Description

Technical Field

[0001] This utility model relates to the field of support and hanger technology, specifically to a nested variable spring hanger. Background Technology

[0002] Variable spring supports are devices used to support pipes and equipment. They are mainly used to absorb, reduce, or release the adhesion stress from pipes and equipment, ensuring normal operation of the overall pipeline or equipment. They can control pipe displacement within acceptable standard ranges, ensuring torque balance, and are one of the most widely used pipe fittings in many pipeline machinery and equipment requiring torque balance.

[0003] A search revealed a nested variable spring support bracket (publication number: CN219367014U) in the prior art. The document describes that "the base plate is connected to the top plate via a spring cylinder. The spring cylinder has holes, an indicator plate is installed inside the spring cylinder with both ends extending out of the holes, a load tube passes through the top plate and is threadedly connected to the indicator plate, and a first spring support mechanism and a second spring support mechanism are installed inside the spring cylinder located between the indicator plate and the base plate." In this support bracket, the outer, middle, and inner springs have the same spring stiffness and height. When the load plate applies force, all springs are compressed simultaneously, and the spring support force is balanced. While the support aims to balance pipe weight, reduce pipe stress, and extend pipe lifespan, it also incorporates nesting plates, a second base plate, an inner nesting plate, a first base plate, and spring guide tubes to separate the outer, middle, and inner springs. This increases the overall weight and material usage of the support, reducing its ease of transport and movement, and raising production costs. Furthermore, the holes on both sides of the spring cylinder for the indicator plates allow external debris to easily enter, interfering with the outer springs, reducing their compression effect, and consequently decreasing the overall support effectiveness of the support, increasing the likelihood of failure and damage. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, a nested variable spring hanger is provided to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a nested variable spring hanger is provided, comprising: a base plate, on the upper surface of which a cylinder and a mounting ring are fixedly connected respectively; guide rods are symmetrically connected to the upper surface of the mounting ring; limiting grooves are symmetrically opened at the upper end of the cylinder; main sliding grooves are symmetrically opened in the inner cavity of the cylinder; a cover plate is fixedly connected to the upper surface of the cylinder; an elastic element is fixedly connected to the bottom of the inner cavity of the cylinder; a pressure plate is slidably connected to the inner cavity of the cylinder through guide rods; main sliding plates are connected to the two sides of the pressure plate at positions corresponding to the main sliding grooves; an indicator plate is fixedly connected to the surface of the main sliding plate and slidably connected in the limiting groove; and a load tube is fixedly connected to the upper surface of the pressure plate, with a load plate fixedly connected to the upper end of the load tube.

[0006] Preferably, a positioning groove is formed on the upper surface of the base plate. The positioning groove has a circular structure and the dimensions of the positioning groove and the lower end face of the cylinder are compatible. At the same time, the cylinder has a cylindrical structure and the cover plate on the upper surface of the cylinder has a circular structure.

[0007] Preferably, two sets of mounting grooves are equally spaced on the upper surface of the base plate. Both sets of mounting grooves are circular ring structures and are concentrically distributed on the upper surface of the base plate. At the same time, two sets of positioning holes are symmetrically opened at the bottom of the inner cavity of the mounting grooves.

[0008] Preferably, there are two sets of mounting rings, the two sets of mounting rings and the corresponding two sets of mounting grooves are adapted to each other, and the lower surface of the mounting ring is connected to the positioning post relative to the positioning hole, the positioning post having a cylindrical structure.

[0009] Preferably, multiple sets of guide rods are fixedly connected around the upper surface of the mounting ring at equal intervals in the circumferential direction, and all sets of guide rods are cylindrical in shape, with the axial length of the guide rods being equal to the axial length of the inner cavity of the cylinder.

[0010] Preferably, the pressure plate has a circular structure, the size of the pressure plate and the inner cavity of the cylinder are adapted to each other, and the surface of the pressure plate is provided with guide holes corresponding to the position of the guide rod. The size of the guide holes and the guide rod are adapted to each other. At the same time, the inner cavity of the cylinder is connected to three sets of elastic elements through the guide rod. The diameter of the three sets of elastic elements decreases from the outside to the inside to form a concentric circle structure.

