Abstract

The utility model provides a staircase with vertically height-adjustable stair boards. The underside of each stair is connected with a pneumatic/hydraulic piston; a pneumatic/hydraulic cylinder is arranged on a staircase main frame; gas/liquid guide tubes at two ends of the pneumatic/hydraulic cylinder are connected with a gas/liquid power tank through an electromagnetic gas/liquid valve; the electromagnetic gas/liquid valve is connected with an appliance control part; two sides of each stair surface of the staircase are respectively provided with a vertical downward guide pillar; guide rails matched with the guide pillars under the stairs are respectively arranged on sloping plates on two sides of the staircase main frame; a control switch is arranged on a handrail of the staircase. The staircase with vertically height-adjustable stair boards is simple in structure, relatively smaller in occupied volume and area, low in construction cost and capable of applying to common buildings. Every stair board can vertically move up and down within a distance range of three stair heights; passengers push the control switch to elevate stair surfaces of the staircase, so as to achieve the aim that two stair surfaces are in the same plane, and the passengers can be elevated only by moving in the plane.

Description

The liftable stair of stair tread

Technical field

The utility model belongs to the stair of building building, the liftable stair of particularly a kind of stair tread.

Background technology

Highrise building has elevator at present, elevator cost height, and power consumption is big.Escalator is arranged again, and its volume is big, and floor space is big, the equipment complexity, and the cost height can only be used for heavy constructions such as shop, restaurant, station, and general residence building can not be suitable for.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of stair tread liftable stair.Can be used for general residence building.

The technical solution of the utility model is:

The liftable stair of a kind of stair tread, it is characterized in that: each ladder of stair is an independently controlled automatic lifting unit, the following connection gas/liquid that is each ladder is pressed piston, on the stair main body frame, pneumatic/hydraulic cylinder is arranged, pneumatic/hydraulic cylinder has the gas/liquid conduit to connect gas/liquid power jar, electromagnetism gas/liquid valve connecting circuit control section through electromagnetism gas/liquid valve; On the handrail of stair, gauge tap is arranged.

Respectively there is vertical downward guide pillar both sides below each ladder, have on the swash plate of the both sides of stair main body frame the guide rail that cooperates with guide pillar below every ladder is respectively arranged.

Electrical control part has the computer single-chip microcomputer, and the input of computer single-chip microcomputer connects gauge tap, and gauge tap connects encoder; The output of computer single-chip microcomputer connects the promotion circuit module, promotes circuit module and connects electromagnetism gas/liquid valve through relay.

The utility model effect is:

The liftable staircase structure of this stair tread is simple, and it is little relatively to take the volume area, goes for common building.Cost is low, and stair also can use during power failure, fire safety.Can vertically move up and down in three ladder height distance ranges by every rank stair tread, press gauge tap lifting stair terrace by the passenger-in-elevator, reach two-layer terrace on a plane, the passenger-in-elevator only moves on the plane can reach the lifting purpose.

The specific embodiment

The liftable stair schematic diagram of a kind of stair tread as shown in Figure 1, each ladder of stair is an independently controlled automatic lifting unit, the following connection gas/liquid that is each ladder 1 is pressed piston 2, and pneumatic/hydraulic cylinder 3 is arranged on the stair main body frame, and pneumatic/hydraulic cylinder has gas/liquid conduit 4.

Respectively there is vertical downward guide pillar 5 both sides below each ladder, have on the swash plate of the both sides of stair main body frame the guide rail 6 that cooperates with guide pillar below every ladder is respectively arranged.

As shown in Figure 2: the gas/liquid pressure-controlled syndeton that is one deck ladder: pneumatic/hydraulic cylinder 3 connects threeway electromagnetism gas/liquid valve 7 through gas/liquid conduit 4, it is high pressure compressed gas/liquid jar 8 that threeway electromagnetism gas/liquid valve one end connects gas/liquid power jar, high pressure compressed gas/liquid jar connects compressor 9 outputs, the compressor input connects low pressure gas/flow container 10, and low pressure gas/flow container connects the threeway electromagnetism gas/liquid valve other end.The Electromagnetic Control part connecting circuit control section 11 of threeway electromagnetism gas/liquid valve; The gauge tap 12 that electrical control part is arranged on the handrail of stair.Every layer like this all has a same cover.

Shown in Figure 3 is one deck ladder electrical control part: the computer single-chip microcomputer is arranged, and the input of computer single-chip microcomputer connects gauge tap, and gauge tap connects encoder; The output of computer single-chip microcomputer connects the promotion circuit module, promotes circuit module and connects relay, and relay connects electromagnetism gas/liquid valve.Every layer like this has.

Every rank stair tread can vertically move up and down in three ladder height distance ranges, presses gauge tap lifting stair terrace by the passenger-in-elevator, reaches two-layer terrace on a plane, and the passenger-in-elevator only moves on the plane can reach the lifting purpose.
