Technical Field

[0001] The utility model relates to the technical field of maintenance operations of wind power tower barrels, and particularly relates to a suspension device. Background Art

[0002] As an important component of wind power generation equipment, the wind power tower barrel mainly plays a supporting role. When the wind power tower barrel is in use, the weld seams need to be regularly inspected and repaired if necessary. At present, a magnetic climbing robot carrying an ultrasonic detection probe is mainly used to detect the weld seams of the wind power tower barrel. However, when the existing magnetic climbing robot is operating, the auxiliary equipment it needs to carry has a certain weight, and directly hanging it on the robot will increase the safety risk of the robot falling.

[0003] Therefore, it is necessary to provide a new suspension device to solve the above technical problems. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a suspension device, aiming to solve the technical problem of large safety risks when the existing magnetic climbing robot is operating.

[0005] To achieve the above purpose, a suspension device proposed by the utility model includes:

[0006] A circular rope, which is used to be sleeved on the wind power tower barrel and is connected to a hoist at the top of the wind power tower barrel through a suspension rope;

[0007] A water bag, which is arranged on the circular rope;

[0008] A magnetic climbing robot, which is connected to the water bag through a spring water pipe;

[0009] A cable, which is arranged on the circular rope, and the cable is electrically connected to the magnetic climbing robot.

[0010] In an embodiment, a plurality of rollers are arranged at intervals on the circular rope.

[0011] In an embodiment, locking buckles are arranged at both ends of each roller, and the locking buckles are connected to the circular rope.

[0012] In an embodiment, a tensioner is arranged on the circular rope.

[0013] In an embodiment, the suspension device further includes an anti-falling component, and the magnetic climbing robot is connected to the circular rope through the anti-falling component.

[0014] In an embodiment, the anti-falling component includes an anti-falling device and a pulling rope connected to the anti-falling device. The anti-falling device is arranged on the circular rope, and the magnetic climbing robot is connected to the end of the pulling rope far away from the anti-falling device.

[0015] In one embodiment, the number of the anti-falling devices is two. The two anti-falling devices are arranged at intervals on the annular rope, and each anti-falling device is correspondingly connected with a pulling rope. The magnetic climbing robot is connected with the corresponding anti-falling device through the pulling rope.

[0016] In one embodiment, the magnetic climbing robot includes a main body, a driving member, a driven wheel set and two permanent magnet wheel sets. The driven wheel set and each permanent magnet wheel set are rotatably arranged on the main body; the driving member is arranged on the main body and is used for driving the permanent magnet wheel set to rotate.

[0017] In one embodiment, the permanent magnet wheel set includes a transmission shaft, an armature, a rubber wheel and a permanent magnet. The armature, the rubber wheel and the permanent magnet are all connected with the driving member through the transmission shaft.

[0018] In one embodiment, a scraping piece is arranged on the main body at a position corresponding to the permanent magnet.

[0019] The technical solution of the present utility model adopts an annular rope to suspend loads such as water bags and cables required for the operation of the magnetic climbing robot, which can reduce the load weight carried by the magnetic climbing robot, thereby reducing the high-altitude operation risk of the magnetic climbing robot; moreover, it can also reduce the indentation generated when the magnetic climbing robot travels on the surface of the wind power tower. In this embodiment, the water bag is used to store the detection reagent, which can spray the detection reagent to the detection area through a spring water pipe when the magnetic climbing robot detects the weld seam, so as to improve the accuracy of the detection data. The cable is used to realize the electrical connection between the magnetic climbing robot and an external control device, and the magnetic climbing robot is used to detect the weld seam on the surface of the wind power tower. The annular rope is sleeved on the wind power tower and is used to suspend the water bag, cable, etc. required for the magnetic climbing robot to detect the weld seam; and the annular rope is connected with a crane at the top of the wind power tower through a suspension rope. When adjusting the height of the annular rope, by controlling the operation of the crane and taking in and releasing the suspension rope, the annular rope can be driven to rise and fall to adjust the height of the annular rope. This suspension device suspends the water bag and cable required for the magnetic climbing robot to detect the operation through the annular rope, that is, the weights of the cable, water bag and other objects are all borne by the annular rope, which can reduce the load that the magnetic climbing robot needs to carry, thereby reducing the high-altitude operation risk of the magnetic climbing robot; moreover, as the load is reduced, the magnetic suction force of the magnetic climbing robot adsorbed on the wind power tower can also be correspondingly reduced, which can reduce or even eliminate the indentation left by the magnetic climbing robot during the detection operation on the wind power tower. In addition, by using an annular rope sleeved on the wind power tower to suspend loads such as water bags and cables, the positions of the water bag and cable can be relatively fixed, that is, it can avoid the water bag, cable and other loads from fluttering with the wind under the action of the wind, thereby reducing potential safety hazards. This suspension device is applied to technical fields such as wind power tower maintenance operations and weld seam detection. Description of the Drawings

