Description

Technical Field

[0001] The present invention relates to a support device which can be used in the fields of civil engineering, building structure, machinery, transportation, aviation, aerospace, transmission pipelines, bridges, etc. Background Art

[0002] Support devices are widely used in civil engineering, building structures, machinery, transportation and other fields, including mobile anti-separation supports for building structures and machinery, supports for highway and railway bridges, active and passive control supports for aviation and aerospace equipment, and passive control supports for pipelines and lines.

[0003] Currently commonly used mobile supports include:

[0004] 1. A double-sided limited friction sliding bearing (Patent No.: ZL 01 1 15216.8), comprising a circular upper friction sliding member (one flat surface, one flat surface with protruding edges and a flat center) and a lower friction sliding member (one flat surface, one flat surface with protruding edges and a flat center). A middle sliding member is located between the upper and lower friction sliding members, and the middle sliding member is a flat plate. This bearing is a sliding friction isolation bearing with advantages such as large horizontal sliding and limited horizontal displacement. Its main disadvantages include: 1) the inability to control the vertical displacement of the upper and lower sliding plates of the bearing under external forces perpendicular to the translation; 2) the inability to automatically return to its original position after horizontal displacement; and 3) high requirements for the flatness of the mounting surface.

[0005] 2. Straight-sliding friction sliding bearing (patent number: ZL 01 2 12976.3), composed of an upper sliding plate and a lower sliding plate. The upper and lower sliding plates have a base membrane layer on one side of the steel plate substrate, and the base membrane layer is covered with a composite membrane layer, and the composite membrane layers of the upper and lower sliding plates are butt-jointed. This bearing is a sliding friction isolation bearing with the advantages of large horizontal sliding volume, large bearing capacity, and no edge effect of the upper and lower sliding plates under long-term loads; the main disadvantages include: 1) under the action of external forces perpendicular to the translation, the vertical displacement of the upper and lower sliding plates of the bearing cannot be controlled; 2) after horizontal displacement occurs, it cannot automatically return to its original position; 3) high requirements for the flatness of the installation surface.

[0006] 3. A vibration-controlled friction sliding bearing (patent number: ZL 01 1 06775.6), comprising an upper friction sliding plate and a lower friction sliding plate, connected between which are a control sliding block, a vibration-controlled connecting member and an intermediate sliding plate. One end of the control sliding block is connected to the lower friction sliding plate, and the other end is connected to a friction sliding support member. One end of the vibration-controlled connecting member is connected to the upper friction sliding plate, and the other end is connected to the intermediate sliding plate as a whole. This bearing is a sliding friction isolation bearing, which has the advantage of being able to control the horizontal sliding amount and vertical displacement between the upper friction sliding plate and the lower friction sliding plate, thereby improving the stability of horizontal sliding; the main disadvantages include: 1) the intermediate friction sliding support member and the intermediate sliding plate restrict each other, so that the displacement that can be provided is limited, which affects the use; 2) due to the insufficient displacement, it is not conducive to the setting of a horizontal reset component; 3) the components of the bearing are all rigidly connected, and when rubber pads are used on the upper and lower surfaces of the upper friction sliding plate and the lower friction sliding plate respectively, the service life is affected.

[0007] 4. A rolling friction resettable bearing, consisting of an upper rolling friction support plate, a lower rolling friction support plate, and a spherical body; the upper rolling friction support plate has a flat surface on the top and an arc-shaped concave surface on the bottom, while the lower rolling friction support plate has an arc-shaped concave surface on the top and a flat surface on the bottom; a spherical body is provided between the upper and lower rolling friction support plates. This bearing is a rolling friction seismic isolation bearing. The advantage is that the efficiency of the rolling friction bearing is better than that of the sliding friction bearing, and it has a reset function; the main disadvantages include: 1) the relative displacement of the upper and lower rolling friction support plates during vertical vibration cannot be controlled; 2) the stress of the spherical body between the upper and lower rolling friction support plates is concentrated at the support point, which is not as uniform as the stress distribution of the sliding friction bearing; 3) the rolling friction bearing has higher material performance requirements under long-term load than the sliding friction bearing.

[0008] 5. Laminated rubber bearings are composed of upper and lower connecting steel plates, with thin rubber plates and thin steel plates alternately stacked in between and lead rods added. This bearing is a vibration-damping bearing with the advantage of extending the force cycle through horizontal deformation of the rubber, thereby reducing the force acting on the connected object. Due to the characteristics of rubber, the bearing has a reset function after horizontal displacement. The steel plates in the laminate can change the stiffness of the bearing, and the lead rods can increase damping and reduce deformation. Laminated rubber bearings have been widely used in various fields in reality. The main disadvantages include: 1) Laminated rubber bearings have a vibration-damping effect, but do not have the seismic isolation effect of sliding friction bearings and rolling friction bearings. The force after vibration reduction cannot be determined at a single value. As the magnitude of the force greater than the initial horizontal displacement changes, the magnitude of the reduced force after vibration reduction of the laminated rubber bearing also changes accordingly. 2) Due to the use of rubber, corrosion, fire resistance, and unstable performance problems arise, and the time effect poses a threat to the service life of the laminated rubber bearing. 3) Test data show that the hysteresis curves under displacement and force are unstable.

[0009] 6. The rubber and steel sliding support consists of an upper sliding plate and a lower sliding plate. The upper and lower sliding plates have a base membrane layer on one side of the steel substrate, which is covered with a composite membrane layer. The other side of the upper and lower sliding plates has a rubber pad layer, which is connected to a flat plate for fixing. The composite membrane layers of the upper and lower sliding plates are butted together. This bearing combines vibration reduction and isolation. Its advantages lie in its complementary advantages in vibration reduction and isolation, as well as its ability to coordinate rubber deformation and sliding deformation. Its main disadvantages include: 1) It lacks a reset function, but can be used in combination with a "rubber pad shock-absorbing bearing" to achieve a parallel function of the two bearings, compensating for its lack of a reset function. 2) Because the parallel function requires the connected body to connect two bearings with different performance characteristics, stress and strain relationships between the bearings with different performance characteristics must be coordinated by the connected body. This introduces complex forces through the bearings into the connected body, changing the independent performance of the bearings. When attempting to reduce the horizontal stiffness limit of the connected body, the displacement and recovery performance of the connected body will be affected by the two bearings with different performance characteristics, and the horizontal displacement centroid and restoring force centroid of the two parallel bearings and the centroid, center of mass, and center of rigidity of the connected body will affect the normal function of both bearings. 3) Similar to the "rubber pad shock-absorbing bearing," time effects threaten the service life of the rubber-and-steel sliding bearing.

[0010] 7. Friction pendulum bearings, including an upper connecting plate with a flat connecting surface and an arc-shaped concave curved surface on the lower surface; a biconvex curved body with an upper arc-shaped convex curved surface and an arc-shaped convex curved surface on the lower surface; and a lower connecting plate with an arc-shaped concave curved surface on the upper surface and a flat connecting surface on the lower surface. The isolation and shock absorption principle of friction pendulum bearings is to dissipate seismic energy through friction at the sliding interface to achieve isolation, and to extend the natural vibration period of the structure through swinging to achieve shock absorption. Various bearing types have been developed. Its advantages are isolation, shock absorption, and reset function. Its main disadvantages include: 1) the inability to control the relative vertical displacement of the upper and lower sliding members, 2) the interference of vertical vibration on horizontal displacement, and 3) the instability of sliding stiffness and the fragility of sliding friction surfaces due to the curved sliding surface.

