of the anti-falling frame 9, at this time, the platform 8 can be lowered, so that the platform 8 is not easy to fall.

[0026] The working principle of the high-safety building construction lifting platform is as follows: when the building construction needs to lift the lifting platform to a higher position, the operator stands inside the platform 8, and then starts the motor 11 by operating the control switch group 12; the output shaft of the motor 11 starts to rotate, thereby driving the left screw rod 3 and the left sprocket 4 to rotate; at this time, under the transmission action of the chain 5, the right sprocket 4 drives the right screw rod 3 to rotate synchronously; the left and right ends of the platform 8 are respectively threadedly connected with the screw rod 3; under the thread transmission action generated by the rotation of the screw rod 3, the platform 8 moves upward along the axial direction of the screw rod 3; with the upward movement of the platform 8, the anti-falling frame 9 fixedly connected with the platform 8 also moves upward synchronously; in the process of the upward movement of the platform 8 and the anti-falling frame 9, the anti-falling frame 9 gradually contacts the anti-falling platform 22; with the continuous upward movement of the platform 8, the anti-falling frame 9 extrudes the anti-falling platform 22 upward; under the extrusion action of the anti-falling frame 9, the anti-falling platform 22 rotates along the mounting column 21; at this time, the torsional spring 25 on the mounting column 21 deforms and stores elastic potential energy; when the platform 8 continues to rise and the anti-falling frame 9 leaves the current anti-falling platform 22, the torsional spring 25 releases the elastic potential energy, drives the anti-falling platform 22 to rotate reversely along the mounting column 21, and returns to the initial position; in the process of the anti-falling platform 22 returning to the initial position, the support groove 23 at the lower end of the anti-falling platform 22 is clamped on the support column 24; if the lifting platform accidentally falls at a certain moment after rising, the anti-falling frame 9 will descend together with the platform 8, but since the support groove 23 at the lower end of the anti-falling platform 22 has been clamped on the support column 24, the support column 24 will stably support the anti-falling platform 22; when the anti-falling frame 9 contacts the anti-falling platform 22, the anti-falling platform 22 will block the anti-falling frame 9 from continuing to descend, thereby limiting the descending position of the platform 8, preventing the lifting platform from falling, and providing reliable safety protection for the construction personnel and equipment; when the platform 8 needs to descend, the worker controls the control switch group 12 to drive the two motors 10 to rotate; the output shaft of the motor 10 drives the adjacent horizontal screw rod 7 to rotate; under the thread cooperation of the horizontal screw rod 7, the horizontal screw rod 7 drives the adjacent adjusting plate 27 to slide between the two adjacent upper and lower slide rails 6, thereby driving the mounting column 21 to move backward; the mounting column 21 drives the anti-falling platform 22 to move backward; at this time, the front anti-falling platform 22 moves to the gap in the middle of the anti-falling frame 9, and the rear anti-falling platform 22 moves to the gap at the rear side of the anti-falling frame 9; at this time, the platform 8 can descend.

[0027] It is worth noting that the motor 10 disclosed in the above embodiment can be a stepper motor 42 series, the motor 11 can be a SEW-DRN series, and the control switch group 12 is provided with control buttons corresponding to the motor 10 and the motor 11 and used for controlling the switches of the motor 10 and the motor 11.
