The beneficial effect of the application is as described below：

The suspension hook on lifting truck (01) in the application can be usually used in this either inside cargo hoisting, because lifting cargo Center of gravity do not produce tilting moment in the underface of crane, crane and trolley, work can be improved using the operating mode of high speed Make efficiency, and available for lifting large-tonnage object；Lifting truck is acted on available for main lifting.

The cantilever beam in running trolley (3) in the application crane can be stretched out between crane locomotive to outdoors or to next door Workshop directly lifts cargo；The next door workshop cargo of cart traffic direction endpoint can be not only lifted by crane, and cart can be lifted by crane The cargo in running track line side workshop；Since the cantilever beam of the application is arranged at below trolley and girder, cantilever beam can pass through The direct lifting cargo in next door workshop is stretched into below support rail beam, or can directly stretch out the workshop operation outdoors of cart traffic direction, because This present techniques feature can realize the application purpose；After lifting cargo, by movement of the electric block along cantilever beam, or By the rotation of cantilever member, or the movement by running trolley, or the movement by crane, or pass through foregoing four Integrated motion, can hang onto the cargo of lifting in the place of this workshop needs；With next door workshop or workshop outdoors into crudely-made articles Thing can need not borrow the transhipment of other transporting equipments when joining, improve efficiency.

The suspension hook on lifting truck (01) in the application crane and electric block (10) suspension hook on running trolley (3) With the use of handling elongate article can be facilitated.

Electric frame (121) of choosing on the application loading bridge is equipped with two groups of moveable lashed cables (123), one group of connection lifting Trolley (01) is powered, another group of connection running trolley (3) power supply.

The cantilever crane of the application be suitable for workshop only have set up on the metope column of one side bracket be laid with track, another side Use the environment of workshop track；Cart actuating device is run on column track on end carriage in crane semi portal, on ground beam Cart actuating device run in the track of workshop；Cantilever beam can be reached among supporting rack next door workshop lifted or Unload cargo.

Running trolley (3) in the application can be moved back and forth in the top of girder along girder both ends, be suitable for greatly across Workshop is spent to use；Two anti-roller devices are respectively installed in running trolley both sides, can serve " safety hook ", in anti-roller devices Roller, which is pressed on rail, to be run, and can not only have been avoided cantilever beam from overloading and produced running trolley rollover and ensure that security, but also can protect Card running trolley on wheel all rail do not upwarp, it is ensured that running trolley is run always；It is suitable by adjusting adjust pad (337) Work as thickness, the roller in anti-roller devices is rightly connected with rail (22), rolling can be press against, ensure trolley Smooth, running trolley list driving is run, it is cost-effective in terms of trolley driving.

The application running trolley is driven using the drive car (32) of independent no mechanically contact, every on running trolley A adhesion wheel group is driven using independent, and power is strong；So component packet property is good, easy to installation and maintenance；The application trolley drives Use " three-in-one " gear reducer, small in volume, noise are small in dynamic device；Its output shaft is hollow shaft and wheel with spline It is easy that axis cooperation facilitates, and the horizontal space of its output shaft shared trolley frame vertical with motor shaft is small.

Be equipped with beside the girder of this crane walk on stage (23) maintenance personal can be facilitated to appear on the stage maintenance operation, maintenance is more convenient.

Anti- tipple in the application crane is installed on the both ends of end carriage, and wheel on end carriage is limited in by horizontal wheels Orbit centre is run, it is ensured that rail is not gnawed in crane operation；One of the advantages of this anti-tipple horizontal wheels are installed on engineer room (631) in, wheel shaft (62) both ends are all fixed in the through hole (632) of engineer room, and cantilever, wheel shaft can not bear big such horizontal wheels Lateral impact forces not flexural deformation；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, the wheel rim of horizontal wheels catches on running track at this time, 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；Since ground beam length is longer than end carriage, so being set on end carriage Put anti-tipple.

End carriage and ground beam both ends in the application crane all set cart actuating device, ensure that cart operation is smooth, keep away Because end carriage or ground beam may upwarp when exempting from unilateral driving, driving wheel not rail produce idle running phenomenon；The cart driving dress of the application (8) structure novelty is put, it is highly practical；The wheel body of connecting shaft wheel is once swaged into wheel shaft, simple in structure, is especially suitable for path car Wheel, it is that can stand very big axial float inner flange seat all without de- that the ring flange of inner flange seat, which is connected to benefit on the inside of end carriage, Off normal and put, the connection bolt of inner flange seat need not bear big axial tension, and wheel alignment is good；The output shaft of decelerating motor can To be flat key axis or splined shaft or double bond axis, according to torque different situations, rationally coordinate with wheel axis hole；Decelerating motor leads to Cross cushion pad to be connected on end carriage or ground beam, due to the cushioning effect of cushion pad, alleviate decelerating motor and start, brake to produce and rush Vibration is hit, protects driving device.

Bearing block and sunpender axis connection in the application rotating mechanism bear gravity by thrust bearing, and thrust bearing is installed on Bearing block top, it is easy to disassemble；The inner hole structure of bearing block is simply easy to process；Sleeve (43) makees sliding bearing for wear-resistant material Use, reduce the fit clearance of sunpender axis, increase rotational stabilization, increase the concentricity of driving 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；Drive in rotating mechanism Dynamic device output shaft is increased degree of flexibility, is improved between driving device and sunpender axis by shaft coupling (48) and sunpender axis connection Malalignment regulating power.

Rotary limit device (58) can be equipped between cantilever member and running trolley in the application, can so avoid cantilever Beam excessively rotates, i.e. no more than 360 degree angle rotations, prevents the cable (200) of electric block to be wrapped in cantilever member and pulled It is disconnected because the cable (200) of electric block be draw from the junction box on running trolley it is ensuing；Cantilever member connects with sunpender axis After connecing, after positioning is connected with sunpender axle thread by stop nut, then with bolt (99) through the straight of stop nut and sunpender axis Footpath connects, and avoids stop nut from loosening, securely and reliably.
