Description
Technical field
This utility model relates to the fluid power system of sector gate, specifically a kind of sector gate Closed Hydraulic Driving system.
Background technology
Sector gate is widely used in coal washery, and it is mainly responsible for the effect automatically putting off coal and bits. In actual applications, the opening and closing of sector gate are realized by fluid power system. But practice have shown that, the fluid power system of existing sector gate is limit due to self structure, there are the following problems: when occurring suddenly to have a power failure, hydraulic pump in fluid power system can quit work, the piston rod making the hydraulic jack in fluid power system cannot be retracted, thus causing that sector gate cannot be closed in time, thus causing that coal or bits push down automobile and blocking storehouse cylinder phenomenon after overflowing occurs, and then affecting the safety in production of coal washery. Based on this, it is necessary to invent a kind of brand-new fluid power system, the problem that the fluid power system to solve existing sector gate cannot close sector gate in time when occurring and have a power failure suddenly.
Summary of the invention
The problem that this utility model cannot close sector gate for the fluid power system solving existing sector gate in time when occurring and have a power failure suddenly, it is provided that a kind of sector gate Closed Hydraulic Driving system.
This utility model adopts the following technical scheme that realization: sector gate Closed Hydraulic Driving system, including fuel reserve tank, filter, hydraulic pump, multiple directional control valve, hydraulic jack, hand stop valve; Wherein, the oil-in of filter connects with fuel reserve tank; The oil-in of hydraulic pump connects with the oil-out of filter; The oil-in of multiple directional control valve connects with the oil-out of hydraulic pump; The oil return opening of multiple directional control valve connects with fuel reserve tank; The number of hydraulic jack is two; First actuator port of two hydraulic jack all connects with the first actuator port of multiple directional control valve; Second actuator port of two hydraulic jack all connects with the second actuator port of multiple directional control valve; The oil-in of hand stop valve connects with the second actuator port of two hydraulic jack respectively; The oil-out of hand stop valve connects with fuel reserve tank.
During work, the piston rod of two hydraulic jack is connected with two sector gate respectively.Specific works process is as follows: one, the unlatching of sector gate: first, and multiple directional control valve carries out action so that the oil-in of multiple directional control valve and the second actuator port are connected, and the oil return opening of multiple directional control valve and the first actuator port are connected. Then, hydraulic pump extracts the hydraulic oil in fuel reserve tank, and pass sequentially through the oil-in of multiple directional control valve, the second actuator port of multiple directional control valve, two hydraulic jack the second actuator port hydraulic oil is delivered in the second chamber of two hydraulic jack, hydraulic oil in first chamber of two hydraulic jack passes sequentially through the first actuator port of multiple directional control valve simultaneously, the oil return opening of multiple directional control valve is back in fuel reserve tank, the piston rod of two hydraulic jack thus stretches out, thus driving two sector gate to open. Two, the closedown of sector gate: first, multiple directional control valve carries out action so that the oil-in of multiple directional control valve and the first actuator port are connected, and the oil return opening of multiple directional control valve and the second actuator port are connected. Then, hydraulic pump extracts the hydraulic oil in fuel reserve tank, and pass sequentially through the oil-in of multiple directional control valve, the first actuator port of multiple directional control valve, two hydraulic jack the first actuator port hydraulic oil is delivered in the first chamber of two hydraulic jack, hydraulic oil in second chamber of two hydraulic jack passes sequentially through the second actuator port of multiple directional control valve simultaneously, the oil return opening of multiple directional control valve is back in fuel reserve tank, the piston rod of two hydraulic jack is thus retracted, thus driving two sector gate to close. Three, when occurring suddenly to have a power failure, hydraulic pump and multiple directional control valve all quit work. Now, staff quickly opens hand stop valve, namely hydraulic oil in second chamber of two hydraulic jack be back in fuel reserve tank either directly through hand stop valve, the piston rod of two hydraulic jack is fast retractile under the effect of sector gate self gravitation thus, thus driving two sector gate to close in time.
Based on said process, sector gate Closed Hydraulic Driving system described in the utility model is by adopting brand new, achieve and drive two sector gate to close in time when occurring suddenly and having a power failure, the phenomenon pushing down automobile and blocking storehouse cylinder after thus thoroughly avoiding coal or bits spilling occurs, thus being effectively ensured the safety in production of coal washery.
Further, Pressure gauge, relief valve are also included; Manometric oil-in connects with the oil-out of hydraulic pump; The oil-in of relief valve connects with the oil-out of hydraulic pump; The oil-out of relief valve connects with fuel reserve tank. During work, the oil pressure of the oil-out of hydraulic pump monitored in real time by Pressure gauge. When oil pressure is too high, opens the safety-valve and can carry out pressure release, thereby guarantee that the safe operation of hydraulic pump.
This utility model is rational in infrastructure, it is ingenious to design, and efficiently solves the problem that the fluid power system of existing sector gate cannot close sector gate in time when occurring and have a power failure suddenly, it is adaptable to sector gate.
