FIELD OF THE INVENTION

The invention relates to devices for mounting optical cables.

State of the art

Fiber optic cables are laid in outdoor conditions, in particular, by the air method by suspension on supports. Cables are suspended as self-supporting or attached to a supporting element - a cable, wire or self-supporting cable. Several methods of attachment are known, among them, such as attaching with clamps or ties located along the supporting element at certain intervals, attaching by winding cables to the supporting element with wire, cord or tape (the method is known as technology 1; · ΐ51ιίη§). attachment by winding a fiber optic cable onto a carrier element.

A known method of suspending a fiber optic cable on an overhead power line wire, in particular, on a lightning protection cable (US patent No. 4715582 dated 12/29/1987, Riga and E1ec1ps Co.), Including pre-winding a fiber-optic cable of measured length on a coil and then winding the fiber optic cable from the coil to the wire in a spiral using a special winding device - a winding machine. This method allows you to suspend a fiber-optic cable (coiled cable) in the span between two supports, winding it onto an existing supporting element, namely a wire or cable, and the maximum allowable tensile strength of the cable can be significantly less than for a self-supporting cable, and this gives the ability to significantly reduce the transverse dimensions and linear weight of the winding cable compared to self-supporting. When winding, in particular on a cable, the winding machine rolls on rollers while moving along the cable, periodically wraps the coil with a cable around the cable, and the cable, reeling from the coil, is spirally laid on the cable, being pulled by a special tensioning device of the winding machine. The cable on the reel must be balanced by the weight attached to the rod on the opposite side with respect to the axis of rotation, the weight of which is determined by the mass of the cable on the coil, the deviation of its center of gravity from the axis of rotation and the length of the rod. For winding, a special coiled fiber optic cable is used, the design of which has, as far as possible, the maximum reduced linear weight.

The method of attaching cables to the supporting element can also be applied to the task of constructing a PTTN air network (bbb, bf, bf, fiber to the house). RTTN networks have distribution cables to which drop-in couplings and drop-in cables are connected, which run from drop-couplings to subscriber houses (EB Gaskevich. Aerial RTTN-network for the private sector based on optical cable bundles. - Pervaya Milya Lav magazine ! M11e, No. 1, 2014). The number of houses connected to drop couplings is limited, for example, to 8, and one fiber passes from drop couplings to houses, in particular when using применении technology. In some cases, drop clutches are connected to the feeder part of the network star-shaped cables with a small number of fibers, for example containing up to 8 fibers. Cables intended for attachment to the supporting element and containing a small amount of fibers (from 1 to 8) can be thin, for example, have transverse dimensions up to 4 mm, and light, for example, have linear weight up to 10 kg / km. On the other hand, RTTN air networks are characterized by the fact that in the spans between supports located along the streets, several cables are simultaneously suspended, the length of each of which is limited to several hundred meters. Using navivny technology, it is possible to attach several thin distribution and drop cables to one supporting element, for example, to a strong self-supporting optical cable or to a cable, forming a dense bundle of optical cables suspended on supports. To do this, it is necessary several times to wind the winding machine along the same supporting element with cables already wound on it, each time winding another cable. A machine will not damage already wound optical cables if it, together with the cable reel, is light enough and if the supporting elements with which it rests on a carrier element do not pry up already wound cables and do not get entangled in them. In addition, the weight of the machine should allow one installer to install it on the supporting element and remove it manually from the ladder.

A known design of a winding machine (US patent No. 6032448 dated 03/07/2000, Rosav Ytyey), for which a coil with a cable is installed on the machine shaft, located on one side of the axis of rotation of the machine around the supporting element as it moves along it. The shaft is mounted on a rotating casing of the machine, which covers two rollers with which the machine rests on a supporting element. The cable is pulled by a separate device, which is made in the form of a bar with cable rollers, one of which can move along the bar, pulling the spring, and the coil has a braking mechanism, the braking force of which depends on the position of the movable roller. This type of winding machine is used for winding a cable with the number of fibers up to 72 onto lightning protection cables or phase wires of high-voltage power lines. In this case, the machine with the cable has a large weight, and it is installed on a wire or cable using a truck crane or a special lifting device. The design of the machine is well established for winding optical cables onto the wires of high voltage power lines. It was for this task that it was proposed. Coil

- 1,032366 of a machine of this design is far from the axis of rotation of the machine around the supporting element due to the fact that the housing on which the shaft is mounted covers the support rollers. For balancing, an extended rod and an increased balancing weight are required. Cable tensioning device increases the size of the machine and is not optimal in weight. All together, this makes it difficult to use this design to create an ETTN winding machine that allows multiple sequential winding of thin cables, namely, achieving compactness and low weight.

