Description

Technical Field

[0001] The present invention relates to the field of cranes, and particularly relates to a pulley installation simulation device and a method for determining the installation position of a wire break protection support. Background Art

[0002] The equalizing pulley support at the top of the trapezoidal frame body of a quay container crane (hereinafter referred to as "quayside crane") is prefabricated into a component, and then the heavy plate and the pulley shaft hole are machined integrally.

[0003] Due to certain errors in the installation of the equalizing pulley support component, there will be a spatial angle deviation when the equalizing pulley is installed, resulting in a change in the rope exit direction of the luffing wire rope. Therefore, when the trapezoidal frame body structure is fabricated, it is impossible to accurately position and install the wire break protection support. The wire break protection support can only be positioned and welded on-site according to the actual running direction of the wire rope after the luffing wire rope is threaded.

[0004] This work often needs to be completed after the overall assembly of the quayside crane, which is likely to damage the paint of the trapezoidal frame body structure. At the same time, this work is a hot work at high altitude, posing certain safety hazards. Summary of the Invention
