Description

Technical Field

[0001] The present application relates to the field of flaw detection, and in particular to a remotely controlled cylindrical wind power tower flaw detection device. Background Art

[0002] With the popularity of high towers, tower quality has become an increasingly important concern during operation. The damage to the welds between each tower platform is not easy to detect during operation, and hidden dangers in operation are prominent. Therefore, regular inspection and maintenance of wind power towers is particularly important.

[0003] Traditional wind turbine tower inspection methods usually require manual entry into or outside the tower for direct inspection, which is not only time-consuming and laborious, but also requires good weather conditions during operation, and has significant safety risks. Especially for high-altitude operations, the life safety of operators is difficult to guarantee.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology: the damage at the welding points between each layer of the tower platform is not easy to find during operation, the operation hidden dangers are prominent, manual inspection is time-consuming and labor-intensive, and there are safety hazards. Therefore, a remote-controlled cylindrical wind power tower flaw detection equipment is now proposed. Summary of the invention

[0005] In order to improve the problem that damage at the welding points between each layer of the tower platform is not easy to find during operation, hidden dangers in operation are prominent, manual inspection is time-consuming and labor-intensive, and there are safety hazards, the present application provides a remote-controlled cylindrical wind power tower flaw detection equipment.

[0006] The present application provides a remote-controlled cylindrical wind power tower flaw detection device, which adopts the following technical solution:

[0007] A remote-controlled cylindrical wind power tower flaw detection device comprises a central transmission box and mounting frames fixedly mounted on both sides of the outer wall of the central transmission box, one side of the outer wall of the central transmission box is fixedly connected to a motor box, the upper and lower sides of the central transmission box are fixedly connected to a power transmission box, and the side of the outer wall of the central transmission box away from the motor box is slidably connected to a stabilizing box;

[0008] The central transmission box, the power transmission box and the stabilizing box are provided with transmission components inside; the motor box is provided with a driving motor for driving the transmission components inside; a pressure maintaining component is provided on the side of the outer wall of the power transmission box close to the stabilizing box; a crawling component is provided on the side of the pressure maintaining component away from the power transmission box; a stabilizing component is provided inside the stabilizing box; a dust removal component is provided above the side of the outer wall of the stabilizing box and the mounting frame away from the central transmission box; and a detection component is provided below the side of the outer wall of the stabilizing box and the mounting frame away from the central transmission box.

[0009] In summary, this application has the following beneficial effects:

[0010] 1. This application cooperates with a central transmission box, a mounting frame, a motor box, a power transmission box, a stabilizing box, a transmission assembly, a drive motor, a pressure maintaining assembly, a crawling assembly, a stabilizing assembly, a dust removal assembly and a detection assembly. Before use, the surface of the tower is cleaned first. After the water stains on the surface of the tower are basically air-dried after cleaning, the central transmission box and the mounting frame are fixed to each other to complete the overall assembly of the equipment. When in use, the pressure maintaining assembly can make the equipment adapt to towers of different specifications and maintain good friction between the tower and the crawling assembly, thereby improving the stability of the equipment during climbing and descending. The drive motor can be driven by the transmission The moving component transmits the torque to the crawling component, thereby realizing the climbing and descending of the equipment. When the equipment moves to the area to be inspected, the stabilizing component can maximize the stability of the equipment when inspecting the tower weld, effectively ensuring the inspection effect of the equipment. At the same time, before the equipment is inspected, the dust removal component performs a certain degree of dust removal on the weld to avoid the small amount of dust reattached to the tower surface from affecting the inspection effect of the equipment. Then the inspection component performs flaw detection on the tower weld, thereby ensuring the good stability of the equipment during operation while ensuring the inspection effect of the equipment as much as possible, avoiding the safety problems existing in manual inspection.

