    DETAILED DESCRIPTION OF THE INVENTION Figure 1 shows a working machine 1. The working machine 1 can be, for example, an all-in-one machine or another working machine with a boom 2, the end of which can be mounted with a percussion hammer 3. At the upper end of the percussion hammer 3 such as a quick-release fastener to be attached to the end of the boom 2, of which the impact hammer 3 is attached to the boom 2. However, preferably the lower end of the impact hammer 3 is, for example, a bolt-on fastener 3b, such as a quick-release fastener attached to the end of the boom 2.
    N 30 In the lower part of the hammer 3 there is a bracket illustrated by 3b in Fig. 1, the boom 2 does not need to be raised as much as when the impact hammer 3 is used if the boom is attached to the bracket 3a at the upper end of the hammer 3.
    Thus, N is able to work in a work area where the working height is limited.
    The impact hammer 3 strikes the upper end of the pile 5 so that the pile 5 can be mounted on the ground.
    Between the impact hammer 3 and the upper end of the pile 5 there is an accessory 4 which allows the upper end of the pile 5 to be struck by the impact hammer efficiently and without damaging the upper surface of the pile, even if the impact hammer 3 is somewhat oblique to the pile 5.
    With such a solution, it is possible to install the pile 5 also in a very cramped space.
    The pile 5 can be installed, for example, inside a building so that the frame of the working machine 1 is outside the building and only the impact hammer 3 and the hammer 3 end of the boom 2 are inside the building.
    Figure 2 shows an accessory 4. The accessory 4 comprises an impact part 6 and a transmission part 7. The impact part 6 has an arm part 8 and an impact part 9. The arm part 8 has a device which allows the impact part 6 to be attached to the impact hammer 3. This can be formed by recesses 10 in the arm part 8, for example. by means of which the wedge members 11 of the percussion hinge 3 fasten the percussion part 6 to the percussion hammer 3. These wedge members 11 are corresponding to, for example, the blade can be fastened to the percussion hinge 3 if desired.
    The pile part 13 is arranged in connection with the upper part of the pile 5 to be installed on the ground.
    The transmission part 7 further has a transmission surface 14 which is placed against the upper surface of the pile 5 to be installed on the ground.
    In the embodiment of Figure 2, the pile 5 is a pipe pile and the pile part 13 of the intermediate part 7 is cylindrical.
    Thus, the pile part 13 is arranged inside the upper part of the pile 5.
    The outer diameter of the cylindrical pile part 13 can be selected to correspond to or be only slightly smaller than the inner diameter of the pipe pile 5.
    In this way, the transmission part 7 rests well on the upper part of the pile 5.
    The transfer surface 14, on the other hand, is formed on the lower surface of the receiving part 12, and the transfer surface 14 rests against the upper surface N of the pile 5. 5 The impact part 9 has a part 15 of the ball surface and the receiving part 12 has a part a spherical surface 16. A portion of the spherical surface 16 of the receiving portion 12 corresponds to a spinning portion 15 of the striking portion 9 so that the striking portion 9 can be fitted in connection with the receiving portion 12E.
    There is thus a contact surface between the impact part 9 and the receiving part 12.
    N In the embodiment of Fig. 2, a portion of the receiving portion 12 of the spherical surface 16 and a portion of the spherical surface 15 of the impact portion 9 are each hemispherical.
    N In Fig. 2, the impact part 6 and the transmission part 7 are arranged coaxially.
    Fig. 35 — Fig. 3 shows a situation in which the parts of the apparatus are identical to those shown in Fig. 2, but the impact hammer 3 is not exactly vertical above the pile 5.
    but the impact of the hammer 3 comes at an angle. The direction of the axis 17 of the impact part 6 thus differs from the direction of the axis 18 of the transmission part 7. In this case too, the transfer surface 14 is against the upper surface of the pile 5 and there is still a contact surface between the impact part 9 and the receiving part 12. In this way, the impact is transmitted to the pile 5 efficiently and there is no special damage or injury to the upper surface of the pile 5.
