Embodiment Construction
[0024] The specific implementation manners of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described here are only used to illustrate and explain the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.
[0025] figure 1 is a flowchart of a protection control method according to an embodiment of the present invention. The reclaimer includes a bucket wheel mechanism, the bucket wheel mechanism includes a bucket wheel and a hydraulic motor, and the hydraulic motor is used to provide rotational power for the bucket wheel, such as figure 1 As shown, the method includes the following steps:
[0026] In step S110, the rotation speed of the bucket wheel and the working pressure of the hydraulic motor are detected.
[0027] In step S120, the protection control of the bucket wheel mechan...

The embodiment of the invention provides a material taking machine bucket-wheel mechanism protection control method and device and a material taking machine, and belongs to the field of engineering control. The protection control method comprises the steps that the rotational speed of a bucket-wheel and the working pressure of a hydraulic motor are detected; and protection control over a bucket-wheel mechanism is started according to the rotational speed and the working pressure. By means of the material taking machine bucket-wheel mechanism protection control method and device and the material taking machine, protection control over the bucket-wheel mechanism of the material taking machine can be achieved, and the material taking machine can work continuously and efficiently.
Description
technical field [0001] The invention relates to the field of engineering control, in particular to a protection control method and device for a bucket wheel mechanism of a reclaimer, and a reclaimer. Background technique [0002] The bucket wheel reclaimer is an important storage yard operation equipment for coal and other materials, mainly composed of a traveling mechanism, a slewing mechanism, a pitching mechanism, a bucket wheel mechanism, and a cantilever belt mechanism. At the coal terminal, the main function of the bucket wheel reclaimer is to take the coal from the yard to the ground belt for the ship loader to load the ship. [0003] In the process of traditional manual operation, due to improper control of the height of the coal seam, the driving distance and the reclaiming rotation speed of the reclaiming operation, it is easy to cause the coal pile to collapse, the load of the reclaimer increases instantly, and the speed of the bucket wheel of the reclaimer slows ...
