The invention discloses a central safety protection type connecting device for a building hoist. The central safety protection type connecting device for the building hoist comprises a bottom installation base plate, and is used for connecting a drive motor and a steel wire winding wheel in hoisting equipment, so that a maximum winding strength protection function, a hoisting strength reduction function and an emergency braking function can be realized. In addition, the device is provided with a ring array spiral spring elastic compression type maximum rotation acting force control mechanism,so that a maximum rotation capacity between rotating members can be effectively controlled by utilizing spiral springs arranged in an ring array way, the maximum hoisting strength is further controlled, and the occurrence of serious accidents caused by hoisting overload is prevented; in addition, the device is provided with an electromagnetic permanent magnet telescopic friction type emergency braking mechanism, so that a function on emergently braking a rotating state is realized by utilizing an electromagnetic principle and a principle that same magnetic poles mutually repulse, and oppositemagnetic poles attract; and in addition, the device is provided with a gear set engagement rotating force decreasing type control mechanism, so that a strength reduction function is realized by utilizing a gear difference principle.

    本发明公开了一种建筑起吊器用中部安全防护式连接装置,包括底部安装基板。本发明用于连接起吊设备中驱动电机和钢丝卷扬轮之间的连接,能够起到最大卷扬力度的保护功能、降低起吊力度功能和紧急制动的功能,而且,该装置具有环形阵列螺旋弹簧弹性压缩式最大旋转作用力控制机构,能够利用环形阵列设置的螺旋弹簧,有效控制旋转部件之间的最大旋转能力,进而控制最大起吊力度,防止起吊超载而导致的严重事故的发生,此外,该装置具有电磁永磁体伸缩摩擦式紧急制动机构,利用电磁原理和磁极间的同性相斥异性相吸原理,实现对旋转状态的紧急制动功能,另外,该装置具有齿轮组啮合旋转力递减式控制机构,利用齿轮差原理,实现降低力度功能。
