Description

Technical Field

[0001] This utility model relates to the field of pipe support technology, and in particular to a pipe support with adjustable height and angle. Background Technology

[0002] As energy transmission and water supply pipeline projects expand into areas with complex terrain, the limitations of traditional pipeline supports are becoming increasingly apparent. In these regions, traditional rigid supports cannot effectively cope with varying terrain, requiring frequent adjustments to design and construction methods during installation, consuming significant manpower, resources, and time. Furthermore, once a support malfunctions, repairs are extremely difficult, leading not only to pipeline interruptions but also to severe economic losses. Therefore, developing a new type of pipeline support capable of adapting to complex terrain is of paramount importance.

[0003] A search revealed Chinese Patent Publication No. CN210687268U, which discloses an adjustable pipe support in the field of pipe support technology. The support includes a base, a height adjustment mechanism fixedly connected to the center of the top of the base, telescopic support columns on both sides of the height adjustment mechanism, a lower pipe fixing frame fixed to the top of the height adjustment mechanism, and an upper pipe fixing frame above the lower pipe fixing frame. Mounting ears are provided on both sides of the upper and lower pipe fixing frames, and are locked together by bolts. Roller mounting grooves are formed in the inner cavities of the upper and lower pipe fixing frames, and several rollers are arranged within the inner cavities of the roller mounting grooves. Roller pins are fixed within the inner cavities of the rollers, and are rotatably mounted to the front and rear side walls of the roller mounting grooves via bearings. This invention provides an adjustable pipe support, making the pipe support more flexible and greatly reducing the difficulty of pipe transportation. It also allows for adjustments to the height and angle of the pipe according to different geographical environments and needs. However, this device can only adjust the installation height of the pipe. In complex terrain, when the pipe needs to be turned laterally at a certain distance from the support column, it cannot effectively fix the pipe at different installation points. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pipe support with adjustable height and angle, aiming to improve the problem that the existing technology cannot effectively fix pipes at different installation points.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable height and angle pipe support, comprising a column, a hydraulic rod fixedly connected to the inner wall of the column, a base fixedly connected to the bottom end of the hydraulic rod, threaded rods threadedly connected to the four corners of the top of the base, insertion claws fixedly connected to the bottom of multiple threaded rods, an outer tube of a support arm rotatably connected to the top of the column, an inner tube of a support arm slidably connected to the left side of the inner wall of the outer tube of the support arm, multiple positioning holes opened on the left side of the outer wall of the outer tube of the support arm, multiple insertion holes opened on the left and right sides of the top of the inner tube of the support arm, a positioning pin slidably connected to the inner wall of the positioning hole on the left side, the bottom end of the positioning pin passing through the insertion hole on the left side and threadedly connected to a nut, a pipe clamp fixedly connected to the bottom left side of the inner tube of the support arm, and a balancing mechanism provided on the outer wall of the outer tube of the support arm.

[0006] The above technical solution involves connecting the column to a hydraulic rod, with the bottom of the hydraulic rod fixed to the base. The extension and retraction of the hydraulic rod allows for flexible adjustment of the height between the column and the base, thus adapting to pipes at different installation heights and effectively solving the problem of height differences during actual installation. At the four corners of the base top, threaded rods are connected to insertion claws. Operators can adjust the height of the insertion claws by rotating the threaded rods. This design is designed for uneven installation surfaces, allowing the insertion claws to better grip the ground, enhancing the stability of the entire support and ensuring secure pipe installation. The top of the column features a rotating support arm outer tube, allowing it to change direction to adapt to pipes with different orientations and meet the installation requirements of complex pipe layouts. Inside the support arm outer tube, an inner support arm tube is slidably connected. By inserting a positioning pin into the positioning hole on the support arm outer tube and the insertion hole on the support arm inner tube, and securing it with a nut, the extension length of the support arm inner tube can be precisely adjusted. Furthermore, the distance between the pipe clamp and the column can be adjusted to accommodate pipes with different degrees of curvature, improving the versatility and practicality of the pipe support.

[0007] As a further description of the above technical solution: The balancing mechanism includes a limiting ring, which is fixedly connected to the upper side of the outer wall of the upright. A rotating sleeve is slidably connected to the outer wall of the limiting ring. A fixed sleeve is fixedly connected to the left side of the outer wall of the support arm outer tube. Multiple reinforcing rods are fixedly connected between the fixed sleeve and the rotating sleeve. A counterweight box is fixedly connected to the right side of the outer wall of the support arm outer tube.

