Description

Technical Field

[0001] This invention relates to the field of fire sprinkler pipe installation technology, and specifically to a fire sprinkler pipe support bracket. Background Technology

[0002] Fire sprinkler pipe supports are components used to fix and support fire sprinkler pipes. They ensure that the fire sprinkler pipe system is firm and stable, able to withstand its own weight, water pressure and external disturbances, and prevent the fire sprinkler pipes from shifting, sagging or vibrating. This ensures that the sprinkler heads are accurately positioned and that the water supply is unobstructed, so that the fire extinguishing system can function reliably and immediately in the event of a fire. It is a key guarantee for the effectiveness of the fire protection system.

[0003] For fire sprinkler pipe supports installed in factories, the seismic resistance requirements of fire sprinkler pipe supports are higher due to the influence of large vibrating equipment in the factory. In addition, factories require higher space utilization. Fire sprinkler pipes often need to run "side by side" with other fire sprinkler pipes with various functions and be laid out together. Therefore, their supports need to be able to meet the support functions of multiple fire sprinkler pipes at the same time.

[0004] During the daily operation of the factory, the existing fire sprinkler pipe supports lack the design to prevent unauthorized alterations. Changes may occur due to human factors, such as non-professionals loosening or adjusting pipe clamps at will, causing fire sprinkler pipes to fall off, leak, or change the direction of spraying, thereby affecting the normal operation of the fire protection system and emergency response capabilities, leaving serious safety hazards.

[0005] For example, patent document CN218739999U discloses a prefabricated support for fire sprinkler pipes, which is equipped with two sets of clamping mechanisms to clamp different fire sprinkler pipes. The pipes are clamped and fixed by turning the handwheel and knob. However, the two clamping mechanisms are fixed in the horizontal and vertical directions, which cannot flexibly adapt to the layout requirements of various fire sprinkler pipes. Furthermore, the handwheel and knob cannot restrict the operator, which may lead to non-professionals loosening the clamping mechanism at will and damaging the stable support of the fire sprinkler pipes. Summary of the Invention

[0006] The purpose of this invention is to provide a support bracket for fire sprinkler pipes to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A fire sprinkler pipe support includes a horizontal frame, a support assembly, a locking housing, a positioning seat, and pipe clamps.

The end of the moving iron core of the clamping push-pull electromagnet is fixedly connected to the corresponding push block, and the connecting rod is hinged to the corresponding connecting arm.

[0013] Furthermore, the support assembly also includes diagonal braces and telescopic connectors. Each support assembly has three diagonal braces and three telescopic connectors. The three diagonal braces are respectively located on the three outer periphery sides of the main support rod. The lower end of the diagonal brace is hinged to the lower end of the main support rod. The three telescopic connectors are respectively located between the corresponding diagonal brace and the main support rod. One end of the telescopic connector is hinged to the corresponding diagonal brace, and the other end of the telescopic connector is hinged to the side of the corresponding locking housing.

[0014] Furthermore, each of the main struts and the upper ends of each diagonal strut is connected to an installation assembly, which includes a connecting plate, an installation plate, and a shock-absorbing seat.

[0023] Furthermore, the technical fields and installation methods involved in the embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] Specific implementation examples Figures 1-9The fire sprinkler pipe support bracket includes a horizontal frame 1, a support assembly 2, a locking housing 3, a positioning seat 4, and a pipe clamping component 5. Two horizontal frames 1 are horizontally spaced vertically, and two support assemblies 2 are symmetrically arranged. The support assemblies 2 are foldable or expandable, and are respectively positioned on both sides of the horizontal frame 1. Each support assembly 2 includes a main support rod 21, and the locking housing 3 is sleeved on the main support rod 21, sliding along the main support rod 21 and being electromagnetically locked.

The positioning seats 4 can slide along the horizontal frame 1 and can be locked. Multiple pipe clamping parts 5 are provided. Each pipe clamping part 5 corresponds to a positioning seat 4. The pipe clamping part 5 is set inside the positioning seat 4 and includes two clamping clamps 51 that are set in pairs. The clamping clamps 51 are rotatably connected to the corresponding positioning seat 4. The lower parts of the two clamping clamps 51 are crossed and hinged. The two clamping clamps 51 can be locked by electromagnetic means. The upper parts of the two clamping clamps 51 are inserted into or separated.

[0025] Furthermore, the support assembly 2 also includes diagonal braces 22 and telescopic connectors 23. There are three diagonal braces 22 and three telescopic connectors 23. The three diagonal braces 22 are respectively arranged on the three outer periphery sides of the main support rod 21. The lower end of the diagonal brace 22 is hinged to the lower end of the main support rod 21. Each diagonal brace 22 is connected to the upper end of the main support rod 21 with an installation assembly 24.

