Description

Lifting High Mast Light

technical field

The utility model relates to a lifting type high pole lamp.

Background technique

High pole lights generally refer to a new type of lighting device composed of a steel cylindrical light pole over 15 meters and a high-power combined light frame, which can be divided into non-lifting high pole lights and lifting high pole lights. The installation and maintenance of non-lifting high pole lights are not very convenient. Therefore, in order to facilitate maintenance and replacement, lifting high pole lights are generally used at present. Elevating high pole lights are generally composed of light poles, light stands, lighting appliances, light stand lifting mechanisms, top lightning protection devices and bottom foundation parts. They are often used in city squares, stations, docks, freight yards, highways, stadiums and overpasses. Area lighting premises.

The lifting mechanism of the existing lifting type high pole lamp often adopts the lifting mechanism of the mechanical transmission mode of the rope wheel transmission. Powered by the motor, after passing through the deceleration mechanism, it drives the reel to wind forward and reverse or loosen the wire rope to realize the lifting function. According to the relevant provisions of the Ministry of Construction CJ/T3076-1998 Technical Conditions for High-pole Lighting Facilities, when using a single steel wire rope as the main lifting rope, it should have an automatic unloading device, that is, the lamp panel can be hung on the lamp panel reliably after it is raised to the right position. on the rod to unload the traction wire rope.

The current lifting mechanism often uses steel wire rope to directly pull the lamp panel, or hook it with a hook, or support it with a screw rod. For example, a "lifting high pole lamp" disclosed in Chinese Utility Model Patent No. 02260831.1 is equipped with a hanging sleeve under the pole top frame, a hook is provided on the upper plane of the lamp panel, and a convex surface with a slope is provided on the inner surface of the hanging sleeve. The block and the groove, the cylindrical pin that traverses the hook body, falls into the groove to realize the unloading of the cable when hanging. The hook unloading mechanism has the problems of unhooking and unobvious hook indication, especially when multiple hooks are used, affected by the high-altitude wind speed, the lamp panel will be unbalanced, resulting in multiple hooks not being able to successfully complete the turning and hooking at the same time situation, which will easily cause the lamp panel to fall, causing great danger.

China Utility Model Patent No. 200920169997.8 discloses "a double-lifting high pole lamp", which includes a pole body, a camera disc on the upper part of the pole body, and a lamp panel fixed on the top. There is a lifting structure connected with the lifting camera disc and the lamp panel. The lifting mechanism of the lamp panel is directly above the lifting mechanism of the camera disc. Its rope extends upward along the central axis of the rod body and is divided into After three strands, it is connected with the lamp panel. After the camera panel and the lamp panel are raised, they still need to be pulled closer with the help of ropes. There is no additional traction rope unloading mechanism, so it is not safe to use and does not comply with relevant regulations.

Chinese invention patent application number 201310156525.X discloses a "lifting high pole lamp", which includes a hollow lamp pole, a lifting screw is arranged inside the hollow lamp pole, and a control handle for controlling the rotation of the lifting screw is arranged outside the hollow lamp pole A threaded sleeve is provided in the hollow light pole, and the threaded sleeve is threadedly matched with the lifting screw rod. The threaded sleeve is connected with a lifting rod, and a pin and a lamp holder are arranged at the end of the lifting rod, and a light bulb is connected with the lamp holder. When the bulb is broken and needs maintenance, turn the control handle to rotate the lifting screw rod, so that the lifting rod and the bulb are lowered together. It can be seen that the invention uses a long lifting screw to lift and support the lamp panel. Since the height of the high pole lamp is generally more than 15 meters, the height of the lifting screw is also about 15 meters. The long lifting screw rod carries the lamp panel for a long time, which will cause deformation, which will cause the lifting rod and the light bulbs on it to fail to descend, so its lifting structure is unstable.
