Lifting device anti-rotation device for aerial lighting lifting device

The present invention relates to a lifting device anti-rotation device of the height-lifting lifting device, more specifically, when the height-lifting lifting body is lifted to the original position, holding and locking the lifting body firmly to restrain the shaking and rotation of the lifting body The present invention relates to a lifting body rotation preventing device of a height-lifting lifting device which prevents malfunction and damage of a light bulb provided in the lifting body and prevents a safety accident such as falling of the lifting body.

In general, hotel lobby, factory ceiling, gymnasium, and street lamps are installed with so-called luminaire lights, and these luminaire lights are installed at hotel lobby lamps at regular intervals due to the limited lifespan of bulbs, or at regular intervals. Lamps should be cleaned periodically.

As described above, the lighting is required to work by using a crane or ladder truck for aerial work in order to clean and replace the light bulb because of its configuration that the light bulb is placed in a high place.

However, the conventional method is more inconvenient than work on the ground, and the worker is exposed to the risk of heights such as electric shocks and falls, and many problems such as increased maintenance costs due to the use of additional equipment.

Therefore, in recent years, in order to solve the above problems, the height of the lighting device is provided with an automatic elevating device, the configuration of the main body is fixed to the upper side and the like, the lower part of the main body coupled to the contact and the lower bulb Lifting body equipped with a light fixture to be fixed, the wire is fixed on the drum at one end is fixed to the upper side of the lifting body and the other end, and the wire is unrolled / wound on the drum Its basic configuration is a forward and reverse motor for driving the drum so that it can be lowered and a control unit for controlling the forward and reverse motor.

In addition, the conventional luminescent lighting configured as described above transmits a falling signal to the control unit by using a wired button or a wireless remote controller provided on the ground to drive the stationary motor. This causes the drum, which is axially coupled to the stationary motor, to rotate, releasing the wires, and the lifting body descends to the ground.

Therefore, the conventional lighting device provided with the elevating device as described above has the advantage that it is possible to safely and conveniently carry out bulb replacement work, internal cleaning and repair work by lowering the elevating body to the ground.

However, when the lifting body is lifted up and engaged in the original casing, the lifting body is supported only by the wire, and when the pulling state of the wire is not maintained and the wire is extended or loosened, the contacted state is released and the bulb is not operated. In addition to the problems, the lifting and lowering of the lifting body caused by the wind or external force caused a problem, such as damage to the light bulb caused by the problem, as well as relatively high height lighting, such as chandeliers falling due to the weak support of the wire Safety accidents were inherent.

Therefore, the present invention has been devised to solve the conventional problems as described above, when the height of the height of the lifting body is lifted and coupled to the main body part in the home position, while holding the lifting body firmly and at the same time to lock the rest of the lifting body And it prevents the rotation, thereby preventing the malfunction and damage of the light bulb, as well as to provide a lifting device anti-rotation device of the height-lifting lifting device to prevent safety accidents such as falling of the lifting body.
