Problems solved by technology

[0002] The belt conveyor is mainly composed of rollers, brackets, conveyor belt drive devices, etc. However, all kinds of rollers themselves do not have a braking function, and the conveyor needs to add a special brake to brake the equipment.
This concentrates the braking force and cannot realize the controllable braking of the belt conveyor, reducing the safety of the equipment

Abstract

The invention relates to a roller brake which comprises a box, a connecting bolt, a base plate, a bearing, a shaft, a sealing cover, a passive friction sheet, a passive drum, a passive drum oil opening, an active friction sheet, a disc spring, a brake oil way, a piston push rod, a hydraulic cylinder, a hydraulic cylinder oil inlet and a ventilation assembly. The box is connected with the ground through a foundation bolt; the brake oil way is connected with a brake oil pump; the hydraulic cylinder oil inlet is connected with a control oil pump; the passive drum is connected with the box; an axial oil way and a radial oil way are machined in the shaft, and a high-pressure sealing ring is arranged between the sealing cover and the shaft; outer teeth are arranged on the passive friction sheet and are connected with the passive drum; inner teeth are machined on the active friction sheet, and outer teeth are machined in the shaft matched with the active friction sheet; the hydraulic cylinder is designed outside the box; the active friction sheet and the passive friction sheet are installed in a spaced manner. The roller brake has the effects that the braking torque is stable, the braking impact is small, the braking accelerated speed is controllable, reliable braking is achieved when power is off suddenly, and power-off protection is achieved.

Description

technical field [0001] The invention relates to the field of material conveying equipment, in particular to a drum brake. Background technique [0002] The belt conveyor is mainly composed of rollers, brackets, conveyor belt drive devices, etc. However, all kinds of rollers themselves do not have a braking function, and the conveyor needs to add a special brake to brake the equipment. This concentrates the braking force and cannot realize the controllable braking of the belt conveyor, reducing the safety of the equipment. Traditional braking methods include mechanical friction braking, hydraulic braking, electrical braking, etc. This paper proposes a viscous brake for the drum, which uses the viscous shear force of the liquid to provide the braking torque. [0003] Chinese invention patent (application number: 201110140857.X application date: 2011-05-30) discloses a self-compensating controllable brake, including rollers, with pneumatic cylinders on both sides of the roller...
