These laboratories are equipped with devices for the forced supply of conditioned (and, if necessary, heated) air, good lighting. The installer’s workplace is equipped with an installation table and an adjustable seat. P1 there are special cabinets for storing tools, fixtures, equipment and materials. The ends of the spliced cables are fed into the laboratories through the rear entrance doors equipped with special power supply units (Technical proposals for the development of a module for mounting and measuring fiber-optic cables, M, NIIAS ZhT MPS of Russia, 1999, p. 3, Fig. 1).

The closest in technical essence and the achieved effect to the claimed utility model is a special mobile measuring laboratory (LIOK), which is a special ZIL-131 car, on the chassis of which a closed-type body (KUNG) is installed, selected for the prototype (Construction and maintenance of fiber-optic communication lines. A textbook for universities (V.A. Andreev, V.A. Burdin, B.V. Popov, A.I. Polonikov; edited by B.V. Popov - Moscow: Radio and Communication, 1995, p. .148, 149). The closed-type body forms an external body, equipped with equipped with equipment for measuring and installation work.

a device for fixing the ends of the cable to be mounted and the placement of installation tools. It also provides a place for transporting a device for welding optical fibers of a cable and working with it during installation. Workers of the installers are equipped with swivel chairs with height adjustment. In the front of the body there is a cabinet for storing and transporting measuring instruments and a workbench to perform related work. To the right in the direction of travel are the lari seats, designed for large tools of equipment and materials. Lighting in the cabin is natural (through windows) and artificial (from lamps in shades with a voltage of 12 V) located near the assembly table and workbench. All electric consumers are powered from the on-board 12 V network or the AB-1 benzoelectric unit through the power supply rack. To connect the unit to the power board there is a set of cables on rotating coils. For official communication between laboratories during installation and measurement, a radio station is used, the telescopic antenna mast of which is fixed outside the body. Interior heating in the cold season is carried out by a gasoline heater located in front of the body.

To complete the installation of the OK coupler, a LIOC is installed, as close as possible to the pit (when installing the cable in the field) or to the viewing device (when installing the cable laid in the telephone conduit). The ends of the OK are fed into the mounting and measuring machine, secured to the mounting machine, separated and mounted in accordance with the technological maps of the labor processes developed for specific OK designs.

In our country, this laboratory is most widely used for installation work.

However, the specific conditions for the passage of railway lines in the Russian Federation (along swampy, mountainous and forested areas) in the absence of dirt roads along the path, the design features of the subgrade (embankment, excavation, half-embankment, half-excavation) often do not allow installation and measurement laboratories for auto and tracked and encouraged to use tents when performing installation and measurement of cables.

It is difficult to ensure the high quality of installation and measuring works when using tents. Due to the fact that the tent is located in the immediate vicinity of the track, the execution of work is complicated by the powerful air flow from passing trains carrying dust, debris, snow, etc.

An analysis of the technical characteristics of the LIOK type laboratories shows that their use in the construction and operation of FOCL MPS is significantly difficult, and in many cases impossible. This is due to the following reasons:

The laboratory should be located in close proximity to the ends of the cables being mounted, which, when working with cables suspended on the supports of the contact network or laid in the subgrade of the railway, as a rule, is not possible (the presence of embankments, recesses, pressure sections, lack of access, etc. );

When laying cables outside the subgrade on rough terrain, it is not possible to install the installation and measurement laboratory on a motor vehicle in a horizontal position in most cases.

When installing cables laid in the subgrade of the railway, the mobile station should be installed on the embankment (in the recess), which cannot be provided when placing the LIOK on the chassis of the ZIL-131.

The use of only a KUNG body as a mobile point, periodically removed from the chassis of the car and delivered to the installation site by vehicles on a railway track, is impractical, because a body made of sheet iron and plywood is not intended for frequent removal and installation on the vehicle chassis and a large number of loading, unloading and installation cycles during installation and measurement of the wok. The installation of such a body on a subgrade with an overhang, a half-embankment - a half-notch, is not possible due to the narrowness of the curb.

Thus, in order to perform construction, maintenance and emergency recovery of FOCL MPS, it is necessary to create a special mobile station (module) for the installation and measurement of FOCs, which meets all the requirements arising from the specifics of FOCs installation compared to traditional methods, construction of the railway subgrade and the specifics of the construction and operation of railway lines.

The task to which the claimed utility model is directed is to improve the quality of installation and measurement of FOCs, increase labor productivity, improve the conditions for mounting and measuring FOCs when performing emergency recovery work.

