Abstract
Description
ВОСЬМИОСНЫЙ ВАГОН- ДУМПКАР Eight-Axle Dumpcar
Предлагаемое изобретение относится к железнодорожному транспорту и может найти применение при конструировании и изготовлении вагонов-думпкаров большой грузоподъёмности, до 200 т. The present invention relates to railway transport and can find application in the design and manufacture of heavy-duty dumpcars, up to 200 tons
В настоящее время сохраняется потребность в думпкарах большой грузоподъёмности, до 140-200т, для работы на промышленных железнодорожных путях РФ. Эта задача может быть решена при применении для думпкаров четырёхосных тележек. Две четырёхосные тележки при нагрузке на ось, примерно 23,5 т, имеют грузоподъёмность 188 т при собственной массе 20 т. Две трёхосные тележки при такой же нагрузке на ось имеют грузоподъёмность 141 т, а собственную массу - 19,5-20 т, т.е отношение собственных масс к грузоподъёмностям на одну ось (20/188/8 и 20/141/6) равно 1 ,32 к 2,36. Таким образом, применение четырёхосных тележек, состоящих из двух спаренных двухосных серийных тележек, решает две задачи - повышает грузоподъёмность думпкара в 1 ,5-1 ,6 раза, применяя четырехосные тележки, и позволяет экономить дефицитные трёхосные тележки. At present, there remains a need for heavy duty dumpcars, up to 140-200 tons, for work on industrial railway lines of the Russian Federation. This problem can be solved by using four-axle bogies for dump cars. Two four-axle bogies with an axle load of approximately 23.5 tons have a load capacity of 188 tons with an own weight of 20 tons. Two three-axle bogies with the same axle load have a load capacity of 141 tons, and their own weight is 19.5-20 tons, t .e ratio of own masses to load capacities on one axis (20/188/8 and 20/141/6) is equal to 1, 32 to 2,36. Thus, the use of four-axle bogies, consisting of two paired biaxial serial bogies, solves two problems - it increases the loading capacity of the dump car by 1, 5-1, 6 times, using four-axle bogies, and allows you to save scarce three-axle bogies.
Известен восьмиосный вагон-самосвал (см. А.И. Логинов, Н.Е. Афанаскин, «Вагоны-самосвалы», Машиностроение, М., 1975 г., стр115, рис. 73), построенный Калининградским вагоностроительным заводом, в котором два разгрузочных пневмоцилиндра расположены между четырехосными тележками и по одному пневмоцилиндру установлено на концах кузова. The eight-axle dump car is known (see A.I. Loginov, N.E. Afanaskin, “Dump Wagons”, Mechanical Engineering, Moscow, 1975, p. 115, Fig. 73), built by the Kaliningrad Car-Building Plant, in which there are two unloading pneumatic cylinders are located between four-axle bogies and one pneumatic cylinder is installed at the ends of the body.
К недостаткам этого вагона-самосвала можно отнести то, что он плохо вписывается в кривые участки пути из-за большой консольной части между автосцепкой и пятником четырёхосной тележки (4700 мм), кроме того, создается опасно большой опрокидывающий момент при разгрузке вагона. Изобретение решает задачу улучшения вписывания вагона- думпкара в кривые участки пути и уменьшения опрокидывающего момента при разгрузке за счет изменения конструкции двух пневмоцилиндров и места их установки. The disadvantages of this dump truck are that it does not fit well into the curved sections of the track due to the large cantilever part between the automatic coupler and the back of the four-axle truck (4700 mm), in addition, a dangerously large tipping moment is created when the wagon is unloaded. The invention solves the problem of improving the fitting of a dump car into curved sections of the track and reducing the tipping moment during unloading due to a change in the design of two pneumatic cylinders and their installation location.
