Problems solved by technology

The resistance generated by the mechanical damper is fixed in size and the applicable range is small. When the resistance is too small, the anti-fall effect cannot be achieved. When the damping is too large, additional external force is required to drag the disengaged part to drop and disengage, resulting in structural parts being damaged. Excessive force may even cause structural damage

Abstract

The invention discloses a hydraulic self-adaptive control system for an anti-falling device and a control method of the hydraulic self-adaptive control system. The hydraulic self-adaptive control system is not provided with a driving motor, cannot actively drive an external load to operate, only passively adapts to the change of the load, and utilizes the gravitational potential energy of separating from part of the load; the pressure energy and the kinetic energy are converted into pressure energy and kinetic energy of the hydraulic self-adaptive system. Therefore, the motion speed of the separated part load is controllable, and accelerated falling of the separated part load is prevented. Meanwhile, the hydraulic self-adaptive control system is high in load resistance and can adapt to changes of different loads in a large range, it is guaranteed that the pressure of the hydraulic system changes along with load force in a self-adaptive mode in the working range of equipment, and it is guaranteed that the anti-falling device controls the separated part of the loads to fall at the same set speed all the time.

Description

A hydraulic self-adaptive control system for anti-fall device and its control method technical field The invention belongs to the anti-falling device technical field of marine cryogenic hose conveying system, particularly a kind of anti-falling device for anti-falling A hydraulic self-adaptive control system for a landing device and a control method thereof. Background technique [0002] In recent years, with the rapid growth of offshore LNG exploitation and transshipment demand. An offshore cryogenic hose conveying system Get more and more applications. In order to adapt to harsh sea conditions, to deal with sudden emergencies such as long-distance drift between offshore transportation platforms situation, to achieve rapid disengagement of cryogenic hose conveying systems between platforms, usually increased in cryogenic hose conveying systems Emergency escape function. The cryogenic hose conveying system with emergency disengagement function is in the actual test...
