The invention provides a three-door passenger elevator without a machine room, and belongs to the technical field of elevators. The lift car is arranged in the lift car frame, and the outer wall of the lift car is connected with the lift car frame; the bottom of the lift car is provided with bevel edges arranged in pairs. The lift car frame comprises an upper beam, an auxiliary upper beam, an auxiliary lower beam, a lower beam, pull rods and stand columns. The upper beam and the lower beam are arranged in parallel and are parallel to a connecting line of midpoints of the pair of bevel edges; the upper beam and the lower beam are connected through the stand columns to form a frame-shaped structure. The auxiliary upper beam and the auxiliary lower beam are arranged in parallel and are parallel to the connecting line of the midpoints of the other pair of bevel edges. The auxiliary upper beam and the auxiliary lower beam are connected through a pull rod to form a frame-shaped structure; diversion sheaves are connected to the two ends of the auxiliary upper beam. The lift car frame forms center suspension for the lift car, the stress is better, the balance is good, and the stability of the three-door elevator structure is improved; the diversion sheave is arranged at the bottom of the lift car, and the requirements of the elevator for the pit depth and the top layer height are lowered.

    本发明提供了一种三开门无机房乘客电梯,属于电梯技术领域,包括轿厢和轿厢架;轿厢设置在轿厢架的内部,轿厢的外壁与轿厢架连接;轿厢的底部具有成对设置的斜边;轿厢架包括上梁、副上梁、副下梁、下梁、拉杆和立柱;上梁与下梁平行设置,且与一对斜边的中点的连线平行;上梁与下梁之间通过立柱连接,形成框型结构;副上梁和副下梁平行设置,且与另一对斜边的中点的连线平行;副上梁和副下梁之间通过拉杆连接,形成框型结构;副上梁的两端连接有反绳轮。本发明轿厢架对轿厢形成中心悬吊,受力更好,平衡性好,提高三开门电梯结构的稳定性;反绳轮设置在轿厢底部,降低了电梯对于底坑深度和顶层高度的要求。
