Liftable walking mechanism of protective door
The invention relates to a liftable walking mechanism of a protective door. The walking mechanism comprises a rotary supporting mechanism 1, a lifting supporting mechanism 4, a wheel shaft assembly and a coupler 2, wherein the rotary supporting mechanism 1 comprises a supporting base 11, a sliding block 12, a rotary shaft 13, a motor 14 and a speed reducer 15; the sliding block 12 is rotationally connected with the supporting base 11 and is in sliding connection with a sliding groove in an installation base; the lifting supporting mechanism 4 comprises a lead screw guide base 21, a lifting hand wheel 22, a lifting lead screw 23 and a lifting spring 26; the lifting lead screw 23 is supported on the lead screw guide base 21 in a screwed mode; the other end of the lifting lead screw 23 and the lifting spring 26 are sequentially installed in a center hole of a guide column 25; a guide rail is fixed to a base; the base is fixed to the protective door; and a bearing pedestal is in sliding connection with the guide rail. The liftable walking mechanism can ascend and descend, meets the requirements for speed reduction and braking, and is convenient to detach and replace, and the use, overhaul and maintenance convenience is improved on the basis that the protective door can be normally opened and closed.
本发明涉及一种防护门可升降行走机构，该行走机构包括旋转支撑机构1、升降支撑机构4、轮轴组件和联轴器2；所述旋转支撑机构1包括支撑座11、滑块12、旋转轴13、电机14和减速机15；滑块12与支撑座11转动连接，滑块12与安装座上的滑槽滑动连接，所述升降支撑机构4包括丝杠导座21、升降手轮22、升降丝杠23和升降弹簧26；升降丝杠23旋合支撑在丝杠导座21上，升降丝杠23的另一端和升降弹簧26依次装入导向柱25的中心孔内，导轨固定在底座上，底座固定在防护门上，轴承座与导轨滑动连接。本发明实现了可升降、满足减速刹车要求且便于拆卸更换，在保证防护门能够正常启闭的基础上，提高使用、检修维护的便利性。
