Telescopic high baffle safety protection device for front scraper conveyor head

Abstract

The invention provides a telescopic high baffle safety protection device for a front scraper conveyor head, and relates to the field of coal mining safety. The telescopic high baffle safety protectiondevice is structurally characterized in that a groove is formed in the middle of a baffle, wherein a telescopic plate is arranged in the groove; a shaft seat B is fixedly arranged at the bottom of the baffle; a shaft seat A is arranged on the upper portion of the telescopic plate; holes are formed in the shaft seat A and the shaft seat B; holes are formed in two ends of a jack; a pin penetrates two ends of the jack and the holes in the shaft seat A and the shaft seat B and fixes the jack; and a pin hole is formed in one end of the pin. The telescopic high baffle safety protection device has the advantages that the safety of operators can be guaranteed when the operators pass a fully mechanized caving face, large coal gangue is prevented from escaping, and the device is simple and convenient to operate. The telescopic high baffle functions in isolation and protection, and working hours of the operators for manually cleaning flying coal gangue are saved. Safety problems are prevented bythe telescopic high baffle of the front scraper conveyor head in the safety production process, the coal gangue is isolated inside a coal conveying channel, labor is saved, and the labor intensity ofthe operators is reduced.

Description

technical field [0001] The invention relates to the field of coal mining safety, in particular to a safety protection device for a retractable high-grade board at the head of a front scraper conveyor. Background technique [0002] With the development of coal mining technology, fully mechanized caving face is gradually applied and developed in my country's coal mining technology. It provides guarantee and prerequisite for the mining of dipped coal seams. The safety protection of fully-mechanized caving equipment in complex coal seams and large-inclination fully-mechanized caving faces is an important guarantee for safe production. In the current stage of fully-mechanized caving face coal mining equipment, safety protection devices are regarded as one of the important standards for design and manufacture. However, the safety protection of mass-produced fully mechanized coal mining equipment is mostly designed and manufactured based on common characteristics. In this design co...

Problems solved by technology

The safety protection of fully-mechanized caving equipment in complex coal seams and large-inclination fully-mechanized caving faces is an important guarantee for safe production. In the current stage of fully-mechanized caving face coal mining equipment, safety protection devices are regarded as one of the important standards for design and manufacture. However, the safety protection of mass-produced fully mechanized coal mining equipment is mostly designed and manufactured based on common characteristics. In this design concept, many individual problems are ignored. In terms of safety protection, it can satisfy most coal mining enterprises, but there are still some problems. Inadequacies
