The invention relates to a method for reforming an elevator without a machine room, and the elevator without the machine room, and the method comprises the following steps of removing a top hanging wheel on the top of an elevator shaft, and installing a new traction machine the original position of the top hanging wheel; and removing an old traction machine of a shaft pit, and installing the top hanging wheel in the shaft pit to form a pit diversion sheave. Since the new traction machine is installed on the top of the elevator shaft, even if rainwater leaks into the shaft pit in rainstorm weather, the new traction machine can not be in contact with or immersed in the accumulated rainwater; the traction machine can not be soaked in the rainwater, and safe and reliable work can be guaranteedall the time; the maintenance cost for damage due to immersion can be saved; and meanwhile, the normal operation of the elevator without the machine room can be ensured.
本发明涉及一种无机房电梯改造方法及无机房电梯,其包括如下步骤:拆除电梯井道顶部的顶部吊挂轮,将新的曳引机安装于所述顶部吊挂轮的原有位置;拆除井道底坑的旧的曳引机,并将所述顶部吊挂轮安装于所述井道底坑以形成底坑反绳轮。由于新的曳引机被安装在了电梯井道顶部位置,因而即便遇到暴雨天气,雨水渗漏进入井道底坑,雨水积聚再也无法接触浸没新的曳引机,曳引机不会遭受雨水浸泡而能够始终保证安全可靠工作,不仅能够节省因水泡损坏产生的维修成本,同时还能够确保无机房电梯正常运行。