[0011] 2. This application uses the cooperation of a detection ring, a detection box, a second arc-shaped rack, a detection motor, a detection gear, a detection slide, a detection connecting plate, a detection pulley, an infrared flaw detector, and an ultrasonic variable-distance probe. After the dust removal assembly has removed dust to a certain extent on the weld area on the outer wall of the tower that needs to be inspected, the detection motor drives the detection gear to rotate, and then the detection box rotates along the detection ring. While the detection box rotates, the infrared flaw detector and the ultrasonic variable-distance probe inspect the tower weld, so that the equipment can perform 360° flaw detection on the tower weld without blind spots, thereby further ensuring the flaw detection effect of the equipment.

[0025] The following is combined with Figure 1-11 This application is described in further detail.

[0026] Please refer to Figure 1 , Figure 2 and Figure 3 , a remote-controlled cylindrical wind power tower flaw detection equipment, comprising a central transmission box 1 and mounting frames 2 fixedly mounted on both sides of the outer wall of the central transmission box 1 (the mounting frame 2 should use as little material as possible and as light a material as possible while meeting the strength requirements, so as to minimize the weight of the equipment after installation, thereby minimizing the energy consumption of the equipment and making the equipment easier to install and transport);

[0027] Reference Figure 2 , Figure 3 and Figure 4, both sides of the outer wall of the central transmission box 1 and the two ends of the mounting frame 2 should be fixedly connected with mounting plates, and threaded grooves are provided at the four corners of the mounting plate. The staff needs to first place the central transmission box 1 symmetrically around the tower along the center of the tower, and then place the mounting frame 2 between the two adjacent central transmission boxes 1, align the mounting plate and the threaded grooves at the four corners of the mounting plate, and then thread them into bolts to complete the overall assembly of the equipment. One side of the outer wall of the central transmission box 1 is fixedly connected with a motor box 3, and the center of the upper and lower surfaces of the motor box 3 are fixedly connected with an infrared distance sensor 13 (the infrared distance sensor 13 arranged on the upper and lower surfaces of the motor box 3 can detect the distance between the motor box 3 and the cabin at the top of the tower and the ground under the tower, and then measure the specific height of the equipment during the climbing process), the upper and lower sides of the central transmission box 1 are fixedly connected with a power transmission box 4, and the side of the outer wall of the central transmission box 1 away from the motor box 3 is fixedly connected with a stabilizing box 5;

[0028] Reference Figure 4 and Figure 5 The central transmission box 1, the power transmission box 4 and the stabilizing box 5 are provided with a transmission assembly 6, the motor box 3 is provided with a driving motor 7 (the driving motor 7 is a stepping motor with a brake function) for driving the transmission assembly 6, and the outer wall of the power transmission box 4 is provided with a pressure maintaining assembly 8 on the side close to the stabilizing box 5. The pressure maintaining assembly 8 includes an adjusting cylinder 801 fixedly connected to the outer wall of the power transmission box 4, the output end of the adjusting cylinder 801 is fixedly connected to the outer sleeve 802, and the inner part of the outer sleeve 802 is slidably connected to the connecting block 803 ( The inner wall of the outer sleeve 802 should be provided with a limiting groove, and the outer wall of the connecting block 803 should be fixedly connected with a limiting block adapted to the limiting groove, so as to prevent the connecting block 803 from falling off from the inner part of the outer sleeve 802 as much as possible. At the same time, the outer wall of the outer sleeve 802 should be provided with reinforcing ribs, so as to improve the structural strength of the outer sleeve 802 as much as possible while ensuring that the dead weight of the equipment is not seriously increased as much as possible). The inner part of the outer sleeve 802 is sleeved with a first pressure spring 804, and the end of the first pressure spring 804 away from the outer sleeve 802 is fixedly connected to the connecting block 803;

