Definitions

  • the present invention relates to devices for attaching o working tools to operating arms of excavators and othe working machines, and more closely to such a device embodie as what is called a quick-attachment.
  • the invention is based on the fact that there is no simple cheap and reliable device for quick and safe attaching o digging buckets, lifting buckets and other tools to the end o operating arms, such as to the outermost beam-portion of a excavator, such a beam portion being designated the stick
  • a beam portion being designated the stick
  • pins or shafts fo such an attachment which for each exchange of tool have to b passed through openings being in alignment of matchin elements on the stick as well as on the bucket.
  • the fitting-i difficulties in connection with this conventional attachment, having regard to exchange of bucket or other tools, are great and well known as well as other problems which are connected thereto.
  • the quick-attachment in accordance with the present invention is as useful for attachment of such tools as loading buckets, forks and similar as well as digging buckets of different types to operating arms.
  • the object of the present invention is to remove the abov problems. This object is reached by a quick-action attachmen device of the type referred to in the claims. Also th particularly characterizing features of the invention ar clear from the claims.
  • FIG. 1 schematically shows the two main elements of the quick attachment in accordance with the invention mounted on digging bucket as well as on the end of an excavator arm,
  • FIG. 2 is a partially sectional elevational view of th element of the quick-attachment fixed to the machine arm,.
  • FIG. 3 is a schematical sectional view along line III-III i Fig. 2,
  • FIG. 4 is a partially sectional elevational view of th element of the quick-attachment fixed to the bucket
  • FIG. 5 is a schematical sectional view along line V-V in Fig. 2, and
  • FIG. 6 is a view similar to Fig. 1 but showing an alternative embodiment of the quick-attachment.
  • the quick-attachment in accordance with the invention shown in the drawings and described in the following includes plates on which the different parts included in the quick-attachment are mounted. At least the parts intended to be secured to the bucket itself may, however, be secured directly to the bucket without any intermediate plate in which case the wall of the bucket constitutes the base for these details.
  • the embodiment of the quick-attachment in accordance with the invention shown in Figs. 1 to 5 comprises an end element 1 secured to the end of an excavator beam 4 and to a rod 5 from a hydraulic cylinder 6 for operating the digging bucket 3 attached to the beam, and a tool element 2 secured to the digging bucket 3.
  • the end element 1 comprises a rectangular plate 10 from which two parallel webs 11, 12 extend perpendicular. These are of a length substantially corresponding to the length of the plate 10 and they are arranged symmetrically, i.e. in such a way that they are parallel to and on the same distance from each long side of the plate 10. Between these webs 11, 12 there are extended two shafts 13, 14 which, in the shown embodiment, are journalled in said webs 11, 12 and which are intended to be used for the securing to the excavator beam 4 as well as to the rod 5.
  • Shafts 13 and 14 are located a distance inwards from the ends of the webs 11, 12 and rather close to the free end edges of the webs. Closer to the plate 10 and outside the shaft 14 , there are trunnions 15, 16 mounted to the webs 11, 12 and
  • each trunnion 15, 16 is fixed in a lug 17, 18.
  • a guiding member 19, 20 is pivotably journalled onto each trunnion 15,
  • the guiding members 19, 20 include on one hand a journalling portion through which the trunnion 15, 16 extends and on the other hand a tapered pin 21 extending therefrom and being in the shape of a truncated cone the base of which is located in the journalling portion. Hence, the guiding members 19, 20 with their tapered pins 21 can be pivoted from one position in which they are pointing inclining downwardly towards the plate 10 to a position in which they point
  • th locking head 28 In the area between the webs 11, 12 and outside shaft 13 ther is a rectangular opening 26 through the plate 10 and betwee said opening 26 and the shaft 14 there is a hydraulic cylinde 27 with a wedge-shaped locking head 28 which can be moved ou over the opening 26.
  • hydraulic operation of th locking head 28 is to prefer, it can, however, be operated i some other way, e.g. by the aid of an electrical device o even by hand by the aid of a screw or toggle mechanism or th like.
  • the element of the quick-attachment in accordance with th invention, the tool element 2, shown in Figs. 4 and 5 includes a rectangular plate 40 which is intended to b mounted to a working tool by welding, screwing or the like.
  • a one short side of this plate 40 there are two lugs 41, 4 fixed which are open in the longitudinal direction of th plate 40 and in which there are through-bores 43 having th same tapered shape as the one of the tapered pins 21 and th base faced inwards towards the plate 40.
