Electric hydraulic brake: Knowledge related to conveyors, belt conveyors, belt conveyors, bulk material conveying equipment, and the role and maintenance methods of brakes in belt conveyors! The installation of brakes in the belt conveyor is mainly to prevent the belt from reversing during emergency stops or shutdowns, and to avoid accidents caused by materials piling up at the tail of the conveyor due to the reversal. So how should we do a good job in correct use and daily maintenance during use? Today, the technical personnel from the manufacturer of Coryson belt conveyor will provide you with a detailed introduction! Maintenance methods for brakes. The brake is easily infected with oil stains at the driving equipment. To avoid affecting the braking effect, the adjacent oil stains should be promptly sorted out. When the driving wheel of the belt mechanism shows cracks and the thickness of the brake wheel flange reaches 40% of the original thickness, it should be discarded. The overall trend in the development of open-pit mining technology both domestically and internationally is towards large-scale mining, continuous production, and modern equipment. With the technological progress of mining technology and equipment in the open-pit mining industry worldwide, mobile belt conveyors, displacement belt conveyors, and semi displacement belt conveyors are the main technical equipment for open-pit mining. Their characteristics are that the belt conveyor uses a displacement machine to pull steel rails or skids to achieve horizontal movement of the entire machine. In addition, this machine also has the characteristics of long transportation distance, large transportation volume, and no fixed foundation, Safety devices to prevent walking and check parking. The brake is responsible for the stopping speed of the conveyor, reducing the stopping time under technically permissible conditions, commonly known as emergency braking. Once an accident or a sign of an accident occurs, the operation can be stopped as soon as possible to prevent the accident from happening or expanding. The type of braking device

There are many types of brakes for belt conveyors, and different forms of brakes can be selected based on the technical performance and specific usage conditions of the conveyor (such as power size, installation angle, etc.). Commonly used include belt type backstop, roller backstop, hydraulic electromagnetic brake shoe brake, and disc brake. Belt type backstop

Hydraulic push rod brake

The hydraulic push rod brake can be used for both upward and downward conveyor belts, installed on a high-speed shaft, with fast and reliable action. Belt conveyors are generally equipped with this type of brake.

The structural principle of the disc brake is shown in the figure. Using fluid to push the brake shoe axially towards the brake disc through the oil cylinder, causing friction and braking. Each set of brakes has four oil cylinders, which are uniformly controlled by a hydraulic system. This type of brake is commonly used for high-power, long-distance and strong belt conveyors and steel rope traction belt conveyors, and can be installed on high-speed shafts. This type of brake is characterized by high braking torque, good heat dissipation performance, adjustable oil pressure, and infinitely adjustable braking torque during operation.

The selection of brakes should consider the following points:

1. Mechanical operation status, calculate the load torque on the shaft, and have a certain safety reserve.

2. The task of the brake shall be paid full attention to. It shall be selected according to different tasks. The brake torque supporting the brake must have sufficient reserves, that is, to ensure a certain Factor of safety. The mechanism with high safety requirements needs to be equipped with dual brakes.

3. The brake should ensure good heat dissipation function to prevent harm to personnel, machinery, and the environment. When the conveyor is conveying upwards, it is necessary to prevent the conveyor belt from reversing during parking, and the braking at this time is generally referred to as backstop. When conveying downwards, it is necessary to prevent the conveyor belt from moving forward when parking, which is called braking. The conveyor should be designed with a braking device based on its working conditions. The braking force required for the transmission drum should be determined separately based on the conveyor's horizontal, upward, and downward movements.
