Description

The present invention relates to a device for handling, interlocking between them, guiding, driving, filing metal profiles or sheet piles of the type comprising a plate for mounting the device at the end of a hydraulic shovel arm, a frame integral with the plate, and an oscillating box mounted on the frame for mounting a threshing hammer movable relative to the frame, as known from document DE-A-3303262.

The object of the invention is to facilitate the handling and the positioning of the sections or sheet piles.

To this end the invention relates to a device for handling, interlocking, guiding, sinking, filing metal profiles or sheet piles, comprising a plate for mounting the device at the end of a hydraulic shovel arm, a frame integral with said plate, an oscillating box mounted on the frame (2) for mounting a threshing hammer movable relative to the frame, characterized in that it comprises a 360 ° rotation clamp fixed to said frame and capable of grasping and maintaining the profiles by their wings, at any point of their lateral edges, and a folding telescopic boom articulated at the top of said frame and guiding the movement of a sliding carriage supporting a mounting plate for said hammer.

Advantageously, there will be placed under the frame a safety device which, in its front position, prevents inadvertent sliding of the sections or sheet piles.

The device of the invention operates by using as an energy source that of the shovel which carries it and therefore comprises a plate which allows its mounting on the arm of the hydraulic shovel, which gives it the same possibilities of movement as a bucket. .

On this device, by means of the frame, is fixed a clamp which is placed horizontally, front face below, on a stack of profiles, in any part of the length thereof. The jaws of the pliers are then actuated. By this fact, they press the profile to be lifted, by acting on its wings, against a die, which prevents them from moving. The profile is then raised horizontally in front of the hydraulic shovel. A rotation of ninety degrees of the orientation system supporting the clamp, allows it to be placed vertically. Threshing can then begin, except in the case of sheet piles whose foot is placed on the ground, while slightly loosening the clamp, which causes the device to slide to the bottom thereof. The jaws are tightened on the locks. The safety device placed under the clamp, pushed by its operating system, slides forward and is placed under the sheet piles, to prevent inadvertent sliding. These, held vertically by their lower part, are then raised to the level of the top of the curtain already in place and their lock engaged in the sheet pile lock previously plugged.

At the start of engagement, the downward movement is accompanied by the clamp until the jaw support comes into contact with the top of the curtain. Tightening ceases at this time and the sheet pile slides to the ground under the effect of its own weight.

The clamp, held in this position, adjusts the verticality and alignment, preventing any deviation at the start of threshing.

The latter begins by bringing it into a vertical position, by its lifting device, of a telescopic boom, articulated at the top of an oscillating box, the axis of which is aligned with the axis of rotation of the clamp. The folding or unfolding of the boom then adjusts the height of the hammer and places it on the profile to be beaten, maintaining pressure during striking. A complementary device controls the sliding of a carriage which carries the adaptation piece of the hammer and extends this action until the slide reaches the foot of arrow, while maintaining vertical pressure on the profile. When the hammer's anvil reaches the level of the first die, the clamp is tilted by 90 °, authorizing the continuation of the threshing until the sheet pile heads reach the desired level.

The device shown in Figures 1 to 5 as a whole, comprises a plate (1) welded to a frame (2). This consists of two strong sheets (3) spaced about 30cm apart and joined together by three spacers (4) of the same kind. Two verticals are placed at the lateral ends; the other horizontal is placed at the base of the previous ones.

The frame, seen from behind in Figure 2, has in its upper part, the shape of a semicircle and in its lower part, that of a rectangle about two meters long.

The rear part of the frame is similar to the previous one, truncated from its part in a semicircle.

The front face circumscribes an orientation ring (5), driven in rotation by the pinion (6) of a hydraulic motor (7), placed in the free space provided between the two faces of the frame.

The fixed part of the crown is bolted to the frame. The movable part, with a total rotation of 360 °, drives in its movement a sheet (8) which supports the clamp (40) for gripping the sheet piles.

This, according to Figures 5 to 7 consists of two crosspieces (9) made of square tube, on which slide four jaw supports (10) opposite two by two on each crosspiece.

The supports can be immobilized on the sleepers, using pins (11), introduced into the bores which pierce them right through.

Each support consists of a square tube sliding around that of the cross member, on the side faces of which are welded two trapezoidal sheets braced. Between these sheets is housed a jaw (12), having the shape of a portion of a circle which rotates about an axis (13), passing through it and the two lateral sheets of the support.