  • a locking block 48 having an opening 4 extended therethrough in the longitudinal direction of th plate 40 and of a wedge-shape corresponing to that of the locking head 28 is arranged about intermediate the guiding planes 46, 47.
  • the excavator driver When a bucket 3 is to be connected to, i.e. is to be coupled to.the beam of an excavator, the excavator driver turns the arm 4 out over the bucket 3 which then is in the resting position shown in Fig. 1. From the driver's seat the driver can see the lugs 41, 42 and he manipulates the arm forwards as shown in Fig. 1 in which position he also can see the tapered pins 21. In this position the tapered pins 21 point outwards from the plate 10 so that during the continued manipulation the pins 21 are guided towards the lugs 41, 42 and into the bores 43. The pins 21 are then adjusted into matching position in relation to the bores 43 while the plate 10 is angularly positioned outwards from the plate 40 at the end opposite to the pins 21.
  • the driver can continue to turn the beam 4 upwards and the bucket 3 is then lifted in the back and is rolled towards the teeth.
  • the plates 10 and 40 are then brought closer to each other and the locking block 48 is coming up through the hole 26 in the plate 10 simultaneously as the guiding pins 22, 23 slide along the guiding surfaces 46, 47 on the guiding blocks 44, 45.
  • the guiding pins 22, 23 may be journalled, for rotation so that they instead of sliding roll along the guiding surfaces 46, 47.
  • the distance between the lugs 41, 42 and the guiding blocks 44, 45 in relation to the guiding members 19, 20 and the guiding pins 22, 23 is such that when the tapered pins 21 are in place within the lugs 41, 42 the guiding pins 22, 23 c slide only a distance along the guiding surfaces 46, 47 befo the clamp forces start to act. Accordingly, the plates 10 a 40 are not allowed to get into contact with each other. Duri the use of the quick-attachment the different contact surface are of course worn and the plates 10 and 40 are getting close and closer and when the wearing has been so great that th plates 10 and 40 really are in contact with each other then i is time for adjustment or reconditioning of the quick attachment.
  • the wedge-shaped locking head 28 is use which, when the two elements 1 and 2 of the quick-attachmen have been moved together as much as possible by th manipulation of the driver, is brought into the opening 49 o the locking block 48.
  • the locking head 28 is kept under bia in hydraulic or mechanical way, e.g. by the aid of a compres sion spring so that it in the locking position tends to mov further and further into the opening 49.
  • the two elements 1 and 2 of the quick attachment are of course moved a little in relation to eac other and every little play then appearing is compensated b the locking head 28.
  • the parts of the guiding blocks 44, 45 provided with the surfaces 46, 47 can be fastened b the aid of screws whereby it is easy to alter the position of the guiding surfaces 46, 47 by insertion of shims.
  • the driver only needs to actuate the hydraulic cylinder 27 or corresponding mechanism so that the locking head 28 is withdrawn from the opening 49 in the locking block 48. Then, the clamping action immediately ceases and all the driver has to do is only to operate the arm 4 so that the tapered pins 21 are withdrawn from the holes 43 in the lugs 41, 42.
  • FIG. 6 there is shown an alternative embodiment of the quick-attachment in accordance with the invention.
  • This one includes as well as the previously described embodiment an end element la which is secured to the end of an excavator beam 4a , and to a rod 5a from a hydraulic cylinder 6a for operating the digging bucket 3a connected to the beam 4a, and a tool element 2a connected to the digging bucket 3a.
  • the end element la differs from the end element 1 essentially by the fact that the guiding pins 22, 23 arranged parallel to the plate 10 are substituted by pivotable guiding pins 50 which are pivotably mounted to the ends of the webs 11a and 12a.
  • the guiding blocks 44a, 45a are provided with sloping guiding planes 46a, 47a which correspond to the guiding planes 46, 4 but they are complementary shaped to the pivotable guidin pins 50 and they are, accordingly, cup- shaped.
  • Both said embodiments of the quick-attachment in accordanc with the invention are operating in corresponding way bu while in the first embodiment the contact between the guidin pins 22 , 23 and the guiding surfaces 46 , 47 more is a line s in the latter embodiment there is obtained a larger surfac for the contact between the pivotable guiding pins 50 and th guiding surfaces 46a, 47a and hence, a lower area load.
  • pivotable guiding pins 50 wil slide longer and longer towards the plate 40a along th guiding planes 46a, 47a and then, if the pins 50 were no pivotable a matching between the pins and the guiding plane could not be obtainable. Further, the pivotability gives ris to some adaptation of the guiding pins to the sloping guidin planes for such tolerance variations which might appear.
