The invention relates to the technical field of braking equipment, and discloses an anti-falling safety device for a construction elevator. Sliding grooves are uniformly formed in the outer ring of a conical hub, friction blocks are movably connected into the sliding grooves in a sleeved mode, a centrifugal rotating block seat is fixedly connected to one side, close to a shell, of a gear through a shaft, a strip-shaped magnet is fixedly mounted in the middle of the centrifugal rotating block seat, electromagnets are symmetrically and fixedly mounted at the positions, located at the top and the bottom of the strip-shaped magnet, in the centrifugal rotating block seat, rotating cavities are vertically and symmetrically formed in the positions, located at the end part of a centrifugal block, in the centrifugal rotating block seat, rotating rods are movably mounted in the rotating cavities, magnet sets are respectively and fixedly mounted at the positions, corresponding to conductive heads, of the top and the bottom of the inner wall of the shell, and short rods at the bottoms of the rotating rods are clamped in clamping grooves. According to the anti-falling safety device, the strip-shaped magnet is arranged to be matched with the centrifugal block to work, an electromagnet structure for limiting the centrifugal block is further arranged, the structure and the installation of a friction block are adjusted, the braking effect and precision of the anti-falling safety device can be improved, and the safety is guaranteed.

    本发明涉及制动设备技术领域,且公开了一种施工电梯用防坠安全器,锥毂的外圈均匀开设有滑槽,滑槽内部活动套接有摩擦块,齿轮靠近外壳的一侧通过轴固定连接有离心转块座,离心转块座的中部固定安装有条形磁铁,离心转块座内部位于条形磁铁的顶部和底对称固定安装有电磁铁,离心转块座内部位于离心块端部上下对称开设有转动腔,转动腔内部活动安装有转杆,外壳内壁位顶部和底部位于导电头对应的位置分别固定安装有磁铁组,转杆的底部短杆卡接在卡槽内,通过设置条形磁铁配合离心块工作,并且还设置有限制离心块的电磁铁结构,同时将摩擦块的结构和安装进行调整提高了防坠安全器的制动效果和精度,保证了安全性。