[0029] Reference Figure 4 , Figure 5 and Figure 6, a crawling assembly 9 is arranged on the side of the pressure maintaining assembly 8 away from the power transmission box 4, and the crawling assembly 9 includes a rubber track 901 (in terms of weight, the rubber track 901 is lighter than the metal track and the hard plastic track, which helps to reduce the overall weight of the equipment and improve the flexibility of the equipment. In terms of use, the surface of the rubber track 901 has better adhesion and friction, which enables the equipment as a whole to climb and move more stably on the surface of the tower. In particular, the tower itself has a certain curvature. When the rubber track 901 is squeezed and attached to the surface of the tower, a certain deformation will occur, so that the fitting area between the two is larger, which can further increase the friction between the two). Active driving wheels 902 are arranged at both ends of the rubber track 901, and driven wheels 903 are evenly arranged between the two active driving wheels 902. A crawling bevel gear 904 for driving the active driving wheel 902 to rotate is fixedly connected to the center of the active driving wheel 902. After the equipment is installed around the outside of the tower, the output end of the adjusting cylinder 801 First, it moves toward the tower, driving the outer sleeve 802, the connecting block 803, the first pressure spring 804, and the rubber track 901 to move toward the tower, and then adjusting the distance between the rubber track 901 and the tower, so that the equipment can adapt to more towers with different diameters. When the rubber track 901 abuts against the surface of the tower, the adjusting cylinder 801 moves a certain distance toward the tower again to compress the first pressure spring 804 (due to the particularity of the overall shape of the sleeve being narrow at the top and wide at the bottom, the diameter of the tower part close to the rubber track 901 is constantly changing during the climbing process of the equipment. When the equipment is climbing upward, the first pressure spring 804 is slowly released, while constantly squeezing the connecting block 803, and then squeezing the crawling component 9. When the equipment rises a certain distance, the adjusting cylinder 801 will drive the outer sleeve 802 to move toward the tower again, and squeeze the first pressure spring 804 that has been released to a certain extent again, so as to ensure good friction and stability when the equipment climbs upward).

[0030] Reference Figure 4 and Figure 7The transmission assembly 6 includes a first transmission rod 601 fixedly connected to the output end of the driving motor 7. The outer wall of the first transmission rod 601 is located on one side of the central transmission box 1 and is slidably connected to a sliding sleeve 602. The outer wall of the sliding sleeve 602 is fixedly connected to a first ratchet 603 (a limiting groove should be provided on the outer wall of the first transmission rod 601, and a limiting block matched with the limiting groove is fixedly connected to the inner wall of the sliding sleeve 602. The limiting block slides in the limiting groove, thereby realizing the sliding connection of the sliding sleeve 602 to the first transmission rod 601, and the first transmission rod 601 rotates When the sliding sleeve 602 is moving, the first ratchet 603 fixedly connected to the outer wall of the sliding sleeve 602 rotates synchronously with the first transmission rod 601), one side of the inner wall of the central transmission box 1 is rotatably connected to the first bevel gear 604, the inner wall of the first bevel gear 604 is provided with a first pawl 605 meshing with the first ratchet 603, the side of the inner wall of the central transmission box 1 away from the first bevel gear 604 is rotatably connected to the second bevel gear 606, the inner wall of the second bevel gear 606 is provided with a second pawl 607 meshing with the first ratchet 603, and the central transmission Electric cylinders 608 are provided on both sides of the inner wall of the moving box 1 for driving the sliding sleeve 602 to slide along the first transmission rod 601 (the moving direction of the output end of the electric cylinder 608 should be parallel to the first transmission rod 601, and the two ends of the outer wall of the sliding sleeve 602 should be rotatably connected with connecting rods through bearings, and the end of the connecting rod away from the sliding sleeve is fixedly connected to the output end of the electric cylinder 608, so that the electric cylinder 608 can drive the sliding sleeve 602 to slide along the first transmission rod 601 without affecting the sliding sleeve 602 to rotate with the first transmission rod 601). When in use, the electric cylinder 60 8 can drive the sliding sleeve 602 to slide along the first transmission rod 601, thereby adjusting the position of the first ratchet 603 (the inner side walls of the first bevel gear 604 and the second bevel gear 606 are respectively provided with baffles on both sides of the first pawl 605 and the second pawl 607, and the baffle close to the first ratchet 603 is inclined to both sides, thereby trying to avoid the first ratchet 603 from hitting the first pawl 605 and the second pawl 607 when the first ratchet 603 follows the sliding sleeve 602 to slide and mesh with the first pawl 605 and the second pawl 607);

