A. B. C. D) after passing through the fixed pulley; and a hydraulic power unit is connected with the anti-rolling oil cylinder (2. A. B. C. D) by an oil channel pipe. The invention has the advantages that the system has simple structure, lower manufacture cost, easy realization, good anti-rolling effect and the like; the hoisting swing angle is attenuated according to an exponential form; when the structural parameters of the system are determined, the hydrocylinder-type anti-rolling system has a structural parameter matching hoisting weight with the best anti-rolling effect (the shortest attenuation time).
Description
Technical field:
The present invention relates to a kind of hydrocylinder-type anti-rolling system that is used for hoisting crane, characteristics such as particularly simple in structure, that manufacturing cost is lower, be easy to realize and stabilizing efficiency is good are to use more sway stabilisation system in the present container handling crane.
Background technology:
No matter being that the active of lift heavy is anti-shakes or passive the subtracting of lift heavy shakes, and it is anti-to shake, subtract the pattern of shaking control system (device) generally that mechanical type, hydraulic oil cylinder type, steel rope are cable-styled, mechanical electronic mode and smart electronics formula.Anti-the shaking of mechanical type can reduce two kinds of forms: the one, and the energy by mechanical means consumption swing is to reach the purpose that final elimination lift heavy waves, and most of mechanical type anti roll devices all are based on this principle; The 2nd, suppress to wave by increasing the suspension rigidity.The general mechanism of mechanical type anti roll device complexity, poor reliability, the maintenance amount is big, and the anti-effect of shaking is unsatisfactory when hoist rope is longer, though obvious in the anti-effect of shaking of at full load, when zero load, amplitude of oscillation decay is slower, slow in reacting.
Summary of the invention
The technical problem to be solved in the present invention, provide a kind of hydrocylinder-type anti-rolling system that is used for hoisting crane, characteristics such as particularly simple in structure, that manufacturing cost is lower, be easy to realize and stabilizing efficiency is good are to use more sway stabilisation system in the present container handling crane.
Major technique characteristics of the present invention are: mainly comprise suspender, hoisting drum, trolley frame, hoisting drum passes fixed pulley by hoist rope and is connected with suspender, be arranged on subtracting on the trolley frame by the chain gearing connection and shake reel, described subtracting shakes reel and is connected by the fixed pulley group that subtracts on shaking steel rope (5.a.b.c.d) and being arranged on trolley frame, subtract and shake steel rope (5.a.b.c.d) and pass the fixed pulley group again and be arranged on fixed pulley group cross connection on the suspender, subtract and shake steel rope (5.a.b.c.d) and pass movable pulley at last and connect and to subtract the piston rod that shakes oil cylinder (2.A.B.C.D), hydraulic power unit shakes oil cylinder (2.A.B.C.D) and is connected with subtracting by the oil circuit pipe.
Major technique characteristics of the present invention also are: electrical motor connects a plunger pump, and plunger pump passes a reducing valve, check valve group and subtracts and shakes oil cylinder (2.A.B.C.D) and be connected by the oil circuit pipe, and the constant pressure valve connects solenoid directional control valve by the oil circuit pipe.
Beneficial effect of the present invention is: system has characteristics such as simple in structure, that manufacturing cost is lower, be easy to realize and stabilizing efficiency is good, the lift heavy pivot angle is by the exponential form decay, when system structure parameter was determined, the hydraulic pressure sway stabilisation system existed the construction parameter of a stabilizing efficiency best (fall time is the shortest) to mate mass per liter.When not mated mass per liter above this, damping of oscillations can not take place in the lift heavy pivot angle, and it is more little to play mass per liter, owing to be subjected to the influence of hydraulic efficiency pressure system damping, fall time is long more.When having mated mass per liter above this, damping of oscillations can take place in the lift heavy pivot angle, prolong with the increase that plays mass per liter fall time, the decay of lift heavy pivot angle is subjected to the long influence of raising line less, improve stabilizing efficiency and not obvious by changing raising line length, when the long timing of raising line, there is an optimum structure parameter load ratio in the hydraulic pressure sway stabilisation system, its scope is about 1.5 ~ 2.05, in this scope,, can obtain good stabilizing efficiency according to the size of the variation adaptively changing construction parameter that plays mass per liter.Especially having worked as mass per liter is zero, when promptly suspender is unloaded, makes sway stabilisation system have the rational structure parameter, can reach the purpose of quick contraposition better.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the hydrocylinder-type anti-rolling system constructional drawing
Fig. 2 is the hydrocylinder-type anti-rolling system schematic diagram
The specific embodiment
As shown in Figure 1, system is by shaking reel 8 with subtracting of lifting mechanism synchronization lifting, subtracting and shake steel rope 5, subtract and shake oil cylinder 2 (comprising A, B, C, D), hydraulic power unit 11 and assembly pulley 4 etc. and form.Subtract and shake steel rope 5 (comprise rope a, b, c, d) and link to each other with intersecting with the fixed pulley group 4 of suspender 1, subtract and shake reel 8 and follow hoisting drum 9 by chain gearing 10 and rotate synchronously by the fixed pulley group 4 on the trolley frame 7.Because starting or braking when making suspender 1 produce swing,, make the roller fading of lift heavy when cart or trolley frame 7 owing to subtract the cross-connection system of shaking rope and the effect of hydraulic efficiency pressure system.When the initial swing of lift heavy to the right the time, rope a and rope b pulling force increase (in tension), rope c and rope relative the reducing of d pulling force (being in relaxed state), the piston rod of A, B hydraulic ram stretches out to the rod chamber side under rope a and rope b tension, and the oil cylinder cavity pressure raises; When pressure reaches the settling pressure of by pass valve, by pass valve is opened, pressure oil is through the by pass valve oil sump tank: meanwhile, with slack-side steel rope bonded assembly hydraulic actuating cylinder C and D under the effect of hydraulic efficiency pressure system oil pressure, piston rod makes lax relatively rope c and rope d be in the tensioning state of certain journey again to rodless cavity side retraction; When lift heavy was swung left, the sense of motion of the piston rod of the state of a that restricts, rope b and rope c, rope d and A, B, C, D oil cylinder was opposite when then putting with lift heavy is right.Through swinging of said process, constantly there is pressure oil to flow out from by pass valve, under the hydraulic oil shock damping action, the Conversion of energy that lift heavy is swung is the energy of hydraulic oil buffering, reaches lift heavy and subtracts the purpose of shaking with the quick contraposition of hoisting crane.
This system is by the hydraulic circuit control lifting mechanism lifting of 2 different pressures as shown in Figure 2, low tension loop guarantees to subtract that to shake steel rope synchronization lifting resistance little, but during tensioning cart and wheeling mechanism work at any time, high tension loop is guaranteed to subtract and is shaken steel rope bigger tensile force is arranged, to produce good stabilizing efficiency.
