Description

Technical Field

[0001] This utility model relates to the field of accumulator technology, specifically to a vibration-damping accumulator for a walking beam furnace hydraulic pipeline. Background Technology

[0002] Hydraulic piping in a walking beam furnace refers to the piping system that transmits the working fluid in the walking beam furnace hydraulic system. The walking beam furnace hydraulic system is typically used to control various actions of the walking beam furnace, such as lifting and moving, and the hydraulic piping is a key component that enables these actions. A hydraulic accumulator is an energy storage device in a hydraulic-pneumatic system. It converts the energy in the system into compressed energy or potential energy at appropriate times and stores it. When the system needs it, it converts the compressed energy or potential energy into hydraulic or pneumatic energy and releases it to replenish the system. When the system pressure increases instantaneously, it can absorb this energy to ensure that the pressure of the entire system is normal, thereby achieving the effect of vibration reduction and anti-vibration. However, most common accumulators are spring-type and air-bag-type, and their internal energy storage structure is relatively simple. Furthermore, the internal structure of the accumulator is not convenient to install or remove, which reduces the work efficiency of workers in subsequent inspection and maintenance.

[0018] Reference Figures 1 to 5 As shown, this utility model provides a vibration-damping accumulator for a walking beam furnace hydraulic pipeline, comprising: a cylinder 2, with a main cap 1 fixedly connected to the first end of the cylinder 2 and a secondary cap 13 fixedly connected to the tail end of the cylinder 2. A limiting groove is symmetrically opened on the end face of the tail end of the cylinder 2, and an auxiliary cylinder 11 is slidably connected to the tail end of the inner cavity of the cylinder 2. A limiting block 12 is connected to the outer side of the auxiliary cylinder 11 relative to the position of the limiting groove. At the same time, a positioning plate 9 is fixedly connected to the end of the auxiliary cylinder 11 away from the limiting block 12. An airbag assembly 10 is fixedly connected to the side of the positioning plate 9 close to the inner cavity of the auxiliary cylinder 11. One end of a main spring 7 is fixedly connected to the other side of the positioning plate 9, and the other end of the main spring 7 is fixedly connected to the surface of a secondary buffer plate 6. A sealing layer 5 is fixedly connected to the fitting groove 14 opened on the side of the secondary buffer plate 6 through the main buffer plate 3.

[0019] In this embodiment, when the pressure of the hydraulic oil in the walking beam furnace hydraulic pipeline fluctuates, the hydraulic oil in the pipeline flows into the cylinder 2 through the pipe. The hydraulic oil inside the cylinder 2 pushes the buffer assembly, composed of the main buffer plate 3, the sealing layer 5, and the secondary buffer plate 6, to move synchronously. During the movement, the buffer assembly compresses the main spring 7, and the space between the buffer assembly and the positioning plate 9 decreases, allowing other air to flow into the airbag assembly 10 through the inner cavity of the limiting cylinder 8. Subsequently, the airflow is compressed, and the airbag assembly 10 is expanded and deformed by the airflow, thereby enabling the accumulator to move within the walking beam furnace hydraulic pipeline. When the instantaneous pressure increases, it can successfully absorb this energy to ensure the normal pressure of the entire walking beam furnace hydraulic pipeline system, thereby achieving the effect of vibration reduction and anti-vibration. When the accumulator needs to be inspected or maintained, the secondary cover 13 is first removed, and the positioning plate 9, airbag assembly 10, main spring 7 and buffer assembly and other components can be taken out simultaneously through the auxiliary cylinder 11, which improves the efficiency of workers during inspection or maintenance. In addition, the setting of multiple energy storage structures means that when a single energy storage structure is damaged, the accumulator can also have a certain energy storage effect, thereby enhancing the fault tolerance and stability of the accumulator during use.

[0020] As a preferred embodiment, the cylinder 2 has a cylindrical structure. Multiple sets of limiting grooves are opened at equal intervals around the end face of the tail end of the cylinder 2, and all sets of limiting grooves have a square structure. At the same time, the size of the limiting block 12 and the limiting groove are matched, and the end face of the limiting block 12 abuts against the inner surface of the sub-cap 13.

[0021] In this embodiment, as Figure 1 , Figure 3 and Figure 4 The size of the limiting block 12 and the limiting groove are matched, which helps to enhance the stability of the auxiliary cylinder 11 after it is installed inside the cylinder 2.

