Description

Technical Field

[0001] The invention relates to an integrated tool for assembling and positioning offshore wind tower welding parts, and also relates to a method for using the same. Background Art

[0002] Traditional onshore wind towers have simple structures of welded parts, simple welding nodes with the cylinder, low positioning tolerances, and no spatial relationship between them. When positioning and assembling welded parts, you only need to use spline tooling to mark and tape measure to locate the welded parts. No special and complex tooling is required, and the operation is simple.

[0003] However, the structural design of offshore wind towers is completely different from that of onshore wind towers. The welded parts have complex structures, large sizes and heavy weights, high positioning dimensional accuracy requirements, and strict relative dimensional relationships between welded parts.

[0004] The existing integrated tooling for positioning offshore wind towers has the following problems: (1) the positioning accuracy of the size of the welded parts is not high; (2) the spatial dimensions between the welded parts cannot be controlled to ensure the relative position between them.

[0005] It is unable to meet the complex structure of offshore wind tower welded parts and the strict requirements on the size of welded parts. Summary of the invention

[0006] The present invention aims to solve the above-mentioned technical problems and proposes an integrated tooling for assembling and positioning offshore wind tower welding parts, which can achieve the goal of welding part positioning, reduce the difficulty of welding part positioning operation, ensure the one-time success of welding part positioning, eliminate rework after positioning failure, and thus improve production efficiency.

[0007] An integrated tool for assembling and positioning offshore wind tower welding parts according to the present invention comprises the following:

[0008] Backing template, used to guide and specify the positioning position of welded parts;

[0009] The cylinder connection adjustment mechanism is located on the back of the backing plate, and is used to adjust the radial position of the backing plate;

[0010] The flange connection adjustment mechanism is arranged in front of the backrest template, and the flange connection adjustment mechanism is used to adjust the axial position of the backrest template.

[0011] Specifically, at least two groups of positioning holes are provided on the surface of the backrest template.

[0012] Specifically, the spacing between the two groups of positioning holes is 2650 mm to 2655 mm.

[0013] Specifically, the flange connection adjustment mechanism includes a screw and a twist head, the screw and the twist head are connected, and one end of the screw passes through the front of the backrest template and extends to the back of the backrest template and extends to the outside.

[0014] Specifically, at least four screws are provided, and the screws are symmetrically distributed in front of the backrest sample.

[0015] Specifically, the cylinder connection adjustment mechanism includes an adjusting bolt and a bolt mounting seat. The adjusting bolt is arranged on the back of the backrest template and is screwed to the bolt mounting seat.

[0016] Specifically, the backrest template is an aluminum alloy backrest template.

[0017] Specifically, the backrest template is arc-shaped or square-shaped.

[0018] Specifically, the backrest model is also provided with a frame.

[0019] The beneficial effects of the present invention are: 1. This structure provides a target orientation for the welding position of the welded parts through the backing template, guides the assembly operation of the welded parts, avoids the individual positioning of a single welded part, and then repeatedly measures and adjusts the size relationship between the two; 2. This structure adjusts the gap between the two backing templates and the cylinder through the cylinder connection adjustment mechanism, so that the centers of the four welded parts are arranged at the center position of the cylinder, avoiding possible eccentricity; the flange connection adjustment mechanism is used to adjust the axial position of the backing template, which improves the accuracy of the positioning of the welded parts, achieves successful positioning in one time, avoids rework and repair, improves product quality and production efficiency, shortens the production cycle, and also reduces the labor intensity of workers.
