Large-scale goods shelf self-resetting tension-compression type shock isolation and absorption device and method

Abstract

A large-scale goods shelf self-resetting tension-compression type shock isolation and absorption device and method. The device comprises a large goods shelf, the large goods shelf is installed on a floor slab through supporting columns, a plurality of shock isolation and absorption units are arranged between the large goods shelf and the floor slab, and each shock isolation and absorption unit comprises a connecting steel plate and a plurality of floor embedded steel plates which are symmetrically arranged relative to the connecting steel plate, and further comprises a self-resetting tension-compression type damper which is arranged between the connecting steel plate and the floor embedded steel plates, is fixed through a pre-tightening force given by the floor embedded steel plates and isused for limiting and absorbing lateral displacement and shock of the large goods shelf. Good shock isolation and absorption performance can be provided for the large goods shelf, and it is guaranteed that the large goods shelf is not damaged under the action of horizontal earthquakes or vibration. Meanwhile, a viscous-elastic material body and a pre-tightening spring in the self-resetting tension-compression damper can enable the self-resetting tension-compression damper to return to the initial state after being subjected to horizontal earthquake action or vibration, so that the stability and functionality of the large goods shelf and the device are guaranteed.

Description

technical field [0001] The invention relates to a large shelf self-resetting tension-compression type shock isolation device and a shock isolation method thereof. Background technique [0002] With the rapid development of the economy, the storage forms in all walks of life are becoming more and more diversified and automated. As one of the most basic storage equipment in the logistics link, large storage shelves are widely used in manufacturing, logistics centers, medicine, commerce, etc. It has a wide range of applications in many industries. [0003] At present, the problem of anti-shock and shock absorption in the shelf field has not been effectively resolved. In the current large-scale shelves, the end plates are usually directly welded under the columns, and then the end plates and the foundation are fixed by anchors, chemical anchors or expansion bolts to limit the position of the shelves, which is a rigid connection support. When an earthquake occurs, the horizonta...

AI Technical Summary

Problems solved by technology

[0003] At present, the problem of anti-shock and shock absorption in the field of shelves has not been effectively solved

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 movement and destruction of the shelf, causing the goods on the shelf to fall, resulting in security incident

When using forklifts, stackers or other storage and transportation machinery to store goods, earthquakes or vibrations will impact the structure, causing the structure to vibrate, causing damage or even destruction to the shelf members or supports

At the same time, when the earthquake or vibration is over, the location of the storage and transportation machinery and equipment changes randomly, and manual handling is required to restore the shelf to the state before the earthquake, which greatly increases the workload and may cause a series of personal and property safety issues.

[0004] The traditional shock-absorbing device for shelves is too complicated, not only has limited shock-absorbing effect on shelves, but also cannot avoid damage or even damage to shelf components and supports
