Thus, the drive energy produced by the diesel engine 19 is transmitted via a liquid speed reducer 20, a first shaft 21 and a front speed reducer 22 to drive a hydraulic pump 23. The hydraulic pressure generated by the hydraulic pump 23 is transmitted to the front 24 and the rear hydraulic motor co50

Thus, the wagon for pulling the wire is activated during its operation.

worn on the respective drums 33 and 34, are unwound from the drums and guided through the unit 10 for the regulatory moment of the drums with unexpected braking.

In response to an electrical signal transmitted from the hook detection unit 7, when its antenna arm comes in contact and the hook 42 is installed, the temporary suspension clip 11 is supplied for tensioning, the rearmost ends of these wires are connected to the inactive elements 35 and 36 of the carrying cable and the contact wire prepared in advance on the end support 37, from which the wire should be pulled out. In the device 10, tension regulators, the carrying cable 14 and the contact wire 15 are passed through the corresponding groups of rows of rubber, the rollers 38, which are located opposite each other, in such a way there is an eye on them. tonic at hydraulic pressure (see Fig. 6, 7 and 8). The rubber rollers are attached to the respective axles 39 .. The axes 39 of each of the several rollers are connected by gears 40, and one of the shafts is connected to an electromagnetic braking mechanism 41. Electric currents of a certain magnitude are applied to this braking mechanism 41, thereby producing braking forces proportional to these currents to apply tension in the order of 1000-1500 kg to each of the wires, while the car to pull the wire moves forward at a predetermined speed. Machines 12 and 13 for pulling wires, drums. 33 and 34 are also equipped with hydraulic brakes. In doing so, each of the two wires, when they are run between the drums 33 and 34, is applied a maximum tension of 300 kg and a tension control unit 10 designed to prevent sagging and clearance or the presence of stretched loops in the two wires 14 and 15 due to s at a certain distance from this point, for example, at distance 10, and when approaching a hook 42, the unit for unloading temporary suspension clamps functions by unloading temporary suspension clamps 43, 44 so as to connect the carrying cable 14 and the contact wire 15. The wire suspension unit functions in response to the electrical distance meter signal, starting horizontal and vertical movements and placing the suspension wires 14 and 15 into the grooves of the guide rollers 45 and 46 and the guide rollers 47 and 48. Then in response to the electrical adjustment signal from the hook detecting unit 7 of the suspension frame 49 and the vertical shafts 50 supported by the frame 49 and, in turn, supporting the rotating rotors 45-48 while rotating, are lifted by the mechanism described below, while lifting the carrying cable to naruzhennomu position of the hook 42 and placing the wire in the bend of the hook. As soon as the carrying cable is suspended in this way to the hook 42, the moving parts of the wire suspension unit move back to their inoperative positions, and they wait for the subsequent temporary suspension clamps 43, 44, which are unloaded 10 m before the subsequent hook. The described cycle of operation is repeated at each position of the support and hook 42, whereby the wires 14 and 15 are stretched when there is high tension and are installed continuously. The end point of the wire pulling operation is a pre-installed terminal support 51, on which there are inactive parts .52 and 53 of the wire. These parts of the wire are fixed by means of the fixing unit 9 at high tension, equal to the tension of the wire at its installation, and are connected respectively to the suspension wires 14 and 15. The old or unfit contact wire is replaced in accordance with the sequence described below. (see figure 4). The additional work platform 6 rises to a height corresponding to the height of the contact wire 15. The new contact wire 15 unwinds from Baraba 11046 to 34 machines for drawing the wire 13 and passes through the upper group of rubber rollers 38 of the unit 10 for tension adjustment and above the upper directions of the roller 8 of the unit 8 for hanging the wire, and then the end of the wire is connected to the inactive part 53 of the contact wire. Since the high tension is communicated to the new contact wire by means of a tension control device 10, the suspension wire device 8 that lifts the new contact wire is hydraulically actuated by manual adjustment, following the already installed support cable 14, and temporary suspension wires. The clamp1 is mounted manually on the overhead wire at the back of the device 8 for suspending the wire. In this way, the installation of a new contact wire is carried out continuously. On the other hand, at the same time, the old contact wire 17 is disconnected from the carrying cable 14 at a point above the working platform 5, passes over the guide rollers 54, 55 and 56 and through the roller on the yoke 57, located below the working platform 6, To the tensioning machine 16 mounted on the platform 1, winding on the tension drum 58, while the roller on the traverse directs the old wire to the drum with successive alignment of the winding. Upon completion of the drawing and installation of a new contact wire 15, the tension of the old contact wire 17 is simultaneously terminated. The hook detecting unit 7 has an antenna lever 59 for detecting hook 42, which is supported by a support 60 and on which the carrying cable 14 is suspended. The antenna lever 59 at its rear end can rotate, making turning movements up and down, and in the normal position it is directed forward. A switch 60 is mounted at the front end of this lever 59 for contacting the hook 42. The horizontal and vertical movements of the antenna lever 59, corresponding to its normal retracted position, are electrically detected using potentiometers 61 and 62. At this time, block 8 for suspending the wire is in its lower abutment position. As shown by the solid lines in FIG. 13. In contact with the hook 42, the switch 60 is triggered by starting at this distance (not shown, n), contained in the unit 10 for adjusting the tension of the wires, which counts or measures electrically the distance that the car passes from the detection point but. Then, when the block 11 for supplying temporary suspension clips