one and a half lengths of section 6, and single-hinged with a hinge in the form of one, is carried in a new telescope 11, mounted on: a running carriage 10, a rear roller support 5 of a section and a roller support .7 pipelines are placed side by side (on the sides of the mounted and welded in the root seam of the junction 12) in the area of the end of the frame 9. The latter is equipped in the front part with a curved lodgement 13 for the removable centralizer 3, rigidly strengthened at the level of the receiving surface of the roller support 4 and 5 with the ability to interact with its end when the tractor 1 is fed back with the lower part end section and 6. Welding equipment 2 razmesche- but at the end of the frame 9 by moving it along the rollers 14. Because of the considerable weight of the welding equipment is expedient to equip the frame 9 bonded with it additional undercarriage 15

To weld the seams in several passes, the line is equipped with the corresponding number of passes by the rear running trolleys 16, equipped with welding equipment 17, and the frame 9 is equipped with a winch 18 with a rope (ropes) 19 of the running rod of the trolley (trolleys) 16 and its subsequent supply of equipment 17 to the facing joint (s) of the pipeline 8.

, Frame 9 can be double-handed, and the centralizer tool tray 13 and winch 18 are mounted on the rear jib.

The joint in its bodies of the casing 11 is equipped with upper and lower guide rollers 20 / mounted on the axles 21 in the longitudinal ducts 22. located on the sides of the undercarriage 10 by means of the transverse axis 23 supporting them, and the telescope travel stopper is made in the form of interacting with the rollers 20 and transverse plates 24 .. ..- -... fixed at the end of linearly movable parts of the joint 24 .. ..- -...;

In order to ensure the possibility of conducting work on rough terrain, the frame 9 is equipped with an additional undercarriage 25, located in front of the main maintenance unit and equipped with a universal swivel joint 26 between them, with the formation of a narrow front 27 and rear extended 28 structures. In turn, the part of the frame 9, located between the main 10 and the rear additional 15 bogies, also forms an independent structure 29, hinged to the axis. 22 trolleys 9. At least one of the trolleys 10 and 25 is provided for the same purpose with a height and lateral position adjuster 30 of section 6,

Each of the regulators; made in the form of a triple device with the formation of the middle channel from the hollow frame 31 of the undercarriage 10 (or 25). The lower and upper channels are made in the form of transversely movable vertically through ducts 32 and 33, the Lower duct 32 is suspended by a flange at the edges of the window 34 of the frame 31 and is equipped with a hinged pantograph 35 placed in its cavity from twice repainting units. The upper box 33 is mounted on the upper links x of the pantograph 35. The lower and upper pantograph links on one side thereof are connected to the boxes with hinged fingers 36, and on the other hand by means of sliders 37 placed in horizontal slots 38 of the boxes. Between the lower links of the pantograph in the lower box 32 and between this box and the frame 31 of the undercarriage, there are placed Mechanisms 39 and 40 for changing the height and lateral displacement of the pantograph, which are made in the form of horizontally arranged force digits.

The regulators 30 instead of the carts 25 and 10 can be combined with ero-support 4 and 5 and carry the rollers 41 of the latter on their upper boxes 33,

The pipe installation line operates as follows. The arriving section 6c is overloaded by the vehicle pipe-layer onto the roller rollers 4 and 5. After that, the reverse of the tractor 1, it is linearly fed to the joint 12, which is carried out as a result of the centralizer bed 13 mounted on the frame 9 and pressing against the front end with its rear end the end face of section 6. In this case, the front roller support of the 4 section is shifted back together with the structures 27 and 28 of the frame 9, and the rear roller support 5 remains fixed on the ground of the mass carriage 10 of the welding equipment 2 and the structure 29 of the frame. In the line for pipelines of large diameter, the additional carriage 25 of the frame is biased, and the additional carriage 15 of the line present in it is locking. The structures 27 and with respect to its structure 29 are mixed in the telescope 11, where) the free ends of the beams of the structure 28 roll along the lower and upper guide rollers 20.

If the line is located on rough terrain and its frame breaks in the hinge 26 and on the transverse axis 23, then the next step introduces one or two regulators 30 of the high and lateral position of the section. When the power cylinder of the mechanism 39 changes the height changes (as a result of the movement of the sliders 37 in the slots 38, the approach or

removing the ends of the lower and upper links of the pantograph 35 of the regulator, as a result of which the upper box 33, resting on the lower 32, raises or lowers together with the rollers 41 and section b. When the power cylinder of the lateral displacement mechanism 40 is turned on, the lower box (together with the pantograph, upper box and section) moves to the left or right by its flanging along the edges of the window 34 of the trolley frame 31. As a result of such manipulations, the rear end of section 6 assumes the position necessary for welding relative to the end of pipeline 8.

The final stages of preparation for welding are sliding the welding equipment 2 onto the joint 12, which occurs as a result of rolling of the rollers 14 along the beams of the frame structure 29 under the action of its own drive, as well as the feeding of the centralizer 3 to the joint 12.

