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 dolly and girder, cantilever beam can be by stretching into below support rail beam The direct lifting cargo in next door workshop, or the workshop operation outdoors of cart traffic direction can be directly stretched out, because the generally door in workshop Top can reach height where the support rail beam in this workshop substantially, therefore present techniques feature can realize the application purpose；Lifting After goods, pass through motion of the electric block along cantilever beam, or the rotation by cantilever member, or the shifting for passing through underslung trolley It is dynamic, or the motion by crane travelling mechanism, or by foregoing four integrated motion, the goods of lifting can be hung The place needed to this workshop；It can need not be borrowed when carrying out goods handing-over outdoors with the next door workshop of workshop surrounding or workshop The transhipment of its transporting equipment, improve efficiency.

Trolley track (21) is set below the girder in the application crane, and underslung trolley is suspended on girder track, made Its installing space position reduces, and 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 Grain husk, it is practical；The wheel body of connecting shaft wheel is once swaged into wheel shaft, simple in construction, is especially suitable for path wheel, inner flange seat It is that can stand very big axial float inner flange seat all without departing from position, inner flange that ring flange, which is connected to benefit on the inside of end carriage, The connecting bolt of seat need not bear big axial tension, and wheel alignment is good；The output shaft of reducing motor can be flat key axle or Splined shaft or double bond axle, according to torque different situations, rationally coordinate with wheel axis hole；Reducing motor is connected by cushion pad On end carriage, due to the cushioning effect of cushion pad, alleviate reducing motor and start, brake generation impact shock, protect driving Device.

Underslung trolley (3) in the application can move back and forth along girder both ends, be suitable for big width workshop and use；Suspension Drive mechanism (34) on dolly can be in whole set procurement standarized component on the market, supporting facility；Driving wheel, quilt in drive mechanism Driving wheel is connected on the edge of track (21) both sides Ji, ensures that underslung trolley does not drop, so as to ensure that crane is safe to use；It is outstanding Hang dolly side two sets of drive mechanisms of installation to be connected on same track, and roller devices are installed beside every set drive mechanism (35), its be advantageous in that can avoid single driving be possible to because dolly somewhat upwarp on one side adhesion wheel not rail and caused by run not Dynamic phenomenon, dual drive ensure that trolley travelling is smooth；Roller devices can limit underslung trolley while the degree upwarped, ensures that suspension is small Car is stable, and operation is smooth；Power supply needed for underslung trolley and electric block and rotating mechanism is by lashed cable (123) along choosing electric frame Upper cable wire rail (124) can run power supply back and forth with underslung trolley；Cable wire rail both ends are connected to two and choose electric frame (121), The appropriate height of electric frame is chosen by adjustment, lashed cable can be solved and most preferably hang position；Cable wire rail is to make track, cost using steel wire rope It is low.

Car bumper (70) on the application middle girder track, the operation stroke of underslung trolley can be limited, ensure safety.

The electric block cable (200) of the application crane is from the suspension rod axis center in rotating mechanism by being connected to collection Electric slip ring (9), cable (200), which will not be wound, not to be torn, is not required to set rotary limit device, ensures that cantilever beam can be in level Arbitrary Rotation on face；There is the gear auxiliary driving of a pair of elevating arc transmissions in rotating mechanism, pass through big elevating arc, small elevating arc The different numbers of teeth setting, precise requirements of the user to the cantilever beam rotary speed of crane can be met, avoid direct selection standard Reductor it is general speed than and caused cantilever beam rotating speed and the larger error of actual demand；It is driven using elevating arc, rotation can be made Drive device in rotation mechanism uses horizontal speed-reducer, reduces 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.

Cantilever beam in the application, which is provided at both ends with buffing pad, can avoid electric block from moving back and forth impact along cantilever beam Or overtravel；After stop nut in cantilever member connection connects with suspension rod axle thread, then to have locking plate (110) to be connected to locking Nut is with suspension rod axle spindle-end looseness-proof breach, avoiding stop nut from unclamping, securely and reliably；Blind hole on stop nut can facilitate thick stick Bar inserts, and it is light to pull nut, easy disassembly and maintenance.
