Description

Technical Field

[0001] This utility model relates to the technical field of spring supports and hangers, and in particular to a constant force spring support and hanger that is installed securely. Background Technology

[0002] Constant force spring supports are mechanical devices designed based on the principle of torque balance. They are mainly used to provide constant support force when pipelines or equipment are displaced due to factors such as temperature changes and medium flow, thereby avoiding the generation of additional stress and ensuring the safe operation of the pipeline system.

[0003] A constant force spring support for easy installation is disclosed on the Chinese Patent Network (publication number: CN216407955U). It includes a fixed plate and a support shell. The fixed plate has a groove inside, and a rotating rod is rotatably connected inside the groove. One end of the rotating rod extends to the outside of the fixed plate. Two threaded sleeves are connected to both ends of the rotating rod, and sliders are threaded onto the two threaded sleeves. The sliders are slidably connected to the groove. An insert plate is provided on one side of the slider. A fixed block is connected to the top of the support shell. The lower surface of the fixed plate has a fixing groove that mates with the fixing block. Slots that mate with the insert plate are provided on both sides of the fixing block. This utility model, through the coordinated use of the fixed plate, support shell, groove, rotating rod, threaded sleeve, slider, insert plate, fixing block, fixing groove, and slots, achieves the effect of facilitating the installation of the support, improving work efficiency, and reducing swaying during pipe hoisting, thus reducing safety hazards.

[0004] The solution also has the following problems: When using this constant force spring support, the upper and lower clamps, connecting bolts, and threaded holes are used in combination to fix the upper and lower clamps to clamp and fix the pipe. However, since the internal curvature of the upper and lower clamps is the same, it is necessary to replace the appropriate clamps for pipes of different sizes. This results in low practicality and the inability to be adjusted to suit different pipe sizes, thus presenting certain drawbacks.

[0005] Therefore, in order to solve the above problems, this utility model provides a stable constant force spring support bracket. Utility Model Content

[0006] The purpose of this invention is to provide a stable constant force spring support to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a stable constant force spring support bracket, comprising a fixed plate, a mounting block at the bottom of the fixed plate, a support bracket shell at the bottom of the mounting block, three first dampers equally spaced on the top inner side of the support bracket shell, a connecting frame at the bottom of the first dampers, a connecting plate at the bottom of the connecting frame, guide rods symmetrically mounted at both ends of the bottom of the connecting plate, a horizontal plate mounted at the bottom of the guide rods and below the support bracket shell, a fixed seat at the bottom of the horizontal plate, a fixed frame at the bottom of the fixed seat, four sliding rods arranged in a circular array between the inner two sides of the fixed frame, a slider mounted on the outer ring surface of the sliding rod, a support column mounted on the outside of the slider, a fixed arc plate mounted at one end of the support column, four return springs mounted on the inner wall of the fixed arc plate, and a limit clamp plate mounted on the end of the return springs away from the fixed arc plate.

[0008] Preferably, a groove is provided on the inner bottom of the fixing plate, and a bidirectional threaded rod is installed between the inner walls of the groove. A handle is installed on one outer end of the fixing plate, and its shaft passes through the interior of the fixing plate and is connected to one end of the bidirectional threaded rod. Movable blocks are symmetrically installed on both ends of the outer ring surface of the bidirectional threaded rod. A limit block is installed on the bottom of each movable block. Limit holes are provided on both outer ends of the mounting block, and one outer end of the limit block can slide into the interior of the limit hole.

[0009] Preferably, positioning rods are symmetrically installed at the bottom of the fixing plate and on both sides of the slide groove, and positioning grooves are provided at the top two ends of the mounting block. The outer ring size of the positioning rod is adapted to the inner sidewall size of the positioning groove.

[0010] Preferably, a fixing lug is installed on the inner top of the support and hanger housing and on both sides of the first damper. A second damper is rotatably connected to one end of the outer bottom of the fixing lug. The end of the second damper away from the fixing lug is rotatably connected to the outer end of the connecting frame. The outer ring surface of the guide rod is slidably connected to the inside of the support and hanger housing.

[0011] Preferably, the outer ring surface of the slide rod is slidably connected to the inside of the slider, a rotating ring is rotatably connected to the outside of the fixing frame, and four arc-shaped grooves are formed in a ring array on the outside of the rotating ring. The support columns are all located inside the corresponding arc-shaped grooves, and anti-slip pads are installed on the inner sidewall of the limiting clamp.

