The invention provides a wind-proof tower crane for building, and relates to the field of cranes. The wind-proof tower crane comprises a machine body, a two arm is arranged on the machine body, and aninstallation plate is arranged at the bottom of the tower arm. According to the wind-proof tower crane, when the position of a counterweight box needs to be adjusted, a first servo motor can be started to drive the rotation of a threaded rod, thus a nut is driven to move on the threaded rod, the position of a U-shaped plate is conveniently adjusted, according to the external wind force, a secondservo motor can be started to drive the rotation of a rotating roller, thus the height of the counterweight box is conveniently adjusted, a third servo motor is started to drive the rotation of a screw rod, thus the movement of a screw rod nut is driven, and by arranging the screw rod nut, a rope is conveniently limited.

    本发明提供一种建筑用防风塔式起重机,涉及起重机领域,包括机体,机体上设置有塔臂,塔臂的底部设置有安装板。本发明中,当需要对配重箱的位置进行调整时,可以通过启动第一伺服电机带动螺纹杆的转动,从而带动螺母在螺纹杆上移动,从而便于对U型板位置进行调整,并且根据外界风力,可以通过启动第二伺服电机带动转辊的转动,从而便于对配重箱的高度进行调整,通过启动第三伺服电机带动丝杆的转动,从而带动丝杆螺母的移动,通过设置丝杆螺母,便于对绳索进行限位。
