2. The utility model provides a be applicable to coke oven brick gas duct cleaning device and application method thereof which characterized in that: the cleaning device suitable for the coke oven brick gas channel comprises the following components in part by weight:
firstly, opening a cover of a brick gas channel (1) to be cleaned, aligning a multi-sharp-corner impact head (4) of the cleaning device to the center of a hole of the brick gas channel (1), and then stably fixing a base (14) perpendicular to the ground to prevent shaking in the cleaning process;
the power supply of a variable speed controller (13), a motor A (15) and a motor B (16) is switched on, then a lifting start button A (17-1) is turned on, a connecting arm A (6), a connecting arm B (9) and a connecting arm C (11) of the cleaning device start to lift, a multi-cusp impact head (4) is observed to reach the position of a blockage (2) through a monitoring video (18), at the moment, a start button B (17-2) is turned on, the whole cleaning connecting arm starts to rotate from slow to gradual to fast, so that the whole cleaning connecting arm drives the cusp impact head (4) to rotate from slow to gradual to fast, and the blockage (2) starts to be dredged and cleaned;
observing the cleaning effect through the monitoring video (18), continuously deeply pressing the start button B (17-2) for a long time under the variable speed control of the controller (13), wherein the speed of cleaning the impact head (4) is faster and faster, if the blockage (2) is cleaned, the blockage is slightly pressed to not be pressed, the rotating speed of the cleaning impact head (4) is slower and slower, and finally stopping pressing and simultaneously stopping pressing the rising start button A (17-1), so that the impact head does not rise any more;
and then pressing a descending start button A (17-1), starting contraction of the whole connecting arm of the cleaning device, finally returning to the place, and cutting off power switches of the variable speed controller (13), the motor A (15) and the motor B (16) to finish cleaning of the brick gas channel (1).
