Description

Technical Field

[0001] The utility model relates to the technical field of pipeline earthquake-resistant brackets, in particular to a four-way earthquake-resistant hoisting device for multiple pipelines. Background Art

[0002] In view of the great destructiveness of earthquakes, seismic performance is an important indicator that must be considered before construction, and the laying of pipes in buildings is an important factor affecting seismic performance. If the fixing of pipes does not meet the requirements, the falling pipes and their ancillary structures will cause huge casualties during earthquakes. After seismic reinforcement, the electromechanical engineering facilities such as water supply and drainage, fire protection, heating, ventilation, air conditioning, gas, heat, electricity, and communications in buildings can reduce earthquake damage, reduce and prevent secondary disasters as much as possible when encountering earthquakes with seismic fortification intensity in the region, thereby reducing casualties and property losses. Seismic brackets are used to limit the displacement of ancillary electromechanical engineering facilities, control the vibration of facilities, and transfer loads to various components or devices on the bearing structure. The invention patent with publication number CN116146791A discloses an earthquake-resistant support for building water supply and drainage pipes, which includes a bracket plate, a hanger assembly, a pipe clamp assembly and a support frame plate. The hanger assembly is installed at the four corners of the bracket plate, and the bracket plate is installed with a support frame plate and a pipe clamp assembly. The bottom end of the pipe clamp assembly is installed with a bottom support assembly, and side support assemblies are installed on both sides. A leakage monitoring system is composed of the pipe clamp assembly, a gel material, a pressure sensor, a controller, and a wireless communication module. When the flange joint of the building water supply and drainage pipe leaks, the gel material can absorb water and solidify. After solidification, the internal pressure increases and can be sensed by the adjacent pressure sensor, and an abnormal signal is sent to the controller, and the controller sends a leakage alarm to the background terminal; at the same time, after the gel material is solidified, the diffusion and leakage of the leakage can be avoided, which can buy time for maintenance and treatment. After the maintenance is completed, the gel material is updated and can be reused, but its structure is relatively complex, the manufacturing cost is high, and the practicality is relatively poor. Utility Model Content

[0003] The utility model aims to provide a four-way seismic lifting device for multiple pipes. The device has a simple and compact structure, can lift multiple pipes at the same time, has good supporting stability, strong seismic resistance, is easy to install and adjust, and has strong practicality.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A four-way seismic hoisting device for multiple pipelines, comprising a U-shaped bracket fixedly installed on a building structure. A plurality of pipeline brackets are detachably installed on the lower side of the U-shaped bracket. A first obliquely adjustable support rod and a second obliquely adjustable support rod are fixedly arranged on one side of the U-shaped bracket, and a third obliquely adjustable support rod and a fourth obliquely adjustable support rod are fixedly arranged on the other side of the U-shaped bracket. The first obliquely adjustable support rod and the third obliquely adjustable support rod form an inverted V-shaped support structure. The other ends of the first obliquely adjustable support rod, the second obliquely adjustable support rod, the third obliquely adjustable support rod and the fourth obliquely adjustable support rod are all connected to the building structure. The pipeline bracket includes a fastening connecting piece detachably connected to the U-shaped bracket, a support ring installed on the fastening connecting piece, a pressing ring detachably installed on the support ring, and a buffer gasket arranged inside the support ring and the pressing ring. The pipeline is arranged between the pressing ring and the support ring.

[0006] Preferably, the U-shaped bracket includes two vertically spaced parallel support rods and a horizontally support rod adjustably and fixedly installed between the two vertically support rods. The top of the vertically support rod is fixedly installed on the building structure through a T-shaped connecting piece.

[0007] Preferably, the fastening connecting piece and the support ring are hinged together through a U-shaped connecting piece.

[0008] Preferably, one or two horizontally support rods are arranged between the two vertically support rods.

[0009] Preferably, a limit switch is fixedly installed on the vertically support rod, and one end of the limit switch is in contact with the horizontally support rod.

[0010] Preferably, the first obliquely adjustable support rod, the second obliquely adjustable support rod, the third obliquely adjustable support rod and the fourth obliquely adjustable support rod have the same structure, including a channel steel, adjusting pieces adjustably installed at both ends of the channel steel, and an L-shaped connecting piece hingedly installed at one end of the adjusting piece. One end of the L-shaped connecting piece is connected to the building structure or the U-shaped bracket.

[0011] Preferably, a chute is arranged on the horizontally support rod, and the pipeline bracket is installed in the chute.

[0012] In the present utility model, the device can adjust the size of the U-shaped bracket according to the number of pipes to be hoisted, and is applicable to the hoisting operation of multiple pipes with strong applicability. The interval between adjacent two pipe brackets can be adjusted according to the pipe size and installation requirements. The first obliquely adjustable support rod, the second obliquely adjustable support rod, the third obliquely adjustable support rod, and the fourth obliquely adjustable support rod and the U-shaped bracket form a spatial structure, improving the stability of the support and having strong earthquake resistance. The provided U-shaped connecting piece can improve the adaptability of the device to different installation angles of the pipes, and the provided buffer washer can protect the pipes to prevent damage to the outer wall of the pipes caused by rigid connection. The provided limit switch can detect the installation position of the horizontal support rod in real time. When there is a problem of poor support force caused by the displacement of the horizontal support rod due to the loosening of the connection position, the limit switch can transmit this information to the control unit, and the inspection personnel can perform targeted maintenance according to this information, ensuring the safety of pipe hoisting.

The U-shaped bracket 2 includes two vertically supporting rods 20 arranged in parallel at intervals and a horizontally supporting rod 21 adjustably and fixedly installed between the two vertically supporting rods 20 through fasteners. The installation height of the horizontally supporting rod 21 on the two vertically supporting rods 20 is adjusted according to the installation requirements. The top of the vertically supporting rod 20 is fixedly installed on the top of the building structure 1 through a T-shaped connector 22. In specific implementation, one or two horizontally supporting rods 21 are arranged at intervals between the two vertically supporting rods 20 for installing different numbers of pipelines.

One end of the limit switch 4 is in contact with the horizontally supporting rod 21. The limit switch 4 is electrically connected to the controller of the central control unit. When the horizontally supporting rod 21 and the vertically supporting rod 20 generate displacement due to loose connection, the limit switch 4 transmits this displacement signal, enabling the monitoring personnel to quickly identify this dangerous information and perform targeted repairs. Of course, the limit switch 4 can also be replaced with a pressure sensor, and the maintenance personnel perform targeted repairs when the pressure of the pressure sensor changes significantly.

[0017] A plurality of pipeline brackets 3 are detachably installed on the lower side of the U-shaped bracket 2.
