Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is a kind of embodiment circuit diagram of the utility model;
Fig. 2 is the another kind of embodiment circuit diagram of the utility model.
The specific embodiment
As shown in Figure 1, the control setup of volitional check aerial platform operation order has a power supply E, proportion magnetic valve YJ, potential device handle SB and potential device handle detector switch S; The end of potential device handle SB is connected with positive source, and two ends are parallel with proportion magnetic valve YJ in addition; Be connected in parallel on the two ends of power supply E after its corresponding solenoid directional control valve series connection of all functional switches.Getting on the bus respectively connects a diode on all functional switches, is used to control the relay I J1 of diode logic; It is parallelly connected after potential device handle detector switch S connects with the coil of relay II J2 with power supply E; Diode is connected with the coil of relay I J1 through the open contact of relay I J1, is parallel with the normally closed contact of relay II J2 at the two ends of this open contact; Potential device handle SB is connected with proportion magnetic valve YJ through another open contact of relay I J1.
As shown in Figure 2, the control setup of volitional check aerial platform operation order has a power supply E, proportion magnetic valve YJ, potential device handle SB and potential device handle detector switch S; The end of potential device handle SB is connected with power supply E is anodal, and two ends are parallel with proportion magnetic valve YJ in addition; Be connected in parallel on the two ends of power supply E after its corresponding solenoid directional control valve series connection of all functional switches.At the functional switch place of getting on the bus a motion detection switch, the intermittence≤10mm between motion detection switch and functional switch are installed near each; One end of motion detection switch is connected with positive source, and the other end is connected with relay I J1, and relay I J1 is connected with power cathode; It is parallelly connected after potential device handle detector switch S connects with the coil of relay II J2 with power supply E; The open contact of relay I J1 is connected on the circuit between motion detection switch and the relay I J1, is parallel with the normally closed contact of relay II J2 in the both sides of this open contact; Another open contact of relay I J1 is connected on the circuit between potential device handle SB and the proportion magnetic valve YJ.
Working process with mode one is an example: when staff's operation was got on the bus, power supply E sent electricity, if sequence of operation is correct; The functional switch of promptly operating earlier, then functional switch and relay I J1 constitute loop, the charged and self-sustaining of relay I J1; This moment potential device handle SB and proportion magnetic valve YJ bonded assembly circuit turn-on; If operate potential device handle SB again, then potential device handle SB is effective to the resistance signal of proportion magnetic valve YJ output, and operational motion is effective.
If the sequence of operation mistake, promptly that operation earlier is potential device handle SB, and the potential device handle detector switch S and power supply E, the relay II J2 that then are used to detect this handle action constitute the loop, make relay II J2 charged; Because relay II J2 is charged, the normally closed contact of relay II J2 breaks off, and then cuts off the loop of functional switch and diode, relay I J1 formation; If this moment is further operating function switch, because the loop is cut off, relay I J1 can't charged again work, so the loop of potential device handle SB and proportion magnetic valve YJ formation also can't conducting, so operational motion is invalid.
The working process of mode two is the same with said process.
