Description

Technical Field

[0001] This utility model relates to the field of fixing devices, and in particular to a steel pipe fixing device that is easy to install. Background Technology

[0002] Steel pipe is a hollow, long, strip-shaped tubular material made from steel through specific processes. Its core characteristics lie in its hollow internal structure and cylindrical outer wall, giving it high strength, pressure resistance, corrosion resistance, and machinability. Steel pipe is frequently used in industrial applications. As a hollow tubular material, it combines the high strength of steel with a lightweight design, enabling it to withstand high pressure, high temperature, and corrosive media under complex working conditions while reducing transportation and installation costs. Its hollow structure not only allows for efficient fluid or gas transmission but also allows for modular design to meet the complex layout requirements of industrial equipment piping systems. Furthermore, the low cost and large-scale production capacity of welded steel pipe make it an economical alternative to solid steel in applications such as construction scaffolding and machinery frames. Its comprehensive performance and cost-effectiveness make it an irreplaceable basic material in the industrial sector.

[0003] In existing technologies, steel pipes, as key components for conveying media, structural support, or mechanical transmission in industrial settings, must rely on fixing devices to ensure safety and functionality. This is because steel pipes in industrial environments must withstand various external forces such as gravity, vibration, and wind; failure to fix them may lead to safety hazards such as pipe deformation, joint leaks, or even collapse.

[0004] Currently, common steel pipe fixing devices on the market mainly include welded supports, bolt-fastened clamps, and clamp-type fasteners. While welded supports are stable, the welding process requires professional operators using welding machines and other equipment, which is not only cumbersome but also poses safety hazards such as fire and burns due to high-temperature operations. Furthermore, post-weld adjustments or disassembly are difficult, significantly limiting installation efficiency and ease of maintenance. Bolted clamps, although reusable, require tightening multiple bolts individually during installation, especially in high-altitude or confined spaces, making tightening extremely inconvenient and time-consuming. Bolts are also prone to loosening due to vibration, requiring regular inspection and reinforcement. Clamp-type fasteners rely on the tightness of the clamp, making them susceptible to slippage and displacement when dealing with heavy steel pipes or high-vibration environments. The adjustment process for clamps is also slow, failing to meet the needs of rapid fixing in emergency installations or large-scale construction projects. Therefore, these fixing methods introduce numerous inconveniences and reduce installation efficiency when installing and fixing steel pipes. Therefore, this utility model proposes a steel pipe fixing device that is easy to install. Utility Model Content

[0005] The main objective of this invention is to provide a steel pipe fixing device that is easy to install, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A steel pipe fixing device that is easy to install includes a steel pipe body. A fixing mechanism is provided on the outside of the steel pipe body. The fixing mechanism includes a support platform, a support base, an arc plate, a screw, a connecting shaft, a worm gear, and worm wheels. The support base is fixedly connected to the top surface of the support platform. The worm gear is fixedly connected to both ends of the connecting shaft and is movably connected to the support platform through a second rotating rod on the outer end. The two worm wheels are movably connected to the support platform and mesh with the worm gear through first rotating rods on the top and bottom surfaces, respectively. The screw is fixedly connected to the bottom surface of the side blocks on both sides of the arc plate and is movably connected to a nut fixedly connected inside the first rotating rod.

[0008] Preferably, a set of symmetrical L-shaped mounting seats are fixedly installed on the bottom surface of the support platform, and the vertical side wall of the L-shaped mounting seats is provided with a sliding opening.

[0009] Preferably, the support platform has an internal cavity, and the top and bottom surfaces of the support platform each have a set of symmetrical and through first rotating holes. The left and right side walls of the support platform each have through second rotating holes. The top surface of the support platform is fixedly installed with a support seat having an inwardly concave arc-shaped opening, and the support seat has a first rubber pad fixedly installed inside.

[0010] Preferably, worm gears are fixedly installed at both ends of the connecting shaft, and a second rotating rod is fixedly installed at the outer end of the worm gear. The second rotating rod is movably installed in the second rotating hole, and a handwheel is also fixedly installed on the outer end of one end of the second rotating rod.

