Description

Technical Field

[0001] This utility model relates to the field of fire protection facility installation technology, and in particular to an auxiliary device for fire sprinkler pipe installation. Background Technology

[0002] A fire sprinkler pipe installation auxiliary device is a professional tool used in building fire protection engineering to facilitate the installation of fire sprinkler pipes. It typically consists of a support structure, positioning components, an adjustment mechanism, and fixing clamps. Its function is to precisely determine the installation position and angle of the sprinkler pipe through the positioning components, achieve installation requirements at different heights and in different spaces through the adjustment mechanism, and secure the sprinkler pipe with the fixing clamps to prevent displacement or shaking during installation. This effectively improves the installation efficiency and accuracy of fire sprinkler pipes, ensures installation quality, reduces worker labor intensity and safety risks, and ensures the safe, efficient, and high-quality completion of the fire sprinkler system installation.

[0003] When using the fire sprinkler pipe installation auxiliary device, it is fixed to the ground or wall by a bottom sturdy bracket or suction cup to form a support base; the lifting and adjusting mechanism drives the sprinkler pipe to the target position, the rotating mechanism realizes the horizontal or vertical adjustment, and the clamping component fixes the sprinkler pipe by mechanical clamping or magnetic adsorption to ensure the stability of the pipeline during the installation process, and finally realizes the rapid and accurate installation of the sprinkler pipe.

[0004] However, some existing fire sprinkler pipe installation auxiliary devices suffer from inconvenience in installation and assembly. The connection methods between the components are complex and cumbersome, requiring numerous specialized tools and involving many steps, consuming significant time and effort from construction personnel. During assembly, poor fit and inaccurate positioning between components often result in incomplete connections due to interface size errors, or even forced connections leading to insufficient overall structural stability. Furthermore, some auxiliary devices employ an integrated design to achieve specific functions, resulting in bulky devices that are difficult to install quickly and flexibly in narrow or complex construction sites. This severely impacts the overall progress and efficiency of fire sprinkler pipe installation, while also increasing construction costs and safety hazards. Therefore, this paper proposes a fire sprinkler pipe installation auxiliary device to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an auxiliary device for fire sprinkler pipe installation, which aims to improve the problem of inconvenient installation and splicing of existing fire sprinkler pipe installation auxiliary devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary device for installing fire sprinkler pipes, comprising an angle steel base, a steel pipe I fixedly connected to the top of the angle steel base, a steel pipe II fixedly connected to the inner wall of the steel pipe I, multiple nuts fixedly connected to the front exterior of the steel pipe I, screws threadedly connected to the interior of the multiple nuts, control panels fixedly connected to the front of the multiple screws, a retraction column fixedly connected to the rear bottom of the steel pipe II, a spring sleeved on the exterior of the retraction column, a steel ball fixedly connected to the rear side of the retraction column, a cross steel frame fixedly connected to the top of the steel pipe II, an arc-shaped steel fork fixedly connected to the top of the cross steel frame, and a clamping assembly for auxiliary fixing fixedly connected to the interior of the top of the steel pipe II.

[0007] As a further description of the above technical solution: the clamping assembly includes a fixed column, the fixed column is externally fixedly connected to the inner wall of the top end of the steel pipe II, two guide columns are fixedly connected to the top end of the fixed column, push rods are slidably connected to the inner walls of the two guide columns, two telescopic columns I are fixedly connected to the top ends of the two push rods, a rotating shaft I is rotatably connected to the top ends of the multiple telescopic columns I, a connecting plate is rotatably connected to the outside of the multiple rotating shafts I, and a rotating shaft II is fixedly connected to the bottom end of the multiple connecting plates on opposite sides.

[0008] As a further description of the above technical solution: the bottom ends of the plurality of rotating shafts are respectively rotatably connected to telescopic columns, and the top ends of the two guide columns are respectively fixedly connected to fixed discs.

[0009] As a further description of the above technical solution: the bottom ends of the two push rods are respectively fixedly connected to control bars, and the bottom ends of the multiple telescopic columns are respectively fixedly connected to the top ends of the two fixed plates.

[0010] As a further description of the above technical solution: anti-slip pads are fixedly connected to the top of the plurality of connecting plates respectively, and the outer surfaces of the plurality of connecting plates are slidably connected to the inner walls of the two guide posts.

