Embodiment 1

[0038] Example 1. An acousto-optic alarm for a trolley of a tower crane and / or a hook landing point indicating lighting device, comprising a solar panel 1, a solar charge and discharge controller 2, a rechargeable battery 3, a remote control switch module 7, a voice acousto-optic alarm 9, Warning lighting device 10, electrical protection device and other components. The device of the present invention uses high-efficiency, high-reliability, waterproof and dustproof electronic components, and uses a high-strength steel structure shell to be installed on a load trolley of a tower crane. The device circuit diagram of the present invention is as figure 1 As shown, the electrical physical diagram is shown in figure 2 shown. Voice sound and light alarm 9 is connected in parallel with warning lighting device 10 and forms load circuit with remote control switch module 7 and air switch B6; rechargeable battery 3 forms power supply circuit with fuse 4, air switch A5 and battery char...

Embodiment 2

[0041] Example 2. The device of the present invention is fixed by a detachable installation method. Operations involving the need to climb up the tower crane should be completed by professional maintenance personnel of the hoisting machinery, with the cooperation of the driver and the commander. A method for installing an audible and visual alarm and / or hook lifting and landing point indicating lighting device for a trolley of a tower crane, comprising the following steps:

[0042] 1. Buy the components listed in the attached table in the market. The sound and light alarm 9 adopts a circular arc-shaped metal horn. Red highlight flashing and music (warning quotations) playing function, let the merchant store the music and warning quotations files before purchasing; the warning lighting device 10 adopts a bunch of light spotlights with an effective range of about 100m. Figure 4 For the special danger signal spot shown, the diameter of the spot at a range of 100 meters is abou...

Embodiment 3

[0046] Example 3. A method for using an audible and visual alarm for a trolley of a tower crane and / or a hook lifting and landing point indicating lighting device, comprising:

[0047] The tower crane driver uses the switch remote control 8 supporting the remote control switch module 7 to open the device of the present invention when going to work, and it sends a red highlight flash, a special yellow light beam and music (warning quotations); use the switch remote control 8 to close when off duty That's it. When the device of the present invention is working normally, the driver can use the remote controller B carried by the voice sound and light alarm device 9 to adjust the volume, switch tracks or turn off the voice sound and light alarm device, and can use the remote controller A carried by the warning lighting device 10 Turn off and turn on the warning lighting device to meet the requirements of different usage time and scenarios. When it is necessary to recharge the rec...

Abstract

The invention discloses a tower crane load trolley sound-light alarm and / or lifting hook landing point indication lighting device and an installing and using method thereof. The tower crane load trolley sound-light alarm and / or lifting hook landing point indication lighting device is characterized in that a voice sound-light alarm and a warning lighting device are connected in parallel and then form a load circuit with a remote control switch module and an air switch B, a rechargeable battery, a fuse, an air switch A and a battery charger interface form a power supply circuit, a solar cell panel and a rechargeable battery are used for supplying power together, the power supply circuit is connected to a battery terminal of a solar charging and discharging controller, the load circuit is connected to a direct current output end of the solar charging and discharging controller, and the solar cell panel is connected to a solar cell panel input end of the solar charging and discharging controller. According to the invention, cross operators on a hoisting site can sense the relative positions and motion states of the lifting hook and a hoisted object through the binaural effect, and a special dangerous signal light spot can be formed at the ground vertical projection of the lifting hook, so that operators near the lifting hook are reminded to avoid danger in advance and would take precautions if an object fell from a high place during the hoisting.

Description

technical field [0001] The invention belongs to the technical field of construction hoisting machinery, and in particular relates to an acousto-optic alarm and / or hook landing point indicating lighting device installed on a trolley of a tower crane and an installation and use method thereof. Background technique [0002] Construction hoisting machinery is one of the most important machinery in the infrastructure industry such as housing construction, and the situation of accidents and safety hazards is not optimistic. For example, there will be a major casualty accident on a tower crane every three days on a construction site, which not only causes a large number of casualties, but also brings huge economic losses. According to Heinrich's law of accidents, numerous accidents in the same activity will inevitably lead to the occurrence of major casualties. To prevent the occurrence of major accidents, we must pay attention to the signs of accidents, reduce and eliminate near ...
