Abstract

The invention discloses a continuous milling machine and a traveling and loading control system. The traveling and loading control system comprises a controller, at least two paths of frequency converters, a traveling motor and a shovel motor, wherein the controller is connected with the frequency converter; the traveling motor and the shovel motor are respectively connected with the frequency converters; the frequency converters are used for detecting the working current of the traveling motor and / or the shovel motor; the controller receives the working current and controls the output signals of the frequency converters according to the magnitude of the working current; and the output signals are used for changing the rotating speed of the traveling motor and / or the shovel motor. According to the continuous milling machine and the traveling and loading control system, the frequency converters are connected with the traveling motor, so that the traveling speed can be changed in real time, and the traveling efficiency is improved; and besides, the frequency converters are connected with the shovel motor, so that the loading capacity of a star wheel of the shovel part is enhanced, and the loading efficiency is improved.

Description

technical field

[0001] The invention relates to the field of engineering machinery, in particular to a continuous mining machine and a traveling and loading control system. Background technique

[0002] At present, the traveling part and loading part of the continuous miner are controlled by hydraulic control system. Therefore, when the continuous miner is running in the empty roadway, if the continuous miner is in the state of no-load travel, its travel speed is limited by the hydraulic control system, and the speed of the hydraulic motor cannot be increased in real time. Therefore, the travel efficiency is low (due to the hydraulic pressure The pump control has only one speed, whether it is empty or full load, the speed cannot be increased, if the frequency conversion motor is used to work, the speed can be adjusted in real time); at the same time, when loading coal and rocks with different weights, the star wheel in the loading part The loading speed cannot be changed, a...
