Detailed description of the invention
Now claimed to the utility model with detailed description of the invention by reference to the accompanying drawings technical scheme is described in further detail.
As shown in Figure 1, the energy-saving safeguard device in the present embodiment comprises lifting pole 1, tooth bar 2, gearbox 3, hydraulic pump 4, two pressure energy energy storage equipments 5, monitoring unit 6, pressure-regulating valve 7, fuel tanks 8.Its middle rack 2 is connected with lifting pole 1, is connected by tooth bar 2 pairs of lifting poles 1.The power shaft of gearbox 3 is provided with travelling gear, and driving cog wheel and rack 2 engagement makes tooth bar 2 moving belt driven input shaft rotate, and power shaft also can be with carry-over bar 2 to move when rotated conversely.Can extract hydraulic oil by primer fluid press pump 4 when the output shaft of gearbox 3 is connected with hydraulic pump 4 is made output shaft rotation by shaft coupling, when hydraulic oil flows backwards through hydraulic pump 4, hydraulic pump 4 can drive output shaft to rotate conversely.When external force inputs from the power shaft of gearbox 3, output shaft can export external force with the rotating speed of less moment of torsion and Geng Gao, and when external force inputs from the output shaft of gearbox 3, power shaft can export external force with larger moment of torsion and lower rotating speed; Hydraulic pump 4 moment of torsion of needing when extracting hydraulic oil is lower little comparatively speaking, and lifting pole 1 then needs larger moment of torsion when being elevated, and utilizes gearbox 3 transmission between hydraulic pump 4 and lifting pole 1 can reduce the configuration of lift platform power demand.
Hydraulic pump 4 also carries out circulation with two pressure energy energy storage equipments 5, monitoring unit 6, pressure-regulating valve 7, fuel tank 8 successively and is connected, wherein two pressure energy energy storage equipments 5 to be connected in parallel on from hydraulic pump 4 to pressure-regulating valve 7 oil pipeline 9.Pressure-regulating valve 7 is in closed condition time flat, monitoring unit 6 is responsible for the pressure in monitoring oil pipeline 9, can open pressure-regulating valve 7 make hydraulic oil flow into fuel tank 8 through pressure-regulating valve 7 to reduce pressure in oil pipeline 9 when monitoring unit 6 after pressure is greater than the setting value of monitoring unit 6.
As shown in Figure 2, each pressure energy energy storage equipment 5 device includes proportional throttle valve 51, store fluid cylinder 53, gas compression bag 54, pressure sensor 55, electromagnetic valve 52.Wherein to be connected in parallel mutually between proportional throttle valve 51 with electromagnetic valve 52 and the two ends of proportional throttle valve 51 and electromagnetic valve 52 are connected oil pipeline 9 respectively and store fluid cylinder 53, to be also connected with gas compression bag 54 and pressure sensor 55 storing on fluid cylinder 53.Negative pressure is produced in order to avoid storing fluid cylinder 53 inside, store fluid cylinder 53 inside and have gas except storage has hydraulic oil also to store, when hydraulic oil input stores in fluid cylinder 53, the gas of its inside can be extruded in gas compression bag 54 by this portion gas of gas compression bag 54 temporary storage by hydraulic oil, pressure sensor 55 is responsible for monitoring the pressure in gas compression bag 54 and control ratio choke valve 51 and electromagnetic valve 52, pressure sensor 55 has the setting value of two pressure to be respectively high pressure set point and low-pressure settings, proportional throttle valve 51 can be closed when the pressure in gas compression bag 54 rises to pressure sensor 55 after high pressure set point, when pressure sensor 55 after the near low-pressure settings of the pressure in gas compression bag 54 can shut electromagnetic valve 52.
The present embodiment is when ocean platform declines, lifting pole 1 can drive hydraulic pump 4 to extract hydraulic oil from fuel tank 8 through the transmission of tooth bar 2, gearbox 3 successively, proportional throttle valve 51 now on two pressure energy energy storage equipments 5 is opened electromagnetic valve 52 and is closed, hydraulic oil flows into through proportional throttle valve 51 and stores in fluid cylinder 53, the gas stored in fluid cylinder 53 is pressed against in gas compression bag 54 and the pressure in gas compression bag 54 is raised, and pressure energy is stored in pressure energy energy storage equipment 5 with the form of gases at high pressure and high pressure liquid force feed.Will close proportional throttle valve 51 when pressure sensor 55 monitors the hypertonia in gas compression bag 54 make hydraulic oil stop inflow storing in fluid cylinder 53, if now hydraulic pump 4 stops oil transportation not yet, pressure in oil pipeline 9 can continue to raise, and can open pressure-regulating valve 7 make hydraulic oil flow in fuel tank 8 through pressure-regulating valve 7 pressure reduced in oil pipeline 9 when monitoring unit 6 after pressure is increased to the setting value of monitoring unit 6.Pressure rising in oil pipeline 9 can affect the speed that hydraulic pump 4 extracts hydraulic oil conversely, its resistance finally can reduce the decrease speed of ocean platform through transmission, when ocean platform energy-saving safeguard device when the brake that declines is out of control can play certain decelerating effect auxiliary brake.
The present embodiment is when ocean platform rises, choke valve shut electromagnetic valve 52 on one of them pressure energy energy storage equipment 5 is opened, the high pressure liquid force feed stored in fluid cylinder 53 flows in oil pipeline 9 through electromagnetic valve 52, gases at high pressure in gas compression bag 54 also can get back to the pressure drop storing in fluid cylinder 53 and make in gas compression bag 54, when pressure sensor 55 after pressure drop to the low-pressure settings of pressure sensor 55 can make hydraulic oil stop flowing out from storing fluid cylinder 53 by shut electromagnetic valve 52; Subsequently, choke valve shut electromagnetic valve 52 on another pressure energy energy storage equipment 5 is opened, the high pressure liquid force feed stored in fluid cylinder 53 flows in oil pipeline 9 through electromagnetic valve 52, gases at high pressure in gas compression bag 54 also can get back to the pressure drop storing in fluid cylinder 53 and make in gas compression bag 54, when pressure sensor 55 after pressure drop to the low-pressure settings of pressure sensor 55 can make hydraulic oil stop flowing out from storing fluid cylinder 53 by shut electromagnetic valve 52.Because pressure-regulating valve 7 is in closed condition, can be back in fuel tank 8 through hydraulic pump 4 by the hydraulic oil of release in two pressure energy energy storage equipments 5, hydraulic oil can make its rotor reverse when through hydraulic pump 4, its active force is moving lifting pole 1 lifting ocean platform through gearbox 3, tooth bar 2 transmission rear-drive successively, makes pressure energy evenly discharge at the uniform velocity lifting ocean platform because two pressure energy energy storage equipments 5 discharge its pressure energy one by one.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
