The invention discloses an electric lifting crossing device which comprises a shell, a power system, a braking system and a control system are arranged in the shell, the power system comprises a motor, a speed reducer and a power shaft, the speed reducer is connected with the motor, the power shaft is inserted into the motor, and a power gear is arranged on the power shaft; the brake system comprises a band-type brake, a brake gear and a brake pad are arranged in the band-type brake, the power shaft is inserted into the band-type brake, and the power gear is nested in the brake gear; the control system comprises a control panel, the control panel is electrically connected with the band-type brake, the control panel can control a brake gear in the band-type brake to be meshed with the power wheel, the band-type brake can complete automatic braking and manual braking of the electric lifting crossing device, and the band-type brake is controlled to lock a power shaft of the motor according to the control panel during automatic braking. And the band-type brake can be unlocked through the handheld part, so that the device descends within a certain speed range, it is guaranteed that a user can safely descend when the device cannot work normally and is stuck, and therefore the safety of the electric lifting and crossing device in the lifting process is better guaranteed.

    本发明公开了电动升降横渡装置,包括:壳体,壳体内设置有动力系统、制动系统和控制系统,动力系统包括电机、减速机和动力轴,减速机与电机连接,动力轴插接在电机内,动力轴上设置有动力齿轮;制动系统包括抱闸,抱闸内设置有制动齿轮和刹车片,动力轴插接在抱闸内,动力齿轮嵌套在在制动齿轮中;控制系统包括控制板,控制板与抱闸电连接,控制板能够控制抱闸内的制动齿轮与动力轮啮合,抱闸能够完成电动升降横渡装置的自动刹车和手动刹车两种工作,自动刹车时根据控制板来控制抱闸抱死电机的动力轴,还可通过手持部来解锁抱闸使装置在一定速度范围内下降,保证使用者在装置无法正常工作卡死时也能安全下降,从而更好的保证电动升降横渡装置升降过程中的安全。
