Description

Technical Field

[0001] This utility model belongs to the technical field of dam construction equipment, specifically a template support device suitable for the construction of curved surfaces of dam overflow surfaces. Background Technology

[0002] The spillway is a key hydraulic structure in hydropower projects used to safely discharge excess floodwater and protect the structural safety of the dam. When the reservoir water level exceeds the design flood level, the spillway serves as the main flood discharge channel, safely discharging excess water downstream through overflow holes or gates to prevent the reservoir from overflowing or the dam from collapsing. It is usually located on the top of the dam or on the side of the dam.

[0003] When constructing the curved surface of a dam overflow, it is necessary to first use templates to form the outline of the curved surface before pouring and other operations. In order to ensure the stability of the templates, it is also necessary to use corresponding support devices to support and fix the templates. However, the existing support devices still have shortcomings in actual use. Traditional curved surface template support is complicated, and it is difficult to adjust the support devices after they are connected and fixed to the curved surface templates. The construction efficiency is low, and the accuracy is not easy to guarantee, which can easily have a negative impact on the appearance quality of the overflow surface. Therefore, it is necessary to improve this. Utility Model Content

[0021] 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.

[0022] like Figures 1 to 6As shown, this utility model provides a template support device suitable for the construction of curved surfaces of dam overflow surfaces, including a telescopic rod 1. A fixed shaft 2 is fixedly sleeved at the bottom of the telescopic rod 1. A rotating block 3 is movably sleeved at the middle of the outer surface of the fixed shaft 2. The outer surface of the rotating block 3 is movably sleeved with the inner surface of the bottom end of the telescopic rod 1. A vertical rod 4 is fixedly installed at the middle of the bottom of the outer surface of the rotating block 3. A connecting plate 5 is fixedly installed at the bottom end of the vertical rod 4. A diagonal rod 6 is hinged to the left side of the middle of the rotating block 3. A movable block 7 is hinged to the other end of the diagonal rod 6. The outer surface of the movable block 7 is movably sleeved with the inner surface of the telescopic rod 1. A threaded rod 8 is threadedly sleeved at the top of the middle of the movable block 7. The outer surface of the threaded rod 8 is movably sleeved with the inner surface of the middle end of the telescopic rod 1. A first handle 9 is fixedly sleeved at the top of the outer surface of the threaded rod 8. The outer surface of the first handle 9 is movably sleeved with the inner surface of the telescopic rod 1. Sliding grooves 10 are respectively opened on the inner walls of the left and right sides of the telescopic rod 1. The bottom of the internal part of the 10 is movably fitted with a slider 11, and the outer surface of the slider 11 is fixedly connected to the outer surface of the movable block 7. The bottom of the front and rear ends of the telescopic rod 1 is provided with scales, which can indicate the rotation angle of the vertical rod 4 and the connecting plate 5. When the first handle 9 is turned, the threaded rod 8 will rotate. Since the outer surface of the threaded rod 8 is threadedly fitted to the inner surface of the movable block 7, the movable block 7 will move along the inner surface of the telescopic rod 1 under the action of the threaded rod 8. At the same time, the cooperation between the slide groove 10 and the slider 11 will limit the movement distance of the movable block 7. As the movable block 7 moves, the inclined rod 6 will move along with it, so that the other end of the inclined rod 6 will generate a pulling force on the rotating block 3, pulling the rotating block 3 to rotate the vertical rod 4 and the connecting plate 5 around the fixed shaft 2, thereby realizing the precise adjustment of the angle of the connecting plate 5, so that it can adapt to the overflow surface template with different curvature radii.

[0023] The telescopic rod 1 has a fixed frame 12 movably sleeved on its outer surface, and a top plate 13 is fixedly installed on the top of the fixed frame 12. The fixed frame 12 will provide auxiliary support for the telescopic rod 1, while the top plate 13 will facilitate the construction personnel to connect it with the construction beam by bolts and the round holes at the four corners of the top plate 13, thereby installing and fixing it.

