An adsorption-type wire rope inspection robot

Abstract

This invention belongs to the field of inspection robot technology and discloses an adsorption-type steel wire rope inspection robot, including a base, an inspection camera, a steel wire rope, and a walking mechanism. Two marking rings are fixedly installed on the top of the base. Three fixed cylinders distributed at equal angles are fixedly sleeved inside the marking rings. A telescopic rod is fixedly connected to the inner end of each fixed cylinder, and a marking wheel is movably connected through the telescopic rod. The inside of each fixed cylinder is sealed with rust-preventive liquid and a connecting post. This invention uses a second spring to move the connecting post outwards (the outward end refers to the direction the opening of the fixed cylinder points), thereby misaligning the connecting groove with the sealing block. This allows the dye to automatically seep into the second outlet groove along the connecting groove, and then be applied to the outer surface of the marking wheel through a contact block. This automatically marks the area near the corrosion zone on the outer surface of the steel wire rope, thus achieving a highly efficient automatic marking function.

Description

Technical Field

[0001] The invention belongs to the technical field of inspection robots, and in particular relates to an adsorption-type wire rope inspection robot. Background Art

[0002] The adsorption-type wire rope inspection robot is mainly used to conduct patrol inspections on high-altitude wire ropes used in bridges and other buildings, and to automatically inspect the outer surface of the wire rope for defects, thereby saving labor costs and improving inspection efficiency.

[0003] At present, the existing adsorption-type wire rope inspection robots mainly rely on cameras to perform mechanical visual inspections on the outer surface of the wire rope when working. Although they replace manpower, they are unable to automatically mark the corrosion defects of the wire rope when they are detected. The existing wire rope inspection robots are too dependent on the inspection function of electronic equipment and are unable to automatically mark the defective parts, which brings great trouble to subsequent maintenance.

[0004] At the same time, since the wire rope is exposed to sunlight for a long time, the bottom of its outer surface is basically not exposed to light. On rainy days, water will slide to its bottom under the action of gravity. The lack of sunlight exposure and evaporation will aggravate the corrosion of the bottom of the outer surface of the wire rope, thereby causing the corrosion cycle of the upper and lower parts of the outer surface of the steel wire to deviate. The existing inspection robots do not have active control functions. Simply adding inspection cameras will inevitably increase the cost of use, and may even cause the overall force imbalance of the robot and cause it to roll over.

[0005] Therefore, the present invention is devoted to designing a wire rope inspection robot which can automatically mark, has an active synchronous wire rope corrosion cycle function and has high stability. Summary of the invention

[0006] The purpose of the present invention is to provide an adsorption-type wire rope inspection robot to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: an adsorption-type wire rope inspection robot, comprising a base, a detection camera, a wire rope and a walking mechanism, wherein two marking rings are fixedly installed on the top of the base, and three fixed cylinders distributed at equal angles are fixedly sleeved inside the marking rings, and the inner side end of the fixed cylinder is fixedly connected with a telescopic rod and is movably connected with a marking wheel through the telescopic rod, the internal sealing sleeve of the fixed cylinder is connected with an anti-rust liquid and a sleeve column, the outer surface of the sleeve column is movably sleeved with a No. 2 spring and a connecting groove is provided, the internal movably sleeved with a No. 1 spring, the interior of the fixed cylinder is filled with a sealing plate and a dye, and a No. 1 liquid outlet groove and a No. 2 liquid outlet groove are respectively provided on the left and right sides of the interior of the fixed cylinder, the inner wall of the fixed cylinder is fixedly connected with a sealing block, the other end of the sleeve column is fixedly connected with a contact block, and a sponge block is movably installed inside the contact block;

[0008] When the device is working, the robot is inserted along the initial end of the steel wire rope, so that the marking wheel contacts the steel wire rope and drives the telescopic rod to shrink by applying pressure, driving the sleeve column to move toward the inner direction of the fixed cylinder, so that the No. 1 spring and the No. 2 spring are stretched, and the sealing block blocks the connecting groove. The walking mechanism and the detection camera are started, driving the base and the marking ring to move along the axial direction of the steel wire rope, and the detection camera in operation observes and detects the outer surface of the steel wire rope;

