Abstract
The invention discloses a pull type rope drive device. In an automatic national flag raising and national anthem playing system, the problem of the rope drive technology can not be solved easily, and the practical demand can not be met due to the fact that the factors such as skidding exist when a rope is driven by friction force. An existing rope take-up working mode such as pull type rope drive (like a windlass and a winch) can meet the demand in nature, however, additional power is needed in the rope pay-off process. According to the pull type rope drive device, pay-off and take-up of the rope are achieved by a drive wheel without other power. The drive wheel 3 of the device is provided with a wheel groove 4a and a wheel groove 4b, the two ends of the drive rope 1 and 2 (one rope) are fixed at the fixing point 6 and the fixing point 7 in the wheel groove 4a and the wheel groove 4b respectively, and the winding directions of the drive rope 1 and 2 in the wheel groove 4a and the wheel groove 4b are opposite. The pull type rope drive device is suitable for drive application of the rope with a limited length, and is specially designed for the automatic national flag raising and national anthem playing system in practical.
Description
Technical field
The present invention relates to a kind of pulling type rope driving device, especially the pulling type rope driving device that forms of two races of drive wheel and a transmission rope.
Background technique
Automatically raise national flag and play the national anthem, comprise actual product and the design of the toy product reduced, technically only have the drive method by the frictional force between drive wheel and transmission rope at present in rope drive.Because frictionally transmission rope does not reach more lasting precision, so never ripe product, comprise toy product.Separately have a kind of rope driving device by pulling force, as winch, winch etc., one end of transmission rope is fixed on wheel, pulls transmission rope to be wound on the upper operation of wheel, but be by other power when putting rope during rope closing by immovable point.
Summary of the invention
The object of this invention is to provide a kind of pulling type, and rope driving device that retractable rope is completed by a drive wheel.More lasting precision can be reached, fundamentally solve this technical barrier.
For achieving the above object, drive wheel of the present invention is taken to the belt pulley of rare two races, two race sizes identical (can with two identical belt pulley compositions).Article one, two end points of transmission rope are separately fixed at the fixed point (can bore an aperture, transmission rope is through going to hitch) in two races.The coiling direction of transmission rope in two races is contrary, when drive wheel rotates, two races rope closing another put rope, rope closing is identical with the length of putting rope.Drive wheel is rotated by the end points of immovable point with transmission rope when rotating, and rope closing groove hauls transmission rope by immovable point and runs.When drive wheel opposite direction rotates, another race becomes rope closing groove.Transmission rope can around multi-turn in race, but often enclose length should be substantially identical.
Compared with prior art, the present invention is not the frictional force between roller cell wall and transmission rope, but haul transmission rope operation by drive wheel by the immovable point of rope closing groove, so fundamentally solve the problems such as friction slip, making rope drive technology realize more lasting precision becomes possibility.In addition, compared with existing pulling type rope drive technology, the drive wheel that present invention employs two races realizes retractable rope, and does not need other power.The present invention is applicable to the situation that finite length is run, as automatic ascending, descending flag.
Accompanying drawing explanation
In accompanying drawing 13 is drive wheels, and dotted line 4 is schematic diagram of race, and 5 is axis holes, and 1,2 is transmission ropes.
Accompanying drawing 2 is left side views of accompanying drawing 1, and wherein 1,2,3 is consistent with 1 in accompanying drawing 1,2,3.Article two, the immovable point 6,7 in race 4a, 4b is fixed wtih two end points (relative position of two immovable points does not require) of transmission rope respectively.As seen from the figure, in two races, the coiling direction of transmission rope is contrary.
Embodiment
Accompanying drawing 3 is that the present invention is in a kind of embodiment in the system of playing the national anthem of automatically raising national flag.Wherein 1,2,3,4,5 is consistent with 1 in accompanying drawing 1,2,3,4,5.Transmission rope 1,2 is parallel upwards (if upwards can will use a pair pulley perpendicular to drive wheel plane) again after pulley 11,12 break-in, dotted line 9 is parts that transmission rope hangs over 8 li, the pulley at flagpole (not shown) top, and 1,2,9 is transmission ropes.National flag 10 rises along with the operation of transmission rope or declines.Drive wheel 3 available step motor drives (available decelerating step motor), for hoisting a flag when rotating counterclockwise, for lowering flag when rotating clockwise.
The electronic section of the system of playing the national anthem of automatically raising national flag is that prior art easily realizes, but rope drive technology does not reach practical requirement always, the present invention fundamentally solves this technical barrier, and the product developed thus market needs for a long time and never has.Can first do the toy product reduced, the market demand will be very large.
