Safety and rescue device for mountain conveyor belt

A combination of a safety device (1) and a conveyor belt unit (2), comprising:

• a transporting band (2d);
• a conveyor belt unit box (2a) with two curbs (2b, 2c) covering respective lateral edges of the transporting band (2d);
• and
• a chest (3) forming a safety well, the chest (3) comprising i) a sliding flap (4), ii) two lateral guides (5a, 5b), the sliding flap (4) slidable in the two lateral guides (5a, 5b) between an open position and a closed position, iii) a pressure-sensitive frontal blade (7) integral with the sliding flap (4), and iv) a motorized winding unit (10) arranged to move the sliding flap (4) and the frontal blade (7) between the closed position and the open position, wherein,
• the frontal blade (7) is operative to detect pressure and thereupon have the motorized winding tube move the flap (4) from the closed position to the open position,
• in the closed position, a longitudinal edge of the frontal blade (7) is in a vicinity of an end of the transporting band (2d), the frontal blade (7) and an immediately adjoining first end portion of the flap (4) are in a generally horizontal orientation, and an opposite second end portion of the flap is in a generally vertical orientation with the second end portion engaged with the motorized winding tube (10), and
• in the open position, the longitudinal edge of the frontal blade (7) and the immediately adjoining first end portion of the flap (4) are located at a spaced apart distance from the end of the transporting band (2d) so as to define an opening into the safety well, the opening delimited by the longitudinal edge of the frontal blade (7), the two lateral guides (5a, 5b), and the end of the transporting band (2d).
