Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-4. The utility model provides a technical solution: an adjustable mobile scaffold for construction, comprising:

Two sets of first frames 100, the first frames 100 include a supporting beam 101, and hollow columns 104 are welded at both ends of the lower surface of the supporting beam 101;

The two sets of second frames 200 include extension columns 201 slidably inserted into the inner cavities of the two sets of hollow columns 104. The two hollow columns 104 constituting the same second frame 200 are provided with guide grooves 105 connected to the inner cavities of the hollow columns 104 on opposite sides. The two ends of the first fixing rod 202 are slidably installed in the guide grooves 105 of the two hollow columns 104, and the two ends of the first fixing rod 202 are respectively connected to the two extension columns inserted in the hollow columns 104. The columns 201 are fixedly connected, and a second fixing rod is fixed to the bottom of the two extended columns 201 and on one end extending out of the hollow column 104. Multiple groups of second locking holes 203 are provided on the outer sides of the two groups of extended columns 201. The lower ends of the outer sides of the two groups of hollow columns 104 are plugged with second locking bolts 106 threadedly connected to the second locking holes 203. The end of the second locking bolt 106 is inserted into the second locking hole 203 to lock the relative position of the extended column 201 and the hollow column 104.

It also includes two groups of connecting frames 300, and the two groups of connecting frames 300 include pedals 301. Both ends of the lower surface of the pedals 301 are welded with clamping plates 302. The opposite sides of the two groups of clamping plates 302 are provided with first locking holes 303. The upper surface of the supporting beam 101 is provided with a clamping slot 102 for the clamping plates 302 to be inserted. Two groups of first locking bolts 103 are symmetrically inserted on one side of the supporting beam 101, and the two groups of first locking bolts 103 are threadedly connected to the first locking holes 303. The first locking bolts 103 are screwed into the first locking holes 303, thereby improving the stability of the pedals 301 embedded in the clamping slots 102 and improving the overall strength of the scaffolding after assembly.

A first clamp 107 is fixedly connected to the middle part of the outer side of the two groups of hollow columns 104, and a second clamp 304 is symmetrically welded to the lower surface of the pedal 301. Both the first clamp 107 and the second clamp 304 are detachably connected to a stabilizing inclined beam 500. The stabilizing inclined beam 500 improves the stability of the connection between the first bracket and the connecting frame 300, and improves the stability of the construction personnel moving on the connecting frame 300.

Two groups of vertical poles 205 are welded on opposite sides of the first and second fixed rods, and two groups of horizontal poles 206 are symmetrically welded on opposite sides of the two groups of vertical poles 205. The lower ends of the two groups of extended columns 201 are fixedly connected to support foot pads 204. The two groups of vertical poles 205 and the two groups of horizontal poles 206 improve the overall stability of the second frame 200, thereby improving the service life of the second frame 200 and avoiding deformation of the second frame 200.

It also includes a moving component 400, which includes an adjusting screw 402 and an adjusting beam 401. A guide rail 404 is provided on the opposite side of the two vertical rods 205 and between the second fixed rod and its adjacent cross rod 206. Both ends of the adjusting beam 401 are slidably connected in the guide rail 404, and the adjusting beam 401 is driven by a driving mechanism to move up and down along the guide rail 404. Both ends of the bottom surface of the adjusting beam 401 are respectively fixed with a vertically arranged plug rod 405, and the second fixed rod is provided with a through hole matching the size of the plug rod 405. The plug rod 405 is slidably installed in the through hole, and the bottom end of the plug rod 405 passes through the second fixed rod and a moving wheel 406 is fixed thereon. The driving mechanism is a screw driving mechanism. The screw drive mechanism includes an adjusting screw 402 rotatably installed between a second fixed rod and an adjacent cross bar 206. The adjusting screw 402 is arranged vertically, and the top of the adjusting screw 402 extends out of the cross bar 206, on which a hand wheel 403 is fixed for facilitating the rotation of the adjusting screw 402. The adjusting screw 402 is threadedly connected to the adjusting beam 401. The adjusting screw 402 is threadedly connected to the adjusting beam 401, thereby driving the insertion rod 405 to move up and down, making it convenient for the moving wheel 406 to contact the ground and move the entire scaffold, thereby reducing the labor intensity of construction workers in carrying the scaffold. By rotating the hand wheel 403, the adjusting screw 402 is driven to facilitate the height adjustment of the moving wheel 406. The operation is simple, and the stability of the lifting and lowering of the adjusting beam 401 is improved through the guide rail 404.

When in use, firstly, the two ends of the two groups of connecting frames 300 are clamped with the supporting beams 101 of the two groups of first frames 100, and then the supporting beams 101 and the clamping plates 302 are fixed by the first locking bolts 103, so as to improve the stability of the connection between the first frame 100 and the connecting frame 300, and the two ends of the stabilizing inclined beam 500 are respectively clamped with the first clamping piece 107 and the second clamping piece 304, so as to improve the stability of the first frame 100 and the connecting frame 300 after installation, and improve the stability of the user standing on the pedal 301. When masonry plastering construction is carried out on stairs or at a location with a high degree of misalignment, the second frame 200 at the lower end of one of the first frames 100 is adjusted so that the second locking bolts 106 are screwed into the corresponding second locking holes 203, so that the extension lengths of the two groups of second frames 200 are different, so as to be suitable for the construction environment of stairs and high-level misalignment, improve the application range of the scaffolding, and improve the safety factor of the construction personnel standing on the pedal 301.
