Description

Technical Field

[0001] The present application relates to the field of building construction technology, and in particular to a wind turbine tower arc segment mold. Background Art

[0002] As a clean energy source, wind power generation has experienced rapid development amidst the domestic energy conservation and emission reduction efforts. With the gradual development of onshore wind farms in recent years, wind tower heights have increased, and new steel-concrete composite towers with greater rigidity have gradually become mainstream. To improve construction efficiency, concrete tower sections are often prefabricated in factories and assembled on-site. For ease of transportation, they are often manufactured in separate pieces. Traditional horizontal mold systems facilitate construction operations such as reinforcing and pouring concrete, but they often result in large surface areas and low construction efficiency. This makes it difficult to ensure the quality and appearance of the concrete segments on the outside, impacting the overall safety and aesthetics of the steel-concrete tower.

[0003] Currently, the curved tube segment molds for wind turbine towers mainly use vertical molds. Vertical molds can overcome the problems existing in the horizontal molds in the manufacturing process of tower segments. However, the clamping and opening actions of the vertical molds in the existing technology require the help of a crane, which not only affects the efficiency and effect of clamping and opening, but also easily causes collision deformation of the mold, and there is also a safety risk of the mold falling and injuring people.

[0004] Regarding the above-mentioned related technologies, other tools are needed for closing and opening the vertical mold, and the degree of automation is low, which leads to low efficiency in closing and opening the mold. Summary of the Invention

The locking member 101 is connected to the side wall of the end of the inner mold 3 away from the curved bottom plate 2. A lifting member 8 is installed on the curved bottom plate 2, and the lifting member 8 is connected to the driving member 4. The driving member 4 is connected to two auxiliary members 7, and the two auxiliary members 7 are symmetrically installed on the side wall of the inner plate away from the curved bottom plate 2.

[0056] Cement is poured between the curved bottom plate 2, the inner mold 3, and the side mold 9.

The auxiliary part 7 includes a sliding rod 71, and the two ends of the sliding rod 71 are respectively fixedly connected to the upper and lower inner walls of the mounting groove 31. A slider 72 is sleeved and slidably connected to the sliding rod 71. The side walls at both ends of the slider 72 are tightly fitted with the inner wall of the mounting groove 31. The fixed end of the second telescopic rod 73 is fixedly connected to the top wall of the mounting groove 31. The end of the fixed end of the second telescopic rod 73 away from the movable end is connected to the end of the fixed end of the electric hydraulic rod 41 close to the movable end. The movable end of the second telescopic rod 73 is fixedly connected to the top wall of the slider 72, and one end of the auxiliary rod 74 is hinged on the side wall of the end of the slider 72 away from the bottom wall of the mounting groove 31. The other end of the auxiliary rod 74 is hinged on the base 1, and the auxiliary rod 74 passes through the center of the inner wall of the curved bottom plate 2 in the length direction of the projection of the mounting base 1.

The sliding of the slider 72 drives the auxiliary rod 74 to move, so that the auxiliary rod 74 tilts. When the inner mold 3 abuts the inner wall of the curved bottom plate 2, the inner mold 3 is supported, thereby improving the stability of the inner mold 3 and improving the casting quality of the cement pipe segment.

[0063] Reference Figure 2 and Figure 3 The locking member 101 includes a locking block 1011, which abuts against the side wall of the inner mold 3 away from the arc-shaped bottom plate 2.

The bolt 1012 is rotatably connected to the side wall of the inner mold 3 away from the arc-shaped bottom plate 2.

[0064] When the side form 9 is in contact with the inner form 3 and the outer form 5, the bolt 1012 is passed through the locking block 1011, and the nut 1013 tightens the bolt 1012 to ensure the tightness of the side wall and improve the casting quality of the cement pipe segment.

[0066] The contraction of the electric hydraulic rod 41 drives the inner mold 3 to contract, and the electric hydraulic rod 41 drives the first telescopic rod 62 to contract. When the first telescopic rod 62 contracts to a predetermined position, the hydraulic fluid in the electric hydraulic rod 41 enters the third telescopic rod 81 through the overflow valve 83, and the third telescopic rod 81 extends to drive the lifting plate 82 to move. The movement of the lifting plate 82 lifts the condensed arc tube segment, making it more convenient for the arc tube to be demolded.

[0067] The implementation principle of the curved tube segment mold of a wind turbine tower in the embodiment of the present application is as follows: cement is poured between the curved bottom plate 2, the inner mold 3, and the side mold 9. When the cement solidifies, the locking part 101 is removed, and the two side molds 9 are opened to separate the outer mold 5 and the inner mold 3. The driving part 4 drives the inner mold 3 to move in the direction away from the curved bottom plate 2. The movement of the driving part 4 drives the transmission part 6 to move, and the movement of the transmission part 6 drives the outer mold 5 to move toward one end away from the curved bottom plate 2. When the outer mold 5 and the inner mold 3 move to the predetermined position, the lifting assembly moves to push the clean cement tube segment upward, making it easier to remove the cement tube segment from the mold, increasing the automation of the mold, and improving the efficiency of mold closing and opening. The auxiliary part 7 is used to support the inner plate to ensure the stability of the inner plate.
