    Abstract: A moving-rotating linear covering tool, comprising a port, a primary oil cylinder, a piston rod, a rear end cover, a base sleeved on the right end of the primary oil cylinder, and a handle fixedly connected onto the outer cylinder of the base. The port is fixedly connected to the left end of the primary oil cylinder, the center thereof being provided with a circular hole that clearance-fits the piston rod arranged in the primary oil cylinder. A circular flange of the rear end cover is fixedly connected onto the right end face of the primary oil cylinder. The base is connected to a guide supporting sheath sleeved, in a clearance-fitted way, on the outer cylinder of the primary oil cylinder. A bearing seat is provided on the right end wall of the base Two screw holes are symmetrically provided at the right end face of the rear end cover.

    Abstract: Disclosed is a crosshead component of a large diesel engine. The crosshead component consists of a crosshead pin (1), slide blocks (2), wear-resisting plates (3), sealing covers (4), and a sleeve (5), and has a structure with H-shaped cross and longitudinal sections. The crosshead pin (1) is a cylinder provided with petal-shaped through holes. The slide blocks (2) are respectively fitted on and connected to outer circles of left and right ends of the crosshead pin (1). The sleeve (5) is inserted in and connected to the petal-shaped through holes (112) of the crosshead pin (1) to form oil inlet/return way cavities. Left and right end surfaces of the crosshead pin (1) are respectively connected to the sealing covers (4) for sealing the oil way cavities. Front and back ends of the slide blocks (2) are respectively connected to the wear-resisting plates (3). The crosshead component has excellent interchangeability, economy and convenience.
