Sensor position Tail Block DOL

.

The sensor DOL is designed to measure the angular displacement of the drill winch shaft and, accordingly, the linear movement of the tramline block.

The position sensor of the TAL block is installed on the basis of the jacket of the drill winch on the side of the input of the pneumatic line of the brake actuator and connected to the winch shaft by a wedge strap, which has a regulated tension.

The principle of operation of the speed sensor of the winch DOL is based on the transformation of the angle of rotation of the shaft drill winch into a two-phase electric signal (phase shift of 90 °), from which the pulsed signals of the required form and value are formed.

The sensor DOL consists of a measuring block mounted on the mounting stand and a set of V-belt pulleys. In the middle of the measuring block is a board with photovoltaic converters and disk, with dense cutouts, which is fixed on the shaft of the block.
