Multi-point intelligent driving scraping plate conveyor

Abstract

The invention relates to the field of scraping plate conveyors, in particular to a multi-point intelligent driving scraping plate conveyor. The multi-point intelligent driving scraping plate conveyor comprises a machine head frame assembly, a plurality of middle grooves, a scraping plate chain and a machine tail frame assembly, wherein the machine head frame assembly, the middle grooves and the machine tail frame assembly are sequentially connected through dumbbell pins, the scraping plate chain starts from the machine head frame assembly and passes through the upper portions of the middle grooves, after the scraping plate chain reaches the machine tail frame assembly, the scraping plate chain rotates back to the machine head frame assembly to form a closed chain, driving structures are installed on at least two of the multiple middle grooves, driving middle grooves are formed, driving structures are omitted inside the machine head frame assembly and the machine tail frame assembly, and chain wheel assemblies are further installed on the driving middle grooves. The scraping plate chain is installed on the chain wheel assemblies, the multi-point intelligent driving scraping plate conveyor is ingenious in design and reasonable in structure, the prior art does not need to be greatly improved, the economic benefits of a coal mine are effectively improved, and great popularization significance is achieved.

Description

technical field [0001] The invention relates to the field of scraper conveyors, in particular to a multi-point intelligently driven scraper conveyor. Background technique [0002] As the transportation equipment of the coal mine working face, the scraper conveyor not only undertakes the role of coal transportation, but also the running track of the coal mining machine and the fulcrum of the hydraulic support. At present, the scraper conveyor is generally equipped with two driving devices, which are respectively arranged at the head and tail of the scraper conveyor; the driving device transmits traction through the traction scraper chain, overcomes various running resistances, and drives the scraper conveyor to run; resistance The larger the tension, the greater the tension of the scraper chain, the greater the traction force required, the greater the power of the motor required, and the increase in power consumption; at the same time, the increase in tension increases the st...

AI Technical Summary

Problems solved by technology

At present, the scraper conveyor is generally equipped with two driving devices, which are respectively arranged at the head and tail of the scraper conveyor; the driving device transmits traction through the traction scraper chain, overcomes various running resistances, and drives the scraper conveyor to run; resistance The larger the tension, the greater the tension of the scraper chain, the greater the traction force required, the greater the power of the motor required, and the increase in power consumption; at the same time, the increase in tension increases the strength requirements of the scraper chain accordingly, which leads to Scraper chain bold

Moreover, the drive parts of the nose and tail are relatively large, resulting in problems such as lagging of the support at the end of the working face and insufficient space for pedestrians.

With the improvement of the production efficiency of the fully mechanized mining face, the installed power of the scraper conveyor is getting bigger and bigger, and the installed power can reach 3*1600KW at present. The smooth start and stable operation of the scraper conveyor under heavy load conditions are directly related to the scraper conveyor. The failure rate and service life of the plate conveyor and the production safety of the fully mechanized mining face, but it is difficult to achieve high reliability in reality
