The device comprises a horizontal conveyor 2 mounted on the frame 1 for feeding the pipe layers consisting of a pair of endless chains symmetrical about a vertical plane passing along the axis X-X and spaced a distance that is significantly less than the length of the pipe barrel. without bell length. The chains of the conveyor 2 pass through gears 3 at the end and are driven with variable speed by a pair of synchronizers which are placed above the trolley for carrying out the package, so that the holder wall 26 is arranged parallel to the wall 37 of the trolley and does not interfere with the movement of the latter. The angle of inclination of the guide shovels for its longitudinal movement is equal to said angle of inclination of the walls and the base. After several layers have been inserted, the holder is lowered to the lower position and leaves a stack of pipes on the base 36 of the carriage. In this case, the wall 26 moves in a plane-parallel fashion and occupies a position between the wall of the carriage and the end of the conveyor, and the base 25 is below the base 36 of the carriage, 1 C. , 10 il.

gears 4 mounted on one shaft 5 transversely to the X-X direction and parallel to the overall feed direction of the pipes. The wheels 4 are driven by an endless drive chain 6 driven by a variable-speed motor 7. Conveyor 2 has teeth 8 for proper spacing of pipes with gaps

corresponding to the maximum length of the OS layer, Conveyor 2, moving continuously or in jerks, is intended to receive layers of pipes composed by laying them with a turn on

180 ° (jack), by laying them with a lifting device.

The frame 9 is equipped with a spade layer removal mechanism and contains longitudinal beams parallel to the plane of symmetry of the device, passing along the X-X axis, below and inside the longitudinal beams of frame 1 with a slight upward slope to the horizontal in the direction of forward movement of the pipe layers. On

beams 9 installed trolley 10 with rollers 11, Trolley 10 carries the frame 12 of the shovel. On frame 12, guides are mounted for a slider 13 carrying a pair of levers. 14 shovels, different

distances shorter than the length of the trunks of the transported pipes and neck distances between the beams of the frame 9, t, e. significantly less than 313

between the zeppymn branch of the conveyor 2. The lever H 14 are oriented perpendicular to the frame 12 and its slide 13 and set at an angle X to the horizontal,

to ensure -, package sustainability. The levers 14 have at their ends near the frame 12 a pair of teeth for a layer of pipes. A shovel with levers 14 is installed with the possibility of reciprocating movement on the beams 9 and raising and lowering on the frame 12 for removing pipes from the conveyor 2. For this, frame 12 is connected to Silozy Dilindrom 15,

 pivotally mounted on the support 16, the end of the piston rod of which is connected to the carriage 10, and the slide is driven by a cylinder 17, pivotally mounted on the support 18 connected to the carriage 10. At the end of the piston rod 17 there is a traction chain 19 (such as the Tall chain), which is attached to the lower part of the slide 13, after changing direction 90 around the pulley or gear wheel 20, on which it runs along an arc of a circle of 90 °. An intermediate holder is placed opposite the discharge end of the conveyor 2, which consists of a frame 21 with two columns. tilted bubbled with Y form an angle to the vertical and which are directed yuschimi-expandable to a pair of parallel and rigid bend (skoboobraznyh) brackets peremeschayuschihs synchronously. The brackets 22 are symmetrical to the symmetry planes passing along the axis X-X and are equipped with rollers 23 for moving on the frame 21. The synchronization of the movement is provided by known hydraulic means (not shown). These brackets 22 move between, the upper lolol; trolley for carrying out a package of pipes and a lower position under this trolley. Crochels 22 form three sides of the route (Fig. 3, 5, 6, 9, 10) and contain a wall 24 inclined in the ZZ direction, having a height greater than the height of the container 2, base 25, bearing surface or nezdo hold l Toe parallel longitudinal beams 9 and bracket 14, i.e., inclined at an angle X, the second wall 26, perpendicular to the base 25 and parallel to the frame 12. Wall 26 has a height slightly exceeding the height of the conveyor 2, and is inclined at an angle X to the vertical K1) us24