This is used to enhance the vibration reduction effect of the support assembly 2 in the horizontal plane along the pipe axis and in the direction perpendicular to the pipe axis. In addition, when the support assembly 2 is installed after being unfolded, the telescopic connector 23 is used to position the diagonal brace 22 and the main brace 21, which facilitates installation and fixation.

[0027] Furthermore, a fixed insertion pipe 211 is fixedly installed on the lower end of the main support rod 21 near the horizontal frame 1. The fixed insertion pipe 211 is inserted into the horizontal frame 1 located below. The middle part of the main support rod 21 has a mating groove 213 on both the side near the horizontal frame 1 and the side away from the horizontal frame 1. The locking housing 3 has mating blocks 35 extending inward on both sides near the mating groove 213. The mating blocks 35 are mated with the mating groove 213 to increase the contact area between the locking housing 3 and the main support rod 21, making the connection between the locking housing 3 and the main support rod 21 more stable. A movable insertion pipe 31 is fixedly installed on the upper side of the locking housing 3 near the horizontal frame 1. The movable insertion pipe 31 is inserted into the horizontal frame 1 located above. The horizontal frame 1 located above can be adjusted in height as the locking housing 3 moves to adapt to the installation height requirements of different fire sprinkler pipes. Several reinforcing ribs 311 are provided between the lower side of the movable insertion pipe 31 and the locking housing 3 to increase the structural strength of the movable insertion pipe 31.

[0028] The main support rod 21 has locking racks 212 on both sides perpendicular to the side of the mating groove 213 for fixing the locking housing 3. The locking housing 3 has locking push-pull electromagnets 33 symmetrically installed on both sides perpendicular to the side of the mating block 35. A locking toothed plate 32 is fixedly connected to the end of the moving iron core of the locking push-pull electromagnet 33. The locking toothed plate 32 engages with the locking racks 212 through locking teeth. The locking housing 3 has locking clearance holes 34 on the side walls of both sides of the mating groove 213. The locking clearance holes 34 are coaxial with the moving iron core of the locking push-pull electromagnet 33. When the moving iron core of the locking mechanism 3 retracts, it passes into the locking clearance hole 34; when the locking push-pull electromagnet 33 is energized, the moving iron core of the locking push-pull electromagnet 33 retracts, the locking tooth plate 32 moves away from the locking rack 212, the locking tooth plate 32 separates from the main support rod 21, and the locking housing 3 unlocks and can slide along the main support rod 21; when the locking push-pull electromagnet 33 is de-energized, the moving iron core of the locking push-pull electromagnet 33 extends, the locking tooth plate 32 moves towards the locking rack 212 until the locking tooth plate 32 engages with the locking rack 212, the locking housing 3 locks with the main support rod 21, and the position of the locking housing 3 cannot be changed arbitrarily.

[0029] Furthermore, the horizontal frame 1 includes a C-shaped channel steel 11, a positioning rack 12, and a connecting block 13. Both ends of the C-shaped channel steel 11 are fixedly provided with connecting blocks 13.

The extension plates 41 are C-shaped, and their lower end faces abut against the outer surface of the C-shaped channel steel 11. A positioning toothed plate 43 is provided between each extension plate 41 and the support block 42. The lower part of the positioning toothed plate 43 extends into the C-shaped channel steel 11, and its lower part is provided with positioning teeth that engage with the positioning rack 12. A screw 44 is rotatably provided between the two extension plates 41. Above the C-shaped channel steel 11, the screw 44 passes through the extension plate 41, the positioning tooth plate 43, and the support block 42. The screw 44 is rotatably connected to the support block 42. The screw 44 has threads with opposite directions on both sides of the support block 42. The screw 44 is threadedly connected to the positioning tooth plate 43. One end of the screw 44 is provided with a flower-shaped locking slot 441. Using a special wrench that matches the shape of the locking slot 441, the screw 44 is rotated, and the positioning tooth plate 43 can move along the screw 44, thereby engaging or disengaging with the positioning rack 12, realizing the locking or unlocking of the positioning seat 4 and the horizontal frame 1. After the positioning seat 4 is locked on the horizontal frame 1, its position cannot be changed arbitrarily.

