Abstract
The invention relates to an automatic retractable sail comprising a reel and a mounting seat. The sail is characterized in that wheels are arranged on the mounting seat and are fixed through bearings and pin shafts; two wheels are connected by using shafts; the wheel mounting position in the boom direction and a wheel mounting position in a balance arm direction are symmetric relative to cross sections of the shafts. Guiding grooves are provided between the shafts. The sail is arranged on the shafts through steel wires. According to the invention, a mobile retraction principle is adopted, such that sail windward area is increased or reduced, such that the wind power of wind upon a tower crane is increased or reduced, and rotation resistance is adjusted.
Description
Art
The present invention relates to a kind of automatic telescopic wind sail device of whip-typed tower crane, belong to universal machine field.
Background technology
The development of current global economy, the height of building constantly promotes, new requirement is there has also been like this concerning tower crane for building, the requirement for height of tower machine and load-carrying ability are also improved constantly, according to the handling characteristics of tower crane, high-rise building generally adopts whip-typed tower crane, because the use of tower crane is highly high, very large on the impact of tower machine at the aerial wind-force of height like this, especially whip-typed tower crane.In order to the safe handling of tower crane, the effect of sail embodies particularly important.Mobile sail can solve following problem: 1, according to the size movement automatically of wind; 2, the revolution air draught always keeping whip-typed tower crane minimum; 3, keep tower crane in a non-operative state, keep tail blowing.
Summary of the invention
In order to adjust the air draught of tower crane, the object of this invention is to provide a kind of effective wind control system, the steering resistance of tower crane is dropped to minimum, alleviating the load of swing type mechanism, use the accurate positioning of tower machine, strengthen the safety of tower machine.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of automatic telescopic sail, comprise reel and mount pad, it is characterized in that, mount pad arranges runner, runner is fixed by bearing and bearing pin, is connected between two runners by axle, and the runner installation site in crane arm direction and the runner installation site in equilibrium arm direction are symmetrical about the cross-sectional plane of axle, arrange guide groove between the axles, sail is arranged on axle by steel rope.
The present invention adopts the principle of mobile folding and unfolding, increases and reduce the wind area of sail, thus the wind-force of increase and decrease wind to tower crane adjusts steering resistance.The variation of the wind area of sail is realized automation by the present invention, by the guiding of steel rope system, makes equilibrium arm sail and crane arm sail realize interlock.
Accompanying drawing explanation
Fig. 1 is telescopic wind sail system schematic diagram.
Fig. 2 is schematic diagram.
Number in the figure: 1, reel 2, steel rope system 3, mount pad 4, runner 5, axle 6, bearing 7, guide groove 8, sail 9, steel rope 10, pulley 11, bearing 12, bearing pin.
Detailed description of the invention
A kind of automatic telescopic sail, comprise reel, mount pad, it is characterized in that, mount pad arranges runner, runner is fixed by bearing and bearing pin, connected by axle between two runners, the runner installation site in crane arm direction and the runner installation site in equilibrium arm direction are symmetrical about the cross-sectional plane of axle, and arrange guide groove between the axles, sail is arranged on axle by steel rope.
When working, started by reel, steel rope system work, sail realizes automatic telescopic.
