Description

A kind of semi portal crane for pulling driving

Technical field

The application is related to crane field, more particularly to a kind of semi portal crane for pulling driving.

Background technology

Existing bridge crane is applied in Workshop, and the product and raw material in workshop are required for Real-Time Transport to next door Workshop or other departments；The suspension hook of the crane on workshop is hung from dolly carries out lifting goods, and dolly can only be along Crane twin beams runs back and forth, and crane can only back and forth run along the cart track on the end bay post of workshop two, such crane The goods scope that suspension hook can be lifted is in this plane within the plane that the two-end-point of the two cart tracks in workshop is surrounded When the goods at edge needs lifting, suspension hook just produces oblique pull, then outside this plane far point article (as workshop outdoors, across Cannot lift outward), now generally workshop can only be driven into by automobile and hung under suspension hook by other transporting equipment transhipments Loading thing, some cars are opened to come in and track are just laterally laid between this workshop and next door workshop, allow trolley special to reach and hang Hook gets off and joins goods, and what is had sets up a special cantilever crane in workshop doorway (or workshop passageway), to the goods outside workshop Scheduling is transported through, first goods is lifted up into where this workshop crane suspension hook gets at, then again by crane this Goods handling can not directly join to other stations of workshop, the existing bridge crane used under this operating mode with next door workshop Goods, must bring quite inconvenience by other transporting equipment schedule jobs, also produce manpower and materials and waste；Some grains having Crane used by warehouse and industrial explosion-proof workshop article hoisting requires electrically there is explosion prevention function, needs fire-proof motor, explosion-proof Electric block cost is very high, and particularly tonnage is little, using the not high place of working level, using anti-explosion electric lifting speculative investment Greatly, maintenance cost is high；Workshop also does not provide electric power, and by fork truck or manpower Articles transfer is carried out, and labor intensity is excessive.

The content of the invention

The application purpose is to provide a kind of semi portal crane for pulling driving, and the crane can be without electric power Under environment using or mustn't use under the explosion-proof environment using electrical equipment；The crane not only can the operation in this workshop, Can also outdoors place be directly lifted by crane or discharge goods in this workshop in cart running track direction, it is not necessary to by other transporting equipments Transhipment scheduling goods.

To reach above-mentioned purpose, the application is realized using following technology：

A kind of semi portal crane for pulling driving, including semi portal 28, the semi portal is by 1, two masters of an end carriage 2, supporting rack 100 of beam is constituted, the connection end carriage 1 of two girders one, other end connection leg frame 100；The supporting leg Include grade beam 101 on frame；It is characterized in that：Described semi portal 28 is provided with and pulls cart running gear 8, and semi portal is movable； Two girders 2 overcentre is fixedly connected a beam platform 3；The Liang Tai is provided with rotating mechanism 4；In the rotating mechanism The upper end of suspension rod axle 42 be connected with rolling bearing 46, its lower end is connected with cantilever member 5；Cantilever beam 51 on the cantilever member Upper connection one pulls sport car 6 with drive chain 61；The sport car that pulls can be moved back and forth along outrigger horizontal；It is described Pull to be hung under sport car and pull ring-chain hoist 7；The cantilever beam is in two girders lower section and can stretch out operation outside workshop, And can rotate.

Wherein, the described cart running gear 8 that pulls includes drivewheel A80, drivewheel B82, follower 81, bangle wheel 83rd, endless chain 84, two followers 81 are separately mounted to one end of end carriage 1 and grade beam 101；Described drivewheel A80 peaces It is mounted in the other end of the grade beam；Described drivewheel B82 is arranged on the other end of the end carriage；The side of the drivewheel B Wheel rim is provided with gear；The drivewheel B is connected with the external toothing of gear shaft 85；The gear shaft is by power transmission shaft A86 and bangle Take turns 83 one side to couple together；The bangle wheel is connected on bracing frame 87 by bearing block, and support frame as described above is fixed on the side of girder 2 On face；The another side of the bangle wheel 83 connects minor sprocket 89 by power transmission shaft B88；The minor sprocket by roller chain 810 with Big sprocket wheel 811 connects；The big sprocket wheel is connected on the wheel shaft of above-mentioned drivewheel A80；Above-mentioned bangle wheel 83 connects one two The endless chain 84 that end seal is closed.

Wherein, described cantilever member 5 includes cantilever beam 51, Holder for hanging household utensiles 52, brace 53；The Holder for hanging household utensiles top is arranged One connecting hole 521, is provided with keyway 522 in described connecting hole；The Holder for hanging household utensiles bottom is provided with operation window 523；The hanging The lower weld of seat 52 welds above-mentioned oblique pull between one end of the cantilever beam 51, the other end and Holder for hanging household utensiles of the cantilever beam Bar 53 forms triangular structure；The cantilever beam is made up of I-steel or H profile steel；The cantilever beam two ends are both provided with stop 511。

The beneficial effect of the application is：

The crane of the application can mustn't be used under without electric power environmental or under the explosion-proof environment using electrical equipment, It is novel reliable；Because the cantilever beam of the application is arranged at girder lower section, cantilever beam can be directly stretched out between crane locomotive to outdoors Or to the direct unloading goods in next door workshop；The lifting or decentralization goods for pulling ring-chain hoist (7) relies on the drawing for pulling chain (71) Action is with being operated；By pulling the drive chain (61) pulled on sport car (6), the sprocket wheel and car pulled on sport car is drive Wheel is rotated, and is pulled sport car and is moved back and forth along cantilever beam orbit so as to drive；The drive chain in sport car is pulled by oblique pull (61) or in oblique pull hand draw ring chain block pull chain (71) can make cantilever beam rotate and can random angle rotation；By pulling Pulling the endless chain (84) in cart running gear can drive whole crane to run back and forth along train track；Can pass through above-mentioned Integrated motion, such as cart operation, cantilever beam rotates, and pulls sport car motion, and ring-chain hoist hook lifting can just pass through object Pull type of drive from handling outdoors to workshop domestic demand will place, reset with borrowing other and rise during goods handing-over in the workshop outside Apply.

The crane of the application be suitable for workshop only have on the metope column of one side set up bracket lay track, another side uses The environment of workshop track；Wheel runs on column track on end carriage in crane semi portal, and the wheel on grade beam is in workshop Run in track.

The application pulls the speed of drivewheel B and gear shaft (85) on end carriage in cart running gear (8) and compares and master on grade beam The big sprocket wheel (811) of driving wheel A connections is more identical than being designed to the speed of minor sprocket (89), so in artificial hand draw ring shape chain (84) When, so that it may bangle wheel (83) rotation is drive, so as to drive drivewheel A, the operation of drivewheel B synchronous same-speeds；If unnecessary Staff, it is also possible to which boosting supporting rack operation, reduces the pulling force for pulling endless chain, and crane operation is convenient.

The Liang Tai (3) of this crane is fixed on motionless on girder, is suitable for narrow workshop, with next door workshop or workshop Carry out that outdoors the transhipment of other crane gears can be borrowed when goods joins, improve efficiency, reduce equipment investment cost-effective.

Brace in the application cantilever member and cantilever beam and Holder for hanging household utensiles composition triangular structure, make cantilever member rigidity By force, good stability, the advantages of load-carrying is big.
