Under the sun, the temperature of the metal surface is very high, and the adsorption head is in contact with it for a long time, which has a greater impact on its service life.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1 to 6 As shown, the present invention discloses a magnetic adsorption walking device, which includes: a device frame 10, two sets of main moving mechanisms 20 and two sets of auxiliary moving mechanisms 30. The two sets of main moving mechanisms 20 are symmetrically installed on both sides of the device frame 10, and the two sets of auxiliary moving mechanisms 30 are placed between the two sets of main moving mechanisms 20. It is best that the four sets of mechanisms are symmetrical about the device frame 10. And along the connecting direction of the two sets of main moving mechanisms 20, the auxiliary moving mechanisms 30 are arranged in two rows. The device frame 10 is designed as a frame structure, which is conducive to reducing the weight. The device frame 10 is used to carry functional devices, such as a painting device, a welding device, a drilling device, etc.

[0027] The main moving mechanism 20 includes a mounting frame 21, a circulating transmission assembly, a driving member 23 and a plurality of first magnetic members 24. The mounting frame 21 is rotatably connected to the device frame 10. Specifically, a rotating member is provided on the mounting frame 21, and the rotating member includes a limit plate 211 and a rotating shaft. The rotating shaft includes an integrally formed limit portion 213 and two rotating portions 214. The rotating portion 214 is located at both ends of the limit portion 213, and the diameter of the rotating portion 214 is smaller than the diameter of the limit portion 213. After such an arrangement, a step surface can be formed between the rotating portion 214 and the limit portion 213. The limit plate 211 and the limit portion 213 are locked by bolts or directly welded. Two shaft seats 11 are provided on both sides of the device frame 10. A limit opening 13 and a shaft hole 12 adapted to the rotating portion 214 are provided on the shaft seat 11, and the limit opening 13 is connected to the shaft hole 12. The two shaft seats 11 arranged on the same side have their shaft holes 12 arranged coaxially, the rotating part 214 corresponds to the shaft seat 11 one by one, and the rotating part 214 is rotatably connected in the shaft hole 12, requiring that the rotating part 214 can only enter and exit in the axial direction of the shaft hole 12, and cannot escape from the shaft hole 12 in the circumferential direction of the shaft hole 12. In addition, the shaft hole 12 is limitedly matched with the limiting part 213, that is, the step surface will abut the outer edge of the shaft hole 12 to prevent the limiting part 213 from passing through the shaft hole 12. The shaft seat 11 limits the rotating shaft at both ends, so that the rotating part can only rotate in place.

[0028] The limit plate 211 is placed in the limit opening 13, and the thickness of the limit plate 211 is less than the width W of the limit opening 13, and the limit plate 211 can have a certain range of movement in the limit opening 13. The limit plate 211 is connected to the mounting frame 21. In particular, it is required that one of the walls of the limit opening 13 is parallel to the device frame 10, so that one of the extreme positions of the rotation of the mounting frame 21 is parallel to the device frame 10, because during use, it is rare for the magnetic metal surface to change from a convex arc to a concave arc, and it is usually a constant convex arc (such as the outer tube wall) or a concave arc (such as the inner tube wall), and making one of the extreme positions of the main moving mechanism 20 parallel to the device frame 10 can avoid excessive activity of the main moving mechanism 20, so that the device can maintain better stability when a sudden wind blows at high altitude.

[0029] The circulating transmission assembly and the driving member 23 are both arranged on the mounting frame 21. The circulating transmission assembly includes a conveyor belt 221, a driving wheel 222 and at least one driven wheel 223. The driving wheel 222 and the driven wheel 223 are arranged in a row at equal intervals and are rotatably connected to the mounting frame 21. The conveyor belt 221 connects the driving wheel 222 and the driven wheel 223, and the driving member 23 is connected to the driving wheel 222. The driving member 23 is a motor. The arrangement of multiple driven wheels 223 can support the conveyor belt 221. In addition, in order to adjust the tightness of the conveyor belt 221, an adjusting shaft 215, two oblong holes 216, two limiting holes 217, two adjusting screws 218 and two adjusting nuts 219 are provided on the mounting frame 21. The oblong holes 216, the limiting holes 217, the adjusting screws 218 and the adjusting nuts 219 correspond to each other. The limiting hole 217 is connected to the oblong hole 216, and the two ends of the adjusting shaft 215 are respectively slidably connected to an oblong hole 216. One end of the adjusting screw 218 is threadedly connected to the adjusting nut 219, and the other end passes through the limiting hole 217 and is threadedly connected to the adjusting shaft 215. The adjusting shaft 215 is provided with a screw hole adapted to the adjusting screw 218. The driven wheel 223 farthest from the driving wheel 222 is rotatably connected to the adjusting shaft 215. The tightness of the conveyor belt 221 can be adjusted by rotating the adjusting nut 219.