[0011] As a further description of the above technical solution: multiple limiting slots are provided on the rear inner wall of the steel pipe, and the steel ball is externally fixedly connected to the rear inner wall of the steel pipe.

[0012] As a further description of the above technical solution: the front side of the spring is fixedly connected to the rear bottom end of the second steel pipe, and the rear side of the spring is fixedly connected to the front exterior of the steel ball.

[0013] As a further description of the above technical solution: the rear side of the plurality of screws is fixedly connected to the front side of the second steel pipe, and the external threads of the plurality of screws are connected to the front side inner wall of the first steel pipe.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, rotating the control disc drives the screw to rotate inside the nut, causing the second steel pipe to move inside the first steel pipe, adjusting the height of the device. The steel ball cooperates with the limiting slot to achieve positioning and fixation after height adjustment. The spring pushes the steel ball into the limiting slot to ensure positioning stability. The cross steel frame and the arc-shaped steel fork are fixed at the top of the second steel pipe and move with the change of the height of the second steel pipe, thereby realizing convenient assembly of the device. The screw adjustment, steel ball limiting and spring positioning achieve flexible adjustment of height and angle, improving installation adaptability and stability.

[0016] 2. In this utility model, pressing down the control bar drives the push rod to slide downwards within the guide column, causing the first telescopic column to shorten. The shortening of the first telescopic column causes the connecting plate to rotate around it via the first rotating shaft, causing the connecting plate to move inwards. The swinging of the connecting plate causes the second telescopic column to retract via the second rotating shaft, further closing the distance between the multiple connecting plates. As the control bar continues to press down, the multiple connecting plates with anti-slip pads gradually clamp the pipe. The fixed plate provides a support point for the second telescopic column, ensuring the stability of the second telescopic column during its retraction process. This achieves a stable clamping of the pipe, increases friction, and prevents the installation operation from being affected by the slippage between the pipe and the device during pipe installation, effectively ensuring the safety and accuracy of the installation process.

[0023] 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.

[0024] Reference Figures 1 to 3 This utility model provides an embodiment of a fire sprinkler pipe installation auxiliary device, including an angle steel base 1. The angle steel base 1, through its own weight and structural characteristics, firmly adheres to the ground, reducing the risk of displacement during use. A steel pipe 2 is fixedly connected to the top of the angle steel base 1. This fixed connection forms the vertical frame of the device, providing an installation carrier for subsequent components such as the steel pipe 3, thus creating an orderly structural system and enhancing the overall strength and stability of the device.

[0025] Steel pipe 2 is fixedly connected to the inner wall of steel pipe 2. This nested structure design provides flexibility in height adjustment, meeting diverse installation height requirements on construction sites, improving the versatility and applicability of the device, and reducing installation inconvenience caused by height limitations. Multiple nuts 5 are fixedly connected to the front exterior of steel pipe 2. The function of nuts 5 is to provide a foundation for the threaded connection of screw rod 4. Through cooperation with screw rod 4, precise control of the position of steel pipe 2 3 is achieved. Screw rod 4 is threadedly connected to the interior of each of the multiple nuts 5. When the operator rotates screw rod 4, due to the transmission principle of the thread, screw rod 4 will move axially within the nut 5, thereby driving the connected steel pipe 2 3 to be fixed within steel pipe 2. Control discs 6 are fixedly connected to the front of each of the multiple screw rods 4. Control discs 6 increase the contact area between the operator and the screw rod 4, allowing the operator to rotate the screw rod 4 more easily and effortlessly.

[0026] A retractable column 7 is fixedly connected to the bottom rear side of steel pipe 2. When steel pipe 2 moves inside steel pipe 2, the retractable column 7 can extend and retract accordingly, providing support and connection for steel ball 9. A spring 8 is sleeved on the outside of the retractable column 7, and a steel ball 9 is fixedly connected to the rear side of the retractable column 7. When steel pipe 2 is adjusted, the spring 8 will generate corresponding elastic force according to the position change of steel pipe 2, pushing the retractable column 7 and steel ball 9 to move towards the limiting groove on the inner wall of steel pipe 2, ensuring that steel ball 9 can accurately enter the limiting groove and lock the position of steel pipe 2.

