Description

Technical Field

[0001] The present invention relates to the field of auxiliary installation tooling for a wind tower control platform, and in particular to a tooling for controlling the positioning size of an outer platform. Background Art

[0002] With the promotion and application of offshore wind power generation technology, major wind turbine manufacturers have increased their investment in the research and development of offshore wind towers, and the proportion of offshore wind towers has increased year by year. In addition, due to the fierce competition in the wind power industry, major manufacturers must consider how to achieve the required structural strength of wind towers at a lower cost while developing new models. The design of wind tower access platforms is also changing with each passing day. The design of offshore wind tower access platforms is more difficult than that of conventional land-based wind towers. During the manufacturing process, higher assembly requirements are required. Due to the limited assembly conditions at sea and the lack of mechanization and automation equipment compared to onshore, the tower factory's production precision requirements are increased. The original process route design was based on marking the arc length and then locating the column position. Due to the larger diameter of offshore wind towers, workers face great difficulties in measuring arc length, assembly, and welding. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of the present invention.

[0013] Figure 2 for Figure 1 Magnified view of area A in center. DETAILED DESCRIPTION

[0014] like Figure 1-2 As shown, a tool for controlling the positioning size of the outer platform includes a steel pipe lifting electropermanent magnet 7 adsorbed on the upper end of the tower 1, a lifting ear is fixed on the upper end of the steel pipe lifting electropermanent magnet 7, a long plate 8 is fixed on the upper end of the steel pipe lifting electropermanent magnet 7 along its length, and three slide grooves 9 are opened on the upper end of the long plate 8 along its length. A rectangular frame 2 is provided above the steel pipe lifting electropermanent magnet 7, and the four corners of the end face of the frame 2 facing the tower 1 are fixed with support rods 3 perpendicular to them. The support rods 3 are connected to the frame 2 by diagonal braces 4, and a fixing plate 5 is fixed on the end of the support rod 3 away from the frame 2. 5 is detachably fixed with a mounting plate 6, the fixed plate 5 and the mounting plate 6 are connected by connecting bolts, and slide bars 10 are slidably provided in the slide grooves 9 on the left and right sides, and a space is provided between the slide bar 10 and the bottom of the slide groove 9 in which the slide bar 10 is located to allow the slide bar 10 to move, the slide bar 10 is fixedly connected to the frame 2, and a slide plate 11 is slidably provided in the middle slide groove 9, and the middle part of the front and rear ends of the frame 2 are threadedly connected with an adjusting bolt 12, and the lower end of the adjusting bolt 12 is rotatably connected to the slide bar 10. The four support rods 3 on the frame 2 are the same as the length, horizontal spacing and vertical spacing of the mounting legs on the control outer platform.

[0015] When the present invention is used, the steel pipe lifting electropermanent magnet 7 is adsorbed on the upper end of the tower 1. Because the two adsorption surfaces of the steel pipe lifting electropermanent magnet 7 have a certain angle, the two adsorption surfaces of the steel pipe lifting electropermanent magnet 7 can adsorb the two side parts of the upper end of the tower 1. Therefore, after the steel pipe lifting electropermanent magnet 7 is adsorbed on the upper end of the tower 1, it can be ensured to be parallel to the axis of the tower 1, pushing the frame 2 to slide on the long plate 8. When the control outer platform installation position is reached, the adjusting bolt 12 is screwed to make the frame 2 close to the tower 1. When the mounting plate 6 contacts the outer edge of the tower 1, the mounting plate 6 is welded to the outer edge of the tower 1, and then the connecting bolts connecting the fixing plate 5 and the mounting plate 6 are removed, and the steel pipe lifting electropermanent magnet 7 and the frame 2 are lifted away from the tower 1. Because the four support rods 3 on the frame 2 are the same as the length, horizontal spacing and vertical spacing of the mounting legs on the control outer platform, when the control outer platform is installed, the legs on the control outer platform can be properly connected to the mounting plate 6, thereby increasing the installation efficiency and accuracy of the control outer platform. The tooling does not require welding and fixing, is easy to load and unload, and is easy to operate. It solves the problem of positioning the external platform and the tooling can be reused.

[0016] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
