[0013] Figure 2 It is the structure schematic diagram of the double -end bundle rope mechanism on the board cover. PREFERRED EMBODIMENT

[0014] The utility model will be further explained in connection with the drawings.

[0015] As Figure 1 The utility model discloses a rescue boat crane release anti -swing device, including boat crane 1, the head of the crane arm 10 of boat crane 1 is provided with head trolley 2 and board cover 3, and the board cover 3 is hinged to be connected with the frame of head trolley 2, the lower end of board cover 3 is connected with bundle rope cylinder 4, and the ring plate frame 5 on the bottom of bundle rope cylinder 4 is hung with bundle rope board 7 through the pulling mechanism 6, the guide rod 8 of vertical slip is connected on bundle rope board 7 and penetrates the ring plate frame 5, and bundle rope board 7 keeps coaxial through the radial location of guide rod 8 and bundle rope cylinder 4, and the rope 9 of boat crane 1 passes bundle rope cylinder 4, bundle rope board 7 in proper order, and bundle rope board 7 is vertically displaced through the release and pulling of pulling mechanism 6, and forms the double -end bundle rope mechanism of adjustable vertical spacing with bundle rope cylinder 4. The utility model discloses the setting bundle rope cylinder 4 and bundle rope board 7 on the hanging rope section of boat crane 1, and form double -end bundle rope state, and bundle rope board 7 can be according to the bundle rope progress synchronous motion of moving down, guarantee the effectiveness and timeliness of the lower end bundle rope, thereby effectively prevent the large swing of the release of the rescue boat, improve the safety and efficiency of the boat.
