Abstract

The utility model discloses an adjustable gangplank ladder erected between the wharf and the ship deck, comprising a base, armrests, a movable ladder, a universal wheel, a fixed ladder and pins. The universal wheel and a stop post are arranged under the base, and a rotary plate is arranged on the base. The left end of the horizontal fixed ladder is hinged with the rotary plate through pins; upright posts respectively fixed on both sides of the fixed ladder are fixedly connected with the upper plane of the rotary plate; the middle segments on the lateral sides of the two upright posts are respectively and fixedly connected with winches; pulleys are arranged on the top parts of the winches. The winch arranged on the left upright post is matched with the pulley through a steel rope to draw the fixed ladder to realize the lifting movement. The movable ladder is in parallel with the fixed ladder and is in gap and nesting joint with the fixed ladder; the winch arranged on the right upright post is matched with the pulley through a steel rope to realize traction of the movable ladder, so as to realize the telescopic movement of the movable ladder relative to the fixed ladder. The adjustable gangplank ladder adopts the combination of a hanging bridge structure and a telescopic structure, and can be flexibly erected between the wharf and the ship deck; the adjustable gangplank ladder is particularly applicable to petrochemical wharfs equipped with fireproof and explosion-proof facilities.

Description

Adjustable springboard ladder
Technical field
The utility model relates to a kind of ship's outfit, and specifically, the utility model relates to a kind of springboard ladder.
Background technology
When small-sized oil tanker or cargo ship landing pier, need between boat deck and harbour, set up the springboard ladder that passes through for personnel.The springboard ladder of prior art is an integral structure, and good rigidly, intensity height can satisfy the operating needs that personnel pass through.But structure is that all-in-one-piece springboard ladder length dimension is fixed, and can not stop the best decorating position of distance selection according to ship and harbour, and integrally-built springboard ladder length is longer relatively, moves inconvenience when setting up, also occupy than the large space position during collection, be unfavorable for the harbour management.
The utility model content
The utility model is primarily aimed at the deficiencies in the prior art, propose a kind of simple in structure, length is scalable, height lifting, position-movable adjustable springboard ladder.
The utility model is achieved through the following technical solutions technical goal.
Adjustable springboard ladder, it comprises base, handrail, autostairs, cardan wheel, fixed ladder and pin.Its improvements are: described base end face is provided with cardan wheel and stop stake for four jiaos, the plane is provided with relatively turnable rotating disk on the base, horizontally-arranged fixed ladder left end connects by pin and rotating disk commissure, captive joint two branches in plane are located at the column of fixed ladder both sides on the rotating disk, stage casing, the two root posts outsides respectively the captive joint winch and, the top is provided with pulley, and winch cooperates tractive autostairs left end by cable wire with pulley, and winch cooperates tractive fixed ladder stage casing to be the suspension bridge structure by cable wire with pulley.Described fixed ladder places on the autostairs plane, is the stretching structure of mutual fit between fixed ladder and the autostairs.
Winch in the said structure is a hand winch.The hand winch that is provided with on the column of left side cooperates the tractive fixed ladder to do lifting by cable wire with pulley.Autostairs parallels with fixed ladder and the gap fit, and stretching of autostairs relative fixed ladder cooperates traction to form by the winch that is provided with on the column of right side by cable wire with pulley.The cardan wheel of hand winch when operation and the copper cover of axis hole liner does not produce spark when rolling, and meets the fire-proof and explosion-proof operating needs of petrochemical industry harbour.
The utility model compared with prior art has following good effect:
1, springboard ladder two ends are provided with cardan wheel, are convenient to whole shift position and collection;
2, be provided with the springboard ladder of lifting structure, can in the scantling of structure scope, establish the joint setting height(from bottom) according to the ground-surface diff-H of the relative harbour in boat deck;
3, fixed ladder and autostairs gap fit, the stretching structure of autostairs relative fixed ladder can be regulated in the scantling of structure tolerance band and set up length according to the relative harbour distance of ship side;
4, the cardan wheel of not electricity consumption of hand winch driving and the copper cover of axis hole liner does not in use produce spark, meets the fire-proof and explosion-proof operating needs of petrochemical industry harbour.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is birds-eye vieies of accompanying drawing 1
Accompanying drawing 3 is lateral plans of accompanying drawing 1
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
Adjustable springboard ladder shown in the drawings, it comprises base 1, handrail 2, autostairs 3, cardan wheel 4, fixed ladder 5 and pin 6.Described base 1 is supported on the quay surface by cardan wheel 4 and the stop stake 1.7 that is located at four jiaos of bottom surfaces.The plane is provided with relatively turnable rotating disk 1.1 on the described base 1, horizontally-arranged fixed ladder 5 left ends connect by pin 6 and rotating disk 1.1 commissures, captive joint two branches in plane are located at the column 1.3 of fixed ladder 5 both sides on the rotating disk 1.1, the outside, two root posts, 1.3 stage casings is captive joint winch 1.2 and 1.8 respectively, and the top is provided with pulley 1.4.Winch 1.8 cooperates tractive fixed ladder 5 stage casings by cable wire 1.6 with pulley 1.4, form the suspension bridge type lifting structure.Fixed ladder 5 places on autostairs 3 planes and mutual gap fit, and the flexible of autostairs 3 relative fixed ladders 5 cooperates traction to form by the winch 1.2 that is provided with on the right side column 1.3 by cable wire 1.5 with pulley 1.4.Present embodiment is mounted in the scalable springboard ladder on the petrochemical industry harbour, and winch 1.2 and 1.8 is hand winches in the structure, during use only by manual operation.In addition, the copper covers of axis hole liner in the cardan wheel 4 do not produce spark during rolling and between the steel axle, meet that the petrochemical industry harbour is prevented fires, explosion-proof operating needs.When the utility model is used, can be by the whole shift position of cardan wheel 4 scrolling realization, the installation site screws off stop stake 1.7 after determining, bears main weight by stop stake 1.7.According to the distance of the ground-surface diff-H of the relative harbour in boat deck and ship side and harbour, in the scope of structure permission, regulate setting height(from bottom) and installation length.The cardan wheel 4 of autostairs 5 right-hand members directly is supported on the boat deck, and cardan wheel 4 rolls along with rocking of ship, can avoid the wearing and tearing of springboard ladder to the boat deck.The utility model satisfies the requirement of setting up of ship and harbour relative position by the adjusting of lifting structure and stretching structure in the scantling of structure scope, also be convenient to the collection of springboard ladder simultaneously, saves the harbour space.
