Description

ROTATING TOOL FOR CUTTING MICROTRENCHES
Field of the invention
[0001 ] The present invention generally finds application in the field of digging devices and tools and particularly relates to a rotating tool for cutting microtrenches.
Background art
[0002] Tools and devices have been long known to be mounted to digging machines, for digging microtrenches on the road surface.
[0003] Such machines are designed for laying fiber optic cables and are required to have a very small width, for less invasive digging and reconstruction of the road surface.
[0004] These tools typically comprise a disk-like body which rotates about a central axis, and a plurality of trenching peaks rigidly joined to the peripheral edge of the body. These peaks have a very small size, to limit the width of the trench.
[0005] Nevertheless, a first drawback of such arrangements is that this type of trenching peaks are prone to fast wear upon extended contact with the soil and must be frequently replaced.
[0006] In order to at least partially obviate this drawback, microtrenching tools have been developed, which comprise larger trenching peaks.
[0007] WO201 5/073821 discloses a disk-shaped microtrenching tool comprising a plurality of trenching peaks angularly arranged along its peripheral edge.
[0008] The trenching peaks of this tool have a shank diameter of 2 mm and diverge from a central plane, extending away from each other.
[0009] A first drawback of this arrangement is that this tool can only partially limit the width of the trench.
[0010] Due to this drawback, road reconstruction after cable deployment becomes more time-consuming, complex and costly.
[0011 ] A further drawback is that the particular shape and location of the peaks can only partially limit their wear during trenching.
[0012] Another drawback is that this tool is particularly exposed to the vibrations caused by contact with the soil and the road surface.
Disclosure of the invention
[0013] The object of the present invention is to obviate the above drawback, by providing a rotating tool for cutting microtrenches that is highly efficient and relatively cost-effective.
[0014] A particular object of the present invention is to provide a rotating tool for cutting microtrenches, that can dig microtrenches as narrow as 5 cm or less.
[0015] A further object of the present invention is to provide a rotating tool for cutting microtrenches, that can limit the wear of the trenching peaks and requires less maintenance.
[0016] Yet another object of the present invention is to provide a rotating tool for cutting microtrenches, that is exposed to very little vibration upon interaction with the road surface.
[0017] These and other objects, as better explained hereafter, are fulfilled by a rotating tool for cutting microtrenches as defined in claim 1 .
[0018] Advantageous embodiments of the invention are obtained in accordance with the dependent claims.
Brief description of the drawings
[0019] Further features and advantages of the invention will be more apparent from the detailed description of a preferred, non-exclusive embodiment of a rotating tool for cutting microtrenches according to the invention, which is described as a non-limiting example with the help of the annexed drawings, in which:
FIG. 1 is a lateral enlarged view of the rotating tool for cutting microtrenches of the invention;
FIG. 2 is a front view of the tool of Fig. 1 ;
FIG. 3 is an enlarged front view of the tool of Fig. 2.
Detailed description of a preferred exemplary embodiment
[0020] Particularly referring to the figures, there is shown a rotary trenching tool 1 , particularly for digging microtrenches for fiber optic deployment.
Advantageously, the microtrenches formed by the tool 1 of the present invention may have a maximum width of 5 cm or less.
[0021 ] The tool 1 will be adapted to be rotatably mounted to a known digging machine or the like, not shown, for forming microtrenches in the road surface.
[0022] Advantageously, the machine may be designed for use in trenching surfaces other than asphalt, such as for example concrete, and comprises motor means, preferably of hydraulic type for driving the tool 1 .
[0023] In a preferred embodiment of the invention, the tool 1 comprises a rotatable body 2 with a central axis X and a middle plane π perpendicular to the axis X and having a circular peripheral edge 3. The body 2 is designed to be secured via a keyed hub 4 to a drive spindle of the digging machine, not shown.
[0024] The edge 3 may have a maximum thickness of 3 cm and the body 2 that is fitted to the digging machine may be protected by a matingly shaped casing for collecting debris, not shown.
