Crane as well as fixed point hoisting control method, equipment and system thereof

Abstract

The invention provides a crane as well as a fixed point hoisting control method, equipment and system thereof. Wherein, the method comprises steps of: under a fixed point hoisting learning model, recording position parameters of a suspension arm and a hoisting mechanism on a hoisting track according to a set time interval; and controlling the next hoisting process according to the recorded position parameters. Due to the recording of the position parameters of each suspension arm and each hoisting mechanism on the hoisting track under the fixed point hoisting learning model, the subsequent hoisting process can be conducted automatically according to the position parameters, so that the commanding intensity of an operator can be lowered, the environment suitability and the humanization of the hoisting equipment can be improved, the problem of operation difficulty as the hoisted object moving track is controlled by a conductor each time in the fixed point hoisting operation process is solved, and the work efficiency is also improved.

Description

technical field [0001] The present invention relates to the field of construction machinery, and more specifically, to a crane and its fixed-point hoisting control method, equipment and system. Background technique [0002] At present, the electronic control system of cranes is more and more widely used, and the technology is more and more mature and reliable. During the hoisting process, the commander usually stands in different directions to observe the relative position of the hoisting object and the obstacle object, and then control the running track of the hoisting object to avoid collisions with other obstacles. [0003] The hoisting operation method of the above-mentioned crane requires the commander to observe the lifting object and the surrounding environment from different positions each time during the fixed-point and fixed-route hoisting process, which increases the workload of the commander. Moreover, when hoisting near some high-altitude obstacles, it is relat...

AI Technical Summary

Problems solved by technology

[0003] The hoisting operation method of the above-mentioned crane requires the commander to observe the lifting object and the surrounding environment from different positions every time during the hoisting process of fixed points and fixed routes, which increases the workload of the commander

Moreover, when hoisting near some high-altitude obstacles, it is relatively difficult for the commander to observe; or the environment is relatively harsh, which is harmful to the commander's body, and it is not suitable for the commander to stay for a long time.

[0004] In view of the above-mentioned fixed-point hoisting operation process, it is difficult to rely on the commander to control the trajectory of the hoisted object every time, and no effective solution has been proposed so far.
