Control method, control device and control system for automatic stacking of stacker

Abstract

The invention discloses a control method, a control device and a control system for automatic stacking of a stacker. The control method for the automatic stacking of the stacker comprises the steps of receiving an automatic stacking command, controlling a big arm of the stacker to nose up by a predetermined height under the condition that height of the last stack among the stacks which are stacked by the stacker reaches to a predetermined height, controlling the stacker to travel in the second direction opposite to the first direction under the condition that the height of the stack reaches to a second predetermined height, controlling the big arm of the stacker to nose up to a predetermined height under the condition that the stacker reaches to a predetermined position, controlling the stacker to travel towards the first direction under the condition that the height of the present stack reaches to a third predetermined height, and controlling the stacker to return to the position of the last stack. Stacking is carried out when the big arm of the stacker noses up and then the stacker travels.

Description

technical field [0001] The invention relates to the field of control of stockers, in particular to a control method, control device and control system for automatic stacking of a stocker. Background technique [0002] The stacker is an important equipment in the coal port. The stacker has a one-way stacking function. The material is conveyed to the stacker through the ground belt, and falls onto the cantilever belt through the tail car and the center funnel, and then driven by the driving roller, the material is transported to the cantilever head along with the belt from the dropping place. The reversing roller at the bottom, and finally throw the material at the reversing roller to realize the transportation of the material from the ground belt to the yard. The stacker mainly adopts the fixed-point stacking method during operation. First, adjust the boom frame to an appropriate height. During the stacking process, adjust the stacking height of the forearm while stacking, u...

Problems solved by technology

Although the stacking method in the prior art has low power consumption and simple operation, peaks and valleys will be generated during stacking. Therefore, before the operation is completed, the stacker driver must slide the stack to fill the peaks and valleys. In order to improve the efficiency of reclaiming

Generally, when the stacker driver performs stacking, he mainly judges the timing and method of stacking based on his own experience, so it is often difficult to control the stack shape, and the orderliness of the stack shape will directly affect the reclaiming of the reclaimer.

For example, when the stack is irregular (for example, there is a hump stack), the reclaimer needs to consume more energy to complete the reclaim, which reduces the stability of the reclaimer
