Abstract

The present invention relates to a snow removal truck, a snow removal truck rolling brush elevating control device, and a snow removal truck rolling brush elevating control method. The snow removal truck comprises a truck body and a snow removing device arranged at the front end of the truck body, and the snow removing device comprises a main rack, a rolling brush rack in hinge joint with the main rack, a rolling brush, an execution mechanism for driving the rolling brush to rotate, and a rolling brush elevating control device. The rolling brush elevating control device comprises a first sensor used for detecting the rotation angle of the rolling brush rack, a second sensor used for detecting the terrain clearance of the rolling brush directly and a controller. The controller calculates an actual height value according to the data detected by the first and second sensors, compares the actual height value with a preset height set value, operates a PID control algorithm, and controls the rolling brush to elevate to a set height according to the calculation result. According to the snow removal truck rolling brush elevating control device and the snow removal truck rolling brush elevating control method, the terrain clearance of the snow removal truck can be stable, and the operation personnel do not need to operate manually outside a cab in the cold weather, thereby improving the working comfort level of the workers.

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...

Embodiment Construction

[0025] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0026] The present invention firstly provides a rolling brush lifting control method of a snowplow, which includes the following steps:

[0027] Step 1: Detect the rotation angle of the roller brush rack through the first sensor and indirectly calculate the reference height of the roller brush from the ground, record the reference height from the ground as the first height, and directly detect the ground clearance of the roller brush through the second sensor height, recorded as the second height;

[0028] Step 2: subtracting the first height from the second height to obtain a deviation value,

[0029] If the deviation value is greater than the error setting value and remains for a period of time, it is determined that the sensor corresponding to one set of unre...
