Description
Technical field
The invention belongs to oceanographic engineering machinery, particularly a kind of towed reciprocator for swinging mooring's liquid slip ring test.
Background technology
Well-known, swinging mooring's liquid slip ring is one of visual plant of single point mooring port, is mainly installed on the well head part of sub-sea drilled wells, for connecting oil pipeline and oil well, also has the effect of grappling oil transportation ship simultaneously.Because swinging mooring's liquid slip ring is used for seabed, bad environments, the impact of wind-engaging, wave, stream, between upper and lower semi-body, long-term load phase is to rotation, so swinging mooring's liquid slip ring is before dispatching from the factory, test battery device is needed to test the sealing of upper and lower semi-body and reliability.At present, swinging mooring's liquid slip ring test unit, usual employing traditional, the test unit that passes through, swinging mooring's liquid slip ring upper and lower semi-body test unit that the hoisting mechanism that it comprises the motor-driven be made up of motor, shaft coupling, speed reduction unit, detent, reel and wire rope drives; Directly be wrapped in by wire rope in test unit on the upper semi-body of swinging mooring's liquid slip ring, lower semi-body is fixed on basin bottom, tests.Existing test unit has following shortcoming:
1. the hoisting mechanism building block be made up of motor, shaft coupling, speed reduction unit, detent, reel and wire rope is many, and comparatively complicated, failure rate is high, and reliability is low;
2. easily occur skidding between wire rope and swinging mooring's liquid slip ring;
3. manufacture and maintenance cost higher.
Summary of the invention
The present invention is intended to the shortcoming and defect part existed in above-mentioned technology, and provides a kind of towed reciprocator of testing for swinging mooring's liquid slip ring driven by hydraulic jack; This towed reciprocator is not only reasonable in design, compact conformation, when both having made the pulley blocks storage rope of oil cylinder side, the pulley blocks of opposite side puts rope, realize its reciprocalfunction, prevent again the skidding between wire rope and swinging mooring's liquid slip ring, both instead of the storage rope of traditional roll type and put rope; Be easy to again manufacture, safeguard, and have simple and practical, failure rate is low, safe and reliable, low cost of manufacture and operation use the advantages such as very convenient.
The object of the invention is to adopt following technical scheme to realize: the described towed reciprocator for swinging mooring's liquid slip ring test, comprise swimmer's pool, swinging mooring's liquid slip ring upper semi-body, swinging mooring's liquid slip ring lower semi-body and wire rope, it is characterized in that: the hydraulic jack of installing band I bearing on mounting platform, the first oil cylinder piston of described hydraulic jack one end passes through the first haul-in sheave group of Steel rope drive; The second oil cylinder piston of its hydraulic jack other end, by Steel rope drive second haul-in sheave group, the mounting platform consistent with the axial line of hydraulic jack is sequentially installed the second haul-in sheave group be made up of the B pulley of the A pulley on the M pulley on the K pulley on H bearing and L pulley, G bearing and N pulley, A bearing, B bearing; The mounting platform consistent with hydraulic jack axial line is sequentially installed the first haul-in sheave group be made up of the D pulley on F pulley, the E pulley on E bearing, the C pulley on C bearing and the D bearing on the H pulley on the J pulley on J bearing and I pulley, K bearing and G pulley, F bearing; One end of described wire rope is A end, its other end is B end, the A of this wire rope end is fixed on the outer end of J bearing, and make the B of wire rope hold sequentially walk around H pulley, I pulley, G pulley, J pulley, F pulley, E pulley, C pulley, D pulley, on swinging mooring's liquid slip ring upper semi-body be wound around 3 circle after, after sequentially walking around B pulley, A pulley, K pulley, N pulley, L pulley and M pulley again, wire rope B end is fixed on H bearing the inner; Realize the to-and-fro movement of hydraulic jack by Steel rope drive first, second haul-in sheave group.
Principle of work of the present invention is described below:
The oil supply system consisted of house steward, solenoid valve and two arms Hydraulic Station due to the present invention drives oil cylinder reciprocating to move; When first oil cylinder piston moves right relative to hydraulic jack, the A end of I pulley, J pulley, J bearing and wire rope moves right, wire rope is sequentially by F pulley, E pulley, C pulley and D pulley, swinging mooring's liquid slip ring upper semi-body is pulled to operate clockwise relative to swinging mooring's liquid slip ring lower semi-body, meanwhile, K pulley, L pulley, H bearing and wire rope B end also moves right.When oil cylinder piston relative to hydraulic jack to left movement time, the B end of K pulley, L pulley, H bearing and wire rope is to left movement, wire rope is sequentially by A pulley and B pulley, swinging mooring's liquid slip ring upper semi-body is pulled to transport counterclockwise relative to swinging mooring's liquid slip ring lower semi-body, meanwhile, the A end of I pulley, J pulley, J bearing and wire rope is to left movement.When realizing the pulley blocks storage rope of hydraulic jack side, the pulley blocks of hydraulic jack opposite side puts rope, finally realizes the to-and-fro movement of test unit.
The comprehensive above technical scheme taked, realizes object of the present invention.
The present invention has following feature:
1., by the rational deployment of oil cylinder and pulley, when realizing the pulley blocks storage rope of oil cylinder side, the pulley blocks of opposite side puts rope, replaces relying on the storage rope at the two ends of reel in traditional form and putting rope, realize reciprocalfunction with this;
2. be fixedly wrapped in the wire rope middle part on swinging mooring's liquid slip ring upper semi-body by pressing plate, realize whole mechanism in the course of the work, wire rope relatively and swinging mooring's liquid slip ring do not skid.
Therefore the present invention is not only reasonable in design, and structure is simple, when both having made the pulley blocks storage rope of oil cylinder side, the pulley blocks of opposite side puts rope, realize its reciprocalfunction, prevent again the skidding between wire rope and swinging mooring's liquid slip ring, both instead of the storage rope of traditional roll type and put rope; Be easy to again manufacture, safeguard, and have simple and practical, failure rate is low, safe and reliable, low cost of manufacture and operation use the advantages such as very convenient.