[0011] 8. A movable anti-separation support (patent number: ZL 2016 1 1251756.9), comprising an upper moving body and a lower supporting moving body support. Between the upper moving body and the lower supporting moving body, the lower supporting moving body is connected with a control moving block and an upper anti-separation control moving body. An anti-separation plate may be provided below the upper anti-separation control moving body. The upper moving body is connected with an anti-separation connector and a lower anti-separation moving body. An anti-separation plate may be provided above the lower anti-separation moving body. One end of the control moving block is connected to the lower supporting moving body, and the other end supports the upper moving body and is connected to the upper anti-separation control moving body. One end of the anti-separation connector is connected to the upper moving body, passes through the upper anti-separation control moving body and the anti-separation plate, and the other end is connected to the lower anti-separation moving body. This movable anti-separation support can move in any direction within a determined plane and will not separate during the movement; it can limit the displacement and displacement amount in a direction inconsistent with the moving direction, thereby improving the stability of the movement process; and it has a simple structure. There are disadvantages: 1) The use of high-rigidity steel components to control vertical displacement in the supports will produce a large vertical impact on the supports, which is not conducive to protecting the objects connected by the supports; 2) It cannot achieve vibration control and vibration reduction effects in any direction, and often requires auxiliary components to be set outside the supports to solve the problem; 3) It cannot solve the problem of additional deformation of the supports caused by uneven distribution of vertical loads on the plane. Summary of the Invention

[0012] In order to overcome the shortcomings of the existing technology, the present invention provides a friction displacement resettable support, which is installed between two external objects to be connected. On the basis of a movable anti-separation support, the performance of the support component is modified, and a disc spring component is added to resist vertical vibration and uneven distribution of vertical load on the support plane; the component that rigidly limits vertical displacement is eliminated, and a horizontal conical spring assembly is added to prevent the support from separating up and down and can return to its original position after being displaced at any angle on the upper part of the support.

[0013] The technical solution adopted by the present invention to solve its technical problem is: a friction displacement resettable support, including a support lower support member, a support inner lower support member, a control movement outer retaining ring, an intermediate clamping member, a spring small circle end clamping member, a spring large circle end clamping member, a conical spring, a disc spring and a disc spring clamping member.

[0014] The inner wall of the lower end of the movable outer retaining ring is fixedly connected to the outer wall of the support lower support member and is fixedly connected to the upper surface of the external object; the support inner lower support member is placed on the upper surface of the support lower support member;

[0015] The intermediate clamp is a cylindrical structure, and an annular groove is formed on the outer wall along the circumferential direction; the small coil end clamp of the spring is installed in the annular groove; the large coil end clamp of the spring is fixedly connected to the inner wall of the upper end of the outer retaining ring; a plurality of radial conical springs are evenly distributed between the small coil end clamp of the spring and the large coil end clamp of the spring, and the small end of the conical spring is fixedly connected to the small coil end clamp of the spring, and the large end is fixedly connected to the large coil end clamp of the spring;

[0016] The upper and lower ends of the intermediate clamp are both fixedly connected with disc springs and small diameter ends of conical springs;

[0017] The disc spring clamp is a hollow frustum structure with openings at both ends, with the large end opening fixedly connected to the upper surface of the lower support member in the support or the lower surface of the upper support member in the support; the large diameter end of the disc spring is vertically constrained by the disc spring clamp and can deform and slide horizontally when in contact with the lower support member in the support or the upper support member in the support;

[0018] The large diameter end of the conical spring connected to the upper and lower ends of the intermediate clamp is fixedly mounted on the lower surface of the support member on the support or the upper surface of the lower support member inside the support;

[0019] The upper surface of the support member on the support is fixedly connected to the lower surface of another external object, and the lower surface is placed on the upper end of the control movement peripheral retaining ring.

[0020] A friction material is provided between the lower support member inside the support and the lower support member of the support, and there is sliding friction or rolling friction between the friction material.

[0021] The outer wall of the connection between the upper support member of the support and the outer movement control retaining ring is covered with a circular ring seal.

[0022] One end of the intermediate clamp passes through the circular hole of the small diameter end of the disc spring and the small circle end of the conical spring at the same time. The clamp is used to control the disc spring and the conical spring to not separate, and the outer diameter of the small circle end of the conical spring is smaller than the inner diameter of the circular hole of the small circle end of the disc spring, so that the disc spring and the conical spring are in direct contact with the end face of the intermediate clamp.

[0023] The disc spring is composed of a plurality of single disc springs stacked or matched.

[0024] The conical spring arranged between the small coil end clamp of the spring and the large coil end clamp of the spring is an arc-shaped truncated cone spiral spring. Along the axis of the spring is a spatial straight twisted spiral line. The projection of this spiral line on the supporting surface perpendicular to the center line of the cone formed by it is an Archimedean spiral line or a logarithmic spiral line. The corresponding projection on the plane perpendicular to the supporting surface is a straight twisted ascending asymptotic line with equal pitch or a straight twisted ascending asymptotic line with equal spiral pitch angle.

[0025] The conical springs are composed of two or more stacked truncated cone coil springs.

[0026] The beneficial effects of the present invention are:

[0027] 1) The size of the external interference force is changed through the support, and the sliding displacement between two objects is used to generate sliding friction, or the rolling displacement between two components after adding a sphere to generate rolling friction. After the interference force acts on a specific part of the support determined by reliability calculation, the interference force causes the two components in the support to generate sliding friction, rolling friction and relative sliding displacement within the allowable range, and rolling displacement of the sphere. Since the size of the friction force is mainly determined by the characteristics of the contact surfaces of the two components, the diameter of the sphere, and the size of the gravity perpendicular to the friction surface, the sliding friction force will also change slightly with the temperature and displacement speed between the contact surfaces. Therefore, the friction force between the two components in the support caused by the interference force acting on the specific part of the support is a certain value range or constant; when the external interference force of unknown size acts on the specific part of the support and exceeds the value range or constant of the friction force generated between the contact surfaces of the two components in the support, the output end of the support can output a force that does not exceed the certain value range or constant of the friction force, thereby protecting the object connected to the output end of the support. At the same time, the object connected to the output end of the support can be effectively designed and calculated, thereby improving the accuracy of protecting the object connected to the output end of the support, and effectively avoiding various possible damages to the object connected to the output end of the support, which is conducive to saving construction materials and saving construction costs.

[0028] 2) By setting a truncated conical coil spring in the support, since the force of the truncated conical coil spring is a nonlinear force, the change in stiffness leads to a change in the natural frequency. Therefore, the vibration interference force will change the vibration frequency after passing through the truncated conical coil spring. In particular, after debugging, the range of natural frequency change is increased after stacking truncated conical coil springs with different parameters. When the natural frequency is in a changing state, resonance with the connection of the support under the vibration interference force can be avoided, thereby avoiding interference from adverse spectral forces.

[0029] 3) Solve the durability problem of the bearing. Different durable materials can be used according to the length of its use time. This can avoid the replacement process during use, ensure the functional requirements during use, save the manpower, material resources, financial resources and time required for the maintenance of the bearing, and there is no need to worry about the use time of the bearing during use.

[0030] 4) After realizing the force value range or numerical control of the support output end connected to the object, the uncontrollable interference force is converted into a controllable force, the probability control of the interference force is converted into a force value range or numerical control, the complicated interference force is simplified in three dimensions, and the force has a simple and clear point of action and direction of action, so as to achieve the control of the force of the support output end connected to the object through the support conversion.

[0031] 5) The materials for making the support can be organic materials such as plastics or inorganic materials such as steel and iron. When the support is required to be durable, stable, reliable and corrosion-resistant, high-strength anti-corrosion and rust-proof plastics or stainless steel materials can be used.

[0032] 6) Solve the practical problems in the current development of scientific and technological applications in the field of vibration, and create conditions for science and technology to benefit mankind, such as promoting the development of shock absorption and isolation, improving people's living standards, improving people's quality of life, protecting people's life and health, maintaining social stability, protecting social wealth security under the threat of natural disasters, promoting the development of human civilization, and promoting the accumulation of social wealth.

