On-line monitoring device for winch

Abstract

The invention relates to an on-line monitoring device for a winch. The on-line monitoring device comprises a first monitoring device and a second monitoring device for monitoring the temperature of areel disc brake, the first monitoring device comprises a connecting rod hinged to a brake shoe of a motor high-speed shaft brake and a fixing support fixedly connected with a fixing base of the motorhigh-speed shaft brake, a supporting rod hinged to the connecting rod is fixedly connected to the fixing support, and a sensing part is arranged on the connecting rod. The sensing part and the brake shoe of the motor high-speed shaft brake are located at the two sides of the supporting rod respectively, and a proximity switch matched with the sensing part is installed on the fixing support. Through the arrangement of the first monitoring device and the second monitoring device, the action of the motor high-speed shaft brake and the temperature of the reel disc brake are monitored, so that real-time monitoring is achieved, the action of the high-speed shaft brake and the temperature of a brake disc are monitored in time, and the brake and related parts are adjusted or replaced in time underthe condition that production is not affected; and continuous production is achieved.

Description

technical field [0001] The invention relates to the technical field of brake on-line monitoring, in particular to the brake monitoring for hoisting machines, in particular to an on-line monitoring device for hoisting machines. Background technique [0002] The hoist is a kind of lifting equipment commonly used in the blast furnace smelting industry. It mainly includes two parts, the motor and the reel. The high-speed shaft of the motor is connected to the reducer through an elastic pin coupling. The output shaft of the reducer is connected to the central axis of the reel. In this way, the power of the motor is transmitted to the reel. Brake discs are installed at both ends of the reel, and the brake disc is braked by disc brake shoes. The output shaft of the motor is equipped with a motor high-speed shaft brake. The brake shoes of the brake brake the motor shaft.

AI Technical Summary

Problems solved by technology

[0003] However, when the elastic pin coupling rubs against the outer skin due to brake failure, it is easy to cause the elastic pin to melt and catch fire, resulting in excessive load on the motor, impact on the coupling, damage to the equipment, and needs to be replaced. Due to the limited space, the elastic pin should be replaced. Pillar pin coupling is quite difficult, it needs to stop the winch, slow down the blast furnace, and the operation time is long, which affects the production

When disc brakes have loose brake shoes or oil cylinder leakage, they need to be replaced. If they are not found, adjusted and replaced in time, it will also cause the winch to stop, the blast furnace to slow down, prolong the working time, and affect production.
