SLEEVE DETACHING APPARATUS FOR MINING HYDRAULIC SUPPORT

摘要

A sleeve detaching apparatus for a mining hydraulic support comprises a hoop-shaped fixing base and an annular rotary sleeve. Two parts of the fixing base are connected by means of bolts. The outer wall of the fixing base extends outwards to form a jack mounting rod. The jack mounting rod is hinged with the bottom of a jack. The rotary sleeve is coaxially mounted with the fixing base. The outer wall of the rotary sleeve is hinged with a telescopic shaft of the jack. The sleeve detaching apparatus for a mining hydraulic support can be used for detaching the guide sleeve for a hydraulic support upright conveniently and quickly while saving time and labor, thereby improving the maintenance efficiency and reducing the maintenance cost.