[0031] Reference Figure 7 , Figure 8 and Fig. 9 , a second transmission rod 609 is rotatably connected in the power transmission box 4, and one end of the second transmission rod 609 located in the central transmission box 1 is fixedly connected to a third bevel gear 610 meshing with the first bevel gear 604 and the second bevel gear 606 (the first bevel gear 604 and the second bevel gear 606 are respectively located on both sides of the third bevel gear 610 and are symmetrically distributed). When the electric cylinder 608 drives the sliding sleeve 602 to move to the first ratchet 603 and mesh with the first pawl 605, the driving motor 7 drives the first transmission rod 601 along Figure 7When the first ratchet wheel 603 rotates in the middle f direction, it cannot drive the first pawl 605 and the first bevel gear 604 to rotate. Figure 7 When the first ratchet wheel 603 rotates in the direction of e, the first ratchet wheel 603 drives the first ratchet pawl 605 and the first bevel gear 604 to rotate in the same direction. Figure 7 When the electric cylinder 608 drives the sliding sleeve 602 to move to the first ratchet wheel 603 and the second ratchet pawl 607, the driving motor 7 drives the first transmission rod 601 along the Figure 7 When the first ratchet wheel 603 rotates in the middle f direction, it cannot drive the second ratchet 607 and the second bevel gear 606 to rotate. Figure 7 When the first ratchet wheel 603 rotates in the middle e direction, the second ratchet pawl 607 and the second bevel gear 606 also rotate in the middle e direction. Figure 7 The first bevel gear 604 and the second bevel gear 606 are both meshed with the third bevel gear 610, and the two are respectively located on both sides of the third bevel gear 610 and are symmetrically distributed. Therefore, when the first ratchet 603 drives the two to rotate in the same direction, the third bevel gear 610 rotates in the opposite direction. The outer wall of the second transmission rod 609 is located in the power transmission box 4 and is fixedly connected to the fourth bevel gear 611 on both sides of the active driving wheel 902. The inner wall of the power transmission box 4 is rotatably connected to the transmission sleeve 612. One end of the transmission sleeve 612 close to the fourth bevel gear 611 is fixedly connected to the fifth bevel gear 612 meshed with the fourth bevel gear 611. 13. The transmission sleeve 612 is internally slidably connected with a transmission sleeve rod 614 (a cross slot is provided inside the transmission sleeve 612, and one end of the transmission sleeve rod 614 close to the transmission sleeve 612 is fixedly connected with a cross slide rod adapted to the cross slot, and the cross slide rod is slidably connected in the cross slot. When the transmission sleeve 612 rotates, the cross slide rod and the cross slot transmit the rotation of the transmission sleeve 612 to the transmission sleeve rod 614, thereby realizing the rotation of the transmission sleeve 612 and driving the transmission sleeve rod 614 to rotate), and one end of the transmission sleeve rod 614 away from the transmission sleeve 612 is fixedly connected with a sixth bevel gear 615 meshing with the creeping bevel gear 904. When the first bevel gear 604 moves along Figure 7 When the third bevel gear 610 rotates in the direction of e (the second bevel gear 606 rotates in the direction of Figure 7The third bevel gear 610 drives the second transmission rod 609 and the fourth bevel gear 611 to rotate, and the fourth bevel gear 611 drives the transmission sleeve 612, the transmission sleeve rod 614 and the sixth bevel gear 615 to rotate through the fifth bevel gear 613, so that the sixth bevel gear 615 drives the crawling bevel gear 904 and the active driving wheel 902 to rotate, so that the rubber crawler 901 climbs up along the tower. When the second bevel gear 606 rotates in the e direction in the figure, driving the third bevel gear 610 to rotate (at this time, the first bevel gear 604 idles in the f direction in the figure), the third bevel gear 610 drives the second transmission rod 609 and the fourth bevel gear 611 to rotate, and the fourth bevel gear 611 drives the transmission sleeve 612, the transmission sleeve rod 614 and the sixth bevel gear 615 to rotate through the fifth bevel gear 613, and then the sixth bevel gear 615 drives the crawling bevel gear 904 and the active driving wheel 902 to rotate, so that the rubber crawler 901 climbs up along the tower. The three-bevel gear 610 drives the second transmission rod 609 and the fourth bevel gear 611 to rotate, and the fourth bevel gear 611 drives the transmission sleeve 612, the transmission sleeve rod 614 and the sixth bevel gear 615 to rotate through the fifth bevel gear 613, so that the sixth bevel gear 615 drives the crawling bevel gear 904 and the active driving wheel 902 to rotate, so that the rubber track 901 moves downward along the tower, and when the rubber track 901 moves downward along the tower, after the rubber track 901 drives the equipment to move downward for a certain distance, the regulating cylinder 801 will drive the outer sleeve 802 to the side away from the tower The first pressure spring 804 is moved to avoid that when the first pressure spring 804 reaches the compression limit, the distance between the rubber tracks 901 is fixed and smaller than the diameter of the tower below, making it difficult for the equipment to move downward. The outer wall of the transmission sleeve 614 is rotatably connected to the side of the transmission sleeve 612 away from the transmission sleeve 612 (the push-pull sleeve 616 is rotatably connected to the transmission sleeve 614 through a bearing, so that the push-pull sleeve 616 can drive the transmission sleeve 614 to slide and connect to the transmission sleeve 612 without affecting the rotation of the transmission sleeve 614 and the transmission sleeve 612). The push-pull sleeve 616 is fixed at one end away from the transmission sleeve 614 Connected to the connecting block 803 (the connection between the push-pull sleeve 616 and the connecting block 803 should have a certain degree of elastic deformation ability), when the equipment climbs and moves down, the distance between the crawling bevel gear 904 and the fifth bevel gear 613 will change with the change of the tower diameter, but the change in the distance between the two is equal to the change in the distance between the connecting block 803 and the outer wall of the power transmission box 4. When the connecting block 803 is displaced, the push-pull sleeve 616 can drive the transmission sleeve rod 614 to move synchronously, thereby keeping the sixth bevel gear 615 and the crawling bevel gear 904 in meshing;

