The invention discloses a stable-operation limiting device for an electric hoist. The stable-operation limiting device comprises a truss, an electric hoist main body and two groups of limiting assemblies, the limiting assemblies are fixedly mounted on an anti-disengaging baffle correspondingly, each limiting assembly comprises a limiting travel switch, a limiting touch plate and a first elastic device, the limiting travel switch is fixedly installed on the anti-disengaging baffle and electrically connected with a driving device, the first elastic device is arranged on the periphery of the limiting travel switch in a sleeving mode and fixedly connected with the limiting touch plate, and the limiting touch plate corresponds to a touch plate in position. The limiting travel switch, the limiting touch plate and the touch plate are adopted, and when the touch plate moves towards the limiting touch plate, the touch plate pushes the limiting touch plate to make contact with the limiting travel switch, so that the limiting travel switch controls the driving device to stop, and the safety is improved; and meanwhile, the elastic force of a first compression spring is utilized to buffer the acting force of the contact between the limiting touch plate and the limiting travel switch, so that the loss can be reduced, and the device can be stably stopped.

    本发明公开了一种运行稳定的电动葫芦用限位装置,包括桁架、电动葫芦主体和限位组件,所述限位组件数量为两组并且分别固定安装在防脱挡板上,所述限位组件包括限位行程开关、限位触板和第一弹性装置,所述限位行程开关固定安装在防脱挡板上并且与驱动装置电联,所述第一弹性装置套设在限位行程开关外围并且与限位触板固定连接,所述限位触板与触碰板位置相对应。本发明采用限位行程开关、限位触板和触碰板,当触碰板向限位触板移动时,所述触碰板推动限位触板并使其与限位行程开关接触,从而限位行程开关控制驱动装置停止,提高安全性,同时利用第一压缩弹簧的弹力缓冲限位触板与限位行程开关的相触碰的作用力,既能减损,又能使其平稳停止。
