Description
Technical field
It the utility model is related to ships and light boats technical field, and in particular to a kind of screw lifts gangway ladder.
Background technology
Current middle-size and small-size ships and light boats do not prepare special gangway ladder when dispatching from the factory, thus most units use springboard, or system
Make " gangway ladder " of the simple steel ladder as shown in Figure 1 as ships and light boats above and below personnel.Although two ways makes crewman's ships and light boats up and down
When " there is road to walk ", but both " gangway ladders " are very heavy, it is necessary to moved by manpower, to be assisted by personnel outside ship during overlap joint
Help personnel on ship to complete, while be difficult to fix, operation difficulty is big.And wind and waves, tidal bulge are met in springboard both sides without guardrail
Ebb, easily produce and wave slip, ships and light boats and personnel are dangerous big up and down, and safety guarantee only relies on the protection network of extra system's dress.
Middle-size and small-size ships and light boats are in berthing fixed quay, and due to tidewater fluctuation, ships and light boats deck can be less than in the time of low water
Harbour, and it is higher than harbour on high water time deck, existing small-sized safety gangway ladder can not use, and equipped on large ship
Gangway ladder needs auxiliary lifting equipment to complete to overlap, though the gangway ladder of going on board that harbour provides largely adapts to the change of tidal range,
After being usually applicable only to landing pier, main deck is higher than the naval vessel of harbour principal plane, is not suitable for minitype ship and uses.
Utility model content
The purpose of this utility model is：A kind of new type of safe gangway ladder is provided to substitute traditional springboard, reduces gangway ladder overlap joint
Difficulty, to the adaptability of hydrological environment when strengthening ships and light boats berthing fixed quay, it is ensured that the personnel of middle-size and small-size ships and light boats and conventional life
The upper and lower gangway ladder of being money is safely, quickly, conveniently.
It is as follows based on the purpose, the technical solution adopted in the utility model：A kind of screw lifts gangway ladder, including is connected to
Two spiral lifting frame bodies on ships and light boats and it is respectively arranged at the intrinsic lifting screw of spiral lifting frame, the lifting screw
Lifting platform is provided with, slider-crank mechanism drives lifting platform to be moved up and down along lifting screw, and the both ends of gangway ladder are connected to liter
Drop on platform.Lifting platform is driven along screw rod upper and lower translation by slider-crank mechanism, so that gangway ladder can move up and down.
Further, the slider-crank mechanism includes the rotary shaft being connected on worm screw, the transmission being connected with rotary shaft
Axle, the handle being connected with power transmission shaft.
Further, the lifting platform is provided with lifting platform projection, and the gangway ladder connection is arranged on lifting platform projection.
Further, the spiral lifting frame body is fixed on ships and light boats by hanger.
Further, the hanger is fastened by bolts device and is fixed on ships and light boats.
Compare prior art, and the utility model has following beneficial effect：（1）Gangway ladder is connected to the lifting platform on screw rod
On, rotating crank slide block mechanism, drive lifting platform to be moved up and down along lifting screw by worm screw, so as to reduce because tidal range becomes
Change and adjust the workload of gangway ladder, improve the security of ships and light boats above and below personnel and goods and materials；（2）In the utility model, spiral liter
Drop frame body to fix on the quarter, for gangway ladder between two spiral lifting frame bodies, two spiral lifting frame bodies distinguish shape
Into the guardrail of both sides, without extra increase guardrail, while ensured staff up and down gangway ladder when security.

Embodiment
The utility model is further described with reference to embodiment and accompanying drawing.
As shown in Fig. 2 a kind of screw lifting gangway ladder, including two Hes of spiral lifting frame body 1 being connected on ships and light boats
The intrinsic lifting screw 2 of spiral lifting frame is respectively arranged at, the lifting screw 2 is provided with lifting platform 3, slider-crank mechanism
4 drive lifting platforms 3 are moved up and down along lifting screw 2, and the both ends of gangway ladder 5 are connected on lifting platform 3.The crank block machine
Structure 4 includes the rotary shaft 41 being connected on worm screw 6, the power transmission shaft 42 being connected with rotary shaft 41, the handle being connected with power transmission shaft 42
43.Swinging handle 43, power is passed to by power transmission shaft 42 by rotary shaft 41, then rotary shaft 41 drives lifting platform 3 by worm screw 6
