The end wall 63, the plate 68 and a set of spacers 62 are connected by means of a tightening element 72, which is passed through the spacers and through the opening 71.

The device for mounting the wires of the air line operates as follows.

 The base 1 with the case 2 fixed on it and with two infinite chains 7 strung on it on sprockets 5, 6 is installed at the beginning of the anchor section of the air transmission line, approximately 80 m from the anchor support 73.

In the housing 2, a carriage 3 is installed, while its grippers 46 are put into operation. For this purpose, the rods 48 compress the springs 50 (Fig. 13) until the latches 51 under the action of the springs. 53

will not enter the slanting notches 49 of the rods 48. The carriage 3 is inserted inside the housing 2, and on rollers 60 along the guides 13,14 move it to the stops 25. With this movement of the prefix 3, the shanks 40 of the screwing mechanisms 37 interact with the bevels of 20 wedge-shaped projections 18 and raise the screwing mechanisms 37 in the sockets 38. When these mechanisms are raised, the springs 41 are compressed. At the same time, the drive gears 35 of the gearboxes 34 engage with the rack racks Jb. The sprockets 9 connect the chains 10 with the brake device 11, driving two chains 7. A similar connection is necessary for the functioning of the mechanisms of the device. This connection allows you to get by with one engine, which is installed on the winch 74 at the end of the anchor section of the overhead line behind the anchor support 75.

Connect the counter 76 from the length of the wire with the actuator 28.

Thanks to this joint, made in the form of a flexible or rigid connection, it is possible to rotate the shaft 27, having right and left helix-like cuts, and move in axial direction along the shaft 27 of the sleeve 29.

The device is installed; cassette 4 with a set of pre-assembled in it on the guides. 64 spacers 62. The cassette is pushed into the housing 2 from the side of the braking device 11 and secured to it and the end wall 63. Then the protrusion 69 of the plate 68 is connected to the sleeve 29. By rotating the sleeve 29, its groove 30 is put on the protrusion 69 and attached to the latter, using the holes 31 formed in the sleeve and the feed nlate. These m connections. A supply plate 68 is connected to a meter 76, and the wires are connected. Then, the securing struts are removed to the end wall 63 of the element 72 which binds them.

The wires 67 are unwound from the drums 77, they are passed through the brakes 11, the counters 76 measure the length of the wire. They are pulled into the housing 2 along the grooves of the anti-roll rollers 78 and along the grooves 66, after which they are fixed in the position required for rolling. After passage of the rollers and bevels, wires are pulled through openings 32 beyond the device.

The ends of the wires 67 are connected to the transition element 79. This element can be made in the form of a rigid pyramid of rod-like elements, which are fastened together at the base by cross-links. The top of the transition element 79 is attached to the rigging cable 80. The rigging cable 80 is pre-rolled within the anchor section on the rollers 81 in the cage 82, suspended by traverses 83 of the supports 73, 75 and 84.

Behind the anchor support 75, the winch 74 is turned on and the rigging cable 80 starts to wind. The wires 67 are actuated by the braking devices 11, the chains 10 and the associated chains 7 of the device.

After the required interval has been measured, the counter turns on the drive 28 of the shaft 27. When the shaft 27 rotates, the sleeve 29, moving along the cartridge 4 towards the Karetx 3, carries along the plate 68, and together with the last, carries the spacer 62 along with it.

, The spacers 62 with their lower and upper dies with the bolts 58 fed into them freely contact with the guides of the 64 cassettes with half-grooves for wires. The guides 64 are of such a cross section that when they are covered with nlashchiki between them (from the wires) a gap is formed, allowing the wire to freely enter the half-grooves of the dies.

Moving along the guides 13 and 14, the strut approaches the lead-in edges of the carriage 3. Wires 67 as they descend

The 5 spacers from the cassette guides 64 enter through the slots between the lower and upper dies into the cages and fit their half of the plates under the wires. Further movement of the base plate 68, the spacer is pushed into the carriage 3. Wires 67, coming off the bevels 65, which frame 64, are located in the half-grooves of the subwire, and the bolts 58 of the plates enter their heads 59 into the grooves 59. With the further movement of the spacer inside the carriage a gradual approach

5 dies. When this strut presses on the grippers 46, squeezes them, the entrance between them. Then the strut extends beyond the protrusions 47 of the grips 46. In this position, the counter 76 turns off the drive 28 of the shaft 27 and further

0, the spacer is fed into the cassette, and the spacer at this time presses the protrusions 52 of the latches 51 (FIG. 13). By pressing, the latches 51 emerge from the slanting notches 49 of the rods 48. The freed rods 48 under the action of the springs 50 engage with their grips 46

5 spacer in the carriage and press it to the limiting stops 56 in the carriage. During this movement, the spacer presses against the protrusions 44 of the levers 42, which press the teeth 43 towards the chains 7 to contact them with the teeth 8 made on these chains. At the same time, the body of the spacer acts on the pushers 54, which press the stops 25, thereby ensuring the movement of the carriage inside the housing 2.