[0009] During the robot's movement, the marking wheel and the outer surface of the wire rope slide relative to each other. At this time, the compressed No. 1 spring presses the anti-rust liquid, driving the sealing plate to enter the inner cavity of the contact block along the No. 2 liquid outlet groove, and then gradually immerse into the sponge block, and finally smear it on the outer surface of the marking wheel through the outer end opening of the contact block, so that the rotating marking wheel evenly smears the sealing plate on the outer surface of the wire rope;

[0010] By arranging a marking wheel to be in close contact with the outer surface of the steel wire rope during operation, during the movement of the robot, the anti-rust liquid is pressurized by the compressed No. 1 spring, driving the sealing plate to penetrate into the inner cavity of the contact block along the No. 1 liquid outlet groove, so that the sealing plate is gradually immersed in the dye, and then gradually smeared on the outer surface of the marking wheel through the opening of the contact block, so that the marking wheel can omni-directionally smear the outer surface of the steel wire rope during the rotation process, thereby focusing on increasing the anti-rust and anti-corrosion function of the bottom of the outer surface of the steel wire rope, and more sealing plates are distributed at the bottom of the outer surface of the steel wire rope through the fluidity of the sealing plate and the action of gravity, thereby compensating for the excessive corrosion of the bottom of the outer surface of the steel wire rope, thereby synchronizing the corrosion cycle of each area of ​​the outer surface of the steel wire rope and reducing maintenance costs.

[0011] When the marking wheel contacts the defective part of the wire rope, the gap on the outer surface of the wire rope increases due to corrosion, and the marking wheel loses its limit support. At the same time, the No. 2 spring drives the sleeve column to move outward, so that the connecting groove and the sealing block are gradually staggered. The dye inside the fixed cylinder leaks into the No. 2 liquid outlet tank along the connecting groove, and is smeared on the outer surface of the marking wheel through the contact block. The rotating marking wheel drives the dye outward and automatically smears it on the position near the corrosion area on the outer surface of the wire rope to complete the automatic marking. When the marking wheel moves to the normal area on the outer surface of the wire rope, it drives the telescopic rod and the sleeve column to reset, so that the sealing block automatically re-blocks the connecting groove, and the dye no longer leaks outward.

[0012] The marking wheel is sleeved on the outer surface of the steel wire rope in a staggered manner at equal angles by providing a marking ring and a fixing cylinder, the marking wheel is movably connected to the outer end of the fixing cylinder by providing a telescopic rod, and the sleeve column and the contact block are driven by a No. 2 spring to apply pressure to the marking wheel, so that during the movement, the sleeve column drives the marking wheel to apply pressure and contact the outer surface of the steel wire rope, and when encountering a corrosion area on the outer surface of the steel wire rope, the gap caused by the corrosion is used to make the marking wheel sink into it, and then the sleeve column is driven by the No. 2 spring to move to the outer end (the outer end refers to the direction in which the opening of the fixing cylinder points), so that the connecting groove and the sealing block are staggered, so that the dye automatically penetrates into the No. 2 liquid outlet groove along the connecting groove, and then is smeared on the outer surface of the marking wheel through the contact block, and then the vicinity of the corrosion area on the outer surface of the steel wire rope is automatically marked, thereby realizing an efficient automatic marking function.

[0013] Preferably, the walking mechanism comprises a connecting frame, two bearings distributed on the left and right are fixedly installed on the top of the inner wall of the connecting frame, a connecting shaft that passes through the top of the connecting frame is fixedly sleeved inside the bearing, a walking wheel is fixedly connected to the top of the connecting shaft, a gear is fixedly sleeved on the outer surface of the connecting shaft, a motor is fixedly installed on the bottom of the inner wall of the connecting frame, the output shaft of the motor is fixedly connected to the connecting shaft on the right, and the two walking wheels are movably sleeved on the outer surface of the wire rope;

[0014] Start the connection frame and drive the connection shaft and the travel wheel to rotate. Under the transmission action of the gears, the two travel wheels rotate synchronously towards each other, thereby moving on the outer surface of the wire rope, driving the base to move, and thus cooperating with the detection camera to perform inspection operations.

[0015] Preferably, the two ends of the No. 1 spring are elastically connected to the rust-proof liquid and the inner wall of the sleeve column respectively, the No. 1 spring is in a compressed state during operation, and the sealing plate is located between the sleeve column and the rust-proof liquid;

[0016] During operation, the two marking rings are sleeved on the outer surface of the wire rope, so that the marking wheel is in close contact with the outer surface of the wire rope and relatively pressurized, driving the contact block and the sleeve column to move toward the inner direction of the fixed cylinder. At this time, the No. 1 spring is compressed, thereby pressurizing the anti-rust liquid during the subsequent movement, and then pushing the sealing plate toward the contact block, thereby realizing the automatic application function.