[0032] Reference Figure 4 , Fig.10 and Fig.11A stabilizing assembly 10 is arranged inside the stabilizing box 5, and the stabilizing assembly 10 includes a stabilizing sleeve 1001 slidably connected to the inside of the stabilizing box 5 (limiting grooves should be provided on both sides of the stabilizing sleeve 1001, and limiting strips matched with the limiting grooves are fixedly connected in the stabilizing box 5 to ensure that the stabilizing sleeve 1001 does not rotate), a first transmission rod 601 is fixedly connected to a rotating drum 1002 at one end close to the stabilizing sleeve 1001, and a one-way rotating groove 1003 is provided on the outer wall of the rotating drum 1002 (the one-way rotating groove 1003 includes end grooves located at both ends of the outer wall of the rotating drum 1002 and parallel to the circumferential direction of the rotating drum 1002 and an inclined groove connected to the two end grooves), and both sides of the inner wall of the stabilizing sleeve 1001 are fixedly connected to the one-way rotating groove 10 03 is equipped with a protrusion 1004, both sides of the inner wall of the stabilizing box 5 are fixedly connected with stabilizing springs 1005 around the rotating cylinder 1002, one end of the stabilizing spring 1005 away from the stabilizing box 5 and both sides of the outer wall of the stabilizing sleeve 1001 are fixedly connected with a top plate 1006, one end of the stabilizing sleeve 1001 away from the stabilizing box 5 is fixedly connected with a stabilizing slide 1007, a supporting cylinder 1008 is slidably connected in the stabilizing slide 1007, a second pressure spring 1009 is arranged between the supporting cylinder 1008 and the stabilizing slide 1007, and one end of the supporting cylinder 1008 away from the second pressure spring 1009 is fixedly connected with a supporting pad 1010 (the supporting pad 1010 should be a rubber pad), when the driving motor 7 drives the first transmission rod 601 and When the drum 1002 rotates along the direction f in the figure, the protrusion 1004 moves along the inclined groove part in the one-way rotation groove 1003 to the side away from the center transmission box 1, thereby driving the stabilizing sleeve 1001 to move to the side away from the center transmission box 1, until the protrusion 1004 slides to the end groove part in the one-way rotation groove 1003. At this time, the driving motor 7 continues to rotate to ensure that the support pad 1010 fits the outer wall of the tower, thereby increasing the friction between the equipment and the tower and improving the stability of the equipment during detection. At the same time, the stabilizing spring 1005 close to the side of the support pad 1010 is compressed, and during the rotation of the drum 1002, a force is applied to the stabilizing sleeve 1001 toward the side of the center transmission box 1 through the top plate 1006, and then when the detection is completed. After completion, the driving motor 7 drives the first transmission rod 601 to rotate along the direction e in the figure. When the equipment resumes moving, the stabilizing sleeve 1001 is subjected to the force to drive the protrusion 1004 to enter the one-way rotation groove 1003, and move along the inclined groove part in the one-way rotation groove 1003 toward the side close to the central transmission box 1 until the protrusion 1004 slides to the end groove part in the one-way rotation groove 1003. At this time, the driving motor 7 continues to rotate to ensure that the support pad 1010 is away from the tower, thereby preventing the support pad 1010 from affecting the movement of the equipment. At the same time, the stabilizing spring 1005 on the side away from the support pad 1010 is compressed, and during the rotation of the rotating drum 1002, a force is applied to the stabilizing sleeve 1001 toward the side of the support pad 1010 through the top plate 1006.Then, when the driving motor 7 drives the first transmission rod 601 and the rotating drum 1002 to rotate again in the direction f in the figure, the stabilizing sleeve 1001 can be subjected to the force again to drive the protrusion 1004 to enter the one-way rotation groove 1003;

