Crushing equipment and idle hitting detection method and device for breaking hammer in crushing equipment
The invention discloses crushing equipment and an idle hitting detection method and device for a breaking hammer in the crushing equipment. A working device of the crushing equipment comprises a movable arm and the breaking hammer, and the idle hitting detection method for the breaking hammer in the crushing equipment comprises the steps that the device gravity torque of the working device relative to a preset fixed point is determined; the pressure of a movable arm oil cylinder is obtained, and the oil cylinder thrust moment of component force of the pressure of the movable arm oil cylinder in the reverse direction of gravity relative to the fixed point is calculated according to the pressure of the movable arm oil cylinder; And when the gravity moment of the device is greater than the oil cylinder thrust moment, it is judged that the breaking hammer is idle. Therefore, whether the breaking hammer is idle or not can be automatically identified in the working process of the breaking equipment so that the operation requirement for an operator can be lowered, the working efficiency is improved, the service life of the breaking hammer is prolonged, and intelligent breaking operation is made available.
本发明公开了一种破碎设备、破碎设备中破碎锤的空打检测方法及装置，所述破碎设备的工作装置包括动臂和破碎锤，其中破碎设备中破碎锤的空打检测方法包括：确定所述工作装置相对于预设固定点的装置重力力矩；获取动臂油缸压力，根据所述动臂油缸压力计算所述动臂油缸压力在重力反方向的分力相对于所述固定点的油缸推力力矩；当所述装置重力力矩大于所述油缸推力力矩时，判定所述破碎锤空打。由此可以在破碎设备工作过程中自动识别破碎锤是否空打，从而可以降低对操作手的操作要求，提升工作效率，延长破碎锤寿命，实现破碎操作智能化。
