Abstract
The invention relates to a hydraulic system with a buffer function. The hydraulic system comprises a buffer cylinder, a piston rod and a cartridge valve system, wherein the piston rod is arranged in the buffer cylinder; the buffer cylinder is connected with an oil port of the cartridge valve system through an oil pipe; a control oil path between the buffer cylinder and the cartridge valve system is provided with a reversing valve and a one-way throttle valve; the reversing valve and the one-way throttle valve are connected in parallel. Since the hydraulic system with the buffer function is provided with the reversing valve and the one-way throttle valve, the reversing valve and the one-way throttle valve can achieve the purpose of buffer by controlling the throughput of hydraulic oil in the buffer cylinder; the hydraulic system with the buffer function has the advantages of simple structure, convenience in operation, flexibility in adjustment, safety, reliability and reduced cost and has good business prospect.
Description
Technical field
The present invention relates to the hydraulic system field, especially a kind of hydraulic system with pooling feature for quick gate hydraulic headstock gear.
Background technique
The buffer structure of existing quick gate hydraulic headstock gear is mechanical buffer structure, is by cushion collar, and buffering ring, restricting orifice form, and there are following several shortcomings in such buffering form: at first, cushion collar belongs to the parts of thin-walled type, and length is longer, processing difficulties, yielding; The second, between cushion collar and buffering ring, be transition fit, because the distortion of cushion collar, oil cylinder is when operation, cushion collar enters in the process of buffering ring easily stuck, makes the working time of oil cylinder long; The 3rd, restricting orifice is to be installed on the lower end cap of oil cylinder, can't test the pooling feature of restricting orifice in the process of the test of oil cylinder, can only be on-the-spot equipped, and, after the oil cylinder installation in position, the replacing difficulty of restricting orifice is larger.
Summary of the invention
The technical problem to be solved in the present invention is: for a kind of hydraulic system with pooling feature is provided, and easily processing, easy to operate, cost is lower.
The technical solution adopted for the present invention to solve the technical problems is: a kind of hydraulic system with pooling feature, comprise cushion dashpot, piston rod and cartridge valve system, described piston rod is arranged in cushion dashpot, described cushion dashpot is connected with the hydraulic fluid port of cartridge valve system by oil pipe, on oil circuit control between described cushion dashpot and cartridge valve system, selector valve and one-way throttle valve are installed, described selector valve and one-way throttle valve are arranged in parallel.Reach the purpose of buffering by selector valve and one-way throttle valve.
Described selector valve is solenoid directional control valve, when piston rod stretches out, electromagnet in selector valve obtains electric, hydraulic oil is simultaneously by selector valve and one-way throttle valve, when piston rod runs to the buffer position of setting, the electromagnet dead electricity in selector valve, hydraulic oil only passes through one-way throttle valve, thus, reach the purpose of buffering by the throughput that reduces hydraulic oil.
The invention has the beneficial effects as follows: the present invention has the hydraulic system of pooling feature owing to being provided with selector valve and one-way throttle valve, selector valve and one-way throttle valve can be controlled the purpose that the throughput of hydraulic oil in cushion dashpot reaches buffering, simple in structure, easy to operate, flexible adjustment, safe and reliable, reduced cost, there is good commercial promise.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the perspective view of a preferred embodiment of the hydraulic system of the present invention with pooling feature;
In figure: 1. cushion dashpot, 2. piston rod, 3. selector valve, 4. one-way throttle valve.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of hydraulic system with pooling feature, comprise cushion dashpot 1, piston rod 2 and cartridge valve system, described piston rod 2 is arranged in cushion dashpot 1, described cushion dashpot 1 is connected with the hydraulic fluid port of cartridge valve system by oil pipe, selector valve 3 and one-way throttle valve 4 are installed on the oil circuit control between described cushion dashpot 1 and cartridge valve system, and described selector valve 3 and one-way throttle valve 4 are arranged in parallel.
Described selector valve 3 is solenoid directional control valve, and when piston rod 2 stretches out, the electromagnet in selector valve 3 obtains electric, when piston rod 2 runs to the buffer position of setting, and the electromagnet dead electricity in selector valve 3.
Add man-hour, piston rod 2 stretches out cushion dashpot 1, and the electromagnet in selector valve 3 obtains electric, and selector valve 3 and one-way throttle valve 4 are opened simultaneously, and the oil circuit control of hydraulic oil on selector valve 3 and one-way throttle valve 4 that the cartridge valve hydraulic fluid port flows out enters in cushion dashpot 1 simultaneously; When piston rod 2 runs to the buffer position of setting, electromagnet dead electricity in selector valve 3, selector valve 3 cuts out, the hydraulic oil that the cartridge valve hydraulic fluid port flows out can only enter in cushion dashpot 1 by the oil circuit control on one-way throttle valve 4, make the hydraulic oil entered in cushion dashpot 1 reduce, thereby reach the purpose of buffering.
Compared with prior art, the present invention has the hydraulic system of pooling feature owing to being provided with selector valve 3 and one-way throttle valve 4, the throughput that selector valve 3 and one-way throttle valve 4 can be controlled cushion dashpot 1 interior hydraulic oil reaches the purpose of buffering, simple in structure, easy to operate, flexible adjustment, safe and reliable, reduce cost, there is good commercial promise.
The above-mentioned foundation desirable embodiment of the present invention of take is enlightenment, and by above-mentioned description, the relevant staff can, in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to the claim scope.