When moving the carriage 3 tail 40

5 of the screwing mechanisms 37, as they descend from the bevels 19, the wedge-shaped protrusions 18, release the springs 41 of the screwing mechanisms 37, causing them to go down in the slots 38 onto the heads of the bolts 58. Gears 34 that are in engagement with the rack 16 and gears rotate the gears 34 , and the latter, through flexible rollers 36, transmit this movement screwing up the mechanism of 37.

By the end of tightening the bolts 58 carriage 3

5 fits wedge-shaped entrances 18 with bevels 19 located at the end of housing 2 on the side of the power line and to the protrusions-stops 22. In this position, the spacers 62 are fixed on the wires, as the bolts 58 on the dies are tightened, and the screwdrivers 37 after Ensuring this puff is stalled. Upon further movement of the carriages ;: 3 shanks 40 of the screwing mechanisms 37, lifting along the bevels 19 wedge-shaped projections 18, lift the screwing mechanisms 37 in their sockets 38, compressing the springs 41 and releasing them from engagement with the heads of the bolts 58. At the same time, the rods 48 come into contact with the protrusions-stops. 22 and compressing the springs 50 before the latches 51 enter into the slanting notches 49. As a result of the contacts with the stops 25, the limiting stops 56 are pressed, and the tooth 8 on the chains 7 (Fig. 9) break out of the teeth 43 carriages 3. Carriage 3 stops and is fixed strut wires entrained wires from the carriage on the support. After the spacer 62 leaves the carriage openings 32, the levers 42 with the teeth 43 and the pushers 54 return to their original position. As soon as the teeth 8 fixed on the continuously moving chains x 7 wrap around the sprockets 5, they will come into contact with the projections 61 of the carriage 3 and will lead it in the opposite direction to the cassette 4 following the next strut 62. During this movement of the carriage 3, its shanks 40 will go off the bevels 19 of the projections 18 and release the springs 41 of the screwing mechanisms 37. Under the action of the springs, the screwing mechanisms 37 are lowered in the slots 38. Simultaneously The limiting abutments 56 will also come off the wedge-shaped protrusions 24 and, under the action of their springs 57, will again block part of the openings of the windows under the cloaks. Upon further movement of the carriage to the cassette 4, the shanks 40 interact with the bevels 19 of the protrusions 18 and, compressing the springs 41, raise the screwing mechanisms 37 in their sockets 38. The carriage 3 itself stops at this time, because after pressing out its 25 tooth 8 chains 7, the envelopes of the asterisks 6 at this moment, come out of contact with the protrusions 61 of the carriage (Fig. 10). After the entire set of spacers 62 has been used up in the cassette 4, before stopping the winch 74 with the help of a reversing drive 28 (or manually), the plate 68 is returned to its original position (FIG. 6) and the winch is turned off. Then the sleeve 29 is disconnected from the plate and the cartridge 4 is removed from the device. Then a new cassette with spacers is inserted into the device and, after it is connected, they continue rolling the wires, turning on winch 74. To splic the wires, they stop moving the rigging cable 80, i.e., stop winch 74: The wires are spliced to the braking device 11, both it and all subsequent elements of the device freely pass couplings or welded joints on the wires. To secure the spacers to the wires, instead of fastening the plates with the bolts previously inserted into them, the fastening of the dies with a bolt and nut can be used. In this case, the operation of the device will be similar, however, through grooves for the bolt head with lead-in chamfers are made in the carriage to avoid turning the bolt heads when tightening the nut. Depending on the number of wires in the split phase, only the configuration of the carriage itself and the window openings in it under the struts change. However, the carriage can be made universal for any number of wires in the split phase. This device will find application in the construction of air lines with a voltage of 330 kV and above, performed with split phase conductors and with struts.
