The invention relates to devices for welding plastic-molded pipes and can be used for welding plastic pipes when laying pipelines or distribution gas pipelines.

The aim of the invention is to improve the quality of the joint when welding long pipelines by reducing the stress in the welds from bending,

FIG. 1 shows a schematic of an installation for welding plastic pipes; FIG. 2 is a view A of FIG. 1; FIG. 3 is a section BB in FIG. Fig, 4 is a section bb In figure 1; FIG. 5 is a view of FIG. 2; figure 6 - type D figure 5

The installation for welding polymer pipes contains a covered platform containing the base 1, in which the power mechanisms are located and the operators work, and the upper part 2, where the pipes are located, the drive roller table 3, the cutter 4, the hydraulic drive station 5, two self-contained pairs of stationary 6 and 7 clamping clamps, each of which is connected to the power drive 8, supporting

roller 95 ensures that the end of the platform descends from the plate is compressed by force of sediment into the trench of the whip; to support the pipe and lay it on an inclined roller table 13, a winch 14 that serves to move the platform along the trench using a cable 15, a shaft 16, on which an end face 17 and a heater 18 are installed, an electrical unit 19 providing electricity to all consumers.

Fixed 6 and movable 7. clamping-g position for work, fixed clamps consist of three parts: lower sector 20 ,. the left sector 21. and the right sector 22, connected by a folding bolt 23. The clamps 6 and 7 are mounted on the frame 24, having rollers 25 o On the frame 24 there is a fixed clamp 6 and an actuator 8, which is a hydraulic cylinder, the stem of which is connected to movable yoke 7 ,.

The frame 24 with the clamps 6 and 7 is mounted on the guide 26 one end of which is shimrically connected to the stand P 5 and the other end rests

It is poured on the guide rail 26 and the next pipe is fed to the inclined IS roller table and moves to the contact of the ends.

After clamping the ends of the rod and pipe, the cycle of processing and welding of pipes is repeated. After finishing the processing and welding of pipes in the second pair of clamp clamps, the operator releases the first pair of clamps and does not move them to their original position. For loading the table II lift, turn on the winch 14, moving the installation to a new location. Depending on the size of pipes in this

the height-adjustable stop 27. The guide 26 has a spring-loaded pin 28, which serves to hold the autonomous pair of clamps in the initial position. To reduce stresses in welded grooves, the inclination of the guide 26 corresponds to the inclination of the pipes to be welded.

The installation works as follows.

The first of the welded pipes along the co-mandger of the coaster rolls onto the watering roller table 3, moves forward 5 to the stop and the deflecting roller 12 is placed on the inclined roller table 13, which feeds it to the noct to be fixed in the clamp 6 with the necessary after departure, then the second pipe is fed in a similar way until it stops at the first one. Having fixed the second pipe in the clamp 7 by the force mechanism 8, the second pipe is retracted providing the input of the trimmer 17, then the pipes are compressed by force actuator B, the ends are machined and fur; input its heater 18,

ki Having welded the pipes in the clamps, turn on the winch 14 and the installation moves to the required distance. In this case, the first pipe is laid in a trench, and the first pair of clamping clamps holding the weld under the upsetting force, automatically moving, deflects roller Q, which then automatically returns to its original position and supports the pipe, which comes off the inclined roller table 13. Second a pair of clamp clamps is fed to lift table 11, rises to its original position for work, setting

It is poured on the guide rail 26 and the next pipe is fed to the inclined IS roller table and moves to the contact of the ends.

After clamping the ends of the rod and pipe, the cycle of processing and welding of pipes is repeated. After finishing the processing and welding of pipes in the second pair of clamp clamps, the operator releases the first pair of clamps and does not move them to their original position. For loading the table II lift, turn on the winch 14, moving the installation to a new location. Depending on the size of pipes in this

Installation may have two or more autonomous pairs of clamping clamps.

The installation can be moved both by the vehicle and by means of the winch 1A. which can be attached to the bark or to the frame of the grooves.

Due to the presence of at least two autonomous pairs of movable and fixed xof-fyTOB, associated with a power actuator, simultaneous laying of welded pipes into trenches and welding of subsequent pipe billets is carried out, as well as due to the presence of a covered platform for storage and mechanized supply of pipes for welding, labor productivity is increased, the working conditions of operators are improved.

Placing the pipes on a covered platform protects the pipes from adverse atmospheric precipitation and sunlight, which as a result improves the quality of the weld, i.e., the quality of welding.

Each autonomous pair of clamping clamps in the initial position is mounted on a guide at an angle of inclination corresponding to the angle of inclination of the pipes being welded, which reduces
