Description

Technical Field

[0001] This utility model relates to the field of grouting mold technology, specifically a grouting device for wind turbine foundation concrete. Background Technology

[0002] The wind turbine foundation uses a concrete structure with an internal anchor bolt assembly. This assembly consists of upper and lower anchor plates and anchor bolts. The exposed threaded rods of the anchor bolts at the top of the upper anchor plate are connected to the wind turbine equipment via high-strength nuts. The anchor bolts are fixed according to the design prestressing tension. The upper anchor plate and the concrete structure are filled with high-strength grout. Special molds are used during grouting to ensure the designed shape. Typically, the high-strength grout is designed to be circular, with a width 80mm wider than the inner and outer edges of the upper anchor plate. Because high-strength grout is a fast-setting material, and this part becomes a permanent structure after solidification, the appearance quality is crucial and directly affects the project acceptance evaluation. Special molds are typically used for high-strength grouting. The specific method involves processing the molds into sections according to the inner and outer perimeters of the designed structure. The processing material is usually thin steel plate, and during installation, bolts or special U-shaped pins and straight pins are used for connection and fixation.

[0003] The existing Chinese patent with publication number CN216920417U discloses a special mold for high-strength grouting of wind turbine anchor bolt foundations. It solves the problems of unevenness at the joints of existing wind turbine anchor bolt grouting molds during installation, damage to the grouting structure caused by the need to use a pry bar to disassemble the inner arc-shaped mold, and inconvenience in installation and disassembly. This utility model includes a base plate, with several coaxially connected outer long templates and one outer short template placed at the upper end of the base plate. Several coaxially detachably connected inner templates are placed at the upper end of the base plate. The inner templates have a trapezoidal cross-section and the diameter of the inner templates is smaller than the diameter of the outer long templates and the outer short templates. The outer long templates and the inner templates are fitted with a gap to form a grouting chamber. Both ends of the outer templates and the inner templates are fixedly connected with connecting ribs. The connecting ribs have connecting holes, and two connecting holes are coaxially threaded with fixing bolts.

[0004] Regarding the above-mentioned and existing related technologies, the inventor believes that the following defects often exist: the device improves the strength of the template by strengthening the ribs, but it increases the volume of the template, making it inconvenient to store and transport, and needs to be improved; therefore, in order to solve the above problems, a wind turbine foundation concrete grouting device is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-5As shown, a wind turbine foundation concrete grouting device includes an annular outer mold and an inner mold. The outer mold and inner mold are each composed of several templates 1. A reinforcing component 2 is installed on the outer side of each template 1. The reinforcing component 2 includes several sliding grooves 21 and a positioning seat 26 located above the sliding grooves 21. The sliding grooves 21 are formed on the surface of the templates 1. A sliding plate 22 is slidably connected to the inner wall of the sliding grooves 21. A rotating plate 23 is rotatably connected to the side wall of the sliding plate 22 via a torsion spring shaft. A reinforcing plate 24 is fixedly connected to the side wall of the rotating plate 23. A reinforcing plate 24 is fixedly connected to the top of the rotating plate 23. There is a positioning post 25 and a positioning seat 26 fixedly installed on the upper side wall of the template 1. The surface of the positioning seat 26 is provided with a positioning hole 27 for the positioning post 25 to be inserted. Only the template 1 structure of the outer mold is shown in the figure. The template 1 structure of the inner mold is the same as that of the outer mold, only the size and curvature are different. The inner side of the template 1 is provided with an arc surface. One end of the template 1 is fixedly provided with a limiting protrusion 5, and the other end of the template 1 is provided with a limiting groove 6. Both the limiting protrusion 5 and the limiting groove 6 are T-shaped. The outer side wall of the template 1 is fixedly connected with a fixing hole seat 7.

[0026] Specifically, the fixing hole seat 7 is used for the anchor rod to pass through and insert into the ground, which has the effect of fixing the template 1. The reinforcing plate 24 is folded into the template 1 by the torsion of the torsion spring shaft, thereby reducing the volume of the template 1 and making it easy to carry and store. In use, by sliding the sliding plate 22 downward and rotating the rotating plate 23, the positioning post 25 is rotated to the position hole 27 directly below. Then, the sliding plate 22 is slid upward, so that the positioning post 25 is inserted into the positioning hole 27, which quickly limits and fixes the reinforcing plate 24, so that the reinforcing plate 24 and the template 1 are perpendicularly distributed. When the two are against the ground, the reinforcing plate 24 provides lateral support for the template 1, disperses the squeezing force of the poured concrete on the template 1, and improves the strength of the template 1. The limiting protrusions 5 and limiting grooves 6 of the template 1 are inserted and matched in sequence, so that the template 1 is assembled to form a ring-shaped grouting mold.