Для получения необходимого технического результата в восьмиосном вагоне-думпкаре, содержащем кузов, две пары четырехосных тележек, каждая из которых составлена из двух пар двухосных тележек, связанных соединительной балкой, четыре разгрузочных пневмоцилиндра, два из которых установлены между четырехосными тележками, предлагается третий и четвертый пневмоцилиндры установить между двухосными тележками и выполнить с меньшей длиной хода штока по сравнению с длиной хода штока пневмоцилиндров, установленных между четырехосными тележками. To obtain the desired technical result in an eight-axle dump car containing a body, two pairs of four-axle bogies, each of which is composed of two pairs of biaxial bogies connected by a connecting beam, four unloading pneumatic cylinders, two of which are installed between four-axle bogies, the third and fourth pneumatic cylinders are offered install between biaxial bogies and carry out with a shorter stroke length of the rod compared to the stroke length of the pneumatic cylinders installed between the four-axle bogies .

Ц 2 - положение центра тяжести кузова при повороте на 16°, C 2 - the position of the center of gravity of the body when turning 16 °,

В соответствии с расчетами и как подтвердили проведенные испытания, поворот кузова при разгрузке приводит к уменьшению силы, действующей на штоки разгрузочных пневмоцилиндров. Так при повороте кузова в условиях смерзаемости груза на угол 26° центр тяжести кузова Ц о переходит за ребро опрокидывания вагона и занимает положение Ц к In accordance with the calculations and as the tests confirmed, the rotation of the body during unloading leads to a decrease in the force acting on the rods of the unloading pneumatic cylinders. So when turning the body under conditions of freezing of the cargo by an angle of 26 °, the center of gravity of the body Ts o passes over the tipping edge of the car and takes the position Ts to
8 этом случае возникает большой опрокидывающий момент. В условиях ссыпаемости груза центр тяжести кузова Ц о занимает положение Ц 2, угол поворота кузова при этом составляет 16°. Необходимый момент для поворота кузова в этом случае в 3,3 раза (600/182) меньше начального момента, который определяется по формуле М = Q*600 (Q - сила тяжести груженого кузова). In this case, a large overturning moment occurs. Under the conditions of bulk cargo, the center of gravity of the body Ts about occupies the position Ts 2 , the angle of rotation of the body is 16 °. The necessary moment for turning the body in this case is 3.3 times (600/182) less than the initial moment, which is determined by the formula M = Q * 600 (Q is the gravity of a loaded body).
Для уменьшения опрокидывающего момента на думпкарах ставят воздухозамедлители, которые при повороте кузова на 5-10° отключают подачу воздуха в разгрузочные пневмоцилиндры, но этого недостаточно, необходимо выпускать воздух из разгрузочных пневмоцилиндров при угле наклона кузова 20-25°. Эту проблему решает предлагаемое изобретение, при использовании которого момент опрокидывания уменьшается в 2 раза при угле поворота кузова на 20° за счет изменения конструкции двух разгрузочных пневмоцилиндров, а именно, уменьшения длины хода штоков, по сравнению с пневмоцилиндрами, установленными между To reduce the overturning moment, air retarders are placed on the dump cars, which, when the body is turned 5-10 °, turn off the air supply to the unloading pneumatic cylinders, but this is not enough, it is necessary to release air from the unloading pneumatic cylinders at an angle of inclination of the body of 20-25 °. This problem is solved by the present invention, in which the tipping moment is reduced by 2 times at a body rotation angle of 20 ° due to a change in the design of two unloading pneumatic cylinders, namely, reducing the stroke length of the rods, compared with pneumatic cylinders installed between
з четырехосными тележками, вследствие чего они прекращают свою работу раньше. s four-axle carts, as a result of which they stop their work earlier.
