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.

Horizontal wheels device in the application crane is arranged on two of end carriage, it is ensured that crane runs and do not gnaws rail, the suitableeest Close large span crane；Horizontal wheels in horizontal wheels device, with wheel rim, can play " safety hook " effect, may be because of cantilever beam Load exceedance, crane end carriage upwarps, 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 can run advance in the same old way, and this technology uses and compares steel plate The safety hook of formula is advanced, 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) simple in construction of the application, mounting or dismounting Convenient, car wheel structure is the most easy to process；Independent axletree connects, and can be set to different length and different size of axle is stretched, Can actuating unit with outside multi-form be connected easily；The axle of the application axletree stretches the insertion three-in-one reductor of hollow type (electricity Machine, reductor, brake three combine) be attached thereto, whole drive mechanism small in volume；The ring flange of inner flange seat is even The benefit being connected on end carriage side inner walls is to stand the biggest axial float inner flange seat all without departing from position, it is not necessary to connect Bolt bears big axial tension, and wheel alignment is good；The output shaft of the three-in-one reductor of hollow type and motor shaft can be parallel or Horizontal direction is vertical or vertical direction vertical, according to space situation, selects different installation forms, with applicable normal safe Run；The driving means of the application, of many uses, without shaft coupling, simple in construction, from heavy and light, it is convenient to mount and dismount, concentricity Good, noise is little, operates steadily.

Easy by motor car wheel group compact conformation, mounting or dismounting on the application end carriage；Car wheel structure is the most easy to process, by separate bearings Lid and the axle sleeve location to wheel, process these accessory low costs；The center of wheel can be adjusted by adjusting the different-thickness of axle sleeve Position, adjusts and gnaws rail problem；It is to stand in the biggest axial float that the ring flange of inner flange seat is connected to benefit inside end carriage Flange seat is all without departing from position, it is not necessary to attachment screw bears big axial tension.

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 beam two ends in the application are provided with buffing pad and electric block can be avoided to move back and forth impact along cantilever beam or be out of the line Journey；Cantilever member connect in stop nut and suspension rod male thread connect after, then have locking plate (110) be connected to stop nut with In suspension rod axle spindle-end looseness-proof breach, it is to avoid stop nut unclamps, safe and reliable.
