It should be noted that, the tower section of thick bamboo of the lower extreme of concrete tower section of thick bamboo has great volume, makes for polylith arc tower section of thick bamboo usually, and the concatenation assembly is whole annular concrete tower section of thick bamboo, correspondingly, when making arc tower section of thick bamboo, can use curved roof mould body 410.

According to an embodiment of the present invention, as shown in fig. 18, a base 500 for a concrete tower mold for a wind turbine includes: the base body 510 and the group of multiunit embedded parts, be formed with two fixed punch combination 511 that the interval set up on the base body 510, every group fixed punch combination 511 includes a plurality of fixed holes 512 that the circumference interval set up, and multiunit embedded part group establishes on one side surface of base body 510 and is located between two fixed punch combination 511, and every group embedded part group includes at least one built-in fitting 521.

When the concrete tower drum of the wind driven generator is manufactured, the outer mold 100 and the inner mold 200 of the concrete tower drum of the wind driven generator need to be installed on the base 500, and the fixing hole group 511 is arranged on the base body 510, so that the outer mold 100 and the inner mold 200 of the concrete tower drum of the wind driven generator can be conveniently assembled on the base 500, and the outer mold 100 and the inner mold 200 of the concrete tower drum of the wind driven generator can be stably assembled with the base 500.

Specifically, as shown in fig. 18 to 21, two positioning portions 523 are provided on the embedded part 521, and two positioning holes 524 matched with the positioning portions 523 are formed on the base body 510. Thus, the embedded part 521 can be efficiently positioned on the base body 510 by the fitting of the positioning portion 523 and the positioning hole 524.

Alternatively, a positioning hole 524 is formed on the base body 510, and a positioning portion 523 extends downward from the bottom surface of the embedment 521 and is adapted to extend into the positioning hole 524. As shown in fig. 20 and 21, the positioning portion 523 is provided at the lower end of the embedded part 521, and accordingly, as shown in fig. 18 and 19, the positioning hole 524 adapted to the positioning portion 523 is provided on the base body 510, so that the embedded part 521 can be quickly inserted into the base body 510 through the positioning portion 523 at the lower end of the embedded part 521, and the assembly efficiency is improved.

In order to enhance the reliability of the connection between the embedded part 521 and the base body 510, the embedded part 521 may be further magnetically attracted to the base body 510. Thereby, the stability of the connection between the embedment 521 and the base body 510 can be further enhanced. For example, a magnet may be provided at the bottom end of the embedded part 521, so that the embedded part 521 is positioned on the base body 510 by the positioning portion 523, and the embedded part 521 can be more stably fixed to the base body 510 in conjunction with the attraction of the magnet at the lower end of the embedded part 521. Of course, the embedded part 521 may also be a magnet, and in this case, the base body 510 may be an iron part or the like suitable for being adsorbed to the embedded part 521.

As shown in fig. 18 to 21, positioning holes 524 are formed on the base body 510, and positioning portions 523 extend downward from the bottom surface of the embedment 521 and are adapted to extend into the positioning holes 524. Therefore, the positioning part 523 at the bottom end of the embedded part 521 is inserted into the positioning hole 524, so that efficient and stable positioning between the embedded part 521 and the base body 510 can be realized. For example, as shown in fig. 18 and 19, two sets of fixing hole groups 511 are provided at intervals on the base body 510, and embedment positioning holes 524 are provided between the fixing hole groups 511, and as shown in fig. 20 and 21, positioning portions 523 are correspondingly provided at the bottom ends of the embedments 521, whereby the embedments 521 can be quickly and stably assembled to the base body 510 by inserting the positioning portions 523 into the positioning holes 524, thereby improving the assembling and disassembling efficiency of the embedments 521.

Further, as shown in fig. 18 to 21, the positioning portions 523 and the positioning holes 524 are respectively two, each positioning portion 523 is formed in a cylindrical shape, and each positioning hole 524 is a circular hole. Therefore, the cylindrical positioning part 523 can be inserted into the corresponding circular positioning hole 524, so that the positioning part 530 and the base body 510 can be fixedly assembled, and the processing is simple and the cost is low. Specifically, as shown in fig. 20 and 21, the positioning portion 523 is divided into two sections in the vertical direction, the upper end of the positioning portion 523 is a cylindrical end, and the lower end of the positioning portion 523 is a truncated cone-shaped end. Therefore, when the positioning portion 523 is assembled with the positioning hole 524, the truncated cone-shaped end at the lower end of the positioning portion 523 can perform the functions of quick positioning and guiding, and the positioning portion 523 and the positioning hole 524 can be conveniently fixed in an inserting manner, as shown in fig. 18 and 19, the positioning hole 524 is a cylindrical hole, and the aperture of the positioning hole 524 can be equal to or slightly larger than the outer diameter of the cylindrical end at the upper end of the positioning portion 523.

