Description

FIELD OF TECHNOLOGY

The invention relates to linking devices (UU) of open universal railway gondola cars during bulk transportation of solid bulk cargoes.

BACKGROUND

When transporting cargo in a vehicle, it is necessary to ensure the safety of the cargo and the vehicle, as well as the safety of the vehicle. To do this, after loading, the cargo is leveled and secured, and its surface is protected by a shelter from external influences.

Means of securing cargo. For securing goods in wagons, the following securing means are used - extensions, strapping, ties, ties, wooden racks, bars and shields, thrust shoes, lodges and other devices. Fasteners can be disposable and reusable. When mounting fasteners on a wagon, standard fasteners are used: bolts, studs, nails, building brackets, cables and other products (Technical conditions for the placement and fastening of goods in wagons and containers. - M.: Law Firm Yurtrans, 2003. - 544 from.).

Fastening and sheltering of cargoes with the help of binding devices and means of fastening. For fastening and sheltering cargoes in standard open wagons, binding devices are used that are mounted on the walls of the car, as well as fastening means - extensions, strapping, ties and ties. The extension is fixed at one end to the SU on the car body, and the other end of the extension is attached to the SU on the load. The harness covers the load and is fixed at both ends for the tie-down devices on the car body. The screed is designed to connect with each other and tension the fastening means, as a rule, stretch marks, harnesses, racks. Linking is designed to combine individual units of cargo into one package.

For the manufacture of stretch marks, strapping, ties, ties, use steel wire in a heat-treated (annealing) state of circular or square section, steel strips, steel chains, cables, ropes. The use of other materials for the manufacture of stretch marks, bindings, screeds, ties, is subject to confirmation of their reliability and by agreement between the railways involved in transportation.

The diameter of the round section must be at least 5 mm; the cross-sectional area of non-circular steel should be at least 20 mm. On the surface of the rental should not be mechanical damage, cracks, twists, delaminations and scoring.

Gondola devices for gondola cars. To fix the fastening means (extensions, strapping, ties, ties) in gondola cars, various linking devices are used, which are located on the inner and outer walls of the gondola car. The internal linking devices of a gondola car include lower UU, middle UU, upper UU, forest brace, lower harness, and the upper external UU belong to upper linking devices. Gondola wiring devices are mounted, as a rule, in the area of the racks of the side walls. Note that the distance between the racks is about 1.8 m.

The lower linking devices of the gondola are made in the form of metal scarves, the middle linking devices in the form of metal loops located on the racks of the side walls at a height of 1100-1200 mm from the floor, the upper linking devices in the form of brackets inside and outside the upper body harness (Technical conditions for placement and fastening cargo in wagons and containers. - M.: Law Firm "Yurgrans", 2003. - 544 p.). It should be noted that the sender is responsible for the quality and reliability of the fasteners. When using multi-turn fasteners, the departure railway has the right to demand from the sender the certificate of periodic inspection of the multi-turn fasteners, confirming its suitability for use.

Typical linking devices of a universal gondola car (UPV) are shown in FIG. one.

Requirements for linking devices for permissible loads. For all types of coupling devices for open wagons there are requirements for permissible loads ("Agreement on International Railway Freight Traffic (SMGS)" Text of the document as amended and updated as of September 2013, http://www.levonevski.net/pravo/norm2013 /num73/d73019/page92.html).

Permissible loads on the coupling devices of gondola cars are given in Table 1.

We consider in more detail the average linking devices of gondola cars. Middle UU made in the form of metal loops located on the racks of the side walls at a height of 1100-1200 mm from the floor. The number of SU on the side wall of a four-axle railway gondola corresponds to the number of racks. On the side wall of a four-axle gondola car, as a rule, there are 8 SUs. At the same time, the distance between the average UE is about 1.8 m. The permissible load on the average UE of gondola cars built after 1974 is 3.0 tons of force.

The disadvantages of standard medium-sized UU. Standard medium-sized UUs located at a height of 1100-1200 mm from the floor cannot be used for fastening and linking the shelter of lump and granular sulfur. This is due to the fact that with fluctuations in the bulk density of the sulfur cargo, for example, from 1.1 to 1.4 t / m ³ (lump sulfur density 1.4 t / m ³ , granular sulfur density 1.1-1.3 t / m ³ ) the level of sulfur adjacent to the wall of the wagon (taking into account the presence of a central ridge with a height of 0.2 m) varies from 1.25 to 1.8 m. In addition, the distance between neighboring standard control units is about 1.8 m, which is a lot, and will not provide high-quality fastening and coordination of the shelter. In this regard, shippers of lump and granular sulfur are forced to organize the installation of additional medium-sized CUs in the used fleet of cars for transporting sulfur.

