B23k 9/12 U.S. Cl. 219125 7 Claims ABSTRACT OF THE DISCLOSURE A full-automatic welding device for jointing concrete pile sections with steel end plates in the forming of piles at a work site. It comprises a hinged annular frame fittable to the pile being formed and a welder unit mounted on the frame and adapted to travel along its periphery while welding together the adjacent end plates of concrete pile sections. The device is featured by its different functional parts and their arrangements.
This invention relates to automatic welding devices and more particularly to those designed to joint endwise a plurality of concrete pile sections each having at either end a structure including a steel end plate and a tubular steel band connected therewith.
In usual practice, foundation piles, each including a plurality of such concrete pile sections, are formed by the procedure including the steps of placing a concrete pile section on the one previously struck into the ground with their adjacent end plates in aligned contacting relation to each other, connecting the end plates by electric-arc welding along the annular groove formed between the peripheral portions of the aligned end plates in the plane of their contacting end surfaces, and then striking the pile sections thus connected into the ground. Obviously, this procedure is repeated as desired to obtain a total pile length appropriate to the ground and the entire process including the welding operation is principally performed at the site of pile foundation.
The present invention has for its object to enable such welding operation to be performed in a fully automatized fashion.
Another object of the present invention is to enhance the efliciency of the process of successively jointing standardized concrete pile sections.
A further object of the present invention is to provide an automatic welding machine operable to form a welded joint of improved quality between the adjacent ends of two successive concrete pile sections at all times with a definite uniformity.
These and other objects, features and advantages of the present invention will become more apparent from the following description when taken in conjunction with the accompanying drawings, which illustrate some preferred embodiments of the present invention and in which: v

FIG. 3 is an enlarged side elevation of the welder unit of the machine;
FIG. 4 is a rear elevation of same;
FIG. 6 is a side elevation, partly in section, of the welder unit;
FIG. 7 is a side elevation showing a modification of the mounting frame;
FIG. 7a is a cross-sectional view substantially taken along the line 7a7a in FIG. 7;
FIG. 8 is a side elevation illustrating the manner in which the welder unit of the invention is used for jointing concrete pile sections in inclined position;
FIG. 9 is a side elevation partly in section, of a modified form of the welding-wire feed mechanism; and
FIG. 10 is a side elevation showing a modification of the adjustable welding-torch support mechanism.
Description will next be made of the features of the full-automatic welding device, designed according to the present invention, and particularly of the structure of the different functional parts of the device.
MOUNTING FRAME The welding device has a mounting frame A designed to support the device on the concrete pile section previously struck into the ground. The mounting frame A is made in two halves hinged together at 7 and thus can readily be fitted onto the top end portion of the concrete pile section P to which another concrete pile section P is to be jointed. At their free ends, the half frames are connectible with each other as by hook means 1 to form an annular ring, embracing the pile section P on which the frame is fitted.
The mounting frame A is provided with an annular guide rail 2 for guidingly supporting guide rolls 5 carried on the welder unit, which is to be described hereinafter in detail, and a ring gear 3 in mesh with a drive pinion 6 also carried on the welder unit for its travel along the annular frame A. It will be apparent to those skilled in the art that both guide rail and ring gear are made in two halves carried on the respective half frames and complete their respective annular forms when the frame is closed on the pile section.
The mounting frame A is also provided with means for enabling the frame to be supported on the pile section in a correct position such that at all its circumferential points the frame is radially equally spaced from the periphery of the pile section and lies at the same height or in a plane at right angles to the pile axis. By this means, once the tip of the welding torch is properly set opposite the peripheral edge of the adjoining contacting surfaces of the pile end plates E and E it remains in a correct position relative to the annular peripheral groove defined between the end plates E during the travel of the Welder unit along the periphery of the mounting frame. Such means for supporting the mounting frame A in the correct position described above includes a number of adjusting bolts 4 carried by the frame and extending radially thereof. As will readily be understood, the frame can be readily centered relative to the pile section P by the adjustment of the bolts 4 to provide a uniform radial space between the frame and the periphery of the pile section P. The height of the frame or its position axial to the pile section is determined by placing the ends of the adjusting bolts 4 in engagement with appropriate positioning marks carried on the tubular reinforcing band B welded to the end plate E, for example, recesses b previously formed in the band.
TRAVEL MECHANISM OF THE WELDER UNIT The welding unit includes a travel mechanism Which comprises a drive motor 16, a drive pinion 6 adapted to be driven from the motor through an appropriate speed reducing mechanism, a guide roll or rolls held in rolling engagement with the guide rail 2 of the mounting frame A and cooperable therewith to guidingly support the welding unit thereon, and a pair of rubberized abutting rolls 14 engageable with the peripheral surface of the concrete pile section to hold the welder unit in an upright position under gravitation, which tends to tilt the welder unit as suspended on the guide rail 2 by roll means 5 toward the pile section. The guide roll means may include a single roll but it is preferable to provide a pair of guide rolls 5 as shown thereby to impart a greater stability to the welder unit while avoiding any undesirable concentration of the gravity load in the area of rolling engagement. The same holds with the abutting roll means 14. In order to accommodate varying diameters of concrete pile sections used (in practice, sized, for example, 450 mm. or 400 mm. in diameter), the guide rolls 5 are made adjustable in their mounting angle and in position on their own respective axes and the abutting rolls made adjustable in position on their own respective axes.
Further, for convenience when the concrete pile is struck in an inclined position, the travel mechanism may include two pairs of abutting rolls arranged at the top and bottom of the unit, for example, as shown in FIG. 8 at 14 and 14a.
WIRE FEED MECHANISM OF THE WELDER UNIT Provided on the welder unit W is a wire feed mechanism including a drive motor 16 for operating the mechanism, a speed reducer 17, a feeder 18, wire guide cable 19, and a wire reel 20. The feeder is comprised of a pair of opposing feed gears 18, which are driven through the speed reducer 17 from the drive motor 16, which takes, for example, the form of a D0. servomotor. In operation of the feed mechanism, the welding wire M from the wire reel is drawn through the interior of the follow wire guide cable 19 and, passing between the opposing feed gears 18, is forced out through the welding torch T. As shown in FIGS. 3, 5 and 10, the wire reel 20 is incorporated in a compact form within the welder unit W, but it may conveniently be arranged on the ground, as shown in FIG. 9.
WELDING-TORCH SUPPORT MECHANISM The welding torch T of the welder unit must be mounted thereon in such a manner that it can be adjusted in its mounting angle as well as in its vertical position thereby to enable it to correctly position the tip of the welding wire M relative to the annular groove as formed between the adjoining end plates of the concrete pile sections being jointed. To this end, the welding torch is supported by a structure including a handle 23 for angular adjustment and another handle 24 for vertical adjustment, as shown in FIGS. 3 and 5. Through the welding torch T with such supporting structure may be formed integrally with the welding wire feed mechanism described above, it is rather desirable for convenience in practice and par
