Abstract

The invention discloses a novel universal towrope pulley. The novel universal towrope pulley consists of rolling support wheels, horizontal guide wheels and a universal mechanism. In the towrope pulley, four-wheel rolling support wheels are adopted; each horizontal guide wheel is arranged below each rolling support wheel; the lower part of the center of the towrope pulley is provided with the universal mechanism; in the engineering, universal C-type steel is used as a supporting track; and the joint of the track is pulled tightly by a bolt in a plug-in mode. The invention discloses a trolley running cable universal towrope pulley used for a single and double beam type crane of which an electric block is used as a lifting mechanism currently in China, the running deflection of the pulley cannot be generated due to external force, the pulley slides over the joint easily and the blockage phenomenon is avoided.

Description

A kind of novel universal towing cable coaster
Technical field: the present invention relates to a kind of novel universal towing cable coaster.
Background technology: domestic is that beam, the transfer crane kind of lifting mechanism has: electric single-beam overhang crane, mono beam overhead crane, electric block double girder crane and electric block transfer crane etc. with the electric block.Supply cable and control cable when electric block moves on beam mainly support with steel rope, follow dolly by sliding wheel suspention cable and run.There is following shortcoming in cable handler at present: 1. after long-time the use, steel rope is easy to rub, the safety misadventure that causes cable to drop; 2. be slider roller owing to what adopt, friction drag is big, especially for the large span hoisting crane, the tension vertical line of steel rope is very big, very not attractive in appearance on the one hand, slider roller is in operation and the heavy grade climbing occurs on the other hand, has increased the resistance of trolley travelling, easily cause the deflection of trolley travelling, thereby make dolly the rail phenomenon occur gnawing.
Summary of the invention: purpose of the present invention will provide a kind of novel universal towing cable coaster exactly, and it can overcome the existing defective of above cable handler well.The object of the present invention is achieved like this, a kind of novel universal towing cable coaster, be made up of rolling support wheel, horizontal guide sheave, omnidirectional mechanism, it is characterized in that: the towing cable coaster adopts four-wheel rolling support wheel, and every rolling support wheel below is provided with horizontal guide sheave; Towing cable coaster central authorities below is provided with omnidirectional mechanism; In engineering, adopt general C shaped steel as supporting track; Rail joint adopts plug-in type to add the bolt tension.The present invention a kind ofly is used for to be the universal towing cable coaster of trolley travelling cable of single two-beam type hoisting crane of lifting mechanism with the electric block, can to guarantee that coaster can be because of external force produces the operation deflection that coaster easily rolls across in the joint, the jam phenomenon can not occur at present domestic.

Fig. 2 is the right elevation in the structural representation of the present invention;
Fig. 3 is the use legend of the present invention in engineering;
1. rolling support wheel; 2. horizontal guide sheave; 3. omnidirectional mechanism; 4. track; 5. fixed end; 6. joint and suspension bracket; 7. Universal scooter; 8. universal towing cable coaster.
The specific embodiment: the invention will be further described below in conjunction with accompanying drawing;
A kind of novel universal towing cable coaster is made up of rolling support wheel 1, horizontal guide sheave 2, omnidirectional mechanism 3, it is characterized in that: the towing cable coaster adopts four-wheel rolling support wheel 1, and every rolling support wheel 1 below is provided with horizontal guide sheave 2; Towing cable coaster central authorities below is provided with omnidirectional mechanism 3; In engineering, adopt general C shaped steel as supporting track 4; Track 4 joints adopt plug-in type to add the bolt tension.During concrete enforcement, cable flexible is that the push-and-pull by universal towing cable coaster realizes.Generally speaking when track length is long, generally greater than 22.5m.Along with the increase of coaster quantity, the tractive force of towing cable coaster obviously increases, and rail joint quantity increases simultaneously, causes the jam probability occurring in the joint and heightens, and cable is broken.Its reason be cable when bending, coaster is produced horizontal torsion power, cause the coaster horizontal torsion, make rolling support wheel and track produce cliding friction, need only the joint unfairness simultaneously, will be stuck in the joint.So the present invention is owing to designed omnidirectional mechanism between cable and C type track, the horizontal torsion power of cable obtains balance at the omnidirectional mechanism place, can not pass to coaster, thereby guarantee that coaster can be because of external force produce the operation deflection, the lashed cable height of cable can be reduced to minimum simultaneously; When there is certain unfairness at the rail joint place, because the effect of horizontal guide sheave has guaranteed that coaster easily rolls across in the joint, the jam phenomenon can not appear.The present invention can be guaranteed by condition of service on the cucurbit twin beams of span 47m.
