Definitions

  • the present invention refers to a protective element for a wear element of earthmoving machines, in particular, for protecting the front part of adapters of earthmoving machines.
  • the components of earthmoving machines are subject to wear, and they need protective elements to prevent or delay this wear.
  • the adapter has a rear part suitable for being fixed to the shovel, and a front part suitable for being housed inside a cavity of the wear element or tooth.
  • the rear part has an attaching part, e.g., like two legs, an upper leg, and a bottom leg, the rear part also has a connection part which connect the attaching part with de front part of the adapter.
  • the front end of the adapters is inside the cavity of the tooth when the tooth and the adapter are attached, but the connection part are exposed to the ground and to the excavated material, and that contact of the connection part of the adapters with the excavated material makes that area of the adapter be subjected to a high level of wear.
  • Adapters wear out especially in the upper part and in the lower part, the wear on the sides is reduced, because the greatest quantity of the material cross for over and bottom part of the adapters, the laterals have some protection by other adapters and shrouds.
  • wear caps are used, which protect only the upper part of the adapter.
  • Two wear caps can also be used, one on the top and one on the bottom, but in this case the sides are unprotected.
  • the protective elements may weigh more than 20 kg. in these cases, the pieces are obliged, for safety, to carry a lifting eye, which allows them to be manipulated with a crane or hoist. In these cases, the lower wear caps are very difficult to place, due to two factors:
  • one purpose of the present invention is to provide a protective element that protects the entire front perimeter of a wear element of earthmoving machines, in particular, for protecting the connection part of adapters of earthmoving machines.
  • the protective element for a wear element of earthmoving machines according to the present invention is made from one piece, comprising:
  • At least one of the side protective portions comprise an internal protrusion, and preferably both protective portions comprise an internal protrusion. That protrusion is used to guide the protective element over the adapter which have a groove to receive the protrusion, for positioning and maintaining in position the protective element.
  • the, or each, internal protrusion has a substantially parallelepiped shape defining a plurality of stop flat surfaces.
  • the backwards movement of the protective element is stopped by the back stop surfaces of the internal protrusions.
  • the upwards and downwards movements are stopped by the upper, frontal, and lower surfaces of the internals protrusions.
  • the side protective portions are preferably U-shaped, defining a central part and two lateral parts, and the, or each protrusion, is placed in the internal central part of the side protective portions, Positioning the protrusions in internal central part of the side protective portions, make the protrusions of the protective element and the groove in the adapter be less exposed to the wear, this optimized the designs of the protective elements and make them more efficiently and resistant.
  • the side protective portions are flat, the first protective portion is curved, and the second protective portion is also curved. Following the shape of the connection part of the adapter with an extra thickness for protection.
  • the protective element comprises a lifting eye, which is placed in the first protective portion.
  • the protective element according to the present invention has a collar shape.
  • the protective element does not need a pin to be fixed in position, it is self-holding between the adapter and the tooth, so as a back surface of the tooth contacts with a front surface of the protective element, maintaining the protective element in position.
  • the contact of the back surface of the tooth and the front surface of the protective element avoids the forward movement of the protective element. That is to say, the collar shape of the protective element of the present invention allows having a big frontal contact surface with the tooth, that firmly stops the forward movement of the protective element.
  • the positioning of the guides on the sides provides the following advantages: The geometries and position of the guides in wear caps is very limited. In the current wear caps, above all in small sizes, there is not much surface in the upper/lower area for these caps.
  • the frontal contact surface also increases the contact zone with the tooth on the whole perimeter of the collar.
  • the protective element is used for protecting wear elements of earthmoving machines, in particular, for protecting the connection part 10 of adapters 7 of earthmoving machines, as shown in Figures 3 and 4 .
  • the wear element or adapter has a front part 8 a rear part 7, that rear part comprises an attaching part 11 and a connection part 10.
  • the protective element 1 according to the present invention is made from a single piece, and according to the shown embodiment, has a collar shape.
  • the protective element 1 comprises a first protective portion 2, which is the upper protective portion in the use position, a second protective portion 3 opposite to the first protective portion 2, which is the lower protective portion in the use position, and two side protective portions 4.
  • the wear element or adapter is protected on their upper, lower and side parts by the protective element 1.
  • the first and second protective portions 2, 3 are curved, and the side protective portions 4 are flat.
  • the first and second protective portions 2, 3 are curved because they are apart from the shape of the adapter, these portions are significant parallel from the adapter and the tooth.
  • the side protective portions 4 are U-shaped, defining a central part and two lateral parts.
  • One or both side protective portions 4 comprise an internal protrusion 5, that is used as a contact or abutment portion with the wear elements tooth 9 and adapter 7.
  • the internal protrusion 5 is placed in both side protective portions 4.
  • The, or each, internal protrusion 5 has a substantially parallelepiped shape, defining a plurality of flat surfaces, in particular, a frontal flat surface 51, a rear flat surface 52, an upper flat surface 53, and a lower flat surface 54, as shown in Figures 1 and 2 .
  • the protective element 1 according to the present invention comprises a lifting eye 6, in particular, placed in the external part of the first protective portion 2.
  • This lifting eye 6 permits the placement and removal of the protective element 1 when the protective element 1 is heavy and it cannot be moved by hand.
  • the placement and removal of the protective element 1 according to the present invention can be done from its upper part, not been necessary to access to its lower part.
  • the protective element 1 defines frontal and rear openings, thanks to its collar shape.
  • the protective element 1 is mounted on an adapter 7 to be fixed or stopped with the wear element 7, mounted on the front part of the adapter.
