摘要： The present invention discloses a multi-channel impact-resistant intelligent-constant-deceleration hydraulic braking system, and relates to the field of safety braking control for mine hoist systems. A technical point of the braking system is that the braking system includes a braking circuit formed by a constant-deceleration hydraulic system, a constant-deceleration electrical closed-loop control system, and a detection and feedback apparatus. The constant-deceleration hydraulic system is provided with N+1 independent complete oil return channels, where N is a positive integer greater than or equal to 3. The oil return channels are disposed in parallel to form parallel independent braking circuits, that is, are “multi-channel” and do not have a “common output point”. The oil return channel includes a backup oil source, an electro-hydraulic signal conversion and amplification component, an operating mode switching apparatus, and an execution component that are sequentially connected. The oil return channels include one backup channel and N working channels. Functions such as constant-deceleration braking, impact and vibration limiting, rope slip prevention, derailing prevention, and overwinding prevention can be safely and reliably achieved when a mine hoist system normally stops, performs operation braking or performs safety braking, thereby greatly reducing an accident rate.
