摘要： The invention relates to a method for making underwater steel ducts (1) that comprises assembling end to end by welding the ends of unitary duct members (2a-2b), the steel or metal alloy welding seams of said welds being located outside the duct, characterised in that a localised hammering is carried out inside the duct in order to increase the steel or metal compression at said welds (6) and on the peripheral inner surface (2i) of the adjacent duct on either side of the welds (6) in order to create a corridor (7) with a hammered surface on a limited distance L in the longitudinal axial direction (XX) of said duct. Preferably, the hammering is carried out with a device that comprises a carriage with wheels (3) equipped with a hammering tool (5).

摘要： Rock breaking apparatus includes a guide column (112) within which a weight (12) falls under gravity to strike a tool (134). A piece (146) of shock-absorbing material is located at or near the base of said column such that it enables force to be transmitted from said weight (12) to the tool (134), whilst minimising the effects of the impact of said weight (12) on other parts of the apparatus. The piece (146) of shock-absorbing material has an aperture therethrough, for the passage of the tool (134). The tool (134) may have a recessed portion (140) which co-operates with a retaining pin (144) located substantially at right angles to the direction of motion of the tool (134). The apparatus may also have operating means, including means for raising a weight, means for holding a weight in one of a number of positions and means for allowing said weight to fall.

摘要： A tool assembly (4) for working a material (R) such as breaking rock. Assembly (4) includes a tool mounting (17) having a fixed section (18), and a movable section (19) for movement relative to the fixed section (18) in a working direction (DW) and an opposite return direction (DR). A tool (34) is mounted on the movable section (19) for movement relative thereto in the working direction (DW) and return direction (DR). Limit means (49, 50) on tool (34) limits relative movement between tool (34) and movable section (19) to between a tool operative position and a tool operated position. During a working stroke, tool (34) is engaged with material (R) and moved in working direction (DW) from the operative position to the operated position and thereafter in unison with the movable section (19) under action of a working force applied to tool (34) thereby to work material (R). The tool assembly (4) also includes biasing means (29) acting between the fixed section (18) and movable section (19) to absorb the applied tool working forces transferred from tool (34) to the movable section (19), and also to provide a restoring force to the movable section (19) for returning the movable section (19) in return direction (DR) upon conclusion of the working stroke of the tool (34).

摘要： A vibratory impact hammer including a hammer body assemblage suspended by rubber mounts for reciprocal axial movement in a support frame, the rubber mounts providing guiding and damping action of the assemblage in either direction of axial movement without extraneous friction forces acting thereupon, and a pair of synchronously driven eccentric weights which are arranged to provide vibratory movement of the assemblage.

摘要： A recoil damper (10) for a reciprocating member (12) mounted in a housing (24) includes a annular ring (38, 138) mounted adjacent a shoulder (28) formed on the reciprocating member, the annular ring (38, 138) mounted in a viscous fluid interior of the housing. The annular ring (38, 138) cooperates with the shoulder (28) of the reciprocating member (12) to allow a relatively free flow of the viscous fluid around the shoulder (28) upon motion of the reciprocating member (12) in one direction and to restrict flow of the viscous fluid around the shoulder (28) upon motion of the reciprocating member (12) in the other opposite direction.

摘要： Provided is a nail gun. The nail gun includes: a housing formed with an accommodating space; a cylinder connected to the housing and used for storing gases; a firing assembly at least partially disposed in the cylinder and capable of moving from an initial position to a firing position in the cylinder to drive a nail out; a power output assembly disposed in the accommodating space formed by the housing and used for outputting a driving force to drive the firing assembly to move in the cylinder; and a drive wheel connected to an output shaft of the power output assembly and used for driving, under the drive of the power output assembly, the firing assembly to move in the cylinder. The drive wheel has a first drive tooth and second drive teeth, where the radius of the addendum circle of the first drive tooth is less than the radius of the addendum circle of a second drive tooth, the first drive tooth is a drive tooth disposed at a start end of the drive wheel, and the first drive tooth meshes with the firing assembly when the drive wheel starts driving the firing assembly to reset.
