DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1-7 As shown, a checking fixture for classifying wind turbine flanges includes:

[0031] The main body 1 has a fan-shaped cross section and an infrared distance measuring sensor 2 is fixedly arranged on the main body 1;

[0032] The rotating shaft 111 has a running wheel 11 fixedly disposed on its surface, and a rubber layer is fixedly disposed on the surface of the running wheel 11;

[0033] The main body 1 is provided with an inner arc surface and an outer arc surface, the infrared ranging sensor 2 is located at the central axis of the inner arc surface, and the running wheel 11 is rotatably arranged on the outer arc surface.

[0034] Specifically, Figure 7 As shown, during the inspection, the inspection fixture is installed on the wind turbine flange so that the outer arc surface of the body 1 fits against the inner ring surface of the wind turbine flange, so that the rubber layer of the walking wheel 11 contacts the inner ring surface of the wind turbine flange. During the inspection, since the cross section of the body 1 is fan-shaped and the infrared ranging sensor 2 is located at the central axis of the inner arc surface, the infrared ray of the infrared ranging sensor 2 will pass through the center of the wind turbine flange, so that the inner ring diameter of the wind turbine flange is measured by the infrared ranging sensor 2, and the data is transmitted to the control center, so that the wind turbine flange is classified according to the inner ring diameter of the wind turbine flange.

[0035] Furthermore, the driving shaft 111 rotates, thereby driving the running wheel 11 to rotate, thereby driving the main body 1 to move along the inner ring surface of the wind turbine flange through the friction between the rubber layer fixed on the surface of the running wheel 11 and the inner ring surface of the wind turbine flange, and the data measured by the infrared ranging sensor 2 are summarized, so as to perform an all-round measurement of the inner ring diameter of the wind turbine flange, and judge whether the wind turbine flange is deformed during transportation based on the data. If the data has obvious changes, it means that the wind turbine flange is deformed during transportation and needs to be replaced to ensure the connection quality and strength of each component.

[0036] In the above technology, during the inspection, the inspection fixture is installed on the wind turbine flange so that the outer arc surface of the body 1 is fitted to the inner ring surface of the wind turbine flange, so that the rubber layer of the walking wheel 11 is in contact with the inner ring surface of the wind turbine flange. During the inspection, since the cross section of the body 1 is fan-shaped and the infrared ranging sensor 2 is located at the central axis of the inner arc surface, the infrared rays of the infrared ranging sensor 2 will pass through the center of the circle of the wind turbine flange, so that the inner ring diameter of the wind turbine flange is measured by the infrared ranging sensor 2, and the rotating shaft 111 is driven to rotate, thereby driving the walking wheel 11 to rotate, so that the rubber layer fixedly set on the surface of the walking wheel 11 and the inner ring surface of the wind turbine flange are connected. The friction between the main body 1 drives the main body 1 to move along the inner ring surface of the wind turbine flange, and summarizes the data measured by the infrared ranging sensor 2, so as to measure the inner ring diameter of the wind turbine flange in all directions, and judge whether the wind turbine flange is deformed during transportation according to the data. If the data changes significantly, it means that the wind turbine flange is deformed during transportation and needs to be replaced to ensure the connection quality and strength of each component. Compared with the prior art, it has a small size, light weight, low production cost, and is easy to carry. It can not only perform classification detection, but also perform deformation detection on the wind turbine flange, effectively improving the practicality of the inspection fixture.

[0037] As a further embodiment of the present invention, it also includes symmetrically arranged clamping plates 3 which are relatively slidably arranged on the outer arc surface of the body 1.

[0038] Specifically, during the inspection, the wind turbine flange is first located between the two clamping plates 3 so that the outer arc surface of the main body 1 fits against the inner annular surface of the wind turbine flange, thereby making the rubber layer of the walking wheel 11 contact with the inner annular surface of the wind turbine flange, and the wind turbine flange is located between the two clamping plates 3, and the two clamping plates 3 are driven to move relative to each other, thereby clamping the upper and lower surfaces of the wind turbine flange.

[0039] As a further embodiment provided by the present invention, the square shell 31 is further provided on the clamping plate 3 , and a pressure sensor 36 is fixedly mounted on the inner shell wall of the square shell 31 .

[0040] Specifically, it also includes a fixing frame 35 slidably arranged in the square shell 31, a spring 37 is arranged between the fixing frame 35 and the pressure sensor 36, and a second roller 341 is rotatably arranged on the fixing frame 35. The two clamping plates 3 are driven to move relative to each other, so as to clamp the upper and lower surfaces of the wind turbine flange, so that the clamping plates 3 fit the upper and lower surfaces of the wind turbine flange, so that the second roller 341 abuts against the upper and lower surfaces of the wind turbine flange, so that the fixing frame 35 is pushed by the second roller 341 to compress the spring 37, and the initial reading of the pressure sensor 36 is obtained.

[0041] Furthermore, the driving shaft 111 rotates, thereby driving the walking wheel 11 to rotate, so that through the friction between the rubber layer fixed on the surface of the walking wheel 11 and the inner ring surface of the wind turbine flange, the main body 1 is driven to move along the inner ring surface of the wind turbine flange, thereby driving the second roller 341 to roll around the fixed axis 34 along the upper and lower surfaces of the wind turbine flange, and the data detected by the pressure sensor 36 are summarized to detect the flatness of the seam flange. If the data changes significantly, it means that the flatness of the wind turbine flange is low, which affects the tightness of the subsequent connection. The infrared ranging sensor 2 and the pressure sensor 36 can be used to perform multi-angle detection of the wind turbine flange without the need to purchase multiple detection instruments for separate detection, which effectively saves detection cost and detection time, and improves the practicality and detection efficiency of the detection tool.