[0011] Preferably, the two sets of main sliding plates fixedly connected to both sides of the pressure plate are both elongated strip structures, and the dimensions of the main sliding plates and the main sliding grooves are matched.

At the same time, the indicator plate fixedly connected to the upper end of the main sliding block is square, and scale lines are opened on the surface of the main sliding block.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: through the cooperation of the base plate, guide rod, cylinder and pressure plate, three sets of elastic elements can be coaxially nested inside the cylinder, which helps to improve the load-bearing capacity and enhance the support effect of the hanger. Moreover, it can not only avoid the problem of misalignment and tilting of the three sets of elastic elements during compression, but also effectively reduce the overall weight and material consumption of the hanger, improve the convenience of transportation and movement, and help reduce production costs. At the same time, through the cooperation of the pressure plate, main slide plate and main slide groove, the opening of the limiting groove can be effectively blocked, so that external debris cannot fall into the elastic elements, ensuring that the elastic elements have normal compressive elasticity, and helping to reduce the probability of hanger failure and damage.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1 to 4As shown, this utility model provides a nested variable spring hanger, including: a base plate 1, a cylinder 3 and a mounting ring 2 are fixedly connected to the upper surface of the base plate 1 respectively, a guide rod 4 is symmetrically connected to the upper surface of the mounting ring 2, a limiting groove 13 is symmetrically opened at the upper end of the cylinder 3, and a main sliding groove 5 is symmetrically opened in the inner cavity of the cylinder 3, a cover plate 10 is fixedly connected to the upper surface of the cylinder 3, and an elastic element 6 is fixedly connected to the bottom of the inner cavity of the cylinder 3. At the same time, a pressure plate 8 is slidably connected to the inner cavity of the cylinder 3 through the guide rod 4, and a main sliding plate 7 is connected to the positions of the two sides of the pressure plate 8 relative to the main sliding groove 5. An indicator plate 9 is fixedly connected to the surface of the main sliding plate 7 and slidably connected in the limiting groove 13. A load tube 11 is fixedly connected to the upper surface of the pressure plate 8, and a load plate 12 is fixedly connected to the upper end of the load tube 11.

[0020] In this embodiment, the mounting ring 2 and the cylinder 3 are sequentially fixedly connected to the bottom upper surface through the mounting groove and positioning groove 14, respectively. Three sets of elastic elements 6 with different diameters are nested in the inner cavity of the cylinder 3, and the three sets of elastic elements 6 are separated and limited by the guide rod 4. After the guide hole 15 on the surface of the pressure plate 8 is aligned with the guide rod 4, it is moved downward, so that the pressure plate 8 can be smoothly slidably connected inside the cylinder 3. The lower surface of the pressure plate 8 can be fixedly connected to the three elastic elements 6. At the same time, the indicator plate 9 and the main slide plate 7 on both sides of the pressure plate 8 will be slidably connected in the limiting groove 13 and the main slide groove 5, respectively, and the main slide plate 7 will close the limiting groove 1. The opening at the lower end of the 3-section prevents external debris from falling under the pressure plate 8, thereby effectively reducing the probability of the elastic element 6 being disturbed by external debris and ensuring that the elastic element 6 can perform normal compression and reset, thus reducing the probability of the hanger malfunctioning or being damaged. The load tube 11 is fixedly connected to the upper surface of the pressure plate 8, and the upper end of the load tube 11 passes through the through hole in the middle of the cover plate 10 and is fixedly connected to the load plate 12. The cover plate 10 is fixedly connected to the upper surface of the cylinder 3, which enables convenient assembly of the hanger, reduces the overall weight for easy transportation and movement, reduces the amount of material used, and lowers production costs.

[0021] In a preferred embodiment, a positioning groove 14 is provided on the upper surface of the base plate 1. The positioning groove 14 has a circular structure and the dimensions of the positioning groove 14 and the lower end face of the cylinder 3 are compatible. At the same time, the cylinder 3 has a cylindrical structure and the cover plate 10 provided on the upper surface of the cylinder 3 has a circular structure.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The opening of the positioning groove 14 enables the cylinder 3 to be positioned on the surface of the base plate 1 conveniently and quickly, and also helps to enhance the fixed connection effect between the base plate 1 and the cylinder 3.