Under the action of a vertical force, the vertically downward supporting disc spring 5 and the lower vertical conical spring 18 simultaneously undergo vertical deformation, and the vertical heights of the vertically downward supporting disc spring 5 and the lower vertical conical spring 18 change with the magnitude of the vertical force; the lower portion of the lower vertical conical spring 18 is constrained within the concave arc surface of the vertically downward supporting disc spring 5 of the lower support member 3 in the support by the vertical connecting member of the vertically downward supporting disc spring clamping member 13.Under the vertical force, the lower end of the vertically downward supporting disc spring 5 contacts the upper surface of the lower support member 3 in the support through the vertical constraint of the vertically downward supporting disc spring clamp 13 to form a horizontal deformation and can slide; the large circle end of the lower vertical conical spring 18 is placed in the circular groove on the upper surface of the lower support member 3 in the support with the center at its center; the friction material 10 is fixed or in contact with the lower surface of the lower support member 3 in the support according to the selection of sliding friction and rolling friction, and the friction material 10 is fixed or in contact with the upper surface of the support lower support member 1, and the support lower support 1 and the control displacement After the movable outer retaining ring 2 is connected, the lower surface contacts the upper surface of the external object. After the side surface of the circular support lower support member 1 is connected with the lower inner surface of the circular controlled movable outer retaining ring 2, it is connected with the vertical connecting member provided with the corresponding lower external object through several lower support bolt holes 14 on the outer lower side of the controlled movable outer retaining ring 2; the upper end of the intermediate clamping member 6 of the horizontally supporting arc-shaped truncated cone coil spring assembly and the vertically supporting disc spring passes through the lower circular hole of the vertically supporting disc spring 7, and at the same time passes through the lower small circle end of the upper vertical conical spring 19, and is controlled by the clamping member provided at the upper end to vertically support the disc spring.

The reserved horizontal spacing should meet the requirements for the change in the radius of the circular hole at the lower end of the vertically supporting disc spring 7 under the action of vertical force.Under the action of vertical force, the vertically supporting disc spring 7 and the upper vertical conical spring 19 simultaneously produce vertical deformation, and the vertical heights of the vertically supporting disc spring 7 and the upper vertical conical spring 19 change with the magnitude of the vertical force; the upper end of the vertically supporting disc spring 7 contacts the lower surface of the support upper support member 9, and the vertically supporting disc spring clamping bolt 16 fixes the vertically supporting disc spring clamping member 8 to the support upper support member 9, and the upper end of the vertically supporting disc spring 7 is constrained by the vertically supporting disc spring clamping member 8 between the support upper support member 9 to form a horizontal deformation sliding contact between the upper end of the vertically supporting disc spring 7; the upper vertical The conical spring 19 is located in the concave arc surface of the vertical supporting disc spring 7 and the large circle end of the upper vertical conical spring 19 is placed in the circular groove with the center of the circle of the lower surface of the support upper support member 9 located at its center; the upper surface of the support upper support member 9 contacts the lower surface of the external object, and several upper support bolt holes 15 on the support upper support member 9 are connected to the vertical connecting members provided on the corresponding external object; the upper end circular periphery of the annular curved surface seal 17 is fixed below the circumferential end of the support upper support member 9 through the upper support bolt hole 15, and the lower end circular periphery of the annular curved surface seal 17 is in elastic contact with the upper end circular periphery of the control moving outer retaining ring 2.

[0058] In order to install and position the small coil end clamp 12 of the horizontal conical spring in the horizontal groove of the middle clamp 6 of the horizontally supporting arc-shaped truncated cone coil spring assembly and the vertically supporting disc spring, it can be divided into a lower vertical clamp 6-1, a lower force support and horizontal clamp 6-2, an intermediate vertical and horizontal force support 6-3, an upper force support and horizontal clamp 6-4, a threaded cylindrical connector 6-5, and an upper vertical clamp 6-6; when the conditions for installing and positioning the small coil end clamp 12 of the horizontal conical spring can be met, it is advisable to make the middle clamp 6 of the horizontally supporting arc-shaped truncated cone coil spring assembly and the vertically supporting disc spring as a whole; the importance level and material performance of the middle clamp 6 of the horizontally supporting arc-shaped truncated cone coil spring assembly and the vertically supporting disc spring in the core position are higher than those of other components; the radius R6 of the middle clamp 6 of the horizontally supporting arc-shaped truncated cone coil spring assembly and the vertically supporting disc spring is ≤ the radius R5 of the lower support 3 in the support.

[0059] The vertically downward supporting disc spring 5 is assembled by stacking and matching single disc springs; the vertically upward supporting disc spring 7 is assembled by stacking and matching single disc springs.

[0060] The horizontally arcuate truncated conical coil spring in the horizontally arcuate truncated conical coil spring assembly 4 can be composed of two or more truncated conical coil springs with different parameters such as helix angle, pitch, wire diameter, cone angle, diameter size at both ends of the truncated conical coil spring, and the oblique straight line between the pitch is changed to a horizontal arc with the same curvature, and the horizontally arcuate truncated conical coil springs are stacked together, which can change the force and natural frequency of the horizontally arcuate truncated conical coil spring assembly 4; the lower vertical conical spring 18 and the upper vertical conical spring 19 can both be composed of two or more truncated conical coil springs with different parameters such as helix angle, pitch, wire diameter, cone angle, and diameter size at both ends of the truncated conical coil spring.

[0061] The combined elasticity and shear force Fs of the horizontal arc-shaped truncated cone coil spring assembly 4 in the friction direction is greater than the maximum friction force Ff between the lower surface of the lower support member 3 in the support due to the friction material 10 and the upper surface of the lower support member 1 of the support.

[0062] Since the components in the middle part of the friction displacement resettable support connecting the lower support member 1, the upper support member 9, and the controlled movable outer retaining ring 2 are all elastic and shear deformation components, in three-dimensional space, let α be the angle between the displacement and the horizontal plane, 0≤α≤π / 2, so that the lower support member 1 and the upper support member 9 of the friction displacement resettable support can achieve relative displacement and reset in any direction in the three-dimensional space on the horizontal plane.

[0063] The friction displacement resettable bearing provided by the embodiments of the present invention is an elastic, anti-detachment bearing capable of resetting the vertical and horizontal vibrations of a connected object, as well as resetting the vibrations at any angle between the vertical and horizontal directions. The bearing is suitable for vibration control bearings for architectural structures and mechanical equipment with vibration requirements, for bearings for highway and railway bridges, for active and passive control bearings installed in aviation and aerospace equipment, and for active and passive control bearings installed in pipelines and lines. The present invention can reduce the forces exerted by vertical and horizontal vibrations, protecting the connected object, and is applicable to fields with a wide range of vertical and horizontal vibrations, as well as vibrations at any angle between the vertical and horizontal directions.

[0064] The friction displacement resettable support is composed of three parts: a horizontal arc-shaped truncated cone coil spring assembly 4, a horizontal conical spring large circle end clamp 11, and a horizontal conical spring small circle end clamp 12 to form a horizontal elastic member; the horizontal conical spring small circle end clamp 12 is connected to the intermediate clamp 6 of the horizontal supporting arc-shaped truncated cone coil spring assembly and the vertical supporting disc spring, and the upper end of the threaded cylindrical connecting piece 6-5 of the horizontal supporting arc-shaped truncated cone coil spring assembly and the vertical supporting disc spring passes through the lower circular hole of the vertical supporting disc spring 7 and the small circle end of the upper vertical conical spring 19 at the same time and is controlled by the upper vertical clamp 6-6 at its end to prevent it from disengaging; the horizontal supporting arc-shaped truncated cone coil spring assembly and the vertical supporting disc spring are connected to each other. The lower end of the threaded cylindrical connector 6-5 of the middle clamp 6 of the disc spring supports passes through the upper circular hole of the vertically downward supporting disc spring 5 and the small circle end of the vertical conical spring 18 at the same time and is controlled by the lower vertical clamp 6-1 at its end to prevent it from disengaging; after the above-mentioned connection combination, the eight components of the horizontal arc-shaped truncated cone coil spring assembly 4, the horizontal conical spring large circle end clamp 11, the horizontal conical spring small circle end clamp 12, the horizontal supporting arc-shaped truncated cone coil spring assembly and the middle clamp 6 of the vertical supporting disc spring, the vertically upward supporting disc spring 7, the upper vertical conical spring 19, the vertically downward supporting disc spring 5, and the vertical conical spring 18 form an elastic deformation integrated core body in any direction located in the middle of the friction displacement resettable support.

