The inside is vertically hollow, and is erected on the ground. A winding drum 2 is installed in the lower part of the pole 1 so as to be freely rotatable, and the winding wire 4 wound around the winding drum 2 is led out to the upper end of the pole 1. The end of the winding wire 4 is introduced into the pole 1 again by hanging it over the winding wire pulley 5 attached to the winding wire pulley 5, and the end of the winding wire 4 is passed through the balance weight 3 disposed inside the pole 1 so as to be movable up and down. It is combined. A through hole 13 is provided in the center of the balance weight 3, and the winding wire 4 directed upward from the winding drum 2 is passed through the through hole 13.
The elevating pedestal 7 is formed in a cylindrical shape, has a lighting device 6 attached to its outer periphery, and is disposed on the outer periphery of the pole 1 so as to be vertically movable. The elevating frame 7 is connected to the balance weight 3 by a plurality of hanging wires 9 attached to the upper end of the pole 1 and each hanging from a pulley 8 for hanging wires. here,
The weight of the elevating frame 7 (including the weight of the lighting fixture 6) is made lighter than the weight of the balance weight 3. Further, an opening 12 is formed in the upper side surface of the pole 1, and a stopper 11 is disposed in the opening 12 so as to protrude and retract freely, and between a base piece 14 at the base of the stopper 11 and the inner circumference of the pole 1. Tension spring 1
The stopper 11 is biased by a spring 10 so as to protrude outward from the opening 12. A winding wire 4 extending upward from the winding drum 2 is passed through the stopper 11.

するものである。 Therefore, when setting the elevating frame 7 on the upper end of the pole 1, the winding drum 2 is rotated in the direction in which the winding wire 4 is sent out, and the balance weight 3 is lowered. The lifting frame 7 is pulled up using the hanging wire 9.
At this time, since the weight of the balance weight 3 is heavier than the weight of the lifting frame 7, the weight difference due to the balance weight 3 causes the lifting frame 7 to
By abutting against and press-contacting the lower surface of the periphery 5, the elevating frame 7 is held on the upper end of the pole 1, and in this state it is used for illumination. Also, at this time, since the weight of the lifting platform 7 is supported by the balance weight 3, no tension is applied to the winding wire 4 (the winding drum 2 can rotate freely).
As shown in FIG. 1, no tensile force is applied by the winding wire 4 to pull the stopper 11 into the pole 1, and the stopper 11 projects outward from the opening 12. Here, if the hanging wire 9 is cut, the balance weight 3 will fall, but since the winding drum 2 rotates freely, no tension will be applied to the winding wire 4 even if the balance weight 3 falls. The stopper 11 is maintained in a protruding state, and the lifting gantry 7 is prevented from falling by the stopper 11, thereby preventing an accident due to the lifting gantry 7 falling.

ポール１内に引込めることできるものである。 Next, when lowering the elevating frame 7 for maintenance and inspection, etc., the winding drum 2 is rotated in the direction in which the winding wire 4 is wound, and the balance weight 3 is rotated.
The lifting frame 7 is lowered by raising the balance weight 3.
is pulled up by the winding wire 4, so tension is applied to the winding wire 4, and the tension of the winding wire 4 causes the stopper 11 to move inward against the biasing force of the spring 10, as shown in FIG. By pulling the stopper 11 into the pole 1, the lifting frame 7 can be lowered as shown in FIG. 3 without any hindrance caused by the stopper 11. Also, at this time, there is a gap c between the stopper 11 and the lower end of the lifting platform 7 located at the upper end of the pole 1.
is formed, so the stopper 11 and the elevating frame 7
There is no fear that a frictional force will be generated between the two and the stopper 11 can be smoothly retracted into the pole 1 by the tension of the winding wire 4.

きるものである。 In addition, when raising the elevating frame 7 from the lowered state, the winding drum 2 is rotated slowly while the balance weight 3 is lowered, so that tension is applied to the winding wire 4 as shown in FIG. The tension of the winding wire 4 causes the stopper 11 to be retracted into the pole 1, so that the lifting platform 7 can be raised without the stopper 11 getting in the way.

きるものである。 As described above, in the present invention, when the lifting frame is raised or lowered, the stopper is automatically retracted into the pole by the tension of the winding wire, and the fall prevention of the lifting frame is released. This can be done automatically, and when the lifting frame is raised to the top of the pole and set, the tension on the winding wire is loosened and the stopper automatically protrudes from the pole, automatically preventing the lifting frame from falling. It is something that can be done. In addition, since the elevating frame is made lighter than the balance weight,
Due to the difference in weight, the elevating frame can be maintained in a set state on the upper end of the pole, and no special means for maintaining the set state of the elevating frame is required. Furthermore, since a gap is formed between the stopper and the lower end of the lifting pedestal located at the top end of the pole, there is no fear of frictional force occurring between the stopper and the lifting pedestal, and the tension of the winding wire allows smooth movement. The stopper can be retracted into the pole.
