Abstract

FIELD: building and road machines. SUBSTANCE: hydraulic percussion mechanism has a body with pressure passages, passages for draining, resetting, control and releasing, a striker with piston, lower and upper rods and bore, differential valve with lower and larger steps, installed in the body. The body, striker and valve form chambers for resetting, stroke, draining and control. Radial holes of pressure and drain are originated on lower step of the valve. The holes are used to open stroke chamber to hydraulic lines of pressure and drain periodically. Upper rod face of the striker and the body form together releasing chamber which is periodically gets open to control chamber when the striker in its lower position under negative pressure. EFFECT: simplified design of the distributing unit, higher reliability. 2 dwg

Изобретение относится к строительным и дорожным машинам, а именно к гидравлическим машинам ударного действия, и может быть использовано в горной, металлургической промышленности и т.д. Гидравлический механизм ударного действия состоит из корпуса с каналами напора, слива, взвода, управления и разгрузки, боек с поршнем, нижним и верхним штоками и проточкой, дифференциальный клапан с меньшей и большей ступенями, установленный в корпусе. Корпус, боек и клапан образуют камеры взвода, рабочего хода, слива и управления. На нижней ступени клапана выполнены радиальные отверстия напора и слива, периодически сообщающие камеру рабочего хода с гидролиниями напора и слива. Торец верхнего штока бойка с корпусом образует камеру разгрузки периодически сообщаемую в нижнем положении бойка при отрицательном давлении с камерой управления. Предлагаемые доработки позволяют существенно упростить конструкцию распределительного узла (клапана), исключить соударения и усталостное разрушение бойка и клапана и повысить надежность переключения клапана за счет гидравлической связи камер управления и разгрузки.The invention relates to construction and road machines, namely to hydraulic shock machines, and can be used in the mining, metallurgical industries, etc. The hydraulic mechanism of the shock action consists of a body with channels for pressure, discharge, cocking, control and unloading, a hammer with a piston, lower and upper rods and a groove, a differential valve with lower and higher stages installed in the housing. The body, the firing pin and the valve form the platoon, stroke, drain and control chambers. At the lower stage of the valve, there are made radial holes for pressure and discharge, periodically communicating the working chamber with pressure and discharge hydraulic lines. The end face of the upper stem of the striker with the body forms the unloading chamber periodically communicated in the lower position of the striker at negative pressure with the control chamber. The proposed improvements can significantly simplify the design of the distribution unit (valve), eliminate collisions and fatigue destruction of the hammer and valve and increase the reliability of valve switching due to the hydraulic connection of the control and discharge chambers.
