Description
Technical field
The utility model relates to a kind of permanent tension force lifting operation wave compensating device, particularly a kind of compound wave compensating device, for the impact of the heave movement that reduces to cause because of wave on lifting machine and weight.
Background technology
At present the compensation of undulation mode can be divided into two types of Active Compensation and passive compensation, and a kind of is passive compensating device, be energy storage with wave in energy storage, utilize the energy storage accumulation of energy and discharge and realize heave compensation.This method is simple, compensation range extensively, consumption of power energy hardly, larger but its shortcoming is exactly structure, compensation precision is lower slightly; Another kind is the Active Compensation device that drives the work of winch HM Hydraulic Motor by the Hydraulic Pump fuel feeding, the compensation power of this system is mainly derived from charging system, this method can adopt controlled reset, compensation precision is higher, antijamming capability is strong, comformability is good, and compensation performance is stable, but consumed power is large, cost is very high.
The utility model content
The purpose of this utility model provides a kind of simple in structure, compensation precision is high, compensation range is wide permanent tension wave compensation device, to solve the deficiency of above-mentioned technology.
Permanent tension force lifting operation wave compensating device of the present utility model comprises the hydraulic wireline winch 2 of the weight 11 that hoists and drives the HM Hydraulic Motor 3 of winch, the brake equipment 1 that matches with hydraulic wireline winch; Winch links to each other with weight with fixed pulley 17, running block 9 by plunger cylinder 8; Plunger cylinder and piston accumulator group 10 and 13 outlets of oil-supplementing system solenoid directional control valve are joined, and piston accumulator and source of the gas 12 join; HM Hydraulic Motor is joined with the control oil sources, it is characterized in that the pilot piping both sides of HM Hydraulic Motor all are connected with anti-cavitation check valve 5; The lifting side pipeline of HM Hydraulic Motor and balance cock 4 and pressure control plug-in unit 6 join, and pressure control plug-in unit 6 is by proportional pressure control valve 7 controls.
Permanent tension force lifting operation wave compensating device of the present utility model adopts compensation way passive and that Active Compensation combines, has the advantage of two kinds of charging systems concurrently, and is simple in structure, compensation precision is high, compensation range is wide, corresponding speed is fast.
Description of drawings
Fig. 1 is the hydraulic schematic diagram of the permanent tension wave compensation device of the utility model;
Fig. 2 is the structural representation of compensating cylinder in the permanent tension wave compensation device of the utility model;
The specific embodiment
As shown in Figure 1, the utility model comprises the hydraulic wireline winch 2 of the weight 11 that hoists and drives the HM Hydraulic Motor 3 of winch that with the brake equipment 1 that hydraulic wireline winch matches, winch adopts the mesohigh hydraulic-driven.
Winch links to each other with weight with fixed pulley 17, running block 9 by plunger cylinder 8; Plunger cylinder and piston accumulator group 10 and 13 outlets of oil-supplementing system solenoid directional control valve are joined, and piston accumulator and source of the gas 12 join; HM Hydraulic Motor is joined with the control oil sources, and the pilot piping both sides of HM Hydraulic Motor all are connected with anti-cavitation check valve 5; The lifting side pipeline of HM Hydraulic Motor and balance cock 4 and pressure control plug-in unit 6 join.Each hydraulic unit is chosen according to the operating mode needs and is got final product.
In the present embodiment, system adopts six times of passive compensation of multiplying power, be that the oil cylinder assembly pulley comprises four fixed pulleys 17 installing on three movable pulleys 9 of compensating cylinder plunger 15 front installations and the cylinder block 16, the effective compensation stroke of compensating cylinder is six times of compensating cylinder stroke.Pilot bar 14 is installed on the compensating cylinder, is played safe directional tagging.The fluid of balance cock 4 in can locking motor oil circuit keeps certain back pressure.Anti-cavitation check valve 5 is the system oil-way repairing, guarantees air pocket not occur in the hydraulic efficiency pressure system, prevents from letting out in the oil circuit system failure that causes.
Working process is as follows: before winch 2 work, open cylinder braking device 1 by separate button first, again by motor 3 operation winch runnings.When the lifting winch needs compensation of undulation, open source of the gas 12 and be filled with high pressure nitrogen for piston accumulator group 10, then press corresponding button, reversing valve operated 13 is compensating cylinder 8 and Accumulator arrangements 10 repairings, reaches oil compensation pressure and is stopped by system's control repairing work.This moment, charging system can carry out permanent tension compensating, and compensating form is passive compensation.System does not require the expenditure of energy, and compensation range is wide.After compensation work finished, reversing valve operated 13 was compensating cylinder 8 and Accumulator arrangements 10 oil extractions.When meeting with bad working environments or super operating mode operation, when exceeding passive compensation range, can adopt the Active Compensation form to realize permanent tension force.The realization of permanent tension force is by pressure control plug-in unit 6 and proportional pressure control valve 7 controls, and required permanent Tensity size calculates by working condition and weight weight in system, then by the openings of sizes of electric logic control proportional pressure control valve 7, realizes permanent tension force.
When weight 11 rose, the load weight on the rope lightened, and passive compensation is started working, and when exceeding passive compensation range, under the lifting side pressure-acting, winch tightens up steel rope, made rope keep tensioning state; When weight descended, passive compensation began corresponding, proportional pressure control valve 7 overflows when reaching certain pressure, pressure control plug-in unit 6 is opened, part lifting side fluid flows back to fuel tank, keeps like this relative position of weight and lifting machine to remain unchanged, and realizes the compensation of undulation function.
The utility model is realized permanent tension compensating by initiatively being combined with passive compensation, has improved scope and the corresponding speed of compensation of undulation, guarantees that corresponding steel rope is in certain tensioning state, keeps permanent tension force.
