Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Examples:

as shown in fig. 1, the concrete section of the mixing tower in the prior art is a schematic diagram, the whole concrete section is cylindrical, the concrete section is located at the bottom of the wind driven generator during installation, the radial dimension is about 7m, the radial dimension and the vertical dimension are consistent, and the concrete section cannot be formed at one time due to the fact that the height of the concrete section is large, the concrete section is formed by stacking multiple layers, each layer comprises two semicircular concrete sections 43, the two concrete sections 43 encircle to form a circle, and the butt joint surfaces between the upper layer and the lower layer are arranged in a staggered manner, so that the stress born by each concrete section 43 is dispersed, and the stress is uniform. The concrete sections with the same vertical dimension belong to straight line sections of wind power mixing towers, in the wind power mixing towers, the situation that the vertical dimension difference is very small, namely, the inclined line sections of the wind power mixing towers are of a conical structure, but the radius difference between the upper part and the lower part is very small, the radius difference between the upper part and the lower part is only about a few centimeters, the dimension difference is very small for the concrete sections with the radial dimension of about 7m, the fine adjustment on the dimension of the module of the wind power mixing tower is only needed during production, and generally, a machine tool is adopted to perform milling operation on the related module frame so as to manufacture the radial difference between the upper part and the lower part of the module.

The aluminum mould for wind power mixed tower construction in the embodiment is used for producing the concrete section 43 in fig. 1, and in order to facilitate construction and improve construction efficiency, the aluminum mould is usually arranged beside site selection of a wind driven generator, and after the concrete section 43 is produced, the concrete section is directly transported to a selected position for construction. And another important advantage of this embodiment is that the equipment, dismantle very conveniently, after the construction of one place finishes, can transfer to next construction place immediately after dismantling rapidly, can not take place deformation in the transfer process, and overall structure adopts the aluminum product to make moreover, and weight is lighter, has alleviateed workman's intensity of labour greatly, has also improved the efficiency of dismantling, equipment, but recycle after abandoning does not use, can not produce industrial waste. The specific structure of this embodiment is described in detail below.

As shown in fig. 2, a schematic cross-sectional view of the whole embodiment mainly includes the following parts: the concrete pouring device comprises an outer die 1, an inner die 3, a base 5, a back edge mechanism 7, an inner die supporting mechanism 6 and a construction platform 41, wherein the outer die 1 and the inner die 3 are of two circular structures which are concentrically arranged, a space formed between the two circular structures is an annular concrete pouring area 4, and the base 5 is arranged at the bottom of the concrete pouring area 4 and is in sealing contact with the outer die 1 and the inner die 3 to jointly form the concrete pouring area 4. In this way, during construction, after the outer mold 1, the inner mold 3 and the base 5 are installed and fixed in place, concrete is poured into the concrete pouring area 4, the outer mold 1 is removed after the concrete is shaped, and the shaped concrete segment 43 stays on the base 5, so that the concrete segment 43 required in fig. 1 can be obtained. The back edge mechanism 7 comprises two parts, wherein one part is a hoop which is arranged outside the outer mold 1 and is used for fastening the outer mold 1 to prevent the outer mold from swelling outwards due to the pressure of concrete, the other part is a hoop which is arranged inside the inner mold 3 and is used for fastening the inner mold 3 to prevent the inner mold from being sunken inwards due to the pressure of the concrete, and the back edge mechanism 7 of the two parts is basically consistent in structure. The inner mold supporting mechanism 6 is arranged in the inner mold 3 and is used for supporting the back ridge mechanism 7 of the inner mold 3 and simultaneously can provide a foundation for the construction of the construction platform 41.

For a single manufacturer, the concrete segments 43 produced by the single manufacturer are usually the same specification, here, the concrete segments 43 with the outer diameter of 6980mm and the wall thickness of 320mm are taken as an example, because the radial dimension of the concrete segments reaches 7m, the radial dimension of the whole outer mold 1 and the inner mold 3 is very large, the embodiment equally divides the whole outer mold 1 into 56 outer mold modules 2 with the same structure, the inner mold 3 is equally divided into 50 inner mold modules 30 with the same structure, and the outer mold modules 2 and the inner mold modules 30 are all made of aluminum materials, so that the outer mold 1 with the larger volume and the larger weight and the inner mold 3 are divided into single modules with the smaller volume and the smaller weight, and the assembly, the disassembly and the transportation processes are very convenient. In addition, during production, the inner die 3 does not need to be disassembled and assembled after being fixed, and can be recycled only by disassembling the outer die 1, so that the cost is greatly reduced, and the efficiency is improved. Fig. 16 is a schematic cross-sectional view of a single outer mold module 2 and a single inner mold module 30, which are basically similar in structure, and each comprises an arc-shaped section 8 and two connecting sections 9 on both sides, wherein only the two connecting sections 9 of the outer mold module 2 face outward, and the two connecting sections 9 of the inner mold module 30 face inward, so that the central angle corresponding to the arc-shaped section 8 on the single outer mold module 2 is 360 ° divided by the number of the outer mold modules 2, and the central angle corresponding to the arc-shaped section 8 on the inner mold module 30 is 360 ° divided by the number of the inner mold modules 30, and in addition, the planes where all the connecting sections 9 are located pass through the centers of the outer mold 1 and the inner mold 3.

