In the past, outdoor spaces requiring bright lighting at night, such as parks, airports, or harbors, have been installed and operated with light towers with a plurality of lamps mounted on the top of the props. It is true that such a conventional lighting tower faithfully performs the original function of brightly illuminating the outdoor space at night, but when the lighting is broken, a worker climbs directly to the upper part of the prop using a ladder car to replace or repair the lighting. However, there was a deficiency to bear the hassle and risk of maintenance.

On the other hand, the present applicant was filed in 1994 Utility Model Registration Application No. 10298, 1998.

He holds the right of 'Light Tower' registered as Utility Model Registration No. 124767 as of 06.16. The light tower said, "The hanging lamps are suspended from the outside ropes and placed over the top of the pylon. The inner ropes connected to the outer ropes are wound around a drum installed near the inner bottom of the towers and connected to the reducer dynamically. ", By installing a coupling on the input shaft of the reducer and concealing it in the steel tower, and selectively connecting the shaft of the external steering wheel or the rotating shaft of the motor to the shaft connection hole of this coupling, to enable the lamp to be unloaded or raised. It was made into technical summary.

In addition, in 2000, a utility model registration application No. 28895 was filed by a third party in connection with a lighting tower, and the utility model registration of Utility Model Registration No. 218042 discloses a 'locking device for a descending light tower'. The locking device of the lifting tower is "a mobile unit having a large number of lights installed at appropriate intervals, a support which is located at the center of the mobile unit and fixed vertically to the ground, and a fixed body which is installed on the top of the support and covered with a cover.

In this case, between the support plate fixed to the appropriate position of the upper outer portion of the mobile unit eccentrically connected to the pivot pin to be pivotally installed, and the fixed body portion is installed so as to lock while contacting the upper and lower positions of the inner curved groove of the latch "Consisting of a locking pin" as the technical gist.

All of the preliminary proposals disclosed above are provided with a fixing frame at the top of the support, and are suspended or lifted up and down by lifting a lifting frame with a lighting lamp as a wire which is pulled or released through the fixing frame by a winch installed at the bottom of the support. As a configuration, it is true that it has the advantage of not only brightly illuminating the outdoor space at night, but also lowering the lifting frame to replace or repair the broken lights more conveniently and safely.

However, these preliminary registrations are commonly provided with a locking pin on the fixing frame of the upper portion of the strut, and an eccentric pivoting latch is attached to the lifting frame so that the elevated lifting frame can be fixed by the locking hooks that hang on the locking pins of the fixing frame. As a structure, as the lifting frame is not tightly fixed to the fixed frame, it is not only to reduce the sense of stability, but also when the lifting frame is subjected to a cross wind, it shakes violently and repeatedly causes collisions with the fixed frame, causing noise. It has been accompanied by problems such as frequent occurrence of damage caused by repeated impact of the lifting frame and the surrounding components.

The present invention is intended to provide a lifting light tower that is configured to be tightly constrained lifting frame toward the fixing frame installed on the top of the support, to maintain the stable fixed state when the first use. Secondly, the aim is to provide a lifting light tower that allows avoiding repeated collisions between the lifting frame and the surrounding components.
