Variable speed control mechanism for large transport ship deck line-marking vehicle

Abstract

The invention relates to a variable speed control mechanism for a large transport ship deck line-marking vehicle. The variable speed control mechanism comprises a loading plate, a motor is fixedly arranged at the left end on the loading plate, and the motor is connected with a rocker; one side, deviated from the motor, of the rocker is hinged with a rack; a supporting bracket and a bearing seat are both arranged at the middle part of the loading plate; a great circular wheel is mounted on the supporting bracket in a rotatable way, and a movable slot for installing the rack in the sliding way is formed in the great circular wheel; an output rod is arranged on the bearing seat, and a pinion engaged with the rack is arranged at the left part of the output rod. The variable speed control mechanism disclosed by the invention is high in automation degree, the output shaft can be effectively controlled to alternatively run in fast rotation and slow rotation by controlling the eccentric rotation of the rocker and the cooperative rotation of the wheel and the pinion, thereby guaranteeing that two rotation periods are same, and achieving the effects of indirectly and conveniently controllingthe translation speed and length of a hairbrush, and guaranteeing that the interval between two solid lines is greater than the length of the solid line when performing line marking.

Description

technical field [0001] The invention relates to a construction machine, in particular to a variable speed control mechanism for a deck marking vehicle of a large transport ship. Background technique [0002] Generally speaking, large or super-large ships used for container shipping must use a large number of transport forklifts when handling or unloading containers. In order to regulate and guide the forklifts on the ship's deck to drive steadily according to the established route The best way to do this is to draw lane lines on the deck of the ship. In the lane dividing line, the lane dividing line between the lanes in the same direction is usually a dotted line, that is, it is composed of solid lines with intervals between each other. When actually marking the line, the screw nut can be used to drive the paint The brush slides horizontally on the ship deck to paint the solid line, and then lifts the brush up and separates from the ship deck to generate a marking interval,...

But nowadays, in order to save paint, the interval between every two solid lines is usually greater than the length of the solid line, but this is undoubtedly difficult to control and realize
