Abstract
The invention relates to the field of bridge lifting machinery, in particular to a bridge crane crab with an infrared alarm. The bridge crane crab comprises a brake, a speed reducer, a transmission shaft, a half-tooth coupling, a motor, a roller set, a bearing, a small frame, infrared alarm probes, a balance pulley, a pulley set, a lifting hook and a steel wire rope; two infrared alarm probes are arranged at the lower end of the small frame; the infrared alarm has the following effects: when a lifted object performs an ascending, descending or translational motion, the infrared alarm probes induce if persons are below the lifted object or approach the lower side of the lifted object; if so, the infrared alarm gives an alarm to prompt the persons to leave from the area rapidly; when the persons are below a material or approach the lower side of the material in lifting of the material by a crane, the infrared alarm can give an alarm to prompt workers to leave rapidly to reach a safe area, so that the personal safety of the workers is guaranteed, and the accident rate is reduced; and the bridge crane crab has such advantages as simple structure, reasonable setting and low production cost.
Description
Technical field
The present invention relates to overhead traveling crane machinery field, be specifically related to a kind of crane in bridge type crane carriage with IR intrusion detector.
Background technology
Crane in bridge type uses the most extensive, owning amount is maximum a kind of orbital motion formula hoisting crane, and its rated load weight is from several tons to hundreds of ton.The most basic form is universal lifting hook crane in bridge type.
Crane in bridge type is a kind of crane span structure type hoisting crane that crane span structure runs on aerial conveyor, also known as overhead traveling crane.The crane span structure of crane in bridge type along be laid on both sides overhead on track longitudinally run, crane carriage laterally runs along the track be laid on crane span structure, form the operating range of a rectangle, just can make full use of the space handling material below crane span structure, not by the obstruction of wayside equipment.
Crane in bridge type is widely used in the places such as indoor and outdoor warehouse, factory building, harbour and outdoor yard.Crane in bridge type can be divided into ordinary bridge crane, simple and easy fine strain of millet crane in bridge type and three kinds, the special crane in bridge type of metallurgy.
Ordinary bridge crane is generally made up of crane carriage, crane span structure operating unit, crane span structure metal construction.Crane carriage again by lifting mechanism, wheeling mechanism and trolley frame three part form.Lifting mechanism comprises electrical motor, drg, retarder, reel and assembly pulley.Electrical motor, by retarder, drives spool turns, steel rope is put down around coiling or from reel, to be elevated weight.Trolley frame is rest and the frame of installing the parts such as lifting mechanism and wheeling mechanism, is generally welded structure.
But we usually see such news: hoisting crane because the reasons such as wire cable rupture, workman's violation operation cause material landing when handling material, kills and injures people by a crashing object.And current a lot of workshop, in driving operational process, still there is a lot of workman to walk below the material of handling, add the incidence of accident.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, the crane in bridge type crane carriage of the band IR intrusion detector providing a kind of structure simple, reasonable in design, easy to use, it can when crane for hoisting material, someone just reports to the police below material or close to time below material, remind workman lose no time away from, arrive safety zone, ensure that the personal safety of workman, reduce accident rate.
For achieving the above object, the technical solution used in the present invention is: it comprises drg, retarder, transmission shaft, half gear coupling, electrical motor, reel group, bearing, trolley frame, infrared alarm probe, equalizer pulley, assembly pulley, suspension hook, steel rope; Described drg, half gear coupling, electrical motor are all assemblied on a transmission shaft; Described reel group, bearing assemble are on another root transmission shaft; Described retarder connects two transmission shafts; The two ends of described steel rope are connected with reel group; The assembly pulley told is connected by wire rope gearing with equalizer pulley; Described equalizer pulley connects trolley frame; Two infrared alarm probes are provided with bottom described trolley frame; Described suspension hook is connected with assembly pulley.
Its principle of work is: the staff in driver's cab opens crane in bridge type starting switch, and press the alarm host machine switch of IR intrusion detector, now infrared alarm probe is started working, drg is opened, electrical motor energising produces electromagnetic torque, by half gear coupling, transmission shaft by transmission of torque to the high speed shaft of retarder, after gear transmission reducing, by retarder, torque is exported, and take over through fluted disc, band movable reel group rotates in fixed axis, steel rope fixed thereon is done around entering or laying out motion, corresponding rising or descending motion is done to the suspension hook that assembly pulley connects, then rising or the descending motion of hanging thing can be realized, drg realizes braking when being used for power-off.
The effect of IR intrusion detector is: when hang thing do rise, descending motion or motion of translation time, whether the induction of infrared alarm probe is hung has people or has personnel close below thing, when have people or have personnel close to time, IR intrusion detector then sends warning, and prompting personnel lose no time away from this region.
After adopting said structure, beneficial effect of the present invention is: the crane in bridge type crane carriage of band IR intrusion detector of the present invention, it can when crane for hoisting material, someone just reports to the police below material or close to time below material, remind workman lose no time away from, arrive safety zone, ensure that the personal safety of workman, reduce accident rate, and have structure simple, arrange rationally, the advantage such as cost of manufacture is low.
