[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The embodiment of the present application discloses a scaffolding structure for demolishing an illegally built chimney.

[0036] Example 1

[0037] Reference Figure 1 , 2 3. 4. A scaffolding structure for demolishing an illegally built chimney, comprising a chimney 1, a fixed block 101 clamped on the outer wall of the chimney 1, an expansion and folding mechanism 2, comprising a long groove 201 opened around the upper surface of the fixed block 101, a rotating block 202 is manually inserted into the long groove 201, a round groove 203 runs through the surface of the rotating block 202, a rotating column 204 runs through and is rotatably connected to the upper end of the rotating block 202, one side of the rotating block 205 is rotatably connected to the outer wall of the rotating column 204, a square hole 206 runs through and is opened inside the rotating block 205, the middle part of the upper and lower ends of the square hole 206 is fixedly connected to the auxiliary column by welding, and a gear 207 is movably connected to the square hole 206 The outer wall of the auxiliary column, the tooth grooves of rack 1 208 and the teeth of gear 207 are engaged to realize the movement of rack 1 208, the tooth grooves of rack 209 and the teeth of gear 207 are engaged to realize the movement of rack 209, one side of the extension block 210 is fixedly connected with one side of rack 1 208 by welding, one side of the other extension block 210 is fixedly connected with one side of rack 209 by welding, one end of the two clamping blocks 211 are fixedly connected with the upper and lower end surfaces of the middle part of the square hole 206 by adhesive, the upper surface of the sliding plate 1 212 is fixedly connected with the rack 1 208 by welding, and the lower surface of the sliding plate 213 is fixedly connected with the rack 2 209 by welding.

[0038] By setting up, the operator will sleeve and fix the fixed block 101 on the outer wall of the chimney 1 before building the scaffolding. After fixing the fixed block 101 on the outer wall of the chimney 1, the operator manually turns to open the rotating block 1 202 and the rotating block 2 205. At this time, the rotating block 1 202 and the rotating block 205 are rotatably connected to the surface of the rotating column 204. After the rotating block 1 202 and the rotating block 205 are rotated to an angle greater than ninety degrees, the rotating block 1 202 is inserted into the long groove 201. At this time, the rotating block 205 begins to rotate downward due to its own weight. When the lower surface of the rotating block 205 contacts the upper surface of the fixed block 101, the upper surface of the fixed block 101 will press the rotating block 205, so that the operator can work on the upper surface of the rotating block 205.

[0039] When the operator needs to go from one side of the chimney to the other side, he pulls the sliding plate 1 212 or the sliding plate 213 inside the rotating block 205. At this time, the pulled sliding plate 1 212 or the sliding plate 213 starts to slide outward in the square hole 206. As the sliding plate 1 212 or the sliding plate 213 slides outward in the square hole 206, the rack 1 208 fixedly connected to the upper surface of the sliding plate 1 212 and the rack fixedly connected to the upper surface of the sliding plate 213 are Rack 1 208 or rack 209 209 slides along with sliding plate 1 212 or sliding plate 213. Since the sliding rack 1 208 or rack 209 is meshed with gear 207, when one of sliding plate 1 212 or sliding plate 213 is pulled, the gear 207 meshes, so that rack 1 208 or rack 209 on the other side starts to move outward at the same time. When sliding plate 213 slides to the upper end of sliding plate 1 212, the operator can go from one side of the chimney to the other side.

[0040] Reference Figure 1 , 2, 5, 6, the fixing mechanism 3, including a threaded column 301 movably penetrating the interior of the fixing block 101 and the round groove 203, an active cavity 1 302 non-penetratingly provided in the interior of the threaded column 301, a sliding column 1 303 movably connected to the interior of the active cavity 1 302, an annular groove 304 non-penetratingly provided on the surface of the sliding column 1 303 in the active cavity 1 302, a boss cavity 305 non-penetratingly provided on the side wall of the sliding column 1 303, one end of the sliding column 2 306 is fixedly connected to one end of the sliding column 1 303 by an adhesive, and the sliding column 2 306 is away from the sliding column 1 303 One end is slidably connected to the inside of the boss cavity 305, and the two ends of the spring 307 are fixedly connected to one side of the sliding column 303 and the side wall of the boss cavity 305 by welding. The square groove 308 is non-through and symmetrically opened on the surface of the threaded column 301, and the upper and lower ends of the fixed column 309 are fixedly connected to the upper and lower end surfaces of the square groove 308 by welding. The rotating rod 310 is movably connected to the outer wall of the fixed column 309 and slidably connected to the inside of the square groove 308. The rotating rod 310 is also stuck in the annular groove 304, and the rotating ring 311 is threadedly connected to the thread on the surface of the threaded column 301.

