Thus, the present inventor considers to improve existing boarding ladder structure, and this case produces thus.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of movable boarding ladder being engaged in 600t maritime patrol ship and using, and it utilizes movable roller vehicle to coordinate with multistage registration device to realize can according to the change of tide from land to the movable boarding ladder ship.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of movable boarding ladder, this boarding ladder comprise movable harbour connecting device, ship's ladder and with deck connecting device; Described harbour connecting device and deck connecting device lay respectively at the two ends of ship's ladder, harbour connecting device comprises portable roller vehicle and body cradle, described ship's ladder one end to be articulated with on body cradle and can be that axle rotates with hinge-point, described roller vehicle is provided with multistage registration device and ship's ladder and is connected to form the location structure that Multi-stage rotary regulates.
Further, described multistage registration device comprises fixed link and articulated bracket, and described fixed link one end is fixed on roller vehicle, this fixed link other end be positioned at articulated bracket corresponding end groove and with this articulated bracket coordination hinge, described articulated bracket is fixedly connected with ship's ladder.
Further, on the groove inner wall of described articulated bracket and the other end termination of fixed link all has teeth and fit engagement, thus forms multistage location structure.
Further, described teeth are arranged upward.
Further, between described fixed link and articulated bracket, be provided with spring, form reset and protection structure.
Further, described body cradle is be fixed on the supporting structure on running roller car, and described roller vehicle comprises the roller of gimbaled platform and below thereof, thus forms movable structure, guarantees the nimble property that boarding ladder uses.
Further, described deck connecting device is three corner steady, and its attachment screw or bolt-locking are in advance on ship deck.
Further, deck micro-adjusting mechanism is provided with between described deck connecting device and ship's ladder.
Further, described deck micro-adjusting mechanism comprises the Ring gear that is fixedly connected with ship's ladder and is connected gear wheel shaft with deck connecting device, described Ring gear is tubular and inwall is provided with teeth, and described gear wheel shaft outside face is provided with teeth, Ring gear and gear wheel shaft are socketed and engage each other thus form fine tuning structure.
Compared with prior art, advantage of the present utility model:
The movable boarding ladder of the utility model effectively reduces the difficulty of going on board caused because of tidal fluctuations, and this ladder has the movable scope of multiple directions, can not be subject to boats and ships when harbour, the front and back caused by tide, far and near moving influence; In addition, this terraced dismounting, convenient transportation, lightweight, floor area is little, safety factor is high, cost is low, and facilitate the construction in harbour stage.
