A kind of ship's crane with anti-swing mechanism
Technical field
This utility model relates to a kind of crane, a kind of ship's crane with anti-swing mechanism.
Background technology
Ship's crane, is a kind of big deck machinery on ship, and it is the equipment of a kind of ship loading and unloading goods.
Ship's crane container of the prior art is anti-shakes that mode moment motor for preventing shakes, hydraulic pressure anti-shakes, eight
Rope is anti-to be shaken and electronic anti-swinging mode etc..It is compared to each other and draws: torque motor is anti-shakes mode simple in construction, but
Torque motor slip ring and brake are easily lost, and maintenance and repair is frequent;Hydraulic pressure anti-sway system compact conformation, but
Need to increase the hydraulic means such as hydraulic power unit, high to later maintenance cost of upkeep;Eight rope anti-sway systems are anti-shakes effect
Fruit substantially, but adds the complexity of vehicle structure, and dolly weight increase is relatively big, and steel wire rope detours positive and negative
In service life is greatly reduced, add maintenance and use cost;Electronic anti-swinging system can effectively suppress to wave,
But its detecting element and sensor unit are the highest, and the most frequently the adjustment speed of service makes operation
Personnel are uncomfortable, increase labor intensity of operating staff.

Generally under state, when hydraulic system does not works, (include the situation that hydraulic system breaks down), sub, female
Friction plate mutually compresses under butterfly spring 415 pressure effect, i.e. clutch apparatus 403 is in normally off,
Friction plate phase mutual friction the most sub, female, two grades of axle first gears 404 are rubbed by son, mother with two grades of axles 414
The frictional force of pad links together, two grades of axle first gears 404 drive two grades of axles 414, then drive two grades
Axle the second gear 416 rotates, and two grades of axle second gears 416 drive the three grades of axle teeth arranged on three grades of axles 401
Wheel 412, makes three grades of axles 401 rotate, so that the limit speed for braking condition device 413 arranged on three grades of axles 401 brakes;
When clutch apparatus 403 is to be opened, hydraulic system is started working, and clutch plunger set 402 is at hydraulic pressure
Move right under oil effect, between friction plate, female, there is no pressure, friction plate decilitre, female, i.e.
Two grades of axles 414 disengage with two grades of axle first gears 404 and couple.Now limit speed for braking condition device 413 does not works,
Hydraulic motor 406 band movable reel 418 rotates, and steel wire rope 10 is wound around on reel 418 and tightens up, steel wire rope 10
Slided by first pulley assembly the 1, second pulley assembly the 2, the 3rd pulley assembly 3, make suspension hook with goods one
Rise and rise;Steel wire rope 10 is decontroled on reel 418, and steel wire rope 10 is sliding by the first pulley assembly 1, second
Wheel assembly the 2, the 3rd pulley assembly 3 slides, and makes suspension hook decline with goods;The normal receipts of steel wire rope 10
Knock off work, it is achieved suspension hook effectively rises at differing heights, declines;
When clutch apparatus 403 is to be closed, under the effect of butterfly spring 415, clutch plunger set 402
In hydraulic oil be discharged, clutch plunger set 402 compresses son, female friction plate again simultaneously, makes braking limit
Speed variator 413 brakes, and makes reel 418 stop operating, and steel wire rope 10 stops being wound around on reel 418,
Suspension hook stops rising, declining;
When hydraulic system can not work, use manual mode.When i.e. hydraulic system breaks down, clutch
Device 403 closes automatically, and limit speed for braking condition device 413 is started working, and the most first installs hand gear 419,
Make three grades of axles 401 be linked together with hand gear 419, rotate forward on hand gear 419 arrange shake
, making steel wire rope 10 be wound around on reel 418 and tighten up, suspension hook rises, and completes manual work;
This anti-swing mechanism has enough anti-oblique pullings that shakes in design, and prevents shaking moment by closed-loop vector control
Variable frequency drive motors output, can with playing a liter weight, height and the suspender amplitude of oscillation adjust in real time, improve operation
Efficiency;
Through on-the-spot actually detected, under unloaded and heavily loaded operating mode, suspender swings in the cycle, prevents shaking machine
Container 21 full swing amplitude all can be controlled in ± 100mm by structure, and tends to static, meets design pre-
Phase target.
It follows that this utility model provides a kind of ship's crane with anti-swing mechanism, anti-swing mechanism is adopted
Subtract that to shake cable drum be four, subtract that to shake steel wire rope be four, four subtract and shake steel wire rope and arrange in space
On be equal length, subtract and shake steel wire rope one end and be separately fixed on four hangers, the other end is respectively by guiding
Pulley is wrapped in subtract and shakes on cable drum, plays and prevents shaking effect, it is ensured that container spreader stable state safety work
Improve work efficiency, reduce labor intensity of operating staff, there is compact conformation, installation, easy to use,
Low cost, the advantage that work efficiency is high.
