The object of the present invention is to provide a kind of structure is simple, reasonable stress is easy to operate, and connection drift angle is larger, and connection is quasi-
Really, reliably, practicability is good, and the pull-type underwater connector device of the hook that secondary locking may be implemented, to realize that deep water drilling is set
Standby quick connection and disengaging, and prevent connector from undesirably falling off.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
As shown in figs 1-9, the present embodiment provides a kind of pull-type underwater quick connector arrangements of hook, including upper hub 1, direct acting
Driving device 2, linear guide apparatus 3, hook draw executive device 4, lower hub 5 and secondary locking device 6.
Wherein, direct acting driving device 2 include from top to bottom be fixedly connected sequentially support plate 201, linear drives structure and
Driving plate 203, support plate 201 are fixedly linked with upper hub 1, specifically the lower surface of the upper surface of support plate 201 and upper hub 1
It is connected, linear drives structure is to drive driving plate 203 to move up and down；Linear guide apparatus 3 includes from top to bottom successively fixing
Guide pipe 301, restraining plate 302 and the interfacing part 303 of connection, guide pipe 301 pass through driving plate 203 and carry out to driving plate 203
Guiding, restraining plate 302 are equipped with through-hole；It includes drag hook part 401 and hook 402 that hook, which draws executive device 4, and drag hook part 401 is fixed on
In driving plate 203, specifically 401 top of drag hook part has mounting base, the lower surface of the mounting base and the upper surface of driving plate 203
It is connected, extension hinged and with oblique outer upper side, through-hole draw executive device 4 for hook with drag hook part 401 on hook 402 top
It passes through, when extension is passed down through through-hole, outside and the structure mutual extrusion inside through-hole or through-hole of extension can make
The side oscillation outwardly of the lower end of hook 402, and from outside around the edge of lower hub；Lower hub 5 can be docked with interfacing part 303 or
Separation, lower hub 5 are equipped with the hole slot drawn for 402 hook of hook, which is preferably through slot；Secondary locking device 6 includes locking
203 top of driving plate, upper lock claw bottom are fixed in pawl pedestal 601, spring, upper lock claw 603 and lower lock claw 604, lower 604 lower end of lock claw
Seat 601 is fixed on 201 lower part of support plate, and the upper end of upper lock claw 603 and upper lock claw pedestal 601 are hinged, one end of spring and locking
Pawl pedestal 601 is fixedly connected, and the other end of spring is fixedly linked with upper lock claw 603, and upper lock claw 603 can be with lower 604 phase of lock claw
Mutually occlusion.
In use, under the action of linear drives structure, 203 downward actuation of driving plate drives entire hook to draw executive device 4
Downward actuation.Knot when hook 402 is passed down through the through-hole on restraining plate 302, inside the outside of extension and through-hole or through-hole
Structure mutual extrusion, can make the lower end side oscillation outwardly of hook 402, to make hook 402 from outside around lower hub 5, driving
Plate 203 continues downward actuation, so that hook 402 is passed completely through through-hole, hook 402 restores former angle, and pawl point is located in lower hub 5
The underface of hole slot.Linear drives structure acts driving plate 203 upwards at this time, and hook 402 hooks the hole slot in lower hub 5,
And drive lower hub 5 to complete to dock with interfacing part 303, simultaneously with this process, lower lock claw 604 move closer to lock claw 603 and with
Upper lock claw 603 abuts, and lower lock claw 604 continues to move up, the lower end of upper lock claw 603 in the case where the pressure that lower lock claw 604 provides is acted on around
The upper end articulated position turns an angle, until upper lock claw 603 and lower lock claw 604 are fully engaged against, upper lock claw 603 is in spring
Elastic force effect is lower to restore former angle, and linear drives structure no longer acts driving plate 203.The present embodiment is by filling secondary locking
Being mutually twisted for 6 upper lock claw 603 and lower lock claw 604 is set, the pull-type underwater quick connector arrangement meaning of hook can be effectively prevented
It frees outside, increases the reliability of connection, ensure that the lasting progress of production.Above-mentioned apparatus structure is simple, reasonable stress, operation
Simplicity, connection drift angle is larger, and connection is accurate, reliable, and practicability is good, is able to achieve the quick connection of deep water drilling-production equipment and is detached from.
In the present embodiment, the type of spring can be selected according to actual needs, and spring is Rigid Projectiles in the present embodiment