[0023] As a preferred embodiment, two sets of mounting grooves are equally spaced on the upper surface of the base plate 1. Both sets of mounting grooves are circular in structure and are concentrically distributed on the upper surface of the base plate 1. At the same time, two sets of positioning holes are symmetrically opened at the bottom of the inner cavity of the mounting groove.

[0024] In this embodiment, as Figure 1 and Figure 3 The opening of the mounting groove allows the mounting ring 2 to be easily and quickly fixedly connected to the surface of the base plate 1, and the setting of the positioning hole ensures that both sets of mounting rings 2 are embedded and fixed in the correct position, ensuring that the pressure plate 8 and guide rod 4 can be properly connected later.

[0025] As a preferred embodiment, there are two sets of mounting rings 2. The dimensions of the two sets of mounting rings 2 and the corresponding two sets of mounting grooves are adapted to each other. The lower surface of the mounting ring 2 is connected to the positioning pins relative to the positioning holes. The positioning pins are cylindrical in shape.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The dimensions of the positioning pin and the positioning hole are matched, which helps to enhance the positioning effect when the mounting ring 2 is inserted, and ensures that the guide rods 4 on the upper surface of the two sets of mounting rings 2 can be fixed in the sleeve at specific positions, thereby ensuring the smooth installation of the pressure plate 8.

[0027] In a preferred embodiment, multiple sets of guide rods 4 are fixedly connected around the upper surface of the mounting ring 2 at equal intervals in the circumferential direction, and all sets of guide rods 4 are cylindrical in shape. At the same time, the axial length of the guide rods 4 is equal to the axial length of the inner cavity of the cylinder 3.

[0028] In this embodiment, as Figure 1 and Figure 2 The position of the guide rod 4 restricts the position of the three sets of elastic elements 6 inside the cylinder 3, thereby enhancing the stability of the three sets of elastic elements 6 during compression and reset, preventing the elastic elements 6 from bending or tilting during compression, and ensuring the overall support effect of the hanger. At the same time, the hollow structure of the guide rod 4 can effectively reduce the overall weight of the hanger, reduce the amount of material used, and reduce production costs.

[0029] In a preferred embodiment, the pressure plate 8 has a circular structure, and the size of the pressure plate 8 is adapted to the inner cavity of the cylinder 3. The surface of the pressure plate 8 is provided with a guide hole 15 corresponding to the position of the guide rod 4, and the size of the guide hole 15 is adapted to the guide rod 4. At the same time, the inner cavity of the cylinder 3 is connected to three sets of elastic elements 6 through the guide rod 4. The diameter of the three sets of elastic elements 6 decreases from the outside to the inside to form a concentric circle structure.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The concentric nested structure of the three sets of elastic elements 6 can effectively enhance the overall load-bearing capacity of the hanger and improve its support effect on pipes and other components. The guide hole 15 can help enhance the stability of the pressure plate 8 when it moves and prevent the pressure plate 8 from tilting during the movement.

[0031] As a preferred embodiment, the two sets of main slide plates 7 fixedly connected to both sides of the pressure plate 8 are both elongated structures, and the dimensions of the main slide plates 7 and the main slide grooves 5 are matched. The length of the main slide grooves 5 is equal to the axial length of the cylinder 3, while the width of the main slide is greater than the width of the limiting groove 13. Meanwhile, the indicator plate 9 fixedly connected to the upper end of the main slide is square, and scale lines are opened on the surface of the main slide.

[0032] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The main slide plate 7 and the main slide groove 5 are matched in size, which helps to enhance the stability of the pressure plate 8 when it moves. The setting of the indicator plate 9 and the scale line can help improve the efficiency of workers in judging the compression distance of the hanger. At the same time, the size setting of the main slide plate 7 can help to close the opening of the limiting groove 13 located below the pressure plate 8, thereby reducing the accidental falling of external debris under the pressure plate 8, thereby reducing the interference effect of debris on the elastic element 6, and reducing the probability of the hanger malfunctioning or being damaged.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
