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 of underslung trolley (3) can be stretched out between crane locomotive to outdoors or to next door workshop in the application crane Directly lift cargo；The next door workshop cargo of cart traffic direction endpoint can be not only lifted by crane, and cart operation can be lifted by crane The cargo in railway line side workshop；Since the cantilever beam of the application is arranged at below trolley and girder, cantilever beam can pass through support rail The direct lifting cargo in next door workshop is stretched into below beam, or can directly stretch out the workshop operation outdoors of cart traffic direction, because logical The door top in normal workshop can reach height where the support rail beam in this workshop substantially, therefore present techniques feature can realize the application Purpose；After lifting cargo, by movement of the electric block along cantilever beam, or the rotation by cantilever member, or pass through suspension The movement of trolley, or the movement by crane travelling mechanism, or by foregoing four integrated motion, can be lifting Cargo hangs onto the place of this workshop needs；Can not when carrying out cargo handing-over outdoors with the next door workshop of workshop surrounding or workshop The transhipment of other transporting equipments must be borrowed, improves efficiency.

Trolley track (21) is set below the girder in the application crane, and underslung trolley is suspended on girder track, makes Its installation space position reduces, and is particularly suitable for roofing with crane apart from small workshop.

The suspension hook on lifting truck (01) in the application crane and electric block (10) suspension hook on underslung 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 underslung trolley (3) power supply.

Anti- tipple in the application crane is installed on the both ends of every end carriage, and wheel on end carriage is limited by horizontal wheels System is run in orbit centre, it is ensured that rail is not gnawed in crane operation, is especially suitable for large span crane；This anti-tipple One of advantage horizontal wheels are installed in engineer room (631), and wheel shaft (62) both ends are all fixed in the through hole (632) of engineer room, such water Cantilever, wheel shaft can not bear big lateral impact forces not flexural deformation to flat wheel；Horizontal wheels in anti-tipple carry wheel rim, can , may be because of cantilever beam load exceedance to play " safety hook ", crane end carriage is while upwarp, and the wheel rim of horizontal wheels is caught at this time Running track, avoids crane from tumbling, and ensures safety；It can be rotated in the same old way while horizontal wheels catch on track, crane is in the same old way Advance can be run, using more advanced than the safety hook of steel plate type, stuck phenomenon does not occur this technology for cart operation.

End carriage in the application crane connected using two balance beams (102) and a middle connecting rod (101) and Into such combination supporting multigroup wheel of end carriage, can use the wheel group of small-wheel-diameter, make the sectional dimension of end carriage small, be configured to This is low, and can solve the problems, such as the small wheel load of crane large-tonnage.

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 highly practical；The wheel body of connecting shaft wheel is once swaged into wheel shaft, simple in structure, 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 connection bolt of seat need not bear big axial tension, and wheel alignment is good；The output shaft of decelerating motor can be flat key axis or Splined shaft or double bond axis, according to torque different situations, rationally coordinate with wheel axis hole；Decelerating motor is connected by cushion pad On end carriage, due to the cushioning effect of cushion pad, alleviate decelerating motor and start, brake generation impact vibration, protect driving Device.

Passive wheel group on the application end carriage uses connecting shaft wheel, and wheel body is once swaged into wheel shaft, reduces axial gear Many accessories such as circle, it is simple in structure, it is especially suitable for path wheel.

Underslung trolley (3) in the application can be moved back and forth along girder both ends, be suitable for big width workshop and used；Suspension Driving mechanism (34) on trolley can be in whole set procurement standarized component on the market, supporting facility；Driving wheel, quilt in driving 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 trolley side two sets of driving mechanisms of installation to be connected on same track, and roller devices are installed beside every set driving mechanism (35), its be advantageous in that can avoid single driving be possible to because trolley somewhat upwarp on one side adhesion wheel not the race that produces rail not Dynamic phenomenon, double drive ensure that trolley travelling is smooth；Roller devices can limit underslung trolley while the degree upwarped, ensures that suspension is small Car is stablized, and operation is smooth；Power supply passes through on trolley lashed cable device (124) needed for underslung trolley and electric block and rotating mechanism Lashed cable (123) power supply can be run back and forth with underslung trolley.

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

The electric block cable (200) of the application crane is from the sunpender 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 a pair of of elevating arc auxiliary driving in the rotating mechanism of the application, pass through big elevating arc, small elevating arc Different number of teeth settings, can meet precise requirements of the user to the cantilever beam rotary speed of crane, avoid selection standard gear reducer It is general speed ratio and produce cantilever beam rotating speed and actual demand large error；It is driven using elevating arc, rotating mechanism can be made In driving device use horizontal speed-reducer, it is easy for installation, can be directly installed on trolley frame, and it is high to reduce installation Degree.

Bearing block and sunpender axis connection in the application rotary mechanism of crane bear lifting power, sunpender axis by thrust bearing By the spacing firmly radial position of bearing A and above and below bearing B, ensure that sunpender axis can bear very big axial force and not deviate radially, from And ensureing that driving device concentricity is good, hinged cantilever component is laborsaving；Cantilever beam, which is provided at both ends with buffing pad, can avoid electric block Impact or overtravel are moved back and forth along cantilever beam；After stop nut in cantilever member connection is connected with sunpender axle thread, then There is locking plate (110) to be connected to stop nut with sunpender axis spindle-end looseness-proof notch, avoiding stop nut from unclamping, securely and reliably.
