Abstract

The embodiment of the invention provides a pin shaft monitoring method and equipment for tower crane jacking operation. The method comprises the following steps of acquiring a tower crane balancing state according to tower crane information; and if the tower crane balance is completed, a pin shaft electronic lock is unlocked, the position of the pin shaft is detected, and if the position of the pin shaft is in an open state, a jacking oil cylinder is controlled to conduct jacking operation. According to the pin shaft monitoring method and equipment for the tower crane jacking operation, on thepremise that manual experience is not relied on, it can be guaranteed that the tower crane carries out safe balancing and jacking operation, major potential safety hazards are eradicated, and the reliability of the tower crane jacking operation is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of tower cranes, and in particular to a pin shaft monitoring method and equipment for tower crane jacking operations. Background technique [0002] During the jacking process of the tower crane, if the pin shaft between the lower support and the standard section is directly opened before the tower crane is balanced, or the jacking is started before the pin shaft is opened, major accidents may occur. security incident. At present, there are no mature measures or technical means to prevent such problems. The safety action of the lower support and the standard internode connecting pin mainly depends on the experience and professionalism of the operator, and the safety guarantee of the jacking operation is more dependent on man-made Factors, its reliability is low. Therefore, developing a pin shaft monitoring method for tower crane jacking operations, which can effectively overcome th...
