Claims

[Scope of Claim for Utility Model Registration] 1. An elevator frame on which a pillar is erected on the ground, a guide rail is constructed along the pillar, and an antenna is mounted on the guide rail so that it can be guided up and down. and a winch mechanism attached to a pillar for vertically guiding the elevating gantry frame, the antenna elevating device comprising: guiding the elevating gantry frame on which the antenna is installed up and down along the pillar by the winch mechanism. 2. The guide rail consists of a pair of C-shaped groove rods installed on a frame fixedly protruding from the pillars at appropriate intervals above and below, and the elevating frame is connected to both ends of the pair of vertical rods. an upper and lower plate, an upper underframe that protrudes from the front of the upper plate and has a bearing for the antenna shaft installed thereon, and a lower underframe that protrudes from the front of the lower plate and has a motor for rotating the antenna shaft installed. and a roller that is loosely suspended between a pair of arm rods protruding from the back surface of the upper and lower plates and fitted into the C-shaped groove rod, the lower end of which is connected to the rotating shaft of a motor installed on the lower frame. An antenna elevating device according to claim 1, wherein the connected antenna shaft is rotatably supported on a bearing of an upper frame. 3. The winch mechanism includes a winder installed at a lower position of the pillar, a sheave frame part installed at the upper end of the pillar and in which a sheave is pivotally supported, and a sheave frame extending from the winder. a cable connected to the upper plate of the elevating frame frame by passing around a sheave in the section;
Or the antenna lifting device according to item 2.