[0065] The present invention comprises a plurality of arc-shaped truncated cone coil springs forming a horizontal arc-shaped truncated cone coil spring assembly 4, wherein the cone center lines of each arc-shaped truncated cone coil spring intersect at a circle center O with a radius of R1, and the arc-shaped small circle ends of each arc-shaped truncated cone coil spring overlap on a circle with a radius of R1, and the arc-shaped large circle ends of each arc-shaped truncated cone coil spring overlap on a concentric circle with a radius of R1, and the radius of the concentric circle R2>R1. The horizontal length of each horizontally placed arc-shaped truncated cone coil spring is the value of R2-R1, forming a circular ring between R1 and R2 on the horizontal plane, in which a plurality of horizontal arcs are arranged around the circle center O. The horizontal arc truncated cone coil spring assembly 4 of the truncated cone coil spring, the force of the horizontal arc truncated cone coil spring assembly 4 is the resultant force of multiple horizontal arc truncated cone coil springs, the natural frequency characteristic of the horizontal arc truncated cone coil spring assembly 4 is the comprehensive natural frequency characteristic after multiple horizontal arc truncated cone coil springs are connected in parallel, when different resultant force and natural frequency characteristics of the horizontal arc truncated cone coil spring assembly 4 are required, the force and natural frequency characteristics of each horizontal arc truncated cone coil spring can be adjusted, at this time, each horizontal arc truncated cone coil spring in the horizontal arc truncated cone coil spring assembly 4 can be The angles between the center lines of the parallel horizontal arc-shaped truncated cone coil springs can be the same or different; the arc-shaped large end of each arc-shaped truncated cone coil spring is positioned and fixed by the horizontal conical spring large circle end clamp 11, and after the horizontal conical spring large circle end clamp 11 is connected to the control movement outer retaining ring 2, it will not be deformed due to the deformation of the horizontal arc-shaped truncated cone coil spring assembly 4; the arc-shaped small end of each arc-shaped truncated cone coil spring in the horizontal arc-shaped truncated cone coil spring assembly 4 is positioned and fixed by the horizontal conical spring small circle end clamp 12, and the horizontal conical spring small circle end clamp 12 is connected to the horizontal After the intermediate clamp 6 for the horizontally supporting arc-shaped truncated cone coil spring assembly and the vertically supporting disc spring is connected, it will not be deformed due to the deformation of the horizontally supporting arc-shaped truncated cone coil spring assembly 4; the assembly formed after the horizontally supporting arc-shaped truncated cone coil spring assembly large circle clamp 11, the horizontally supporting arc-shaped truncated cone coil spring assembly 4, and the horizontally supporting disc spring small circle clamp 12 are connected can form finished products with different characteristics and models due to the differences in the horizontally supporting arc-shaped truncated cone coil spring assembly 4. After the finished products are formed, they are easy to package, place, transport, and install. They can be installed in different supports according to the required characteristics and models to meet different requirements, forming unique products.

[0066] Since the support is circular, an arc-shaped truncated conical coil spring different from the truncated conical coil spring is required. Generally, the material axis of the truncated conical coil spring is a straight spatial twisted spiral line. The projection of this spiral line on the support surface perpendicular to the center line of the cone formed by it is an Archimedean spiral or a logarithmic spiral. The corresponding projection on the plane perpendicular to the support surface is a straight twisted ascending asymptotic line with equal pitch or a straight twisted ascending asymptotic line with equal spiral pitch angle. After the truncated conical coil spring is compressed, it is a plane. The material axis of the arc-shaped truncated conical coil spring is an arc-shaped twisted spatial spiral line. The projection of this spiral line on the support surface perpendicular to the center line of the cone formed by it is an Archimedean spiral or a logarithmic spiral. The corresponding projection on the plane perpendicular to the support surface is an arc-shaped twisted ascending asymptotic line with equal pitch or an arc-shaped twisted ascending asymptotic line with equal spiral pitch angle. After the arc-shaped truncated conical coil spring is compressed, it is an arc surface. Since the arc between two points is longer than a straight line, under the same other conditions, the material of the arc-shaped truncated conical coil spring is The total length of the material is greater than the total length of the material of the truncated cone coil spring. When the small end curvature radius, the large end curvature radius, and the single spring diameter remain unchanged, the total deformation energy of the arc-shaped truncated cone coil spring is greater than the total deformation energy of the truncated cone coil spring. When the shape constants of the arc-shaped truncated cone coil spring are: the large end radius r1, the small end radius r2, the single spring diameter d, the number of working turns n, the angle θ between the line connecting r1 to r2 and the center line, as the height of the arc-shaped truncated cone coil spring changes, the range of the angle θ is: 0<θ≤π / 2, and it is known that the arc-shaped truncated cone coil spring The condition for complete compression when the spring is vertically set is: r2-r1≥nd, then the condition for complete compression when the arc-shaped truncated cone coil spring is horizontally placed is: r1-r2≥nd+∑δi+∑λi; among them, δi represents the maximum vertical deflection generated vertically downward by each spring coil, λi represents the relative vertical displacement between the small end and the large end of the arc when vertical shear deformation occurs in the horizontally placed state of the arc-shaped truncated cone coil spring, and the upper and lower vertical displacements λi of each spring coil relative to the horizontal position, and i represents each working spring coil.

[0067] The vertically upward supporting disc spring 7 in the support bears the vertical downward force and horizontal force of the upper support member 9 of the support, and the vertical upward force and horizontal force of the horizontally supporting conical spring and the intermediate clamp 6 of the vertically supporting disc spring. The material strength and composition parameter values of the vertically upward supporting disc spring 7 are determined by the relationship between the vertical load and deformation of the single-leaf disc spring and the relationship between the horizontal load and shear section of the single-leaf disc spring; the vertically downward supporting disc spring 5 in the support bears the vertical upward force and horizontal force of the lower support member 3 in the support, and the vertical downward force and horizontal force of the horizontally supporting conical spring and the intermediate clamp 6 of the vertically supporting disc spring. The material strength and composition parameter values of the vertically downward supporting disc spring 5 are determined by the relationship between the vertical load and deformation of the single-leaf disc spring and the relationship between the horizontal load and shear section of the single-leaf disc spring. Because the vertically supporting disc spring 7 and the vertically supporting disc spring 5 bear not only vertical forces but also horizontal forces, their calculation and design are different from those of a typical disc spring that only bears vertical forces. Finite element methods can be used to calculate the deformation and stress values of the disc springs under vertical and horizontal forces, and existing disc spring data, information testing, and geometric data for the disc springs can be used to design the disc springs, as well as the allowable number of load variations. Alternatively, a formula for calculating the stress at the disc spring's most unfavorable point under vertical load can be used to calculate the maximum combined stress and the allowable number of load variations of the stress at the disc spring's most unfavorable point under horizontal forces, and existing disc spring data, information testing, and geometric data for the disc springs can be used to design the disc springs. The thickness of the typical vertically supporting disc spring 7 and the vertically supporting disc spring 5 is greater than that of a typical disc spring that only bears vertical forces.

