Description

The invention relates to a land construction, in particular to the installation of tanks from rollable panels.

The purpose of the invention is to simplify the device, reduce the labor intensity and speed up its installation.

FIG. 1 shows a sliding frame, side view; in fig. 2 - a clamp; in fig. 3-6 - the scheme of operation of the device.

The device for unfolding the panels consists of two clamps 1, combined by means of flexible couplings (cables) 2 into the sliding frame 3. Each clamp consists of two supporting posts 4, a truss 5 and limiting posts 6.

Catch 1 is a metal construction of pipes assembled from two support pillars 4, trusses 5 and restrictive pillars 6. Flexible couplings 2 are located between adjacent support posts 4 and are stockpiled in a loopback way: the first electric winch 7 is the bottom block 8 of the second retainer 9 - the upper unit 10 of the first latch 1 - the lower unit 8 of the first latch 1 - the second electric winch 11 (Fig. 1). The presence of such flexible connections 2 allows changing the span of the sliding frame 3, i.e., changing the mutual arrangement of the clamps 1 and 9 moving along the longitudinal guides 12 of the flat frame 13. The supporting legs 4 of the clamps 1 and 9 consist of top right

the linear part 14 and the lower two-legged in the form of two struts 15 that hold the latches in a vertical position (Fig. 2) Farm 5 tubchi with parallel on themselves, rigidly attached to the upper part of the supporting columns 4. Farm 5 are located so that the longitudinal axis each farm is at the height h hn + Rf, where Lsh is the height of the pattern, R p is the radius of the roll. Restrictive posts 6 are rigidly attached to the truss 5 itself, the upper ends of which are bent and turned into the sliding frame 3 to prevent the roll from jumping out. At the ends of the struts 15, spherical hinges 16 are arranged so as to allow the clamps 1 to move along the longitudinal guides 12 of the flat frame 13.

The assembly of the panel unfolding apparatus is carried out in the following order.

A flat frame 13 with longitudinal guides 12 is laid on the prepared section of the assembly site, the plan dimensions of the flat frame 13 are: width b Ьш - | - 1.0 m, length 1 - | - 21; -г - | - - | - 2.0 m, where Ьш 1 «- width and length of the template 17, 1„ - step of the struts.

four electric winchs 7 and 11. Zatuech assemble clamps 1 and 9. For ease of transport, clamps can be divided into three mounting elements (brands), the joints of which are easy to implement with bolts. After the pre-assembly of retainers 1 and 9, they are mounted on a flat frame 13 so that the spherical hinges 16 of the struts 15 fall inside the longitudinal guides

12. Then, the flexible connection of 2 (cables) is made according to the above scheme, the clamps 1 and 9 are joined into the sliding frame 3.

The operation of the device for unrolling the dry goods is carried out as follows (Fig. 3). A template 7 is placed on a flat frame 13 along the longitudinal guides 13. A panel 18 rolled up in a roll is placed in the middle of its arcuate surface, temporarily detaching it from rolling. On both sides of the panel 18, electric clamps 7 and 11 are applied to the clamps 1 and 9 of the sliding frame 3, fixing their position by the tension of the flexible links 2. At the same time, the trusses 5 with the limiting posts 6 are positioned on both sides of the panel, tightly crimping the side panels surface. The cutting strips of the panel 18 are cut off with a cutter. As a result, elastic forces of the self-unfolding panel 18 arise, which, acting on the trusses 5 and the limiting posts 6, try to change the position of the latches 1 and 9, fixed by the tension of the elastic ties 2.

Gradually, the lengths of the flexible couplings 2 are changed (increased) using electric winders 7 and 11, which causes the clamps 1 and 9 to move along the pattern 17 along the longitudinal guides 12 of the flat frame

13. Due to the movement (slow, constant speed of fixers 1 and 9 from the middle of the template 17 to its end sections), the panel 18 is gradually fluffed and unfolded along the arcuate surface of the template 17. After the fixtures 1 and 9 reach the end sections of the template 17 and terminate of the cloth unfolding process, the latches move to the electric winch 7 and 11 at the end of the longitudinal guides 12 and form the end sections of the cloth 18 in a known manner. Then remove the coil of the roll, assemble the element you and rigidity ring 19 temporarily fastened to schablone dissolved panel 17, e.g., via attachment rings 19 ends rigidity to the template setting temporary anchorages in the form of steel strips, and a magnetic suction cup located across the arcuate surface of the template 17.
