Abstract
The utility model relates to a veil curtain device for well channels of sightseeing elevators. In the utility model, the upper end of an elevator well channel is provided with an upper curtain rolling device (1); the lower end of the elevator well channel is provided with a lower curtain rolling device (17) and a lower drive chain shaft (18); the upper curtain rolling device and a chain wheel (2) are coaxial; the lower curtain rolling device and the chain wheel (16) are coaxial; one of chain wheels on the lower device chain shaft (18) is hinged with the chain wheel (16) by a chain (13); the other chain wheel on the lower device chain shaft (18) is hinged with the chain wheel (2) by a chain (7) of which the both ends are fixed on a hook (8) of an elevator car (21); one end of an upper veil curtain and a lower veil curtain is fixed on the elevator car (21); the other end of the upper veil curtain and the lower veil curtain is fixed on a curtain rolling device. The veil curtain device can cause veil curtains to freely closed and released follow the lifting process of elevators has a fluent and good effect with a moving effect, can prevent pulling force from directly acting on veil curtains, has the advantages of simple structure and high safety, and can be spread and used with large quantity.
Description
Technical field
The utility model belongs to the annex of sightseeing elevator, specifically is a kind of curtain device that is installed on the hoistway.
Background technology
Because sightseeing elevator places the building top layer, equipment mixed and disorderly in the hoistway is exposed outside, not only influence the appearance of the city, sometimes the foreign material in the hoistway are along with the elevator operation trickles down, entail dangers to pedestrian's safety also, block foreign material in the hoistway so people just expect being provided with curtain in hoistway, on curtain, do calligraphy and painting, advertisement simultaneously, environment is beautified; A kind of sightseeing elevator hoistway safety precaution curtain is disclosed in the application case of CN2225460Y, its technical scheme mainly is to cooperate with car by the weight pulling force that is located at the hoistway both sides to finish the folding and unfolding action that drives curtain, because the pulling force of weight directly acts on curtain, if its weight value is improper, curtain gives a discount easily or is fractureed, even the safety misadventure that weight falls takes place.
Summary of the invention
Technical problem to be solved in the utility model is to make the running velocity of the folding and unfolding speed of curtain and elevator synchronous, reach act freely, smooth effect.
The utility model solves the problems of the technologies described above by following technical solution: there is last screen-roller 1 the elevator hoistways upper end, there are following screen-roller 17 and underdrive chain rivet 18 in the lower end, last screen-roller is coaxial with sprocket wheel 2, following screen-roller is coaxial with sprocket wheel 16, one of two sprocket wheels on the underdrive chain rivet 18 are connected with chain 13 chains with sprocket wheel 16, and another sprocket wheel is connected with chain 7 chains with sprocket wheel 2; The two ends of chain 7 are fixed on the hook 8 of car 21; One end of upper and lower curtain is separately fixed on the car, and the other end is separately fixed on the upper and lower screen-roller; The equal diameters of each sprocket wheel.
The utility model by chain sprocket drive make curtain with the elevator lifting process act freely, smooth, dynamic effect is good, avoids drag force to act directly on the curtain, and is and simple in structure, safety performance is good, is worth large-scale popularization to be used.
Description of drawings
Fig. 1 is the main TV structure scheme drawing of the utility model sightseeing elevator hoistway curtain device.
Fig. 2 is the lateral plan of the utility model sightseeing elevator hoistway curtain device.
The specific embodiment
There is the last screen-roller 1 that is contained on the upper winding shaft 4 the elevator hoistways upper end, following screen-roller 17 and the underdrive chain rivet 18 that is contained on the lower winding shaft 14 arranged respectively before and after the lower end, last screen-roller 1 is coaxial with sprocket wheel 2, following screen-roller 17 is coaxial with sprocket wheel 16, two sprocket wheels 19 and 20 are arranged on the underdrive chain rivet 18, be connected by chain 13 between sprocket wheel 19 and the sprocket wheel 16, sprocket wheel 20 is connected by chain 7 with sprocket wheel 2, and the two ends of chain 7 are fixed on the hook 8 of car 21; Upper and lower curtain 6 and an end of 11 are connected the top and the bottom of car 21 respectively with movable hook 9, the other end is respectively on last curtain guide shaft 5 and following curtain guide shaft 12 are fixed on screen-roller and following screen-roller; On hoistway, be fixed with curtain guide groove 10 and sprocket wheel guide groove 22; Described each sprocket diameter equates.
When car down moved, chain 7 drove sprocket wheel 2 and sprocket wheel 20 clickwises, because last screen-roller 1 is connected with sprocket wheel 2 by clutch pawl 3, and also clickwise and emit curtain 6 thereupon; Sprocket wheel 20 drives coaxial sprocket wheel 19 clickwises, and drives sprocket wheels 16 clickwises through chain 13, and following screen-roller 17 is connected with sprocket wheel 16 by clutch pawl 15, and the while, also clickwise and the rolling of finishing down curtain 11 were moved; Otherwise when car up moved, turning to of each sprocket wheel and curtain was opposite with aforementioned direction.Because the equal diameters of each sprocket wheel makes the folding and unfolding speed of curtain consistent with elevator speed.
When needing repairing hoistway equipment or replacing curtain, take off the clutch pawl, screen-roller stops operating, and the operation of elevator is unaffected.If floor is shorter, only need to establish chain wheel driving mechanism in a side of hoistway.
Claims (1)
1, a kind of sightseeing elevator hoistway curtain device, curtain, spool, curtain guide shaft etc. are arranged, it is characterized in that: there is last screen-roller (1) the elevator hoistways upper end, there are following screen-roller (17) and underdrive chain rivet (18) in the lower end, last screen-roller is coaxial with sprocket wheel (2), following screen-roller is coaxial with sprocket wheel (16), one of two sprocket wheels on the underdrive chain rivet (18) are connected with chain (13) chain with sprocket wheel (16), another sprocket wheel is connected with chain (7) chain with sprocket wheel (2), and the two ends of chain (7) are fixed on the hook (8) of car (21); One end of upper and lower curtain is separately fixed on the car, and the other end is separately fixed on the screen-roller; The equal diameters of each sprocket wheel.
