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

Owing to the cantilever beam of the application is arranged at below girder, cantilever beam can directly stretch out the workshop of cart traffic direction to be carried out outdoors Operation, because the door top in usual workshop can reach the support rail beam place height in this workshop substantially, therefore present techniques feature is permissible Reach the application purpose；After lifting goods, by electric block moving along cantilever beam, or by the rotation of cantilever member, Or by the motion of crane driving means, or by aforementioned three's integrated motion, the goods of lifting can be hung onto this The place that workshop needs, Liang Tai (3) is fixed on girder motionless, and this crane is suitable for narrow workshop；With workshop, next door Or workshop carries out can using during goods handing-over the transhipment of other crane gear outdoors, improve efficiency.

Anti-tipple in the application crane is arranged on the two ends of every end carriage, horizontal wheels wheel on end carriage is limited in rail Center, road is run, it is ensured that crane runs and do not gnaws rail, is especially suitable for large span crane；The advantage of this anti-tipple it One horizontal wheels is arranged in engineer room (631), and wheel shaft (62) two ends are all fixed in the through hole (632) of engineer room, such level Taking turns not cantilever, wheel shaft can bear big lateral impact forces not flexural deformation；Horizontal wheels in anti-tipple is with wheel rim, permissible Playing " safety hook " effect, may upwarp because of cantilever beam load exceedance, crane end carriage, now the wheel rim of horizontal wheels catches on Run 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 in the same old way Can run advance, this technology uses more advanced than the safety hook of steel plate type, and cart runs and stuck phenomenon does not occur.

End carriage in the application crane uses two balances end carriage (102) and a middle connecting rod (101) to be formed by connecting, this The combination end carriage of sample is supporting organizes wheel more, can use the wheel group of small-wheel-diameter, and the sectional dimension making end carriage is little, and constructions cost is low, And crane large-tonnage little wheel load problem can be solved.

End carriage two ends in the application crane all arrange cart actuating device, it is ensured that cart runs smooth and easy, it is to avoid during monolateral driving Because end carriage may upwarp, drivewheel not rail produce idle running phenomenon；Cart actuating device (8) novel structure of the application is practical Property is strong；The wheel body of connecting shaft wheel is once swaged into wheel shaft, simple in construction, is especially suitable for path wheel, the ring flange of inner flange seat Being connected to benefit inside end carriage is to stand the biggest axial float inner flange seat all without departing from position, the connection of inner flange seat Bolt 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 Key axle, according to torque different situations, with wheel axis hole reasonable coordination；Reducing motor is connected on end carriage by cushion pad, Due to the cushioning effect of cushion pad, alleviate reducing motor and start, brake generation impact shock, protect driving means.

Being used connecting shaft wheel by motor car wheel group on the application end carriage, wheel body is once swaged into wheel shaft, decreases axial back-up ring etc. very Multiple accessory, simple in construction, it is especially suitable for path wheel.

Cantilever beam (51) in the application cantilever member, at Holder for hanging household utensiles (52) that end fixing connection buffer, plays buffer capacity spacing Electric block effect；Cantilever end at cantilever beam connects the adjustable car bumper device in a position (70), and its effect is delaying on car stop Rushing device can avoid electric block to move back and forth impact or overtravel operation along cantilever beam, 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 beam Effective breadth, little tonnage amplitude can be big, and large-tonnage is with by a small margin；Effectively utilize crane, ensure safety simultaneously.

The electric block cable (200) of the application crane suspension rod axle from rotating mechanism is centrally through being connected to bus ring (9), cable (200) will not be wound around and not be torn, and is not required to arrange rotary limit device, it is ensured that cantilever beam can be in the horizontal plane Arbitrary Rotation；Rotating mechanism has the gear pair transmission of a pair elevating arc transmission, by big elevating arc, little elevating arc not Set with the number of teeth, user's precise requirements to the cantilever beam rotary speed of crane can be met, it is to avoid directly selection standard reductor General speed ratio and the bigger error of the cantilever beam rotating speed that produces and actual demand；Use elevating arc transmission, can make in rotating mechanism Driving means use Horizontal speed-reducer, reduce setting height(from bottom).

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 use made by high-abrasive material, Reducing the fit clearance of suspension rod axle, increase rotational stabilization, increase the axiality of drive mechanism, cantilever member rotates laborsaving；Anti- Pine nut A band dust cover (441) gives bearing proofing dust and protecting, can seal the butter in bearing simultaneously；Stop nut A is with suspension rod axle even After connecing, then by the connection of bolt (46), play locking effect, it is ensured that rotating mechanism safety.

The motor of the driving means (40) in the application rotating mechanism is from brake device, it is to avoid after parking, inertia rotates, thus Realize cantilever beam brake i.e. to stop, it is ensured that on cantilever beam, electric hoist suspension hook point position is accurate.

Cantilever member in the application connect in stop nut and after suspension rod male thread connects, then have locking plate (110) to be connected to In stop nut and suspension rod axle spindle-end looseness-proof breach, it is to avoid stop nut unclamps, safe and reliable.