[0022] In a preferred embodiment, the auxiliary cylinder 11 has a cylindrical structure, the dimensions of the outer side of the auxiliary cylinder 11 are adapted to the dimensions of the inner cavity of the cylinder 2, and the multiple sets of limiting blocks 12 fixedly connected to the outer arc surface of the auxiliary cylinder 11 are all square structures, while the end face of the auxiliary cylinder 11 and the end face of the limiting block 12 are in the same plane.

[0023] In this embodiment, as Figure 1 , Figure 3 and Figure 4 The dimensions of the outer side of the auxiliary cylinder 11 are matched with the dimensions of the inner cavity of the cylinder 2, which can help enhance the sealing at the connection between the auxiliary cylinder 11 and the cylinder 2, and also help enhance the stability of the auxiliary cylinder 11 after it is installed inside the cylinder 2. At the same time, the end faces of the auxiliary cylinder 11 and the limiting block 12 are coplanar, which can help enhance the fixing effect of the secondary cover 13 on the auxiliary cylinder 11.

[0024] In a preferred embodiment, the positioning plate 9 has a circular structure, the size of the outer side of the positioning plate 9 is adapted to the size of the inner cavity of the cylinder 2, and a through-hole is opened in the middle of the positioning plate 9. The through-hole has a circular structure. Meanwhile, the airbag assembly 10 is composed of an airbag layer and a sealing element. The sealing element has a ring structure. The airbag layer is fixedly connected to the surface of the positioning plate 9 through the sealing element, and the inner cavity of the airbag layer is connected to the through-hole.

[0025] In this embodiment, as Figure 1 and Figure 3 The opening of the through-hole allows the gas inside the cylinder 2 to flow with the movement of the buffer component. At the same time, the setting of the airbag component 10 allows the flowing gas to be compressed accordingly and expand the airbag layer, thereby helping to enhance the overall energy storage effect of the accumulator.

[0026] In a preferred embodiment, the positioning plate 9 is fixedly connected to the limiting cylinder 8 on the side away from the airbag assembly 10. The limiting cylinder 8 has a cylindrical structure, and the inner cavity of the limiting cylinder 8 is connected to the through-hole. At the same time, the main spring 7 is sleeved on the outer side of the limiting cylinder 8.

[0027] In this embodiment, as Figure 1The setting of the limiting cylinder 8 can effectively limit the movement range of the buffer component, thereby preventing the main spring 7 from being excessively squeezed by the buffer component and reducing the probability of damage to the main spring 7.

[0028] In a preferred embodiment, the secondary buffer plate 6 has a cylindrical structure, the fitting groove 14 on the arc surface of the secondary buffer plate 6 has a circular structure, and four sets of positioning grooves are equally spaced around the side of the secondary buffer plate 6 away from the main spring 7. The four sets of positioning grooves are distributed in a cross shape, and the main buffer plate 3 is fixedly connected to the surface of the secondary buffer plate 6 by bolts.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 5 The dimensions of the positioning groove and the positioning block 4 are matched, which can help enhance the stability of the fixed connection between the main buffer plate 3 and the secondary buffer plate 6, and also help improve the convenience of installing and removing the sealing layer 5.

[0030] In a preferred embodiment, the main buffer plate 3 has a circular structure, and the positioning blocks 4 are connected to the position of the main buffer plate 3 relative to the positioning groove. The four sets of positioning blocks 4 all have a rectangular structure, and the sealing layer 5 clamped and fixed between the main buffer plate 3 and the secondary buffer plate 6 has an annular structure. The size of the outer side of the sealing ring is adapted to the size of the inner cavity of the cylinder 2. At the same time, the axial section of the sealing ring has a convex structure, and the protruding part of the inner side of the sealing ring is fixedly connected to the fitting groove 14 opened in the secondary buffer plate 6.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 5 The two ends of the inner side of the sealing layer 5 are respectively attached to the outer sides of the main buffer plate 3 and the auxiliary buffer plate 6, while the outer side of the sealing layer 5 is attached to the inner side of the cylinder 2. This can help enhance the sealing of the connection between the buffer assembly and the cylinder 2, ensuring that the hydraulic oil in the walking beam furnace hydraulic pipeline can smoothly push the buffer assembly to move when the pressure fluctuates, thereby ensuring that the excess energy can be absorbed by the accumulator and ensuring the stability of the overall pressure.
