A driving component for driving the two groups of screw rods 13 to rotate synchronously is installed on the base 1, and a plurality of rollers 8 are installed at the bottom of the base 1.

[0030] When in use, the inspection platform is moved to a suitable position through the movable plate 8, and then the two sets of screw rods 13 are driven to rotate synchronously through the driving assembly. When the screw rods 13 rotate, the nut block 11 will be driven to move toward the ladder plate 2. At this time, the pushing plate 10 will push its corresponding hinged plate 16 to rotate. Since the adjacent ladder plates 2 are hinged with hinged plates 16, several ladder plates 2 will be unfolded under the action of the hinged plates 16. People can step on the ladder plates 2 to climb up to inspect the maintenance area of the photovoltaic power station.

When the transmission tube 5 rotates, it will drive the two-way worm 14 to rotate. Since the worm wheel 12 is engaged with the two-way worm 14, the two sets of lead screws 13 are driven to rotate synchronously. The self-locking properties of the two-way worm 14 and the worm wheel 12 and the lead screw 13 can prevent the unfolded ladder plate 2 from being retracted. When the handwheel 26 is released, the protruding handwheel 26 can be easily retracted into the storage port 9 under the action of the spring 4 to prevent the walking staff from hitting the handwheel 26.

At this time, the spring 4 will be stretched. Then the operator can turn the hand wheel 26 to drive the transmission tube 5 to rotate. When the transmission tube 5 rotates, it will drive the two-way worm 14 to rotate. Since the worm wheel 12 is engaged with the two-way worm 14, it will drive the two sets of screws 13 to rotate synchronously. When the screw 13 rotates, it will drive the nut block 11 to move toward the ladder plate 2. At this time, the push plate 10 will push its corresponding hinged plate 16 to rotate. Since the adjacent ladder plates 2 are hinged with hinged joints, the two sets of screws 13 will rotate synchronously. Plate 16, at this time, under the action of the hinged plate 16, several ladder plates 2 will be unfolded, and personnel can step on the ladder plates 2 to climb up to the maintenance area of the photovoltaic power station for inspection. After the inspection is completed, the drive assembly can retract several ladder plates 2, thereby reducing the volume and making it easier for personnel to carry the equipment. The self-locking properties of the bidirectional worm 14 and the worm wheel 12 and the self-locking properties of the lead screw 13 can prevent the unfolded ladder plates 2 from being retracted. When the hand wheel 26 is released, the protruding hand wheel 26 can be easily retracted into the storage opening 9 under the action of the spring 4, preventing the walking staff from hitting the hand wheel 26;

[0040] After the hand wheel 26 is retracted, the first positioning tooth block and the second positioning tooth block will be closed, thereby improving the self-locking property of the device;
