Self-portable belt conveyer

Abstract

The invention provides a self-portable belt conveyer, which comprises a belt conveying machine head, a hydraulic belt tightener, a belt conveyer middle part, a belt conveyer tail and a belt and is characterized in that the belt conveyer also comprises the belt conveying machine head and a dragging device connected with the hydraulic belt tightener; the machine head of the belt conveyer is the self-portable belt machine head, has the functions of free-installation and dismantling, easy maintenance, constructor reduction, labor intensity of constructor reduction, increasing working performance, creating safe operating environment, self moving a hydraulic dram tightening belt, free drag of tightening system and the like, and has the advantages of good explosion prevention and safe performance, high flexibility and the like. The self-portable belt conveyer increases the transportation technology of coal mine underground coal and rock, provides unitized technical equipment for coal mine coal and rock transportation system, and creates the fundamental conditions for realizing the safe production of big, medium and small-size coal mines.

Description

technical field [0001] The invention belongs to coal mine underground mechanical equipment, in particular to a coal and gangue belt transport equipment suitable for roadway excavation and working face mining in large, medium and small coal mines. Background technique [0002] At present, for coal mine roadway excavation, coal mining and gangue removal at the working face, fixed belt conveyors or scraper conveyors are generally used. The fixed belt conveyor includes a belt conveyor head, a hydraulic belt tensioning device, a middle part of the belt conveyor and a tail of the belt conveyor. These devices have the following problems: [0003] 1. The head roller, motor, and reducer of the fixed belt conveyor are split, with complex structure, large volume, difficult installation, high labor intensity, high failure rate, and low safety factor. [0004] 2. The overall length of the nose and belt storage bin of the fixed belt conveyor is 30-70 meters, and the equipment is too heav...

AI Technical Summary

Problems solved by technology

[0003] 1. The head roller, motor and reducer of the fixed belt conveyor are split, with complex structure, large volume, difficult installation, high labor intensity, high failure rate and low safety factor

[0004] 2. The head of the fixed belt conveyor and the entire length of the belt storage bin are 30-70 meters. The equipment is too heavy and not suitable for short-distance roadway excavation.

[0005] 3. The fixed belt conveyor has high requirements for the construction of the head chamber, which is difficult and has a long construction period.

[0006] 4. The tension belt transport mechanism is drawn by a winch or tensioned by an oil cylinder, the structure and control system are relatively complicated, and the safety performance is low

[0007] 5. The failure rate of the scraper conveyor equipment is high, the workload of equipment maintenance is large, the extension is difficult, the chute is manually lifted, and the labor intensity of the workers is high

[0008] 6. The existing fixed belt conveyor works in the rock roadway, which is not suitable for various short-distance roadway construction, Hengchuan construction, and chamber construction.