[0017] Preferably, the dye is sealed and filled between the outer surface of the sleeve column and the inner wall of the fixed cylinder, the sealing block is in sealing contact with the outer surface of the sleeve column and the height of the contact part is greater than the height of the connecting groove;

[0018] When the fixed cylinder is sleeved on the outer surface of the wire rope, the pressure between the marking wheel and the wire rope drives the sleeve column to move toward the inside of the fixed cylinder until the sealing block just blocks the position of the connecting groove. Only when the marking wheel moves to the defective area of ​​the corroded outer surface of the wire rope, the marking wheel that loses its support will move toward the defective area of ​​the wire rope driven by the No. 2 spring, driving the sleeve column to move toward the outside of the fixed cylinder, thereby staggering the connecting groove and the sealing block, allowing the dye to seep out along the connecting groove and complete automatic marking.

[0019] Preferably, the No. 1 liquid outlet groove and the No. 2 liquid outlet groove are respectively connected to the inner cavity of the contact block, the No. 1 liquid outlet groove is a through-type design, and the No. 2 spring is filled in the No. 1 liquid outlet groove;

[0020] The interior of the socket column is provided with a No. 1 liquid outlet groove and a No. 2 liquid outlet groove which are isolated from each other, which can ensure that the No. 1 liquid outlet groove and the dye will not interfere with each other during operation. The sealing plate can be immersed in the dye along the No. 1 liquid outlet groove under the action of the No. 1 spring and the anti-rust liquid, and then complete the automatic coating protection function through the opening of the contact block.

[0021] Preferably, a rubber layer is movably sleeved on the outer surface of the marking wheel and is in limited contact with one end of the outer side of the contact block, and the marking wheel is in pressure contact with the steel wire rope through the external rubber layer;

[0022] The rubber layer added to the outer surface of the marking wheel can be in close contact with the marking wheel, which can reduce the wear of the wire rope and reduce maintenance costs. At the same time, the marking wheel that is deformed by pressure will automatically apply the No. 1 liquid outlet groove and the dye from the inside of the fixed cylinder in the form of seal-seal release-seal through mutual contact with the contact block, avoiding waste of the sealing plate during the application process.

[0023] Preferably, the two marking rings are symmetrically distributed on the front and rear sides of the detection camera, the number of the fixing tubes is six and evenly divided into two groups, the two groups of fixing tubes are respectively located inside the two marking rings, and the axial deviation angle of the two groups of fixing tubes around the wire rope is 60°;

[0024] The stability of the base during operation is increased by providing two sets of interlaced marking rings and fixed cylinders, and the marking wheel is movably connected to the fixed cylinder through a telescopic rod, so that the marking wheel can flexibly move along the axial direction of the fixed cylinder, and the marking wheel is stably supported by the cooperation of the No. 2 spring, the sleeve column and the contact block, so that the marking wheel is stably supported on the outer surface of the wire rope, and the stability of the base during movement is greatly increased by cooperating with the marking ring.

[0025] Preferably, the interior of the contact block is divided into two independent cavities which are respectively connected to the second liquid outlet groove and the first liquid outlet groove, and the sponge block is filled in the left cavity inside the contact block;

[0026] The two independent cavities inside the contact block are connected to the No. 1 liquid outlet groove and the No. 2 liquid outlet groove respectively, so as to avoid the mutual influence between the No. 1 liquid outlet groove and the No. 2 liquid outlet groove. The sponge block absorbs the sealing plate to avoid the sealing plate from leaking too fast, thereby playing a slow release role.

[0027] Preferably, the two ends of the second spring are elastically connected to the fixing tube and the sleeve column respectively, and the second spring is in a stretched state when working;

[0028] The No. 2 spring is in a stretched state during operation. When the marking ring is sleeved on the outer surface of the wire rope through the marking wheel, the marking wheel is pressed by the wire rope, thereby driving the contact block and the sleeve column to move toward the inner direction of the fixed tube, thereby compressing the No. 2 spring. This provides movement conditions for the subsequent marking wheel when encountering local depressions caused by corrosion on the outer surface of the wire rope, so that the stretched No. 2 spring uses its rebound force to drive the sleeve column to move, causing the connecting groove and the sealing block to stagger, allowing the dye to automatically seep out and completing automatic marking.

