Description

The technical field to which the utility model relates.

The utility model relates to the field of radio electronics, in particular, to the design of mobile workshops for monitoring, diagnostics, maintenance and repair of complex electronic systems (RES).

State of the art

Mobile repair shops are known, which are a semi-trailer van with technological workplaces installed inside the van for carrying out work on monitoring the serviceability of replaceable component parts of equipment, diagnosing malfunctions, repairing identified faulty component parts of equipment, eliminating mechanical structural defects and restoring the original operational characteristics of repaired replaceable components of electronic equipment.

Examples of such installations are the product according to the patent of the Russian Federation for utility model No. 33066 (class B60P 3/14, 2003) and the product according to the patent of the Russian Federation for invention No. 2288113 (class B60P 3/14, 2005).

To repair a wide range of spare parts for RES, a large number of spare parts, electrical components, devices and technological equipment are required, located in cabinets and on shelves above workstations along the walls of the body-container (CC) of the repair shop. With a large severity and a high altitude of placement of technological equipment, spare property and accessories, the center of gravity of the completed repair shop rises relative to the road surface and the center of gravity shifts relative to the longitudinal axis of the repair shop. This increases the likelihood of the mobile repair shop overturning, reduces the effectiveness of its use in the locations of the complex complex distribution stations.

Partially, this drawback was eliminated in the mobile repair shop according to the patent of the Russian Federation for the invention No. 2288113 "Mobile repair and diagnostic complex", adopted as a prototype in relation to the claimed technical solution.

The disadvantages of the prototype is that:

- the equipment of technological workplaces and cabinets in each unified section is divided into three zones in height, the second and third row of which are structurally represented by removable devices, which necessitates the use of special technological furniture not commercially available from the industry. Furniture of this design is made to order, which leads to a rise in price of the manufactured structure and to an unstandardized approach to equipping the product;

- the division of sections into three zones can lead to exceeding the maximum permissible mass of carry-on baggage, which leads to the need to use special equipment and materials;

- preservation of the position of the center of mass on the longitudinal axis of the spacecraft is not provided, which leads to a decrease in the stability of the mobile repair shop during its transportation to the place of work.

Utility Model Disclosure

The technical result from the use of the proposed utility model is:

- increasing the stability of a mobile repair shop in harsh conditions of transportation, regardless of its configuration;

- the possibility of using standard technological equipment manufactured in series by industry;

- the ability to transfer the spacecraft from the worker to the transport position (and vice versa) without the use of additional devices;

- improvement of the operational and technical characteristics (patency) of the repair and diagnostic complex during maintenance and repair of complex distribution networks in hard-to-reach places of their deployment.

This technical result is achieved by the fact that technological workplaces, equipment and cabinets for storing spare property, accessories, tools and documents are installed in the spacecraft of the mobile repair shop along the perimeter, made in the form of products widely released by the industry, on which the technological equipment is placed in the working position , sets of spare parts, tools, accessories and materials, documents. Masses of piling do not exceed the maximum allowable standards established for hand luggage. In accordance with the real values of the partial masses and the real position of the coordinates of the centers of mass of the units of equipment and packaging of property, the most optimal variant of the re-arrangement of the equipment of repair shops when moving from a worker to a transport position is calculated. Based on the selected rearrangement option, the design of the spacecraft includes the necessary sets of embedded fastening elements for fixing the laying of technological equipment. In the operational documentation of each repair shop, a method for transferring the repair shop to the transport position is described. In accordance with the operational documentation, when the repair shop is in the transport position, the laying of technological equipment is moved and rigidly fixed in the technological passage with the exception of the possibility of displacement with a strong roll or tipping of the spacecraft.

If the mobile repair shop includes an automated system for controlling technological processes and resources, it is possible to transfer the workshop from a worker to a transport position (and vice versa) under its control. To do this, in the memory of the automated process control system and resources it is necessary to enter all the necessary information on the procedure for transferring the repair shop from the worker to the transport position (and vice versa) in the form of step-by-step instructions for action.

Utility Model Implementation

The principle of technical implementation of the claimed device is illustrated by the example of a mobile repair shop, schematically represented in figure 1.

Figure 1 illustrates the design of a typical QC, the width of which is 2a, the height of the chassis h, and the height of the body c, where the height of the chassis is two times less than the height of the QC case. To analyze the stability of a typical QC, we introduce a coordinate system, as shown in Fig. 1.

