In order to prevent the tail of the coal mining scraper conveyor from being pulled up when it is subjected to greater resistance, the current fixing method adopted by the tail pressure column of the coal mining scraper conveyor has a low safety factor. The length of the pressure column directly affects the setting effect. When the slab conveyor is at the end, the pit wood pressing column is almost always replaced, which wastes pit wood. Therefore, the existing coal mining scraper conveyor tail pressing column must be improved.
Since the tail of the coal mining scraper conveyor is extended each time, the length of the pit wood pressure column is inconsistent due to the height of the roadway, which directly affects the laying quality. After the top of the pit wood pressure column is stressed, it is easy to be crushed, and the pit wood pressure column is inconvenient to install and use. It must be fixed with a small card cable when it is set on the bracket.
After the improvement of the tail pressure column of the coal mining scraper conveyor, the length of the pressure column can be adjusted according to the needs of the site through the hydraulic cylinder, which is convenient and quick. The U-shaped steel section sleeve on the top is directly connected with the U-shaped steel beam, and the contact surface is firm and reliable to avoid sliding.
The tail pressure column of the telescopic coal mining scraper conveyor is equipped with 6-inch steel pipe sleeves at both ends of the pit wood to avoid the phenomenon of pit wood pressure split at the top, improve work efficiency and enhance the safety factor. The tail pressure column is composed of three parts, which are the cylinder part, the connecting part and the pit wood part, which are easy to install and disassemble.
