Description

Technical Field

[0001] The utility model relates to the field of U-shaped aqueducts, and more specifically to an adjustable U-shaped aqueduct inner mold supporting device. Background Art

[0002] The U-shaped trough is a common farmland water conservancy facility made of concrete or stone. It has a U-shaped structure and can divert, store and drain water. It plays an important role in farmland irrigation and drainage. During the transportation of the U-shaped trough, if you want to prevent the U-shaped trough from being damaged, you need to use a U-shaped trough support device to protect it.

[0003] China Patent Authorization Announcement No.: CN206916703U, provides an inner mold support device for a large reinforced concrete U-shaped aqueduct integral steel mold. This patent ensures the simplicity of the structure of the inner mold support component by setting a U-shaped I-beam arch ring and combining it with a transverse pressure beam. At the same time, it effectively solves the problem of floating, deformation and local bulging of the inner mold during pouring and vibration due to insufficient rigidity of the inner mold.

[0004] In the existing technology, although the interior of the U-shaped groove can be supported, since the angle of the support rod is relatively fixed, when supporting U-shaped grooves of different widths, the support rod with a fixed angle may not touch the inner wall of the U-shaped groove. Therefore, it can only support U-shaped grooves of a single width, which has certain limitations when used. Utility Model Content

[0032] Embodiment 1:

[0033] See also Figure 1-5 A kind of adjustable U-shaped aqueduct inner mold support device comprises a mounting plate 1, the mounting plate 1 is internally rotatably connected with a No. 1 screw rod 11, the outer wall of the No. 1 screw rod 11 is threadedly connected with a moving block 12, the outside of the moving block 12 is fixedly connected with an extrusion block 13, the moving block 12 is slidably connected with the mounting plate 1 inside the mounting plate 1, a base 15 is fixedly connected with the middle part of the bottom surface of the mounting plate 1, a No. 2 screw rod 16 is internally rotatably connected with the base 15, a No. 2 handle 19 is fixedly connected with the top of the No. 2 screw rod 16, the outer wall of the No. 2 screw rod 16 is rotatably connected with a No. 1 handle 14, the No. 1 handle 14 is meshed with the No. 1 screw rod 11 through a bevel gear, the base 15 is internally fixedly connected with a limiting rod 18, the outer wall of the No. 2 screw rod 16 is threadedly connected with a fixing block 17, the fixing block 17 is located inside the base 15, and the fixing block 17 and the limiting rod 18 are slidably connected.

[0034] In this embodiment, when the user rotates the No. 1 handle 14, since the No. 1 handle 14 and the two No. 1 screws 11 are meshed through the bevel gears, the rotation of the No. 1 handle 14 will drive the two No. 1 screws 11 to rotate. After the two No. 1 screws 11 rotate, they will drive the two moving blocks 12 to slide inside the mounting plate 1. When the two moving blocks 12 slide toward the outside of the mounting plate 1, the two extrusion blocks 13 will extrude the inner mold of the U-shaped groove. By adjusting the distance between the two extrusion blocks 13, the purpose of adjusting according to the different widths of the U-shaped groove can be achieved.

[0035] Embodiment 2:

[0036] See also Figure 1-5 The bottom end of the moving block 12 is rotatably connected to the support rod 2, and the bottom end of the moving block 12 is rotatably connected to the connecting plate 21. The side of the connecting plate 21 away from the support rod 2 is fixedly connected to the first extrusion rod 22. The lower end of the connecting plate 21 is rotatably connected to the adjusting plate 23. The upper part of the adjusting plate 23 is rotatably connected to the synchronization rod 25. The side of the synchronization rod 25 away from the adjusting plate 23 is fixedly connected to the second extrusion rod 24. The end of the synchronization rod 25 away from the adjusting plate 23 is rotatably connected to the fixed block 17.

[0037] In this embodiment, when the No. 1 screw rod 11 rotates to drive the moving block 12 to move toward the outside of the mounting plate 1, due to the change in the position of the moving block 12, the support rod 2 will deflect at a certain angle, thereby driving the connecting plate 21 and the No. 1 extrusion rod 22 to move. After the No. 1 extrusion rod 22 touches the inner wall of the U-shaped groove, the No. 1 handle 14 can be stopped from rotating, and the No. 2 handle 19 can be turned at this time. When the user rotates the No. 2 handle 19, the No. 2 screw rod 16 will be driven to rotate, and the No. 2 screw rod 16 will drive the fixed block 17 to move in the vertical direction. When the fixed block 17 moves downward, the synchronization rod 25 will push the adjustment plate 23, causing the adjustment plate 23 to deflect at a certain angle, so that the No. 2 extrusion rod 24 fixedly connected below the adjustment plate 23 completes the extrusion of the inner wall of the U-shaped groove, thereby reinforcing the support of the U-shaped groove.

[0038] The working principle of the utility model is as follows: before use, the user first checks whether the device is damaged. After confirming that the device is not damaged, when the U-shaped groove is about to be transported, the bottom end of the base 15 is fitted with the bottom end of the U-shaped groove, and then the No. 1 handle 14 is turned. When the user turns the No. 1 handle 14, because the No. 1 handle 14 and the two No. 1 screw rods 11 are meshed through the bevel gears, the No. 1 handle 14 will drive the two No. 1 screw rods 11 to rotate when it rotates. When the two No. 1 screw rods 11 rotate, they will drive the two moving blocks 12 to slide inside the mounting plate 1. When the two moving blocks 12 slide toward the outside of the mounting plate 1, the two extrusion blocks 13 will extrude the inner mold of the U-shaped groove. By adjusting the distance between the two extrusion blocks 13, the purpose of adjusting according to the different widths of the U-shaped groove is achieved. When the No. 1 screw rods 11 are rotated, the two moving blocks 12 will slide inside the mounting plate 1. When the two moving blocks 12 slide toward the outside of the mounting plate 1, the two extrusion blocks 13 will extrude the inner mold of the U-shaped groove. By adjusting the distance between the two extrusion blocks 13, the purpose of adjusting according to the different widths of the U-shaped groove is achieved. When the movable block 12 is driven to move toward the outside of the mounting plate 1 by rotation of 11, due to the change in the position of the movable block 12, the support rod 2 will deflect at a certain angle, thereby driving the connecting plate 21 and the No. 1 extrusion rod 22 to move. After the No. 1 extrusion rod 22 touches the inner wall of the U-shaped groove, the No. 1 handle 14 can be stopped from rotating, and the No. 2 handle 19 can be turned at this time. When the user rotates the No. 2 handle 19, the No. 2 screw rod 16 will be driven to rotate, and the No. 2 screw rod 16 will drive the fixed block 17 to move in the vertical direction. When the fixed block 17 moves downward, the synchronization rod 25 will push the adjustment plate 23, causing the adjustment plate 23 to deflect at a certain angle, so that the No. 2 extrusion rod 24 fixedly connected below the adjustment plate 23 completes the extrusion of the inner wall of the U-shaped groove, thereby reinforcing the support of the U-shaped groove.

[0039] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
