Definitions

  • the invention is comprised in the field of earth moving machines, for example, excavators, provided with replaceable wear elements that contact the earth to perform works, such as excavation works.
  • wear elements are also known with the name ground engaging tools (GETs). They comprise elements such as:
  • the invention relates to a capsule for protecting an electronic device inside a wear element of an earth moving machine, having a central axis defining an axial direction, a front end, and a rear end opposite said front end in the axial direction.
  • Electronic devices of this type are generally intended for monitoring operative parameters of the wear element, for example, for detecting accumulated wear of the element, for detecting the falling of said element, or for accumulating operation readings for subsequent analysis.
  • the invention also relates to a wear element comprising an electronic device protected by one of said capsules, and an earth moving machine comprising at least one of said wear elements incorporating said capsule.
  • wear elements In the sector of earth moving machines, wear elements, GETs, are starting to be provided with different types of electronic devices arranged therein. These electronic devices usually comprise sensors which are used to monitor or gather information about the operations of each wear element.
  • wear elements are subjected to extreme working conditions: they are exposed to high pressures and end up withstanding high temperatures due to the friction of the wear element itself.
  • a protective element for example, a capsule intended for containing the electronic device. This capsule is formed complementary to an opening provided in the wear element intended for receiving the capsule.
  • the capsule Due to the working conditions, the capsule can end up with deformations which may even affect the electronic device. For example, dust or small particles of material are released during erosion or excavation works. These particles, known in the art as "fines," enter the exposed parts of the machinery, for example, in the attachment between the wear element and the part of the machine where said wear element is coupled, for example, between the attachment of a tooth and a tooth holder. Given that the wear end of the wear element is intended for wearing off with use, the capsule with the electronic device is usually located in the area of this attachment part between the wear element and the machine.
  • the effect of compacting the particles described above can end up applying so much pressure on the capsule that it is impossible to extract said capsule at the end of the service life of the wear element.
  • the particles compacted between the wear element and the capsule also contribute to this problem, given that fines are compacted to a very high level of hardness retaining the capsule inside the wear element. This effect can be aggravated by possible capsule deformations which further hinder capsule extraction.
  • the fact that the capsule is fixed inside the wear element has several drawbacks.
  • the main drawback lies in recycling, given that electronic components are not recycled the same way as the metallic material with which the wear element is manufactured.
  • the recycling problem is particularly relevant in the case where the electronic device comprises some kind of battery.
  • one option is to destroy the capsule when use thereof has come to an end to enable extracting remnants of the destroyed capsule from inside the wear element.
  • the batteries will end up being destroyed, which would release the contaminant products they contain.
  • Another drawback is the difficulty in recovering the electronic device, maintaining its integrity, when its service life has come to an end. That is particularly important for those devices that must be recovered, such as those that gather operation measurements of the wear element for subsequent study. Indeed, if the capsule and its contents are to be destroyed for extraction, the use of electronic devices of this type will be impossible.
  • the purpose of the invention is to provide a protective capsule of the type indicated above, which allows solving the problems described above.
  • the cover of the invention is coupled to said container by means of any removable coupling means known in the art, such as a snap-fit or click-fit. Therefore, the possible deformations mainly affect the cover, whereas the inside of the container is less affected.
  • the rear face of the flange is in contact with a support surface in the wear element.
  • the flange at the front end therefore has the technical effect of attenuating the forces due to pressure exerted by the particles built up between the wear element and the machine, and deviating part of said forces to said support surface of the wear element instead of the capsule itself. Furthermore, it hinders the passage of particles to the contact areas between the capsule and the wear element, which further reduces the problems associated with compaction.
  • the capsule is therefore more suitable for protecting the electronic device.
  • said flange has extraction means configured for extracting said container from said wear element.
  • the extraction means allow extracting the container which is the part containing the electronic device.
  • only the cover, instead of the whole capsule, would remain inside the wear element, unlike what occurs in the products of the known state of the art.
  • This solution also favors the ability to maintain the integrity of the electronic device, even when the capsule is removed from the wear element.
  • said extraction means are additionally configured for extracting said container from said cover. This further facilitates the extraction of the container: indirectly by means of extracting the container from the cover, and directly by means of extracting the container from the wear element. This minimizes the possibility of the container being lodged inside the wear element.