The cross-sectional shape of the positioning hole 524 may be non-circular. For example, in the cross section of the positioning hole 524, the inner surface of the positioning hole 524 may include at least one straight line segment, and the shape of the positioning portion 523 is matched with the shape of the positioning hole 524. Therefore, the embedded part 521 can be prevented from rotating and being fixed insecurely, the inner surface of the cross section of the positioning hole 524 is provided with a straight line segment, the positioning part 523 and the positioning hole 524 are in a shape matched with the positioning hole 524, and the positioning part 523 of the embedded part 521 can be effectively prevented from rotating. For example, the positioning hole 524 may be provided as a semicircular hole, the positioning part 523 may be correspondingly provided as a semicylindrical hole, or the like. Of course, the positioning hole 524 may also be an elliptical hole, an oblong hole, a polygonal hole, or the like.

Preferably, as shown in fig. 20 and 21, the embedment 521 is configured such that the cross-sectional area is gradually reduced toward a direction away from the base body 510. Therefore, when the casting of the concrete tower tube piece is completed, the demolding between the embedded part 521 and the tower tube or the tower tube piece is facilitated, and meanwhile, the positioning between the top of the embedded part 521 and the prestressed pipe is facilitated.

Specifically, when the concrete tower bobbin sheet of the wind turbine is manufactured, the prestressed pipe needs to be embedded in the concrete tower bobbin sheet, the bottom end of the prestressed pipe is fixedly assembled with the embedded part 521, as shown in fig. 20 and 21, the cross-sectional area of the embedded part 521 increases gradually from top to bottom, and the body of the embedded part 521 includes three parts: the uppermost end of the prestressed pipe is formed into a guide part 5211 which is formed by a truncated cone and a cylinder with a smaller cross section area, when the embedded part 521 is assembled with the prestressed pipe, the guide part 5211 can play a role of guiding, the lower end of the guide part 5211 is connected with a cylindrical installation part 5212, the prestressed pipe is assembled and connected on the installation part 5212 through the guiding effect of the guide part 5211, the outer diameter of the installation part 5212 is smaller than the inner diameter of the prestressed pipeline, therefore, the prestressed pipe is installed on the embedded part 521 under the guiding effect of the guide part 5211, and efficient assembly between the prestressed pipe and the embedded part 521 is realized. The lower end of the mounting portion 5212 is connected with a truncated cone-shaped fixing portion 5213, and the truncated cone-shaped fixing portion 5213 is formed into a truncated cone shape gradually increasing from top to bottom, so that the embedded part 521 can be smoothly separated from the tower tube piece during demolding.

As shown in fig. 22 and 23, the base 500 further includes: a positioning member 530, the positioning member 530 being disposed on a side surface of the base body 510. Therefore, by arranging the positioning piece 530 on the base body 510, a corresponding positioning hole can be formed at the bottom of the concrete tower bobbin piece, so that the positioning assembly during the assembly of the concrete tower bobbin piece is facilitated. For example, as shown in fig. 22 and 23, the bottom end of the positioning member 530 is provided with two positioning portions 523 having the same shape as the positioning portions 523 of the embedded part 521, as shown in fig. 18 and 19, the base body 510 is provided with positioning member 530 assembling holes corresponding to the positioning portions 523, so that the positioning member 530 can be inserted and fixed on the base body 510 through the positioning portions 523 at the lower end of the positioning member 530, and the bottom end of the positioning member 530 can be provided with a magnet, so that when the positioning portions 523 of the positioning member 530 are inserted and connected with the positioning member 530 assembling holes, the positioning member 530 can be more stably assembled on the base body 510 through the magnet at the bottom end of the positioning member 530.