[0031] As an important component of wind power generation equipment, the wind power tower mainly plays a supporting role, and its height is often more than 100 meters. The weld inspection of the wind power tower is mainly completed by a magnetic climbing robot. During the actual operation process, researchers found that when the magnetic climbing robot inspects the weld, it not only needs to carry the corresponding inspection equipment, but also needs to carry a large amount of fresh water and cables. This will increase the load of the magnetic climbing robot and increase the risk of high-altitude inspection. At the same time, due to the increase in load, in order to prevent the magnetic climbing robot from falling off, it is also necessary to increase the magnetic suction of the magnetic climbing robot, which will leave a deeper indentation on the surface of the wind power tower. In some related technologies, although the load such as fresh water and cables is suspended by the suspension rope lowered from the crane at the top of the wind power tower, although it can reduce the load that the magnetic climbing robot needs to carry, the use of the suspension rope to suspend the load will cause the load to easily sway with the wind under the action of the wind, posing a very large potential safety hazard.

[0032] The present utility model provides a suspension device, aiming to solve the technical problem of large safety risks when the existing magnetic climbing robot is operating.

[0033] Please refer to Figure 1 , in an embodiment of the present utility model, the suspension device includes an annular rope 100, a water bag 200, a magnetic climbing robot 300, and a cable 400. The annular rope 100 is used to be sleeved on the wind power tower 600 and is connected to the crane at the top of the wind power tower 600 through a suspension rope 700. The water bag 200 is arranged on the annular rope 100. The magnetic climbing robot 300 is connected to the water bag 200 through a spring water pipe 210. The cable 400 is arranged on the annular rope 100, and the cable 400 is electrically connected to the magnetic climbing robot 300.

[0034] The technical solution of the present utility model uses an annular rope 100 to suspend loads such as the water bag 200 and the cable 400 required for the operation of the magnetic climbing robot 300, which can reduce the load weight carried by the magnetic climbing robot 300, thereby reducing the high-altitude operation risk of the magnetic climbing robot 300; and it can also reduce the indentation generated when the magnetic climbing robot 300 travels on the surface of the wind power tower 600. In this embodiment, the water bag 200 is used to store the detection reagent (such as a solution containing dishwashing liquid), and it can spray the detection reagent to the detection area through the spring water pipe 210 when the magnetic climbing robot 300 detects the weld seam, so as to improve the accuracy of the detection data. The cable 400 includes a cable, a communication network cable, etc. The cable 400 is used to realize the electrical signal connection between the magnetic climbing robot 300 and an external control device, and the magnetic climbing robot 300 is used to detect the weld seam on the surface of the wind power tower 600. The annular rope 100 is sleeved on the wind power tower 600 and is used to suspend the water bag 200, the cable 400, etc. required when the magnetic climbing robot 300 detects the weld seam; and the annular rope 100 is connected to the crane at the top of the wind power tower 600 through the suspension rope 700. When adjusting the height of the annular rope 100, by controlling the operation of the crane and taking in and releasing the suspension rope 700, the annular rope 100 can be driven to lift and lower to adjust the height of the annular rope 100. This suspension device suspends the water bag 200 and the cable 400 required during the detection operation of the magnetic climbing robot 300 by sleeving the annular rope 100, that is, the weights of objects such as the cable 400 and the water bag 200 are all borne by the annular rope 100, which can reduce the load that the magnetic climbing robot 300 needs to carry, thereby reducing the high-altitude operation risk of the magnetic climbing robot 300; and with the reduction of the load, the magnetic suction force of the magnetic climbing robot 300 adsorbed on the wind power tower 600 can also be correspondingly reduced, which can reduce or even eliminate the indentation left by the magnetic climbing robot 300 during the detection operation on the wind power tower 600. In addition, by using the annular rope 100 sleeved on the wind power tower 600 to suspend loads such as the water bag 200 and the cable 400, it can make the positions of the water bag 200 and the cable 400 relatively fixed, that is, it can prevent loads such as the water bag 200 and the cable 400 from fluttering in the wind under the action of the wind, thereby reducing potential safety hazards. This suspension device is applied to technical fields such as the maintenance operation and weld seam detection of the wind power tower 600.

[0035] In the embodiment of the present utility model, to ensure the structural strength of the annular rope 100, the annular rope 100 is selected as a steel wire rope; and the electrical signal connection between the cable and the magnetic climbing robot is realized through a spring wire, and the cable of the cable 400 is also of a spring structure.

