Description

Technical Field

[0001] This utility model relates to the field of pipelines in water supply and drainage engineering, specifically a pipeline fixing support for water supply and drainage engineering. Background Technology

[0002] In the construction and operation and maintenance of water supply and drainage projects, pipe fixing supports are the core auxiliary components that ensure the stable operation of the pipeline system. Their main function is to position and fix the water supply and drainage pipelines, limit the excessive displacement of the pipelines caused by medium flow, temperature changes or external loads, and prevent the pipe joints from loosening, the pipes from deforming or even breaking, thereby ensuring the sealing and flow of the water supply and drainage system.

[0003] Existing pipe fixing supports are mostly one-piece rigid structures with a fixed height during the manufacturing stage. This makes them unable to flexibly adapt to the actual needs of the on-site construction environment. As a result, they cannot meet the usage requirements when there are differences in ground flatness, different laying height requirements, or when fine-tuning settlement is required during operation and maintenance. Construction personnel often adjust them using temporary means such as shims and cutting, which is cumbersome, inefficient, and may weaken the stability of the supports. This can lead to safety hazards such as uneven pipe stress, joint leakage, and support deformation. In addition, the clamping size of traditional supports is fixed and can only be adapted to a single pipe diameter. Different sizes of supports need to be purchased for different specifications, increasing inventory and procurement cycle. Moreover, they are difficult to reuse when the pipeline is changed or upgraded, resulting in material waste, increased costs, and project delays. To address these issues, we propose a new type of pipe fixing support for water supply and drainage engineering. Utility Model Content

[0040] Structural Description:

[0041] Base plate 1: It is flat in shape and is fixedly connected to the mounting surface (ground, wall, etc.) to provide a stable support foundation for the entire bracket, while bearing the weight of the square sleeve 2 and all the structures above it;

[0042] Square sleeve 2: It is a square tube with open ends, which provides a closed installation space for the height adjustment structure to avoid the exposure of the adjustment components. At the same time, it serves as a guide carrier for the telescopic tube 15 and limits the radial displacement of the telescopic tube 15.

[0043] Protective tube 3: It is a square tube that fits the square sleeve 2. It is sleeved on the outside of the square sleeve 2, covering the open end of the square sleeve 2 and the second slot 21, preventing dust and water vapor from entering the height adjustment structure and protecting the sliding fit between the second slot 21 and the support rod 14.

[0044] Support plate 4: It is flat in shape and connects telescopic tube 15 and adjustment box 5. It transmits the supporting force of telescopic tube 15 to adjustment box 5, and provides a fixed end for protective tube 3 to ensure that protective tube 3 rises and falls synchronously with telescopic tube 15.

[0045] Adjustment box 5: It is a box-shaped structure with a top slot 18, which provides a closed installation space for the size adjustment structure, restricts the displacement of the adjustment components, and provides a sliding guide for the limit rod 6 through the top slot 18;

[0046] Limiting rod 6: It is rod-shaped and connects the slider 19 with the clamping structure. It transmits the sliding power of the slider 19, and at the same time, it passes through the strip hole 18 to restrict the slider 19 from rotating with the double screw 17. It can also fix the corrugated plate 8 and drive it to deform.

[0047] Arc plate 7: The shape is an arc plate with the concave side facing the pipe. It fits against the outer wall of the pipe, reduces the gap between the pipe and the clamping components, avoids local stress concentration on the pipe, and works with locking bolt 10 to achieve stable clamping of the pipe.

[0048] Corrugated plate 8: It is a retractable corrugated flexible plate that is snapped into the slot 18, covering the opening of the slot 18. It deforms synchronously with the sliding of the limit rod 6 to prevent impurities from entering the adjustment box 5 and to protect the threaded pair of the size adjustment structure.

[0049] Fixed plate 9: It is a flat plate with an open waist-shaped hole 20. It connects the arc plate 7 and the locking bolt 10. The waist-shaped hole 20 provides height adjustment space for the locking bolt 10, which can be adapted to pipes of different diameters. It can be used with the locking bolt 10 to fasten the arc plate 7.

[0050] Locking bolt 10: It is shaped like a bolt assembly and is inserted into the oblong hole 20. When tightened, it secures the two fixing plates 9 and drives the arc plate 7 to clamp the pipe, thereby increasing the clamping force and preventing the pipe from loosening.

[0051] Motor 11: The main body of the motor is square with an output shaft. It serves as the power source for the height adjustment structure. The output shaft drives the lead screw 12 to rotate, providing power for the lifting and lowering of the telescopic tube 15, thereby realizing the height adjustment of the bracket.

