The invention relates to the field of gauge-changeable tests, and provides an axle box unlocking device and a bogie gauge-changeable test bed. The axle box unlocking device comprises an axle box unlocking mechanism. The axle box unlocking mechanism comprises a fixedly-arranged counter-force support, a longitudinal actuator which is horizontally arranged and penetrates through the counter-force support, an adjusting support fixed to the extending end of the longitudinal actuator, and an unlocking rod which is horizontally installed on the adjusting support and can move up and down along the adjusting support. According to the invention, unlocking and locking of the gauge-changeable bogie during track operation can be effectively simulated to verify whether the unlocking function of the gauge-changeable bogie can meet the design and use requirements or not.
本发明涉及变轨距试验领域,提供轴箱解锁装置及转向架变轨距试验台。轴箱解锁装置包括轴箱解锁机构,所述轴箱解锁机构包括固定设置的反力支座,水平设置并穿过所述反力支座的纵向作动器,固定在所述纵向作动器的伸出端的调节支座,以及水平安装在所述调节支座上并可沿所述调节支座上下移动的解锁杆。本发明可以有效模拟变轨距转向架在轨道运行时进行解锁和锁紧,以验证变轨距转向架的解锁功能能否满足设计及使用要求。
