Abstract
Disclosed is a pneumatic or automatic mine cage curtain device used in a mine cage, which belongs to a protective device for a mine cage gate in a mine shaft lifting system. The curtain device is composed of a cage curtain, slipping rods, slipping sets, a curtain-carrying bar, a curtain-carrying hook, a traction rope, a pulling rope, a traction wheel and a directive wheel. The slipping sets are sleeved on the slipping rods, a pulling rope is provided between the slipping rods at both ends. The cage curtain is positioned on the pulling rope. The slipping sets are connected with the curtain-carrying bar, the curtain-carrying hook and the traction wheel. The directive wheel is connected at the upper end of the slipping rod and the traction rope is connected between the traction wheel and the directive wheel. The cage curtain is arranged in the front of the mine cage and is driven by a hauling wire rope of an air cylinder with the compressed air is used as a power source. The hauling wire rope of the air cylinder drives the cage curtain to complete the lifting process of the cage curtain. The automatic cage curtain device lights up the wellhead safety device, promotes the scientific and technological innovation of enterprises, elevates mechanized production level of enterprises, lessens the labor intensity of workers, improves the working environment of the workers and rewrites the history of manned cage curtain on mines.
Description
Technical field
The utility model relates to a kind of fender guard of mine vertical shaft elevator system cage gate, and particularly a kind of cage is with pneumatic automatic jar curtain door gear.
Background technology
At present, in the coal mine shaft lining elevator system, cage is the main transportation device of going into the well on the transportation work personnel, though the form of cage safety door is from experience improvement for several times till now in the early days of foundation, always be artificial jar of curtain door of employing, do not have fundamental change, artificial jar of curtain door is exactly that the workman is by artificial method switch jar curtain door, the mechanization level is low, and working strength of workers is big.
Summary of the invention
The purpose of this utility model is that a kind of mechanization level height will be provided, and the little cage of working strength of workers is with pneumatic automatic jar of curtain door gear.
The purpose of this utility model is achieved in that this curtain door gear has a jar curtain, slide bar, sliding sleeve, chooses curtain rod, chooses curtain hook, hauling rope, guy wire, traction wheel and track adjusting wheel, sliding sleeve is socketed on the slide bar, between the slide bar of two ends, guy wire is arranged, the jar curtain is through on the guy wire, on sliding sleeve, be connected with and choose curtain rod, choose curtain hook and traction wheel, upper end at slide bar is connected with track adjusting wheel, is connected with hauling rope between traction wheel and track adjusting wheel.
Described jar of curtain has cross bar, the annulus at the cross bar two ends, and this annulus is an elliptical ring, is connected with check chain anchor on cross bar, and two outer ends of the elliptical ring of a cross bar of lowermost end respectively have a quarter butt, and the front end of quarter butt is bent downwardly.
Described sliding sleeve is two parallel sliding sleeving holes, between two sliding sleeves connecting panel is arranged, and connecting panel one end flushes with sliding sleeve, and the other end is lower than sliding sleeve, and pin-and-hole is arranged on connecting panel.
Described interposition of choosing curtain rod is for circular, and two ends are taper shape, and a coupling link is at one end arranged; The described curtain hook of choosing at one end is converted into hook-shaped for circular.
Beneficial effect: owing to adopt such scheme, a jar curtain is installed before cage,, is used the reservoir haulage cable to drive a jar curtain, finish the lifting process of jar curtain to press wind as propulsion source; Uphill process: cage arrives wellhead platform, presses a jar curtain rising button, and control slide conversion wind path is to the reservoir air feed, and the piston rod of reservoir begins to shrink, and will choose the curtain rod pull-up by haulage cable, chooses curtain rod continuation rising the jar curtain is held up; Decline process: press a jar curtain decline button, control slide conversion wind path is to the reservoir air feed, the piston rod of reservoir begins to stretch out, and drives haulage cable by sliding sleeve and the deadweight of choosing curtain rod and falls, and a jar curtain is transferred thereupon, when sliding sleeve arrives lower limit, it is sagging by deadweight to choose curtain rod, tightens up haulage cable simultaneously, mechanization level height, working strength of workers is little, has reached the purpose of this utility model.Automatically jar curtain door gear brightening the well head safe facility, promoted Technology Innovation for Enterprise, promoted enterprise's mechanization production level, alleviate working strength of workers, improve the workman operating environment, rewritten and manually drawn jar history of curtain door.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
Fig. 2 is the side-looking constructional drawing of figure.
Among the figure, 1, slide bar; 2, guy wire; 3, jar curtain; 4, elliptical ring; 5, check chain anchor; 6, sliding sleeve; 7, track adjusting wheel; 8, hauling rope; 9, choose curtain rod; 10, choose the curtain hook; 11, traction wheel;
The specific embodiment
Embodiment 1: this curtain door gear has jar curtain 3, slide bar 1, sliding sleeve 6, chooses curtain rod 9, chooses curtain hook 10, hauling rope 8, guy wire 2, traction wheel 11 and track adjusting wheel 7, sliding sleeve is socketed on the slide bar, between the slide bar of two ends, guy wire is arranged, the jar curtain is through on the guy wire, on sliding sleeve, be connected with and choose curtain rod, choose curtain hook and traction wheel, upper end at slide bar is connected with track adjusting wheel, is connected with hauling rope between traction wheel and track adjusting wheel.
Described jar of curtain has cross bar, the annulus at the cross bar two ends, and this annulus is an elliptical ring 4, is connected with check chain anchor 5 on cross bar, and two outer ends of the elliptical ring of a cross bar of lowermost end respectively have a quarter butt, and the front end of quarter butt is bent downwardly.
Described sliding sleeve is two parallel sliding sleeving holes, between two sliding sleeves connecting panel is arranged, and connecting panel one end flushes with sliding sleeve, and the other end is lower than sliding sleeve, and pin-and-hole is arranged on connecting panel.
Described interposition of choosing curtain rod is for circular, and two ends are taper shape, and a coupling link is at one end arranged; The described curtain hook of choosing at one end is converted into hook-shaped for circular.
Principle of work: a jar curtain door is to press wind as propulsion source, to adopt the method for reservoir haulage cable drive actuating unit, to finish the lifting task of jar curtain; Uphill process: cage arrives wellhead platform, presses jar curtain rising push button control guiding valve conversion wind path to the reservoir air feed by full-time operative employee, and the air-cylinder piston bar begins to shrink, and will choose the curtain rod pull-up by haulage cable, chooses curtain rod continuation rising the jar curtain is held up; Decline process: press jar curtain decline push button control guiding valve conversion wind path to the reservoir air feed by full-time operative employee, the air-cylinder piston bar begins to stretch out, driving haulage cable by sliding sleeve and the deadweight of choosing curtain rod falls, the jar curtain is transferred thereupon, when sliding sleeve arrives lower limit, it is sagging by deadweight to choose curtain rod, tightens up haulage cable simultaneously.