Alternatively, as shown in fig. 22 and 23, the positioning member 530 is configured to have a cross-sectional area gradually decreasing in a direction away from the base body 510. Therefore, on one hand, after the casting of the concrete tower bobbin pipe sheet of the wind driven generator is completed, the demolding between the positioning piece 530 and the prefabricated member is facilitated; on the other hand, the bottom of the prepared concrete tower tube piece of the wind driven generator can form a positioning hole with the cross sectional area gradually increasing from top to bottom, so that the positioning of a tower tube or a tower tube piece during installation is facilitated. As shown in fig. 22 and 23, the positioning member 530 includes an upper truncated cone-shaped main body 531 and a lower truncated cone-shaped base 532, and two positioning portions 523 are provided on the truncated cone-shaped base 532.

Preferably, as shown in fig. 18, the base body 510 is formed by splicing at least two sub-bases 500. Thereby, the transportation and assembly of the base body 510 are facilitated. It should be noted that, the cross-sectional area of the tower tube piece at the bottom end of the tower cylinder of the wind turbine generator is relatively large, and accordingly, the base body 510 has a relatively large area, which is inconvenient for transportation and installation. The base body 510 is formed by splicing a plurality of pieces, so that the base body 510 can be conveniently transported and installed.

As shown in fig. 18, the two fixing hole groups 511 are formed in an arc shape. The two fixing hole groups 511 may be formed in an arc shape (as shown in fig. 18), thereby facilitating the assembly fixation between the base body 510 and the outer mold 100 and the arc-shaped inner mold 200 of the arc-shaped wind turbine concrete tower mold. It should be noted that, in the manufacturing process of the wind driven generator tower tube piece, the cross-sectional area of the tower tube piece at the lower part of the wind driven generator tower is large, and a plurality of arc-shaped tower tube pieces can be assembled into a whole annular tower tube piece after being cast by adopting an arc-shaped mold.

Similar to the internal mold lifting lug 280, as shown in fig. 8 to 11, a plurality of external mold lifting lugs 160 are provided on the second external mold reinforcing ribs 172, so that when the external mold 100 is lifted by the external mold lifting lugs 160, the external mold lifting lugs 160 apply external force to the external mold body 110 through the second external mold reinforcing ribs 172, and the external force acting area is the area of the connecting surface of the second external mold reinforcing ribs 172 and the external mold body 110, and the area of the connecting surface is large, so that the concentration degree of the external force applied to the external mold body 110 can be reduced, the deformation of the external mold body 110 can be reduced, and the dimensional accuracy of the external mold 100 can be ensured.

For example, in the example of fig. 9 and 10, 8 first outer die lifting lugs 161 and 8 second outer die lifting lugs 162,8 first outer die lifting lugs 161 and 8 second outer die lifting lugs 162 are correspondingly and vertically arranged on the second outer die reinforcing rib 172 at intervals along the circumferential direction of the outer die body 110, specifically, 8 first outer die lifting lugs 161 are uniformly and vertically arranged at intervals along the circumferential direction of the outer die body 110 on the upper portion of the outer die body 110, similarly, 8 second outer die lifting lugs 162 are uniformly and vertically arranged at intervals along the circumferential direction of the outer die body 110 on the lower portion of the outer die body 110, and 8 first outer die lifting lugs 161 and 8 second outer die lifting lugs 162 are respectively and vertically corresponding to each other, so that when the outer die 100 is lifted by the outer die lifting lugs 160 by using the lifting device, the outer die 100 is better stressed, and the position of the outer die 100 is easily adjusted, thereby improving the lifting efficiency.

According to an embodiment of the present invention, as shown in fig. 2 to 14, the inner mold 200 and the outer mold 100 are respectively formed by sequentially splicing a plurality of sub molds in a circumferential direction. For example, in the example of fig. 2-4, the inner mold body 210 is formed by sequentially assembling 4 inner mold sub-mold bodies 201 along the circumferential direction, and the inner mold sub-mold bodies 201 may be connected to each other by a plurality of inner mold bolts 203 and a plurality of inner mold pin shafts 202. The size of the inner mold sub-mold body 201 is smaller than that of the inner mold body 210, and therefore, the inner mold sub-mold body 201 is more convenient to manufacture and transport, and cost can be saved. Meanwhile, the 16 lifting lugs shown in fig. 2 and 3 are equally distributed on the 4 inner die sub-die bodies 201, that is, 4 inner die lifting lugs 280 are arranged on each inner die sub-die body 201, so that the lifting of the single inner die sub-die body 201 can be facilitated. Of course, the number of the inner mold sub-mold bodies 201 can be set according to actual requirements, so that the manufacturing and transportation requirements can be better met.

