Traction type reciprocator for single point mooring liquid slip ring test

Abstract

The invention belongs to marine engineering machinery, and relates to a traction type reciprocator for a single point mooring liquid slip ring test. The traction type reciprocator is characterized in that a hydraulic cylinder is arranged on a mounting platform; a cylinder piston A at one end of the hydraulic cylinder drives a traction pulley block A consisting of a pulley J, a pulley I, a pulley H, a pulley G, a pulley F, a pulley E, a pulley C and a pulley D through a steel wire rope; and a cylinder piston B at the other end of the hydraulic cylinder drives a traction pulley block B consisting of a pulley K, a pulley L, a pulley M, a pulley N, a pulley A and a pulley B through a steel wire rope, the pulley K and the pulley L are arranged on a support H, the pulley M and the pulley N are arranged on the support G, the pulley A is arranged on the support A, and the pulley B is arranged on the support B. The traction type reciprocator is reasonable in design and simple in structure; even if the rope of the pulley block on one side of the cylinder is stored, the rope of the pulley block on the other side of the cylinder is released, and then a reciprocating function of the reciprocator is realized; and moreover, the traction type reciprocator is easy to manufacture and maintain, low in failure rate, low in manufacturing cost, quite convenient to operate and use, simple, practical, safe and reliable, and the steel wire ropes are anti-slip.

Description

technical field [0001] The invention belongs to marine engineering machinery, in particular to a traction type reciprocating mechanism used for single-point mooring liquid slip ring test. Background technique [0002] As we all know, the single-point mooring fluid slip ring is one of the important equipment of the single-point mooring wharf. It is mainly installed on the wellhead of the subsea oil well, used to connect the oil pipeline and the oil well, and also has the function of anchoring the oil ship. . Because the single-point mooring fluid slip ring is used on the seabed, the environment is harsh, affected by wind, waves, and currents, and the upper and lower parts rotate relative to each other for a long time, so the single-point mooring fluid slip ring needs to be used before leaving the factory. A set of test equipment is used to test the tightness and reliability of the upper and lower halves. At present, the single-point mooring liquid slip ring test device usua...
