Abstract

The invention discloses a mining intrinsic-safety two-level belt sway switch. The mining intrinsic-safety two-level belt sway switch comprises a housing. The top of the housing is provided with a protruded part. The middle part of a cavity of the protruded part is provided with a push rod. A spring is sheathed on the push rod. The push rod is stretched into the housing. A rocker component is installed above the push rod. The rocker component comprises a deviation vertical roller, a connecting rod and a ball seat. The ball seat contacts with the push rod. The top of the ball seat is provided with the connecting rod. The end part of the connecting rod is provided with the deviation vertical roller. The central position of the top of the cavity of the housing is provided with two microswitches. The microswitches are positioned below the push rod, and two microswitches are alternately installed upwards and downwards. Two microswitches are connected with two sensors. Center lines of the housing and the rocker component are positioned in the same straight line. The mining intrinsic-safety two-level belt sway switch is rational and compact in structure and design, and has the pre-warningand warning functions.

Description

technical field [0001] The invention relates to the field of conveyor belt protection switches, in particular to a mine intrinsically safe two-stage deviation switch. Background technique [0002] The two-stage deviation switch is a product used to detect the deviation of the conveyor belt of the belt conveyor. It is a safety protection device that automatically alarms and stops the conveyor belt in the case of deviation. [0003] The working principle of the two-stage deviation switch is: when the conveyor belt deviates during the operation, the conveyor belt touches the switch vertical roller and deflects the vertical roller. When the deflection angle of the vertical roller reaches the first-level switching angle, the switch sends out an alarm signal. When the conveyor belt deviates seriously and reaches the 2-level switch angle, the switch sends a stop signal to realize the automatic shutdown of the conveyor belt deviation fault. When the deviation fault is eliminated an...
