Abstract
A dual-speed lifter driven by steel cable for building construction is composed of machine frame, steel cable, draw wheel, draw machine, transition wheel and cage. The both ends of steel cable are fixed to machine frame. Said steel cable passes through draw wheel and transition wheel in winding mode and is stretched by them. When the draw wheel is driven by draw machine, its rotation can make the cage move up and down under the action of friction. Said draw wheel has two cable races with different diameters, so giving out two speeds of cage. Its advantages are simple structure, smooth running and high safety and reliability.
Description
The present invention relates to a kind of steel cable dual construction lifter driven, existing elevator mainly contains two kinds, and a kind of is the rack-and-gear driving type, and another kind is the Elevator with the steel rope transmission.Preceding its complex structure of a kind of elevator, manufacturing cost height, installation and maintenance difficulty.A kind of elevator in back must be joined the balance iron of certain mass, slide relative between steel rope and the traction sheave is obvious, even the free sliding phenomenon fast of appearance, cage is when moving or stopping (starting), elasticity jumping phenomena about having significantly, and the steel rope consumption is many, changes difficulty, service life is short, and these two kinds of elevators all have only a kind of hoisting speed.
The objective of the invention is to overcome the deficiency of existing elevator, and a kind of later-model elevator--dual construction lifter driven by steel cable is provided.This elevator adopts the power carrying means of many platform independent, and cage operates steadily, and is safe and reliable, has two kinds of hoisting speeies arbitraryly to select, and simple in structure, low cost of manufacture, and installation and maintenance are convenient.
The present invention is achieved in that spaced winding in the steel rope is enclosed within on traction sheave and the transition wheel, and steel rope two ends are fixed and tensioning, when traction sheave rotates, under the effect of friction, move up and down and drive cage, two groovings that diameter is different are arranged on the traction sheave, and therefore, cage has two kinds of corresponding up-and-down movement speed.
In conjunction with Fig. 1 dual construction lifter driven by steel cable is further described: elevator is made up of frame (1), steel rope (2), traction sheave (3), towing machine (4), transition wheel (6) and cage (6).One end of steel rope (2) is fixed on the top of frame (1), middle earlier in the grooving that is enclosed within transition wheel (6), return up then in one of them grooving that is enclosed within traction sheave (3), return the bottom of getting off to be fixed in frame (1) again, and steel rope (2) is tensioned to a kind of degree, the tensile force summation is during greater than (cage total mass+lifting object total mass) ÷ e μ α, when towing machine (4) drive traction sheave (3) is done positive and negative rotation, under the effect of the friction between steel rope (2) and the traction sheave (3), traction sheave (3) is along steel rope (2) scroll-up/down, and forces cage (6) to move up and down.Traction sheave (3) is installed on the towing machine (4), and towing machine (4) is installed in the top of cage (6), and transition wheel (5) is installed in the bottom, side of cage (6).Two groovings that diameter is different are arranged on the traction sheave (3), and when steel rope (2) was in being enclosed within the big grooving of diameter, cage (6) was made rapid movement, otherwise, then make microinching.Because steel rope (2) is in tensioning and static { with respect to frame (1) or ground } state all the time, elasticity takes place beat and be free to slide phenomenon so cage (6) moves and stops Shi Buhui, and the steel rope consumption is few, long service life, it is easy to change.Form by steel rope (2), traction sheave (3), towing machine (4), transition wheel (5) and to overlap independently power carrying means, the present invention goes up to install at a cage (6) and overlaps independently power carrying means more, therefore, cage (6) operation is very steady, safe and reliable.
Claims (3)
1, dual construction lifter driven by steel cable is made up of frame (1), steel rope (2), traction sheave (3), towing machine (4), transition wheel (5) and cage (6).Be primarily characterized in that the two ends of steel rope (2) are separately fixed at the top and the bottom of frame (1), middle spaced winding is enclosed within the grooving of traction sheave (3) and transition wheel (5), and steel rope (2) is in tensioning all the time, and { the tensile force summation is greater than (cage quality summation+lifting object quality summation) ÷ e
μ αWith static { with respect to frame (1) or ground } state.
2, according to the dual construction lifter driven by steel cable of claim 1, it is characterized in that two groovings that diameter is different are arranged on the traction sheave (3), traction sheave (3) had both been done self and had been rotated, and made scroll-up/down along steel rope (2) again.
3,, it is characterized in that many towing machines (4) are installed at the top of cage (6) according to the dual construction lifter driven by steel cable of claim 1.
