Description
Technical field
The present invention relates to the ancillary system of hand winch hydraulic control system peculiar to vessel, is the system that a kind of instrument and equipment that maintains on the winch for ship wirerope at the uniform velocity descends specifically.
Background technology
During oceanographic survey, when sea situation is good, preceding postpone to draw handle the control cock handle, decline or rising (at the uniform velocity gathering data with decline during oceanographic survey) that the instrument and equipment that wirerope hung can be at the uniform velocity reach the purpose of normal collection data.When sea situation is abominable; Boats and ships pitch, though the winch wirerope is at the uniform velocity to descend, measuring instrument equipment no longer is at the uniform velocity to descend; Can not descend or rise on the contrary or quicken and descend; This moment, survey data just can not reach the effect of actual anticipation, and the investigator will stop investigation, influenced the integraty of data.
Summary of the invention
The purpose of this invention is to provide the system that a kind of instrument and equipment that maintains on the winch for ship wirerope at the uniform velocity descends, to overcome the deficiency of prior art.
The present invention is on the basis of existing hand winch hydraulic control system peculiar to vessel (manually actuated control valve); When working more than the sea situation level Four; Though the winch wirerope at the uniform velocity descends; Measuring instrument equipment on the winch wirerope loses normal decline state because surge to rise and fall; Consider that at the uniform velocity the descending of measuring instrument that boats and ships jolt on the winch that is produced is the restriction that receives the hand winch hydraulic control system, in the special winch for ship hydraulic oil pump system in the hydraulic oil pump room, be provided with a power assist system of utilizing boats and ships to jolt and produced; Reach the deficiency of compensation hand winch hydraulic control system, thus make the winch wirerope and the measuring instrument equipment hung basically can be normally the purpose of decline at the uniform velocity.Be that groundwork of the present invention is to utilize pitching of boats and ships, making pendulum is that the center generation swings as power with the arm shaft.When pendulum is turned left swing, open incremental control valve, the hydraulic fluid flow rate in the incremental control valve is increased, promote HM Hydraulic Motor and quicken with pendulum arm upper end; Pendulum is turned right when swinging, and then closes to subtract flow-controlling gate, and the flow that subtracts flow-controlling gate hydraulic oil is reduced, and the HM Hydraulic Motor rotating speed reduces, and reaches the instrument and equipment that maintains on the winch for ship wirerope and at the uniform velocity descends.
Technical scheme of the present invention includes manually actuated control valve, handle, HM Hydraulic Motor, hydraulic oil pump and pipeline, it is characterized in that it also comprises by means of the shell that is bolted to hydraulic oil pump one side; Be fixed with on the arm shaft that is provided with in the shell pendulum arm and under pendulum and setting nut; The outer casing inner wall both sides are fixed with the right stop and the left stop of pendulum; Wall top is fixed with the incremental control valve of oil outlet pipe, oil inlet respectively in the enclosure again; With the flow-controlling gate that subtracts that oil inlet, oil outlet pipe are arranged, oil outlet pipe connects oil pipe through check valve, and oil inlet connects oil pump outlet line via normally closed solenoid valve; The oil inlet that subtracts flow-controlling gate connects on the oil pipe of normally open solenoid valve upper end, and the oil outlet pipe of incremental control valve is connected on the oil pipe of normally open solenoid valve lower end via check valve.Obviously, the installation site of shell of the present invention and stem are to relevant.
The present invention is rational in infrastructure, and technology is simple, when the abominable boats and ships of sea situation pitch, makes measuring instrument on the winch wirerope of boats and ships remain a constant speed to descend and reaches the effect of actual anticipation, and assurance investigation is normally carried out and obtained complete information.

The specific embodiment
Like Fig. 1; The present invention includes manually actuated control valve 20, handle 21, HM Hydraulic Motor 22, hydraulic oil pump 24 and pipeline, it is characterized in that it also comprises the shell 9 that is fixed on hydraulic oil pump 24 1 sides by means of bolt 27; Be fixed with on the arm shaft 26 that is provided with in the shell 9 pendulum arm 3 and under pendulum 4 and setting nut 25; Shell 9 inwall both sides are fixed with the right stop 5 and left stop 6 of pendulum 4, and what above shell 9 inwalls, be fixed with the incremental control valve 1 of oil outlet pipe 11, oil inlet 28 again respectively and oil inlet 10, oil outlet pipe 12 arranged subtracts flow-controlling gate 8; Oil outlet pipe 12 connects oil pipe 18 through check valve 15, and oil inlet 28 connects oil pump outlet line 13 via normally closed solenoid valve 14; The oil inlet 10 that subtracts flow-controlling gate 8 connects on the oil pipe 18 of normally open solenoid valve 17 upper ends, and the oil outlet pipe 11 of incremental control valve 1 is connected on the oil pipe 18 of normally open solenoid valve 17 lower ends via check valve 16.
Above-mentioned flow-controlling gate 1,8 and normally open solenoid valve 17 are the commercially available prod with normally closed solenoid valve 14.
Technically, the weight of the length of fixing pendulum arm 3 and pendulum 4 should be enough to guarantee to open when boats and ships pitch incremental control valve 1 and subtract flow-controlling gate 8 on the above-mentioned central arm shaft 26.
During use, the present invention is installed in the hydraulic oil pump room.Marine investigation runs into sea situation when good, check valve 15 and check valve 16 be stop hydraulic oil flow to incremental control valve 1 with subtract flow-controlling gate 8 and make the winch can normal operation.When boats and ships pitched, opened normally closed solenoid valve 14, shut normally open solenoid valve 17, when bow is downward this moment; Stern perk (general winch is placed on aft deck), instrument and equipment does not descend and rises on the contrary, and this moment, pendulum 4 beginnings were toward the ship's head swing; Drive pendulum arm 3 and push valve handle 2 to valve opening position; The fuel tap of incremental control valve 1 is opened, and hydraulic oil quickens HM Hydraulic Motor 22 through normally closed solenoid valve 14 turnover oil pipes 12 through incremental control valve 1 and check valve 16; Remedy the distance that produces because of Ship Swaying, thereby instrument and equipment is at the uniform velocity descended.When bow made progress, under the stern-on, instrument and equipment quickened to descend; Pendulum 4 beginning this moment drives pendulum arm 3 and lets valve handle 7 to closing direction toward the swing of stern direction, makes to subtract flow-controlling gate 8 and turn down fuel tap; Hydraulic oil is prevented from a part; HM Hydraulic Motor 22 is slowed down, reduce the distance that increases because of Ship Swaying, thereby instrument and equipment is at the uniform velocity descended.