[0008] Through the above technical solution: On the left side of the outer wall of the support arm, the fixed sleeve and the rotating sleeve are fixedly connected by multiple reinforcing rods. The reinforcing rods provide support force to the outer wall of the support arm from multiple directions, effectively enhancing the overall structural strength. When the outer wall of the support arm is subjected to external force and tends to tilt, the reinforcing rods and the rotating sleeve work together to provide a reverse force, offsetting part of the external force that causes tilting. At the same time, a counterweight box is set on the right side of the outer wall of the support arm. By increasing the weight on the right side, the counterweight box enables the outer wall of the support arm to achieve left-right balance when under force. Once the left side experiences uneven force due to factors such as the pipeline, the reverse torque generated by the counterweight box can effectively prevent the outer wall of the support arm from tilting excessively, ensuring that the entire pipeline support stably supports the pipeline and improving the stability during pipeline installation and use.

[0009] As a further description of the above technical solution: Multiple anti-slip plates are fixedly connected to the inner wall of the pipe clamp around its perimeter, and the surfaces of the multiple anti-slip plates are all treated with anti-slip coating.

[0010] The above technical solution involves pipe clamps used to fix pipes. Anti-slip pads are installed around the inner wall of the clamps. The surface of the anti-slip pads is treated with anti-slip material to increase surface roughness. When the pipe clamps tighten around the pipe, the anti-slip pads come into contact with the pipe. This rough surface can effectively increase the friction between the pipe clamps and the pipe, making the pipe clamps hold the pipe more securely and preventing the pipe from loosening or slipping during use, thus ensuring the reliability of the pipe installation.

[0011] As a further description of the above technical solution: Limiting strips are fixedly connected to the front and rear sides of the inner wall of the outer tube of the support arm, and limiting grooves are opened on the front and rear sides of the outer wall of the inner tube of the support arm. The two limiting strips are slidably connected to the corresponding limiting grooves.

[0012] Through the above technical solution, the limiting strip is slidably connected to the corresponding limiting groove, which can prevent the inner tube of the support arm from rotating during sliding and ensure the stability of sliding.

[0013] As a further description of the above technical solution: Multiple sleeves are fixedly connected to the bottom of the outer wall of the column, and guide rods are slidably connected to the bottom of the inner wall of each sleeve. The guide rods are fixedly connected to the base.

[0014] The above technical solution involves sleeves around the bottom of the column, which fit onto guide rods fixed to the base, guiding the column's lifting and lowering and ensuring its smooth up-and-down movement.

[0015] As a further description of the above technical solution: Gaskets are provided at the four corners of the top of the base, and multiple threaded rods pass through the corresponding gaskets.

[0016] The above technical solution involves placing gaskets at the four corners of the base top, with the threaded rod passing through the gaskets. This increases the contact area between the threaded rod and the base, dispersing pressure and preventing damage to the base.

[0017] As a further description of the above technical solution: The outer walls of the multiple guide rods are fixedly connected with reinforcing ribs, and the bottom ends of the multiple reinforcing ribs are threadedly connected to the base.

[0018] The above technical solution involves reinforcing ribs on the outer wall of the guide rod, with their bottom ends threaded to the base, which enhances the stability of the guide rod and helps it better assist in related adjustment operations.

[0019] As a further description of the above technical solution: The spacing between the plurality of positioning holes is equal, and the outer wall of the positioning pin is treated with anti-slip treatment.

[0020] The above technical solution utilizes multiple equally spaced positioning holes to ensure uniform stress distribution on the structure. The outer wall of the positioning pins is treated with an anti-slip coating to prevent loosening within the positioning holes and insertion holes, thus securing the inner tube of the support arm.

[0021] This utility model has the following beneficial effects: 1. In this utility model, the height of the column is adjusted by the extension and retraction of the hydraulic rod to adapt to pipes with different installation heights. The threaded rod at the top of the base cooperates with the insertion claw to adjust the insertion depth to adapt to uneven installation surfaces and enhance installation stability. The outer tube of the support arm is rotatably connected to the top of the column, and the inner tube of the support arm slides inside the outer tube of the support arm and is fixed by the positioning pin and nut. This allows for adjustment of the direction of the support arm and the distance between the pipe clamp and the column, adapting to pipes with different directions and degrees of curvature, and effectively improving the situation where the existing technology cannot fix the pipe at different installation points.

