Multi-position self-aligning system with track movable type belt discharging trolley and control method thereof

Abstract

The invention discloses a multi-position self-aligning system with a track movable type belt discharging trolley and a control method thereof and belongs to the field of coal chemical industrial transportation equipment. The multi-position self-aligning system comprises a positioning structure and an electric control system. The positioning structure comprises a movable discharging trolley, a motor reducing gear, proximity switches, a cam, a mechanical brake mechanism, a trolley track, a travelling motor and a dust shield. The electric control system comprises an industrial control computer, a processor, an I / O (input / output) module card and a motor driver. The processor, the I / O module card and the motor driver are sequentially connected. The industrial control computer is connected with the processor through a network. According to the arrangement, a positioning method that rough positioning is combined with fine positioning is adopted to achieve low cost, high accuracy and mounting easiness.

Description

technical field [0001] The invention relates to the field of coal chemical transportation equipment, and more specifically relates to a multi-point automatic alignment system of a track-moving belt unloading trolley and a control method thereof. Background technique [0002] The belt conveyor unloading trolley is a separate part of the belt conveyor. It is mainly used in occasions where the belt conveyor has unloading requirements. Its function is the same as that of the unloader, but it can realize multi-point distribution and different location distribution. The belt conveyor unloading trolley is more convenient to use, but relatively expensive, and is suitable for use on large belt conveyors. [0003] At present, the control methods of the track-moving belt unloading trolley mainly include on-site manual alignment control and remote automatic alignment control. On-site manual alignment control requires full-time operators to operate the equipment in harsh environments su...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the problems in the prior art of the track-moving belt unloading trolley control system that the trolley cannot be aligned correctly due to the slippage between the wheels and the track, the overall cost is high and difficult to maintain, and the stability of the reflective sensor is poor. The invention provides a multi-point automatic alignment system and control method of a track-moving belt unloading trolley, which can adopt a positioning method combining rough positioning and fine positioning in the automatic transportation of large-stroke materials according to needs, so as to achieve low cost , high precision and easy installation
