Description

Technical Field

[0001] The utility model belongs to the technical field of steel wire rope lubrication, and particularly relates to automatic lubrication equipment for super-long vertical steel wire ropes. Background Art

[0002] In order to keep the lifting equipment in good operating condition, the operation and maintenance unit needs to carry out regular maintenance. In order to ensure the safe operation of the wire rope, the wire rope on the industrial equipment must be lubricated and maintained regularly. Most of the mainstream wire rope lubrication equipment on the market are equipped with corresponding centralized lubrication devices and creeping lubrication devices. However, the centralized lubrication device of the mainstream wire rope lubrication equipment on the market needs to cooperate with the operation of the wire rope itself, which has limited lubrication time, low efficiency, and low safety; and the creeping lubrication device is only suitable for equipment with a short vertical running distance (such as ordinary gantry cranes) or equipment with sloped wire ropes (such as port machinery and floating cranes) due to the limited driving force of its creeping device. The above-mentioned mainstream wire rope lubrication equipment on the market cannot perfectly adapt to the maintenance of equipment with extra-long vertical wire ropes.

[0003] In summary, most of the current mainstream solutions use fixed installation of lubrication equipment, which is coordinated by wire rope operation. This solution has a greater safety risk and is prone to causing accidents caused by the lubrication equipment. In addition, the fixed installation lubrication method also makes it impossible to reach the end area of ​​the wire rope, resulting in a lubrication dead zone.

[0004] Some fully balanced vertical ship lifts have vertical steel wire ropes on one side that are more than 100 meters long. The lubrication and maintenance of the steel wire ropes has always been a pain point and difficulty for the operation and maintenance units.

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0045] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0046] like Figure 1 As shown, the automatic lubrication equipment for super-long vertical wire ropes in this embodiment includes an autonomous crawling module 1, a lubrication and cleaning module 2 connected to the autonomous crawling module 1, and an integrated vehicle 3 for controlling the actions of the autonomous crawling module 1 and the lubrication and cleaning module 2. The lubrication and cleaning modules 2 are symmetrically provided with two groups at both ends of the autonomous crawling module 1; the autonomous crawling module 1 and the lubrication and cleaning module 2 are connected, and the autonomous crawling module 1 and the lubrication and cleaning module 2 are both clamped on the wire rope; a tensile combination pipeline 32 is connected between the whole composed of the autonomous crawling module 1 and the lubrication and cleaning module 2 and the integrated vehicle 3, and also includes an electric winch 4 for winding the tensile combination pipeline 32.

[0047] The following is a detailed description of the structure and working mode of each module:

[0048] 1. Autonomous crawling module 1:

[0049] like Figure 2 to Figure 4As shown, the function of the autonomous crawling module 1 is to drive the equipment as a whole to crawl automatically along the wire rope. The autonomous crawling module 1 includes a crawling base plate 11, and a crawling cylinder 12 and a solenoid valve 13 are arranged on one side of the upper surface of the crawling base plate 11, and the solenoid valve 13 is electrically connected to the crawling cylinder 12. Clamping crawling units 14 are symmetrically arranged on both sides of the upper surface of the crawling base plate 11, and the clamping crawling units 14 located on the same side as the crawling cylinder 12 are connected to the piston rod of the crawling cylinder 12. The clamping crawling units 14 connected thereto are driven by the crawling cylinder 12, so that the group of clamping crawling units 14 is close to another group of clamping crawling units 14 arranged opposite to it, and the symmetrically arranged clamping crawling units 14 cooperate to achieve the clamping and loosening of the wire rope. The upper surface of the crawling base plate 11 is fixedly provided with an autonomous crawling module slide cover 15 and an autonomous crawling module frame shell 16, which respectively protect the two groups of clamping crawling units 14 on both sides of the upper surface of the crawling base plate 11. The outer sides of the autonomous crawling module slide cover 15 and the autonomous crawling module frame shell 16 are both provided with autonomous crawling module side end handles 17, and the connection between the autonomous crawling module side end handles 17 and the lubrication and cleaning module 2 is achieved.

