[0034] Thus, when the operator stands on the lifting platform 210, the two arc-shaped plates 420 are pushed in opposite directions, and the operator stands between the two arc-shaped plates 420. Then, the arc-shaped plates 420 are stretched towards the operator until they contact the operator's waist. After contact, the locking rod is tightened, and the arc-shaped plates 420 fix the operator in the middle. The telescopic rod 430 can slide along the second slide groove 470 on the protective plate 410, ensuring that the operator can move back and forth on the lifting platform to meet the flexibility of installing electrical equipment of different sizes, while improving the safety of the operator when installing electrical equipment.

The wire rope 250 pulls the first slider 220 to slide upward in the first slide rail, thereby driving the entire lifting plate 210 to move upward, realizing the movement of the lifting plate 210. After installation, the oil pump 231 is depressurized, the oil cylinder 230 retracts, driving the lifting component 240 to descend, and the lifting plate 210 falls.

[0037] The electrical equipment to be installed is placed on the carrier plate 310. After the lifting plate 210 reaches the designated position, it stops. The cylinder 330 works, pushing the carrier plate 310 up. The carrier plate 310 moves upward along the guide rod 212. After it is raised to the appropriate position, the cylinder 330 stops working. The operator can then install the electrical equipment without having to lift it, reducing the operator's workload and making the installation more convenient.

[0038] When the operator stands on the lifting platform 210, the two arc-shaped plates 420 are pushed in opposite directions to open. The operator stands between the two arc-shaped plates 420 and then pulls the arc-shaped plates 420 towards the operator until they contact the operator's waist. After contact, the locking rod is tightened, and the arc-shaped plates 420 fix the operator in the middle.
