The invention relates to the related technical field of elevator traction and suspension structures, and discloses a full-surrounding elevator traction and suspension structure which comprises a car frame structure composed of a portal frame and a car bottom plate, and a car section is formed in the car frame structure. According to the full-surrounding elevator traction suspension structure, the upper beam and the lower beam of the elevator car frame are both designed to be the rope returning beams, the full-wrapping mode that the two lower beam rope returning wheels with the wide span are externally wound and the two upper beam rope returning wheels with the narrow span are continuously internally wound is adopted, full-surrounding traction suspension is achieved, and a multi-point three-dimensional supporting structure is formed; and meanwhile, deflection guide wheels are installed in the moving space between the rope returning wheels, shaking of the traction rope is limited, the stability of elevator operation is ensured, stress of an elevator car is more uniform through a full-surrounding traction suspension mode, and the problem of stress concentration in the single direction is solved. The strength of the upper beam and the lower beam is fully utilized, so that the elevator can bear larger load and meet the heavy load requirement.
本发明涉及电梯曳引悬吊结构相关技术领域,公开了一种全环绕电梯曳引悬吊结构,本发明包括龙门架和轿底板组成的轿架结构,所述轿架结构内形成一个轿厢区间。本发明通过全环绕电梯曳引悬吊结构的设置将电梯轿架上下梁都设计为返绳梁,采用外绕跨距较宽的两个下梁返绳轮并连续内绕跨距较窄的两个上梁返绳轮的全包裹方式,实现全环绕的曳引悬吊,并形成多点立体支撑结构,同时在返绳轮之间的游走空间安装偏转导向轮,限制曳引绳的晃动,确保电梯运行的平稳性,并且通过全环绕的曳引悬吊方式使电梯轿厢的受力更加均匀,减少单一方向的受力集中问题。充分利用上下梁的强度,使电梯能够承载更大的载荷,满足重载需求。
