The invention relates to the technical field of elevators, and discloses a machine room traction type large-tonnage elevator which comprises a bearing beam, a control center is fixedly installed on the left side of the upper surface of the bearing beam, and a traction machine is fixedly installed in the middle of the upper surface of the bearing beam. In this way, the clamping head is movably connected with the traction wheel, when accidents such as falling of the lift car happen, an electromagnetic coil in the traction wheel can be triggered to be conducted and powered on, then magnetic attraction force is generated, the clamping head is attracted out of the permanent magnet, and therefore the permanent magnet stretches out and can be limited and clamped through a baffle ring; according to the large-tonnage elevator, the clamping effect of the permanent magnet and the baffle ring can be guaranteed, so that a certain auxiliary traction force is provided for falling of the elevator car when an accident happens to the elevator car, the stress of the safety tongs is reduced, the situation that the traction rope is directly separated from the traction wheel after being broken at a certain position is avoided, and the use safety of the large-tonnage elevator is improved.

    本发明涉及电梯技术领域,且公开了一种有机房曳引式大吨位电梯,包括承重梁,所述承重梁的上表面左侧固定安装有控制中心,所述承重梁上表面的中部固定安装有曳引机,该有机房曳引式大吨位电梯,通过在曳引绳上均匀设置有卡接头,这样使得卡接头与牵引轮活动连接,并且在轿厢发生下坠等意外情况时,可以触发牵引轮内的电磁线圈导通接电,进而产生磁吸力,使得卡头被从永磁铁中吸出来,这样永磁铁伸出会通过挡环进行限位卡接,可以保证永磁铁与挡环保持卡接的效果,这样在轿厢发生意外情况时为轿厢下坠提供一定的辅助牵引力,降低安全钳的受力,也避免曳引绳在某处断裂后直接与牵引轮脱离,提高了该大吨位电梯使用的安全性。
