Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
A kind of structural representation that can accurately control 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 of Figure 1A section.
The specific embodiment
See figures.1.and.2, a kind of hydraulic wireline winch that can accurately control submerged floating tension leg platform attitude comprises steel rope 1.Scribble water insoluble on steel rope 1, special slip coating free from environmental pollution, be coiled into strand and thigh carries out special brushing technique in being coiled into two processes of rope at twice at steel rope 1, guarantee between silk that coating can be coated onto steel rope 1 sufficiently uniformly and silk and strand and thigh between.Thereby the wearing and tearing of steel rope 1 with reel 3 and pulley room have been reduced.But hydraulic wireline winch is arranged 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 the structure of tension windlass and hydraulic wireline winch is identical.Hydraulic wireline winch comprises reel 3, drum shaft stay bearing plate 4, ears 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 ears plate twisted branch seat 7 by ears plate twisted branch seat twisted axis 5, ears 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 ears plate twisted branch seat 7 is four.
For dynamic seal (the general plug sealing of twice rotation) structure, two seal rings 9 are installed between the two between drum shaft 6 and drum shaft stay bearing plate 4.For guaranteeing that seal ring 9 should have in the auto-compensation operation process abrasion loss function with the S. A. binding face, is equipped with the U-shaped spring leaf 10 of corrosion-resistant steel in seal ring 9.For strengthening the elasticity of the U-shaped spring leaf 10 of corrosion-resistant steel, fill elastic caoutchouc 11 in the U-shaped chamber of the U-shaped spring leaf 10 of corrosion-resistant steel, therefore seal ring 9 has the abrasion loss of seal ring 9 in the auto-compensation operation process, in the sealing property that has guaranteed seal ring 9 with extended 9 service lifes of seal ring.Be filled with water-fast anti-attrition lubricant food stage silica gel 12 between two seal rings 9, food stage silica gel 12 can reduce the abrasion loss of drum shaft 6 wearing and tearing seal rings 9 in reel 3 rotary courses, plays lubricating effect, and is not melted into water.Epicyclic gear box 13 is installed in the watertight reel, has not singly solved the sealing problem of gear case, take full advantage of simultaneously the intracavity space of reel 3, reduced oad and the weight of hydraulic wireline winch.The input end of epicyclic gear box 13 is equipped with hydraulic pressure diaphragm type drg (Zollern or equivalents).The drive end of drum shaft 6 is installed 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.Be separately installed with two strain gauges 16 on ears plate twisted branch seat twisted axis 5, 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, the computer controlled hydraulic efficiency servo.The driven end of drum shaft 6 is equipped 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, the computer controlled hydraulic efficiency servo.Motor watertight case 16 is equipped with liquidometer mounting shaft 18 with coder watertight case 17 lower ends, when infiltrating the current direction liquidometer mounting shaft 18 of motor watertight case 16 with coder watertight case 17, when in well, liquid level rose to setting value, liquid level switch sent alerting signal and reaches central station of floating dock.
When the work of this device, strain gauge 16 reaches motor watertight case 14 with suffered load signal and gathers, and then reaches the central station of floating dock computing machine.The steel rope 1 pulling force signal that computing machine is scaled this signal hydraulic wireline winch is showing screen display.Coder watertight case 17 inner drum 3 rotating speeds and revolution signal are sent to the central station of floating dock computing machine simultaneously, and computing machine converts this signal to speed and length signals that reel 3 is involved in or emits steel rope 1.The platform stance controller is taken into account the dip compass information of land lengths direction and Width, given each hydraulic wireline winch take-up speed and length according to the immersed depth on 2 of platform decks.The signal that returns by the platform stance controller again, the master control direction valve (proportional reversing valve) of the main pumping station by computer controlled hydraulic wireline winch hydraulic efficiency pressure system is realized forward and backward and the infinite speed variation of HM Hydraulic Motor by controlling main reversing valve by proportional pressure-reducing valve.The computer controlled servo hydraulic system is controlled flow and the flow velocity of the hydraulic oil of the hydraulic pressure diaphragm type drg that respectively enters each hydraulic wireline winch by servo hydraulic system, regulate lock torque and the braking time of electric-controlled hydraulic diaphragm type drg.