The dust removal assembly 11 includes a dust removal ring 1101 fixedly connected to the upper side of the stabilizing box 5 and the mounting frame 2 away from the central transmission box 1 and a dust removal box 1102 slidably connected to the dust removal ring 1101. A first arc-shaped rack 1103 is fixedly connected to one side of the upper surface of the dust removal ring 1101, a dust removal motor 1104 is fixedly connected to one side of the inner wall of the dust removal box 1102, and a dust removal gear 1105 meshing with the first arc-shaped rack 1103 is fixedly connected to the output end of the dust removal motor 1104. Dust removal chutes 1106 are provided on the upper and lower surfaces of the dust removal ring 1101, and dust removal connecting plates 1107 are fixedly connected on both sides of the outer wall of the dust removal box 1102.

When the equipment moves to the detection component 12 close to the tower weld, and the detection component 12 has not yet detected the tower, it first stops moving and stabilizes through the stabilization component 10 (that is, the drive motor 7 is controlled to drive the first transmission rod 601 to rotate along the direction f in the figure), and the dust removal motor 1104 drives the dust removal gear 1105 to rotate, thereby causing the dust removal box 1102 to rotate along the dust removal ring 1101. While the dust removal box 1102 rotates, the dust removal fan 1109 removes dust from the outer wall of the tower (because the air outlet of the dust removal fan 1109 is inclined downward, the dust removal part of the dust removal fan 1109 should be the part of the outer wall of the tower close to the detection component 12);

