Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of shock absorption, and in particular relates to a three-way viscous damper. Background Art
[0002] A three-way viscous damper is a specially designed damper that can provide damping force in three directions (usually two horizontal directions and one vertical direction). This type of damper is widely used in building structures, bridges, industrial equipment, etc. to reduce vibration, control displacement and improve the seismic performance of the structure. The working principle of a three-way viscous damper is based on the flow characteristics of a viscous fluid. When the piston inside the damper moves, the viscous fluid flows through small holes or gaps, generating resistance, thereby consuming energy and providing damping force. At present, one end of the viscous damper is connected to the pipeline, and the other end is connected to a structure such as a steel beam or a floor. When the pipeline vibrates, no matter in which direction the vibration occurs, it will be converted into a relative displacement of the piston and the cylinder. When the displacement occurs, the damping agent is squeezed, thereby reducing the vibration of the pipeline. However, in pipeline management, when installing a three-way viscous damper, it is necessary to use heavy anti-vibration pipe clamps and other accessories on the pipeline. When using accessories such as anti-vibration pipe clamps, the weight of the accessories themselves will generate an additional load burden on the pipeline. If used rashly, there is a risk of damaging the pipeline, and the force on the pipeline needs to be re-evaluated, which increases the workload of pipe vibration management. Therefore, in order to avoid the shortcomings of the prior art, it is necessary to improve the prior art. Utility Model Content
[0003] The purpose of the utility model is to provide a three-way viscous damper, which can adjust the supporting force. When managing the pipeline, the supporting force is adjusted to support accessories such as anti-vibration pipe clamps, so as to prevent the weight of accessories such as anti-vibration pipe clamps from generating additional load burden on the pipeline, thereby avoiding the hidden danger of pipeline damage.
[0004] In order to solve the above technical problems, the technical solutions adopted by the utility model are as follows:
[0005] A three-way viscous damper comprises an upper connecting plate, a lower connecting plate, a load adjustment ring and a setting spring, wherein the upper connecting plate is connected to a piston, the lower connecting plate is connected to a cylinder body, the piston is inserted into the cylinder body, a damping agent is filled between the piston and the cylinder body, the load adjustment ring is connected to the outer side of the cylinder body so as to be adjustable up and down, the setting spring is sleeved on the outer side of the cylinder body, one end of the setting spring abuts against the upper connecting plate, and the other end abuts against the load adjustment ring.
[0006] As a preferred solution of the above-mentioned three-way viscous damper, the scale is connected to the side surface of the upper connecting plate, the scale and the axis of the setting spring are parallel to each other, and the scale extends downward.
[0007] As a preferred solution of the above three-way viscous damper, the outer side of the cylinder body is provided with threads, and the load adjustment ring body is connected to the outer side of the cylinder body with threads.
[0008] As a preferred solution of the above three-way viscous damper, a pointer extending outward is provided on the load adjustment ring, and the pointer points to the scale for easy reading.
[0009] As a preferred solution of the above three-way viscous damper, the scale is connected to the side surface of the upper connecting plate, and the scale extends downward.
[0010] As a preferred solution of the above three-way viscous damper, the upper connecting plate and the lower connecting plate are respectively provided with a plurality of mounting holes.
[0011] As a preferred solution of the above-mentioned three-way viscous damper, a polytetrafluoroethylene plate for reducing friction is provided at the abutment point between the setting spring and the upper connecting plate.
