Problems solved by technology

[0003] The disadvantage of these solutions is the fact that, when the arms of the two jaws are turned, the workpiece pressed between the jaws does not have to be positioned symmetrically with respect to the jaws, since, when the jaws reach the compression phase It can have different rotation angles when

Embodiment Construction

[0012] exist figure 1 The body 1 of a hammering device according to the invention is shown in , on top of which an attachment plate 2 for a power tool is provided, for example for attaching the body to a pick by means of coupling elements 4 , 5 . In the main body 1 there is a notch 3 in which some part of the cushion of the vibrator device is located in order to attach the vibrator device to this body by means of the cushion.

[0013] exist figure 2 shown in figure 1 The vibrator device, which can be adjusted inside the main body 1 and is easily changed, is characterized in that the measured value s remains constant even if the power type of the device changes. Thus several vibrator devices 6 of different power types can be adjusted to the hammering device if a variety of hammering effects is desired. The weight and width d included in the vibrator device 6 can vary as the type of power varies. Cushion pads 9 are attached to the sides of the vibrator device 6 as structura...

Abstract

A hammering device for hammering rods, steel sections and other elongated objects into the ground, the hammering device comprising: a main body (1), which can be attached to a power tool; a vibrator device (6), which attached to said main body (1) by means of cushion pads (9); and movable jaws (10), which are adjusted for said vibrator device (6) so as to hold the hammer to be hammered with at least a side grip Objects being struck, wherein the gripping element (23) of the jaw (10) can be moved closer or farther away by means of a control unit such as a hydraulic cylinder (16). In order to keep the jaws (10) symmetrical to each other during the movement of the jaws, the jaws (10) basically comprise arms (2), (3) rigidly attached at the position of the rotary linkage (8) of the jaws , the arms are guided such that the ends of the arms (2), (3) are positioned and remain substantially close to each other during the rotational movement of the jaws (10), and the arms (2), (3 ) are connected to each other by means of a short arm (4) having a pivot member.

Description

technical field [0001] The present invention relates to a hammering device intended to hammer rods, steel sections and other elongated objects into the ground, said device comprising: a body capable of being attached to a power tool; a vibrating A vibrator device attached to a main body by means of a cushion pad and movable jaws adjusted for the vibrator device described above for clamping, at least with side clamping, a material to be hammered The object, in this case the gripping elements of the jaws, can be approached and moved away by means of an actuating unit, such as a hydraulic cylinder. Background technique [0002] A hammering device according to the above preamble is known, in which a vibrator device and a further body are attached to the body of the hammering device by means of cushion pads, in this case the further body part ground around the vibrator assembly. The jaws are rigidly or rotationally attached to the other body by means of joints. Finnish patent ...
