Abstract
Description
Technical Field
[0001] This utility model relates to the field of maintenance device technology, and in particular to a rapid maintenance device for the wire rope of a gate hoist. Background Technology
[0002] In water conservancy projects, the wire ropes used in gate hoists are typically quite thick. Over time, a large amount of deteriorated maintenance oil accumulates in the gaps between the wire rope strands, along with dust, impurities, and other contaminants. If these contaminants are not cleaned promptly, they will not only accelerate the wear and tear on the wire rope, reducing its service life, but may also affect the safety and stability of the gate's opening and closing.
[0003] Currently, the maintenance of wire ropes for gate hoists is quite cumbersome. Before any new maintenance treatment, dirt must be removed from the surface of the wire rope, but existing cleaning methods are inefficient and inconvenient for effectively removing deteriorated grease from the gaps between the strands. Furthermore, traditional maintenance devices require installation and subsequent dismantling, increasing the workload of workers and reducing maintenance efficiency. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a rapid maintenance device for the wire rope of a gate hoist, which has the advantages of efficiently removing dirt and quickly completing maintenance, thus solving some of the problems mentioned in the background technology.
[0005] This utility model provides the following technical solution: a rapid maintenance device for the wire rope of a gate hoist, comprising a maintenance barrel, a bearing seat fixedly installed at the middle of the upper end of the maintenance barrel, a collar fixedly installed on the inner ring of the bearing seat, and evenly distributed screws threaded through and connected to the collar, with a scraper rotatably installed at the adjacent ends of the screws, a limit ring fixedly connected to the upper end of the collar, the upper end of the scraper fitting against the lower end face of the limit ring, four symmetrically designed rotating shafts rotatably installed near the middle of the interior of the maintenance barrel, irregularly shaped wire brushes fixedly fitted on the upper side of each rotating shaft, and irregularly shaped sponge brushes fixedly fitted on the lower side of each rotating shaft, and through holes with a diameter larger than that of the wire rope provided at the middle of both the upper and lower ends of the maintenance barrel.
[0006] Furthermore, a knob is fixedly installed on the other end of each screw, and there is a certain gap between the scraper and the inner wall of the collar to ensure that the scraper will not damage the maintenance oil on the surface of the wire rope when cleaning is not required.
[0007] Furthermore, an isolation plate is fixedly installed inside the curing barrel near the lower side of the irregularly shaped wire brush, and a sealing plate is fixedly installed inside the curing barrel on both the upper and lower sides of the irregularly shaped sponge brush. A sealing bearing is fixedly sleeved on the rotating shaft at the intersection with the sealing plate. The isolation plate can effectively prevent dirt from contaminating the sealing bearing, and the sealing bearing can prevent curing oil from seeping in and causing waste, while ensuring the normal rotation of the rotating shaft.
[0008] Furthermore, the lower end of each rotating shaft passes through the curing bucket and is fixedly installed with a handle. The lower end of each handle is equipped with a directional indicator, which facilitates the cleaning operation for the staff.
[0009] Furthermore, fixing plates are provided at both ends of the maintenance bucket corresponding to the irregularly shaped wire brushes. A sleeve rail is fixedly installed on the outer side of the maintenance bucket near the middle. A sleeve is slidably installed between the inside of the sleeve rail and the fixing plate. That is, by lifting the sleeve upward, the upper part of the maintenance bucket can be opened, thereby cleaning the dirt that has fallen onto the isolation plate. The fixing plate can improve the connection stability between the upper cover plate and the lower part of the maintenance bucket.
[0010] Furthermore, a feeding port is provided at one end of the curing barrel near the lower side of the upper sealing plate, and mounting plates are symmetrically installed on the curing barrel near the lower side. The mounting plates can be fixed to the frame of the gate hoist base by using a suitable bolt assembly.
[0011] The advantages of this utility model are as follows:
[0012] 1. The scraper in this device can precisely fit into the gaps between the wire rope strands. During the descent of the wire rope, it can rotate along the wire rope's grain by means of friction and limiting force. Without an additional power source, it can effectively scrape away the deteriorated grease and dirt in the gaps, solving the problem of difficult-to-clean dirt in the gaps between the wire rope strands. The device has a clever structure and strong practicality, improving the cleaning effect on the wire rope.
