的とする。By the way, in the conventional fixed-type observation tower, an elevator that reciprocates between the observation room above the observation tower and the ground is required, and the tower becomes higher as the height of the observation tower increases. The construction cost of the structure itself also increases significantly. Therefore, it is conceivable that the viewing cabin structure can be moved up and down along the tower, or the observation tower can be lifted by a hydraulic jack, etc., but both require a large-scale power unit. There is a problem. The present invention is intended to solve such problems, and by making the observation tower extendable and retractable, by providing a counterweight that is linked to the extension and contraction operation,
It is an object of the present invention to provide an up-and-down telescopic observation tower that is easy to construct and that can significantly reduce the required power during operation.

い。The wire 17a of the electric hoisting machine 17 is connected to the counterweight 14 as a drive mechanism for vertically expanding and contracting the tower-like structure by promoting vertical movement of the counterweight 14. The wire 17a may be directly connected to the lowermost wire 8. With the above-mentioned configuration, the counterweight 14 is moved along with the pulling operation of the electric hoist 17.
When the lowering of the tower is promoted, the wires 8 are sequentially interlocked with each other to construct the tower structure 2.
Increase ~ 5. Further, when lowering the tower constructing bodies 2 to 5, the wire 17a of the electric hoisting machine 17 may be operated so as to prompt the counterweight 14 to rise.

で、作業の安全性を向上させることができる。In the means for lifting the tower body by a hydraulic jack or the like, a large amount of energy for lifting the total weight of the tower body is required, and the lifting device becomes large in size. Since the tower components 2 to 5 are linked to the counterweight 14 via the pulley 7 and the wire 8 so as to be interlocked with each other, the total weight of the lifting portion and the counterweight 14 are combined. If the weight ratio is set to a constant value in consideration of the driving force, the ascending operation can be performed with energy corresponding to only the weight of the viewer. Further, since the erection work of each of the tower components 1 to 5 of the tower-like structure and the viewing cabin structure 6 can be carried out near the ground, the work safety can be improved.
