The invention belongs to the technical field of miniature cranes, and particularly relates to a miniature crane structure with a self-adaptive load adjusting function, which comprises a base, a support column is fixed at the top of the base, a cross beam is hinged to the upper side of one side wall of the support column, and a hydraulic push rod is hinged to the lower side of one side wall of the support column corresponding to the cross beam; a mounting groove is formed in the bottom of the cross beam, a pressure sensor is fixed in the mounting groove, the bottom of the pressure sensor is hinged to the outer end of the hydraulic push rod through a hinge piece, a controller and an alarm are fixed to one side wall of the supporting column, and the outer end of the short shaft on one side is connected with a heat dissipation assembly. Load monitoring is achieved, the controller can adjust the power of the servo motor through the frequency converter according to the load condition, so that the power can be automatically matched with the load, it is guaranteed that the servo motor is in the optimal working state when goods are hoisted, the servo motor is protected, and the service life of the servo motor is prolonged.
本发明属于微型吊机技术领域,具体为一种具有自适应负载调节功能的微型吊机结构,包括底座,底座的顶部固定有支柱,支柱的一侧壁上侧铰接有横梁,支柱的对应横梁一侧壁下侧铰接有液压推杆,横梁的底部开设有安装槽且安装槽内固定有压力传感器,压力传感器的底部和液压推杆的推杆外端通过铰接件铰接,支柱的一侧壁固定有控制器和报警器,其中一侧的短轴外端连接有散热组件。本发明实现对负载监测,在控制器会根据负载情况,从而利用变频器对伺服电机进行调节功率,从而使得功率能够自动化的和负载适配,从而保证吊起货物时伺服电机处于最佳工作状态,保护了伺服电机以及延长了伺服电机的使用寿命。