[0068] The friction material 10 can be divided into: 1. rolling friction material 10-1, which is composed of a spherical assembly, such as a high-strength rust-proof steel ball assembly and a high-strength polymer organic material spherical assembly; 2. sliding friction material 10-2, which is sprayed, fixed, and set on the upper surface of the support member 1 under the support and the lower surface of the support member 3 under the support, respectively, with a sliding friction material coating, such as molybdenum disulfide, graphene, and lubricant.

[0069] The intermediate clamp 6 of the horizontal supporting arc-shaped truncated cone coil spring assembly and the vertical supporting disc spring is a key component for transmitting multi-directional forces, embedding and connecting components deforming in various directions, and requires high strength and good connection component performance. The radius R6 of the intermediate clamp 6 of the horizontal supporting arc-shaped truncated cone coil spring assembly and the vertical supporting disc spring is ≤ the radius R5 of the lower support member 3 in the support; because the intermediate clamp 6 of the horizontal supporting arc-shaped truncated cone coil spring assembly and the vertical supporting disc spring has the function of embedding the small circle end clamp 12 of the horizontal conical spring, and at the same time, in order to facilitate processing, installation and save materials, the intermediate clamp 12 of the horizontal supporting arc-shaped truncated cone coil spring assembly and the vertical supporting disc spring is The intermediate clamp 6 can be divided into the lower vertical clamp 6-1, the lower force support and horizontal clamp 6-2, the middle vertical and horizontal force support 6-3, the upper force support and horizontal clamp 6-4, the threaded cylindrical connector 6-5, and the upper vertical clamp 6-6. After they are processed separately, the intermediate clamp 6 of the horizontal support arc truncated cone coil spring assembly and the vertical support disc spring is formed through the connecting action of the threaded cylindrical connector 6-5, thereby solving the technical problems that the intermediate clamp 6 of the horizontal support arc truncated cone coil spring assembly and the vertical support disc spring is difficult to process, waste materials, difficult to install in the support, and difficult to embed the small circle end clamp 12 of the horizontal conical spring.

[0070] The vertically downward supporting disc spring 5 can be assembled by stacking and matching single disc springs; the vertically upward supporting disc spring 7 can be assembled by stacking and matching single disc springs. When the vertical and horizontal bearing capacities of a single disc spring are relatively low, a stacked single disc spring can be used to increase these capacities. The increased vertical and horizontal capacities of the stacked disc springs are the sum of the vertical and horizontal capacities of the single disc springs. When the vertical deformation of a single disc spring is relatively low, a matched single disc spring can be used to increase this deformation. The increased vertical deformation of the matched disc springs is the sum of the vertical deformations of the single disc springs. The vertically downward supporting disc spring 5 and the vertically upward supporting disc spring 7 are combined by overlapping and matching single-piece disc springs, which can solve the parameter standards that single-piece disc springs cannot achieve, and can make the spring characteristics vary within a large range, thereby technically expanding the scope of use of the friction displacement resettable support, so that the friction displacement resettable support can more effectively and accurately solve the application problems encountered.

[0071] Each horizontal arc-shaped truncated conical coil spring in the horizontal arc-shaped truncated conical coil spring assembly 4 can be composed of two or more horizontal arc-shaped truncated conical coil springs with different parameters; the lower vertical conical spring 18 and the upper vertical conical spring 19 can both be composed of two or more truncated conical coil springs with different parameters; the horizontal arc-shaped truncated conical coil spring assembly 4 is composed of horizontal arc-shaped truncated conical coil springs, and the lower vertical conical spring 18 and the upper vertical conical spring 19 are composed of truncated conical coil springs, which can solve the parameter standards that cannot be achieved by a single arc-shaped truncated conical coil spring or a single truncated conical coil spring, and can make the spring characteristics vary within a wide range, thereby technically expanding the scope of use of the friction displacement resettable support, so that the friction displacement resettable support can more effectively and accurately solve the application problems encountered and adjust the constraint stiffness of the support. Using the "Calculation Formula for Equal-Pitch Frustum-Conical Coil Springs" or "Calculation Formula for Equal-Helix-Angle Frustum-Conical Coil Springs," the geometric dimensions and force parameters of the stacked lower vertical conical springs 18 and upper vertical conical springs 19 can be calculated. Because the total energy of a spring is a function of its constituent material type, volume, stress characteristics, and spring type, the geometric dimensions and force parameters of each horizontally curved truncated conical coil spring assembly 4 can be determined based on the required total energy. The overall dimensions of the horizontally curved truncated conical coil spring assembly 4, lower vertical conical spring 18, and upper vertical conical spring 19 are constrained by the structural dimensions of the support.

[0072] The relative displacement length L0 of the support lower support member 1 and the support upper support member 9 controls the relative distances L1 and L2 between the movable outer retaining ring 2 and the support inner lower support member 3. When L0=0, the length L1=L2 is the standard displacement length L of the friction displacement resettable support. When L1≠0, L1>L2 or L2>L1 appears, L=(L1+L2) / 2; in order to accurately represent the displacement state, the displacement ratio is taken: λ=L0 / L. When λ=0, L0=0, and there is no relative displacement between the support lower support member 1 and the support upper support member 9. When 0<λ<1, the support The relative displacement of the support member 1 under the seat and the support member 9 on the support is 0<L0<L. When λ=1, the relative displacement of the support member 1 under the seat and the support member 9 on the support is L0=L, which is the relative maximum displacement of the support member 1 under the seat and the support member 9 on the support. Therefore, the horizontal displacement state of the friction displacement resettable support can be expressed by the horizontal displacement ratio: λ=L0 / L. The value of the standard displacement length L indicates the maximum horizontal displacement of the friction displacement resettable support, which is the basic parameter of the friction displacement resettable support; the collision between the outer retaining ring 2 and the lower support member 3 inside the support is controlled. It will cause the friction displacement resettable support to enter an abnormal use state. In order to avoid the collision between the controlled moving outer retaining ring 2 and the lower support member 3 in the support, the constraint condition of the horizontal displacement of the friction displacement resettable support is L0≤L. Under the constraint condition L0≤L, the maximum length L3 of the combined horizontal elastic compression and stretching of the horizontal arc-shaped truncated cone coil spring assembly 4 in the same direction as the displacement must be controlled. When the maximum length L3 of the combined horizontal elastic compression and stretching of the horizontal arc-shaped truncated cone coil spring assembly 4 is controlled to be ≤L, the controlled moving outer retaining ring 2 and the support can be prevented from colliding. When the lower support member 3 in the seat collides, the length of elastic compression and extension of the horizontally oriented arcuate truncated conical coil spring assembly 4 in the assembly direction is L3 = ∑Δi, where Δi = fα. P is the deformation of the i-th arcuate truncated conical coil spring in the assembly 4, which is elastically compressed, stretched, and sheared. Here, fα is a calculation formula that determines the shape parameters and stiffness of the arcuate truncated conical coil spring, and P is the force causing the compression and extension of the arcuate truncated conical coil spring. In a friction displacement resettable bearing, L3 = L0, and the maximum value of L3 and L0 is L. The external dimensions of the horizontally oriented arcuate truncated conical coil spring assembly 4 are constrained by the structural dimensions of the bearing.

