The gear 15 is located on the outside of the gear ring 16. The gear 15 meshes and rotates with the gear ring 16. The upper surface of the turntable 3 is fixedly connected with a support plate 4 for providing support for the mounting frame 6 and other components. A limiting groove 18 is provided on the upper surface of the base plate 2. The limiting groove 18 is provided on the upper surface of the base plate 2 to limit the movement range of the turntable 3 and the gear ring 16 to ensure that they can rotate stably. The turntable 3 and the gear ring 16 are both located inside the limiting groove 18. The turntable 3 and the support plate 4 are both located on the outside of the chimney 1. The support plate 4 is provided with an inlet and outlet 5, through which the working platform 17 enters and exits the chimney 1. The inlet and outlet 5 penetrates the support plate 4 and the chimney 1.

[0024] The mounting frame 6 is fixedly connected to the upper end of the support plate 4, and provides a mounting position for the motor A7, the screw rod 8 and other components. The mounting frame 6 is located directly above the chimney 1. The left surface of the mounting frame 6 is fixedly connected to the motor A7, which drives the screw rod 8 to rotate, thereby driving the moving frame 9 to move on the screw rod 8. The output end of the motor A7 is fixedly connected to the screw rod 8, and the linear movement of the moving frame 9 is achieved by rotation. The screw rod 8 passes through the mounting frame 6 and extends to the inside of the mounting frame 6. A limiting hole is set on the right inner wall of the mounting frame 6 to limit the rotation of the screw rod 8. The end of the screw rod 8 away from the motor A7 is located at the limiting hole. Inside the positioning hole, the side surface of the screw rod 8 is rotatably connected to a movable frame 9, which is rotatably connected to the screw rod 8 and can move on the screw rod 8, and is fixed with a motor B10 and a wire-taking mechanism of a working platform 17. The rear surface of the movable frame 9 is fixedly connected to the motor B10 for driving the wire-taking wheel 11 to rotate. The output end of the motor B10 is fixedly connected to the wire-taking wheel 11 for contracting the rope 12. The side surface of the wire-taking wheel 11 is rotatably connected to the rope 12. The lower end of the rope 12 is fixedly connected to the working platform 17, which is used as a maintenance platform for the staff. The working platform 17 is located on the right side of the inlet and outlet 5 on the support plate 4.

[0025] Working principle: By starting the motor A7, the screw rod 8 starts to rotate. Since the screw rod 8 is rotationally connected to the side surface of the moving frame 9, when the screw rod 8 rotates, the moving frame 9 will move along the length direction of the screw rod 8. The moving direction of the moving frame 9 is determined by the rotation direction of the screw rod 8, thereby driving the motor B10 fixed on the rear surface of the moving frame 9 and the wire-taking wheel 11 and the working platform 17 connected thereto to move together. When it is necessary to adjust the angle at which the working platform 17 fits the inner wall of the chimney 1, start the motor C13, and the output end of the motor C13 drives the rotating shaft 14 to rotate, and the gear 15 fixed on the side surface of the rotating shaft 14 rotates accordingly. Since the gear 15 is meshed with the gear ring 16, when the gear 15 rotates, the gear ring 16 and the turntable 3 connected thereto will rotate, and the rotation of the turntable 3 The support plate 4 and the mounting frame 6, motor A7, screw rod 8, mobile frame 9, motor B10, take-up wheel 11 and rope 12 installed thereon are driven to rotate together. Since the working platform 17 is connected to the take-up wheel 11 through the rope 12, when the turntable 3 rotates, the working platform 17 will also change the fitting angle with the inner wall of the chimney 1 accordingly. When it is necessary to move the working platform 17 to the outside of the chimney 1, start the motor B10 to rotate the take-up wheel 11, shrink the rope 12, and the working platform 17 will rise to the inlet and outlet 5. The screw rod 8 is rotated by controlling the motor A7, thereby driving the mobile frame 9 and the motor B10, the take-up wheel 11 and the working platform 17 thereon to move to the outside of the inlet and outlet 5, so as to prevent the working platform 17 from being corroded by harmful gases or high temperature during the operation of the chimney 1.