The detection assembly 12 includes a detection ring 1201 fixedly connected to the upper side of the stabilizing box 5 and the mounting frame 2 away from the central transmission box 1 and a detection box 1202 slidably connected to the detection ring 1201. A second arc-shaped rack 1203 is fixedly connected to one side of the upper surface of the detection ring 1201, and a detection motor 1204 is fixedly connected to one side of the inner side wall of the detection box 1202. The output end of the detection motor 1204 is fixedly connected to a detection gear 1205 meshing with the second arc-shaped rack 1203. The upper and lower surfaces of the detection ring 1201 are fixedly connected to the detection gear 1205 meshing with the second arc-shaped rack 1203. Detection chutes 1206 are provided, and detection connecting plates 1207 are fixedly connected to both sides of the outer wall of the detection box 1202. A detection pulley 1208 adapted to the detection chute 1206 is provided on the side of the detection connecting plate 1207 close to the detection chute 1206. An infrared flaw detector 1209 and an ultrasonic variable-range probe 1210 are fixedly connected to the inner wall of the detection box 1202. After the dust removal component 11 performs a certain degree of dust removal on the weld part of the outer wall of the tower that needs to be inspected, the detection motor 1204 drives the detection gear 1205 to rotate, thereby causing the detection box 1202 to rotate along the detection ring 1201. While rotating, the infrared flaw detector 1209 and the ultrasonic variable-range probe 1210 perform flaw detection on the tower weld (ultrasonic flaw detection has a higher detection accuracy for internal defects, but may be affected by factors such as material surface roughness and coating. Infrared flaw detection is not limited by these factors and can directly observe the temperature distribution on the weld surface to find potential defects. The combination of the two technologies can make up for each other's shortcomings and improve the accuracy of detection. The tower is the supporting structure of wind power generation, and its weld quality directly affects the safety performance of the entire wind power equipment. The use of two flaw detection technologies at the same time can more comprehensively and accurately find potential defects, thereby reducing The major hidden dangers of breakage, damage, expansion and rupture caused by defects are to ensure the safe operation of wind power equipment). The driving motor 7, adjusting cylinder 801, electric cylinder 608, dust removal motor 1104 and detection motor 1204 are all electrically connected to the control panel (not shown in the figure). The control panel is electrically connected with a signal receiver (not shown in the figure). The staff can send signals and receive them through the signal receiver, and transmit the signals to the control panel, thereby controlling the driving motor 7, adjusting cylinder 801, electric cylinder 608, dust removal motor 1104 and detection motor 1204. All materials should be as lightweight as possible while meeting the strength requirements.

[0035] The implementation principle of this application is: before use, the outer surface of the tower should be cleaned to ensure that there is no biological dirt, oil stains, large-area dust and other dirt on the tower surface that seriously affect the tower weld flaw detection (because the tower cleaning itself requires a long time, and the water stains remaining on the surface after cleaning will also affect the flaw detection results, so the water stains on the tower surface should be basically air-dried before using this equipment for detection);

[0036] When in use, the staff needs to first place the central transmission box 1 symmetrically along the center of the tower around the tower, and then place the mounting frame 2 between two adjacent central transmission boxes 1, align the mounting plate and the threaded grooves at the four corners of the mounting plate, and then thread them into the bolts to complete the overall assembly of the equipment. After the equipment is installed around the outside of the tower, the output end of the adjusting cylinder 801 is first moved toward the tower, driving the outer sleeve 802, the connecting block 803, the first pressure spring 804, and the rubber track 901 to move toward the tower, and then adjust the distance between the rubber track 901 and the tower, so that the equipment can adapt to more towers with different diameters. When the rubber track 901 abuts against the surface of the tower, the adjusting cylinder 801 is again Move a certain distance in the direction of the tower to compress the first pressure spring 804 (due to the special shape of the sleeve being narrow at the top and wide at the bottom, the diameter of the tower part close to the rubber track 901 is constantly changing during the climbing process of the equipment. When the equipment is climbing upward, the first pressure spring 804 is slowly released, while squeezing the connecting block 803 all the time, thereby squeezing the crawling component 9. After the equipment rises a certain distance, the adjusting cylinder 801 will drive the outer sleeve 802 to move in the direction of the tower again, and squeeze the first pressure spring 804 that has been released to a certain extent again, thereby trying to ensure good friction and stability when the equipment climbs upward). When the electric cylinder 608 drives the sliding sleeve 602 to move to the first When a ratchet 603 is meshed with the first pawl 605, when the driving motor 7 drives the first transmission rod 601 to rotate in the direction e in the figure, the first ratchet 603 drives the first pawl 605 and the first bevel gear 604 to rotate in the direction e as well. When the electric cylinder 608 drives the sliding sleeve 602 to move until the first ratchet 603 is meshed with the second pawl 607, when the driving motor 7 drives the first transmission rod 601 to rotate in the direction e in the figure, the first ratchet 603 drives the second pawl 607 and the second bevel gear 606 to rotate in the direction e as well. However, since the first bevel gear 604 and the second bevel gear 606 are both meshed with the third bevel gear 610, and the two are respectively located on both sides of the third bevel gear 610 and are symmetrically distributed, when When the first ratchet 603 drives the two to rotate in the same direction, the third bevel gear 610 rotates in the opposite direction, thereby making the equipment climb and descend. When the first bevel gear 604 rotates in the direction e in the figure, driving the third bevel gear 610 to rotate (at this time, the second bevel gear 606 idles in the direction f in the figure), the third bevel gear 610 drives the second transmission rod 609 and the fourth bevel gear 611 to rotate. The fourth bevel gear 611 drives the transmission sleeve 612, the transmission sleeve rod 614 and the sixth bevel gear 615 to rotate through the fifth bevel gear 613, thereby making the sixth bevel gear 615 drive the crawling bevel gear 904 and the active drive wheel 902 to rotate, thereby realizing the rubber crawler 901 climbing up along the tower.

