The invention discloses an electric lifter with an abutting device. The lifter comprises a shell and a rope wheel, a mounting cavity used for mounting the rope wheel is formed in the shell, a rope inlet and a rope outlet are formed at the position, above the rope wheel, of the shell, and a rope penetrates through the rope inlet and the rope outlet and is tightly wound around a rope groove of the rope wheel; a speed reduction device is arranged in the shell, the output end of the speed reduction device is connected with the rope wheel, and a power input shaft is arranged at the input end of the speed reduction device; and a speed-limiting brake device is arranged on the power input shaft. Compared with the prior art, the electric lifter has the advantages that the speed-limiting brake device is arranged, so that the speed can be automatically limited when the rotating speed of the rope wheel is too high, and the use safety of the electric lifter is improved.

    本发明公开一种具有抵顶装置的电动升降器,包括壳体和绳轮,所述壳体内设置有用于安装所述绳轮的安装腔,所述绳轮上方的所述壳体上设置有进绳口和出绳口,绳索穿过所述进绳口和所述出绳口并紧密绕设在所述绳轮的绳槽上;所述壳体内设置有减速装置,所述减速装置的输出端与所述绳轮连接,所述减速装置的输入端设置有动力输入轴;所述动力输入轴上设置有限速刹车装置。与现有技术相比,本发明通过设置限速刹车装置,在所述绳轮转速过高时能够自动限速,提高了电动升降器的使用安全性。
