Abstract

An auto releasing hook of the life raft is designed to solve the technical problem that it is not force-saving and secure enough to release the life raft to the water with the current manual hook device. The auto releasing hook contains a hook support and a hook. Install the hook to the hook support with an installation pin shaft and a position-limit pin shaft is positioned on the both sides of the installation pin shaft. The upper part of the hook is provided with a U-typed furrow and the lower part is provided with a hook body and a bolt hole. A pull handle is positioned over the installation pin shaft of the hook with a hinge shaft. Between one end of the pull shaft and the U-type furrow of the hook is connected a spring and rollers; the other end of the pull handle connects a cable; a position-limit pin shaft is positioned on one side of the pull handle hinge shaft; the other end of the cable is connected with the bolt. Flip the hook with the bolt and make the hook move to the position to hook and hoist the life raft. After hoisting of the life raft, pull the pull handle with the steel cable and make the hook in the position ready to release the hoisted object. The hook will auto be in a position to release after the life raft reaches the water. The utility model can auto release from object the hook hoists and make the releasing operation more force-saving and safer while is of simple structure and low cost.

Description

Liferaft automatic release hook

(1) technical field

The utility model relates to and being used on the large ship by hanging the automatic decoupling device of machinery dispensing liferaft to the sea, specifically a kind of liferaft automatic release hook.

(2) background technology

Large ship in the sea navigation will be applied to liferaft on the sea sometimes.In the prior art, use a kind of manual trip mechanism to finish this work usually.After loop wheel machine on the naval vessel hangs onto on the sea, open described manual trip mechanism with manual mode to liferaft by the crewman.Because the sea is of strong winds and high waves, this unhook mode is still laborsaving not enough, and is safe not enough.

(3) summary of the invention

At, the inadequately technical matters of safety still laborsaving not enough to the sea with above-mentioned manual trip mechanism dispensing liferaft, the applicant has done further improvement, provides a kind of operation more laborsaving, safer liferaft automatic release hook.

The technical solution of the utility model is as follows:

Liferaft automatic release hook is characterized in that comprising suspension hook frame and suspension hook, has pin shaft hole on the suspension hook, suspension hook is installed on the suspension hook frame with bearing pin is installed by described pin shaft hole, installs the spacing bearing pin of suspension hook respectively in the both sides of described installation bearing pin; The top of suspension hook has U-lag, and coupler body and pin hole are arranged at the bottom of suspension hook; On the suspension hook frame in described suspension hook install bearing pin above with hinge device one pull handle, between the U-lag on one end of pull handle and described suspension hook top by fabricated section sequence unit spring and roller, spacing bearing pin at a side device pull handle of described pull handle hinge, the other end connection cable of pull handle, the other end of hawser is connected with a latch.

Use the utility model to carry out hanging when operating of liferaft, the wirerope of hanging liferaft is put into suspension hook, pull latch, suspension hook is turned to hang the position, at this moment, the suspension hook top is spacing by the spacing bearing pin in left side, is withstood the right part of suspension hook U-lag by the roller of spring butt.After liferaft is lifted by crane, pulling and pull handle other end bonded assembly hawser, described roller is rolled left along the suspension hook U-lag, withstand the left part of suspension hook U-lag, be hung on suspension hook on owing to liferaft this moment, the elastic force moment that spring passes to suspension hook U-lag left part by roller is not enough to overcome the gravity of hanging of liferaft, is not enough to promote suspension hook and rotates.When the liferaft of hanging falls into the water surface, when the gravity that liferaft is hung was released, the elastic force moment that spring passes to suspension hook U-lag left part by roller promoted suspension hook and around it bearing pin rotation is installed, and the wirerope of hanging liferaft is automatically-unhooked from suspension hook.By above-mentioned hang and the unhook process as seen, the utility model is hung the wirerope of liferaft can be automatically-unhooked, the operation of breaking off relations is more laborsaving, safer.The utility model is simple in structure, low cost of manufacture.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described:

See Fig. 1, Fig. 2, the utility model comprises suspension hook frame 1 and suspension hook 2, have pin shaft hole on the suspension hook 2, suspension hook frame 1 has parallel left and right wallboard, the bottom of left and right wallboard has the groove of placing hanger rope, between the left and right wallboard in position, the top device axle of hanging of the present utility model, the installation bearing pin 3 of lower portion device suspension hook, pin shaft hole and installation bearing pin 3 by having on the suspension hook 2 are installed in suspension hook 2 between the left and right wallboard of suspension hook frame 1.Between the left and right wallboard of suspension hook frame, install the spacing bearing pin 8 and 7 of suspension hook respectively in the and arranged on left and right sides that bearing pin 3 is installed.See Fig. 5 and Fig. 2, the top of suspension hook 2 has U-lag 22, and coupler body 23 and pin hole 21 are arranged at the bottom of suspension hook 2.

See Fig. 2, above suspension hook installation bearing pin 3, installing a pull handle 5 between the left and right wallboard of suspension hook frame 1 with hinge 28, between the U-lag 22 on one end of pull handle 5 and described suspension hook top by fabricated section sequence unit spring 26 and roller 25, its concrete mounting structure is: an end of pull handle 5 has the sleeve 27 of one, device has the spring bracket 4 of sleeve in the sleeve 27, device spring 26 between the sleeve of sleeve 27 and spring bracket 4, the termination of spring bracket 4 pin shaft device roller 25, U-lag 22 butts on roller 25 and described suspension hook top.Between the left and right wallboard of suspension hook frame, install the spacing bearing pin 29 of pull handle on the right side of described pull handle hinge 28, the other end of pull handle 5 connects wirerope 6, sees Fig. 1, and the other end of wirerope 6 is connected with latch 9, device plug housing 10 on the wallboard of suspension hook frame, latch 9 inserts in the plug housing 10.

Working process of the present utility model: use the utility model to carry out hanging when operating of liferaft, see Fig. 1, Fig. 2, Fig. 5, the wirerope of hanging liferaft is put into the coupler body 23 of suspension hook 2, latch 9 is inserted in the pin hole 21 of suspension hook 2 bottoms, pull latch 9 left, make suspension hook turn to Fig. 1, the position of hanging shown in Figure 2, at this moment, the coupler body 23 of suspension hook 2 is spacing by the spacing bearing pin in left side 8, is withstood the right part 222 of suspension hook U-lag 22 by the roller 25 of spring 26 butts.After liferaft is lifted by crane, pulling and pull handle 5 other end bonded assembly wireropes 6, roller 25 is rolled left along the suspension hook U-lag, see Fig. 5, make roller 25 withstand the left part 221 of suspension hook U-lag, position as shown in Figure 3, it is called releasing position of the present utility model, be not enough to promote suspension hook 2 and rotate because liferaft is hung on the suspension hook, and the elastic force moment that spring passes to suspension hook U-lag left part by roller is not enough to overcome the gravity of hanging of liferaft this moment.When the liferaft of hanging falls into the water surface, the gravity that liferaft is hung is offset by buoyancy of water, spring 26 promotes suspension hook 2 around its installation bearing pin 3 anticlockwise rotations by the elastic force moment that roller 25 passes to suspension hook U-lag left part, spacing until the back 24 of suspension hook 2 by the spacing bearing pin in right side 7, its position as shown in Figure 4, be called unhook of the present utility model position, the wirerope of hanging liferaft is automatically-unhooked from suspension hook, and liferaft can be travelled at the water surface.
