Description
Technical Field
The utility model belongs to mine lifting means field, concretely relates to electromagnet disk brake device.
Background
The disc brake system of the existing mine hoisting equipment is completed based on a hydraulic transmission technology and a hydraulic proportional control technology. The hydraulic disc brake device is a brake execution unit for applying positive pressure to a disc brake system of the lifting equipment, and the hydraulic station is a power and control device for providing adjustable pressure oil for a brake system execution mechanism to realize work braking and safety braking. When the brake needs to be released, the hydraulic station oil pump works, the brake shoe leaves the brake disc by controlling the maximum working pressure of the proportional overflow valve to supply the brake, and when the brake needs to be released, the spring force acts on the brake disc at the maximum force by controlling the minimum working pressure of the proportional overflow valve to supply the brake.
As shown in fig. 1, a schematic structural diagram of a disc brake in the prior art is shown, and the specific working process is as follows: when high-pressure oil conveyed from a hydraulic station matched with a brake system enters an oil cavity Y, both the piston 3 and the brake oil cylinder 4 are stressed, the brake oil cylinder 4 is fixed with a brake bracket, namely a brake body 5, and cannot move, the piston 3 transmits force to a lining plate 6 with a cylinder body through the connecting bolt 2, so that the brake shoe 7 is driven to leave a brake disc, a gap is formed between the brake shoe 7 and the brake disc, and the brake is in a brake release state; at this time, the disc spring 13 in the cylinder is stressed, and the disc spring is deformed according to Hooke's law, so that the disc spring group is compressed. When the high-pressure oil pressure in the Y cavity slowly reduces, under the effect of the spring force of the disc spring 13, the brake shoe gradually moves towards the brake disc, after the brake shoe clings to the brake disc, if the oil pressure of the system continuously reduces, the spring force starts to gradually act on the brake disc, positive pressure is generated, when the oil pressure of the system reduces to the lowest value of the system, the positive pressure acting on the brake disc reaches the maximum value, the friction force generated between the brake shoe 7 and the brake disc is the working brake force of the elevator, and the elevator is in a normal working brake state. The change of the braking force can be realized by adjusting the oil pressure of a hydraulic station matched with the braking system. The electro-hydraulic pressure regulating device on the hydraulic station controls the change of oil pressure, and the electro-hydraulic pressure regulating device is controlled by a brake handle on the operation table in a manual operation mode and is controlled by a closed loop of an electric control system in full-automatic lifting. When the lifting equipment needs emergency braking due to an emergency in the lifting process, the oil pressure value of the brake system is quickly reduced to a preset value, after the preset time is delayed, the oil pressure is quickly reduced to zero, the brake acts on the brake disc with the maximum positive pressure, the friction force between the brake shoe 7 and the brake disc is the maximum braking force of the lifting system, and the lifting equipment is in a safe braking state.
Therefore, in the existing hydraulic disc brake system of the lifting equipment, if a brake signal is not received in a brake release state, a proportional overflow valve for supplying oil to a Y cavity needs to be always kept in a maximum working current working state, an oil pump needs to be kept in a maximum rotating speed to work, and the hydraulic disc brake system is high in noise, uneconomical and serious in energy consumption.
