Description

Technical Field

[0001] The present invention belongs to the technical field of wire rope maintenance equipment, and particularly relates to a wire rope maintenance equipment and a maintenance method. Background Art

[0002] Wire ropes are widely used in lifting, traction, tensioning and load bearing, such as the wire ropes of the sluice hoist in water conservancy and hydropower projects. The working environment of such wire ropes is relatively harsh, being exposed to humid and salt spray environments for a long time, resulting in problems such as rust, adhesion of dirt, wear and internal wire breakage. Therefore, regularly providing good maintenance for wire ropes is an important activity to ensure the quality of wire ropes and improve the safety and stability of system operation.

[0003] There are various existing devices for maintaining wire ropes. For example, in the specification of Chinese invention patent CN117983457B, a wire rope maintenance device is disclosed, in which a rectangular spray pipe is used to spray lubricating oil onto the wire rope. Another example is that in the specification of Chinese invention patent CN116463770A, a wire rope maintenance device is disclosed, in which a cleaning ring is first used to clean the surface sludge of the wire rope and then lubricating oil is applied to the surface of the wire rope. The foregoing maintenance devices have the following problems: First, the existing maintenance devices are usually fixed facilities, requiring the wire rope to pass through the device stably, and providing maintenance functions for the wire rope on the passing path. However, in some scenarios, such as the wire ropes of the aforementioned water conservancy and hydropower hoists, such fixed facilities cannot be applied. Second, the existing devices cannot provide sufficient cleaning of the wire rope and cannot fully remove the surface attachments, which results in the subsequent lubricating oil not being able to fully infiltrate into the wire rope. Third, the existing maintenance devices cannot perform quality inspection on the wire rope (referring to detecting internal wire breakage conditions) and cannot discover potential problems of the wire rope.

[0004] In summary, it is necessary to develop and design a new type of wire rope maintenance equipment to solve the aforementioned technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a wire rope maintenance equipment, which has the ability to actively climb and shift on the wire rope, improves the infiltration effect between the lubricating grease and the wire rope by thoroughly cleaning the wire rope before applying oil, thereby improving the maintenance effect of the wire rope, and simultaneously performs quality inspection on the wire rope during the maintenance process to timely discover and mark the defect positions on the wire rope.

[0014] The object of the present invention is to provide a maintenance method based on the foregoing steel wire rope maintenance equipment, including the following steps:

[0015] Step S1: Load the maintenance equipment to the maintenance starting position on the steel wire rope and lock the first pipe shell and the second pipe shell. Operate the climbing assembly, and the two climbing assemblies clamp the steel wire rope and drive the maintenance equipment to move along the steel wire rope towards the maintenance end position;

[0016] Step S2: Start the dry ice cleaning assembly. Compressed air transports the dry ice particles to the cleaning nozzle and sprays them at high speed towards the steel wire rope, applying a dry ice cleaning effect on the steel wire rope. At the same time, start the rotary brush cleaning assembly to apply a rotary brush cleaning effect on the steel wire rope;

[0017] Step S3: Start the oiling assembly. The lubricating grease is extruded and transported to the oiling nozzle, and the lubricating grease discharged from the oiling nozzle is applied to the steel wire rope that has been cleaned;

[0018] Step S4, when reaching the maintenance end position on the wire rope, stop the dry ice cleaning assembly, the brush cleaning assembly, and the oiling assembly, and operate the climbing assembly to reverse and run, so that the maintenance equipment moves along the wire rope towards the maintenance start position;

[0019] Step S5, after reaching the maintenance start position, release the lock between the first pipe casing and the second pipe casing, and disassemble the maintenance equipment from the wire rope.

[0020] Preferably, in step S4, during the return movement from the maintenance end position towards the maintenance start position, start the ultrasonic detector, and continuously inspect the wire rope through the ultrasonic probe. When the ultrasonic detector indicates a quality inspection defect, start the marking assembly, and the colored marking liquid is conveyed to the marking nozzle and sprayed on the wire rope to form a quality inspection color mark, which is used to indicate the position during the later further defect inspection of the wire rope.

