A system and method for recommending working conditions of crane spanning obstacles

Abstract

The invention discloses a recommended system and method for a crane crossing obstacles hoisting condition which comprises a controller and an electrically connected sensor unit, a sound and light alarm device and a display; the sensor unit is composed of a plurality of length sensors and angle sensors installed on the beam of the obstacle hoisting equipment. A recommended human-computer interaction function module, an crossing obstacles hoisting mathematical model calculation function module, a performance table query function module, a recommended condition display function module and a crossing obstacles hoisting warning function module which are added in the system for the crossing obstacles hoisting condition jointly implement the recommended system function for the crane crossing obstacles hoisting condition. A condition information which meet the hoisting requirement will be given according to some information of obstacles, hoisting subjects and through the calculation of the mathematical mode in the crossing obstacles hoisting system, and an alarm will indicate when the hoisting action is approaching the obstacles. The recommended system and method for the crane crossing obstacles hoisting condition reduces the manual calculation and the labor intensity, and improves the work efficiency and safety, and effectively solves the shortcomings of existing technology.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a system and method for recommending working conditions for hoisting across obstacles for a crane. Background technique [0002] Crane obstacle hoisting equipment is mainly used for mobile cranes, such as truck cranes, all-terrain cranes, off-road tire cranes, crawler cranes, etc. They have one common feature: the working range can be changed by changing the length / angle of the jib, and the rated lifting capacity also changes with the change. Nowadays, all kinds of cranes have been widely used in urban construction, factory equipment hoisting, bridge construction and other occasions. The hoisting environment of the crane is relatively complicated, and there may be high-voltage lines, walls, etc. nearby, and hoisting operations across obstacles often occur. [0003] For the hoisting operation across obstacles, it is often necessary for the operator to estimate the length of the...

AI Technical Summary

Problems solved by technology

[0004] At present, the calculation of the working conditions of cross-obstacle hoisting mainly depends on the manual calculation or estimation of the operator, which is closely related to the operator's experience and mathematical calculation ability. Compare the working conditions with the performance table to verify whether the hoisting requirements are met, calculation errors are prone to occur, and the reliability is low; secondly, manually calculate or estimate the required working conditions, manually consult and compare the performance table according to the working conditions, and verify whether it meets the requirements. Hoisting requirements, time-consuming and low work efficiency; finally, in the process of cross-obstacle hoisting, hoisting operations and preventing collisions with obstacles must be considered at the same time, which requires high requirements for operators and low operating safety
