A mechanism for erecting a herringbone spar
By designing an auxiliary mechanism that drives the triangular plate to swing using a hydraulic rod, the problems of complex structure and high manpower consumption during the erection of the A-frame derrick were solved. This enabled efficient and stable erection and angle adjustment of the A-frame derrick, improving the operational reliability and safety of the equipment.

AI Technical Summary
The existing A-frame erection device has a complex structure, is cumbersome to operate, consumes a lot of manpower, has low work efficiency, and is prone to deformation and damage during operation, thus failing to meet the requirements for equipment stability and safety.
An auxiliary mechanism including a base plate, an A-frame, a hydraulic rod, and a triangular plate was designed. The triangular plate is driven to swing by the hydraulic rod, and the linkage rod realizes the erection or tilting of the A-frame. Combined with the sliding engagement of the slide groove and the connecting seat, a stable mechanical support structure is formed, which improves the structural strength and resistance to deformation.
It enables efficient erection and angle adjustment of the A-frame derrick, improving work efficiency, ensuring equipment stability and safety, and preventing deformation and damage.
