Description

Multistage Lighting Tower {MULTISTAGE LIGHTING TOWER}

The present invention relates to a multi-stage lighting tower, and more particularly to smooth lifting and lowering of each cylinder forming a multi-stage structure, as well as a solid installation structure to prevent damage to the wire cable to extend the service life and durability against wind pressure It relates to a multi-stage lighting tower that can improve the appearance and provide a beautiful appearance.

In general, the lighting tower is mainly installed in a large place that requires lighting at night, such as a road or a playground for a night game or a golf course, so as to illuminate the widest area in a relatively high place.

It is desirable that the lighting tower has a height of at least 10M, and the multi-stage configuration is mainstream to facilitate management according to periodic cleaning or tower maintenance.

In particular, the method of adjusting the height of the multi-stage lighting tower is divided into mechanical and hydraulic. In the case of the hydraulic lighting tower, the tower is difficult to maintain and repair due to the use of oil of high pressure, and the top and the top of the tower are lowered. The operation is slow, and the hydraulic oil is exposed from each cylinder to pollute or pollute the surrounding environment, and since the rod is circular, it has a problem such that it is easily bent due to poor adaptability to wind pressure. Recently, mechanical lighting towers have been favored.

Thus, the mechanical lighting tower having a multi-stage structure secures one end of the wire rope to a lighting stand, and the other end is fixed to a drum installed inside the pylon, and the drum rotates forward and reverse according to the driving of the motor to form a steel tower. The tower is constructed to be stacked in multiple stages, or it is configured to adjust the height while allowing the nested stages to step out.

However, since these various lighting towers are installed on the ground almost on the ground, the height difference between the overlapping stages basically allows the operator to check and repair without a separate ladder. There was a limit to lowering the height of descent.

In addition, due to the cutting of the wire connected to the lamp while in use, there is a risk that the device is damaged, parts such as wire or rollers, wire cables, etc. are exposed to the outside of the tower to reduce the appearance of the light tower.

Moreover, there are problems in that externally exposed parts are easily corroded or damaged in the air, thereby shortening the service life of the device.

In particular, since the column heads of the above-mentioned hydraulic or mechanical lighting towers mostly form a circular structure, there is a problem in that a twisting phenomenon occurs frequently during the lifting and lowering operation.

The present invention is devised to solve all the problems of the prior art as described above,

The purpose of the present invention is to combine the advantages of hydraulic and mechanical lighting tower in the multi-stage lighting tower, to ensure the smooth installation and lifting operation of each cylinder with a solid installation structure of the tower as well as to supply power It is to provide a multi-stage lighting tower that can improve the appearance by preventing the wire cable from being exposed to the outside.

Another object of the present invention is to make the outer shape of each cylinder constituting the tower to form a square pipe shape, thereby preventing the torsional phenomenon caused by wind pressure during the lifting and lowering operation of each cylinder to the maximum, and smooth installation and continuous installation To keep it going.

Multi-stage lighting tower of the present invention for achieving the above object is a power supply main body fixedly installed on the ground, a fixed cylinder fixed to the upper side of the main body to form a large diameter, and step by step from the upper side of the fixed cylinder It includes a plurality of movable cylinders to be moved up and down, and a lighting stand fixed to the top of the movable cylinder, the movable cylinder is connected to the chain according to the up and down operation of the hydraulic cylinder mounted inside the fixed cylinder, respectively By allowing the fourth cylinder, the third cylinder, the second cylinder, the first cylinder to move up and down in a smooth manner, the height of the tower can be adjusted, thereby achieving the above object.