[0011] Preferably, the worm gear is provided with a symmetrical set, and a first rotating rod is fixedly installed on the top and bottom surfaces of the worm gear. The first rotating rod is movably installed in the first rotating hole, and a through hole is opened on the top surface of the first rotating rod. A nut is fixedly installed inside the through hole.

[0012] Preferably, a second rubber pad is fixedly installed on the inner wall of the arc-shaped plate, and side blocks are fixedly installed on the left and right sides of the arc-shaped plate respectively. A screw is fixedly installed on the bottom surface of the side block, and the screw is threadedly connected to the nut. A connecting plate is fixedly installed on the bottom ends of the symmetrical screws, and sliders are fixedly installed on the two side walls of the connecting plate respectively. The sliders are movably installed in the sliding opening.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, by laying the fixing mechanism along the installation path of the steel pipe body, the steel pipe body is placed on the support base. Rotating the handwheel drives the worm gear to rotate, which in turn meshes with the worm wheel, causing it to rotate. The worm wheel drives the nut inside the first rotating rod to rotate, and the screw moves downwards under the action of the nut, causing the arc-shaped plate to press against the steel pipe body. Simultaneously, the slider on the connecting plate moves within the sliding opening to maintain stability. Combined with the first and second rubber pads for buffering and shock absorption, this eliminates the need for complex welding and multiple bolt tightening operations, simplifying the installation process, reducing operational difficulty, and allowing ordinary personnel to quickly complete the installation. The stable transmission structure and clamping method provide stronger fixing force compared to traditional fixing components, preventing the steel pipe body from shifting under complex external forces. Later, the mechanism can be easily disassembled and adjusted by rotating the handwheel in the opposite direction, making maintenance convenient. This achieves rapid and stable installation and convenient maintenance of the steel pipe body, effectively improving installation efficiency and extending the service life of the steel pipe body.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1 - Figure 4As shown, an easy-to-install steel pipe fixing device includes a steel pipe body 1. A fixing mechanism 2 is provided on the outside of the steel pipe body 1. The fixing mechanism 2 includes a support platform 3, a support base 9, an arc plate 11, a screw 14, a connecting shaft 17, a worm 18, and worm wheels 21. The support base 9 is fixedly connected to the top surface of the support platform 3. The worm 18 is fixedly connected to both ends of the connecting shaft 17. The worm 18 is movably connected to the support platform 3 through a second rotating rod 19 on its outer end. Two worm wheels 21 are movably connected to the support platform 3 through first rotating rods 22 on the top and bottom surfaces, respectively, and mesh with the worm 18. The screw 14 is fixedly connected to the bottom surface of the side blocks 13 on both sides of the arc plate 11. The screw 14 is movably connected to a nut 24 fixedly connected inside the first rotating rod 22.

[0022] like Figure 3 As shown, a set of symmetrical L-shaped mounting seats 4 are fixedly installed on the bottom surface of the support platform 3, and a sliding opening 8 is provided on the vertical side wall of the L-shaped mounting seat 4. The L-shaped mounting seat 4 on the bottom surface of the support platform 3 provides the installation base for the entire fixing mechanism 2. It can be fixed on the installation plane by bolts and other connecting parts. The sliding opening 8 in the vertical part is used to cooperate with the sliders 16 on both sides of the connecting plate 15 to realize the guiding sliding operation.

[0023] like Figure 3 As shown, the support platform 3 has an inner cavity 5 inside, which provides installation space for transmission components such as worm gear 18 and worm wheel 21. The top and bottom surfaces of the support platform 3 are respectively provided with a set of symmetrical and through first rotating holes 6. The first rotating holes 6 on the top and bottom surfaces are used to install the first rotating rod 22 of the worm wheel 21, ensuring that the worm wheel 21 can rotate freely. The left and right side walls of the support platform 3 are also respectively provided with through second rotating holes 7. The second rotating holes 7 on the left and right side walls are used to install the second rotating rod 19 of the worm gear 18, so that the worm gear 18 can rotate flexibly in them. The top surface of the support platform 3 is fixedly installed with a support seat 9 with a concave arc-shaped opening. The support seat 9 is fixedly installed with a first rubber pad 10 inside. The concave arc-shaped opening of the support seat 9 on the top surface fits the arc-shaped contour of the steel pipe. The first rubber pad 10 inside increases the friction with the surface of the steel pipe and also plays a role in buffering and shock absorption.

