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；Not only The next door workshop goods of cart traffic direction end points can be lifted by crane, and the goods in cart running track line side workshop can be lifted by crane； Because the cantilever beam of the application is arranged at below dolly and girder, cantilever beam can directly be risen by stretching into next door workshop below support rail beam Hoisting thing, or the workshop operation outdoors of cart traffic direction can be directly stretched out, therefore present techniques feature can realize the application Purpose；After lifting goods, by motion of the electric block along cantilever beam, or the rotation by cantilever member, or pass through operation The movement of dolly, or the motion by crane, or by foregoing four integrated motion, the goods of lifting can be hung The place needed to this workshop；It need not can be borrowed when carrying out goods handing-over outdoors with the next door workshop of workshop surrounding or workshop other The transhipment of transporting equipment, improve efficiency.

The cantilever crane of the application be suitable for workshop only have set up on the metope column of one side bracket laying track, another side uses car Between track environment；Cart actuating device is run on column track on end carriage in crane semi portal, and the cart on grade beam drives Dynamic device is run in the track of workshop；Cantilever beam can reach next door workshop among supporting rack and be lifted or unloaded goods.

Running trolley (3) in the application can move back and forth in the top of girder along girder both ends, be suitable for large span car Between use；Running trolley both sides set safety hook (33) that cantilever beam can be avoided to overload and produce running trolley and upwarp, and ensure operation Dolly catches on girder siding track and not dropped, so as to ensure that crane is safe to use；Running trolley sets two sets of drive cars (32), can avoid single driving be possible to because dolly somewhat upwarp adhesion wheel not rail and caused by can't run phenomenon, ensure dolly Run smooth；Two adhesion wheel groups in the application drive car pass through spline box coupling (325) and floating axle Connect, spline housing is simple in construction, the small handling ease of size, low from heavy and light cost, wherein being matched somebody with somebody using floating axle and spline housing Conjunction makes the not parallel error compensation of axis good.

The safety hook (33) installed on running trolley in the application, seat is hooked by T-shaped and L-shaped hook body is bolted and formed, This spline structure is convenient to be adjusted；T-shaped hooks the vertical direction elongated hole (3322) with horizontal elongated hole (3312) and L-shaped hook on seat Mutually regulation, make that front and rear up and down gap can be adjusted between eave tile and siding track；It is easy with the siding track on girder during in-site installation Adjust most suitable gap connection, it is allowed to which larger manufacture mismachining tolerance, scene can install.

Anti- tipple in the application crane is arranged on the both ends of end carriage, and wheel on end carriage is limited in track by horizontal wheels The heart is run, it is ensured that rail is not gnawed in crane operation；One of the advantages of this anti-tipple horizontal wheels are arranged in engineer room (631), Wheel shaft (62) both ends are all fixed in the through hole (632) of engineer room, and cantilever, wheel shaft can not bear big horizontal punching to such horizontal wheels Hit power not flexural deformation；Horizontal wheels in anti-tipple carry wheel rim, can play " safety hook ", may be because of cantilever beam Load exceedance, for crane end carriage while upwarping, now the wheel rim of horizontal wheels catches on 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 can run advance in the same old way, and this technology use is than steel plate The safety hook of formula is advanced, and stuck phenomenon does not occur for cart operation；Because ground beam length is longer than end carriage, so being set on end carriage anti- Tipple.

End carriage and grade beam both ends in the application crane all set cart actuating device, ensure that cart operation is smooth, avoid unilateral Because end carriage or grade beam may upwarp during driving, driving wheel not rail produce idle running phenomenon；Cart actuating device (8) knot of the application Structure is novel, practical；The wheel body of connecting shaft wheel is once swaged into wheel shaft, simple in construction, is especially suitable for path wheel, interior method It is that can stand very big axial float inner flange seat all without departing from position that the ring flange of blue seat, which is connected to benefit on the inside of end carriage, interior The connecting bolt of flange 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 It is connected on end carriage or grade beam, due to the cushioning effect of cushion pad, alleviates reducing motor and start, brake generation impact shock, protect Drive device is protected.

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, The fit clearance of suspension rod axle is reduced, increases rotational stabilization, increases the axiality of drive mechanism, cantilever member rotates laborsaving；It is anti- Loose nut A band dust covers (441) give bearing proofing dust and protecting, while can seal the butter in bearing；Stop nut A connects with suspension rod axle After connecing, then the connection by bolt (46), anti-loose effect is played, ensures rotating mechanism safety；Driving dress in rotating mechanism Output shaft is put by shaft coupling (48) and suspension rod axis connection, increases degree of flexibility, improves the difference between drive device and suspension rod axle Axle degree regulating power.

Rotary limit device (58) is provided between cantilever member and running trolley in the application, cantilever beam can be avoided excessively to rotate, Be no more than the rotations of 360 degree angles, prevent the cable (200) of electric block be wrapped on the Holder for hanging household utensiles in cantilever member (52) and Be torn because the cable (200) of electric block be draw from the junction box on running trolley it is ensuing；Cantilever member and suspension rod After axis connection, after positioning is connected with suspension rod axle thread by stop nut, then with bolt (99) stop nut and suspension rod axle are passed through Diameter connect, avoid stop nut from loosening, securely and reliably.
