Abstract

The invention provides a winch automatic deflection control method and device and a double-wheel slot milling machine, and relates to the technical field of engineering machines. The winch automatic deflection control method comprises the following steps that position information of a wire outlet part of a hose is obtained; a current deflection angle of a winch at the current position and a targetdeflection angle for the winch to be deflected are obtained; and the current deflection angle is compared with the target deflection angle, the action of a deflection oil cylinder is controlled according to a comparison result, and deflection of the winch is stopped if the difference value between the two deflection angles is smaller than a certain set value. The technical problems that in the prior art, a swing winch cannot achieve automatic swing control, and the control precision is poor are solved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a capstan automatic deflection control method and device and a double-wheel slot milling machine. Background technique [0002] In the prior art, the main slag discharge method of the double-wheel milling machine is to rely on the mud pump at the bottom of the milling tool holder to realize slag discharge, and the mud hose needs to be lifted and lowered synchronously with the double-wheel milling mud pump. [0003] In general technology, although the winch in the double-wheel slot milling machine can swing (or deflect), the position of the hose on the multi-layer winch cannot be obtained, and automatic swing control cannot be realized. Usually, the swing angle of the winch adjusted manually is quite different from the angle required by the actual hose, resulting in that the control accuracy cannot be guaranteed. Contents of the invention [0004] The purpose of t...
