Problems solved by technology
In the prior art, there is no special equipment for the installation of the coal delivery chute. During the installation of the coal delivery chute, the unloading, handling and assembly of the middle chute are completed by manpower unloading, winch dragging, and manual assembly.
In this way, the labor intensity of installing the coal delivery tank is relatively large, the installation speed is very slow, the work efficiency is very low, and there are many potential safety hazards.

The invention has the advantages that the lifting tool car of the fully-mechanized equipment can be provided with a middle groove, a machine head and tailequipment during the installation of a scraper conveyer of the fully-mechanized equipment, thereby having low labor intensity of installation operation, fast installation, high work efficiency and good safety of the installation operation; the lifting tool car is provided with the stepping travelling devices, thereby being convenient to move; and in addition, the telescopic ceiling posts are connected to the hydraulic telescopic upright posts, thereby being beneficial for the work safety.
Description
technical field [0001] The invention relates to a device used in the installation of a complete set of fully mechanized mining equipment in a coal mine, in particular to a hoisting vehicle for a central trough of a scraper conveyor coal delivery trough in a fully mechanized mining face. Background technique [0002] The scraper conveyor in the fully mechanized mining face of the coal mine is an important equipment for the complete set of fully mechanized mining equipment in the coal mine. The scraper conveyor is located at the front and bottom of the fully mechanized mining face, and is used to transport the coal mined by the shearer from the working face in a timely manner. The scraper conveyor has front and rear conveyors at both ends of the fully mechanized mining face. Between the front and rear conveyors is a coal delivery trough connected in turn by multiple middle slots. There are chains driven by the front and rear conveyors in the coal delivery trough. Scrapers are...
