Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] The underground scraper includes a working device, a power device, and a walking device, among which the working device includes a bucket, a boom, a connecting rod, a rocker arm, a tilting cylinder, and a lifting cylinder. The working process of the underground scraper is mainly reflected in the working device, and its action is composed of five working conditions, insertion working condition, shovel loading working condition, lifting working condition, unloading working condition and automatic leveling working condition. The present invention mainly occurs in the insertion working condition and the shovel loading working condition. Because gangue, large stones, etc. that are heavy or fixedly connected to the ground will be arranged in the stockpiling material, that is, the dense nucleus will hinder the insertion and shoveling ...

Abstract

The invention discloses an intelligent drag reduction control system and method for an underground carry-scraper. The control system comprises a controller, a pressure sensor, an angle sensor and a speed sensor; the pressure sensor, the angle sensor and the speed sensor are electrically connected with the controller; the controller is used for receiving signals sent by the pressure sensor and theangle sensor and judging whether drag reduction control is adopted for a bucket or not; the pressure sensor is used for detecting resistance borne by the bucket; the angle sensor is used for detectingwhether the bucket is in a horizontal state or not; and the control system further comprises a bucket lifting valve, a bucket tipping valve, a bucket descending valve and a bucket collecting valve which are electrically connected with the controller. According to the intelligent drag reduction control system and method for the underground carry-scraper, by receiving signals of the sensors and executing the drag reduction action through a valve body, automatic and intelligent operation is achieved, the working efficiency is improved, and the service life of the underground carry-scraper is prolonged.

Description

technical field [0001] The invention relates to an underground scraper, in particular to an intelligent drag reduction control system and a control method for an underground scraper. Background technique [0002] The underground scraper is mainly used for ore removal and slag removal in the stope of underground mines. It is mainly used for shoveling and transporting loose materials after blasting. It is the main equipment for trackless mining in underground mines. During the shoveling operation of the underground scraper, due to different geological conditions and operating environments, the stress on the bucket is more complicated, and similar dense cores such as large rocks are often encountered, resulting in increased resistance to the bucket. The traditional mode of operation is based on the operator's observation or experience judgment, and performs operations such as lifting the boom, retracting the bucket, and advancing the equipment, and repeats the operation until i...
