The technical problem that the present invention will solve provides a kind of hydraulically powered permanent the pressure of the drill automatic bit feed and controls system, and this system has realized that permanent the pressure of the drill automatic bit feed function is driven on the top in the drilling process.
The technical scheme that the present invention taked is: a kind of hydraulically powered permanent the pressure of the drill automatic bit feed is controlled system, comprises load sensing variable pump, plug-in mounting reducing valve I, plug-in mounting overflow valve I, plug-in mounting overflow valve II and plug-in mounting reducing valve II; Load sensing variable pump intake links to each other with fuel tank; Outlet patches the A mouth of dress reducing valve I and the B mouth of plug-in mounting reducing valve II respectively; The B mouth of plug-in mounting reducing valve I links to each other with the cavity of resorption hydraulic fluid port of oil cylinder, links to each other with the inlet A of plug-in mounting overflow valve I simultaneously, and the outlet B of plug-in mounting overflow valve I links to each other with fuel tank; The control mouth X of plug-in mounting overflow valve I links to each other with the inlet of pressure valve; The inlet of the outlet of pressure valve and straight moving overflow valve I, a control of shuttle valve mouthful link to each other with the T mouth of plug-in mounting reducing valve I, and directly the outlet of moving overflow valve I links to each other with fuel tank, and the A mouth of plug-in mounting overflow valve I is connected through damping hole with controlling between the mouth X; The outlet A of plug-in mounting reducing valve II links to each other with the inlet A of oil cylinder epicoele hydraulic fluid port with plug-in mounting overflow valve II; The outlet B of plug-in mounting overflow valve II links to each other with fuel tank, controls mouthful X and links to each other with the A mouth through damping hole, and drain tap Y links to each other with the inlet that directly moves overflow valve II with another control mouth of shuttle valve, the control mouth of plug-in mounting reducing valve II; The outlet of straight moving overflow valve II is connected with fuel tank, and the outlet of shuttle valve links to each other with the control mouth of load sensing variable pump.
The invention has the beneficial effects as follows: the present invention has been owing to adopted the load sensing hydraulic control technology and two logical cartridge valve control technologys, realized oil cylinder under different conditions on carry or transfer, thereby have to push up in the drilling process and drive permanent the pressure of the drill automatic bit feed function.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
Shown in accompanying drawing, a kind of hydraulically powered permanent the pressure of the drill automatic bit feed is controlled system, comprises load sensing variable pump 1, plug-in mounting reducing valve I 2, plug-in mounting overflow valve I 6, plug-in mounting overflow valve II7 and plug-in mounting reducing valve II9; The intake of load sensing variable pump 1 links to each other with fuel tank; Outlet patches the A mouth of dress reducing valve I 2 and the B mouth of plug-in mounting reducing valve II9 respectively; The B mouth of plug-in mounting reducing valve I 2 links to each other with the cavity of resorption hydraulic fluid port of oil cylinder, links to each other with the inlet A of plug-in mounting overflow valve I 6 simultaneously, and the outlet B of plug-in mounting overflow valve I 6 links to each other with fuel tank; The control mouth X of plug-in mounting overflow valve I 6 links to each other with the inlet of pressure valve 4; The inlet of the outlet of pressure valve 4 and straight moving overflow valve I 3, a control of shuttle valve 5 mouthful link to each other with the T mouth of plug-in mounting reducing valve I 2, and directly the outlet of moving overflow valve I 3 links to each other with fuel tank, and the A mouth of plug-in mounting overflow valve I 6 is connected through damping hole with controlling between the mouth X; The outlet A of plug-in mounting reducing valve II9 links to each other with the inlet A of oil cylinder epicoele hydraulic fluid port with plug-in mounting overflow valve II7; The outlet B of plug-in mounting overflow valve II7 links to each other with fuel tank, controls mouthful X and links to each other with the A mouth through damping hole, and drain tap Y links to each other with the inlet that directly moves overflow valve II8 with another control mouth of shuttle valve 5, the control mouth of plug-in mounting reducing valve II9; The outlet of straight moving overflow valve II8 is connected with fuel tank, and the outlet of shuttle valve 5 links to each other with the control mouth of load sensing variable pump 1.
Drilling well is under the automatic bit feed state, and the stress of oil cylinder piston will determine it to carry or transfer on being.If directly the setting pressure of moving overflow valve I 3 is higher than the setting pressure of straight moving overflow valve II8; Hydraulic oil will flow into the rodless cavity of oil cylinder from load sensing variable pump 1 through plug-in mounting reducing valve I 2 so; Rod chamber oil will flow back to fuel tank through plug-in mounting overflow valve I 6, carries on the oil cylinder like this.Increase the pressure of straight moving overflow valve I 3, the valve port of plug-in mounting reducing valve I 2 will increase, and according to the principle of load sensing controlled, the discharge capacity of load sensing variable pump 1 increases, and flow strengthens, and that carries on the oil cylinder speeds up.If directly the setting pressure of moving overflow valve I 3 is lower than the setting pressure of straight moving overflow valve II8; Hydraulic oil will flow into the rod chamber of oil cylinder from load sensing variable pump 1 through plug-in mounting reducing valve II9 so; Rodless cavity oil will flow back to fuel tank through plug-in mounting overflow valve II7, and oil cylinder is transferred like this.Increase the pressure of straight moving overflow valve II8, the valve port of plug-in mounting reducing valve II9 will increase, and according to the principle of load sensing controlled, the discharge capacity of load sensing variable pump 1 increases, and flow strengthens, and what oil cylinder was transferred speeds up.
It is understandable that; More than about specific descriptions of the present invention; Only be used to the present invention is described and be not to be subject to the described technical scheme of the embodiment of the invention; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the present invention, to reach identical technique effect; As long as satisfy the use needs, all within protection scope of the present invention.
