The invention relates to railway transport, in particular for cars, trucks type dumper designed primarily to work in the quarries.

The famous design of the car-truck type dumpcar, protected by a U.S. patent N 4240355, dec. 23, 1980. Oprokidyvaniya wagon.

The disadvantages of analogue should include the fact that the hydraulic system in trains complicate their design.

A device for tilting the body of the car-truck, secure and.with. USSR N 1556978 A1, 61 D 9/02, published in bull. N 14 15.04.90,

The device comprises a pivoted by one end on the lower frame on the longitudinal axis of the power cylinder pivotally connected other ends of the body. On the end walls of the body fixed segment guides the movement of the cylinders with the help of an additional drive.

The use of two air cylinders of large diameter, which is equipped with similar, limits the length of the body, and the complexity of the design of the swivel mechanism does not ensure the reliability of their operation.

The prototype of the invention is a hopper car of the type dumpcar, secure and. C. N 1749090 A1, 61 D 9/10, 60 P 1/28, published in bull. N 27 from 23.07.92, the Invention is used in the development of hoppers (boxcars), described in the branch directory "Cars of the USSR, Moscow, 1989

Heavy wagons in operation, performed axle cargo 145 t (model 34-667 and 34-669). The closest prototype of the cargo it contains a body with an opening sides, to rotate which at 45oin any direction between the trucks fixed six cylinder three on each side. The pneumatic cylinder, with the working cavity 685 mm, double action. The compressed air in the cylinders is supplied by a separate air supply wagon from the compressor locomotive.

The disadvantages of the prototype should include the fact that the large system tipping body at 45oeliminates the possibility to increase the capacity of six-axle car truck type dumper. It also should include the complexity of the manufacture of air cylinders of large diameter, a large number of them on the car and use when dumping body cylinders on one side. In addition, placement of the cylinders tipping body between trucks excludes the possibility to increase the volume of the body and to lower the center of gravity of the load.

The technical result achieved by the invention is that the capacity of dump cars of the type dumpcar on two three-axle bogies may be close to capacity axle car truck type dumpcar payload of 145 tons the weight of the car. In addition, the release receptacle space obesity of the invention is illustrated by drawings, where

in Fig.1 depicts a car-truck type dumpcar in the transport position;

in Fig. 2 - car-truck-type dumpcar, end view, transport position;

in Fig.3 - car-truck-type dumpcar, body lift;

in Fig. 4 - car-truck-type dumpcar, rollover body at an angle of 45o.

Car-truck-type dumpcar 1 (Fig.1) includes a chassis in the form of two three-axle bogies 2, equipped panicaway pillar 3, which are based spinal beam 4, with hinged body 5, is equipped with folding sides 6. On spine beam 4 through the supporting brackets 7 hinged power cylinders 8 of the inclination of the body 5.

Cylinders 8 four, two on each side of the body 5. Through hinged brackets 9 and the end wall 10 of the body 5 and are held in a vertical position. The body 5 of the bottom rests on the pivot beams 11 spinal beams 4. Between the bottom of the body 5 and cap beam 4 set of springs 12 (Fig. 2) installed in the containers 13, rigidly attached to the spine beam 4. To prevent tipping of the body 5 to the spinal beam 4 fixed end brackets 14, which are also used for fastening the cylinder 8, the attachment under the Kotor is 9 places the mounting bracket 7 is also equipped with grooves 16.

Work is carried out as follows. Car-truck-type dumpcar 1 is for loading soil 17 in a state where the body 5 rests on the end brackets 14. For this purpose the cylinders 8 of the body 5 is pressed to the brackets 14 and secured with a locking device latch type. After loading of the soil 17 car-truck-type dumpcar 1 is the locomotive to the place of unloading. Before unloading the body 5 is detached from spine beams 4 and by means of springs 12 and 8 cylinders rises to a height h (Fig.3) defined by the grooves 16. Then, working cylinders 8 in "disorder" is the turning body 5 at an angle of 45o(Fig.4). There is a simultaneous disclosure Board 6 the mechanism is placed in the body 5, which is identical to the prototype.

Unloaded car-truck-type dumpcar 1 returns to its original position, the body 5 is pressed to the brackets 14, snaps and goes for loading.

Accommodation at the ends of the car on two cylinders 8 and under the bottom of the body 5 of the spring 12 provides the ability to create six-axle car truck 1 with a payload up to 145 tons by reducing the diameter and number of cylinders 8 and weight reduction of the body 5.

The invention provides the mm.

1. Car-truck-type dumpcar containing a frame with a thin beam and a support bracket under the hinged body with drop sides and symmetrically arranged along the axis of the carriage on the sides of the spine beams rotating in a vertical plane power cylinders, characterized in that on the spinal beam fixed end brackets to prevent tipping of the body, which is attached to the spine beam through having vertical grooves in their junctions with the supporting brackets, curtain brackets, through which the end walls of the body fixed power cylinders fixed in the spinal beam through the end brackets.

2. Car-truck under item 1, characterized in that on the spinal beam under the bottom of the body is fixed in the container blocks of springs, to facilitate lifting of a loaded body.