The jaw rotation movement is controlled by a small telescopic cylinder (14) whose head is articulated on the part lower jaw and lower body on a sill in H profile (15), welded to the longitudinal axis of symmetry of the clamp. The other end of the jaw protrudes from the radius of the circle portion and forms a jaw whose contact face with the sheet pile locks is striated.

Between the jaw supports taken two by two, is fitted into three slides (16), a crosspiece of about twenty centimeters in width, having the shape of a sheet pile matrix.

The profile of this inscribed in its hollow part, the external face of the sheet pile of the largest module, while its convex part is inscribed in the internal face of the sheet pile of the smallest module of the series to be used, as shown in Figures 8 to 11.

On the edges and in the middle of the matrix, in the case of pairs of sheet piles, are provided plates (17) at the location of the locks.

These dishes play the role of the gripper's sleeping jaw.

Two of the above-mentioned slides are arranged on the internal side of the supports of the movable jaws, the third being the H-shaped section already used as the support base for the jaws jacks.

The jaws can be immobilized in rotation by the installation of a second spindle in another bore (18), which, after removal of the dies, makes it possible to adjust the spacing of the supports, using the clamping jacks .

A variant shown in Figure 7 shows the clamp equipped with elongated jaws which allow to grip and move horizontally a pile of sheet piles during unloading or distribution on site.

In the space arranged between the two faces of the frame, an oscillating box (19), represented by FIGS. 12 to 14, is movable around an axis (20), the center of which is aligned with that of the crown orientation, which allows it to tilt approximately 15 ° on either side of its vertical axis, under the effect of a jack (21), articulated under its underside on the one hand, on a vertical spacer of the built, on the other hand.

This box, made up of welded sheets, is reinforced at the location of the axis of oscillation on each of its faces by a sheet (22), as well as on a part of the surface of its sides, by a plate of strong sheet (23). Its upper part is extended so as to be able to receive a bore which will serve for the passage of the axis of rotation (24) towards the rear, of the telescopic boom (41). The rigidity of the box is improved by sheets parallel (25) to its base, welded inside of it and three in number.

The front part of the box which appears in Figure 12 in cantilever, presents from behind in Figure 13, a curved shape to the diameter of the slewing ring on which three rollers (26) are supported, in order to limit the stresses in the angle formed by the box.

At the rear of the box is welded an ear, on which is articulated by an axis, the jack (27) which controls the reversal of the telescopic boom. According to Figures 15 to 17, it consists of a lower part in which slide the two rectangular sections (28) constituting its upper element. This slides has the shape of a rectangle of welded sheets, the widths of which are the sides. The front face (29) reserves an opening over its entire height, except for a spacer at the head and one at the bottom which maintain the spacing on both sides. A space of a few centimeters is reserved between the rear face and the slide, by means of a plate (30) welded on the internal face of this sheet and at its upper part, as well as a plate (31) of the same dimension welded at the rear of the slide at its lower part, which thus completes the role of the spacer which fixes its spacing. This is provided in the upper part by a bracket (32) which has a cantilever of about thirty centimeters on the front of the boom.

The two plates have a function of stopping the sliding of the two elements. This movement is due to the action of two telescopic cylinders (33) each housed in a beam of the upper element, articulated at their base on the axis of reversal of the boom and at their top, on an axis crossing the two from side to side.

A H-shaped carriage (34) of approximately 50cm in height slides on these two beams. The soul of this H is placed between them. The wings are at the back and at the front. The rear wing is housed in the void formed between the slider and the boom slide, while the narrower front wing fits into the opening on the front face.

This construction method allows it to run from the bottom to the top of the boom in the deployed position. This slide is assembled in a removable manner and on its front face, it carries two vertical gussets (35), on either side of the vertical axis of the assembly.

These gussets are bored to allow the passage of the two mounting pins of the plate supporting the threshing hammer.

An additional bore (36) recessed from the previous ones, receives an axis located at the top of the body of a jack (37), the head of which is articulated under the jib head jib.

This cylinder controls the sliding of the carriage.

Under the clamp frame, two Tees (38) appearing in FIGS. 5 and 6, slide by their wings in two slides formed by two angles with unequal wings and pushed simultaneously by a jack (39) placed between them, they come slide under the sheet piles held vertically, in order to avoid accidental sliding of these between the jaws.

The device is particularly intended for handling, guiding and filing sheet piles and other sections, on public works or building sites.
