[0036] Please refer to Figures 1 to 4 The self-walking aerial work platform comprises a main platform 1, a supporting wheel 2, a closed slide 3, a rear guide wheel 4, a sliding platform 5, a front guide wheel 6, a limiting roller 7 and a sliding assembly. The supporting wheel 2 is provided with two supporting wheels 2, and the two supporting wheels 2 are rotatably arranged on the main platform 1. Two rotating openings are symmetrically formed in the main platform 1, and the two supporting wheels 2 are rotatably arranged in the two rotating openings, so as to facilitate the stable sliding of the supporting wheel 2 on the main platform 1, and facilitate the stable lifting of the sliding platform 5. The closed slide 3 is provided with two closed slides 3, and the two closed slides 3 are symmetrically connected to the two sides of the main platform 1. The closed slide 3 can be in the shape of a square tube in actual production, or can be in the shape of a bent metal plate. The shape of the bent metal plate can reduce the production cost. The rear guide wheel 4 is provided with two rear guide wheels 4, and the two rear guide wheels 4 are rotatably installed on the two closed slides 3. The sliding platform 5 is slidably arranged on one side of the main platform 1. The front guide wheel 6 is provided with two front guide wheels 6, and the two front guide wheels 6 are symmetrically rotatably arranged on the two sides of the sliding platform 5. The limiting roller 7 is rotatably installed on the upper side of each front guide wheel 6, and can limit the sliding platform 5 to a certain height. Through the cooperation of the limiting roller 7 and the supporting wheel 2, the sinking of the sliding platform 5 can be prevented. At the same time, bearings are installed in the supporting wheels 2 of the main platform 1, so that the sliding platform 5 can be easily slid even if the weight in the sliding platform 5 is 150-200KG. The sliding assembly is arranged on the sliding platform 5. The sliding platform 5 is symmetrically connected with two sliding guardrails 14, and the two sliding guardrails 14 are connected with a protective frame 15, so as to facilitate the protection range of the sliding platform 5, and can protect the staff on the sliding platform 5 in all directions.

[0037] Specifically, the sliding assembly comprises a limiting cylinder 8, a sliding roller 9 and a supporting roller 10. The limiting cylinder 8 is provided with two limiting cylinders 8, and the two limiting cylinders 8 are symmetrically connected to the sliding platform 5. The two limiting cylinders 8 are slidably arranged in the two closed slides 3. The sliding roller 9 is rotatably arranged on one side of each limiting cylinder 8. The supporting roller 10 is provided with two supporting rollers 10, and the two supporting rollers 10 are rotatably installed on each limiting cylinder 8. The limiting cylinder 8 is provided with a supporting opening for the rotation of the supporting roller 10.

[0038] Through the rotating cooperation of the two sliding rollers 9 and the four supporting rollers 10, the two limiting cylinders 8 can slide in the two closed slides 3 respectively, and the sliding platform 5 can slide stably on the main platform 1, and the limiting cylinder 8 and the closed slide 3 can form full enclosure, the sliding platform 5 rollers are not exposed outside, and it can be ensured that the garbage such as stones, bricks, screws and branches cannot affect the rotation of the sliding platform 5 rollers.