[0052] Lead screw 12: A cylindrical threaded rod with a single-direction thread, which mates with the threaded hole of telescopic tube 15 to convert the rotational power of motor 11 into the linear lifting motion of telescopic tube 15, while using the self-locking property of the thread to achieve height positioning.

[0053] Bearing housing 13: It is fixed to the support rod 14 by the outer ring and connected to the lead screw 12 by the inner ring, which restricts the radial displacement of the lead screw 12, ensures that the lead screw 12 rotates stably along the axis, and reduces rotational deviation;

[0054] Support rod 14: It is two symmetrically arranged rods, fixed to the inner wall of the square sleeve 2, connecting and supporting the bearing seat 13, providing a stable installation base for the bearing seat 13, and simultaneously slidingly engaging with the strip hole 21 to restrict the rotation of the telescopic tube 15.

[0055] Telescopic tube 15: It is a square tube with open ends and threaded holes and strip holes 21. It is inserted into the square sleeve 2 and threaded to the screw 12 to realize lifting and lowering, adjust the height of the bracket, and support the support plate 4 and the structure above it, and transmit the height adjustment power.

[0056] Motor 2 16: The main body of the motor is square with an output shaft. It serves as the power source for the size adjustment structure. The output shaft drives the double screw 17 to rotate, providing power for the sliding of the slider 19 and realizing the adjustment of the clamping distance.

[0057] Double-rotor screw 17: A cylindrical screw rod with two reverse threads, left and right, which cooperates with the threaded holes of two sliders 19 to convert the rotational power of motor 16 into the reverse linear sliding of slider 19, thereby expanding or reducing the spacing of the clamping structure.

[0058] Strip-shaped hole 18: The shape is a long strip-shaped through hole on the top of the adjustment box 5, which provides sliding guidance for the limit rod 6, restricts the slider 19 from rotating with the double screw 17, and provides installation space for the corrugated plate 8 to ensure stable size adjustment;

[0059] Slider 19: It is a block-shaped part with a threaded hole. It is engaged with the reverse thread of the double-screw screw 17. It slides linearly under the constraint of the limit rod 6 and the strip hole 18, which drives the limit rod 6 and the clamping structure to adjust the spacing and transmit the size adjustment power.

[0060] Waist-shaped hole 20: The shape is a long waist-shaped through hole on the fixed plate 9 along the vertical direction of the long axis, which allows the locking bolt 10 to adjust the height within a certain range. It can adapt to pipes with slight diameter differences without secondary adjustment of the size structure, thus improving clamping compatibility.

[0061] Strip-shaped hole 21: It is a long strip-shaped through hole on both sides of the telescopic tube 15, which slides and engages with the support rod 14, restricting the telescopic tube 15 from rotating with the lead screw 12, ensuring that the telescopic tube 15 rises and falls linearly, and at the same time providing sliding space for the support rod 14 without affecting the lifting stroke.

[0062] Working principle: First, the bracket is fixed to the mounting surface via the base plate 1. The square sleeve 2 provides a closed installation space for the height adjustment structure. In the initial state, the telescopic tube 15 is inserted into the square sleeve 2, and the protective tube 3 is sleeved on the outside of the square sleeve 2 to protect the strip hole 21. When the pipe laying height needs to be adjusted, the motor 11 is started. Its output shaft drives the lead screw 12 to rotate stably in the bearing seat 13 through the coupling. Because the telescopic tube 15 is connected to the lead screw 12 through the threaded hole and is slidably engaged with the support rod 14 through the strip hole 21, the rotational motion of the lead screw 12 is converted into the linear lifting and lowering of the telescopic tube 15, which synchronously drives the support plate 4, the adjustment box 5, and the subsequent structures to lift and lower. The protective tube 3 moves synchronously with the support plate 4 to provide continuous protection. After the height is reached, the motor is turned off. Machine 11 utilizes the self-locking property of the thread to achieve height positioning. Then, motor 2 16 is started, which drives the double-rotor screw 17 to rotate. Because the slider 19 is slidably engaged with the strip hole 18 via the limit rod 6, the left and right threads of the double-rotor screw 17 cause the two sliders 19 to slide in opposite directions, synchronously driving the clamping structure to adjust the spacing. The corrugated plate 8 slides and deforms with the limit rod 6 to close the strip hole 18. After the spacing is adapted to the pipe diameter, motor 2 16 is turned off. Then, the pipe is placed between the two arc plates 7, and the height of the locking bolt 10 is adjusted through the waist-shaped hole 20. The nut is tightened to secure the fixing plate 9, driving the arc plate 7 to clamp the pipe. In later operation and maintenance, the motor can be repeatedly started to adjust the height or clamping spacing without disassembling the bracket. The protective structure ensures the long-term stable operation of the adjustment components.

[0063] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
