Definitions

  • the invention relates to a device for inserting and / or extracting building profiles in the form of duct boards, sheet piling elements or the like, into or out of the ground, with a vibratory system designed as a vibrating hammer, consisting of an exciter mounted in a housing via spring elements, which means a clamping device with the building profile to be moved can be connected in terms of vibration and the clamping device is mechanically connected to two spaced-apart striking surfaces, and the housing is slidably fastened to the striking surfaces, the distance between the striking surfaces of the exciter and the striking surfaces being limited by adjustable stops (see for Example FR-A-1479724).
  • Vibrators or rams are used to drive in sheet piling, channel boards or generally ram profiles, which are slidably arranged on a guide frame or leader.
  • the ramming or building profile to be driven is detected by a clamping device and fixed below the vibrator.
  • a clamping device can be seen, for example, from DE-A-33 38 144.
  • Clamping devices are also known which have a continuous profile insertion, so that the building profile is lifted into the profile insertion with the aid of a lifting device and passed through until it reaches the required height to the ground in order to be driven. During the work process, the clamping device progressively advances to the upper end of the construction profile when the construction profile is introduced into the ground.
  • Vibration systems are also known which can also be used as a hammer, in which the tensioning device is opened and strikes the upper end of the construction profile.
  • the steel profiles can be introduced into the ground, but not driven out of the ground. But this is precisely why often greater forces are required because the adhesion between the building profile and the soil increases over the course of time in which a building profile is in the ground due to corrosion, rust, soil compaction and the like.
  • the known systems require additional aids, such as heavy pure impact systems, large freeriders, special lifting devices and the like.
  • additional aids such as heavy pure impact systems, large freeriders, special lifting devices and the like.
  • the additional transport to and from the site, and the working hours there are other disadvantages.
  • the use of such devices is often difficult or impossible due to the local conditions, especially in buildings in the city. Furthermore, the use of such devices is associated with a large and disruptive noise.
  • a hammer works with greater efficiency than a vibrator, since the paths of the structural profile to be driven in per stroke are greater than with a vibrator and a relatively high amount of energy has to be applied with every transition from static friction to sliding friction.
  • the invention is based on this finding.
  • the invention is therefore based on the object to provide in a device of the type mentioned in addition to the imprinted vibration energy means with which a variable and the independently and without unfavorable influence on the vibration system or the vibration systems If necessary, adaptable force can be continuously exerted on the construction profile to be inserted or extracted, so that the efficiency of the device can be increased considerably while saving energy.
  • the invention is also based on the object of specifying means to generate impact forces in the pulling direction of a building profile with the aid of a vibrating hammer, so that building profiles located in the ground and firmly adhering can be extracted by impact forces in combination with static forces.
  • This measure according to the invention succeeds in impressing both a changeable static force and a dynamic force generated by the vibration system or the hammer independently of one another on the construction profile to be inserted or extracted.
  • the spring travel of the exciter's springs can also be designed cheaply for any application.
  • the vibration ability of the springs is influenced, but the possibility of adjusting the spring travel allows a maximum solution to be achieved in relation to the additional forces achieved.
  • the striking surfaces are advantageously designed as striking plates which are spaced apart from one another by rods.
  • This measure according to the invention enables the different forces, namely the dynamic forces from the exciter and the static forces from a fluid, for example hydraulic, system to be impressed independently of one another on the structural profile via the clamping device.
  • the exciter has impact-damping elements at the ends opposite the striking surfaces or striking plates, so that both the vibrations generated and transmitted by a vibrating hammer and the strikes caused by a corresponding switchover are acoustically damped, the vibration losses occurring being extremely low.
  • shock-absorbing elements advantageously each consist of a wooden plate or of materials with similar damping properties.
  • the static forces acting on the housing are brought about with the aid of a leader.
  • the energies required for this are extremely low.
  • the adjustable stops to limit the spring travel of the springs which are effective between the shock-absorbing elements and the housing or the supporting structure, each consist of a screw bolt which is provided with locking nuts.
  • the stop distance and thus the spring travel can thus be changed in a simple manner, both for forces in the direction of insertion and in the direction of pull.
  • the housing is slidably connected to the linkage with the aid of at least one sliding guide which has bearing bushes. This results in a safe movement of the oscillatory system without jamming or the like.
  • the amplitudes of the oscillatory system are also adjustable so that the system can meet all requirements that occur in practice.
  • the ratio of the applied static force to the ratio of the applied dynamic force can be changed in this way.
  • the static forces acting on the housing or the supporting structure can, according to the invention, be kept constant within a definable fluctuation range after initiation of a movement process of the construction profile, so that the process described above can be achieved.
  • the exciter 1 is located in a housing 2, in which it is resiliently supported by spring elements, not shown, such that it can carry out vibrations in the vertical direction.
  • the housing 2 has a column or sliding guide 12 which is slidably mounted along a plurality of guide columns. Four such guide columns 11 are expediently provided.
  • the guide columns 11 are screwed at their ends with striking plates 7 and 8.
  • a hydraulic device with an extendable and retractable hydraulic cylinder 15 is located above the upper impact plate 7.
  • the lower striking plate 8 is integrated, for example welded, with the clamping device 3 designed as a collet.
  • the clamping device 3 designed as a collet.
  • a construction profile 4 is shown in the clamped state.
  • the exciter 1 has an upper and a lower damping plate 9 or 10 made of wood.
  • Adjustable stops 13 and 14 are connected to the housing 2.
  • the lower stop 13 defines the oscillation amplitude of the lower damping plate and the upper stop 14 the amplitude of the upper damping plate 9.
  • Reference number 16 indicates a leader guide and 5 denotes the pulling direction upwards and 6 correspondingly downwards.
  • a steel profile 4 is to be driven into the earth by vibration and impact, it is gripped by the tensioning device 3 and clamped by means of a hydraulic device (not shown in more detail).
  • a static force is exerted on the housing 2 in the pulling direction 6, as a result of which the adjustable stop 13 is guided up to the striking plate 8.
  • the static force applied is transmitted to the steel profile via the striking plate 8 and clamping device 3 and drives it into the ground.
  • the hydraulic cylinder 15 is now extended, the exciter 1 is clamped between the upper and lower striking plates 7 and 8 by its piston rod, so that when the exciter 1 is switched on, its vibrational energy via the lower striking plate 8 and the clamping device 3 is applied to the structure under static pressure. or steel profile 4 is transmitted so that the forces are superimposed.
  • the device according to the invention can also be used in all the functions described, namely vibrating, hitting and the action of a static force, in order to exert a corresponding tensile force on a construction profile.
  • a static force is exerted in the pulling direction 5, which acts via the housing 2 and presses its stop 14 against the striking plate 7. These forces are transmitted to the construction profile 4 via the guide columns 11 and the clamping device 3. If the exciter is switched on in this state, it can swing freely downwards and strikes with its upper damping plate 9 against the upper striking plate 7 during its upward movement and thus acts as a hammer, the stroke of which is transmitted to the construction profile 4.
  • the static force is retained or is immediately adjusted with each upward movement of the construction profile and regulated to the predetermined size.
  • the device can work as a vibrator, and the static force can also be maintained here.
  • the device can be used as a hammer or vibrator with constant jamming and thus guiding the construction profile in the pulling or pushing direction while maintaining a static force, depending on how the ground conditions require it.
  • the adjustable stops enable the system to be optimized, and the damping plates ensure a corresponding reduction in wear and noise.
