when the movable platform 8 is lifted, the pressing plate 18 can be pulled through the pressing rod 17, so that the pressing plate 18 moves upwards in the pressing cylinder 19, water in the water tank 22 is pumped through the communicating pipe 21, and the water enters the pressing cylinder 19; when the movable platform 8 is lowered, the pressing plate 18 can be pushed by the pressing rod 17, so that the pressing plate 18 moves downwards in the pressing cylinder 19, water in the pressing cylinder 19 can be uniformly sprayed out of the spraying pipe 20 and sprayed around the bracket, and the functions of dust fall, cooling, humidification and the like are achieved, so that the movable platform is suitable for civil construction environments;
the whole bracket is convenient to move and is convenient to transfer to different construction positions by the moving wheel 33; when the movable platform 8 is lifted, the guard plate 38 is gradually lowered, and meanwhile, the guard plate 38 is gradually lowered, the inserting rod 42 is driven to move downwards through the bottom rod 41, the inserting rod 42 moves downwards so as to be inserted into the ground, the position of the whole support is stably fixed, movement is prevented when the movable platform is used, and stability and safety are better;
specifically, when the lifting plate 7 drives the movable platform 8 to lift, the driving wheel 36 meshed with the outer wall of the lifting plate is driven to rotate, the driving wheel 36 rotates to enable the guard plate 38 meshed with the outer wall of the lifting plate to gradually move downwards, the guard plate 38 gradually moves downwards through the bottom rod 41 to drive the inserting rod 42 to move downwards, the inserting rod 42 is inserted into the ground, and the position of the whole bracket is stably fixed;
when the nut 4 drives the jacking plate 7 to move upwards through the connecting rod 5, the supporting rod 31 is driven to move upwards, the supporting rod 31 moves upwards to a certain position to support the supporting plate 30, the supporting plate 30 moves upwards to drive the movable plug 26 through the vertical rod 28, the movable plug 26 moves upwards to compress the spring 29, and meanwhile, air is introduced from the sucker 25 through the air pipe 24, at the moment, if the sucker 25 covers a wall, the movable plug 26 moves upwards to enable the sucker 25 to generate negative pressure, so that the sucker 25 is firmly adsorbed on the wall, and the position of the whole bracket is stably fixed.
