Title:
CONTROL METHOD FOR STEEL JACKING PLATFORM CAPABLE OF ACHIEVING OVERALL JACKING AND PARTIAL JACKING
Document Type and Number:
WIPO Patent Application WO/2019/011318
Kind Code:
A1
Abstract:
A control method for a steel jacking platform capable of achieving overall jacking and partial jacking, comprising: firstly, closing N main power supply switches, N control transformer power supply switches and N control circuit switches; during startup, pressing down corresponding startup switches on electromagnetic starters connected to the control circuit switches, powering on and pulling in coils of corresponding main contactors, closing and self-locking normally-opened auxiliary heads of the main contactors, closing main contact heads of the main contactors, and powering on and starting up corresponding motors to run continuously; and when stopping, pressing down stop switches on the electromagnetic starters connected to the control circuit switches, powering off and disconnecting coils of the corresponding main contactors, separating and disconnecting the self-locking contact heads of the main contactors, separating and disconnecting the main contact heads of the main contactors, and powering off the corresponding motors to stop running. The steel platform may be subjected to overall jacking and partial jacking, precise control in the use process of the steel platform is greatly improved, the requirements for steel platform jacking at different positions are met, without affecting the overall progress of construction.
