The invention relates to the technical field of machinery, and discloses a speed-limiting locking mechanism for a mechanical cargo boom, the speed-limiting locking mechanism comprises a coiling device for increasing load bearing, the coiling device comprises a coiling wheel, and the surface of the coiling wheel is fixedly connected with a friction wheel for reducing the speed of the coiling wheel; the surface of the rear side of the friction wheel is fixedly connected with a one-way clamping wheel used for clamping the winding wheel. According to the speed-limiting locking mechanism for the mechanical cargo boom, through cooperative use of the wire winding device, the traction wire, the fixing pile, the locking device, the forward and reverse rotation adjusting device, the touch device, the bevel gear and the limiting block, the locking device is additionally arranged on the wire winding device, the stability of a heavy object in the hovering and descending process is guaranteed, the heavy object is prevented from being out of control during descending, and the service life of the heavy object is prolonged. The safety of the device is improved, in the descending process, gravitational potential energy of a heavy object is utilized for descending, the descending speed is controlled through the locking device, and the energy-saving and environment-friendly effects are better achieved.

    本发明涉及机械技术领域,且公开了一种用于机械起重臂的限速锁止机构,包括增加承重的卷线装置,所述卷线装置包括卷线轮,所述卷线轮的表面固定连接有用于给卷线轮降速的摩擦轮,所述摩擦轮的后侧表面固定连接有用于将卷线轮卡死的单向卡轮。该用于机械起重臂的限速锁止机构,通过卷线装置、牵引线、固定桩、锁止装置、正反转调节装置、触动装置、斜齿轮和限位块的配合使用,从而达到了对卷线装置部分增加了锁止装置,保证了重物在悬停和下降过程中的稳定性,防止其下降失失控,甚至坠落,增大了装置的安全性,且下降时利用重物自身的重力势能下降,并利用锁止装置控制下降的速度,更加的节能环保的效果。
