[0028] Working principle:
[0029] When the device is in use, the device is moved to a specified position through the moving base 1, the device driving housing 2 is rotated to adjust the orientation of the device, and further, each support curved arm 3 is controlled by a hydraulic device to rotate around the steering base 4 to open and close, so that each support curved arm 3 can form a certain shape, driving the platform support base 5 and the platform chassis 6 to move to a high working position. Before working, the platform chassis 6 stays on the ground. Further, the latch 20 is opened to open the opening and closing door 14. The staff enters the lifting platform through the gap 8 and the vertical rods 9 provided on both upper sides. Subsequently, the latch 20 is connected to close the opening and closing door 14. A number of the vertical rods 9, the first surrounding rod 10, the second surrounding rod 11, etc. are provided on the upper part of the platform chassis 6 to form a fence to protect the staff. The upper part of the second surrounding rod 11 is fixedly provided with a fence track 12, so that the track 18 fixedly provided on the upper part of the opening and closing door 14 is connected to the fence track 12 to form a closed track with a smooth corner. A console 21 is provided on the upper parts of the fence track 12 and the track 18. A number of track wheels 28 are provided on both lower sides of the console 21. The track wheels 28 are connected to the fence track 12 and the track 18. Through the track wheels 28, the console 21 can be fixed on the fence track 12 and the track 18 and can slide. When the position of the console 21 needs to be changed, the console 21 is pushed to move on the fence track 12 and the track 18 through the second handle 32. When the console 21 needs to be moved to different directions, since the track wheels 28 are connected to the rotating seat 22, the console 21 is rotated through the rotating seat 22. And a slidable sliding rod 25 is provided inside the rotating seat 22, and a rotatable rotating shaft seat 27 is installed at the lower part of the sliding rod 25 and connected to the track wheels 28. When the track wheels 28 can be rotated to different directions, the sliding rod 25 is displaced through the rotating seat 22 and the sliding rod 25, so that the two track wheels 28 are always in contact with the fence track 12 and the track 18 and turn to different direction positions. Further, springs 29 are provided on both sides of the sliding rod 25. Through the two springs 29, the sliding rod 25 returns to the initial position after the console 21 turns, so that the console 21 is kept balanced. By moving the console 21 to different directions, the staff can always face the observation direction when controlling the device, ensuring the safety during the control process, and can operate simultaneously when working in different positions, increasing the use scenarios of the device and enhancing the flexibility of the device.
