Fig. 9 is a view corresponding to Fig. 1 of a device for driving piles or the like into the ground with a modified design.

The drawing shows a device 1 for driving piles 2 or the like, in particular relatively long vineyard piles 2 into the ground. This device has a guide frame 3 , which is equipped with several, for example three legs 4 . The guide frame 3 has an essentially flat table 5 , which according to FIG. 3 can have an approximately trapezoidal plan. On this table 5 , an upwardly projecting slide guide 6 is rigidly mounted, which consists of two rails 7 running parallel to one another at a distance.

Between the two rails 7 of the sliding guide 6 , a pile holder 9 can be inserted from the side, also through a slit 8 in the table top 5, so that the two rails 7 lie approximately diametrically opposite on the circumference thereof.

The pile holder 9 consists of a pile 2 to be driven in at least partially around its profile, namely a tube which is provided over most of its length with a slot-like opening 10 , the width of which is larger than the largest cross-sectional dimension of the piles to be driven 2nd

Following the upper end of the slot-like opening 10 , the pile holder 9 has in its interior a transverse support stop 11 with which it can act on the upper end 2 a of the pile 2 , as can be clearly seen in FIG. 7.

Above the support stop 11 , the pile holder 9 is provided with a load weight 12 , which in the exemplary embodiment shown consists of a solid Endab section of the pile holder itself, which of course can also be formed by a special element connected to the pile holder 9 .

From Fig. 6 it can be seen that the pile holder 9 or the tube which forms it and is provided with the slot-like opening 10 has a round cross section. The pile holder 9 can, of course, also have any other cross-section that is suitable for accommodating the pile 2 to be driven in its interior.

The stake holder 9 operates with two at its periphery removably engaging jaws 13 together, as shown in Figs. 1, 3 and 6 is clearly visible.

Each of these jaws 13 is articulated via a rearward, rigid cantilever arm 14 to a joint 15 which is located at the lower end of a column 16 . This is slidably guided in a housing 17 in the upward direction. As can be seen in FIGS. 4 and 5, a spring element 18 , for example a strong compression spring, is seated inside the housing 17 . The biasing force of the spring element 18 within the housing 17 can be varied by an actuator 19 . On the other hand, the spring element engages on a collar 18 so 20 of the plunger 16 to that it tends to hold the plunger 16 in its lower end position, which can be seen in each of FIGS. 1, 2 and 4.

The clamping jaws 13 are profiled in a prism shape and are also designed such that each of them comprises one of the rails 7 of the sliding guide 6 on three sides, as can be clearly seen from FIG. 6. In order to make this possible, each jaw is equipped with a longitudinal groove 21 which interacts with the rails 7 as a side guide for the jaws 13 . On both sides of the longitudinal groove 21 , each clamping jaw 13 has a cheek 22 , the free ends of which have a profile which is matched to the cross-sectional shape of the pile holder 9 . In addition, the free end faces of these cheeks 22 are each provided with a support 23 made of friction-increasing material, as can also be seen in FIG. 6.

The housing 17 containing the spring elements 18 and guiding the columns 16 are held at a distance above the table, as can be seen in FIGS. 1 and 2. On the one hand, they are each supported by two web-like walls 24 and 25 towering from the table 5 and, on the other hand, are connected via spacers 26 with a rail 7 of the sliding guide 6 in a holding connection. In addition, however, the two housings 17 are also connected to one another by a transverse yoke 27 , which can be seen in FIGS. 1 to 3.

In their rest position, the two looking around the joints 15 of the pillars 16 pivotable jaws 13 under the effect of their own weight to assume the position shown in FIG. 8, in which they assume an inclined position against the longitudinal axis 28-28 in which the friction linings 23 bear End faces are lifted from the outer circumference of the pile holder.

Each of the two jaws 13 cooperates with a cam disc 29 , which is non-rotatably seated on a shaft 30 which is mounted on the guide frame 3 below the table 5 but parallel to its plane. A hand crank 31 is used to drive shaft 30 , as can be seen in FIGS. 2 and 3.

The two cams 29 are arranged within slot-like cutouts 32 of the table 5 so that they can act laterally outside the rails 7 belonging to the slide guide 6 on the lower end faces of the jaws 13 . The cam disks 29 have approximately semicircular circumferential limits, and the shaft 30 carrying them is cut in one of the two transition areas between the circular arc-shaped circumferential section and the straight circumferential section. Upon rotation of the shaft 30 by means of the hand crank 31 , the cams 29 , when they have reached the angular position shown in FIG. 4, come into contact with the clamping jaws 13 . The cam disks 29 press the clamping jaws 13 from the inclined release position according to FIG. 8 into the active position according to FIG. 1. In the course of the further rotation of the shaft 30 , the clamping jaws 13 are then pressed against the force of the columns 16 by the cam disks 29 acting spring elements 18 raised from the position shown in FIG. 4 to the position shown in FIG. 5. The preload of the spring elements 18 between the columns 16 and the housings 17 or their actuating device 19 is increased considerably.

