[0021] Embodiment

[0022] Please refer to Figs. 1-2 The utility model provides a technical scheme:

[0023] A paper machine closed gas cover with anti-seismic design, the main body 1 upper end is equipped with a plurality of bolt holes 2, the bolt hole 2 penetrates the main body 1, the main body 1 is equipped with connecting rod 3, the main body 1 bottom is equipped with rubber damping pad 12, the connecting rod 3 below is connected hydraulic damper 4, the hydraulic damper 4 top is equipped with connecting ball head 5, and connecting ball head 5 connects connecting rod 3, the connecting ball head 5 bottom is equipped with driving shaft 6, the driving shaft 6 middle end outside is equipped with damping pressure piece 7, the driving shaft 6 bottom is equipped with hydraulic pressure piece 8, the hydraulic damper 4 bottom is equipped with transmission device 9, the transmission device 9 bottom is equipped with spring 10, the spring 10 bottom is equipped with vibration sensor 11.

[0024] The gas cover body is fixed to the support structure through the bolt holes at the top. The bolt holes run through the body and provide a stable connection for the gas cover installation. Inside the body, a connecting rod is provided, which connects the body to the hydraulic damper. The design of the bolt holes and the connecting rod ensures the strength and stability of the gas cover and effectively transmits external vibrations to the hydraulic damper. The lower end of the hydraulic damper is connected to the transmission device, which is further connected to the vibration sensor through the spring. The drive shaft inside the hydraulic damper is connected to the connecting ball head, and the outer end of the middle of the drive shaft is equipped with a shock-absorbing pad and a hydraulic pad. The shock-absorbing pad and the hydraulic pad cooperate with each other inside the hydraulic damper to absorb vibration energy and reduce the impact of vibration on the equipment. A rubber shock pad is provided at the bottom of the gas cover, which serves as the last buffer barrier to further reduce the transmission of vibration and ensure that the connection between the equipment and the ground is not affected by excessive vibration.

[0025] During normal operation of the papermaking machine, the high-speed operation of mechanical components can generate vibrations, especially when under high load, frequent start-up of equipment, or when a fault occurs, the vibration amplitude is larger. If these vibration energies are not controlled, they will be directly transmitted to the gas cover body and other connected components, which may cause equipment failure or damage. When external vibrations are transmitted to the gas cover, the vibrations are first transmitted to the connecting rod inside the gas cover body. The connecting rod acts as a load-bearing vibration and transmits vibration energy to the hydraulic damper. Inside the hydraulic damper, vibration energy begins to be absorbed and consumed. Inside the hydraulic damper, a shock-absorbing pad and a hydraulic pad are provided. When the vibration enters the hydraulic damper, the shock-absorbing pad and the hydraulic pad absorb vibration energy through physical and hydraulic action, respectively. The shock-absorbing pad first buffers the vibration by elastic deformation, and the hydraulic pad further consumes vibration energy by generating resistance through the flow of hydraulic oil. The hydraulic pad and the shock-absorbing pad cooperate to reduce the vibration amplitude. When the hydraulic damper absorbs part of the vibration energy, the remaining energy is transmitted to the spring through the transmission device. The spring further absorbs and buffers the remaining vibration energy by deforming. The spring converts the energy into elastic potential energy, reducing the transmission of vibration in the equipment. Finally, the vibration energy is effectively dispersed and consumed after being absorbed by the spring. A vibration sensor is provided at the bottom of the spring. When the vibration exceeds the preset threshold, the vibration sensor will feed back the monitored data to the control system in real time. The control system automatically adjusts the working state of the hydraulic damper or sends a warning signal to the operator according to the vibration intensity data fed back by the sensor, prompting the operator to take measures. Through this real-time monitoring and automatic response system, the equipment can adjust the working state in time to avoid irreversible damage to the equipment caused by excessive vibration. The rubber shock pad provided at the bottom of the equipment serves as the final buffer barrier to prevent the remaining vibration from being transmitted to the ground or foundation platform through the bottom of the equipment. The rubber shock pad absorbs small vibrations by its elastic deformation and effectively reduces the transmission of vibration between the ground and the equipment, further enhancing the anti-vibration capability of the equipment.
