Technical Field

[0001] The utility model relates to the technical field of wind power tower processing, in particular to a positioning device for wind power tower processing. Background Art

[0002] The wind turbine tower is the tower pole of wind power generation. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the set. The production process of the wind turbine tower is generally as follows: CNC cutting machine unloads, thick plates need to be beveled, and the plate rolling machine rolls the plate into shape, spot welding, positioning, and confirmation before welding the inner and outer longitudinal seams. After the roundness inspection, if there is a problem, a secondary rounding is performed. After the single-section cylinder is welded, the hydraulic group is used to assemble the roller frame for spot welding, the inner and outer circumferential seams are welded, and the straightness and other tolerances are checked. After the flange is welded, non-destructive testing and flatness inspection of the weld are performed, sandblasting, painting, internal parts installation and finished product inspection are completed, and then it is transported to the installation site.

[0003] After searching the publication (announcement) number: CN217750179U, a positioning device for wind power tower processing is disclosed, including a positioning base and two U-shaped positioning frames, the two U-shaped positioning frames are arranged on the top of the positioning base and are symmetrically distributed, the inner side of the U-shaped positioning frames are fixedly connected with arc-shaped bottom supports, cylinders are embedded on both sides of the U-shaped positioning frames, the output end of the cylinder extends to the inner side of the U-shaped positioning frame and is fixedly connected with an arc-shaped clamping plate, the inner side of the positioning base is rotatably connected with a bidirectional screw rod, and a driving mechanism is arranged on the left side of the positioning base. The utility model hoists the cylinder body on the inner side of the U-shaped positioning frame and is fixed by the arc-shaped clamping plate, the driving mechanism rotates the bidirectional screw rod, and the two internal threaded connectors are close to each other to drive the U-shaped positioning frame to move, so that the two fixed cylinder bodies are close to each other for docking, and the docking is convenient and fast, which improves the docking efficiency.

[0004] Although the above scheme allows the two fixed cylinders to be close to each other for docking, the docking is convenient and fast, and the docking efficiency is improved, but during the welding operation, it is inconvenient to flip the support of the cylinder for welding, and the cylinder needs to be re-positioned and clamped, resulting in low welding efficiency. For this reason, we propose a positioning device for wind power tower processing. Utility Model Content

When the first driving motor 203 drives the threaded shaft 201 to rotate, the moving member 202 can move along the threaded shaft 201.

[0029] like Figure 3 As shown, the fixed adjustment unit 3 includes an L-shaped fixed seat 301 installed on the side wall of the moving member 202, a second drive motor 302 installed on the L-shaped fixed seat 301, a rotating disk 303 installed at the output end of the second drive motor 302, an electric push cylinder 304 installed on the side wall of the rotating disk 303, and a fixed member 305 arranged at the telescopic end of the electric push cylinder 304. During the telescopic process of the electric push cylinder 304, the fixed member 305 can move left and right synchronously.

[0030] like Figure 1 As shown, the mobile unit 1 includes a workbench 101, a base 102 installed at the bottom of the workbench 101, and a traveling wheel 103 installed at the bottom of the base 102. The arrangement of the traveling wheel 103 facilitates the movement of the entire device.

[0031] like Figure 2 As shown, the mobile unit 1 further includes a traveling handrail 104 installed on the side wall of the workbench 101. The arrangement of the traveling handrail 104 facilitates the control of the traveling direction.

[0032] like Figure 4 As shown, the support member 204 includes a hydraulic cylinder 2041 installed on the top of the moving member 202, and an arc-shaped support plate 2042 installed at the telescopic end of the hydraulic cylinder 2041. During the telescopic process of the hydraulic cylinder 2041, the arc-shaped support plate 2042 moves synchronously.

[0033] like Figure 5 As shown, the fixing member 305 includes a mounting fixing block 3051 installed at the telescopic end of the electric push cylinder 304, an electric telescopic rod 3052 installed on the side wall of the mounting fixing block 3051, and an arc-shaped supporting plate 3053 installed at the telescopic end of the electric telescopic rod 3052. During the telescopic process of the electric telescopic rod 3052, the arc-shaped supporting plate 3053 can be driven to move synchronously.

[0034] When the two cylinders need to be welded at the ends, the cylinders are first placed on the two arc-shaped support plates 2042 respectively. Subsequently, the telescopic end of the electric push cylinder 304 is extended so that the installation fixed block 3051 penetrates into the interior of the cylinder. At this time, the telescopic end of the hydraulic cylinder 2041 is extended and retracted so that the fixed block 3051 stops after being located on the central axis. At this time, the telescopic end of the electric telescopic rod 3052 is extended so that the arc-shaped supporting plate 3053 fits against the inner wall of the cylinder. Subsequently, the first drive motor 203 drives the threaded shaft 201 to rotate. Since the threaded shaft 201 is provided with threads with opposite rotation directions at both ends, the two moving parts 202 can drive the two cylinders to move in a direction close to each other until the ends of the two cylinders touch and stop. At this time, the positioning of the two cylinders before welding is completed. Example

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, a positioning device for processing a wind power tower includes a moving unit 1, an adjusting unit 2 arranged above the moving unit 1, and a fixed adjusting unit 3 arranged on the side of the adjusting unit 2;

The setting of the limiting washer 205 prevents the moving part 202 from contacting and colliding with the side wall of the fixed groove during the movement of the threaded shaft 201.

[0042] like Figure 5 As shown, the fixing member 305 includes a mounting fixing block 3051 installed at the telescopic end of the electric push cylinder 304, an electric telescopic rod 3052 installed on the side wall of the mounting fixing block 3051, and an arc-shaped supporting plate 3053 installed at the telescopic end of the electric telescopic rod 3052. During the telescopic process of the electric telescopic rod 3052, the arc-shaped supporting plate 3053 can be driven to move synchronously.

[0043] After the positioning of the two cylinders before welding is completed, welding can be carried out along the contact parts of the ends of the two cylinders. After the welding exceeds half of the circumference, the telescopic end of the hydraulic cylinder 2041 contracts, and the telescopic end of the electric telescopic rod 3052 extends again, so that the arc-shaped supporting plate 3053 supports the inner wall of the cylinder. At this time, the second drive motor 302 drives the rotating disk 303 to rotate, and the rotating disk 303 drives the cylinder to rotate through the arc-shaped supporting plate 3053, so that the original support for the cylinder is flipped to the top, so that welding can be carried out conveniently; the repositioning and clamping of the cylinder is avoided, and the welding efficiency is improved.
