Abstract

The invention discloses a full-automatic hydraulic bidirectional servo off tracking correction system. The system comprises a gear rack swinging oil cylinder, a left bidirectional pump and a right bidirectional pump, wherein the system is symmetric by taking the gear rack swinging oil cylinder as the center; the left bidirectional pump and the right bidirectional pump are distributed symmetrically; the left bidirectional pump and the right bidirectional pump are provided with a left friction wheel and a right friction wheel; a left end controlled closing one-way valve, an oil tank and a right end controlled closing one-way valve are connected in sequence from the left cavity of the gear rack swinging oil cylinder to the right cavity of the gear rack swinging oil cylinder along a first pipeline; and a right shuttle valve, a right bidirectional pump and a left shuttle valve are connected in sequence from the left end to the right end of the left bidirectional pump through a second pipeline. The full-automatic hydraulic bidirectional servo off tracking correction system does not need any power supply or electric control; the full-automatic hydraulic bidirectional servo off tracking correction system is resistant to wind blowing and rain, is corrected automatically, and is prevented from losing control; the system is fully enclosed, and is resistant to pollution; the full-automatic hydraulic bidirectional servo off tracking correction system is simple in structure, and is convenient to install and replace; and the full-automatic hydraulic bidirectional servo off tracking correction system has long service life and low failure rate.

Description

technical field [0001] The invention relates to a hydraulic system of hydraulic follow-up technology, in particular to a fully automatic hydraulic two-way servo deviation correction system. Background technique [0002] The working principle of the belt conveyor: the belt transports various solid materials from one place to the designated place under the drive of the motor. It mainly includes transmission device (motor, reducer, coupling, driving wheel, driven wheel, reversing wheel); rack device (belt conveyor support, idler roller and support); control and protection device (deviation switch, speed switch , pull rope switch); tensioning device (screw, counterweight, hydraulic three); belt and auxiliary device. [0003] However, there are always belt deviations during the transportation process, and there are many reasons for this. For example, the head and tail wheels and the belt bracket are not installed on the same center line, the idler roller is not perpendicular to...
