[0027] Working principle:

[0028] When in use, firstly, the lifting frame can be easily moved in the workplace through the four universal wheels 21. When the lifting frame needs to be fixed in position for lifting operations, it can be locked by the brake device set on the four universal wheels 21 to prevent movement during the lifting process. When the lifting platform 4 needs to be lifted, the motor 16 in the driving member is started. The output shaft of the motor 16 is connected to the threaded rod 13, so when the motor 16 rotates, the threaded rod 13 will also rotate. Since the connecting block 14 is fixedly installed on the outer wall of the support column 9 above the first cross arm 2, and the support column 9 and the connecting block 14 are threadedly connected to the threaded rod 13, the rotation of the threaded rod 13 will drive the connecting block 14 and the support column 9 connected thereto to move up and down along the threaded rod 13. This movement further drives the up and down movement of the second cross arm 3 through the support column 9. Since the second cross arm 3 is connected to the lifting platform 4 through the support column 9, the lifting function of the lifting platform 4 is finally realized. At the same time, the limit groove 15 on the bottom surface of the lifting platform 4 limits the connecting block 14 to ensure that the connecting block 14 will not deviate during the movement, thereby ensuring the stability of the lifting. On the lifting platform 4, the setting of the protective component plays an important safety protection role. The protective plate 5 is fixedly installed on the top surface of the lifting platform 4, providing a basic working platform for the staff, and the guardrail 6 is connected to the protective plate 5 through four electric push rods 7. When the height of the guardrail 6 needs to be adjusted to accommodate staff of different heights, the electric push rod 7 is operated by the controller 8 to extend and retract its output shaft, thereby driving the guardrail 6 to extend and retract synchronously. This design can ensure Regardless of the height of the staff, the guardrail 6 can provide effective protection to prevent the staff from falling during the lifting process. The controller 8 is the control center of the entire lifting frame. It is connected to the motor 16 and the electric push rod 7 through the circuit. The operator can control the start and stop of the motor 16 and the extension and retraction of the electric push rod 7 through the button 20 on the controller 8, so as to achieve the lifting of the lifting platform 4 and the height adjustment of the guardrail 6. The display screen 19 on the controller 8 can display the current height of the lifting platform 4, the operating status of the motor 16, and the extension and retraction status of the electric push rod 7 in real time, so that the operator can monitor and adjust the working status of the lifting frame in real time. In addition, a storage box 17 is fixedly installed on the top surface of the lifting platform 4 for storing tools and materials, so that the staff can use them at any time when performing decoration work on the lifting platform 4. In summary, the decoration lifting frame realizes the smooth lifting and effective protection of the lifting platform 4 through unique lifting components, protective components and control devices, and provides a safe and efficient lifting tool for the field of building decoration.
