The invention discloses a two-stage empty and load adjusting device for truck lever weighing, which comprises a lever weighing mechanism, the lever weighing mechanism comprises a lever bracket, the middle part of a lever is rotatably mounted on the lever bracket through a rotating shaft, one end of the lever is connected with a stay wire, and a return spring is arranged between the other end of the lever and the lever bracket; the other end of the lever is provided with a contact. The novel drive-by-wire two-stage device has the beneficial effects that the novel drive-by-wire two-stage device is researched, developed and designed according to the railway trunk coal conveying special line in China, and according to the'full-empty-full-weight 'transportation characteristic of the railway coal conveying special line, the empty-weight adjusting device only sets full-empty-full-weight two-stage adjustment; compared with a traditional stepless empty and load adjusting device, the novel drive-by-wire two-stage device has the advantages that the structure is simplified and optimized, a lever weighing mechanism with a simple and convenient structure is used for replacing a traditional sensing valve, related gas circuits and pipelines are greatly saved and simplified, leakage points and the fault occurrence frequency are greatly reduced, and the safety and reliability of a system are improved.

    本发明公开了一种货车杠杆称重的两级空重车调整装置,包括杠杆称重机构,杠杆称重机构包括杠杆支架,杠杆的中部通过转轴转动安装在杠杆支架上,杠杆的一端与拉线连接,杠杆的另一端与杠杆支架之间设有复原弹簧,杠杆的另一端设有触头。本发明的有益效果:新型线控两级装置针对我国铁路干线运煤专线进行研发设计,针对铁路运煤专线“全空—全重”的运输特点,空重调整装置仅设置全空全重两级调整;新型线控两级装置相比传统的无级空重车调整装置,结构进行简化和优化,使用结构简便的杠杆称重机构代替传统的传感阀,大幅节省和简化相关气路和管道,大大减少了漏泄点和故障发生的频次,提高了系统的安全和可靠性。