[0027] A cross-shaped steel frame 10 is fixedly connected to the top of steel pipe 2 (3). The cross-shaped steel frame 10 is fixed to the top of steel pipe 2 (3) by welding or bolting. Its cross-shaped structure design has good mechanical properties, which can evenly distribute the load from the upper arc-shaped steel fork 11 and the fire sprinkler pipe. The arc-shaped steel fork 11 is fixedly connected to the top of the cross-shaped steel frame 10. The arc-shaped design of the arc-shaped steel fork 11 is adapted to the circular cross-section of the fire sprinkler pipe, allowing it to fit tightly against the surface of the sprinkler pipe, increasing the contact area and thus providing better support and clamping effect. A clamping assembly for auxiliary fixing is fixedly connected inside the top of steel pipe 2 (3).

[0028] Reference Figures 2 to 4 The clamping assembly includes a fixed post 12, which is externally fixedly connected to the inner wall of the top end of the steel pipe 3, serving as the basic fixing component of the entire clamping assembly and providing installation support points for subsequent components. Its vertical and stable installation method ensures that when subjected to external forces from the clamping operation, the load can be evenly transferred to the steel pipe 3, maintaining the structural stability of the clamping assembly and the entire device. Two guide posts 16 are fixedly connected to the outer top end of the fixed post 12. The guide structure provides precise path guidance for the sliding of the push rod 13, restricting the push rod 13 to move only in a specific direction and preventing it from deviating or wobbling during movement.

[0029] Push rods 13 are slidably connected to the inner walls of the two guide posts 16. When the operator applies external force to push the push rods 13, the push rods 13 can slide smoothly up and down within the guide posts 16. Two telescopic posts 14 are fixedly connected to the tops of the two push rods 13. When the push rods 13 slide up and down within the guide posts 16, they drive the telescopic posts 14 to move synchronously. The telescopic posts 14 can extend or shorten according to the moving distance of the push rods 13, thereby changing their own length and providing power and displacement for the rotation of the connecting plate 19. Rotating shafts 15 are rotatably connected to the tops of the multiple telescopic posts 14. When the telescopic posts 14 extend or shorten, a torque is applied through the rotating shafts 15, causing the connecting plate 19 to rotate around the rotating shafts 15, thereby changing the angle and position of the connecting plate 19.

[0030] Multiple rotating shafts 15 are rotatably connected to connecting plates 19. When the telescopic column 14 moves, the connecting plates 19 rotate around the rotating shafts 15, moving towards or away from the fire sprinkler pipe. Simultaneously, the rotation of the connecting plates 19 is constrained and coordinated by the rotating shaft 18 and the telescopic column 17, ensuring stable rotation and meeting clamping requirements. Rotating shafts 18 are fixedly connected to the bottom ends of the multiple connecting plates 19 on opposite sides. When the connecting plates 19 rotate, they drive the telescopic column 17 via the rotating shafts 18. The rotating shafts 18 also provide constraint and support for the rotation of the connecting plates 19, ensuring stability and accuracy during rotation, allowing them to move along the expected trajectory.

[0031] Reference Figures 1 to 3 Multiple rotating shafts 18 are rotatably connected to telescopic columns 17 at their bottom ends. When the connecting plate 19 rotates under the drive of the telescopic column 14, it pulls or pushes the telescopic column 17 to extend or retract via the rotating shafts 18. Fixed plates 21 are fixedly connected to the top ends of the two guide columns 16. The fixed plates 21 serve as the lower fixed base for the telescopic column 17. During the extension and retraction of the telescopic column 17, they bear the tension or pressure from the telescopic column 17 and evenly transmit these forces to the guide columns 16 and the fixed columns 12, ultimately distributing them onto the steel pipe 3.

[0032] Control bars 22 are fixedly connected to the bottom ends of the two push rods 13. Operators can slide the push rods 13 within the guide column 16 by pressing down or pulling up the control bars 22. As a key component for human-machine interaction, the control bars 22 concentrate the operator's force to the push rods 13, enabling direct control of the clamping component's movement. Their operation is simple and intuitive, reducing the difficulty of operation for construction personnel. The bottom ends of multiple telescopic columns 17 are fixedly connected to the tops of two fixed plates 21. When the connecting plate 19 rotates, causing the telescopic columns 17 to extend or retract, the fixed plates 21, as fixed ends, effectively constrain the direction of movement of the telescopic columns 17, ensuring they extend or retract along a predetermined trajectory, thus making the rotation of the connecting plate 19 more stable and precise.