[0024] The fixed frame 12 has a limiting groove 14 on its left inner wall. The top of the limiting groove 14 is movably fitted with a limiting block 15. The right end of the limiting block 15 is fixedly connected to the left end of the telescopic rod 1. The inner surface of the limiting groove 14 and the outer surface of the limiting block 15 are both smooth, which ensures that the limiting block 15 will not get stuck when it moves along the inner surface of the limiting groove 14. At the same time, the cooperation between the limiting groove 14 and the limiting block 15 will restrict the telescopic rod 1 and prevent the telescopic rod 1 from detaching from the fixed frame 12.

[0025] The telescopic rod 1 has a positioning hole 16 in the middle of the right end. The positioning rod 17 located at the bottom of the fixed frame 12 is movably sleeved inside the positioning hole 16. The right end of the positioning rod 17 passes through the telescopic rod 1 and extends to the outside of the telescopic rod 1. The positioning holes 16 are evenly distributed on the right side of the telescopic rod 1. By the mutual engagement of the positioning rod 17 and the positioning holes 16 at different positions, the telescopic rod 1 can be positioned, so that the telescopic rod 1 can be extended and retracted along the inner surface of the fixed frame 12.

[0026] The positioning rod 17 has an outer frame 18 movably sleeved on the right side of its outer surface. The left end of the outer frame 18 is fixedly connected to the right end of the fixed frame 12. A square plate 19 is movably sleeved on the left end of the inner side of the outer frame 18. The left end of the square plate 19 is movably connected to the right end of the fixed frame 12. The inner surface of the square plate 19 is fixedly sleeved on the outer surface of the positioning rod 17. When the positioning rod 17 moves, it will move the square plate 19 along the inner surface of the outer frame 18. Thus, with the cooperation of the outer frame 18 and the square plate 19, the movement of the positioning rod 17 is limited, ensuring the stability of the movement of the positioning rod 17.

[0027] The right end of the square plate 19 is fixedly installed with a spring 20 located outside the positioning rod 17, and the other end of the spring 20 is fixedly connected to the inner wall of the right side of the outer frame 18. When the positioning rod 17 moves along the inner surface of the outer frame 18 with the square plate 19, it will compress the spring 20. Under the restoring action of the spring 20, the square plate 19 will be forced to return to its original position with the positioning rod 17.

[0028] The positioning rod 17 has a round shaft 21 fixedly installed on its right end. The outer surface of the round shaft 21 is movably sleeved with a second handle 22. The left end of the second handle 22 is movably connected to the right end of the outer frame 18. When the second handle 22 is turned, it will rotate around the round shaft 21. Since the length of the second handle 22 is greater than its width, the round shaft 21 will move the positioning rod 17 outward from the outer frame 18 as the second handle 22 rotates.

[0029] Working principle and usage process of this utility model:

[0030] In use, the construction personnel first move the first handle 9 according to the radius of curvature of the overflow surface template, causing the threaded rod 8 to rotate. This causes the movable block 7, which is threaded onto the outer surface of the threaded rod 8, to move along the inner surface of the telescopic rod 1 with one end of the inclined rod 6. This causes the other end of the inclined rod 6 to exert a pulling force on the rotating block 3, pulling the rotating block 3 to rotate the vertical rod 4 and the connecting plate 5 around the fixed shaft 2. Then, the construction personnel read the angle of the vertical rod 4 and the connecting plate 5 through the scale at the bottom of the telescopic rod 1 until the reading matches the radius of curvature of the overflow surface template.

[0031] The construction worker then moves the second handle 22, causing it to rotate around the circular shaft 21. This causes the circular shaft 21, along with the positioning rod 17 and the square plate 19, to move along the inner surface of the outer frame 18 and compress the spring 20. When the second handle 22 rotates 90 degrees, it will be stopped by the restoring action of the spring 20. At this point, the positioning rod 17 will completely separate from the positioning hole 16. The construction worker can then pull the telescopic rod 1, causing it to move along the inner surface of the fixed frame 12 until the connecting plate 5 contacts the overflow surface template. The construction worker can then connect and fix the connecting plate 5 and the overflow surface template with bolts. Finally, the second handle 22 is reset, allowing the positioning rod 17 to be inserted into the corresponding positioning hole 16 under the restoring action of the spring 20.
