Description

Armored car

The utility model relates to the field of cable industry, in particular, to devices for applying armor from steel wire to a cable, in particular, to an optical fiber cable.

Known armor mapping, containing a transfer device with a supply of armored cable, which serves as the central element of the twist, and transfer devices with a supply of armor wire, a torsion mechanism, from the output of which the cable is pulled by a traction unit to a receiving device (Babischsiy O.Sh., Lehtman L.Ya . "Technology of cable twisting, Moscow, Energy, 1978, S. 15, 33). In this machine, a half-cot serves as a dispensing device, in which a drum with an armored or shielded cable is installed. The giving half-cradle rotates synchronously with the traction and receiving devices. The armored wires unwound from the stationary giving devices, through the distribution socket, are brought to the cable, onto which they are wound due to the rotation of the latter around its axis.

A disadvantage of the known machine is its significant dimensions and weight, the need for large production areas and a reinforced foundation, as well as large energy costs, because the work of the machine is associated with

MKI7N01V13 / 22

the movement of significant mass coils with armored wire, therefore, such machines are placed exclusively on the first (and basement) floors of industrial buildings, heavy labor costs in the production of armored cable, since preliminary rewinding of the armor wire from the bays (on which it is supplied by the manufacturer) to is required. To ensure the smooth operation of the machine requires at least two operators.

The objective of this utility model is to simplify the process of applying the armor to the cable, reducing the weight of the machine and the required production space, the ability to install a reservation machine without reinforcing the foundation (i.e., not only on the ground or basement floors), as well as increasing productivity .

- the crimp assembly is made in V1ade of the crimp sleeve or at least two installed rollers onno3trrHO, between which a passage for the armored cable is formed;

- at the entrance to the guiding device, a rectifying device is installed, made in the form of a series of straightening rollers arranged in maxAiaTHOM order (with overlapping their working surfaces), between which a zigzag-shaped passage is formed for the armor wire enveloping the mentioned roller surfaces.

An information search carried out by the applicant showed that a broaching machine for armor protection is unknown from the prior art.

cable with steel wires, containing a torsion mechanism in the form of a device providing multidirectional SZ-twisting around a cable of armor steel wires passing for this through sockets of a torsion mechanism, which are rotatably mounted and kinematically connected to their rotation drives around the armored cable, and at the torsion output the mechanism is installed introduced H1geobmotchik, providing crosswise threading on the aforementioned SZ-twist, which allows us to conclude that the declared The proposed technical solution to the patentability criterion is “novelty and makes it possible to qualify the mentioned solution as a“ utility model.

The reservation machine, made according to the claimed utility model, contains a donating device I installed sequentially along the direction of the cable and wires along with a supply of armored cable 2, giving devices 3 with a supply of brooches of steel wire 4, while the number of wires is determined by the design of the armored cable cover. Giving devices 3 are designed to supply steel wire 4, which is pulled together without preliminary rewinding (on coils) directly from the bays 5 upwards, passes through a system located in

in a checkerboard pattern of horizontal and 1 or vertical straight lines 5 through 11 of the rollers 6, which form the basis of the rectifier device, and which provide QQ tension, and goes to the guide device 7. The straightener rollers (Fig. 6) are arranged with a cross chain so that a zigzag passage is formed between them, the axis of which lounggg in the same plane, and which is designed to accommodate and advance on it steel armor wire.

The guide device 7 is designed for the orderly introduction of wires 4, forming the armor of the cable 2, into sockets 8 of the SZ twist assembly. If necessary, change the direction of movement of the wire on the device mounted rotary rollers (not shown). The wires 4 coming at different angles to cable 2 with a guide device made in the form of a rack 10 with orienting (guides, rotary) rods 9 mounted on the rack so that their centers are located around the circumference around the core-cable 2 (the center of the mentioned circle lies on the geometric axis of the central element of the twist-cable 2) and are inserted into sockets 8 of the twisting mechanism (made in the form of an SZ-twisting device) at the same distance from the core.

The SZ-twisting device (Fig. 4) will allow for the implementation of multidirectional steel wires 4 around the core of the armored cable 2. The basic kinematic diagram of such a device is known, for example, from the aforementioned information source (pp. 49-54). Twisting in such a device is performed using a system of sockets 8 that rotate around a cable with different rear speeds, and as a result close the armor wire in one angular direction and then in the opposite direction. The number of outlets, the distance between them, the angle of rotation depend on the design of the armored cable. Sockets 8 can be made with plug-in (in particular removable) bushings AND (Fig. 5) of a wear-resistant material, for example, based on hard alloy or ceramic.

The thread wrapper 12 (Fig.6) for fixing received. The twisting fixation occurs after crimping the armor protection wires of the cable (s) and the central element with horizontal and / or vertical rollers (not shown) installed in pairs opposite, or with a crimp sleeve 13 of the crimp assembly (Fig. 7) and winding with a thread 14 (f11g) in this position .6). The basic construction of the thread wrapper is known from the aforementioned information source (p. 92, 93). So that the thread during winding does not touch the elements of the crimp assembly, before Ш1м

additionally set the enclosing ring 15 (Fig.7). Mentioned ring 15 can be structurally performed in conjunction with a crimp sleeve 13.

Traction device 16 is used to pull the cable at a predetermined speed between all functional devices and machine components. The basic design of the traction device is also known from the aforementioned information source (p. 54).

The receiving device serves to form an ordered supply of armored cable, which is achieved, for example, by winding the produced cable onto a drum (not shown). An armored cable to a device providing a coating of an armored cable with a waterproofing coating, mainly based on plastics (not shown).

The reservation machine, made in accordance with the claimed utility model, operates as follows. The reserves of the armored cable (usually on) and the armor of the lower steel wires 4 (the latter can be both on the coils and in the bays on which they are supplied from the factory, which is more general), are installed in the transfer device and the free ends of the wires are inserted between straightening and guiding them with rollers, into holes of sockets, between crimping rollers

They also conduct the end of the cable, circle the bundle of wires and cable of the thread of the thread wrapper, and then thread the connected cable and wires between the pulling belts of the traction device. The propeller mechanism and other functional devices are preliminarily regulated by setting the necessary process parameters, depending on the corresponding parameters of the cable and wires used. After starting the machine, the twisting process is carried out in automatic mode, at the output an ordered supply of armored cable is formed. The machine is reliable in operation, easy to maintain and does not require high qualification of a service operator. In addition, the machine has small (compared to the prototype) weight and dimensions, and its work is not accompanied by high vibrations.

Thus, the implementation of the utility model reduces the laboriousness of applying the armor to the cable, while, since the weight of the machine and vibration are reduced during operation, the production room for such a machine can be formed on any (including upper) floors of buildings in which In this case, special floors are not required, while cable production productivity is increased.
