Detailed description of the invention
By best embodiment, the present invention is described in detail below.
As shown in Figure 1, sea-going parking garage large springboard slip-off preventing self-locking device, comprises base 1, stern transom plate 3, spring stop 9 and front shrouding 15 are vertically fixed on base 1, stern transom plate 3 is fixed on device low order end, and front shrouding 15 is fixed on device high order end, and spring stop 9 is fixed in the middle of device; Base 1 is provided with electromagnet 2, electromagnet 2 right-hand member is fixedly connected with stern transom plate 3; Be provided with screw mandrel connecting pin 5 on the left of electromagnet 2, screw mandrel connecting pin 5 connects the iron core of electromagnet 2; Swirl pin 17 is horizontally placed in the hole on front shrouding 15, swirl pin 17 right-hand member is connected with drive lead screw 4, and drive lead screw 4 right-hand member connection wire rod connecting pin 5, is set with 7 outside drive lead screw 4, retracing spring 7 one end withstands on spring stop 9, and the other end of retracing spring 7 withstands on swirl pin 17.
Also comprise by manual lock dog 10, manual draw bar 11, revolve the manual draw bar assembly locked handle component 12 and form, manual lock dog 10 bottom is fixed on 4 right-hand members, manual lock dog 10 top also fixed manual pull bar 11, manual draw bar 11 is horizontally placed on above electromagnet 2, one end of manual draw bar 11 reaches through stern transom plate 3 that device is outer to be locked handle component 12 and be connected with revolving, and the other end of manual draw bar 11 passes the left side that spring stop 9 extend into device body.
Front shrouding 15 is installed in the hole of swirl pin 17 and is fixed with stub bearing 14, between stub bearing 14 and swirl pin 17, be provided with dust ring 16.
Stub bearing 14 is provided with lubricating oil inlet 8.
Drive lead screw 4 left end is set with screw mandrel lock sleeve 6, and the left part of retracing spring 7 is set in outside screw mandrel lock sleeve 6.
The suction of electromagnet 2 is greater than the elastic force of retracing spring 7.
After slip-off preventing self-locking device installed by the large springboard of ferry boat, when boats and ships lifting springboard, navigating mate rotary switc is to " liter " position, solenoid valves, oil cylinder oil inlet is made to pull springboard to rise by steel rope, after the hanger on springboard touches secondary bearing pin, make stub axial magnetic iron direction insert hanger hole, complete the locking of springboard.Glide when springboard and act on bearing pin by hanger, such bearing pin just plays the effect of safety plug.
When ferry boat needs landing springboard, navigating mate only needs rotary switc to " falling " position.Have downslide phenomenon because springboard hydraulic efficiency pressure system in use can produce micro-leakage to making springboard, cause springboard weight to act in safety pin shaft, now electromagnet pulls out motionless pivot pin.Therefore this device by circuit control part first springboard is upwards risen automatically winch to pivot pin be in quick condition time, in device electromagnet energising adhesive, make bearing pin extract hanger hole, now springboard starts down maneuver.When bearing pin can not insert hanger hole, electromagnet dead electricity, retracing spring makes bearing pin stretch out, and is blocked the shift position of stub axle when bearing pin position is paid in arrival by pair bearing pin, so completes one action circulation.
Last it is noted that obviously, above-described embodiment is only for example of the present invention is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection scope of the present invention.