[0021] The advantages and positive effects of the present invention are:

[0022] The present invention provides a wire rope maintenance equipment and a maintenance method. Compared with the existing maintenance equipment, the maintenance equipment of the present invention is a controllable mobile maintenance equipment, which can climb and shift along the tensioned wire rope, so it does not depend on the movement of the wire rope, which can expand the application range of the maintenance equipment, and can also perform maintenance operations on some immovable wire ropes (such as wire ropes in the bearing state). The maintenance equipment of the present invention installs a cleaning nozzle at the front and uses a dry ice cleaning assembly to convey a high-speed air flow containing dry ice particles to the cleaning nozzle, applying a dry ice cleaning effect on the surface of the wire rope to promote the peeling of dirt on the surface of the wire rope. On the other hand, a brush cleaning effect is applied to the surface of the wire rope through the brush cleaning assembly. The above two cleaning methods can thoroughly remove the attachments on the surface of the wire rope and improve the surface cleanliness of the wire rope, so that the lubricating grease conveyed to the oiling nozzle by the oiling assembly can better infiltrate into the interior of the wire rope, achieving a better maintenance effect.

[0023] The maintenance equipment of the present invention is equipped with an ultrasonic detector and an ultrasonic probe, so it can continuously perform ultrasonic detection on the wire rope during the movement along the wire rope. Therefore, this maintenance equipment has the ability to simultaneously perform quality inspection on the wire rope during the maintenance process. By setting a marking assembly and a marking nozzle, a color mark is sprayed at the position where the quality inspection defect is detected to provide a position indication for the subsequent further quality inspection of the wire rope.

[0037] To further understand the content, features and effects of the present invention, the following embodiments are provided for detailed description.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 , the steel wire rope maintenance equipment of the present invention includes a first housing 1 and a second housing 2 hinged and connected by a hinge 3, and a lock 4 is provided between the two. As shown in this embodiment, each of the first housing 1 and the second housing 2 includes a semi-tubular housing body, end plates 10 are provided at both the upper and lower ends of the housing body, and a semi-circular notch is provided at the center of the end plate 10. When the first housing 1 and the second housing 2 are closed, the steel wire rope 21 passes through the circular window formed by the two semi-circular notches.

[0039] The first housing 1 and the second housing 2 can be made of aluminum alloy and integrally formed, which can improve the lightweight level of the maintenance equipment and ensure the overall structural strength. As Figure 1 shown, the hinge 3 is located between the inner edges of the first housing 1 and the second housing 2, and the lock 4 is used to lock and fix the closed first housing 1 and the second housing 2. After being locked and fixed, the maintenance equipment is loaded onto the steel wire rope 21, and the two housings can be separated only when the lock 4 is unlocked.Figure 2 the state in Figure 1 is expanded to the state in. The lock 4 includes a side base provided at the outer edge of the first housing 1 and a locking tongue hinged to the side base, and further includes a lock seat provided at the outer edge of the second housing 2. The lock seat includes two relatively arranged lock pieces. When locking, rotate the locking tongue and insert it into the two lock pieces of the lock seat, and then tighten the lock nut on the locking tongue to complete the locking.

[0040] In this embodiment, in order to improve the operation convenience of closing and expanding the first housing 1 and the second housing 2, handles 6 are provided in the middle of the outer edges of both the first housing 1 and the second housing 2. When performing the closing and expanding operations, hold the two handles 6 with both hands respectively. In addition, when this maintenance device is in a non-use state, it can be in the Figure 3 closed state shown in, at this time the two handles 6 are adjacent, making it convenient to carry the maintenance device by hand.

[0041] Two relatively arranged climbing components 5 are installed on the inner walls of the first housing 1 and the second housing 2. The climbing components 5 clamp the steel wire rope 21 and move along the steel wire rope 21. In this way, by operating the two climbing components 5 to act, this maintenance device can climb and shift along the steel wire rope 21, forming a structural design of a maintenance device that can move on the steel wire rope 21 and does not rely on the movement of the steel wire rope 21.

[0042] Please refer to Figure 4 and it can be seen that:

[0043] The climbing component 5 includes a long strip-shaped base 5-1. The base 5-1 is fixedly connected to the connecting seat provided on the inner wall of the housing by bolts. The length direction of the base 5-1 is parallel to the axial direction of the housing.

[0044] A slideway 5-4 is provided in the middle of the base 5-1 and a slide block 5-5 is installed on the slideway 5-4. A support 5-2 is installed at the lower end of the base 5-1 and an electric push rod 5-3 is installed between the support 5-2 and the slide block 5-5. When controlling the piston rod of the electric push rod 5-3 to perform telescopic actions, the slide block 5-5 displaces along the length direction of the slideway 5-4, that is, along the axial direction of the pipe sleeve.

