Definitions

  • This invention relates to the excavation field, for the construction of diaphragms, and refers, in particular, to a hydraulic bucket excavation equipment for the construction of such diaphragms.
  • diaphragms composed of a series of flanking panels arranged side by side, each panel is obtained in a generally rectangular-section excavation, extended in the direction of the diaphragm. where short sides arc confined with the short sides of the adjacent panels.
  • Excavations are generally carried out with buckets with two superposed valves, with penetration teeth and ground loading.
  • the body of the bucket is equipped with guiding elements, fixed to the body, either rigidly or through positioning and regulation devices.
  • the bucket is suspended on a surface excavation equipment, bucket lowering and lifting into the hole is achieved through one or more manouver wire lines, either of the direct fire type of lifting block type.
  • the body of the bucket is suspended from these wire lines.
  • Excavation power required to activate the valves is obtained via one or more oleodynamic cylinders in the bucket body, supplied by two flexible conduits wrapped around respective constant tension power-driven winding paddle wheels.
  • the teeth on the valves are arranged in asymetric and complementary manner.
  • the number of teeth is therefore different on both valves, making specific loads exerted on the teeth by the force of excavation.
  • valve teeth are out of phase by half a step with respect to those of the other valve to allow valve closure without any contact between the teeth.
  • one of the valves is equipped with an additional tooth (with respect to the other valve). Teeth geometry is therefore symetric vertically, on the valve rotation axis.
  • the degree of intensity exerted on each valve on closure is different.
  • the difference In torsion is mainly due to the above mentioned difference of the excavation teeth on both valves.
  • FIG. 1 that illustrate the bucket-type excavation equipment of the type used for diaphragm construction.
  • the equipment is equipped with a telescopic guide group, mounted on connection head 11, at the top of arm 10 of the crane.
  • the telescopic group can turn on the vertical excavation axis by way of rotation device 12, fixed to head 11.
  • the telescopic group includes an upper clement 13, fixed to the rotating section of rotating element 12, an intermediate element 14, that can slide telescopically inside the first, and a lower element 15, that can slide telescopically inside the second.
  • the body of bucket 16 including lateral guides 17 and standard-type valves 18, is activated by a hydraulic system Incorporated on the inside part of the body of the bucket 16, and powered by way of flexible conduits 19, is wound on paddle wheels 20, fixed to the lower section of third element 15.
  • the paddle wheels are mounted in a rotatable way on the first upper telescopic first element 13, and are equipped with an elastic hydraulic recall system to ensure a predefined, substantially constant level of tension on the flexible conduits, 19.
  • Manouver wire line 21 is fixed at 22 to an element 23 that Is fixed to the bucket body, to ensure bucket lifting and lowering. These movements correspond to the retraction and extension of the telescopic group 13-15 respectively.
  • flexible conduits are wound by the paddle wheels. The winding is controlled in order that the conduits be subjected to the specified level of tension ; during bucket lifting, bucket wheels rewind conduits automatically.
  • the telescopic group makes it possible to ensure that the panel is maintained in a vertical position during the first meters of excavation, or when the bucket body is not yet employed, with the lateral guides, in the excavation section of the panel.
  • the bucket Is removed from the hole and the rotation device 12 is used to rotate the guide group and, consequently, the bucket body, by 180°, on vertical axis x.
  • this technique involves a few disadvantages. Firstly, it limits paddle wheel diameter, that, rotating fixed to the telescopic group, must not physically interfere with the crane arm during this manouver. For this reason, paddle wheels with relatively limited diameters should be used. This limitation has a negative effect on flexible conduits, in terms of curving angles, passage section, accurate winding on the paddle wheel. Consequently, by reducing the diameter of the paddle wheel, one reduces the functionality, causing faster wear and reducing the lifetime duration of the flexible conduits.
  • wire line bucket-type excavation equipment of the type mentioned here can easily lead to wire line winding with subsequent sliding and premature wearing of the wire lines, in the event of excessive rotation, due to manouvering errors.
  • an object of this invention is to carry out an improved type of bucket excavation equipment, limiting disadvantages and limits of the said technique, as described above.
  • an object of this invention is to propose an equipment capable of carrying out precise excavations, with particular attention on eliminating, or, at least limiting torsional errors.
  • Another object of the present invention is to carry out an excavation equipment allowing use of larger diameter paddle wheels, and therefore flexible conduits capable of handling heavier oil loads and therefore more power for valve operation.
  • Another object of the present invention is to carry out an excavation equipment that is easier to manouver, in order that excavation accuracy is no longer entirely dependent on the operator's experience.
