Description
Technical field
The present invention relates to a kind of hydraulic system, specifically fairlead float support hydraulic system, is particularly suitable for use in
Scientific investigation class winch.
Background technology
Winch is a kind of small-sized crane gear that hawser lifting or traction are wound with reel, also known as hoist engine.For
Convenience typically can all set fairlead into and out of hawser on winch.At present, fairlead is directly anchored on winch
, this causes fairlead angle not change.However, in actual use, winch storage rope device into and out of rope position one
As can go up, change so that it is inconsistent into and out of rope position and the height of the fairlead of fixed installation, occur tilting into and out of rope
Situation, causes hawser to occur unnecessary friction with Dao Lanlun mechanisms, accelerates the rate of wear of hawser, shortens the use longevity of hawser
Life.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of fairlead float support hydraulic system, the hydraulic pressure is used
System can change the mounting means of fairlead and winch, it is to avoid unnecessary friction, so as to extend the service life of hawser.
To solve the above problems, providing following technical scheme：
The characteristics of fairlead float support of the present invention is with hydraulic system is to include support cylinder and subtract relief valve.The support
The rod chamber of oil cylinder has the first hydraulic fluid port, rodless cavity to have the second hydraulic fluid port, and subtracting relief valve has first interface, second interface and drain tap.
First hydraulic fluid port of the support cylinder is connected with oil return box by pipeline, and the second hydraulic fluid port of the support cylinder is by pipeline with subtracting
The first interface of relief valve is connected, and the drain tap for subtracting relief valve is connected with draining case by pipeline, subtracts the second interface of relief valve
Oil feeding reservoirs is connected with by pipeline.
Wherein, there is magnetic valve on described that segment pipe subtracted between the second interface of relief valve and oil feeding reservoirs.
Above scheme is taken, with advantages below：
Because the fairlead float support hydraulic system of the present invention includes support cylinder and subtracts relief valve, support cylinder has
Rod cavity has the first hydraulic fluid port, rodless cavity to have the second hydraulic fluid port, and subtracting relief valve has first interface, second interface and drain tap, support cylinder
The first hydraulic fluid port oil return box is connected with by pipeline, the second hydraulic fluid port of support cylinder passes through pipeline and the first interface for subtracting relief valve
It is connected, the drain tap for subtracting relief valve is connected with draining case by pipeline, and the second interface for subtracting relief valve is connected with confession by pipeline
Fuel tank.During installation, one end of fairlead and winch are hinged, support cylinder and winch that the other end passes through the hydraulic system
It is hinged.In use, oil feeding reservoirs enters fluid by subtracting the second interface and first interface of relief valve the rodless cavity of oil cylinder
In, it is arranged as required to subtract relief valve pressure value, the deadweight of fairlead can just be overcome by making the thrust of oil cylinder.Filled when leading cable
Put because external force move downward when, hydraulic oil enters draining by subtracting relief valve first interface, drain tap in the rod chamber of oil cylinder
In case, when fairlead is moved upwards because of external force, hydraulic oil enters oil return box by the first hydraulic fluid port in the rod chamber of oil cylinder
In so that fairlead is in quick condition all the time.Winch storage rope device into and out of rope position occur upper and lower variation when, become movable property
Raw pulling force can adjust the angle of fairlead rapidly so that into and out of highly consistent, the elimination inclination of rope position and fairlead
Into and out of rope phenomenon, it is to avoid unnecessary friction, the service life of hawser is extended.
Brief description of the drawings
Fig. 1 is the structure principle chart of the fairlead float support hydraulic system of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in figure 1, the fairlead float support hydraulic system of the present invention includes support cylinder 1 and subtracts relief valve 3.
The rod chamber of the support cylinder 1 has the first hydraulic fluid port A1, rodless cavity to have the second hydraulic fluid port A2, and subtracting relief valve 3 has first interface B1,
Two interface B2 and drain tap L.First hydraulic fluid port A1 of the support cylinder 1 is connected with oil return box 2, the support cylinder by pipeline
1 the second hydraulic fluid port A2 is connected by pipeline with subtracting the first interface B1 of relief valve 3, and the drain tap L for subtracting relief valve 3 is connected by pipeline
Draining case 4 is connected to, the second interface B2 for subtracting relief valve 3 is connected with oil feeding reservoirs 6 by pipeline.It is described to subtract the second of relief valve 3 and connect
There is magnetic valve 5 on that segment pipe between mouth B2 and oil feeding reservoirs 6.
During installation, one end of fairlead and winch are hinged, the other end by the support cylinder 1 of the hydraulic system with
Winch is hinged.During work, magnetic valve 5 obtains electric in normal open state, and oil feeding reservoirs 6 connects fluid by subtracting the second of relief valve 3
Mouth B2 and first interface B1 is entered in the rodless cavity of support cylinder 1, is arranged as required to subtract the pressure value of relief valve 3, is made support
The thrust of oil cylinder 1 can just overcome the deadweight of fairlead.When fairlead is moved downward because of external force, support cylinder 1
Hydraulic oil is entered in draining case 4 by subtracting the first interface B1 of relief valve 3, drain tap L in rod chamber, when fairlead is because of external force
Upwards during motion, hydraulic oil is entered in oil return box 2 by the first hydraulic fluid port A1 in the rod chamber of support cylinder 1 so that lead cable dress
Put and be in quick condition all the time.
