Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline fixing structure, specifically relating to a fire-fighting pipeline construction fixing structure. Background Technology

[0002] Fire protection pipelines are pipelines specifically designed for fire protection systems. They are mainly used to connect fire protection equipment and transport water or gas for fire extinguishing. When fire protection pipelines are constructed in various buildings such as residential, commercial, and industrial plants, existing technology usually uses fire protection pipeline fixing structures to fix them to the interior ceiling and walls of the building.

[0003] Chinese patent CN222416397U discloses a fire pipe fastener for fire protection engineering. The design includes a hanger with a pipe clamp installed at its bottom. A quick-release structure is provided between the hanger and the pipe clamp. The quick-release structure includes positioning holes, a lever, and slots. The positioning holes are symmetrically located on both sides of the bottom of the hanger. The lever is located on one side of the positioning holes at the bottom of the hanger. The slots are evenly distributed on both sides of the pipe clamp. Both the hanger and the pipe clamp are U-shaped. The design involves inserting both ends of the pipe clamp downwards into the positioning holes, and using the anti-slip rubber on the inner side of the pipe clamp to abut and fix the fire pipe against the pipe wall. The lever prevents the pipe clamp from moving upwards, thereby fixing the fire pipe.

[0004] When using the above solution, because the positioning holes are symmetrically opened at the bottom of the hanger, the spacing of the positioning holes is fixed, which means that the above solution can only fix fire pipes of a single size, and the applicable scenarios are relatively limited. Utility Model Content

[0005] The present invention aims to provide a fixed structure for fire protection pipeline construction to solve the problem that the above-mentioned solutions have limited applicable scenarios.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fire-fighting pipeline construction fixing structure includes an installation frame, a drive assembly, and a U-shaped clamp. Vertical rods are fixedly installed at the left and right ends of the top of the installation frame. A through groove is symmetrically formed between the two vertical rods at the top of the installation frame. A slider is slidably installed along the length of each through groove. A vertically extending limiting groove is formed on each slider. The drive assembly is located within the installation frame and is used to drive the two sliders to move towards or away from each other. Two vertical sections of the U-shaped clamp are slidably inserted into the corresponding limiting grooves. A ratchet is provided on the inner wall of each of the two vertical sections of the U-shaped clamp. A limiting block that rotatably engages with the ratchet is rotatably provided on the inner wall of the limiting groove. A guide ramp is provided on the top of the limiting block near the end of the ratchet.

[0008] The principle and effects of this technical solution:

[0009] During installation, the vertical rods are first fixed to the inner top wall of the building using expansion bolts. Then, the fire-fighting pipe is placed between the two vertical rods on top of the mounting frame. Next, the U-shaped hoop is fitted onto the top of the fire-fighting pipe. Then, the two sliders are moved in opposite directions using the drive assembly so that the limiting grooves on the two sliders are aligned with the vertical section of the U-shaped hoop. When the vertical section of the U-shaped hoop is inserted into the limiting groove, the ratchet can push the limiting block to rotate. After the U-shaped hoop clamps the fire-fighting pipe with the mounting frame, the bottom of the limiting block can prevent the U-shaped hoop from moving upward.

[0010] By adjusting the distance between the two sliders using the drive assembly, U-shaped clamps of various radii can be inserted into the limiting grooves on the sliders, thereby enabling the device to fix fire pipes of various sizes, improving the applicability of the device and solving the problem of the limited application scenarios of the above-mentioned solutions.

[0011] In this invention, the driving assembly includes a bidirectional screw rod rotatably inserted into the two through slots, and two sliders respectively fitted onto the positive and negative threaded sections of the bidirectional screw rod. A guide rod is fixedly arranged laterally within each through slot, and the slider is also slidably fitted onto the corresponding guide rod. Through this arrangement, by rotating the bidirectional screw rod, the two sliders can be moved towards or away from each other.

[0012] In this utility model, a height adjustment component is also included. The top of the mounting bracket is provided with a slot between the two through slots. The height adjustment component includes a movable seat whose bottom is slidably inserted into the slot. A threaded rod is rotatably disposed in the slot. The bottom of the movable seat is fitted with the threaded section of the threaded rod.

[0013] The principle and effects of this technical solution:

[0014] Before placing the fire-fighting pipe, the movable seat is restricted from rotating by the slot. The movable seat is moved up and down by rotating the threaded rod. When placing the fire-fighting pipe, the fire-fighting pipe is placed on top of the movable seat. When it is necessary to remove the installed U-shaped clamp, first use the rotating threaded rod to move the movable seat down. The fire-fighting pipe moves down with it, and a gap appears between the U-shaped clamp and the fire-fighting pipe. Manually rotate the limiting block to disengage the limiting block from the ratchet rack. At this time, the U-shaped clamp can slide upward.

[0015] The above settings allow for fine-tuning of the installation height of fire-fighting pipes and facilitate the installation and removal of U-shaped clamps by staff.

