Description

Technical Field

[0001] The invention mainly relates to the technical field of water conservancy pipeline engineering elements, and in particular to an adjustable supporting structure for water conservancy pipeline installation. Background Art

[0002] The development of many places is constrained by water. In an era when the freshwater crisis is becoming increasingly obvious, surface water resources should be fully utilized. Therefore, it is necessary to artificially transport water resources for reasonable distribution. Due to the advantages of reducing evaporation, facilitating pressure maintenance and pressurization, and high efficiency, the use of pipelines to transport water resources has become the first choice for water transportation.

[0003] After the existing water conservancy pipelines are laid, they are under great pressure and suspended in the air. Therefore, it is necessary to apply support force to the pipelines to prevent them from deformation. The existing pipeline support structures all use arc plates to contact the pipelines. The arc design of the arc plates can better contact the pipelines and provide good support effects. However, the curvature of pipelines with different radii is different, so the arc plates can only be produced in a targeted manner. Once faced with a new pipeline, it needs to be redesigned and produced, which has great limitations. Summary of the invention

[0006] Preferably, the three positioning rods are all telescopic rods.

[0007] Preferably, a fixing frame is connected between one of the positioning rods and the fixed support rod, a rotating disk is arranged inside the fixing frame, and the rotating disk is connected to a threaded rod inside the fixed support rod.

[0008] Preferably, adjusting parts are respectively connected between the other two positioning rods and the corresponding movable support rods, and the adjusting parts include a screw sleeve, and the outer side of the screw sleeve is rotatably connected to a limiting sleeve installed on the positioning rod, a limiting telescopic rod is connected between the limiting sleeve and the movable support rod, and the inner part of the screw sleeve is threadedly connected to a screw rod, and the screw rod is connected to the threaded rod inside the movable support rod.

[0009] Preferably, adjusting gears are installed on both sides of the upper end of the lifting plate through brackets, each of the adjusting gears is meshed with a fixed rack, and the fixed rack is installed on the inner side wall of the fixed support rod or the movable support rod, and the axis of each adjusting gear is connected to a rotating wheel, and the two rotating wheels and the fixed bars on both sides of the lower end of the arc-shaped steel plate are connected by reinforcing ropes, respectively, the axis of the threaded rod is connected to an extension rod, and a bevel gear ring is provided on the extension rod.

[0010] Preferably, each of the adjustment slide grooves is connected to a receiving groove on one side, a driving gear is rotatably installed inside the receiving groove, the driving gear is meshed with an arc-shaped rack sliding inside the receiving groove, one end of the arc-shaped rack is connected to a sliding ring through an extension rod, and in the fixed support rod, the bevel gear ring is meshed with two front and rear fixed bevel gears, and the front and rear two fixed bevel gears are respectively connected to the driving gear axles inside the two receiving grooves.

[0011] Preferably, each of the adjustment slots is also connected to an expansion slot, an arc-shaped positioning rack is installed inside the expansion slot, a follower gear is meshed on the positioning rack, and in the movable support rod, the bevel gear ring is meshed with a single movable bevel gear, and the movable bevel gear and the follower gear are axially connected.

[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) Initially, the curvature of the arc-shaped steel plate is the smallest, and the support mechanism is in a state that can adapt to the minimum radius of the water conservancy pipeline. If the curvature of the arc-shaped steel plate and the water conservancy pipeline are inconsistent at this time, the threaded rod needs to be rotated to move the lifting plate, driving the adjustment gear to move. Since the adjustment gear is meshed with the fixed rack and the position of the fixed rack is fixed, the adjustment gear rotates with the movement of the lifting plate, thereby winding the reinforcing rope, and the reinforcing rope pulls the fixed strips on both sides of the lower end of the arc-shaped steel plate. Since the position of the fixed strip at the center of the lower end of the arc-shaped steel plate remains unchanged, the curvature of the arc-shaped steel plate gradually increases until it can fit the water conservancy pipeline. This allows the support mechanism to be applicable to water conservancy pipelines of different sizes while ensuring the support effect, thereby increasing practicality; (2) When the threaded rod inside the fixed support rod rotates, it will also drive the driving gear to rotate. Since the position of the driving gear is fixed, the arc-shaped rack will move and push the sliding ring to slide inside the adjusting groove, changing the position of the mobile support rod. When facing a small pipe, the two mobile support rods support both sides of the lower end of the small pipe to ensure the supporting effect. As the pipe continues to grow larger, although the angle between the mobile support rod and the fixed support rod also increases, the vertical distance between the mobile support rod and the outermost side of the pipe also increases, resulting in a decrease in the supporting effect. In this structure, the positions of the two mobile support rods change as the pipe grows larger. Therefore, the two mobile support rods can always provide the best supporting effect for the pipe. (3) When the movable support rod moves, because the movable bevel gear and the positioning rack are meshed and the positioning rack is fixed, the movable bevel gear will drive the bevel gear ring to rotate, so that the threaded rod inside the movable support rod rotates, and the arc of the arc steel plate on the movable support rod changes to adapt to pipes of different sizes. Only by operating the fixed support rod, the two movable support rods can be changed at the same time, which reduces the operation steps and further improves the practicality; (4) When the threaded rod inside the mobile support rod rotates, the screw rod will rotate accordingly, so that the limiting sleeve moves to the side away from the mobile support rod, so that the lower ends of the three positioning rods are on the same horizontal plane, avoiding the need for additional steps to adjust the length of the mobile support rod due to the rotation and movement of the two mobile support rods during actual installation; and because the three positioning rods are all telescopic rods, when facing an uneven ground, only the length of the positioning rod needs to be adjusted, avoiding the need for adjustment of the entire device, thereby ensuring practicality. The present invention will be explained in detail in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Embodiment 1: Please refer to the attached Figure 1 and Figure 4-Figure 6 As shown, an adjustable support structure for installing a water conservancy pipeline includes an arc-shaped support frame 1 and three positioning rods 5. The support frame 1 is provided with two front and rear adjustment slots 101, a fixed support rod 2 is provided between the front and rear adjustment slots 101, and the fixed support rod 2 is installed in the center of the support frame 1 in a through-type manner, and movable support rods 3 are respectively provided inside the two adjustment slots 101, and each movable support rod 3 is sleeved with a sliding ring 102, and the sliding ring 102 slides inside the adjusting slot 101, and support mechanisms 4 are respectively provided between the water conservancy pipeline and the fixed support rod 2 and the two movable support rods 3, and the three positioning rods 5 are respectively arranged at one end of the fixed support rod 2 and the two movable support rods 3 away from the water conservancy pipeline.

