Abstract

dispositivo de travamento para acoplar um elemento de desgaste a um suporte em uma máquina de movimentação de terra. a presente invenção se refere a um dispositivo de travamento para acoplar um elemento de desgaste (11) a um suporte (10) em uma máquina de movimentação de terra, tendo um alojamento (9) no suporte (10) e um orifício (12) no elemento de desgaste de modo que, em uma posição montada, o alojamento (9) e o orifício (12) estejam pelo menos parcialmente alinhados. o dispositivo de travamento é introduzido dentro do alojamento (9) e compreende: - um elemento de travamento (1), - um elemento interno (2), - meios de movimento adequados para mover o elemento de travamento (1) em relação ao elemento interno (2), de forma reversível e de acordo com uma direção de movimento, entre uma posição retraída, na qual o elemento de travamento está completamente dentro do alojamento e completamente do lado de fora do orifício, e em uma posição estendida, e - meios elásticos que, na posição estendida, exercem uma força que tende a mover o elemento de travamento (1) mais próximo do elemento interno (2).locking device for attaching a wear element to a support on an earth moving machine. the present invention relates to a locking device for coupling a wear element (11) to a support (10) in an earth moving machine, having a housing (9) in the support (10) and an orifice (12) in the wear element so that, in an assembled position, the housing (9) and the hole (12) are at least partially aligned. the locking device is introduced into the housing (9) and comprises: - a locking element (1), - an internal element (2), - movement means suitable for moving the locking element (1) in relation to the element (2), reversibly and according to a direction of movement, between a retracted position, in which the locking element is completely inside the housing and completely outside the hole, and in an extended position, and - elastic means which, in the extended position, exert a force that tends to move the locking element (1) closer to the inner element (2).
