Definitions
- the subject of the present invention is a percussion device of the rock breaker type, comprising a body in which is slidably mounted a piston driven alternately by an incompressible fluid under pressure, this body containing part of a tool which is guided in translation in a wear sleeve, the end of the tool located inside the body being subjected to repeated shocks from the piston, while the other end protrudes from the body and is intended to bear on the rock or the like to be destroyed .
- Such an apparatus is intended to be carried by a machine, such as a backhoe or a backhoe, for use in demolition or breaking of blocks in quarry.
- the wear bushing (s) which guide the tool in translation are generally assembled in the body of the device, either by diametric tightening, or by keying, or else are made captive between two parts of the body of the device.
- the tool is retained in the axial direction of movement by one or more transverse keys penetrating into a transverse groove that the tool comprises, and into the bore of the lower part of the body of the apparatus, called guide before.
- the body of the device is, for its part, mounted in a frame which makes it possible to hold the device on the carrier machine and to protect it from external shocks.
- the chassis holds the body of the device using conventional assembly means independent of those mentioned above.
- the object of the invention is to provide a percussion device of the rock breaker type, which has a simple structure, and in which the main components are assembled in a simple and rapid manner.
- At least one of the tool retaining pins passes through aligned holes made in the body, in the wear bushing, and projects beyond the inside the internal cylindrical space of the sleeve, the tool having a transverse groove for the passage of the key.
- the tool retaining means are used to secure the wear bushing in the body.
- the sleeve has a through notch, perpendicular to the axis of the sleeve, and extending over a part of the periphery thereof.
- the distance between the upper shoulder of the socket forming a stop for the tool and the lower edge of the part of the key projecting into the socket is less than the distance between the end of the tool intended to come into abutment against the shoulder and the edge of the groove situated on the side of the free end of the tool.
- this apparatus comprising a tubular chassis of circular or non-circular section, inside which the body is mounted, and which is provided with means of attachment to a machine
- the tubular chassis has transverse holes corresponding to those formed in the body to allow the passage of each assembly key which also passes through the socket, the body and ensures the retention of the tool.
- the assembly means defined above therefore also serve to secure the tubular frame to the body.
- the latter in order to locally reinforce the tubular part of the chassis, the latter includes bosses in the zones into which the holes open for the passage of each key.
- the bosses are provided with housings for mounting retaining circlips for each key.
- Figure 1 is an exploded perspective view of a first device
- Figure 2 is a longitudinal sectional view in the assembled position;
- Figure 3 is a cross-sectional view along the line III-III of Figure 2;
- Figure 4 is a perspective view of a tubular frame for mounting the body of the apparatus of Figures 1 to 3;
- Figure 5 is a longitudinal sectional view of the device mounted in the frame of Figure 4;
- Figure 6 is a cross-sectional view of another device mounted inside the tubular frame, this sectional view being taken along line VI-VI of Figure 5;
- Figure 7 is a cross-sectional view of another device mounted inside a tubular frame of non-circular section.
- Figures 1 to 3 show a first device comprising a body 2 equipped with a socket 3, inside which is slidably mounted a tool 4 of circular section.
- the body 2 has a bore 5, in which a piston 6 is slidably mounted, the reciprocating movement of which is ensured by a hydraulic fluid directed by a distributor 7 connected to high pressure 9 and low pressure 10 conduits.
- the tool 4 has a groove 12, in which is engaged a transverse key 13, which passes through two holes 14 formed in the body 2, as well as a through notch 15 formed in the socket 3. This key can be held in place with pins 16. It should be noted that the dimension of the groove 12, considered in the axial direction, is greater than the diameter of the key 13.
- the distance between the shoulder 17 of the sleeve 3 forming an upper stop for the tool and the lower edge of the part of the key 13 projecting into the sleeve is less than the distance between the end of the tool intended to bear against the shoulder 17 of the sleeve and the edge of the groove 12 located on the side of the free end of the tool.
- the key 13 therefore fulfills a double function, on the one hand, of axial retention of the tool 4 when the device is lifted and, on the other hand, of locking the socket 3 inside the body 2.
- FIG. 4 represents a tubular chassis 20 inside which is intended to be mounted the body 2.
- This chassis comprises a fixing plate 22 on a carrier machine whose arm is designated by the general reference 23.
- the chassis comprises two holes coaxial 24 opening at two bosses 25 locally reinforcing the tubular part of the chassis. These two holes 24 serve for the passage of the key 13 which already carries out the axial retention of the tool 4 and the fixing of the socket 3 in the body 2.
- FIG. 6 shows an alternative embodiment of this device, seen in cross section along the line VI-VI of Figure 5.
- the device comprises two keys 13 arranged symmetrically on either side of the tool 4 , the latter then having two symmetrical grooves 12.
- the bosses 25 are housings for retaining rings 26 for holding the keys 13.
- FIG. 7 represents a device similar to that of FIG. 6, but in which the body 2 and the chassis 20 have a rectangular shape.
- the blocking in rotation of the body 2 and of the chassis 20 is obtained by the association of the two rectangular shapes embedded in one another.
- the keys 13 realize the rotation blocking of these two parts.
- the number of keys 13 implemented depends on the geometry of the tool and the power of the percussion device.
- the invention brings a great improvement to the existing technique by providing an impact device of simple structure, and in which several components are assembled in a simple and rapid manner using keys fulfilling several functions. .
- the invention is not limited to the sole embodiments of this device, described above by way of examples, on the contrary it embraces all variants.
- the chassis could not be tubular, but formed by braced plates, without thereby departing from the scope of the invention.
