Description

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

From the patent literature it is known a device for winding a wok on an overhead power line wire (OHL transmission line) [DE 3228239 patent], using a winding machine (HM) equipped with a wok coil. A winding machine (NM) is installed on the wire and moves along the overhead power line wires. In this case, the coil rotates around the wire, describing a spiral path.

This device for implementing a wok winding on a high voltage power line wire has a large weight, complex structure and large dimensions. The main disadvantage of this winding machine is the high complexity and the complexity of transferring it through the fastening of the wire to the support insulator of the overhead power line. This operation is performed at altitude, in any, including hot and cold weather.

It is also known a device for winding a wok on a current-carrying wire, set forth in GB patent No. 2180666 of 04/01/1987

The disadvantages of this device are the need for passing supports and insulators for dismantling and mounting the winding machine (long, laborious, cyclically repeatedly repeated, performed at height in difficult conditions, including heat and cold, operation) and low accuracy of NM balancing, carried out approximately using a probe, sliding on the upper layer of the wok on the coil NM, or the complete absence of a balancing device. This causes a dangerous swinging of the winding machine (NM) by centrifugal forces from 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 and quality of laying (the movement of the winding machine through the wire and the stability of the tension of the winded optical cable) .

The closest technical solution to the present invention is a device for winding a fiber optic cable onto an electric wire [patent RU 2309109 class. C1 from 10.27.2007]. 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 electrical wire, use a tensioner. To prevent the trolley from rotating around the carrier wire and giving it a vertical position, use a balancer.

The disadvantages of this device for 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. This is a dangerous labor-intensive, long-term manual operation performed at altitude, including in hot and cold weather.

The technical task of the invention is the creation of an easy-to-use and reliable high-performance device for winding a wok on a carrier wire (phase wire or ground wire) and for ensuring wrap of a wok in places where the carrier wire is suspended to supports on insulators without mounting-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 is installed on the supporting wire using auxiliary and main wheels with a gutter-shaped rim, the main wheels being rigidly fixed to the base of the winding device, and the auxiliary wheels are mounted on brackets for clamping them to the supporting wire using horizontal hinges in addition, a rod is installed on the brackets of the base with an electric generator or accumulator located at its end, and, on the base, electric motors are installed a drive for driving the main wheels, an electric motor for mixing the auxiliary wheels and the rotation of the carriage, on which a cable drum with a wok and a guide with a balancing weight is fixed, an electric switch connecting the generator and a battery with a radio control or microprocessor device mounted on the device, as well as an approaching support sensor with an insulator, moreover, the carriage is made rotating on the base, and a longitudinal through groove is made on the carriage and on the base, through which the carrier wire is installed along the longitudinal axis of the base and the carriage inside them, besides an end fixed to an anchorage FOC transmission line before winding the wire on the carrier FO.

The proposed device for winding the wok on the supporting wire is illustrated by the following figures and drawings:

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

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

The device for winding a wok onto a supporting wire consists of a base 1-carrying pipe with a through longitudinal groove 2, the width of which is greater than the diameter of the carrying wire 3 for 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 are rigidly fixed from above. The front bracket 4 and the rear bracket 5 (Fig. 1). On the brackets are installed front and rear main wheels 6 with a grooved rim and an electric motor 7 for their drive. And also, in the bearings there is a shaft 8 of the gear drive 9 of the carriage 10 drive.

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 a vertical plane provides a slider 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, a fixed length, provides a given 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 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 turned 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 driving gears 9 connected to this shaft and to each other by 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 of a filled wok.

In one longitudinal line with the uprights 25, perpendicular to the longitudinal axis of the device and the carrier wire, on the opposite side of the carriage, a guide 28 is installed with a balancing weight 29 (which balances the variable mass of the cable reel with the wok). This balancing weight is moved along the guide 28 by a screw pair or chain connected to the balancing weight 29.

On the bottom 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 on a fixed drive are kinematically connected using a chain gear 34 with a 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 36 along the axis of rotation on the carrier wire is maintained. This eliminates the vibration and swaying of the moving wok laying device, eliminates jerk tension wok of the carrier wire, and simplifies the movement of the winding device through the insulator 35.

A device for winding a fiber optic cable onto a carrier wire operates 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, then the end of the wok cable is fixed to the power transmission 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 electric drives - actuators connected to the electric generator) auxiliary (15 and 18) wheels to the main wire. Then the operator from the control panel starts the “winding” process, which ensures the movement of the winding device along the carrier wire using the electric drive of the front main wheel with simultaneous rotation of the carriage with the wok cable drum, it is 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 electric 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 behind the insulator 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 and at the same time rotating the carriage around the carrier wire, and when the next power line support with the insulator is reached, the above operations of passing the support with the insulator are repeated 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 the 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 reel 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 pore soy carriage.

In FIG. 17 shows the position of the winding device located on the carrier 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 wok winding devices, the proposed device provides a several-fold increase in the speed of winding onto 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 device allows to reduce the cost of winding equipment and its maintenance, simplifies the design and weight.

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