Fig. 5 pressing of piles or other similar building structures with the use of a drilling rig, and is an axonometric image.

Drilling rig 1 for drilling wells for piles or other similar constructions according to fig. 1 contains a vertical riser 2 and a horizontal platform 3, the front part of which is rigidly fixed to the lower part of the riser 2. The platform C is installed, preferably, on two means 4, for example, anchor carts 4, which are fixed to the bottom of the platform C by means of detachable threaded connections, and one is installed on the sv) with the support guides of the two main structures 7, for example, the main (bridge) beams 7 of the self-propelled base. structure 8 of a machine for driving piles or other similar building structures (fig. 2, 7) so that what? the drilling rig 1, for example, on the rollers 9 of the anchor carts 4 can move along the support guides 6 along, in fact, horizontal main (bridge) structures 7, for example, I-beam main beams 7 in the direction shown in fig. 1, 7 is indicated by the arrow 10. If necessary, a larger number of -I anchor carts 4 can be used, for example, two relatively short carts 4 for each support guide 6. Actually, the term "anchor" is used in the sense that the cart 4, like anchors, has a means (14), for example, two hooks 14, which are adapted to prevent the lifting of the trolley 4 relative to the guide 6 by any force directed up 5o The indicated anchor carts 4 can be made similar or identical to the anchor carts of the fuel 1 pressing unit 47 of the machine. It is obvious to a specialist that in other implementations, for example, itself

The I-beam main beam 7 can be used as a support guide 6, while the upper shelf of the main beam 7 will be the indicated upper part of the support guide 6. It is also obvious that the upper part of the support guide b can have one lower surface, for example, in the case of making it from the channel, and the anchoring dv Cart 4 one hook 14. In addition, instead of rollers 9, sliders with anti-friction polymer gaskets or other elements similar to rollers or sliders can be used.

F) Removable threaded connection 5, with the help of which the anchor trolley is fixed to the platform 3, (fig. 3) which can include at least one anchor bolt 11 with nuts, which has a head located in - 14 - or A-shaped groove 12, which is made on the upper part of each anchor trolley 4. Holes 13 for the rods of anchor bolts 11 are made in the corresponding side parts of the platform C.

The riser 2 has a I-beam section, for example, the riser 2 is made of a regular rolled I-beam, while the side parts of the riser, which lie in the planes parallel to the direction 10 of movement of the drilling rig 1, are formed by the shelves 15 of the I-beam. Guides 16 are welded to the conventional front edges of the shelves 15 so that guide grooves are formed between them and the wall 17 of the I-beam, in which the sliders 18 of the lifting platform 65 of the drilling mechanism 19 are located. The specified lifting platform has vertical 20 and horizontal 21 plate-like parts, on the first of on which the specified sliders 18 are mounted. An electromechanical drive for rotating the drilling tool 23 is mounted on the horizontal part 21, for example, a gear motor 22, the upper end of the drilling tool 23, preferably made in in the form of a compacting drill 23. The compacting drill 23 has a hollow body, which includes a conical lower end part 24 and a tubular main part 25, which can be made sectional. In the wall of the drill body 23, holes can be provided adapted to fill the internal cavity of the drill body with ballast material or to remove ballast material from it to adjust the weight of the drill 23. The screw blade 26 is made on the body of the drill 23.

As can be seen from the drawing in fig. 1, the drilling mechanism 19 is located on the conventionally named front side of the riser /0 2. and the platform C is located on the opposite rear side. Moreover, in the front part of the platform C, a cut-out for a drill 23 is made. As can be seen from the drawings, the drilling rig 1 is oriented in such a way that its drilling mechanism 19 in relation to its vertical riser 2 is located on the side of the first (for example, the one shown near in Fig. 1) from two opposite ends of any main beam 7. However, in another embodiment (not shown in the drawings), which is not worse, the drilling rig 1 can be oriented by the drilling mechanism 19 in /5 the opposite direction, that is, so that the drilling mechanism 19 is turned to the opposite second end of the main beam 7.