[0073] Under the vertical forces of P1 and P2, the vertical downward supporting disc spring 5, the vertical upward supporting disc spring 7, the lower vertical conical spring 18, the upper vertical conical spring 19, and the horizontal arc-shaped truncated cone coil spring assembly 4 produce vertical elastic and shear deformations. The connection between the horizontal supporting arc-shaped truncated cone coil spring assembly and the middle clamp 6 of the vertical supporting disc spring causes the relative vertical displacement h2 between the support lower support member 1 and the support upper support member 9. Under the horizontal forces of Q1 and Q2, the horizontal arc-shaped truncated cone coil spring assembly 4 produces The length L3 of the combined horizontal elastic compression and stretching, the connection effect of the intermediate clamp 6 of the horizontal supporting arc-shaped truncated cone coil spring assembly and the vertical supporting disc spring causes the relative horizontal displacement L0 of the support lower support member 1 and the support upper support member 9; under the combined action of the vertical forces P1 and P2 and the horizontal forces Q1 and Q2, the vertical downward supporting disc spring 5, the vertical upward supporting disc spring 7, the lower vertical conical spring 18, the upper vertical conical spring 19, and the horizontal arc-shaped truncated cone coil spring assembly 4 are elastically displaced. The connection between the horizontal supporting arc truncated cone coil spring assembly and the vertical supporting disc spring 6 causes the relative displacement H between the support lower support 1 and the support upper support 9. H is the vector sum of h2 and L0. The angle α between H and the horizontal plane will change when any one of h0, L0 and α changes. Due to the friction displacement, the vertical downward supporting disc spring connected by the intermediate clamp 6 of the horizontal supporting arc truncated cone coil spring assembly and the vertical supporting disc spring in the middle of the support can be reset. 5. The vertical supporting disc spring 7, the lower vertical conical spring 18, the upper vertical conical spring 19, and the horizontal arc-shaped truncated cone coil spring assembly 4 are all elastic and shear-deformable components, so that the upper support member 9 of the support is located under the support of the three-dimensional elastic and shear components, realizing the technical requirements of resettable displacement within the elastic and shear deformation range of 0≤α≤2π in three-dimensional space, so that the lower support member 1 and the upper support member 9 of the friction displacement resettable support can realize the technical characteristics of relative displacement, limitation and reset in any direction in three-dimensional space.

[0074] When the vertical force W2 acting on the upper support member 9 of the support under the action of vertical vibration is greater than the vertical force W1 acting on the lower support member 1 of the support, due to the elastic and shear deformation effects of the vertical downward supporting disc spring 5, the vertical upward supporting disc spring 7, the lower vertical conical spring 18, the upper vertical conical spring 19, and the horizontal arc-shaped truncated cone coil spring assembly 4, part of the gravitational potential energy generated by W2 is converted into elastic and shear deformation energy, thereby reducing the mutual impact force of the vertical vibration on the external connector of the upper support member 9 and the external connector of the lower support member 1 of the support, and has the technical feature of protecting the external connector of the support.

[0075] To achieve resettable displacement, the elasticity and shear deformation of the vertical downward supporting disc spring 5, vertical upward supporting disc spring 7, lower vertical conical spring 18, upper vertical conical spring 19, and horizontal arcuate truncated cone coil spring assembly 4 must be controlled within the allowable elasticity and shear design strength of the materials used. The forces acting on the intermediate clamp 6 interacting between the horizontal arcuate truncated cone coil spring assembly and the vertical supporting disc springs must also be controlled within a restricted range. To achieve resettable friction displacement, the technical characteristic of the combined elasticity and shear force Fs of the horizontal arcuate truncated cone coil spring assembly 4 in the friction direction must be greater than the maximum friction force Ff between the lower surface of the support inner lower support member 3 due to friction material 10 and the upper surface of the support lower support member 1 must be met. For the force F1 acting on the support lower support member 1 to achieve the force F2 acting on the support upper support member 9 less than F1, the following conditions must hold: Fs + Ff < F1. Due to the structural characteristics of the support, the technical characteristic of the force required for reset after vibration isolation and displacement can be achieved; otherwise, reset will not occur.

[0076] The friction displacement resettable support has an upper circumferential portion of a circular curved surface seal 17 fixed below the circumferential end of the upper support member 9 through the upper support bolt hole 15, and the lower circumferential edge of the circular curved surface seal 17 is in elastic contact with the upper end of the controlled movable outer retaining ring 2, thereby achieving the technical requirements for sealing the interior of the friction displacement resettable support.

[0077] The friction displacement resettable support described above does not have a vertical downward supporting disc spring 5, a vertical downward supporting disc spring clip 13, and a lower vertical conical spring 18 at the lower end of the lower support member 6 in the support that horizontally connects the conical spring and the vertically supporting disc spring. The lower end of the lower support member 6 in the support that horizontally connects the conical spring and the vertically supporting disc spring is directly connected to the lower support member 3 in the support by a hinged method, and other components remain unchanged. In this support form, the support height is reduced and the structure is simplified.

[0078] The friction displacement resettable support is made of different materials according to the requirements of use. For example, if high-strength rust-proof steel is used, it has the characteristics of durability, stability, firmness and high strength. Special organic materials can also be used, which have the characteristics of corrosion resistance, light weight and easy processing. The various components that make up the support can be made of materials with different characteristics. The control movement outer retaining ring 2 and the lower support member 3 inside the support can be designed and calculated according to the instantaneous impact strength requirements. After the displacement of the support exceeds the limit design value, the control movement outer retaining ring 2 and the lower support member 3 inside the support can effectively prevent the support from over-displacement in any direction, maintain the effective function of the support in supporting the object connected to the support, and achieve the effective defense function of the second component to protect the object connected to the support under the extreme action of over-displacement.

[0079] The present invention can meet the needs of shock absorption and seismic isolation. It is an integral support that can elastically limit three-dimensional displacement and has horizontal, upper and lower elastic connections that do not separate during elastic deformation. It also has the function of returning to a relative equilibrium position after three-dimensional displacement.

[0080] The present invention can elastically limit the movement in the three-dimensional moving direction, improve the stability of the three-dimensional movement, and avoid collision of the support components within the three-dimensional design range;

[0081] The present invention can move in the permissible horizontal direction and limit the displacement, and has a clear structural function. Due to the use of the horizontally arcuate truncated conical coil spring assembly 4, all the spring coils of the truncated conical coil spring can fall on the support after compression, and the compression height Hb=d(the diameter of the truncated conical coil spring material), compressibility, lateral stability, variable stiffness, and high rate of change of natural frequency can eliminate and alleviate resonance. After fully utilizing the characteristics of the truncated conical coil spring, the support has the characteristics of horizontal reset and a larger permissible horizontal displacement, thereby reducing the size of the support.

[0082] Changing the circular cross-section of a truncated conical coil spring to a rectangular cross-section effectively reduces the height of the support. Changing the coils of a truncated conical coil spring from circular to rectangular, while maintaining the total length of the spring, allows the shorter vertical sides of the coils to be smaller than the radius of the coils when placed horizontally. This effectively reduces the height of the support when the spring is placed horizontally.

[0083] The present invention can move in the allowable vertical direction and limit the displacement, and the structural function is clear. Due to the use of vertical downward supporting disc springs 5, vertical upward supporting disc springs 7, lower vertical conical springs 18, and vertical conical springs 19, the force uniformity and stability of the lower support member 3 in the support and the upper support member 9 of the support can be adjusted. When the upper support member 9 and the lower support member 1 of the support undergo upward and downward relative vertical displacement, an elastic force is generated, and the vertical external force is stored and converted in the form of elastic potential energy, thereby avoiding vertical collision of the support components and reducing the interaction force between external objects connected to the upper and lower parts of the support.

[0084] The lower support member 1 of the support and the upper support member 9 of the support can move vertically relative to each other while moving horizontally relative to each other. The upper support member 9 of the support can also move relative to the lower support member 1 in the direction of any acute angle with the horizontal plane. The horizontal arc-shaped truncated cone coil spring assembly 4 generates elastic and shear deformation forces when the upper support member 9 and the lower support member 1 of the support are displaced vertically relative to each other, which can control the upper support member 9 and the lower support member 1 to not separate and return to their original positions during the relative vertical movement. The interaction of the horizontal arc-shaped truncated cone coil spring assembly 4, the vertical downward supporting disc spring 5, the vertical upward supporting disc spring 7, the lower vertical conical spring 18, and the upper vertical conical spring 19 can prevent the support components from colliding within the range of allowed movement in the horizontal, vertical, and directions of any acute angle with the horizontal plane, so that the support has overall elastic properties.

