Wire transmission system for pressure signals of gap of brake shoe and pressure signals of butterfly-shaped spring

Abstract

The invention relates to a wireless transmission system for pressure signals of a gap of a brake shoe and pressure signals of a butterfly-shaped spring. The wireless transmission system comprises a disc-shaped brake shell, a wireless transmitter, a brake gap sensor and a butterfly-shaped spring pressure sensor, wherein a butterfly-shaped spring is arranged in the disc-shaped brake shell; the wireless transmitter is fixed in the center of the disc-shaped brake shell and is respectively electrically connected with the brake gap sensor and the butterfly-shaped spring pressure sensor; the brake gap sensor is arranged on the outer side of the disc-shaped brake shell; and the butterfly-shaped spring pressure sensor is abutted between the butterfly-shaped spring and the inner wall of the disc-shaped brake shell. The wire transmission system for the pressure signals of the gap of the brake shoe and the pressure signals of the butterfly-shaped spring is reasonable in structure and convenient to operate, is safe and reliable, and can monitor the pressure signals of the gap of the brake shoe and the pressure signals of the butterfly-shaped spring in real time; and problems that the brake shoes are out of order due to the pressure of the gap of the brake shoe and the pressure of the butterfly-shaped spring, so that a lifting machine is failed are solved.

Description

[0001] technical field [0002] The invention relates to a wireless transmission system for signals, in particular to a wireless transmission system for brake shoe clearance and disc spring pressure signals, which is applied to various equipment using disc gates and belongs to the technical field of mining equipment. [0003] Background technique [0004] The mine hoist is responsible for sending personnel and equipment into and out of the mine, and continuously bringing out the products under the mine. The location of the hoist is the throat of the mine and mine, and its safe operation is very important to the entire mine. [0005] The mine hoist lifts or lowers the cage through the wire reel, and the wire reel of the hoist does not rotate any more to prevent the wire reel from sliding down. If the disc brake cannot hold the wire rope reel, the cage will slide down. The force that the type brake hugs the reel is provided by the belleville spring. The brake shoe and belle...

AI Technical Summary

Problems solved by technology

The brake shoe and belleville spring of the disc brake are wearing parts. The brake shoe will gradually become thinner during long-term operation, which will increase the gap between the brake shoe and the wire rope drum, reduce the friction coefficient, and even make the The brake shoe fails, and the elastic coefficient of the belleville spring will change with time, both of which will become hidden dangers of major safety accidents in mines
