating cylinder is contraction state, makes the brake wheel being attached thereto also in suspension status, between brake wheel and connecting portion, is released state, because the two ends of brake wire are top and the bottoms that is fixed on slope track, so drg can move on slope track by road wheel along brake wire.In the time boosting lower contact switch on mine car, lower contact switch is connected, and haulage cable is normal, and stressed its contact of travel switch disconnects, and solenoid directional control valve is energising no.In the time boosting upper contact switch on mine car, upper contact switch normally closed contact disconnects, and solenoid directional control valve is energising no.And when mine car traction steel wire fracture of rope in the time that slope track rises, due to mine car be positioned under, the centre of upper contact switch, they are on-state, when traction steel wire fracture of rope, travel switch does not have stressed and closed, connect circuit and make solenoid directional control valve energising, exporting the piston rod that high pressure oil orders about hydraulic actuating cylinder stretches out, drawing connected brake wheel moves downward and carries out wedging with the groove of connecting portion, brake wire is pressed in the middle of them tightly, mine car and brake wire are embraced integral, give one, mine car power upwards, thereby reach the object that mine car is not glided.
So the utlity model has following beneficial effect:
(1) catcher of the present utility model is connected drg in the time that needs use with mine car, and can repeated multiple timesly use, and saves cost, and does not affect normal coal production;
(2) this device is realized when fracture is occurred mine car steel rope to and can be braked in time in conjunction with hydraulic efficiency pressure system and solenoid directional control valve, avoids the generation of sport car phenomenon, improve safety that mine produces with through agent.
(3) because the one end at brake wire is provided with cushion cylinder, thereby reach buffering effectively, avoid fierce collision occurs in the time of braking, and cause other burst accidents.