[0045] Two groups of equal-length and parallel support arms 5-10 are used to install a crawler base 5-9 on the upper part of the base 5-1. A crawler 5-8 is installed on the crawler base 5-9, a driving wheel set is installed inside, and a traveling motor 5-7 is installed on the side. A connecting arm 5-6 is installed between the slide block 5-5 and the crawler base 5-9. The traveling motor 5-7 drives the driving wheel set inside the crawler base 5-9 to rotate forward or backward, and correspondingly the crawler 5-8 rotates forward or backward. The width of the crawler 5-8 should be greater than the outer diameter of the steel wire rope 21, so as to ensure the stability and reliability of the combination between the two climbing components 5 and the steel wire rope 21.

[0046] After closing the first shell 1 and the second shell 2, the wire rope 21 is located between the two climbing components 5. First, control the piston rods of the electric push rods 5-3 of the two climbing components 5 to extend synchronously. Since the base 5-1, the crawler base 5-9, and the two groups of support arms 5-10 form a four-bar mechanism, as the slide block 5-5 moves forward, the angle between the support arm 5-10 and the base 5-1 increases, and the crawler base 5-9 and its crawlers 5-8 move towards the center of the shell, that is, towards the wire rope 21. Finally, the wire rope 21 is clamped by the two crawlers 5-8. Then, control the traveling motor 5-7 to move forward or backward, and the maintenance equipment realizes climbing movement on the wire rope 21.

[0047] The pushing and pulling of the crawler base 5-9 by the slide block 5-5 is carried out through the connecting arm 5-6. As Figure 4 shown in the figure, the connecting arm 5-6 has the effect of elastic expansion and contraction. Structurally, it includes a front section with a shaft hole and a rear section with a pin shaft. The pin shaft is inserted into the shaft hole and a spring is provided on the pin shaft. The function is as follows: when the electric push rod 5-3 pushes the slide block 5-5 forward, the crawler base 5-9 and its crawlers 5-8 move towards the center of the shell. When the crawler 5-8 contacts the wire rope 21, the connecting arm 5-6 contracts and its spring contracts, so as to avoid the rigid clamping effect of the two climbing components 5 on the wire rope 21 and avoid the problem of movement jamming caused by rigid clamping.

[0048] At the upper end of the inner cavity of the first shell 1, a detachable probe base 7 with a groove in the middle is provided and an ultrasonic probe is installed. At the upper end of the inner cavity of the second shell 2, a detachable opposing base 8 with a groove in the middle is provided. The ultrasonic probe is used for ultrasonic quality inspection of the wire rope 21 to detect potential internal defects (usually referring to internal wire breakage problems) in the wire rope 21 through ultrasonic detection. After the first shell 1 and the second shell 2 are closed and locked, the probe base 7 and the opposing base 8 are buckled together, and the wire rope 21 is located in the through hole formed by the grooves of the probe base 7 and the opposing base 8, so that it can be ensured that the ultrasonic probe is located on the side of the wire rope 21.

[0049] The function of making the probe base 7 and the opposing base 8 detachable is as follows: different probe bases 7 and opposing bases 8 can be selected and assembled according to the outer diameter of the wire rope 21. The sizes of the central grooves of different probe bases 7 and opposing bases 8 are different. The inner diameter of the through hole formed in the middle should be adapted to the size of the current wire rope 21, and the formed through hole should allow the wire rope 21 to pass through smoothly and shorten the distance between the ultrasonic probe and the wire rope 21 as much as possible. In addition, it is inevitable that the probe base 7 and the opposing base 8 will have a certain degree of wear. After wear, it is necessary to disassemble and replace the probe base 7, its ultrasonic probe, and the opposing base 8.

[0050] At the upper ends of the first housing 1 and the second housing 2, a rotary brush cleaning assembly 9 is installed. At the upper ends of the first housing 1 and the second housing 2, an upper protective cover 12 is also installed, and a cleaning nozzle 11 is installed in the middle of the two upper protective covers 12. The rotary brush cleaning assembly 9 is fixedly installed on the end plates 10 of the first housing 1 and the second housing 2. The lower edge of the upper protective cover 12 is also fixed to the short plate 10, and it can be fixed by welding or screwing. The function of the upper protective cover 12 is to provide lateral protection for the inner rotary brush cleaning assembly 9 and the cleaning nozzle 11 to prevent the rotary brush cleaning assembly 9 and the cleaning nozzle 11 from being knocked. As shown in the figure, the upper protective cover 12 is a hollow structure, so that the debris generated during the continuous cleaning of the wire rope 21 can splash and discharge around.

