Abstract

The invention discloses a device for detecting the brake performance of a disk damper brake of a friction type elevator. A speed photoelectric encoder is mounted at the shaft end of a friction roller; the speed photoelectric encoder is connected with a programmable controller of a data detection processing and control center; an electric eddy displacement sensor is mounted on a butterfly-shaped spring cylinder body of the disk damper brake; and the end face of the electric eddy displacement sensor and the end face of a damper brake shoe subjected to maximum wear maintain the same plane. The device can be applied to a mine friction type elevator and also can be applied to a mine winding type elevator and other mechanical equipment using the disk damper brake as a brake device.

Description

technical field [0001] The invention relates to a detection device in the field of electromechanical-hydraulic integrated control of a mine hoist, in particular to a braking performance detection device for a disc brake of a friction hoist. Background technique [0002] The friction hoist belongs to the position type mechanical equipment. Once the reliable braking is lost, phenomena such as self-rotation and sliding rope will occur, and major accidents such as hoist overwinding and over-discharging will occur. Mine friction hoists generally use disc brakes as braking devices. The disc brakes use butterfly springs to pre-compress to generate braking force, and the brake oil pressure is used to compress and loosen the brakes again. When the friction hoist is fully braked, the brake oil pressure is zero, and the disc brake relies on the pre-compression of the butterfly spring to apply positive pressure to the brake disc, and the brake disc generates friction to form a braking t...