[0019] Please refer to the attached Figure 1 and Figure 2 As shown, the support mechanism 4 includes an arc-shaped steel plate 401 and a threaded rod 402, the threaded rod 402 is rotatably arranged inside the fixed support rod 2 or the movable support rod 3, and a lifting plate 403 is threadedly connected to the threaded rod 402, and fixing strips 408 are respectively installed on both sides and the center of the lower end surface of the arc-shaped steel plate 401, and a connecting frame 404 is connected between the upper center of the lifting plate 403 and the fixing strip 408 at the lower center of the arc-shaped steel plate 401, and a reinforcing bar 408 is provided between the fixing strips 408 on both sides of the upper end of the lifting plate 403 and the lower end of the arc-shaped steel plate 401. Rope 409; adjusting gears 405 are installed on both sides of the upper end of the lifting plate 403 through brackets, each adjusting gear 405 is meshed with a fixed rack 406, and the fixed rack 406 is installed on the inner side wall of the fixed support rod 2 or the movable support rod 3, and each adjusting gear 405 is connected to a rotating wheel 407 on the axis, and the two rotating wheels 407 and the fixed bars 408 on both sides of the lower end of the arc-shaped steel plate 401 are connected by reinforcing ropes 409 respectively, and an extension rod is connected to the axis of the threaded rod 402, and a bevel gear ring 410 is provided on the extension rod.

[0020] Initially, the curvature of the arc-shaped steel plate 401 is the smallest, and the support mechanism 4 is in a state that can adapt to the minimum radius of the water conservancy pipeline. If the curvature of the arc-shaped steel plate 401 and the water conservancy pipeline are inconsistent at this time, the threaded rod 402 needs to be rotated to move the lifting plate 403, thereby driving the adjusting gear 405 to move. Since the adjusting gear 405 is meshed with the fixed rack 406, and the position of the fixed rack 406 is fixed, the adjusting gear 405 rotates with the movement of the lifting plate 403, thereby winding up the reinforcing rope 409, and the reinforcing rope 409 pulls the fixed strips 408 on both sides of the lower end of the arc-shaped steel plate 401. Since the position of the fixed strip 408 at the center of the lower end of the arc-shaped steel plate 401 remains unchanged, the curvature of the arc-shaped steel plate 401 gradually increases until it can fit the water conservancy pipeline, so that the support mechanism 4 can be applied to water conservancy pipelines of different sizes while ensuring the supporting effect, thereby increasing practicality.

[0021] Please refer to the attached Figure 2 and Figure 5-Figure 7 As shown, each adjusting slide groove 101 is connected to a receiving groove 105 on one side, and a driving gear 103 is rotatably installed inside the receiving groove 105. The driving gear 103 is meshed with an arc-shaped rack 104 that slides inside the receiving groove 105. One end of the arc-shaped rack 104 is connected to the sliding ring 102 through an extension rod. In the fixed support rod 2, the bevel gear ring 410 is meshed with two front and rear fixed bevel gears 411, and the front and rear two fixed bevel gears 411 are respectively connected to the axis of the driving gear 103 inside the two receiving grooves 105. When the threaded rod 402 inside the fixed support rod 2 rotates, the driving gear 103 is also driven to rotate. Since the driving gear 103 is fixed in position, the arc-shaped rack 104 will move and push the sliding ring 102 to slide inside the adjusting slide groove 101, thereby changing the position of the movable support rod 3. When facing a small pipe, the two movable support rods 3 support both sides of the lower end of the small pipe to ensure the supporting effect. As the pipe continues to grow larger, although the angle between the movable support rod 3 and the fixed support rod 2 also increases, the vertical distance between the movable support rod 3 and the outermost side of the pipe also increases, resulting in a reduction in the supporting effect. In this structure, the positions of the two movable support rods 3 change as the pipe becomes larger. Therefore, the two movable support rods 3 can always provide the best supporting effect for the pipe.

