Anti-tipping and fall-preventing loading experiment device for soil-supporting cantilever-shaped objects

Abstract

The invention relates to a loading experiment device for anti-tilting and anti-falling loading experiments on various specific natural or artificial objects such as trees and street lamps and for studying the anchoring performance of the ends of these objects. It consists of an experimental frame, a multi-stage loading system and a safety limit system. Composition, multi-level loading system and safety limit system are set inside the test rack, loaded by the weight of the weight, can accurately control the load, load action position and action direction, high safety, reusable, and reduce the test time. Low cost, the loading process can be manually adjusted, without using electricity, and can be used for large-scale low-cost loading experiments on various types of soil-supported cantilever beams in various fields and occasions.

Description

technical field [0001] The invention relates to a loading experiment device for carrying out anti-tilting and anti-falling loading experiments on various specific natural or artificial objects such as trees and street lamps and studying the anchoring performance of the ends of these objects. Background technique [0002] Soil-supported cantilever beams, whose lower end is supported and anchored in the soil, and the beam body mainly bears lateral loads such as wind loads, which cause it to be easily unstable, tilted or toppled as a whole. Objects with similar mechanical and structural characteristics include trees, Pillar billboards, traffic signs, utility poles, street lamps, flagpoles and many other artificial or natural objects and occasions. In order to study the anti-tilt and anti-stability of these objects, the anchoring performance and mechanical properties of the end, and the interaction between the end and the soil, etc., currently the hoist or jack is mainly used fo...

AI Technical Summary

Problems solved by technology

In order to study the anti-tilt and anti-stability of these objects, the anchoring performance and mechanical properties of the end, and the interaction between the end and the soil, etc., currently the hoist or jack is mainly used for loading experiments, and it must be equipped with a very long traction rope and tension gauge. , it is difficult to accurately determine the amount of load applied, the location and direction of the load, and it is difficult to accurately control the loading process. At the same time, it is difficult to prevent the collapse and damage of the experimental object after it is dumped, and it is easy to crush the experimental personnel and experimental equipment, which poses a safety risk. Conduct large-scale low-cost precise loading experiments