Another known winding machine (patent VI 2309109) has a frame inside which a cassette of two coils is mounted on which a piece of optical cable is wound with transitions between them. The rotation drive of the machine is made in the form of a separate unit, which is attached to the front wall of the frame. In the form of a separate unit, the rear support is also made, which is attached to the rear wall of the frame. The axis of the coils is perpendicular to the axis of rotation of the machine and is separated from it by a fairly small distance. This makes it possible to balance the machine with loads mounted on the frame without using a balancing bar. The machine rests on a supporting element with a front roller connected to the rotation transmission mechanism and a rear roller mounted on the frame in a bearing unit with bearings, which covers the bearing element and has a cutout for mounting on it. The bearings of the axis of the rear roller rotate freely in the support unit when the machine rotates in a plane perpendicular to the bearing element, and are not connected with the bearings of the axis of the front roller. After installation on the supporting element on the rear roller, a safety roller is installed from below so that both rollers cover the bearing element and hold the back of the machine on it at any tilt of the axis of the rear roller (floating, free position of the axes of the rear and safety rollers during rotation of the machine). To tension the cable, a special separate device is used, mounted on the rear wall of the machine frame. The design of the machine allows to reduce the aperture of its rotation and weight. However, the distribution of the cable across two coils creates the complexity of its winding on the coils. The frame covering the coils, a separate cable tensioner, the floating support of the rear and safety rollers create additional weight for the machine, and the rollers themselves do not provide for the use of the machine for winding onto a supporting element with already wound cables. This well-known design has been successfully applied to a winding machine with manual installation on a wire, designed for winding a thin cable onto high and medium voltage power lines, and is not intended to solve the problem of multiple sequential windings. This technical solution is the closest among those known to the proposed invention by a combination of features.

Disclosure of invention

The task was to develop a winding machine for multiple sequential winding onto the carrier element of fiber optic cables with low linear weight, and the weight of the machine with cable should allow it to be installed on the carrier element and removed from the carrier element manually by one installer. The machine should be such that when climbing the supports on stairs or in manholes, or when using an aerial platform, it could be installed manually on the supporting element and used for multiple sequential winding of optical cables, in particular, cables of ETTN aerial networks on supporting elements, in particular, on self-supporting optical cables and cables suspended on telecommunication poles, lighting poles, a contact network, low or medium voltage overhead power lines.

The technical result of the invention consists in the fact that technical solutions have been found for the knots of the winding machine, which can significantly reduce its weight and simplify working with it, while the machine makes it possible to sequentially wind several optical cables onto the carrier without the risk of damage to the already wound cables, forming an optical cable harness, the use of which increases the efficiency of construction, in particular, of ETTN air networks.

The technical result is achieved by the fact that the winding machine for winding a fiber optic cable onto a supporting element - a cable, wire or cable, with or without optical cables wound on it, comprising a frame, a coil for an optical cable with an axis fixed to the frame, a front roller supported on the supporting element and rolling along it when winding the cable, the rear support resting on the supporting element and covering it when winding the cable, a mechanical drive for converting the rotation of the front roller into the rotational movement of the frame machines around the load-bearing element when winding the cable, the device for cable tension when winding it, rollers for cable from the coil to the load-bearing element, a load designed to balance the weight of the cable with balance adjustment, stabilizing the load on the suspension attached to the non-rotating part of the mechanical rotation drive, differs the fact that the rear support is attached to the frame without the possibility of rotation relative to it and is made in the form of a detachable structure having at least two parts, one of which is rigidly attached to p ame, and the other is attached to the frame so that it can open the support for installing the machine on the supporting element and close with locking to cover the bearing element with or without cables wound around it in the form

- 2 032366 of the inner part of the ring surface, and the cable tensioning device in its entirety is located inside the reel drum.

