Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
As shown in Figure 1 to Figure 3, a kind of novel pneumatic lift appliance, it comprises car 1, hoistway 2 and some stops 3, described car top 1 is with hoistway 2 inner wall sealing and can slide up and down along hoistway 2 inwall, be provided with in hoistway 2 above car 1 top with the inner wall sealing of hoistway 2 and the interlayer board 4 that can slide up and down along hoistway inwall, the first air extraction space 5 is formed between interlayer board 4 and car 2 top, the second air extraction space 6 is formed between interlayer board 4 and hoistway top, the top of described hoistway 2 is provided with and is fixedly connected with and the first pump-line 7 be communicated with the first air extraction space 5 with interlayer board 4, hoistway 2 top is also provided with the second pump-line 8 be communicated with the second air extraction space 6, described first pump-line 7 is telescopic pump-line or hoseline.The upper end of described first pump-line 7 is connected with the first air pump 11 being installed on hoistway 2 top, lower end is sealedly and fixedly connected by mounting ring 12 and interlayer board 4, when described first pump-line 8 is telescopic pipeline, it is made up of some grades of pipelines, some grades of pipelines are connected by link ends between two, form some grades of pipelines of the first pump-line, its internal diameter reduces from top to bottom successively, and well headroom is provided with the first vacuum valve 9 matched with the first air pump 11.
The inwall of described hoistway 2 is provided with guide rail, and described interlayer board 4 is provided with the guide rail draw-in groove 41 matched with above-mentioned guide rail.
Described second pump-line 8 is connected with the second air pump 13 being installed on well headroom, and hoistway 2 top is provided with the second vacuum valve 10 matched with the second air pump.
Described first air pump 11 power is greater than the second air pump 13 power.
The top of described car 1 and the inwall of hoistway 2 realize being tightly connected by the first packing seal 14, and described interlayer board and hoistway inwall realize being tightly connected by the second packing seal 15, are tightly connected between described guide rail draw-in groove 41 and guide rail.
The up principle of car: when receiving interior choosing or calling upward signal outward together, control system first starts the second air pump 13 and bleeds to the second air extraction space 6, be positioned at negative pressure and upward movement that interlayer board 4 above car 1 top formed because of the second air extraction space 6, and drive the lowest part that the first pump-line 1 moves to interior choosing or calls together in floor corresponding to upward signal outward, after this fix with guide rail and stop the second air pump 13 to work.Now, the first air extraction space 5 needs according to call and increases, and the second air extraction space 6 reduces, and the effective air extraction space of the first air extraction space 5 when to be car 1 up.Then start the first relatively large air pump 11 to bleed to the first air extraction space 5.Due to excellent sealing between car 1 top and guide rail, the negative pressure formed in the first air extraction space 5 drives car 1 upward movement, until rest in up object floor place.
The descending principle of car: when receiving interior choosing or calling downgoing signal outward together, opens the first vacuum valve 9, first air extraction space 5 air inlet, and car 1 relies on self gravitation and upper and lower pressure reduction slowly to drop to object floor.After cage descending one segment distance, the second vacuum valve 10 is opened, the second air extraction space 6 air inlet, and interlayer board 4 declines by self gravitation, until close to closing the second vacuum valve 10 during car 2 top, is finally parked in the top of car 1.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change can expected without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