[0029] The beneficial effects of the present invention are as follows:

[0030] 1. The present invention sleeves the marking wheel on the outer surface of the steel wire rope in a staggered manner at equal angles, and movably connects the marking wheel to the outer end of the fixing cylinder by providing a telescopic rod. The sleeve column and the contact block are driven by a No. 2 spring to apply pressure to the marking wheel, so that during the movement, the sleeve column drives the marking wheel to apply pressure and contact the outer surface of the steel wire rope. When encountering a corrosion area on the outer surface of the steel wire rope, the gap generated by the corrosion is used to make the marking wheel sink into it, and then the sleeve column is driven by the No. 2 spring to move toward the outer end (the outer end refers to the direction in which the opening of the fixing cylinder points), so that the connecting groove and the sealing block are staggered, so that the dye automatically penetrates into the No. 2 liquid outlet groove along the connecting groove, and then is smeared on the outer surface of the marking wheel through the contact block, and then the vicinity of the corrosion area on the outer surface of the steel wire rope is automatically marked, thereby realizing a high-efficiency automatic marking function.

[0031] 2. The present invention provides a marking wheel which is in close contact with the outer surface of the steel wire rope during operation. During the movement of the robot, the compressed No. 1 spring applies pressure to the anti-rust liquid, driving the sealing plate to penetrate into the inner cavity of the contact block along the No. 1 liquid outlet groove, so that the sealing plate is gradually immersed in the dye, and then gradually smeared on the outer surface of the marking wheel through the opening of the contact block, so that the marking wheel can omni-directionally smear the outer surface of the steel wire rope during rotation, thereby focusing on increasing the anti-rust and anti-corrosion function of the bottom of the outer surface of the steel wire rope, and more sealing plates are distributed to the bottom of the outer surface of the steel wire rope through the fluidity of the sealing plate and the action of gravity, thereby compensating for the excessive corrosion of the bottom of the outer surface of the steel wire rope, thereby synchronizing the corrosion cycle of each area of ​​the outer surface of the steel wire rope and reducing maintenance costs.

[0032] 3. The present invention increases the stability of the base during operation by providing two groups of mutually staggered marking rings and fixed cylinders, and by providing a fixed cylinder movably connected to a marking wheel through a telescopic rod, the marking wheel can be flexibly moved along the axial direction of the fixed cylinder, and the marking wheel is stably supported by the cooperation of the No. 2 spring, the sleeve column and the contact block, so that the marking wheel is stably supported on the outer surface of the wire rope, and the stability of the base during movement is greatly increased by cooperating with the marking ring.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] like Figures 1 to 9 As shown, in the embodiment of the present invention, an adsorption-type wire rope inspection robot includes a base 1, a detection camera 2, a wire rope 5 and a walking mechanism 6, two marking rings 3 are fixedly installed on the top of the base 1, and three fixed cylinders 4 with equal angles are fixedly sleeved inside the marking ring 3, and the inner side end of the fixed cylinder 4 is fixedly connected with a telescopic rod 7 and is movably connected with a marking wheel 8 through the telescopic rod 7, and the inner sealing sleeve of the fixed cylinder 4 is connected with an anti-rust liquid 14 and a sleeve column 9, and the outer surface of the sleeve column 9 is movably sleeved with a No. 2 spring 16 and a connecting groove 17 is provided, and the inner surface of the fixed cylinder 4 is movably sleeved with a No. 1 spring 15, and the interior of the fixed cylinder 4 is filled with a sealing plate 13 and a dye 20, and the left and right sides of the interior of the fixed cylinder 4 are respectively provided with a No. 1 liquid outlet trough 11 and a No. 2 liquid outlet trough 12, and the inner wall of the fixed cylinder 4 is fixedly connected with a sealing block 18, and the other end of the sleeve column 9 is fixedly connected with a contact block 10, and the contact block 10 is movably installed with a sponge block 19;

