Description
Technical field
The present invention relates to rotatable multilayer energy-absorbing quay fenders, belong to ship domain.
Background technology
Quay fenders are a kind of elastic buffering mechanisms on the harbour, are mainly pulled in shore or mooring to slow down ship
To the impact force of harbour in journey, ship is prevented or eliminated, harbour is damaged, fender common at present includes cylinder type fender, D types
Fender, super arch fender and drum type rubber fender etc..These fenders generally carry out energy-absorbing by rubber elastomeric material, inhale
Energy ability is limited, and counter-force is relatively large, and the frictional force between fender and hull is larger, has damage to hull itself, and reduce
The service life of fender.
Invention content
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention to provide a kind of rotatable multilayer energy-absorbing
Quay fenders reach best energy-absorbing effect by multilayer buffer structure, at the same reduce in such a way that fender rotates about the axis hull with
The horizontal friction force in fender body surface face.
Technical solution：To achieve the above object, rotatable multilayer energy-absorbing quay fenders of the invention, including fender body,
The fender body is connect with impingement baffle, and impingement baffle is connect with a pair of of spring, and spring is fixedly connected with rotating arm respectively, two rotations
Arm is separately mounted to the both ends of pivot, be connected below pivot there are two upper connecting pole, upper connecting pole passes through rubber spring and lower company

The spring other end is welded on the second rebound, and the second rebound is connect by bolt with rotating arm.
Preferably, the both ends of the pivot are extended with cylinder boss, rotating arm is sleeved on cylinder boss, cylinder boss
End is equipped with fixed plate by bolt, limits the movement of rotating arm.
Preferably, the fender body is connect by a pair of of stretch cord with harbour.
Preferably, the fender body is equipped with crash sensor module, controller, collision sensing are installed on harbour
Device module and controller carry out wireless data transmission, air bag component module are equipped in the both sides of pedestal, in air bag component module
Switch is installed, switch is connect with controller signals, when crash sensor module detects that impact force is greater than the set value, controller
Control switch opens air bag component module, the inflation of air bag component module.
Preferably, the air bag component module includes upper gas cell, partition board and lower gas cell, filled under in upper gas cell
Air bag is stored with different chemical substances respectively, and partition board is equipped with opening, cover board and bottom plate is equipped in opening, below cover board
Upper limit plate is installed, lower limiting board is installed on bottom plate, cover board, upper limit plate, lower limiting board and bottom plate are equipped with up and down
The straight slot of perforation, is equipped with movable plate between upper limit plate and lower limiting board, and movable plate separates straight slot so that upper gas cell
It cannot be contacted with the chemical substance of lower gas cell, movable plate is connected with the pulling plate of irony, the sky formed between cover board and bottom plate
Electromagnet is installed, electromagnet is connected with switch, and switch is connect with controller, and when the switches are opened, electromagnet does not have magnetic in chamber
Power, movable plate separate straight slot, and when the switch is closed, pulling plate is sucked by magnetic force for electromagnet energizing magnetic, thus will
Movable plate pulls open, straight slot conducting, gas cell inflation.
Preferably, being equipped with limited block on the cover board and bottom plate, the shearing force that limited block fractures is produced less than electromagnet
Raw magnetic force.
In the present invention, using the microcellular elastomeric volume property of polyurethane, as the main of the fender body being in direct contact with ship
Material.This material has a high potential compared to energy-absorbing for traditional rubber material, when polyurethane guard rail deformation reaches 70%
Certain energy-absorbing buffering can still be played the role of.Therefore in the case of the improper berthing of hull or a small amount of overload, polyurethane
Material fender body has more superiority.In addition, fender body is using the convex circular profile design of middle concave surrounding, intermediate groove can be with
The contact area for increasing hull and fender reduces pressure, increases the ability of energy-absorbing buffering.Outside is convex arc structure, is contributed to
The diffusion of loading force substantially increases and resists vertical load ability.The round impingement baffle of polyurethane guard rail body rear connection simultaneously, into
One step increases impact resistance.
In the present invention, two pieces of spring layers are installed in impingement baffle rear successively along its vertically symmetrical axis, largely play
The effect of energy-absorbing buffering.
In the present invention, fender body is connect by rotation system with harbour, after hull is contacted close to harbour and fender body
Since itself has horizontal velocity, certain horizontal friction force can be generated to fender surface, fender body is made by this rotation system
Certain angle can be pivoted along hull directional velocity, hull is made to remain central collision state with fender surface, to
Reduce the horizontal friction force of hull and fender surface, reduces the friction damage to hull.This design compensates for existing fender pair
Reduce the defect in terms of horizontal friction, current this field designer is ignored.In addition, the rubber in the rotation system
Certain cushioning effect is carried while spring makes it be not take up redundant space, realizes multilayer energy-absorbing.Pass through between pedestal and harbour
Connecting screw is equipped with rubber pad, reduces ship side protector due to being collided the pressure at right angle generated to harbour by hull.
In the present invention, fender body is connected directly with two stretch cords with harbour, and stretch cord is located at the left and right of whole device
Fender body is retracted the original state parallel with harbour wall by both sides after hull leaves fender by the elastic force of stretch cord itself.
Advantageous effect：The rotatable multilayer energy-absorbing quay fenders of the present invention, pass through polyurethane guard rail body, impingement baffle, bullet
Spring layer and connect intercolumniation rubber spring in the case that be not take up redundant space reached multilayer energy-absorbing, reduce counter-force mesh
, greatly improve energy absorption ability and anti-impact force；Fender is connected by this structure type by rotation system with harbour, in hull
When berthing fender surface has certain level speed, fender body can be certain along the rotation of vertical pivots direction along hull directional velocity
Angle reduces horizontal load, and the friction damage to hull to reduce the frictional force between hull.
