Description

Technical Field

[0001] This utility model relates to the field of support and hanger technology, and specifically to a support and hanger with good seismic resistance. Background Technology

[0002] In building pipeline and equipment installation projects, supports and hangers are key components that bear the weight of pipelines and limit displacement. Their seismic performance is directly related to the safety and stability of pipeline systems under vibration environments such as earthquakes.

[0003] Among them, CN220366040U, a type of support and hanger, belongs to the field of building engineering. It includes a fixed plate, on the lower surface of which two clamping frames are fixedly mounted. The two clamping frames are rotatably fitted with four electric push rods and clamping clips. Six springs are fixedly mounted on the lower surface of the two clamping frames, and two clamping strips are fixedly mounted at the lower ends of the six springs. A motor is fixedly mounted on the upper surface of the fixed plate, and two gears are rotatably fitted at the output end of the motor. Two fixing strips that mesh with the two gears are slidably fitted on the fixed plate.

[0004] However, most existing supports and hangers adopt rigid fixed structures, which can only meet static load-bearing requirements. Rigid connections result in the transmission of vibration energy without attenuation. Stress concentration occurs at the connection between pipelines and supports and hangers due to resonance, leading to frequent occurrences of loose bolts and cracked welds. Utility Model Content

[0005] In view of the problems existing in the above-mentioned supports and hangers, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a support and hanger with good seismic resistance, which solves the problems that existing supports and hangers mostly adopt rigid fixed structures, which can only meet static load-bearing requirements, and the rigid connection leads to the transmission of vibration energy without attenuation. Stress concentration occurs at the connection between pipeline and support and hanger due to resonance, and bolt loosening and weld cracking occur frequently.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A seismic-resistant support bracket includes a support plate and two first fixing blocks. Hinges are provided on the upper surfaces of both ends of the support plate, and first support rods are hinged to both ends of the support plate via these hinges. Each of the two first fixing blocks has an internal cavity, and an annular plate is slidably disposed within each cavity. Second support rods are fixedly connected to the lower surfaces of both annular plates, and sealing holes are provided on the lower surfaces of both second support rods. The two second support rods are slidably and sealingly disposed within their respective sealing holes and are fixedly connected to the upper surfaces of the support plate. Third support rods are fixedly connected to the upper ends of both first fixing blocks, and second fixing blocks are sleeved on the walls of both third support rods. A fixing mechanism is provided at one end of each of the two second fixing blocks and the two first support rods.

[0009] Preferably, the fixing mechanism includes multiple mounting plates and multiple first bolts. Each mounting plate is fixedly connected to one end of a corresponding first support rod and each second fixing block. One end of each mounting plate is provided with a first mounting hole, and each first bolt is disposed inside the corresponding first mounting hole.

[0010] Preferably, the upper surfaces of both annular plates are provided with micropores.

[0011] Preferably, a sealing groove is provided on the outer surface of both annular plates, and an annular sealing ring is fixedly fitted inside the sealing groove.

[0012] Preferably, the lower surface of the second fixing block is provided with a sliding groove, and the two third support rods are respectively slidably disposed inside the corresponding sliding grooves. One side of each of the two sliding grooves is provided with an internal threaded hole, and a second bolt is provided inside each of the two internal threaded holes.

[0013] Preferably, each of the two third support rods has multiple slots on one side, and each slot is matched with the corresponding second bolt.

[0014] Preferably, a support block is fixedly connected to the upper surface of the support plate, and an arc-shaped groove is formed on the upper surface of the support block.

[0015] The advantages of this utility model are:

[0016] 1. The annular plate slides within the cavity of the first fixed block, and the annular sealing ring forms a sealed space. Air flows slowly through the micro-holes, generating damping, which consumes most of the longitudinal vibration energy and prevents the support from swaying due to vibration.

[0017] 2. By sliding the third support rod along the groove of the second fixed block and locking it with the second bolt and the multi-slot, the height of the mounting plate connected to it can be adjusted to accommodate the spacing between different building tops and pipelines.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] As Figure 1-3 The diagram shows a support bracket with good seismic resistance, comprising a support plate 1 and two first fixing blocks 2. Hinge seats 3 are provided on the upper surfaces of both ends of the support plate 1. First support rods 4 are hinged to both ends of the support plate 1 via the hinge seats 3. Each of the two first fixing blocks 2 has an internal cavity. An annular plate 5 is slidably disposed inside each of the two cavities. Second support rods 6 are fixedly connected to the lower surfaces of both annular plates 5. Sealing holes are provided on the lower surfaces of both second support rods 6. The two second support rods 6 are slidably disposed within their respective sealing holes and are fixedly connected to the upper surfaces of the support plate 1. Third support rods 7 are fixedly connected to the upper ends of both first fixing blocks 2. Second fixing blocks 8 are sleeved on the walls of both third support rods 7. Fixing mechanisms are provided at one end of each of the two second fixing blocks 8 and one end of each of the two first support rods 4. Micro-holes 11 are provided on the upper surfaces of both annular plates 5. Sealing grooves are provided on the outer surfaces of both annular plates 5. Annular sealing rings 12 are fixedly sleeved inside the sealing grooves.

[0025] When longitudinal vibration occurs, the support plate 1, under the weight of the pipeline and the vibration load, causes the second support rod 6 to move up and down, thereby pushing the annular plate 5 to slide within the cavity of the first fixed block 2. The annular sealing ring 12 on the outer surface of the annular plate fits tightly against the inner wall of the cavity, forming a sealed space. When the annular plate moves upward, the air below it is compressed and can only flow slowly upward through the micro-holes 11, generating an air damping effect and consuming most of the longitudinal vibration energy. When it moves downward, the air above flows back through the micro-holes, similarly forming a damping buffer and preventing structural damage caused by rigid impact.

[0026] To facilitate the installation of this hanger on the wall, such as Figure 1 As shown, the fixing mechanism includes multiple mounting plates 9 and multiple first bolts 10. Each mounting plate 9 is fixedly connected to one end of the corresponding first support rod 4 and each second fixing block 8. One end of each mounting plate 9 is provided with a first mounting hole, and each first bolt 10 is respectively disposed inside the corresponding first mounting hole.

[0027] Each first bolt 10 serves to secure the device, making it easy to install it in the designated location.

[0028] To facilitate adjustment of the distance between this support bracket and the top of the building, such as Figure 1-2 As shown, the lower surface of the second fixing block 8 is provided with a sliding groove, and the two third support rods 7 are respectively slidably disposed inside the corresponding sliding grooves. One side of each of the two sliding grooves is provided with an internal threaded hole, and the inside of each of the two internal threaded holes is provided with a second bolt 13. One side of each of the two third support rods 7 is provided with multiple slots, and each slot is matched with the corresponding second bolt 13.

[0029] The mounting plate 9, which is connected to the corresponding second fixing block 8, can slide on the inner wall of the groove by the third support rod 7, so that it can fit against the top of the building to install the device.

[0030] To support different pipe fittings, such as Figure 1 As shown, a support block 14 is fixedly connected to the upper surface of the support plate 1, and an arc-shaped groove is formed on the upper surface of the support block 14.

[0031] The support block 14 can be used to fit the outer surface of the pipe fitting, thus facilitating the fixing of the pipe fitting.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
