[0029] The specific implementation of the prefabricated component mold for a wind power hybrid tower transition ring provided by this utility model will be further described with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 As shown, a precast component mold for a wind power hybrid tower transition ring includes a bottom mold 1, an outer mold 2, and an inner mold 3. The outer mold 2 is movably mounted on top of the bottom mold 1 via several sliding components; the inner mold 3 is disposed within the cylindrical cavity enclosed by the outer mold 2 and has a gap between it and the inner wall of the outer mold 2, forming an annular casting mold cavity with a top opening.

[0031] like Figure 3 As shown, the bottom mold 1 includes a base 104 with a square cross-section, an annular connecting seat 103 located in the middle of the top of the base 104, and several outer mold top locks 101; the base 104 is provided with four slide rail groups that are equally spaced around the annular connecting seat 103; two of the slide rail groups are distributed along one diagonal of the base 104, and the other two slide rail groups are distributed along the other diagonal of the base 104, and the two sub-slide rails 102 of each slide rail group are symmetrically arranged on the left and right sides of the opposite diagonal.

[0032] Preferably, the inner ring plate 1031 of the annular connecting seat 103 is provided with a plurality of first positioning holes 1032 for fixing the inner mold 3 in the circumferential direction.

[0033] To ensure a tight connection between the outer mold 2 and the bottom mold 1 when they are closed, the base 104 is provided with a plurality of fixing holes 1041 at equal intervals along the circumference near the periphery of the annular connecting seat 103. The fixing holes 1041 are arranged in a circle and can be arranged in multiple rings. However, the distance from the fixing hole 1041 closest to the annular connecting seat 103 to the annular connecting seat 103 is equal to the thickness of the outer mold 2. The outer mold top lock 101 is installed on the base 104 through the fixing holes 1041. When closing the mold, the outer mold 2 is slid to a position close to the outer wall of the annular connecting seat 103 and the outer mold top lock 101 is fixed at the position closest to the annular connecting seat 103, which holds the outer mold 2 in place. When opening the mold, the outer mold top lock 101 is removed and the outer mold 2 can be disengaged from the annular connecting seat 103 along the slide rail assembly.

[0034] like Figure 4 As shown, the outer mold 2 is a cylindrical mold structure formed by splicing four unit outer molds 202. During installation, each unit outer mold 202 corresponds to one of the slide rail groups.

Each of the second inner molds 303 has a structural clearance 3032 along its height on either its left or right side. The third inner mold 304 has connecting plates 3042 along its height on both its left and right sides. During installation, the two second inner molds 303 are respectively located on the left and right sides of the third inner mold 304, with the sides having the structural clearance 3032, and are bolted to the connecting plates 3042 of the third inner mold 304 to form a first connecting section.

[0038] To counteract the expansion force generated by the concrete during the curing stage, a central column assembly 5 is provided in the middle of the cavity of the inner mold 3; correspondingly, a tie rod fixing seat 305 is provided in the middle of the inner wall of the three first inner molds 302, the two second inner molds 303, and the third inner mold 304. The tie rod fixing seat 305 is fixed to the outer wall of the central column assembly 5 by tie rods 501, such as... Figure 2 As shown.

[0039] like Figure 9 As shown, in order to improve the accuracy between the inner and outer molds during mold closing, a plurality of opening adjustment devices 4 are provided at equal intervals along the circumferential direction on the opening side of the annular mold cavity. Specifically, the opening adjustment device 4 includes a first fixing seat 401 and a second fixing seat 402. The first fixing seat 401 is disposed on the top of the inner mold 3 (first inner mold 302, second inner mold 303 and third inner mold 304); the second fixing seat 402 is disposed on the top of the outer mold 2 (four unit outer molds 202); and an adjustment rod 403 is disposed between each group of the first fixing seat 401 and the second fixing seat 402. The first fixing base 401 and the second fixing base 402 have the same structure, both including a mounting plate and two channel steels with opposite grooves vertically arranged on the top of the mounting plate; a gap is provided between the two channel steels for the adjustment rod 403 to pass through; the two channel steels of the first fixing base 401 are symmetrically provided with limiting grooves; the two channel steels of the second fixing base 402 are horizontally provided with limiting baffles 4021 between the two outer side walls near the first fixing base 401 and between the two outer side walls away from the first fixing base 401; it is worth noting that the top of the limiting baffle 4021 is flush with the bottom of the limiting groove, thereby ensuring that the adjustment rod 403 is always in a horizontal state when it is installed and adjusted.

[0040] like Figure 10As shown, one end of the adjusting rod 403 is provided with a connector 4031, and the other end is threaded with an inner nut 4032 and an outer nut 4033. The inner nut 4032 is located on the side of the second fixed seat 402 closer to the first fixed seat 401; the outer nut 4033 is located on the side of the second fixed seat 402 away from the first fixed seat 401; the connector 4031 is slidably connected to the limiting groove of the first fixed seat 401. In use, the connector 4031 is first slidably installed in the limiting groove of the first fixed seat 401, and the relative positions of the inner nut 4032 and the outer nut 4033 on the adjusting rod 403 are adjusted, that is, the distance between the connector 4031 and the inner nut 4032 of the adjusting rod 403 is adjusted and tightened with the outer nut 4033 to match the width of the annular mold cavity opening side, ensuring mold closing accuracy.

[0041] To facilitate worker movement, an outwardly extending outer mold platform 201 is provided on the top of the outer mold 2 along its radial direction. The bottom of the outer mold platform 201 is provided with several ribs 2012 connected to the outer side wall of the outer mold 2. The base 104 is provided with a ladder 2011 connected to the outer mold platform 201. An inwardly extending inner mold platform 301 is provided in the mold cavity of the inner mold 3 along its radial direction. Preferably, guardrails are also installed on the outer edges of the outer mold platform 201 and the inner mold platform 301.

[0042] The specific working principle of this utility model is as follows:

[0043] When closing the mold, first, install the inner mold on the first positioning hole of the bottom mold, connect the tie rods between the middle column group and the tie rod fixing seats of the inner mold, and tighten all connecting bolts; then, slide the outer mold to the position close to the outer wall of the annular connecting seat and tighten all bolts, then lock it with the outer mold top lock and firmly hold the outer mold and the annular connecting seat of the bottom mold together; finally, pour and cure the component.

[0044] When opening the mold, first, open the tie rods between the central column assembly and the tie rod fixing seats of the inner mold, remove all the fastening bolts of the outer mold, and remove the top lock of the outer mold. Push all four unit outer molds along the sub-slide rails away from the bottom mold to complete the demolding of the outer mold. Then, remove all the fastening bolts of the inner mold, and use the lifting device to lift the inner mold out of the forming component to complete the demolding of the inner mold.

[0045] This utility model has a reasonable structure and is easy to demold. Compared with traditional transition ring molds, it ensures the accuracy of mold closing while effectively offsetting the expansion force generated during concrete curing.
