Wherein, the described cart running gear 8 that pulls includes driving wheel 82, follower 81, sprocket wheel 83, chain 84, two The follower 81 is separately mounted to one end of two end carriages 1；Driving wheel 82 described in two is separately mounted to two ends The other end of beam, a side flange of the driving wheel are provided with gear；The driving wheel is connected with the external toothing of gear shaft 85；Two The gear shaft is connected by power transmission shaft 86 and sprocket wheel 83 respectively；The sprocket wheel both sides are connected to bearing block and support frame 87 On, support frame as described above is fixed on girder 2；Described sprocket wheel connects a chain 84 closed at both ends.

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 be easy to rotation process.

Wherein, described safety hook 11 includes hooking seat 111, hooks body 112；The hook seat is provided with mounting hole 1111 and is used to connect It is connected on end carriage；Above-mentioned hook body is provided with eave tile 1121；The hook body is welded on the hook seat, and hooks seat vertically； Described eave tile 1121 is connected with the lower surface gap of the Ji edge of 12 upper cover plate of cart support rail beam 121.

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 directly lift goods to next door workshop；The lifting or decentralization goods for pulling ring-chain hoist (200) rely on and pull chain (201) Pulling function is operated；By push-and-pull hanging object steel cable or pulling chain (201) makes coaster be moved back and forth along cantilever beam orbit； By in oblique pull hand draw ring chain block pull chain (201) can make cantilever beam rotate and can random angle rotation；Pass through pulling The 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, such as cart operation, cantilever beam rotates, sport car motion, ring-chain hoist hook lifting, running trolley motion, just energy handle Object by pull type of drive from outdoors or the handling of next door workshop to workshop domestic demand will place, in the next door car with workshop surrounding Between or workshop the transhipments of other transporting equipments can need not be borrowed when carrying out goods handing-over outdoors, convenient working, reduce equipment investment It is cost-effective.

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 shaft (74) with dolly driving wheel (31) The gear teeth partner speed reducing ratio, can so mitigate artificial pulling force significantly, and manpower pulls endless chain (710), makes chain pulley (71) Ease rotation, it 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.

Brace (53) and cantilever beam and Holder for hanging household utensiles composition triangular structure in the application cantilever member, make cantilever member Rigidity is strong, stability is good, load-carrying is big, with material it is few the advantages that.

End carriage both sides in the application crane all set safety hook (11), crane can be avoided to tumble, and ensure safety；When When cantilever beam overloads, for end carriage while upwarping, now the eave tile of safety hook can catch on the upper cover plate Ji edge of cart support rail beam (12), keep away Exempt from crane to tumble, ensure safety；When crane tumbles trend, safety hook works, by swinging cantilever beam or movement The position of ring-chain hoist is pulled, changes position of the center of gravity of goods in crane, so as to recover the normal work of crane, does not incline Turn over.

Rolling bearing is connected between bearing block and suspension rod axle in the application rotating mechanism, so as to ensure hinged cantilever structure Part is laborsaving.
