Abstract
- a) an actuating head (1) for maintaining the tool carrier tube (T) in rotation;
- b) a vice (2) made integral with said rotating hollow means, which vice is operated by a not rotating hollow jack (50) arranged concentrically to said rotating hollow means, which jack is suitable to receive therein said tool carrier tube.
Description
- This invention relates to devices for insertion of rotating tools into the ground. Such tools are normally mounted at the end of a tube. For the sake of brevity, the word "tube " will be used herainafter for indicating any elongate drilling means which may be caused to penetrate into the ground.
- An apparatus of this type has been described in U.S. Patent No. 3,763,654. In this patent, the insertion of thin long tubes is foreseen. These can penetrate into the . ground only owing to the excavating effect of a water jet outflowing from the tube end, whereby this device can be used only in sandy grounds. The embodiment according to U.S. Patent No. 3,763,654 provides that the tool is axially and rotatably moved. The axial movement is given by three vertical jacks which cannot ensure a simultaneous advancement of the three pistons imparting the thrust, and accordingly a perfectly axial advancement of the tool. Moreover the rotary movement takes place along small circle arcs, and is controlled by one or two horizontally arranged jacks. Therefore, an even rotation at a high r.p.m. cannot be carried out.
- Additionally, the jaw grip, also controlled by three jacks, may occur any time at a different position, not exactly coincident with the axis of the device controlling the tool advancement and rotation. This could cause the distortion of the tool carrier tube and inaccuracies in hole execution.
- This device of the prior art allows only the use of drilling devices for which the rotation can be discontinuously imparted; for example, use cannot be made of tricones, diamonded tools for the drilling of rocks or alluvial grounds, etc.
- Therefore, it is the object of the present invention to impart a continuous rotation, also at a high rate of r.p.m., to a long tool carrier tube, while exerting thereon a perfectly centered thrust coaxial with the axis of rotation of said tool carrier tube.
- The above object has been achieved as specified in Claim 1. Other advantageous improvements consist in providing the hollow jack with the piston axially integral with the sleeve, while the jacket is movable along the penetration axis, so that during its stroke if controls by means of inclined planes, the radial displacement of the gripping jaws of the tool carrier tube.
- A further advantageous improvement consists in mounting the jaws as a pendulum with the suspension point integral with the sleeve.
- Preferably, the gripping jaws are interchangeable to accomodate different tube diameters.
- . A further improvement of the invention provides that the actuating head is fitted with a floating sleeve, so that the tube advancement can for sane length be independent of the advancement of the rotating head. Thus, the threads normally provided at each end of the tube lengths are not damaged during the lead-in step.
- The invention will now be further explained with reference to an exemplary embodiment as shown in the accompanying drawings, in which:
- Fig. 1 is a schematic side view showing an apparatus for pile driving on which an apparatus according to the invention is mounted;
- Fig. 2 is an axial sectional view showing the vice forming part of the apparatus;
- Fig. 3 is a sectional view taken at right angles to the apparatus axis;
- fig. 4 is a sectional view according to VWXYZ of Fig. 5 showing the actuating head; and
- Fig. 5 is a plan view of the head shown in Fig. 4.
- Referring first to Fig. 1, it will be seen that the inventive apparatus comprises an actuating head 1 mounted on a column 3 carried by a
structure 4 movable on tracks, wheels or sliding blocks 5. Said actuating head 1 is vertically driven along the column 3 by known means provided on the column, which applies axial forces relative to tube T and directed in both directions. That is forces serving both to drive the tube T into the ground and withdraw it. The actuating head 1 performs the function of causing the hollowcentral shaft 15 and sleeve 16 integral therewith to rotate by means of two hydraulic motors 23 (Fig. 4). - The
vice 2 is provided integral with thesleeve 16. Its function is that of selectively gripping and disengaging the tube T. Both said head 1 andvice 2 are hollow, so as to allow the passage therethrough of said tube T which projects below and above thereto. After the tube has been gripped, said head 1 and vice 2 move downward. When thepositions - Referring now to Figs. 4 and 5, the construction of the actuating head 1 will now be explained. The
outlet shaft 40 of eachhydraulic motor 23 can be connected to both thepinion 41 andgear 42 by means of theclutch 49. Saidpinion 41 andgear 42 respectively mesh with the gear wheels 43 and 44 integral with the shaft 45, on which thepinion 46 is also mounted. The latter drives thewheel 47 integral with thehollow shaft 15. - Said
hollow shaft 15 is slidably connected to asleeve 16 which is integral for rotation with theshaft 15, but axially free. Thesleeve 16 has anintegral flange 16a, to which theflange 37a of saidvice 2 is bolted (Figgs. 2 and 3). Thus, as soon as the free stroke of saidsleeve 16 is resumed, the axial displacement caused by column 3 can be transferred to thevice 2. The torque produced by thehydraulic motors 23, is transferred to thevice 2 which thus causes the rotation of tube T. - The
vice 2 has aring 37 coaxial with thehollow shaft 15. Saidring 37 has aflange 37a which is made integral with the flange 16a. Saidring 37 is provided withears 37b, each of which having arod 48 pivoted thereto by apin 48a. Themovable jaws 33 are secured byscrews 36 to the end ofrods 48, so that such jaws are pendulum mounted. Thus, they can be readily replaced by other jaws of different sizes, such as to acccmodate tubes T of different diameters. At the rear, eachjaw 33 has a slopingsurface 33a cooperating with the slopingsurface 27a of aplate 27 mounted on acollar 26 providing for radially displacing saidjaw 33 whenever said collar is axially moved. Said jaw 33 is held at opening position bysprings 30. - The axial movement carried out by the
collar 26 is imparted to the latter by ahollow jack 50 which does not rotate. Thejack 50 is supported by thering 37 through the twothrust bearings 21 and bushing 28 and is arranged concentrically to thering 37 and sleeve 16. It consists of ahollow piston 29 andjacket 38. Thepiston 29 is axially secured to thering 37 byscrews 29a and flat bushing 39 penetrating into anotch 39a integral with saidpiston 29. Thejacket 38 is axially movable together with thecollar 26 which does not rotate. This is provided with anotch 26, in which the flat bushing 59 slides. Bushing 49 is integral with saidjacket 38 by thescrew 24. Through the slopingsurfaces collar 26 radially operates thejaws 33. The oi],as selectively introduced by connections 20 (only one of which is shown in Fig. 2), supplies for example the chamber A, causing thejacket 38 to be upward moved and thus releasing the tube T. On the other hand, the clamping of the latter is carried out when oil under pressure is introduced into the chamber B. - Thus, it will be seen that a perfectly centered operation of the
vice 2 is ensured. This clamping can be indefinite-1y repeated at each gripping of tube T.