The technical result that can be obtained using the utility model consists in the possibility of installing the module on railway embankments, in excavations and at zero elevations, as well as outside the subgrade of the railway on rough terrain, as well as in the possibility of implementing a module with high technical economic indicators and functional planning opportunities.

The problem is solved due to the fact that in the module for installation and measurement of FOCs installed and transported on a vehicle containing an external casing, equipped with equipment for installation and laboratory work. The design of this building is made in the form of a mobile inventory building - a container, based on a welded building. The module is also equipped with an installation device that allows you to install the module on the subgrade of the railway and on rough terrain, which consists of four tubular supports, of which two are short, mounted on the side of the track or on top of the slope, and two are long telescopic mounted on the side of the field or down the hill. In this case, the supports are placed in guide brackets attached to the plates welded to the supporting structures of the module.

In addition, the front door and the door for loading and unloading the benzo-electric unit are provided in the body structure. In the longitudinal wall there should be two light and working openings.

Thus, an increase in the quality of installation and wok measurements is achieved through the use of new structural elements, blocks and a device for installing the module in the module.

The essence of the utility model is illustrated by drawings, where in FIG. 1 shows a general view of a module for mounting and measuring a wok located on an embankment; figure 2 is a view of this module located in the cuvette; on figs. 3 is a view of this module located on the slope.

The wok assembly and measurement module consists of the following elements, nodes:

case 1, recruited from a unified three-beam nodes, as well as the installation device, including:

tubular supports 2, of which short 2.1 and long telescopic 2.2;

guide brackets 3

plates 4

screws 5.

The design of the housing 1 of the wok assembly and measurement module is based on the principle of a spatial (along the edges of a parallelepiped), power frame made of a bent profile, connected by inserts of various lengths.

A closed volume is formed after filling the power frame with enclosing structures - profiled steel sheet, communicated from the inside by plastic sandwich panels.

In the housing 1 of the module should be provided located at the end of the front door and the door for loading and unloading of the gas-electric unit. In the longitudinal wall facing the paths, there should be two openings: one is a window, the other is a worker, intended for input-cables and the input of a mounted sleeve with cables. The upper and lower belts of the frame must have corner fittings with holes according to the type of cargo containers.

Installation devices are designed to enable installation of the module within the approximation of the railway track structures on embankments, in ditches and at zero elevations, as well as outside the railway subgrade on rough terrain.

The installation device includes four tube supports 2: two short 2.1 mounted on the side of the track, and two long telescopic 2.2 mounted on the side of the field. Supports 2 are placed in the guide brackets 3, fastened with bolts to the plates 4, welded to the supporting structures of the housing 1

module. The horizontal installation of the module is ensured by adjusting the length of the supports 2. The coarse adjustment is made by moving the supports and installing fingers in the holes located on the side surface of the supports 2. Precise adjustment of the length of the output of the supports 2 is provided using screws 5 screwed from the tubular supports 2.

To ensure the stability of the supports 2 and to prevent the sliding of their support heels when installing the module on the hinges, each of the heels is equipped with pointed pins. For the convenience of service personnel, the module is equipped with a platform with a fence that is attached to its load-bearing structures from the front door and the hatch of the power unit compartment.

The platform is installed on five loops, with the help of which it is quickly transferred from the transport position to the working one and vice versa. At the same site, removable racks are mounted on which enclosing chains are fastened with a quick-detachable mount.

All designs of installation devices are removable and are used only if necessary; if unnecessary, they can be removed.

In the transport position, the supports 2 rise up in the brackets 3 and are fixed with the fingers; the platform with the fence rises and is fixed with a special device.

The internal layout of the module, the equipment of the workplace of the installers in it, and the placement of the equipment must comply with the basic ergonomic requirements that take into account the nature and duration of the work and special requirements for the workplace of the wok fitter. For fiber-optic cable cores, the dimensions of workplaces should be established taking into account the following indicators:

the ends of the wok during installation are divided into a length of about 1500 mm;

coupling length is (assembled) 760-800 mm; during installation, parts of it can be pushed onto the ends of the cables;

allowable bending radius must be at least 20 cable diameters; therefore, it will be 400-480 mm (depending on the design of the cables and the number of fibers).

For the production of installation and measuring work, the placement of equipment and

equipment area of the module should be at least 5 m.

The choice of equipment placement option, taking into account the general requirements for the installation of FOCs, the determination of the dimensions and approximate mass of the main technological equipment, ways of securing it during transportation, the solution of lighting, heating and ventilation issues, are determined in each case.