[0045] When the device is working, the robot is inserted along the initial end of the steel wire rope 5, so that the marking wheel 8 contacts the steel wire rope 5 and drives the telescopic rod 7 to contract by applying pressure, driving the sleeve column 9 to move toward the inner direction of the fixed tube 4, so that the No. 1 spring 15 and the No. 2 spring 16 are stretched, and the sealing block 18 blocks the connecting groove 17, and the walking mechanism 6 and the detection camera 2 are started, driving the base 1 and the marking ring 3 to move along the axial direction of the steel wire rope 5, and the detection camera 2 in the open state observes and detects the outer surface of the steel wire rope 5;

[0046] During the robot's movement, the marking wheel 8 and the outer surface of the steel wire rope 5 slide relative to each other. At this time, the compressed No. 1 spring 15 applies pressure to the anti-rust liquid 14, driving the sealing plate 13 along the No. 2 liquid outlet groove 12 into the inner cavity of the contact block 10, and then gradually immersing into the sponge block 19, and finally smearing the outer surface of the marking wheel 8 through the outer end opening of the contact block 10, so that the rotating marking wheel 8 evenly smears the sealing plate 13 on the outer surface of the steel wire rope 5;

[0047] By setting the marking wheel 8 to be in close contact with the outer surface of the steel wire rope 5 during operation, during the movement of the robot, the compressed No. 1 spring 15 applies pressure to the anti-rust liquid 14, driving the sealing plate 13 to penetrate into the inner cavity of the contact block 10 along the No. 1 liquid outlet groove 11, so that the sealing plate 13 is gradually immersed in the dye 20, and then gradually smeared on the outer surface of the marking wheel 8 through the opening of the contact block 10, so that the marking wheel 8 can omni-directionally smear the outer surface of the steel wire rope 5 during the rotation process, thereby focusing on increasing the anti-rust and anti-corrosion function of the bottom of the outer surface of the steel wire rope 5, and more sealing plates 13 are distributed to the bottom of the outer surface of the steel wire rope 5 through the fluidity of the sealing plate 13 and the action of gravity, thereby compensating for the excessive corrosion of the bottom of the outer surface of the steel wire rope 5, thereby synchronizing the corrosion cycle of each area of ​​the outer surface of the steel wire rope 5 and reducing the maintenance cost.

[0048] When the marking wheel 8 contacts the defective part of the steel wire rope 5, the notch on the outer surface of the steel wire rope 5 increases due to corrosion, and the marking wheel 8 loses its limiting support. At the same time, the No. 2 spring 16 drives the sleeve column 9 to move outward, so that the connecting groove 17 and the sealing block 18 are gradually staggered. The dye 20 located inside the fixed cylinder 4 leaks into the No. 2 liquid outlet tank 12 along the connecting groove 17, and is smeared on the outer surface of the marking wheel 8 through the contact block 10. The rotating marking wheel 8 drives the dye 20 outward and automatically smears it on the position near the corrosion area on the outer surface of the steel wire rope 5, completing the automatic marking. When the marking wheel 8 moves to the normal area on the outer surface of the steel wire rope 5, it drives the telescopic rod 7 and the sleeve column 9 to reset, so that the sealing block 18 automatically re-blocks the connecting groove 17, and the dye 20 no longer leaks outward.

[0049] By providing a marking ring 3 and a fixed cylinder 4, the marking wheel 8 is sleeved on the outer surface of the wire rope 5 in a staggered manner at equal angles, and the marking wheel 8 is movably connected to the outer end of the fixed cylinder 4 by providing a telescopic rod 7. The sleeve column 9 and the contact block 10 are driven by the second spring 16 to apply pressure to the marking wheel 8, so that during the movement, the sleeve column 9 drives the marking wheel 8 to apply pressure and contact the outer surface of the wire rope 5. When encountering the corrosion area on the outer surface of the wire rope 5, the gap caused by the corrosion is used to make the marking wheel 8 fall into it, and then the sleeve column 9 is driven by the second spring 16 to move to the outer end in the direction in which the opening of the fixed cylinder 4 points, so that the connecting groove 17 and the sealing block 18 are staggered, so that the dye 20 automatically penetrates into the second liquid outlet groove 12 along the connecting groove 17, and then is smeared on the outer surface of the marking wheel 8 through the contact block 10, and then the vicinity of the corrosion area on the outer surface of the wire rope 5 is automatically marked, thereby realizing an efficient automatic marking function.

