Embodiment 1

[0032] Please refer to figure 1 as shown, figure 1 It is a schematic flowchart of a method for controlling the angle of a half-gantry scraper reclaimer provided by an embodiment of the present invention.

[0033] In this embodiment, the method for controlling the angle of the half-gantry scraper reclaimer specifically includes the following steps:

[0034] S101. Set the angle corresponding to the entire stockpile to several angle intervals.

[0035] S102. Calculate each step angle in each angle interval by using a linear interpolation formula.

[0036] S103. The controller detects the current angle value of the retrieving arm, determines the angle interval in which the angle value is located according to step S101, and determines the step angle corresponding to the angle interval according to step S102.

[0037] S104. Control the reclaiming arm to descend according to the step angle determined in step S103.

[0038] S105. Return to execute steps S103-S104 in a loop until t...

Embodiment 2

[0045] Based on the method for controlling the angle of the half-gantry scraper reclaimer provided in the first embodiment above, this embodiment provides an angle control device for the half-gantry scraper reclaimer, which specifically includes:

[0046]The stockpile angle interval setting module is used to divide the corresponding angle of the entire stockpile into several angle intervals.

[0047] The step angle calculation module is used to calculate each step angle in each angle interval through a linear interpolation formula.

[0048] The step angle determination module is used to detect the current angle value of the reclaiming arm through the controller, determine the angle interval where the angle value is located according to the angle interval set by the material pile angle interval setting module, and determine according to the calculation result of the step angle calculation module The step angle corresponding to this angle range.

[0049] The descending control ...

Embodiment 3

Abstract

The invention discloses a half-gantry scraper reclaimer angle control method, device and storage medium. In the method, the angle corresponding to the entire material pile is set to several angle intervals, and the angle within each angle interval is calculated by a linear interpolation formula. For each step angle, the controller detects the current angle value of the reclaiming arm, determines the corresponding step angle according to the angle range where the angle value is located, and then controls the reclaiming arm to follow the determined stepping angle within the angle range. angle to descend. The invention effectively solves the problem that due to the shape of the stockpile, the higher the stockpile, the contact area between the scraper and the material is small when the initial material is taken, and the scraper can plunge into the deeper material. As the height of the stockpile decreases, the scraper will As the contact area with the material increases, the scraper still penetrates into the material at the same depth, causing the current of the scraper motor to gradually increase to overcurrent, and at the same time, the output of the material increases, resulting in material overflow and belt overload.

Description

technical field [0001] The invention relates to the technical field of control of a half-gantry scraper reclaimer, in particular to a method, device and storage medium for controlling the angle of a half-gantry scraper reclaimer. Background technique [0002] The half-gantry scraper reclaimer is mainly used for reclaiming bulk or powder materials, such as coal, various ores, clay, gypsum and other materials. It is currently used in mines, docks, steel mills, power plants, cement plants And other widely used large-scale stockyard reclaiming equipment. However, the existing semi-gantry scraper reclaimer has a low degree of automation, and a large degree of intervention and manipulation by the staff is required at the work site of the stacker reclaimer, especially when scraping and reclaiming often occur. The current of the plate motor increases to over-current, and the output of materials increases at the same time, resulting in material overflow and belt overload, which seri...