[0050] Specifically, two groups of the crawling cylinders 12 are provided on one side of the upper surface of the crawling base plate 11, and two groups of clamping crawling units 14 are provided on the same side of the crawling base plate 11. A total of four groups of clamping crawling units 14 are provided on the crawling base plate 11, and the two groups of clamping crawling units 14 close to the crawling cylinders 12 are respectively connected to the piston rods of the two groups of crawling cylinders 12. The clamping crawling unit 14 includes an electric motor 141, a transmission gear set 142 and a power wheel frame 143. The electric motor 141 is fixedly provided on the crawling base plate 11, and the transmission gear set 142 is provided corresponding to the output shaft of the electric motor 141. The power wheel frame 143 is fixedly provided on the crawling base plate 11. Two groups of power wheels 144 are rotatably provided on the power wheel frame 143, and the rotation directions of the two groups of the power wheels 144 are the same. The power wheels 144 are connected to the transmission gear set 142. Under the driving action of the electric motor 141, the power wheel 144 can be driven to rotate through the transmission of the transmission gear set 142, and the rotation of the power wheel 144 can enable the autonomous crawling module 1 to achieve self-help crawling along the wire rope.

[0051] When autonomous crawling module 1 works specifically:

[0052] 1) The autonomous crawling module 1 includes a total of four groups of clamping crawling units 14, of which the two groups of clamping crawling units 14 on the same side are respectively close to the two groups of clamping crawling units 14 on the other side corresponding thereto under the control of the two groups of crawling cylinders 12, and the clamping and loosening of the wire rope by the clamping crawling units 14 is realized through the control of the crawling cylinders 12. At present, in the loosened state, the maximum spacing between the power wheels 144 is 80mm, and the diameter range of the wire rope that can be adapted during normal use is 60 to 80mm. When in the clamped state with the wire rope, the contact length between the power wheel 144 and the wire rope is 330mm. The longer contact area makes the overall operation of the robot more stable and reliable when the robot is in the clamped state with the wire rope and in the powered crawling state of the robot.

[0053] 2) When the power wheels 144 on both sides of the crawling base 11 clamp the wire rope, the four groups of electric motors 141 of the clamping crawling units 14 work together to drive the power wheels 144 to rotate in the corresponding opposite direction through the drive transmission of the transmission gear set 142, thereby controlling the forward and backward movement of the autonomous crawling module 1 on the wire rope. The crawling speed of the robot on the wire rope is controlled by a synchronous motor, with a maximum climbing speed of 10m / min and a maximum descending speed of 15m / min.

[0054] 3) The autonomous crawling module 1 in this solution has a small size and a large load capacity, with a total weight of 16kg and a load capacity of up to 120kg. It also has a synchronous auxiliary pipeline winding unit to achieve synchronous winding or release of a 130-meter combined pipeline during the robot's crawling process.

[0055] 4) The overall design of the autonomous crawling module 1 in this solution is modular, which enables two or more robots to perform lubrication operations simultaneously and improves lubrication efficiency. Both the hardware structure design and the software program control function are modular, which facilitates the input and output of each hardware device and functional module of the robot, and realizes the input and output of each corresponding adaptive software control function.

[0056] 5) The autonomous crawling module 1 in this solution can be used as a carrying platform, and can carry standardized oiling modules or other operating modules (such as wire rope flaw detection, camera, etc.) in both directions along the wire rope to achieve bidirectional lubrication in the vertical direction of the wire rope without being restricted by the lubrication direction.

[0057] 2. Lubrication and cleaning module 2:

[0058] like Figure 2 to Figure 8As shown, the function of the lubrication and cleaning module 2 is to remove oil and apply oil to the surface of the wire rope. The lubrication and cleaning module 2 includes a lubrication and cleaning module side handle 21, and the lubrication and cleaning module 2 is connected to the autonomous crawling module side handle 17 through the lubrication and cleaning module side handle 21. The lubrication and cleaning module 2 is mounted on the autonomous crawling module 1 to realize the function of automatic cleaning, lubrication and maintenance of the wire rope.

[0059] The lubrication cleaning module 2 also includes a lubrication base plate 22, and a lubrication cylinder 23 is symmetrically arranged on the upper surface of the lubrication base plate 22, and a degreasing lubrication unit 24 is symmetrically arranged on the piston rod of the lubrication cylinder 23. The lubrication cylinders 23 on both sides respectively drive the corresponding degreasing lubrication units 24 to approach the wire rope from both sides to degreasing and lubricating the wire rope. The upper surface of the lubrication base plate 22 is also provided with a lubrication cleaning module slide cover 25 and a lubrication cleaning module frame shell 26, and the lubrication cleaning module slide cover 25 and the lubrication cleaning module frame shell 26 respectively protect the degreasing lubrication units 24 on both sides.

