Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Refer to the instruction manual appendix Figures 1-5This utility model provides a stabilizing device for an operating frame used in the construction of a tower crown steel structure, including two arc-shaped fixing plates 1. One end of the two arc-shaped fixing plates 1 is connected by a pivot hinge 2, and the other end of the two arc-shaped fixing plates 1 is fixed together by two fastening bolts 3. Furthermore, two vertically distributed connecting holes 9 are machined on each of the two arc-shaped fixing plates 1, and the connecting holes 9 on the two arc-shaped fixing plates 1 are used to install the fastening bolts 3. Rubber gaskets 10 are fixedly provided on the inner walls of the two arc-shaped fixing plates 1.

[0026] Next, a connecting rod 6 is connected to the outer wall of one of the arc-shaped fixing plates 1 via a bearing 5. Specifically, the outer wall of the connecting rod 6 is connected to the inner ring of the bearing 5, and the outer ring of the bearing 5 is connected to the arc-shaped fixing plate 1. One end of the connecting rod 6 is connected to a steel pipe 7 via a rotating shaft. The steel pipe 7 is used to connect the scaffolding, and an extension component 8 is sleeved on the outer wall of the steel pipe 7.

[0027] In actual use, the installers first place the two arc-shaped fixing plates 1 onto the tower crown steel column, and then use fastening bolts 3 and nuts to firmly connect the two arc-shaped fixing plates 1 together. The rubber gaskets 10 on the inner wall of the arc-shaped fixing plates 1 are tightly fitted to the outer wall of the tower crown steel column. The rubber gaskets 10 can not only fill the small gap between the arc-shaped fixing plates 1 and the steel column, but also increase the friction, improve the sealing performance and firmness. After that, the installers adjust the angle of the connecting rods 6 and the steel pipes 7 according to the position of the scaffold, and then connect the steel pipes 7 and the extension components 8 to the fasteners on the scaffold, thus completing the connection and fixation between the scaffold and the tower crown steel column, thereby improving the stability of the scaffold.

[0028] In this embodiment, a protective component 4 for protecting the fastening bolt 3 is also provided between the two arc-shaped fixing plates 1. Specifically, the protective component 4 includes a protective shell 41. The outer walls of the two arc-shaped fixing plates 1 are machined with slots 42. The protective shell 41 is inserted into the slots 42, and the inner wall of the protective shell 41 abuts against the outer wall of the fastening bolt 3. By using the protective shell 41 to cover the fastening bolt 3 and the nut, the stability of the fastening bolt 3 can be improved, thereby improving the connection strength of the two arc-shaped fixing plates 1, and at the same time improving the corrosion resistance of the fastening bolt 3.

[0029] Furthermore, multiple rubber protrusions 43 are fixedly provided on the inner walls of both slots 42, and the inner walls on both sides of the protective shell 41 are machined with the same number of slots 44 as the rubber protrusions 43. The rubber protrusions 43 are engaged with the slots 44, which facilitates quick installation and removal of the protective shell 41 by the installer.

[0030] Refer to the instruction manual appendix Figures 1-4The extension assembly 8 includes an extension tube 81 sleeved on the outside of the steel pipe 7. A limiting plate 82 is fixedly provided on the outer wall of the steel pipe 7. A limiting groove 83 adapted to the limiting plate 82 is processed on the inner wall of the extension tube 81. The limiting plate 82 is provided in the limiting groove 83 to improve the stability of the extension tube 81 when it moves.

[0031] A rectangular groove 84 is machined at the top of the steel pipe 7. A guide rail 85 is fixedly installed inside the rectangular groove 84. A lead screw 86 is rotatably connected inside the guide rail 85. A nut block 87 is threaded onto the lead screw 86. The nut block 87 is detachably connected to the extension pipe 81 by bolts. A storage groove 88 is machined at the end of the steel pipe 7 away from the connecting rod 6. A handle 89 is provided in the storage groove 88. The handle 89 is fixed to the lead screw 86.

[0032] When the length of steel pipe 7 is insufficient to connect with the scaffolding, the installer turns handle 89 to rotate screw rod 86. When nut block 87 on screw rod 86 moves, it moves extension pipe 81 along with it. Under the limit of limit plate 82, extension pipe 81 is stably removed from steel pipe 7. Then the installer can connect extension pipe 81 to scaffolding coupler without replacing steel pipe 7. This can better meet the scaffolding installation requirements and improve installation efficiency. After extension pipe 81 is adjusted to the appropriate position, screws can be set on handle 89 to fix handle 89 and prevent screw rod 86 from rotating during use, causing the position of extension pipe 81 to change.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
