AI Technical Summary
In the existing elevator technology, the counterweight guide wheels are arranged backwards, resulting in the counterweight center being rearwards and the distance from the center of the car increasing, resulting in the inability to arrange the front and rear through-door structures, and the secondary beams need to be positioned and welded on site, which cannot ensure the accuracy of the dimensions.
An elevator traction frame is designed, including two load-bearing beams, frames, rope head combinations, rope head seats, counterweight guide wheels, two wheel seats and traction components. By fixedly connecting the load-bearing beams and frames, installation holes for rope head seats and rope head combinations are set to accurately locate the installation positions of the wheel seats and traction machines.
Through this design, the structure is more compact, reducing the use of secondary beams, saving materials, and effectively solving the problems caused by the rear arrangement of the counterweight guide wheels, ensuring the accuracy of the counterweight center and the reasonable arrangement of the car.
