The invention discloses an elevator with an underneath type traction machine. A pulley block of the elevator is installed on a supporting beam at the top of a hoistway. One end of the compensation rope is connected to the top of the car and upwards bypasses the pulley block, and the other end is downwards connected to the top of the counterweight; the front end of the traction rope wound out of the traction wheel is fixedly connected to the bottom of the lift car, and the rear end of the traction rope is fixedly connected to the bottom of the counterweight. The traction machine drives the traction wheel through a main shaft of the traction machine. The traction wheel and the traction machine are lifted through a traction rope, are arranged at the bottom of the hoistway and are higher than the hoistway floor by a certain distance; at least one end of the traction guide rail is fixedly connected with the hoistway floor; a guide device is arranged at the matching position of the traction machine and the traction guide rail, so that the traction machine can freely slide up and down along the traction guide rail. According to the elevator with the underneath type traction machine, noise can be effectively reduced, and the load of the main shaft of the traction machine is relatively small.

    本发明公开了一种曳引机下置式电梯,其滑轮组安装于井道顶部的支撑梁;补偿绳一端连接到轿厢顶部,向上绕过滑轮组后,另一端向下连接到对重顶部;从曳引轮绕出的曳引绳,前端固定连接到轿厢底,后端固定连接到对重底;曳引机通过其主轴驱动曳引轮;曳引轮及曳引机通过曳引绳吊起,设置于井道底部并且高于井道地板一定距离;曳引导轨至少一端与井道地板固定连接;曳引机与曳引导轨配合处有导向装置,使得曳引机能沿着曳引导轨做上下自由滑动。本发明的曳引机下置式电梯,可有效降低噪声,曳引机主轴载荷相对较小。