As for the structure of the connecting piece 11, as shown in fig. 20, 21, 22 and 23, the outer mold 2 is taken as an example here, the inner mold 30 has a similar structure, and a plurality of connecting holes 10 are formed in the connecting section 9, and when two outer mold 2 are attached together, the connecting holes 10 in the connecting section 9 are aligned exactly, and of course, the number of the connecting pieces 11 in the same pair of connecting sections 9 can be set as required, and generally three connecting pieces can be set at the uppermost end, the middle end and the lowermost end. The connecting piece 11 firstly comprises a pin shaft 12, the pin shaft 12 penetrates into the connecting holes 10 of the two connecting sections 9, a vertical anti-falling pin piece 13 penetrates through the pin shaft 12, the anti-falling pin piece 13 is wide at the upper part and narrow at the lower part, one side edge of the anti-falling pin piece 13 is attached to one side face of the connecting section 9, a connecting piece 14 perpendicular to the pin shaft 12 is fixed on the pin shaft 12, the connecting piece 14 is located on the other side face opposite to the anti-falling pin piece 13, and the connecting piece 14 is attached to the other side face of the connecting section 9, so that the pin shaft 12 cannot fall out from the connecting holes 10 under the action of the anti-falling pin piece 13 and the connecting piece 14, and when a worker knocks down the anti-falling pin piece 13, the pin shaft 12 is firmer. The connecting piece 14 is also fixedly provided with a limiting piece 15, the horizontal height of the limiting piece 15 is lower than that of the pin shaft 12, the limiting piece 15 is attached to the outer walls of the two connecting sections 9, namely, the distance from the pin shaft 12 to the limiting piece 15 is equal to the distance from the connecting hole 10 to the outer wall of the connecting section 9, through the structure, the whole pin shaft 12 and the connecting piece 14 cannot move left and right, cannot rotate in a vertical plane, and the stability of the connecting piece is ensured. The connecting piece 11 with the structure is simple in structure and convenient and quick to assemble and disassemble.

The connecting piece 11 not only plays a role in assembling the outer mold module 2 and the inner mold module 30, but also plays a role in supporting the back edge mechanism 7, as described above, the back edge mechanism 7 is a mechanism of hooping the outer mold 1 and the inner mold 3, the function is to hold the outer mold 1 from the outside or support the inner mold 3 from the inside, the overall shape of the back edge mechanism 7 is ring-shaped, in order to avoid the back edge mechanism 7 from sliding down due to self gravity, the embodiment supports the back edge mechanism 7 by using the connecting piece 14, and of course, the number of the back edge mechanisms 7 can comprise up and down multiple layers, which is selected according to specific practical situations. The components of the back edge mechanism 7 are shown in fig. 24 and 25, and are respectively back edge plates 31 with two different structures, the whole annular back edge mechanism 7 is formed by sequentially connecting a plurality of arc-shaped back edge plates 31 end to end, wherein the back edge plates 31 shown in fig. 24 are of a single-layer structure, the back edge plates 31 shown in fig. 25 are of a double-layer structure, the strength is higher, and the number and central angles of the back edge plates 31 can be selected according to requirements.

As shown in fig. 23, the back edge plate 31 just falls on the connecting piece 14, and as the back edge plate 31 has weight, the back edge plate will apply downward force to the connecting piece 14, so that the limit piece 15 is more attached to the outer wall of the connecting section 9, and the whole structure of the outer mold 1 and the inner mold 3 will be firmer. In order to avoid the back edge plate 31 from separating from the connecting sheet 14, in this embodiment, a fastening pin sheet 16 penetrating from top to bottom is further arranged on the connecting sheet 14, the fastening pin sheet 16 has a structure similar to that of the anti-drop pin sheet 13, and is also in a shape with a wide upper part and a narrow lower part, one side edge of the fastening pin sheet 16 is attached to the outer wall of the back edge plate 31, a worker only needs to strike the fastening pin sheet 16 downwards, so that the back edge plate 31 is clamped more firmly, and when the back edge plate needs to be detached, only needs to strike the anti-drop pin sheet 13 or the fastening pin sheet 16 from bottom to top.

When the outer mold 1 is disassembled, the base 5 is fixed, and the outer mold receiving tray 51 and the outer bottom plate 23 drive the whole outer mold 1 to be split into two parts, so that the mold is disassembled. Of course, as shown in fig. 10, after the assembly is completed, the outer mold 1, the inner mold 3 and the base 5 need to be in sealing contact, so as to enclose a closed concrete pouring area 4, and leakage is avoided when concrete is poured.