[0012] The three-way viscous damper provided by the present invention has the following beneficial effects compared with the prior art:
[0013] The utility model can adjust the supporting force. When the pipeline is managed, the supporting force is adjusted to support accessories such as anti-vibration pipe clamps. When in use, the upper connecting plate is connected to accessories such as anti-vibration pipe clamps, and the anti-vibration pipe clamp is sleeved on the pipeline. When the pipeline vibrates, the upper connecting plate is driven to move by the anti-vibration pipe clamp, so that the piston moves. Since the piston is inserted into the cylinder body, and a damping agent is filled and arranged between the piston and the cylinder body, the movement of the piston will squeeze the damping agent to generate resistance, which has the effect of slowing down the movement of the piston and achieving vibration reduction of the pipeline. Since the piston is smaller than the diameter of the cylinder body, there is enough space between the piston and the cylinder body to fill the damping agent. Therefore, when the piston and the cylinder body are relatively dislocated, the damping agent will be squeezed to reduce the vibration. Since the anti-vibration pipe clamp needs to be sleeved on the pipeline, the weight of the anti-vibration pipe clamp itself will increase the load burden on the pipeline, which has the hidden danger of damage to the pipeline. The load adjustment ring in the utility model can move up and down It is connected to the outer side of the cylinder body, and one end of the setting spring is abutted against the upper connecting plate, and the other end is abutted against the load adjustment ring. Therefore, adjusting the load adjustment ring upwards can compress the setting spring, so that the setting spring provides an upward supporting force to support the anti-vibration pipe clamp in a compressed state, so that the self-weight of the anti-vibration pipe clamp will not be applied to the pipeline, and the self-weight of accessories such as the anti-vibration pipe clamp will not generate additional load burden on the pipeline. According to the gravity of accessories such as the anti-vibration pipe clamp and the elastic coefficient of the setting spring, the distance that the setting spring needs to be compressed is calculated, so that the supporting force provided by the elastic force generated after the setting spring is compressed is equal to the gravity of accessories such as the anti-vibration pipe clamp, so that the supporting force provided by the setting spring and the gravity of accessories such as the anti-vibration pipe clamp are just offset, so as to prevent the self-weight of accessories such as the anti-vibration pipe clamp from generating additional load burden on the pipeline, avoid the hidden danger of pipeline damage, and do not need to re-evaluate the force on the pipeline, thereby reducing the workload of pipe vibration management.

[0025] Please also read Figures 1 to 4 Now, the three-way viscous damper provided in the embodiment of the utility model is described.
[0026] like Figures 1 to 4As shown, the three-way viscous damper of the utility model comprises an upper connecting plate 100, a lower connecting plate 200, a load adjustment ring 300 and a setting spring 400, wherein the upper connecting plate 100 is connected with a piston 110, the lower connecting plate 200 is connected with a cylinder 210, the piston 110 is inserted into the cylinder 210, a damping agent is filled between the piston 110 and the cylinder 210, the load adjustment ring 300 is connected to the outer side of the cylinder 210 so as to be adjustable up and down, the setting spring 400 is sleeved on the outer side of the cylinder 210, one end of the setting spring 400 abuts against the upper connecting plate 100, and the other end abuts against the load adjustment ring 300. The load adjustment ring 300 can compress the setting spring 400 and adjust the compression distance of the setting spring 400 by moving up and down on the outside of the cylinder body 210. The elastic force is adjusted by adjusting the compression distance of the setting spring 400, and the elastic force is adjusted to be equal to the gravity of accessories such as the anti-vibration pipe clamp of the pipeline. In this way, the elastic force provided by the setting spring 400 just offsets the gravity of accessories such as the anti-vibration pipe clamp, thereby avoiding the self-weight of accessories such as the anti-vibration pipe clamp to generate additional load burden on the pipeline, thereby preventing the hidden danger of damage to the pipeline. The elastic force provides a supporting force equal to the gravity to accessories such as the anti-vibration pipe clamp, so that there is no need to re-evaluate the force on the pipeline, thereby reducing the workload of pipe vibration management.
[0027] Exemplarily, the scale 500 is connected to the side of the upper connecting plate 100, the scale 500 is parallel to the axis of the setting spring 400, and the scale 500 extends downward. The scale 500 can read the specific compression distance of the setting spring 400. In use, according to the gravity F of accessories such as anti-vibration pipe clamps and the elastic coefficient K of the setting spring 400, the distance S=F / K that the setting spring 400 needs to be compressed is calculated. When the compression distance of the setting spring 400 is S, the supporting force provided by the elastic force of the setting spring 400 is equal to the gravity of accessories such as anti-vibration pipe clamps, thereby avoiding the self-weight of accessories such as anti-vibration pipe clamps to generate additional load burden on the pipeline.
