Description

The invention relates to the field of laying fiber optic cable (FOC) overhead power lines (VL power lines) and, in particular, to methods and devices for winding it onto a carrier wire (phase wire or lightning cable) overhead power lines (VL power lines).

The technical result of the invention is to create a device that provides reliable and fast fastening of the wok on the phase wire or ground wire of the overhead power line.

From the patent literature there is known a method for winding an FOC on an overhead power line wire (OHL transmission line) [DE 3228239 patent] using a winding machine (HM) on which a wok coil is located. The winding machine (NM) is moved along the overhead power line wire. In this case, the coil rotates around the wire, describing a spiral path.

This method and device for implementing a wok winding on a high voltage power line wire has a large weight, complex structure and large dimensions. This complicates the installation of the device on the overhead power line wire and complicates the method of winding the fiber optic cable.

There is also a method of winding a fiber optic cable onto a current-carrying wire of a power transmission line, as set forth in GB patent No. 2180666 of 04/01/1987.

The disadvantages of this method are the need for the supports and insulators to be dismantled and mounted on a winding machine (long, laborious, cyclically repeatedly repeated, performed at a height in difficult conditions) and low precision of NM balancing, carried out using a probe sliding on the upper wok layer on the coil NM, or the complete absence of a balancing device. This causes a dangerous wobble of the winding machine (NM) by centrifugal forces from the rotation of an unbalanced coil with a cable, the quantity and weight of which changes during the operation of the NM and, thereby, limits the speed of laying (movement of the winding machine through the wire).

The closest technical solution to the proposed invention is a method and device for winding a fiber optic cable onto an electric wire [Н65Р 81/08, application No. 2006101965/12 from 2006.01]. The device comprises a trolley and a rotating frame (rotor) connected by a rotation mechanism. A cable drum is mounted on the frame. To maintain the desired tension of the wok, wound on the electric wire, a tensioner is used. To prevent the cart from rotating around the carrier wire, a balancer is used.

The disadvantage of this device and the method of winding fiber optic cable is the complex mechanism of rotation of the frame and the tensioner device, as well as the presence of a dimensional balancer with a special device.

In addition, this device must be dismantled and then reassembled for each power transmission tower to pass in places of wire suspension to power transmission towers through insulators.

The technical task of the invention is the creation of a simple and reliable method of winding a wok on a carrier wire (phase wire or ground wire) and ensuring wound wok on the suspension of the carrier wire to the supports on the insulators without dismantling the winding device and removing it from the carrier wire.

At the same time, the winding device has a mechanism and devices for suspending it under the carrier wire and moving the device along the carrier wire on auxiliary wheels under the insulator.

The specified technical problem is solved as follows: the winding device with the help of auxiliary and main wheels having a gutter-shaped rim is mounted on a supporting wire, the main wheels being rigidly fixed on the basis of the winding device, and auxiliary wheels are mounted on brackets to clamp them to the supporting wire using horizontal hinges, in addition, on the brackets to the base they attach a rod with a platform at its lower end. An electric generator is placed at the end of this rod. On the base, an electric motor for driving the main wheels, an electric motor for moving auxiliary wheels and rotating the carriage are mounted on which a cable drum with a wok and a guide with a balancing weight are fixed, and the carriage is rotated on the base, and a longitudinal through groove is made on the carriage and the base, through which the carrier wire is placed along the longitudinal axis of the base and the carriage inside them, then attach the end of the wok to the support, press the auxiliary wheels to the supporting wire. After that, the winding device is moved along the supporting wire with the help of an electric drive, while rotating the carriage with the wok cable drum, wound it, and in front of the insulator, the front auxiliary wheel is lowered below the insulator and the winding device is advanced until the auxiliary wheel is moved beyond the insulator, then this auxiliary wheel fixed with an adjustable length tie rod on the carrier wire and rotate the winding device around the axis of the carrier wire 180 °, then turn the carriage is opened, placing its groove vertically in its upper position, after which the winding device is lowered down and installed under the support wire on the auxiliary wheels, then the winding device is moved on the auxiliary wheels under the cable until the rear auxiliary wheel reaches the insulator, after which the winding device is installed behind the insulator on the supporting wire in the reverse order and after lowering the rear auxiliary wheel below the insulator, the winding device is moved forward and behind the insulator m, the rear auxiliary wheel is fixed on the carrier wire, after which they are laid behind the wok insulator and continue to winding (laying), moving the winding device forward and rotating the carriage around the carrier wire, and when the next support with the insulator is reached, the wok is wound in the same way.

