Description

It is a kind of to drive crane with the dolly steel cable of C-shaped channel cantilever beam and safety hook

Technical field

The application is related to crane field, more particularly to a kind of with the drive of the dolly steel cable of C-shaped channel cantilever beam and safety hook Dynamic crane.

Background technology

Existing bridge crane is applied in Workshop, and the product and raw material in workshop are required for Real-Time Transport to next door Workshop or other departments；The suspension hook of crane on workshop is hung from dolly carries out lifting goods, and dolly can only be along Crane twin beams is run back and forth, and crane can only be run back and forth along the cart track on the end bay post of workshop two, such crane The goods scope that suspension hook can lift is in this plane within the plane that the two-end-point of the two cart tracks in workshop is surrounded When the goods at edge needs lifting, suspension hook just produces oblique pull, then from far point outside this plane article (such as workshop outdoors, across It cannot lift, can only now be transported by other transporting equipments outside), workshop is generally driven under suspension hook by automobile and hung Loading thing, some cars are opened laterally lays track without coming between this workshop and next door workshop, allows trolley special to reach and hangs Hook gets off to join goods, and some sets up a special cantilever crane in workshop doorway (or workshop passageway), to the goods outside workshop It is transported through scheduling, first goods is lifted up into the place that this workshop crane suspension hook is got at, then again by crane this Goods handling is to the other stations in workshop, and the existing bridge crane that is used under this operating mode can not directly join with next door workshop Goods, must be by other transporting equipment schedule jobs, and it is quite inconvenient to bring, and also produces manpower and materials and wastes；Some grains having Crane requirement used in warehouse and the explosion-proof workshop article hoisting of industry electrically has explosion prevention function, it is necessary to fire-proof motor, explosion-proof Electric block cost is very high, and particularly tonnage is little, using the not high place of working level, uses anti-explosion electric lifting speculative investment Greatly, maintenance cost is high；Workshop also does not provide electric power, carries out Articles transfer by fork truck or manpower, labor intensity is excessive.

The content of the invention

The beneficial effect of the application is：

The crane of the application can under no electric power environmental or mustn't use electrical equipment explosion-proof environment under use, It is novel reliable；Because the cantilever beam of the application is arranged at below girder, cantilever beam can be directly stretched out between crane locomotive to outdoors Or directly lift goods to next door workshop；The lifting or decentralization goods for pulling ring-chain hoist (200) rely on and pull chain (201) Pulling function is operated；By drawing, dragging or slant handle zip strip (201) or pull steel cable on ring-chain hoist suspension hook, make cunning Car (6) is along cantilever beam transverse movement；Pass through pulling chain (201) and cantilever beam can be rotated in oblique pull hand draw ring chain block And can random angle rotation；By pulling the chain (84) pulled in cart running gear to drive whole crane along workshop rail Run back and forth in road；It can be run by above-mentioned integrated motion, such as cart, cantilever beam rotates, coaster motion, ring-chain hoist suspension hook liter Drop, running trolley motion, just can object by pull driving from outdoors or the handling of next door workshop to workshop domestic demand will place, Carry out to borrow the transhipment of other transporting equipments outdoors with the next door workshop of workshop surrounding or workshop during goods handing-over, it is convenient Operation；Coaster is the conventional accessory for hanging Transport Machinery industry, easily buying.

In the case where manually pulling chain (710) effect, running trolley can be run running trolley along girder both ends in the application, It is adapted to large span workshop operation.

Running trolley is low using wire rope traction driving cost in the application, easy to maintenance；Two bar steels of running under power dolly Rope is respectively with two reel elevators, it is not necessary to strainer；Reel A (73) and reel B (76) are connected to power transmission shaft by ratchet On, its pleasant place is to realize that reel A and reel B are synchronous with the one-directional rotation of power transmission shaft, another to free to rotate；Work as steel cable Pull dolly, during reel serving, artificial pulling force passes to power transmission shaft, and power transmission shaft drives reel serving, and the reel of serving is necessary And then power transmission shaft synchronous axial system；And loosen the reel of steel cable over there can be asynchronous with power transmission shaft, be passively to put rope；Because serving Drum diameter it is increasing, put that the drum diameter of rope is less and less, rope closing is identical with the linear velocity for putting rope, and drum diameter is becoming Change, the rotating speed of two reel must be different, and therefore, in the application two reels are connected on power transmission shaft by ratchet has There is ingenious part.

A reductor (78) is set to be driven in steel cable drive device, it is not abundanter than selecting at the same speed, artificial pulling force can be mitigated, It is especially suitable for the big running trolley of tonnage.

Track above the application middle girder uses inverted " u "-shaped track, and the wheel of running trolley is bushing to be run in orbit, This spline structure can effectively play anti-roll-over action to running trolley.

Brace and cantilever beam and Holder for hanging household utensiles composition triangular structure in the application cantilever member, make cantilever member rigidity By force, the advantages that stability is good, load-carrying is big；Cantilever beam is made using C-shaped channel steel, it is in light weight, few with material；The axis of rolling is carried on coaster Hold, rotate flexibly, and it is simple in construction, cost is low.

End carriage in the application crane sets anti-tipple (11), crane can be avoided to tumble, and ensures safety；When outstanding When arm beam may overload, end carriage is while upwarp, and now the eave tile of L-shaped safety hook can catch on the upper cover plate Ji of cart support rail beam (12) Edge, avoid crane from tumbling and ensure safety；Anti- tipple is connected with end carriage, in-site installation convenient construction；It is counter to tumble T-shaped on device hooks seat (111) and L-shaped safety hook (112) is designed with connecting elongated hole, in crane in-site installation, is easy to adjust Relative position is saved, easily installation is in place；When crane end carriage upwarps, can be pulled by hinged cantilever component or movement Ring-chain hoist reduces lift heavy, can so change the position of centre of gravity of crane, ensure stabilization, avoid crane from tumbling.

Bearing block and suspension rod axis connection in the application rotating mechanism bear lifting power, thrust bearing installation by thrust bearing Above bearing block, it is easy to dismounting to safeguard；The inner hole structure of bearing block is simply easy to process；Sleeve (43) is that high-abrasive material is slided Dynamic bearing uses, and reduces the fit clearance of suspension rod axle, increases rotational stabilization and axiality, and cantilever member rotates laborsaving；It is locking After nut and suspension rod axis connection, then the connection by bolt (46), anti-loose effect is played, ensures rotating mechanism safety.
