Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline fixing equipment, specifically, it relates to a hanging pipeline rack. Background Technology

[0002] Pipe supports are crucial support components in piping systems, playing a key role when pipes are installed along walls, columns, or overhead. Through a scientifically designed structure, they provide stable support and reliable fixation for pipelines, ensuring they maintain the correct position and orientation during operation. This prevents displacement, deformation, or swaying due to factors such as weight, fluid pressure, and temperature changes, thus guaranteeing the safe and stable operation of the entire piping system. Common types of pipe supports include sliding supports, fixed supports, guide supports, and hangers. Sliding supports allow the pipe to slide axially within a certain range, accommodating length changes caused by thermal expansion and contraction. Fixed supports firmly fix the pipe in a designated position, preventing movement in any direction. Guide supports primarily restrict lateral displacement while allowing axial movement. Hangers, also known as suspended pipe supports, are widely used in pipeline installation due to their unique installation method and excellent applicability.

[0003] Currently, when fixing and supporting pipelines, commonly used suspended pipe supports are mostly U-shaped pipe brackets composed of hangers and bottom angle irons. These supports are generally installed on the lower side of the structure, suspending the pipeline for fixation via the hangers. Structurally, U-shaped pipe supports are simple to construct and easy to install, quickly completing the hoisting and fixing of pipelines, and basically meeting pipeline support requirements. However, this single U-shaped pipe support structure has increasingly revealed problems in practical use. Its rigid fixing method is inadequate when facing the complex operating conditions of pipelines. When fluid flows inside the pipeline, the pressure at the fluid head generates impacts, causing pipeline vibration. Rigidly fixed pipe supports cannot effectively buffer and absorb vibration energy, and the vibration is directly transmitted to the pipe support and the pipeline. Long-term exposure to this vibration environment can easily lead to loosening and fatigue fracture at the pipe support connections, and the pipeline itself may also suffer damage such as cracks and deformation due to repeated vibration, seriously affecting the service life and safety of the pipeline system. Therefore, it is clear that traditional rigid fixing methods cannot provide stable and reliable support for pipeline operation and are insufficient to meet the high requirements of modern pipeline systems for safety and stability.

[0004] Based on this, the present invention proposes a hanging pipe rack to solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the main purpose of this utility model is to provide a suspended pipe rack to solve the problems of existing suspended pipe racks that cannot effectively buffer and absorb vibration energy, cannot provide stable and reliable support for pipeline operation, and cannot meet the high requirements of modern pipeline systems for safety and stability.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A pipe hanger includes a fixing clamp that matches the pipe to be hung and fixed; a vertical hanger and an auxiliary hanger are also provided at the upper end of the fixing clamp, the vertical hanger is vertically connected to the fixing clamp, and the auxiliary hanger is eccentrically connected to the fixing clamp; a buffer assembly is installed at the end of the vertical hanger and the auxiliary hanger near the positioning connecting plate, and the buffer assembly matches the positioning connecting plate.

[0008] In a preferred embodiment, the fixing hoop includes two symmetrically arranged matching arc-shaped positioning clips, which are arc-shaped steel sheet structures and are connected by clamping bolts.

[0009] In a preferred embodiment, the positioning clip is further provided with a protruding connecting back rib in the middle, and a slot is formed on the inner side of the positioning clip at the location of the connecting back rib.

[0010] In a preferred embodiment, a plurality of connecting holes are provided on the connecting back rib, and the connecting holes are connected to the connecting rings of the auxiliary rod.

[0011] In a preferred embodiment, the fixing hoop further includes a transition bolt, which is connected to the positioning clip, and a sleeve is fitted on the outside of the transition bolt between the two ear plates to rotatably connect with the vertical hanger.

[0012] In a preferred embodiment, both the vertical boom and the auxiliary boom include a connector and a tie rod. The tie rod is threadedly connected to the connector, and the other end of the tie rod of the vertical boom is connected to a sleeve. The other end of the tie rod of the auxiliary boom is connected to a connecting ring and a buffer assembly, respectively.

[0013] In a preferred embodiment, the vertical boom further includes a threaded rod located at the upper end of the connector, one end of which is threadedly connected to the buffer assembly and the other end of which is threadedly connected to the connector.