reaches a point 10m from the hook 42, this device functions by discharging one or more suspension clips 43 and 44, whereby the carrying cable 14 and the contact wire 15 are connected. As a result, one or more time pods under the spring clips are located respectively at a distance of 10 m in front of and behind each pillar. As the car moves further and the unloaded temporary suspension clip passes by one side of the block 8 for suspending the wire, the distance counter transmits an electrical signal that starts the operation of suspending the wires with the block 8 for suspending the wire. The block 8. For hanging the wire of FIG. 9 and 10 has a suspension rod 63, rotating at its front end, producing up-and-down and side-turning movements, which are usually directed backwards in an inactive OT back-driven position. The horizontal and vertical movements of this rod, corresponding to movements of the hook 7 unit, are electrically detected by potentiometers 64 and 65. The U-shaped frame 49 is supported. With a rod in its middle part at one end of the suspension rod 63, and at its ends, supports vertical guide tubes 66. Each vertical guide tube 66 contains a coil with a compressive bar 67 fixed to the lower end by means of a head attached to the lower end of the guide tube felling. The upper part of the spring 67 supports the vertical shaft 50. 048 .. close to its middle part, the shaft being coaxial and guided by the guide tube 66. Two cylindrical roller mechanisms (Figs. 10 and 13) are supported while rotating by vertical shafts 50. Each These cylindrical roller mechanisms mainly include upper and lower cylindrical rollers 68-71 supported coaxially in the upper part of the shaft 50 and around the guide tube 66, respectively, and the method of their attachment ensures their independence its axial rotation. The guide rollers 45 and 46 for guiding the carrying cable are supported by rotating the frame 49 at points near their ends, while the direction of the rollers 47 and 48 for guiding the contact wire 15 are supported by rotating at the lower ends the corresponding vertical shafts 50 described cylindrical roller mechanisms. Suspension rod 63 can be rotated around its axis horizontally and vertically using hydraulic mechanisms with a piston and cylinder f or motors 72 and 73, to which hydraulic pressure is supplied by means of appropriate electro-hydraulic servo valves 7 to 75. To suspend two wires under high tension, in the order of 1 to 1.5 tons per hook 42, while they turn left-right and up-down through changes in the relative positions of the hook 76, which is already suspended point 60, and in the output part of the tension control unit 9, it is necessary to first place the carrying cable and the contact wire in the grooves of the guide rollers 45 and 46 and the guide rollers 47 and 48, respectively, and lift the wires so that the wire 14 rises to hook height 42. If this is explained in more detail, carrier cable 14 first rotates horizontally, causing the side surfaces of the cylindrical rollers 68 and 70 to come into contact and break the upper carrier cable 14 and contact wire 15. Then, since these rollers rotate when the wires 9 pass by in contact with them, the frame 49 rises, after which the carrying cable and the contact wire respectively fall into the grooves of the guide rollers 45 and 47. Since the guide roller 47 is supported during rotation at the lower end of the corresponding vertical shaft 50, which its upper end is supported by the upper cylindrical roller 68 during its rotation, the weight of the contact wire 14 is applied to the roller 47, the shaft 50 and the coil with a spring 67, which is thereby compressed. Consequently, the upper cylindrical roller 68 is lowered together with the shaft 50. The roller 68 is thus fully inserted into the guide tube 66 and lowered to a height that is lower than the guide roller 46, which receives the carrying cable 14 into its grooves and. rotates. In this way, contact between the hook 47 and the upper cylindrical roller 68 is prevented at the time when the suspension wire is suspended on the hook 42, whereby the work of hanging the wire on the hook is greatly facilitated. The carrier cable, which was thus raised to the height of the hook 42, is inserted through the opening, and therefore, into the bend of the hook 42 in the following manner. If the carrying cable 14 would have to be pulled out in the form of a straight wire arranged horizontally and parallel to the direction. By advancing, it would be difficult to place this wire in the bend of the hook. Accordingly (Fig. 14), two guide rollers 45 and 46 for supporting and guiding the carrying cable are positioned relative to each other in pitch or displacement with respect to each other. therefore, the supporting cable supported in this way has an oblique inclination in the direction of advancement. 04 10 That is, the guide rollers 45 and 46 are placed in mutually displaced angles with the help of a mechanism that biases at an oblique angle, and therefore the carrier cable is tilted with respect to the horizontal direction when viewed from the side and in the direction of the carriage. Using this mechanism, the carrying cable 14 enters the opening of the hook 42 as a natural result of the movement of the car, and this action is carried out normally even when there is some midpoint displacement in the part of the wire supported by the guide rollers 45 and 46 and the center of the hook. In the event that the hook 42 is positioned with a hole orientation that is 180 ° different from the orientation described above, the operator watching the hook confirms the direction of its hole and turns the switch 77 mounted on the described antenna lever 59 (Fig. 11). and 12) in order to cause the motor to rotate with the piston and cylinder 78 and thus position the guide rollers 45 and 46 in the positions indicated in Fig. 15, which are inverted with respect to the position shown on the fugue. 14, whereby the carrying cable 14 can be suspended as indicated above. Block 8 for hanging the wire. is supplied with rods 79 and 80, which are the links of the parallel four-rod linkage mechanisms supporting the inclination of the frame 49. With respect to the horizontal and vertical directions of movement of the car. Further, the block 9 for suspending the wire is supplied with suitable auxiliary units, such as limit switches 81 to 82, for controlling the working movements of the various parts.
