ARRANGEMENT FOR THE REMOVABLE COUPLING OF A TOOL WITH A MANOEUVRABLE ARM OF A WORKING MACHINE

摘要

An arrangement for removable coupling of a tool with a working machine includes a first part with opposing indentions, which is supported by the tool, and a second part that is supported by a maneuverable arm, which includes shafts to be introduced into the indentations, a lever with which the shafts can be moved away from each other, and a locking mechanism for the displacement of the shafts. One of the shafts is united at a joint with a first arm section, and another shaft is united at a joint with a second arm section. The arrangement also includes at least one knee lever joints, one of which demonstrates two levers united with the shafts.

1. An arrangement for removing coupling of a tool with a working machine, the arrangement comprising:
a first part that is supported by the tool and that comprises a first and a second indentations in essentially U-shaped located opposite to and at a distance from each other, a second part that is supported by a manoeuvrable arm that is a component of the working machine and that comprises a first shaft and a second shaft that are introduced into the first and second indentations, respectively in the coupled condition of the arrangement, a lever with which the first and the second shafts are coupled in such a manner that they are allowed to move towards and away from each other, and a locking mechanism located between the first and the second shafts for the displacement thereof towards and away from each other, and for introduction of the first and the second shafts into the respective indentations, wherein the first shaft is coupled with a rigid first arm section that is a component of the manoeuvrable arm, the second shaft is united at a joint with a second arm section of the manoeuvrable arm that is mobile relative to the first arm section, the lever comprises at least one pair of knee lever joints, each knee lever joint comprising a first lever and a second lever, the first lever and the corresponding second lever are coupled at their opposing ends with the first shaft and the second shaft respectively, and the locking mechanism comprises one or several control and actuator means that can be activated through remote control and that operate between the first lever and the corresponding second lever for the displacement of the first and the second shafts from each other to have a tension-based interaction with the bottom of the respective indentations.