[0036] Please refer to Figure 1, in an embodiment of the present utility model, a plurality of rollers 110 are arranged at intervals on the annular rope 100. When controlling the operation of the crane to retract and extend the lifting rope 700 and driving the annular rope 100 to lift and lower, the annular rope 100 moves up and down on the wind power tower barrel 600 through the plurality of rollers 110, which can reduce the difficulty of height adjustment of the annular rope 100. Correspondingly, by means of the rollers 110, the difficulty of height adjustment of the annular rope 100 is reduced, which can reduce the output power requirement of the crane, that is, a crane with a smaller power can be used to drive the annular rope 100 to lift and lower, and the cost can be reduced.

[0037] In an embodiment of the present utility model, locking buckles are arranged at both ends of each roller 110, and the locking buckles are connected to the annular rope 100. Specifically, both ends of each roller 110 are connected to the annular rope 100 through the locking buckles, which can fix the position of the roller 110 to prevent relative movement between the roller 110 and the annular rope 100.

[0038] In an embodiment of the present utility model, a tensioner is arranged on the annular rope 100. Specifically, the shape of the wind power tower barrel 600 is usually cylindrical, and the diameter of the wind power tower barrel 600 gradually decreases with the increase of height, that is, the wind power tower barrel 600 is a cylinder with a gradually decreasing diameter from bottom to top. The tensioner is used to adjust the tension of the annular rope 100, which can gradually tighten the annular rope 100 when the annular rope 100 moves from bottom to top to ensure that the annular rope 100 always adheres to the surface of the wind power tower barrel 600, thereby ensuring the stability and safety of the suspension device.

[0039] Please refer to Figure 1 , in an embodiment of the present utility model, the suspension device further includes an anti-falling component 500, and the magnetic climbing robot 300 is connected to the annular rope 100 through the anti-falling component 500. Specifically, the anti-falling component 500 is similar to the function of the safety rope. It can timely hold the magnetic climbing robot 300 when the magnetic climbing robot 300 suddenly stops running and instantaneously falls, so as to prevent the magnetic climbing robot 300 from directly falling to the ground and ensure the safety of the magnetic climbing robot 300.

[0040] Please refer to Figure 1, in an embodiment of the present utility model, the anti-falling assembly 500 includes an anti-falling device 510 and a pulling rope 520 connected to the anti-falling device 510. The anti-falling device 510 is arranged on the annular rope 100, and the magnetic climbing robot 300 is connected to one end of the pulling rope 520 away from the anti-falling device 510. In this embodiment, the anti-falling device 510 is similar to the retractor of an automobile seat belt. Specifically, when the magnetic climbing robot 300 performs weld inspection, the magnetic climbing robot 300 will slowly pull out the pulling rope 520. When the magnetic climbing robot 300 suddenly stops running and instantly falls, the magnetic climbing robot 300 will apply a pulling force with a relatively fast speed and large force to the pulling rope 520. At this time, the anti-falling device 510 will lock the pulling rope 520 to prevent the pulling rope 520 from being pulled out, thereby avoiding the sudden fall of the magnetic climbing robot 300 and ensuring the safety of the magnetic climbing robot 300.

[0041] In an embodiment of the present utility model, the number of the anti-falling devices 510 is two. The two anti-falling devices 510 are arranged on the annular rope 100 at intervals, and each anti-falling device 510 is correspondingly connected with a pulling rope 520. The magnetic climbing robot 300 is connected to the corresponding anti-falling device 510 through the pulling rope 520. Specifically, by using the two anti-falling devices 510 to hold the magnetic climbing robot 300 simultaneously, it can further ensure the safety of the magnetic climbing robot 300. Specifically, when the magnetic climbing robot 300 suddenly stops running and instantly falls, if one of the anti-falling devices 510 fails, the other anti-falling device 510 can still prevent the magnetic climbing robot 300 from suddenly falling and ensure the safety of the magnetic climbing robot 300.

[0042] Please refer to Figure 2 and Figure 3 , in an embodiment of the present utility model, the magnetic climbing robot 300 includes a main body 310, a driving member 320, a driven wheel set 330 and two permanent magnet wheel sets 340. The driven wheel set 330 and each permanent magnet wheel set 340 are rotatably arranged on the main body 310; the driving member 320 is arranged on the main body 310 and is used to drive the permanent magnet wheel set 340 to rotate. Specifically, the driving member 320 is used to drive the permanent magnet wheel set 340 to rotate to realize the movement of the magnetic climbing robot 300. The permanent magnet wheel set 340 can provide a certain magnetic attraction force to ensure that the magnetic climbing robot 300 can be adsorbed on the surface of the wind power tower barrel 600. In a specific embodiment, the two permanent magnet wheel sets 340 are arranged on the main body 310 at intervals, and the driven wheel set 330 is arranged on one side of the connection line of the two permanent magnet wheel sets 340.

