The invention relates to the technical field of building equipment, and discloses a safety braking device of a construction elevator. The safety braking device of the construction elevator comprises a shell, wherein a friction ring is fixedly installed in the cone part of the shell; an inner ring of the friction ring is movably connected with a cone hub in a sleeved mode; cone drums are evenly and fixedly installed on the inner side of the cone hub; a centrifugal rotating block seat is fixedly connected to the side, close to the shell, of a gear through a shaft; centrifugal blocks are symmetrically and movably installed on an outer ring of the centrifugal rotating block seat; annular magnets located between the centrifugal blocks and the conical drums are correspondingly and fixedly installed on the inner bottom wall of the conical hub and the inner wall of the shell correspondingly; an annular groove is formed in the conical inner part of the conical hub; one end of the annular groove communicates with an inner ring of the conical hub; strip-shaped magnets are fixedly installed on the sides, close to the centrifugal rotating block seat, of the centrifugal blocks; two iron cores are symmetrically and fixedly installed on the centrifugal rotating block seat; and the electromagnetic effect is achieved through rotation of the centrifugal rotating block seat and the iron cores wound with wires to replace springs, so that the safety is higher.

    本发明涉及建筑设备技术领域,且公开了一种施工电梯安全制动装置,包括外壳,所述外壳锥体部位的内部固定安装有摩擦环,所述摩擦环的内圈活动套接有锥毂,所述锥毂的内侧均匀固定安装有锥鼓,所述齿轮靠近外壳的一侧通过轴固定连接有离心转块座,所述离心转块座的外圈对称活动安装有离心块,所述锥毂的内底壁与外壳的内壁分别对应固定安装有位于离心块与锥鼓之间的环形磁铁,所述锥毂锥状内部开设有环槽且环槽的一端连通到锥毂内圈,所述离心块靠近离心转块座一侧的固定安装有条形磁铁,所述离心转块座的呈对称固定安装有两根铁芯,通过离心转块座的转动和缠绕导线的铁芯实现电磁作用代替弹簧,安全性更高。