  • the equipment includes flexible conduits for bucket activation and winding means for conduit winding around a substantially horizontal axis. Winding means will be mounted on a non-rotating structural element arranged upstream of the rotating device.
  • FIG.4 which shows the excavation equipment object of the present invention, for simplicity, parts already described in previous claims, refering to FIGURES 1 to 3, will be described only to such an extent as is necessary for understanding of the invention.
  • the excavation equipment illustrated in FIG.4 includes coupling head 11 arranged at the top of arm 10 of the crane.
  • a telescopic guide group composed of coaxial telescopic elements, preferably three in number, is mounted, preferably by way of a horizontal hinge 30, on head 11.
  • the coaxial telescopic elements should, preferably, be : a first upper and external element 13, coupled on the top section of head 11, a second, intermediate element (not illustrated in FIG.4 for simplicity) and a third lower and internal element, 15.
  • the excavation force required for valve activation is obtained by way of one or more oleodynamic cylinders contained in the bucket body, and supplied by two flexible conduits, 19, wound on respective winding paddle wheels 20, motorized through constant tension (only one visible In FIG.4).
  • Lowering and lifting of bucket 16 into the excavation is obtained by way of one or more manouver wire lines 21.
  • Body 16 of the bucket is mounted in a rotatable way on a substantially paraller axis, to the excavation axis, on the lower end of lower telescopic element 15, by interposing a hydraulic rotation device 31 through which only the bucket, and not the telescopic array, can turn on the vertical excavation axis x.
  • the attachment point of wire line 21 if fixed to an element arranged upstream from rotation device 31, in the preferred embodiment, the wire line is fixed to lower element 15 of the telescopic group, preferably close to its upper end.
  • Winding paddle wheels 20 are mounted on a structural element arranged upstream from the rotation device, that does not, consequently, rotate with the bucket, in the preferred embodiment, paddle wheels are hinged on the upper element 13 of the telescopic guide group.
  • This type of configuration makes it possible to adapt paddle wheel dimensions to specific functional requirements, without technical or geometric limitations.
  • paddle wheels can be positioned as required, on the telescopic array, without protruding on the front of the telescopic group. This makes it possible to create diaphragms that can be based on possible existing vertical walls. This possibility is eliminated if a traditional type of equipment is used, illustrated in FIGS. 1 and 2, wherein at least one of the possible operating positions the paddle wheels protrude on the front of the more extended section of the equipment, and could interfere with an existing vertical wall.
  • Another advantage of the preferred embodiment of the equipment object of the present invention is based on the fact that flexible conduit (19) dimensions can be defined with optimal sections, increased according to the known technique, In order to allow loading of heavier quantities of oil. This makes it possible to increase power transmitted to the valves, and therefore excavation equipment performance.
  • wire lines are no longer subjected to torsional forces due to bucket rotation on the vertical axis, because the wire line is fixed to lower element 15 of the telescopic group (that does not rotate) at a determined point, and not on the bucket itself. Lack of torsion stability, apparent in conventional excavation equipment, is therefore eliminated.
  • FIG.5 a preferred embodiment of the hydraylic rotation device is shown, designated as a whole by numeral 31, Interposed between the telescopic group and the bucket body, for rotation of the latter.
  • the hydraulic device is composed of an upper fixed section, fixed to the telescopic group, and of a lower turning section, fixed to the bucket body.
  • the fixed section and the turning section are normally blocked by hydraulic opening lamellar brake 36.
  • Motor reducer 32 is fixed to upper telescopic element 13 of the guide group ; output transmission from the motor reduced gears onto toothed ring 33 coaxial to the telescopic group and equipped with one or more cavities (not illustrated) that can be used to engage engaging element 34, fixed, in rotation, to the lower mobile section of the hydraulic device.
  • engaging element 34 is composed of a pin, mounted in a vertical slidable way with respect to hydraulic cylinder 35, fixed to the bucket.
  • the hydraulic rotation device also includes a rotating, two-way hydraulic joint, 37.
  • the type of bucket rotation can be adjusted as required. Typically, this Is adjusted to obtain 180° rotation, to compensate for the deviation caused by the aymetric geometry of valve teeth.
  • valve 18 opening and closing should. preferably, be achieved through hydraulic two-way joint 37.
  • Another advantage of this type of configuration is that an unlimited number of rotations is possible, whilst previous solutions allow maximum rotation on 180° only, due to bucket suspension wire line winding.
  • winding paddle wheels can be mounted on the crane arm, and not on the telescopic group, although remarks made here do not illustrate this possibility.
