Description
Technical Field
The utility model relates to a pulley protector technical field especially relates to a pulley wire rope protector on overhead traveling crane.
Background
When a crown block worker operates the crown block to hoist and rise, if the crown block worker operates the crown block to obliquely pull and the like, the steel wire rope at the position of the upper pulley can be separated from the pulley groove and hung on the pulley shaft, so that the steel wire rope falls off the track and is difficult to find, and the continuous operation can cause the wire breakage and strand breakage of the steel wire rope until the steel wire rope is broken, and the hanging object falling accident.
The pulley on the overhead traveling crane at present does not have the protection or welds a fender rod and protects, and the protective effect is poor.
SUMMERY OF THE UTILITY MODEL
In view of this, for solving the not enough of existence among the above-mentioned background art, the utility model provides a pulley wire rope protector on overhead traveling crane, no matter how operate can both guarantee that wire rope gets into the pulley groove perpendicularly, avoids wire rope to fall the way.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a pulley wire rope protector on overhead traveling crane, including set up the under casing on the automobile body with set up in last protection casing on the top sheave, the under casing adopts welding mode fixed with the automobile body, go up the connecting plate that protection casing and under casing pass through on the protection casing and carry out bolted connection, go up the protection casing with the under casing with leave the clearance between the top sheave, be provided with on the under casing with the corresponding grooving of pulley groove on the top sheave.
Preferably, the upper shield and the lower shield are rolled from a steel plate having a thickness of 16 mm.
Preferably, the gap has a distance of 5-10 mm.
Compared with the prior art, the utility model, following beneficial effect has:
1. the utility model provides a pulley wire rope protector on overhead traveling crane, through the corresponding grooving of grooving on the lower protective cover and the upper pulley of offering on the lower protective cover, wire rope gets into the grooving on the upper pulley through the grooving on the lower protective cover in, fixes a position earlier by the grooving before getting into the grooving, regardless of how askew draw and drag wire rope to one side, can both guarantee that wire rope gets into the grooving perpendicularly, has avoided wire rope to deviate from the grooving and has fallen to say.
2. The utility model provides a pulley wire rope protector on overhead traveling crane, through the last protection casing that sets up with set up the connecting plate bolted connection on the upper pulley, only need demolish connecting bolt and just can pull down the last protection casing when repairing the upper pulley, the maintenance upper pulley.