[0012] Preferably, a first connecting ear is installed on one outer end of the fixing frame, a second connecting ear is installed on one outer end of the swivel, an electric telescopic rod is installed between the first connecting ear and the second connecting ear, and both ends of the electric telescopic rod are rotatably connected to the first connecting ear and the second connecting ear.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] This type of stable constant force spring support works by rotating a handle to rotate a bidirectional threaded rod, causing two movable blocks on it to move towards each other along a sliding groove. The movable blocks drive a limiting block to move until the limiting block inserts into a limiting hole on the mounting block, thus fixing the mounting block to a fixed plate. When the pipeline is subjected to a large impact or vibration, the connecting plate distributes the force to three first dampers. The first dampers absorb and disperse some of the vibration energy through their own damping characteristics, thus playing a buffering role. When the connecting frame moves under force, the second damper further absorbs and disperses energy through its own damping characteristics, enhancing the buffering effect of the pipeline. When the rotating ring is rotated, the support column is located in the arc groove of the rotating ring, and the side wall of the arc groove pushes the support column to move. The support column drives the slider to slide on the sliding rod, thereby moving the fixed arc plate and the limiting clamping plate, realizing the clamping and fixing of pipelines of different sizes. It is convenient to operate and has better practicality. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1 - Figure 6 The present invention will be described in further detail below.

[0023] A stable constant force spring support bracket, as shown in the reference. Figure 1 - Figure 6 The system includes a fixed plate 1, a mounting block 2 at the bottom of the fixed plate 1, a support shell 3 at the bottom of the mounting block 2, three first dampers 4 evenly spaced on the top inner side of the support shell 3, a connecting frame 5 at the bottom of the first dampers 4, a connecting plate 6 at the bottom of the connecting frame 5, guide rods 7 symmetrically mounted at both ends of the bottom of the connecting plate 6, a horizontal plate 8 at the bottom of the guide rods 7 and below the support shell 3, a fixed seat 9 at the bottom of the horizontal plate 8, a fixed frame 10 at the bottom of the fixed seat 9, four sliding rods 11 arranged in a ring array between the two sides of the inner side of the fixed frame 10, a slider 12 mounted on the outer ring surface of the slider 11, a support column 13 mounted on the outside of the slider 12, a fixed arc plate 14 mounted on one end of the support column 13, four return springs 15 mounted on the inner side wall of the fixed arc plate 14, and a limit clamp 16 mounted on the end of the return springs 15 away from the fixed arc plate 14.

[0024] Reference Figure 1 - Figure 3A groove 101 is provided on the inner bottom of the fixed plate 1. A bidirectional threaded rod 17 is installed between the inner walls of the groove 101. A handle 18 is installed on one outer end of the fixed plate 1, and its shaft passes through the interior of the fixed plate 1 and connects to one end of the bidirectional threaded rod 17. Movable blocks 19 are symmetrically installed on both ends of the outer ring surface of the bidirectional threaded rod 17. Limiting blocks 20 are installed on the bottom of each movable block 19. Limiting holes 201 are provided on both outer ends of the mounting block 2. The outer end of the limiting block 20 can slide into the interior of the limiting hole 201. By rotating the handle 18, the bidirectional threaded rod 17 is driven to rotate. Since the threads at both ends of the bidirectional threaded rod 17 are in opposite directions, the two movable blocks 19 on it move towards each other along the groove 101. Block 19 moves the limiting block 20 until the limiting block 20 is inserted into the limiting hole 201 on the mounting block 2, thereby fixing the mounting block 2 onto the fixing plate 1. Positioning rods 21 are symmetrically installed on the bottom of the fixing plate 1 and on both sides of the slide groove 101. Positioning grooves 202 are provided at the top two ends of the mounting block 2. The outer ring size of the positioning rod 21 is adapted to the inner side wall size of the positioning groove 202. When fixing the mounting block 2, the positioning rod 21 and the positioning groove 202 play a positioning and guiding role. By aligning the positioning groove 202 on the mounting block 2 with the positioning rod 21 at the bottom of the fixing plate 1 and inserting it, the mounting block 2 can be quickly and accurately placed at the predetermined position at the bottom of the fixing plate 1, which is convenient for subsequent fixing through the limiting block 20 and the limiting hole 201.

[0025] Reference Figure 3 - Figure 4 Fixed ears 22 are installed on the top inner side of the support shell 3 and on both sides of the first damper 4. A second damper 23 is rotatably connected to one end of the bottom outer side of the fixed ear 22. The end of the second damper 23 away from the fixed ear 22 is rotatably connected to the outer end of the connecting frame 5. The outer ring surface of the guide rod 7 is slidably connected to the inside of the support shell 3. When the pipeline is subjected to a large impact force or vibration, the connecting plate 6 distributes the force to the three first dampers 4. The first dampers 4 absorb and disperse part of the vibration energy through their own damping characteristics to play a buffering role. One end of the second damper 23 is fixed to the support shell 3 through the fixed ear 22, and the other end is connected to the connecting frame 5. When the connecting frame 5 is moved by force, the second damper 23 further absorbs and disperses energy through its own damping characteristics to enhance the buffering effect of the pipeline. The guide rod 7 slides in the support shell 3 to ensure that the connecting frame 5 and the connecting plate 6 move stably in the vertical direction and prevent them from deviating.

