    摘要: A reversible ground perforating device powered by a gaseous medium under ssure, comprising a hollow cylindrical body with a pointed front end. The body accommodates a hammer adapted to reciprocate therein. A front power chamber of variable volume is formed by the hammer in the body. The rear end of the hammer has a cylindrical hollow which forms a rear power chamber of variable volume. The power chambers are interconnected by means of ports provided in the hammer. A stepped cylindrical barrel is located inside the cylindrical hollow in the hammer and coaxially therewith. The barrel is secured in the rear end of the body and the large-diameter portion of the barrel is arranged to interact with the hammer. The wall of the large-diameter portion of the barrel has ports. A spring-loaded stepped sleeve is mounted coaxially with the stepped barrel so that the large-diameter portion of the sleeve is adapted to cover the ports in the barrel. The space between the large-diameter portions of the sleeve and barrel forms an annular chamber. Holes are provided in the sleeve small-diameter portion interacting with the barrel small-diameter portion. A ring is flexedly mounted in the large-diameter portion of the barrel in the front end thereof and coaxially therewith. The space between the ring, the inner surface of the barrel and the outer surface of the sleeve forms an auxiliary annular chamber. The annular chamber is in communication with the source of a compressed gaseous medium during forward movement of the ground perforating device, whereas the auxiliary annular chamber is in communication with this source during reverse movement of the device.

    摘要: An air-operated reversible percussive action machine comprises a housing (1) accommodating a reciprocating hammer (2). Secured inside the housing (1) is a stepped tube (5). The step of larger diameter of the tube (5) is received by a cavity (4) of the hammer (2) and has a port (12) for distributing air flow and feeding it to the interior of the housing (1). The tube (5) receives a sleeve (14) having a port (15) alternately communicable with the port (12) of the tube (5) in one of its two positions. One end face of the tube (5) has a projection (13) in the form of a sector of a circle, whereas the sleeve (14) is provided with a radial projection (16) so that in turning the sleeve (14) its projection (16) bears on one of the side walls of the projection (13) of the sleeve (5) thus assuming one of the two positions.

    摘要: A distinguishing feature of the present invention consists in that the menism for driving in rod-shaped elements into compact or frozen ground comprises a guide tube to accommodate said rod-shaped element. The tube extends throughout the length of the shell and is secured in the extension and the front portion of said shell, coaxially with the stepped ram and the shell. The outer surface of said guide tube contacts the inner surface of the axial hole in the stepped ram and has at least one channel which puts the rear and front working chambers in communication with each other when the stepped ram is in the foremost position, while the front portion of the shell is provided with a rigidly secured clamp for holding the rod-shaped element.

    摘要: The device comprises a hollow cylindrical body, pointed front at its end which device accommodates a striker forming the front working chamber in said body, and has a cylindrical space at its rear end. Said space receives an air-distributing and reversing mechanism, thus forming the rear working chamber. The air-distributing and reversing mechanism has a bushing which is fixed relative to the body, and an axially movable bushing, both bushings being arranged coaxially, spring-loaded in the axial direction relative to each other, and forming a chamber located in the front part of said mechanism, with the chamber communicating with a source of compressed air and intended to move the movable bushing during reversal of the device. The side wall of the movable bushing has a through hole and a longitudinal external recess, both made in such a manner that during the forward travel of the device the through hole places the chamber formed by the bushings in communication with the source of compressed air while during the backward travel the through hole is covered by the fixed bushing and the chamber formed by the bushings communicates with the atmosphere through the external longitudinal recess.
