Abstract
A hydraulic sea wave compensation winch is a following system capable of leading a steel wire rope on a crane to rise and fall along with sea waves. The basic principle of the hydraulic sea wave compensation type winch includes that when a ship contacts with a water surface, the steel wire rope is loosened instantly due to support of buoyancy of water, a sensor mounted on a crane jib senses changes of tension of the steel wire rope instantly, accordingly a low-displacement mode is automatically selected, and a sea wave compensation function is activated. The steel wire rope is lifted up or placed down by the aid of the winch according to needs, so that the steel wire rope is in a tension state all along, the small ship changes along with the sea waves all along, and safety of the small ship and personnel on the small ship are ensured. In addition, the sea wave compensation type winch is driven by a hydraulic system and is sensitive in response, response time is shorter than 0.5s, maximum sea wave compensation speed can reach 100m/minute, maximum acceleration achieves 2m/s2, the small ship can be safely collected and released in a high sea state assuredly, and the rope is prevented from being broken.
Description
(1) technical field
The present invention relates to a kind of equipment that is installed on loop wheel machine, belong to the shipbuilding technology, a kind of specifically winch with wave compensate function for the confession crewman routine use that boats and ships and offshore work platform were equipped with.
(2) background technology
In high sea situation, belt speed is put under the ship situation, and can make canoe safe and reliable use under the impact of wave is an essential condition of present yawl.At present, the domestic winch overwhelming majority is a motorized motions, does not have the wave compensate function.When this had just caused under high sea situation operation, common winch received the wave huge impact, badly influences equipment and personnel's safety, and this puts ship to belt speed and has caused restriction.
(3) summary of the invention
The present invention has designed a kind of novel winch in order to solve above-mentioned restriction, to realize the wave compensate function.Fig. 1 is the overall structure scheme drawing.
Its know-why is: this device adopts hydraulic efficiency pressure system (Fig. 2) to drive, and the wave compensation speed can be followed the tracks of the variation of wave according to the real-time automatically regulating of the actual velocity of impact of wave.This winch can spur canoe through hydraulic efficiency pressure system (Fig. 2) and follow the rise and fall of wave constant speed steady acceleration, and makes the constant tension force of maintenance on the steel rope 6, to guarantee canoe safe folding and unfolding under high sea situation, prevents disconnected rope.
This winch has a band groove reel 7, is driven by gear case 3.Gear case 3 is driven by the HM Hydraulic Motor 5 of double amount.HM Hydraulic Motor 5 has two kinds of operational modes:
Winch promotes canoe at full capacity with the maximum line velocity of 20m/min.
The tension force of steel rope 6 can be adjusted to 500kg, and maximum linear velocity 100m/min realizes the wave compensate function.
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 6 becomes slack, and the pulling force on the steel rope 6 can be less than the permanent tension value of setting, and this switch can activate constant tension system.
Advantage of the present invention is that winch can spur canoe and follows the uniform accelerated motion of wave constant speed, and makes steel rope keep constant-tension, guarantees safety.

(5) specific embodiment
Accompanying drawings: among Fig. 3, permanent tension motor 5 can be realized quick forward and reverse rotation, and its rotative speed can be regulated according to hydraulic flow continuously.Gear case 3 is driven by double amount HM Hydraulic Motor 5.The selection of discharge capacity is confirmed by electromagnetic valve.Pump divides three positions to hydraulic efficiency pressure system (Fig. 2) fuel feeding, and first is a stop position, and second and the 3rd position are controlled the lifting and the decline of winch HM Hydraulic Motor 5 respectively.When motor 5 was in low discharge capacity pattern, system was low moment of torsion, high-speed state, and reel 7 drives through gear case 3 and obtains high speed revolutions and keep a less pulling force.When wave rise, when descending, steel rope 6 pulling canoes to be to rise, to descend with wave constant speed, steady acceleration, prevent that wave from dashing canoe to turn over.So just avoided producing instant impact on the steel rope, guaranteed that steel rope 6 is not broken.
Claims (2)
1. a wave offset-type loop wheel machine steel rope draw off gear is made up of reel, gear case and HM Hydraulic Motor, it is characterized in that: have the wave compensate function, make canoe can follow the fluctuations of wave.
2. loop wheel machine steel rope draw off gear according to claim 1 is characterized in that: but double amount HM Hydraulic Motor drive gear casing is realized lifting and decline, and through solenoid control hydraulic fluid flow rate size and then control lifting descending speed.
