This invention proposes a novel steel structure seismic-resistant block, fixedly installed at the bottom of a steel box girder and on the inner side of the pier support. It includes a damping plate and a stiffening plate. The damping plate is fixedly mounted on a fixed frame composed of stiffening plates, facing the pier support. The fixed frame is fixedly mounted at the bottom of the steel box girder. The damping plate includes a plate bearing and evenly distributed nails on the plate bearing. Both the plate bearing and the nails are made of neoprene rubber. This invention achieves its damping function by using a neoprene rubber damping plate instead of the original elastic structure. It serves as a primary energy-dissipating structure, with a stiffening plate behind the damping plate acting as a secondary energy-dissipating structure. This multi-layered energy-dissipating structure results in better overall damping performance, effectively absorbing and attenuating vibrations, and reducing the impact of lateral slippage of the superstructure on the pier.

The utility model discloses a vertical filter feeder pipe damping device, including the air inlet pipe of setting in the feeder pipe and being close to the feed valve, air inlet pipe one end is connected the feeder pipe, the other end sealed connection U -shaped pipe, U -shaped pipe free open end is exposed to the washing liquid liquid level above the washing liquid tank, and the curved lower section is soaked in the washing liquid and is provided with micropore, is equipped with the one-way valve of being close to U -shaped pipe and the normally open valve of being close to the feeder pipe on the air inlet pipe. After feeding is completed, the feeder pipe forms vacuum, and the one-way valve opens, and air is rapidly entered through U -shaped pipe and eliminates vacuum, and simultaneously drives a small amount of washing liquid to clean the pipeline, and after air pressure balance, the washing liquid is supplemented automatically through the micropore. The device has small air flow resistance, stable cleaning, convenient maintenance, effectively prolongs the service life of equipment, and has strong adaptability.

A vibration-controlled elastic bearing with steel spring laminated rubber sheet is provided, comprising an upper connecting plate, a lower connecting plate, and a damping body. Multiple vertically arranged damping springs for absorbing vibration energy are evenly distributed inside the damping body. The upper and lower ends of the damping springs, which penetrate the damping body, are respectively connected to the upper and lower connecting plates via an upper sealing plate located above the damping body and a lower sealing plate located on the lower end face of the damping body. This invention optimizes the internal structure of the elastic bearing to achieve dual vibration control, ensuring reliable damping while improving the load-bearing capacity for large shear forces. It solves the pollution problem associated with traditional core rubber seismic isolation bearings. While the damping springs bear the main dynamic load, it reduces fatigue damage to the damping body, lowers its aging rate, and extends its service life.

The invention discloses a storage device and a transport vehicle. The storage device comprises a mounting frame, a storage box and a damping mechanism. And a mounting cavity is formed in the mounting frame. And the storage box is mounted in the mounting cavity. And the damping mechanism is mounted on the mounting frame. The damping mechanism comprises a mounting assembly, a buffer assembly and a transfer assembly. The buffer assembly and the transfer assembly are both installed on the installation assembly, the buffer assembly comprises at least two mutually-overlapped buffer plate bodies, the transfer assembly makes contact with the buffer plate bodies, the side, away from the buffer assembly, of the transfer assembly abuts against the storage box, and the buffer plate bodies can deform between a first form and a second form. The buffer plate body can deform to the first form when the transmission assembly is subjected to external force and can return to the second form when the external force is removed. The problem that in the prior art, a packaging box for externally packaging precise articles is poor in damping effect is solved.

The utility model discloses a single-station wafer thinning machine, which relates to the field of wafer thinning machines and comprises a top plate, supporting rods are fixedly mounted at four corners of the bottom of the top plate, the bottoms of the supporting rods are fixedly mounted at four corners of the top of a workbench, a fixed table is fixedly mounted in the middle of the top of the workbench, and the fixed table is fixedly mounted at the bottom of the top of the workbench.