[0060] Specifically, at least two groups of the lubricating cylinders 23 are provided on the same side of the lubricating bottom plate 22 . The cooperation of two or more groups of lubricating cylinders 23 can better ensure the driving stability of the degreasing and lubricating unit 24 .

[0061] Specifically, the degreasing and lubricating unit 24 includes a clean oiling nylon block 241, and a degreasing structure 242 is provided on the side of the clean oiling nylon block 241 away from the autonomous crawling module 1. The inner diameter of the two groups of correspondingly arranged clean oiling nylon blocks 241 is slightly larger than the diameter of the steel wire to be maintained, ensuring that when the clean oiling nylon block 241 is closed, the extrusion force of the lubricating cylinder 23 can be transmitted to the degreasing structure 242 of the clean oiling nylon block 241, and the old oil on the steel wire rope can be scraped off by the degreasing structure 242. A scouring pad installation slot 243 is provided at the end of the degreasing structure 242. After the scouring pad is installed in the scouring pad installation slot 243, the scouring pad can further remove the old oil between the strands of the steel wire rope to be cleaned of the old oil.

[0062] The back of the clean oil-filled nylon block 241 is provided with a cylinder push structure mounting notch 244, and the clean oil-filled nylon block 241 is connected to the lubricating cylinder 23 through the cylinder push structure mounting notch 244. The back of the clean oil-filled nylon block 241 is also provided with a clean oil-filled oil passage 245, and an oil-filled channel 246 is opened in the clean oil-filled nylon block 241. An oil-path processing hole is opened on the top wall of the clean oil-filled nylon block 241, and after the oil-filled channel 246 is opened, the oil-path processing hole is blocked. The clean oil-filled oil passage 245 is connected with the oil-filled channel 246, and a lubrication cavity 247 is provided in the middle of the inner side of the clean oil-filled nylon block 241, and a lubrication cavity oil outlet 248 is opened on the inner side of the lubrication cavity 247. Preferably, four lubrication cavity oil outlets 248 are provided, and the steel wire rope can be lubricated by oil discharge through the lubrication cavity oil outlets 248. The clean oil filling oil passage 245 is arranged corresponding to the central position of the height of the four lubrication cavity oil outlets 248. This structural arrangement can ensure that the oil discharge amount of the four lubrication cavity oil outlets 248 is consistent, so that the lubrication of the entire steel wire rope cross section is uniform, and the grease flowing out spreads everywhere and fills the lubrication cavity 247. Two groups of spring tiles 249 higher than the lubrication cavity 247 are arranged on the inner side of the clean oil filling nylon block 241. The two groups of spring tiles 249 are symmetrically arranged on both sides of the lubrication cavity 247, and a spring with a stroke of 10 mm is installed on the rear side of the spring tile 249. The spring makes the spring tile 249 fit tightly on the steel wire rope, and a relatively closed lubrication cavity 247 is formed by the arrangement of the two groups of spring tiles 249. The lubrication cavity 247 is filled with lubricating grease, so that the steel wire rope is thoroughly infiltrated with grease.

[0063] Furthermore, in order to prevent grease from overflowing from the side seam of the spring tile 249 structure, a silicone anti-overflow gasket sticking groove 2410 is provided on one side of the spring tile 249 away from the lubrication cavity 247, and a silicone anti-overflow gasket is installed in the silicone anti-overflow gasket sticking groove 2410 to prevent grease from overflowing.

[0064] Furthermore, a sponge installation groove 2411 is provided at one end of the clean oil-filled nylon block 241 away from the oil removal structure 242. Since different greases have different dynamic viscosities, some greases have very low dynamic viscosities and their overall state is very thin, similar to that of water. At this time, a specially customized sponge needs to be installed at the sponge installation groove 2411 structure according to the state of the grease to absorb excess flowing grease and prevent the flowing grease from dripping and polluting the environment.

[0065] When the lubrication and cleaning module 2 works specifically:

[0066] 1) Select a suitable lubrication and cleaning module 2 according to the size of the wire rope, install the lubrication and cleaning module 2 on the autonomous crawling module 1, and drive the cleaning oil-filled nylon block 241 to approach and fit the outer surface of the wire rope through the lubrication cylinder 23. During the operation of the autonomous crawling module 1, the oil removal structure 242 that matches the wire rope texture can scrape off the old grease on the surface of the wire rope, and collect and recycle it by a special recycling device.

