Definitions
- the invention relates to a device for manufacturing and expanding boreholes and destroying them and replacing underground pipelines or for driving pipes.
- a drilling device for the destructive replacement of an in For example, underground pipeline is out U.S. Patent 4,507,019.
- This device consists of a frame with an adjustable Bearing piece for two feed cylinders connected by a slide.
- a rotary drive is arranged on the slide, its horizontal shaft with an external thread is provided and with the internal thread on rear end of a multi-shot Screw drill pipe screwed.
- the frame requires the known device a large construction or launch pit.
- German patent application 41 13 422 suggests Mount head with a clamping device and one Clamping and turning device in front.
- the clamping device has two clamping jaws that grip the pipe and that of hydraulic cylinders be driven to the pipe between clamp and secure against twisting.
- the clamping and rotating device has one around the tube axis rotatable support on which two of opposite Clamping jaws acting on the side of the pipe are arranged, each of a cylinder are driven. Another cylinder drives you Holders in such a way that these around the axis of the tube is turned around.
- German patent specification 41 22 350 known drilling device which is arranged above ground in terms of its space requirements and is initially inclined downwards Auxiliary drilling creates to reach the laying depth and then continue drilling in the horizontal direction.
- To the Laying house connections are such devices not suitable because they are large because of their external dimensions do not accommodate in the sidewalk area to let.
- the invention lies on the basis of this prior art underlying the problem of creating a device the space requirement is small and the fast connection a rod section with the rotary drive on the one hand and the back end of one already in the ground located linkage allowed on the other hand.
- the invention proposes Device of the type mentioned above, the rotary drive according to the invention with a plug coupling a lining on the one hand and a locking piece on Is provided at the end of a boom or boom section, that is on without the need for screwing can be easily introduced into the feed. This can for example through a radial opening of the feed happen.
- the chuck avoids screwing on the drive side and can point in the direction of the axis of rotation, in the direction of advance have an open bowl in which the Insert the rear end of the new boom section axially leaves. This bowl then prevents the boom shot while rotating through the insertion opening falls out of the feed. Is the boom shot or seal the bowl, then it is possible, the linkage via a feed line ending in the bowl bottom to provide with a liquid.
- the plug coupling can be made like a bayonet lock be formed and for example a forehead collar own behind which there is at least one radial Stop located when turning the drive shaft of the feed connected to the rotary drive in both Directions for screwing the front end of the new one Device shot with the back end of one already Linkage in the ground as a driver acts.
- This driver preferably acts with one Stopping area of the boom section together.
- the feed and the rotary drive with the plug-in coupling are preferably in a frame with a rod guide arranged in the at least one jacking cylinder can be arranged to the rotary drive with the plug-in coupling to move about the length of a boom shot. This can also be done with the help of a preferably arranged in the middle between the two jacking cylinders third propulsion cylinder happen Piston rod is then connected to the rotary drive. On this results in a short overall length with a long one Driving force and relatively large length of the boom section. Telescopic cylinders are also suitable for propulsion.
- a disadvantage of such cylinders is that Forces are different at each level and therefore not continuous pushing and pulling forces and also not deliver continuous feed speed.
- the Power transmission from cylinder to rotary actuator too over a chain deflected like a pulley take place, whereby the feed path for example can double.
- a cylinder block can also be used are used, the one with three piston rods is provided, one in one and the two extend others in the opposite direction.
- the holding claw is preferably articulated with one End of a two-armed lever with a frame-fixed Pivot point, which enables a linear claw movement, if the pivot is an elongated hole, for example of the claw carrier reaches through.
- the frame can be extended with horizontally extendable supports be provided, via which the recoil forces be introduced into the ground.
- the boom consists of several shots with each an internal thread at one end and a locking piece with an external thread at the other end; it is not only suitable for devices of the aforementioned Kind, but in conjunction with the complementary feed also for other devices with a feed and optionally a rotary drive, for example for Bar or tube pressing devices.
- the locking piece is preferably with at least a key surface for the rotationally fixed fixing of the boom section when screwing to the next one Linkage shot provided. Furthermore, the locking piece have a stop surface and inside of the rod section, a tubular filler from a Material with a relatively low specific Weight, for example made of plastic. This filler serves the opening cross section of a tubular drill pipe on the for the Passing through a flushing, cutting, lubricating or steering fluid reduce necessary measure and considering its relatively low specific weight the total weight of the pipe weft is as low as possible to keep.
- the device shown consists of a box-shaped Frame 1, in which on a not shown Carriage parallel to each other two jacks 2,3 are arranged, the piston rods 4,5 on the Support the rear end wall 6 of the housing 1.
