Autoamtic monitor method and device for safety of mining headframe

Abstract

A method and device for monitoring the safety of mining headframe is disclosed. A measuring plate is arranged on the headframe. A shift sensor on gravity pendulum is used to measure the relative shift between the said measuring plate and sensor. The measured signal is processed by circuits and then sent to lower-position unit. The upper-position and lower-position units are communicated with each other via telephone line. The actual shift value is calculated by upper-position unit for displaying, storing, or printing. If the value is higher than a threshold, an alarm signal is autoamtic generated.

Description

technical field [0001] The invention relates to a method and a device for automatically monitoring the safety of a mine head frame. Background technique [0002] Mine headframe is one of the most important equipment in mine production. It is responsible for the important task of lifting ore and transporting production personnel, and its safety and reliability have always been the focus of attention. Once an accident occurs on the derrick, the consequences will be extremely serious, not only causing heavy losses to national property, but also causing heavy casualties. At the same time, derrick safety accidents will also lead to the shutdown of mines, which not only cause heavy economic losses, but also have extremely bad social impacts. [0003] At present, the geometric observation method is adopted for the safety monitoring of the mine derrick at home and abroad, that is, to select several reference points, and to regularly observe the inclination of the derrick and the l...

Problems solved by technology

However, this regular observation method monitors once every few months. In most cases, the regular measurement once every few months cannot reflect the inclination of the derrick and sky wheel in time, and the effect of preventing accidents is not obvious.

Moreover, the measurement datum points of geometric observation are difficult to select and establish, which seriously affects the popularization and use of geometric observation methods in mines.