[0067] 2) Oil is injected into the lubrication cavity 247 through the designed clean oil injection oil passage 245, oil injection channel 246, and lubrication cavity oil outlet 248, and the steel wire rope is oiled under the action of the spring tile 249 and the silicone anti-overflow gasket. Each clean oil injection nylon block 241 is opened and closed by two lubrication cylinders 23, and each path is opened and closed by the solenoid valve 13.

[0068] 3) The injected lubricating oil can be heated and pressurized to the optimal penetration condition through an external high-pressure oil injection and temperature control unit. The grease is evenly coated 360° on the wire rope and the strand seam through the oil injection module, forming an oil film with a uniform thickness of 0.5 to 1 mm on the surface.

[0069] 4) In this module, two groups of lubrication and cleaning modules 2 (lubrication and cleaning module 2 at the upper end and lubrication and cleaning module 2 at the lower end) are symmetrically arranged at both ends of the autonomous crawling module 1. When the lubrication and cleaning module 2 moves up and down with the autonomous crawling module 1, the effects of cleaning, degreasing and lubricating can be achieved. During the downward process, the lubrication and cleaning module 2 at the lower end is degreasing, and the lubrication and cleaning module 2 at the upper end is oiling. During the upward process, the lubrication and cleaning module 2 at the upper end is degreasing, and the lubrication and cleaning module 2 at the lower end is oiling. By controlling the upper and lower groups of degreasing systems and oiling systems respectively, bidirectional lubrication and cleaning in the vertical direction of the wire rope can be achieved without being restricted by the lubrication direction.

[0070] 3. Integrated vehicle 3 and electric winch 4:

[0071] like Figure 1 , Figures 9 to 11 As shown, the function of the integrated vehicle 3 is to control the actions of the autonomous crawling module 1 and the lubricating and cleaning module 2. The integrated vehicle 3 includes a general control unit 34, a lubricating grease structure unit 33, a tensile combination pipeline 32 and an integrated vehicle sheet metal frame unit 31. The general control unit 34 is arranged on the integrated vehicle sheet metal frame unit 31, and the general control unit 34 is electrically connected to the lubricating grease structure unit 33 and the tensile combination pipeline 32, and the general control unit 34 is connected to the autonomous crawling module 1 and the lubricating and cleaning module 2 through the tensile combination pipeline 32, and the lubricating grease structure unit 33 is connected to the lubricating and cleaning module 2 through the tensile combination pipeline 32.

[0072] The integrated vehicle sheet metal frame unit 31 includes an integrated vehicle sheet metal frame 311 . The integrated vehicle sheet metal frame 311 adopts a sheet metal structure. A Formica wheel 312 is provided on the bottom wall of the integrated vehicle sheet metal frame 311 . The total control unit 34 is installed on the integrated vehicle sheet metal frame 311 .

[0073] The electric winch 4 is arranged on the integrated vehicle sheet metal frame 311, and the anti-tensile combined pipeline 32 is provided with signal lines, air pipes, cables and oil pipes inside, and is made of anti-tensile mesh wire woven, wrapped and rubber-coated. The free end of the anti-tensile combined pipeline 32 is provided with an oil-gas-electric quick connector, and the anti-tensile combined pipeline 32 is connected to the oil-gas-electric quick connector of the autonomous crawling module 1 and the lubrication and cleaning module 2 through the oil-gas-electric quick connector, and the anti-tensile combined pipeline 32 is orderly wound around the electric winch 4.

[0074] like Fig.15 As shown, the electric winch 4 is composed of a winch base 41, an electric winch 42, a cable arranger 43, and a servo motor. The servo motor drives the electric winch to retract and release the tensile combined pipeline 32, and the cable arranger 43 evenly reels the tensile combined pipeline 32 on the electric winch 42. The electric winch also includes an oil-gas-electric high-voltage sealing slip ring device. Since the signal line, air pipe, cable, and oil pipe inside the pipeline are all connected to the autonomous crawling module 1 and the lubrication and cleaning module 2 at one end, and the other end is reeled on the electric winch, the pipelines will be tangled in disorder during the pipeline retraction process. For this reason, the design adds an oil-gas-electric high-voltage sealing slip ring device, which is installed at the axis of the roller of the synchronous retraction unit. Its own 600kg pressure seal can meet the needs of the fixed end of the signal line, air pipe, cable, and oil pipe. At the same time, when the synchronous retraction unit retracts and releases the pipeline, it can rotate with the rotation of the roller to avoid the phenomenon of disordered entanglement of the signal line, air pipe, cable, and oil pipe when the pipeline is retracted and released. A set of absolute encoders is respectively arranged at the autonomous crawling module 1 and the cable arranger 43. The absolute encoder at the autonomous crawling module 1 collects the walking speed of the autonomous crawling module 1 and feeds it back to the processor of the general control unit 34. The processor sends the execution command to the hoist servo motor to drive the electric winch 42 of the hoist to reel in and release the wire to follow the walking of the autonomous crawling module 1. In addition, the absolute encoder at the cable arranger 42 feeds back the reeling and releasing speed to the general control unit 34. The general control unit 34 controls the hoist servo motor as a whole according to the speed collected by the absolute encoder at the cable arranger 42, so as to realize the synchronous operation of the electric hoist 4 and the autonomous crawling module 1.

