Abstract
The research rationale aimed at development and use of the slider-crank mechanism in the mining equipment is justified. The advantages, as well as functional, engineering and technological features are determined for the feeder in the tunneling machine. The development ways of the structural design solutions of the slider-crank mechanism in the mining machines are specified. The analysis for balancing of the mechanism on an elastic foundation with special pendulums attached to the crankshaft is done. The calculations to justify balancing using the pendulum are done. Modeling of the slider-crank mechanism is realized.
Highlights
The park of the tunneling machines in the coal industry is amounted to about 400 units
The hydraulic drives of the stroke and feeder allow operating in the flood places
The chain-andflight conveyor of the machine with the swinging tail section is capable of loading the rock mass in any mine transportation vehicle
Summary
The park of the tunneling machines in the coal industry is amounted to about 400 units (half of them are located in Kuzbass). The possibility of the heading construction with the high quality side surfaces and soil allows significant improvement of the performance of the machine by volume reduction of the destructible mass and a significant volume reduction of backing. The hydraulic drives of the stroke and feeder allow operating in the flood places.
