The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further.
As Fig. 1, Fig. 2, shown in Figure 3, the indoor lifting stair of indoor layout of duplex apartment, comprise the guide rail 4 that is provided with on the indoor wall, can be along the control mechanism in guide rail 4 reciprocating box-structure sedan-chair storehouses 1 and sedan-chair storehouse 1, be provided with the hydraulic ram 1.7 of vertical placement in the sedan-chair storehouse 1, the rod end of the hydraulic pressure piston push rod 3 of hydraulic ram 1.7 stretches out sedan-chair storehouse 1 bottom support in ground.Control mechanism comprises fluid control partial sum circuit control part.
As shown in Figure 4, fluid control partly comprises a control cock 1.1 that four ports are arranged, the port A of control cock 1.1 goes up and connects compression indicator 1.6, hydraulic ram 1.7 and pressure switch 1.11, port B is connected fuel tank 1.10 through check valve 1.5, hydraulic hand-pump 1.8 and oil filter 1.3, also be provided with the two shutoff valve 1.9 of direct connection between port B and the fuel tank 1.10, port C is connected fuel tank 1.10 through check valve 1.5, electric hydraulic pump 1.2 and oil filter 1.3, also is provided with the pressure regulating valve 1.4 that links to each other with fuel tank 1.10 between check valve 1.5 and the electric hydraulic pump 1.2.
The HYDRAULIC CONTROL SYSTEM principle is as follows:
When the electromagnetic valve that hoists (calling the electromagnetic valve that hoists in the following text) of control cock 1.1 when electric, oil circuit A and C connect, the oil that has pressure in the electric hydraulic pump 1.2 drives the piston push rod of hydraulic ram 1.7, makes indoor companion ladder sedan-chair storehouse (following abbreviation sedan-chair storehouse) rise; Rising puts in place stops (circuit control) automatically, when the landing electromagnetic valve of control cock 1.1 (calling the landing electromagnetic valve in the following text) when electric, oil circuit A and D connection, the piston push rod of hydraulic ram 1.7 lands under the effect of sedan-chair storehouse gravity, oil in the hydraulic ram flows back to fuel tank 1.10, finishes a lifting process.
If have a power failure or the electrification of being unwilling, then can use manpower; Control cock oil circuit A and B when not having electricity connect, but the lever of at this moment back and forth pulling hydraulic hand-pump with hand just the piston push rod of direct drive hydraulic ram 1.7 the sedan-chair storehouse is risen; When needing to fall, the people opens the landing automatically under the effect of sedan-chair storehouse gravity of shutoff valve 1.9 hydraulic ram pistons, and the oil in the hydraulic ram flows back to fuel tank 1.10.
As shown in Figure 2, the circuit control part comprises the control major loop of power supply, be in series with stop button 2.1 on the control major loop of power supply, door interlock switch 2.6 and control branch road, the control branch road comprises the control branch road that hoists of mutual parallel connection, landing control branch road and oil pump control loop, the control branch road that hoists comprises the series connected bit switch 2.2 that rises to, the normally closed interlocking 2.3 of landing relay, rise button 2.4 and rise relay 2.5, landing control branch road comprises the series connected bit switch 2.7 that drops to, rise the normally closed interlocking 2.8 of relay, landing button 2.9 and landing relay 2.10, the oil pump control loop comprises series connected pressure switch 2.11, rise relay normally open interlocking 2.12, landing normally closed interlocking 2.13 of relay and electric hydraulic pump contactless coil 2.14.
The circuit control principle is as follows:
When needs rise the sedan-chair storehouse, press and rise button 2.4, rise relay 2.5 coils this moment; By stop button 2.1; Rise to bit switch 2.2; The normally closed interlocking 2.3 of landing relay; Rise button 2.4; Door interlock switch 2.6 obtains electric signal, rises relay and gives the solenoid valve that hoists, and control cock oil circuit A and C are connected, and is driven on the sedan-chair storehouse by hydraulic part to rise again; The sedan-chair storehouse rises to desired location, rises to bit switch 2.2 and disconnects, and makes and rises the relay coil outage; The electromagnetic valve that hoists outage, electric hydraulic pump quits work, and the sedan-chair storehouse stops to rise, and finishes the rise process.
When land in needs sedan-chair storehouse, press landing button 2.9, relay 2.10 coils that land this moment are by stop button 2.1; Drop to bit switch 2.7; Rise the normally closed interlocking 2.8 of relay; Landing button 2.9; Door interlock switch 2.6 obtains electric signal, and the landing relay is given the landing solenoid valve, and control cock oil circuit A and D are connected; By hydraulic part the sedan-chair storehouse is descended again; The sedan-chair storehouse drops to desired location, drops to bit switch 2.7 and disconnects, and makes the outage of landing relay coil; The landing process is finished in the outage of landing electromagnetic valve.
Electric hydraulic pump only gets electric at the rise relay, the landing relay does not have electricity, works when hydraulic fluid pressure is lower than set-pressure.Electric hydraulic pump quits work when hydraulic fluid pressure is higher than set-pressure.(overvoltage protection).
