technical field

The present application relates to the technical field of wind power, and in particular, to a mold for segmenting a tower.

Background technique

As the power generation efficiency of the wind turbine increases, the wind turbine blades are getting longer and longer, and the height and section size of the matching wind turbine tower are also increasing. Due to the high cost and difficult transportation of steel structure towers, it is difficult to meet the construction requirements of large cross-section and high towers. Precast concrete towers, on the other hand, have attracted widespread attention because of their ability to economically build large wind turbines. Due to the limitations of transportation conditions and prefabricated processing conditions, a single large-section tower is often assembled from multiple segments on site. Then, the assembled single towers are hoisted from bottom to top in sequence, and finally a complete concrete tower is constructed.

In the concrete tower structure disclosed in the related art, due to the large cross-sectional size of the tower and the limitation of transportation and prefabricated processing equipment, it needs to be prefabricated and assembled on-site in a segmented manner, that is, the tower is divided into several annular tower sections, And each tower section is made of slices and prefabricated assembly. The existing tower-segmented molds mainly adopt the vertical casting method, and the lengths and dimensions of the formed tower-segments are limited, and the scope of use is limited.

Therefore, there is an urgent need for a new mold for tower slicing.

Detailed ways

Features and exemplary embodiments of various aspects of the present application are described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to those skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present application by illustrating examples of the present application. In the drawings and the following description, at least some well-known structures and techniques are not shown in order to avoid unnecessarily obscuring the present application; and, the dimensions of some structures may be exaggerated for clarity. Furthermore, the features, structures or characteristics described below may be combined in any suitable manner in one or more embodiments.

The orientation words appearing in the following description are all the directions shown in the drawings, and do not limit the specific structure of the mold for the tower segment of the present application. In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it may be a fixed connection or a detachable connection, or Connected integrally; either directly or indirectly. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

In the concrete tower structure disclosed in the related art, due to the large section size of the tower and the limitation of transportation and prefabricated processing equipment, it needs to be prefabricated and assembled on site in a segmented manner, that is, the tower is divided into several annular tower sections, and each Each tower section is made of pieces and prefabricated.

As shown in FIG. 1 , there are existing molds for forming tower segments, which mainly adopt the vertical casting method. The molds generally include an inner mold 1a, an outer mold 1b, a top mold 1c, a bottom mold 1d and a mold located inside the inner mold 1a. The supporting system 1e, the inner mold 1a, the outer mold 1b, the top mold 1c and the bottom mold 1d together form a vertical pouring space 1f, which is used for pouring the slurry of materials such as concrete to form the tower segment. This type of vertical casting mold is mainly used for tower segments with shorter dimensions to be formed. When the size of the tower segment to be formed is too long, if the above-mentioned mold is used for casting, the pouring space 1f required for pouring will be too high, which will cause unavoidable difficulties for cranes, pouring equipment and manual operations. . Further, when the heights of the inner mold 1a and the outer mold 1b are too high, the accuracy of the side close to the top mold 1c is difficult to control. The inner mold 1a establishes a connection to control the accuracy, which is easy to cause deviation of the outer mold 1b, which is not conducive to the accuracy control of the formed tower cylinder.

When it needs to be installed, it can be extended through the telescopic device 26 to drive the side formwork 22 to move to other parts of the formwork, and then reach a predetermined position and fasten it. The extension or contraction of the retractable device 26 drives the side formwork 22 to approach or move away from the base 11 so as to be docked or disassembled with the end formwork assembly 30 . The installation and removal of the side formwork 22 can be easily controlled with high efficiency. and convenient.

As shown in FIG. 12, another manner of installation and removal of the end die assembly 30 is provided. The retractable device 36 is used to retract and drive the end template 32 away from other parts of the mold, thereby completing the removal of the opposite end template 32 . The telescopic device 36 can be a hydraulic jack device, which is fixed on the fourth support part 37, and the fourth support part 37 is fixed on the end mold bottom support part 38, so as to pass the fourth support part 37, the end mold bottom The support portion 38 is used to fix the retractable device 36 . When it needs to be installed, it can be extended through the telescopic device 36 to drive the end formwork 32 to move to other parts of the formwork, and then it can reach a predetermined position and fasten it. The extension or contraction of the telescopic device 36 drives the end formwork 32 to approach or move away from the base 11 so as to be docked or disassembled with the side formwork assembly 20 , and the installation and removal of the end formwork 32 can be easily controlled with high efficiency. and convenient.

As shown in FIG. 12 , the installation order of the end mold assembly 30 and the side mold assembly 20 is not limited. The end mold assembly 30 can be installed first and then the side mold assembly 20 can be installed, or the side mold assembly 20 can be installed first and then the side mold assembly 20 can be installed. Reinstall the end die assembly 30. In the mold provided in the embodiment of the present application, since the side mold assembly 20, the bottom mold assembly 10, etc. are all positioned based on the bottom mold assembly 10, the positioning is accurate, the standard is unique, and each mold assembly is separated from the bottom mold assembly. If the part 10 is relatively close, both in terms of precision and the overall rigidity of the mold, there is sufficient guarantee that the casting space will not be too high due to the excessively long dimension of the mold in the length direction X of the bottom mold assembly 10 . Tower segments with larger lengths can be cast and formed, so that the mold is not limited by the length dimensions of the tower segments to be formed, and the application range is wider. Moreover, in the process of pouring, the outer surface of the tower segment is pre-cast, which can avoid the influence of factors such as bubbles generated on the outer surface during the pouring process, so that the appearance of the outer surface of the formed tower segment is better. .

While the application has been described with reference to the preferred embodiments, various modifications may be made and equivalents may be substituted for parts thereof without departing from the scope of the application. In particular, as long as there is no structural conflict, each technical feature mentioned in each embodiment can be combined in any manner. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