[0022] 2. In this utility model, the balancing mechanism is slidably connected to the rotating sleeve through the limiting ring, allowing the rotating sleeve to rotate flexibly and the connection to be stable. The fixed sleeve is connected to the rotating sleeve by the reinforcing rod, which enhances the connection strength and supports the outer tube of the support arm from multiple directions. When the outer tube of the support arm is subjected to external force and is about to tilt, this structure applies a reverse force to offset part of the tilting force. At the same time, the counterweight box is fixed to the right side of the outer tube of the support arm, increasing the weight on the right side. When the force on the left side is uneven, a reverse torque is generated to prevent the outer tube of the support arm from tilting excessively, thereby achieving the function of maintaining the overall stability of the pipe support.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of an adjustable-height and adjustable-angle pipe support, comprising a column 1, which serves as the main vertical support structure for the entire pipe support, providing a foundation for the installation and support of other components. A hydraulic rod 3 is fixedly connected to the inner wall of the column 1, and a base 4 is fixedly connected to the bottom end of the hydraulic rod 3. This fixed connection with the inner wall of the column 1 allows the distance between the column 1 and the base 4 to be adjusted through telescopic movement, thereby achieving adjustment of the overall height of the pipe support. The base 4, through its fixed connection to the bottom end of the hydraulic rod 3, provides stable bottom support for the entire pipe support. The top of the base 4 has four... Each corner is threaded with a threaded rod 5, and the bottom of each threaded rod 5 is fixedly connected to an insertion claw 6. The threaded connection between the threaded rod 5 and the four corners of the top of the base 4 allows the operator to change the extension length of the threaded rod 5 on the base 4 by rotating it, thereby adjusting the height of the insertion claw 6 to adapt to different levels of flatness on the installation surface. The fixed connection between the insertion claw 6 and the bottom of the threaded rod 5 allows the insertion claw 6 to be inserted into the ground or installation surface after the height of the threaded rod 5 is adjusted, increasing the friction and grip between the pipe support and the installation surface, and improving the stability of the entire support under different terrain conditions. The top of the column 1... The outer tube 7 of the support arm is rotatably connected to the column 1, allowing it to rotate horizontally around the top of the column 1. This adjusts the direction of the outer tube 7 to accommodate different pipe installation requirements. An inner tube 8 of the support arm is slidably connected to the left side of the inner wall of the outer tube 7. The inner tube 8 can slide left and right within the outer tube 7, adjusting the distance between the pipe clamp 13 and the column 1 to accommodate pipes with different degrees of curvature or installation positions. Multiple positioning holes 9 are provided on the left side of the outer wall of the outer tube 7 to provide insertion positions for positioning pins 11. Positioning holes 9 are also provided on the top left and right sides of the inner tube 8. There are multiple insertion holes 10, which correspond to the positioning holes 9 on the left side of the outer wall of the support arm outer tube 7, and are used to cooperate with the positioning pins 11. After the positioning pins 11 are inserted into the positioning holes 9, they pass through the insertion holes 10, thereby realizing the positioning and fixing of the inner tube 8 of the support arm. The inner wall of the left positioning hole 9 is slidably connected with the positioning pins 11. The bottom end of the positioning pins 11 passes through the left insertion holes 10 and is threaded with a nut 12. The bottom left side of the inner tube 8 of the support arm is fixedly connected with a pipe clamp 13, which is used to clamp the pipe and fix the pipe on the pipe support to ensure the stability of the pipe during installation and use. The outer wall of the support arm outer tube 7 is provided with a balancing mechanism 2. Specifically, column 1 is connected to hydraulic rod 3, and the bottom end of hydraulic rod 3 is connected to base 4. By extending and retracting hydraulic rod 3, the height between column 1 and base 4 can be adjusted to meet the different installation height requirements of pipelines. The threaded rods 5 at the four corners of the top of base 4 are connected to insertion claws 6. Rotating threaded rods 5 can adjust the height of insertion claws 6 to adapt to uneven installation surfaces and enhance the stability of the support. The top of column 1 is rotatably connected to the outer tube 7 of the support arm, so that it can change direction to adapt to pipelines with different orientations. The inner tube 8 of the support arm is slidably connected inside the outer tube 7. The positioning pin 11 is inserted into the positioning hole 9 of the outer tube 7 and the insertion hole 10 of the inner tube 8, and fixed with nut 12. The extension length of the inner tube 8 of the support arm can be adjusted, thereby adjusting the distance between the pipeline clamp 13 and column 1 to adapt to pipelines with different degrees of curvature.

