В каждой секции имеютс входна 11 и выходна 12 камеры и дросселирующее устройство , состо щее из втулки 13 и подпружиненного клапана 14 с отверсти ми 15. Клапан закреплен на штоке 16, на котором установлены пружины 17 и 18 и гайка 19. Торцы секций закрыты крышками 20. На концах штоков 16 установлены подвижные блоки 21, которые посредством бесконечной гибкой т ги 22 св заны с неподвижными блоками 7.The expander includes a housing 1, a pilot pilot 2, a set of pneumatic impactors 3 evenly placed in the housing with working chambers 4 and pistons 5, an air distributor 6 with fixed blocks 7 and feed sections 8, 9, 10. Each section has an inlet 11 and an outlet 12 of the chamber and a throttling device consisting of a sleeve 13 and a spring-loaded valve 14 with openings 15. The valve is fixed on the stem 16, on which springs 17 and 18 and nut 19 are mounted. The ends of the sections are closed with caps 20. At the ends of the rods 16 are mounted moving blocks 21, cat These are connected to fixed blocks by means of an endless flexible gigi 7.
Расширитель скважин работает следующим образом.The expander wells works as follows.
Расширитель устанавливают на забой, включают вращение и подают сжатый воздух в воздухораспределитель 6.The expander is installed on the bottom, include rotation and serves compressed air into the air distributor 6.

Сжатый воздух из входной камеры 11 каждой подвод щей секции 9,8, 10 через отверсти 15 подпружиненного клапана 14 и зазор между последними и втулкой 13 поступает в выходную камеру 12 и затем соответственно в рабочую камеру А каждого из комплекта пневмоударников 3, привод в возвратно-поступательное движение поршень 5, под действием которого осуществл ют разрушение породы..Compressed air from the inlet chamber 11 of each inlet section 9.8, 10 through the openings 15 of the spring-loaded valve 14 and the gap between the latter and the sleeve 13 enters the output chamber 12 and then respectively into the working chamber A of each of the set of air hammers 3, the return drive translational movement of the piston 5, under the action of which the destruction of the rock is performed ..
При равномерной работе пневмоударников 3 зазор между подпружиненным клапаном 14 и втулкой 13 дросселирующего устройства каждой из подвод щих секций 8, 9, 10 одинаков и, следовательно, в рабочую камеру 4 каждого пневмоударника 3 поступает равное количество сжатого воздуха при одинаковом давлении.When the hammers 3 are evenly operated, the gap between the spring-loaded valve 14 and the sleeve 13 of the throttling device of each of the supply sections 8, 9, 10 is the same and, therefore, an equal amount of compressed air is supplied to the working chamber 4 of each hammer 3.
Если же равномерность работы пневмоударников 3 нарушаетс вследствие воз- можных деформаций поршн 5, изменений температурного режима пневмоударников 3 или других факторов, то зазор между подпружиненным клапаном 14 и втулкой 13 измен етс пропорционально сопротивлению потребител . Если, например, сопротивление потреблению сжатого воздуха пневмоу- дарником 3, св занным с подвод щей секцией 8, увеличилось, то расход воздуха там уменьшилс и давление в выходной ка- мере 12 возросло, а в выходных камерах 12 секций 9 и 10 расход сжатого воздуха и скорость его движени мгновенно возрастают , что вызывает перемещение клапанов 14If the operation of the hammers 3 is disturbed due to possible deformations of the piston 5, changes in the temperature regime of the hammers 3 or other factors, then the gap between the spring-loaded valve 14 and the sleeve 13 changes in proportion to the resistance of the consumer. If, for example, the resistance to the consumption of compressed air by a pneumatic air distributor 3 connected to the inlet section 8 has increased, the air consumption there has decreased and the pressure in the output chamber 12 has increased, and in the output chambers 12 sections 9 and 10 the compressed air consumption and the speed of its movement increases instantaneously, causing the valves to move 14
в направлении камер 12 в подвод щих секци х 9 и 10, уменьша зазор между подпружиненными клапанами 14 и втулками 13 упом нутых секций. С помощью бесконечной гибкой т ги 22, огибающей неподвижные 7 и подвижные блоки 21, клапан 14 перемещаетс в сторону увеличени зазора в подвод щей секции 8, что автоматически восстанавливает равномерную работу всех пневмоударников 3.in the direction of the chambers 12 in the supply sections 9 and 10, reducing the gap between the spring-loaded valves 14 and the sleeves 13 of the said sections. With the help of endless flexible traction 22, the envelope of the fixed 7 and movable blocks 21, the valve 14 moves in the direction of increasing the gap in the inlet section 8, which automatically restores the uniform operation of all air hammers 3.