[0014] In a preferred embodiment, the buffer assembly includes a housing, a buffer element, and a prestressed nut; the housing is fitted to a positioning connecting plate; the buffer element is mounted inside the housing by a spring and extends to the underside of the housing, connecting to a threaded rod and a tie rod; the prestressed nut is threadedly connected to the buffer element extending into the housing.

[0015] In a preferred embodiment, the rear end of the outer casing is provided with a tail plate, which matches the central clearance hole of the positioning connecting plate.

[0016] In a preferred embodiment, the buffer includes a connecting ring, a pressure plate, and a connecting rod; the connecting ring is located at the lower end of the connecting rod and is connected to a threaded rod and a pull rod respectively; the pressure plate is movably disposed within the housing, and guide blocks are symmetrically disposed on the connecting ring to match the sliding grooves disposed on the side wall of the housing; the connecting rod is located between the connecting ring and the pressure plate and is threadedly connected to a prestressed nut.

[0017] Compared with the prior art, the present invention provides a hanging pipe rack, which has the following advantages:

[0018] 1. This suspended pipe rack utilizes the collaborative action of multiple components to construct an extremely stable structure. The fixing clamps employ an arc-shaped steel plate structure, which fits snugly against the outer wall of the pipe. Connecting bolts pass through the connecting holes on the end ears and are tightened, achieving a reliable connection between the positioning clamps and providing a stable clamping and fixing foundation for the pipe. The vertical hanger consists of a threaded rod, connector, and tie rod. The threaded connection ensures that all components are tightly linked, forming a powerful load-bearing structure. The tie rods of the auxiliary hanger are symmetrically positioned at both ends of the connector, respectively connected to the lifting ring and the buffer assembly. They provide support in the eccentric direction of the fixing clamp, effectively preventing the pipe from shaking or being damaged due to eccentric force. The positioning connection plate provides a stable installation foundation for the entire system, ensuring accurate positioning and reliable connection of each component. Together, they guarantee the strong load-bearing capacity of the suspended pipe rack, making the pipe rack structure stable, with a high load-bearing capacity, and capable of safely and stably supporting various pipelines.

[0019] 2. Through the design of the buffer assembly, the springs within the outer casing work in conjunction with the pressure plate. When the pipeline is subjected to gravity or other external forces, the springs undergo elastic deformation under the action of the pressure plate and connecting rod, absorbing and dispersing part of the external force, greatly reducing the impact on the building structure. The prestressed nut can be adjusted on the buffer component to apply prestress to the spring, further enhancing the buffering effect. The buffering performance can be flexibly adjusted according to different usage requirements and stress conditions, effectively protecting the pipeline and building structure from damage. This solves the problems of existing suspended pipe racks, which cannot effectively buffer and absorb vibration energy, cannot provide stable and reliable support for pipeline operation, and cannot meet the high safety and stability requirements of modern pipeline systems.

[0035] As per the instruction manual Figures 1-7 As shown, this utility model provides a technical solution:

[0036] A pipe rack includes a fixing clamp 1, which is matched with the pipe to be hung and fixed, and is used to clamp and fix the pipe to ensure its stability. A vertical hanger and an auxiliary hanger are also configured at the upper end of the fixing clamp 1. The vertical hanger is vertically connected to the fixing clamp 1 and mainly undertakes the task of vertically fixing the fixing clamp 1, providing stable vertical support for the pipe. The auxiliary hanger is eccentrically connected to the fixing clamp 1, which can assist in fixing the fixing clamp 1 and effectively prevent uncontrollable swinging of the fixing clamp 1 during use, ensuring the stability of pipe operation. A buffer assembly 4 is installed at the tail end of both the vertical hanger and the auxiliary hanger. The buffer assembly 4 works in conjunction with a positioning connecting plate 5. The positioning connecting plate 5 is installed on the underside of the floor slab by positioning bolts 6, thereby achieving a stable connection between the entire pipe rack and the floor structure.

