(54) DEVICE FOR DIPPING CONSTRUCTION ELEMENTS

12

articulated links and are equipped with a tension mechanism and a stiffening element connected with them, in this case one end of the retractable sliders with non-iodine guides, and the other end with the tension mechanism. The tensioning mechanism can be made in the form of a counterweight to the rope-block system associated with retractable rails, and the extension mechanism can be in the form of sprockets mounted rotatably on the hydraulic cylinder rod and around the retractable rails. The stiffener element has the form of a rod connected to the hydraulic cylinder rod and installed in fixed guides with the possibility of axial movement, while the rod and the sliding directions are made with grooves and corresponding valleys.

FIG. 1 shows a device for immersing building elements; in fig. 2 - mast with guides, slit; pas figs. 3 - section A-A at the bottom of the mast; in fig. 4 —Bb section along extended guides.

ScTpoftcTBo for immersing the building elements consists of a self-propelled chassis / on which the mast 2 is mounted with a spreader 3 and hydraulic cylinders 4, which carry out working inclinations of the mast. The mast is equipped with fixed guides 5, on which the stiffening element 6 is mounted movably in the axial direction;

The sliding guides 9 at one end are coupled with the fixed guides 5, and the other with the tension mechanism 0, consisting of a counterweight 11 and a rope 12 forming a rope-block system with blocks 13.

The extendable guide envelops the sprockets 14 of the extension mechanism 15 mounted on an axis 16 fixed to the end of the rod 17 of the hydraulic cylinder 18.

At the end of the rod on the same axis 16, the support 19 of the mast 2 is pivotally mounted, which serves to increase the stability of the device when drilling or raising the pile. An assembly 20, such as a pile driver or drilling equipment, is mounted on the rails.

The device works as follows.

When driving the pile or drilling, the working body 20 moves down along the guides 5 of the mast 2. When the working body approaches the lower end of the mast (or in advance), the shafts 17 of the hydraulic cylinder 18 are pushed with the support 19 all the way to the ground. Simultaneously TRIT-TTTT-G

14 with their slide-out guide envelopes 9. The link 7 of the slide-out guides are installed in a straight line, forming a continuation of the fixed guides 2. The stiffening element 6 rigidly connected by a bolt 21 with the stem 17, with its projections enters grooves “0 links 7, linking them and fixed guides 5 in a single unit.

The second end of the sliding guides is constantly tensioned by the tension mechanism 10 and, when the stem 17 is pulled in, lifts the releasing guides into the internal cavity of the mast 2,

hollow

Due to this, the working body can be lowered to the very ground without stopping the working process and without lifting the support when extracting the drill from the well.

At the same time, of course, the driver does not need to keep track of the synchronism of movement of the sliding guides and the working body, since the sliding and fixed guides constitute

single whole.
