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.

End carriage both sides in the application crane all set anti-tipple (11), crane can be avoided to tumble, and ensure peace Entirely；When cantilever beam may overload, end carriage is while upwarp, and now the eave tile of L-shaped safety hook can catch on cart support rail beam (12) Upper cover plate Ji edge, avoid crane from tumbling and ensure safety；Anti- tipple is connected with end carriage, and in-site installation is constructed just Profit, assembled in situ are not required to be welded, and avoid damage to equipment surface paint；T-shaped on anti-tipple hooks seat (111) and L-shaped safety Hook (112) to be designed with connecting elongated hole, in crane in-site installation, be easy to adjust relative position, easily installation is in place；Work as lifting When generator terminal beam upwarps, by hinged cantilever component or mobile electric cucurbit position or lift heavy can be reduced, can so changed Become the center of gravity of crane, ensure that stabilization avoids crane from tumbling.

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；The splined sleeve (811) of inside wheel loads inside wheel after individually processing, and can dismantle；Spline housing The small good processing of cylinder size, can make, long lifespan replacement cost is low of special high-abrasive material；The bearing of wheel is solid by logical lid connection It is fixed more firm；Hollow flange axle is hollow, and drive shaft passes therethrough；Ring flange (851) on hollow flange axle had both been used for End carriage is connected, is used to connect reducing motor again, positions reducing motor；The output shaft of reducing motor passes through hollow flange shaft hollow hole It is connected with the splined sleeve of inside wheel and directly drives wheel；Positioning flange collar on reducing motor, which is inlayed, is connected to hollow flange In the motor positioning hole (853) of axle, the connecting hole on reducing motor flange seat leads to the motor connection screw on hollow flange axle Bolt is crossed to be 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 Connect not only simple but also firmly between motor and wheel, axiality is good, takes up space small, ensures that wheel steadily operates, operating is vibrated It is small, 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 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.

Trolley driving mechanism wheel is arranged on inside suspension end carriage in the application, and suspension end carriage is connected with the track under girder When whole height it is small, so entirely suspension end carriage dolly swings small, stablizes；The anti-roller devices set on trolley frame can limit The end carriage dolly degree upwarped on one side is hung, the roller in anti-roller devices can be pressed in below track (21), counter suspended end Beam dolly upwarps, smooth so as to keep trolley travelling to stablize.

Elongated hole is provided with bearing side panel in anti-roller devices in the horizontal direction to install with roller shaft, its benefit is easy for Roller dismounting maintenance；When the bearing damage in roller devices, roller and its roller shaft can be taken off repairing from bearing horizontal direction, It is easy to operate.

Cantilever beam in the application cantilever member, which is provided with, leads cable rail and lashed cable (6)；Described lashed cable one end connects electronic calabash Lu Youguan control systems, the other end are connected on the bus ring (9) from the centre bore of suspension rod axle after, and lashed cable (6) can As suspension rod axle rotates；The hanging wire will not be wrapped on cantilever member, be not torn, and be not required to set rotation limit on cantilever member Position device, ensure that cantilever beam can Arbitrary Rotation in the horizontal plane；There is a pair of elevating arcs are secondary to pass in the rotating mechanism of the application It is dynamic, set by the different numbers of teeth of big elevating arc, small elevating arc, standard of the user to the cantilever beam rotary speed of crane can be met Really require, avoid selection standard reductor it is general speed than and caused cantilever beam rotating speed and the larger error of actual demand；Make It is driven with elevating arc, the drive device in rotating mechanism can be made to use horizontal speed-reducer, it is easy for installation, it can be directly installed on small On vehicle frame, and setting height(from bottom) can be reduced.

The motor of drive device (40) in the application rotating mechanism is from brake device, and inertia rotates after avoiding parking, So as to realize that cantilever beam brake stops, ensure that electric hoist suspension hook point position is accurate on cantilever beam.

Bearing block and suspension rod axis connection in the application rotary mechanism of crane bear lifting power, suspension rod axle by thrust bearing By the spacing firmly radial position of bearing A and above and below bearing B, ensure that suspension rod axle can bear very big axial force and not offset radially, from And ensureing that drive device axiality is good, hinged cantilever component is laborsaving；Stop nut and suspension rod axle thread in cantilever member connection After connection, then there is locking plate (110) to be connected to stop nut with suspension rod axle spindle-end looseness-proof breach, avoiding stop nut from unclamping, Securely and reliably.