[0027] Reference Figure 1 , Figure 2 and Figure 5 The balancing mechanism 2 includes a limiting ring 201, which is internally fixedly connected to the upper side of the outer wall of the column 1. As a basic component of the balancing mechanism 2, the limiting ring 201 provides a track for the installation and sliding of the rotating sleeve 202, limiting the range of motion of the rotating sleeve 202. The rotating sleeve 202 is slidably connected to the outer wall of the limiting ring 201. Through this slidable connection, the rotating sleeve 202 can rotate flexibly within a certain range while maintaining a connection with the limiting ring 201, providing a rotatable connection point for subsequent structures. The outer tube 7 of the support arm... A fixed sleeve 203 is fixedly connected to the left side of the wall. Multiple reinforcing rods 204 are fixedly connected between the fixed sleeve 203 and the rotating sleeve 202. The multiple reinforcing rods 204 connect the fixed sleeve 203 and the rotating sleeve 202, providing support force to the outer tube 7 of the support arm from multiple directions. A counterweight box 205 is fixedly connected to the right side of the outer tube 7 of the support arm. By increasing the weight on the right side of the outer tube 7 of the support arm, a reverse torque is generated when the outer tube 7 of the support arm is subjected to uneven force, so as to balance the unbalanced force on the left side of the outer tube 7 of the support arm caused by factors such as pipes. Specifically, the outer wall of the limiting ring 201 is slidably connected to the rotating sleeve 202, which allows the rotating sleeve 202 to rotate flexibly relative to the limiting ring 201 while restricting its radial movement to ensure structural stability. The fixed sleeve 203 on the left side of the outer wall of the support arm outer tube 7 is fixedly connected to the rotating sleeve 202 by multiple reinforcing rods 204. These reinforcing rods 204 provide support force to the support arm outer tube 7 from different directions, enhancing its overall structural strength. When the support arm outer tube 7 is subjected to external force and tends to tilt, the reinforcing rods 204 and the rotating sleeve 202 can provide a counterforce to offset part of the external force that causes tilting. The counterweight box 205 on the right side of the outer wall of the support arm outer tube 7 increases the weight on the right side, so that the support arm outer tube 7 is balanced left and right when subjected to force. Once the left side is subjected to uneven force due to factors such as the pipeline, the counterforce generated by the counterweight box 205 can effectively prevent the support arm outer tube 7 from tilting excessively, ensuring that the entire pipeline support stably supports the pipeline.

[0028] Reference Figure 1 , Figure 2 and Figure 4 Multiple anti-slip plates 14 are fixedly connected to the inner wall of the pipe clamp 13. The surfaces of the multiple anti-slip plates 14 are all treated with anti-slip coating, which can increase the friction between the pipe and the pipe and firmly grip the pipe. Limiting strips 15 are fixedly connected to the front and rear sides of the inner wall of the support arm outer tube 7. Limiting grooves 16 are opened on the front and rear sides of the outer wall of the support arm inner tube 8. The limiting strips 15 and the limiting grooves 16 are slidably connected to prevent the support arm inner tube 8 from rotating when sliding. The two limiting strips 15 are slidably connected to the corresponding limiting grooves 16 respectively. Multiple sleeves 17 are fixedly connected to the bottom of the outer wall of the column 1. Guide rods 18 are slidably connected to the bottom of the inner wall of the multiple sleeves 17. The multiple guide rods 18 are fixedly connected to the base 4. The guide rods 18 and the base 4 are fixed to provide guidance for the lifting and lowering of the column 1 and ensure its smooth up and down movement. Specifically, the anti-slip plates 14 around the inner wall of the pipe clamp 13 are treated with anti-slip material to increase the friction between the clamp and the pipe and firmly hold the pipe. The limiting strip 15) and the corresponding limiting groove 16) are slidably connected to prevent the inner tube 8) of the support arm from rotating during sliding, thus ensuring the stability of the sliding. The sleeves 17 around the bottom of the column 1 are fitted onto the guide rod 18. The guide rod 18 is fixed to the base 4, providing guidance for the lifting and lowering of the column 1 and ensuring its smooth up and down movement.

