Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
A kind of structural representation controlling the hydraulic wireline winch of submerged floating tension leg platform attitude that Fig. 1 provides for the embodiment of the present invention;
Fig. 2 is the partial enlarged drawing in Figure 1A portion.
Detailed description of the invention
See figures.1.and.2, a kind of hydraulic wireline winch controlling submerged floating tension leg platform attitude, comprises steel rope 1.Steel rope 1 scribble water insoluble, special slip coating free from environmental pollution, be coiled into stock and stock at steel rope 1 to be coiled in rope two processes and to carry out special brush coating process at twice, guarantee that coating can be coated onto between the silk of steel rope 1 and silk and between stock and stock sufficiently uniformly.Thus reduce the wearing and tearing of steel rope 1 and reel 3 and pulley room.Hydraulic wireline winch is arranged on can on the deck 2 of submerged floating tension leg platform, and hydraulic wireline winch comprises tension windlass and anchoring winch, and the quantity of tension windlass is four, and the quantity of anchoring winch is four, and tension windlass is identical with the structure of hydraulic wireline winch.Hydraulic wireline winch comprises reel 3, drum shaft stay bearing plate 4, bi-lug plate twisted branch seat twisted axis 5.Steel rope 1 is wrapped on reel 3, drum shaft 6 is installed in reel 3, drum shaft 6 is connected with drum shaft stay bearing plate 4, drum shaft stay bearing plate 4 is connected with bi-lug plate twisted branch seat 7 by bi-lug plate twisted branch seat twisted axis 5, bi-lug plate twisted branch seat 7 is connected with pedestal 8, pedestal 8 is fixed on the deck 2 of submerged floating tension leg platform, and the quantity of bi-lug plate twisted branch seat 7 is four.
Be dynamic seal (twice rotate general plug and seal) structure between drum shaft 6 and drum shaft stay bearing plate 4, two seal rings 9 are installed between the two.For ensureing that seal ring 9 should have the abrasion loss function with S. A. binding face in auto-compensation operation process, the U-shaped spring leaf 10 of corrosion-resistant steel is installed in seal ring 9.For strengthening the elasticity of the U-shaped spring leaf 10 of corrosion-resistant steel, elastic caoutchouc 11 is filled in the U-shaped chamber of the U-shaped spring leaf of corrosion-resistant steel 10, therefore seal ring 9 has the abrasion loss of seal ring 9 in auto-compensation operation process, ensure that the sealing property of seal ring 9 and is extending seal ring 9 service life.Be filled with water-fast anti-attrition lubricant food grade silicone 12 between two seal rings 9, food grade silicone 12 can reduce the abrasion loss of drum shaft 6 abradable seal circle 9 in reel 3 rotary course, plays lubricating effect, and is not melted into water.Epicyclic gear box 13 is installed in watertight reel, does not singly solve the sealing problem of gear case, take full advantage of the intracavity space of reel 3 simultaneously, reduce oad and the weight of hydraulic wireline winch.The input end of epicyclic gear box 13 is provided with hydraulic pressure diaphragm type drg (Zollern or equivalents).The drive end of drum shaft 6 installs motor watertight case 14, and motor watertight case 14 is connected with the deck 2 of submerged floating tension leg platform by support link 15.Bi-lug plate twisted branch seat twisted axis 5 is separately installed with two strain gauges 16, and the position of strain gauge 16 is near the rope-out end of steel rope 1.The signal output part of strain gauge 16 is connected with the signal input part of motor watertight case 14, and the signal output part of motor watertight case 14 is connected with the signal input part of computing machine, computer controlled hydraulic efficiency servo.The driven end of drum shaft 6 is provided with coder watertight case 17, and the signal output part of coder watertight case 17 is connected with the signal input part of computing machine, computer controlled hydraulic efficiency servo.Motor watertight case 16 and coder watertight case 17 lower end are provided with liquidometer mounting shaft 18, when infiltrating the current direction liquidometer mounting shaft 18 of motor watertight case 16 with coder watertight case 17, when in well, liquid level rises to setting value, liquid level switch sends alerting signal and reaches central station of floating dock.
When this device works, suffered load signal is reached motor watertight case 14 and gathers by strain gauge 16, and then reaches central station of floating dock computing machine.The steel rope 1 pulling force signal that this signal is scaled hydraulic wireline winch by computing machine shows on a display screen.Coder watertight case 17 inner drum 3 rotating speed and revolution signal are sent to central station of floating dock computing machine simultaneously, and this signal is converted to speed and the length signals that reel 3 is involved in or releases steel rope 1 by computing machine.Platform stance controller takes into account the dip compass information of land lengths direction and Width according to the immersed depth on platform deck 2, given each hydraulic wireline winch take-up speed and length.Again by signal that platform stance controller returns, by the master control direction valve (proportional reversing valve) of the main pumping station of computer controlled hydraulic wireline winch hydraulic efficiency pressure system, realized forward and backward and the infinite speed variation of HM Hydraulic Motor by controlling main reversing valve by proportional pressure-reducing valve.Computer controlled servo hydraulic system, is controlled flow and the flow velocity of the hydraulic oil of the hydraulic pressure diaphragm type drg respectively entering each hydraulic wireline winch, regulates lock torque and the braking time of electric-controlled hydraulic diaphragm type drg by servo hydraulic system.