At the points 28 on a support mounted on the floor and connected to the end of the piston rod of the cylinder 27. The synchronous operation of both cylinders 27 is controlled by known hydraulic means. Between the frame 21 and the conveyor 2 there is a wheelless trolley for carrying out the package of pipes (Figures 1-3-10) and mounted for horizontal movement on the frame 29 mounted perpendicular to the conveyor 2. The frame 29 carries rollers 30 with fixed axles, horizontal and parallel to the xx direction. The rollers 30 are driven synchronously, for example, by a gear; by wheels 31 and endless chains 32 connected to a drive (not shown). The cart has a receiving pocket 33 in the form of a lattice with runners 34 located on both sides of the rollers 30 of the same row (Fig. 3 and 9). At the ends of the flooring of the receiving craman 33 there is a pair of support-angle consoles 35 on which the package of pipes rests. The base and side wall 35 of the cantilevers are inclined at the same angle X as the bearing bearing surfaces of the spade removal mechanism and the intermediate holder.

The base 36 of the consoles is located parallel to the base of the intermediate holder, and the side wall 37 is parallel to its side wall.

Each wall 37, therefore, is perpendicular to the base 36, parallel to the frame 12 and the slider 13, as well as to the holder wall 26. The width of the cart is less than the distance between the two brackets 14 in order to allow the shovel to be raised and lowered outside the cart, and also significantly less than the distance between the two brackets of the carrier, which allows the holder to raise and lower relative to the cart. The length of the cart is much less than the distance between the two - long beams of frame 1 and less than the length of the pipes, which allows the slinging machine 38 to apply slings around the package of pipes outside the trolley, on either side of it.

The device works as follows.

First, a layer of pipes, for example, in the amount of three pieces, laid with a 180 ° turn, is fed to the loading end of the pipeline to the upper 2

chain link reloading device. The shovel is at the same time in the lower position under the conveyor 2 (FIG. 3), the cylinder 17 is driven by the levers 14, affecting the chain 19. The shovel rises, fits under the pipe layer, lifts it above the conveyor and lays it all the way and gear teeth 14. The shovel stops rising at the end of the stroke of the cylinder above the conveyor 2.

The shovel feeds the pipe layer to the intermediate holder. The holder is at the same time in the upper position above the carriage for the removal of a layer of pipes at a height h between the bases 25 of the carrier and 36 carriages. The shovel is displaced in the direction of the holder by cylinders 15 acting on the frame 10, and is located above the transverse path of the trolley for carrying the layers and directly above the holder. This is the extreme position of the stroke of the cylinders 15 and the frame 10. The cylinder 17 now acts in the opposite direction to loosen the tension of the chain 19 and lower the shovel until the pipe layer lies on the base 25 of each bracket 22. The shovel continues to descend to the end cylinder stroke 17. Then the cylinders 15 operate in the opposite direction and take the shovel out of the plane of the body and transfer it under the conveyor 2 (FIG. 3). After laying the first layer, the shovel with the levers 14 can only descend to the level of the first layer, not income until the end of the cylinder 17. After laying the second layer, the shovel finishes its release at the level of the second layer. Such laying is carried out using known automation means. Loading the holder includes a reciprocating movement until the holder is completely filled each time after laying the layer, two gaskets are laid on it — wedges 39 necessary for the passage of the pipe sockets, which protrude relative to the walls 37 during the movement of the cart for the removal of the packet in the direction of YY, without colliding with the walls of the holder’s 26 brackets when stopping.

The removal of the package of pipes on the trolley for carrying out the package takes place at the lower position of the holder brackets on the bases 36 of the receiving pocket at a distance d between the walls 26

26

and wall 37. The cart travels along the Y-Y axis in which the package is delivered to the slinging machine 38 via rollers 30.

The brackets 22 of the holder do not mark the movement of this cart, since one of them is placed in a lower position in an opening 40 closer to the machine 38 in frame 29 between the rollers and the other behind the end of frame 29. After moving the cart with package

from the area of the brackets 22 holders po4

the latter rises to the upper position above the trolley in order to receive new layers of pipes, and the cycle repeats. At the same time, the holder frees the trolley to return to the loading position.
