Description
Technical field
The utility model relates to a kind of cover plate pinch device, particularly relates to the pinch device of a boats and ships scuttle cover or oil tank hatchcover.
Background technology
Scuttle cover on boats and ships and oil tank hatchcover, the sealing of its lid are after being compressed by the rubber strip of cover plate and coaming plate, lean on the distortion of rubber to realize.Mostly its locking form is eyelet bolt and pressing plate fit form.In operation of ship, under the atrocious weather condition, because the impulse force of wave; The pressure that acts on the hatchcover cover plate is very big, and the caulking gum on the hatchcover cover plate is too compressed, and between eyelet bolt and pressing plate, produces the gap; Eyelet bolt is deviate from pressing plate, and locking was lost efficacy.For avoiding this situation to take place, it is very important that the restriction hatchcover moves down.And for little hatchcover and oil tank hatchcover in bow 1/4 zone, the related specifications of International Association of Classification Societies (IACS) (IACS) explicitly calls for the little hatchcover in this zone with the relevant latching device of oil tank hatchcover the supporting pad that prevents that hatchcover from moving down will be arranged.Currently mostly be that in the supporting pad form of using on little hatchcover and the oil tank hatchcover supporting pad is welded on the flap of latching device.
The utility model content
The purpose of the utility model; Provide a kind of spacing adjustable cover plate pinch device; The utility model replaces the welding supporting pad with adjustable bolt; The amount of compression of rubber can be adjusted, when ageing of rubber or cover plate modification, still can reach good close performance, and can prevent that adjustable bolt is loosening because of the vibrations reason downwards.
The technical scheme that adopts for achieving the above object is:
A kind of spacing adjustable cover plate pinch device comprises pressing plate, hinge seat, eyelet bolt and bearing pin;
Pressing plate is the stripe board that has elongated slot, and the left end of pressing plate is welded on the cover plate of ship hatchcover;
The left end of hinge seat is welded on the coaming plate of ship hatchcover, and vertical screw and transverse holes are arranged respectively on the front carrier plate of hinge seat and the rear carrier plate;
The bearing pin front end has pin shaft hole;
There is axis hole the eyelet bolt lower end, and eyelet bolt top is installed with fly nut;
Insert between the front carrier plate and rear carrier plate of hinge seat the eyelet bolt lower end, and bearing pin passes transverse holes, the axis hole on the eyelet bolt, the transverse holes on the rear carrier plate and the back-up ring on the front carrier plate successively, and a spring cotter passes the pin shaft hole of bearing pin front end; Eyelet bolt can rotate around bearing pin;
Two adjustable bolts screw in respectively in the front carrier plate and the vertical screw on the rear carrier plate of hinge seat, and the nut of two adjustable bolts is a hexagon, and the upper end of two hexagonal (hexagon)nuts is replaced respectively on the cover plate edge.
Above-mentioned hexagonal (hexagon)nut one side has high platform.
The upper end of eyelet bolt is equiped with packing ring.
During locking, eyelet bolt is spun on the cover plate, tightens the fly nut on the eyelet bolt, and the rubber pad on the cover plate is pressed on the coaming plate.Adjustable bolt can be regulated the gap between cover plate and the hinge seat, gap smaller during screw-in, and the gap becomes big during back-out.
The utlity model has following advantage and beneficial effect:
The utility model has replaced the welding supporting pad with adjustable bolt, makes the amount of compression of rubber to adjust.When ageing of rubber or cover plate distortion, rubber compress variation originally can't satisfy the leak free requirement, and bigger compressive deformation need be arranged between rubber pad and coaming plate.In this case, can screw in adjustable bolt, make the gap between cover plate and the adjustable bolt become big, cover plate can move down bigger distance, has promptly strengthened the compressive deformation of rubber, reaches the leak free requirement again.The little high platform retaining of adjustable bolt upper end when cover plate is closed, can't rotate adjustable bolt at the edge of cover plate, promptly plays spacing effect.Prevent that adjustable bolt is owing to reasons such as vibrations are loosening downwards.This device, simple in structure, easy to use, dependable performance.
Description of drawings
Fig. 1 is a kind of example structure scheme drawing of the utility model.
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
A kind of spacing adjustable cover plate pinch device comprises pressing plate 2, hinge seat 1, eyelet bolt 4 and bearing pin 6, it is characterized in that:
Bearing pin 6 front ends have pin shaft hole 7; There is axis hole 17 eyelet bolt 4 lower ends, and eyelet bolt 4 tops are installed with fly nut 3;
Insert between the front carrier plate 12 and rear carrier plate 13 of hinge seat 1 eyelet bolt 4 lower ends; Bearing pin 6 passes transverse holes 15 and the axis hole 17 and the back-up ring 9 of eyelet bolt lower end on front carrier plate 12, the rear carrier plate 13 respectively; Insert spring cotter 5 in the pin shaft hole 21 of bearing pin 6 front ends; Eyelet bolt 4 tops are installed with fly nut 3, and eyelet bolt 4 can be around bearing pin 6 rotations;
Two adjustable bolts 8 screw in respectively in the front carrier plate 12 and the cooresponding vertical screw 14 on the rear carrier plate 13 of hinge seat 1, and the nut 18 of two adjustable bolts 8 is a hexagon;
Upper end one side of two hexagonal (hexagon)nuts 18 has high platform 19;
The upper end of eyelet bolt 4 is equiped with packing ring 7.
During locking, eyelet bolt 4 is spun on the cover plate, tightens the fly nut 3 on the eyelet bolt 4, on the coaming plate 16 that the rubber pad on the cover plate 20 is compressed.When needs adjustment rubber amount of compression, screw in or back-out adjustable bolt 8, can change the distance that cover plate moves downward or upward, realize the change of amount of compression.Rubber compression quantitative change is big during screw-in, and the rubber amount of compression diminishes during back-out.