[0075] In this solution, the length of the tensile combined pipeline 32 is not less than 130m, and a set of absolute encoders are respectively provided at the autonomous crawling module 1 and the cable arranger 42, with a weight of about 60kg and a tensile strength of 10000N.

The heating temperature of the heating belt can be controlled by the temperature controller 337, thereby ensuring that the grease in the oil storage barrel 331 is heated and the grease is in a flowing state. The inner middle part of the inner layer 335 of the oil storage barrel is provided with an oil storage barrel lining plate, which is a flange structure 338. The top of the oil filling pump 332 is fixedly connected to the oil storage barrel lining plate by screws. The top of the oil filling pump 332 is provided with a rotatable fan blade for stirring the grease in the barrel so that the grease is quickly and evenly heated. An oil outlet tee 339 is provided on the outer layer 336 of the oil storage barrel. One end of the oil outlet tee 339 passes through the outer layer 336 of the oil storage barrel and the inner layer 335 of the oil storage barrel, extends into the oil storage barrel 331 and is connected to the oil outlet of the oil injection pump 332. An oil outlet pipe 3310 is connected to the oil outlet tee 339 of the oil storage barrel. An oil outlet pressure gauge 3311 is provided on the oil outlet pipe 3310. The oil outlet speed is sensed by the reading of the oil outlet pressure gauge 3311, and the oil output is controlled by adjusting the speed of the oil injection machine or adjusting the creeping speed of the equipment according to the oil injection pressure.

[0077] During operation, the integrated vehicle sheet metal frame unit 31 equipped with the lubricating grease structure unit 33 is located on the platform of the top wire rope electric winch 4.

[0079] When the integrated vehicle 3 and the electric winch 4 are working:

[0080] The lubricating grease structural unit 33 provides fluid grease with uniform temperature, and is transported to the lubricating and cleaning module 2 through the tensile combined pipeline 32 to lubricate the steel wire rope. At the same time, through the connection of the tensile combined pipeline 32, the operation of the autonomous crawling module 1 and the lubricating and cleaning module 2 can be controlled by the main control unit 34.

[0081] 4. Connection between the side handle 17 of the autonomous crawling module and the side handle 21 of the lubrication and cleaning module:

[0082] like Figure 12 to Figure 14As shown, the autonomous crawling module 1 and the lubricating and cleaning module 2 are connected through the autonomous crawling module side handle 17 and the lubricating and cleaning module side handle 21, and the autonomous crawling module side handle 17 and the lubricating and cleaning module side handle 21 are specifically connected through a spring pin 41 and a handle fastening sleeve 42. The inner wall of the handle fastening sleeve 42 is provided with an internal thread, the two ends of the autonomous crawling module side handle 17 are stainless steel rod-shaped structures, and the outer surface of the autonomous crawling module side handle 17 near the end position is provided with an external thread, the lubricating and cleaning module side handle 21 is composed of stainless steel pipes, and the outer surface of one end of the lubricating and cleaning module side handle 21 is provided with an external thread, the stainless steel rod end of the autonomous crawling module side handle 17 is inserted into the lubricating and cleaning module side handle 21, and the handle fastening sleeve 42 is provided at the connection between the autonomous crawling module side handle 17 and the lubricating and cleaning module side handle 21 through a threaded sleeve, and a through hole for installing the spring pin 41 is opened on the autonomous crawling module side handle 17, and the spring pin 41 is a standard part.

