The invention discloses a loading-unloading lift capable of realizing overweight automatic locking. The lift comprises a base, wherein a first slide block cavity with an upward opening is disposed onthe upper end face of the base; a first slide block can be disposed in a vertical sliding manner inside the first slide block cavity; a first spring is fixedly connected between the first slide blockand the inner wall of the first slide block cavity; a lifting device is disposed above the base; a locking device is disposed above the base; and an unlocking resetting device is disposed in the locking device. The lift disclosed by the invention has the beneficial effects that the structure is simple; in a lifting operation of materials, the lifting device can be locked automatically in case of an overweight situation, so that a possibility in accident occurrence during the lifting operation under the overweight situation is avoided; locking can be relieved automatically when an overweight part is removed, the locking device can be reset, and judgment and locking in case of a next overweight state are not influenced; and safety and reliability of the material lifting operation are significantly enhanced.

    本发明公开的一种超重自动锁定的上下料升降机,包括底座,所述底座上端面设有开口向上的第一滑块腔,所述第一滑块腔内可上下滑动的设有第一滑块,所述第一滑块与所述第一滑块腔内壁之间固定连接有第一弹簧,所述底座上方设有升降装置,所述底座上方设有锁定装置,所述锁定装置内设有解锁复位装置,本发明结构简单,在对物料进行升降作业时,出现超重情况则自动将升降装置锁定,避免超重时升降作业出现意外的可能性,且在取下超重部分后可自动地解除锁定,使得锁定装置复位,不影响下一次超重状态的判断和锁定,显著地增大了物料升降作业的安全可靠性。
