PIT HEAD LANDING WITH CAR INTERCHANGE Russian patent published in 2008 - IPC E21F13/00 B61J3/00 B66B17/00 B65G69/00 

FIELD: mining.

SUBSTANCE: invention refers to mechanisation of car interchange in the pit head during cage winding. The landing is provided with the first rail tracks laid on the pit head floor, adjoining to the shaft and inclined toward the car roll out side and the second inclined rail tracks adjacent the car dumper laid parallel to the first inclined rail tracks, car receiving platforms and additional rail tracks oriented perpendicular to the said rail tracks. According to the invention each additional rail track is secured on a frame, which is hinged to the pit head floor and can be turned in the vertical plane, one of the free ends of the frame being connected cinematically with the actuating cylinder. Both free ends of the frame with the rails secured are bent upwards and the length of each bent part of the frame is selected so as to accommodate the platform with the car. The frame hinge under the first additional rail track is located in the middle part of the frame and the frame hinge under the second rail track is shifted from the middle part of the frame toward the shaft. The car can roll by gravity over the additional rail tracks. The invention enables to simplify the design of the landing, automation of control of mechanisation aids used for car interchange and to increase reliability of operation.

EFFECT: simplification of the design of the landing and automation of control of mechanical aids used for car interchange, increase of reliability of operation.
