Definitions

  • the mounting surfaces are formed in an approximate quadratic or rectangular cross-section and is provided on all four sides with similar mounting positions or places to which the guide elements can be fastened.
  • the lower section of the body can be turned on its longitudinal central axis, in 90 angles so as to be connected to the supporting standard in at least four positions 8 Claims, 2 Drawing Figures 1 MEANS FOR MOUNTING RAMS OR PILE DRIVERS
  • the present invention relates to a Diesel and/or internal combustion assisted pile driver or ram and in particular to the mounting thereof in connection with a vertical supporting standard.
  • Diesel-assisted or internal combustion assisted pile drivers, hammers, or the like are well known.
  • such apparatus comprises a housing mounted to be adjustable and/or movable on a vertical standard or scaffold.
  • the housing defines a ram cylinder having a precussion piece at one end adapted to strike the pile or other work piece and ram piston movable to strike the percussion piece.
  • the ram piston is generally lifted by a hoist or other pulley system and allowed to drop on the percussion piece.
  • a combustion fuel is sprayed into the cylinder and is compressed by the downwardly moving ram piston until it explodes. The explosion forces the percussion piece with greater force onto the pile or'workpiece while simultaneously lifting the ram piston upwardly, preparatory to another cycle.
  • rams of this type are generally movably mounted on a vertical standard and to this end the pile driver housing has suitable slidable guide elements connected to it.
  • stress of the working lever often causes the guide element to twist and become deformed, damaging the seat or position on the cylinder housing to which it is attached.
  • a diesel assisted or internal combustion type pile driver or ram having at least an upper section and separable lower section is provided with a plurality of mounting surfaces on its lower section and connecting guide elements.
  • the guide elements are elongated bracket members removably secured to the mounting surfaces at one end and so as to be connected to the supporting standard in at least four positions.
  • the mounting surfaces may be machined on the surface of the ram cylinder, or they may be made by angle piece brackets welded to the surface.
  • the guide elements may be brackets which are permanently attached to each of the mounting surfaces or they may be removable. In either case, however, even with the damaging of one or more of the guide elements, the lower section may be easily repositioned, to present a new mounting position to the standard.
  • FIG. 1 is a vertical side view of a vertical supporting standard on which a diesel type ram is mounted;
  • FIG. 2 is a sectional view taken along line 2-2 of FIG. 1.
  • FIG. 1 there is shown a side view of the apparatus comprising a vertical supporting standard or frame generally depicted by the numeral 10 comprising a pair of parallel spaced poles 12 (formed of tubular pipe or stock material) on which a diesel or other internal combustion pile driver, generally depicted by the numeral 14 is supported; the upper end of which being secured to a carriage l5 fitting over the pipes 12.
  • the pile driver or ram comprises a body housing having upper section 16 and a lower section 18 in axial end relationship and which is removably secured by mating flanges 20 and 22 which are fastened together by removable bolts 24.
  • a plurality of inlet and/or exhaust openings 26 are provided radially about the lower section 18 leading from its interior, while an injection tioned copending applications and patents there are shown various details of rams which may themselves be utilized in the device shown here.
  • each end of the lower section 18 of the ram cylinder housing 18 there is provided four mounting surfaces comprising flanges 30 arranged in a set uniformly radially about the circumference.
  • the respective mounting flanges 30 at each end are arranged in axial planes transverse to the central axis so that four pair of upper and lower mounting flanges 30 are provided.
  • the mounting flanges are right angle corner pieces as seen in FIG. 2 and have perpendicular flat faces on two sides so that in combination the four members of each set form a quadratic (square or rectangular) configuration proscribed about the circumference of the lower cylinder section 18. They are uniformly symmetrical from all sides about the central axis of the lower section.
  • the mounting flanges 30 are adapted to be fastened pairwise to a lower guide brackets 32 and upper guide brackets 34 which themselve clamp onto each of the vertical poles 12.
  • the guide brackets 32 and 34 may be secured to the mounting plates on any one of its four sides.
  • the mounting flanges are provided with threaded holes 36 in which conforming bolts 38 or other suitable fastening means are inserted. It will thus be obvious that for each rotation of the lower section of only 90 about its central axis, a new mounting position is obtained.
  • the guide brackets 32 and 34 are similar in construction and as seen in FIG. 2 comprise an elongated arm which at the rear end of is formed as a semi-circular hasp adapted to partially encircle the pole l2, and at its front or the other end is adapted to be contiguous with the mounting plate and which is itself provided with suitable holes through which the bolts 38 extend.
  • the guide bracket is shaped so that when securely fastened to the mounting plate, the rear semi-circular hasps of each transverse pair squeeze against the poles 12 in jaw-like fashion to hold the lower section in place for the proper guide arrangement.
  • the hasps may be provided with suitable slide inserts.
  • the guide elements (brackets 32 and 34) and the mounting flanges 30 may be varied or modified from that shown without departing from the present invention.
  • all four sides of the lower section 18 may be initially provided with guide elements.
  • the guide elements and the supporting frame for guiding the ram pile driver may also be formed so that for each position at which the ram cylinder is guided only one guide element is necessary.
  • the position of mounting flanges on the lower section 18 can be modified and they may be placed in other relative axial or radial areas, than those shown.
  • mounting surfaces or plates and guide elements brackets be such that for any one of the sides, of the lower cylinder section 18 presented to the supporting frame 12, that the lower section be fully capable of being supported and guided. Since the mounting surfaces are similar, only one type of guide element is necessary.
  • the arrangement of several injection pumps about the cir cumference of the ram body is possible without the necessity of providing the several slots in the body for the activation of the pump. Since by rotating the lower cylinder portion of the ram body relative to the upper portion the pump may be positioned at any one of the inlet/exhaust openings on the respective four sides. Therefore, the upper part of the ram body can remain in its fixed position relative to the vertical standard. This is essential since the vertical standard is provided with a movable trolley carriage having a nose which enters into a slot in the upper part of the ram piston so as to cause the piston to raise or boost the ram.
  • the mounting surfaces may be directly machined on the cylinder 18; however, it is self-evident that the lower portion of the ram body need not be square or quadratic along its entire length. It is also not necessary to make the entire circumference lie in a square or rectangular cross-section but only those surfaces to which the guide elements are actually secured. Lastly, it will be understood that the lower portion of the ram body can be made in several parts which are fastened or secured together.
  • a diesel/internal combustion assisted pile driver, ram or the like comprising a body having at least an upper section and a separable lower section, said lower section being provided with at least one guide bracket for connection to a vertical standard, mounting surfaces formed on the lower section in a uniform quadratic cross-section, means for fastening said guide bracket on the mounting surfaces of a selected one of the four sides, whereby said lower section may be fastened relative to the upper section in at least four positions at intervals.
  • Apparatus according to claim 1 including at least two inlet/exhaust means formed about the circumference of said lower section, said inlet/exhaust means being adapted to selectively mount a fuel injection pump in association with a selected side.
  • means for mounting said lower section to a vertical standard comprising a plurality of mounting surfaces arranged in a set uniformly about the circumference of the lower section in a plane transverse to the central axis and at least one bracket associated with said set, said bracket being adapted to be connected at one end to said standard and to be secured at the other end to a selected one of said mounting surfaces whereby the position of said lower section may be varied relative radially to said central axis.