The proposed method of winding the wok on the supporting wire is illustrated by the following drawings:

In FIG. 15 shows a view of the carriage on the left in a plane perpendicular to the electric wire (section AA in FIG. 8). Here the bar with the balancing weight is located horizontally.

In FIG. 16 shows the same view when the carriage is rotated through an angle of 45 °.

In FIG. 17, the same view of the carriage is given, but the groove of the carriage is vertical, the electrical wire has come out of the groove and is above the carriage.

In FIG. 18 shows the installation of a device for implementing the claimed method of winding a wok.

In FIG. 19, the device is mounted on a carrier wire.

In FIG. 20, a wok winding method is shown in action - to implement the proposed method, a device is created for wok winding on an electric wire (ground wire or phase electric wire).

The device consists of a base 1 - a carrier pipe with a through longitudinal groove 2, the width of which is greater than the diameter of the carrier wire, in its lower part for passing the carrier wire 3 through it (placing the wire inside or outside the device when installing the device on the wire and passing supports with insulators) .

At the ends of the base pipe 1, brackets, a front bracket 4 and a rear bracket 5 are rigidly fixed from above (FIG. 1). On the brackets installed front and rear main wheels 6 with a grooved rim and an electric motor 7 for their drive. And also in the bearings installed shaft 8 of the gear drive 9 of the rotation of the carriage 10.

In addition, on the front bracket 4, a vertical rod 12 is pivotally mounted using a hinge 11, at the end of which a horizontal platform 13 with an electric generator 14 fixed to it is fixed.

On the bracket 4, in addition, the front auxiliary wheel 15 is pivotally mounted, made movable in a vertical plane using two rods. Moving it in the vertical plane provides a sliding rod 16 having an internal electric drive (actuator). The traction length is controlled by a ground operator using a remote control or an automatic software device (microprocessor device). The rod 17 of a fixed length provides a predetermined trajectory of the wheel. On the axis of the rear bracket 5 of the base 1, the rear main wheel 6, the electric motor 7 for its drive and the auxiliary rear wheel 18 are installed. The rear auxiliary wheel is pivotally mounted on the rear bracket 5 using two rods 17 (fixed length) and a sliding rod (actuator) 16 ( controlled by an operator or microprocessor).

On the middle part of the base 1 (pipes with a groove), a carriage 10 is installed, which rotates on a cylindrical base on sliding bearings 19, which are located on the front 20 and rear 21 walls of the carriage. The carriage 10 has a frame 22, which provides it with rigidity. The front and rear walls, fixed at the ends of the frame, provide it with strength and reduce the weight of the carriage. The walls of the carriage and its frame have a longitudinal groove, the width of which is greater than the diameter of the carrier wire, which communicates with the groove of the base when the carriage is rotated through 180 °. Through these grooves, the carrier wire is passed through the groove of the base and placed along the axis of the base when installing the winding device on the carrier wire and when passing insulators of supports.

On the front wall 20 of the carriage, the gear 23 is rigidly fixed with a groove coinciding with the groove of this wall. The carriage is driven in rotation from an electric motor mounted on the front wheel bracket through a drive shaft 8 and a pair of pinion gears 9 connected to this shaft and a chain 34.

Racks 25 are fixed on the carriage frame 22, on which a cable drum 26 with a wok is mounted on an easily removable axis 27, which ensures quick removal of an empty drum and quick and easy installation of a drum filled with wok.

