Having the beneficial effects that of the application is as described below:

Cantilever beam in the application crane can stretch out between crane locomotive to outdoors or directly lifting goods to workshop, next door Thing；Not only can lift by crane workshop, the next door goods of cart traffic direction end points, and cart can be lifted by crane and run railway line side The goods in workshop；Owing to the cantilever beam of the application is arranged at below dolly and girder, cantilever beam can stretch into by below support rail beam The direct lifting cargo in workshop, next door, or can directly stretch out the workshop operation outdoors of cart traffic direction, therefore present techniques is special Levy and can realize the application purpose；After lifting goods, by electric block moving along cantilever beam, or by cantilever member Rotate, or by the movement of running trolley, or by the motion of crane, or by aforementioned four integrated motions, permissible The goods of lifting is hung onto the place that this workshop needs；Goods friendship is carried out outdoors in the workshop, next door or workshop with workshop surrounding The transhipment of other transporting equipment can be used when connecing, improve efficiency.

The cantilever crane of the application is suitable on the metope column the most on one side of workshop setting up bracket to lay track, another side Use the environment of workshop track；On end carriage in crane semi portal, cart running gear runs on column track, sill On cart running gear run in the track of workshop；Cart running gear includes cart actuating device, is formed by motor car wheel etc..

End carriage in the application crane use two balances end carriage (102) and a middle connecting rod (101) connection and Become；Sill is formed by connecting by two balances grade beam (302) and a middle tie-beam (301)；Such combination beam is supporting many Group wheel, can use the wheel group of small-wheel-diameter, and the sectional dimension making combination beam is little, and constructions cost is low, and it is big to solve crane Tonnage little wheel load problem.

Running trolley (3) in the application is above girder, and can move back and forth along girder two ends, be suitable for greatly across Degree workshop uses；Running trolley both sides arrange safety hook (33) and cantilever beam overload can be avoided to produce running trolley and upwarp, it is ensured that Running trolley catches on girder siding track and does not drops, thus ensures that crane uses safety；Running trolley arranges two set dollies and drives Device (32), can avoid singly driving likely somewhat upwarp because of dolly adhesion wheel not rail and produce can't run phenomenon, protect Card trolley travelling is smooth and easy；Two adhesion wheel groups in the application drive car pass through spline box coupling (325) Couple together with floating axle, spline housing simple in construction, the little handling ease of size, from heavy and light low cost, wherein use floating axle and Spline housing coordinates makes the not parallel error compensation of axis good.

The safety hook (33) installed on running trolley in the application, by T-shaped hook seat and L-shaped hook body be bolted and Become, the convenient regulation of this spline structure；T-shaped hooks the horizontal elongated hole (3312) on seat and the vertical direction elongated hole (3322) with L-shaped hook Mutually regulation, makes can the most front and back adjust between eave tile and siding track gap；Hold with the siding track on girder during in-site installation Easily adjust most suitable gap to connect, it is allowed to bigger manufacture mismachining tolerance, scene can be installed.

End carriage and sill two ends in the application crane all arrange cart actuating device, it is ensured that cart runs smooth and easy, May upwarp because of end carriage when avoiding monolateral driving, drivewheel not rail produce idle running phenomenon；The cart actuating device (8) of the application Be standard component by motor car wheel group, its simple in construction, lightweight, can whole set procurement, buying is convenient, and price is low.

Horizontal wheels device (6) in the application crane is arranged on the two ends of end carriage, horizontal wheels wheel on end carriage is limited Make and run in orbit centre, it is ensured that crane runs and do not gnaws rail；Horizontal wheels in horizontal wheels device is with wheel rim, Ke Yiqi " safety hook " acts on, and may upwarp because of cantilever beam load exceedance, crane end carriage, and now the wheel rim of horizontal wheels catches on operation Track, it is to avoid crane is tumbled, it is ensured that safety；Horizontal wheels can rotate while catching on track in the same old way, and crane is the most permissible Running and advance, this technology uses more advanced than the safety hook of steel plate type, and cart runs and stuck phenomenon does not occur；Due to sill length Longer than end carriage, so arranging horizontal wheels device on end carriage i.e. can reach anti-effect of tumbling.

One end end in cantilever beam (51) in the application cantilever member is fixing connects buffer, plays buffer capacity spacing electronic Calabash effect；Cantilever end at cantilever beam connects the adjustable car bumper device in a position (70), and its effect is the buffering on car stop Electric block can be avoided to move back and forth impact along cantilever beam for device or overtravel is run, and the position of this car bumper device is the most adjustable, Its benefit is according to the goods size cases lifted, can flexible car bumper device fixed position, its essence is regulation cantilever The effective breadth of beam, little tonnage amplitude can be big, and large-tonnage is with by a small margin；Effectively utilize crane, ensure safety simultaneously.

Bearing block and the connection of suspension rod axle in the application rotating mechanism are born gravity by thrust bearing, and thrust bearing is arranged on Bearing block top, it is simple to dismounting；The inner hole structure of bearing block is simply easy to processing；Sleeve (43) is that sliding bearing made by high-abrasive material Using, reduce the fit clearance of suspension rod axle, increase rotational stabilization, increase the axiality of drive mechanism, cantilever member rotates and saves Power；Stop nut A band dust cover (441) gives bearing proofing dust and protecting, can seal the butter in bearing simultaneously；Stop nut A with hang After bar axle connects, then by the connection of bolt (46), play locking effect, it is ensured that rotating mechanism safety；Driving in rotating mechanism Dynamic device output shaft is connected with suspension rod axle by shaft coupling (48), increases degree of flexibility, improves between driving means and suspension rod axle Malalignment regulating power.

It is provided with rotary limit device (58) between cantilever member and trolley frame in the application, cantilever beam can be avoided excessively to revolve Turn, i.e. rotate less than 360 degree of angles, prevent the Holder for hanging household utensiles (52) that the cable (200) of electric block is wrapped in cantilever member Upper and be torn because the cable of electric block (200) to be that the junction box from Liang Taishang draws ensuing；Cantilever member and suspension rod After axle connects, connect location by stop nut and suspension rod male thread, safe and reliable.
