Description

 The invention relates to electrical engineering, in particular to methods for laying cables (wires) for various purposes in a conduit device, and can be used in industrial, administrative and residential buildings.

 A known method of laying a cable (wire), including the manufacture of a material body (duct) with internal cavities and laying of a cable (wire) or several cables (wires) in the internal cavity (patent N 2066510, application N 94005497 from 1994, Russia, N 02 G 3/04) - analogue.

 There is also a method of laying a cable (wire) in a conduit device, according to which a pulling force (load) is applied to the cable and subsequent placement of the cable (wire) in the conduit pipe channel (patent N 2128389, application N 93046285 from 1993, Russia, H 02 G 3/04) - prototype.

 The known technical solution makes it difficult to lay several cables (wires) in one cavity (pipe) of the conduit device and has an increased material consumption. This is because with the known method of laying cables (wires), they do not effectively occupy the volume of the internal cavity of the pipe of the conduit device and interfere with each other when laying them. The conduit device pipes are made monolithic and they do not facilitate the laying of cables (wires).

 The problem to which the claimed technical solution is directed is to expand the arsenal of technical means for laying cable (wire) in a conduit device.

 The technical result that can be obtained by carrying out the invention is to expand the arsenal of technical means for methods of laying a cable (wire) in a conduit device.

 The essence of the proposed technical solution lies in the fact that in the method of laying the cable (wire) in the conduit device, including the application and subsequent placement of the cable (wire) in the conduit pipe channel, according to the method, the conduit pipe is made in the form of a perforated body with holes. After placing the cable (wire) in the channel, it is fixed relative to the channel, and fixing is carried out by first placing the cable (wire) in the area of the holes, extruding individual parts of the cable (wire) from the area of the holes outside the channel of the conduit pipe and then fixing them on the surface of the conduit pipe outside the channel. To extrude individual parts of the cable (wire) from the area of the holes, use devices (tools), which are inserted through the holes (perforations) of the cable pipe. As devices (tools) using known tools that have a cavity to capture the material body (wrench, hook, etc.), as well as devices (tools) that can be used as a pusher (screwdriver, jumper, chisel and etc.). The size of the device (tool) used must be smaller than the size of the holes (perforations) made on the surface of the conduit pipe. The extruded, individual parts of the cable (wire) are fixed from the hole zone by means of material bodies of arbitrary geometric shape with clamps, the cable (wire) being pre-fixed with a clamp, and then the material body is laid between the cable (wire) and the outer surface of the conduit pipe. The clamp is made in the form of a spring plate, one end of which is rigidly attached to the material body, for example, by welding, fasteners, etc. As a material body, material bodies of regular and irregular geometric shapes (rod, tube, etc.) are used .

 It is the manufacture of the conduit pipe in the form of a perforated body with holes and the fixing of the cable (wire) relative to the surface of the conduit pipe provides a solution to the problem and a new technical result.

Comparative analysis with the prototype shows that the claimed technical solution has common features with the prototype:
apply a load to the cable (wire);
place the cable (wire) in the conduit pipe channel.

The proposed technical solution differs from the prototype with new features:
conduit pipe is made in the form of a perforated body with holes;
after placing the cable (wire) in the channel, fix it relative to the surface of the channel;
fixing is carried out by pre-placing the cable (wire) in the area of the holes;
squeezing individual parts of the cable (wire) from the area of the holes outside the channel conduit pipe
fix extruded parts of the cable (wire) on the surface of the conduit pipe outside the channel;
for extrusion of individual parts of the cable (wire) from the zone of the holes, devices (tool) are used, which are inserted through the holes (perforations) of the conduit pipe;
carry out the fixation of extruded, individual parts of the cable (wire), from the zone of the holes by means of material bodies of arbitrary geometric shape with clamps;
the cable (wire) is pre-fixed with a clamp, and then the material body is laid between the cable (wire) and the outer surface of the conduit pipe.

 From the above list of features and the achievement of the task, it is clearly seen that the claimed technical solution is a new combination of features, as a combination of known and new features, providing a new technical result, unknown at the filing date of the application. A new technical result that can be obtained by carrying out the invention is to expand the arsenal of technical means for laying cable (wire) in a conduit device.

 A new set of features of the proposed technical solution is essential, because they are all necessary and sufficient to obtain a new technical result. The signs mentioned above are significant for the simple reason that there is a causal link between the signs and the resulting technical result.

 The proposed solution is industrially applicable, because it can be used in construction, industry, agriculture and other sectors of the economy.

 The proposed technical solution also meets the criterion of "novelty", because it is not known from the prior art. Not known from the prior art, the set of essential features of the claimed technical solution and their impact on obtaining the desired technical result.

 The claimed technical solution meets the criterion of "inventive step", because no solutions have been identified that have features that match its distinctive features and not known fame of the distinctive features on the resulting technical result.

 Thus, the claimed technical solution meets the criteria for the invention, and provides a new technical result.

 In FIG. 1 shows a method of laying a cable (wire) in a conduit device; in FIG. 2 is a plan view of FIG. 1.

 The conduit pipe is made in the form of a perforated body from separate parallel and mutually intersecting threads 1 (see Figs. 1 and 2) with holes 2. The holes 2 are made diamond-shaped and placed in a checkerboard pattern. Clamp 5 is a leaf spring, one end of which is fastened to the material body 4. Material bodies 4 can be made of any regular and irregular geometric shape (semicircle, circle, 3, 4, 5, 6 coal forms, etc.).

 An example implementation of the method.

 A conduit device was made from a thermoplastic polymer mass, in particular from polyethylene, by extrusion in the form of a perforated body with holes (perforation) from parallel mutually intersecting threads. The thickness of thread 1 is 3.0 mm. At the intersection of threads 1 received holes (perforations) 2 diamond-shaped. The size of the hole, its length along the longitudinal axis of the conduit device, is 35 mm. The size of the hole, its height in the direction perpendicular to the longitudinal axis of the conduit device, is 15 mm. We took a conduit device 2 meters long. In cross section, the conduit device was made in the form of an equilateral triangle with a side equal to 60 mm. We took a telephone cable (wire) 2.5 meters long and inserted one of its ends into the initial part of the perforated body, then applied a load to the cable (wire) and placed the cable (wire) 3 (see Fig. 1 and 2) in the channel conduit pipe. After placing the cable (wire) 3 in the channel of the conduit device, the cable (wire) 3 was fixed relative to the surface of the channel. When placing the cable (wire) 3 in the channel of the conduit device, it was placed so that the cable (wire) 3 passed in the area of the holes 2. Then they took the tool (tool), in particular a screwdriver, and introduced it through the holes (perforations) 2 in the channel conduit pipe and extruded individual parts of the cable (wire) 3 from the zone of holes 2 outside the channel conduit pipe. After that they took material bodies 4 with clamps 5, placed a cable (wire) 3 under clamp 5, then laid material body 4 on the surface of the conduit pipe of the conduit device. Material bodies 4 with clamps 5 can be installed directly in the zone of holes 2 and are somewhat offset from the zone of holes (Fig. 2 shows the location of material bodies 4 with an offset from the zone of holes). This ensures the fixation of the cable (wire) 3 relative to the surface of the conduit tube of the conduit device. This placement of the cable (wire) provides a more dense location in the conduit pipe channel, which facilitates the laying of other cables (wires) in the conduit pipe channel. In addition, this placement of the cable (wire) in the conduit pipe channel provides good access to it during the maintenance and diagnostics of the cable (wire).

 Thus, the proposed technical solution provides a solution to the problem and obtain a new technical result.
