Problems solved by technology
[0003] In the existing conventional technology, most of the power supply cables of the stacking system are driven by the torrent when the stacking is rotating, and the range of the rotation angle is often limited by the mechanical limit.
This results in a limited rotation angle range of the stacking slewing mechanism, which causes great inconvenience when the stockyard is remodeled or re-planned.
In addition, in the mode of automatic stacking, there are many links of human participation in the conventional control method, and the operation process is not simple

The invention proposes a stockpile swing mechanism control method for a top pile laterally-taking machine of a round stock yard. A stockpile electrical cabinet is arranged on a stockpile arm and comprises a stockpile arm programmable logic controller (PLC) substation, a stockpile arm electric junction box and a stockpile arm on-site operating box; a stockpile belt is used for stockpiling, a material level height is detected by a material level detection sensor at the front end of the stockpile arm, the detected information is transmitted to the stockpile arm PLC substation, and the material level height is obtained through PLC calculation; when a material level reaches a set height, a stockpile swing motor is started to drive the stockpile arm to rotate, and an incremental encoder and an absolute value encoder are used for detecting the stockpile swing motor; and when the stockpile arm stops rotating after rotating an angular value X, stockpiling is carried out on a next stockpile point. With the stockpile swing mechanism control method for the top pile laterally-taking machine of the round stock yard, proposed by the invention, the stockpile swing mechanism can be automatically controlled, the stockpiling operation is fulfilled, the process is reliable, and manual intervention is not needed.
Description
technical field [0001] The invention relates to a control method, in particular to a control method for a stacking rotary mechanism of a top-stack side reclaimer in a circular stockyard. Background technique [0002] The top-stack side reclaimer in the circular stockyard is an important bulk cargo handling equipment. Due to its high efficiency and environmental protection, it is becoming more and more popular and widely used in coal yards and other places. For the model with no pitching function of the stacking arm, the structure of the side reclaimer at the top of the circular stockyard mainly includes a stacking belt mechanism, a stacking slewing mechanism, a reclaiming scraper mechanism, a reclaiming luffing mechanism, and a reclaiming rotary mechanism . Among them, the stacking belt mechanism and the stacking rotary mechanism belong to the stacking system. [0003] In the existing conventional technology, most of the power supply cables of the stockpiling system are dr...
