The invention aims to provide a lifting hook device for hydraulic weighing so as to improve the weighing accuracy and the bearing capacity of a lifting hook, and the lifting hook device is convenient to maintain. The lifting hook device for hydraulic weighing comprises a lifting hook and a connecting seat, wherein the lifting hook device comprises a hydraulic cylinder, a piston is mounted at the top end of the hydraulic cylinder, the connecting seat is fixedly connected with a cylinder body of the hydraulic cylinder, and the lifting hook is fixedly connected with the piston; and the lifting hook device further comprises a hydraulic pressure sensor used for detecting the internal pressure of the hydraulic cylinder and a data processor which is in communication connection with the hydraulic pressure sensor and converts pressure information of the hydraulic pressure sensor into lifting hook lifting weight information. Compared with the weighing principle of a traditional tension sensor, the lifting hook device indirectly weighs the weight of the lifted weight by detecting the hydraulic pressure, has the advantages of being large in bearing range, convenient to maintain and high in reliability, cannot be influenced by shaking of the lifting hook during weighing, and is more accurate in weighing.
本发明的目的是提出一种液压称重的吊钩装置,以提高称重的准确性和吊钩的承载能力,并方便维护。本发明的液压称重的吊钩装置包括吊钩和连接座,关键在于,该吊钩装置包括顶端安装有活塞的液压缸,所述连接座与液压缸的缸体固定连接,所述吊钩与活塞固定连接;该吊钩装置还包括用于检测液压缸内部压力的液压压力传感器,以及与液压压力传感器通讯连接,将液压压力传感器的压力信息转换为吊钩吊运重量信息的数据处理器。相比于传统的拉力传感器的称重原理,本发明的吊钩装置通过检测液压压力的方式来间接称量吊运重物的重量,具有承载范围大、维护方便、可靠性高的优点,而且,称重时不会受到吊钩晃动的影响,称量更加准确。
