Description

Technical Field

[0001] This utility model relates to the field of support and hanger technology, specifically to a height-adjustable support and hanger. Background Technology

[0002] In modern industrial systems, such as petrochemicals, power (thermal power and nuclear power), metallurgy, municipal water supply and drainage, and shipbuilding, pipeline systems play a crucial role in transporting various fluid media (such as water, steam, oil, chemicals, and gases). These pipelines typically operate under complex and harsh conditions such as high temperature, high pressure, corrosion, and vibration for extended periods. To ensure the safe, stable, and long-term operation of the pipeline system, it is essential to provide reliable and reasonable support and fixation. Therefore, pipeline supports and hangers are the core components for achieving this function.

[0003] Traditional pipe supports can currently meet basic support needs, but in practical applications, especially in increasingly complex industrial environments, many technical shortcomings have gradually been exposed. For example, a large number of supports are mass-produced to fixed sizes. During installation, due to non-standard installation positions and the support requirements of long-distance pipelines, it is often necessary to perform tedious height adjustments on the pipeline on-site. Since traditional supports are manufactured to fixed sizes, such adjustments usually require the use of shims and other structures to assist in the adjustment to adapt to the installation height requirements of the pipeline. Although this method can partially solve on-site problems, the adjustment accuracy is poor and the operation is very inconvenient. Especially when working at heights, operators need to carry a large number of shims, and if necessary, holes need to be drilled in the shims to simultaneously pass through expansion bolts to ensure the installation stability of the shims. This operation method greatly reduces work efficiency and construction safety. Utility Model Content

[0004] This utility model proposes a height-adjustable support bracket to solve the problem that the length of traditional support brackets is often fixed after installation, making it difficult to flexibly adjust according to actual needs.

[0005] The technical solution of this utility model is as follows: A height-adjustable support bracket includes a connecting plate, the top of which is fixedly connected to a mounting ring, and further includes: a sliding cylinder, a sliding rod, a driving mechanism, and a limiting mechanism. Two sliding cylinders are provided, each fixedly connected to the top of the connecting plate. The sliding rod is slidably connected within each sliding cylinder. A mounting plate is fixedly connected to the top of each sliding rod, and the mounting plate has bolt holes. Each sliding cylinder is equipped with a driving mechanism for adjusting the position of the sliding rod within the cylinder, and each sliding cylinder is equipped with a limiting mechanism for limiting the adjusted sliding rod.

[0006] To drive the slide bar to move up and down within the slide cylinder, the driving mechanism includes: a rack, a support base, a one-way clutch gear, and a drive frame. The rack is mounted on one side wall of the slide bar. A strip-shaped groove is formed along the length of the slide cylinder, and the strip-shaped groove corresponds to the rack. The support base is fixedly connected to both sides of the strip-shaped groove. The one-way clutch gear is rotatably mounted within the support base and meshes with the rack. The shaft end of the one-way clutch gear penetrates the side wall of the support base and extends outward. The two mounting ends of the drive frame are respectively connected to the two shaft ends of the one-way clutch gear.

[0007] To limit the adjustment of the slide bar, the limiting mechanism includes: rack two, limiting head, elastic component, fixing plate, rotating shaft and elastic component. Rack two is installed on the other side wall of the slide bar. A strip groove two is opened on the slide cylinder. The strip groove two corresponds to the position of rack two. The limiting head is set on one side of the slide cylinder through the adjusting component. One end of the limiting head is engaged with rack two.

[0008] To support the rotation of the limiting clamp, the adjustment assembly includes: fixed plates fixedly installed on both sides of the second strip groove; the two ends of the rotating shaft respectively pass through the two fixed plates and are rotatably connected to the fixed plates; the limiting clamp is located between the two fixed plates and is fixedly connected to the rotating shaft; and the elastic component is disposed between the rotating shaft and the slide cylinder for limiting and clamping the limiting clamp on the second rack.

[0009] To support the limiting clamp head against the rack two, the elastic component includes: a support plate, a support frame, a support spring, and a limiting screw. The support plate is fixedly connected to the rotating shaft by two connecting rods. The support frame is mounted on both sides of the strip groove two and fixedly connected to the slide cylinder. The two ends of the support spring are fixedly connected to the support plate and the support frame, respectively. The limiting screw is threaded onto the support plate.

[0010] To increase the stability of the two slide bars, a stabilizing bar is provided between each slide bar. Each end of the stabilizing bar is provided with a dovetail slider. Each side of the two slide bars is provided with a dovetail groove, and the dovetail slider is slidably disposed in the dovetail groove. The length of the dovetail groove is greater than the length of the dovetail slider.

[0011] The slide bar has a threaded hole on its side wall, which communicates with the dovetail groove, and a locking screw is installed in the threaded hole.

