    The invention relates to movable folding scaffoldings designed to accommodate people and equipment at various levels underground or under the base of a room.
    Folding scaffolding is known, the telescope contains 1 stanchions with braces and a working floor, with ethane each diagonally jointed yen at one end to the rack and the other to the movable VO rack clutch, and the flooring is made of sections 111 that are hinge joining each other,
    The disadvantage of these scaffoldings is the need for flooring in front of the scaffolding storage and the absence of elements that facilitate their movement, which complicates their operation.
    Known as well are movable folding scaffoldings containing working deck sections, a hinge for connecting sections, made with the ability to pivot sections of bottom surfaces towards each other, zeitral supports and side supports that are hingedly attached to sections of the deck, made with support rollers. at the ends and soiedii
    with hinge rods with central uprights G2.
    However, the scaffolds do not provide the possibility of adjusting the height of the working sheet and reliable fixing of the racks in the working position of the scaffold. Closest to the invention are movable folding scaffolds containing working deck sections, hinges for connecting sections, made with the possibility of rotating sections by lower surfaces to each other, central support legs attached to the floor section hinges, side support legs hinged to the sections flooring and performance with support rollers at the ends, and ti hinges that are hinged at one end to the side support pillars and at the other end to the bottom surfaces of adjacent sections of the Gz7 flooring.
    The lack of scaffolding is due to the fact that they do not provide the possibility of adjusting the height of the working deck, which reduces the convenience of their operation.
    The purpose of the invention is to increase the satisfaction of exploitation under ustey.
    The goal is achieved by the fact that in movable folding scaffoldings containing sections of the working flooring, hinges for connecting sections made with the possibility of rotating sections by lower surfaces to each other, central support posts attached to the section hinges come, lateral support posts, hinged attached to the sections of the flooring and made with support rollers at the ends and ti gi pivotally attached with one end to the side support pillars and the other ends to the lower surfaces of the adjacent sections of the flooring support telescopic and provided with braces, the lower ends of which are hingedly attached to the lower sliding parts of the uprights, and the upper ends connected to the rods by means of sliding couplings with friction locking devices. In addition, the support rollers are attached to the uprights by means of swivel brackets and equipped with mounting devices. them in the working and non-working positions, made in the form of lever mechanisms connected to the brackets with power handles. To ensure that the scaffolding is locked in the working position, the hinges of the deck sections are made with a locking device. In order to prevent the possibility of connecting the scaffolding with other scaffolds before fixing the working position, the locking device is equipped with a driving handle protruding beyond the scaffold at the level of the flooring with the inoperative position of the locking device.

    [1]
    To adjust the height of the scaffolds, the central support posts 16 contain telescopically extending parts 36, and the side support posts 12 and 13 respectively have moving parts .37 and 38. For fixing the posts, pins 39 are installed in holes 40, made at certain intervals along nominated parts of racks. At the ends of the uprights, new slotrs 41 are installed. The rigs 22 and 23 are made with adjustable stabilizing struts 42 and 43, the lower ends of which are attached by means of hinges 44. to the retractable parts 37 and 38 of the uprights 12 and 13, and the upper ends are connected to the slides Each clamping sleeve 4.5 consists of a tubular element 46, a lining 47 welded to it, and a friction screw 48 installed in a threaded hole formed in the element 46 and a strap 47. To the tubular element 46 welded sharni The hinges 48, by means of which both the bolt or rivet 49, the clutch is attached to the flattened end of the diagonal 42 or 43. Vertical braces 51 are welded to the transverse link 50 that connects: the parts of the uprights 12 and 13 are welded. in bushings 53 attached to the upper ends of the f acnopoK 51. The control lever .54 with the drive arm 55 is attached to the rod 52 at either end. A pair of curved brackets 56 at one end is welded to the sleeve 57, which is rotatably mounted relative to the cross link 50, the other ends of the brackets are connected by a plate 58 ,. to which the support rollers 59 are attached. A pair of hinge loops 60 is welded to the rod 52, with loops by means of hinges 61 connecting a connecting rod 62, which is also connected by hinges 63 to the brackets 56. At the bend points, a stitch 64 is welded to the brackets. 6, a bracket 65 is welded with a sleeve 66 at one end and a hinge loop 67 near its other end. In the sleeve 66 with the possibility of axial movement / removal of the shaft 68, having a curved end 69 and a branch 70, the other end of the shaft is connected by a hinge 71 to a pair of t 72, which by a hinge 73 is connected to another pair of t 74, in turn by a hinge 75 , connected to the bracket 65. C t and c 74 attached to the arm 76. The shaft 68 passes through the hole 77 in the plate 10, and the curved end of the G9 and the branch 70 enter the g into the aligned holes 78 and 79, respectively, made in the plates 10. Operation scaffolding is carried out as follows. To transfer the scaffolding from the folded to the horizontal working position, the support rollers 59 are first lowered into their working position. For this, the handle 55 is moved downwards, as a result of which the rod 52 and the hinge loops 60 welded to it are rotated, while the pull 62 pulls the rollers 59 downwards. When the hinges 60 are rotated, the hinges 61 move up to the stop in the pad 64, in which the rollers 59 stop in the lower position. After that, the scaffolding is disassembled, the sharp movement of which to the sides is prevented by the rods 28 working on twisting when the pillars 12 and 13 are rotated. After the scaffolding is unfolded, they are fixed in the working position. To do this, the handle 76 is moved downwards, as a result of which the thrusts 74 and 72 move the shaft 68, while its curved end 69 and branch 70 enter respectively into the aligned holes 78 and 79 in the plates 10, fixing sections 1 and 2 of the working flooring in the combined position. Since, with an unlatched position of the scaffolding, the handle 76. extends beyond the scaffold at the level of the working deck, this is a signal that the scaffolding needs to be fixed. In addition, if it is necessary to form a platform with a large working floor by installing several scaffoldings to each other, the protruding arm 76 will prevent the adjoining of other scaffoldings. The scaffoldings fixed by means of rollers 59 are moved to the place of their use, after which the rollers 59 raise and the scaffolding they are supported by racks 12, 13 and 16. To raise the rollers 59, the arm 55 moves upwards, 3 as a result of which the loops 60 turn, which, by means of the strands 62, rotate the brackets 56 upwards from the roll | 1k-; mi 59.. . If it is necessary to increase the height of the scaffolds, the telescopic parts 36-38 of the uprights 12, 13 and 16 are pushed in. Before the height of the uprights 12 and 13 are increased, the friction screws 48 of the couplings 45 are slightly unscrewed. When extending the telescopic parts 37 and 38 of the uprights 12 and 13, the braces 42 and 43 move downwards , while the sleeves 45 freely slide along tam 22 and 23. After adjusting the uprights 12, 13 and 16, they are fixed to the required height with pins 39 installed in the aperture 40, then tighten the friction screws 48 of the sleeves 45 until the stops are locked in 22 and 23, thereby fixing the working position of the brace 42 and 41. After completion of using scaffolds their folded. To do this, slide the telescopic parts into the racks 12, 13 and 16, roll the rollers 59 into working position, move the scaffolding to the storage location, lift up the handle 76 to unlock the scaffolds and turn sections 1 and 2 with the bottom surfaces towards each other. and 2 tons of gigs 22 and 23 rotate the pillars 12 and 13 to the lower surface of sections 1 and 2, while the twisted rods 28 assist in folding the scaffolds and raising sections 1 and 2 upwards. After installing the stacked scaffolding at the storage site, the rollers 59 lift upwards. Claims 1.
