Description

Изобретение относится к горной промышленности, в частности к устройствам ударного действия для разрушения горных пород.The invention relates to the mining industry, in particular to shock devices for rock destruction.

Целью изобретения является повышение эксплуатационной надежности и упрощение технологии изготовления устройства.The aim of the invention is to increase operational reliability and simplify the manufacturing technology of the device.

На фиг. 1 изображен общий вид устройства (частичный продольный разрез в рабочем положении); на фиг. 2 - поперечное сечение средней части (разрез по А-А фиг. 1)’.In FIG. 1 shows a General view of the device (partial longitudinal section in the working position); in FIG. 2 is a cross section of the middle part (section along AA of FIG. 1) ’.

Устройство содержит корпус 1 с инструментом 2, на который воздействует ударник 3, разделяющий полость корпуса I на камеру 4 прямого хода и камеру 5 обратного хода.The device comprises a housing 1 with a tool 2, which is impacted by a hammer 3, dividing the cavity of the housing I on the forward-motion chamber 4 and the reverse-motion chamber 5.

Механизм 6 воздухораспределения связан с камерой 4 с помощью каналов 7, которые выходят в полость корпуса 1 на уровне кольцевой .проточки 8 ударника 3 в его крайнем переднем положении (т.е., когда он взаимодействует с инструментом 2).The air distribution mechanism 6 is connected to the chamber 4 by means of channels 7, which extend into the cavity of the housing 1 at the level of the annular groove 8 of the hammer 3 in its extreme forward position (i.e., when it interacts with the tool 2).

На наружной поверхности ударника 3 выполнены лыски 9, которые совместно с внутренней поверхностью корпуса 1 образуют каналы 10, открытые в кольцевую проточку 8 ударника 3 для подвода энергоносителя в камеру 5.On the outer surface of the striker 3 flats 9 are made, which together with the inner surface of the housing 1 form channels 10 that are open in the annular groove 8 of the striker 3 for supplying energy to the chamber 5.

На верхнем конце ударника 3 выполнен· уплотняющий пояс 11. Для подсоединения к магистрали сжатого воздуха устройство снабжено патрубком 12, а для выхлопа предусмотрены окна 13.At the upper end of the hammer 3, a sealing belt 11 is made. For connecting to the compressed air line, the device is equipped with a pipe 12, and windows 13 are provided for exhaust.

Устройство работает следующим образом.The device operates as follows.

В момент запуска ударник 3 контактирует с инструментом 2, а проточка 8 совпадает с выходом‘каналов 7. При этом сжатый воздух через патрубок 12, механизм 6 воздухораспределения, каналы 7, проточку 8 и ка5 налы 10 поступает в камеру 5. Ударник 3 совершает движение вверх, пока нижняя кромка пояса 11 не откроет окна 13.At the time of launch, the hammer 3 is in contact with the tool 2, and the groove 8 coincides with the output of the channels 7. In this case, compressed air through the pipe 12, the air distribution mechanism 6, channels 7, the groove 8 and channels 10 enters the chamber 5. The hammer 3 makes a movement up until the lower edge of the belt 11 will not open the window 13.

При подъеме ударника 3 происхо10 дит сжатие воздуха в камере 4, в результате чего механизм 6 Ъоздухораспределения переключает подачу сжатого воздуха на камеру 4. Ударник 3 совершает движение вниз и воз15 действует на инструмент 2.When the hammer 3 is lifted, air is compressed in the chamber 4, as a result of which the air distribution mechanism 6 switches the compressed air supply to the chamber 4. The hammer 3 moves downward and acts on the tool 2.

С этого момента цикл работы повторяется.From this moment, the cycle of work repeats.

Claims

The invention relates to the mining industry, in particular, to percussion devices for the destruction of rocks. The chain of the invention is to improve the operational reliability and simplify the manufacturing technology of the device. FIG. 1 shows a general view of the device (partial longitudinal section in the working position); in fig. 2 is a cross section of the middle part (section along A-A of FIG. 1). The device comprises a housing 1 with a tool 2, on which the hammer 3 acts, dividing the polo of the housing 1 into the forward stroke chamber A and the reverse stroke chamber 5. The air distribution mechanism 6 is connected to chamber A via channel 7, which exit into the cavity of housing 1 at the level of the annular channel 8 of the striker 3 in its most forward position (i.e., when it interacts with the tool 2). On the outer surface of the drummer 3, flats 9 are made, which, together with the inner surface of the casing 1, form channels 10, open into the annular groove 8 of the drummer 3 to supply energy carrier in the chamber. The upper end of the drummer 3 is made sealing on I. the compressed air device is equipped with a pipe 12, and a window 13 is provided for the exhaust. The device works as follows. At the time of launching, the impactor 3 contacts the tool 2, and the pro2 point 8 coincides with the exit-channels 7. At the same time, the compressed air through the nozzle 12, the air distribution mechanism 6, the channels 7, the groove 8 and the channels 10 enters the chamber 5. up until the lower edge of CA 11 opens the windows 13. When the drummer 3 rises, the air in chamber 4 is compressed, as a result of which the air distribution mechanism 6 switches the compressed air to chamber 4. The drummer 3 moves down and acts on the tool

2. From this point on, the work cycle is repeated. Claims of Invention A percussion device comprising a body with a cavity, a tool, a drummer with a sealing cattle and an annular groove, air-conducting channels arranged in the body, periodically informing the source. energy carrier with forward and reverse cameras, characterized in that, with a chain of operational reliability and simplification of the manufacturing technology of the device, the air inlet channels of the channel into the body cavity are made at the level of the annular groove of the striker in its extreme forward position, while the air inlet channels for The energy supply to the chamber of the return chorus is open in the annular groove of the drummer and formed between the inner surface of the body and the flats. Which are made on the outer surface of the drummer.
