Safety control method and system for hoisting equipment

Abstract

The invention provides a safety control method and system for hoisting equipment, and belongs to the technical field of engineering machinery. The method comprises the steps that the hoisting operation stage of hoisting equipment is determined, and the target moving direction of a balance weight in the hoisting operation stage is selected; hoisting operation in the hoisting operation stage is executed, and continuous counterweight movement in the target direction is executed; obtaining a counterweight parameter corresponding to the counterweight movement and a hoisting parameter corresponding to the hoisting operation; and determining whether to execute safety control of the hoisting operation and / or determining whether to execute existing safety control release of the hoisting operation according to the matching degree of the increment size of the counterweight parameter and the increment size of the hoisting parameter. The method is used for safety control of the hoisting equipment.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a safety control method for lifting equipment, a safety control system for lifting equipment, an electronic device, an engineering machinery and a computer-readable storage medium. Background technique [0002] At present, for cranes, including truck cranes, all-terrain cranes, crawler cranes, etc., during the hoisting process, the fixed counterweight is inconvenient to use, and it is increasingly difficult to meet the various hoisting requirements for hoisting operations. In order to improve the use efficiency of the counterweight, improve the hoisting capacity, and reduce the cost of counterweight transportation and installation, it is considered to improve the traditional fixed counterweight into a variable stroke forward and backward movable counterweight. [0003] The mobile counterweight can change the position of the counterweight in real time according to th...

Problems solved by technology

Compared with the fixed counterweight, the mobile counterweight can expand the hoisting capacity of the crane under the same counterweight size, and can flexibly adjust the position of the counterweight to keep the center of gravity of the system always within the range of the slewing support to improve the hoisting stability; however, in In the actual hoisting operation, there are complex operating characteristics. The hoisting weight or moment is not constant in the hoisting operation. It is actually difficult for the mobile counterweight to maintain the balance of the lifting equipment and maintain the balance state. If the balance is not maintained in the operation, there will be safety risks. Therefore, the implementation of the above-mentioned market demand scheme must be based on a reasonable and efficient control strategy, and a balanced safety control strategy can provide personnel, equipment, and hoisting operations. security
