Description

Technical Field

[0001] This invention relates to the field of pipeline installation technology in building engineering, and specifically to a concentric device for controlling the installation of pipelines and sleeves. Background Technology

[0002] When laying pipes between floors or between rooms, floor sleeves are usually installed in pre-built walls or floors, and then the pipes are passed through the floor sleeves. Finally, an adhesive material is filled to ensure the integrity and sealing of the floor or room walls. However, the installation specifications for fire protection engineering require that the floor sleeves and pipes be installed concentrically. In actual operation, due to the lack of calibration tools, it is difficult for construction workers to ensure the concentricity of the floor sleeves and pipes. This will directly reduce the construction quality and affect the later fire protection assessment.

[0003] Patent authorization number CN210566721U discloses a concentricity correction device for pipelines. This device corrects the concentricity of the pipeline and the floor sleeve by inserting a correction sleeve between the floor sleeve and the pipeline, allowing the correction guide wheel to contact the circumferential surface of the pipeline and the inner surface of the floor sleeve. However, in practice, the correction sleeve needs to be directly inserted from above into the gap between the floor sleeve and the pipeline. Because the pipeline is initially eccentric, the gap between the floor sleeve and the pipeline is not equidistant, making it difficult to insert the correction sleeve downwards, sometimes even preventing it from being inserted smoothly. The position of the pipeline needs to be adjusted so that the pipeline and the floor sleeve are on the same central axis before the correction sleeve can be inserted smoothly. Therefore, this device can only center the floor sleeve and the pipeline, but cannot directly correct the pipeline's deviation, thus having certain limitations. Therefore, a device for controlling the concentricity of the installed pipeline and the sleeve is needed to improve the installation accuracy and convenience of the pipeline. Summary of the Invention

[0004] To address the aforementioned defects and problems, this invention provides a concentric device for controlling the installation of pipes and sleeves. By setting up a correction mechanism and a fixing mechanism between the fire-fighting pipe and the floor-penetrating sleeve, and by pulling the movable column through the traction component, the pipe is pushed to a position coaxial with the floor-penetrating sleeve through the cooperation of the movable column and the fixed column, thereby realizing the correction of pipe deviation and improving the installation accuracy and convenience of the pipe.

[0005] The solution adopted by this invention to solve its technical problem is: a concentric device for controlling the installation of pipes and sleeves, comprising a ring clamp seat, a correction mechanism, and a tensioning mechanism. The ring clamp seat includes a left and right arc-shaped clamp plate symmetrically arranged on the left and right sides. Connecting rods are symmetrically arranged on the outer walls of the left and right arc-shaped clamp plates. A mounting seat is provided on the side of the ring clamp seat. The left and right arc-shaped clamp plates are hinged to the mounting seat via connecting rods on one side. The correction mechanism includes a correction arc seat symmetrically arranged above the ring clamp seat. A movable groove is provided within the correction arc seat, and a fixed column is provided within the movable groove. A movable column is slidably fitted within the movable groove, and the movable column and the fixed column are connected by a tensioning component. The tensioning mechanism includes a pulling component and a limiting component. The pulling assembly includes a vertically mounted rotating shaft on the mounting base. A rope roller is fixedly mounted on the upper end of the rotating shaft. A guide tube is provided on the side of the correction arc seat. The pull rope wound on the rope roller passes through the guide tube into the movable groove and connects to the movable column. The pulling assembly can pull the movable column to move within the movable groove. When correcting the fire pipe, the rope roller is rotated, and the pull rope pulls the movable column to move in an arc within the movable groove. When the movable column moves, it can push the fire pipe to gradually move towards the center of the floor slab sleeve, thus correcting the fire pipe. The limiting assembly includes a ratchet fixedly mounted on the lower end of the rotating shaft. A limiting lever is provided on the side of the mounting base. The stop pawl at the inner end of the limiting lever matches the ratchet. The limiting lever can limit the rotation of the ratchet.

[0006] Furthermore, a retaining ring is provided below the mounting base, and the limiting rod is slidably mounted on the lower part of the mounting base through the retaining ring. A pull plate is provided at the outer end of the limiting rod, and a reset component is mounted on the limiting rod.

[0007] Furthermore, the reset element is a compression spring connected between the pull plate and the insert ring.

[0008] Furthermore, the upper and lower end faces of the movable groove are provided with arc-shaped guide grooves, and the guide blocks connected to the upper and lower ends of the movable column are slidably fitted in the guide grooves, so that the movable column can slide stably in the movable grooves through the guide grooves.

