Abstract

The utility model discloses a dual-purpose release hook which not only can be used as a manual release hook of a rescue boat, but also as an automatic release hook of a lifeboat. The dual-purpose release hook is mainly used for a lifting machine on a large ship to send the rescue boat or the lifeboat down to a sea surface, and comprises a hook frame and a hook, wherein, the hook is arranged on the hook frame by a first pin passing through a pin hole on the hook. The dual-purpose release hook is characterized in that above the hook, a joystick is arranged on the hook frame by a second pin; when the hook is positioned at a weight lifting position, the head of the joystick hooks a limiting surface on the hook, one end of a torsion spring which is sleeved on the second pin is connected with a loose axle which is movably arranged on the joystick, while the other end is pressed at the position of the limiting hook of the hook. The dual-purpose release hook of the utility model ensures that the lifting machine on the large ship does not need to be equipped with two sets of release hooks, thus reducing use cost; and moreover, the dual-purpose release hook of the utility model has simple structure and convenient operation.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

As shown in Figure 1, 2, 3, the utility model comprises suspension hook frame 1 and suspension hook 2, first bearing pin 4 is installed in suspension hook 2 on the suspension hook frame 2 by the pin shaft hole on the suspension hook 2, in the present embodiment, device has axle sleeve 14 between the pin shaft hole on the suspension hook 2 and first bearing pin, axle sleeve 14 can be made also commercially available oilless bushing by metallic materials such as copper or powdered metallurgical material.Above suspension hook 2, joystick 3 is installed on the suspension hook frame 1 by second bearing pin 5.Suspension hook frame 1 comprises left side plate 101,102, they are installed together by the nut of hanging on axle 103, nut 105 and first bearing pin 4 107, hang the axle 103 on device roller 104 is arranged, holding screw 106 is installed in to be hung between axle 103 and the nut 105, holding screw 108 is installed between first bearing pin 4 and the nut 107, prevents in the use nut 105 and nut 107 gets loose and suspension hook frame 1 is got loose.When suspension hook 2 is in the lift heavy position (state shown in Fig. 1,2,4), the head of joystick 3 hooks the confined planes 201 on the suspension hook 2, in the present embodiment, suspension hook 2 is provided with a rectangular notch 202, and the head of joystick 3 passes above-mentioned notch 202 and hooks confined planes 201 on the suspension hook 2.An end that is sleeved on the torsion spring 11 on second bearing pin 5 inserts in the hole of the movable axis 12 of head on joystick 3, can relatively rotate between movable axis 12 and the joystick 3, and the other end is pressed in positive stop hook 203 places of suspension hook 2.Spacing bearing pin 7 in joystick 3 belows is installed on the suspension hook frame 1, block mechanism 6 devices are at suspension hook frame 1 and suspension hook 2 head opposite sides, block suspension hook 2, in the present embodiment, block mechanism 6 comprises block 601, and on suspension hook frame 1, torsion spring 603 1 ends that are sleeved on the bearing pin 602 insert in the hole of the limit shaft 604 of device on the suspension hook frame by bearing pin 602 devices for it, the other end is fitted in the notch of block 601, and an end of block 601 is pressed against on the limit shaft 604.The handle end of suspension hook 2 and joystick 3 device respectively has drag-line 9,10.The two sides of joystick 3 have two location notch holes 301,302 respectively, device has ball holding screw 8 respectively on the relevant position of two side plates 101 of

suspension hook frame

1 and 102, device has jam nut 13 on the ball holding screw 8, jam nut 13 is fastened on the inboard of suspension hook frame side plate 101,102, works to prevent that ball holding screw 8 from getting loose.When ball holding screw 8 was aimed on the joysticks 3 slotted eye 302, suspension hook 2 was in the lock state, can be at suspension hook 2 loaded weights (Fig. 1,2,4); When ball holding screw 8 was aimed on the joysticks 3 slotted eye 301, joystick 3 was opened, and suspension hook 2 is in automatic or manual release position (Fig. 3,5,6).

Working process of the present utility model: when the utility model is in release position (Fig. 6), the head that the handle of suspension hook 2 upwards is pushed into suspension hook 2 is blocked by block 601, the handle of joystick 3 upwards is pushed into its head hooks confined planes 201 (state shown in Fig. 1,2,4) on the suspension hook 2, at this moment, the ball of ball holding screw 8 ends is aimed at the location notch hole 302 of joystick 3 sides, the wirerope of hanging rescue craft or liferaft can be hung into suspension hook 2, block 601 can prevent that wirerope from skidding off from suspension hook 2.When loop wheel machine hangs the large ship deck when beginning to transfer with rescue craft or liferaft, downwards pulling drag-line 10 head that makes joystick 3 is from the confined planes 201 on the suspension hook 2 spin off (as Fig. 5), at this moment, the ball of ball holding screw 8 ends is aimed at the location notch hole 301 of joystick 3 sides, because on the suspension hook 2 load is arranged, suspension hook 2 can not opened release.When rescue craft arrives the water surface, because rescue craft is used to succour the personnel on other the naval vessel, large ship still is in operational configuration, the pulling force that suspension hook 2 still has the relative motion of water and rescue craft to produce, the elastic force of torsion spring 11 is not enough to suspension hook 2 places are opened automatically, at this moment, spur drag-line 9 downwards and make the wirerope of hanging rescue craft break away from suspension hook 2 (Fig. 3,6), be released on the water surface; When liferaft arrived the water surface, because liferaft is used for escape, large ship was in halted state, no longer includes load on the suspension hook 2, and the elastic force of torsion spring 11 is opened suspension hook 2 (Fig. 3,6), and liferaft is automatically released on the water surface.
