Description

Bearing-free moving single head sheave structure

Technical Field

The utility model relates to a single head sheave that moves about exempts from bearing improvement technique, concretely relates to single head sheave structure that moves about of no bearing.

Background

The head sheave of the single-rope winding type mine hoist is limited by a spatial position, and simultaneously meets the requirement that the deflection angle from the central line of the head sheave to any rope blocking plate of a hoist drum is less than 1 degree and 30 degrees, so that the single head sheave is designed into a moving head sheave, the moving distance is related to the spatial distance from the head sheave to the hoist, the moving head sheave drives a copper tile to move on a head sheave shaft, and the head sheave shaft simultaneously drives a bearing inner ring to rotate, so that a steel wire rope drives the moving head sheave to rotate on the head sheave shaft sometimes and does not rotate sometimes; at the moment, because the steel wire rope and the movable wheel are not synchronous, the steel wire rope is likely to bounce out of a head sheave rope groove and directly fall on a head sheave shaft to scratch the head sheave shaft, and safety production is affected.

Referring to fig. 1, in the original single head sheave design, no matter the fixed head sheave or the moving head sheave, both include a rolling bearing (or a sliding bearing), and in actual operation, the fixed head sheave drives a head sheave shaft 5 to synchronously operate through a bearing 6, while the moving head sheave 1 with a copper bush 2 passes through the bearing 6 and the head sheave shaft 5, sometimes synchronously operate, sometimes asynchronously operate; compared with a fixed head sheave, the moving head sheave cannot ensure synchronous operation of the head sheave and the head sheave shaft, if the head sheave and the head sheave shaft synchronously operate, namely the brasses and the head sheave shaft synchronously operate, and no relative motion occurs between the brasses and the head sheave shaft, an effective oil film is difficult to form, which is unfavorable for the normal operation of the moving head sheave.
