[0002] The workover rig is the most basic and main power source for well repair and underground operation. According to its operating structure, it is divided into two types: crawler type and tire type. In the process of operation, the workover rig needs to use wire rope for traction in order to achieve a certain traction force. During the long-term use of the wire rope, the surface of the wire rope will be adhered to oil stains, and the oil stains will adhere to the surface of the wire rope after contacting with dust. In order not to affect the subsequent use, the wire rope needs to be cleaned, but the existing wire rope cleaning device still has some problems when used:

[0003] Poor cleaning effect. During the cleaning process, the existing wire rope cleaning device cannot effectively clean the blind spots due to the twisting and gaps of the wire rope, which makes the overall cleaning effect fail to meet expectations. Utility Model Content

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Embodiment 1:

[0025] A cleaning device for a workover winch wire rope, this embodiment is based on the problem of wire rope surface cleaning, in order to achieve efficient cleaning, such as Figure 1-4 As shown, it includes a rectangular fixed plate 1, a support platform 2 is fixed to the top outer wall of the rectangular fixed plate 1, and a rotating unit is arranged on the support platform 2, the rotating unit includes an arc-shaped slide groove 3 opened on the top outer wall of the support platform 2, and the inner wall of the arc-shaped slide groove 3 is slidably inserted with sliding blocks 4 distributed at equal distances, a plurality of the sliding blocks 4 are welded to the outer wall of the same cleaning roller 5, and a worm gear 10 is arranged on the outer wall of one side of the cleaning roller 5, the bottom of the worm gear 10 is meshed and driven with a worm 11, and the worm 11 is connected to a servo motor 12, and a cleaning unit is arranged inside the cleaning roller 5;

[0026] By inserting equally spaced arc-shaped cleaning brush plates 8 into the inner wall of the cleaning roller 5 and rotating them in the direction of the wire rope grain, the mud stains in the dead corners and gaps of the wire rope can be scrubbed and cleaned, and by spraying water with the nozzles 14 at both ends, the wire rope can be effectively cleaned.

[0027] The cleaning unit comprises an arc-shaped slot 6 which is equidistantly provided on the inner wall of the cleaning roller 5, and an arc-shaped plug-in block 7 is slidably inserted into the inner wall of the arc-shaped slot 6, and an arc-shaped cleaning brush plate 8 is welded to the outer wall of the arc-shaped plug-in block 7, and an outer wall of the cleaning roller 5 which is close to the arc-shaped slot 6 has an external thread groove, and the outer wall of the external thread groove is screwed to a limiting cover plate 9;

[0028] Both ends of the cleaning roller 5 are provided with water pipes 13 which are arranged obliquely, and the water pipes 13 are connected with spray heads 14 .