[0012] The working principle and beneficial effects of this utility model are as follows:

[0013] In this invention, the orientation of the mounting plate is adjusted according to the usage of the pipeline. The entire assembly can be fixed to the mounting surface (ground, wall, or ceiling) at the installation location using expansion bolts and mounting holes on the mounting plate. Then, the mounting retaining ring is opened, and the pipeline is placed inside the mounting retaining ring. Based on the usage height of the pipeline, the relative position between the sliding cylinder and the sliding rod is adjusted using a drive mechanism, thereby adaptively adjusting the installation height of the pipeline. After finally determining the installation position of the pipeline, the mounting retaining ring is locked with bolts (a rubber pad can be placed between the mounting retaining ring and the pipeline to enhance the fixing effect and shock resistance). Compared with traditional supports and hangers, it is more adaptable and easier to operate. Furthermore, the two sets of sliding rods and sliding cylinder assemblies can be adjusted independently, allowing the two mounting plates to adapt to uneven installation surfaces, thus improving adaptability.

[0022] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] like Figures 1-5 As shown, this embodiment proposes a height-adjustable support bracket, including a connecting plate 1, with a mounting ring 2 fixedly connected to the top of the connecting plate 1, and further including: a sliding cylinder 3, a sliding rod 4, a driving mechanism, and a limiting mechanism. Two sliding cylinders 3 are provided, each fixedly connected to the top of the connecting plate 1. The sliding rod 4 is slidably connected within each sliding cylinder 3, and a mounting plate 5 is fixedly connected to the top of each sliding rod 4. The mounting plate 5 has bolt holes. Each sliding cylinder 3 is equipped with a driving mechanism for adjusting the position of the sliding rod 4 within the sliding cylinder 3. Each sliding cylinder 3 is also equipped with a limiting mechanism for limiting the adjusted sliding rod 4. The driving mechanism drives the sliding rod 4 to move within the sliding cylinder 3, thereby causing the mounting ring 2 on the support plate 14 to rise and fall. The limiting mechanism restricts the adjusted sliding rod 4 within the sliding cylinder 3, thus maintaining the stability of the support plate 14 and the mounting ring 2 after adjustment.

[0024] The driving mechanism includes: rack 6, support base 7, one-way clutch gear 9, and drive frame 8. Rack 6 is installed on one side wall of slide rod 4. A strip groove is formed on slide cylinder 3 along its length direction. The strip groove corresponds to the position of rack 6. Support base 7 is fixedly connected to both sides of strip groove. One-way clutch gear 9 is rotatably installed in support base 7. One-way clutch gear 9 meshes with rack 6. The shaft end of one-way clutch gear 9 passes through the side wall of support base 7 and extends outward. The two mounting ends of drive frame 8 are respectively connected to the two shaft ends of one-way clutch gear 9. When the operator presses drive frame 8 downward, it drives one-way clutch gear 9 to rotate. When one-way clutch gear 9 rotates, it drives rack 6 and slide rod 4 to rise in slide cylinder 3, thereby adjusting the height of mounting ring 2 on support plate 14.

[0025] The limiting mechanism includes: a second rack 10, a limiting head 11, an elastic component, a fixing plate 12, a rotating shaft 13, and an elastic component. The second rack 10 is installed on the other side wall of the slide rod 4. A strip-shaped groove is formed on the slide cylinder 3, and the strip-shaped groove corresponds to the position of the second rack 10. The limiting head 11 is set on one side of the slide cylinder 3 through an adjustment component. One end of the limiting head 11 engages with the second rack 10. The adjustment component includes a fixing plate 12 fixedly installed on both sides of the strip-shaped groove. The two ends of the rotating shaft 13 pass through the two fixing plates 12 respectively, and the rotating shaft 13 is rotatably connected to the fixing plates 12. The limiting head 11 is located between the two fixing plates 12 and is fixedly connected to the rotating shaft 13. The elastic component is set between the rotating shaft 13 and the slide cylinder 3 for limiting and pressing the limiting head 11 on the second rack 10. The elastic component includes: The system comprises a support plate 14, a support frame 16, a support spring 17, and a limiting screw 19. The support plate 14 is fixedly connected to the rotating shaft 13 via two connecting rods 15. The support frame 16 is mounted on both sides of the second strip groove and fixedly connected to the slide cylinder 3. The two ends of the support spring 17 are fixedly connected to the support plate 14 and the support frame 16, respectively. The limiting screw 19 is threaded onto the support plate 14. After the slide rod 4 moves up and down, the support plate 14 is supported by the support spring 17, thereby driving the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, the limiting clamp 11 abuts against the rack 10, and through the continuous support of the support spring 17, the slide rod 4 after height adjustment is limited within the slide cylinder 3. After the position of the pipeline is adjusted and fixed, the end of the limiting screw 19 can be pressed against the support frame 16 by rotating it, thereby ensuring the stability of the limiting clamp 11 and ensuring that the position of the pipeline is not affected by vibration after being supported.