  • said extraction means are configured for extracting said container by means of pushing in the axial direction, which facilitates a smooth extraction, minimizing the possibility of generating lateral pushes which may end up causing damage to the container or its contents, and which may furthermore cause it to become lodged during extraction.
  • said extraction means comprise at least two threaded through holes, which allows extracting said container in the following manner:
  • said extraction means comprise three threaded through holes, such that an optimum trade-off is obtained between the conditioning factors described above.
  • said threaded holes are arranged in the axial direction parallel to said central axis, which allows extraction by means of axial pushes, such that said extraction is smoother.
  • said threaded holes are all arranged at the same distance from said central axis, preferably separated from one another at regular intervals, which allows a homogeneous force equilibrium during extraction.
  • regular intervals refer to fact that the threaded holes, which are contiguous in a circumferential direction with respect to the central axis, are arranged at the same distance from one another. For example, in the case of a circumferentially symmetrical flange with three holes, each of these holes would be located at 120°.
  • said container is open at its rear end, which facilitates the introduction of the electronic device in the capsule, given that the capsule does not have to be molded around said electronic device. Therefore, it is possible to introduce the electronic device in the container and then cover the container with the cover, thereby closing the compartment containing the electronic device.
  • the capsule has a diameter with respect to said central axis that decreases, preferably in a uniform manner, between said front end and said rear end of said capsule, facilitating both the introduction of the capsule in and the extraction thereof from the device.
  • the capsule has a frustum shape such that the inner part thereof can house the device, minimizing at the same time the length in the axial direction.
  • the capsule has a frustoconical shape which simplifies the design and facilitates extraction, particularly if the capsule did not undergo deformations.
  • the capsule further comprises first positioning means configured for cooperating with respective positioning means of said wear element for positioning said capsule inside said wear element.
  • first positioning means of said capsule comprise the outer shape of said capsule
  • respective positioning means of said wear element comprise an opening intended for receiving said capsule having a shape complementary to the shape of said capsule.
  • said first positioning means are provided on said flange.
  • This has the advantage of being able to create capsules with circumferentially symmetrical shapes with respect to the central axis, and at same the time precisely positioning the capsule in the wear element.
  • the use of circumferentially symmetrical shapes also simplifies machining.
  • said positioning means comprise the shape of the flange, particularly for an advantageous embodiment in the case of a capsule with circumferential symmetry, the flange is in the form of a circumference with a substantially straight arch on its periphery acting as positioning means by means of the complementary shape in said wear element.
  • Other preferred shapes have other positioning means such as recesses or notches intended for the same function.
  • said capsule further comprises second positioning means configured for cooperating with respective positioning means of said electronic device for positioning said electronic device inside said capsule.
  • second positioning means configured for cooperating with respective positioning means of said electronic device for positioning said electronic device inside said capsule.
  • said capsule further comprises capsule fixing means configured for fixing said capsule to said wear element.
  • capsule fixing means configured for fixing said capsule to said wear element.
  • said capsule fixing means comprise projections provided on the perimeter of said flange, which allows snap-fitting into the part of the flange.
  • said projections are longitudinally arranged, perpendicular to said perimeter. Therefore, in the case where the flange is substantially cylindrical, said projections extend in the axial direction, parallel to the central axis. If the flange has a frustum shape, the projections are arranged in a longitudinal manner, but oblique to the axial direction. This arrangement facilitates the insertion and extraction of the capsule while at the same time providing a level of coupling suitable for common wear element handling operations.
  • said capsule is manufactured in a polymer material, which facilitates its manufacture and minimizes costs, while at the same time providing a suitable level of protection.
  • said material is biodegradable such that in the event that the cover cannot be removed, it will break down, minimizing the environmental impact.
  • the invention also relates to a wear element, GET, comprising an electronic device protected by a capsule according to any of the embodiments indicated above.
  • the capsule is preferably arranged in an opening located inside the wear element.
  • the invention also relates to an earth moving machine comprising at least one wear element of the type described above.
  • said machine is an excavator comprising a shovel provided with several of said wear elements.
  • FIG. 1 show an embodiment of a capsule 1 for protecting an electronic device 2 inside a wear element 3 of an earth moving machine.