[0013] 2. By rotating the shaped sponge brush, the absorbed maintenance oil can be evenly applied to the outside of the wire rope, achieving efficient maintenance. When no protective operation is required, simply rotate the handle to separate the shaped sponge brush from the surface of the wire rope. There is no need to repeatedly disassemble and reassemble the device. The operation is simple and quick, effectively saving maintenance time and labor costs, and improving the maintenance efficiency of the wire rope. Attached Figure Description

Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-4A rapid maintenance device for the wire rope of a gate hoist includes a maintenance tank 1. A bearing seat 2 is fixedly installed at the middle of the upper end of the maintenance tank 1. A collar 3 is fixedly installed on the inner ring of the bearing seat 2. Evenly distributed screws 4 are threaded through and connected to the collar 3. Scraper pieces 5 are rotatably installed at the near ends of the screws 4. A limit ring 6 is fixedly connected to the upper end of the collar 3. The upper end of the scraper piece 5 is in contact with the lower end face of the limit ring 6. Inside the maintenance tank 1, four sets of symmetrically designed rotating shafts 8 are rotatably installed near the middle. Each rotating shaft 8 is fixedly fitted with a [missing information - likely a device name or component] near the upper side. A shaped steel wire brush 9 and a shaped sponge brush 10 are fixedly fitted on the shaft 8 near the lower side. The upper and lower ends of the curing barrel 1 have through holes with a diameter larger than the steel wire rope at their midpoints. A knob 7 is fixedly installed on the other end of the screw 4. A certain gap exists between the scraper 5 and the inner wall of the collar 3, allowing the steel wire rope to pass through the through holes at the upper and lower ends of the curing barrel 1, as well as the isolation plate 11 and sealing plate 12. Curing oil for the steel wire rope is poured into the curing barrel 1 through the feeding port 16. Turning the handle 14 drives the shaft 8 to rotate, which in turn drives the shaped steel wire rope... The wire brush 9 and the irregularly shaped sponge brush 10 rotate. Following the direction indicator 15 at the lower end of the handle 14, the operator can rotate the protruding ends of the irregularly shaped wire brush 9 and the irregularly shaped sponge brush 10 to the wire rope. Turning the knob 7 rotates the screw 4, which in turn moves the scraper 5, allowing it to be pressed into the gap between the strands of the wire rope. The limiting ring 6 limits the scraper 5 to maintain stability and prevents it from rotating under stress and shifting away from the gap between the strands. Furthermore, during the process of opening and closing the machine to lower the wire rope... The limiting ring 6 can initially scrape away larger foreign objects adhering to the wire rope, and the scraper 5 can scrape away the deteriorated grease in the gaps between the wire rope strands. The design of the bearing seat 2 allows the scraper 5 to rotate along the texture of the wire rope during its descent, thus ensuring the scraper 5 can effectively remove dirt from the gaps between the wire rope strands. At the same time, this device directly drives the scraper 5 to rotate by the friction between it and the wire rope, as well as by the limiting effect, without the need for an additional power source to drive the scraper 5 and other structures to rotate. The structure is ingenious and practical.
[0021] Please see Figures 1-4Inside the curing bucket 1, a partition plate 11 is fixedly installed near the lower side of the irregular steel wire brush 9. Inside the curing bucket 1, sealing plates 12 are fixedly installed on both the upper and lower sides of the irregular sponge brush 10. Sealing bearings 13 are fixedly sleeved on the rotating shaft 8 at the intersection with the sealing plates 12. The lower end of the rotating shaft 8 passes through the curing bucket 1 and is fixedly installed with a handle 14. A pointer 15 is provided at the lower end of each handle 14. Fixing plates 17 are provided at both ends of the curing bucket 1, corresponding to the irregular steel wire brush 9. A sleeve rail 18 is fixedly installed on the outer side of the curing bucket 1 near the middle. A sleeve 19 is slidably installed between the inside of the sleeve rail 18 and the fixing plate 17. A feeding port 16 is provided at one end of the curing bucket 1 near the lower side of the upper sealing plate 12. A feeding port 16 is provided on the curing bucket 1 near the lower side. The device is equipped with an installation plate 20. As the wire rope continues to descend, the shaped wire brush 9 not only removes residual dirt from the gaps between the strands, but also performs further fine cleaning on its surface. When the wire rope reaches the shaped sponge brush 10, the sponge brush 10 absorbs the maintenance oil and applies it evenly to the outside of the wire rope through the squeezing action, thus providing protection. When protection is not required, the scraper 5 is separated from the wire rope by turning the knob 7, and the convex surfaces of the shaped wire brush 9 and the sponge brush 10 are rotated to the other side by turning the handle 14 to separate them from the surface of the wire rope. The operation is simple and quick, without the need for repeated disassembly and assembly of the device, greatly improving the efficiency of wire rope maintenance for workers.
[0022] Working principle: The wire rope passes through the through holes at both ends of the curing barrel 1, as well as the isolation plate 11 and sealing plate 12. Curing oil for the wire rope is poured into the curing barrel 1 through the feeding port 16. Turning the handle 14 drives the rotating shaft 8, which in turn rotates the shaped wire brush 9 and the shaped sponge brush 10. The indicator 15 at the lower end of the handle 14 helps the operator rotate the protruding ends of the shaped wire brush 9 and the shaped sponge brush 10 towards the wire rope. Turning the knob 7 drives the screw 4, which in turn moves the scraper 5, allowing it to press against the gap between the strands of the wire rope. The limiting ring 6 limits the scraper 5 to maintain stability and prevents it from rotating under stress and shifting away from the gap. Furthermore, during the descent of the wire rope when the opening and closing mechanism is activated, the limiting ring 6 initially removes any remaining residue adhering to the wire rope. Large foreign objects are removed by scraping the scraper 5, which can remove deteriorated grease from the gaps between the wire rope strands. The design of the bearing seat 2 allows the scraper 5 to rotate along the grain of the wire rope during its descent, ensuring the scraper 5 can effectively remove dirt from the gaps between the wire rope strands. As the wire rope continues to descend, the shaped wire brush 9 not only removes residual dirt from the gaps between the strands but also performs further fine cleaning on its surface. When the wire rope reaches the shaped sponge brush 10, the sponge brush 10 absorbs the maintenance oil and applies it evenly to the outside of the wire rope through the squeezing action. When no protective operation is required, the scraper 5 is separated from the wire rope by turning the knob 7, and the convex surfaces of the shaped wire brush 9 and the sponge brush 10 are rotated to the other side by turning the handle 14 to separate them from the surface of the wire rope.