[0037] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the fixing clamp 1 includes two symmetrically arranged, mutually matching arc-shaped positioning clips 11, which are connected by clamping bolts 12. When the clamping bolts 12 are tightened, the two arc-shaped positioning clips 11 gradually approach each other and press against each other, which can match pipes of different diameters, and finally form a complete annular fixing clamp, thereby achieving reliable clamping and fixing of the pipe to be suspended, ensuring that the pipe will not loosen or shift during the suspension process.

[0038] Specifically, the positioning clamp 11 is an arc-shaped steel sheet structure that can adapt to the pipe to be suspended and fixed during use, closely fitting the outer wall of the pipe and providing a foundation for subsequent stable clamping. Furthermore, the ear plates at both ends of the positioning clamp 11 are specially provided with connecting holes. These connecting holes are used in conjunction with connecting bolts 12. By passing the connecting bolts 12 through the connecting holes and tightening them, a reliable connection between the positioning clamps 11 can be achieved, thereby completing the clamping and fixing of the pipe and ensuring the overall effectiveness of the suspended pipe rack.

[0039] More specifically, a protruding connecting back rib 111 is provided in the middle of the positioning clamp 11. A slot 112 is naturally formed on the inner side of the positioning clamp 11 at the location of the connecting back rib 111. Several connecting holes are provided on the connecting back rib 111, which are used to connect with the connecting ring 3 of the auxiliary lifting rod. In actual use, with the cooperation of the connecting back rib 111 and the slot 112, the connecting ring 3 can be installed on the outer side of the positioning clamp 11 at the location of the connecting back rib 111, thus forming a force-bearing point during the installation of the auxiliary lifting rod and ensuring that the auxiliary lifting rod can function stably.

[0040] Specifically, the fixing clamp 1 also includes a transition bolt 13, which is connected to the ear plate at the upper end of the positioning clamp 11. A sleeve 14 is also sleeved on the outside of the transition bolt 13 between the two ear plates and is rotatably connected to the vertical hanger. The sleeve 14 can be rotatably connected to the vertical hanger, allowing the vertical hanger to have a certain amount of room to move when under force, reducing the stress concentration problem caused by rigid connection, and enhancing the stability and flexibility of the entire hanging pipe rack.

[0041] In a preferred embodiment, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the vertical suspension rod includes a threaded rod 2, a connector 7, and a pull rod 8. The threaded rod 2 is located at the upper end of the connector 7 and features a double-threaded connection. One end is threadedly connected to the buffer assembly 4, thus achieving a stable connection with the upper structure; the other end is threadedly connected to the connector 7, tightly fixing itself to the connector 7. The pull rod 8 is located at the lower end of the connector 7. One end is rotatably connected to the sleeve 14, allowing the pull rod 8 to rotate flexibly relative to the sleeve 14; the other end is also threadedly connected to the connector 7. In actual use, the operator only needs to rotate the connector 7 to easily adjust the overall height of the vertical suspension rod, thereby achieving precise adjustment of the height of the fixing hoop 1 to meet the needs of different installation scenarios.

[0042] Specifically, the pull rod 8 is a pull rod structure with a collar at the end, which is rotatably connected to the sleeve 14.

[0043] In a preferred embodiment, such as Figure 1 , Figure 4 and Figure 5 As shown, the auxiliary suspension rod includes a connector 7 and a pull rod 8. The pull rod 8 is symmetrically arranged at both ends of the connector 7 and is threadedly connected to the connector 7. The pull rod 8 located at the lower end of the connector 7 is movably connected to the lifting ring 3, and the pull rod 8 located at the upper end of the connector 7 is movably connected to the buffer assembly 4. This allows the auxiliary suspension rod to provide reliable support force to the fixing hoop 1 in the eccentric direction, thereby enhancing the stability of the entire suspension structure.

[0044] In a preferred embodiment, such as Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the buffer assembly 4 includes a housing 41, a buffer element 42, and a prestressed nut 43. A tail plate 411 is integrally formed at the tail end of the housing 41. The tail plate 411 engages with the central clearance hole of the positioning connecting plate 5. This engagement allows for a convenient and quick secure connection between the housing 41 and the positioning connecting plate 5, providing reliable support for the entire suspension system. The buffer element 42 is installed inside the housing 41 via a spring 44 and extends to the lower side of the housing 41, connecting to the threaded rod 2 (threaded connection) and the pull rod 8 (fitting connection). The prestressed nut 43 is connected to the buffer element 42 extending into the housing 41 and is used to apply prestress to the spring 44 by adjusting its position on the buffer element 42, thereby better adapting to different usage requirements and stress conditions.

