Snowplow and snowplow roller brush lifting control device and method

Abstract

A snowplow and a rolling brush lifting control device and method for the snowplow. The snowplow includes a car body and a snow plowing device arranged at the front end of the car body. The snow plowing device includes a main frame and a rolling brush frame hinged on the main frame , a rolling brush, an actuator that drives the rolling brush to rotate, and a rolling brush lifting control device. The rolling brush lifting control device includes: a first sensor for detecting the rotation angle of the rolling brush frame, a second sensor for directly detecting the height of the rolling brush from the ground, and a controller. The data detected by the sensor calculates the actual height value, and compares the actual height value with the preset height setting value, runs the PID control algorithm, and controls the roller brush to rise and fall to the set height according to the calculation result. The rolling brush lifting control device and method of the snowplow vehicle can keep the height of the snowplow vehicle stable from the ground, and prevent operators from performing manual operations outside the driver's cab in cold weather, thereby improving the comfort level of workers' work.

Description

technical field [0001] The invention relates to a snowplow, in particular to a rolling brush lift control system and method on the snowplow. Background technique [0002] The snow plow with a roller brush cleans the snow through the rotation of the roller brush. At present, when this type of snow sweeper cleans the snow on the road surface, the driver manually adjusts the height of the roller brush from the ground through a mechanical device, and then carries out the snow clearing work. However, in the actual working process, due to factors such as undulating terrain, wear of the roller brush, and deformation of the supporting wheels, the height of the roller brush from the ground is unstable, and the normal cleaning effect cannot be achieved. At this time, the driver needs to go out of the cab to visually inspect the roller. The height of the brush from the ground can be manually adjusted to raise and lower the height of the roller brush so that the roller brush has a suit...

AI Technical Summary

Problems solved by technology

However, in the actual working process, due to factors such as undulating terrain, wear of the roller brush, and deformation of the supporting wheels, the height of the roller brush from the ground is unstable, and the normal cleaning effect cannot be achieved. At this time, the driver needs to go out of the cab to visually inspect the roller. The height of the brush from the ground can be manually adjusted to raise and lower the height of the roller brush so that the roller brush has a suitable pressure on the road surface to achieve a good snow removal effect

However, if the driver frequently goes out of the cab in the cold winter, the driver's body will be frostbitten and the snow removal effect will be reduced.