[0042] As a further embodiment of the utility model, it also includes a first motor 4 arranged on the main body 1, and a bidirectional threaded rod 41 is fixedly connected to the output end of the first motor 4, and a nut plate 411 is coupled to the bidirectional threaded rod 41, and the nut plate 411 is fixedly connected to the clamping plate 3.

[0043] Specifically, the first motor 4 is driven to drive the bidirectional threaded rod 41 to rotate, thereby driving relative movement, thereby driving the two clamping plates 3 to move relative to each other, thereby clamping the upper and lower surfaces of the wind turbine flange.

[0044] As a further embodiment of the present invention, it also includes an electric push rod 33 installed on the clamping plate 3, and a limiting plate 32 is fixedly provided at the output end of the electric push rod 33.

[0045] Specifically, the limit plate 32 is arranged in an arc shape, and a first roller 321 is rotatably arranged on the limit plate 32. After the clamping of the clamp plate 3 is completed, the electric push rod 33 is started to drive the limit plate 32 to move toward the outer annular surface of the wind turbine flange, so that the first roller 321 abuts against the outer annular surface of the wind turbine flange, thereby further installing the inspection tool on the wind turbine flange. By setting the first roller 321, when the inspection tool moves, the friction between the inspection tool and the wind turbine flange is reduced, and the inspection tool can be installed according to wind turbine flanges of different widths, thereby improving the applicability of the inspection tool.

[0046] As a further embodiment of the present invention, the present invention further includes a first gear 12 fixedly disposed on the rotating shaft 111 , and a second gear 13 is meshed between two adjacent first gears 12 .

[0047] Specifically, it also includes a second motor 5 disposed on the body 1, and its output end is fixedly connected to the first gear 12. Figure 4 and Figure 6 As shown, the rotating shafts 111 are arranged in an array, and the second motor 5 is started to drive the first first gear 12 to rotate (as shown in FIG. Figure 6 As shown, the first first gear 12 is the first first gear 12 located on the leftmost side), thereby driving the second gear 13 meshing therewith to rotate, thereby driving the remaining first gears 12 to rotate, thereby driving the rotating shaft 111 to rotate, thereby driving the traveling wheel 11 to rotate, thereby driving the main body 1 to move along the inner ring surface of the wind turbine flange through the friction between the rubber layer fixed on the surface of the traveling wheel 11 and the inner ring surface of the wind turbine flange, and the second gear 13 is used to make all the first gears 12 rotate in the same direction.

[0048] Working principle: Make the outer arc surface of the body 1 fit the inner ring surface of the wind turbine flange, so that the rubber layer of the walking wheel 11 contacts the inner ring surface of the wind turbine flange, drive the first motor 4 to drive the bidirectional threaded rod 41 to rotate, thereby driving relative movement, thereby driving the two clamping plates 3 to move relative to each other, so as to clamp the upper and lower surfaces of the wind turbine flange, start the electric push rod 33 to drive the limit plate 32 to move toward the outer ring surface of the wind turbine flange, so that the first roller 321 abuts against the outer ring surface of the wind turbine flange, thereby further installing the inspection tool on the wind turbine flange, and start the second motor 5 to drive the first first gear 12 to rotate (such as Figure 6As shown, the first first gear 12 is the first first gear 12 located on the leftmost side), thereby driving the second gear 13 meshing therewith to rotate, thereby driving the remaining first gears 12 to rotate, thereby driving the rotating shaft 111 to rotate, thereby driving the walking wheel 11 to rotate, thereby driving the main body 1 to move along the inner ring surface of the wind turbine flange through the friction between the rubber layer fixedly arranged on the surface of the walking wheel 11 and the inner ring surface of the wind turbine flange. Since the cross section of the main body 1 is fan-shaped and the infrared ranging sensor 2 is located at the central axis of the inner arc surface, the infrared ray of the infrared ranging sensor 2 will pass through the center of the wind turbine flange, thereby measuring the inner ring diameter of the wind turbine flange through the infrared ranging sensor 2, and summarizing the data measured by the infrared ranging sensor 2, thereby measuring the inner ring diameter of the wind turbine flange. Perform all-round measurement, and determine whether the wind turbine flange is deformed during transportation based on the data. If the data changes significantly, it means that the wind turbine flange is deformed during transportation. The clamping plate 3 fits the upper and lower surfaces of the wind turbine flange, so that the second roller 341 abuts against the upper and lower surfaces of the wind turbine flange, so that the second roller 341 pushes the fixing frame 35 to squeeze the spring 37, and obtains the initial reading of the pressure sensor 36. The main body 1 moves along the inner annular surface of the wind turbine flange, thereby driving the second roller 341 to roll around the fixed axis 34 along the upper and lower surfaces of the wind turbine flange, and summarizes the data detected by the pressure sensor 36 to detect the flatness of the seam flange. If the data changes significantly, it means that the flatness of the wind turbine flange is low, affecting the tightness of subsequent connections.

[0049] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
