Description

1 I

The invention relates to a mounting construction platform with a variable height of the working deck.

The purpose of the invention is to simplify the design and increase ease of operation.

Figure 1 shows the scaffolding with the lower location of the working floor height; figure 2 - the same, with the average location of the working floor ;. fig.Z - the same, with the upper location of the working floor; Figures 4-6. Diagrams of the arrangement of supports and slings with stops when translating the scaffolds from one position to another; in fig. 7 - section A-A in the city; in FIG. 8 - section B-B in FIG. 2; figure 9 is a section bb In fig.Z; figure 10 - scaffolding, axonometric (left half at the upper location of the working floor height); fig. II - telescopic stand; on Fig.12 - section GGD on figure 11 on Fig.13 - section dd on 4ig.11,

The scaffolding consists of the working floor 1 and its attachment to it by means of hinges 2 through telescopic stands 3 of pedestals 4, made in the form of rectangular parallelepipeds. The hinges are mounted on the side face of the support frame, and their axles are mounted on telescopic stands 3,. perpendicular to the axis of the uprights rigidly attached to the working floor I. Those: lescopic posts are provided with limiters 5.

To rotate the pedestals, the 4 platforms are provided with lines 6, one end of each of which is attached to the rod 7 mounted on the side face of the frame of the table 4, and the other end of the lines has a loop 8 and is passed through the holes 9 made in the working floor 1. The lines 6 are equipped adjustable stops 10-12, which can be used, as in this particular case, collet clamps. The number of stops on each line corresponds to the number of positions occupied by the working platform of the scaffold height. The holes 9 in the flooring 1 made slots 13 for the sling. The slits are made in the direction of the center of the flooring. The diameter of the holes is slightly larger than the diameter of the adjustable stops. When placing the slings 6 in the slot x 13 the corresponding stop - collet clamp - its

the end abuts against the lower plane of the working deck. To protect the bottom surface of the flooring from damage in the slotted area (when it is acted upon with an emphasis), the slot is made with a metal edging (not shown). In order to create the transverse stability of the scaffolding, with the upper position of the flooring in the corners of the pedestals 4 and 10, a support bar 14 is fixed. To ensure the relocation of the pedestals 4 from one position to another, the pedestal is equipped with rollers 15.

At the lower height, the position of the working scaffold deck is installed as follows: lines 6 are inserted into slot 13 so that the stop 10 of each line interacts with the flooring. Then the scaffolding raises the load-lifting crane by the loops 8 of the slings 6 (figure 4) and lowers it onto the floor, where the working floor occupies the lower position in height (figure 1).

25 To rearrange the scaffolding from the lower-height position of the working deck to the middle sling 6, the stop 12 interacts with the flooring, then the scaffolding

3Q is lifted by the slings 6. The bollard 4 under its own weight turns around the hinge 2 (FIG. 5), after which the scaffolds are lowered and the working floor resting on the telescopic pillars 3 (located in a folded position) is set to the required average height position (figure 2).

To transfer the scaffolding to the upper height position of the working floor of the sling 6, it is set up in the slot 13 of the flooring 1 so that the lugs of the 1I of the lines 6 interact with the flooring, the lifting device of the scaffolding

lift the lines, thumbs 4 turn 90 around the hinge,. fig. b) and then lower the scaffold of fig. 3) - the working deck is laid down in pedestals 4.

To return the pedestals 4 to the lower position, the stops 11 pull out above the flooring, lift the platforms by means of a lifting crane by the lines 6, the stops 10 interact with the flooring (FIG. 4), lower the work platforms to the floor, the working floor again takes the lower position of the floor (fig.l)
