[0029] See also Figure 1-3 A high-safety cantilever scaffold comprises a base 1, the inner side of the base 1 is provided with a stabilizing structure for preventing the scaffold from tipping over.

[0030] like Figure 1 As shown, the stable structure includes a motor 2 fixedly connected to the left side wall of the base 1, a threaded rod 3 fixedly connected to the output shaft of the motor 2, a threaded block 4 threadedly connected to the outside of the threaded rod 3, a first traction ring 5 fixedly connected to the upper surface of the threaded block 4, an oblique steel wire rope 6 bound to the inner side of the first traction ring 5, a second traction ring 7 bound to the other end of the oblique steel wire rope 6, a vertical plate 8 fixedly connected to the left side of the second traction ring 7, and a connecting block 9 fixedly connected to the bottom of the vertical plate 8.

[0031] A support assembly is provided on the left side of the connecting block 9 to improve the standing stability of the staff.

[0032] It should be noted that the bottom of the base 1 is fixedly connected to a bottom plate 10, the bottom of the bottom plate 10 is fixedly connected to a rubber pad 11, and a counterweight 12 is placed on the right side of the upper surface of the bottom plate 10. The arrangement of the bottom plate 10 and the rubber pad 11 increases the contact area between the base 1 and the ground, and the arrangement of the counterweight 12 further reduces the possibility of the base 1 tipping over.

[0033] The outer side of the threaded rod 3 is rotatably connected to the limit frame 13, and the top of the limit frame 13 is fixedly connected to the inner top wall of the base 1. The threaded block 4 is located on the inner side of the limit frame 13, and the width of the threaded block 4 is equal to the width inside the limit frame 13. The threaded block 4 is limited by the limit frame 13, so that the threaded block 4 can be moved by the threaded rod 3. The four corners of the bottom of the limit frame 13 are respectively fixedly connected with support feet 14, and the bottom of the support feet 14 is fixedly connected to the inner bottom wall of the base 1. The strength of the fixed support of the limit frame 13 is improved by the setting of the bracket 14. A sliding opening connected to the limit frame 13 is opened on the upper surface of the base 1, and the sliding opening is adapted to the first traction ring 5. The setting of the sliding opening allows the first traction ring 5 to move while binding the inclined wire rope 6.

[0034] The supporting assembly includes a fixing plate 15 fixedly connected to the left side of the connecting block 9, a rubber block 16 fixedly connected to the upper surface of the fixing plate 15, and a platform 17 fixedly connected to the upper surface of the rubber block 16. The rubber block 16 is provided to reduce the vibration of the platform 17, thereby ensuring the safety of the workers standing on the platform 17. The four corners of the bottom of the platform 17 are respectively fixedly connected with support rods 18, and the bottom ends of the support rods 18 are fixedly connected to the fixing plate 15. The four support rods 18 are evenly stressed, thereby improving the support safety of the platform 17.

[0035] A fence 19 is fixedly connected to the upper surface of the platform 17, and the inner side of the connecting block 9 is filled with shock-absorbing fluid. The fence 19 prevents workers from falling, and the shock-absorbing fluid further improves the shock-proof effect.

[0036] In addition, the electrical components (motor 2) mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for controlling a computer, etc., and the existing public power connection technology is not repeated in the text. A fixing frame is arranged on the outside of the motor 2, and the connection strength between the motor 2 and the inner wall of the base 1 is strengthened by the fixing frame, thereby improving the stability of the motor 2 during operation. The elastic objects such as the rubber pad 11 and the rubber block 16 can improve the support effect of the cantilever scaffolding to a certain extent. The rubber can play a role of shock absorption and buffering, reduce the impact and vibration of the supporting structure, and thus reduce the damage and deformation of the supporting structure. At the same time, the rubber can also increase the contact area between the scaffolding and the ground, and improve the stability of the scaffolding. The use of shock-absorbing fluid can play a certain role of shock absorption, reduce the vibration and impact of the scaffolding, and thus improve its stability to a certain extent. Attention should be paid to the selection and use of the shock-absorbing fluid, select the appropriate shock-absorbing fluid material and concentration, and conduct corresponding tests and inspections to ensure that it can play an effective role. During use, it is also necessary to regularly check and replenish the shock-absorbing fluid to ensure that it can continue to play a role.

[0037] The working principle of the above embodiment is:

[0038] The motor 2 drives the threaded rod 3 to rotate, and the threaded rod 3 drives the threaded block 4 to move in the opposite direction of the platform 17. The threaded block 4 drives the first traction ring 5 to move during the movement. The first traction ring 5 pulls the stand plate 8 through the inclined wire rope 6 and the second traction ring 7, so as to prevent the scaffold from turning outward when the worker stands on the platform 17;

[0039] In addition, when workers stand on the platform 17, the rubber blocks 16 absorb vibrations, and the four support rods 18 evenly support the platform 17, thereby strengthening the supporting effect of the platform 17 on the workers and improving the overall safety of the scaffolding.
