Definitions
- the invention relates to a pipe drawing machine for pulling a drill pipe for pile foundations after concreting, with a multi-section clamp, the links of which are articulated, and with hydraulic cylinders for moving the clamp members for the purpose of applying a closing force and with a base frame.
- a pipe drawing machine shows the utility model 77 18 042, in which all the clamp members form a closed, albeit expandable link chain, which determines the space requirement of the pipe drawing machine in the narrowest outer dimension.
- Pipe drawing machines can therefore not be used to pull drill pipes that run close to a wall.
- the base frame is fork-shaped and two clamping clamp members adjoining each other in the circumferential direction and covering the open fork of the base frame can be spread so far by means of a double-acting locking cylinder that the pipe-drawing machine is from the side opposite to that to be pulled pipe in the working position 5, and that the two clamp members can be locked together in the closed state.
- a pipe drawing machine according to the invention with two spread clamp members can be brought into a working position by pulling on a wall to pull a drill pipe located near the wall, the two spread clamp members during the lateral movement of the pipe puller up to Stop against the drill pipe can be pivoted in, if they would otherwise hit the wall when moving the pipe drawing machine towards the wall.
- the two expandable clamp members are locked together in a tensile manner. Due to this tension-proof locking, a multi-part clamp with a known function is created, which can be closed by at least one clamping cylinder in order to produce the tension between the pipe drawing machine and the drill pipe required for pulling the drill pipe.
- the expandable clamping clamp members perform an opposite pivoting movement around substantially immovable joint bolts and thus produce an opening which is at least as large as the diameter of the drilling roller to be drawn. Va.
- This simplest implementation of the invention when the pipe-drawing machine is brought into position simultaneously with the displacement of the pipe-drawing machine on the wall in order to continuously pivot the tensioning clamp members inwards, an embodiment is preferred in which the expandable tensioning clamp members are not pivoted outwards must be able to be brought to a distance from each other that allows the pipe drawing machine to be brought into the working position by pushing it towards the pulling drill pipe.
- the two adjoining tension clamp links are connected to intermediate links connected, which are mounted in mirror image on fixed vertical axes as well as two adjoining main tension clamp members, the two locking cylinders being connected to the intermediate members.
- the circular arc on which the ends of the wiper links move does not touch the wall, since the intermediate links in the one end position, in which the expandable tension clamp links adjoin one another, are only slightly inclined relative to the " normal to the wall.
- the vertical pivot axes of the intermediate links are expediently the diametrically arranged lifting cylinders of the pipe drawing machine, which are supported on the base frame and effect the step-by-step drawing strokes for drawing the drill pipe.
- the locking cylinders for moving the intermediate members and then for spreading apart the expandable clamp members are expediently fixed to the main clamp members.
- These main clamp members preferably extend over an arc angle of slightly less than
- the locked expandable clamp members form a counter support surface.
- the tensile lock between the two expandable clamp members can be designed as desired and can also be operated by hand. Preference is given to locking the expandable tension clamp members with a pivotally mounted on a tension clamp member about a vertical axis and with - 4 __.
- a thickened head-provided locking bolt wherein the other clamping member is Schell ns provided with a two-part abutment for the enlarged head of the Riegelbolze '.
- An abutment half is designed as an Ar ⁇ which can be swung outwards and is attacked by a double-acting small adjusting cylinder. As a result, the locking process can be carried out automatically, as is explained in more detail in the drawing description.
- Fig. 2 is a plan view
- Fig. 3 is a plan view like Fig. 2 with the open position 5 of the clamp assembly.
- the main components of the pipe drawing machine are a basic assembly, a clamp assembly 2 (Fig. 1) and two diametrically arranged lifting cylinders 4 and 5, the piston rods 4a and 5 of which are supported on the basic frame 1.
- the tension clamp arrangements are a basic assembly, a clamp assembly 2 (Fig. 1) and two diametrically arranged lifting cylinders 4 and 5, the piston rods 4a and 5 of which are supported on the basic frame 1.
- the base frame 1 to the wall 6th is fork-shaped open, which is not shown in the plan view of FIG. 2 for reasons of clarity. 1 shows the closed side of the base frame 1, which contains the entire hydraulic supply system.
- the tensioning clamp arrangement 2 initially comprises two main tensioning clamp members 2a and 2b, which extend over an almost 180 ° arc angle and are arranged on two approximately fork-shaped plate pairs 7 and 8.
