Detailed description of the invention
As shown in Figures 1 to 6, the device connecting several joint under water fast that the present invention improves, comprises stiff end and mobile terminal; This stiff end mainly comprises male joint installing plate 8, collet axle 9, centre pilot sleeve 10, male joint 16, external orientation sleeve 20 and mounting plate 21; This mobile terminal mainly comprises ROV rotatable interface 1, power transmission shaft 2, Limit Bearing 3, transmission nut 4, female joint installing plate 7, packing ring 11, protective sleeve 12, collet 13, external orientation post 14, female joint 15, shear pin 25 and centre pilot post 17; Protective sleeve 12 sidewall of mobile terminal is provided with anti-deposit guard shield 22, and is provided with overload sleeve 24 between mobile terminal transmission nut 4 and collet 13; It is characterized in that, the protective sleeve 12 sidewall both sides of described mobile terminal are respectively equipped with one block of wing plate 23, and external orientation post 14 inserts end and is processed with guiding curved surface 28 (shown in Fig. 5).
As shown in Figures 1 to 6, the device connecting several joint under water fast that the present invention improves, wherein, described two blocks of wing plates 23 are the identical square plate body of two block lengths, and the two ends of this plate body side are respectively equipped with a chamfering, plate body are evenly provided with three screws 27; These two blocks of wing plates 23 deviate from the opposite side arranging chamfering and are welded on protective sleeve 12 outer wall both sides respectively and symmetrical in axle center; Six screws on two blocks of wing plates install a handle respectively for six bolts pass respectively.Described external orientation post 14 inserts end and is processed with guiding curved surface 28, this guiding curved surface 28 for radius be the arc surface of 10 to 15mm, this guiding curved surface has assembling guiding effect, and the insertion making mobile terminal is more reliable steady.
Below in conjunction with accompanying drawing, by specific embodiment, the present invention is described in detail.
The invention provides a kind of for and the device of multiple joint can be connected simultaneously under water, multiple joint can be the joint of hydraulic joint, electric connection, fibre-optic signal joint or conveying chemical liquid, and the operation of moving, connect and departing from can be carried out by ROV manipulator, this device can provide axial and circumferentially guiding for the exact connect ion of multiple joint, and enough large coupling mechanism force can be provided for the positiver sealing between multiple joint, its retaining mechanism adopts the locking mode of spring clip hair style, safe and reliable, be easy to operation.
The device connecting several joint under water fast that the present invention improves is made up of mobile terminal and stiff end.During use, this device has operating process such as connecting and extract, and wherein connection procedure is divided into two stages: insertion process and locking process.
Multifunctional quick joint insertion process under water: reality use process in, stiff end by mounting plate 21 by being bolted on the pedestal of seabed.The ROV rotatable interface 1 of mobile terminal caught by ROV manipulator, enter stiff end vertically, before this, power transmission shaft 2 must be rotated counterclockwise, collet 13 is moved forward vertically, collet 13 is pointed and is slided from center lead 17 internal boss, radially opens, and now anti-rotational boss 5 is positioned at protective sleeve 12 away from female joint installing plate side.First external orientation post 14 front end of mobile terminal enters in the external orientation sleeve 20 of stiff end, carry out rough axial location, the rear end of centre pilot post 17 and external orientation post 14 enters in centre pilot sleeve 10 and external orientation sleeve 20 respectively subsequently, realize accurate axial location, meanwhile, feather key 6 enters in the keyway of external orientation sleeve 20, plays the effect of circumferentially locating.Under effect that is axial and that circumferentially lead, 13 male joints and female joint are alignd respectively, when the Forward End Cap of collet axle 9 just touch collet 13 point time, ROV manipulator provides thrust, this thrust controls in the thrust range of manipulator, collet 13 is pointed and crosses collet axle 9 end cap, finger is held end cap and is axially being provided pretightning force like this.Now, the front end tag line 18 on feather key be inserted into bit-identify line 30 and align, such ROV is inserted into after bit-identify line 30 and front end tag line 18 align by observation, namely judges that mobile terminal has been inserted at axial direction and puts in place.When insertion puts in place, male joint 16 is not also inserted in female joint 15, but now both align.
The process of Multifunctional quick joint locking under water: after mobile terminal insertion puts in place, torque tool caught by ROV manipulator, torque tool is made accurately to be inserted on the square nut of power transmission shaft 2, (as shown in Figure 1) power transmission shaft 2 that turns clockwise then is started, because power transmission shaft 2 axially-movable is limited, therefore it can only produce rotary motion, transmission nut 4 and anti-rotational boss 5 connect, and anti-rotational boss 5 can only move axially in the stopper slot of protective sleeve 12, therefore transmission nut 4 will drive anti-rotational boss 5 and collet 13 to move to stiff end side vertically, in this process, collet 13 points constantly tension collet axle 9, make mobile terminal close to stiff end, female joint 15 is drawn close to male joint 16, male joint 16 is finally made to be inserted in female joint 15 completely, and provide an enough large coupling mechanism force to make between joint, to form sealing reliably, the complete conducting of joint, realize the transmission of signal.Meanwhile, the finger of collet 13 is to stiff end lateral movement, finally move to the inside of centre pilot post 17, finger is radially compressed, collet 13 pulling force pointed between collet axle 9 reaches maximum, under this reliable coupling mechanism force, the positiver sealing between 13 joints and conducting can be ensured.Meanwhile, anti-rotational boss 5, to stiff end lateral movement, finally moves to protective sleeve 12 axial groove rear end.Meanwhile, feather key 6 continues to insert in the keyway of external orientation sleeve 20, its front end tag line 18 last be locked to bit-identify line 29 and align, rear end tag line 19 be inserted into bit-identify line 30 and align, be locked to bit-identify line 29 align with front end tag line 18 when ROV observes, be inserted into after bit-identify line 30 aligns with rear end tag line 19, can judge now to lock and put in place, connect the end of job.
Multifunctional quick joint transfers to process under water: ROV manipulator provides pulling force to be extracted from collet 13 is pointed by elastic spindle 9, equally, this power should provide in weight range at manipulator, after extracting, axially external orientation post 14 is slowly being shifted out from external orientation sleeve 20, after centre pilot post 17 shifts out completely from stiff end, mobile terminal is placed on temporary set by manipulator or moves to that other is local.
Aforesaid operations process is prior art.
The present invention is respectively equipped with one block of wing plate in the protective sleeve sidewall both sides of mobile terminal, two blocks of wing plates are installed respectively a handle, picking and placeing of mobile terminal can be convenient to by handle, and two blocks of wing plates can play the effect supporting mobile terminal, not needing to configure the installation that bracing frame carrys out auxiliary moving end again, is that the installation operation of mobile terminal is more easy.The present invention is after outside lead insertion end is processed with guiding curved surface, and because external orientation post is less near fixing side diameter, even if therefore mobile terminal radial position during insertion has certain deviation, mobile terminal also reliably steadily can be inserted into stiff end.
The above, it is only the preferred embodiment of patent of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