[0037] When the equipment moves to the point where the detection component 12 is close to the tower weld, and the detection component 12 has not yet performed inspection and flaw detection on the tower, it first stops moving and is stabilized by the stabilization component 10 (i.e., the drive motor 7 is controlled to drive the first transmission rod 601 to rotate along the direction f in the figure). The drive motor 7 drives the first transmission rod 601 and the rotating drum 1002 to rotate along the direction f in the figure, and the protrusion 1004 moves along the inclined groove part in the one-way rotation groove 1003 toward the side away from the center transmission box 1, thereby driving the stabilization sleeve 1001 to move toward the side away from the center transmission box 1 until the protrusion 1004 slides to the end groove part in the one-way rotation groove 1003. At this time, the drive motor 7 continues to rotate to ensure that the support pad 1010 fits the outer wall of the tower, thereby increasing the friction between the equipment and the tower and improving the stability of the equipment during detection (at the same time, the stabilization spring 1005 close to the side of the support pad 1010 is compressed, and during the rotation of the rotating drum 1002, a force is applied to the stabilization sleeve 1001 through the top plate 1006 toward the center transmission box 1). The force on one side of the transmission box 1 is exerted, and then when the detection is completed, the driving motor 7 drives the first transmission rod 601 to rotate in the direction e in the figure, so that the equipment resumes moving, and the stabilizing sleeve 1001 is driven by the force to drive the protrusion 1004 to enter the one-way rotation groove 1003, and move along the inclined groove part in the one-way rotation groove 1003 to the side close to the center transmission box 1, until the protrusion 1004 slides to the end groove part in the one-way rotation groove 1003, and the driving motor 7 continues to rotate at this time to ensure that the support pad 1010 is away from the tower, and the equipment resumes moving. To prevent the support pad 1010 from affecting the movement of the device, at the same time, the stabilizing spring 1005 on the side away from the support pad 1010 is compressed, and during the rotation of the drum 1002, a force is applied to the stabilizing sleeve 1001 toward the side of the support pad 1010 through the top plate 1006, and then when the driving motor 7 drives the first transmission rod 601 and the drum 1002 to rotate again along the direction f in the figure, the stabilizing sleeve 1001 can be subjected to the force again to drive the protrusion 1004 into the one-way rotation groove 1003);

[0038] When the equipment is stable, the dust removal motor 1104 drives the dust removal gear 1105 to rotate, thereby causing the dust removal box 1102 to rotate along the dust removal ring 1101. While the dust removal box 1102 rotates, the dust removal fan 1109 removes dust from the outer wall of the tower (since the air outlet of the dust removal fan 1109 is tilted downward, the dust removal part of the dust removal fan 1109 should be the part of the outer wall of the tower close to the detection component 12);

[0039] After the dust removal component 11 has removed dust to a certain extent on the weld area on the outer wall of the tower that needs to be inspected, the detection motor 1204 drives the detection gear 1205 to rotate, and then the detection box 1202 rotates along the detection ring 1201. While the detection box 1202 rotates, the infrared flaw detector 1209 and the ultrasonic variable-range probe 1210 perform flaw detection on the tower weld.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
