Definitions

  • the invention relates to a linear guide for the falling body of a piling hammer, with at least one bearing housing at least partially enclosing the bearing housing.
  • Such Rammpatimmer be used in foundation work for the introduction of piles in the ground, especially the bottom of a body of water.
  • a falling body is raised periodically and dropped to produce ramming that drive the pile into the ground.
  • the case itself is guided in a linear guide of the hammer, in which he can perform linear up and down movements in the axial direction.
  • Known hammer hammers have linear guides made of metal and require lubricant, so that the case body is performed with the least possible friction and wear in its Verikalzi. When ramming underwater, the lubricants can enter the water, which is contaminated.
  • a ram hammer is known in which also a case body is linearly guided in a bearing housing, wherein between the case and the housing piston rings are arranged, which serve as sliding body.
  • the piston rings are not interchangeable without disassembly of the case from the bearing housing.
  • the object of the invention is to provide a linear guide of the type mentioned for the case of a piling hammer, which works without lubricant.
  • the at least one bearing housing is provided with sliding bodies which rest on the case body to guide this, and which are mounted and dismantled when installed case body.
  • a linear guide with sliding bodies can be operated without lubricant, but must take into account the fact that the sliding wear during prolonged operation, especially if the sliding body made of plastic. If now the sliding body made of plastic simply between the case body and a Bearing housings are arranged, an exchange of worn against new sliding body would be possible only with great effort. In particular, the case body would have to be removed from the bearing housing for this purpose. This is associated with considerable expenditure of time and represents an economic disadvantage, because the pile hammer is not available for ramming during the renewal of the sliding bodies.
  • the invention therefore provides that the sliding bodies can be mounted and dismounted when the falling body is installed. This results in a great economic advantage, since the replacement of the slider without removal and installation of the case can be done much faster than in the prior art.
  • the bearing housing has a plurality of distributed over its circumference, in each case from its outer side to its inner side facing the case body through continuous mounting openings, in each of which a slider is arranged and which are closable from the outside, each with a support member , To mount the sliders they are pushed through the mounting holes until they rest against the drop body. Then, the mounting hole is closed by the support member which supports the slider from the outside and presses it to the case body. During operation of the piling hammer, the lateral forces required to guide the falling body are transmitted via the sliding bodies to the supporting elements and thus to the bearing housing.
  • the peripheral surfaces of the sliding body and the mounting holes are formed at least partially cylindrical, with a designed as a sliding surface end face of the slider is adapted to the peripheral surface shape of the case.
  • the case body is cylindrical shaped, so has a cylindrical peripheral surface.
  • the front side of the sliding body then has a complementary shaped sliding surface, which rests in the installed state of the slider on the cylindrical peripheral surface of the case body over a large area. The falling body can thus move freely in the vertical direction, whereby it is always guided by the entire sliding surface of the slider.
  • the invention is also applicable if the falling body has other shapes, for example an oval or square cross-section.
  • the sliding surfaces of the slider just received a different curvature, which is adapted to the case body.
  • the sliding surfaces of the sliding body can be configured as flat surfaces.
  • the design of the peripheral surfaces of the slider is advantageously determined by those of the mounting holes. Since the mounting holes can be performed in a particularly simple manner as holes, there is a particular advantage for the cylindrical shape of the mounting holes and the peripheral surfaces of the slider.
  • the invention is further improved by the support elements having a central projection and the sliding bodies are provided with a central opening, so that they can be plugged onto the projection of the support elements. In this way, the position of the slider is fixed relative to the support elements, so that installation of the sliding body in a tilted manner or in the wrong position is avoided.
  • the sliding body or the supporting elements are provided with a transversely to the direction of movement of the falling body elastically formed compensation element.
  • the sliding bodies can be fastened to the support elements on their side facing the support element, on the one hand the installation is facilitated since a fixed sliding body can not accidentally fall down, on the other hand the position of the sliding bodies is fixed with respect to the support elements, in particular with respect to a rotation about one transverse to the direction of movement of the case body arranged axis. It is therefore necessary to pay attention to the correct position of the support elements when installing the unit consisting of slider and support element. The sliding bodies are then automatically in their correct installation position.
  • the sliding bodies are provided with screw threads on their side facing the support element and / or the support elements have bores for the passage of fastening screws, wherein at least one sealing element for preventing the penetration of water is preferably provided between at least one sliding body and the associated support element ,
  • the sliding body can be screwed to the support elements in their correct mounting position.
  • the sealing element which may be configured for example as an O-ring, the penetration of water into the linear guide according to the invention.
  • the leakage of, for example, lubricant from the interior of the linear guide is prevented in the water.
  • the sliding bodies are provided on its side facing the support member with cylindrical projections and the support elements have bores for receiving the cylindrical projections, wherein the cylindrical projections have threads for screwing in fastening screws.
  • the measure that the support elements radially outside of the sliding body arranged holes for the passage of mounting screws, which are screwed into associated threads on the bearing housing, serves to fix the support elements with respect to the bearing housing, in particular the fixation in the direction of rotation according to the latter two embodiments and so that finally to fix the correct mounting position of the slider with respect to the bearing housing and the case body.
  • a second embodiment of the invention provides that the bearing housing has at least one externally accessible, preferably closable, mounting opening, through which a band-shaped sliding tangentially to the case body is inserted, preferably the bearing housing on its inside with a the circumference of the case following Nut is provided for receiving the band-shaped slider.
  • the band-shaped sliding body is guided through the groove, so that, for example, a worn sliding body can be pulled out through the mounting opening and a new sliding body can be pushed tangentially into the groove into the groove.
  • the groove prevents a displacement of the band-shaped slider in the direction of movement of the case.
  • the band-shaped sliding body consists of interconnected sliding elements.
  • the sliding elements themselves are rigid enough to withstand the high forces required to guide the falling body, while ensuring the necessary for the introduction of the band-shaped slider through the mounting opening mobility by the concatenation of the sliding elements to the band-shaped slider.
  • the sliding elements have on one side characteristics and on the opposite side indentations, which are intended to accommodate the characteristics of an adjacent sliding element, so that a concatenation is made possible by positive locking.
  • the sliding elements are made of polymer material and are produced by injection molding. If necessary, however, two or more types of sliding elements composed of two or more different materials can be combined to improve the function of the slider. This then consists of periodically successively arranged sections, which are each formed from two or more different types of sliding elements.
  • the bearing housing on two opposite mounting openings through which a band-shaped slider is inserted.
  • Each band-shaped sliding body thus encloses almost half of the circumference of the case.
  • the cost of two band-shaped slider is relatively low. Less would be the effort only with the arrangement of a single band-shaped slider. This would then but the case body over a Surround peripheral area of more than 280 ° in order to achieve similar good results in the leadership of the case. Such a sliding body would therefore be very long and in particular difficult to insert during installation.
  • the mounting holes are each closed by a lid, which is preferably fastened by means of screws on the bearing housing, slipping out of the band-shaped slider and the ingress of dirt is prevented in the interior.
  • FIG. 1 recognizes a case body 1, which is guided in the vertical direction 2 within a guide tube 3 movable.
