Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a special vertical steel formwork for the construction of concrete cooling towers in thermal power plants. Background Technology

[0002] Cooling towers in thermal power plants are primarily used to cool circulating water, lowering the water temperature through heat exchange between the water and air. The working principle involves spraying hot water onto the packing material, where it convects with the rising cold air, carrying away heat through evaporation and thus achieving cooling. Cooling towers typically consist of a condenser, a circulating water pump house, and the tower itself, ensuring effective dissipation of heat generated during power generation. Water-saving devices are usually incorporated into the design of cooling towers to minimize water loss.

[0003] In the existing technology, during the construction of cooling towers, concrete needs to be poured using formwork. Formwork includes steel formwork and combined wooden formwork. The joints of the formwork need to be rigidly connected with bolts to form a stable formwork support system to resist the lateral pressure generated during concrete pouring. However, during the casting process using templates, the cooling tower requires a stable base during construction. When casting the base, the template needs to be flipped. Since the template is spliced ​​together, it needs to be disassembled before the flipping process. Then, the templates need to be joined together in an up-and-down manner. This process may involve multiple people working together, and this method may require adjustments after the joint. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a special vertical steel formwork for the construction of concrete cooling towers in thermal power plants.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vertical special steel formwork for the construction of concrete tower cylinder of cooling tower in thermal power plant, comprising a formwork 1, a formwork 2 provided at the bottom end of the formwork 1, the bottom end of the formwork 1 being rotatably spliced ​​with the top end of the formwork 2, a fixing plate provided on one side of both the formwork 1 and the formwork 2, the side of the formwork 1 and the formwork 2 being fixedly connected to one side of the fixing plate, a turntable provided inside the fixing plate, the inside of the fixing plate being rotatably connected to one end of the turntable, a connecting frame provided at one end of the turntable, the end of the turntable being fixedly connected to one end of the connecting frame, an L-rod provided on the inner side of the connecting frame, the inner side of the connecting frame being rotatably connected to one end of the L-rod.

[0006] In a preferred embodiment, one end of the L-rod is provided with a rotating shaft, and one end of the L-rod is fixedly connected to one end of the rotating shaft.

[0007] In a preferred embodiment, one end of the rotating shaft is provided with a connecting arm, and one end of the rotating shaft is rotatably connected to one end of the connecting arm.

[0008] In a preferred embodiment, both template one and template two have a groove on one side, and an mating plate is provided on the inner surface of the groove. The inner surface of the groove is slidably connected to one side end of the mating plate.

[0009] In a preferred embodiment, a fastener is provided on the inner wall of the edge of the bonding plate, and the inner wall of the edge of the bonding plate is threadedly connected to the outer side of the fastener.

[0010] In a preferred embodiment, an inner roller is provided on one side of the turntable, and the connecting end of the inner roller is fixedly connected to one side of the turntable.

[0011] In a preferred embodiment, the outer side of the inner roller is in rolling connection with the inner surface of the fixed disc.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. By rotating template 2 180 degrees, after template 2 has completed its first rotation, the two L rods are rotated 180 degrees around the point where they are connected to the connecting arm. The moving template 2 is moved from below template 1 to above template 1. After template 2 moves to above template 1, a rotational driving force is applied to template 2 again, causing it to rotate 180 degrees around its own axis for the second time. Finally, the bottom end of template 2 is precisely aligned with the top end of template 1, thus forming a continuous vertical template flipping. 2. By pushing the mating plates on template one and template two together, the two mating plates are brought into contact. At this time, the two mating plates are fixed with fasteners. This method can achieve a pulling effect, so that after the two templates are joined, the radial expansion trend of the template caused by the lateral pressure of the concrete during subsequent concrete pouring can be effectively counteracted, and misalignment at the joint of template one and template two can be avoided.

[0019] 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 protection scope of the present utility model. Example

[0020] like Figure 1-5 As shown, this utility model provides a technical solution: a vertical special steel formwork for the construction of concrete cooling tower cylinders in thermal power plants, including a formwork 11, a formwork 2 12 at the bottom end of the formwork 11, the bottom end of the formwork 11 and the top end of the formwork 2 12 being rotatably spliced, a fixing plate 13 on one side of both the formwork 11 and the formwork 2 12, and one side of the formwork 11 and the formwork 2 12 being fixedly connected to one side of the fixing plate 13, a turntable 14 inside the fixing plate 13, the interior of the fixing plate 13 being rotatably connected to one end of the turntable 14, and a connecting frame 15 at one end of the turntable 14. One end of the turntable 14 is fixedly connected to one end of the connecting frame 15. An L-rod 16 is provided on the inner side of the connecting frame 15. The inner side of the connecting frame 15 is rotatably connected to one end of the L-rod 16. A rotating shaft 110 is provided on one end of the L-rod 16. One end of the L-rod 16 is fixedly connected to one end of the rotating shaft 110. A connecting arm 17 is provided on one end of the rotating shaft 110. One end of the rotating shaft 110 is rotatably connected to one end of the connecting arm 17. An inner roller 19 is provided on one side of the turntable 14. The connecting end of the inner roller 19 is fixedly connected to one side of the turntable 14. The outer side of the inner roller 19 is rollingly connected to the inner surface of the fixed disk 13.

