Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, a lifting frame for a circular chimney comprises a bottom plate 1, a rotating disk 2 connected with the bottom plate 1 through a rotating mechanism, speed reducing motors 3 are arranged on two sides of the rotating disk 2 symmetrically along the diameter direction, a winding roller 4 is arranged on one side of each speed reducing motor 3, a torque output shaft of each speed reducing motor 3 is connected with a rotating end of each winding roller 4, two clamping grooves are arranged on each winding roller 4, the winding has wire rope 5 on the draw-in groove, the outside of rotary disk 2 is equipped with outside extension's pull rod 6, rotates on the pull rod 6 and is connected with leading wheel 7, wire rope 5 keeps away from to walk around the one end of roller 4 and walk around leading wheel 7 and be connected with operation panel 8, the lower extreme of pull rod 6 is connected with telescopic link 9, the upper end of 8 one sides of operation panel is equipped with solid fixed ring 10, the outer wall of telescopic link 9 lower extreme is equipped with the screw thread, its flexible end of telescopic link 9 accessible passes solid fixed ring 10 and fixes with the nut.
