Embodiment Construction

[0018] figure 2 As shown, the electric traction monorail crane multi-unit electric drive lifting beam control system, including monorail crane power battery 1, frequency converter 2, contactor 3, hydraulic pump station motor 4, hydraulic oil pump 5, monorail crane auxiliary hydraulic system 6, lifting motor 7. Lifting reducer 8. Control center 9.

[0019] The monorail crane power battery 1 supplies power to the frequency converter 2, and the output of the frequency converter 2 controls the motor 4 of the hydraulic pump station and multiple lifting motors 7 respectively. The motor 4 and the lifting motor 7 are connected in parallel. Inverter 2, which is connected to the control center. The motor 4 of the hydraulic pump station is connected with the hydraulic oil pump 5 to provide power for the auxiliary hydraulic system 6 of the monorail crane. The hoisting motor 7 is connected with the hoisting reducer 8 to provide power for the hoisting beam. The control center 9 communic...

Abstract

The invention provides a control system for multiple electrically driven hoisting beams by means of an electric traction monorail crane, and belongs to coalmine production auxiliary facilities. The control system comprises a monorail crane power battery, a frequency converter, contactors, a hydraulic pump station motor, a hydraulic oil pump, monorail crane auxiliary hydraulic systems, hoisting motors, hoisting speed reducers and a control center. The control system is characterized in that the monorail crane power battery supplies power to the frequency converter, the hydraulic pump station motor and the multiple hoisting motors are controlled by frequency converter output, the hydraulic pump station motor is connected with the hoisting motors in parellel, the front part of each motor is connected with one contactor, the hydraulic pump station motor is connected with the hydraulic oil pump, the hoisting motors are connected with the hoisting speed reducers, and the control center communicates with the frequency converter and controls on and off states of three contactors.

Description

technical field [0001] The invention is mainly used in the underground monorail crane track transportation system of the coal mine, belongs to the coal mine production auxiliary facilities, and specifically relates to the control system of the electric traction monorail crane with multiple electric drive lifting beams. Background technique [0002] In the monorail crane transportation system, the lifting transportation method is mainly used, and the lifting actuator mainly uses a hydraulic motor as the power source. [0003] figure 1 As shown, when multiple lifting and transportation beams work on the same monorail locomotive, the main problem of the power system with hydraulic system as the medium is low efficiency, especially on the electric traction monorail locomotive with battery as the power source. The problem is particularly prominent and obvious. Contents of the invention [0004] In order to solve the problem of low efficiency of the hydraulic lifting system, t...
