AI Technical Summary

Technical Problem

Traditional movable winches have more manual operations during prestressed inverted U-shaped steel beam traction, and are difficult to move and fine-tune, resulting in low construction efficiency and poor stability.

Method used

A self-walking winch system is designed, including a body support platform, a walking mechanism, a hoist assembly and a centering mechanism. The walking mechanism moves the body support platform along the corridor direction. The hoist assembly monitors the position of the wire rope in real time through the centering mechanism, and automatically adjusts the movement of the hoist body to ensure that the output end of the wire rope is always maintained in the middle position.

Benefits of technology

It improves the conversion efficiency of the equipment between different construction locations, reduces manual operation, improves the performance of traditional movable hoist, improves the stability and efficiency of traction operations, and ensures the accuracy and safety of steel strand traction.

Abstract

The invention discloses a self-walking winch system for prestressed inverted U-shaped steel beam traction, a body supporting platform of the system is located in a corridor, the platform can be moved to the position below a hole channel to be subjected to beam penetrating through a walking mechanism, and a winch assembly comprises a centering mechanism and a winch body. A centering mechanism monitors the posture of the steel wire rope through a sensor and transmits data to a control system so as to guide the body to move and keep the output end of the steel wire rope centered all the time; the invention effectively solves the problems of many manual operations and difficulty in moving and fine tuning of the traditional movable winch, improves the performance, improves the production efficiency, ensures the accurate centering of the steel wire rope and the duct, ensures the efficient and stable traction of the steel strand, is suitable for the construction of prestressed engineering such as the inner containment of the nuclear power station, improves the construction quality and safety, and reduces the construction cost. The industrial technical progress is promoted.
