Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

In the description of the present invention, it is to be understood that the terms "front", "back", "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

As shown in fig. 1-3, this embodiment discloses a movable scaffold frame applied to main structure of open cut section, and it mainly includes scaffold frame body 1, five walking beam 2 and draw gear, and scaffold frame body 1 is the dish knot formula full hall scaffold frame that constitutes by horizontal pole, montant, diagonal draw bar and shear force support. The five walking wheel longitudinal beams 2 are arranged at the bottom of the scaffold body 1 in a left-right parallel mode, a plurality of phi 48 steel pipes are welded on the top surface of each walking wheel longitudinal beam 2 along the front-back direction, and the top end of each steel pipe extends to the top of the scaffold body 1 and is fixedly connected with the cross position of the cross rod of the scaffold body 1 through a fastener. A plurality of walking wheels 3 are installed at the bottom of each walking wheel longitudinal beam 2 along the front-back direction, and the corresponding walking wheels 3 can be rotatably installed at the bottom of each walking wheel longitudinal beam 2 through welding a left wing plate 7 and a right wing plate 7 and through a bearing assembly in order to facilitate assembly.

But install a plurality of height-adjusting's collet subassembly 4 in scaffold body 1's bottom, every collet subassembly 4 includes bottom plate board and lead screw, with the lead screw vertical to fixing on the top of bottom plate board, the rotatory knot that can upper and lower swivelling movement is installed to intermediate position screw thread on the lead screw, correspond threaded connection in scaffold body 1's montant lower extreme inner skleeve with the lead screw at the rotatory upper segment pole of detaining, adjust lead screw earlier and reach suitable position, then adjust rotatory the knot, the lower extreme at the montant is supported to the top surface that makes rotatory knot, realize fixing.
