Movable pulley traction connecting device used for inclined drift transportation heavy equipment

Abstract

A movable pulley traction connecting device used for inclined drift transportation heavy equipment is composed of an auxiliary transport cart and a movable pulley unit which is arranged on the upper portion of the auxiliary transport cart and hinged to the auxiliary transport cart, wherein a connecting hole is formed in a connecting plate at the rear end of a pulley frame of the movable pulley unit, the front end of the pulley frame is composed of an upper supporting plate and a lower supporting plate, a mandrel is arranged in a shaft hole of the pulley frame, a stop collar, a rope sheave and a thrust bearing are sequential arranged between the upper supporting plate of the pulley frame and the lower supporting plate of the pulley frame in series from top to bottom, the rope sheave can rotate around the mandrel between the upper supporting plate of the pulley frame and the lower supporting plate of the pulley frame, rope blocking rollers are arranged on the left side of the pulley frame and the right side of the pulley frame respectively, and rope supporting rollers are arranged on the left side of the front end of the pulley frame and the right side of the front end of the pulley frame in an inclined mode respectively. When the movable pulley traction connecting device is used for the inclined drift transportation heavy equipment, a steel wire rope is twined on the rope sheave through a rope groove, rope ends are fixed near a winch, the connecting hole in the rear end of the pulley frame is used for being connected with a heavily loaded vehicle, therefore, the transportation capacity of the winch is doubled, and the whole machine transportation requirement for some heavy equipment can be met.

Description

Technical field [0001] The invention relates to a movable pulley traction connection device for transporting heavy equipment in inclined lanes, and belongs to the field of mine track auxiliary transport equipment. Background technique [0002] At present, mine coal mining equipment is developing in the direction of high power and heavy duty. The weight of some heavy equipment exceeds the design capacity of the inclined roadway transport winch of some mines. For example, the single weight of hydraulic supports used in some fully mechanized mining faces exceeds 40 tons, which brings difficulties to the transportation of such heavy equipment. In order to solve this transportation problem, many mines adopt the method of "breaking the whole into parts", that is, dismantling the equipment into several units on the well and transporting them to the working position in batches before reassembling. It is advisable to consider the dismantling and assembly of equipment that is larger ...
