Abstract
The invention discloses a lifting-type gas detector, relates to a combustible gas detection device, and solves the problems that because a gas detector in the prior art is arranged in a fixed position, the gas detector position is difficult to change and the maintenance is inconvenient, the lifting-type gas detector includes an AC (alternating current) motor, a reducer, a winch, a steel wire rope, a detector mounting rack and a gas detector, the output end of the AC motor the is connected to the input end of the reducer, a rotating shaft of the winch is connected with the output end of the speed reducer, one end of the steel wire rope is wound on the winch, the other end of the steel wire rope is fixedly connected with the top of the detector mounting rack, and the bottom of the detector mounting rack is fixedly connected with the gas detector. The lifting-type gas detector is applicable to the combustible gas detection device.
Description
Technical field
The present invention relates to combustible gas detecting device.
Background technology
At present, in some industrial and mining enterprises, the top in factory building may be assembled as the low gas of ratio atmospheric density of hydrogen etc., will produce blast when such gas reaches finite concentration; Or poisonous, the harmful gas of pinnacled gas pipe line seam crossing or damp leak.These places generally all need installing gas detector, whether gas are existed and are overflowed and monitor.
The way of taking is at present generally stationary detector to be installed to pinnacled fixed position monitor.But such mode has its drawback, be exactly that detector General Requirements is once demarcated to year half a year.Need people to operate or detector is disassembled and demarcated to eminence.Such operation danger close and operation easier are very high.
Summary of the invention
The position that the object of the invention is to be arranged in order to solve existing gas detector the existing gas detector in fixed position is difficult to change and the problem of repair and maintenance inconvenience, and a kind of elevation type gas detector is provided.
Elevation type gas detector, it comprises alternating current generator, reductor, capstan winch, wire rope, detector erecting frame and gas detector, the output terminal of alternating current generator is connected to the input end of reductor, the rotating shaft of capstan winch is connected to the output terminal of reductor, one end of wire rope is wrapped on capstan winch, the other end of wire rope is fixedly connected on the top of detector erecting frame, and the bottom of detector erecting frame is fixedly connected with gas detector.
The present invention is connected gas detector by wire rope with capstan winch, by alternating current generator, reductor, drive capstan winch to rotate; When needs change gas detector height, by capstan winch, rotate the up/down lifting that realizes gas detector, thereby realize the change of the detecting location of gas detector, and then realize the detection of gas of optional position and be convenient to patrol and examine and the operation such as debugging.
Accompanying drawing explanation
Fig. 1 is scheme of installation of the present invention.
Embodiment
embodiment one:in conjunction with Fig. 1, present embodiment is described, elevation type gas detector described in present embodiment, it comprises alternating current generator 1, reductor 2, capstan winch 3, wire rope 4, detector erecting frame 6 and gas detector 7, the output terminal of alternating current generator 1 is connected to the input end of reductor 2, the rotating shaft of capstan winch 3 is connected to the output terminal of reductor 2, one end of wire rope 4 is wrapped on capstan winch 3, the other end of wire rope 4 is fixedly connected on the top of detector erecting frame 6, and the bottom of detector erecting frame 6 is fixedly connected with gas detector 7.
embodiment two:in conjunction with Fig. 1, present embodiment is described, present embodiment is the further restriction to elevation type gas detector described in embodiment one, and alternating current generator 1 adopts explosion-proof alternating current generator.
Described explosion-proof alternating current generator, controls by control circuit, can manual adjustments detector height.And there is travel switch and carry out spacingly, can limit extreme higher position and the extreme lower position of gas detector.
embodiment three:in conjunction with Fig. 1, present embodiment is described, present embodiment is the further restriction to elevation type gas detector described in embodiment one, and it also comprises electromagnetic clutch, and electromagnetic clutch is serially connected between reductor 2 and capstan winch 3.
The present invention can drop to common motor speed by reductor the manual manipulation that a lower speed is convenient to people.Electromagnetic clutch can, when motor or reductor break down, prevent that detector from, from falling, playing self-lock protection effect in the air.
embodiment four:in conjunction with Fig. 1, present embodiment is described, present embodiment is the further restriction to elevation type gas detector described in embodiment one, it also comprises wire rope fixture 5, the other end of wire rope 4 is fixedly connected with detector erecting frame 6 by wire rope fixture 5, and wire rope fixture 5 is comprised of retainer clip and universal hook.
embodiment five:in conjunction with Fig. 1, present embodiment is described, present embodiment is the further restriction to elevation type gas detector described in embodiment one, the stainless steel wire rope that wire rope 4 adopts with plastic cement adventitia.
During concrete application: when needs change gas detector position, can control alternating current generator 1 work, rolling or emit wire rope 4 and realize the positions that automatically change gas detector 7.Also can manual adjustments detector height, realize the semiautomatic change that realizes gas detector 7 positions.
The invention solves gas detector at specific area, such as oil-gas field surface engineering, oil refining, chemical industry, coal etc., cannot realize the defects such as safe and efficient running.Have any change gas detector position height, be convenient to the advantages such as maintenance and debugging.
