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 crane on workshop is hung from dolly carries out lifting goods, and dolly can only be along Crane twin beams is run back and forth, and crane can only be run back and forth along the cart track on the end bay post of workshop two, such crane The goods scope that suspension hook can lift 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 from far point outside this plane article (such as workshop outdoors, across It cannot lift, can only now be transported by other transporting equipments outside), workshop is generally driven under suspension hook by automobile and hung Loading thing, some cars are opened laterally lays track without coming between this workshop and next door workshop, allows trolley special to reach and hangs Hook gets off to join goods, and some sets up a special cantilever crane in workshop doorway (or workshop passageway), to the goods outside workshop It is transported through scheduling, first goods is lifted up into the place that this workshop crane suspension hook is got at, then again by crane this Goods handling is to the other stations in workshop, and the existing bridge crane that is used under this operating mode can not directly join with next door workshop Goods, must be by other transporting equipment schedule jobs, and it is quite inconvenient to bring, and also produces manpower and materials and wastes；Some grains having Crane requirement used in warehouse and the explosion-proof workshop article hoisting of industry electrically has explosion prevention function, it is necessary to fire-proof motor, explosion-proof Electric block cost is very high, and particularly tonnage is little, using the not high place of working level, uses anti-explosion electric lifting speculative investment Greatly, maintenance cost is high；Workshop also does not provide electric power, carries out Articles transfer by fork truck or manpower, 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 in no electric power Use or mustn't use under environment and used under the explosion-proof environment of electrical equipment；The crane not only can the operation in this workshop, Can also place be directly lifted by crane or discharge goods outdoors 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 master of an end carriage 2, supporting racks 100 of beam form, described two girders, one connection end carriage 1, 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 with 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 move back and forth along outrigger horizontal；It is described Pull suspension under sport car and pull ring-chain hoist 7；The cantilever beam is in below two girders and can stretch out operation outside workshop, And it can rotate.

Wherein, the described cart running gear 8 that pulls includes driving wheel A80, driving wheel 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 driving wheel A80 peaces Mounted in the other end of the grade beam；Described driving wheel B82 is arranged on the other end of the end carriage；The side of the driving wheel B Wheel rim is provided with gear；The driving wheel B is connected with the external toothing of gear shaft 85；The gear shaft passes through power transmission shaft A86 and bangle 83 one side are taken turns to connect；The bangle wheel is connected on support 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 passes through power transmission shaft B88 connections minor sprocket 89；The minor sprocket by roller chain 810 with Big sprocket wheel 811 connects；The big sprocket wheel is connected on above-mentioned driving wheel A80 wheel shaft；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 set One connecting hole 521, described connecting hole is interior to be provided with keyway 522；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 both ends are both provided with limiter 511。

The beneficial effect of the application is：

The crane of the application can under no electric power environmental or mustn't use electrical equipment explosion-proof environment under use, It is novel reliable；Because the cantilever beam of the application is arranged at below girder, 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) rely 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 drive Wheel rotates, and pulls sport car so as to drive and is moved back and forth along cantilever beam orbit；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；Pass through pulling The endless chain (84) pulled in cart running gear can drive whole crane to be run back and forth along train track；Can be by above-mentioned Integrated motion, as cart run, cantilever beam rotate, pull sport car motion, ring-chain hoist hook lifting, object can just be passed through It is local from handling outdoors to workshop domestic demand to pull type of drive, can need not borrow other when joining with goods outside workshop and reset Apply.

The crane of the application be suitable for workshop only have set up on the metope column of one side bracket laying track, another side use The environment of workshop track；Wheel is run 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 main on the speed ratio and grade beam of driving wheel B and gear shaft (85) on end carriage in cart running gear (8) The big sprocket wheel (811) of driving wheel A connections is more identical than being designed to the speed of minor sprocket (89), is so manually pulling endless chain (84) When, so that it may bangle wheel (83) rotation is drive, so as to drive driving wheel A, the operation of driving wheel B synchronous same-speeds；If unnecessary Human hand, can also boosting supporting rack operation, reduce the pulling force for pulling endless chain, 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 to borrow the transhipment of other crane gears outdoors during goods handing-over, improve efficiency, it is cost-effective to reduce equipment investment.

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