Abstract
The utility model discloses a telescopic limit boarding ladder which comprises a ship limit chute, a ship sliding base, a ship telescopic cylinder, a boarding ladder, a wharf limit chute, a wharf sliding base and a wharf telescopic cylinder, wherein the ship limit chute is fixed on a ship, rolling wheels are arranged at the bottom of the ship sliding base and move forwards and backwards in the ship limit chute; the ship telescopic cylinder is arranged in the ship sliding base, and comprises a first piston rod connected with one end of the boarding ladder; the wharf limit chute is fixed on a wharf, and rolling wheels are arranged at the bottom of the wharf sliding base; and the wharf telescopic cylinder is arranged in the wharf sliding base and comprises a second piston rod connected with the other end of the boarding ladder. The telescopic limit boarding ladder can change enormous pulling force caused by ship shaking into forward and backward force through the cylinders and springs, forward and backward movement of the sliding bases in the limit chutes is utilized for timely buffering, so that the stability of the boarding ladder is kept, and moreover, the telescopic limit boarding ladder has a lighting function.
Description
Technical field
The utility model relates to a kind of boats and ships accessory, relates in particular to a kind of telescopic spacing boarding ladder.
Background technology
After boats and ships pull in to shore, on passenger, go ashore, loading or unloading goods all will rely on boarding ladder, after spitkit pulls in to shore, people often use a plank frame between boats and ships and harbour, form easy boarding ladder, realize on-board and off-board, but hull fitfull under the promotion of wind-force and wave rocks, the danger that so easy boarding ladder is easy to fall.
On large-scale boats and ships, be equipped with specially boarding ladder, boarding ladder is made by metal material, be erected between boats and ships and harbour, although very firm, boats and ships when rocking to boarding ladder to pull application force larger, boarding ladder need to bear the strength of whole boats and ships, just can damage very soon, and replacement cost is large.
Summary of the invention
The purpose of this utility model: a kind of telescopic spacing boarding ladder is provided, can keeps stable being connected between boats and ships and harbour of boarding ladder, safety when effective guarantee on-board and off-board and handling goods.
To achieve these goals, the technical solution of the utility model is:
A telescopic spacing boarding ladder, comprises boats and ships limit sliding chutes, boats and ships sliding bottom, boats and ships telescopic cylinder, boarding ladder, harbour limit sliding chutes, harbour sliding bottom and harbour telescopic cylinder; Described boats and ships limit sliding chutes is fixed on boats and ships, and the bottom of described boats and ships sliding bottom is provided with pulley, and described boats and ships sliding bottom moves forward and backward in boats and ships limit sliding chutes by described pulley; Described boats and ships telescopic cylinder is arranged in boats and ships sliding bottom, and described boats and ships telescopic cylinder includes the first piston bar that connects boarding ladder one end; Described harbour limit sliding chutes is fixed on harbour, and the bottom of described harbour sliding bottom is provided with pulley, and described harbour sliding bottom moves forward and backward in harbour limit sliding chutes by described pulley; Described harbour telescopic cylinder is arranged in harbour sliding bottom, and described harbour telescopic cylinder includes the second piston rod that connects the boarding ladder other end, and described boarding ladder is connected with harbour with boats and ships respectively with the second piston rod by first piston bar.
Above-mentioned telescopic spacing boarding ladder, wherein, on described first piston bar and the second piston rod, cover has spring respectively.
Above-mentioned telescopic spacing boarding ladder, wherein, the safety while going on board in order to improve, described boarding ladder is provided with illuminating lamp.
The huge power of pullling that the utility model can rock boats and ships is dissolved the power for front and back by cylinder and spring, utilizes seesaw the in time buffering of sliding bottom in limit sliding chutes, keeps the stable of boarding ladder, also has illumination functions.
Accompanying drawing explanation
Fig. 1 is the front view of a kind of telescopic spacing boarding ladder described in the utility model.
Accompanying drawing acceptance of the bid note is described below: 1, boats and ships limit sliding chutes, 2, boats and ships sliding bottom, 3, boats and ships telescopic cylinder, 4, boarding ladder, 5, harbour limit sliding chutes, 6, harbour sliding bottom, 7, harbour telescopic cylinder, 8, pulley, 9, spring, 10, illuminating lamp.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate embodiment of the present utility model.
Refer to shown in accompanying drawing 1, a kind of telescopic spacing boarding ladder, comprises boats and ships limit sliding chutes 1, boats and ships sliding bottom 2, boats and ships telescopic cylinder 3, boarding ladder 4, harbour limit sliding chutes 5, harbour sliding bottom 6 and harbour telescopic cylinder 7; Described boats and ships limit sliding chutes 1 is fixed on boats and ships, and the bottom of described boats and ships sliding bottom 2 is provided with pulley 8, and described boats and ships sliding bottom 2 moves forward and backward in boats and ships limit sliding chutes 1 by described pulley 8; Described boats and ships telescopic cylinder 3 is arranged in boats and ships sliding bottom 2, and described boats and ships telescopic cylinder 3 includes the first piston bar that connects boarding ladder 4 one end; Described harbour limit sliding chutes 5 is fixed on harbour, and the bottom of described harbour sliding bottom 6 is provided with pulley 8, and described harbour sliding bottom 6 moves forward and backward in harbour limit sliding chutes 5 by described pulley 8; Described harbour telescopic cylinder 7 is arranged in harbour sliding bottom 6, and described harbour telescopic cylinder 7 includes the second piston rod that connects boarding ladder 4 other ends, and described boarding ladder 4 is connected with harbour with boats and ships respectively with the second piston rod by first piston bar.
On described first piston bar and the second piston rod, cover has spring 9 respectively, and available buffer boats and ships rock the tensile force of generation.
Boats and ships to dissolving as propelling thrust forward and backward by boats and ships telescopic cylinder 3, and utilize spring 9 and boats and ships telescopic cylinder 3 bufferings when irregular rocking, and boats and ships sliding bottom 2 is slided in the interior front and back of boats and ships limit sliding chutes 1; On the other hand, the power that boats and ships rock is delivered on the second piston rod of harbour telescopic cylinder 7 by boarding ladder 4, by spring 9 and harbour telescopic cylinder 7 bufferings, harbour sliding bottom 6 is slided in the interior front and back of harbour limit sliding chutes 5, greatly improved the stability of boarding ladder 4.
Safety while going on board in order to improve, described boarding ladder 4 is provided with illuminating lamp 10, can see the step of underfooting clearly.
In sum, the huge power of pullling that the utility model can rock boats and ships is dissolved the power for front and back by cylinder and spring, utilizes seesaw the in time buffering of sliding bottom in limit sliding chutes, keeps the stable of boarding ladder, also has illumination functions.
