Description
An anti-seismic support bracket capable of adjusting the length of pipe protection Technical Field
[0001] This utility model relates to the field of support technology, and in particular to an anti-seismic support bracket capable of adjusting the length of pipe protection. Background Technology
[0002] With the continuous development of society and the continuous progress of science and technology, pipeline protection technology is also constantly improving. During an earthquake, pipelines are easily shaken and ruptured, causing leaks and losses. During pipeline installation, seismic supports are usually added to reduce the impact of earthquakes on pipelines. Seismic supports are generally installed in the suspended position between adjacent fixed ends of the pipeline to prevent the pipeline from shaking in the middle during vibration and to protect the pipeline joints.
[0003] The seismic bracing currently in use has short pipe clamps with fixed dimensions, making it impossible to adjust them according to the length of the pipe. This results in a short protection length for the pipe, making the pipe prone to breakage due to uneven stress during vibrations, which is detrimental to the use of seismic bracing. Summary of the Invention
[0004] The purpose of this utility model is to address the following shortcomings in the prior art by proposing an anti-seismic support bracket capable of adjusting the protection length of pipes.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An adjustable seismic support bracket for pipe protection includes two pipe clamps connected by a connecting strip. Each pipe clamp has an arc-shaped placement opening and a concave groove for the reciprocating movement of the connecting strip. A reciprocating screw is rotatably connected to each concave groove, and the connecting strip and the two reciprocating screws are threadedly connected. The connecting strip has multiple equally spaced threaded grooves, two of which are threadedly connected to mounting rods. An arc-shaped support plate is fixedly connected to the upper end of each mounting rod. A limiting component is provided above the pipe clamps. The limiting component includes a concave frame with a vertical rod threadedly connected to it. An arc-shaped pressure plate is provided at the lower end of the vertical rod, and a rubber pad is fixedly connected to the surface of the arc-shaped pressure plate.
[0007] Preferably, each of the pipe clamps has a sliding groove on both its front and rear surfaces, and a movable strip is slidably connected in each sliding groove. A spring is fixedly connected to the lower surface of the movable strip, and the spring is fixedly connected to the lower inner wall of the sliding groove.
[0008] Preferably, each of the moving bars is fixedly connected with multiple insert rods, the bottom of the concave frame is fixedly connected with two hollow cylinders, each hollow cylinder is inserted with a limiting rod, each insert rod is provided with a through hole, and each of the pipe clamps is provided with multiple circular grooves on both sides.
[0009] Preferably, each of the concave grooves has a rectangular groove on its lower inner wall, and a slider is slidably connected in the rectangular groove. The slider and the lower surface of the connecting strip are fixedly connected.
[0010] Preferably, a gear is fixedly connected to each of the reciprocating lead screws, and a fixing rod is fixedly connected to the lower surface of each of the moving bars, the fixing rod being used to limit the rotation of the gear.
[0011] Preferably, each of the arc-shaped pressure plates has a connecting groove on its surface for connecting the vertical rod, the arc-shaped pressure plate is bolted to the vertical rod, and the vertical rod has a fixing groove for connecting the bolt.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In use, rotating the two reciprocating screws sequentially adjusts the distance between the two pipe clamps. Then, the pipe clamps are fitted onto the outer side, with the lower surface of the pipe conforming to the surfaces of the various arc-shaped support plates. Multiple concave brackets are installed above the two pipe clamps, and each hollow cylinder is fitted onto the outer side of its corresponding insert. Pressing down on the concave brackets causes the spring's deformation to reach its maximum, at which point the rubber pad on the surface of the arc-shaped pressure plate conforms to the upper surface of the pipe. Then, one end of each limiting rod passes through the hollow cylinder and the through hole, connecting to the corresponding circular groove thread. A connecting strip connects the two pipe clamps together. During vibration, the two adjacent pipe clamps generate a consistent frequency, preventing pipe breakage due to uneven stress. The distance between the two pipe clamps can be adjusted according to the pipe length, and the protection length for the pipe can be adjusted according to actual conditions. This improves the seismic resistance and support of suspended pipes, facilitating the use of seismic supports and hangers. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Referring to Figures 1-5, an anti-seismic support bracket capable of adjusting the pipe protection length includes two pipe clamps 1. Two U-shaped brackets with mounting holes can be fixedly fitted onto the outer sides of the two pipe clamps 1 respectively to facilitate the installation of the pipe clamps 1. The two pipe clamps 1 are connected by a connecting strip 2. Each pipe clamp 1 has an arc-shaped placement opening, and each pipe clamp 1 has a concave groove for the reciprocating movement of the connecting strip 2. A reciprocating screw 15 is rotatably connected in each concave groove. The connecting strip 2 is threadedly connected to the two reciprocating screws 15. The connecting strip 2 has multiple openings. There are equidistant threaded grooves 17, two of which are internally threaded to a mounting rod 18. Each mounting rod 18 is fixedly connected to an arc-shaped support plate 7 at its upper end. A limit assembly is provided above the pipe clamp 1. The limit assembly includes a concave frame 10, on which a vertical rod 9 is threaded. An arc-shaped pressure plate 21 is provided at the lower end of the vertical rod 9. A rubber pad is fixedly connected to the surface of the arc-shaped pressure plate 21. Only one concave frame 10 is shown. Multiple concave frames 10, vertical rods 9, bolts 8, and arc-shaped pressure plates 21 can be installed according to actual needs.
