Description

Technical Field

[0001] This utility model relates to the technical field of pipeline support equipment, and specifically discloses a pipeline seismic support with excellent seismic resistance. Background Technology

[0002] In building electromechanical engineering, the seismic safety of piping systems (such as water pipes, air ducts, and cable trays) is crucial. Traditional pipe supports often employ simple rigid fixing methods, such as using angle steel or channel steel with U-bolts to directly fix the pipes. This structure has significant drawbacks: First, its clamping space is fixed, only suitable for a single pipe diameter. When encountering different types of pipes in a project, multiple specifications of supports are required, leading to complex inventory management, low installation efficiency, and high costs. Second, when an earthquake occurs, this rigid connection cannot effectively absorb and dissipate seismic energy, easily causing the pipe and support to collide hard, resulting in localized stress concentration and damage to the pipe, or even causing the support itself to loosen and fall off, triggering secondary disasters.

[0003] To address the aforementioned issues, some improved seismic bracing techniques have emerged in the prior art. For example, perforated C-shaped steel with spring nuts allows for some longitudinal height adjustment, or rubber gaskets are added between the bracing and the pipe to provide minor cushioning. However, these improvements still have significant shortcomings: First, the opening size of their clamping mechanisms and the cushioning components are often fixed. Although the height is adjustable, they are difficult to effectively adapt to situations with large differences in pipe diameter, and the problem of poor versatility remains unresolved. Second, they primarily buffer vibrations in a single direction (usually vertical), and their damping effect is limited for complex seismic waves (multi-directional, multi-frequency). Third, the clamping parts are still mostly rigid or semi-rigid contacts, which cannot effectively suppress lateral swaying and torsion of the pipe, and the design for the dispersion and transmission path of impact loads is insufficient, resulting in weak energy dissipation capacity.

[0004] Therefore, there is an urgent need in this field for a new type of support that combines excellent versatility with superior seismic resistance. An ideal solution should be able to flexibly adapt to pipes of different models and diameters within a certain range, reduce the types of spare parts, and simultaneously provide multi-directional buffering, effective energy dissipation, and stable clamping to comprehensively improve the seismic safety and economy of pipeline systems. Utility Model Content

[0005] This utility model proposes a pipeline seismic support with excellent seismic resistance. Through the synergistic effect of the V-shaped support body and the upper and lower double elastic clamping system, it not only significantly improves the seismic safety of pipelines, but also has multiple beneficial effects such as universal compatibility, pipeline protection, convenient installation and economic efficiency.

[0006] This utility model is implemented as follows: a seismic-resistant pipe support with excellent seismic performance includes a support body, which is a V-shaped structure with the opening facing upwards. The support body is integrally formed by a horizontal bottom beam and two inclined support arms symmetrically fixed at both ends of the horizontal bottom beam. The top of the two inclined support arms is provided with a horizontally outwardly extending fixed wing plate, and the fixed wing plate is provided with mounting holes. A first elastic pad is provided on the inner sidewall of the two inclined support arms facing each other. An auxiliary pipe clamping assembly is provided in the middle of the top surface of the horizontal bottom beam, and a main pipe clamping assembly is provided between the two inclined support arms above the first elastic pad. The auxiliary pipe clamping assembly includes a threaded sleeve vertically fixed to the top surface of the horizontal bottom beam, a lifting screw screwed to the threaded sleeve, and a lower clamping block hinged to the top of the lifting screw. The top surface of the lower clamping block is provided with a second elastic pad. The main pipe clamping assembly includes a support plate fixedly installed between the two inclined support arms, a movable plate disposed above the support plate via a buffer, and an adjusting screw threaded through the movable plate; the top end of the adjusting screw is provided with a knob, and the bottom end is rotatably connected to a V-shaped upper clamping block with its opening facing downward via a bearing; the inner wall of the V-shaped upper clamping block is provided with a third elastic pad; the main pipe clamping assembly also includes a guide mechanism that restricts the rotation of the V-shaped upper clamping block with the adjusting screw.

[0007] As a preferred embodiment of the present invention, which is a pipeline seismic support with excellent seismic resistance, at least two radially extending operating handles are fixedly provided on the upper part of the outer wall of the lifting screw.

[0008] As a preferred embodiment of the present invention, which is a pipeline seismic support with excellent seismic resistance, the buffer is a spring damper, which is detachably connected between the support plate and the movable plate by bolts.

[0009] As a preferred embodiment of the present invention, which is a pipeline seismic support with excellent seismic resistance, the guiding mechanism includes at least two guide rods symmetrically fixed to the top of the V-shaped upper clamping block, and the upper ends of the guide rods slide through the movable plate.