[0026] Reference Figure 5 - Figure 6A first connecting ear 25 is installed on one outer end of the fixed frame 10, and a second connecting ear 26 is installed on one outer end of the rotating ring 24. An electric telescopic rod 27 is installed between the first connecting ear 25 and the second connecting ear 26. Both ends of the electric telescopic rod 27 are rotatably connected to the first connecting ear 25 and the second connecting ear 26. When it is necessary to adjust the position of the rotating ring 24 to change the position of the fixed arc plate 14 and the limiting clamp 16, the electric telescopic rod 27 is controlled to extend and retract. One end of the electric telescopic rod 27 is fixed to the fixed frame 10 through the first connecting ear 25, and the other end is connected to the rotating ring 24 through the second connecting ear 26. When the electric telescopic rod 27 extends and retracts, it will drive the rotating ring 24 to rotate. The outer ring surface of the slide rod 11 and the inside of the slider 12 are... The fixed frame 10 is rotatably connected to a rotating ring 24. The outer side of the rotating ring 24 has four arc-shaped grooves 2401 arranged in a ring array. The support columns 13 are all located inside the corresponding arc-shaped grooves 2401. Anti-slip pads are installed on the inner sidewalls of the limiting clamps 16. When the rotating ring 24 is rotated, the sidewalls of the arc-shaped grooves 2401 push the support columns 13 to move because the support columns 13 are located inside the arc-shaped grooves 2401 of the rotating ring 24. The support columns 13 drive the slider 12 to slide on the slide rod 11, thereby moving the fixed arc plate 14 and the limiting clamps 16 to achieve clamping and fixing of pipes of different sizes. The anti-slip pads can increase the friction between the limiting clamps 16 and the pipe, prevent the pipe from sliding and improve the stability of the fixation.

[0027] The implementation principle of a stable constant force spring support in this embodiment of the present invention is as follows: When using the device, the positioning rod 21 and the positioning groove 202 play a positioning and guiding role when fixing the mounting block 2. By aligning the positioning groove 202 on the mounting block 2 with the positioning rod 21 at the bottom of the fixing plate 1, the mounting block 2 can be quickly and accurately placed at the predetermined position at the bottom of the fixing plate 1, which facilitates subsequent fixing through the limiting block 20 and the limiting hole 201. By rotating the handle 18, the bidirectional threaded rod 17 is driven to rotate. Since the threads at both ends of the bidirectional threaded rod 17 are opposite, the two movable blocks 19 on it slide along the groove 10. 1. Moving towards each other, the movable block 19 drives the limiting block 20 to move until the limiting block 20 is inserted into the limiting hole 201 on the mounting block 2, thereby fixing the mounting block 2 to the fixing plate 1. This facilitates easy assembly and disassembly. When the pipeline is subjected to a large impact or vibration, the connecting plate 6 distributes the force to the three first dampers 4. The first dampers 4 absorb and disperse part of the vibration energy through their own damping characteristics, thus playing a buffering role. One end of the second damper 23 is fixed to the support shell 3 through the fixing ear 22, and the other end is connected to the connecting frame 5. When the connecting frame 5 is subjected to force and moves, the second damper 23 further absorbs and disperses energy through its own damping characteristics. To enhance the buffering effect of the pipeline, the guide rod 7 slides within the support housing 3 to ensure the stable vertical movement of the connecting frame 5 and the connecting plate 6, preventing them from shifting. When it is necessary to adjust the position of the rotating ring 24 to change the position of the fixed arc plate 14 and the limiting clamp 16, the electric telescopic rod 27 is controlled to extend and retract. One end of the electric telescopic rod 27 is fixed to the fixed frame 10 through the first connecting ear 25, and the other end is connected to the rotating ring 24 through the second connecting ear 26. When the electric telescopic rod 27 extends and retracts, it will drive the rotating ring 24 to rotate. When the rotating ring 24 rotates, since the support column 13 is located in the arc groove 2401 of the rotating ring 24, the arc groove 2401... The side wall of 401 will push the support column 13 to move, and the support column 13 will drive the slider 12 to slide on the slide rod 11, thereby moving the fixed arc plate 14, the return spring 15 and the limiting clamp 16 to achieve clamping and fixing of pipes of different sizes. The anti-slip pad can increase the friction between the limiting clamp 16 and the pipe, prevent the pipe from sliding and improve the stability of the fixation. It is convenient to operate and has better practicality. The threads on both sides of the bidirectional threaded rod 17 are opened in opposite directions, with equal pitch and a thread opening angle of 20 degrees. The thread self-locking condition needs to meet the following formula calculation: self-locking condition = friction coefficient * tan (helix angle) ≥ 1.
