Abstract

The utility model patent discloses a kind of self-adjusting positioning and locking suspension hook for suspender, especially suitable for all kinds of floating bodies of marine ship folding and unfolding, suspension hook is mounted on the seat board of suspender lower end, and the mechanism is containing coupler body, hook seat, bolt block, single-acting bolt block oil cylinder, reset spring etc.；Suspension hook has capture function, it can lock or disengage object, to recycle or release object, the hook seat tool of suspension hook has positioning guiding structure end to have default slot, this structure can be in contact being directed at slot after suspension hook contact floating body hanging ring with coupler body shift fork, can reduce impact between the two, to when not yet clamping floating body hanging ring, enable floating body hanging ring slowly as shift fork moves, damage towed body will not, high degree of automation.

Description

A kind of self-adjusting positioning and locking suspension hook for suspender

Technical field

The utility model patent is related to marine ship floating body folding and unfolding technical field more particularly to a kind of suspension hook for suspender Technical field.

Background technique

On ships widely used floating body equipment folding and unfolding suspender be by boat-carrying loop wheel machine by rope, hook system it is solid into Row realizes, during floating body folding and unfolding rope, hook be all be that artificial binding is completed mostly admittedly, folding and unfolding process is by marine environment Etc. external conditions limitation, so that marine folding and unfolding Job Operations difficulty is larger, manipulation process to the danger of equipment and personnel bring because The problems such as element is more, and folding and unfolding process is complicated drastically influences the operating efficiency of marine float folding and unfolding and the safety of operator.

Summary of the invention

It is hung in view of the above-mentioned problems, the utility model patent is designed to provide a kind of self-adjusting positioning and locking for suspender Hook, to solve the problems of the prior art.

To achieve the goals above, the technical solution of the utility model patent is as follows:

A kind of self-adjusting positioning and locking suspension hook for suspender, including with the matched hook seat of floating body hanging ring, the hook seat packet Symmetrical two clevis half seats are included, the hook seat, which is equipped with, can satisfy the reserved of the required space of floating body hanging ring movement locking Slot is respectively arranged with the coupler body being fixedly connected by pin shaft on the clevis half seat of the left and right two, is provided on the coupler body Block, lower stopper and shift fork, the upper stopper define a bolt space, the bolt space with inserting above coupler body is set Pin block adaptation, the lower stopper are adapted to floating body hanging ring, and the shift fork is arranged in the middle part of coupler body and is oppositely arranged to form cross knot Structure.

A kind of preferred embodiment of the utility model patent, the coupler body being arranged on hook seat are left and right symmetrically arranged.

A kind of preferred embodiment of the utility model patent, the coupler body upper stopper and bolt block contact side are three sections of profiles Composition, the arc surface including the initial segment, the plane of interlude, the inclined surface of terminal section.

A kind of preferred embodiment of the utility model patent, coupler body lower end block and floating body hanging ring contact side are by cambered surface With one section of plane set of transitions at.

A kind of preferred embodiment of the utility model patent, the bolt block are located above coupler body between block, in bolt block End is equipped with reseting pressuring spring, and the bolt block lower end is adapted with the bolt space Internal periphery that overhead gage defines.

Utility model has the advantages that connecting being directed at slot after suspension hook contact floating body hanging ring with coupler body shift fork Touching, can reduce impact between the two, thus enable floating body hanging ring slowly as shift fork moves when not yet clamping floating body hanging ring, Damage towed body will not.Once floating body hanging ring enters coupler body and pushes coupler body rotation certain by suspender gravity or towed body buoyancy After angle, that is, it can trigger locking action, hanging ring hooked, high degree of automation.

Specific embodiment

In order to be apparent to the technological means and implementation of the utility model patent, combined with specific embodiments below into One step illustrates the utility model patent.

Referring to Fig. 1-4, a kind of self-adjusting positioning and locking suspension hook for suspender of the utility model patent, including with floating body The matched hook seat 10 of hanging ring 2,10 lower part of hook seat are that eight words are oriented to shape, and hook seat includes symmetrical two clevis half seats 1, hook seat It is equipped with the reserved slot 11 in space needed for can satisfy the movement locking of floating body hanging ring 2, is set respectively on the two clevis half seats 1 in left and right Be equipped with the coupler body 3 being fixedly connected by pin shaft 5, and coupler body 3 is left and right symmetrically arranged, be provided on the coupler body 3 upper stopper 31, under Block 32 and shift fork 33, wherein upper stopper 31 and bolt block 4 contact side and form for three sections of profiles, the circular arc including the initial segment Face 34, the plane 35 of interlude, the inclined surface 36 of terminal section, lower stopper 32 are adapted to 2 with floating body hanging ring, and touch side by cambered surface 37 It is formed with one section of plane changeover portion 38, the shift fork 33 is arranged in the middle part of coupler body and is oppositely arranged to form intersection construction；Floating body is hung Ring 2 under the guiding role of hook seat 10 enter slot after start contact coupler body 3 on shift fork 33, suspension hook entirety gravity about Two rotations of shift fork 33 drive coupler body 3 to rotate under beam, so that the upper and lower block of coupler body 3 is made to turn to latched position or open position, As Fig. 3 hanging ring pushes shown in coupler body schematic diagram.

In the present invention, the upper stopper 3 defines a bolt space 30, and bolt space 30 and setting are on coupler body The bolt block 4 of side is adapted to, and can play the role of limition orientation to bolt block 4, and after coupler body 3 turns an angle, bolt block 4 is pushed up The inclined-plane guide frame at end enters immediately in the bolt space 30 that two coupler bodies, 3 upper stopper defines, and pushes under the effect of reset spring 6 Bolt block 4 moves downward in the inclined surface 36 up to entering 3 upper stopper terminal section of coupler body, while bolt block lower end and overhead gage circle The bolt space Internal periphery made is adapted；Bolt block 4 and coupler body 3 reach structure under the mounting structure constraint of hook seat 10 at this time Braking condition is tightened, coupler body 3 and 4 relative displacement of bolt block remain unchanged, and reach locking purpose.Such as need to open suspension hook locking shape State then needs to operate bolt block oil cylinder 7 and pulls pin, and bolt block 4 is made to exit 3 block range of coupler body, then coupler body 3 can be in reset spring 6 And opened under object gravity, block closes up, and bolt block oil cylinder 7 is set as single-acting type oil cylinder, after not operating, bolt block 4 Block is pushed down under the effect of reset spring 6, is returned to the bolt block opening state of Fig. 4 at this time, preparation is lifted by crane next time.It pulls out Pin separately matches manual-operated emergent drag-line, when hydraulic system failure, can the movement of manual actuation bolt block 4 complete to pull pin movement, opening is hung Hook.