[0051] Please refer to Figure 5 , it can be seen that:

[0052] The rotary brush cleaning assembly 9 includes a support seat 9-1 fixedly connected to the end plate 10 at the end of the housing. On the support seat 9-1, a swing arm 9-2 is hingedly installed, and a torsion spring 9-3 is installed on the hinge shaft. At the front of the swing arm 9-2, a rotary brush motor 9-6 is provided, and a rotary brush disc 9-5 is installed on the output shaft of the rotary brush motor 9-6. The front end of the swing arm 9-2 is hingedly connected to the side of the housing of the rotary brush motor 9-6, and an adjustable telescopic pull rod 9-4 is installed between the root of the swing arm 9-2 and the side of the housing of the rotary brush motor 9-6. Steel bristles (not shown in the figure) arranged in a spherical fan shape are installed on the rotary brush disc 9-5. When the first housing 1 and the second housing 2 are closed and locked, the steel bristles of the two rotary brush cleaning assemblies 9 clamp the wire rope 21 in the middle, and the high-speed rotating rotary brush disc 9-5 and its steel bristles play a role in continuously rotary brushing and cleaning the wire rope 21.

[0053] Since a torsion spring 9-3 is installed on the hinge shaft between the support seat 9-1 and the swing arm 9-2, the swing arm 9-2, the rotary brush motor 9-6 and its rotary brush disc 9-5 have a certain up and down floating effect. The adjustable telescopic pull rod 9-4 can adjust the length, so the rotary brush motor 9-6 and its rotary brush disc 9-5 can tilt inwards or outwards to adjust the relative distance from the wire rope 21, and by adjusting, the bristles at the end of the steel brush are made to contact the wire rope 21 to ensure the technical effect of rotary brush cleaning.

[0054] At the lower ends of the first housing 1 and the second housing 2, a lower protective cover 13 is also installed. An oiling nozzle 15 is installed in the middle of the two lower protective covers 13, and a marking nozzle 16 is installed in the middle of one of the lower protective covers 13. Among them, the oiling nozzle 15 is used to oil the wire rope 21, and the marking nozzle 16 is used to form a color mark on the wire rope 21. The function of the lower protective cover 13 is to provide lateral protection for the inner oiling nozzle 15 and marking nozzle 16 to prevent the oiling nozzle 15 and the marking nozzle 16 from being knocked. As shown in the figure, the lower protective cover 13 is a hollow structure. In this way, when spraying and marking the wire rope 21, the spray-shaped marking liquid will spray out from the hollow part, avoiding accumulation inside.

[0055] It also includes an ultrasonic detector 17 connected to the ultrasonic probe, a dry ice cleaning assembly 19 connected to the cleaning nozzle 11, an oiling assembly 20 connected to the oiling nozzle 15, and a marking assembly 18 connected to the marking nozzle 16. It also includes a field controller 25. Each component is connected to the field controller 25 through a control cable 24. The field controller 25 is powered on site by a power supply cable 26. The power supply cable 26 can be the mains power supply on site or a generator configured on site. The field controller 25 operates the operation of each component on the maintenance equipment through the control cable 24. A display screen is provided on the field controller 25. The ultrasonic detector 17 can receive detection information, display the quality inspection information of the wire rope 21 on site. The maintenance operator can send instructions to the marking assembly 18 to form a color mark on the wire rope 21, indicating the approximate location of the quality inspection defect, which is convenient for subsequent further inspection and troubleshooting.

[0056] In this embodiment, component mounting seats 22 are provided on the upper and lower parts of the outer wall of the first housing 1 and on the upper and lower parts of the outer wall of the second housing 2. The component mounting seat 22 includes two opposite mounting seats with mounting holes. The ultrasonic detector 17, the dry ice cleaning assembly 19, the oiling assembly 20, and the marking assembly 18 are respectively fixedly connected to the four component mounting seats 22. Therefore, each component is loaded and fixed on the outer wall of the housing and moves along the wire rope 21 together with the housing. In this embodiment, a housing terminal 23 is installed in the middle of the outer wall of the first housing 1 or the second housing 2. The upper end of the control cable 24 is provided with a cable terminal and is plugged into the housing terminal 23. In this way, when not in use, the control cable 24 can be separated from the main body part of the maintenance equipment, which is convenient for storage and transfer.