[0024] like Figure 4As shown, worm gears 18 are fixedly installed at both ends of the connecting shaft 17, and a second rotating rod 19 is fixedly installed at the outer end of the worm gear 18. The second rotating rod 19 is movably installed in the second rotating hole 7, and a handwheel 20 is also fixedly installed on the outer end of one end of the second rotating rod 19. When the operator rotates the handwheel 20, it drives the second rotating rod 19 and the connecting shaft 17 to rotate, thereby causing the worm gear 18 to rotate. By utilizing the meshing transmission principle of the worm gear 18 and the worm wheel 21, the rotational motion of the handwheel 20 is transmitted to the worm wheel 21. The handwheel 20 provides a convenient operating method, and the operator can easily apply force to rotate it. Through the transmission of the worm gear 18 and the worm wheel 21, the small operating force can be amplified to achieve a smooth and powerful drive of the arc plate 11. The clamping and fixing of the steel pipe body 1 can be completed with a small operating force, reducing the difficulty of operation and improving the installation efficiency.

[0025] like Figure 4 As shown, the worm gear 21 is provided with a symmetrical set on the left and right, and the top and bottom surfaces of the worm gear 21 are respectively fixedly installed with the first rotating rod 22. The first rotating rod 22 is movably installed in the first rotating hole 6, and the top surface of the first rotating rod 22 has a through hole 23. The nut 24 is fixedly installed inside the through hole 23. When the worm 18 rotates, the worm gear 21 rotates accordingly under the meshing action. The first rotating rod 22 on the top and bottom surfaces of the worm gear 21 rotates in the first rotating hole 6, driving the nut 24 in the through hole 23 on the top surface of the first rotating rod 22 to rotate. The nut 24 is threadedly connected to the screw 14. The rotation of the nut 24 causes the screw 14 to move up and down along the axial direction. The meshing transmission of the worm gear 21 and the worm 18 realizes the transmission and conversion of force and motion, converting the rotational motion of the worm 18 into the linear motion of the screw 14. By utilizing the characteristics of the threaded transmission, the moving distance of the screw 14 is precisely controlled, thereby accurately adjusting the position of the arc plate 11, realizing stable clamping of steel pipes of different diameters, and ensuring the fixing effect.

[0026] like Figure 4As shown, a second rubber pad 12 is fixedly installed on the inner wall of the arc-shaped plate 11, and side blocks 13 are fixedly installed on the left and right sides of the arc-shaped plate 11 respectively. A screw 14 is fixedly installed on the bottom surface of the side block 13, and the screw 14 is threadedly connected to the nut 24. A connecting plate 15 is fixedly installed on the bottom end of the symmetrical screw 14, and a slider 16 is fixedly installed on the two side walls of the connecting plate 15 respectively. The slider 16 is movably installed in the sliding opening 8. When the nut 24 rotates, the screw 14 moves up and down under the action of the thread, driving the arc-shaped plate 11 to move synchronously. The connecting plate 15 is fixedly installed on the bottom end of the symmetrical screw 14. The connecting plate 15 connects the two screws 14 into a whole. The sliders 16 on both sides of the connecting plate 15 slide in the sliding mouth 8 of the L-shaped mounting base 4 to ensure that the arc plate 11 rises and falls smoothly. The second rubber pad 12 further enhances the fixing effect on the steel pipe and protects the surface of the steel pipe body 1. The transmission method of the screw 14 and nut 24 enables the arc plate 11 to accurately press the steel pipe body 1. The cooperation between the connecting plate 15 and the slider 16 ensures that the arc plate 11 does not tilt or shift during the movement, and achieves uniform clamping of the steel pipe body 1, which effectively improves the applicability and fixing effect of the fixing device.

