The invention discloses an electric single-beam crane with an early warning function, and relates to the technical field of electric single-beam cranes. The electric single beam body is connected with a crane body in a sliding manner; the bottom end of the crane body is fixedly connected with a steel wire rope; the bottom end of the steel wire rope is fixedly connected with a rotating disc; the bottom end of the rotating disc is rotationally connected with a lifting hook; the lifting hook is connected with a connecting hook; a pressing plate is slidably connected into the lifting hook. The connecting hook is installed on the lifting hook, the connecting hook is prevented from being separated from the interior of the lifting hook in the process, a first connecting rod, a seesaw and a second connecting rod are connected in a hinged mode and can rotate, and after the connecting hook moves to a designated position, the connecting hook moves upwards, and a pressing plate can be reset through elasticity of a reset spring; and at the moment, the connecting hook can be separated from the interior of the lifting hook from the position above the early warning lock rod, and the situation that the connecting hook is easily separated from the lifting hook in the working process can be avoided through the early warning lock rod.

    本发明公开了一种具有预警功能的电动单梁起重机,涉及电动单梁起重机技术领域,包括电动单梁体;所述电动单梁体上滑动连接有起重机体;所述起重机体的底端固接有钢丝绳;所述钢丝绳的底端固接有旋转盘;所述旋转盘的底端转动连接有吊钩;所述吊钩上连接有连接钩;所述吊钩的内部滑动连接有压板;通过连接钩安装至吊钩上,避免连接钩在过程中脱离吊钩的内部,一号连接杆、跷板与二号连接杆的连接是铰接的,可以转动的,当连接钩移动至指定位置后,将连接钩向上移动通过复位弹簧的弹性会使压板复位,从而使预警锁杆向下滑动复位,此时连接钩可以从预警锁杆上方脱离吊钩的内部,通过预警锁杆可以避免工作过程中连接钩轻易脱离吊钩上的情况。