[0028] Exemplarily, the scale 500 is connected to the side of the upper connecting plate 100, and the scale 500 extends downward. It is more convenient and intuitive to install the scale 500 on the side of the upper connecting plate 100 to observe the readings. The scale 500 extends downward and is parallel to the axial direction of the setting spring 400, which makes it convenient to confirm the specific compression distance of the setting spring 400 through the reading of the scale 500.
[0029] Exemplarily, the outer side of the cylinder body 210 is provided with threads, and the load adjustment ring 300 is connected to the outer side of the cylinder body 210 by threads, so that the load adjustment ring 300 can be adjusted up and down through the threads, thereby adjusting the compression distance of the setting spring 400.
[0030] Exemplarily, the load adjustment ring 300 is provided with an outwardly extending pointer, which points to the scale 500 for easy reading. The outwardly extending pointer is provided so that the pointer points to the scale 500, which can facilitate reading of the scale 500 and avoid the influence of reading errors on the specific adjustment position of the load adjustment ring 300.
[0031] Exemplarily, the upper connecting plate 100 and the lower connecting plate 200 are respectively provided with a plurality of mounting holes 600. The upper connecting plate 100 uses bolts through the mounting holes 600 to facilitate the connection of accessories such as anti-vibration pipe clamps to the upper connecting plate 100, and the lower connecting plate 200 uses bolts through the mounting holes 600 to connect to structures such as steel beams or floors.
[0032] Exemplarily, a polytetrafluoroethylene plate for reducing friction is provided at the contact point between the adjustment spring 400 and the upper connecting plate 100, so as to reduce the friction and reduce the influence of the adjustment spring 400 when the upper connecting plate 100 and the lower connecting plate 200 are displaced.
[0033] The three-way viscous damper provided by the present invention has the following beneficial effects compared with the prior art:
[0034] The utility model can adjust the supporting force. When the pipeline is managed, the supporting force is adjusted to support accessories such as the anti-vibration pipe clamp. When in use, the upper connecting plate 100 is connected to accessories such as the anti-vibration pipe clamp, and the anti-vibration pipe clamp is sleeved on the pipeline. When the pipeline vibrates, the upper connecting plate 100 is driven to move by the anti-vibration pipe clamp, thereby moving the piston 110. Since the piston 110 is inserted into the cylinder body 210, and a damping agent is filled between the piston 110 and the cylinder body 210, the movement of the piston 110 will squeeze the damping agent to generate resistance. , which slows down the movement of the piston 110 and reduces the vibration of the pipeline. Since the piston 110 is smaller than the diameter of the cylinder 210, there is enough space between the piston 110 and the cylinder 210 to fill the damping agent. Therefore, when the piston 110 and the cylinder 210 are relatively displaced, the damping agent will be squeezed to reduce the vibration. Since the anti-vibration pipe clamp needs to be sleeved on the pipeline, the weight of the anti-vibration pipe clamp itself will increase the load burden on the pipeline, causing the pipeline to be damaged. In the utility model, the load adjustment ring 30 0 is connected to the outer side of the cylinder body 210 so as to be movable up and down, and one end of the setting spring 400 abuts against the upper connecting plate 100, and the other end abuts against the load adjustment ring 300, so that the setting spring 400 can be compressed by adjusting the load adjustment ring 300 upward, so that the setting spring 400 provides an upward supporting force to support the anti-vibration pipe clamp in a compressed state, so that the self-weight of the anti-vibration pipe clamp will not be applied to the pipeline, and the self-weight of accessories such as the anti-vibration pipe clamp will not generate an additional load burden on the pipeline. The gravity of the accessory and the elastic coefficient of the setting spring 400 are used to calculate the distance that the setting spring 400 needs to be compressed, so that the supporting force provided by the elastic force generated after the setting spring 400 is compressed is equal to the gravity of accessories such as the anti-vibration pipe clamp, so that the supporting force provided by the setting spring 400 and the gravity of accessories such as the anti-vibration pipe clamp are exactly offset, preventing the self-weight of accessories such as the anti-vibration pipe clamp from generating additional load burden on the pipeline, avoiding the hidden danger of pipeline damage, and there is no need to re-evaluate the force on the pipeline, thereby reducing the workload of pipe vibration management.
[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
