Description

Grease applicator of wire rope

The present invention relates to a device for applying grease to the surface portion of the wire rope, and more particularly, to enable the application of grease of uniform thickness over the entire circumferential direction to the surface portion of the wire rope to reduce wear of the wire rope. The present invention relates to a grease applicator of a wire rope that can be effectively prevented.

In general, an unloader for unloading raw materials, a stacker for loading raw materials in a yard, and a reclaimer for discharging the stacked raw materials include wire ropes, which are one of the equipment driving elements. Wire rope) and grease is applied to the surface of the wire rope to prevent wear.

In general, as shown in FIG. 1, when the wire rope 2 moves through a rotating drum or sheave 1, friction inevitably occurs due to contact with the rotating structure, and in particular, a long time is installed. In the case of operating the wear, the wear progresses rapidly, and such wear is first made from the strand of the strand forming the outer surface portion of the wire rope 2, and the strand is cut, and the inner core is protruded to be chained. In other words, the remaining strands also start to burst and the entire wire rope 2 is cut.

Conventionally, in order to prevent this, grease was applied on the upper part of the wire rope 2 through the grease supply pipe 3, and when the wire rope 2 vibrated, in particular in the left and right directions on the drawing, grease (4) was applied. ) Is knitted on only one side, whereby grease is applied only to a part of the wire rope 2, and the majority flows down. In other words, uneven wear caused by ton oil is generated and grease that flows out becomes a waste factor.

In addition, in the conventional case where the grease supply pipe 3 is located on the upper part of the wire rope 2, the lower part of the wire rope 2 which is in direct contact with the sheave 1 (the portion indicated by "A" in the drawing) Very little grease is applied, causing uneven wear rapidly.

When wear occurs like this, the replacement cycle of the wire rope 2 is shortened, which leads to a decrease in productivity due to equipment stoppage for replacement, and excessive time and labor for facility maintenance and maintenance. If the monitoring is not made, there was a problem causing a large accident that the wire rope (2) is cut.

The present invention has been made to solve such a conventional problem, and its object is to apply a uniform and necessary amount of grease to the entire outer surface of the wire rope to effectively prevent wear of the wire rope and waste of grease. The present invention provides a grease applicator for wire rope having been removed.
