Abstract
A sea wave compensation system which ensures safe work of a double hanging point boat retraction device is disclosed. Two independent passive hydraulic sea wave compensation winches are used to control the two hanging points respectively. A sensor is used to detect up and down of the sea wave. The winch packs up or sends out a steel wire rope according to up and down of the sea wave so that the steel wire rope is always in a tension state so as to prevent the device and personnel from impact. Two independent wave compensation functional winches ensure that the steel wire ropes in the two hanging points in different moving states are always in tension state under severe sea conditions.
Description
(1) technical field
The present invention is a kind of two suspension centre loop wheel machine design-calculated wave charging systems that aim at.
(2) technical background
At present, wave offset-type winch is the visual plant of boats and ships or platform folding and unfolding jolly boat or life boat, and the domestic winch overwhelming majority is a motorized motions, does not have the wave compensate function.Because the effect of wave, especially need be under high sea situation during operation, common winch will receive very large sea beat, has a strong impact on equipment and personnel's safety.Wave offset-type winch is that a cover can be followed the follow-up system that wave rises and falls; Its groundwork is the fluctuating of being measured wave by sensor; Steel rope is packed up or emitted to winch according to the fluctuating of wave, makes steel rope in tension all the time, thereby avoid equipment and personnel to be impacted.
The research and development of two suspension centre wave charging systems have limited the safe handling of two suspension centre canoe draw off gears.Two suspension centre wave charging systems belong to blank in China's technical field, have hindered the raising of shipbuilding industry general technical level.
(3) summary of the invention
In order to solve the safety issue of two suspension centre canoe draw off gear folding and unfoldings under high sea situation situation, the present invention has designed a kind of pair of system that suspension centre carries out the wave compensation respectively.
Technical scheme is: two passive type hydraulic waves compensation of this invention employing winches are controlled two suspension centres respectively and are carried out the wave compensation, and winch has a band groove reel, is driven by gear case.Gear case is by the fluid motor-driven of double amount.HM Hydraulic Motor has two kinds of operational modes:
Automatic selector switch from normal behaviour's ship pattern to permanent tension mode is arranged on every winch, and when the moment on canoe contact sea, steel rope becomes slack; Pulling force on the steel wire can be less than the permanent tension value of setting; This switch can activate constant tension system, and constant tension system is providing a pulling force less than canoe gravity all the time, when canoe during with ocean wave motion; This perseverance tension force will keep steel rope to tighten all the time, thereby realize the wave compensation of passive type.
The advantage of this invention is: make steel rope keep constant tension force.This means that the canoe that hangs on the canoe draw off gear can follow wave constant speed, uniform accelerated motion by the steel rope of tightening.Steel rope is followed canoe motion automatically, so do not have unexpected stressedly, has guaranteed under high sea situation situation the safety of two suspension centre canoe draw off gear work.

Among the figure 1, winch, 2, stand canoe state, 3, winch, 4, suspension centre, 5, canoe state on the sea, 6, suspension centre.
(5) specific embodiment
In conjunction with accompanying drawing 1 explanation; The two suspension centres of design-calculated of the present invention are charging system respectively; Drive 1,3 work of two passive type hydraulic waves compensation winches by Hydraulic Station, two winches can be respectively start the wave compensate function according to the situation of own the suspension centre of controlling 4,6.In actual use, the situation of canoe state 5 on the sea as shown in Figure 1 can appear in canoe, and suspension centre 4,6 is in different state of kinematic motions.To guarantee that in this case two steel ropes all are in tension, just necessarily require two winches to carry out separate wave compensation.Two winches among the present invention are to have separate charging system; Every winch decides the operation of wave compensate function respectively through the tension force that detects the steel rope that self drives; Thereby realized the compensation respectively of two suspension centres, guaranteed two steel ropes in tension constantly.
Claims (2)
1. the present invention is a kind of pair of suspension centre wave of canoe draw off gear design-calculated charging system.It is characterized in that: adopt two independently passive type hydraulic wave compensation winches,, be implemented in two steel ropes that are in the different motion state under the severe sea condition and all keep the state tightened all the time through two winches wave compensate function independently.
2. passive type hydraulic wave compensation winch according to claim 1; It is characterized in that: have slow speed of revolution, high pulling torque; High rotating speed, two kinds of mode of operations of little moment of torsion detect the conversion of the variation control winch pattern of steel rope upper pulling force through pulling force sensor, realize the wave compensate function.