The stability of the spacecraft is characterized by an acceptable angle of inclination of the spacecraft before tipping over (the larger the allowable angle of inclination of the spacecraft before tipping, the higher the stability of the spacecraft). Tipping angle - the largest angle of deviation of the spacecraft from the vertical, at which tipping begins when the spacecraft is tilted both to the right and to the left.

The tipping angle of a typical mobile repair shop is determined from the design geometry of the spacecraft and the position of the partial centers of mass of the components of the spacecraft.

The initial position of the QC is shown in figure 2. When the spacecraft is tilted to one of the sides, the emphasis will be on the point X ', as shown in Fig.3.

The tipping angle α will be determined by the position of the center of mass (point C) on a straight line perpendicular to the x axis and intersecting it at point X '.

According to FIG. 3, the tipping angle α is the angle ∠CX′F. ∠CX'F = ∠OCX ', because (OC) || (X'F). Then

where x is the coordinate value of the center of mass of the spacecraft along the x axis;

z is the coordinate value of the center of mass of the spacecraft along the z axis.

Determine the coordinates of the center of mass of an empty spacecraft based on the relationships presented in the book "Geometry of Masses" (M.B. Baln, V. G. Boltyansky. Geometry of Mass. - M .: Nauka, 1987.-160 p.

where m is the total mass of the system in question;

m _i is the mass of the i-th element of the system under consideration;

n is the number of elements.

We accept the assumption that the walls of the spacecraft and the upper part of the chassis are approximated by equivalent parallelepipeds, the centers of mass are located in geometric centers. The masses of CC walls are assumed to be the same and equal to m _c [kg]. The mass of the chassis is taken equal to 1.5 m _s . The position of the center of mass of the empty spacecraft corresponds to point C _P. Given the symmetry of the design of the empty spacecraft, we obtain the relations for the coordinates of the initial position of the center of mass (point C _P ):

The value of the coordinate y _{P is} unprincipled, because it does not affect lateral rollovers.

We determine how the coordinates of the center of mass of the loaded spacecraft change. Technological equipment and property included in the set of the repair shop is located on both sides of the aisle in the technological compartment - as shown in Fig.4. Typically, equipment and property are unevenly distributed over their masses. Above workplaces (tables, workbenches) there may be empty seats. We take the partial mass of a unit of equipment (stacking property) equal to m.

We consider how the position of the resulting center of mass of the equipped repair shop will change for the partial mass placement option shown in Fig. 4. Accept:

Based on relations (2) and (4), taking into account the distribution of partial masses shown in Fig. 4, we obtain the coordinates x _p and z _{p of the} resulting position of the center of mass C _{p of the} loaded CC:

Based on relations (1) and (5), we obtain the value of the tipping angle α _{p of the} loaded CC:

For clarity, we assume that the height of the chassis is equal to half the width of the spacecraft.

Therefore, in the example under consideration, when tilting more than 23 °, when the spacecraft equipped according to Fig. 4 moves, capsize.

We consider how the value of the tipping angle will change if, when the mobile repair shop is in transport position, the removable equipment and property will be located on the spacecraft floor and placed symmetrically - as shown in Fig. 5. The property in this case is placed in two levels symmetrically about the y axis. In this case, heavier styling is located at the lower level.

The coordinates of the resulting position of the center of mass With _T for the repair shop, translated into transport position according to figure 5, are determined by the relations:

The value of the tipping angle α _T in this case will be:

Thus, the rearrangement of the technological equipment of the repair shop when moving from the operating position according to FIG. 4 to the transport position according to FIG. 5 allows to increase the tipping angle by almost 1.5 times, which means a significant increase in the stability of the mobile repair shop during transportation. A similar effect will be achieved with other combinations of masses of equipment located in the spacecraft.

An example of QC is KK6.2.30.1.030, manufactured by ShZSA, Shumerlya. Examples of technological equipment that can be installed in the spacecraft include: cabinets (for example: 08.3106-7016 / G, manufactured by the Ferrum plant; ШД-3, manufactured by the Dipol NPF), workbenches (for example: 08.014, manufactured by the Ferrum plant) , tables (for example: СУ1-12-5, Dipol NPF is produced), as well as other technological equipment manufactured by the industry.

The implementation of the claimed device provides the claimed technical effect, namely:

- increasing the stability of mobile repair shops in harsh conditions of transportation, regardless of its configuration;

- the possibility of using standard technological equipment manufactured in series by industry;

- the possibility of transferring the spacecraft from the worker to the transport position and, conversely, without the use of additional devices;

- improvement of the operational and technical characteristics (patency) of the repair and diagnostic complex during maintenance and repair of complex distribution networks in hard-to-reach places of their deployment.