If the rear support is rigidly attached to the frame, then it can be spaced with the front support roller to such a distance that the length of the frame allows you to position the coil on it between the rotation drive and the rear support and bring it closer to the supporting element as close as possible. In addition, a flat coil can be used. All together allows you to bring the center of mass of the cable closer to the axis of rotation of the machine when winding to a minimum distance and thus reduce the weight of the counterweight mounted on the rod from the side of the machine opposite the cable to balance it relative to the axis of rotation, or reduce the length of the rod. The cable tensioner is located in the reel drum and is a compact unit with a low weight. This design of the machine allows you to reduce the weight of the frame, the counterweight, the cable tensioning device, as well as the weight of the simplified rear support, since there is no need for a mechanism for rotating the rear support relative to the frame, and for mechanical linking of the rear support to the non-rotating part of the rotation drive. The rear support consists of at least two parts, one of which is diverted from the other, which allows you to install the machine on a supporting element or remove it from it. When closing the rear support of the machine mounted on the supporting element, the rear support covers it and holds the rotating frame of the machine in any position. The size of the hole in the buried rear support is such that a bundle in the form of a supporting element and cables previously wound on it can pass through it. Thus, a lightweight machine with a specific design of the rear support can allow another cable to be wound into a bundle without the risk of damage to already wound cables.

In one embodiment of the invention, a container is located inside the reel drum to accommodate the following elements, in whole or in part, in any combination: the inner end of the fiber optic cable bay, a branching device for single-fiber cables, single-fiber cables, optical connectors.

Such a container allows the use of a machine for winding into a bundle of single-fiber or multi-fiber cables terminated with connectors. This is important for creating ETTN networks, since it allows you to connect the fibers in many places without the use of fiber welding. For example, if the drop cable has connectors on both sides, and the drop clutch has an optical cross, then by connecting the drop cable through a detachable connection both in the drop clutch and the subscriber, there is no need to leave the optical mobile laboratory when the next subscriber is connected to the network .

In yet another possible implementation of the invention, the coil is non-removable, and the outer cheek of the coil is removable and enables the installation of a frameless cable bay on the coil.

This solution leads to significant savings when cutting the cable into separate sections - no separate coils for each bay are needed. Frameless coils should have a dense in-line cable laying, but this is necessary in any case if, when leaving the coil during winding, the cable is tensioned by the cable tensioning device located in the reel of the coil.

In another possible implementation of the invention, the rear support, made in the form of a detachable structure, when winding the cable covers the supporting element with cables wound on it or without cables wound on it with an annular surface that slides when winding the cable along the supporting element and, if any, other wound cables.

This is the simplest technical solution for the rear support, which allows you to reduce its weight. The inner part of the support can be made of plastic, for example, from caprolon or fluoroplastic. On the other hand, the supporting element is a self-supporting optical cable or cable and cables wound around it, as a rule, have a plastic sheath, in particular a polyethylene sheath. The coefficient of friction of plastic on plastic can be quite small, which makes this solution applicable in practice when creating optical bundles of the ETTN network.

In another possible implementation of the invention, the rear support, made in the form of a detachable structure, contains at least two rollers, the axes of which are rigidly fixed on the parts of the support and, when the support is closed on the bearing element, the axes are perpendicular to the bearing element, and the rollers are closed, while the rollers are shaped so that they cover the supporting element with or without cables wound around it like an annular surface and roll along it while winding the cable.

The rear support of this design allows the use of a winding machine for winding an optical cable, in particular, onto a metal cable or wire onto which other optical cables can already be wound. Friction on a metal cable or wire does not allow the use of a sliding rear support. The support rotates with the frame of the machine, and this simplifies its design and reduces its weight.

In another possible implementation of the invention, the parts of the winding machine rotating during winding around the supporting element are enclosed by a removable protective casing attached to the non-rotating part of the machine.

The protective cover allows optical cables to be wound onto a support element, which, for example, is surrounded by tree branches, pushing the branches apart and preventing them from falling into moving parts of the machine.

