Description

Technical Field

[0001] This utility model relates to the field of pipe support technology, and in particular to a drainage pipe installation bracket. Background Technology

[0002] In drainage pipeline installation projects, pipe supports are key components for fixing and supporting pipelines, and their stability directly affects the safe operation of the drainage system. Currently, traditional pipe supports generally have the following problems: most supports only achieve support through simple contact at the bottom, without a dedicated anti-slip structure, or only use a single friction surface design. When the pipeline is subjected to water flow impact, vibration, or temperature changes causing displacement, slippage is likely to occur. Long-term use may lead to loosening of pipe joints, leakage, and even safety hazards. Utility Model Content

[0003] The purpose of this utility model is to solve the problems in the background art by proposing a drainage pipe installation bracket.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a drainage pipe installation bracket, comprising a horizontally arranged base frame, wherein detachably connected columns are symmetrically distributed on both sides of the top of the base frame along its length direction, the top ends of the two columns jointly support a pipe support ring for pipe passage, a threaded push rod is threaded vertically through the ring wall of the pipe support ring, the bottom end of the threaded push rod extends toward the inner side of the pipe support ring and is rotatably connected to a compression pad, and its top end extends toward the outer side of the pipe support ring and is fixedly connected to a handle; a load-bearing column extends vertically upward from the middle of the top of the base frame, and a lifting plate is fixedly connected to the top end of the load-bearing column, the lifting plate forming a support surface for the bottom of the pipe, and the base frame is also provided with a lifting plate assembly for enhancing the anti-slip performance of the pipe, the lifting plate assembly including a support along the support Two rotating shafts are symmetrically arranged along the length of the lifting plate. The two rotating shafts are horizontally inserted through the top two sides of the lifting plate along the width direction. Anti-slip protrusions are provided on their outer surfaces. Both ends of the two rotating shafts extend to the outside of the lifting plate and are fixedly fitted with gears. Positioning grooves are opened on the two side walls of the lifting plate along its height direction. Gears that mesh with the gears are slidably embedded in the positioning grooves. Slide rail grooves are opened on the top two sides of the base frame along its length direction. Nut seats are slidably connected in the slide rail grooves. A threaded adjusting rod is mounted between the two nut seats along the length direction of the base frame. A pulling rod is hinged between the top of the nut seat and the bottom of the gear. The pulling rod drives the gear to rise and fall along the positioning groove as the nut seat slides. In turn, the gear drives the rotating shaft to rotate so that the anti-slip protrusions press against the outer wall of the pipe.

[0005] Furthermore, the bottom of the nut seat is provided with a downward protruding slide block, which slides in contact with the inner wall of the slide rail groove, so that the nut seat can be translated along the length of the slide rail groove.

[0007] Furthermore, the top surface of the lifting plate is provided with a plurality of anti-slip particles, which are located between the two rotating shafts; a through groove is provided on the top of the lifting plate corresponding to the position of the rotating shaft, and the rotating shaft is rotatably connected to the lifting plate through the through groove.

[0008] Furthermore, the two ends of the rotating shaft pass through the corresponding side through slots and extend outwards, so that the gear is located on the outer side wall of the lifting plate.

[0009] Furthermore, the outer surface of the threaded adjusting rod is provided with threaded sections with opposite directions of rotation at both ends, and the two nut seats are respectively threaded onto the two threaded sections, so that when the threaded adjusting rod rotates, the two nut seats move towards or away from each other along the slide rail groove.

[0011] In this invention, the anti-slip particles on the surface of the support plate are in the shape of a truncated cone and are coated with tungsten carbide, which can increase the static friction at the bottom of the pipe. The anti-slip protrusions are in close contact with the outer wall of the pipe to provide lateral friction. Combined with the top pressure of the extrusion pad, a three-dimensional constraint system is formed, which effectively prevents the pipe from sliding when impacted or vibrated by water flow.