[0030] The first magnetic members 24 are evenly arranged outside the transmission belt, and the driving member 23 drives the circulating transmission assembly to operate, thereby driving the first magnetic members 24 to move in a circular manner. In order to facilitate the installation of the first magnetic member 24, a plurality of mounting components 25 are provided on the conveyor belt 221. The mounting components 25 include a mounting plate 251 and two clamping plates 252. The two clamping plates 252 are placed at the edge positions on both sides of the inner surface of the conveyor belt 221, and the clamping plates 252 do not interfere with the driving wheel 222 and the driven wheel 223. The mounting plate 251 is placed outside the conveyor belt 221. The mounting plate 251 is bolted to the clamping plates 252, and then clamped and fixed on the conveyor belt 221. In addition, in order to prevent the mounting component 25 from sliding relative to the conveyor belt 221, the mounting plate 251 and / or the clamping plates 252 are required to be limitedly matched with the conveyor belt 221. It can be that nail holes are set on the transmission belt, and nails are set on the mounting plate 251 and / or the clamping plates 252. The mounting component 25 is further locked by inserting the nails into the nail holes. The first magnetic member 24 is fixed to the mounting plate 251 by screws. The first magnetic member 24 can be a magnet. In order to increase the friction between the first magnetic member 24 and the magnetic metal surface, reduce noise, and prevent the first magnetic member 24 from scratching the magnetic metal surface, each contact surface of the first magnetic member 24 is covered with a first set 26, and the first set 26 is made of non-magnetic isolation material, such as PU. Alternatively, a number of hollows are provided on the first set 26 so that the magnetic force can absorb the magnetic metal surface. The first set 26 can be directly bolted to the mounting seat.

[0031] The auxiliary moving mechanism 30 is adjustable relative to the device frame 10. Specifically, the auxiliary moving mechanism 30 includes a support frame 31 and two auxiliary wheels 32. The connection direction of the two auxiliary wheels 32 is parallel to the conveying direction of the cyclic conveying assembly. A slideway 14 and at least one locking screw 15 for locking the support frame 31 are provided on the device frame 10. One end of the support frame 31 is slidably connected to the slideway 14. The locking screw 15 is threadedly connected to the device frame 10, and the locking screw 15 can extend into the slideway 14 and abut the support frame 31. The support frame 31 is locked by tightening the locking screw 15. The auxiliary wheel 32 is rotatably connected to the other end of the support frame 31. Of course, the auxiliary moving mechanism 30 can also be fixed relative to the device frame 10. In particular, the auxiliary wheel 32 is made of magnetic material, or a plurality of second magnetic suction members are evenly arranged on the outer periphery of the auxiliary wheel 32, or a magnetic ring made of magnetic material is fixed on the outer periphery of the auxiliary wheel 32. The auxiliary wheel 32 can also be adsorbed on the magnetic metal surface, further improving the adhesion between the device and the magnetic metal surface. In addition, in order to prevent the magnetic hard material on the auxiliary wheel 32 from scratching the working surface, a second set 33 for buffering is wrapped on the outside of the auxiliary wheel 32. The second set 33 is made of non-magnetic isolation material, or a plurality of hollows are provided on the second set 33.

[0032] The auxiliary moving mechanism 30 can act as a fulcrum on the device. Because the working surface of the device is uncertain, the magnetic parts cannot be adapted to each working surface. The contact surface of the magnetic parts is usually set as a plane, that is, the magnetic parts are generally in the shape of a cuboid and do not need to be customized. For example, when the working surface is a curved surface, the contact surface of the magnetic parts cannot completely adhere to the curved surface. When working at high altitudes, the wind will blow the device from time to time. If the wind is strong, the device as a whole will swing. After the auxiliary moving mechanism 30 is set, the amplitude of the device swing can be effectively reduced, so that the functional device can be better used and the construction quality can be guaranteed.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
