The invention relates to the technical field of wind power equipment, in particular to energy-saving auxiliary lifting beam equipment for lifting a wind power jacket, which comprises an upper lifting beam, a lower lifting beam and a middle beam, a movable outer seat is slidably connected outside the middle beam, and negative feedback damping mechanisms are symmetrically arranged outside the movable outer seat. The negative feedback damping mechanism comprises a damping cylinder arranged outside the movable outer seat, and a piston rod is in threaded connection with the outside of the damping cylinder. When the lower hanging beam and the middle beam shake, the negative feedback damping mechanism prevents the lower hanging beam and the middle beam from shaking and prevents the piston rod from moving, and the piston rod moves and rotates under the action of the threaded pipe to drive the piston to move along with the piston rod; when the lower hanging beam and the middle beam shake suddenly or violently clockwise, the moving and rotating speed of the piston rod is increased, the moving distance of the sliding block to the edge of the piston is increased, the flux of the damping groove is decreased, the blocking force of the damping liquid is increased, and therefore the lower hanging beam and the middle beam are prevented from shaking and tend to be stable.
本发明涉及风电设备技术领域,尤其涉及一种风电导管架吊装用节能辅助吊梁设备,包括上吊梁、下吊梁与中间梁,中间梁外部滑动连接有活动外座,活动外座外部对称设置有负反馈阻尼机构,负反馈阻尼机构包括设置活动外座外部的阻尼筒,阻尼筒外部螺纹连接有活塞杆,本发明中,在下吊梁与中间梁出现晃动时,通过负反馈阻尼机构阻碍其晃动,活塞杆移动,通过螺纹管作用,活塞杆移动并转动,带动活塞同活塞杆运动,当下吊梁与中间梁出现较为突然或者剧烈的顺时针晃动时,活塞杆移动与转动速度变快,滑块向活塞边缘处移动的距离变大,进而阻尼槽的通量变小,进而阻尼液的阻碍力就变大,进而阻碍下吊梁与中间梁的晃动,使其更加趋于稳定。