    In the embodiment of Fig. 4, the pile part 13 of the intermediate part 7 is formed to fit outside the upper part of the pile 5. Such a solution is useful when fitting the intermediate part 7 in connection with, for example, a concrete pile, a square pipe pile, an H-beam, an I-beam or a pile pile or the like at the top of a pile. The design of the pile part 13 is adapted to correspond to the upper end of each pile 5 in question. In this solution, the intermediate surface 14 is connected to the pile part 13.
    The spherical surface portion 16 of the receiving portion 12 and the spherical surface portion 15 of the impact portion 9 may each be non-hemispherical in shape. In the embodiment of Figure 5, part of the spherical surface 16 of the receiving part 12 is in the shape of a caliper smaller than a hemisphere. In the embodiment of Figure 6, part of the spherical surface 16 of the receiving part 12 is zone-shaped. In this case, the receiving part 12 can be in the form of, for example, a hemisphere, from the upper part of which a slate smaller than a hemisphere has been removed.
    Fig. 7 shows a transmission part 7 with a first transmission surface 14 on the lower surface of the receiving part 12 and a second transmission surface 14 in connection with the pile part 13. Such a transfer part 7 can be used, for example, in connection with a larger pipe pile, so that the first transfer surface 14 is placed against the upper surface of the pile 5, whereby the pile part 13 rests entirely inside the pipe pile. In the case of a smaller pipe pile, the second intermediate surface 14 is placed against the upper surface of the pile 5, whereby only the lower end of the pile part 13 is located inside the pipe pile o.
    AN Fig. 8 shows an embodiment in which the part 5 of the receiving part 12 has a spherical surface 16 larger than a hemisphere. The impact part 9 has a retaining member 20, which is adapted to hold the receiving part 12 in connection with the impact part 9. Thus, S 30 causes the transmission part 7 to remain in connection with the impact part 6 when the impact part 6 is lifted.
    E The transmission part 7 has a gripping pawl 19 in the pile part 13, which can be, for example, a hydraulic press with which it can grip the pile 5. Thus, by lifting the transfer part 7, the pile 5 can also be lifted when the impact part 6 is attached to the impact bar. 3, i.e. via the impact part 6, the transmission part 7. In other words, with the impact hammer 3, the pile 5 can be lifted by means of the accessory 4. The pile 5 shown in connection with Fig. 8 is a tongue.
    Instead of the pile part 13, a plate or plate or other similar flat part can be arranged as the guide part of the intermediate part 7. In this case, the accessory 4 can be used with the impact hammer 3, for example for compacting and / or leveling the soil. In the embodiment of Fig. 9, a winch 21 is fastened to the percussion hammer 3. The winch 21 is connected to a wire 22 which can be fastened to the pile 5 by fastening means 23. The winch 21 can be tightened so that the pile 5 remains with the percussion hammer 3. Thus, the impact hammer 3 is used to raise the pile 5 by means of the winch 21 and the wire 22. At the same time, the transmission part 7 remains with the impact part 6 when lifting the impact part 6, even if the impact part 6 and the transmission part 7 are not connected to each other by the solution or other solution shown in Fig. 8. , with which the impact part 6 and the transmission part 7 are made to remain together with each other when the impact part 6 is lifted. In the embodiments shown in Figs. 2 to 8, the impact portion 9 of the impact portion 6 is concave and the receiving portion 12 of the transmission portion 7 is convex. In such a solution, the impact part 9 of the impact part 6 can also be called the cup part and the receiving part 12 of the transmission part 7 can be called the cup part. However, the accessory 4 can also be formed in such a way that the impact part 9 of the impact part 6 is convex and the receiving part 12 of the transmission part 7 is concave. It will be apparent to one skilled in the art that as technology advances, the basic idea of the invention can be implemented in many different ways. The invention and its embodiments are thus not limited to the examples described above, but may vary within the scope of the claims. o OF O