- the fork shape of the plate pairs 7 and 8 corresponds approximately to the fork shape of the base frame 1.
- the plate pairs 7 and 8 are pivotally mounted on the diametrically arranged lifting cylinders 4, 5 and are actuated by a single double-acting, floating clamping cylinder 9.
- the clamping cylinder 9 is connected in an articulated manner to the pair of plates 7 at 11 pairs of tabs 10 and in an articulated manner to the pair of plates 8 at 12 via the piston rod 9a (FIG. 1).
- a clamping stroke was carried out by moving the piston rod 9a to the left and the tabs 10 to the right.
- the multi-section tension clamp arrangement 2 further comprises two adjoining tension clamp members 2c and 2d and two intermediate guards 2e and 2f in the region of the open fork of the base frame 1.
- the adjoining tension clamp members 2c and 2d can be expanded in order to open the link chain of the tension clamp assembly 2 to the wall 6 approximately as far as the fork-shaped opening of the base frame 1.
- the tension clamp member 2c are connected to the intermediate link 2e via a hinge pin 14 and the tension clamp member 2d via one
- the intermediate links 2e and 2f are also pivotally mounted on the lifting cylinders 4, 5 and connected to locking cylinders 16 and 17, which at 18 and 19 lie in a horizontal plane between the plate pairs 7 and 8 are set to oscillate.
- the outlines of the intermediate members 2e and 2f of the clamp arrangement are highlighted in FIG. 2 by a hatching for.
- the adjoining tension clamp members 2c and 2d are connected in an articulated manner to the intermediate members 2e and 2f, however their relative pivotability about the articulated pins 14 and 15 is limited by arcuate slots 20, 21 in the intermediate members, into the pins 22, 23 of the clamp members 2c, 2d engage.
- FIG. 2 shows the two adjoining tension clamp members 2c, 2d in the closed position, in which the piston rods of the locking cylinders 1.6, 17 are extended.
- the two clamp members 2c, 2d are locked by a locking bolt 24 which is pivotally mounted on the clamp member 2c about a vertical joint bolt 25 and has a thickened head 24a which, in the locking position, is behind a two-part abutment 26, 27 of the clamp member takes hold.
- the fixed abutment part 26 is a projection which is uniform with the tension clamp member 2d, whereas the abutment 27 is part of an arm 28 of the tension clamp member 2d which can be swung outward.
- This arm 28 is pivotally mounted about a hinge pin 29 of the tensioning shaft member 2d.
- a small double-acting actuating cylinder 30 fixed to the tensioning bracket member 2d is used to move the arm 28 with the abutment 27 between the locking position shown in FIG. 2 and a swung-out position.
- the arm 28 has a projecting corner 28a which, when the arm 28 is pivoted outward, presses against the head 24a of the locking bolt 24 and pivots it counterclockwise so that the thickened Head 24a is released from the fixed abutment 26.
- the tensioning clamp links 2c, 2d can slide past the wall 6 and pivot about the pivot pins 14, 15, but only as far as the length of the arcuate slots 20, 21 allow.
- the tensioning clamp members 2c, 2d can be pivoted inwards to the limit position in which the pins 22, 23 are located at the other ends of the slots 20, 21, as shown in FIG. 3, can also be done by hand.
- the pipe drawing machine is brought into the working position by being moved towards the wall 6 with the clamp clamp members 2c, 2d spread apart, so that the Drill pipe enters the fork-shaped opening of the base frame 1 and the open clamp assembly 2.
- the piston rods of the locking cylinders 16, 17 are then extended and the intermediate links 2e, 2f are pivoted inward in opposite directions.
- the tension clamp members 2c, 2d find a stop on the drill pipe and thus maintain their approximately aligned position with one another.
- This aligned position is important for an automatic threading of the locking bolt 24 into the abutment of the tension clamp member 2d, whereby it is ensured that the tension clamp member 2d reached the limit pivot position determined by the end position of the pin relative to the intermediate member 2f earlier than the other Tension clamp member 2c.
- the locking cylinder 16 is actuated throttled when extending its piston rod.
- the thickened head 24 arrives with its lower one Running surface in the area of the abutment 26 and 27, it slides against the pressure of a spring 31 over the abutment 26 and falls behind this abutment.
- the arm 28 can be pivoted during this process, so that when the thickened head engages behind the abutment 27, the arm 28 dodges against the sustained pressure in the actuating cylinder 30.
- the tension clamp members' 2c and 2d are thus locked together in a tensile manner