[0045] Specifically, the buffer component 42 includes a connecting ring 421, a pressure plate 423, and a connecting rod 424. The connecting ring 421 is located at the lower end of the connecting rod 424 and is connected to the threaded rod 2 (threaded connection) and the pull rod 8 (fitting connection) respectively, thereby achieving a stable connection with other components of the suspension system. The pressure plate 423 is movably installed inside the outer casing 41, and guide blocks 422 are symmetrically arranged on the connecting ring 421 to cooperate with the sliding grooves 412 provided on the side wall of the outer casing 41, extending to the outside of the sliding grooves 412, so as to guide the movement of the pressure plate 423 during use and prevent it from eccentric movement. The connecting rod 424 is located between the connecting ring 421 and the pressure plate 423 and is threadedly connected to the prestressed nut 43. The stress on the relevant components can be adjusted by adjusting the prestressed nut 43.

[0046] Specifically, the spring 44 is located below the pressure plate 423 and works in conjunction with the pressure plate 423. During the operation of the buffer assembly 4, the spring 44, with its own elastic properties, works in synergy with the pressure plate 423 to effectively buffer and disperse the external forces received by the suspension system, thereby ensuring the stable operation of the entire system.

[0047] The construction process and implementation principle of the suspended pipeline rack described in this utility model include:

[0048] During the installation of the suspended pipe rack, the installation position of the positioning connection plate 5 is first determined on the building structure according to the design location of the pipe and the suspension requirements. Next, the tail plate 411 of the buffer assembly 4 is aligned with and fixed to the middle clearance hole of the positioning connection plate 5. After completing the connection between the buffer assembly 4 and the positioning connection plate 5, the positioning connection plate 5 is installed in the corresponding position. Then, the threaded rod 2 of the vertical hanger is threaded to the buffer assembly 4, and the connector 7 is tightened to the other end of the threaded rod 2. The pull rod 8 is then threaded to both ends of the connector 7, so that the pull rod 8 at the lower end of the connector 7 is movably connected to the lifting ring 3, and the pull rod 8 at the upper end is further fitted and connected to the buffer assembly 4. Subsequently, auxiliary hangers are installed, with the pull rods 8 symmetrically positioned at both ends of the connector 7 and threaded together, ensuring that the lower pull rod 8 is movably connected to the lifting ring 3 and the upper pull rod 8 is movably connected to the buffer assembly 4. Finally, install the fixing clamp 1, attach the positioning clip 11 to the pipe, and use the connecting bolt 12 to pass through the connecting holes on the ear plates at both ends of the positioning clip 11 and tighten it to complete the clamping and fixing of the pipe. At the same time, use the adapter connecting bolt 13 to rotate and connect the fixing clamp 1 to the sleeve 14 of the vertical hanger.

[0049] When this suspended pipe rack is in use, if the pipe is subjected to gravity or other external forces, the fixing clamp 1 transmits the force to the vertical hanger and auxiliary hanger. The threaded rod 2, connector 7, and tie rod 8 in the vertical hanger form a stable load-bearing structure, transmitting the force to the buffer assembly 4. The spring 44 in the buffer assembly 4 undergoes elastic deformation under the action of the pressure plate 423 and connecting rod 424, absorbing and dispersing part of the external force and reducing the impact on the building structure. The prestressed nut 43 can apply prestress to the spring 44 by adjusting its position, enhancing the buffering effect. The auxiliary hanger provides support in the eccentric direction of the fixing clamp 1, preventing the pipe from shaking or being damaged due to eccentric force. At the same time, the positioning connecting plate 5 provides a stable installation foundation for the entire suspension system, ensuring accurate positioning and reliable connection of each component, thereby ensuring that the suspended pipe rack can safely and stably support the pipe.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
