Abstract

The invention relates to an extra-large-mining-height high-voltage frequency conversion integrated drive type scraper conveyor, and belongs to the field of coal mine transportation equipment. The extra-large-mining-height high-voltage frequency conversion integrated drive type scraper conveyor comprises a machine head part, a machine tail part, a middle section and a circulating rotating scraper chain; the machine head part comprises a crossed side unloading machine head frame and is connected to the middle section through a transition slot; the middle section includes a middle slot, a skylight opening slot and a changeover slot, and one side of the middle section is equipped with a coal mining machine traction pin track and a cable groove; the machine tail part comprises an automatic telescopic machine tail frame; chain wheel assemblies on the machine head part and the machine tail part are connected with parallel transmission devices, and the chain wheel assembly on the machine headpart is also connected with a vertical transmission device; and the scraper conveyor is connected with a comprehensive mechanized coal mining face centralized control system, and the comprehensive mechanized coal mining face centralized control system is connected with an automatic speed regulation device. The extra-large-mining-height high-voltage frequency conversion integrated drive type scraper conveyor can be suitable for large coal mines being ten million tons or more, has the functions of automatic tensioning, automatic speed regulation and overload protection, can achieve smooth startunder the full load condition and improves the safety performance and the maintenance performance of the whole machine.

Description

technical field [0001] The invention relates to the field of transportation equipment for coal mines, in particular to an ultra-large mining height, high-voltage frequency conversion integrally driven scraper conveyor. Background technique [0002] With the advancement of coal mining technology, the scraper conveyor, as one of the key equipment for large-scale, efficient and continuous fully mechanized coal mining, continues to develop in the direction of perfect function, complex structure and automatic control, which affects the operation of scraper conveyor The number of factors has increased dramatically, and the potential risk of failure or failure has also increased. In the actual operation process, in addition to being affected by its own material and the underground environment, the scraper conveyor also bears a huge impact load, coupled with the influence of human factors such as untimely on-site maintenance and improper operation, it is easy to cause the scraper co...