[0029] Reference Figure 1 , Figure 2 and Figure 3 Each of the four corners at the top of the base 4 is provided with a gasket 19, and multiple threaded rods 5 pass through the corresponding gaskets 19 to increase the contact area between the threaded rods 5 and the base 4 and to distribute the pressure. The outer walls of multiple guide rods 18 are fixedly connected with reinforcing ribs 20, and the bottom ends of multiple reinforcing ribs 20 are threaded to the base 4 to enhance the stability of the guide rods 18 and make them better assist in adjustment. The spacing between multiple positioning holes 9 is equal to ensure that the structure is evenly stressed. The outer wall of the positioning pin 11 is treated with anti-slip material to ensure that the inner tube 8 of the support arm is firmly fixed. Specifically, the gaskets 19 at the four corners of the base 4 are penetrated by the threaded rods 5, which increases the contact area between the threaded rods 5 and the base 4, disperses the pressure, and prevents damage to the base 4. The bottom end of the reinforcing ribs 20 on the outer wall of the guide rod 18 is threaded to the base 4, which enhances the stability of the guide rod 18 and makes it better assist in adjustment. The multiple positioning holes 9 are evenly spaced to ensure uniform force on the structure. The outer wall of the positioning pin 11 is treated with anti-slip treatment to prevent it from loosening in the positioning holes 9 and the insertion holes 10, ensuring that the inner tube 8 of the support arm is firmly fixed.

[0030] Working Principle: During actual pipeline installation, the height between the column 1 and the base 4 is first adjusted using hydraulic rod 3 according to the pipeline's installation height. Hydraulic rod 3 is fixed to the inner wall of column 1 and its bottom end is connected to base 4. By extending and retracting hydraulic rod 3, the height of column 1 can be flexibly changed to adapt to different pipeline installation height requirements. If the installation surface is uneven, the threaded rod 5 connected to the four corners at the top of base 4 can be rotated. Since the bottom of threaded rod 5 is fixed with insertion claws 6, rotating threaded rod 5 will drive the insertion claws 6 to move up and down, adjusting the depth of insertion of insertion claws 6 into the ground or installation surface. The outer tube 7 of the support arm is rotatably connected to the top of column 1, which can surround... The support arm can be rotated around the top of the column 1 to adjust the direction of the outer tube 7 of the support arm, so as to meet the installation requirements of the pipeline in different directions. At the same time, the inner tube 8 of the support arm can slide left and right on the left side of the inner wall of the outer tube 7 of the support arm. Multiple positioning holes 9 are opened on the left side of the outer wall of the outer tube 7 of the support arm, and multiple insertion holes 10 are also opened on the left and right sides of the top of the inner tube 8 of the support arm. By inserting the positioning pin 11 into the left positioning hole 9 and through the left insertion hole 10, and then threading the nut 12 to the bottom of the positioning pin 11, the position of the inner tube 8 of the support arm in the outer tube 7 of the support arm can be fixed. In this way, the distance between the pipe clamp 13 and the column 1 can be adjusted to adapt to the pipeline with different degrees of curvature. Furthermore, the balancing mechanism 2 plays a crucial role in preventing the outer tube 7 of the support arm from tilting. The outer wall of the limiting ring 201 is slidably connected to the rotating sleeve 202, allowing the rotating sleeve 202 to rotate flexibly relative to the limiting ring 201 while maintaining a certain connection stability. The fixed sleeve 203 fixed on the left side of the outer wall of the support arm 7 is fixedly connected to the rotating sleeve 202 by multiple reinforcing rods 204. These reinforcing rods 204 enhance the connection strength between the rotating sleeve 202 and the outer tube 7 of the support arm, and provide support to the outer tube 7 of the support arm from multiple directions. When the outer tube 7 of the support arm is subjected to external force... When there is a tendency to tilt, the structure composed of rotating sleeve 202 and reinforcing rod 204 can exert a reverse force on the outer tube 7 of the support arm through its own mechanical structure, offsetting part of the external force that causes tilting. In addition, the counterweight box 205 fixed on the right side of the outer wall of the outer tube 7 of the support arm increases the weight on the right side, so that the outer tube 7 of the support arm can maintain left and right balance when under force. When the left side is tilted due to uneven force on the pipe and other factors, the weight of the counterweight box 205 will generate a reverse torque, effectively preventing the outer tube (7) of the support arm from tilting excessively and ensuring the overall stability of the pipe support.