[0027] The specific fixing principle of the fixing mechanism 2 for the steel pipe body 1 is as follows:

[0028] When it is necessary to fix the steel pipe body 1, the entire fixing mechanism 2 is first installed through a set of symmetrical L-shaped mounting seats 4 on the bottom surface of the support platform 3, and then installed on the laying path of the steel pipe body 1. The horizontal part of the L-shaped mounting seat 4 is in contact with the installation plane, and it is firmly fixed to the installation plane by bolts and other connecting parts, providing a stable support foundation for the entire device.

[0029] Next, the steel pipe body 1 is placed on the top surface of the support base 9. The first rubber pad 10 fixedly installed inside the support base 9 has a certain elasticity and friction. Its shape matches the arc contour of the steel pipe body 1. In this way, when the steel pipe body 1 is placed, the first rubber pad 10 can closely fit the surface of the steel pipe body 1, which not only increases the friction between the steel pipe body 1 and the steel pipe body 1 and prevents the steel pipe body 1 from sliding during the fixing process, but also plays a role in buffering and shock absorption, reducing the impact of external vibration on the steel pipe body 1 and protecting the steel pipe body 1 from damage.

[0030] Then, the operator begins the fixing operation. The operator rotates handwheel 20, which is fixedly installed on the outer end of the second rotating rod 19. When handwheel 20 rotates, it drives the connected second rotating rod 19 to rotate together. The second rotating rod 19 is movably installed in the second rotating holes 7 opened on the left and right side walls of the support platform 3, ensuring its flexible rotation. The rotation of the second rotating rod 19 also drives the rotation of the connecting shaft 17. Worms 18 are fixedly installed at both ends of the connecting shaft 17, so the worms 18 also rotate. The worms 18 and worm wheels 21 mesh with each other, forming an important transmission mechanism. When the worms 18 rotate, due to the special tooth structure of the worms and worm wheels, the worm wheel 21 will rotate in the inner cavity 5 opened in the support platform 3 under the meshing action. The first rotating rods 22 installed on the top and bottom surfaces of the worm wheel 21 will rotate in the first rotating holes opened in the support platform 3. The first rotating rod 22 rotates internally. During this rotation, the screws 14 mounted on the bottom surfaces of the side blocks 13 on both sides of the arc plate 11 pass through the through holes 23 on the top surface of the first rotating rod 22 and are threadedly connected to the nuts 24 installed in the through holes 23. Due to the rotation of the nuts 24, the screws 14 begin to move axially downward under the action of the threads, and the screws 14 will push the connecting plate 15 downward. When the connecting plate 15 moves, the sliders 16 on both sides will slide within the sliding openings 8 on the side walls of the L-shaped mounting base 4. The screw 14 acts as a limit and guide for movement, ensuring stability and preventing tilting or deviation, thus achieving uniform clamping of the steel pipe body 1. Simultaneously, the screw 14 drives the arc plate 11 downward through the side block 13, continuously rotating the handwheel 20 until the arc plate 11 presses against the surface of the steel pipe body 1 after downward movement. The second rubber pad 12 further enhances the fixing effect of the steel pipe body 1, while protecting the surface of the steel pipe body 1 from scratches and preventing the handwheel 20 from rotating further. Thus, the steel pipe body 1 can be quickly installed and fixed. The stable transmission structure and clamping method provide stronger fixing force compared to traditional fasteners, preventing the steel pipe body 1 from shifting under complex external forces. It eliminates the need for complex welding and multiple bolt tightening operations, simplifying the installation process and reducing operational difficulty. Ordinary personnel can quickly complete the installation. Later, it can be easily disassembled and adjusted by rotating the handwheel 20 in the opposite direction, making maintenance convenient. This achieves rapid and stable installation and convenient maintenance of the steel pipe body 1, effectively improving installation efficiency and extending the service life of the steel pipe body 1.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, various improvements can be made to it without departing from the scope of the present utility model, and components can be replaced with equivalents or some technical features can be replaced with equivalents. All such improvements within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
