Description

(54) INSTALLATION FOR DIPPING SCREW PILES

., one

The invention relates to the construction and can be used in the construction of bridge piers, power lines, surface racks and t, p. Structures.5

The installation of a few screw pile piles is known, including a platform on which the pile driving mechanisms ij are mounted.

With this installation, the tO piles are screwed down only vertically, with equal torque, which is undesirable due to the different soil composition.

Also known installation for po. 5 loadings of screw piles containing a base machine, on the platform of which a spreader is installed with a crane device carrying the screwing mechanisms with rotary devices 2, 20

The disadvantages of the known installation ARE small mobility and low productivity.

The purpose of the invention is to increase. mobility and performance of 25 installations.

This is achieved by the fact that the installation for immersing screw piles, containing the base machine, on the platform of which an arrow with 30

In NTV

The crane device carrying the screwing mechanisms with the pivoting devices is equipped with lifting supports mounted on the platform. One end of each of which is connected to the platform by a hinge, and the other by means of fixing pillars, the lifting stands being made with longitudinal guides in which the pivoting devices of the screwing mechanisms are installed.

FIG. 1 shows the installation, general view; in fig. 2 is the same, top view. ,

The installation for immersion of screw piles comprises a base machine 1, on the platform 2 of which the lifting supports 3 are mounted, hinged to the platform at one end and the hinges 4 mounted on the edge portions of the platform at the other end. The supports 3 are made with guides 5, in which pivoting devices 6 with screwing mechanisms 7 are mounted for movement. On the platform of the base machine 1, sleeves for guiding the piles 8 are installed, and in the lifting supports 3, opening sleeves 9 and 10 are installed for

directions of piles 8. On the platform of the base machine, an arrow 11 is installed with a kpaiHOBHM device, carrying screw-down mechanisms 7. Outriggers 12 serve to ensure machine stability when driving piles.

The device works as follows.

When screwing up the vertical sei with the help of the guides 5 and the yawning device, the mechanism 7 turns into one: set to save the injection until the hole for the passage of the pile 8 in the mechanism 7 and the sleeves 10 or 9 match, it depends on the steps of the pile. Roofs, mechanism 7 for screwing in and bushings To are opened. IcpaHOM rises pile 8 and enters the mechanism 7 and the sleeve 10. The cover is closed in the insert 10, using the guides 5 and pdvb1 btyogd device b screwing mechanism is adjusted to obtain the required alignment of the pile 8 of the sleeve 10 and the mechanism 7. The covers are closed mechanism 7.

Next, the pile 8 is raised by a crane, the fingers are inserted into the holes of the pile, after which the pile 8 is lowered so that the ends of the fingers fall into the grooves of the screwing mechanism. The drive is engaged and the screwing process takes place. While the screwing process is in progress on a single mechanism, the second mechanism is set to screw up similarly to the first one.

When screwing the pile at an angle to the vertical with the help of guides 5 and the bridges device, mechanism 7 is installed until the holes for the pile 8 in the mechanism 7 are screwed into the sleeve 10. The covers of the mechanism 7 and the sleeve 10 are opened, and 8 are turned into the sleeve 10 and the mechanism 7

The cover of the sleeve 10 is closed, the screwing mechanism 7 is used with the help of guides 5 and the turner b to bring the required coaxiality of the pile 8 into the sleeve 10 and the mechanism 7.

The mechanisms 7 are closed. The lifting stand 3 together with the guides 5, the pivoting device 6, the mechanism 7, the sleeve 10 and the pile B is rotated relative to the hinge by means of a crane. With the fixing stand 4, the stand 3 is fixed at the required angle of screwing in the pile 8.

You can install at an angle and in another way.

The lifting stand 3 with guides 5, the pivoting device b, the screwing mechanism, the sleeve 10 with 5 using the crane 11 is rotated relative to the hinge and the fixing stand 4 is fixed at the required angle of the screwing in of the pile 8. Next, the pile-. It is cast on in the manner described.
