    • The device comprises a linear actuator (1) comprises a fixed body (1a) connected to the stationary structure (2) and an extendible rod (1b) connected by means of a transmission (3a, 3b) to a mobile support (4) on which is fixed a bollard (5). Said transmission (3a, 3b) comprises a first flexible pull element (3a) and a second flexible pull element (3b) connected to a mobile drive element (7) connected to the mobile support (4). Said first and second flexible pull elements (3a, 3b) are linked to a distal end of the extendible rod (1b) and supported on respective first and second stationary pulleys (9, 10) installed in opposite sides with respect to said mobile drive element (7), the first and second flexible pull elements (3a, 3b) comprising several spans substantially parallel to a movement direction of the mobile support (4).
    • 该装置包括线性致动器(1),其包括连接到固定结构(2)的固定体(1a)和通过变速器(3a,3b)连接到移动支撑件(4)上的可伸展杆(1b) 固定了一个护柱(5)。 所述变速器(3a,3b)包括连接到连接到移动支撑件(4)的移动驱动元件(7)的第一柔性牵引元件(3a)和第二柔性牵引元件(3b)。 所述第一和第二柔性拉动元件(3a,3b)连接到所述可延伸杆(1b)的远端并且被支撑在相对于所述移动驱动元件相对侧安装的相应的第一和第二固定滑轮(9,10)上 (7),所述第一和第二柔性拉动元件(3a,3b)包括基本上平行于所述移动支撑件(4)的移动方向的多个跨度。
