The invention relates to the technical field of elevators and discloses a freight elevator roof-rushing prevention structure which comprises an elevator shaft, a lift car is arranged in the elevator shaft, guide rails are fixedly connected to the left side face and the right side face in the elevator shaft in a front-back symmetry mode, the left side face and the right side face of the lift car are slidably connected with the guide rails through sliding sleeves correspondingly, and a roof-rushing prevention mechanism is arranged on the upper portion in the elevator shaft. The roof rushing prevention mechanism comprises a baffle which is located over the lift car and is of a concentric-square-shaped structure, sliding plates of T-shaped structures are fixedly connected to the front side and the rear side of the baffle in a bilateral symmetry mode, and sliding grooves matched with the T-shaped structures at the ends of the sliding plates are formed in the front side face and the rear side face of the upper portion in the elevator shaft. According to the top-collision-preventing structure of the freight elevator, the top-collision-preventing mechanism is matched with the buffering mechanism to block the continuously-rising elevator car, the clamping plate of the top-collision-preventing mechanism can extrude the traction wire on the top of the elevator car, the blocking force on the elevator car is further improved, the elevator car stops when approaching the top of the elevator shaft, and therefore the elevator car is prevented from colliding with the top.

    本发明公开了一种货运电梯防冲顶结构,涉及电梯技术领域,包括电梯井,电梯井内部设有轿厢,电梯井内部左右侧面上均前后对称固定连接有导轨,轿厢左右侧面分别通过滑套与导轨滑动连接,电梯井内部上方设有防冲顶机构;防冲顶机构包括位于轿厢正上方的“回”字形结构的挡板,挡板前后两侧均左右对称固定连接有T形结构的滑板,电梯井内部上方前后侧面均开设有与滑板端部T形结构匹配的滑槽。该货运电梯防冲顶结构通过防冲顶机构配合缓冲机构对继续上升的轿厢进行阻拦,防冲顶机构的夹板能够对轿厢顶部的牵引线进行挤压,进一步提高对轿厢的阻拦力度,使得轿厢在接近电梯井顶部时停止,从而防止轿厢冲顶。
