Description

Release mooring hook with flexible latch hook device

Technical field

The utility model belongs to a kind of special tool that uses on the harbour, in particular, relates in particular to a kind of release mooring hook with flexible latch hook device.

Background technology

The tradition petrochemical pier at the heaving pile of boats and ships, take off cable and mostly adopt mooring dolphin, namely by warping winch or directly be enclosed within on the mooring dolphin after manually hawser being pulled on bank, boats and ships leave front by manually stay cord being appeared on the stage from mooring dolphin, operation is very difficult because hawser is very heavy, not only increases labour intensity but also meets accident easily.The domestic quick releasing hook that multiple automatically stranded cable and automatic trip cable laying rope have occurred afterwards, when boats and ships pull in to shore rapidly heaving pile, take off cable, but each member of existing release mooring hook inside tends to occur rigid contact at heaving pile, when taking off cable, even the generation spark, may produce serious consequence at petrochemical pier.

Summary of the invention

The utility model provides a kind of release mooring hook with flexible latch hook device, and there is the problem of rigid contact in inner each member in the release mooring hook course of work that exists in the prior art in order to solve, thereby has reduced the risk that exists when petrochemical pier uses.

The utility model is to realize by following technical scheme:

Release mooring hook with flexible latch hook device, comprise grasp and hook housing soldering member, grasp and hook housing soldering member are hinged by connecting axle, the inside of hook housing soldering member is provided with locking fork hook device, pressure hook block, unhook tommy bar and hook housing connector, and locking fork hook device, pressure hook block, unhook tommy bar are hinged with the hook housing soldering member respectively; Unhook tommy bar one side of hook housing soldering member unhook tommy bar safety device is installed, grasp Self-resetting elastic supporting member for supporting optical member is installed on the hook housing connector by bolt, locking fork hook device is connected with the pressure hook block by the flexible locking extension spring, the contact position of pressure hook block rear end face and hook housing soldering member is provided with pressure hook block bolster, and the hook housing connector is provided with the grasp bolster that resets.

Described pressure hook block bolster and the grasp bolster that resets is made by the block rubber with steel disc, and this kind material can slow down the wearing and tearing of block rubber, prolongs its application life.

Compared with prior art, the beneficial effects of the utility model are: the utility model not only can carry out heaving pile safely and fast and take off cable work, avoided at heaving pile, taken off the accident unhook phenomenon that exists in the cable process, and avoided at work because the rigid contact of inner each member of release mooring hook produces the risk of bringing when spark may use to petrochemical pier, and can automatically reset after the grasp unhook, need not manually to pull.

Fig. 3 is the schematic diagram that takes off the cable state of the present utility model.

Among the figure, 1, hawser; 2, grasp; 3, hook housing soldering member; 4, locking fork hook device; 5, pressure hook block; 6, unhook tommy bar; 7, unhook tommy bar safety device; 8, flexible locking extension spring; 9, butt hook bolt; 10, pressure hook block bolster; 11, the grasp bolster that resets; 12, grasp Self-resetting elastic supporting member for supporting optical member; 13, hook housing connector; 14, connecting axle.

The specific embodiment

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

As shown in Figure 1, the utility model comprises grasp 2 and hook housing soldering member 3, grasp 2 and hook housing soldering member 3 are hinged by connecting axle 14, the inside of hook housing soldering member 3 is provided with locking fork hook device 4, pressure hook block 5, unhook tommy bar 6 and hook housing connector 13, and locking fork hook device 4, pressure hook block 5, unhook tommy bar 6 are hinged with hook housing soldering member 3 respectively; Unhook tommy bar 6 one sides of hook housing soldering member 3 unhook tommy bar safety device 7 is installed, grasp Self-resetting elastic supporting member for supporting optical member 12 is installed on the hook housing connector 13 by bolt, locking fork hook device 4 is connected with pressure hook block 5 by flexible locking extension spring 8, the contact position of pressure hook block 5 rear end faces and hook housing soldering member 3 is provided with pressure hook block bolster 10, hook housing connector 13 is provided with the grasp bolster 11 that resets, described pressure hook block bolster 10 and the grasp bolster 11 that resets is made by the block rubber with steel disc, this kind material can slow down the wearing and tearing of block rubber, prolongs its application life.

Need when as shown in Figure 2, the utility model uses to be fixed on the special equipment that harbour is used for the heaving pile release mooring hook by butt hook bolt 9.When the heaving pile state, grasp 2 automatically resets under the effect of deadweight and grasp Self-resetting elastic supporting member for supporting optical member 12, then the handle of manually pulling gently pressure hook block 5 is pressed into the idler wheel bottom of locking fork hook device 4 with the front end of pressure hook block 5, and the roller of latch hook fork hook device 4 is that tangent line contacts with pressure hook block front end pressure head; The rear end face of pressure hook block 5 compresses the afterbody of grasp 2, flexible locking extension spring 8 connects the bar linkage structure of pressure hook block 5 and the chain interaction of locking fork hook device 4 formations, the end hook tail must turn over behind its grasp 2 under the pulling force effect of grasp 2 at hawser 1, it is locked with the front end pressure head of pressure hook block 5 that flexible locking extension spring this moment 8 drives locking fork hook device 4, for preventing that accident is run into the situation that hawser 1 accidental occurs unhook tommy bar 6 in the course of the work, backing pin in the unhook tommy bar safety device 7 need to be pushed in the backing pin hole of hook housing soldering member 3 unhook tommy bar 6 is blocked, in the heaving pile process, grasp 2 and the grasp bolster 11 that resets contacts, can prevent that grasp 2 from directly producing spark with hook housing connector 13 rigid contacts, thereby make boats and ships when petrochemical pier is stopped, be in safe heaving pile state.

As shown in Figure 3, when boats and ships need offshore, hawser must be thrown off, only need this moment movable unhook tommy bar safety device 7 that backing pin is skidded off in the backing pin hole of hook housing soldering member 3, unhook tommy bar 6 contacts for point with locking fork hook device 4, pull gently unhook tommy bar 6 with declutcher control lever movably, making it drive locking fork hook device 4 by fulcrum rotates, can make this moment the front end of pressure hook block 5 break away from the roller release pressure hook block 5 of locking fork hook device 4, pressure hook block 5 overturns under the effect of flexible locking extension spring 8 at this moment, the rear end pressure surface of pressure hook block 5 leaves grasp 2, realizes the unhook of hawser thereby grasp 2 overturns under the effect of hawser.Be that hard collisions occur for rear end pressure surface and the hook housing soldering member 3 prevent pressure hook block 5, in both contact positions with the fixing pressure hook block bolster 10 of bolt, realization flexible impact; After being installed in the rubber components generation flexible contact on the elastomeric element on grasp 2 and the grasp Self-resetting elastic supporting member for supporting optical member 12, under the effect of grasp Self-resetting elastic supporting member for supporting optical member 12, grasp 2 is resetted, when grasp 2 resets and on the hook housing connector 13 with the fixing grasp of bolt bolster 11 flexible impacts that reset, thereby avoided grasp 2 to contact with the rigid of hook housing connector 13.

Take off in the cable process at whole heaving pile, Buffer Unit everywhere is so that each member of release mooring hook is realized flexible contact, and is both without hard collision also noiseless, very soft in the course of work, is particularly useful for heaving pile that petrochemical pier carries out boats and ships, takes off cable.