[0043] Please refer to Figure 2 and Figure 3, in an embodiment of the present utility model, the permanent magnet wheel set 340 includes a transmission shaft, an armature 341, a rubber wheel 342, and a permanent magnet 343. The armature 341, the rubber wheel 342, and the permanent magnet 343 are all connected to the driving member 320 through the transmission shaft. The combination of the armature 341, the rubber wheel 342, and the permanent magnet 343 can have various different combination forms: The rubber wheel 342 can be one and is arranged on the outer side of one side of the magnetic wheel set; it can also be two and are respectively placed on the outer sides of both sides of the permanent magnet wheel set 340; One permanent magnet 343 is located between two armatures 341 and also in the middle of the permanent magnet wheel set 340. In this way, the suction force is large, but the mass increases; it can also be one permanent magnet 343 and one armature 341, and the permanent magnet 343 is located between the rubber wheel 342 and the armature 341. In this way, the suction force is small, but the mass decreases. Specifically, the permanent magnet wheel set 340 can be arranged in sequence according to the order of the rubber wheel 342, the armature 341, the permanent magnet 343, the armature 341, and the rubber wheel 342. The structure of each permanent magnet wheel set 340 is the same. The rubber wheel 342 can be a hard rubber wheel or a hard rubber is covered on the outer periphery of an iron disk. The diameter of the rubber wheel 342 is larger than the diameter of the permanent magnet 343. In this way, during the rolling process of the magnetic climbing robot 300 on the surface of the equipment to be derusted, the rubber wheel 342 contacts the surface of the equipment and rolls on the surface of the equipment, while there is a certain gap between the permanent magnet 343 and the surface of the wind power tower 600. In this way, the magnetic climbing robot 300 can be adsorbed on the surface of the equipment by the magnetic suction force between the permanent magnet 343 and the surface of the equipment and will not fall off, and it is ensured that the permanent magnet 343 will not contact the surface of the wind power tower 600, avoiding the collision between the permanent magnet 343 and the iron wind power tower 600 surface and causing breakage. After multiple tests, the permanent magnet wheel set 340 can generate a sufficiently large magnetic adsorption force, which can ensure that equipment weighing from dozens of kilograms to hundreds of kilograms can be stably adsorbed on the iron wall surface. In addition, the number of the permanent magnets 343 and the armatures 341 can also be multiple, and each armature 341 and each permanent magnet 343 are arranged alternately. The magnetic suction force between the permanent magnet 343 and the surface of the wind power tower 600 can make the magnetic climbing robot 300 adsorbed on the surface of the wind power tower 600. The armature 341 is used to increase the magnetic suction force. The number of the permanent magnets 343 and the armatures 341 can also be multiple, and multiple permanent magnets 343 and armatures 341 are arranged alternately. The permanent magnets 343 and the armatures 341 can be made into circles with the same shape and size.

[0044] In a specific embodiment, the driven wheel set 330 can be either a single rubber wheel 342 or a universal wheel, and the structure of the driven wheel set 330 can also be designed to be the same as that of the permanent magnet wheel set 340 to increase the magnetic suction force of the magnetic climbing robot 300 and prevent the magnetic climbing robot 300 from falling.

[0045] Please refer to Figure 3, in an embodiment of the present utility model, a scraping blade 311 is provided on the main body 310 corresponding to the position of the permanent magnet 343. Since the permanent magnet 343 is used and the magnetic climbing robot travels on an iron wall surface, iron filings or rust will adhere to the permanent magnet wheel set 340, which easily causes the gap between the permanent magnet 343 and the iron wall surface to be too large, reducing the magnetic suction force and easily causing the risk of the magnetic climbing robot 300 falling. The scraping blade 311 is provided to timely remove excessive rust slag on the permanent magnet wheel set 340, which can ensure the magnetic suction force of the permanent magnet wheel set 340 and prevent the magnetic climbing robot 300 from falling due to too small magnetic suction force. Specifically, the scraping blade 311 is specifically arranged in the direction tangent to the permanent magnet 343 and the armature 341, and the set spacing is 1 mm to 10 mm, which is convenient for scraping the rust slag adsorbed by the armature 341 and the permanent magnet 343 during travel and does not affect the rotation of the armature 341 and the permanent magnet 343. The scraping blade 311 can be fixed on the main body 310 or movably arranged on the main body 310 to facilitate manual adjustment of the height of the scraping blade 311.

[0046] The above description is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