[0050] The walking mechanism 6 includes a connecting frame 61, and two bearings 62 distributed on the left and right are fixedly installed on the top of the inner wall of the connecting frame 61. A connecting shaft 63 that passes through the top of the connecting frame 61 is fixedly sleeved inside the bearing 62. A walking wheel 65 is fixedly connected to the top of the connecting shaft 63. A gear 64 is fixedly sleeved on the outer surface of the connecting shaft 63. A motor 66 is fixedly installed on the bottom of the inner wall of the connecting frame 61. The output shaft of the motor 66 is fixedly connected to the right connecting shaft 63. The two walking wheels 65 are movably sleeved on the outer surface of the wire rope 5.

[0051] Start the connection frame 61 and drive the connection shaft 63 and the running wheel 65 to rotate. Under the transmission action of the gear 64, the two running wheels 65 rotate synchronously towards each other, thereby moving on the outer surface of the wire rope 5, driving the base 1 to move, thereby cooperating with the detection camera 2 to perform inspection operations.

[0052] The two ends of the first spring 15 are elastically connected to the rust-proof liquid 14 and the inner wall of the sleeve column 9 respectively. The first spring 15 is in a compressed state during operation, and the sealing plate 13 is located between the sleeve column 9 and the rust-proof liquid 14.

[0053] During operation, the two marking rings 3 are sleeved on the outer surface of the steel wire rope 5, so that the marking wheel 8 is in close contact with the outer surface of the steel wire rope 5 and relatively pressurized, driving the contact block 10 and the sleeve column 9 to move toward the inner direction of the fixed tube 4. At this time, the No. 1 spring 15 is compressed, thereby pressurizing the anti-rust liquid 14 during the subsequent movement, and then pushing the sealing plate 13 toward the contact block 10, thereby realizing the automatic coating function.

[0054] The dye 20 is sealed and filled between the outer surface of the sleeve column 9 and the inner wall of the fixed tube 4, and the sealing block 18 is in sealing contact with the outer surface of the sleeve column 9, and the height of the contact part is greater than the height of the connecting groove 17;

[0055] When the fixed tube 4 is sleeved on the outer surface of the wire rope 5, the pressure between the marking wheel 8 and the wire rope 5 drives the sleeve column 9 to move toward the inside of the fixed tube 4 until the sealing block 18 just blocks the position of the connecting groove 17. Only when the marking wheel 8 moves to the defective area of ​​the corroded outer surface of the wire rope 5, the marking wheel 8 that loses its support will move toward the defective area of ​​the wire rope 5 driven by the No. 2 spring 16, driving the sleeve column 9 to move toward the outside of the fixed tube 4, thereby staggering the connecting groove 17 and the sealing block 18, so that the dye 20 can seep out along the connecting groove 17 and complete the automatic marking.

[0056] The first liquid outlet groove 11 and the second liquid outlet groove 12 are respectively connected to the inner cavity of the contact block 10, the first liquid outlet groove 11 is a through-type design, and the second spring 16 is filled in the first liquid outlet groove 11;

[0057] The interior of the socket column 9 is provided with a No. 1 liquid outlet groove 11 and a No. 2 liquid outlet groove 12 which are isolated from each other. During operation, it can be ensured that the No. 1 liquid outlet groove 11 and the dye 20 will not interfere with each other. The sealing plate 13 can be immersed in the dye 20 along the No. 1 liquid outlet groove 11 under the action of the No. 1 spring 15 and the anti-rust liquid 14, and then complete the automatic coating protection function through the opening of the contact block 10.

[0058] The outer surface of the marking wheel 8 is movably sleeved with a rubber layer and is in limited contact with one end of the outer side of the contact block 10. The marking wheel 8 is in pressure contact with the steel wire rope 5 through the external rubber layer.

[0059] The rubber layer added to the outer surface of the marking wheel 8 can be in close contact with the marking wheel 8, which can reduce the wear on the wire rope 5 and reduce maintenance costs. At the same time, the marking wheel 8 that is deformed by pressure will automatically apply the No. 1 liquid outlet 11 and the dye 20 from the inside of the fixed cylinder 4 in the form of sealing-sealing release-sealing through mutual contact with the contact block 10, thereby avoiding waste of the sealing plate 13 during the application process.