- 3 032366

The use of a protective casing is necessary, in particular, during the construction of BTTN air networks in southern cities in areas of old private buildings, where there are many green spaces on the streets. The diameter of the casing is determined by the dimensions of the coil or the length of the counterweight rod.

The implementation of the invention

One of the implementations of the invention, but this implementation is not limited, is a winding machine 1. It is intended, in particular, for multiple sequential winding of BTTN distribution and drop cables on a supporting element 2, in particular on a self-supporting optical cable with a polyethylene sheath or on a dielectric cable in a plastic shell. In front of the machine there is a rotation drive 5, the non-rotating body of which is closed by a casing 17. The rotation drive 5 converts the rotation using a gear mechanism

- 4 032366 of the front support roller 16 to rotate the frame of the machine 6. The front support roller 16 has a groove of such dimensions that when winding the next cable 4 to exclude the engagement of the already wound cables 3. The gear ratio is such that when moving the machine 35 cm along the supporting element 2 , frame 6, together with all the machine components attached to it, makes one revolution around the supporting element 2. To stabilize the non-rotating parts of the rotation drive 5, a suspension 14 with a stabilizing weight at the end is attached to its front housing. A rope 15 is hooked to the suspension 14, for which the machine 1 is manually pulled along the supporting element 2, winding the cable 4. The frame 6 is made in the form of a channel, the middle wall of which is close to the supporting element 2 when the machine 1 is installed on it at a minimum distance, which excludes the frame from touching 6 of the carrier 2 and cables previously wound thereon 3. At the rear end of the machine 1, the rear support 8 is rigidly fixed to the frame 6. The support 8 is in the closed state A when winding and covers the carrier 2 with cables 3 wound on it, and when installed cars n and the supporting element 2 or removal from it, in the open state B. For opening-closing, the reclining part 31 of the support is attached to the loop 32 to the fixed part 30, and the closed state is fixed by the lock 33.

In one embodiment of the invention, but not limited to this, the rear support 8 in closed condition forms an annular surface 34 around the carrier 2 with cables 3 wound thereon, which during winding slides along the carrier 2 and cables 3 wound thereon, holding the rear part of the frame is on it 6. The supporting element 2 and the wound cables 3 have, in particular, a sheath made of plastic, for example, polyethylene, and the ring surface is formed, in particular, by plastic parts of the rear support 8, for example, made of caprolon or toroplasta, and have a low coefficient of friction with the sheath material of the carrier element and the cable lock seam.

In another implementation of the invention, but not limited to this, the rear support 8 comprises two rollers 35, the axis of the first is fixed in a fixed part 30 of the rear support, and the second in the reclining part 31, the axes of the rollers being perpendicular to the supporting element 2 when installed on it machines 1. In the closed state A of the rear support 8, the rollers 35 are closed and their grooves form a circular hole with an annular surface 36 passing through the points of contact of the rollers, inside which passes the supporting element 2 with coiled cables 3. In front of the casa ia of the rollers, without blocking the holes, plastic inserts 37 are mounted, attached to the fixed part 30 of the rear support and, as it were, continuing the annular surface 36. The inserts 37 have a shape that allows filling the space in front of the places where the rollers 35 are clamped so that there are no winding cables 3 between the rollers 35 in the places of their contact, and during winding, the inserts 37 should not touch the supporting element 2. The inserts 37 prevent parts of the back support 8, in particular, rollers 35, from winding cables 3 from being wound onto the optical harness - the supporting element 2 with coiled cables 3. The annular surface 36 inside the hole formed by two closed rollers rolls longitudinally along the supporting element 2 and cables 3 wound thereon while winding another cable 4 and at the same time slides in the transverse direction due to rotation. The use of a rear support with rollers is necessary with a large coefficient of friction of the sliding support against the supporting element, for example, if optical cables are wound onto an aluminum wire or steel cable. In another embodiment of the rear support with rollers, the number of rollers is more than two.

On the frame 6 of the winding machine, in addition to the rear support, there are placed rollers 9 for cable routing from the coil 7 to the supporting element 2, a cone for releasing the cable 10, the axis 18 of the coil for the cable and the counterweight rod 13. A fixed load 11 is fixed to the counterweight rod 13, and to it additional removable loads 12 are attached, the quantity and weight of which is determined depending on the amount of cable in the bay 21 on the coil 7.

