Abstract
The utility model discloses an in-tank pneumatic car stopper which comprises a car stop claw fixed on a track, and a power control device used for driving the car stop claw to open and close, wherein the power control device comprises a connecting rod; the upper end of the connecting rod is connected with the car stop claw; the lower end of the connecting rod is connected with a rotating shaft in a transmission way, and one end of the rotating shaft has a crank structure; a push plate driven by a cylinder is arranged at the position corresponding to a crank; the rear end of the car stop claw is provided with a reset spring; a piston rod end of the cylinder is fixedly connected with the center position of the push plate; and the push plate is formed by two symmetrical plates. The in-tank pneumatic car stopper has the advantages of being simple in structure, convenient to use and high in anti-explosion safety, and improving the degree of automation and the working efficiency; and the in-tank pneumatic car stopper is in-place and accurate in stroke and moderate in speed, increases the running efficiency of a cage, is time-saving and labor-saving, and lightens the labor intensity of workers.
Description
Technical field
The utility model relates to the In-pot Car Retarder used in the auxiliary shaft cage of colliery, especially relates to Pneumatic car stopper in a kind of tank.
Background technology
Cage is the key equipment of contact aboveground down-hole outlet in the coal mine lifting system, and stop device is set in cage be mainly to prevent that cage mine car in lifting process from vertically jumping.At present, the stop device structure of installing in domestic auxiliary shaft cage is varied, mainly contains Manual vehicle-blocking apparatus, electric vehicle arrester, hydraulic car stopper etc.Manual vehicle-blocking apparatus needs the lander to advance into cage unloading, move opening handle, manually In-pot Car Retarder is opened, after mine car goes out tank, again entered cage, with handle by its closure, this stop device adopts artificial the switching, and operating difficulties, waste time and energy, and operation is loaded down with trivial details, operating efficiency is low, dangerous when the lander enters cage at every turn; Electric vehicle arrester is to utilize storage battery power supply, DC machine drives the transmission shaft running, the motor forward can realize that In-pot Car Retarder opens, and motor reversal can make In-pot Car Retarder close, and this In-pot Car Retarder complex structure, battery altering is frequent, trouble point is many, explosion-proof performance is poor; Hydraulic car stopper adopts behaviour's car stop device principle of work, the stop device mechanism of one cuff horizontal drive shaft is installed in cage, increase simultaneously a retracing spring, with the journal stirrup of horizontal drive shaft, be connected, the closure of In-pot Car Retarder is realized by the elastic force of retracing spring, the unlatching of stop device is power output element by the push pedal of hydraulic actuating cylinder front end, and this In-pot Car Retarder structure is comparatively complicated, maintenance is large.
Summary of the invention
It is a kind of simple in structure that the utility model purpose is to provide, and opening and closing reliable is time saving and energy saving, the interior Pneumatic car stopper of the tank that safety performance is high.
For achieving the above object, the utility model can be taked following technical proposals:
Pneumatic car stopper in tank described in the utility model, comprise the fixing pawl and drive the power control unit that the described pawl of holding up traffic opens and closes of holding up traffic in orbit, described power control unit comprises the connecting rod that its upper end is connected with the pawl of holding up traffic, described connecting rod lower end is connected with the turning cylinder that an end is crank structure, at described crank correspondence position, be provided with the push pedal of air cylinder driven, be provided with retracing spring in the described pawl rear end of holding up traffic.
The rod end of described cylinder is fixedly connected with the center of push pedal, and described push pedal is comprised of two blocks of symmetrical plates.
The utility model advantage is simple in structure, easy to use, and explosion-proof security is high, degree of automation and work efficiency have been improved simultaneously, in this tank, the Pneumatic car stopper Overstroke is accurate, speed is moderate, has improved the efficiency that cage moves, time saving and energy saving, reduces worker's labour intensity.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model open and-shut mode schematic diagram.
The specific embodiment
As Fig. 1, shown in 2, Pneumatic car stopper in tank described in the utility model, comprise the pawl 2 and drive the power control unit that the described pawl 2 of holding up traffic opens and closes of holding up traffic be fixed on track 1, described power control unit comprises the connecting rod 3 that its upper end is connected with the pawl 2 of holding up traffic, described connecting rod 3 lower ends are connected with the turning cylinder 5 that an end is crank 4 structures, at described crank 4 correspondence positions, be provided with the push pedal 7 that cylinder 6 drives, in described pawl 2 rear ends of holding up traffic, be provided with retracing spring 8, the rod end of described cylinder 6 is fixedly connected with the center of push pedal 7, described push pedal 7 is comprised of two blocks of symmetrical plates.
During use, after cage 9 put in place, cylinder 6 piston rods stretched out, and drove push pedal 7 throw cranks 4, made turning cylinder 5 rotations, and then drivening rod 3 rotations, thus the pawl 2 that makes to hold up traffic open, car puller promotes mine car and enters cage 9; After mine car enters cage 9, press the control button of dynamic air cylinder 6, the electromagnetic switch valve events, the source of the gas commutation, piston rod is retracted, and the pawl 2 of holding up traffic sets back by rear end retracing spring 8, and mine car axle 10 in cage is stopped.
Claims (2)
1. Pneumatic car stopper in a tank, comprise the pawl of holding up traffic (2) be fixed on track (1) and drive the power control unit that the described pawl of holding up traffic (2) opens and closes, it is characterized in that: described power control unit comprises the connecting rod (3) that its upper end is connected with the pawl of holding up traffic (2), described connecting rod (3) lower end is connected with the turning cylinder (5) that an end is crank (4) structure, at described crank (4) correspondence position, be provided with the push pedal (7) that cylinder (6) drives, be provided with retracing spring (8) in the described pawl of holding up traffic (2) rear end.