Simultaneously with the completion of the preparation for welding the root layer of the joint 12, installation of additional equipment 17 on the facing joint is carried out, for which the rear bogie 16 is linearly fed to the cable 19 of the included winch 18.

After the semi-automatic welding in carbon dioxide is completed, the centrator is removed to the lodgement 13, the welding equipment 2 is rolled back, the ropes 19 are somewhat glorified, and the regulators 30, if they are located on the bogies 25 and 10. are moved to the lower position. After that, the pipe installation line is moved one step forward. At the beginning of the movement of the tractor 1, the structure 29 of the frame 9 remains motionless for some time: until the transverse plates 24 of the telescope travel stops interact with the guide rollers 20 of the telescope joint. As a result of the movement of the frame 9, the rollers 41 of the 4.5 and 7 rib rollers are rolled, the lower generatrix of the newly formed section of the pipeline 8 and the main part of the line is set free to receive a new section. In this case, the movement of the trolley 17 is carried out by means of the rope 19 of the winch 18 in its inhibited state. The movement ends when the roller bearings 5 and 7 occupy a close symmetrical position relative to the end of the pipeline, which is supported at this moment on the frame 9 through the roller bearings 7.

After that, the cycle repeats.

Thus, by making the frame horizontal and telescopic and placing the stop in the form of a centralizer lodgement in its front part, the use of a pipe layer for linear feeding the mounted section to the joint is eliminated, as a result of which the feeding time is reduced and end impacts are excluded, which 5 increases productivity and labor safety during installation.

The pipe assembly pipe assembly line contains side hoppers located on the chassis, a lateral feed unit of the next section 6 to the mounting axis and at least a pair of roller bearings located on this line with the height and transverse adjusters 30 of section b when it is linearly supplied for installation and longitudinal rollers 41. The arrangement of the regulators 30 is described in detail in the first invention. Each of the rollers is equipped with a curved lodgement placed over its regulator.

0 42 with a longitudinal hinge rod 43 for its attachment and axial rotation and extreme rollers 44 for receiving the rolling section 6 into it. The bed 42 is equipped with a mechanism 45 for its transverse rotation in

5 is a view of a power cylinder located horizontally between it and the upper duct 33 of the controller. Each of the bunkers is made in the form of a pair of inclined brackets 46 and 47 placed in transverse planes with a flat roll surface 48 of sections 49 tangential to the lodgement curve 42 on the surface of its rollers 44 and drive cut-off sections. Thus, rotary beds 42 with rollers 44 and mechanisms 45, and

also inclined surfaces of 48 bins

with cut-offs form a device for transverse feeding of the next section 6 to the axis

installation.

0 Each of the cut-offs is made in the form of a double link hopper pivotally hinged below the surface 48 of the roll-up hopper, one of the links of which is formed by a rocker arm 50 bearing on a free shoulder 51,

5 and the other with a power cylinder 52.

The running chassis is made in the form of coupled, for example, hinge 26, running trolleys 25 and 10, and the roller bearings and crowns of the matte 46 and 47 of the hoppers are mounted on frames 31

0 trolleys.

The pipe accumulator of the pipe-mounting complex works as follows. The hoppers 46 and 47 are loaded from the vehicles with a crane. For submission

5 of the next section 49 on the axis of the pipeline 8. lodgement 42, actuating the power cylinder of the mechanism 45, rotate left or right around the axis of the rod 43 to a position where the surface of the hopper 49 and the top of the surface of the roller 44 coincide. At

If necessary, the position of the roller is corrected by turning the power cylinders 39 and 40 into operation. After that, the power cylinder 52 is turned off, and as a result, the roller 50 of the rocker 5.1, due to the rotation of the latter, begins to approach the drive roll surface 48, ensuring that the next section 49 rolls to the lodgement 42. After the roller 50 is recessed into the surface 48, the section, under the influence of its own weight, passes to the end roller 44, and then to the lodgement rollers 41. As soon as the section passes the recessed roller 50, the cutter returns to its original position by known methods if the capacity of the hopper is calculated for 2-3 sections / When the power cylinder of the mechanism 45 is returned to operation, the section rolls over the surface of the rollers 41. into in the end, it occupies a position close to the axis of pipeline 8. The final position of the section, which is now axial to this pipeline, is (now 6) as a result of the corrective operation of the power cylinders of mechanisms 39. and 40.,. ..- ..

Thus, thanks to the use of a lodgement device of the lateral feed of the next section to the mounting line in the pipe feeder, its design is simplified.

It should be noted that the foregoing inventions can be used separately in pipe assemblies. Their joint use in the complex depicted in the drawing solves an additional major problem - it provides increased operational productivity by eliminating downtime due to irregular delivery of sections by pipelines.

An example of implementation. The complex and pipe storage are designed to operate primarily along the indicated road with pipes and sections 12-24 m long and 1420 mm in diameter, using standard welding equipment, a centralizer, undercarriage and T-330 tractor.
