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 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 arranged 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 now the wheel rim of horizontal wheels is caught on Running track, avoid crane from tumbling, ensure 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, it is such to combine the supporting multigroup wheel of end carriage, the wheel group of small-wheel-diameter can be used, makes the sectional dimension of end carriage small, is 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 practical；The wheel body of connecting shaft wheel is once swaged into wheel shaft, simple in construction, especially suitable path wheel, in connecting shaft wheel As long as the heart meets and power set input axis connection, one section of axis hole of processing, reduction processing capacity；In inner flange seat and blank cap type It is that can stand very big axial float flange seat all without departing from position that the ring flange of flange seat, which is connected to benefit on the inside of end carriage, Connecting bolt is not needed to bear big axial tension；Blank cap type inner flange seat one end in the application is arranged to the boring cover of closing Formula, can be with dust seal；Reducing motor in the application is connected in fixed seat by cushion pad, due to fixed seat rigid solder , it is necessary to which the cushioning effect of cushion pad produces impact shock to mitigate reducing motor startup, brake on end carriage lateral wall, protect Drive device；The drive device of the application, it is simple in construction without shaft coupling, from heavy and light, it is convenient to mount and dismount, good concentricity, noise It is small, operate steadily.

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 It can be moved back and forth along girder both ends, be suitable for big width workshop and use；Hang end carriage dolly and electric block and whirler Power supply needed for structure can run power supply back and forth by the lashed cable (123) on dolly lashed cable device (124) with suspension end carriage dolly.

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.

Rotating mechanism in the application is provided with rotary limit device, by safety ruler (583) and two travel switches (581) Composition, safety ruler are arranged on suspension rod axle upper end, and travel switch is arranged on trolley frame upper surface, are more convenient installation and adjustment；Safety ruler (583) when swing rod one end is advantageous in that spline tooth connection corresponding with suspension rod axle provided with splined hole (5833), the angle of safety ruler Degree direction is adjusted well, and suspension rod axle can be inserted in the direction arbitrarily needed and is fixed, keeps most suitable position；There is rotation Stopping means, cantilever beam can be avoided excessively to rotate, prevent the cable (100) of electric block to be wrapped in the Holder for hanging household utensiles in cantilever member (52) be torn on because the cable (100) of electric block be draw from the junction box on trolley frame it is 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 lifting power by thrust bearing, and suspension rod axle is by bearing The spacing firmly radial positions of A and above and below bearing B, ensure that suspension rod axle can bear very big axial force and not offset radially, so as to ensure Drive device axiality is good, and hinged cantilever component is laborsaving；After stop nut in cantilever member connection connects with suspension rod axle thread, The diameter for having bolt (99) through stop nut and suspension rod axle again connects, and avoids stop nut from unclamping, securely and reliably.