Additional medium-sized control units made in the form of brackets are often damaged and even come off the walls of the cars during loading and unloading operations, which necessitates the repair of these control units during long-term operation. In addition, the presence of UU metal parts in a sulfur cargo is not allowed.

For example, the weight of a container used for loading sulfur reaches 30 tons. And when lowering the container inside the car, to avoid sulfur dusting, the UU brackets are damaged. UU brackets are also damaged when unloading sulfur from wagons using grabs. To increase the productivity of unloading with grabs due to a more complete filling of the bucket, the grab is thrown onto the load. Often this happens when the turn of the boom of the crane is not yet completed and therefore often accompanied by impacts of the opened grab on the upper strapping of the gondola or on the casing. When unloading the lower part of the cargo in the body when closing the jaws of the grab, damage occurs not only to the control unit, but also to the horizontal shelves of the transverse beams ((“Damage and repair of gondola bodies” - http://www.vagonnik.net.ru/index.php?name = Pages & op = page & pid = 98), http://scbist.com/novosti-na-seti-dorog/4621-na-protyazhenii-yanvarya-gruzopoluchateli-povredili-bolee-10-tys-vaKonov.html).

The appearance of damage to the side wall of a four-axle gondola car of model 12-532 is shown in FIG. 2. In FIG. 2 on the side wall of the gondola car, dents are visible from impacts on the inner wall of the gondola car having a wall thickness of 5 mm (4-axle gondola car, model 12-532, http://scaletrainsclub.com/board/viewtopic.php?f=46&t=3662 )

It is also proposed to use through holes drilled in the sides of the gondola as a middle linking device, through which the strapping tapes loop out to the outside of the car for attaching a shelter to the sides (walls) of the body: a shelter for transporting bulk chemical goods in a vehicle body, containing a rectangular panel made of rectangular flexible laminated polypropylene material, around the perimeter of which round brackets are fixed, through which a flexible element in the form of polypropylene is passed th tape for attaching the panel to the sides of the vehicle body above the level of the cargo by hooking a flexible element in the form of pieces of strapping polypropylene tape, which is looped to the outer surface of the gondola car through through holes previously drilled in the sides of the gondola car for tight tension of the panel to the inner sides of the gondola car body (RF patent for utility model No. 74879).

The disadvantages of this linking device in the form of through holes in the walls (sides) of the gondola car are as follows. Wagon depressurization takes place, and dangerous goods, such as granular sulfur, or sulfur dust, can spill out of a gondola car while driving; this will especially be observed in the presence of several rows of holes in height. This contradicts the agreement on special conditions for the transport of dangerous sulfur cargo concluded between the railway and the cargo owner (http://docs.cntd.ru/document/901974956 “Special conditions are established for all shippers on the transportation of lump sulfur and granulated sulfur from stations of the Russian Railways until cancellation ").

The indicated drawbacks are deprived of linking devices made in the form of combs installed along the perimeter of cars in a vertical position (RF patent for utility model No. 133475). Shelves of combs along the entire length of the combs are welded to the car wall in an upright position. The distance between adjacent combs is set so as to provide the necessary frequency of fastening and linking of the shelter. Each shelf of the corner has many through holes (for example, 7 pieces), evenly spaced along the length of the corner, which are used as UU. The through holes of one shelf are flush with the through holes of another shelf.

The specified comb linking device is made in anti-vandal performance of low-alloy steel of high strength. It is resistant to impacts of the grab from the left and right sides, as well as to impacts from above and below due to the use of equal hollow perforated corners having bevels of planes with respect to the direction of impact from the left and right sides, as well as having bevels in the lower and upper part of the comb .

The disadvantages of UU in the form of a comb according to the patent of the Russian Federation for utility model No. 133475 are as follows. As practice has shown, the combs of the tie-down device are well attached to the walls of open wagons with flat, flat walls. Combs of the linking device can also be mounted on the side walls of gondola cars with long trough-shaped corrugations (Fig. 3), the longitudinal axis of which is vertical.

