Single-tube multi-pole safe sliding line type combined coding alignment method of unloading trolleys

Abstract

The invention discloses a single-tube multi-pole safe sliding line type combined coding alignment method of unloading trolleys. The alignment method is applied to alignment of material bins of the unloading trolleys on grooves of metallurgy, coal and cement industries. According to the alignment method, a single-tube multi-pole small-capacity multi-pole safe sliding contact line is utilized, a current collector is used to move in the whole process, according to the situation that heavy unloading vehicles need to be parked and unloaded in the material bins, binary code arrangement is carried out in the single-tube multi-pole small-capacity multi-pole safe sliding contact line, different material bin sections and different poles are provided with copper bar sections, the copper bar sectionsare connected with a power source through a middle power supply device, and then electrical signals of the copper bar sections are externally guided to a PLC system through the current collector device so that the position of the heavy unloading vehicles can be judged to be parked and unloaded through the binary code arrangement received by the PLC system, and also multi-point or back-and-forth continuous unloading of one bin section are carried out on the copper bar sections arranged corresponding to ore bins of the heavy unloading vehicles. According to the alignment method, the material storage amount can be increased, the feeding frequency of each bin can be reduced, and operation cost can be saved; and the stock bins can be considered to be designed to be smaller, construction investment is reduced, and good popularization and application values are achieved.

Description

technical field [0001] The invention relates to a position alignment method for loading and unloading trolleys on various feeding troughs in metallurgy, coal, cement and other industries. Background technique [0002] At present, in the metallurgy, coal, cement and other industries, the alignment methods of various loading troughs and unloading trolley silos generally adopt a proximity switch in the middle of each silo, an encoder for the motor shaft of the unloading trolley, and an encoder for the unloading trolley. There are three ways of setting gray bus on the track side. The proximity switch can only be used for point positioning and unloading and is susceptible to misoperation due to magnetic dust interference. Although the encoder can achieve continuous positioning, there is the problem of wheel slip accumulation error. Gray bus can realize continuous positioning but the system The overall project cost is too high. Contents of the invention [0003] The purpose of ...
