A Z-shaped
layout fixed-length dual-
rope-grouped closed force
system capture and
recovery net
system, comprising: a capture and interception
assembly, which comprises a
rope group a (1), a
rope group b (2), a rope group c (3) and a rope group d (4), wherein the rope group a (1), the rope group b (2), the rope group c (3) and the rope group d (4) are each wound around two movable
pulley blocks (5), the two movable
pulley blocks (5) being arranged opposite each other, and the rope group a (1) between the two movable
pulley blocks (5) is an interception section a (6), the rope group b (2) between the two movable pulley blocks (5) is an interception section b (7), the rope group c (3) between the two movable pulley blocks (5) is an interception section c (8), and the rope group d (4) between the two movable pulley blocks (5) is an interception section d (9); and a support
assembly which comprises four stand columns (10), wherein the four stand columns (10) are fixedly connected to a base (11), a guide rail (12) is fixedly connected between every two adjacent stand columns (10), the movable pulley blocks (5) are slidably connected to the guide rails (12), and are in transmission connection with a traction device (15), a plurality of fixed pulleys (13) are provided on the stand columns (10), and the rope group a (1), the rope group b (2), the rope group c (3) and the rope group c (4) are each wound around a different fixed pulley (13). The capture and
recovery net
system can effectively reduce the length of the rope group a (1), the length of the rope group b (2), the length of the rope group c (3) and the length of the rope group d (4), and can also reduce the force and work of the traction device.
