AI Technical Summary
Technical Problem
Existing mobile cranes with rope-type telescopic structures have relatively small lifting capacities and limited applicability, and their single-cylinder pin-type operation is cumbersome and inefficient.
Method used
By fixing or loosening the rope row fixing seat, the system controls whether the extension arm rope row is fixed to the telescopic arm. Combined with the electric push rod and torque limiter, the system can determine whether different rope rows are fixed, thereby optimizing telescopic efficiency and safety.
Benefits of technology
It enables heavy lifting, expands the scope of application, and improves telescopic efficiency and ease of operation, thus overcoming the shortcomings of existing technologies.

Abstract
This invention discloses a rope-type telescopic mechanism, its telescopic method, and a crane, belonging to the field of crane technology. It includes a basic boom, a telescopic boom, a telescopic cylinder, a boom extension pulley, a boom extension rope array, a boom retraction pulley, a boom retraction rope array, and a rope array fixing seat. The cylinder rod and cylinder barrel of the telescopic cylinder are respectively fixed to the basic boom and the second section of the telescopic boom. The first boom extension rope array passes around the first boom extension pulley and connects to the first rope array fixing seat and the third section of the telescopic boom. The remaining boom extension rope arrays pass around their corresponding boom extension pulleys and connect to their corresponding rope array fixing seats and the lower section of the telescopic boom mounted on their respective boom extension pulleys. The first boom retraction rope array passes around the first boom retraction pulley and connects to the first rope array fixing seat and the third section of the telescopic boom. The remaining boom retraction rope arrays pass around their corresponding boom retraction pulleys and connect to their corresponding rope array fixing seats and the lower section of the telescopic boom mounted on their respective boom retraction pulleys. This invention enables heavy lifting and solves the problems of limited lifting capacity and narrow applicability of existing rope-type telescopic structures.
