Definitions

  • a manual rammer comprising a handle at the end of which is fixed a plate forming a compacting body with an extreme compacting surface intended to come into contact with the materials to be compacted.
  • the user holds the handle in a substantially vertical orientation with the compacting body at the lower end of the handle, and applies a vertical translational movement of the handle towards the ground to bring the extreme compacting surface of the compacting element into contact with the materials to be compacted.
  • Vibrating plates are also known, weighing between approximately 50 kg and 80 kg, comprising an on-board motor (usually thermal) used to cause oscillations in a horizontal plane (parallel to the ground) and/or in a vertical direction (perpendicular to the ground).
  • a vibrating plate is generally bulky and heavy, to the point that operators regularly avoid using them so as not to have to carry them out of their truck or in.
  • Jackhammers are also known whose pick is replaced by a rod fitted at its free end with a plate forming a compacting body with a (lower) compacting surface, intended to come into contact with the materials to be compacted. Such a device remains heavy, and produces compactions of very random quality.
  • a problem addressed by the present invention is to provide a device for compacting materials such as embankments or bituminous coatings, which is inexpensive and easy to handle.
  • the invention aims to provide an electric portable device for compacting materials which allows compaction with a more consistent working quality.
  • the cam 22 rolls against a roller 24 freely rotating around a transverse axis III-III and coupled longitudinally to the compacting body 6.
  • the roller 24 is thus driven in rotation according to the movement illustrated by the arrow 25.
  • Stop means 26 make it possible to define the overshoot position ( figure 7 ) by pressing on a transverse stop flange 27.
  • the stop means 26 comprise a shock-absorbing section 28, here comprising a silentbloc 28a.
  • the stop means 26 are arranged and dimensioned so that, in the overshoot position ( figure 7 ), a gap E is maintained between the roller 24 and the cam 22 to avoid shocks between the roller 24 and the cam 22.
  • a user When using the device 1 according to the invention to compact a material on the ground (for example to compact a bituminous material in order to fill a pothole), a user directs the opening 4 towards said material (therefore towards the ground), with the longitudinal direction substantially vertical.
  • the electric motor 15 is then started and drives the compacting body 6, thanks to the actuating means 8, in an alternating movement between its retracted positions ( figures 3 And 8 ) and overtaking ( figures 4 And 7 ).
  • An alternating motion with a frequency between 11 hertz and 15 hertz has given excellent results.
  • the support surface 9 limits the risk of excessive sinking (punching) of the casing 2 and the compacting body 6 in certain localized places of the material to be compacted, and makes it possible to obtain after compaction an upper surface of the material having satisfactory flatness.
  • the user can slightly tilt the longitudinal direction I-I relative to the vertical direction (defined by gravity) in order to gradually slide the device 1 over the material being compacted.
  • the material to be compacted is in the immediate vicinity of an element forming a projection on the ground (wall, post, curb, etc.), the user can come into the immediate vicinity of this element forming a projection by coming alongside it (or around it) by means of the rectilinear section 2a of the casing 2 which has no support surface 9.
  • the compartment (3) of the casing (2) is cylindrical.
  • the retracted position corresponds to a position in which the compacting body (6) is entirely contained in the cylindrical compartment (3) of the casing (2).
  • a distal portion of the compacting body (6) projects outside the compartment (3).
  • a distal portion of the compacting body (6) by a portion having a length advantageously between 1 and 10 millimeters, preferably between 2 and 5 millimeters.
  • the distal portion of the compacting body (6) projecting from the compartment (6) in the retracted position advantageously prevents damage to the distal end of the compartment (6) during the cyclical transition from the retracted position to the overshoot position.
  • the protrusion position in which the compacting body (6) protrudes from the cylindrical compartment (3) of the casing (2) is produced according to a predetermined protrusion (d) beyond the opening (4).
  • the sidewalk (10) has, on its outer periphery, a lower connecting fillet (10a).
  • the gripping means (18) comprise a steering wheel (20) extending in a second transverse plane (P20) substantially perpendicular to the longitudinal direction (I-I).
  • the device is, according to the invention, a self-contained electric portable tool, easily usable on all types of construction sites.