  • the capsule 1 has a central axis 4, represented by a discontinuous line. Said central axis 4 defines an axial direction.
  • the capsule also has a front end 8 and a rear end 9 opposite said front end 8 in the axial direction.
  • front and rear are used only as a naming convention for describing the coordinates relative to the capsule 1 itself, given that it can be in different positions during use, storage, and transport.
  • FIG. 1 The capsule 1 with the electronic device 2 is shown in Figures 4 , 5, and 6.
  • Figure 5 shows an exploded view of the capsule 1

  • Figures 11 and 12 show the capsule 1 inside a wear element 3 of an earth moving machine. These wear elements 3 are also known as GETs.
  • the capsule 1 of the drawings comprises a container 5 shown separately in Figures 7 to 10 .
  • said container 5 extends in the axial direction from said front end 8 of the capsule 1, such that the front end of the container 5 corresponds to the front end 8 of the capsule.
  • the container 5 is provided with an inner chamber 53 configured for housing said electronic device 2.
  • Figures 5, 6 , and 10 show that said container 5 has a front part 51 and a rear part 52, the front part 51 being provided with a flange 7.
  • both front part 51 and rear part 52 are integrally attached forming single body, particularly they are manufactured as a single part.
  • the container 5 is open at its rear end such that the electronic device 2 can be introduced into said container 5 through its rear end.
  • the rear end of the container 5 is not open.
  • the capsule also comprises a cover 6 that can be removably coupled to said container 5 and configured for covering said rear part 52 of said container 5.
  • the rear part 52 of the container 5 has an annular recess 54 in the area where it is attached with the front part 51.
  • the cover 6 has an annular protuberance 64 at its front end. Said annular recess 54 and said annular protuberance 64 cooperate with one another as coupling means, allowing the cover 6 to be removably coupled to the container 5.
  • Other embodiments have several of said annular recesses in the rear part 52 and several corresponding annular protuberances in the cover 6, thereby achieving a stronger coupling.
  • Other embodiments have other types of coupling between the cover 6 and the container 5.
  • the cover 6 covers the container 5 right up to the rear end of the flange 7: the container 5 can be inserted into the cover 6 and said cover 6 acts like a cap, tightly covering the container 5.
  • a section view showing the interaction and the relative positions between the container 5 and the cover 6 can be seen in Figure 4 . It is seen in the same Figure 4 , and separately in Figure 10 , that the rear part 52 of the container 5 has a cylindrical tubular shape, whereas the cover 6 has a frustum shape, particularly a frustoconical shape which facilitates the extraction of the capsule from inside the wear element 3.
  • This embodiment allows the capsule 1 to have a diameter with respect to the central axis 4 that decreases between the front end 8 and the rear end 9.
  • Other embodiments have other profile types, for example, partially staggered profiles, profiles having a frustum shape but without circumferential symmetry, etc.
  • said flange 7 has extraction means 10 configured for extracting said container 5 from said wear element 3.
  • Other embodiments do not have extraction means 10.
  • the extraction means 10 comprise three threaded through holes in the axial direction located at regular intervals of 120° and at the same distance from the central axis 4, all of them being parallel to said central axis 4, as shown in Figure 9 .
  • the capsule 1 further comprises first positioning means 11 configured for cooperating with respective positioning means of said wear element 3 for positioning said capsule 1 inside said wear element 3.
  • Figure 11 shows the capsule 1 inserted into the wear element 3.
  • the way in which said first positioning means 11 are provided on said flange 7 and comprise the shape of the flange 7 can be seen in said figure, for the case of the example.
  • the flange 7 of the example is in the form of a circumference with a substantially straight arch on the periphery thereof acting as first positioning means 11. It can be seen in Figures 2 , 3 , 8, and 9 that said arch is arranged between two of the through holes. Therefore, given that the wear element 3 has a complementary shape, the capsule 1 can only be inserted into the wear element 3 in a specific position.
  • Other preferred shapes have other positioning means such as recesses, notches, or even combinations thereof.
  • the capsule 1 further comprises second positioning means 12 configured for cooperating with respective positioning means of said electronic device 2 for positioning said electronic device 2 inside said capsule 1.
