Description

Technical Field

[0001] The utility model relates to the technical field of dampers, in particular to a viscous damper with damping force in the vertical direction. Background Technique

[0002] As a commonly used energy-consuming component, the viscous damper is widely used in energy dissipation and shock absorption projects. The common viscous damper mainly consists of a piston, a piston rod, a cylinder body and a seal, etc. The piston divides the inside of the cylinder body into two chambers, and the two chambers are filled with viscous damping liquid as the damping medium. There are small holes on the piston or there is a gap between the piston and the cylinder body to allow the damping medium to pass through; when the piston and the cylinder body move relative to each other, the piston will squeeze the damping medium in the chamber on one side of its moving direction, and the squeezed damping medium flows to the other chamber through the small holes on the piston or the gap between the piston and the cylinder body. The damping medium converts the mechanical energy transmitted by the structure into heat energy and dissipates it during the high-speed flow process, thereby playing the role of shock absorption, buffering and energy consumption.

[0003] In practical applications, the conventional viscous damper often shows a small damping force in the vertical direction, which to a certain extent limits the full play of its shock absorption effect, and then leads to the problem of insufficient buffering effect. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the conventional viscous damper often shows a small damping force in the vertical direction in the prior art, which to a certain extent limits the full play of its shock absorption effect, and then leads to the problem of insufficient buffering effect, and to propose a viscous damper with damping force in the vertical direction.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a viscous damper with damping force in the vertical direction, including a housing, a plunger is arranged inside the housing, a lower cylinder is arranged at the top of the housing, a connecting plate is horizontally arranged at the top of the lower cylinder, a vertical pipe is arranged at the top of the plunger, and damping liquid is filled inside the housing.

[0006] Preferably, outer end caps are arranged at both ends of the housing, and a rib plate is arranged at the bottom of the housing.

[0007] Preferably, a mounting plate is installed at the bottom of the rib plate, and the mounting plate is arranged below the housing.

[0008] Preferably, an upper cylinder is arranged at the bottom of the connecting plate, and the upper cylinder is connected to the lower cylinder.

[0009] Preferably, a sealing sleeve is sleeved outside the lower cylinder and the upper cylinder.

[0010] Preferably, inner end caps are provided at both ends of the plunger.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0012] In the present utility model, the vibrating pipeline is fixed to the connecting plate through the pipe clip accessory. When the pipeline vibrates, the plunger is driven to vibrate through the vertical pipe. When the plunger vibrates, it will squeeze and stretch the damping liquid. At this time, the damping liquid generates a force in the direction opposite to the vibration direction. At the same time, the squeezed and stretched damping liquid will generate heat and be released to the environment through the housing. In this process of action and reaction, the energy of the pipeline vibration is gradually absorbed by the damping liquid, thereby alleviating the vibration of the pipeline. The plunger is horizontally placed, increasing its contact area with the damping liquid and effectively improving the damping force. Description of the Drawings

[0016] In order to more clearly understand the above objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0017] In the following description, many specific details are set forth to facilitate a thorough understanding of the present utility model. However, the present utility model may be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0018] Embodiment 1: As shown in Figure 1 and Figure 2 The present utility model provides a technical solution: a viscous damper with damping force in the vertical direction, including a housing 1, a plunger 4 is arranged inside the housing 1, a lower cylinder 5 is arranged at the top of the housing 1, a connecting plate 8 is horizontally arranged at the top of the lower cylinder 5, a vertical pipe 9 is arranged at the top of the plunger 4, and a damping liquid 10 is filled inside the housing 1.

[0019] In this embodiment, the vibrating pipeline is fixed to the connecting plate 8 through the pipe clamp attachment. When the pipeline vibrates, the plunger 4 is driven to vibrate by the vertical pipe 9. When the plunger 4 vibrates, it will squeeze and stretch the damping liquid 10. At this time, the damping liquid 10 generates a force in the opposite direction to the vibration direction. At the same time, the damping liquid 10 that is squeezed and stretched will generate heat, which is released into the environment through the housing 1. In this process of action and reaction, the energy of the pipeline vibration is gradually absorbed by the damping liquid 10, thereby alleviating the vibration of the pipeline. The plunger 4 is placed horizontally, increasing its contact area with the damping liquid 10 and providing damping force.

[0020] Embodiment 2: As Figure 1 and Figure 2 shown, outer end caps 2 are provided at both ends of the housing 1. A rib plate 11 is provided at the bottom of the housing 1. An installation plate 12 is installed at the bottom of the rib plate 11. The installation plate 12 is arranged below the housing 1. An upper cylinder 7 is provided at the bottom of the connecting plate 8. The upper cylinder 7 is connected to the lower cylinder 5. A sealing sleeve 6 is sleeved outside the lower cylinder 5 and the upper cylinder 7. Inner end caps 3 are provided at both ends of the plunger 4.

[0021] In this embodiment, the outer end cap 2 prevents external impurities, dust, moisture, etc. from entering the damper interior, ensuring the cleanliness and stability of the damper interior working environment, which helps to extend the service life of the damper and ensure its stable performance. The rib plate 11 can increase the bending and torsional resistance of the installation plate 12, making it not easily deformed or damaged when bearing the force and moment transmitted by the damper, thereby improving the strength and stability of the entire connection structure. At the same time, it helps to evenly disperse the force generated by the damper onto the installation plate 12, avoiding local stress concentration and reducing the risk of structural failure caused by stress concentration. The inner end cap 3 separates the working area inside the damper from other parts, protecting the internal damping medium and working components from external interference and pollution. The lower cylinder 5 and the upper cylinder 7 provide a containment space for the internal working components and damping medium of the damper and protect them from the influence and damage of the external environment. During the operation of the damper, it bears the internal pressure, tensile force, and possible bending stress, ensuring the integrity and stability of the structure. The sealing sleeve 6 can ensure that the damping medium does not leak out from the gap between the cylinder barrel and the piston rod when the piston of the viscous damper moves relative to the cylinder barrel, thereby maintaining the normal working performance of the damper. Good sealing can ensure that the quantity and performance of the damping medium are stable during the long-term use of the damper, enabling the damper to continuously and effectively dissipate vibration energy, playing a role in shock absorption, buffering, and energy dissipation.

[0022] Working principle of this embodiment: During use, first, the vibrating pipeline is fixed to the connecting plate 8 through the pipe clamp accessory. When the pipeline vibrates, the plunger 4 is driven to vibrate by the vertical pipe 9. When the plunger 4 vibrates, it will squeeze and stretch the damping liquid 10. At this time, the damping liquid 10 generates a force in the direction opposite to the vibration direction. At the same time, the damping liquid 10 that is squeezed and stretched will generate heat and be released into the environment through the housing 1. In this process of action and reaction, the vibration energy of the pipeline is gradually absorbed by the damping liquid 10, thereby alleviating the vibration of the pipeline. The plunger 4 is horizontally placed, increasing its contact area with the damping liquid 10 and providing damping force.

[0023] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as the technical solution content of the present invention is not departed from, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
