The invention relates to the technical field of building construction equipment, and discloses an automatic locking control lifting pulley for building construction. The automatic locking control lifting pulley for building construction comprises a shell, a control shaft is movably connected to the interior of the shell, a brake is fixedly connected to the outer side of the control shaft, a moving rope is movably connected to the interior of the shell, a rotating wheel is movably connected to the interior of the shell, and electromagnets which are evenly distributed are fixedly connected to the interior of the rotating wheel. According to the automatic locking control lifting pulley for building construction, through mutual cooperation of the electromagnets and permanent magnets, when the electromagnets are powered on, the electromagnets generate a magnetic field, the electromagnets and the permanent magnets attract each other due to the fact that the magnetism of the opposite faces is opposite, a limiting block is driven to overcome the elastic force effect of a second spring to move, the limiting block and a groove in the inner side of the rotating wheel are matched, the rotating wheel rotates in one direction, when the rotating wheel rotates reversely, the limiting block limits movement of the rotating wheel, the one-way moving function of a product is achieved, the safety of a user during use is ensured, and falling of personnel is prevented.

    本发明涉及建筑施工设备技术领域,且公开了一种建筑施工用自动控制锁合的升降滑轮,包括壳体,所述壳体内部活动连接有控制轴,控制轴外侧固定连接有制动器,壳体内部活动连接有移动绳,壳体内部活动连接有旋转轮,旋转轮内部固定连接有均匀分布的电磁铁。该建筑施工用自动控制锁合的升降滑轮,通过电磁铁与永磁体的相互配合,当电磁铁通电时,电磁铁产生磁场,电磁铁与永磁体因相对面磁性相反而相互吸引,带动限位块克服弹簧二弹力作用移动,使得限位块与旋转轮内侧的凹槽相互配合,使得旋转轮进行单向旋转,当旋转轮反转时,限位块限制旋转轮的移动,实现了产品的单向移动功能,保证了用户使用时的安全性,防止了人员的坠落。