[0025] Furthermore, the tool 1 comprises at least one first trenching peak 5 which is adapted to cut a rigid substrate, e.g. the road surface, for digging a microtrench therein.
[0026] The first peak 5 is secured to the circular peripheral edge 3 in an at least partially radial position and has a predetermined maximum width .
[0027] Advantageously, the first peak 5 may be rotatably inserted into a respective support 6, which is secured to the peripheral edge 3 of the body 2 by welding. As is known per se, the peak 5 may be made of tungsten carbide with special steel.
[0028] In a peculiar aspect of the invention, the tool 1 comprises at least one second trenching peak 7 differing from the first peak, and having a smaller maximum width l2. Furthermore, this second peak 7 is adapted to be secured to the peripheral edge 3 of the body in an angularly offset position relative to the first peak 5.
[0029] The maximum width of the first peak 5 may be 1 9.2mm and maximum width l2 of the second peak 7 may be 14mm.
[0030] Conveniently, the tool may comprise a plurality of first trenching peaks 5 alternating with a plurality of second trenching peaks 7 and each of them is rotatably inserted in a respective support 6, 8 which is adapted to be secured to the peripheral edge 3 of the body 2.
[0031 ] Namely, the trenching tool 1 may comprise sets 5' of first peaks 5 intervening between sets T of second peaks 7 and each set 5', T may respectively comprise at least two first peaks 5 and at least two second peaks 7, in angularly offset relationship.
[0032] In the illustrated embodiment, which shall not be intended to limit the invention, each first set 5' comprises three first peaks 5 and each second set T comprises three second peaks 7.
[0033] The three first peaks 5 of each set 5' may diverge from the center plane π of the body 2 and project therefrom at increasing distances di , d2, d3 respectively equal to 5mm, 14mm and 21 mm.
[0034] The three second peaks 7 of each set T may diverge from the middle plane π and project therefrom at distances d4, d5 respectively equal to 14mm and 25mm. That is, the two second peaks 7 of each set 7', particularly the end peaks, diverge from the middle plane π at equal distances ds.
[0035] In addition, both two successive sets 5', 5" of first peaks 5 and two successive sets 7', 7" of second peaks 7 diverge from the middle plane π with opposed divergence angles.
[0036] In an alternative embodiment of the invention, not shown, the first peaks 5 of each first set 5' may also have opposed divergence angles in alternating relationship.
[0037] The particular arrangement of the first 5 and second 7 peaks can be achieved by welding the respective first 6 and second 8 support at predetermined distances from the middle plane ττ, corresponding to those listed above.
[0038] In this arrangement, the sets 5' of first peaks 5, which are less angled than the second peaks 7, dig the microtrench to a width of 4 cm.
[0039] Later, the sets T of second peaks 7 enlarge the previously dug trench according to their respective divergence angles, to a microtrench width of 5 cm. [0040] Particularly, one set 7' of second peaks 7 may widen the trench by 0.5cm on one side of the middle plane ττ, and the next set 7" of second peaks 7 may widen the trench by additional 0.5cm on the opposite side from the middle plane ττ.
[0041 ] Of course, this configuration is only given by way of example and without limiting the invention, because the angles and arrangements of the first 5 and second 7 peaks may be slightly adjusted to form microtrenches of smaller width.
[0042] Advantageously, the sets T of second peaks 7, and particularly their supports 8, may be welded to respective unitary bases 9 that are designed to be secured to the circular peripheral edge 3 of the body and have a predetermined height h. Thus, the first peaks 5 and the second peaks
7 may radially protrude from the peripheral edge 3 by a substantially constant value p, as shown in FIG. 1 .
[0043] The trenching tool of the invention is susceptible to a number of changes and variants, within the inventive principle disclosed in the appended claims.
[0044] All the details thereof may be replaced by other technically equivalent parts, and the materials may vary depending on different needs, without departure from the scope of the invention.
