The end bracket mainly comprises a front double-row support type bracket and a rear two-column shield type bracket, and a closed type protection device and a connecting device of a traction mechanism are arranged on the rear bracket.
The forepoling of said return airway of the invention is formed by multiple reverse four bar linkage hydraulic supports with the same structure.
An optimized overall equipment model selection matching type of a working surface is characterized in that a smooth L-shaped net conveying channel is formed in the working surface.
The traction device mainly comprises a motor, a winding drum device, a base, a frequency converter and the like.
The drag reduction device mainly comprises a connector, a support and a roller.
The steering device mainly comprises a vertical roller and a connecting seat.
The traction rope is a standard type steel wire rope determined according to traction power.
