Definitions
- the invention relates to a leader with a sliding connection for guiding a moving weight, especially a battering ram and / or the leadership of a a lifting arm, preferably connected via a rotating swivel unit Guide unit with a leader, especially in a ramming device of masts, pilots, foundations or the like, the leader being rectangular or has a square cross-section, and four at right angles to each other arranged plates or the like., The edges of four, circular Cross-section supporting support columns are formed.
- the object of the invention is therefore to provide a sliding connection of the type cited at the beginning create, which on the one hand avoids the disadvantages of the known guide bearings, and the on the other hand, the immense forces of the moments, especially the transverse moments, at any position of the leader in the room.
- the object is achieved by the invention.
- This is characterized in that at least two opposite panels of the leader in parallel from the corner column axes arranged inward against the center line of the leader are that two nested coaxial hollow cylinders are provided, wherein the outer hollow cylinder is connected to the weight or the guide unit and the inner hollow cylinder the support guide column more than 180 °, in particular 260 °, encloses, and the end faces of the inner hollow cylinder as an outer flange for the outer hollow cylinder are formed, and that as a guide bearing on the Supporting guide column and hollow cylinder arranged one inside the other in cross section Have circular sector-like recess, the chord of this recess on Inner diameter of the inner hollow cylinder is smaller than the diameter of the support guide column and the two the cut surfaces of the circular sector-like recess form a right angle, and the crossing point this leg on the side having the sector-like recess, outside the center of the guide camp.
- the invention it is possible for the first time to create a sliding connection which any position of the leader in the room can withstand all transverse forces. So can for example the leader with the battering ram 90 ° from the vertical be pivoted and quasi shouldered for transport without any Risks are taken. Leverage moments occur on the several Can be a thousand kpm. The invention ensures that the train and Pressure forces are mastered perfectly.
- the inner hollow cylinder a relatively soft material, preferably a bearing material, in particular made of bronze, and the outer hollow cylinder made of a relatively hard material, in particular made of steel.
- the inner Rotation surface of the inner hollow cylinder formed as a sliding surface. Naturally such a measure reduces the friction losses.
- the length of the tendon is the Recess on the inner diameter of the outer hollow cylinder larger than that Distance between the legs and those parallel to the legs Tangents on the outer circumference of the inner hollow cylinder.
- forms the sliding connection on the support guide pillar is a captive unit. So are however, the two hollow cylinders, when they are removed from the supporting guide column, very easy to separate. You can namely turn or turn against each other be twisted together.
- FIG. 2 a shows a ramming device
- FIG. 2 b a section A-A of Fig. 2 a
- Fig. 2 c the sliding connection with the support guide column
- Fig. 3 is a plan view of the sliding connection with the support guide column.
- a leader 20 is vertical in the working position. It is lifted by an arm 22 held, the free end of a rotary swivel unit 27 of the leader 20th connected is.
- the sliding connections or guide bearings 1 are on a support guide column 29, which is part of the leader 20, pushed on. Using holding arms 28, the guide bearings 1 are rigidly connected to a pile driver 21.
- a Foundation device 24 to be driven is vertical under the ram bear 21 set up on the ground 25 and a Schiaghaube 23 of the ramming 21 on the top free end of the foundation 24 placed.
- the guide unit 26 is by means of this guide bearing 1 with a support guide column 29 of leader 20 connected.
- the inner diameter (di) of the outer hollow cylinder 16 and the outer diameter (da) of the inner hollow cylinder 2 is slight Game; the inner surface of rotation 5 of the inner hollow cylinder 2 is as Slide surface formed.
- the inner rotating surface 5 of the inner hollow cylinder 2 includes the support guide column 29 with play.
- the length of the chord 6 on the inside diameter (di) of the inner hollow cylinder 2 is less than the diameter of the Support guide pillar.
- the end faces of the inner hollow cylinder 2 are as outer flanges 7 and are located on the end faces 8 of the outer hollow cylinder 16 with game on.
- the guide bearing 1 points, uniformly parallel to its longitudinal central axis 17, in its basic form a circular sector-like recess 10.
- the two close the cut surfaces of the circular sector-like recess 10 forming legs 11, 12 an angle of 90 °.
- the crossing point of this Legs 11, 12 lie on the side having the sector-like recess 10, outside the center of the guide bearing 1.
- the wall thickness of the outer Hollow cylinder 16 must be less than the length of the chord 6 on the inner diameter (di) of the inner hollow cylinder 2 to allow intermeshing.
- the support guide column 29 is part of leader 20, with at least two parallel opposing plates 30 parallel from the corner column axes inwards against the Middle of leader 20 are arranged shifted.
- the other two plates 31 can be welded to the center of the support guide column 29.
- the battering bear 21 is arranged via holding arms 28 which are arranged on the outer hollow cylinder are connected to the leader 20.
- the inner hollow cylinder 2 should therefore encompass the support guide column 29 with preferably 260 °.
- the chord 13 on the inner diameter of the outer steel cylinder 16 must be larger than the distances a, b. These distances result from the legs 11, 12 and the associated parallel tangents on the outer circumference of the inner hollow cylinder 2.

Description
Darüber hinaus muß zur einfachen Trennung der beiden Hohlzylinder im von der Trag-Führungssaule 29 abgezogenen Zustand, die Sehne 13 am Innendurchmesser des äußeren Stahlzylinders 16 größer sein als die Abstände a, b. Diese Abstände ergeben sich aus den Schenkeln 11, 12 und den dazugehörigen parallelen Tangenten am Außenumfang des inneren Hohlzylinders 2.