In this case, the vertical combs can be placed inside the sinus of the vertical trough-like trough, and they will be less susceptible to mechanical stress during loading and unloading (Fig. 4).

In addition to gondola cars with even side walls and side walls with vertical trough-like gutters, gondola cars having side walls with horizontal trough-like gutters curved outward to increase the car volume are widespread (Fig. 5, Fig. 6). The gutters give additional rigidity and bending strength to the walls of the cars, which experience heavy loads from the load, and especially when loading and unloading.

When fastening vertical combs on the side walls of gondola cars with horizontal gutters, an air gap is formed between the comb and the gutter to the depth of the gutter. During loading and unloading operations of granular and lump sulfur in open wagons, the comb can be broken in the area of the gap by the protruding parts of the loading and unloading devices, for example, the comb is broken by the teeth of the grab bucket during sulfur unloading.

Many modern car models have all-metal side walls with a thickness of 4-5 mm, in which the metal casing is also not smooth, has no horizontal grooves, but at the same time is made of sheets of a bent profile with longitudinally arranged corrugations (V. Lukin, Yu. Fedoseev. , Anisimov P. Wagons. General course. Textbook for universities. Publisher: Route, 2004. ISBN: 5-89035-106-0). Longitudinally located trough-shaped corrugations with a depth of up to 40 mm give the necessary rigidity to the walls of the cars (http://jelesnodorojnik.ru/index.php/2012-10-09-03-46-57/68-9-/259-92-). In this case, the use of a linking device in the form of a long comb is also undesirable due to the fact that the part of the comb (vertical attachment of the comb), which is located in the area of the trough-shaped corrugation, will not be fixed to the walls of the carriage, and during loading and unloading operations, the comb may be torn from the walls of the carriage by the protruding parts of the loading and unloading mechanism.

DETAILED DESCRIPTION OF THE INVENTION

A hardening impact-resistant linking device (UUUU) for fastening shelters to a vertical wall of a vehicle body is made in the form of an elongated metal profile containing at least two shelves having such an external surface that is achievable for impacts during loading and unloading after installation on the said wall wherein said surface has a zone located along said profile and made in such a shape that the plane tangent to it will have a positive inclination ( vertically from top to bottom) 35 ÷ 45 ° to the plane of said wall when installing said profile on said wall, and an area located along said profile made in such a way that the plane tangent to it will have a negative inclination (in the direction from top to bottom) 35 ÷ 45 ° to the plane of said wall when installing said profile on said wall, and a frontal zone located between said zones, while the edges of said shelves are essentially in the same plane Thus, in order to allow them to be welded to the said wall, in addition, the said shelves have through holes for rigging elements, some of which (holes) are on one side of the said frontal zone and are staggered relative to the other part of these holes, which is located on the other side of the said frontal zone.

In one particular embodiment of the invention, which is given and described in detail below for purposes of illustration, the profile is a perforated equal-angle corner 10 of low-alloy steel type 09G2S having holes with a diameter of D on both flanges of the corner (Fig. 7).

Parameters of UUUU. The angle α between the shelves of the corner can vary from 90 ° to 110 °, which is determined on the one hand (90 °) by impact resistance, and on the other hand (110 °) by the convenience of work when fastening and linking the shelter or cargo with a cable or tape.

To strengthen the design of an equal-shelf perforated corner, the holes on one shelf of the corner are made asymmetric with respect to the holes on the other shelf of the same corner. This is achieved by shifting the center of neighboring holes (on different shelves of the corner) by S. The value of S can range from D to 2D. When S is less than D, the structural strength of the UUUU decreases, when S is more than 2D, difficulties arise in threading cables or tapes through holes.

The distance l between the holes is selected so as to provide the necessary frequency of fastening and linking of the shelter. This is important for sheltering a load of flammable sulfur so that there are no exposed areas of sulfur.

The holes 11 have a radius of rounding R, so that during the movement of the fastening tape or tape ties did not rub against the sharp edges of the holes.

