The invention discloses a stainless steel slab lifting appliance opening and closing mechanism, and relates to the field of steel billet clamps. The stainless steel plate blank lifting appliance opening and closing mechanism comprises a lock cylinder and a lock sleeve, a continuous waveform guide groove is formed in the outer wall of the lock cylinder, a T-shaped lock hook is integrally formed at the bottom end of the lock cylinder, a guide bolt piece is fixedly installed in the side wall of the lock sleeve, and the end of the guide bolt piece is movably inserted into the waveform guide groove. An elastic power assisting piece is installed between the top end of the lock cylinder and the lock sleeve. According to the opening and closing mechanism for the stainless steel plate blank lifting appliance, when the lock cylinder moves in the lock sleeve, the spring horizontally rotates through the plane thrust ball rotating bearing, so that the influence of horizontal torsion on the spring is eliminated, and in the unlocking process, the lock cylinder is downwards pushed in the lock sleeve through elastic potential energy of the spring, so that the lifting appliance is unlocked. The self-locking and unlocking effects of the lock cylinder are effectively improved, unlocking and falling during hoisting are avoided, automatic unlocking can be achieved after falling, and the situation that the lock cylinder is stuck and needs to be manually unlocked is avoided.
本发明公开一种不锈钢板坯吊具开闭机构,涉及钢坯夹具领域。该不锈钢板坯吊具开闭机构,包括锁芯和锁套,锁芯的外壁开设有连续的波形导向槽,锁芯的底端一体成型有T形锁钩,锁套的侧壁中固定安装有导向插销件,导向插销件的端部活动插接在波形导向槽中,锁芯的顶端与锁套之间安装有弹性助力件。该不锈钢板坯吊具开闭机构,当锁芯在锁套内部发生移动时,弹簧利用平面推力球旋转轴承进行水平旋转,从而用于消除水平扭力对弹簧的影响,在解锁过程中,利用弹簧的弹性势能将锁芯在锁套的内部向下推动,有效提升锁芯的自锁和解锁效果,避免吊运时发生脱锁坠落,在下落后能够实现自动解锁,避免出现锁芯卡死需要人力解锁的情况出现。