[0009] Furthermore, the tension member is a tension spring connected between the movable column and the fixed column.

[0010] Furthermore, the inner diameter of the ring clamp is the same as the outer diameter of the through-floor sleeve.

[0011] Furthermore, the inscribed circle of the square formed by the movable column and the fixed column is exactly the outer diameter of the fire-fighting pipe.

[0012] Furthermore, a sleeve is fitted on the connecting rod on the other side.

[0013] The beneficial effects of this invention are as follows: By setting up a ring clamp, a correction mechanism, and a fixing mechanism, when correcting the deviation of the fire-fighting pipeline, the ring clamp is clamped on the outside of the through-sleeve, so that the fire-fighting pipeline is positioned between the two correction mechanisms. Then, the rope roller is rotated clockwise to wind up the pull rope, which pulls the movable column to move in the movable groove. When the movable column moves, it can push the fire-fighting pipeline towards the center of the through-sleeve. When the movable column and the fixed column form a square, the inner circle of the fixed column and the fixed column is exactly the outer diameter of the fire-fighting pipeline. At this time, the fire-fighting pipeline is pushed by the movable column to a position concentric with the through-sleeve, thus completing the correction and positioning of the fire-fighting pipeline. The operation process is very simple. After adjustment, the pipeline is in the center position, which improves the concentricity of the fire-fighting pipeline and the through-sleeve, avoids the fire-fighting pipeline from being eccentric, ensures the quality of the project, avoids subsequent rectification, and saves manpower and resources.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1-8 This invention provides a technical solution for controlling the concentricity of the installation pipe and sleeve: Example

[0025] according to Figure 1 and Figure 2 As shown, the ring clamp 1 includes a left arc-shaped clamp 11 and a right arc-shaped clamp 12. Connecting rods 5 extend symmetrically from the side walls of the left arc-shaped clamp 11 and the right arc-shaped clamp 12. A mounting seat 3 is provided on the side of the ring clamp 1. A set of connecting rods 5 on the right side is hinged to the mounting seat 3. When the left arc-shaped clamp 11 and the right arc-shaped clamp 12 are separated, as... Figure 6 As shown, a sleeve 8 can be fitted onto the connecting rod 5 on the left side. When the left arc-shaped clamp 11 and the right arc-shaped clamp 12 are closed together, the sleeve 8 can be fitted onto a set of connecting rods 5 on the left side, fixing the left arc-shaped clamp 11 and the right arc-shaped clamp 12 together. The inner diameter of the ring clamp 1 formed by the left arc-shaped clamp 11 and the right arc-shaped clamp 12 is consistent with the outer diameter of the through-floor sleeve 6. The through-floor sleeve 6 can be fitted into the ring clamp 1. Figure 3 and Figure 4 As shown, a correction mechanism 2 for correcting the deviation of the fire pipe 7 fitted inside the floor slab sleeve 6 is provided above the ring clamp 1. A correction arc seat 21 is symmetrically provided above the left arc-shaped clamp 11 and the right arc-shaped clamp 12. A movable groove 26 is matched within the correction arc seat 21, and a movable column 24 is provided within the movable groove 26. Arc-shaped guide grooves 23 are matched on the upper and lower end faces of the movable groove 26. Guide blocks are fixedly fitted at the upper and lower ends of the movable column 24. The movable column 24 slides within the guide groove 23 via the guide blocks. The guide groove 23 allows the movable column 24 to maintain a vertical and stable state when sliding within the movable groove 26. The movable column 24 and the fixed column 22 are connected by a tension member, which can be a tension spring 25. The tension spring 25 is an arc-shaped bending tension spring 25 matched with the movable groove 26. Through the tension of the tension spring 25, the movable column 24 is initially positioned close to the fixed column 22. Figure 7As shown, a tensioning mechanism 4 is provided on the side of the correction mechanism 2. The tensioning mechanism 4 includes a pulling assembly 41 for pulling the movable column 24 to move in an arc within the movable groove 26. A rotating shaft 43 is vertically mounted on the mounting base 3. A rope roller 413 is fixedly mounted on the upper end of the rotating shaft 43. Two pull ropes 412 are wound on the rope roller 413. A guide tube 411 is provided on the side of each of the two correction arc seats 21. The two pull ropes 412 are respectively guided into the movable groove 26 through the corresponding guide tubes 411. The end of the fixed column 24 is fixed to the corresponding movable column 24. When correcting the fire pipe 7, the rope roller 413 is rotated clockwise to wind up the pull rope 412. The pull rope 412 can pull the movable column 24 to move in an arc in the movable groove 26 and gradually move away from the fixed column 22. When the movable column 24 moves, it can push the fire pipe 7, so that the fire pipe 7 gradually moves towards the center position of the floor sleeve 6. When the movable column 24 moves to the rightmost end of the guide groove 23, the movable column 24 and the fixed column 22 form a square. Figure 8 As shown, the fixed column 22 and the inner circle of the fixed column 22 are exactly the outer diameter of the fire pipe 7. At this time, the fire pipe 7 is also pushed by the movable column 24 to a position concentric with the floor sleeve 6, completing the correction of the fire pipe 7, so that the axis of the fire pipe 7 and the axis of the floor sleeve 6 are coaxial. After the hole is completed, the sealing material is filled in, and then the device is removed. This device can be reused, and the operation process is very simple. The adjusted pipe is in the center position, avoiding the pipe from being eccentric, ensuring the quality of the project, avoiding the need for later rectification, and saving manpower and material resources.