[0083] When used specifically:

[0084] When the lubrication and cleaning module 2 is mounted and used together with the autonomous crawling module 1, the rod end of the autonomous crawling module side handle 17 is inserted into the stainless steel tube of the lubrication and cleaning module side handle 21, and then the spring pin 41 on the autonomous crawling module side handle 17 is pulled out, and the handle fastening sleeve 42 is screwed toward the end of the lubrication and cleaning module side handle 21, so that the internal thread of the handle fastening sleeve 42 is screwed together with the external thread of the stainless steel tube of the lubrication and cleaning module side handle 21 and the external thread of the rod structure of the autonomous crawling module side handle 17, and then the spring pin 41 is inserted into the hole of the autonomous crawling module side handle 17 to realize the connection between the autonomous crawling module side handle 17 and the lubrication and cleaning module side handle 21.

[0085] The advantages of the above structure are: taking into account the particularity of the robot's use and working environment, it is necessary to conveniently operate the loading / disassembly of the module, so the two relatively heavy modules are connected in a more ideal way through this handle fixing method, so that even if resonance occurs during use, the handle connection will not loosen, and the frequent use of loading / disassembly of the module will not cause the structure to wear and fail.

[0086] At the same time, this embodiment also provides a method for using an ultra-long vertical steel wire rope automatic lubrication device, which specifically includes the following steps:

[0087] 1) The general control unit 34 controls the operation of the autonomous crawling module 1 and the lubrication and cleaning module 2. On the one hand, the general control unit 34 controls the action of the autonomous crawling module 1 through the connection of the anti-tensile combination pipeline 32. On the other hand, the general control unit 34 controls the lubricating grease structure unit 33 to provide fluid grease with uniform temperature to the lubrication and cleaning module 2, and transports it to the lubrication and cleaning module 2 through the anti-tensile combination pipeline 32 to lubricate the wire rope.

[0088] 2) The autonomous crawling module 1 includes a total of four groups of clamping crawling units 14, of which two groups of clamping crawling units 14 on the same side are respectively close to the two groups of clamping crawling units 14 on the other side under the control of the two groups of crawling cylinders 12, and the clamping and loosening of the wire rope by the clamping crawling units 14 is realized through the control of the crawling cylinders 12. When the power wheels 144 on both sides of the crawling base 11 clamp the wire rope, the power wheels 144 are driven to rotate in the corresponding opposite direction through the forward and reverse rotation of the electric motors 141 of the four groups of clamping crawling units 14, and the driving transmission of the transmission gear set 142, thereby controlling the autonomous crawling module 1 to move forward and backward on the wire rope.

[0089] 3) The lubricating and cleaning module 2 is mounted on the autonomous crawling module 1 by connecting the autonomous crawling module side handle 17 with the lubricating and cleaning module side handle 21 , and the movement of the autonomous crawling module 1 drives the lubricating and cleaning module 2 to move along the wire rope.

[0090] 4) The lubricating cylinder 23 drives the cleaning oiling nylon block 241 to approach and fit the outer surface of the wire rope. During the operation of the autonomous crawling module 1, the oil removal structure 242 that matches the wire rope texture can scrape off the old grease on the surface of the wire rope, and collect and recycle it by a special recovery device. And the oil injection pump 332 is used to inject oil into the lubrication cavity 247 along the tensile combined pipeline 32 to the designed cleaning oil injection oil passage 245, the oil injection channel 246, and the lubrication cavity oil outlet 248, and the wire rope is oiled under the action of the spring tile 249 and the silicone anti-overflow gasket. By symmetrically arranging two groups of lubricating and cleaning modules 2 at both ends of the autonomous crawling module 1, the lubricating and cleaning modules 2 can achieve the effects of cleaning, degreasing and lubricating when they go up and down with the autonomous crawling module 1; during the down process, the lower end lubricating and cleaning module 2 is degreasing, and the upper end lubricating and cleaning module 2 is oiling; during the up process, the upper end lubricating and cleaning module 2 is degreasing, and the lower end lubricating and cleaning module 2 is oiling. By controlling the upper and lower oil removal systems and oil coating systems respectively, bidirectional lubrication and cleaning of the wire rope in the vertical direction can be achieved without being restricted by the lubrication direction.

[0091] 5) During the movement of the autonomous crawling module 1 and the lubricating and cleaning module 2 , the electric winch 4 is used to retract and release the tensile assembly pipeline 32 to adapt to the movement of the autonomous crawling module 1 and the lubricating and cleaning module 2 .

[0092] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