[0033] Multiple connecting plates 19 are fixedly connected to their top ends with anti-slip pads 20. When the connecting plates 19 approach and clamp the fire sprinkler pipe, the anti-slip pads 20 are in close contact with the pipe surface. Utilizing their high friction and unique surface structure, they increase the friction between the anti-slip pads and the pipe, preventing the pipe from sliding during clamping. The external parts of the multiple connecting plates 19 are slidably connected to the inner walls of two guide posts 16. This slidable connection with the guide posts 16 enhances the stability and accuracy of the movement of the connecting plates 19, allowing the clamping assembly to maintain a good structural shape during operation. This effectively improves the clamping accuracy and reliability of the clamping assembly for the fire sprinkler pipe, ensuring smooth installation. Multiple limiting slots are provided on the rear inner wall of steel pipe 2, and the external parts of the steel balls 9 are fixedly connected to the rear inner wall of steel pipe 2. The steel balls 9 are connected to steel pipe 3 via the contraction post 7 and spring 8. Under the elastic force of the spring 8, the steel balls 9 always maintain a tendency to move towards the limiting slots on the rear inner wall of steel pipe 2.

[0034] When steel pipe 23 is adjusted to the appropriate height, steel ball 9, pushed by spring 8, engages in the corresponding limiting slot, forming a mechanical locking structure to prevent steel pipe 23 from moving freely within steel pipe 12, ensuring the high stability of the device during use. The front side of spring 8 is fixedly connected to the rear bottom end of steel pipe 23. When steel pipe 23 moves within steel pipe 12, spring 8 will undergo compression or stretching deformation along with the movement of steel pipe 23, generating corresponding elastic force.

[0035] This elastic force pushes the steel ball 9 towards the limiting groove on the inner rear wall of the steel pipe 2, allowing the steel ball 9 to automatically engage with the limiting groove when the steel pipe 3 is adjusted to the appropriate position, thus automatically locking the device height. The rear side of the spring 8 is fixedly connected to the outer front side of the steel ball 9. The rear sides of multiple screws 4 are fixedly connected to the outer front side of the steel pipe 3, and the external threads of the multiple screws 4 are connected to the inner front wall of the steel pipe 2. When the operator rotates the control panel 6, the screws 4 will rotate within the nut 5 and generate axial movement. Since the screws 4 are fixedly connected to the steel pipe 3, the movement of the screws 4 will cause the steel pipe 3 to move up and down or be fixed within the steel pipe 2.

[0036] Working principle: When this fire sprinkler pipe installation auxiliary device is working, rotating the control disc 6 drives the screw 4 to rotate within the nut 5. The screw 4 drives the steel pipe 2 3 to move up and down within the steel pipe 1 2, achieving height adjustment. The spring 8 pushes the steel ball 9 into the limiting groove on the inner wall of the steel pipe 1 2, positioning the adjusted steel pipe 2 3. Continuing to rotate the control disc 6 changes the extension length and direction of the screw 4, which can finely adjust the tilt angle of the steel pipe 2 3 relative to the steel pipe 1 2. The angle steel base 1 is fixedly connected to the steel pipe 1 2 to form a stable support. The cross steel frame 10 and the arc-shaped steel fork 11 are fixed to the top of the steel pipe 2 3, and their positions are adjusted according to the height and angle of the steel pipe 2 3, thereby realizing convenient adjustment of the device's height and angle, meeting the needs of different installation scenarios, while ensuring the stability after adjustment, and improving installation efficiency and accuracy.

[0037] When installing the pipeline, the push rod 13 is driven to slide downward within the guide column 16 by the downward control bar 22. The push rod 13 drives the telescopic column 14 to move downward. The telescopic column 14 causes the connecting plate 19 to rotate inward through the rotating shaft 15. When the connecting plate 19 rotates, it pulls the telescopic column 17 to retract through the rotating shaft 28. The bottom end of the telescopic column 17 is fixed to the fixing plate 21, which further promotes the connecting plate 19 to move closer to the pipeline. Finally, multiple connecting plates 19 with anti-slip pads 20 tightly clamp the pipeline, thereby achieving strong fixation of the pipeline. The anti-slip pads 20 increase the contact friction and effectively prevent the pipeline from slipping during installation, ensuring the stability and safety of the fire sprinkler pipe installation.

[0038] Finally, it should be noted that the above description is only 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, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
