Abstract
Description
Technical Field
[0001] This utility model belongs to the field of maintenance equipment for hydropower station gate winches, and in particular relates to a coating device for the end wire rope of a hydropower station gate winch. Background Technology
[0002] Currently, the wire ropes of hydropower station gate winches are mainly maintained by manually applying special lubricating grease periodically to slow down wear, prevent corrosion, and extend service life. However, the existing application method has significant limitations. Operators can usually only apply grease to the winch drum section and the nearby accessible part of the wire rope. The end section of the wire rope, suspended vertically downwards from the drum to the gate body (especially in high-altitude or deep-well gate applications), is difficult to access, resulting in chronically insufficient lubrication. This problem is particularly pronounced in hydropower environments with humid conditions, high sediment content, or corrosive media. Unlubricated sections of the wire rope are prone to corrosion, broken strands, and even breakage, seriously affecting the safe operation of the gate. Lowering workers to the end section of the wire rope using a suspended platform for lubrication requires specialized equipment, incurs high maintenance costs, and poses safety hazards due to working at height. Utility Model Content
[0003] The purpose of this invention is to provide a coating device for the end wire rope of a hydropower station gate winch. This invention has the advantages of high lubrication efficiency, high operational safety, and low maintenance costs.
[0004] The technical solution of this utility model is as follows: A wire rope coating device for the end of a gate winch in a hydropower station includes a tubular body. The inner side of the tubular body is provided with two brush areas, one above the other. Both the upper and lower sides of the brush areas form oil storage areas. The tubular body is composed of two segments. The common side of the two segments is hinged, and the common other side of the two segments is detachably connected.
[0005] In the aforementioned hydropower station gate winch end wire rope coating device, the upper end of the tubular body is provided with an upper lifting lug.
[0006] In the aforementioned wire rope coating device for the end of the gate winch of the hydropower station, the lower end of the tubular body is provided with a lower lifting lug.
[0007] In the aforementioned wire rope coating device at the end of the gate winch of the hydropower station, a sealing element is provided on the joint surface of the two segments.
[0008] In the aforementioned wire rope coating device at the end of the gate winch of the hydropower station, the upper and lower ends of the inner hole of the tubular body are provided with rounded corners.
[0009] In the aforementioned wire rope coating device at the end of the gate winch of the hydropower station, the common side of the two segments is hinged by a hinge, and the common other side of the two segments is connected by a snap fastener.
[0010] Compared with existing technologies, the tubular body of this invention can be opened, filled with grease, and then closed to the end of the wire rope. After connecting the traction rope to the tubular body, the tubular body can be pulled back and forth in the winch room. A brush inside the tubular body evenly coats the end of the wire rope with grease, preventing localized corrosion and wear, effectively extending the service life of the wire rope, and providing high lubrication efficiency. Since applying grease to the end of the wire rope does not require workers to enter the suspended platform for high-altitude operations, the operation is safer, and no corresponding lifting equipment is needed, resulting in lower maintenance costs. It is particularly suitable for the maintenance of winch wire ropes in remote hydropower stations or small hydropower stations. In summary, this invention has the advantages of high lubrication efficiency, high operational safety, and low maintenance costs. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0016] Example: A coating device for the end wire rope of a gate winch in a hydropower station, such as... Figure 1 As shown, it includes a tubular body, with rounded corners 7 at both the upper and lower ends of the inner hole of the tubular body, an upper hanging lug 4 at the upper end of the tubular body, and a lower hanging lug 5 at the lower end of the tubular body.
[0017] The inner side of the tubular body is provided with two brush areas 1, one above the other. Each brush area 1 consists of multiple brushes, with the inner ends of the brushes pointing perpendicularly to the axis of the tubular body. The outer ends of the brushes are fixed to the inner wall of the tubular body. Oil storage areas 2 are formed on both the upper and lower sides of the brush areas 1. The tubular body is composed of two segments 3. Oil-resistant sealing elements 6, such as fluororubber strips or nitrile rubber strips, are provided on the mating surfaces of the two segments 3. The common side of the two segments 3 is hinged by a hinge 8, and the common other side of the two segments 3 is connected by a snap fastener 9.
[0018] Instructions for use: Release the latch 9, open the two segments 3, inject grease into the oil reservoir 2, and align the two segments 3 with the end of the winch wire rope as the center. The inner end of the brush should contact the wire rope, and the tubular body should be re-established using the latch 9. Attach the traction rope to the upper lifting lug 4, and connect the lower lifting lug 5 to the counterweight via a rope. Hold the traction rope, and the brushing device will slide down the wire rope under the weight of the tubular body and the counterweight. The grease in the oil reservoir 2 will be applied to the wire rope by the brush in the brush area 1. Move the tubular body up and down several times using the traction rope to ensure even application of grease to the end of the wire rope. The rounded corner 7 ensures smooth lifting and lowering of the tubular body while preventing cuts to the wire rope.
[0019] This utility model is a solution proposed based on technical problems discovered in actual production. It has now been transformed into a practical application in actual production, and its technical effects have been verified.
[0020] This utility model device has a simple structure and flexible operation. It can accurately cover the suspended section of the wire rope that is difficult to reach by traditional manual brushing, ensuring that the grease is evenly coated on the entire wire rope, avoiding local rust and wear, effectively extending the service life of the wire rope, and reducing the frequency of replacement and maintenance costs.
[0021] This invention improves the safety and convenience of wire rope lubrication operations for winches, reducing the risks associated with manual operation. Traditional methods of painting suspended sections at height require manual climbing or hoisting equipment, posing safety hazards such as falls and slippage. This invention employs a hinged, split-connection design, allowing operators to perform painting and maintenance on the suspended section of the wire rope from a safety platform in the winch room using a traction rope and counterweight. This significantly reduces the risks of working at height while simultaneously improving lubrication efficiency.
[0022] This invention features a simple and reliable structure, adapts to complex working conditions, and is easy to promote and use. Compared to the high cost and complex maintenance of automated lubrication systems, this invention is lightweight, flexible in installation, and requires no external power source. It is particularly suitable for the maintenance needs of hydropower stations or small water conservancy facilities in remote areas, and has high practicality and economy.
[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