[0057] The control cable 24 includes a cable for supplying power to each component and a cable for transmitting signals. The field controller 25 is held by the on-site maintenance personnel and controls the start and stop operation of each component through the field controller 25.

[0058] The ultrasonic detector 17 is connected to the internal ultrasonic probe through a wire harness. Specifically, a wire hole is provided on the side wall of the first housing 1. When the probe base 7 is installed into the first housing 1, the wire harness of its ultrasonic probe passes through the wire hole and is connected to the ultrasonic detector 17. The ultrasonic detector 17 is an existing component and is obtained by purchase, so its structure and function will not be elaborated. A connecting seat is provided on the housing of the ultrasonic detector 17, and the connecting seat is fixedly connected to the component mounting seat 22 on the upper part of the outer wall of the first housing 1 by bolts.

[0059] Please refer to Figure 6 and Figure 10 , it can be seen the structure of the dry ice cleaning component 19 and the installation structure of the cleaning nozzle 11:

[0060] The dry ice cleaning component 19 includes a cleaning base 19-7 with a flow channel inside, a dry ice bucket 19-1 containing dry ice particles inside, and a compressed air tank 19-2. The dry ice bucket 19-1 is detachably connected to the cleaning base 19-7. In this way, before each maintenance work, the dry ice particles are injected into the dry ice bucket 19-1 and installed on the cleaning base 19-7.

[0061] An air supply solenoid valve 19-3 is provided on the side of the cleaning base 19-7, and its inlet is connected to the outlet of the compressed air tank 19-2 through a pipeline. The outlet of the air supply solenoid valve 19-3 is connected to the internal flow channel of the cleaning base 19-7. Compressed air is stored in the compressed air tank 19-2. When the air supply solenoid valve 19-3 is turned on, the compressed air in the compressed air tank 19-2 is injected into the internal flow channel of the cleaning base 19-7 through the pipeline, and the dry ice particles entering the internal flow channel are blown out in a pressurized manner.

[0062] It also includes a cleaning main pipe 19-4 with a plurality of cleaning branch pipes 19-5. The cleaning main pipe 19-4 is connected to the internal flow channel of the cleaning base 19-7, and the cleaning branch pipes 19-5 are connected to the cleaning nozzle 11 through cleaning pipelines 19-6. The compressed air mixed with dry ice particles is discharged from the internal flow channel and then enters the cleaning main pipe 19-4, then enters the cleaning branch pipes 19-5, and then is transported to the cleaning nozzle 11 through the cleaning pipelines 19-6 and is sprayed onto the steel wire rope 21 by the cleaning nozzle 11, achieving the effect of dry ice cleaning. The principle of dry ice cleaning is based on the kinetic energy impact, low-temperature embrittlement effect and sublimation peeling effect of dry ice particles, and the surface dirt of the steel wire rope 21 is efficiently removed by physical means, which will not be elaborated.

[0063] To encapsulate the dry ice cleaning assembly 19, a housing with a cover plate can be configured for it, and the housing is fixedly connected to the assembly mounting base 22 on the upper part of the outer wall of the second housing 2 by bolts. Before performing maintenance activities, open the cover plate on the housing, install the dry ice bucket 19-1 filled with dry ice particles onto the cleaning base 19-7, place the compressed air tank 19-2 inside the housing and connect it to the pipeline. The control action exerted by the on-site controller 25 on the dry ice cleaning assembly 19 refers to controlling the on-off of the air supply solenoid valve 19-3, that is, controlling the on-off of the air path of the compressed air.