Detailed Implementation

[0016] Reference Figure 1-3As shown, this utility model provides a technical solution: a drainage pipe installation bracket, including a horizontally arranged base frame 1. The base frame 1 is made of rectangular steel plate, with fixing holes 17 through-holes at its four corners. During installation, expansion bolts or ground nails can be driven into the ground through the fixing holes 17 to firmly fix the base frame 1 to the installation foundation surface, preventing the bracket from shifting when the pipe is under stress. The surface of the base frame 1 is hot-dip galvanized for use in humid environments; adjustable feet can also be optionally installed at the bottom, and the overall height of the bracket can be adjusted by rotating the anchor bolts to adapt to the flatness of different installation base surfaces.

[0017] The base frame 1 has symmetrically distributed columns on both sides of its top along its length. The columns are detachably connected to the base frame 1 by bolts for easy maintenance and replacement. The tops of the two columns are supported by a flange structure for a pipe support ring 2. The pipe support ring 2 is semi-circular, and its inner diameter matches the outer diameter of the drainage pipe to be installed, allowing the pipe to be placed horizontally. The middle of the ring wall of the pipe support ring 2 has a threaded hole in the vertical direction. When the handle is rotated, the compression pad 4 can be stably raised and lowered. The bottom end of the threaded push rod 3 extends towards the inside of the pipe support ring 2, and the end is rotatably connected to the compression pad 4 through a deep groove ball bearing. The inner ring of the bearing is interference-fitted with the bottom end of the threaded push rod 3, and the outer ring is transition-fitted with the mounting hole of the compression pad 4 to achieve low-friction rotation. The compression pad 4 is made of rubber to avoid hard contact with the outer wall of the pipe. The top of the threaded push rod 3 extends outward toward the outside of the pipe support ring 2 and is welded to a handle. When the handle is turned, the threaded push rod 3 rises and falls vertically, causing the compression pad 4 to press against or detach from the top outer wall of the pipe. Its effective stroke can be adjusted in conjunction with the rotation shaft 8 to adapt to changes in the outer diameter tolerance of the pipe, thereby achieving initial fixation of the pipe.

[0018] A load-bearing column 5 is vertically welded upwards at the top center of the base frame 1. A support plate 6 is horizontally welded to the top of the load-bearing column 5. The support plate 6 is made of steel plate, and its upper surface forms a support surface for the bottom of the pipeline. The welding of the support plate 6 and the load-bearing column 5 is carried out using carbon dioxide gas shielded welding, and the welding is continuous along the perimeter of the bottom surface of the support plate 6. During welding, tooling fixtures are used to ensure the flatness of the upper surface of the support plate 6 and its perpendicularity to the pipeline axis. Under the specified concentrated load, the deflection and safety factor meet the design requirements.

[0019] The top surface of the support plate 6 is integrally formed with several anti-slip particles 7. The anti-slip particles 7 are in the form of a truncated cone structure and are arranged in a matrix along the length of the support plate 6. The surface is coated with a tungsten carbide coating, which meets the hardness standard and enhances the wear resistance, thereby increasing the static friction between the bottom of the pipe and the support plate 6.

[0020] The top two sides of the support plate 6 are symmetrically equipped with rotating shafts 8 along its length. By replacing the rotating shafts 8 with different lengths, pipes of different outer diameters can be adapted. A through groove is provided on the support plate 6 corresponding to the position of the rotating shaft 8. The rotating shaft 8 passes horizontally through the through groove along the width direction of the support plate 6 and is rotatably connected to the inner wall of the through groove via bearings. Anti-slip protrusions 9 are spaced apart on the outer surface of the rotating shaft 8, manufactured by a molding process. The protrusion height is adapted to the anti-slip particles 7. A dovetail groove structure is provided at the bottom of the protrusion, which engages with the dovetail tenon on the surface of the rotating shaft 8 and is fixed with countersunk screws to ensure that it does not fall off during pipe vibration. Both ends of the rotating shaft 8 pass through the corresponding through grooves and extend outward to the outside of the support plate 6, and gears 15 are fixedly fitted on the extended ends.

