    摘要： The present invention relates to a method of securing a shaft at any point along its substantially vertical axis of movement, wherein the method includes a locking device that is moveable with respect to the shaft. The method is characterised by the step of moving the locking device into a position wherein at least one face of the locking device mates against at least one point on the shaft so as to secure the shaft at any point along its substantially vertical axis of movement. In particular this invention relates to a method of securing a drop hammer at any point along its substantially vertical axis by use of a hydraulically controlled cam.

    摘要： A rock drill (1) comprises a frame (6), a percussion member (2), an axial shank (3), and an axial sleeve (5) provided within the frame (6) and comprising a first pressure surface (8) provided in a first pressure space (7) and a second pressure surface (10) provided in a second pressure space (9). A first channel (11) is provided in the axial sleeve (5) for providing a connection between the first pressure space (7) and the second pressure space (9) in at least one position of the axial sleeve (5) in the frame (6). A second pressure channel (13) connected to the second pressure space (9) is connectable to external pressure. A pressure accumulator (14) is connected to the first pressure space (7) and the flow of the pressure medium outwards from the first pressure space (7) is throttled.

    摘要： A method and device for converting rotary motion to reciprocating percussion motion. The device comprises a machine body (4), a travel portion (7), and a reciprocating percussion portion (5). The reciprocating percussion portion (5) comprises a percussion drive mechanism (2), a rocker arm (6), and a percussion head (1). The percussion drive mechanism (2) comprises a percussion power source member (11), a transmission component, and a crankshaft (10). The percussion power source member (11) comprises a motor, and the motor comprises a power output shaft (14). The transmission component comprises a power gear (13) and a transmission gear (12). The power gear (13) is mounted on the power output shaft (14). The transmission gear (12) drives the crankshaft (10). The transmission component comprises a transmission shaft. The power output shaft (14) is perpendicular to the rocker arm (6), and is parallel to the transmission shaft and the crankshaft (10) so that the transmission gear (12) drives the crankshaft (10) to convert rotary motion to reciprocating motion; or the power output shaft (14) is parallel to the rocker arm (6), the crankshaft (10) is driven to convert rotary motion to reciprocating motion after the power direction is changed by a power bevel gear and a transmission bevel gear. The crankshaft (10) drives the percussion head (1) to perform reciprocating percussion. The travel portion (7) drives the machine body to travel. The machine body (4) drives the reciprocating percussion portion (5) to move and work continuously. The device applies to the mining field or mechanical engineering field, and has advantages such as strong structural strength and a small amount of maintenance.