[0010] As a preferred embodiment of the present invention, which is a pipeline seismic support with excellent seismic resistance, the top surface of the fixed wing plate is fitted with an anti-slip pad.

[0011] As a preferred embodiment of the present invention, the inclined support arm is provided with multiple weight-reducing holes.

[0012] As a preferred embodiment of the present invention, the horizontal bottom beam, the inclined support arm, and the fixed wing plate are integrally bent from metal sheets or welded from structural steel.

[0013] As a preferred embodiment of the present invention, the first elastic pad, the second elastic pad, and the third elastic pad are all made of rubber or silicone.

[0014] The beneficial effects of this utility model are: 1. By using a V-shaped structure to decompose force and a dual elastic clamping system to dissipate energy, the destructive impact of seismic waves on the pipeline system is significantly reduced, effectively protecting life and property.

[0015] 2. Both the height of the lower clamping block and the pressure of the upper clamping block are adjustable. Combined with the inclusive design of the V-shaped opening, a single bracket can adapt to various models and pipe diameters within a certain range, reducing the types of spare parts and inventory costs in the project.

[0016] 3. All parts in contact with the pipeline are equipped with elastic pads, which avoids the problems of scratching and abrading the pipeline surface and electrochemical corrosion caused by traditional rigid supports. It is especially effective in protecting the anti-corrosion layer or soft pipelines.

[0017] 4. All clamping adjustments can be completed by manually rotating the operating handle and knob without the need for special tools, resulting in high construction efficiency and easy on-site debugging. The guiding mechanism ensures that no deflection occurs during the clamping process, and the detachable spring damper facilitates maintenance. The overall structure is robust and durable with a long service life. The weight-reducing hole design saves materials, and the universal design reduces the overall procurement and management costs, resulting in high economic benefits. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-3 A seismic-resistant pipe support with excellent seismic performance includes a support body 1, which is a V-shaped structure with the opening facing upward. The support body 1 is integrally formed by a horizontal bottom beam 2 and two inclined support arms 3 symmetrically fixed at both ends of the horizontal bottom beam 2. The top of the two inclined support arms 3 is provided with a horizontally outwardly extending fixed wing plate 4, and the fixed wing plate 4 is provided with mounting holes 5. The inner sidewalls of the two inclined support arms 3 are provided with a first elastic pad 6. An auxiliary pipe clamping assembly is provided in the middle of the top surface of the horizontal bottom beam 2, and a main pipe clamping assembly is provided between the two inclined support arms 3 above the first elastic pad 6. The auxiliary pipe clamping assembly includes a threaded sleeve 7 vertically fixed to the top surface of the horizontal bottom beam 2, a lifting screw 8 screwed to the threaded sleeve 7, and a lower clamping block 9 hinged to the top of the lifting screw 8. A second elastic pad 10 is provided on the top surface of the lower clamping block 9. The main pipe clamping assembly includes a support plate 11 fixedly installed between two inclined support arms 3, a movable plate 13 disposed above the support plate 11 via a buffer 12, and an adjusting screw 14 threaded through the movable plate 13; the top end of the adjusting screw 14 is provided with a knob 15, and the bottom end is rotatably connected to a V-shaped upper clamping block 16 with its opening facing downward via a bearing; the inner wall of the V-shaped upper clamping block 16 is provided with a third elastic pad 17; the main pipe clamping assembly also includes a guide mechanism that restricts the rotation of the V-shaped upper clamping block 16 with the adjusting screw 14.

[0024] In this embodiment: the support body 1 adopts an upward-facing V-shaped structure, which is integrally formed by a horizontal bottom beam 2 and an inclined support arm 3. It is fixed to the building foundation structure through fixed wing plates 4 and mounting holes 5 to form a stable support frame, providing a reliable installation foundation for the pipeline. After the pipeline is placed on the horizontal bottom beam 2 of the V-shaped support body 1, its two sides are initially laterally limited by the first elastic pads 6 on the inner side of the inclined support arm 3. The lifting screw 8 of the rotating auxiliary pipeline clamping assembly can drive the lower clamping block 9 to rise, so that the second elastic pad 10 at its top is pressed from the bottom and assists in supporting the pipeline. Then, the adjustment of the main pipeline clamping assembly is rotated. The screw 14 drives the V-shaped upper clamping block 16 to move downward and compress the spring damper, causing the third elastic pad 17 on its inner wall to press the pipe from above. At this time, the spring damper provides a continuous elastic preload, while the guide mechanism ensures that the vertical movement of the upper clamping block does not deflect. When an earthquake occurs, the multidimensional impact energy generated by the pipe is first buffered by the elastic pads of the upper and lower clamping blocks 9, and further absorbed and dissipated by the spring damper. The residual impact force is effectively decomposed into axial force through the inclined support arm 3 of the V-shaped structure, and finally safely transmitted to the main building structure connected by the fixed wing plate 4, thereby achieving excellent seismic protection effect.

