[0035] Working principle: When it is necessary to repair or maintain the pulse machine or its internal components on the pulse box 14 above the dust collection box 12, the user can first place the required repair tools on the storage box 42, and then use the safety buckle 51 to strengthen the connection between the user and the fixed ladder 3. Subsequently, the user can climb the fixed ladder 3. During the climbing process, since the safety buckle 51 is fixedly connected to the sliding seat 52 through the safety rope 512, and the sliding seat 52 and the central seat 54 are fixedly connected through the L-shaped rod 53, the central seat 54 and the sliding seat 52 can slide upward on the fixed ladder 3 together with the user. Also, since the two ends of the second connecting shaft 67 rotatably provided inside the central seat 54 are respectively fixed with a transmission gear 68 and a worm 69, wherein the transmission gear 68 meshes with the rack 62 fixed to the bottom surface of the maintenance platform 2, the worm 69 is meshed and drivingly connected with a worm gear 610 rotatably connected to the central seat 54 by means of a bearing 611, and the worm gear 610 is slidably connected with a square rod 63 passing through the central seat 54, and the first connecting shaft 66 fixedly connected with the square rod 63 is drivingly connected with the main differential gear 64 through a pulley group 61, and the main differential gear 64 meshes with a sub-differential gear 65 fixed to the screw rod 45. Therefore, when the central seat 54 slides upward with the user, through the transmission of structures such as the rack 62, the transmission gear 68, the second connecting shaft 67, the worm 69, the worm gear 610, the square rod 63, the pulley group 61, the main differential gear 64, and the sub-differential gear 65 in sequence, the screw rod 45 rotates together. The connecting seat 46 threadedly connected with the screw rod 45 is fixed to the sliding plate 43, and the sliding plate 43 is also provided on the guide rail 41 fixedly connected with the maintenance platform 2 in a sliding connection manner. After the screw rod 45 rotates, it can drive the sliding plate 43 and the storage box 42 placed on the sliding plate 43 and carrying the maintenance tools to slide upward together. Therefore, after the user climbs onto the dust collector 1, the storage box 42 synchronously carries the tools and climbs onto the table surface of the dust collector 1; a hydraulic push-pull rod 57 is also provided on the guard plate 56 fixed to the bottom surface of the maintenance platform 2, and the output end of the hydraulic push-pull rod 57 is fixed with a fixing plate 55.
