Abstract
The utility model discloses a pneumatic vehicle blocking device. The pneumatic vehicle blocking device comprises a support arranged at the bottom, a vehicle blocking device body is arranged in the middle of the support, the middle of the vehicle blocking device is hinged to the support, an air cylinder is arranged on one side of the support, the end portion of a piston rod of the air cylinder is hinged to the bottom of the vehicle blocking device, an air inlet of the air cylinder is communicated with a compressed air inlet through a pipeline, and a control valve and a filtering device are arranged on the pipeline in a communicated mode. The pneumatic vehicle blocking device has the advantages of being safe, easy and convenient to operate, low in fault rate, small in daily maintenance amount and low in cost, improving the safety coefficient of inclined drift transport, and reducing labor intensity of staff. Because compressed air serves as power, the air cylinder is remotely controlled by the control valve, and facilities like air filters and gas-water separators are additionally arranged to filter the compressed air, the phenomenon that the piston rod of the air cylinder intermittently stretches and contracts quickly or slowly because of many impurities in the compressed air is avoided, and normal and safe operation of the vehicle blocking device and personal safety of operation personnel are guaranteed.
Description
Technical field
The utility model relates to coal mine sloping lane transportation insurance device, especially relates to a kind of Pneumatic car stopper.
Background technology
The safety in production of gradient tunnel Lifting Convey is an important step of Safety of Coal Mine Production work.In recent years, it is many that the slope accident accounts for the ratio of mine accident sum, and the major cause that causes the slope shipping accident to occur has: the derailing accident that the traction steel wire fracture of rope causes; Stop device is not made good use of the derailing accident caused; The derailing accident that bunching latch barefoot pin and lugless joining shackle fracture cause; The derailing accident that winch poor safety performance safety device lost efficacy and causes; Mistake is giveed a signal and is caused derailing accident; The not firm winch in puffer basis is drawn race.Above-mentioned reason cause mine car or mine car group in the situation that out of control along inclined shaft dart and under, this class accident harm is very big, except overturning excavation support, break the facility such as cable, airduct, water pipe in He Yan lane, inclined gallery, also can cause inbreak ,Jiang Yan lane, tunnel operating personnel and wound or collide to death, cause the serious accident of personal injury.For the safe operation of the Inclined Lane Lifting that guarantees mine, a series of effective measures have been taked in each colliery, and wherein the application of stop device is exactly one of safety measure fruitful in " three fix four insurances ".
Existing coal mine sloping lane transportation adopts artificial foot-operated mode to open stop device, or, at the intracardiac embedding steel pipe of rail, carries out keeping off a car of inclined gallery grade change point by the interim round steel of placing in steel pipe.The above-mentioned mode of keeping off a car all needs manually closely to operate alley stopping device, is unfavorable for the personal safety of operating personal, and interim alley stopping device safety performance is lower, and personnel's operation labor intensity is large.
Summary of the invention
The Pneumatic car stopper that provides a kind of safety factor high, easy and simple to handle is provided the utility model purpose.
For achieving the above object, the utility model can be taked following technical proposals:
Pneumatic car stopper described in the utility model, comprise the support that bottom arranges; In described mid-stent, be provided with stop device, described stop device middle part is hinged with support, in support one side, be provided with cylinder, the piston rod end of described cylinder and described stop device bottom are hinged, and the admission port of cylinder is connected with compressed air inlet port by pipeline, is communicated with and is provided with control cock and filtering installation on described pipeline.
Described filtering installation is for being communicated with and being arranged on airfilter on pipeline, compression indicator and steam separator successively.
The utility model advantage is simple and safe operation, failure rate is low, the maintenance repair maintenance is little, expense is cheap, has improved inclined gallery transportation safety coefficient, has reduced worker's labour intensity.Adopted pressurized air as power, by control cock Long-distance Control cylinder, and the facilities such as airfilter, steam separator have been set up, pressurized air is filtered, avoided pneumatic facility to cause the sometimes fast and sometimes slow phenomenon of cylinder piston rod stretching speed because of foreign material in pressurized air more, reduce the fault rate of Pneumatic car stopper, ensured the normal safe operation of stop device and the personal safety of operating personal, greatly improved the safety factor of inclined gallery transportations.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, Pneumatic car stopper described in the utility model, comprise the support 1 that bottom arranges; At described support 1 middle part, be provided with stop device 2; described stop device 2 middle parts and support 1 are hinged; in support 1 one sides, be provided with cylinder 3; the piston rod end of described cylinder 3 and described stop device 2 bottoms are hinged; and the admission port of cylinder 3 is connected with compressed air inlet port by pipeline 4, is communicated with and is provided with control cock 5 and filtering installation on described pipeline 4; Described filtering installation is for being communicated with and being arranged on airfilter 6 on pipeline 4, compression indicator 7 and steam separator 8 successively.
Its principle of work is: when vehicle passed through stop device 2, personnel are operation control valve 5 in signal cabin, and cylinder 3 piston rods are stretched out, and promoted stop device 2 bottoms, made its stressed decline, and vehicle is passed through; After vehicle passed through, personnel's operation control valve 5, shrank cylinder 3 piston rods, makes the stressed rising of stop device 2, realizes stop device 2 closures, ensured the safe operation of mine inclined roadway transporting work.
Claims (2)
1. a Pneumatic car stopper, comprise the support (1) that bottom arranges; It is characterized in that: be provided with stop device (2) at described support (1) middle part, described stop device (2) middle part is hinged with support (1), in support (1) one side, be provided with cylinder (3), the piston rod end of described cylinder (3) and described stop device (2) bottom are hinged, and the admission port of cylinder (3) is connected with compressed air inlet port by pipeline (4), be provided with control cock (5) and filtering installation in upper connection of described pipeline (4).