[0022] Please refer to the attached Figure 2 and Figure 5-Figure 8As shown, each adjustment chute 101 is also connected to an expansion slot 106, and an arc-shaped positioning rack 107 is installed inside the expansion slot 106, and a follower gear 108 is meshed on the positioning rack 107. In the mobile support rod 3, a single mobile bevel gear 412 is meshed with the bevel gear ring 410, and the mobile bevel gear 412 is axially connected to the follower gear 108. When the mobile support rod 3 moves, because the mobile bevel gear 412 is meshed with the positioning rack 107, and the position of the positioning rack 107 is fixed, the mobile bevel gear 412 will drive the bevel gear ring 410 to rotate, so that the threaded rod 402 inside the mobile support rod 3 rotates, and the arc of the arc-shaped steel plate 401 on the mobile support rod 3 changes to adapt to pipes of different sizes. Only by operating the fixed support rod 2, the two mobile support rods 3 can be changed at the same time, which reduces the operation steps and further improves the practicality.

[0023] Embodiment 2: Based on Example 1, please refer to the attached Figure 1-Figure 3 As shown, the lower ends of the three positioning rods 5 are on the same horizontal plane. A fixing frame is connected between one of the positioning rods 5 and the fixed support rod 2, a rotating disk 501 is arranged inside the fixing frame, and the rotating disk 501 is connected to the threaded rod 402 inside the fixed support rod 2, and adjusting members are respectively connected between the remaining two positioning rods 5 and the corresponding movable support rods 3, and the adjusting members include a screw sleeve 502, a limiting sleeve 503 installed on the positioning rod 5 is rotatably connected to the outer side of the screw sleeve 502, a limiting telescopic rod 504 is connected between the limiting sleeve 503 and the movable support rod 3, a screw rod 505 is threadedly connected inside the screw sleeve 502, and the screw rod 505 is connected to the threaded rod 402 inside the movable support rod 3. When the threaded rod 402 inside the movable support rod 3 rotates, the screw rod 505 will rotate accordingly, so that the limiting sleeve 503 moves to the side away from the movable support rod 3, so that the lower ends of the three positioning rods 5 are on the same horizontal plane, avoiding the need for additional steps to adjust the length of the movable support rod 3 due to the rotational movement of the two movable support rods 3 during actual installation.

[0024] The three positioning rods 5 are all telescopic rods. When facing the uneven ground, it is only necessary to adjust the length of the positioning rods 5, avoiding the need for adjustment of the entire device, thereby ensuring practicality.

[0025] The specific operations are as follows: The driving rotating disk 501 rotates, so that the threaded rod 402 inside the fixed support rod 2 rotates accordingly, driving the lifting plate 403 to move, driving the adjusting gear 405 to move, because the adjusting gear 405 is meshed with the fixed rack 406, and the fixed rack 406 is fixed in position, so the adjusting gear 405 rotates with the movement of the lifting plate 403, thereby winding up the reinforcing rope 409, and the reinforcing rope 409 pulls the fixing strips 408 on both sides of the lower end of the arc-shaped steel plate 401. Because the position of the fixing strip 408 at the center of the lower end of the arc-shaped steel plate 401 remains unchanged, the curvature of the arc-shaped steel plate 401 gradually increases until it can fit the water conservancy pipeline; When the threaded rod 402 inside the fixed support rod 2 rotates, the driving gear 103 is also driven to rotate. Since the driving gear 103 is fixed in position, the arc-shaped rack 104 will move and push the sliding ring 102 to slide inside the adjusting slot 101, thereby changing the position of the movable support rod 3; when the movable support rod 3 moves, since the movable bevel gear 412 is meshed with the positioning rack 107 and the positioning rack 107 is fixed in position, the movable bevel gear 412 will drive the bevel gear ring 410 to rotate, thereby rotating the threaded rod 402 inside the movable support rod 3, thereby changing the curvature of the arc-shaped steel plate 401 on the movable support rod 3 to adapt to pipes of different sizes; When the threaded rod 402 inside the movable support rod 3 rotates, the screw rod 505 will rotate accordingly, so that the limiting sleeve 503 moves to the side away from the movable support rod 3, so that the lower ends of the three positioning rods 5 are on the same horizontal plane. If the ground is uneven, you only need to adjust the length of the positioning rod 5.

[0026] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
