Description

Technical Field

[0001] The utility model relates to a forming structure for the casting construction of a wind power foundation, belonging to the technical field of wind power construction. Background Art

[0002] During the construction of a wind power turbine, a circular foundation needs to be cast on a square foundation poured on the ground. Since the circular foundation has a curvature, a split cylinder mold needs to be used to form a casting space.

[0003] The existing cylinder mold for a circular foundation can be seen in Chinese Patent Publication No. CN210597331U. Although a forming structure for the casting construction of a circular foundation with four arc-shaped parts can form a circular foundation cylinder mold through hinge connection, after the cylinder mold is placed, there is a problem that it is not easy to limit its position at the center of the square foundation. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a forming structure for the casting construction of a wind power foundation.

[0005] The utility model is achieved through the following technical solutions.

[0006] A forming structure for the casting construction of a wind power foundation provided by the utility model includes:

[0007] A square foundation cast and solidified in the ground;

[0008] Four split cylinder molds that overlap each other. The outer tops of the cylinder molds are tightened by hoop clamps, and a casting space for casting and solidifying a circular foundation of a wind power turbine is formed in the middle of the four split cylinder molds.

[0009] It further includes a limiting mechanism. The limiting mechanism is symmetrically distributed in a circumferential array of four and corresponds to the overlapping parts of the cylinder molds. The cylinder molds are tightly pressed and limited at the center position of the square foundation through the limiting mechanism.

[0010] The limiting mechanism includes: a plate seat fixed on the ground;

[0011] A telescopic rod is hinged to the plate seat, and an arc-shaped clamping plate is hinged to the telescopic rod. The clamping plate corresponds to the overlapping parts of the cylinder molds.

[0012] The plate seat is fixed in the ground through ground claws.

[0013] Through holes are provided at the four corners of the plate seat and ground claws are installed through the through holes. The four ground claws penetrate the through holes of the plate seat and are driven into the ground for fixation.

[0014] The beneficial effects of the present utility model are as follows: After the four-piece cylinder mold is overlapped with each other, the top is tightened by a hoop. The four-piece cylinder mold forms a pouring space in the middle and is placed at the center of the square foundation. The four limiting mechanisms tightly abut and limit the bottom of the four-piece cylinder mold, solving the problem that it is difficult to limit the position of the cylinder mold at the center of the square foundation after placement.

[0019] The technical solution of the present utility model will be further described below, but the scope of protection is not limited thereto.

[0020] As Figures 1 to 3 shown.

[0021] A forming method for the circular foundation of a wind power generator of the present application includes:

[0022] After excavating downward on the ground 1, a square foundation 2 is formed by pouring and curing concrete. Four-piece cylinder molds 3 that overlap each other are installed on the square foundation 2. A pouring space for pouring and curing the circular foundation 4 of the wind power generator is formed in the middle of the four-piece cylinder molds 3. The outer tops of the four-piece cylinder molds 3 are tightened by a hoop 5.

[0023] The outer bottoms of the four-piece cylinder molds 3 are radially limited and tightly abutted by a limiting mechanism 6. The cylinder molds 3 are tightly abutted and limited by the limiting mechanism 6 and are located at the center of the square foundation 2. Concrete is poured into the pouring space in the middle of the four-piece cylinder molds 3 to form the circular foundation 4 of the wind power generator. As Figure 1 shown, a forming structure for the construction of a wind power foundation pouring is presented.

[0024] Then the four-piece cylinder molds 3 are moved up to the top of the formed circular foundation 4 of the wind power generator. Two hoops 5 are installed outside the four-piece cylinder molds 3 and are tightened up and down; at this time, the limiting mechanism 6 supports the axial bottom surfaces of the four-piece cylinder molds 3. As Figure 2 , Figure 3As shown, at this time, concrete is poured into the pouring space in the middle of the four-petal cylinder mold 3 to continue to raise the circular foundation 4 of the wind turbine, and the pouring is repeated several times to reach the required height of the circular foundation 4 of the wind turbine.

[0025] A forming structure for pouring construction of a wind power foundation in the present application includes:

[0026] A square foundation 2 is cast and solidified in the ground 1;

[0027] The four-petal cylinder mold 3 is overlapped with each other, and the outer top of the cylinder mold 3 is clamped by a hoop 5. The middle of the four-petal cylinder mold 3 forms a casting space for the circular foundation 4 of the wind turbine to be cast and solidified;

[0028] The limiting mechanism 6 is symmetrically distributed in four circular arrays and corresponds to the overlapping parts of the drum molds 3. The drum mold 3 is tightly limited at the center position of the square foundation 2 by the limiting mechanism 6.

[0029] After the four-petal cylinder mold 3 is overlapped with each other, the top is tightened by the clamp 5. The four-petal cylinder mold 3 forms a casting space in the middle and is placed in the center of the square foundation 2. Four limiting mechanisms 6 limit the bottom of the four-petal cylinder mold 3, which solves the problem that the cylinder mold is not easy to be limited in the center of the square foundation after being placed. When pouring concrete in the later stage, the four-petal cylinder mold 3 is not easy to be displaced, which ensures the load transfer between the circular foundation 4 and the square foundation 2 of the wind turbine in the later stage.

[0030] The limiting mechanism 6 comprises: a plate seat 61 fixed to the ground 1, with through holes at four corners of the plate seat 61 and ground claws 62 installed therethrough, and four ground claws 62 penetrate through the through holes of the plate seat 61 and are driven into the ground 1 for fixing;

[0031] The plate seat 61 is hinged with a telescopic rod 63 , and the telescopic rod 63 is hinged with an arc-shaped clamping plate 64 . The clamping plate 64 corresponds to the overlapping position of the cylinder mold 3 .

[0032] The telescopic rod 63 is telescopically pressed against the clamping plate 64, so that the clamping plate 64 has two functions: the first function: when the cylinder mold 3 contacts the square foundation 2 to cast the circular foundation 4 of the wind turbine, the overlapped parts of the cylinder molds 3 are clamped and pressed tightly to limit the position; the second function: when the cylinder mold 3 moves upward, the axial bottom surface of the cylinder mold 3 is supported and dragged.

[0033] Figure 3 The hoop 5 for tightening the lower part of the drum mold 3 is hidden in the figure, so as to better show that the clamping plate 64 supports and drags the axial bottom surface of the drum mold 3.
