The specific embodiment
Embodiment mono-:
The present embodiment is a kind of hydraulic efficiency gear of rapid automobile quantifying and loading station, its structure is as Fig. 1, shown in 2, comprise: the surge bunker gate oil cylinder 5 of mounted in pairs on four ingredients mouths of surge bunker 3, be arranged on two quantitative storehouse discharge gate oil cylinders 1 on 6 discharge gates of quantitative storehouse, be arranged on two chute telescopic oil cylinders 10 on chute 2, be arranged on the chute rotary actuator 9 on chute suspension bracket, two counterweights that are arranged on quantitative storehouse are demarcated oil cylinder 7, described surge bunker gate oil cylinder is connected with the remote valve station 4 being arranged on surge bunker steelframe by pipeline, described remote valve station by pipeline be arranged on quantitative storehouse steelframe on be connected with the main pumping station 8 of hydraulic reservoir, described main pumping station is by pipeline and described quantitative storehouse discharge gate oil cylinder, chute telescopic oil cylinder, demarcate counterweight oil cylinder, chute rotary actuator connects, described remote valve station is provided with three energy storages 401 in parallel with described surge bunker gate oil cylinder, and described main pumping station is provided with two fix-displacement pump 802, and two described fix-displacement pump exits are respectively equipped with unloader valve, described main pumping station is provided with an energy storage 801 in parallel with described quantitative storehouse discharge gate oil cylinder, chute telescopic oil cylinder, demarcation counterweight oil cylinder, chute rotary actuator.
The surge bunker volume of loading station is huge, in order to improve batching speed, multiple ingredients mouths is set on surge bunker conventionally, and each ingredients mouth arranges two fan bulkhgead gates conventionally, and every fan brake Men Youyi oil cylinder drives.Surge bunker described in the present embodiment has adopted four gates, therefore, needs the oil cylinder 5.1-5.8 of 8 mounted in pairs.These 8 oil cylinders are controlled by the remote valve station being arranged separately on surge bunker steelframe.
On described remote valve station, the fix-displacement pump of independent supply line normal pressure is not set, but is provided with three energy storages 401.1,401.2,401.3.Overpressure moment while utilizing the stored energy supplement gate oil cylinder of energy storage to start declines, meanwhile, and the impact that the overpressure moment producing while utilizing energy storage to absorb gate oil cylinder stop motion increases.Because surge bunker gate is that eight oil cylinders start in the time opening simultaneously, and stop moving simultaneously, its startup and the moment impact stopping are larger, press impact to propagate too far in order not make intraluminal fluid, the present embodiment is provided with three energy storages eight nearest distances of surge bunker gate oil cylinder pipeline, on the remote valve station arranging on the nearest surge bunker steelframe of surge bunker gate oil cylinder, sets up three energy storages.
Quantitatively storehouse discharge gate oil cylinder (1.1 and 1.2), chute telescopic oil cylinder (10.1 and 10.2), demarcation counterweight oil cylinder (7.1 and 7.2) are two.Due to, the situation that quantitatively storehouse discharge gate oil cylinder, chute telescopic oil cylinder, demarcation counterweight oil cylinder, chute rotary actuator do not start simultaneously and stop, open and mostly be two oil cylinders most simultaneously, the intraluminal fluid producing presses impact relatively little, therefore, on the main pumping station of these hydraulic actuating cylinders and hydraulic motor lines close together, only set up an energy storage.
Should be noted that energy storage is matured product, its internal capacity of the energy storage of different size specifications is certain, and its buckles bearing is also certain.Therefore, for bearing different hydraulic efficiency impact amounts, can select the energy storage of different size, and the energy storage of same specification varying number.The present embodiment arranges three energy storages on remote valve station, and an energy storage is set on main pumping station, has expressed the accumulation of energy ratio of energy storage at remote valve station and base pump station with this.

Two unloader valves 803.1,803.2 that are arranged on two fix-displacement pump exits, can discharge the greater impact in pipeline.These hydraulic efficiency impacts are because the pressure instantaneous variation that each power element that hydraulic tubing connects causes while starting or stoping causes.The power of power element is larger, or the power element simultaneously opening and closing is more, and the hydraulic pressure of pipe line of generation impacts larger.The present embodiment, except using energy storage to absorb part impact, has also used unloader valve to discharge the energy impacting.
Moment while unlatching for dynamic factors the pressure decreased in hydraulic tubing, traditional method is the power that increases propulsion source, the power that is about to the Hydraulic Pump that line pressure is provided is brought up to the level that is enough to resist instantaneous loss of pressure.The problem of doing is like this that the power of pump improves too much, and the bearing capacity of pipeline will be improved largely simultaneously.Using energy storage can significantly reduce the power of Hydraulic Pump, can be also that the bearing capacity of pipeline reduces, and single this manufacturing cost of saving is just considerable.
Therefore, the design of fix-displacement pump+energy storage+unloader valve that the device described in the present embodiment adopts, can effectively reduce driving power, and meet the pressure oil requirement of instantaneous large flow.
Because automobile loading station is the mechanical device of working in the wild, its hydraulic efficiency pressure system will experience the environment of severe cold and heat, and the viscosity of hydraulic oil changes along with the change of temperature.For improving the hydraulic working oil environment installing described in the present embodiment, the present embodiment is provided with temperature monitor 808 on hydraulic reservoir, and is provided with hydraulic oil heating unit and hydraulic oil cooling unit 806.Under the control of temperature controller, the temperature of hydraulic oil in fuel tank is monitored, once too high or too low for temperature, start heating or cooling unit, make hydraulic oil remain on the level of the work of being suitable for.And be provided with liquid level monitoring unit 804, the hydraulic pressure oil mass in fuel tank is monitored.On hydraulic reservoir, be also provided with hydraulic oil oil-returning filtering device 805.
The communication port that the present embodiment can also be imported and exported at oil cylinder, appropriate location in pipeline arranges pressure sensor, with the pressure sensor of Bonding pressure transmitter and so on.Use in the whole device of detection that these sensors can be real-time the pressure of hydraulic oil everywhere, and judge the service condition of whole device by analysis, occur extremely, process at once, prevent trouble before it happens, reduce accident rate.
