Description

The invention relates to mobile scaffolding for construction work, which is transported on rails near an erection and has racks of metal pipes. Similar scaffolding is proposed to be supplied with two poles consisting of each of two. fixed pipes connected by crossbars and a riser pipe located between them, which, firstly, has two longitudinal gear racks for coupling with the gear wheels lifting it, rotated cables with the help of winches, and secondly, the rail that serves for a raised working platform, and keeping the pipe in a raised position is meant to be carried out with a dog on the console.

In FIG. 1 is a perspective view of mobile forests; FIG. 2 - 8 - details of the device of the lower part of the scaffolding and the riser; FIG. 9 is a top view of the working platform and gear system; Fig. 10 shows the scaffolding from the side of the building; Fig Pi 12 is a view of the forest from the side and from the front; FIG. 13 and 14 - parts telescopically sliding struts.

For the installation of mobile scaffolding along a building or building, flooring is made of several planks 1 (Figs. 1 and 11). Along each board laid

and reinforced straight four-sided strips (rails) with, on which a platform forms the basis of mobile forests, consisting of several (by the number of rails) beams (wooden or metal), fastened together in rectangle 2-3-4 5 through the transverse bars 2-3 and 4-5 and in the middle of the fastened straps 6-7 (Fig. 1 and 9). This platform is mounted on movable bars with wheels 1 having a wide rim with a recess in the middle, which is placed on rails with (Fig. 2). Bar g with wheel 6 can move up and down and at the desired height it is fixed to square plate e, which in turn is firmly and fixedly mounted on the girder beam and supported by the stop / (fig. 3). To simplify the installation of the platform at the required height, you can make the bar g round, with a screw thread, and pass that through the beam. In this way, each row of wheels can be lowered below, for example, if the do13og and trojyap where the work is done are not located at the same level (Fig. 11). The platform on wheels can move freely along rails along the building. Extending flooring with forests can move forests along the entire building. In addition, since the wheels can rotate exactly. ,, - "--7 - -:. .v, ....-. “,

meb (fig. 3) around its vertical axis, then, therefore, the movement of forests

I on the rails are nailing not only in a straight line, but also at an angle. On beam 8-9. 1 and 9) six cylindrical protrusions 40 (Figs. 1, 4, 5 and 10) are made, with each being fixed on the platform by means of a horizontal axis 41, thanks to which the projections can be inclined. On the sides (Figures 4 and 5) . Two pairs of pillars 10, 10 and two lifting pipes 13 are put on these protrusions (Figs. 1.9 and 10). The metal tubes of the trucks 10, 10 are connected between themselves 1 pairs of pairs of cross-pieces 11a, 11 and are fixed on the platform with fixed struts 12 (Fig. 1). The cross-pieces Pa {fig. 9) consists of two parts, between which a smooth rail 136 passes, located on the riser 13. Both parts of the crossbars 11e are fixed to the uprights 10, 10 by squares 42 (Fig. 1). (Lopereins 116 are one-piece, attached on the other side of the pillars on the hinges. And therefore, one end can be folded to the side, where endless chains are removed, with parts of the gear wheels on which they are worn (Fig. 9). In the space between the crossmembers 11a, 116 and pillars 10, 10, the lifting tubes 13 pass, along the entire length I of which two gear racks 1 are located on the sides, and between these rails the rail 136 is turned upwards to the building. The pipes 13 are raised upwards by means of a gear and chain system. gear f4-15- 16 and 17 (Figs. 1 and 9), and gears 14a, 15a, 16b 17a (Fig. 9), which engage with the rails 13a, serve to lift the movable tubes 13. The gear wheel 14b is connected endlessly, chains 9 to the winch 2p. , and a gear wheel by a winch 21, (Fig. 1). Ordinary wheels 18 (Fig. 1) on the furrows in the middle of the rims, which include the toothed rails 13a, serve only for the correct vertical direction of the racks

In relation to the platform. Fortified on racks 10.10 consoles 19 (Fig. 1)

“And at their ends, which fit to the pipe 13, are named on the hinges of the pawl, holding the pipes 13 from being lowered 1; 1 downwards. FIG. 8 depicts three positions, in kotyur there may be dogs.