[0026] A stabilizing rod 18 is provided between each of the sliding rods 4. A dovetail slider 20 is provided at both ends of the stabilizing rod 18. A dovetail groove is provided on the opposite side of each of the two sliding rods 4. The dovetail slider 20 is slidably disposed in the dovetail groove, and the length of the dovetail groove is greater than the length of the dovetail slider 20.

[0027] The slide rod 4 has a threaded hole on its side wall, which communicates with the dovetail groove. A locking screw 21 is installed in the threaded hole. The stability rod 18 enhances the connection stability between the two slide rods 4. At the same time, the cooperation between the dovetail slider 20 and the dovetail groove ensures that each slide rod 4 can be adjusted independently, ensuring its adaptability to the mounting surface. After the positions of the two slide rods 4 are determined and fixed, the locking screw 21 can lock the stability rod 18 and the slide rod 4 to prevent them from sliding again during use, thereby improving the stability of the entire support during use.

[0028] Working principle: When the height of the mounting ring 2 needs to be adjusted, the operator presses down on the drive frame 8 to drive the one-way clutch gear 9 to rotate. When the one-way clutch gear 9 rotates, it drives the rack 6 and the slide rod 4 to rise in the slide cylinder 3, thereby adjusting the height of the mounting ring 2 on the support plate 14. After the slide rod 4 moves up and down, the support plate 14 is supported by the support spring 17, which drives the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, it drives the limiting head 11 to abut against the rack 10. With the continuous support of the support spring 17, the slide rod 4 after the height adjustment is limited in the slide cylinder 3, thereby completing the upward adjustment of the mounting ring 2.

[0029] When the installation ring 2 needs to be adjusted downwards, the operator presses the support plate 14 to compress the support spring 17, thereby driving the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, it drives the limit clamp head 11 away from the rack 10, thereby releasing the limit on the slide rod 4. At this time, the installation ring 2 drives the slide cylinder 3 to descend on the slide rod 4 due to its own weight. After descending to the set height, the operator releases the support plate 14, so that the support spring 17 supports the support plate 14 again. After the height is adjusted, the pipeline can be installed.

[0030] Additionally, please refer to [the relevant information]. Figure 6 The one-way clutch gear 9 is a common limiting technology on the market. This type of gear has an internal ratchet structure, allowing the gear to rotate only in one direction and preventing rotation in the other. It is a well-known product that can be directly purchased by those skilled in the art. Its main working principle is as follows: the gear is hollow inside, with one-way teeth 22 arranged circumferentially on its inner wall. A turntable 23 is located in the middle of the gear, and clutch teeth 24 are hinged to the turntable 23. A spring 25 is located between the clutch teeth 24 and the turntable 23. When the gear rotates in the direction of the clutch teeth 24, the spring 25 is compressed, thus engaging the one-way teeth 24. At the top of the rotary table 22, the clutch tooth 24 does not mesh with the one-way tooth 22, allowing the gear to rotate in one direction. When the gear rotates in the opposite direction, the spring 25 will abut against the clutch tooth 24, causing the clutch tooth 24 to mesh with the one-way tooth 22, thereby limiting the gear and preventing it from rotating in the other direction. This application only uses it without changing its structure. For details, please refer to the "Electric Assist Bicycle Motor Gear Clutch" in the products of Taizhou Haipeng Machinery Co., Ltd. It should be noted that the company and links provided in this application are only for a more intuitive explanation of the one-way clutch gear 9.

[0031] In addition, when the support needs to hoist the pipe, the top plate is installed on the roof where the pipe needs to be hoisted. When it is necessary to support the pipe on the ground, the support is flipped over and the top plate is installed on the ground, thus achieving both pipe hoisting and pipe support.

[0032] In addition, to provide bidirectional support for the slide bar 4, a set of rack 2 10 and a limiting mechanism can be set on both sides of the slide bar 4. It should be noted that the gears on the rack 2 10 on both sides cannot face the same direction. One needs to face up and the other down. The corresponding limiting head 11 should also face up and the other down. When the limiting head 11 needs to be moved away from the rack 2 10, the operator can press the two support plates 14 with one hand at the same time, so that the two limiting heads 11 are moved away from the two rack 2 10 respectively.

[0033] In addition, the diameter of the installation ring 2 needs to be customized according to the specifications of the pipe. Generally, the specifications of pipes installed in the same system in a building are mostly the same. Therefore, it is only necessary to customize and mass-produce according to the specifications of the pipe that needs to be supported. Moreover, the rubber ring inside the installation ring 2 can be heated to improve the support and shock absorption of the pipe.

[0034] The orientation described in this embodiment is based on the top surface as the installation surface (i.e., the orientation of the suspended pipe). The orientation used in the description is a relative orientation, not an absolute orientation. In actual use, the installation position of the mounting plate 5 needs to be determined according to its usage to determine whether it is used as a hanger or a support. In addition, the materials of this product are all high-strength materials to ensure reliability. At the same time, all related components are treated with anti-corrosion to avoid long-term external exposure and rust that would affect disassembly and assembly.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