[0025] As a technical optimization of this utility model, at least two radially extending operating handles 18 are fixedly provided on the upper part of the outer wall of the lifting screw 8.

[0026] In this embodiment, the operator can easily rotate the lifting screw 8 by adjusting the lifting screw 8 without the need for additional tools, which simplifies the height adjustment operation of the lower clamp 9, improves the adjustment efficiency, and enhances the convenience of using the bracket.

[0027] As a technical optimization of this utility model, the buffer 12 is a spring damper, which is detachably connected between the support plate 11 and the movable plate 13 by bolts 19.

[0028] In this embodiment: the spring damper has excellent energy absorption and dissipation capabilities, which can effectively improve the buffering and shock absorption effect and adapt to the multi-directional vibration of complex seismic waves; the detachable connection design facilitates the daily inspection, maintenance and replacement of the buffer 12, reduces the maintenance cost of the support, and extends the overall service life of the support.

[0029] As a technical optimization of this utility model, the guiding mechanism includes at least two guide rods 20 symmetrically fixed to the top of the V-shaped upper clamping block 16, and the upper end of the guide rod 20 passes through the movable plate 13 in a sliding fit.

[0030] In this embodiment: the guiding action of the guide rod 20 effectively restricts the rotation of the V-shaped upper clamping block 16 with the adjusting screw 14, ensuring that the V-shaped upper clamping block 16 always maintains the correct clamping direction. At the same time, it provides stable guidance for the V-shaped upper clamping block 16 when the pipeline vibrates, preventing it from deviating and improving the stability and reliability of pipeline clamping.

[0031] As a technical optimization of this utility model, the top surface of the fixed wing plate 4 is fitted with an anti-slip pad 21.

[0032] In this embodiment, the friction between the fixed wing plate 4 and the building foundation structure is increased to prevent the support from loosening under vibration and other working conditions, ensuring the firmness of the support installation and further improving the overall stability and seismic safety of the support.

[0033] As a technical optimization of this utility model, the inclined support arm 3 is provided with multiple weight reduction holes 22.

[0034] In this embodiment: while ensuring the structural strength of the inclined support arm 3, the overall weight of the support is reduced, the material cost is lowered, the transportation and installation of the support are facilitated, and the load on the building structure is reduced, thereby improving the overall safety performance of the building.

[0035] As a technical optimization of this utility model, the horizontal bottom beam 2, the inclined support arm 3 and the fixed wing plate 4 are integrally bent from metal sheets or welded from structural steel.

[0036] In this embodiment: integral bending and forming can ensure the integrity and structural strength of the connection of each component of the support body 1, reduce connection nodes, and reduce the risk of loosening; the steel welding can select appropriate steel according to actual needs, ensuring structural strength while improving manufacturing flexibility. Both manufacturing methods can ensure that the support body 1 has good load-bearing capacity and seismic performance.

[0037] As a technical optimization of this utility model, the first elastic pad 6, the second elastic pad 10 and the third elastic pad 17 are all made of rubber or silicone.

[0038] In this embodiment, the rubber and silicone materials have good elasticity, wear resistance and aging resistance, and can play a stable role in buffering and shock absorption for a long time, effectively protecting the outer surface of the pipe from wear. At the same time, they can adapt to different usage environments, extend the service life of the elastic pad, and ensure the durability of the overall shock resistance of the support.

[0039] Working principle and usage process of this utility model: First, the fixing wing plate 4 of the bracket is securely installed on the building's roof or side wall using fixing bolts. The pipe to be fixed is placed into the V-shaped opening of the bracket, temporarily resting on the horizontal bottom beam 2. After the pipe is naturally placed, its lower part is supported by the horizontal bottom beam 2, and its two sides are initially laterally limited by the first elastic pad 6 on the inner side of the inclined support arm 3. The lifting screw 8 is rotated to drive the lower clamping block 9 to rise until the second elastic pad 10 at its top is in close contact with the bottom of the pipe, providing a stable bottom support force for the pipe. The adjusting screw 14 of the main pipe clamping assembly is rotated to drive the upper V-shaped clamping block 16 to move downward, compressing the spring damper, so that the third elastic pad 17 presses the pipe from above. The continuous elastic force provided by the spring damper ensures stable clamping force and can adapt to the thermal expansion and contraction of the pipe. When an earthquake occurs, the pipe vibrates or shifts. The impact force is buffered by the upper and lower elastic pads, absorbed and dissipated by the spring damper, and the residual force is decomposed and transmitted to the main building through the V-shaped inclined support arm 3, thereby ensuring the safety of the pipeline system.
