The lower mounting frame is composed of a U-shaped plate, a fixing hoop and a connecting hoop, the U-shaped plate is provided with a two-fold plate part and a top plate part, the two-fold plate part is respectively fixed on the side wall of the chain storage barrel, a through hole is formed in the top plate part, the periphery of the through hole is welded and fixed with the hoop on the top surface of the top plate part, the lower end of the chain guide pipe is fixed through the fixing hoop and the connecting hoop, and the lower port of the chain guide pipe is right opposite to the through hole.
The guide ball is a whole ball.
The guide ball is a hemisphere with an upward spherical surface.
Compared with the prior art, the utility model has the advantages of as follows and positive effect:
the utility model discloses the direction ball of addding is fixed in storing the chain bucket, when falling the chain, before the jack-up chain collects and stores in the chain bucket, make the jack-up chain encircle all the time evenly and store the chain bucket and pile the chain under the radial guide effect of direction ball, for prior art, the area of piling the chain has been increased effectively, the inner wall of storing the chain bucket is continuously approached easily constantly to the jack-up chain that piles up, therefore, the effective volume utilization ratio of storing the chain bucket is high, correspondingly, the height of lifting by crane has been improved, the drawback that prior art jack-up chain piled up too concentrated has been overcome.
In summary, in the technical field of the electric chain hoist special for the wind driven generator cabin, the arrangement of the guide balls achieves unexpected technical effects for technicians in the field, so that the chain stacking area of the chain storage barrel with a certain volume can be effectively increased, namely the occupation ratio of the chain stacking volume to the chain storage barrel volume is high, and the purpose of increasing the lifting height of the electric chain hoist is achieved.
