Abstract
Description
Technical Field
[0001] This utility model relates to the field of viscous damper technology, and in particular to a sliding damping box. Background Technology
[0002] Dampers are general-purpose devices used for industrial vibration reduction. The most common products are hydraulic dampers and viscous dampers, which mainly rely on the viscous force generated by the fluid to reduce vibration. Hydraulic dampers are vibration control devices that are highly responsive to speed. During normal expansion and deformation of pipelines or equipment, they move slowly accordingly, with a relatively small damping force. When the load changes rapidly, they generate a counter-resistance equal to the vibration force, suppressing larger vibrations or displacements in the pipeline or equipment, reducing the amplitude, and thus protecting the pipeline or equipment. Viscous dampers, on the other hand, reduce vibration by using the deformation of the damping fluid to dissipate the vibrational kinetic energy of the pipeline, converting the vibrational kinetic energy into the heat energy of the damping fluid, thereby reducing the adverse effects of vibration on the pipeline.
[0003] However, under normal circumstances, neither of the above two types of damping devices has good support capacity and cannot effectively support the weight load of vibrating equipment. The damper is easily damaged by the weight load of the equipment it supports, resulting in damage to the damper. Moreover, the damping performance of the above two types of dampers is unstable. This is because the viscosity of the damping fluid changes with temperature. Especially in summer when the ambient temperature is high, the viscosity of the damping fluid will decrease, resulting in a poor damping force and an unsatisfactory vibration reduction effect of the damper. Utility Model Content
[0004] To address the technical problems of existing dampers failing to effectively support the weight load of vibrating equipment and the unstable damping performance of dampers leading to unsatisfactory vibration reduction effects, this utility model provides the following technical solution.
[0005] This utility model discloses a sliding damping box, including an upper connecting plate and a box body located below the upper connecting plate. A plunger is fixedly connected to the lower part of the upper connecting plate. The inner cavity of the box body is sealed with a right partition and a left partition arranged opposite to each other. The cavity formed by the right partition, the left partition and the box body is filled with damping fluid. The lower part of the plunger extends into the damping fluid. A right support plate and a left support plate extending into the inner cavity of the box body are fixedly connected to the lower sides of the upper connecting plate. The lower ends of the right support plate and the left support plate respectively abut against a plurality of sliding bodies located at the bottom of the box body.
[0006] As a further technical solution, rubber pads with the same structure are provided on both sides of the right support plate and both sides of the left support plate.
[0007] As a further technical solution, the sliding bodies are all installed in the gap between the two rubber pads.
[0008] As a further technical solution, the plunger has a rectangular cross-sectional shape.
[0009] As a further technical solution, the sliding body is a ball bearing or a sliding roller connected to the housing.
[0010] As a further technical solution, the lengths of the right support plate and the left support plate are less than the length between the two opposing inner walls of the box.
[0011] The beneficial effects of this utility model are as follows: A right support plate and a left support plate are provided opposite to each other at the lower part of the upper connecting plate. Several sliding bodies located at the bottom of the housing are abutted against the lower ends of the right and left support plates, which can bear the weight load of the equipment, achieving free horizontal sliding under heavy load conditions and ensuring the normal operation of the damper. Simultaneously, two rubber pads are provided on both sides of the right and left support plates. When the equipment vibrates, the rubber pads can improve the frictional damping effect on the right and left support plates, enhancing the damping effect of the damper and compensating for the problem of insufficient damping force in high-temperature environments, thus ensuring the vibration reduction effect of the damper.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 and Figure 2 As shown, this utility model discloses a sliding damping box, including an upper connecting plate 1 and a box body 2 located below the upper connecting plate 1. The upper connecting plate 1 is connected to a pipeline or other vibrating equipment via pipe clamps, and the box body 2 is connected to a fixed steel frame. A plunger 7 is fixedly connected to the lower part of the upper connecting plate 1, and the lower part of the plunger 7 extends into the damping fluid 6 for damping and vibration reduction of the pipeline.