The cable or rope 24, thrown over the blocks 22 and wound onto the shaft by a winch 25 (Fig. 1) lifts reinforced on it. the end, which is branched into four parts, is box 26 with two platforms 27 and 28, which, having cutouts in their middle, are put on box 26 and, resting on the treads made at its bottom, are lifted on the rope along with the box. The four indicated branches of the rope have rings at their ends, and on the walls of the crate there are hooks on which rings are put on. Thus, the clerk can always be unhooked from the rope. On none of the platform 28, on the side facing the racks, there are two pairs of wheels 31 and 32 (Fig. 9). The wheels 31 have depressions on the rim that correspond in size to the width of the D110 rail 136 on the riser 13. When lifting, the platform 28 by the wheels 31 slides over the smooth rail 136 and thus the drawer entering the slot of the board does not swing, but smoothly rises up. The wheels 32 also serve as guides, but only when the pipes 13 are raised very high (Fig. 12), and therefore, when the wheels 31 are empty, then they are replaced by ko: scaffolding 32, giving, the platform with direction along fixed stands 10, 10. The work platform 27, represented by a large platform (properly enclosed for safety), on which they must find, with workers during operation, rises up along with the lower platform 28 and the cradle 26 (Fig. 1.0). at a certain height, the worker lifted together with the clerk secures the platform, 27 hooks 29 and brackets 30 to the teeth of the pipe 13. The box and platform 28 are lowered down, and the worker remains at the top of the working platform 27. With the next ascent, the crate delivers the working tool, material for work, and if necessary, also workers. In the same case, when the work is finished, the worker himself goes down. The box is equipped with wheels 43 (Fig. 9), which, when lowered, becomes directly onto the rails. Hop into the rings of branches of the rope from the hooks of the box, the worker pulls the box along the rails to the side for loading, and another similar box, already loaded (Fig. 1), rolls up to the place where the lift starts up. Thus, the drawers can be alternately loaded directly from the wagon. When work is finished at this height, pipes 13 are raised higher by means of winches 20 and 21, and if pipes 13 are used entirely (Fig. 10), extensions are made with additional parts 33, of which there may be several, depending on the height of the building. All Cheni have, as well as the main pipe 13, two toothed racks on the sides and one.-Smooth in the middle. The upper end of the additional part is somewhat thinner and enters the lower end of the upper pipe and is then fastened with screws. Thus, the pipe 13 can be extended to its desired height. To stabilize the scaffolding, pipes 10, 10 are fastened with struts 12 and 36 (Fig. 11), and the working platform 27, raised up, is supported by fixedly sliding bars 38. To maintain the lower platform 28 at such a height that the platform does not interfere with the movement of the lowered on the rails of the box, serves as a support 39 (Fig. 11). For stability of the working platform 27, supports 34 are installed at a high height (Fig. 11), "which are arranged from two struts, with one 34a entering the inside of the other 346. The inner side of the brace 346 is divided along the four strips; There are ratchet teeth along two opposite bands, and the end of the strut 34a (Figs. 13 and 14) is provided with spring dogs, which are pushed to the sides by prugs and thus allow the strut 34a to go deeper into the strut 34i. The other two lanes inside the tidy 346 (of course also opposed to one another) {have cuttings, but in the opposite direction than the first ones, and if you turn one of the struts of the support around its axis 90 °, then the plates Those located at the end of the strut 34a cease to operateTBOBaTb, and the strut 34a slides freely into the strut 346; thus, it is very convenient to operate with such a support at any height. When lifting. The pipes 13, by means of the winches 20 and 21, the pods 34 themselves move apart and are set in place when lifting stops. When lowering the pipe 13

it is necessary to separate the lower end of the struts from the platform and rotate it by 90 °, at which the struts will slide one part into another and shorten. When using the entire length of both parts of the strut, you can enter a third nast, similar to the strut 34o, but only from the other-lower-end of the strut 346. It is necessary to make all racks with a platform collapsible so that there are no difficulties when transporting forests from one place to another. The proposed movable forests can be used both for construction and repair work, and for lifting rails to the upper floors of buildings.

The subject of the patent.
