2. Construction load is greater than the design value in the hanging flower basket, and high tensile spring 6's length is compressed, and pointer 8 moves to the tie point direction of wire 91 and scale 7, and contact wire 91, the work of siren switch on power, send the photoelectricity sound alarm information. The constructor takes the unloading, the length of the high-strength spring 6 is recovered, the pointer 8 moves reversely, the alarm is powered off, the light-electricity and electricity-sound alarm information is stopped to be sent out, and if the constructor does not take the unloading, the alarm works all the time.
3. When the construction load in the hanging basket is smaller than a design value, the length of the high-strength spring 6 is compressed, the pointer 8 moves towards the direction of the connection point of the first lead 91 and the graduated scale 7, but the pointer does not contact the first lead 91, and the alarm does not work when the power supply is not switched on. In the construction process, when the weather is windy suddenly, the transverse load is increased, the stress of the steel wire rope 2 is increased, the length of the high-strength spring 6 is continuously compressed, the pointer 8 moves towards the connecting point of the graduated scale 7 and the first lead 91, the pointer contacts the first lead 91, the alarm is powered on to work, and the photoelectric sound alarm information is sent out. The constructor puts the hanging flower basket down to the ground, and the siren stops working.
The utility model discloses in can avoiding the work progress, the inside pulling force increase of wire rope under hanging flower basket overload, the strong wind weather condition leads to wire rope tension to surpass and calculate the rated load and cause the incident to take place.
Having thus described embodiments of the present invention, the foregoing description is intended to be illustrative, not exhaustive, and not limited to the embodiments disclosed, and many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
