Abstract:
A protective arrangement for hydraulic actuators of an underground shield from dynamic overload with a mechanical rotary absorber. It comprises a hydraulic actuator (103) mountable to the base (102) of the underground shield, to which there is connected a rotary device (110) for taking over and dissipating the energy of rocks falling on the hood (101), wherein the device (110) for taking over and dissipating energy comprises a ram element (1) mounted to the actuator (103), slidably coupled by means of ram guides (14) with side walls of a base plate (13) mountable to the hood (101), which cooperates with at least two serially connected racks (2, 3, 4) mounted slidably on a runner (15) and driving toothed wheels (9, 9a, 9b, 9c) of the kinetic energy rotary accumulators (10, 11, 12), wherein distances (5, 6, 7) are created between the ram element (1) and the first rack (2), as well as between the particular racks (2, 3, 4), said distances enabling the displacement of the ram element (1 ) in relation to racks (2, 3, 4), as well as the displacement of these racks (2, 3, 4) in relation to one another, such as to enable the moving ram element (1) to pass the kinetic energy of the translational movement to the kinetic energy rotary accumulators (10, 11, 12) in order to transform it to the kinetic energy of rotational movement.