[0021] In this embodiment, when using the vertical special steel formwork for the construction of the concrete tower of the cooling tower of a thermal power plant, formwork 11 consists of two arc-shaped plates forming a ring, and formwork 2 12 is similar. The two are presented in an up-down manner, with formwork 2 12 located below formwork 11. A fixing plate 13 is installed on one side of both formwork 2 12 and formwork 11. The two fixing plates 13 are located at the waist (middle) of formwork 11 and formwork 2 12, respectively. A turntable 14 is rotatably connected to the center of the fixing plate 13, and one end of each turntable 14 is connected to a connecting... The frame 15 is concave, and two L-shaped rods 16 are connected to its inner side via rotating components. One end of each L-shaped rod 16 is fixed to a rotating shaft 110, which is connected to a connecting arm 17. The middle end of the connecting arm 17 corresponds to the connection point between template 11 and template 2 12. Therefore, during mold flipping, template 2 12 can be rotated 180 degrees by multiple people working together. During the flipping process, the position is adjusted through the rotational engagement of the turntable 14 and the fixed plate 13, and the linkage between the L-shaped rods 16 and the rotating components of the connecting frame 15. The specific flipping trajectory can be found in [reference needed]. Figure 2 As shown, after template 2.12 completes its first flip, according to... Figure 3 The structure shown allows for the movement of the second movable template 12 from below the first template 11 to above it by rotating the two L-bars 16 180 degrees around the point where they connect to the connecting arm 17. Once the second movable template 12 is above the first template 11, according to... Figure 4 As shown in the assembly requirements, a rotational driving force is applied to template 2 12 again, causing it to rotate 180 degrees around its own axis for the second time, so that the bottom end of template 2 12 is precisely connected with the top end of template 1 11, thereby forming a continuous vertical template system, which provides stable forming support for the subsequent layered pouring of cooling tower cylinder concrete. By installing two guide rollers on the turntable 14, the rollers of the guide rollers roll in contact with the inner surface of the fixed disk 13. When the turntable 14 rotates around the center of the fixed disk 13, the rollers roll in a circular motion along the inner surface of the fixed disk 13 as the turntable 14 rotates. By replacing the traditional sliding friction with rolling friction, the resistance of the turntable 14 when rotating is greatly reduced. At the same time, the presence of the guide rollers can help reduce the load pressure on the turntable 14. Example

[0022] like Figure 1-5 As shown, both template 11 and template 2 have a groove 18 on one side. The inner surface of the groove 18 is provided with a mating plate 111. The inner surface of the groove 18 is slidably connected to one side end of the mating plate 111. A fastener 112 is provided on the inner wall of the edge of the mating plate 111. The inner wall of the edge of the mating plate 111 is threadedly connected to the outer side of the fastener 112.

[0023] In this embodiment, grooves 18 are provided on one side of both template 11 and template 2 12. The inner surface of the grooves 18 is slidably connected to the side protrusion of the mating plate 111. After template 11 and template 2 12 are joined, the mating plates 111 on each template are pushed together to make them stick together. At this time, the two mating plates 111 are fixed by the fastener 112. This method can achieve a pulling effect, so that after the two templates are joined, the radial expansion trend of the templates caused by the side pressure of the concrete during subsequent concrete pouring can be effectively offset. This avoids gaps or misalignment at the joint of template 11 and template 2 12, so that the two templates always maintain a tight and stable overall state after joining.

[0024] Working principle: like Figure 1-5 As shown, template 2 12 is rotated 180 degrees by multiple people working together. During the rotation, the position is adjusted by the rotation of turntable 14 and fixed plate 13, and by the linkage of L-rod 16 and rotating component of connecting frame 15. After template 2 12 completes its first rotation, the two L-rods 16 are rotated 180 degrees around the point where they connect to connecting arm 17, moving template 2 12 from below template 1 11 to above it. After template 2 12 moves to above template 1 11, a rotational driving force is applied to template 2 12 again, causing it to rotate 180 degrees around its own axis for a second time. Finally, the bottom end of template 2 12 is precisely aligned with the top end of template 1 11, thus forming a continuous vertical template flipping system. After template 1 11 and template 2 12 are aligned, the mating plates 111 on each template are pushed together to make them stick together. At this time, the fasteners 112 are used to fix the two mating plates 111. This method can achieve a pulling effect, so that after the two templates are aligned, they can effectively counteract the radial expansion trend of the template caused by the lateral pressure of the concrete during subsequent concrete pouring, and avoid gaps or misalignment at the joint between template 1 11 and template 2 12.

However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
