The invention discloses a lifting portal frame structure which comprises two portal frames arranged symmetrically, hoisting hooks for hoisting components are arranged on the portal frames, and driving modules for driving the hoisting hooks to move on the portal frames in the X-axis direction, the Z-axis direction and the Y-axis direction are further arranged on the portal frames. The portal frame is further provided with an anti-falling assembly for rapidly braking and locking the falling component within the limited distance, and the anti-falling assembly can lock rotation of the driving end of the Z-direction motor. According to the lifting portal frame structure, the mounting disc rotates along with rotation of the Z-direction motor driving shaft, when the rotating speed of the lifting portal frame structure reaches a certain speed, the clamping strips are affected by the centrifugal force effect of the mounting disc, so that the ends of the clamping strips extend out of the mounting disc and are clamped to the clamping hooks, and braking of rotation of the Z-direction motor driving shaft is achieved; and more reliable and efficient anti-falling protection can be provided in actual operation, so that the safe operation of hoisting operation is ensured.
本发明公开了一种升降龙门架结构,该升降龙门架结构包括呈对称设置的两个龙门架,龙门架上设置有对构件进行吊装的吊装挂钩,龙门架上还设置有驱动吊装挂钩在龙门架上沿X轴向、Z轴向和Y轴向进行运动的驱动模组,龙门架上还设置有在限定距离内快速制动锁定坠落构件的防坠组件,防坠组件可对Z向电机驱动端的转动进行锁定。本发明提供的升降龙门架结构通过安装盘随着Z向电机驱动轴的转动而转动,当其转速达到一定速度时,卡条受到安装盘的离心力效果影响可使其端部伸出安装盘并卡接在卡勾上,以实现对Z向电机驱动轴转动的制动,能够在实际操作中提供更加可靠和高效的防坠落保护,以确保吊装作业的安全进行。
