[0026] figure 1 The schematic structure of the wire rope cleaning apparatus 1 which concerns on one Example of this invention is shown. The wire rope cleaning device 1 has a wire rope cleaning part 2, which is composed of an elastic body with a split structure, and engages with the circumferential spiral unevenness of the wire rope 6 to sandwich the wire rope 6 in order to remove oil from the surface of the wire rope 6. set up. The elastic body is formed of a material such as a resin material or a rubber material.

[0027] In order to press the steel wire rope cleaning part 2 of the split structure as an elastic body on the outer circumference of the steel wire rope 6, there is also a cleaning part pressing part 3 of the split structure, which has a size tangent to the outer diameter of the wire rope cleaning part 2. The inner diameter is such that the wire rope cleaning part 2 can engage with the helical unevenness on the surface of the wire rope 6 to perform cleaning. In ...

Abstract

Of wire rope cleaning case of the present invention provides a wire rope cleaning tool, even in the case that a plurality of elevator rope as disposed adjacent to each other, can be provided without being affected by adjacent in the rope. Wire rope cleaning tool of the present invention includes: a cleaning unit, which is constituted by an elastic member in a spiral manner with a convex engaging surface of the wire rope provided; the pressing portion, so as to cover the cleaning unit is provided for the said cleaning portion fixed to the rope; and a mounting bracket, which limits the cleaning portion and the pressing portion of the movable range in the longitudinal direction of said rope, said fixing bracket in a longitudinal direction of the rope to sandwich the cleaning portion and the pressing portion are disposed below the upper portion and the cleaning of the pressing portion, on each of the other fixing bracket is provided adjacent to the wire rope to prevent the wire rope and the pressing portion in contact with the guide wire rope occurs.

Description

technical field [0001] The invention relates to a steel wire rope cleaning device and an elevator maintenance tool. Background technique [0002] In general, steel wire ropes used in elevators, elevators, cable cars, or cranes are formed by twisting a plurality of strands of steel wires twisted together, so there are spiral irregularities in the length direction. The wire rope is coated with oil to prevent abrasion and rust. With long-term use, dust and sand and other garbage will adhere to the surface of the wire rope, and the oil on the surface of the wire rope will also harden. At this time, it is necessary to remove the old Oil and apply new oil. When cleaning, it is necessary to remove the oil from the spiral irregularities on the surface of the wire rope, and since it is necessary to clean along the grooves, the operation takes a lot of time. [0003] As a technique for automatically removing oil from the surface of a wire rope, for example, the technique disclosed i...
