Description

technical field [0001] The invention relates to a disc brake auxiliary device for mines and a method for using the same, and belongs to the technical field of energy recovery and utilization during braking of belt conveyors for mines. Background technique [0002] Mine belt conveyor is equipment for coal transportation, and disc brake is the main part of its mechanical brake. When braking, the whole kinetic energy of belt conveyor is converted into heat energy, resulting in energy loss. The running speed of the belt conveyor is between 3m / s and 6m / s, which makes the initial speed of disc brake braking low and the energy conversion is difficult. In the process of disc braking, it is necessary to ensure the stable transportation of coal material, resulting in a long braking time, and the braking pressure is not stable enough, which reduces the service life of the friction pair. In view of the current working conditions of disc brakes, there are still the following deficiencie...

Problems solved by technology

In the process of disc braking, it is necessary to ensure the stable transportation of coal material, resulting in longer braking time, and the braking pressure is not stable enough, which reduces the service life of the friction pair

In view of the current working conditions of disc brakes, there are still the following deficiencies: First, when braking for a long time, the friction heat generated by the friction pair is relatively large, resulting in material wear and friction performance reduction, while shortening the service life of the disc brake; The second is that the braking torque is not stable enough, which causes the vibration of the whole machine and some noise; the third is that the generated frictional heat is dissipated into the environment, resulting in a waste of energy