The inner mold bolt 203 is used for connecting the inner mold sub-mold bodies 201, and the structural strength and the tightness of the inner mold 200 are guaranteed. The inner mold pin shaft 202 can be a taper pin and is used for positioning the inner mold bodies 201 mutually, the taper pin is good in self-locking performance, high in positioning accuracy and convenient to install, and the influence of repeated dismounting on the positioning accuracy is small, so that the relative position accuracy between the inner mold bodies 201 is guaranteed.

For example, as shown in fig. 2-4 and 7, the inner mold body 210 is substantially arc-shaped, and the wind turbine concrete tower tube pieces are cast from a mold having the inner mold 200, and then two concrete tower tube pieces are butted to form a single wind turbine concrete tower tube.

Alternatively, the cross-section of the inner mold body 210 may be substantially arc-shaped, and the corresponding central angle of the arc-shaped may be specifically set according to actual requirements, for example, may be less than 180 ° (e.g., 90 °, 120 °, etc.), and of course, may be equal to or greater than 180 °, so as to better meet the actual requirements. For example, as shown in fig. 2-4, two pieces of wind turbine concrete tower pipe cast from a mold having an inner mold 200 may be butted together to form a single wind turbine concrete tower pipe.

Moreover, the inner mold body 210 may be a hollow cylinder longitudinally cut along its central axis according to actual requirements, and at this time, a mold with the inner mold 200 is cast to form a tower tube piece, and a tower tube formed by assembling a plurality of tower tube pieces is a hollow cylinder structure.

Moreover, the concrete tower drum of the wind driven generator is generally a large hollow cone structure, the cross section of the tower drum is annular, the size of the cross section of the lower part of the tower drum is larger, and the size of the cross section of the upper part of the tower drum is smaller. Due to the limitations of transportation conditions and prefabrication conditions of the concrete tower tube of the wind turbine, a single concrete tower tube with a large cross section may be assembled from a plurality of concrete tower tube pieces with smaller sizes, wherein each concrete tower tube piece is cast by a mold, whereby the cross section of the mold may be set to be substantially arc-shaped, and at this time, the cross section of the outer mold 100 is also substantially arc-shaped. Such as the outer mold 100 of arcuate cross-section shown in fig. 2-4, in which case the concrete duct piece may be cast from the mold with the outer mold 100.

In correspondence with the inner mold 200, as shown in fig. 9-11, the cross section of the outer mold body 110 is generally arc-shaped, and the central angle corresponding to the arc-shape can be specifically set according to actual requirements, for example, it can be less than 180 ° (e.g., 90 °, 120 °, etc.), and of course, it can also be equal to or greater than 180 °, so as to better meet the actual requirements. For example, as shown in fig. 9-11, a single aerogenerator concrete tower may be constructed by butt-jointing two aerogenerator concrete tower pipe pieces cast from a mold having an outer mold 100.

As in the example of fig. 9-14, similar to the inner mold 200, the outer mold 100 body is formed by sequentially assembling 4 outer mold sub-mold bodies 101 in the circumferential direction, and the outer mold sub-mold bodies 101 may be connected by a plurality of outer mold bolts 103 and a plurality of outer mold pins 102. Since the outer mold body 101 is small in size, the outer mold body 101 is more convenient to manufacture and transport, and thus, cost can be saved. Meanwhile, the 16 lifting lugs shown in fig. 9 are equally distributed on the 4 outer die mould bodies 101, that is, 4 outer die lifting lugs 160 are arranged on each outer die mould body 101, so that the lifting of a single outer die mould body 101 can be facilitated. Of course, the number of the outer mold die bodies 101 can be set according to actual requirements, so that the manufacturing and transportation requirements can be better met.

Therefore, according to the mold 700 for the concrete tower tube sheet of the wind driven generator, the base 500, the inner mold 200, the outer mold 100, the top plate mold 400 and the cavity defined by the first side plate mold 301 and the second side plate mold 302 are used for casting the concrete tower tube of the wind driven generator, wherein the first side plate mold 301 and the second side plate mold 302 are pivotally connected with the inner mold 200, when casting is completed, the first side plate mold 301 and the second side plate mold 302 can be rotated to the inner side of the inner mold 200 after the outer mold 100 is disassembled, demolding operation is performed on the prefabricated member, workload in the demolding operation process is simplified, and working efficiency is improved.
