Safe distance control system of hoisting equipment

Abstract

The invention discloses a safe distance control system of hoisting equipment. The system comprises a master control device and multiple measuring devices. The measuring devices are used for being arranged on a lazy arm of the hoisting equipment and a hoisted object correspondingly. The master control device is connected with the multiple measuring devices in a wireless communication manner. The measuring devices are used for detecting the distance and electric field intensity around the measuring devices and transmitting the detected distance and electric field intensity to the master control device. A processing module of the master control device judges the distance and electric field intensity. When the distance is smaller than a preset distance threshold value or the electric field intensity is larger than a preset field intensity threshold value, it is indicated that the distance between the lazy arm of the hoisting equipment or the hoisted object and a surrounding object or high-voltage electrification equipment has reached dangerous distance, an emergency stop control signal is output at this moment, the hoisting equipment stops continuous running in the dangerous direction in time according to the emergency stop control signal, and therefore the lazy arm or the hoisted object can be prevented from further approaching to the surrounding object or the high-voltage electrification equipment, and electric shock or collision accidents are avoided.

Description

technical field [0001] The present application relates to the technical field of automatic control, and more particularly, to a safety distance control system for hoisting equipment. Background technique [0002] When construction personnel carry out electrical installation and construction in substations, power plants and other places, there are high-voltage power lines and high-voltage live objects around them, which may cause major safety accidents if they are not careful. Especially for some operations that require the use of lifting equipment, because there are strict regulations on the safety distance in these places, and at present, the distance between the boom, the hanging object and the electrical equipment can only be measured by visual or rope measurement. Judgment, the error is large, it may cause accidents such as electric shock or collision, and even cause casualties in serious cases. SUMMARY OF THE INVENTION [0003] In view of this, the present applicatio...

[0002] When construction workers are carrying out electrical installation in substations, power plants and other places, there are high-voltage power lines and high-voltage electrified bodies around them, which may cause major safety accidents if they are not careful

Especially for some situations that require the use of lifting equipment for operations, due to the strict regulations on the safety distance of these places, at present, the distance between the boom, the hanging object and the electrical equipment can only be checked by visual or rope measurement. Judgment, the error is large, it may cause accidents such as electric shock or collision, and even cause casualties in severe cases