[0085] While allowing movement in any direction, the upper support member 9 and the lower support member 1 of the support have the function of automatically restoring the original equilibrium state when they are displaced vertically relative to each other, and the restoring force is an elastic, continuous and stable process. When the force acting on the support is a vertical reciprocating force, the restoring force is also vertically reciprocating.

[0086] While allowing movement in any direction, the upper support member 9 and the lower support member 1 of the support have the function of automatically restoring the original equilibrium state when they are displaced horizontally relative to each other, and the recovery function is an elastic, continuous and stable process. When the force acting on the support is a horizontal reciprocating force, the restoring force is also horizontally reciprocating.

[0087] The nature of the relative horizontal movement between the upper support member 9 and the lower support member 1 of the support: When the friction material 10 between the lower support member 1 of the support and the inner lower support member 3 of the support is set as a rolling friction spherical body assembly 10-1, such as a high-strength rust-proof steel spherical body, the relative horizontal movement is rolling friction;

[0088] The nature of the horizontal movement of the upper support member 9 and the lower support member 1 of the support: when the friction material 10 between the lower support member 1 of the support and the inner lower support member 3 of the support is set to sliding friction 10-2, a sliding coating is respectively provided on the upper surface of the lower support member 1 and the lower surface of the inner lower support member 3 of the support, and a sliding material such as molybdenum disulfide or graphene is provided. The relative horizontal movement is sliding friction;

[0089] The upper support member 9 of the support and the lower support member 3 inside the support are connected by the lower vertical conical spring 18 and the upper vertical conical spring 19, so that the upper support member 9 and the lower support circular moving member 3 can move along the contact surface respectively to avoid unnecessary rigid connection and rigid collision between the support components, and protect the stable connection between the components.

[0090] When the circular support lower support member 1 and the circular controlled movable outer retaining ring 2 are subjected to the horizontal force F1 and are connected to the external objects, a horizontal displacement is generated. Since the upper inner peripheral surface of the controlled movable outer retaining ring 2 is connected to the horizontal arc-shaped truncated cone coil spring assembly 4, the horizontal arc-shaped truncated cone coil spring assembly 4 produces elastic compression and elongation deformation, and then acts on the connected horizontal support arc-shaped truncated cone coil spring assembly and the vertical support disc spring intermediate clamping member 6 with a force F1s. The direction of action of the elastic force F1s of the horizontal arc-shaped truncated cone coil spring assembly 4 is always the center of the circular support. At the same time, since the lower surface of the lower support member 3 in the support is fixed and in contact with the friction material 10, the bottom of the friction material 10 is fixed and in contact with the upper surface of the support lower support member 1. When the circular support lower support member 1 and the circular controlled movable outer retaining ring 2 are subjected to the horizontal force F1 and are connected to the external objects, a horizontal displacement is generated. , the lower support member 3 in the support is subjected to the friction force Ff, and the friction force Ff is transmitted to the horizontal supporting arc-shaped truncated cone coil spring assembly and the middle clamp 6 of the vertical supporting disc spring through the vertical downward supporting disc spring 5. In the horizontal direction, the horizontal supporting arc-shaped truncated cone coil spring assembly and the middle clamp 6 of the vertical supporting disc spring are subjected to the forces F1s and Ff, and the force is transmitted to the upper support member 9 of the support and the external connected object through the vertical upward supporting disc spring 7; when F1s>Ff, the upper support member 9 of the support and the lower support member 1 of the support and the controlled movable outer retaining ring 2 have the ability to restore to their initial positions after relative horizontal displacement; because F1s of the horizontal supporting arc-shaped truncated cone coil spring assembly and the middle clamp 6 of the vertical supporting disc spring and Ff of the lower support member 3 in the support are definite vector sums, the force acting on the upper support member 9 of the support is a value with definite direction and magnitude. Due to the effect of the friction material 10, when F1>F1s>Ff, F1>F1s+Ff, the friction displacement resettable support reduces the force of F1 and has the function of restoring the support to its original position.

[0091] When the lower support member 1 of the support, the controlled movable outer retaining ring 2, and the upper support member 9 of the support are subjected to vertical action on the upper and lower external connection objects, they move vertically relative to the lower support member 3 inside the support, the horizontally supporting arc-shaped truncated cone coil spring assembly, and the intermediate clamping member 6 of the vertically supporting disc spring, under the connecting action of the controlled movable outer retaining body 2, the elasticity and shear deformation performance of the horizontally supporting arc-shaped truncated cone coil spring assembly 4 limit the vertical movement of the intermediate clamping member 6 of the horizontally supporting arc-shaped truncated cone coil spring assembly and the vertically supporting disc spring and restore it to its original position. Through the intermediate clamping member 6 of the horizontally supporting arc-shaped truncated cone coil spring assembly and the vertically supporting disc spring, the vertically upward supporting disc spring 7, the upper vertical conical spring 19, the vertically downward supporting disc spring 5, and the lower vertical conical spring 18, the purpose of limiting the vertical movement and resetting of the upper support member 9 of the support relative to the lower support member 1 and the controlled movable outer retaining ring 2 is achieved.

[0092] The support lower support member 1 and the control movement outer retaining ring 2 are supported, transmitted and connected by the support inner lower support member 3, the horizontal support arc truncated cone coil spring assembly and the vertical support disc spring intermediate clamp 6, the vertical upward support disc spring 7, the upper vertical conical spring 19, the vertical downward support disc spring 5 and the lower vertical conical spring 18. Under the action of elastic and shear connection, the support upper support member 9 is in the three-dimensional force field of elastic and shear deformation, so that the support lower support member 1 and the control movement outer retaining ring 2 and the support upper support member 9 have the function of three-dimensional deformation and restoration of balance.

[0093] When the lower support member 1 of the support, the controlled movable outer retaining ring 2, and the upper support member 9 of the support are subjected to vertical action on the upper and lower external connection objects, they undergo relative vertical elastic deformation and shear deformation with the lower support member 3 inside the support, the vertical downward supporting disc spring 5, the lower vertical conical spring 18, the horizontal supporting arc-shaped truncated cone coil spring assembly and the intermediate clamp 6 of the vertical supporting disc spring, the horizontal arc-shaped truncated cone coil spring assembly 4, the vertical upward supporting disc spring 7, and the upper vertical conical spring 19. The upper support member 9 of the support prevents rigid collision with the lower support member 1 of the support through elastic deformation and shear deformation, realizes elastic action without component collision, avoids collision of the lower support member 1, the controlled movable outer retaining ring 2, and the upper support member 9 with the upper and lower external connection objects, and the process of elastic deformation and shear deformation realizes the process of reducing the interaction force of the upper and lower external connection objects.

[0094] The non-fixed connection between the vertically upward supporting disc spring 7, the upper vertical conical spring 19 and the lower support 6 in the support that connects the horizontal conical spring and the vertically supporting disc spring automatically adjusts the contact surface between the upper support 9 of the support and the external connecting body; the non-fixed connection between the vertically downward supporting disc spring 5, the lower vertical conical spring 18 and the lower support 6 in the support that connects the horizontal conical spring and the vertically supporting disc spring automatically adjusts the contact surface between the upper support 3 in the support and the friction material 10, avoiding uneven stress and secondary stress on the contact surface or causing the support to lose its function; realizing the process of non-human adjustment of the contact surface.

[0095] When the lower support member 1 of the support and the controlled movable outer retaining ring 2 and the external connection object are subjected to horizontal action, the friction force acting on the lower support member 3 inside the support and the horizontal elastic force of the horizontal arc-shaped truncated cone coil spring assembly 4 are transmitted horizontally to the upper support member 9 of the support through the intermediate clamp 6 of the horizontal support arc-shaped truncated cone coil spring assembly and the vertical support disc spring, the vertical downward support disc spring 5, and the vertical upward support disc spring 7, so that the force acting on the upper support member 9 of the support is less than the horizontal force requirement of the lower support member 1 of the support and the controlled movable outer retaining ring 2 and the external connection object, that is, the force acting on the upper support member 9 of the support on the connection external object is adjusted.

