Abstract

The invention discloses a safety control system and method for a drill jambo power unit, and belongs to the technical field of drill jambo control. The system comprises a cable drum, a slip ring box,a motor unit, a power inlet protection unit, a soft start control unit, an MCU, a CAN bus and a human-computer interface. A power supply cable is connected with the wire inlet end of the slip ring boxthrough a cable drum; the wire outlet end of the slip ring box is connected with the motor unit through the power inlet protection unit and the soft start control unit in sequence, the MCU is connected with the slip ring box, the power inlet protection unit and the motor unit, the MCU is connected with the soft start control unit and the human-computer interface through a CAN bus, and a motor monitoring unit is arranged in the motor unit. Impact-free soft start of the motor can be realized, the service life of the motor is prolonged, and impact of current on a power grid is avoided; the safety of the system is improved by monitoring the states of different parts and giving an alarm in real time.

Description

technical field

[0001] The invention belongs to the technical field of rock drilling jumbo control, and in particular relates to a safety control system and a control method for a power unit of a rock drilling jumbo. Background technique

[0002] Rock drilling jumbo (also known as drilling jumbo) is a kind of rock drilling equipment used in tunnel and underground engineering by drilling and blasting. It can move and support multiple rock drilling machines to perform drilling operations at the same time. Since the working environment of the rock drilling rig is relatively harsh, the requirements for each component of the rock drilling rig are relatively high. As a key component of a rock drilling rig, the power unit is of great value and requires high enough reliability to meet the needs of the rock drilling rig under complex working conditions.

[0003] At present, the power unit of rock drilling rigs mainly uses electric motors, and the motors used in rock drilling rigs ar...