[0031] Furthermore, the clamping clamp 51 includes clamping arms 511. The upper ends of the two pairs of clamping arms 511 are respectively provided with insertion protrusions and insertion concave teeth. The insertion protrusions and insertion concave teeth are shaped to fit together for insertion, so that the two pairs of clamping arms 511 can engage and be fastened to the outer wall of the fire sprinkler pipe. In this embodiment, the two pairs of clamping arms 511 are semi-circular in shape, which can clamp a circular fire sprinkler pipe after being fastened. In other fire stations, the shape of the two pairs of clamping arms 511 can be square-ringed to clamp a square fire sprinkler pipe. The inner ring of the clamping arm 511 is provided with an inner liner 514. The inner liner 514 is an insulating material with a high coefficient of friction to prevent the clamping arms 511 from contacting the fire sprinkler pipe. The magnetic adsorption between the sprinkler pipes can increase the stability of the fire sprinkler pipe clamping; the lower end of the clamp arm 511 is fixedly connected to the connecting arm 512, and the two connecting arms 512 are arranged in pairs. The upper part of the positioning seat 4 is open, and the connecting arm 512 extends into the interior of the positioning seat 4. The middle part of the positioning seat 4 is fixedly provided with a support shaft 47. The two connecting arms 512 are rotatably connected to the support shaft 47 at the intersection. The lower end of the connecting arm 512 is fixedly provided with a guide rod 515 in the direction away from the clamp 51. The positioning seat 4 has arc-shaped guide grooves 45 on the inner walls at both ends of the support shaft 47. The guide rod 515 is inserted into the corresponding guide groove 45 and slides with it.

[0032] The pipe clamping component 5 further includes a clamping push-pull electromagnet 52, a push block 53, and a connecting rod 54. Two clamping push-pull electromagnets 52, push blocks 53, and connecting rods 54 are provided, with each corresponding to a connecting arm 512. The two clamping push-pull electromagnets 52 are respectively mounted on the side walls of the positioning seats 4 on both sides of the support shaft 47. The moving iron core end of each clamping push-pull electromagnet 52 is fixedly connected to the corresponding push block 53. The lower wall of the positioning seat 4 has grooves 46 on both sides of the support shaft 47. The lower end of each push block 53 is inserted into the corresponding groove 46 and slidably connected thereto. The positioning seat 4 has clamping clearance holes 48 on the side walls on both sides of the support shaft 47. The clamping clearance holes 48 are coaxial with the moving iron core of the clamping push-pull electromagnet 52. When the moving iron core of electromagnet 52 retracts, it passes into the corresponding clamping clearance hole 48. One end of connecting rod 54 is hinged to the lower end of the corresponding connecting arm 512, and the other end of connecting rod 54 is hinged to the side of push block 53. When the clamping push-pull electromagnet 52 is energized, the moving iron core of the clamping push-pull electromagnet 52 retracts, and push block 53 moves away from support shaft 47, causing the two connecting arms 512 to rotate in the direction of increasing angle. The two clamping clamps 51 separate, and fire sprinkler pipe can be installed. When the clamping push-pull electromagnet 52 is energized, the moving iron core of the clamping push-pull electromagnet 52 extends, and the two connecting arms 512 rotate in the direction of decreasing angle until the two clamping clamps 51 bite together, thereby fixing the fire sprinkler pipe in the clamping clamps 51. After the fire sprinkler pipe is fixed, the clamping clamps 51 cannot be opened arbitrarily.

[0033] In this embodiment, during installation, the locking push-pull electromagnet 33 is energized according to the required fixed position and arrangement of the fire sprinkler pipes. The locking housing 3 is moved along the main support rod 21 to the appropriate position and then de-energized. The position of the locking housing 3 is fixed and cannot be arbitrarily changed. The diagonal support rod 22 extends with the extension connector 23. The angle between the main support rod 21 and the diagonal support rod 22 can be adjusted and positioned according to installation requirements. The support assembly 2 is installed on the ceiling using the installation component 24. The main support rod 21 and the diagonal support rod 22 provide multi-point support, forming a triangular support structure that provides strong lateral rigidity support. Simultaneously, the connection is hinged, which, together with the extension connector 23, provides shock absorption and buffering effects. A special wrench is used to operate the screw 44. The positioning toothed plate 43 is separated from the positioning rack 12, and each positioning seat 4 is moved along the positioning rack 12 to the position corresponding to the fire sprinkler pipe to be fixed. The position of the positioning seat 4 is fixed and cannot be changed at will. The clamping push-pull electromagnet 52 is energized, the pair of clamping clamps 51 are separated, the fire sprinkler pipe is placed on the clamp arm 511 and then de-energized. The fire sprinkler pipe is fixed by the clamping clamp 51 and cannot be changed at will. In this embodiment, the height and horizontal position of the pipe clamp 5 are adjustable, which can limit and fix fire sprinkler pipes and other fire sprinkler pipes with different layouts. The installed pipe clamp 5 cannot be changed or opened without authorization, avoiding the damage to the fire sprinkler pipe support and hanger.