On one longitudinal line with racks 25, perpendicular to the longitudinal axis of the device and the carrying wire, a guide 28 is installed on the opposite side of the carriage with a balancer (balancing the variable mass of the cable drum with the wok) load 29, which moves along the guide 28 with a screw pair or chain connected to balancing weight 29.

On the lower part of the carriage in front of the drum with the wok on the bracket 30 mounted on the frame of the carriage, a guide device 31 for supplying and stacking the wok on a carrier wire with a tensioner 32 and a brake wheel 33 is installed.

The brake wheel 33 and the device for feeding and stacking the wok to the supporting drive are kinematically connected using a chain gear 34 with the mechanism for moving the balancing weight 29 along the guide 28, which ensures that the center of gravity of the device for laying the wok along the axis of rotation on the carrier wire is maintained. This eliminates the vibration and swaying of the moving wok styling device, the vibrations of the carrier wire and simplifies the movement of the winding device through the insulator 35.

The method of winding a fiber optic cable onto a carrier wire is as follows. Before starting work, a cable drum 26 with a wok is installed on the winding device, an electric generator 14 is turned on, as well as a remote control panel. The wok 36 is laid through the guide device 31, and then the end of the wok cable is fixed to the power line support or to the carrier wire with a clamp (not shown). After preparation, the winding device is installed on the main wire 3 on the main wheels 6 and, with a command from the control panel, the operator presses (with linear actuators-actuators connected to the electric generator) auxiliary (15 and 18) wheels to the main wire. Then, the operator from the control panel includes the “winding” process, which ensures the movement of the winding device along the carrier wire using the electric drive of the front main wheel while rotating the carriage with the wok cable drum, they are wound (Fig. 1, 4, 5, 20) onto the carrier the wire. In front of the insulator mounting the carrier wire to the power line support, the front auxiliary wheel is lowered below the insulator (Fig. 5) and the winding device is moved forward until the auxiliary wheel moves beyond the insulator (Fig. 6). Then this auxiliary wheel is fixed (pressed to the wire) with the help of a sliding rod of adjustable length 16 (linear actuator-actuator) and the winding device is rotated 180 ° around the axis of the wire (Figs. 7 and 8). Then the carriage is rotated, placing its longitudinal groove vertically in its upper position, after which the winding device on the auxiliary wheels is lowered down below the insulators (Fig. 9). Then, the winding device is moved upside down on the auxiliary wheels under the insulator until the rear auxiliary wheel reaches the insulator (Fig. 10). Then install (turn over to its original position) the winding device behind the insulator on the supporting wire in the reverse order (Fig. 11 and 12). After lowering the rear auxiliary wheel below the insulator (Fig. 13), the winding device is moved forward and the rear auxiliary wheel is fixed (pressed) on the carrier wire (Fig. 14). Then they lay the wok behind the insulator and continue winding it, moving the winding device forward, rotating the carriage around the carrier wire, and upon reaching the next power line support with the insulator, repeat the above operations of passing the support with the insulator in the same way.

In FIG. 15 shows the position of the carrier wire in the carriage along the axis of the housing 1. It is shown in a plane perpendicular to the carrier wire and the axis of the winding device along which it moves and around which the carriage with a cable drum with a wok rotates.

In FIG. 16, the same is shown in an intermediate position when the carriage is rotated 45 °. The carrier wire is located along the axis of the carriage.

In FIG. 17 shows the position of the winding device located on the supporting wire on the auxiliary wheels. The carrier wire exited through the groove of the base of the carriage. The carriage sank below the carrier wire.

Compared with the known methods of winding the wok, the proposed method provides an increase in the speed of winding on the supporting wire, because the passage of the power transmission line support (suspension insulator) is the most labor-intensive and time-consuming operation, increases labor productivity and safety when woking the wok and its quality.

The proposed method also reduces the cost of the winding device and its maintenance, simplifies the design and weight.

This is provided by the distinguishing features of the proposed invention.
