Abstract

The invention relates to the technical field of boom engineering control, discloses a hoisting control method and system, and engineering machinery, which solves the problems of too narrow application scenarios of automatic hoisting operations and inaccurate positioning of boom heads. The method includes: obtaining that the boom head of the boom-type construction machinery reaches the target position of the designated hoisting operation; controlling the boom head to reach the designated position in the process of reaching the target position at a preset speed, and detecting the rotational angular velocity of the boom head , luffing speed, stop slipping angle, and stop slipping luffing range; And the amplitude of the stop slippage is controlled to stop the boom head at the target position. The embodiment of the present invention is applicable to the automatic hoisting operation of boom type engineering equipment.

Description

technical field [0001] The invention relates to the technical field of boom engineering control, in particular to a hoisting control method and system, and engineering machinery. Background technique [0002] As a kind of lifting and handling equipment, crane is widely used in construction industry, manufacturing industry and port transportation industry. [0003] During the traditional hoisting operation, it is difficult for the operator to observe the lifting point and the target position due to the limited field of vision in the cab. Generally, the hoisting command personnel are required to observe the position of the boom head on the spot, and command the operator to operate the boom head to complete the work. . This process relies on manual judgment and communication for many times, and it usually requires repeated adjustments to allow the boom head to reach the target position. For certain dangerous lifting tasks, the command personnel cannot approach the target posi...
