The invention discloses hoisting equipment for a steel structure. The hoisting equipment comprises a pre-warning mechanism and a clamping mechanism, wherein the pre-warning mechanism comprises a horn,a contact, a connecting plate, a first hook, a second hook, a connecting rod and a spring, a supporting plate is fixedly installed on the first hook, the contact is correspondingly and fixedly installed on the lower surface of the supporting plate and the bottom end of the interior of a supporting frame, a power supply and a loudspeaker are fixedly installed on a side plate of the supporting frame, and the contact, the power supply and the loudspeaker are connected with electric wires. A second rotating shaft is rotationally connected with the supporting frame, a pointer is fixedly installedon the second rotating shaft, and a dial plate is fixedly installed on the supporting frame corresponding to the pointer. When hoisting is too heavy, the lower surface of the supporting plate makes contact with the corresponding contact at the bottom end of the interior of the supporting frame, so that the loudspeaker is powered on to make a sound, an operator is reminded that the number of the hoisted steel structures is too large, and casualties and device damage caused by accidents in the hoisting process are avoided.
一种钢结构用吊装设备,包括预报警机构和夹持机构,所述预报警机构包括喇叭、触点、连接板、第一挂钩、第二挂钩、连接杆和弹簧,所述第一挂钩上固定安装有支撑板,所述支撑板的下表面和支撑框的内部底端相对应的固定安装有触点,所述支撑框的侧板上固定安装有电源和喇叭,所述触点和电源和喇叭连接有电线。所述第二转动轴与支撑框转动连接,所述第二转动轴上固定安装有指针,与指针相对应的在支撑框上固定安装有表盘。当吊装过重是,支撑板的下表面和支撑框的内部底端相对应的触点接触,从而使得喇叭通电响起,从而提醒操作者吊装钢结构数量超重,从而避免吊装过程中发生意外,导致人员伤亡和装置的损坏。