[0064] As Figure 6 shown, the cleaning nozzle 11 includes a nozzle body, the root of the nozzle body is fixedly connected to the upper protective cover 12, a notch is provided at the end of the nozzle body, and the steel wire rope 21 is located between the notches. When the first housing 1 and the second housing 2 are closed and locked, the two cleaning nozzles 11 move to both sides of the steel wire rope 21, and the compressed air containing dry ice particles ejected from the cleaning nozzle 11 directly impacts the surface of the steel wire rope 21, achieving the effect of dry ice cleaning. As Figure 1 shown, the cleaning nozzle 11 is located above the brush cleaning assembly 9. When performing maintenance activities, the main body of this maintenance equipment climbs and displaces along the steel wire rope 21 (vertically or with a certain inclination). Therefore, the dry ice cleaning effect is first exerted on the steel wire rope 21, and then the adjacent brush cleaning assembly 9 exerts a further brush cleaning effect. The rationality of this structure is reflected in that during dry ice cleaning, the compressed air containing dry ice particles exerts kinetic energy impact, low-temperature embrittlement effect, and sublimation peeling effect on the steel wire rope 21, and the dirt on its surface is loosened. At this time, directly scraping the surface of the steel wire rope 21 with a steel brush can achieve a better technical effect of promoting the peeling of dirt.

[0065] Please refer to Figure 7 and Figure 11 , it can be seen the structure of the oiling assembly 20 and the installation structure of the oiling nozzle 15:

[0066] The oiling assembly 20 includes an oiling base 20-7 with a flow channel inside, an oil tank 20-1 filled with lubricating grease, and an oil pump 20-2. The oil tank 20-1 is detachably connected to the oiling base 20-7. Before performing maintenance activities, place the appropriate type of lubricating grease into the oil tank 20-1 and install it onto the oiling base 20-7.

[0067] It also includes an oiling main pipe 20-4 with multiple oiling branch pipes 20-5. The inlet of the oiling pump 20-2 is connected to the internal flow channel of the oiling base 20-7, the outlet of the oiling pump 20-2 is connected to the oiling main pipe 20-4, and the oiling branch pipes 20-5 are connected to the oiling nozzles 15 through oiling pipelines 20-6. The oiling pump 20-2 extracts the lubricating grease in the oil tank 20-1 and injects it into the oiling main pipe 20-4. The lubricating grease enters each oiling branch pipe 20-5 from the oiling main pipe 20-4, and then is transported to the oiling nozzles 15 through the oiling pipelines 20-6. The lubricating grease is extruded from the oiling nozzles 15 and smeared on the surface of the wire rope 21.

[0068] To encapsulate the oiling assembly 20, a housing with a cover plate can be configured for it, and the housing is fixedly connected to the assembly mounting seat 22 at the lower part of the outer wall of the second shell 2 by bolts. Before the maintenance activities, open the cover plate on the housing, inject the lubricating grease of the appropriate model into the oil tank 20-1 and install the oil tank 20-1 on the oiling base 20-7. An oiling solenoid valve 20-3 is also installed between the oiling pump 20-2 and the oiling main pipe 20-4. The control action exerted by the on-site controller 25 on the oiling assembly 20 refers to controlling the start and stop of the oiling pump 20-2 and controlling the oiling solenoid valve 20-3. The oiling assembly 20 adopted in the present invention is essentially a lubricating oil pump, and lubricating oil pumps are currently widely used in various mechanical scenarios that require lubrication.

[0069] As Figure 7 shown in, the oiling nozzle 15 includes a nozzle body. The root of the nozzle body is fixedly connected to the lower protective cover 13. A notch is provided at the end of the nozzle body, and the wire rope 21 is located between the notches. When the first shell 1 and the second shell 2 are closed and locked, the two oiling nozzles 15 move to both sides of the wire rope 21, and the lubricating grease extruded from the oiling nozzles 15 is smeared on the surface of the wire rope 21, achieving the effect of oiling maintenance.

[0070] Please refer to Figure 8 and Figure 9 to see the structure of the marking assembly 18 and the installation structure of the marking nozzle 16:

[0071] The marking assembly 18 includes a peristaltic pump 18-1 and a marking liquid bottle 18-3 containing a marking liquid (with colors such as yellow and orange). The extraction pipeline 18-2 connected to the marking liquid bottle 18-3 is connected to the marking nozzle 16 after passing through the peristaltic pump 18-1.

[0072] To encapsulate the marking component 18, a housing with a cover plate can be configured for it, and the housing is fixedly connected to the component mounting seat 22 at the lower part of the outer wall of the first shell 1 by bolts. Before the maintenance activity, the marking liquid is injected into the marking liquid bottle 18-3 and placed into the housing, and the connection with the extraction pipeline 18-2 is established. During operation, the peristaltic pump 18-1 extracts the marking liquid to be colored from the marking liquid bottle 18-3 and pressurizes and conveys it to the marking nozzle 16. The marking nozzle 16 sprays the marking liquid towards the steel wire rope 21 in an atomized form, forming a color marking on the steel wire rope 21. The control action exerted by the on-site controller 25 on the marking component 18 refers to controlling the start and stop of the peristaltic pump 18-1.

