Description
Technical field
The invention belongs to technical field of ships, and in particular to a kind of ship dragline structure.
Background technology：
Existing ship to bank stop when, it is necessary to the traction of rope.Traditional way is that rope is directly thrown bank, by
Rope set is set on the timber on bank by people on the bank, ship is not departed from bank under wave action.But this tradition
Way have the following disadvantages：1st, ship is usually that stern or fore first pull in shore when stopping, and the end of rope is located at ship
The center of oceangoing ship, under wave action, ship fluctuates, during floating, due to rope and ship front end or
Person does not fix rear end, so the direction that ship is stopped can change, causes fore or stern to depart from bank, causes next time
It is relatively difficult when going on board；2nd, for ship during floating, rope produces huge friction with ship side, causes rope to be damaged, and restricts
Suo Yidan is broken, and ship can not just pull in shore, this just needs manually periodically to check rope, wasting manpower and material resources.
For this reason, people have invented a kind of cable traction structure, this hitch structure is fixed on the bow or stern, and rope is risen
Guiding role, after ship is stopped, fore or stern are without departing from bank.
The Chinese patent of Application No. 201420628832.3 discloses a kind of dragline structure of ship, belongs to mechanical technique
Field.It solves the problems, such as that frictional force is big between existing dragline structure and rope, structure is unstable.The dragline knot of this ship
Structure, is arranged on the ship side of ship, including the dragline body with dragline portion and connecting portion, and connecting portion is cylindrical, and dragline portion is in
Circular and its inside has mooring hawse, has the connecting hole being vertically arranged on ship side, and connecting portion is threaded through in the connecting hole, even
Connecing the top in hole has ring-shaped step one, its inner ring and the bearing one of connecting portion tight fit, bearing one are equipped with ring-shaped step one
Outer ring be resisted against on the ring-shaped step one, the lower end of connecting portion is arranged with screwed retaining ring.
But the technical solution of above-mentioned patent is relatively complicated in installation, dismounting and replacement, due to bearing one and bearing
Two are mounted in connecting hole, when mounted, it is necessary to by equipment of the dragline body outside by connecting portion " pounding " into bearing one
With being allowed to be interference fitted with bearing one and bearing two in bearing two, assembly and disassembly are all more troublesome.
Therefore, for the ease of the Fast Installation of dragline body, dismounting and replacement, the present invention to ship side upper end volume mounting groove with
And the structure of dragline body is improved, to solve the defects of above-mentioned existing.
The content of the invention
It is an object of the invention to provide a kind of ship dragline structure, Fast Installation, dismounting for the ease of dragline body with
And replace.
A kind of ship dragline structure, is arranged on the ship side of ship, including the dragline body with dragline portion and connecting portion, even
Socket part is cylindrical, and dragline portion has mooring hawse in circular and its inside, and the ship side is equipped with the mounting groove being vertically arranged,
The bottom of the mounting groove is equipped with spacing straight slot, and spacing straight slot is distributed with mounting groove coaxial line, and the end face of the ship side is upper
Annular groove is equipped with the periphery of mounting groove, rolling bearing is cased with above-mentioned connecting portion, the periphery of above-mentioned connecting portion is equipped with set
Cylinder, the inner ring of the rolling bearing and the outer wall of connecting portion are interference fitted, and the outer ring of rolling bearing and the inner wall interference of sleeve are matched somebody with somebody
Close, the outer wall of the sleeve, which is equipped with, to be equipped with annular flange and use with the matched annular flange of annular groove, annular groove
In the location hole of installation positioning bolt, the end of the connecting portion is arranged with screwed retaining ring.
Preferably, the diameter of the spacing straight slot is less than the diameter of mounting groove, and the diameter of the spacing straight slot is more than connection
The diameter in portion, the outer wall of sleeve and the bottom of the inner wall clearance fit of mounting groove and sleeve closely contact the upper end of spacing straight slot
Face.
Preferably, the upper surface of the spacing straight slot is equipped with card slot, and the lower face of the sleeve is equipped with to be engaged with card slot
Fixture block, sleeve be installed on mounting groove after fixture block be connected in card slot.
Preferably, the lower end of the connecting portion is equipped with external screw thread, and the screwed retaining ring is threadedly coupled with connecting portion.
The advantage of the invention is that：Can quickly by dragline body installation on the quarter on mounting groove in, shorten installation,
Dismounting and the time replaced, operating efficiency is improved, reduces operating process.