- the two Hydraulic cylinders 2, 3 are rigid via a bolt 7 connected to each other, on the middle of another cylinder 8 is stored.
- the piston rod 9 of the middle Cylinder 8 carries one shown only schematically in Fig. 2 Console 10 on which a rotary drive 11 is mounted is.
- the drive shaft of the rotary drive 11, not shown is rotatably connected to a plug-in coupling 12 which from a chuck 14 and a locking piece 15 on End of a rod section 16.
- the boom shot 16 is aligned with a rod guide 17 on the front end wall 18 of the frame 1 and is on his front end with a slightly conical screw coupling 19 provided with an internal thread 20, which is based on the rear end of a passing first shot, for example with a drilling tool and / or a steering surface and / or a device for locating the boom tip or one already in the ground, not shown
- the internal thread can of course also be appropriate Screw threaded pieces of broaching or expanding tools, if the linkage, for example, as a pull linkage is used.
- the rod section 16 has a stepped bore 21,22, in the larger section 22 there is a tubular Filler 23 is located, the longitudinal bore 24 approximately has the same cross section as the hole 21. This packing is used to support the weight of the boom section 16 and the clear width of the bore section 21 to decrease.
- the screw coupling 19 opposite, rear End of the rod section 16 consists of a front Section 25 with an external thread 26 which with the internal thread 20 at the other end of the rod section corresponds and serves two similar boom sections to screw together.
- the front section 25 close two similar stops each with two stop surfaces 28, 29 and another Section 30 with two opposite one another Key faces 31, 32.
- the key areas own rounded lower edges, which facilitate the intervention and by turning the boom section in the chuck 14 enable axial locking on the chuck.
- the locking piece from the two sections 26.30 and two stops 27 can be radial Insert slot 33 into chuck 14 from above so that with an axial displacement of the rod section 16 the rear end 25 partially in a bowl 34th with a feed line 35 for a flushing, lubricating, Cutting and steering fluid intervenes.
- the rotary drive 11 is connected to a limit switch, not shown, who ensures that the insertion slot 33 at resting feed 14 always points upwards.
- the bowl prevents the rod section 16 or its Locking piece 15 when turning the chuck 14 out the radial slot 33 falls out. With such a turning hits at least one of the two stop surfaces 28, 29 of the stops 27 to one of two corresponding, stop surfaces not shown in the drawing Inside of the chuck 14, which acts as a driver for the boom section 16 act so that its internal thread 20 on the external thread 26 or the rear End of a boom already in the ground in Screw the shape of the threaded portion 25.
- a radially movable with respect to the linkage Sliding piece 38 with a holding claw 39 Located on the front end wall 18 of the frame 1 below the rod guide 17 with two guide jaws 36,37 a radially movable with respect to the linkage Sliding piece 38 with a holding claw 39.
- This holding claw is articulated with a two-armed hand or foot lever 40 connected, the pivot pin 41 in a vertical slot 42 of the sliding piece 38 is guided under the influence of two fixed return springs 43 stands. These return springs move the sliding piece 38 with the holding claw 39 in the rest position 7, from which the holding claw 39 with the help of the hand or foot lever 40 in the operating position according to Fig. 8 can move.
- the stop 27 adjacent to the section 25 is not imperative; it does not have to be that way either like the other attack 27. It serves to Linkage in cooperation with the claw 39 in the axial To fix direction. This is primarily necessary when the linkage is in relatively loose Soil is located and there is a risk that the forage unintentionally when moving to the rear end of the Linkage or the last link shot hits. Each after the impact force, the linkage can then be unwanted move a bit into the ground and in Coupling with the feed no longer or only with difficulty to be possible. Grabs the holding claw on the section 30 on, then the boom section in question non-rotatably fixed and limit the two shoulders left and right of section 30 the axial movement in both directions.
- Clamping supports 45, 46 are arranged on the side of the frame 1, with the help of which the frame in a starting pit can be tightened.
- the device according to the invention is such that it can not only be used in a pit. Much more it is also suitable for an arrangement on a Swivel mount that allows above-ground oblique drilling. It is not so much about the compact Construction.
- the particular advantages of the invention Quick coupling from the driven chuck on the one hand and the locking piece on the rod section on the other hand, however, are preserved.
- the device is therefore suitable for all types of earthworks with a rotating rod, especially for Manufacture and pulling or pressing expanding of Earth drilling, to destroy, replace and insert of pipes by pressing, hitting and / or pulling. The insertion can be done by pressing, pulling and Beating happen.
