High-damping self-limiting shock insulation and absorption device and using method

Abstract

The invention provides a high-damping self-limiting shock insulation and absorption device. The high-damping self-limiting shock insulation and absorption device comprises a shelf bottom force-transfer steel plate, a floor embedded steel plate, pre-tightening bolts, a shock insulation and absorption cushion and a curved steel plate spring, wherein limiting holes are formed in the shelf bottom force-transfer steel plate, and threaded holes are formed in the upper end face of the floor embedded steel plate and correspond to the limiting holes; the pre-tightening bolts penetrate through an installation gap to be connected into the limiting holes and the threaded holes in a threaded manner; locking nuts are mounted at the ends, stretching out of the limiting holes, of the pre-tightening bolts;the curved steel plate spring is fixed between the shelf bottom force-transfer steel plate and the floor embedded steel plate. According to the high-damping self-limiting shock insulation and absorption device, horizontal excitations such as earthquakes applied to a shelf can be isolated and weakened, so that it is guaranteed that the large shelf only slides leftwards and rightwards within a narrow range when vibrated and can return to the original position after the vibration process is completed. The invention further provides a using method of the high-damping self-limiting shock insulation and absorption device.

Description

technical field [0001] The invention belongs to the technical field of vibration isolation and absorption, and in particular relates to a high-damping self-limiting vibration isolation device and a use method. Background technique [0002] Shelves generally refer to shelves for storing goods. Shelves are used to store storage equipment for items. Shelves are an important tool for improving efficiency in modern warehouses. It has not only promoted the development of the local economy, but also brought new management concepts and management technologies. At present, the types of shelves used in enterprise warehouses tend to be more and more automated and intelligent. However, until now, the anti-shock and shock-absorbing problems in the shelf field have not been effectively resolved. For all kinds of large shelves at present, the end plate is directly welded under the column, and then the end plate and the foundation are fixed by anchor bolts, chemical anchors or expansion bo...

AI Technical Summary

Problems solved by technology

However, so far, the problem of anti-shock and shock absorption in the shelf field has not been effectively resolved.

When an earthquake occurs, the horizontal force and vertical force generated by the earthquake are directly transmitted to the support from the bottom column, which can easily cause damage or even destruction of the support, resulting in the destruction of the overall shelf

[0003] In the prior art, in order to solve the seismic problem of the shelf, a more effective method is to install a shock absorbing device on the shelf; however, the traditional shelf shock absorbing device is too complicated, and still needs to use a rigid connection support to support the shelf

When sliding occurs due to earthquakes or vibrations in the horizontal direction, the shelves will slip and cannot be returned, resulting in serious damage to the shelves
