    摘要： A piston rod (2) with a piston (21), against which a displaceable valve ring (23), a short, axially rigid striking pin (3), guided in a bush (24), and a pressure transformer piston (25) are set, is immovably placed in one part of the supporting housing (1). A working tool (4) is placed in the second part of the supporting housing (1) in a tool bush (27) protected on the outside by a lower sealing cover (29) to prevent corrosion. A gas chamber (45) is set up under the supporting housing (1), the pressure transformer piston (25) and the striking pin (3). A pressure transformer cylinder (43) and an equalizing chamber (44) are formed between the piston rod (2) and the pressure transformer piston (25). The striking pin (3) is driven by working fluid under pressure, which is distributed by a system of channels in the piston rod (2). The striking pin (3) is driven onto the working tool (4) in a striking action by high-pressure gas, which is pressurized in the gas chamber (45). The movement of the striking pin (3) is controlled by a switching element (20), fitted in the piston rod (2), and a valve ring (23), pushed onto the piston rod surface. It is assisted by the pressure transformer, which eliminates pressure peaks of the working fluid.

    摘要： A breaching apparatus (100) includes an impactor element (106,108) and a self-contained energy source. The self-contained energy source (102) enables the impactor element (106,108) to impact a first surface of a structure. The impactor element is configured to transmit a localized shock wave through the structure upon impact. The self-contained energy source (102) is capable of accelerating the impactor element (106,108) to a velocity sufficient to induce spalling at a second surface of the structure. Multiple breaching apparatuses can be supported by a frame (704) to facilitate simultaneous or successive breaching of the structure. The breaching apparatus (100) can be used in a method to breach a concrete structure.

    摘要： Provided is a stepless variable auto stroke hydraulic breaker system capable of reducing impact energy reflected in the event of an idle blow by detecting a frequency of vibrations generated when a chisel breaks objects such as bedrocks using a vibration sensor (110), operating according to a short stroke if the frequency of vibrations does not exceed a preset frequency, and automatically switching the short stroke into a long stroke if the frequency of vibrations exceeds the preset frequency. The breaker system includes a vibration sensor (110) configured to detect vibrations generated when a chisel breaks rocks, a transmitter (100) provided with the vibration sensor and configured to transmit signals generated from the vibration sensor, a receiver (200) configured to receive the signals transmitted from the transmitter, and a stepless variable auto stroke hydraulic breaker controlled by a reception micro controller unit (240) of the receiver.

    摘要： An automatic shutoff system (70) for a hydraulic hammer (12) is disclosed. The automatic shutoff system includes an inlet groove (72) formed around a piston (42) associated with the hydraulic hammer and configured to receive pressurized fluid, and an outlet groove (74) formed around the piston associated with the hydraulic hammer and configured to discharge the pressurized fluid. The automatic shutoff system also includes an annular passage (78) configured to allow the pressurized fluid to flow between the inlet and outlet grooves. The automatic shut off system further includes a valve (86) disposed upstream of the inlet groove and configured to selectively block the pressurized fluid from flowing into the inlet groove based on an operational state of the hydraulic hammer.
