Accurate alignment type coal discharging method for bucket trolley

Abstract

The invention relates to an accurate alignment type coal discharging method for a bucket trolley. The accurate alignment type coal discharging method for the bucket trolley comprises the following steps that (1) position detection devices are mounted on the bucket trolley and hoppers, a fixed-length induction block is mounted at one end of the bucket trolley, and proximity switches are mounted at top openings of the hoppers corresponding to the length of the bucket trolley and located below the bucket trolley; (2) the discharging hopper position of the bucket trolley is judged according to the pressing fit state between the induction block and the proximity switches and the operating direction of a belt for the bucket trolley; (3) the discharging hopper position information of the bucket trolley and the quantity of coal stored in a bucket are recorded in real time through a central control room; (4) a coal feeding plan for the bucket is made according to coal consumption and the quantity of the coal stored in the bucket; and (5) when the coal feeding hopper position in the coal feeding plan for the bucket is inconsistent with the discharging hopper position of the bucket trolley, an alarm is given and coal feeding is stopped. By adoption of the accurate alignment type coal discharging method for the bucket trolley, the position of the bucket trolley can be tracked in real time in the operating process, and the accident that coal with different qualities is mixed due to the fact that the bucket trolley discharges coal into the wrong hopper is avoided.

Description

technical field [0001] The invention relates to the technical field of coking, in particular to a method for accurately aligning and discharging coal with a trough trolley. Background technique [0002] The trough is composed of multiple hoppers, and the hopper trolley loads the washed coal of different types of coal into different hoppers on the top of the hoppers. [0003] The original hopper trolley was manually operated, and the on-site personnel adjusted the position of the hopper trolley according to the required coal type information orally transmitted by the hopper post and the coal loading information verbally transmitted by the stockyard personnel, and put the coal into the corresponding hopper . The bin number, coal type and material level of the coal washing lower hopper are all recorded manually. The on-site operating environment is poor, and it is impossible to monitor the running track of the hopper trolley and the number of the lower hopper warehouse. It is...

AI Technical Summary

Problems solved by technology

The on-site operating environment is poor, and it is impossible to monitor the running track of the hopper trolley and the number of the lower hopper bin. It is very easy for the hopper station to be misplaced. The operation of loading coal into the hopper cannot be detected and reminded in time during the process of loading the wrong coal, resulting in misplaced coal. bucket trough, the occurrence of mixed quality accidents

When the coal blending quality fluctuates, the coal loading process cannot be traced, and the cause of the accident cannot be clearly analyzed