The outer cheek 19 of the coil 7 is removable. This allows you to install on the coil frameless bay 21 coiled optical cable, which is fastened, for example, with plastic clamps. After installing the bay 21 on the drum 23 of the coil, the inner end of the bay with an optical connector (s) 22 is placed in a container 24 for accommodating optical connectors located inside the drum 23 of the coil. The bay 21 is pressed by a removable cheek 19, which is fixed with a nut 20, and the plastic clamps on the bay 21 are cut and removed. The outer end of the coil 21 of the winded cable 4, which can also be terminated with connectors, is carried out in the rollers 9, released through the cone 10 onto the supporting element and attached to it at the beginning of the span. Stretching the winding machine 1 along the supporting element 2 along the span, carry out the winding of the cable 4.

In the process of winding the cable 4 is tensioned by a tension device 25, which is located inside the drum 23 of the coil. The tension device includes a brake drum 26 attached to the drum 23 of the coil, brake pads 27 to which the outer end of the coil spring 28 is attached. The inner end of the coil spring 28 is mounted on a freewheel 29 located on the axis 18 of the coil. At the beginning of the winding process, the spiral spring twists and gains potential energy, providing a certain moment of force acting on the coil 7, and thereby the spring 28 through the coil 7 pulls the cable 4 during winding. Then, with

- 5 032366 a certain amount of winding of the spring 28, the brake pads 27 begin to slip on the brake drum 26 and continue to slip until the winding machine 1 stops. During movement, the coil 7 pulls the cable 4. When the machine 1 stops, the coil 7 also pulls the cable 4. The tension remains when the machine 1 rolls back, such that the spring 28 is still in tension. The tension of the cable 4 by the spring 28 through the coil 7 is acceptable if the cable 4 is laid in the bay 21 in the form of a dense in-line layout, eliminating the failure of the cable 4 between the turns of the bay 21 when it is tensioned. The overrunning clutch 29 does not allow the spring 28 to be unwound by rotation of the coil 7 in the direction opposite to the winding of the cable 4 and protects the spring 28 from breaking.

For another implementation of the invention, but not limited to this, a protective casing 38 is used, which is worn on the winding machine 1 and attached to the non-rotating casing 17 of the rotation drive. The casing 38 covers the rotating parts of the machine 1, such as a coil 7 with a cable reel 21, a rod 13 with counterweights 11 and 12, and a frame with other elements located on it. The diameter of the casing 38 is determined by the size of the coil 7 or the length of the rod 13 of the counterweight. For one of the implementations of the invention, the center of gravity of the coil 7 with the cable bay 21 is located close enough to the axis of rotation of the frame 6 of the machine 1, and the rod 13 can be made so short that the diameter of the casing 38 will be determined only by the dimensions of the coil 7. The casing 38 has a longitudinal slot 39 for the possibility of installation on the supporting element 2 of the machine 1 with the casing 38 put on it. The casing 38 protects, for example, from the branches of the trees 40 the rotating parts of the machine 1 while winding onto the supporting elements suspended in the spans between the supports in the streets where there are a lot of overgrown green plantings.

In one implementation of the invention, but not limited to this, the winding machine 1 is designed for winding distribution cables with up to 8 fibers and single-drop RTTN network cables. Both distribution and drop cables have transverse dimensions of 2 mm by 4 mm and linear weight of 8 kg / km. Cables are terminated by connectors on both sides. The maximum recommended drop cable length is 150 m. The winding machine with a 150 m cable weighs 7.5 kg. The maximum cable bay length that can be installed on the machine is 350 m. Long lengths are used for distribution cable. At the same time, a machine with a cable bay 350 m long and added counterweight weights weighs 10.5 kg. An aluminum protective casing with a diameter of 40 cm weighs 3 kg. This weight of the machine with the cable allows one installer to manually install it on the supporting element from the aerial platform basket or from the stairs. The light weight of the machine does not pose a threat of damage to already wound cables during multiple windings, and the design of the front roller and rear support prevents their engagement with the machine and tangling in parts of the machine.
