The invention discloses a container traction device for a fire-fighting large-tonnage elevator, and relates to the technical field of elevators. An inner hydraulic cylinder on a brake assembly starts to work and extends, the extension of the inner hydraulic cylinder drives two brake rods to rotate, stress parts at the bottoms of the two brake rods clamp a brake rotating wheel, the rotating speed of the brake rotating wheel is reduced under the action of friction force, meanwhile, the hydraulic cylinder starts to work, the angle of a whole rotating connecting rod is changed, limiting clamping plates on the rotating connecting rod clamp the rotating connecting rod and decelerate the rotating connecting rod, and the problems that an elevator cannot be quickly and stably braked, and after the elevator is powered off, the elevator is suddenly stopped without double protection, and certain potential safety hazards are brought are solved.

    本发明公开了一种用于消防大吨位电梯的货箱牵引装置,本发明涉及电梯技术领域。通过制动组合件上的内液压缸开始工作,内液压缸开始延伸,内液压缸的延伸带动两个制动杆进行转动,两个制动杆底部的受力部对制动转动轮进行夹持,制动转动轮在摩擦力的作用下转速降低,同时,液压缸开始工作,将转动连接杆整体进行角度变更,让转动连接杆上的限制夹板对其进行夹持,进行减速,解决了不能快速平稳的将电梯给刹停,并且在电梯断电后,没有双重保护将电梯急停,带来一定的安全隐患的问题。
