The beneficial effect of the application is as described below：

Cantilever beam in the application crane can be stretched out between crane locomotive to directly lifting goods outdoors or to next door workshop Thing；The next door workshop goods of cart traffic direction end points can be not only lifted by crane, and cart running track line side can be lifted by crane The goods in workshop；Because the cantilever beam of the application is arranged at below suspension end carriage dolly and girder, cantilever beam can pass through support rail beam The direct lifting cargo in next door workshop is stretched into lower section, or can directly stretch out the workshop operation outdoors of cart traffic direction, because generally The door top in workshop can reach height where the support rail beam in this workshop substantially, therefore present techniques feature can realize the application mesh 's；After lifting goods, by motion of the electric block along cantilever beam, or the rotation by cantilever member, or pass through suspended end The movement of beam dolly, or the motion by crane travelling mechanism, or by foregoing four integrated motion, can be lifting Goods hang onto this workshop needs place；Can when carrying out goods handing-over outdoors with the next door workshop of workshop surrounding or workshop The transhipment of other transporting equipments need not be borrowed, improves efficiency.

Running track (21) is set below the girder in the application crane, and suspension end carriage dolly is suspended on girder track On, its installing space position is reduced, is particularly suitable for roofing with crane apart from small workshop.

Anti- tipple in the application crane is arranged on two of end carriage, it is ensured that and rail is not gnawed in crane operation, It is especially suitable for large span crane；Horizontal wheels in anti-tipple carry wheel rim, can serve " safety hook ", may be because outstanding Arm load beam is overweight, and for crane end carriage while upwarping, now the wheel rim of horizontal wheels catches on running track, avoids crane from tumbling, Ensure safety；Can be rotated in the same old way while horizontal wheels catch on track, crane can run advance in the same old way, this technology use than The safety hook of steel plate type is advanced, and stuck phenomenon does not occur for cart operation.

End carriage both ends in the application crane all set cart actuating device, ensure that cart operation is smooth, avoid unilateral Because end carriage may upwarp during driving, driving wheel not rail produce idle running phenomenon；Cart actuating device (8) structure of the application is new It is clever, compact, assembly and disassembly it is convenient；Hollow flange axle is hollow, and drive shaft passes therethrough；Ring flange (851) on hollow flange axle Both it had been used to connect end carriage, and had been used to connect reducing motor again, positions reducing motor；The output shaft of reducing motor passes through hollow flange axle Hollow hole is connected with wheel spline pair and directly drives wheel；Positioning concave ring on reducing motor is snugly connected to hollow In the flange external diameter of flange shaft, the connecting hole on reducing motor flange seat passes through with the motor connection screw on hollow flange axle Bolt is tightly coupled together；The reducing motor of this structure is especially adapted to planetary reduction gear, and structure is small, and noise is small；So slow down electricity Connect not only simple but also firmly between machine and wheel, axiality is good, takes up space small, ensures that wheel steadily operates, operate it is with small vibration, Noise is small.

The driving wheel in suspension end carriage dolly (3) drive mechanism in the application is enclosed on the edge of track (21) both sides Ji, is protected Card dolly does not drop, so as to ensure that crane is safe to use；A pair of driving wheels are all driven by motor, and the driving force of operation is big, are passed It is good to pass power effect；Hang and two sets of drive mechanisms are set on end carriage, being advantageous in that can avoid single driving from being possible to because of dolly on one side Somewhat upwarp adhesion wheel not rail and it is caused can't run phenomenon, dual drive ensures that trolley travelling is smooth；Hang end carriage dolly With electric block and rotating mechanism needed for power supply by lashed cable (123), along choosing on electric frame, cable wire rail (124) can be with suspension End carriage dolly runs power supply back and forth；Cable wire rail both ends are connected to two and choose electric frame (121), and the appropriate of electric frame is chosen by adjustment Highly, can solve lashed cable and most preferably hang position；Cable wire rail is to make track using steel wire rope, and cost is low.

Drive mechanism is arranged on inside suspension end carriage in the application, and suspension end carriage is overall high when being connected with the track under girder Spend small, so entirely suspension end carriage dolly swings small, stablizes；The anti-roller devices set on trolley frame can limit suspension end carriage While the degree upwarped, the roller in anti-roller devices can be pressed in below track (21) dolly, on counter suspension end carriage dolly Stick up, it is smooth so as to keep trolley travelling to stablize.

Car bumper on the application middle girder track can limit the stroke of suspension end carriage dolly, increase safety.

Cantilever beam (51) in the application cantilever member is fixedly connected with buffer (511) in that end in Holder for hanging household utensiles (52), rises slow Punching and the effect of spacing electric block；An adjustable car bumper device in position (70) is connected in the cantilever end of cantilever beam, its effect is Buffer on car stop can avoid electric block from moving back and forth impact or overtravel operation, the position of this car bumper device along cantilever beam Put flexibly it is adjustable, its benefit be according to the goods size cases lifted, can flexible modulation car bumper device fixed position, its essence It is the effective breadth for adjusting cantilever beam, small tonnage amplitude can be big, and large-tonnage is with by a small margin；Crane effectively is utilized, is ensured simultaneously Safety.

Be provided with rotary limit device between cantilever member in the application and suspension end carriage dolly, by safety ruler (583) and Two travel switch (581) compositions, safety ruler are arranged on suspension rod axle upper end, and travel switch is arranged on trolley frame upper surface, more square Just installation and adjustment；There is rotary limit device, cantilever beam can be avoided excessively to rotate, prevent the cable (100) of electric block from winding It is torn on Holder for hanging household utensiles (52) in cantilever member, because the cable (100) of electric block is from the wiring on trolley frame Case draws ensuing.

Have the gear auxiliary driving of a pair of elevating arcs transmission in rotating mechanism in the application crane, by big elevating arc, The different numbers of teeth setting of small elevating arc, can meet precise requirements of the user to the cantilever beam rotary speed of crane, avoid directly Selection standard reductor it is general speed than and caused cantilever beam rotating speed and the larger error of actual demand；Passed using elevating arc It is dynamic, the drive device in rotating mechanism can be made to use horizontal speed-reducer, reduce setting height(from bottom).

Bearing block and suspension rod axis connection in the application rotating mechanism bear gravity by thrust bearing, and thrust bearing is arranged on Bearing block top, it is easy to dismount；The inner hole structure of bearing block is simply easy to process；Sleeve (43) is that high-abrasive material makees sliding bearing Use, reduce the fit clearance of suspension rod axle, increase rotational stabilization, increase the axiality of drive mechanism, cantilever member, which rotates, to be saved Power；Stop nut A band dust covers (441) give bearing proofing dust and protecting, while can seal the butter in bearing；Stop nut A is with hanging After bar axis connection, then the connection by bolt (46), anti-loose effect is played, ensures rotating mechanism safety.

After cantilever member and suspension rod axis connection in the application, after connecting positioning with suspension rod axle thread by stop nut, Connected again with the diameter of bolt (99) through stop nut and suspension rod axle, avoid stop nut from loosening, securely and reliably.