[0018] In a preferred embodiment, the inner cavity of the housing 2 is sealed with a right partition 5 and a left partition 9 arranged opposite to each other. The right partition 5 and the left partition 9 are located on both sides of the plunger 7, and their ends are fixedly connected to and sealed to the inner wall of the housing 2. Thus, the right partition 5, the left partition 9, and the housing 2 form a cavity containing damping fluid 6. The lower part of the plunger 7 extends into the damping fluid 6. In this embodiment, the plunger 7 has a square or rectangular cross-sectional shape, and the lower end of the plunger 7 is sealed, preventing the damping fluid 6 from flowing into the plunger 7. This structure increases the viscous damping force of the damping fluid 6 around the plunger 7. When the pipeline vibrates, the vibration causes the upper connecting plate 1 to vibrate. At this time, the plunger 7 vibrates, and the plunger 7 exerts squeezing and shearing forces on the damping fluid 6. The damping fluid 6 forms a reverse viscous damping force on the plunger 7, which can effectively reduce the adverse effects of vibration on the pipeline.
[0019] In a preferred embodiment, a right support plate 4 and a left support plate 10 extending into the inner cavity of the housing 2 are fixedly connected to the lower sides of the upper connecting plate 1. The right support plate 4 and the left support plate 10 are used to support the upper connecting plate 1 and the pipe. The right support plate 4 is located between the right partition 5 and the housing 2, and the left support plate 10 is located between the left partition 9 and the housing 2. The lower ends of the right support plate 4 and the left support plate 10 respectively abut against a plurality of sliding bodies 8 located at the bottom of the housing 2. At this time, the length of the right support plate 4 and the left support plate 10 is less than the length between the two opposite inner walls of the housing 2, that is, the length of the right support plate 4 and the left support plate 10 is less than the length of the right partition 5 and the left partition 9. When the right support plate 4 and the left support plate 10 slide on the upper end of the sliding body 8, they will not collide with the inner wall of the housing 2.
[0020] Both sides of the right support plate 4 and both sides of the left support plate 10 are provided with rubber pads 3 of the same structure. That is, a rubber pad 3 is provided between the side wall of the housing 2 and the right support plate 4, and a rubber pad 3 is provided between the right partition plate 5 and the right support plate 4. The two rubber pads 3 press the right support plate 4 together. Similarly, two rubber pads 3 are provided on both sides of the left support plate 10. At this time, the sliding body 8 is installed in the gap between the two rubber pads 3. The sliding body 8 is a ball or sliding roller connected to the housing 2.
[0021] The working principle of this utility model is as follows: During assembly, each sliding body 8 is installed in the gap between the two rubber pads 3 on both sides of the right support plate 4 and the left support plate 10, with the sliding body 8 located at the bottom of the housing 2. The lower ends of the left support plate 10 and the right support plate 4 are supported on the sliding body 8, and the upper ends of the left support plate 10 and the right support plate 4 are connected to the lower part of the upper connecting plate 1. The left partition plate 9, the right partition plate 5, and the housing 2 form an independent cavity, and damping fluid 6 is injected into the cavity; the plunger 7 is immersed in the damping fluid 6, and the sides of the left support plate 10 and the right support plate 4 are respectively pressed against the sides of the rubber pads 3 on both sides.
[0022] During operation, the pipeline is connected to the upper connecting plate 1 via pipe clamps. The weight load of the pipeline is applied to the left support plate 10 and the right support plate 4 through the upper connecting plate 1, and then to the sliding body 8 through the left support plate 10 and the right support plate 4, thus achieving sliding support through the sliding body 8. At the same time, when the pipeline vibrates, the upper connecting plate 1 will drive the left support plate 10, the right support plate 4 and the plunger 7 to vibrate together. When the left support plate 10 and the right support plate 4 vibrate, they will form friction with the rubber pads 3 on both sides, generating frictional damping force. When the plunger 7 vibrates, it will generate squeezing and shearing force on the damping fluid 6. The damping fluid 6 forms a reverse viscous damping force on the plunger 7. The above frictional damping force and viscous damping force are the damping forces required for pipeline vibration reduction, which can effectively reduce the vibration of the pipeline while reducing the impact of high temperature.
[0023] The preferred embodiments and examples of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
