The positioning device can ensure that the hybrid tower ring piece is accurately installed at the predetermined position, avoid installation errors, and significantly reduce the time for manual adjustment, accelerate the production process, and improve production efficiency by quickly and accurately positioning the hybrid tower ring piece.

[0003] In the prior art, generally, a branch platform is arranged outside the central positioning disk, several positioning screw holes are arranged on the branch platform, screws are screwed into the positioning screw holes, and a positioning plate is sleeved on the screws and fixed by a matching nut to position hybrid tower ring pieces of different sizes. However, in this way, the positioning plate is fixed at the upper end of the positioning screw hole through the screw and the nut, and the positioning screw holes are arranged at intervals, resulting in that the positioning plate can only be fixed at the preset positioning screw hole positions, cannot continuously adjust the position, and the fixed positioning screw hole positions may not be applicable to the installation requirements of all sizes of hybrid tower ring pieces, thus limiting the adaptability of the equipment. Summary of the Utility Model

[0004] In view of this, aiming at the deficiencies of the prior art, the utility model provides a positioning device for a wind power hybrid tower ring piece, which can not only position the hybrid tower ring piece through the positioning parts arranged on the branch platform, but also move the slide plate inside the branch platform to drive the positioning parts to continuously move along the branch platform, so as to enable the positioning parts to adjust the appropriate positions according to hybrid tower ring pieces of different sizes and improve the adaptability of the equipment.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is: a positioning device for a wind power hybrid tower ring piece, which includes a central positioning disk, several support columns are arranged below the central positioning disk, a base is jointly connected below the support columns, several branch platforms are detachably arranged outside the central positioning disk, a fixing component for fixing the branch platforms is arranged on the central positioning disk, and a positioning component is jointly arranged on the central positioning disk and the branch platforms.

[0006] As a further improvement of the present utility model, the positioning assembly includes sliding grooves opened on the central positioning disk and the branch platform.

However, the protection scope of the present utility model is not limited to the following embodiments only. In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0022] Such as Figure 1 、 2, as shown in FIGS. 3 and 4, a positioning device for a wind power hybrid tower ring plate includes a central positioning disc 101. Below the central positioning disc 101, there are several support columns 102. The lower ends of the support columns 102 are jointly connected to a base 103. Several branch platforms 104 are detachably arranged outside the central positioning disc 101. A fixing component for fixing the branch platforms 104 is arranged on the central positioning disc 101. The fixing component includes several groups of lugs 304 arranged on the outer wall of the positioning central disc. Each group of lugs 304 consists of two groove plates. At the position corresponding to the groove plates on the outer wall of one end of the branch platform 104 close to the positioning central disc, there are pin posts 305. Through the cooperation of the lugs 304 and the pin posts 305, it is convenient to disassemble the branch platforms 104, enabling the branch platforms 104 to be quickly disassembled and reinstalled, improving the flexibility of the equipment. A positioning component is jointly arranged on the central positioning disc 101 and the branch platforms 104.

[0023] As Figure 1 , 2 , as shown in FIGS. 4 and 5, the positioning component includes chutes opened on the central positioning disc 101 and the branch platforms 104. Inside the chutes, there are sliding plates 201 slidably arranged. At one end of each sliding plate 201 close to the central positioning disc 101, there are guide rods 202. At the other end of each sliding plate 201 away from the central positioning plate, there are positioning members. At the upper end of the central positioning disc 101, there is a driving component for driving the sliding plates 201 to move. The driving component includes a first rotating column 203 arranged in the middle of the upper end of the central positioning disc 101. At the upper end of the first rotating column 203, there is a first gear 204. At the right end of the central positioning disc 101, there is a second rotating column 205. At the upper end of the second rotating column 205, there is a second gear 206 meshing with the first gear 204. At the lower end of the central positioning disc 101, there is a fixed motor 207. The output end of the motor 207 is connected to the second rotating column 205 through a coupling. On the first gear 204, there is a guiding groove 208 adapted to the guide rods 202.

[0024] As Figure 1 , 3 , as shown in FIG. 6, the positioning member includes a right-angle plate 301 arranged at the upper end of the sliding plate 201. In the center of the side surface of the right-angle plate 301, there is a through hole. Outside the through hole, there is a positioning sleeve 302. Inside the positioning sleeve 302, there is an adjusting screw 303 connected by threads.

[0025] As Figure 1 , as shown in FIG. 7, at one end of each branch platform 104 away from the outer wall of the positioning central disc, there is a bearing plate 105. On each bearing plate 105, there is a support screw 106. The end of the branch platform 104 is sleeved on the support screw 106, and a limit nut 107 is arranged on the support screw 106 below the branch platform 104. By arranging the support screw 106, the branch platform 104 can be supported assistantly, improving the stability of the equipment.

[0026] In use, first place the central positioning disc 101 at the hoisting site of the mixing tower. Fix the bearing plate 105 and the branch platform 104 together through the support screw 106 and the limit nut 107, and snap the inner end of the branch platform 104 onto the hanging ear 304. Then start the motor 207. The motor 207 drives the second rotating column 205 to rotate. The second rotating column 205 drives the second gear 206 to rotate. The second gear 206 causes the first gear 204 to rotate. The rotation of the first gear 204 makes the guide rod 202 slide along the guide groove 208. As the guide rod 202 slides along the guide groove 208, the sliding plate 201 can move along the sliding groove. The movement of the sliding plate 201 drives the right-angle plate 301 to move, so as to adjust the position of the right-angle plate 301. Then rotate the adjusting screw 303 so that its end moves to the inner diameter position of the ring piece. Then use the on-site hoisting equipment to successively hoist the mixing tower ring piece to the branch platform 104 along the end of the adjusting screw 303, so as to position and install the mixing tower ring piece.

[0027] According to another embodiment of the present invention, as Figure 1 , 2 shown, a rubber end 306 is provided at the end of the adjusting screw 303. The rubber material is relatively soft. The rubber end 306 can reduce the direct contact between the adjusting screw 303 and the mixing tower ring piece and reduce wear.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solutions of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