[0016] In this invention, the inner wall of the limiting groove is provided with a groove, and a fixed shaft is arranged laterally within the groove. The top of the limiting block is rotatably sleeved on the fixed shaft, and a torsion spring is wound around the fixed shaft. One torsion arm of the torsion spring is connected to the limiting block, and the other torsion arm of the torsion spring abuts against the inner top wall of the groove. Through the above arrangement, the elastic force of the torsion spring pushes the limiting block to engage with the ratchet rack, improving the stability and safety of the device during use.

[0017] In this invention, the inner bottom wall of the groove is provided with a vertically penetrating sliding groove, and a lever that slides through the sliding groove is fixedly installed at the bottom of the limiting block. This design facilitates the rotation of the limiting block by the operator, improving the operability of the device.

[0018] In this invention, the top of the movable seat is provided with a V-shaped groove. This design allows for lateral restraint of fire-fighting pipes during installation, facilitating the installation of U-shaped clamps by workers.

[0019] In this invention, an anti-slip rubber pad is fixedly installed on the inner side wall of the slot. This design prevents the outer wall of the fire-fighting pipe from colliding with the movable seat, thus avoiding damage to the paint, and also increases the friction between the fire-fighting pipe and the movable seat.

[0026] Example:

[0027] As attached Figure 1-4As shown, this utility model discloses a fire pipeline construction fixing structure, including a mounting frame 10, a driving component, and a U-shaped hoop 40. Vertical rods 11 are fixedly installed at the left and right ends of the top of the mounting frame 10. A through groove 12 is symmetrically opened between the two vertical rods 11 at the top of the mounting frame 10. A slider 20 is slidably installed in the through groove 12 along its length direction. A vertically extending limiting groove 21 is opened in the slider 20. The driving component is installed in the mounting frame 10 and is used to drive the two sliders 20 to move towards or away from each other. The two vertical sections of the U-shaped hoop 40 are slidably inserted into the corresponding limiting grooves 21. A ratchet 41 is provided on the inner sidewall of the two vertical sections of the U-shaped hoop 40. A limiting block 50 that cooperates with the ratchet 41 is rotatably installed on the inner sidewall of the limiting groove 21. A guide slope is provided on the top of the limiting block 50 near the end of the ratchet 41.

[0028] In this embodiment, the driving assembly includes a bidirectional screw 31 rotatably inserted into the two through slots 12, and two sliders 20 respectively fitted onto the positive and negative threaded sections of the bidirectional screw 31. Guide rods 13 are fixedly arranged in the through slots 12 along the transverse direction, and the sliders 20 are also slidably fitted onto the corresponding guide rods 13.

[0029] In this embodiment, a height adjustment component is also included. The top of the mounting bracket 10 is provided with a slot 14 between the two through slots 12. The height adjustment component includes a movable seat 61 whose bottom is slidably inserted into the slot 14. A threaded rod 62 is rotatably disposed in the slot 14. The bottom of the movable seat 61 is fitted with the threaded rod segment of the threaded rod 62.

[0030] In this embodiment, the inner wall of the limiting groove 21 is provided with a groove 22, and a fixed shaft 23 is provided horizontally inside the groove 22. The top of the limiting block 50 is rotatably sleeved on the fixed shaft 23. A torsion spring 70 is wound around the fixed shaft 23. One torsion arm of the torsion spring 70 is connected to the limiting block 50, and the other torsion arm of the torsion spring 70 abuts against the inner top wall of the groove 22.

[0031] In this embodiment, the inner bottom wall of the groove 22 is provided with a vertically penetrating sliding groove 24, and the bottom of the limiting block 50 is fixedly provided with a lever 51 that slides through the sliding groove 24.

[0032] In this embodiment, the top of the movable seat 61 is provided with a V-shaped slot.

[0033] In this embodiment, an anti-slip rubber pad 63 is fixedly provided on the inner side wall of the slot.

[0034] The specific implementation process is as follows:

[0035] During installation, the vertical rod 11 is first fixed to the inner top wall of the building using expansion bolts. Then, the fire pipe 80 is placed between the two vertical rods 11 on top of the mounting frame 10. Next, the U-shaped clamp 40 is fitted onto the top of the fire pipe 80. Then, the two sliders 20 are moved in opposite directions or back to back using the drive assembly so that the limiting grooves 21 on the two sliders 20 are aligned with the vertical section of the U-shaped clamp 40. When the vertical section of the U-shaped clamp 40 is inserted into the limiting groove 21, the ratchet 41 can push the limiting block 50 to rotate. After the U-shaped clamp 40 clamps the fire pipe 80 with the mounting frame 10, the bottom of the limiting block 50 can prevent the U-shaped clamp 40 from moving upward.

[0036] Before placing the fire pipe 80, the movable seat 61 is restricted from rotating by the slot 14. The movable seat 61 is moved up and down by rotating the threaded rod 62. When placing the fire pipe 80, the fire pipe 80 is placed on top of the movable seat 61. When it is necessary to remove the installed U-shaped clamp 40, the movable seat 61 is first moved down by rotating the threaded rod 62. The fire pipe 80 moves down accordingly, and a gap appears between the U-shaped clamp 40 and the fire pipe 80. The limiting block 50 is manually rotated to disengage the limiting block 50 from the ratchet rack 41. At this time, the U-shaped clamp 40 can slide up.
