Description
Technical field
The utility model belongs to technical field of ships, relates to a kind of dragline structure of boats and ships.
Background technology
When existing boats and ships are stopped to bank, need the traction of rope.Traditional way is that rope is directly thrown bank, is set on the timber on bank by people on the bank by rope cover, makes boats and ships can not depart from bank under wave action.But there is following shortcoming in this traditional way: 1, boats and ships are when stopping, generally that stern or fore first pull in shore, and the end of rope is positioned at the center of boats and ships, under wave action, boats and ships fluctuate, in the process of floating, because rope and boats and ships front end or rear end are not fixed, so the direction that boats and ships are stopped can change, fore or stern is caused to depart from bank, more difficult when causing go on board next time; 2, boats and ships are in the process of floating, and rope and ship side produce huge friction, cause rope impaired, and rope is once fracture, and boats and ships just cannot pull in shore, and this just needs human at periodic intervals to check rope, wasting manpower and material resources.
For this reason, people have invented a kind of cable traction structure, and this hitch structure is fixed on fore or stern, play the guiding role to rope, and after boats and ships are stopped, fore or stern can not depart from bank.But large not and rope and this structure the friction force of the rotation angle range of this structure is large, pulls rope more difficult; This hitch structure is in rotary course, and the existence due to friction force causes the service life of this cable traction structure short.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the dragline structure of a kind of long service life, well-set boats and ships.
The purpose of this utility model realizes by following technical proposal:
The dragline structure of these boats and ships, be arranged on the ship side of boats and ships, comprise the dragline body with dragline portion and connecting portion, described connecting portion is cylindric, described dragline portion is circular and its inside has mooring hawse, it is characterized in that, described ship side has the connecting bore vertically arranged, above-mentioned connecting portion is located in this connecting bore, the top of described connecting bore has ring-shaped step one, its inner ring and the friction tight bearing one of connecting portion is provided with in described ring-shaped step one, the outer ring of described bearing one is resisted against on this ring-shaped step one, the lower end of described connecting portion is arranged with screwed retaining ring.
In the dragline structure of above-mentioned boats and ships, the bottom of described connecting portion has ring-shaped step two, its inner ring and the friction tight bearing two of connecting portion is provided with in described ring-shaped step two, the outer ring of described bearing two is resisted against on this ring-shaped step two, and above-mentioned screwed retaining ring is resisted against on the inner ring of this bearing two.
In the dragline structure of above-mentioned boats and ships, described connecting portion is also arranged with the limiting stopper between bearing one and bearing two, the top of described limiting stopper is resisted against on the inner ring of bearing one, and the bottom of described limiting stopper is resisted against on the inner ring of bearing two.
In the dragline structure of above-mentioned boats and ships, described connecting portion has outside thread, above-mentioned screwed retaining ring and this outside thread in mating connection.
During installation, be first encased in ring-shaped step one by bearing one, penetrated by the connecting portion of dragline body and pass bearing one, now the bottom of connecting bore is stretched in the lower end of connecting portion; Limiting stopper, bearing two and screwed retaining ring are nested into successively on connector, rotary release proof nut, make limiting stopper and bearing two upward movement, limiting stopper is resisted against on the inner ring of bearing one, and the inner ring of bearing two is resisted against on limiting stopper, and locking completes.
When rotating, the outer ring of bearing one, the outer ring of bearing two are in stationary state, and the inner ring of bearing one, the inner ring of bearing two and limiting stopper rotate along with circumference together with connecting portion.
Compared with prior art, the dragline structure of these boats and ships has the following advantages:
Rope is through after this mooring hawse, and friction force between mooring hawse is little, effectively extends the service life of rope; Because dragline body can circumference rotate, the hunting range of rope is large, applied widely; This structural stability is good, and after being locked by screwed retaining ring, connecting portion not easily comes off in connecting bore, after dragline body damages, can unload screwed retaining ring and change dragline body, removes and installs conveniently, effectively extends its service life.
