    摘要: In existing mine hoists, much of the complex equipment needed for automatic control is located at the working levels in the mine where environmental conditions are poor. According to this invention, the complex equipment needed for automatic control of the hoist is located in the same room as the hoist drive where the environment is warm and dry. This is achieved through the use of control equipment of a type that responds to the coded pulses generated in the Bell Pull circuit in the way that the operator responds to the ringing of his bell or flashing of his light. In essence, this equipment duplicates the responses of the operator in that it counts pulses, distinguishes between sets of pulses, remembers this, exercises a degree of logic, and applies the information for control purposes. Moreover, it can be located in the same room as the hoist drive where it is dry and warm. The existing Bell Pull system or an equally simple circuit can now be used for sending the appropriate signals from the various mine levels to the control equipment. An operation selector is provided for selecting a mode of hoist operation between automatic or manual through a suitable connection with the Bell Pull circuit. When operation is manual control, the signals sent by the Bell Pull will, of course, be displayed to the operator.

    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.

    摘要: In a monitoring system for the gates of a mine lift shaft, each gate has a switch and a square wave is generated in a signal station and connected to a transistor inverter beyond each switch. When the switch is in the closed (safe) position, the transistor inverter is connected in circuit and the inverse of the waveform is transmitted back to the signal station. When the switch opens the transistor is shorted out and thus the returned waveform is in phase with the transmitted waveform. The various conditions which may be received at the signal station are detected and only if the switch and cable are operating correctly is the gate closed condition indicated. The use of a square wave and a changeover switch ensure that both conditions of the switch produce a definite signal at the signal station, thus any failure in the cable or switch prevents the received waveform from being the inverse of the transmitted waveform. This is detected by the signal station as an unsafe condition and if it is due to a fault this is also indicated.
