The concrete structure of the present invention and effect are as follows:
As depicted in figs. 1 and 2, pin inserting-pulling device by Handleset (include end cap 5, spring 6, sliding sleeve 7, connecting rod 10, guide cylinder 9, rise revoke 4 and bearing 11 form).Whole device is typically mounted at the top of submersible, is positioned on the Water Plane of submersible.When Handleset is at the D of position and when locking, rising and revoke in the cavity being reduced to guide cylinder 9 in 4, now the set cable passage between 2 two otic placodes of submersible hoisting structure is opened, and facilitates frogman that hanger rope 3 is sent into set cable passage.Once playing hanger rope 3 to be in place, rapid pull-up sliding sleeve 7 unlocks, and by position D, handle is swung to position E, it is ensured that rises and revokes 4 and passed hanger rope 3, then puts down sliding sleeve 7 locked.
One, Handleset
As it is shown in figure 5, Handleset is made up of end cap 5, spring 6, sliding sleeve 7 and connecting rod 10, its Main Function is to have driven to revoke 4 stretch out and bounce back, and in position D and two critical localisations lockings of position E, principal character is as follows:
(1) as it is shown in figure 5, Handleset is the stud prominent by end cap 5 end face and the threaded engagement of connecting rod 10, spring 6 is compressed in the shoulder hole of the embedded ring-shaped groove of end cap 5 and sliding sleeve 7 head so that sliding sleeve 7 can tightly against the outer surface guiding cylinder 9；
(2) end cap 5 has an embedded ring-shaped groove, and end face highlights one section of stud.The surfaces externally and internally of embedded ring-shaped groove can fit tightly with spring 6 surfaces externally and internally, effectively limits the irregular deformation of spring 6, it is ensured that it compresses in the space of design；
(3) effect that spring 6 is main is compression, it is ensured that in limited deformation range, it is possible to have enough elastic force make sliding sleeve 7 can tightly against guide cylinder 9 surface embedded groove in-, it is ensured that the reliability of locking；
(4) shoulder hole of sliding sleeve 7 inner chamber is divided into two sections, and front sector hole coordinates with spring 6, with the compression stroke that the embedded ring-shaped groove of end cap 5 constitutes spring 6.Rear sector hole coordinates with connecting rod 10 so that the prominent stud of inner ring and end cap 5 that connecting rod 10 can sequentially pass through this hole and spring 6 screws.Additionally, the end of sliding sleeve 7 has individual angle of chamfer, this angle constitutes wedge-like engagement with guiding cylinder 9 surface groove, has the most just pinned the current location of connecting rod 10.
(5) connecting rod 10 is the important component part of whole device, and its pendulum angle has directly determined the moving range revoking 4, and cleverly rotation has been converted into linear motion, it is achieved that the Core Feature of device.
(6) as shown in Figure 6, connecting rod 10 is made up of cylindrical section 1001 and flat part 1003, and cylindrical section 1001 is the active segment of sliding sleeve 7, is combined by spring 6 by screw thread with end cap 5 simultaneously.Flat part 1003, during swinging, is shown in Fig. 4 at the loose slot guiding cylinder all the time and rises to revoke in 4 end grooves and move, and the motion of three parts coordinates and ensure that and revoke 4 normally stretch just.
(7) as shown in Figure 6, connecting rod 10 flat part 1003 be designed with mounting hole 1002, this hole limits connecting pin 8 and sees the range of activity of Fig. 3, it is ensured that the rotation of connecting rod 10 has been converted into when revoking 4 linear motion will not jam.
(8) as it is shown on figure 3, connecting pin 8 sequentially passes through revokes 4 penetrating mounting holes seeing Fig. 7 end and the mounting hole 1002 of connecting rod 10 flat part 1003, by cross revoke 4 and connecting rod 10 link together.
(9) as it is shown in fig. 7, rise and revoke 4 breech faces and be designed with two installing holes, it is simple to hex screw 14 screws through 8 two screwed holes of installing hole and connecting pin, be locked at revoke 4 run through interior.
(10) as in figure 2 it is shown, connecting rod 10 is shown in Fig. 8, the swing with the first bolt assembly 12 as the center of circle of the whole connecting rod 10 in being connected in bearing 11 loose slot by the first bolt assembly 12.
(11) as it is shown in fig. 7, be respectively arranged with an opening before and after bearing 11 to run through groove, groove above constitutes the wobble area of connecting rod 10, and another one open slot is directly fixed together by the second bolt assembly 13 with hoisting structure 2.
Two, cylinder and external connection are guided
Guiding cylinder 9 is the core component of whole device, is effectively guaranteed the functional realiey of device and outside installation, and main special medical treatment is as follows:
(1) as shown in Figure 4, the long waist shaped connecting rod loose slot 903 that runs through of cylinder 9 upper and lower surface is guided to limit the range of activity of connecting rod 10 so that connecting rod 10 and rise and revoke 4 and reach the limit of position D and position E simultaneously, it is ensured that to play hanger rope 3 bearing safety permissible.
(2) in guiding cylinder 9, mesopore has been effectively to revoke 4 to provide flexible activity space.
(3) extreme position that at cylinder 9 upper surface two, connecting rod 10 swings is guided to be designed with limited impression, can fit with the lozenges of sliding sleeve 7 end, make it stuck in groove, it is ensured that locking connecting rod 10, and then ensured that revoking 4 has reliably entangled hanger rope 3 in hoisting structure 2 overlaps cable passage.
(4) as it is shown on figure 3, guide cylinder 9 end flange 901 to be designed with five installing holes, it is fixed together with hoisting structure 2 by screw 14.
The operation principle of the present invention is as follows:
As in figure 2 it is shown, pin inserting-pulling device is arranged on the lifting framework at submersible top, on the Water Plane of submersible.When submersible is deployed troops on garrison duty, treating that submersible floats on the water surface, frogman drives canoe at the prominent hoisting structure in submersible top, unties the mooring rope and overlaps cable operation following (rise when laying to revoke and be in position E and locked):
Before a unties the mooring rope, the embedded groove of end cap 5 and sliding sleeve 7 embedded between spring 6 sliding sleeve 7 is tightly pressed against in the spacing groove of leading portion guiding cylinder 9, be so entirely limited the swing of connecting rod 10, and then locked and revoke 4.When untying the mooring rope, it is only necessary to by sliding sleeve 7 along connecting rod 10 upward sliding, spring 6 is made to bounce back, and then such as Fig. 3 in the spacing groove in front end of sliding sleeve 7 disengaging guiding cylinder 9, then rotate in an anti-clockwise direction connecting rod 10, has driven and has revoked 4 and be constantly moved to the left, and revokes 4 separate until rising with playing a hanger rope 3；
B, when connecting rod 10 swings to position D from position E, in just sliding sleeve 7 arrives the spacing groove in rear end guiding cylinder 9, is tightly pressed against in stopper slot under the effect of spring 6, and then limiting rod 10 swings, and then locked and revoke 4.
C is when submersible reclaims, a hanger rope 3 is put into the groove of hoisting structure 2, sliding sleeve 7 is moved up until leaving the spacing groove in rear end guiding cylinder 9 along connecting rod 10, then connecting rod 10 is swung to position E from position D, promote and revoked 4 and passed hanger rope 3, and by sliding sleeve 7 will be revoked at the E of position 4 locked, it is ensured that submersible lifts by crane safely.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention sees claim, within protection scope of the present invention, can make any type of amendment.
