The invention discloses an improved cable hoisting device, and relates to the technical field of cable hoisting. The improved cable hoisting device comprises a tower frame, a cable and a moving trolley on the cable; a reel is rotatably connected to the interior of the moving trolley; a limiting disc is fixed to the outer side of the reel; and the limiting disc and the reel form a first section anda second section; fixed pulleys and movable pulleys are arranged on the two sides of the interior of the moving trolley; and a first steel wire rope and a second steel wire rope which are wound around the fixed pulleys and the movable pulleys are arranged on the outer sides of the first section and the second section. According to the improved cable hoisting device, the first steel wire rope andthe second steel wire rope are reversely wound on the reel; the first steel wire rope and the second steel wire rope can ascend and descend respectively; and in the clockwise and anticlockwise rotating process of the reel, a first non-return pawl and a second non-return pawl are used for limiting a first ratchet wheel and a second ratchet wheel respectively; and the situation of falling caused byreverse rotation is avoided, and potential safety hazards are reduced.

    本发明公开了一种改进型缆索起吊装置,涉及缆索起吊技术领域,包括塔架、缆索以及缆索上的移动跑车,所述移动跑车的内部转动连接有卷盘,且卷盘的外侧固定有限位盘,所述限位盘与卷盘形成第一区间和第二区间,所述移动跑车内部的两侧皆设置有定滑轮和动滑轮,所述第一区间和第二区间的外侧设置有与定滑轮和动滑轮缠绕的第一钢丝绳和第二钢丝绳。本发明利用第一钢丝绳和第二钢丝绳反向缠绕在卷盘上,可以进行第一钢丝绳和第二钢丝绳升降的分别操作,在卷盘的顺时针和逆时针转动过程中,利用第一止逆棘爪和第二止逆棘爪分别对第一棘轮和第二棘轮起到限位作用,避免反向转动,造成坠落的情况,降低了安全隐患。