[0027] The bottom wall of the slide 21 is fixedly connected to an elastic element 28, which can be a steel leaf spring, a helical spring, a torsion bar spring, a rubber spring, etc. In this embodiment, a helical spring is used. The top of the elastic element 28 is fixedly connected to the slide plate 22.

[0028] Specifically, the elastic element 28 is used to apply an upward elastic force to the slide plate 22, so that the slide plate 22 is tightly pressed against the positioning seat 26.

[0029] The reinforcing plate 24 is designed to be square or triangular.

[0030] Specifically, in this example, the reinforcing plate 24 is triangular.

[0031] When the reinforcing plate 24 is raised or lowered, the highest height of its bottom end is the same as the bottom height of the template 1.

[0032] Specifically, when the positioning hole 27 and the positioning post 25 are inserted and matched, the bottom end of the reinforcing plate 24 is flush with the bottom end of the template 1, so that the bottom end of the reinforcing plate 24 can abut against the ground to provide support for the template 1.

[0033] The top of the template 1 is equipped with an extension component 3, which includes an extension plate 31 and a slot 33. The bottom end of the extension plate 31 is fixedly connected to a plugging protrusion 32. The slot 33 is opened on the top of the template 1. The plugging protrusion 32 is plugged into the slot 33. One end of the extension plate 31 is fixedly provided with a connecting protrusion, and the other end of the extension plate 31 is fixedly provided with a connecting groove. The connecting protrusion and the connecting groove are T-shaped.

[0034] Specifically, when the mold height is insufficient, by inserting the insertion protrusion 32 into the slot 33, the extension plate 31 can be inserted and matched with the template 1, thereby increasing the grouting height of the mold and improving the flexibility of mold use. Furthermore, by sequentially inserting the connecting protrusions of multiple extension plates 31 into the connecting slots, the connection strength of the extension plates 31 can be improved, and the tightness of the connection between the extension plates 31 can be increased.

[0035] The template 1 is internally fixedly connected with ribs 4, and the side wall of the extension plate 31 is fixedly connected with support inserts 34.

[0036] Specifically, by inserting the support plate 34 above the rib plate 4, lateral support can be provided to the extension plate 31, thereby increasing the strength of the extension plate 31.

[0037] The surface of the support plate 34 is provided with a second groove 35. An L-shaped retaining plate 36 is slidably connected inside the second groove 35. An elastic element 37 is fixedly connected to the side wall of the retaining plate 36. The elastic element 37 can be a steel leaf spring, a coil spring, a torsion bar spring, a rubber spring, etc. In this embodiment, a coil spring is used. The other end of the elastic element 37 is fixedly installed on the inner side wall of the second groove 35. The extension component 3 also includes several L-shaped slots 38, which are opened on the top of the template 1.

[0038] Specifically, the card plate 36 is inserted into the card slot 38 through the elastic element 37, which can lock the template 1 and the extension plate 31 to prevent the extension plate 31 from falling off accidentally. When the extension plate 31 needs to be disassembled, the card plate 36 is pushed to slide, so that the card block and the card slot 38 are misaligned, and the connection can be quickly canceled for easy installation.

[0039] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0040] The parts of the device not covered herein are the same as or can be implemented using existing technologies.

[0041] Working principle: During use, by sliding the sliding plate 22 downward and rotating the rotating plate 23, the positioning post 25 is rotated to the position directly below the positioning hole 27. Then, the sliding plate 22 is slid upward, so that the positioning post 25 is inserted into the positioning hole 27, which quickly limits and fixes the reinforcing plate 24, so that the reinforcing plate 24 and the template 1 are perpendicularly distributed. When the two are against the ground, the reinforcing plate 24 provides lateral support for the template 1, disperses the extrusion pressure on the template 1 applied by the poured concrete, and improves the strength of the template 1. After the reinforcing plate 24 is unfolded, the limiting protrusions 5 and limiting grooves 6 of the template 1 are sequentially inserted and matched, so that the template 1 is assembled to form a ring-shaped grouting mold.

[0042] When the mold height is insufficient, the extension plate 31 can be inserted into the slot 33 by inserting the insertion protrusion 32 into the interior of the slot 33, thereby increasing the grouting height of the mold and improving the flexibility of mold use. Furthermore, by sequentially inserting the connecting protrusions of multiple extension plates 31 into the connecting slots, the connection strength of the extension plates 31 can be improved, and the tightness of the connection between the extension plates 31 can be increased.

[0043] The card plate 36 is inserted into the slot 38 through the elastic element 37, which can lock the template 1 and the extension plate 31 to prevent the extension plate 31 from falling off accidentally. When the extension plate 31 needs to be disassembled, the card plate 36 is pushed to slide so that the card block and the slot 38 are misaligned, and the connection can be quickly canceled for easy installation.
