The specific embodiment:
Embodiment 1: as shown in Figure 2, the decrease speed regulating system of a kind of hydraulic parking equipment of the present utility model comprises hydraulic cylinder 1, oil pump 4, oil supply pipe 2 and oil returning tube 5, the two ends of oil supply pipe 2 turn on respectively on oil pump 4 and the hydraulic cylinder 1, the two ends of oil returning tube 5 turn on respectively on hydraulic cylinder 1 and the oil pump 4, on the described oil supply pipe 2 oil feed non-return valve 3 is installed, first return check valve 8 and second return check valve 9 are installed on the described oil returning tube 5, on oil returning tube 5, connect the other pipe 7 of oil once in parallel with second return check valve 9, on the other pipe 7 of described oil return an one way valve 10 is installed at least, the other pipe of this oil return 7 is controlled according to the result of detection of load sniffer, the load sniffer is for whether have the device that park cars arbitrarily if can detect vehicle-containing, the load sniffer is a pressure sensor 6 in present embodiment 1, and pressure sensor 6 is installed on the oil returning tube 5 between first return check valve 8 and second return check valve 9.Pressure sensor 6 can select to have the pressure Presentation Function, in order to intuitively reflect the instant pressure of oil return circuit.
Present embodiment 1 is in work, pressure sensor 6 is set rating number according to the pressure condition of vehicle-containing when unloaded and heavily loaded to it, usually the pressure sensor pressure that will be in rating number is exported corresponding to the magnitude of voltage of certain scope or current value and with linear relationship, for ease of control, present embodiment 1 converts thereof into skip signal output.When the vehicle-containing inactive state, first return check valve 8 and second oil return 9 and oil return pipe one way valve 10 all are in closed condition (this state is normality).When vehicle-containing is received the decline instruction, at first open first return check valve 8 near hydraulic cylinder 1, pressure sensor 6 detected the pressure condition of oil returning tube 5 and produced the signal saltus step to represent that vehicle-containing was to be in heavy duty or Light Condition at that time this moment.If heavy condition, then only oil return pipe one way valve 9 is opened in control, because vehicle-containing is heavy duty, though only open an oil return circuit this moment, still can descend with suitable, fast speeds.If Light Condition, then control had both been opened second return check valve 9, had also been opened the one way valve 10 of the other pipe 7 of oil return, was that the two-way oil return circuit is opened at this moment, so unloaded vehicle-containing also can descend rapidly.
Embodiment 2: as shown in Figure 3, the decrease speed regulating system of a kind of hydraulic parking equipment of the present utility model comprises hydraulic cylinder 1, oil pump 4, oil supply pipe 2 and oil returning tube 5, the two ends of oil supply pipe 2 turn on respectively on hydraulic cylinder 1 and the oil pump 4, the two ends of oil returning tube 5 turn on respectively on oil pump 4 and the hydraulic cylinder 1, on the described oil supply pipe 2 oil feed non-return valve 3 is installed, first return check valve 8 and second return check valve 9 are installed on the described oil returning tube 5, on oil returning tube 5, connect the other pipe 7 of oil once in parallel with second return check valve 9, on the other pipe 7 of described oil return an one way valve 10 is installed at least, the other pipe of this oil return 7 is controlled according to the result of detection of load sniffer, the load sniffer is motor vehicle detector 12 in present embodiment 2, described motor vehicle detector 12 is installed in the position, vehicle-containing parking stall of parking apparatus, and whether it can detect on the vehicle-containing and park cars.This motor vehicle detector 12 can be any one or a few in electromagnetic detection, infrared detecting device, ultrasonic detection device and the laser detector.The installation of motor vehicle detector and control mode, one of the preferred position, parking stall that is mounted in all vehicle-containings of parking apparatus, whether the motor vehicle detector of the vehicle-containing correspondence that before vehicle-containing descends needs is descended has the detection of vehicle.Preferred two is that install a position, parking stall that only goes out/go into car layer vehicle-containing at parking apparatus, detects vehicle-containing and whether stop to have vehicle when client's storage/access car, and in the lump store standby with the numbering of corresponding vehicle-containing this information.
When the vehicle-containing inactive state, first return check valve 8 and second return check valve 9 and oil return pipe one way valve 10 all are in closed condition (this state is normality).When vehicle-containing was received the decline instruction, first return check valve 8 was opened, and determines whether park cars on this vehicle-containing with aforementioned manner then.Not having parks cars is zero load; Park cars and be heavy duty.If heavy condition, then only second return check valve 9 is opened back in control, because vehicle-containing is heavy duty, though only open an oil return circuit this moment, still can descend with suitable, fast speeds.If Light Condition, then control had both been opened second return check valve 9, had also been opened the one way valve 10 of the other pipe 7 of oil return, was that the two-way oil return circuit is opened at this moment, so unloaded vehicle-containing also can descend rapidly.
As shown in Fig. 2,3, for slowing down the impact that produces when vehicle-containing drops to ground fast, can a travel switch 11 be installed at the hydraulic cylinder 1 that drives the vehicle-containing motion, the trip switch 11 triggered before vehicle-containing is near ground, close the one way valve 10 of the other pipe 7 of oil return, second return check valve 9 that only keeps on the oil returning tube is opened, and with the speed that the vehicle-containing that slows down descends, reaches the purpose of buffering.
In addition, be the compliance of increase native system, but the one way valve 10 select tape manual adjustments traffic engineering capabilitys on the other pipe of oil return.
In like manner, but second return check valve, the 9 select tape manual adjustments traffic engineering capabilitys on the oil returning tube.
Certainly, also be feasible opening different oil return circuits respectively under Light Condition and the heavy condition.At this moment, for reaching the buffering purpose, two oil return circuits unloaded and heavy duty should be distinguished the other pipe of the oil return of connecting in parallel separately, and trigger control by travel switch 11.
Therefore the above only for embodying the preferred embodiment of the utility model principle, do not limit protection domain of the present utility model, and every equalization of doing according to the utility model changes with modifying and all belongs within the claim that the utility model contains.