[0026] like Figure 5 As shown, a limiting component 42 for limiting the rotation of the rope roller 413 is provided below the mounting base 3. A ratchet 421 is fixedly mounted on the lower end of the rotating shaft 43. The pawl of the ratchet 421 is tilted in the opposite direction to the rotation and winding direction of the rope roller 413. A stop pawl that cooperates with the ratchet 421 is provided below the mounting base 3. The stop pawl can limit the rotation direction of the ratchet 421, so that the ratchet 421 can only rotate clockwise and cannot rotate in the opposite direction. The ratchet 421 restricts the rope roller 413 to rotate clockwise to wind up the rope. The winding pull rope 412 pulls the movable column 24 to move away from the fixed column 22, pushing the fire pipe 7 to correct its deviation.

[0027] In practical use, the concentric device for controlling the installation of pipes and sleeves according to the present invention is snapped onto the part of the through-sleeve 6 that is above the ground, and the sleeve 8 is inserted into the left connecting rod 5. The ring clamp 1 formed by the left arc-shaped clamp 11 and the right arc-shaped clamp 12 are fixed to the outside of the through-sleeve 6. Then, the fire pipe 7 is sleeved inside the through-sleeve 6. Then, the rope roller 413 is rotated to drive the pull rope 412 to wind up. The pull rope 412 pulls the movable column 24 in the movable groove 26 to move away from the fixed column 22. When the movable column 24 moves, it can... Push the fire-fighting pipe 7 so that it gradually moves towards the center of the floor-penetrating sleeve 6. When the movable column 24 moves to the rightmost end of the guide groove 23, the inscribed circle of the square formed by the fixed column 22 and the fixed column 22 is exactly the outer diameter of the fire-fighting pipe 7. At this time, the fire-fighting pipe 7 is pushed by the movable column 24 to a position concentric with the floor-penetrating sleeve 6. The fire-fighting pipe 7 is now exactly coaxial with the floor-penetrating sleeve 6. Then, fill the gap between the fire-fighting pipe 7 and the floor-penetrating sleeve 6 with sealing material, and then remove the device to complete the concentric installation of the fire-fighting pipe 7 and the floor-penetrating sleeve 6. Example

[0028] Based on Example 1: such as Figure 5 As shown, a retaining ring 422 is fixed below the mounting base 3. A limiting rod 423 is fitted inside the retaining ring 422 and slides laterally. A pull plate 425 is provided at the outer end of the limiting rod 423, and a reset component is fitted on the limiting rod 423. The reset component can be a compression spring 424 connected between the pull plate 425 and the retaining ring 422. The stop pawl at the inner end of the limiting rod 423 matches the shape of the pawl groove of the ratchet 421. The limiting rod 423 is engaged with the ratchet 421. When the ratchet 421 rotates clockwise, due to the cooperation of the limiting rod 423 and the ratchet 421, the limiting rod 423 is engaged with the ratchet 421. The locking lever 423 can be pushed out from the front of the pawl, allowing the ratchet 421 to rotate clockwise smoothly. Simultaneously, under the elastic force of the compression spring 424, the locking lever 423 engages with the back of the pawl, restricting the rotation direction of the ratchet 421, ensuring it can only rotate clockwise. When it is necessary to release the pull rope 412, pull the locking lever 423 backward, completely disengaging it from the ratchet 421. At this point, under the tension of the tension spring 25, the movable column 24 can be pulled towards the fixed column 22. This tension drives the rope roller 413 to release the rope, causing the movable column 24 to return to its original position. Figure 7 The status shown is for future use.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