[0021] Positioning grooves 10 are formed on both sides of the lifting plate 6 along its height direction. The positioning grooves 10 are rectangular grooves, and a toothed rail 11 is slidably embedded in them. One side of the tooth surface of the toothed rail 11 meshes with the gear 15, and the other side slides against the inner wall of the positioning groove 10 to ensure that the toothed rail 11 can be stably raised and lowered in the vertical direction. The gear 15 and the toothed rail 11 have the same module, the tooth surface hardness meets the standard, and the meshing backlash is controlled within a reasonable range. When the toothed rail 11 is raised and lowered, the rotating shaft 8 can rotate accordingly to ensure that the anti-slip protrusion 9 contacts the pipe at a reasonable angle.

[0022] The top two sides of the base frame 1 are provided with dovetail-shaped slide rail grooves 16 along its length, and nut seats 13 are slidably connected in the grooves. The bottom of the nut seat 13 is provided with a dovetail slider that is adapted to the dovetail-shaped slide rail groove. The slider slides in cooperation with the inner wall of the slide rail groove, so that the nut seat 13 can move smoothly along the length of the slide rail groove 16. A threaded adjusting rod 14 is provided between the two nut seats 13 along the length of the base frame 1. The two ends of the outer surface of the threaded adjusting rod 14 are provided with trapezoidal threads with opposite directions of rotation. The two nut seats 13 are respectively threaded onto the two threaded sections. One end of the threaded adjusting rod 14 extends to the outside of the base frame 1 and is fixed with an adjusting handle. A limiting boss is provided on the base frame 1. When the nut seat 13 moves to the limit position, the boss contacts the limiting block of the nut seat 13 to prevent the threaded adjusting rod 14 from rotating excessively.

[0023] A pull rod 12 is hinged between the top of the nut seat 13 and the bottom of the gear rail 11. The two ends of the pull rod 12 are rotatably connected to the nut seat 13 and the gear rail 11 respectively via pins. The pins are made of 45# steel with heat treatment and hard chrome plating. They are clearance-fitted (H8 / f7) with the hinge holes of the nut seat 13 and the gear rail 11 to ensure flexible rotation without obvious movement. Elastic retaining rings are provided at both ends of the pins to prevent axial dislodgement.

[0024] The lifting plate assembly is an anti-slip support system consisting of a rotating shaft 8, anti-slip protrusions 9, gears 15, toothed rails 11, pulling rods 12, nut seats 13, and threaded adjusting rods 14; it is a three-dimensional constraint system that provides bottom friction through anti-slip particles 7, lateral friction through anti-slip protrusions 9, and top pressure through compression pads 4.

[0025] Working principle: When the adjusting handle is turned to rotate the threaded adjusting rod 14 clockwise, the two nut seats 13 move towards each other along the dovetail slide rail groove 16, driving the pulling rod 12 to rotate around the hinge point, and driving the gear rail 11 to rise along the positioning groove 10; when the gear rail 11 rises, it drives the gear 15 to rotate, causing the rotating shaft 8 to rotate synchronously, ultimately realizing that the anti-slip protrusion 9 rotates towards the outer wall of the pipe and presses against it. Experimental data shows that when tested on a standard steel pipe, the coefficient of friction of the anti-slip protrusion 9 after being pressed meets the GB / T3932-2008 standard.

[0026] This utility model achieves the clamping and fixing of the top of the pipe by rotating the threaded top rod 3. At the same time, by adjusting the threaded adjusting rod 14, the anti-slip protrusion 9 is driven to make close contact with the outer wall of the pipe. Combined with the friction of the anti-slip particles 7, the stability of the pipe after installation is significantly improved, and the pipe is prevented from sliding when water flows or vibrates. It is suitable for the installation and fixing of drainage pipes of different diameters, and each component can be disassembled and connected for easy maintenance and replacement.

[0027] The electrical components mentioned above are all readily available on the market, so wiring and wire connections are not discussed in detail as they are not related to innovation. Some electrical components can also be obtained through private customization, so they will not be discussed in detail thereafter.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
