    • 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.
    • 一种地下屏蔽液压致动器与机械式旋转吸收器的动态过载保护装置。 其包括可安装到地下屏蔽的基座(102)的液压致动器(103),其连接有旋转装置(110),用于接收和消散掉在发动机罩(101)上的岩石的能量,其中, 用于接收和消耗能量的装置(110)包括安装到致动器(103)的冲击元件(1),其通过柱塞引导件(14)可滑动地联接,所述柱塞引导件具有可安装到罩的基板(13)的侧壁 101),其与可滑动地安装在转轮(15)上并且驱动动能旋转蓄能器(10,11)的齿轮(9,9a,9b,9c)的至少两个串联连接的机架(2,3,4)配合 ,12),其中在所述冲头元件(1)和所述第一齿条(2)之间以及所述特定齿条(2,3,4)之间产生距离(5,6,7),所述距离使得所述位移 (1)相对于机架(2,3,4)以及这些机架(2,3,4)相对于彼此的位移,以使得能够 移动的冲击元件(1)将平移运动的动能传递到动能旋转蓄能器(10,11,12),以将其转换成旋转运动的动能。