[0073] As Figure 8 shown, the root of the marking nozzle 16 is fixedly connected to the lower protective cover 13. When the first shell 1 and the second shell 2 are closed and locked, the marking nozzle 16 moves to the side of the steel wire rope 21.

[0074] The present invention also provides a maintenance method based on the foregoing steel wire rope maintenance equipment, including the following steps:

[0075] Step S1, load the maintenance equipment to the maintenance starting position on the steel wire rope 21 and lock the first shell 1 and the second shell 2, operate the climbing components 5 to act, and the two climbing components clamp the steel wire rope 21 and drive the maintenance equipment to move along the steel wire rope 21 towards the maintenance ending position;

[0076] The maintenance equipment in the present invention is generally applicable to the steel wire rope 21 in a tensioned state, vertically or obliquely arranged. Therefore, the maintenance starting position is usually the lower position on the steel wire rope 21 closer to the ground, and the maintenance ending position is the higher position away from the ground. The maintenance equipment moves between the lower position and the higher position along the steel wire rope 21. Therefore, the control cable 24 should have sufficient length to meet the foregoing maintenance travel.

[0077] Step S2, start the dry ice cleaning component 19 through the on-site controller 25. Compressed air conveys the dry ice particles to the cleaning nozzle 11 and sprays them towards the steel wire rope 21 at high speed, exerting a dry ice cleaning effect on the steel wire rope 21. At the same time, start the brush cleaning component 9 to exert a brush cleaning effect on the steel wire rope 21;

[0078] As described above, the dry ice cleaning effect is first and the brush cleaning effect is second. The two cleaning effects act on the steel wire rope 21 together to clean and strip the dirt on the surface of the steel wire rope 21, making the surface of the steel wire rope 21 clean.

[0079] Step S3, start the oiling component 20 through the on-site controller 25. The lubricating grease is extruded and conveyed to the oiling nozzle 15, and the lubricating grease discharged from the oiling nozzle 15 is applied to the cleaned steel wire rope 21;

[0080] After the lubricating grease is applied to the surface of the wire rope 21, it infiltrates into the interior of the wire rope 21 and will become more and more uniform during the subsequent operation of the wire rope 21.

[0081] Step S4, when reaching the maintenance end position on the wire rope 21, stop the dry ice cleaning assembly 19, the brush cleaning assembly 9 and the oiling assembly 20 through the on-site controller 25 and operate the climbing assembly 5 to reverse and run, and the maintenance equipment moves along the wire rope 21 towards the maintenance start position;

[0082] Step S5, after reaching the maintenance start position, release the lock between the first shell 1 and the second shell 2, remove the maintenance equipment from the wire rope 21, and prepare for the next maintenance.

[0083] In this embodiment, in step S4, during the process of moving back from the maintenance end position towards the maintenance start position, start the ultrasonic detector 17 through the on-site controller 25, and continuously inspect the wire rope 21 through the ultrasonic probe. When the ultrasonic detector 17 indicates a quality inspection defect, start the marking assembly 18, and the colored marking liquid is transported to the marking nozzle 16 and sprayed on the wire rope 21 to form a quality inspection color mark, which is used to indicate the position during the subsequent further defect investigation of the wire rope 21.

[0084] The specific operation method is as follows: The maintenance personnel observe the quality inspection information of the wire rope 21 generated by the ultrasonic detector 17 through the display screen configured by the on-site controller 25. When the quality inspection information indicates a quality inspection defect of internal wire breakage at the current position of the wire rope 21, the maintenance personnel start the peristaltic pump 18-1 of the marking assembly 18 through the on-site controller 25. The peristaltic pump 18-1 pressurizes and transports the marking liquid to the marking nozzle 16, and the atomized marking liquid is sprayed onto the wire rope 21 to form a color mark, which indicates the approximate position of the quality inspection defect. During the subsequent further defect investigation of the wire rope 21, use defect detection facilities (such as large ultrasonic detection facilities) to focus on detecting and investigating the position of the color mark. The investigation range should cover a certain length on both sides of the color mark to avoid missed detection.
