High pole lighting is the most effective and economical lighting method for large-area concentrated lighting. Lift-type high pole lights are widely used in highways, docks, airports, logistics offices, squares, stations and other places. The pole height is generally At 20~50m. High pole lamps are located in places where people, vehicles or cargo equipment are concentrated. The weight of the lamp panel installed with dozens of high-power floodlights can reach 500-1500Kg. The lamp panel can be lifted and lowered to achieve maintenance and repair of the lamps. If there is a lifting error, the lifting wire rope is broken, or the lamp panel rushes to the top, it will cause the lamp panel to fall from a high place, causing huge material losses and casualties. Therefore, the lifting system of the high pole lamp is the core technology of the high pole lamp, and the safety of the lifting system Safety is the key core of the lift-type high pole lamp. In view of the shortcomings of the existing technology, someone invented a lift-type high pole lamp (Patent No. CN02244273.1) in which the braking part and the hanging part of the lamp panel are the same part. However, its braking part uses a connecting rod. The rod type is not very sophisticated in terms of structural implementation, and it is not very convenient to replace the braking parts.
The technical problem to be solved by this utility model is to prevent the lamp panel from being raised and lowered incorrectly on the high pole lamp, from breaking the lifting wire rope, or from the lamp panel falling from a high place, thereby improving safety and avoiding causing huge material damage. losses and casualties.
In the high pole lamp anti-falling device of the present invention, the guide wheel frame of the guide wheel is connected to the guide seat. The rear end of the guide seat is connected to the guide brake seat through a pin, and there is a guide brake body on it. and a wire rope channel, which is characterized in that a braking mechanism is provided on one side of the guide wheel. There is a shoe ring outside the guide wheel. There is a brake spring between the shoe ring and the guide seat. The guide shaft is inside the spiral ring of the brake spring. There is a guide spring on the part inside the guide seat. The guide spring can make the guide wheel telescopic, and the maximum telescopic amount can reach 280mm. It can move the rod radially as the diameter of the rod changes, which improves the adaptability and facilitates maintenance. The brake spring allows the braking mechanism to move on the lamp panel. This improves safety by braking in a short time when the high pole lamp fails to rise or fall, the lifting wire rope breaks or the lamp panel falls from a high place.
Preferably, the stiffness of the brake spring is greater than that of the guide spring, so that when the lamp panel falls and the guide brake body cannot move, the guide wheel will move slightly away from the diameter of the pole lamp under the action of the brake spring. Move, so that a certain gap is formed between the guide wheel and the surface of the pole. This gap can be 1~6mm. The taper size is related to the gap. Generally speaking, the larger the taper, the smaller the gap. When the rope breaks, the lamp panel will fall. Since the lamp pole is small on the top When the taper is increased, the gap will be reduced, and the front end of the braking mechanism will be wedged into the gap as the gap decreases, reducing the impact of sliding and the braking distance, forming a buffering effect before braking.