[0041] The threads on the surface of the threaded column 301 are arranged on the outer wall of the threaded column 301 at one end away from the fixing block 101 .

[0042] By setting, when the rotating block 1 202 is inserted into the long groove 201, the operator grasps the outer wall of the threaded column 301 and presses the sliding column 1 303 on one side of the threaded column 301. When the operator presses the sliding column 1 303, the sliding column 1 303 starts to slide toward the inside of the active cavity 1 302. When the sliding column 1 303 slides in the active cavity 1 302 toward the inside of the active cavity 1 302, the sliding column 2 306 fixedly connected to one side of the sliding column 1 303 starts to slide toward the inside of the boss cavity 305. At the same time, the sliding column 1 303 and the sliding column 2 306 fixedly connected to ... The spring 307 on the side and side walls of the boss cavity 305 begins to shrink, and the rotating rod 310 connected to the outer wall of the fixed column 309 is rotated. Through the sliding of the sliding column 303, one end of the rotating rod 310 stuck in the annular groove 304 is resisted, and the rotating rod 310 begins to rotate on the outer wall of the fixed column 309 toward the inside of the square groove 308. When the rotating rod 310 is completely rotated to the inside of the square groove 308, the threaded column 301 can be pulled out from the inside of the fixed block 101 and the round through groove 203 (or the threaded column 301 can be inserted into the inside of the fixed block 101 and the round through groove 203).

[0043] When the screw column 301 is inserted into the fixed block 101 and the round groove 203, the operator manually releases the pressed sliding column 1 303. At this time, the spring 307 fixedly connected to the side wall of the boss cavity 305 begins to extend, pushing the sliding column 1 303 back to the initial state. In the process of the sliding column 1 303 returning to the initial state, the rotating rod 310 in the annular groove 304 slides through the sliding column 1 303, and the rotating rod 310 begins to rotate on the outer wall of the fixed column 309 and gradually slides out of the square groove 308. The sliding rotating rod 310 can fix the inside of the rotating block 1 202. After fixing, the rotating ring 311 on the surface of the screw column 301 is rotated. The screw column 301 is fixed on the outer wall of the fixed block 101 by rotating the rotating ring 311. At this time, the outside of the rotating block 1 202 can be fixed, and the operator can stand stably above the rotating block 205 to work.

[0044] The implementation principle of the scaffolding structure for demolishing an illegally built chimney according to the embodiment of the present application is as follows: the operator opens the folded rotating block 1 202 and the rotating block 205. After opening, the operator inserts the rotating block 1 202 into the long groove 201. After completion, the lower surface of the rotating block 205 is made to fit with the upper surface of the fixed block 101. Then, the threaded column 301 is manually grasped, and the sliding column 1 303 is pressed to rotate the rotating rod 310 to the inside of the square groove 308. When the rotating rod 310 is rotated to the inside of the square groove 308, the threaded column 301 is inserted into the inside of the fixed block 101 and the round groove 203. After completion, the sliding column 1 303 is released, and the rotating block 202 can be adjusted by the rotating rod 310. The interior of the rotating block 102 is fixed. At this time, the rotating ring 311 is rotated to make the rotating ring 311 fit against the outer wall of the fixed block 101, so that the external fixation of the rotating block 102 can be completed. After fixation, work can be started. When the operator needs to go from one side of the chimney to the other side, the sliding plate 1 212 or the sliding plate 213 is manually pulled out. By rotating the gear 207, the standing area required for work can be increased. When disassembly is required, the sliding column 1 303 is pressed to make the rotating rod 310 return to the square groove 308, and the threaded column 301 can be pulled out from the fixed block 101 and the round groove 203, and the rotating block 1 202 inserted into the long groove 201 is folded to complete storage and disassembly.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