При размещении двух разгрузочных пневмоцилиндров над четырехосными тележками между двухосными тележками расстояние от оси подпятника, связывающей тележку соединительной балки до оси автосцепки, такое же, как у вагона-думпкара с трехосными тележками. Практически, по ширине кузова и по осям автосцепки серийный шестиосный думпкар заменен на восьмиосный. Длина предлагаемого вагона- думпкара составляет 15050 мм (длина вагона, описанного в ближайшем аналоге составляет 17503 мм). В предлагаемом техническом решении выбрано оптимальное поперечное сечение кузова, позволяющее получить геометрический объем кузова, равный 60 м3 (такой же объем кузова имеет восьмиосный вагон-думпкар, принятый за ближайший аналог). Шестиосные думпкары имеют объем кузова равный 48-49 м3. When placing two unloading pneumatic cylinders above four-axle bogies between two-axle bogies, the distance from the axis of the thrust linking the connecting beam cart to the automatic coupler axis is the same as that of a dump car with three-axle bogies. In practice, the serial six-axis dump car has been replaced by an eight-axis one along the width of the body and along the axles of the automatic coupler. The length of the proposed dump car is 15050 mm (the length of the car described in the closest analogue is 17503 mm). In the proposed technical solution, the optimal cross-section of the body was selected, which allows to obtain a geometric volume of the body equal to 60 m 3 (the eight-axle dumpcar adopted for the closest analogue has the same body volume). Six-axis dump cars have a body volume of 48-49 m 3 .
Конкретный пример выполнения, предлагаемого восьмиосного вагона- думпкара показан на фиг. 3. A specific exemplary embodiment of the proposed eight-axle dump car is shown in FIG. 3.
Пневмоцилиндры, размещенные между четырехосными тележками, имеют длину хода штока равную 900 мм. Пневмоцилиндры 1 , размещенные между двухосными тележками, выполнены с уменьшенной длиной хода штока равной 400 мм. Пневмоцилиндры 1 закреплены осями на кронштейнах 2 хребтовой балки 3 на таком же расстоянии от оси хребтовой балки, как и пневмоцилиндры, размещенные между четырехосными тележками. Кронштейны 2 на нижней раме закреплены в сечении подпятника соединительной балки тележки. Pneumatic cylinders placed between four-axle bogies have a stroke length of 900 mm. The pneumatic cylinders 1 located between the biaxial bogies are made with a reduced stroke length of the rod equal to 400 mm. The pneumatic cylinders 1 are fixed by axes on the brackets 2 of the spinal beam 3 at the same distance from the axis of the spinal beam as the pneumatic cylinders placed between the four-axle bogies. The brackets 2 on the lower frame are fixed in section of the thrust bearing of the connecting beam of the trolley.
Описание принципа действия пневмоцилиндров предлагаемого восьмиосного вагона- думпкара при осуществлении операции разгрузки. Description of the principle of operation of the pneumatic cylinders of the proposed eight-axle dump car during the unloading operation.
При подаче воздуха во все четыре разгрузочных пневмоцилиндра происходит поворот кузова, при этом ролик 4, закрепленный на штоке 5 разгрузочного пневмоцилиндра 1 давит на плиту 6 цилиндрической формы, закрепленную на кузове 7. При выходе штока на всю длину (400 мм), его давление на кузов прекращается, а дальнейший поворот кузова осуществляется средними пневмоцилиндрами, размещенными между четырехосными тележками, у которых длина хода штока равна 900 мм. When air is supplied to all four unloading pneumatic cylinders, the body rotates, while the roller 4, mounted on the rod 5 of the unloading pneumatic cylinder 1, presses on the plate 6 of a cylindrical shape, mounted on the body 7. When the rod reaches its full length (400 mm), it the pressure on the body ceases, and the further rotation of the body is carried out by the middle pneumatic cylinders located between the four-axle bogies, in which the stroke length of the rod is 900 mm.
После разгрузки при посадке кузова 7 плита 6 давит на ролик 4 штока 5 и возвращает пневмоцилиндр 1 в начальное положение. After unloading when landing the body 7, the plate 6 presses on the roller 4 of the rod 5 and returns the pneumatic cylinder 1 to its initial position.
Таким образом, предлагаемый восьмиосный вагон-думпкар, по сравнению с вагоном, описанным в ближайшем аналоге, имеет меньшую длину, что улучшает его вписывание в кривые участки пути, а также при осуществлении операции разгрузки он обеспечивает снижение опрокидывающего момента, что повышает безопасность операции. Thus, the proposed eight-axle dump car, compared to the car described in the closest analogue, has a shorter length, which improves its fit into the curved sections of the track, and also during the unloading operation it provides a reduction in the tipping moment, which increases the safety of the operation.
