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 is connected on the suspension rod axle 42 of rotating mechanism by flat key 49 and stop nut 9； The lower end of suspension rod axle 42 is provided through the through hole 422 of diameter；Described stop nut and suspension rod axle are connected with bolt 99 again Come, and the bolt 99 passes through the diameter of stop nut and suspension rod axle.

Wherein, described stop nut 9 is cylindric that its center is provided with screw thread 91, and described stop nut external diameter opens up One through hole 92, multiple blind holes 93 are also opened up on described stop nut external diameter it is used to inserting lever and conveniently pull nut.

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, and running trolley can be run back and forth above girder, So the crane of the application not only can with the next door workshop goods of unloading cart traffic direction end points, and can unloading it is big The goods in car running track line side workshop；The lifting or decentralization goods for pulling ring-chain hoist (200) rely on and pull chain (201) Pulling function operated；By pulling the drive chain (61) pulled on sport car (6), the sprocket wheel pulled on sport car drive And vehicle wheel rotation, pull sport car so as to drive and moved back and forth along cantilever beam orbit；The drive chain in sport car is pulled by oblique pull In bar (61) or oblique pull hand draw ring chain block pull chain (201) can make cantilever beam rotate and can random angle rotation；Pass through Pull the chain (84) pulled in cart running gear that whole crane can be driven to be run back and forth along train track；Can be by upper The integrated motion stated, such as cart operation, cantilever beam rotates, and pulls sport car motion, ring-chain hoist hook lifting, running trolley fortune It is dynamic, just can object by pull driving from outdoors or the handling of next door workshop to workshop domestic demand will place, with workshop surrounding Next door workshop or workshop can need not borrow the transhipment of other transporting equipments, convenient working when carrying out goods handing-over outdoors, reduction is set Standby investment is cost-effective.

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 cantilever beam of the application crane also can reach next door workshop unloading goods among supporting rack (100).

In the case where manually pulling chain (710) effect, running trolley can be run running trolley along girder both ends in the application, It is adapted to large span workshop operation.

Gear device in the application on running trolley is arranged on trolley frame, followed by running trolley operation, knot Structure takes up space small, it is not necessary to which strainer, easy to operate, wheel is non-slip；Multiple tracks deceleration is provided with gear device Device, its middle sprocket A (72) and sprocket wheel B (73) can partner speed reducing ratio, gear (74) and the wheel on dolly driving wheel (31) Tooth partners speed reducing ratio, can so mitigate artificial pulling force significantly, and manpower pulls endless chain (710), makes chain pulley (71) light Pine rotates, and is especially suitable for the big running trolley of tonnage.

Wheel in the application on running trolley includes dolly driving wheel (31) and follower；In the application on running trolley Wheel can also all be driving wheel, the driving wheel of the same side two connects driving with chain again, this spline structure trolley travelling Can be more smooth, wheel will not skid, but complicated cost is high.

Track above the application middle girder uses inverted " u "-shaped track, and the wheel of running trolley is bushing to be run in orbit, This spline structure can effectively play anti-roll-over action to running trolley.

After the application cantilever member and suspension rod axis connection, then connected with suspension rod axle thread by stop nut, and have bolt (99) connected through the diameter of stop nut and suspension rod axle, avoid stop nut from loosening, securely and reliably, on stop nut Blind hole can facilitate lever to insert, and it is light to pull nut, easy disassembly and maintenance.
