Description

Technical Field

[0001] This utility model relates to the field of seismic support technology, specifically a seismic support for fire protection pipelines. Background Technology

[0002] Fire-fighting pipeline seismic bracing is a device specifically designed to limit the displacement and vibration of fire-fighting pipelines during earthquakes. Through components such as anchors, reinforcing hangers, seismic connection members, and diagonal braces, it firmly connects the pipeline system to the building structure, ensuring that it can transfer loads and maintain integrity during earthquakes, preventing pipeline breakage or detachment. The lateral support structure limits the lateral swaying of the pipeline during earthquakes, preventing pipeline detachment or damage to nearby facilities due to lateral forces.

[0003] As disclosed in the authorization announcement number CN218178131U, a fire-fighting pipeline seismic support includes a hoisting crossbeam, with suspension frames hinged at both ends of the hoisting crossbeam, rubber pads on the top surface of the hoisting crossbeam, and a support plate on the top surface of the rubber pads; a traction frame, movably inserted into the bottom surface of the hoisting crossbeam, with a clamping pressure plate at the top of the traction frame, clamping the fire-fighting pipeline between the clamping pressure plate and the support plate; and a threaded sleeve, located on the bottom plate of the traction frame, with an adjusting screw screwed inside the threaded sleeve, and a bearing seat fitted at the top of the adjusting screw, the bearing seat being fixed to the bottom surface of the hoisting crossbeam.

[0004] Although it achieves the effect of adding rubber pads and plates to the top surface of the hoisting crossbeam to support the fire pipeline, the traction frame pulls and clamps the pressure plate to tightly hold the fire pipeline, and the rubber pads are pressurized and elastically deformed, the rubber pads are located below the fire pipeline to play a shock absorption role.

[0005] However, this does not solve the problem that existing seismic bracing systems are generally not conducive to providing multiple buffer and shock absorption support for fire pipelines, making it difficult to conveniently install and fix the seismic bracing systems to the fire pipelines, thus affecting the ease of installation and disassembly of the seismic bracing systems and greatly impacting the convenience of using them.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a seismic-resistant support for fire-fighting pipelines, comprising a connecting plate and a fixing frame. A fixing frame is installed at the bottom of the connecting plate. Right drive arms are symmetrically and movably mounted on the outer wall of the fixing frame.

Left drive arms are symmetrically and movably mounted on the outer wall of the fixing frame on one side of the right drive arm. Left clamping arms are movably mounted on the outer wall of each left drive arm, and a limiting frame is movably connected to the left clamping arm via the main hinge shaft. A limiting block is installed on the outer wall of each left clamping arm, and a limiting arm is movably mounted on the outer wall of each limiting block. Fixing plates are symmetrically arranged on the outside of the connecting plate above the fixing frame. Each of the fixed plates has a symmetrically installed limit rod at its bottom end, extending to the outside of the connecting plate and slidably connected to it. A second spring damper is fitted onto the surface of each limit rod, with one end connected to the limit rod and the other end connected to the fixed plate. An upper connecting seat is installed at the bottom end of each fixed plate on one side of the limit rod. A reinforced spring damper is movably installed on the outer wall of each upper connecting seat. A drive shaft is installed on the outer wall of each upper connecting seat near the reinforced spring damper, connecting the upper connecting seat to the reinforced spring damper via the drive shaft. A lower connecting seat is installed on the outer wall of each connecting plate near the reinforced spring damper, with a drive shaft installed on the outer wall of each lower connecting seat near the reinforced spring damper, movably connecting the lower connecting seat to the reinforced spring damper via the drive shaft.

[0008] Preferably, each of the fixed frames near the left drive arm is equipped with a rotating shaft, and the fixed frame is movably connected to the left drive arm via the rotating shaft, and the fixed frame is also movably connected to the right drive arm via the rotating shaft.

[0009] Preferably, a left hinge shaft is installed on the outer wall of the left drive arm near the left clamping arm, and the left drive arm is movably connected to the left clamping arm through the left hinge shaft.

[0010] Preferably, a right hinge shaft is installed on the outer wall of the right drive arm near the right clamping arm, and the right drive arm is movably connected to the right clamping arm through the right hinge shaft. A flip shaft is installed on the outer wall of the limiting block near the limiting arm, and the limiting block is movably connected to the limiting arm through the flip shaft.

