Definitions

  • the present invention relates to a concrete breaker pliers.
  • This type of tool is used for the demolition of reinforced concrete structures and generally mounted at the end of the boom of a hydraulic shovel instead of a bucket.
  • These devices generally consist of a jaw with two arms fitted with teeth, articulated on a frame which is itself rotatably mounted and further comprise a shear arranged between the arms and capable of cutting the irons and other metal fittings.
  • shears are impractical to use and ineffective. Indeed, the shears are located at the bottom of the jaw and in the immediate vicinity of one of the arms of the jaw which constitutes one of the two sectioning members of said shears.
  • the introduction of the irons to be cut inside the shears is difficult because the latter is located at the bottom of the pliers in a place which is very difficult to see from the control cabin of the machine; in addition, the opening of the shears is very small so that it is necessary to work, most of the time, blind, grope to engage the irons and to repeat it several times to cut a bundle of irons. Finally, the maximum opening of the shears being obtained by the maximum opening of the pliers, this can pose serious problems when it is necessary to cut irons in small, congested or narrow access spaces.
  • Document DE-A-2,722,258 also discloses pliers provided with shears. However, it is a device comprising a common, fixed jaw arm, cooperating with a gripper arm and a shear arm arranged in parallel and controlled independently.
  • the object of the present invention is to overcome these various drawbacks by proposing another combination of means ensuring both the function of concrete clamps and the shears function, in a much more practical and efficient manner.
  • the subject of the invention is a concrete breaker clamp of the type comprising a frame mounted to rotate, carrying both two clamp arms, at least one of which is movable relative to the frame and shearing members, characterized in that said frame is formed of two flanges and in that the shearing members are mounted, on the one hand, on at least one fixed arm formed by an extension of one of the flanges and, on the other hand, on said movable arm of the clamp, said fixed and movable arm being in side-by-side position in the position of maximum opening of the clamp, so as to give the shears its maximum closure in this position.
  • Such a device is much easier to handle and effective because the shears are located at the end of the pliers and no longer at the bottom or on the external lateral side of the pliers. Its opening is much larger and corresponds to the minimum spacing of the clamp, which makes it possible to shear in one go, after a direct, frank and without engagement groping, several grouped irons. Finally, a single cylinder controls both the pliers and the shears.
  • the invention also aims to improve the efficiency of the shears and pliers organs by allowing easy adjustment and / or replacement of the blades or teeth.
  • the concrete breaker pliers illustrated in FIGS. 1 to 3 comprises a frame 1 formed by two flanges 2 and 3 on and between which two arms 4 and 5 concrete breakers are articulated.
  • the assembly 1-5 is mounted infinitely rotatable, by hydraulic motor and rotating joint, on an adapter part 6 of conventional design, intended to be mounted, in the known manner, at the end of the boom of a shovel mechanical for example. Between the part 6 and the frame 1 is interposed the rotation device with its fixed ball ring 7; hydraulic regulation supporting untimely efforts on the rotation control assembly.
  • the arms 4 and 5 constitute levers flanked by pins 8 and 9 engaged in bearings 10 produced in the two flanges 2 and 3.
  • the angular movement of the arms 4 and 5 is limited by a stop 13 integral with the frame 1 and an arcuate opening 14 formed in each arm and in which the stop 13 can slide.
  • One of the flanges (2) has, on one side, an extension in the form of an arm 14, the end of which constitutes one of the arms of a shear, the other arm of which is formed by the arm 5 of the pliers .
  • the active members of the shears consist of cutting blades 15 and 16 mounted removable respectively on the flanks opposite the arms 5 and 14 respectively.
  • the arrangement of the arm 14 is such that in the position of maximum closing of the clamp (4, 5) as illustrated in FIGS. 1 and 3, the opening of the shears (5, 14) is maximum, while in the maximum open position of the clamp ( Figure 2), the shears are completely closed.
  • the blades 15 and 16 are arranged at the ends of the arms 5 and 14 in order to grip the irons with the largest possible opening and greater ease of access to and grip of the irons.
  • FIG. 7 illustrates the shape and mounting of the blades 15 and 16.
  • These consist, in accordance with the invention, of an elongated plate provided on one of its faces with a series of teeth 17 whose profile asymmetrical is determined so as to retain the irons in the shears and prevent them from sliding outside when the arms 5, 14 are closed.
  • each tooth 17 comprises a side 17a substantially vertical, with respect to the general plane of the blade plate, a side 17b slightly inclined towards the outside of the shears and a heater 17c for connection between the two sides 17a. , 17b, avoiding any sharp edge and therefore fragile at the end of the teeth.
  • the removable mounting of the blades 15 and 16 allows a re-sharpening of the cutting edge by grinding one of the lateral sides of the blades.
  • the teeth 11 of the concrete breaker are preferably made up of parts (FIG. 8) comprising a frustoconical anchoring foot 19 engaged in a housing of corresponding shape formed in the receiving arm (4, 5) and retained in place by a group 20
  • This assembly makes it possible to transfer onto said frustoconical housing all of the forces exerted on the tooth 11, the external part 21 of which is slightly set back from the face opposite the support arm.
  • FIG. 4 illustrates a variant of the device of FIG. 3 according to which a second arm 14 ′, parallel to the arm 14, is provided by means of an extension of the flange 3.
  • This arm 14 ′ is provided with a blade section 16 ′ parallel to the blade 16, the arm 5 of the clamp moving between the two fixed arms 14, 14 ′.
  • the concrete breaker pliers comprises a movable arm 5 also constituting one of the elements of the shears, exactly as in the embodiment of FIG. 3, but this arm 5 cooperates with a arm 4 ′ fixed, no longer mobile, and formed from an extension of the two flanges 2 and 3.
  • the cylinder 12 for controlling the arm 5 is anchored at 22 to the frame 1.
  • Figure 6 illustrates a variant of the device of Figure 5 in which the fixed arm 14 of the shears is lined with a second fixed arm 14 ′ as in the embodiment of Figure 4, the frame 1 thus having a general shape of U.
  • the invention is obviously not limited to the embodiments shown and described above, but on the contrary covers all variants thereof, in particular as regards the shapes and arrangements of the blades 16, the teeth 11 and the various arms 4, 5, 14, 4 ′, 14 ′.
