Abstract
An escalator uniform speed variator is provided, which is mounted at the prefix and suffix of an escalator to accelerate or decelerate the escalator at a certain acceleration velocity. The escalator speed variator comprises a row of parallel-equipped transmission steel columns arranged at the tail end of an escalator and on the ground, and a gear sleeved around at one end of each transmission steel column. Two adjacent gears are connected with a speed-changing gear with a specified tooth proportion, so that each transmission steel column is rotated based on the acceleration formula: Vt<2>=2as. The whole device forms a speed uniformly changing system and connected with the escalator by a crawler track. The people standing on the escalator make a uniform speed-variable linear motion at an acceleration velocity (a) and can steadily get in and off the escalator. The utility model can increase the velocity of the escalator without dangerous risk.
Description
Affiliated technical field
The utility model relates to the safe additional device of a kind of non-lifting mode elevator prefix and suffix, especially can be with certain acceleration the even change-speed box of the elevator of acceleration of the people on the elevator or deceleration.
Background technology
At present, known non-lifting mode elevator and floor bonded assembly are constructed and are, a block plate is erected on the end and floor of elevator, and does not contact with elevator, and its both sides and that side on the floor are held by the floor, and elevator just skids off under steel plate and slips into.People will take a lift, and go to earlier on the steel plate, directly step into elevator from steel plate again; When going out elevator, just walk out after also must stepping up steel plate.But, steel plate is static, elevator travels at the uniform speed, when the people steps into elevator or when elevator was stepped up steel plate, the people will be by static unexpected motion or static suddenly by motion, because inertia from steel plate, people will be fallen down unless you give your whole attention to it, and the speed of elevator is big more with regard to easy more being fallen down, and has just limited the speed of elevator thus to a great extent for safety, brings a lot of inconvenience to people.
Summary of the invention
In order to overcome the deficiency that fall down the people easily and therefore dare not raise speed at existing non-lifting mode elevator doorway place, the utility model provides a kind of even change-speed box of elevator that is installed in elevator prefix and suffix, should can not only the people gently be quickened or slow down by even change-speed box, make the people be difficult for being fallen down, and can when improving elevator speed, not constitute danger.
The technical scheme that its technical matters that solves the utility model adopts is: on the end and floor of elevator, set up the transmission round steel posts that be arranged in parallel greatly such as a row, and transmission round steel post solid matter and level, every transmission circle guiding principle post one end all overlaps and cogs.Adjacent two gears are all connected by specific number of teeth ratiometric variable gear, make all transmission round steel posts be linked to be a system, as long as wherein rotation just drive all and together rotate, and each transmission round steel post can only be rotated with specific ratio.They are the velocity contrast between elevator and the floor, be divided into some " trifle speed " that change step by step, these " trifle speed " are successively set on the transmission round steel post, and the gradation law that each specific number of teeth ratiometric variable gear limits transmission round steel post rotating speed meets Acceleration Formula V
2 t=2as (V
tBe the linear velocity of each transmission round steel post, s is the distance of each transmission round steel post to the floor, and a is the acceleration/accel of total system), make it to constitute an even speed change system.Whole device is fixed by steelframe and is held up by the floor.The people sets foot on the even change-speed box of elevator, transmission round steel post contacts with people's sole, rotation along with transmission round steel post, sole is sent toward next transmission round steel post under the effect of friction force in order, it contacts with that part of transmission round steel post, just sliding with that part of speed, that is to say that the people stands in above it, is to do the even change speed linear motion that acceleration/accel is a.Owing to be even change speed linear motion, the people stands in and need only adjust a lower part of the body position above it slightly and just can stop reposefully, is slowly sent to elevator then, sends elevator again.
The beneficial effects of the utility model are, it can gently quicken the people or slow down with certain acceleration, makes people be difficult for being fallen down, and can also improve the running velocity of elevator greatly and do not constitute danger.