[0022] Each pipe clamp 1 has a groove 13 on both its front and rear surfaces. A movable strip 3 is slidably connected within each groove 13. A spring 4 is fixedly connected to the lower surface of the movable strip 3, and the spring 4 is fixedly connected to the lower inner wall of the groove 13. Multiple insert rods 6 are fixedly connected to each movable strip 3. Two hollow cylinders 12 are fixedly connected to the bottom of the concave frame 10. A limiting rod 11 is inserted into each hollow cylinder 12. A through hole 19 is opened on each insert rod 6. Multiple circular grooves 14 are opened on both sides of each pipe clamp 1. The concave frame 10 is installed above the two pipe clamps 1, and each hollow cylinder 12 is fitted onto the corresponding insert rod. On the outside of 6, the lower end face of each hollow cylinder 12 is in contact with the upper surface of the corresponding moving strip 3. At this time, the connecting hole on the hollow cylinder 12 coincides with the through hole 19. Then, continue to press down on the concave frame 10. The moving strip 3 moves vertically down along the slide groove 13. The spring 4 deforms. When the deformation of the spring 4 reaches its maximum, the rubber pad on the surface of the arc-shaped pressure plate 21 is in contact with the upper surface of the pipe. At this time, each through hole 19 is set face to face with the corresponding circular groove 14. Then, one end of each limiting rod 11 passes through the connecting hole and the through hole 19 and is threaded to the corresponding circular groove 14, which can effectively prevent the concave frame 10 from separating from the pipe clamp 1.
[0023] Each concave groove has a rectangular groove 16 on its lower inner wall. A slider is slidably connected in the rectangular groove 16. The slider and the lower surface of the connecting strip 2 are fixedly connected. The cooperation between the slider and the rectangular groove 16 can limit the movement trajectory of the connecting strip 2 and effectively prevent the connecting strip 2 from completely detaching from the pipe clamp 1. A gear 5 is fixedly connected to each reciprocating screw 15. A fixing rod 20 is fixedly connected to the lower surface of each moving strip 3. The fixing rod 20 is used to limit the rotation of the gear 5. In the initial state, the fixing rod 20 is completely above the gear 5. The limiting rod 11 passes through the connecting hole and the through hole 19 and is threadedly connected to the corresponding circular groove 14. That is, when the deformation of the spring 4 reaches its maximum, one end of the fixing rod 20 will be stuck between the teeth of the gear 5 and fit against the surface of the teeth, which can effectively prevent the gear 5 and the reciprocating screw 15 from rotating at will.
[0024] Each arc-shaped pressure plate 21 has a connecting groove on its surface for connecting the vertical rod 9. The arc-shaped pressure plate 21 is connected to the vertical rod 9 by bolts 8. The vertical rod 9 has a fixing groove for connecting the bolts 8. One end of the vertical rod 9 is inserted into the connecting groove, and then one end of the bolt 8 is inserted into the connecting groove and threaded into the fixing groove. This allows the arc-shaped pressure plate 21 to be firmly connected to the vertical rod 9, making it convenient to replace arc-shaped pressure plates 21 of different sizes according to actual needs.
[0025] In use, the two reciprocating screws 15 are rotated sequentially, and the connecting strip 2 slides in the concave grooves of the two pipe clamps 1, thereby adjusting the distance between the two pipe clamps 1. Depending on the actual pipe specifications and the number of exposed threaded grooves 17, multiple appropriately sized arc-shaped support plates 7 are installed on the connecting strip 2, meaning each vertical rod 9 is threadedly connected to its corresponding threaded groove 17. Then, the pipe clamps 1 are fitted onto the outside, with the lower surface of the pipe (not shown) fitting against the arc-shaped placement openings of the two pipe clamps 1 and the surfaces of each arc-shaped support plate 7. Next, multiple concave frames 10 are installed above the two pipe clamps 1, with each hollow cylinder 12 fitted onto the outside of its corresponding insert rod 6. The lower end face of each hollow cylinder 12 fits against the upper surface of its corresponding moving strip 3. At this point, the connecting hole on the hollow cylinder 12 coincides with the through hole 19. Then, the concave frames 10 are pressed downwards, and the moving strip 3 slides along the groove 1. 3. When the spring 4 moves vertically downward, it deforms. When the deformation of the spring 4 reaches its maximum, the rubber pad on the surface of the arc-shaped pressure plate 21 fits against the upper surface of the pipe. At this time, each through hole 19 is set face-to-face with the corresponding circular groove 14. Then, one end of each limiting rod 11 passes through the connecting hole and the through hole 19 and is threaded to the corresponding circular groove 14, which can effectively prevent the concave frame 10 from separating from the pipe clamp 1. Under the combined action of the arc-shaped support plate 7 and the arc-shaped pressure plate 21, the pipe can be clamped and fixed. The connecting strip 2 connects the two pipe clamps 1 together. When vibrating, the two adjacent pipe clamps 1 can generate a consistent frequency, thereby avoiding pipe breakage due to uneven force. The distance between the two pipe clamps 1 can be adjusted according to the length of the pipe. The protection length of the pipe can be adjusted according to the actual situation, which can improve the seismic resistance and support of the suspended pipe and is beneficial to the use of seismic supports and hangers.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
