Definitions

  • Fiber optic cable winding machine 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.
  • a supporting element - a cable, wire or self-supporting cable.
  • Several methods of attachment are known, among them, for example, attaching with clamps or ties located along the carrier at regular intervals, attaching by winding cables to the carrier with wire, cord or tape (the method is known as “lashing” technology), attaching by fiber optical cable to the supporting element.
  • a known method of suspending a fiber optic cable on an overhead power line wire, in particular on a lightning protection cable including pre-winding a measured fiber-optic cable of length to a coil and then winding fiber-optic cable from coil to 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.
  • 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 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 length rods.
  • a special coiled fiber optic cable is used, the design of which has, as far as possible, the maximum reduced linear weight.
  • FTTH networks have distribution cables to which drop couplings are connected, and drop cables that run from drop couplings to subscriber houses (E. Gaskevich, Aerial FTTH network for the private sector based on optical cable bundles. - FIRST MILA magazine Last Mile ", JV2 I, 2014).
  • the number of houses connected to drop clutches is limited, for example, to 8, and one fiber passes from drop clutches to houses, in particular when using PON technology.
  • 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 can be thin, for example, have transverse dimensions up to 4 mm, and light, for example, have linear weight up to 10 kg / km.
  • FTTH air networks on the other hand
  • 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.
  • the weight of the machine should allow one installer to install it on the supporting element and remove it manually from the ladder.
  • a design of a winding machine is known (U.S. Pat.
  • 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 rollers for cable, one of which can move along the bar, pulling the spring, and the coil has a brake 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.
  • 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 wires
  • the machine coil 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 FTTH winding machine that allows multiple sequential winding of thin cables, namely, achieving compactness and low weight.
  • Patent RU 2309109 Another well-known winding machine (Patent RU 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 implemented as a separate unit, which is attached to the front wall of the frame.
  • 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 gives
  • 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.
  • a safety 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", the free position of the axes of the rear and safety rollers during rotation of the machine).
  • 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 in two coils creates the complexity of its winding on coils.
  • 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 must be such that when climbing stairs or in manholes, or when using an aerial platform, it can be installed manually on a carrier and used for multiple sequential winding of optical cables, in particular FTTH aerial cables onto carrier 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 utility model 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, FTTH aerial networks.

  • the composition is inside the drum reel. 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.
  • 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.