Fastening UUUU to the wall of the car. The fastening of an equal-shelf perforated corner with asymmetric holes to the walls of the car is shown in FIG. 8. Pieces of equal-perforated perforated corner of a certain length (say 2 ÷ 4 m) are mounted on the walls of the car end-to-end. For initial fastening, bolts with washers and nuts are used. To do this, holes are drilled in the corners and wall of the car, the diameter of which is slightly larger than the diameter of the bolt. After fixing pieces of the corner to the car wall with bolts, washers and nuts, the fastening is strengthened by welding the metal of the corner and the car wall (pos. 13). The frequency and length of the welds should provide the allowable load on the middle linking devices of open wagons. As previously mentioned, the permissible loads (http://www.levonevski.net/pravo/norm2013/num73/d73019/page92.html) on the average linking devices of gondola cars are 2.5-3.0 tf (tons of force). One row of equal-shelf perforated corner, welded in many places to the wall of the car along the perimeter, increases the rigidity of the walls of the car and increases the strength of the walls of the cars by breaking along the perimeter of the car.

Therefore, a number of equal-shelf perforated corner, which is welded continuously without gaps in many places to the car wall along the perimeter, can be defined as a hardening impact-resistant linking device (UUUU). Three rows of equal-shelf perforated corners, which are continuously welded without gaps in many places to the car wall along the perimeter, further strengthen the rigidity and strength of the side and end walls of the car (see Fig. 8).

Gondola with three rows of reinforcing shock-resistant linking devices (UUUU) is shown in Fig.9.

UUUU are mounted around the perimeter of the car at three different heights h from the floor of the gondola. The lower row of UUUU is located at a height of h ₁ from the floor of the gondola car. The middle row of the UUUU is located at a height of h ₂ from the floor of the gondola. The upper row of the UUUU is located at a height of h ₃ from the floor of the gondola car.

In relation to sulfur, the various batches of which have a bulk density in the range of 1.1 ÷ 1.4 t / m ³ , the lower row of UUUU is designed for fixing sulfur shelters granular with a bulk density of 1.1 ÷ 1.25 t / m ³ , the middle row UUUU is designed for fastening sulfur shelters granular with a bulk density of 1.2 ÷ 1.35 t / m ³ , the upper row of UUUU is designed for fastening sulfur shelters with lump with a bulk density of 1.3 ÷ 1.4 t / m ³ .

This allows us to solve the problem of shelter sailing - to ensure minimum shelter sail (the distance between the surface of the sulfur load and the plane of fastening of the shelter). A large number of holes in the UUUU provides a snug fit between the edges of the shelter and the wall of the car (it is necessary that the number of eyelets in the shelter corresponds to the number of holes in the UUUU).

Pieces of an equal-shelf perforated corner of a certain length (say 2-4 m) are mounted on the walls of the car end-to-end and without gaps, and form a single relatively smooth horizontal surface of the UUUU along the perimeter of the car.

Therefore, side impacts of the UUUU are not terrible. The use of three rows of UUUU allows you to protect two rows of UUUU from blows from above and below - one upper row of UUUU (strike from above) or the lower row of UUUU (strike from below) take a hit (see Fig. 9).

Thus, for securing loads and for securing shelters of lump and granular sulfur, it is proposed to use an equal-flange perforated corner made of low-alloy steel type 09G2S with holes with a diameter of D on both flanges of the corner, while the angle α between the flanges of the corner is in the range from 90 ° to 110 ° , and the shift of the center of neighboring holes (on different shelves of the corner) is equal to the value of S in the range from D to 2D. The distance l between the holes is chosen so as to provide the necessary frequency of fastening and linking the shelter, while the distance between the grommets of the sulfur shelter should also be approximately equal to the value of l.

Strengthening shock-resistant UU can be placed on the perimeter of the walls of the following cars:

- cars with smooth walls;

- wagons whose walls have horizontal gutters (option 1: linking devices are mounted between the gutters; option 2: linking devices are attached along the horizontal median line of the gutter, while the linking device repeats the relief of the wall of the carriage - for this, the linking device is cut into pieces of the required length, and the joints binding devices do not have gaps of more than a few mm);

- wagons whose walls have longitudinally (horizontally) located trough-shaped corrugations.

The design of the UUUU allows you to place them in rows at different heights from the floor level, which allows you to solve the problem of shelter sail, and the necessary (sufficiently large) number of holes in the UUUU provides a snug fit between the edges of the shelter and the wall of the car.

The use of equal-shelf perforated corners with asymmetric holes in opposite shelves, which are fastened around the perimeter of the gondola walls with bolts and welding, can increase the impact resistance of UU during loading and unloading operations, as well as to strengthen the structure of car walls by increasing the rigidity of car walls and increasing strength walls of cars to break along the perimeter of the car.
