Safety monitoring device of bridge type crane trolley

Abstract

The invention relates to a safety monitoring device of a bridge type crane trolley, which comprises a main controller, an encoder, a main hook weight sensor and an auxiliary hook weight sensor, wherein the encoder is used for converting the position information of a main hook, an auxiliary hook, a trolley and a cart into the number of pulses, and the frequencies of the pulses correspond to the movement velocities of the main hook, the auxiliary hook, the trolley and the cart; the pulse signal output end of the encoder is connected with a logic device to be connected to the main controller, and level signals corresponding to trolley operating signals are accessed to the logic device; the main hook sensor and the auxiliary hook sensor are connected with the main controller through an analog channel; the main controller displays the acquired parameter information on a liquid crystal display and stores the acquired parameter information into a memory, and simultaneously, the parameter information is sent to a remote server monitoring center through a wireless connection module; and the main controller compares the acquired parameter information with the preset parameters, and when the detection parameter is abnormal, a control output module outputs corresponding information to the crane trolley.

Description

technical field [0001] The invention relates to an embedded safety monitoring device, in particular to a bridge crane driving safety monitoring device. Background technique [0002] Hoisting crane is a hoisting device used to lift objects and make them move horizontally within a short distance, and is widely used in industrial and mining enterprises. It plays an important role in reducing the labor intensity of workers, improving production efficiency, and promoting the mechanization of the production process. It is one of the indispensable tools in modern production. However, hoisting cranes are special equipment with high risk, and the frequency of accidents is relatively high. At home and abroad, a large number of property losses and personal injury accidents are caused by lifting equipment and lifting operations every year. According to statistics, the death toll of lifting injury accidents ranks first in the death toll of various mechanical accidents in the country. I...