On the upper part of the wall 17 of the riser 2, a node 27 of the upper fixed blocks, intended for storing the rope 28 of the lifting rope mechanism adapted for forced lifting of the drilling mechanism 19, is fixed on them. The node 29 of the lower movable blocks, on which the rope 28 is stored, is fixed on the upper part of the vertical part 20 of the lifting platform of the drilling mechanism 19. The end of the rope 28 is wound on the drum of the lifting winch 30, which is installed on the rear part of the platform C and has the usual construction for winches.

If the main part 25 of the drill body 23 is made sectional from the main and additional sections, the riser 2 is also made sectional from the main section 31 and the additional lower section. At the same time, the horizontal platform Z is rigidly fixed to the lower part of the main section 31 of the riser 2, at the lower end of which there are disconnecting joints Connection 32 for docking the main section 31 with the additional lower section (not shown in the drawing according to Fig. 4) . The removable connection 32 can be made, for example, in the form of plates with holes 33 for bolts. (8)

For forced movement of the drilling rig 1, it can have a separate individual means 34, for example, a stepping hydraulic power mechanism 34 (Fig. 5, 6). The specified moving mechanism 34 includes a double-action hydraulic cylinder 35, the body 36 and the rod 37 of which are connected by hinges to the respective Ge! with the first Z8 and the second 39 beams. On the end parts of the first beam 38, sliders 40 are fixed, which are adapted to slide, for example, along the guides 6 of the main bridge beams 7, and on the sliders 40, hinges 41 are attached to rotary stops 42, adapted to rest on the vertical surfaces of the stops 43, which are installed in steps M along the main beams 7, and the upper horizontal surfaces of the last 44. Moreover, each stop 43 is welded to the upper surface 44 of the main beam 7 and the sole surface of the rail profile of the guide 6. Thus, "

Ззв5 The set of stops 43 increases the reliability of fixing the guide b to the upper surface of the main beam 7. The ends of the second beam 39 are connected to the anchor carts 4, the horizontal platform C or any other element that is part of the vertical riser (2) or immovably connected with it.

The drilling rig is used in this way.

A rail track 46 is laid on the prepared base of the construction site from rail sheets 45, on which the necessary structural variant of the basic structure 5 of the machine for pressing piles or other similar building structures is assembled from individual nodes. Fallow is installed on the main beams 7

And the pressing unit 47, which is adapted for pressing in piles or other similar building materials? structures, and drilling rig 1. Next, block counterweights 48 and a hydraulic station with a control panel 49 are installed, making all the necessary electrical and hydraulic connections.

Using the stepping hydraulic power mechanism 34, the drilling rig ve 1 is moved along the main beams 7 in the direction shown in fig. 71, 7 is indicated by the arrow 10 and is, in fact, perpendicular to the direction 52, before the installation of the compacting drill 23 above the point of pile depression. If necessary, in order to reverse the direction of movement of the drilling rig 1, turn the rotary stops 42 to the required position so that they can rest on the right or left vertical surfaces of the stops 43.

Ge) To drill a well, rotate the drill bit 23 with the help of a motor-reducer 22 and ensure the lowering of the drilling mechanism 19 under its own weight by a lifting rope mechanism, rotating the drum of the winch 30 in the direction of winding the rope 28. After completing the drilling of the well, rotating the drill bit 23 in the opposite direction direction of its rotation during drilling, and at the same time lifting the drilling mechanism 19 with the lifting rope mechanism, rotating the drum of the winch 30 in the direction of winding the rope 28, remove the drill 23 from (F, the well and raise the drilling mechanism to the upper position with the lifting rope mechanism. ka In versions of the machine, which are shown in Fig. 1, 2 and are characterized by the fact that the fuel press 47 and drilling 1 units are installed on common main beams 7 and for simultaneous joint forced movement of the drill are connected to each other, for example, with the help of a rigid element, after drilling a well by with the help of 47, 1 stepping hydraulic power unit common to both units mechanism 34 divert the drilling rig 1 along the main beams 7 from the well. The pile is installed in the well with a load-lifting crane, and with the same mechanism 34, the pile pressing unit 47 is moved onto the pile until it is inserted into the middle of its riser 53, and then the pile is pressed in using the step-by-step pile pressing mechanism 65 (not shown in the drawings) of any known design, which is adapted to rest on the head of the pile and exert compressive force on it.
