Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, Figure 2 and Figure 3, a kind of hydraulic support column double-liquid-injectsystem system of the present invention, comprises piston 8 and the back-moving spring of post 1 alive, middle cylinder 1, middle cylinder 23, setting prop triple-use valve seat 4, setting prop triple-use valve 5, setting prop passage 6, oil cylinder 7 and middle cylinder two; Post 1 of living is sleeved in middle cylinder 1, and middle cylinder 1 is enclosed within middle cylinder 23, and middle cylinder 23 is sleeved in oil cylinder 7 inner chamber; Setting prop triple-use valve seat 4 lower end is connected with oil cylinder 7 by steel wire, upper end and middle cylinder 23 slipper seal, and setting prop triple-use valve 5 is assemblied on setting prop triple-use valve seat 4, also comprises prop drawing passage 9, prop drawing triple-use valve 10, prop drawing triple-use valve seat 11 and long-range liquid injection system; Described setting prop passage 6 is the passages being arranged on oil cylinder 7 pars intramuralis, prop drawing triple-use valve seat 11 top and middle cylinder 23 slipper seal, and bottom connects oil cylinder 7; Prop drawing triple-use valve 10 is assemblied in prop drawing triple-use valve seat 11 li, the end face of the piston 8 of cylinder two during prop drawing passage 9 is arranged on middle cylinder 23 outer wall and is also communicated with in the passage between oil cylinder 7 inwall; Described long-range liquid injection system comprises three way cock 12, high-pressure rubber pipe 13, liquid injecting mouth 14 and discharge mechanism 15, three way cock 12 connects liquid injecting mouth 14 and discharge mechanism 15 respectively by two high-pressure rubber pipes 13, liquid injecting mouth 14 dock setting prop triple-use valve 5 fluid injection end simultaneously discharge mechanism 15 dock prop drawing triple-use valve 10 and unload end or liquid injecting mouth 14 docks prop drawing triple-use valve 10 fluid injection end, discharge mechanism 15 docks setting prop triple-use valve 5 and unloads end.
Further, prop drawing triple-use valve seat 11 position, higher than setting prop triple-use valve seat 4 position, can make to produce larger pressure during prop drawing fluid injection.
Hydraulic prop is when setting prop, liquid injecting mouth 14 docks the fluid injection end of setting prop triple-use valve 5, discharge mechanism 15 docks the unloading end of prop drawing triple-use valve 10 simultaneously, hydraulic oil injects setting prop passage 6 by liquid injecting mouth 14 through setting prop triple-use valve 5, enter bottom cylinder 23, live post 1, middle cylinder 1 and middle cylinder 23 stretch out successively until rise to the height met the demands.
Hydraulic prop is when prop drawing, and liquid injecting mouth 14 docks the fluid injection end of prop drawing triple-use valve 10, and discharge mechanism 15 docks the unloading end of setting prop triple-use valve 5; Hydraulic oil injects in prop drawing passage 9 by liquid injecting mouth 13 through prop drawing triple-use valve 10, piston 8 end face of centralizing cylinder two is exerted pressure, and middle cylinder 23 is resetted, along with the continuous injection of hydraulic oil, piston 8 end face of centralizing cylinder two is exerted pressure, until middle cylinder 23 resets completely.
In sum, the present invention has set up prop drawing triple-use valve 10 and prop drawing passage 9, during fluid injection, by the fluid injection of liquid injecting mouth 14 pairs of setting prop passages 6, simultaneously by discharge mechanism 15 pairs of prop drawing path 10 unloadings, during prop drawing, liquid injecting mouth 14 is by carrying out fluid injection in prop drawing triple-use valve 10 pairs of prop drawing passages 9, discharge mechanism 15 pairs of setting prop triple-use valves 5 unload end enters middle cylinder 23 piston end surface to the hydraulic oil in setting prop passage 6 simultaneously, middle cylinder 23 is resetted, along with hydraulic oil ceaselessly enters, the pressure of hydraulic oil can make middle cylinder 23 reset completely, efficiently solve because prop drawing not exclusively causes the problem that difficult and middle cylinder surfaces are easily damaged, ensure the application life of hydraulic prop.
Another advantage of long-range liquid injection system is used to be, when needing the work plane prop drawing to danger, workman only need be arranged on the fluid injection end of prop drawing triple-use valve 10 and the unloading end of setting prop triple-use valve 5 liquid injecting mouth 14 and discharge mechanism 15 respectively, long-rangely can make leg restoration, determine whether again to need withdrawing prop according to field condition, thus effectively can avoid the generation of the personnel casualty accidents caused because of prop drawing.
