Description
Technical field
The utility model belongs to crane technical field more particularly to a kind of modularized production pulley blocks.
Background technique
Whip-gin group is the fixation pulley of suspension hook group cooperating, is fixed in structure, by several fixed pulleys and
Running block at.Pulley blocks are used widely in the machinery such as crane, hoist engine, elevator, are the important of hoisting machinery
One of component.
In whip-gin group, usually there is rope race, wirerope is normally in rope groove.Current whip-gin
More built on the sand, during the decline of crane hook group, the wirerope in rope groove is easy to happen disorder cable to group structure, is detached from rope
Slot, after crane hook group slings weight, wirerope will be rolled with the rotation of pulley, occur being difficult to rope rolling, steel wire
Rope gets over rope outlet groove and there is a phenomenon where security risks, and existing pulley blocks may cause Caton after prolonged use, sliding
Wheel rotation is inconvenient, it is therefore necessary to improvement is designed to it.
Summary of the invention
The utility model is to solve well-known technique and provide a kind of modularized production pulley blocks.
The utility model is adopted the technical scheme that solve well-known technique: a kind of module metaplasia
Pulley blocks, including pulley, shield, hook and shaft are produced, the shaft is equipped with multiple pulleys, and the lower section of the pulley is equipped with
Shield, the shield both ends are connect with shaft, and the rear end of the shield is equipped with anti-drop device, under the two sides of the shaft
End is equipped with connecting rod, and the lower end of the connecting rod is fixedly connected with bottom plate, the hook upper end through bottom plate and pass through nut into
Row is fixed.
Further, the anti-drop device is made of side plate, connecting shaft and roller, and the side plate is set to the two of connecting shaft
It holds, is cased with roller on the outside of the connecting shaft.
Further, the inside of the pulley is equipped with oil pocket, and the middle position of the pulley, which is equipped with, is connected with the rotating shaft set
Hole, the hole wall of the sets of holes are equipped with oil seepage hole, are equipped with lubricating oil in the oil pocket.
Further, the height of the lubricating oil is lower than the bottom surface of sets of holes.
Further, the quantity of the pulley is 3.
Further, the surface of the roller and pulley contact.
The utility model has the advantage that as follows with good effect:
1. the utility model proposes a kind of modularized production pulley blocks, pass through protective plate rear side be arranged anticreep fill
It sets, and the roller and pulley contact of the anti-drop device, this kind design effectively avoids lifting rope from falling off, guarantees the safety used, drops
Lower security hidden danger.
2. the utility model proposes a kind of modularized production pulley blocks, by being arranged oil pocket inside pulley, and with turn
The sets of holes inner wall of axis connection is equipped with oil seepage hole, this kind design, when pulley rotation, lubricating oil can be lubricated by oil seepage hole, from
And pulley and axis friction is avoided to generate noise, influence using effect.
