Electric control synchronization and rectification method of gantry crane and device thereof

Abstract

The invention discloses an electric control synchronization and rectification method of gantry cranes and a device thereof. Two sides of the gantry cranes traveling are provided with two sets of detection devices which are controlled by programmable controllers respectively, detection sensors are arranged on a fixed device corresponding to the detection devices arranged in the gantry cranes and maintenance workshops, whether the traveling on both sides of the gantry cranes is synchronous is judged by the time when the detection devices arranged for the gantry cranes go through the detection sensors in the maintenance workshops, and the detected signal is fed back to the programmable controller for rectification control so as to synchronize the traveling on both sides of the gantry cranes.The electric rectification control of the gantry cranes can rapidly and accurately align two gantry cranes with rails of electrolytic (overhaul) houses, and can rapidly transport default multifunctional overhead traveling cranes for electrolysis (electrolyte tanks) from the electrolytic houses; the repaired multifunctional overhead traveling cranes for electrolysis (electrolyte tanks) can be rapidly transported to and brought into use in the electrolytic houses.

Description

Technical field: [0001] The invention relates to an operation method and equipment in the aluminum smelting industry. In particular, it refers to an electrical control method and device for a gantry car, which is mainly used in equipment such as an electrolysis car in an electrolysis workshop. Background technique: [0002] At present, the development of the domestic aluminum industry has sprung up by leaps and bounds, and the old enterprises are constantly renovating and expanding their production capacity. The multifunctional electrolytic cranes and electrolytic cells are doubled and put into use, especially the emergence of large prebaked electrolytic cells. The magnetic field of the electrolytic workshop is getting stronger and stronger. The on-line maintenance of multi-functional electrolysis has brought great inconvenience, resulting in an increasingly urgent demand for centralized maintenance of multi-functional aluminum electrolysis units and electrolytic cells. The...

Problems solved by technology

At present, the gantry car system equipment used in China is mainly operated manually, and no deviation correction and synchronization measures have been taken. Due to actual mechanical manufacturing errors, motor speed errors and other reasons, the use effect of the gantry car system is not ideal: (1) Two The running of the gantry cars is not synchronized, and the tracks on the two gantry cars cannot be well connected with the two tracks of the electrolysis (overhaul) workshop at the same time, and a single unit needs to be adjusted; Skew, the two ends of the track on the gantry car cannot be docked with the track in the electrolysis (overhaul) workshop at the same time, there is a large deviation, which affects the smooth driving of the electrolysis multi-function overhead crane that needs to be repaired in the electrolysis (overhaul) workshop to the gantry car superior