Due to the upward movement of the jaws 13 , the pile holder 9 clamped between them is taken along by a corresponding amount in the upward direction because the friction linings 23 of the jaws 13 generate a high holding force. As soon as the cam disks 29 pass through their top dead center, on the one hand the clamping jaws 13 , but on the other hand also the spring elements 18 are released, so that acceleration of the clamping jaws 13 in the downward direction occurs spontaneously. These remain in contact via their friction linings with the pile holder 9 , so that the restoring force of the spring elements 18 acts on the jaws 13 on the pile holder 9 and suddenly presses it downwards. He hits under the action of his own weight, which is additionally accelerated via the spring elements 18 , with his support surface 11 on the upper end 2 a of the pile 2 to be driven into the ground 33 and thereby rams it gradually deeper into the ground 33 . The pile holder 9 with its load weight 12 and the clamping jaws 13 with their guide columns 16 and the spring elements 18 acting thereon thus form a striking mechanism which can be made intermittently effective by rotating the shaft 30 by means of the crank handle 31 via the cam disks 29 .

It should be noted that the shaft 30 rotatable by the hand crank 31 with the non-rotatably mounted cam disks 29 on the table 5 must be arranged so that it passes tangentially around the circumference of the pile holder 9 inserted into the slot-like opening 8 .

Of course, it is not absolutely necessary to arrange the two cam disks 29 on a common shaft 30 . Rather, it is also within the scope of the possibility to mount each of the two cam disks 29 on its own, short shaft piece and then to couple these two shaft pieces by means of a suitable gear system for synchronism.

Since the device 1 described above for driving piles 2 is often used on slopes, in particular vineyards, it is important that the guide frame 3 for the pile holder 9 can be set relatively easily into the correct functional position. To make this possible, it is advantageous if the legs 4 of the guide frame 3 are both adjustable in terms of angle and adjustable in length. For this purpose, they each engage the table 5 via a joint 33 . They also each have at least two telescopically displaceable length sections that can be locked against each other in any relative displacement position.

Practical tests with the device 1 described above for driving piles 2 or the like into the ground have shown that piles of a relatively large length can be rammed safely and without problems with their help, provided that pile holders 9 are used which are suitable are to cooperate with the piles 2 as well as with the device 1 over the respectively required working area - that is to say the necessary driving depth. Important in the operation of the device 1 is also, that the cooperating with the stake holder 9 jaws open 13 automatically in its inoperative position according to FIG. 8, as soon as they pillars 16 in the respective housings to their lowermost end position according to FIG. 17 4 approach. It is then ensured that the pile holder 9, with the load weight 12 assigned to it, transfers its full weight and acceleration force to the pile 2 and thereby enables it to be driven into the ground quickly and quickly.

The design of the device 1 for driving piles 2 or the like into the ground, which is explained in detail with reference to FIGS . 1 to 8, can of course also be varied in various respects.

For example, it is easily possible not to firmly connect the two rails 7 of the sliding guide 6 to the table 5 of the guide frame 3 , but instead to fasten them to the outer circumference of the pile holder 9 . In this case, the rails 7 of the sliding guide 6 with the pile holder 9 can then be displaced vertically relative to the table 5 or to the guide frame 3 in the longitudinal grooves 21 of the clamping jaws 13 and, if necessary, also additionally insert into alignment grooves on the table 5 of the guide frame 3 fen, which have 13 longitudinal position with the longitudinal grooves 21 of the jaws.

As can be seen from Fig. 9, there is also the possibility of forming the pile holder itself directly through the spaced-parallel rails 7 of the sliding guide 6 , if these at their upper end by the support stop 11 and / or the load weight 12 in a fixed connection stand. In this case, too, the rails 7 are slidably received in the longitudinal grooves 21 of the clamping jaws 13 and can also engage in alignment grooves on the table 5 of the guide frame, which have a covering position with the longitudinal grooves 21 of the clamping jaws 13 . It may be advisable to equip the rails 7 with a trapezoidal cross section, to which the longitudinal grooves 21 of the jaws 13 are fitted.

Since here the profile or tube acting as a pile holder can be omitted, it is advisable to connect the rails 7 to one another by a plurality of spaced-apart guide bracket 35 , which can then serve as support systems for the pile 2 to be driven.

In Fig. 9 it can still be seen that there is also the possibility of using springs 18 not coil springs but rather leaf springs 18 ', 18 '', 18 ''', which are above the level of the table 5 provided on the guide frame 3 . They are rigidly clamped at one end, while their other end engages on a jaw 13 via the cantilever arm 14 and the joint 15 .

It can also be seen from Fig. 9 that each leaf spring 18 ', 18 '', 18 ''' is designed as a spring assembly consisting of several spring leaves, the spring leaves 18 '' and 18 '''not directly engaging the jaws 13 being relative to the spring leaf 18 'acting on these acting on the length adjustable and / or clamped. In a relatively simple manner, the spring force for the jaws 13 can be varied by changing the sliding position of the spring leaves 18 'and 18 '''.

While the device 1 for driving piles 2 according to FIG. 2 is provided with a hand crank, according to FIG. 9 there is also the possibility of coupling the shaft 30 for the cam disks 29 with the interposition of a reduction gear with a power drive 36 . This can be formed by an electric DC motor, which can be connected, for example via cables, to the power supply system of an agricultural utility vehicle (tractor).
