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.

Horizontal wheel apparatus in the application crane is installed on the both ends of every end carriage, it is ensured that crane operation is not gnawed Rail, is especially suitable for large span crane；Horizontal wheels in horizontal wheel apparatus carry wheel rim, can serve " safety hook ", may Because of cantilever beam load exceedance, for crane end carriage while upwarping, the wheel rim of horizontal wheels catches on running track at this time, avoids crane from inclining Turn over, ensure safety；It can be rotated in the same old way while horizontal wheels catch on track, crane can run advance in the same old way, and this technology makes With more advanced than the safety hook of steel plate type, 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 highly practical；The wheel body of connecting shaft wheel is once swaged into wheel shaft, simple in structure, 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, Bolt need not be connected and 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；Decelerating 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 is to mitigate decelerating motor startup, braking produces impact vibration on end carriage lateral wall, protect Driving device；The driving device of the application, it is simple in structure without shaft coupling, from heavy and light, it is convenient to mount and dismount, good concentricity, noise It is small, operate steadily.

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 needed for underslung trolley and electric block and rotating mechanism can be with underslung trolley by lashed cable Operation power supply back and forth；Gantry top has a plurality of electric frame (121) of choosing to lead the connection of cable rail, keeps leading the rigidity of cable rail, it is ensured that lashed cable Coaster slides smooth in cable rail is led.

Car bumper device (70) on the application middle girder track is flexibly connected in orbit, and welding is solid when not being processing and manufacturing It is fixed, but during in-site installation, fixed according to field condition bolt；Its benefit allows underslung trolley to be run on crane runway The link position for the stroke selection car bumper device that position allows according to workshop condition, Field adjustment position is welded without gas cutting, is protected Card underslung trolley is rightly blocked by car stop upper bumper, reduces impact, increase trolley travelling safety；The connection position of car bumper Put flexibly, position is adjustable, and environmental suitability is stronger；Two fixed seats (701) left and right in car bumper device can be general, fixed seat It is welded by steel plate or is made by rectangular steel tube, selection is simple, easy to make.

Bearing block and sunpender axis connection in the application rotating mechanism bear lifting power by thrust bearing, and sunpender axis is by bearing The spacing firmly radial positions of A and above and below bearing B, ensure that sunpender axis can bear very big axial force and not deviate radially, so as to ensure Driving device concentricity is good, and hinged cantilever component is laborsaving；Driving device output shaft in rotating mechanism by shaft coupling (48) with Sunpender axis connection, increases degree of flexibility, improves the malalignment regulating power between driving device and sunpender axis；Cantilever member connects In stop nut connected with sunpender axle thread after, then there is bolt (99) to be connected through stop nut with the diameter of sunpender axis Come, avoid stop nut from unclamping, securely and reliably.

In the application cantilever beam be provided at both ends with buffing pad can avoid electric block along cantilever beam move back and forth impact or Overtravel；Rotary limit device (58) is equipped between cantilever member and underslung trolley, cantilever beam can be avoided excessively to rotate, i.e., do not surpassed The rotation of 360 degree of angles is crossed, prevents from being pulled on Holder for hanging household utensiles (52) that the cable (100) of electric block is wrapped in cantilever member It is disconnected because the cable (100) of electric block be draw from the junction box on trolley frame it is ensuing；Rational installation is safety ruler weldering It is connected on cantilever member, travel switch is fixed on below trolley frame.