[0096] The present invention can elastically reduce vertical vibration, change the vertical vibration frequency, and change the vertical force value. The characteristic coefficients of the vertical downward supporting disc spring 5, the lower vertical conical spring 18, the vertical upward supporting disc spring 7, and the upper vertical conical spring 19 can be adjusted as required, and the number of disc springs and conical springs can be increased to achieve the requirements of adjusting the vertical vibration characteristics and adjusting the bearing capacity.

[0097] The present invention can elastically reduce horizontal vibration, change the horizontal vibration frequency, change the horizontal force value, and adjust the horizontal vibration data as required. For example, by adjusting the parameters of the arcuate truncated conical coil springs in the horizontal arcuate truncated conical coil spring assembly 4 and combining multiple different arcuate truncated conical coil springs in a stacked manner, the natural frequency can be changed, resonance can be eliminated, and the vibration period can reach the required value.

[0098] Under the action of vertical force, the outer retaining ring 2 and the external objects connected to the support lower support 1 are prevented from being separated from each other. Under the action of horizontal force, the outer retaining ring 2 and the external objects connected to the support lower support 1 are prevented from being separated from each other.

[0099] The present invention can achieve deformation and vibration reduction in any angle between vertical and horizontal directions within the range of elastic deformation and shear deformation, and can change the vibration frequency and force value in this direction as required.

[0100] The present invention can automatically reset vertically elastically. After the external force disappears, the support returns to its original position. The displacement of the vertical reciprocating force generated by external vibration can be automatically reset continuously, and collision of the internal components of the support can be avoided.

[0101] The invention can automatically reset horizontally elastically. After the external force disappears, the support returns to its original position. The displacement of the horizontal reciprocating force generated by external vibration can be automatically reset continuously and avoid collision of components inside the support.

[0102] The friction material 10 is fixed and in contact between the inner surface of the support lower support member 1 and the lower surface of the support inner lower support member 3; when the friction material 10 is set as a rolling friction material 10-1 as needed, when the support lower support member 1 is subjected to an external force F1, the support inner lower support member 3 is subjected to a rolling friction force Ff.

[0103] A friction material 10 is arranged between the inner surface of the support lower support member 1 and the lower surface of the support inner lower support member 3; when the friction material 10 is fixed to the sliding friction material 10-2 as needed, when the support lower support member 1 is subjected to the external force F1, the support inner lower support member 3 is subjected to the sliding friction force Ff.

[0104] The vertically upward supporting disc spring 7 is slidably connected to the lower support member 6 in the support that connects the horizontal conical spring and the vertically supporting disc spring, and the contact surface between the upper support member 9 of the support and the external connecting body is elastically adjusted; the vertically downward supporting disc spring 5 is slidably connected to the lower support member 6 in the support that connects the horizontal conical spring and the vertically supporting disc spring, and the contact surface between the upper support member 3 in the support and the friction material 10 is elastically adjusted, so as to avoid uneven stress, secondary stress or loss of function of the support on each contact surface; without the need for manual adjustment.

[0105] Under the action of the vertical and horizontal variable periodic reciprocating impact forces W1 and F1 acting on the controlled movable outer retaining ring 2 and the support member 1 under the support, the 'friction displacement resettable support' can effectively protect the functional integrity of the external objects connected by the support, and automatically adjust the vertical and horizontal forces acting on the support member 9 and the external connection body to a value within a controllable range, thereby realizing the function of adjusting the force acting on the object connected to the support and achieving the effect of vertical and horizontal vibration reduction.

[0106] Under the action of the vertical and horizontal variable periodic reciprocating impact forces W1 and F1 acting on the controlled movable outer retaining ring 2 and the support member 1 under the support, the vertical and horizontal displacements generated by the automatic adjustment of the support upper support member 9 and the external connection body are within a controllable range, realizing the elastic, shear movement and reset of the support connection object, thereby achieving the effect of limiting displacement.

[0107] The present invention effectively reduces the outer radius of the support, and establishes an arc-shaped truncated conical coil spring and a horizontal arc-shaped truncated conical coil spring assembly 4 for the circular support using a truncated conical coil spring. The horizontal arc-shaped truncated conical coil spring assembly 4 fully utilizes the shape and performance parameters of the horizontal arc-shaped truncated conical coil spring. Each horizontal arc-shaped truncated conical coil spring in the horizontal arc-shaped truncated conical coil spring assembly 4 can be completely compressed when an external force acts. After the horizontal arc-shaped truncated conical coil springs in all directions are completely compressed, the spring coils fall on the inner surface of the large coil end clamp 11 of the arc-shaped horizontal conical spring, thereby achieving the maximum space utilization rate of the horizontal arc-shaped truncated conical coil spring assembly 4.

[0108] The horizontal arc-shaped truncated cone coil spring assembly 4 has the combined effect of each horizontal arc-shaped truncated cone coil spring, has greater horizontal elasticity and shear force, has greater horizontal stiffness and vertical stiffness, makes the horizontal elasticity and vertical shear force performance of the support more stable, increases the stability of the horizontal elastic deformation, vertical shear deformation, and reset of the support's horizontal displacement and horizontal displacement reset, vertical displacement and vertical displacement reset, and the force and displacement of the horizontal arc-shaped truncated cone coil spring assembly 4 have omnidirectional performance.

[0109] Fully utilize the vertical downward supporting disc spring 5 and the vertical upward supporting disc spring 7, which have high stiffness and strong buffering and vibration absorption capabilities, and can withstand large loads with small deformation, which is suitable for the characteristics of small vertical space requirements and high stability of the support; fully utilize the vertical downward supporting disc spring 5 and the vertical upward supporting disc spring 7 with variable stiffness, select the ratio of the deformation h0 and thickness t of the disc spring, and obtain different characteristic curves, such as: linear, increasing, decreasing or combined, so that the support has a very wide range of nonlinear characteristics, which can adapt to and adjust different external vibration characteristics requirements; the vertical downward supporting disc spring 5 and the vertical upward supporting disc spring 7 in the support can adopt a combination of overlapping and matching methods to meet the requirements of increased bearing capacity and increased deformation, and convert the kinetic energy generated by vibration into elastic deformation energy. In the process of storing and releasing the elastic deformation energy, the vertical force on the external object connected to the support is reduced, thereby saving the material of the external object and protecting the external object connected by the support, thereby achieving the effect of saving the material of the external object and protecting the external object connected by the support.

[0110] The present invention can control the external force acting on the connected external object after passing through the support to be a constant value, and filter the waveform of the external force through the friction force and horizontal elastic force generated by the support, thereby protecting the external object connected to the support from vertical and horizontal forces within an allowable value range.

[0111] The present invention adjusts the damping coefficient of the support by adjusting the parameters of the components in the support, thereby obtaining an appropriate range of the damping coefficient when the support interacts with the connected object;

[0112] The eight components, namely the horizontal arc-shaped truncated cone coil spring assembly 4, the horizontal conical spring large circle end clamp 11, the horizontal conical spring small circle end clamp 12, the horizontal supporting arc-shaped truncated cone coil spring assembly and the middle clamp 6 of the vertical supporting disc spring, the vertical upward supporting disc spring 7, the upper vertical conical spring 19, the vertical downward supporting disc spring 5, and the vertical conical spring 18, constitute a comprehensive core body of elastic deformation in any direction located in the middle of the friction displacement resettable support. After the friction displacement resettable support adopts high-strength rust-proof metal material, it is a type of fully elastic support, which has the function of elastic recovery after elastic compression and elongation deformation in all directions under the action of forces in all directions, and has durability and stability.
