The invention discloses a lifting platform safety door with a safety lock. The lifting platform safety door comprises two door leaves, wherein one or more shaft sleeves are arranged on two opposite side beams at which the two door leaves are closed respectively; the upper and lower shaft sleeves are coaxially combined to form a pin sleeve; one of the door leaves is also provided with a linkage shaft parallel to each shaft sleeve; the linkage shaft moves upwards and downwards along the height direction of the door leaf; the side face of the linkage shaft close to the other door leaf is providedwith pin shafts in a number being consistent with the number of the pin sleeves; and the linkage shaft is drives the pin sleeve into or out of the pin sleeve. According to the lifting platform safetydoor, the linkage shaft and the pin shaft have different axle centers, and do not rotate even if the door leaves are shaken, so that the pin shaft and the pin sleeve are prevented from being separated, and the safety door is in a closed state.
本发明公开一种带安全锁的升降平台安全门,包括两门扇,两门扇闭合处相对的两边梁上分别设置有一个或多个轴套,上、下两轴套同轴组合成销套;在其中一门扇上还设置有一与各轴套平行的联动轴,所述联动轴沿该门扇的高度方向上下活动,所述联动轴上靠近另一门扇的侧面设置有数量与销套的数量一致的销轴,所述联动轴带动所述销套插入或拨出销套。本发明中由于联动轴和销轴为不同的轴心,即使门扇摇动,联动轴和销轴也不会转动,确保销轴和销套不会脱离,保证安全门的处于闭合状态。
