  • Such a pile driver essentially consists of a piston rod with a piston, over which the hollow cylindrical Ram is led.
  • the ram is provided with a cover at the top a valve device is equipped. This is used to ram in a pole Piling device with one attached to the lower end of the piston rod Device placed on the rod.
  • the ram is fed by Compressed air raised in the space between the piston and cover, the valve device is opened, the ram falls on an anvil, which also is attached to the lower end of the piston rod, the rod is driven in.
  • this piling device on the pole that ram into the ground is put on, and its weight is considerable, it is necessary that an additional lifting device is carried along with the piling equipment must, which consists for example of a tripod with a cable. Thus, this device has the same disadvantage as the above Piling device on.
  • the poles used to ram into the ground have one certain length on. These can be extended with additional poles become. In the above example, it is therefore necessary for each The piling device is lifted from the last bar must be so that the rod can be extended by another rod can. Then the pile driver has to be put back on the newly inserted pole be put on. This involves a relatively large amount of work, it is practically not possible to use a ramming probe Have the device carried out by a single person.
  • the object of the present invention is now a To create piling equipment that is simple in construction and handling and with no guide frame or additional supports supported on the floor a hoist can be used. Furthermore, this piling device can be put into operation and operated by one person.
  • the anvil is advantageously made of an annular body formed, which can be fastened to the rod by means of wedges, which enables the The anvil can be adjusted in height with little effort, using the attachment is optimal.
  • An advantageous embodiment of the invention is that a Part of a lifting device, which is preferably designed as a cable, on the rod can be attached.
  • a Part of a lifting device which is preferably designed as a cable, on the rod can be attached.
  • this attachable part and on the other hand attached to the ram.
  • the ram can be easily lifted along the bar, so that the height of the anvil can be adjusted.
  • the upper end region of the ram is advantageously included provide an end cover so that between the piston and end cover a room is formed in which the compressed air can be supplied, to raise the ram.
  • a valve device on this end cover attached which is designed so that it automatically controls the at least one drain opening in the end cover for the correct one Time opens and closes. This can control the pile driver be designed cost-effectively and reliably.
  • FIG. 1 is to be rammed into the ground 1
  • Rod 2 an anvil 3 put over.
  • This anvil 3 consists of one annular body 4, the wedges 5 on the rod 2 on a selectable Height is fixed.
  • the pile driver 6 is mounted on the anvil 3.
  • This comprises a piston rod 7, which is hollow-cylindrical is and through the longitudinal opening 8, the rod 2 is guided.
  • the piston rod 7 is equipped with a piston 9.
  • the ram 10 is provided with a cylindrical bore 11, which cooperates with the piston 9.
  • At the top end portion 12 of the Ram 10 is attached to an end cover 13, while the bottom End region 14 of the ram 10 is equipped with a guide cover 15.
  • the end cover 13 and the guide cover 15 form the guides for Moving the ram 10 along the piston rod 7.
  • a valve device 16 is arranged in the end cover 13, while an inlet opening 17 for compressed air is provided in the ram 10, which opens into the space 18 between the piston 9 and the end cover 13. Furthermore, there is a ventilation opening in the lower end region 14 of the ram 10 19 attached. The operation of this valve device 16 the inlet opening 17 and the vent opening 19 will be precise later described.
  • an attachable Part 20 of a lifting device 21 are placed on the rod 2 to be rammed into the ground 1.
  • This part 20 points Deflection pulleys 22, over which a rope 23 is guided.
  • a holding device 24 for fastening the rope end and a further deflection roller 25 is attached.
  • the pile driver 6 is raised from the state supported on the anvil 3, as shown in Fig. 2. This releases the anvil 3, he can after the rod 2 rammed into the ground by a certain amount has been, and before he comes to the plant on floor 1, further be moved up.
  • Fig. 3 shows the pile driver 6, which corresponds to Fig. 1 on the Piston rod 7 is supported on the anvil 3.
  • the ram 10 is in the lower position, which is taken when, for example, a blow to the anvil 3 is done.
  • an elastic means in Formed a spiral spring 26 by means of which an annular disc 27th is pressed against the end cover 13.
  • Drain openings 28 attached in the illustrated position of the ram 10 are closed by the annular disc 27, for which this with a Sealing washer 29 is provided.
  • the annular disc 27 is through made of bolts 30 guide means guided such that they differ from End cover 13 can move away against the piston 9 to the To be able to release drain openings 28.
  • the annular disc 27 in the direction of the piston 9 are the guide bolts 30 equipped with a stop 31. Between the annular Disc 27 and the end cover 13 are further second elastic Means in the form of compression springs 32 attached over the guide bolts 30 are turned over.
  • the force of the coil spring 26 is greater than that Sum of the forces of the compression springs 32, so that in the one shown in FIG. 3 Position of the ram 10, the drain openings 28 are closed.
  • the coil spring 26 gives the annular Disc 27 free. Due to the overpressure that prevails in room 18, the annular disc 27 in the sealing position shown in Fig. 3.
  • the Compression springs 32 are dimensioned accordingly.
  • the ramp 10 is run up until one in the Ram 10 attached vent 35 has passed over the piston 9, whereby the room 18 is connected to the environment. Once that position is reached, there is a pressure drop in space 18, the compression springs 32 cause the annular disc 27 to move away from the end cover 13 and are pressed against the stops 31, the drain openings 28 in End cover 13 are opened, the ram 10 falls down and strikes anvil 3. Due to this impact effect, which the anvil 3 is transferred to the rod 2, the rod 2 by a certain amount in rammed the floor.
  • the ram 10 is thus again in that shown in Fig. 3 Position, the cycle can start again.
  • the feeding of the Compressed air through the inlet opening 33 can take place continuously, so that for this purpose no additional control is required.
  • FIG. 5 shows that at this embodiment in the end cover 13 six over the circumference distributed outlet openings 28 are provided. Furthermore are three guide bolts 30 attached to guide the annular disc 27. Of course, other arrangements could also be used. Of furthermore, a ram 10 is used in this embodiment, which consists of a thick-walled hollow cylinder is formed. Here, too, would be other forms possible, it would also be conceivable for additional weights to be attached to the ram could become.
  • An embodiment of such an inventive Piling equipment can, for example, have a total weight of around 35 kilograms exhibit.
  • the fall height of the ram is about 20 cm.
  • This Piling equipment is very easy to use, which is easily done one person can be carried out.
  • For commissioning can be in the Piling device and the anvil inserted a rod to be rammed into the ground the anvil is attached to the rod, the rod is inserted into the vertical position, the ramming process can begin.
  • the pile driver by the very simple lifting device can be lifted off the anvil.
  • To extend a rod by another becomes only the one that can be placed on the rod Part 20 removed from the already partially rammed rod and placed on the extension rod inserted in it.