[0060] Among them, the two marking rings 3 are symmetrically distributed on the front and rear sides of the detection camera 2, the number of fixed tubes 4 is six and evenly divided into two groups, the two groups of fixed tubes 4 are respectively located inside the two marking rings 3, and the axial deviation angle of the two groups of fixed tubes 4 around the wire rope 5 is 60°;

[0061] The stability of the base 1 during the operation is increased by providing two sets of mutually staggered marking rings 3 and fixed cylinders 4. The fixed cylinder 4 is movably connected to the marking wheel 8 through a telescopic rod 7, so that the marking wheel 8 can flexibly move along the axial direction of the fixed cylinder 4. The marking wheel 8 is stably supported by the cooperation of the No. 2 spring 16, the sleeve column 9 and the contact block 10, so that the marking wheel 8 is stably supported on the outer surface of the wire rope 5. The cooperation with the marking ring 3 greatly increases the stability of the base 1 during the movement.

[0062] The interior of the contact block 10 is divided into two independent cavities and connected to the second liquid outlet trough 12 and the first liquid outlet trough 11 respectively, and the sponge block 19 is filled in the left cavity inside the contact block 10;

[0063] The two independent cavities inside the contact block 10 are connected to the No. 1 liquid outlet 11 and the No. 2 liquid outlet 12 respectively, so as to avoid the No. 1 liquid outlet 11 and the No. 2 liquid outlet 12 from influencing each other, and the sponge block 19 absorbs the sealing plate 13 to avoid the sealing plate 13 from leaking too fast, thereby playing a slow release role.

[0064] The two ends of the second spring 16 are elastically connected to the fixing tube 4 and the sleeve column 9 respectively, and the second spring 16 is in a stretched state when working;

[0065] The No. 2 spring 16 is in a stretched state during operation. When the marking ring 3 is sleeved on the outer surface of the wire rope 5 through the marking wheel 8, the marking wheel 8 is pressed by the wire rope 5, thereby driving the contact block 10 and the sleeve column 9 to move toward the inner direction of the fixed tube 4, so that the No. 2 spring 16 is compressed. This provides movement conditions for the subsequent marking wheel 8 when encountering local depressions caused by corrosion on the outer surface of the wire rope 5, so that the stretched No. 2 spring 16 uses the rebound force to drive the sleeve column 9 to move, so that the connecting groove 17 and the sealing block 18 are staggered, and the dye 20 automatically seeps out to complete the automatic marking.

[0066] Working principle and usage process:

[0067] When the device is working, the robot is inserted along the initial end of the steel wire rope 5, so that the marking wheel 8 contacts the steel wire rope 5 and drives the telescopic rod 7 to contract by applying pressure, driving the sleeve column 9 to move toward the inner direction of the fixed tube 4, so that the No. 1 spring 15 and the No. 2 spring 16 are stretched, and the sealing block 18 blocks the connecting groove 17, and the walking mechanism 6 and the detection camera 2 are started, driving the base 1 and the marking ring 3 to move along the axial direction of the steel wire rope 5, and the detection camera 2 in the open state observes and detects the outer surface of the steel wire rope 5;

[0068] During the robot's movement, the marking wheel 8 and the outer surface of the steel wire rope 5 slide relative to each other. At this time, the compressed No. 1 spring 15 applies pressure to the anti-rust liquid 14, driving the sealing plate 13 along the No. 2 liquid outlet groove 12 into the inner cavity of the contact block 10, and then gradually immersing into the sponge block 19, and finally smearing the outer surface of the marking wheel 8 through the outer end opening of the contact block 10, so that the rotating marking wheel 8 evenly smears the sealing plate 13 on the outer surface of the steel wire rope 5;

[0069] When the marking wheel 8 contacts the defective part of the wire rope 5, the gap on the outer surface of the wire rope 5 increases due to corrosion, and the marking wheel 8 will lose its limiting support. At the same time, the No. 2 spring 16 drives the sleeve column 9 to move outward, so that the connecting groove 17 and the sealing block 18 are gradually staggered, and the dye 20 located inside the fixed cylinder 4 leaks into the No. 2 liquid outlet groove 12 along the connecting groove 17, and is smeared on the outer surface of the marking wheel 8 through the contact block 10. The rotating marking wheel 8 drives the dye 20 outward and automatically smears it on the vicinity of the corrosion area on the outer surface of the wire rope 5 to complete the automatic marking. When the marking wheel 8 moves to the normal area on the outer surface of the wire rope 5, it will drive the telescopic rod 7 and the sleeve column 9 to reset, so that the sealing block 18 automatically re-blocks the connecting groove 17, and the dye 20 no longer leaks outward.
