Description
Technical field
The present invention relates to a kind of lifting system of self-lifting well drilling platform gear automatic grease lubrication system, belong to self-elevating drilling platform technical field.
Background technique
Self-elevating drilling platform lowering or hoisting gear, by rack pinion, realizes spud leg rising hull and declines, or contrary motion.Because its distinctive large torque high strength.So gear nominal diameter is large, modulus is large and thickness is large (100mm and more than), and gear lines is intensive, and installation environment is that semi-open type space is little, adopts small gear lubrication to be difficult to realize by spatial constraints.Adopt grease lubrication, model is generally NLG, and viscosity is large, so general spray regime is not very desirable.The way of manually smearing lubricating grease is all adopted in current industry.But the lifting platform activity duration is long, intensity of workers is large, smears quality instability, affects lubrication effect.
Summary of the invention
The object of the invention is to the above-mentioned shortcoming for prior art, the invention provides a kind of large modulus for self-elevating drilling platform lowering or hoisting gear, the exposed gear grease lubrication device of large standard pitch diameter.
To achieve these goals, technological scheme of the present invention is as follows.
A kind of lifting system of self-lifting well drilling platform gear automatic grease lubrication system, comprise control unit and oil pump station, oil pump station is connected with oil separator, oil separator is connected with multiple fuel feeding branch road, fuel feeding branch road is connected with relief valve, relief valve rear portion is connected with spring type mechanical accumulator and solenoid valve, and control unit receives elevating system start stop signal and gear position signal and scarce fat feedback signal device, and controls opening and closing direction and the time of oil pump station and solenoid valve thus; Solenoid valve bottom is provided with by the gear of fat liquoring, is axially lifted with smears rubber by the parallel gears above the gear place of fat liquoring.
Further, solenoid valve is three position four-way electromagnetic valve, solenoid valve is provided with forward grease outlet and reverse grease outlet.
Further, smear rubber and adopt magnetic oil-resistant rubber material, smear on rubber and be provided with multiple oil duct.Under the effect of magnetic force, rubber and gear surface adhesive can be smeared, simultaneously in rotation process by the loose fat effect of rubber surface oil duct by grease uniform application to gear surface.
In this system, lubricant grease is expressed into oil separator by oil pump station, by the equal pressure of oil separator be assigned to ~ individual (requiring according to lubricating point) in fuel feeding branch road, its detailed process is:
(1) grease is expressed to oil separator by oil pump station unification, by each fuel feeding branch road of oil separator, grease is fed to each lubricating point, relief valve is at the end of each fuel feeding bypass duct, and pressure setting is 10MPa, to ensure that the fuel feeding consistent of each branch road is stablized.
(2) spring type mechanical accumulator ensures when closed electromagnetic valve, and in fuel feeding branch road, oil pressure overvoltage can not produce damage to equipment, and when solenoid valve is opened, lubricating grease can flow out under stress in time, drops into gear by the appropriate location of Surface of action.
(3) solenoid valve is three-position four-way valve, when can ensure the clockwise of gear and rotate counterclockwise, grease can both be coated onto at correct Surface of action.Corresponding oil outlet can be opened according to the positive hour hands of the job requirement of lowering or hoisting gear or counterclockwise, and adjust according to actual speed, opening and closing time of solenoid valve thus control application place and the oil quantity of grease.
(4) smear rubber, adopt magnetic oil-resistant rubber material.Tow sides have cloth deep-fried twisted dough sticks line and oil duct.So no matter gear is clockwise or rotate counterclockwise, and smears rubber and all can fit with face of gear under the effect of magnetic force, and by uniform for the grease Surface of action to gear in the process of rotating.
This beneficial effect of the invention is: fat is mended in this system energy self oiling, and the simple cost of structure is low.According to rising or the different operating mode of lower degradation, hydraulic fluid port can be adjusted, Surface of action lubricated.Lubricating grease is fuel-displaced avoids waste according to lifting action synchronization control, also reduces the pollution to ocean environment simultaneously.The dispersion smearing mechanism of lubricating grease is simple, and reliability is strong.