[0011] Preferably, the outer wall of each limiting arm is provided with multiple sets of limiting holes at equal intervals, and the outer side of the limiting arm on one side of the limiting block is provided with fixing bolts, which extend to the outside of the limiting holes.

[0012] Preferably, threaded holes are provided on the outer wall of the limiting block on one side of the fixing bolt, and the threaded holes are threadedly connected to the fixing bolt, and a fixing sleeve is installed at the bottom of the fixing frame.

[0013] Preferably, a threaded sleeve is movably mounted inside the fixed sleeve, and the threaded sleeve extends to the outside of the fixed sleeve.

[0014] Preferably, a threaded rod is installed at the top of the limiting frame below the threaded sleeve, and the threaded rod extends into the interior of the threaded sleeve and is threadedly connected to the threaded sleeve. A threaded block is fitted on the surface of the threaded rod on one side of the threaded sleeve, and the threaded block is threadedly connected to the threaded rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the seismic support not only realizes multiple buffer and shock absorption support for fire pipelines, reducing the vibration amplitude of fire pipelines to the outside and avoiding damage caused by long-term vibration of fire pipelines, but also facilitates the convenient installation and fixing of the seismic support for fire pipelines, and improves the convenience of installation and disassembly of the seismic support. By hoisting two sets of fixing plates into suitable positions, and placing the fire-fighting pipe between the two sets of right and left clamping arms, the threaded sleeve is manually rotated to facilitate the movement of the fixing frame under the threaded connection of the threaded rod and the movable support of the fixing sleeve. The fixing frame drives the right drive arm, right clamping arm, left drive arm, and left clamping arm to rotate, so that the two sets of right and left clamping arms can clamp and fix the fire-fighting pipe. When the fire-fighting pipe vibrates up and down, the connecting plate compresses multiple sets of second spring shock absorbers under the sliding support of the limit rod. The second spring shock absorbers provide elastic shock absorption support to the connecting plate through the limit rod. Meanwhile, with the fixed plate supporting multiple sets of upper connecting seats, the upper connecting seats support the reinforced spring shock absorber through the drive shaft, the reinforced spring shock absorber provides elastic shock absorption support to the lower connecting seat through the drive shaft, and the lower connecting seat provides elastic shock absorption support to the connecting plate. This facilitates the shock absorption of the fire pipeline in cooperation with the reinforced spring shock absorber and the second spring shock absorber, thereby reducing the vibration amplitude of the fire pipeline. This achieves multiple buffer and shock absorption support for the fire pipeline by the seismic brace, reducing the vibration amplitude of the fire pipeline to the outside and avoiding damage caused by long-term vibration of the fire pipeline. By manually rotating the threaded sleeve, under the movable support of the fixed sleeve and the threaded connection between the threaded sleeve and the threaded rod, the threaded sleeve drives the fixed sleeve to move, which in turn drives the fixed frame to move. The fixed frame, via a rotating shaft, drives the right drive arm to rotate. The right drive arm, via a right hinge shaft, drives the right clamping arm to rotate around the main hinge shaft. The limiting frame supports the main hinge shaft. Simultaneously, the fixed frame, via a rotating shaft, drives the left drive arm to rotate. The left drive arm, via a left hinge shaft, drives the left clamping arm to rotate around the main hinge shaft. This facilitates the convenient clamping and fixing of the fire-fighting pipe by the cooperation of the left and right clamping arms. After the fire-fighting pipe is clamped, the threaded block is manually rotated. Under the threaded connection between the threaded block and the threaded rod, the threaded block moves to the threaded sleeve. On one side, the connecting plate is conveniently locked and fixed to the threaded sleeve, preventing the threaded sleeve and threaded rod from loosening during vibration and affecting the clamping of the fire-fighting pipe. Two sets of limiting arms are manually rotated to allow the limiting arms to rotate around the flip axis to the surface of the fire-fighting pipe. The limiting block provides movable support for the flip axis. After the two sets of limiting arms are rotated to the appropriate position, the two sets of fixing bolts are manually rotated to allow the fixing bolts to pass through the limiting holes and be threaded into the threaded holes to fix the limiting arms to the surface of the limiting block. This facilitates convenient multi-level fixing of the fire-fighting pipe by the two sets of limiting arms, realizing convenient installation and fixing of the fire-fighting pipe by the seismic support, and improving the convenience of installation and disassembly of the seismic support.
