Description
Technical field
The present invention relates to a kind of jack up boarding ladders, belong to technical field of ships.
Background technology
At present in offshore wind farm work progress the upper lower platform of personnel by cage, and using cage when need by loop wheel machine this
One precious resources influences the efficiency of offshore construction, it is therefore desirable to which research one kind can realize personnel in the case of without using loop wheel machine
The equipment of upper and lower offshore wind farm self-elevating work platform.
Ship etc. above and below personnel when boarding ladder is mainly used for the upper and lower ship of shipyard personnel at present, ship goes to dock.Harbour
It is that harbour is fixed in one end with boarding ladder structure type, the other end is overlapped on ship, since the sea level of dock area is opposite
Calm, ship does not have instantaneous big movement, and the boarding ladder being fixed on harbour only needs can be with the variation of fluctuation tide
It slowly rotates and meets the requirements；Or boarding ladder one end is made to be fixed on ship, the other end is overlapped on harbour, boarding ladder with
Ship is mobile and rotates, and boarding ladder is made to be overlapped on always on harbour, meets personnel's requirement up and down.Although it is fixed on platform
On ladder rung of going on board can be adjusted with the angle change of boarding ladder, but when at sea constructing, put down for offshore construction
The two relative movements of platform and tender are more frequent, and the instantaneous larger ship of relative motion, this harbour with boarding ladder not
Reliably, it is and dangerous.
The content of the invention
It is an object of the present invention to provide a kind of jack up boarding ladders, can be rotated with the movement of tender, and
It can adjust, offshore wind farm self-elevating work platform be influenced small as tender instantaneously moves.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：A kind of jack up boarding ladder, including master
Ladder, tail ladder and pylon, tail ladder are connected with main ladder, and one end of main ladder is fixed on by Assembly of pin on pylon, and the other end passes through cunning
Wheel assembly is connected with the motor being fixed on platform, and spring push-rod, the connector portions of spring push-rod and main ladder are provided on pylon
It connects, is provided with locking device below spring push-rod, locking device is fixed on pylon.
Above-mentioned boarding ladder whole Transporting can be made after processing and manufacturing factory whole processing and debugging to offshore wind farm jack up
On industry platform, integral hoisting.The supporting leg of pylon need to be only welded and fixed during installation, installation difficulty is reduced, sea is greatly saved
The construction and installation time.
Main ladder can be fixed on one end rotation on pylon, convenient for automatic deploying and retracting on pylon, Bu Huizhan by Assembly of pin
With the excessive space of operation platform, the loop wheel machine of platform will not be more occupied, it, will not be because occupying loop wheel machine so as in lower platform on personnel
And influence the construction efficiency on platform.
Tail ladder can instantaneously mobile automatic adjustment reaches Equilibrium with tender.Tail ladder is using self-balancing ladder, using certainly
The cylinder of balancing can reach the balance of any position this principle in itself rotatable scope, for main ladder and tender
Between connection, when tender is instantaneously moved with wave, ocean current, enable instantaneous movement of the self-balancing ladder with tender
And reach any equilbrium position.Step plate on self-balancing ladder remains horizontal by the step plate of linkage mechanism and main ladder,
Facilitate above and below personnel.
The setting of pylon not only avoids the loop wheel machine occupied on platform, and floor space is small, and convenient for fixed main ladder and tail
Ladder reduces main ladder and influence of the tail ladder to operation platform.
A kind of foregoing jack up boarding ladder, the locking device include horizontal collision block, locking pin, spring, it is lower locking case,
Pull rod, steel wire rope, rope cramp and lock handle, horizontal collision block and locking pin connection, locking pin are connected with lower locking case, lower lock
Tight case is connected with pull rod, and one end of the tail end connecting steel wire ropes of pull rod, the steel wire rope other end is connected with lock handle, and spring is set
In locking slightly.Locking device is used to main ladder being fixed on pylon, when main ladder is reset to from use state in pylon, sets
Main ladder is firmly fixed on pylon in the locking device close to pylon top.
A kind of foregoing jack up boarding ladder, the spring push-rod include sliding bar, seamless steel pipe, fixed plate, sliding bar
One end be connected with connector portions, the other end passes through seamless steel pipe exposed end, sets that there are two fixed plates on seamless steel pipe.As general
When main ladder is put down from pylon, using above locking device and being fixed on the spring push-rod on pylon and promote main ladder,
To overcome the problems, such as that due to the center of gravity of main terraced tailing ladder is more than its pivot use state can not be automatically rotated to.Sliding bar by
It gradually extends, and promotes the main ladder being connected with connector portions.
A kind of foregoing jack up boarding ladder, it is described it is main ladder include frame, big pull rod, railing and step plate, big pull rod and
