The invention discloses a screw drive manual brake release device for an elevator main machine. The screw drive manual brake release device comprises a brake release device shell, a brake shoe assembly, a middleware, a thrust ball bearing assembly and a brake release wrench. A cylindrical groove matched with the middleware and the thrust ball bearing assembly is formed in the middle of the brake releasing device shell. The thrust ball bearing assembly is installed on the middle piece and then embedded into the cylindrical groove. One end of the middle piece is connected with the brake shoe assembly, and the other end of the middle piece is connected with a short handle of the brake release wrench. The brake shoe lifting device is high in integration level and small in size, the brake shoe is lifted in a spiral lifting mode, and the force needing to be applied during operation is greatly reduced by amplifying torque through the connecting rod. The spiral lifting mode and the mode of amplifying the torque through the connecting rod are adopted, the length of the connecting rod can be greatly reduced, the needed operation space is smaller, and space optimization of hoistway arrangement is facilitated.
本发明公开了一种用于电梯主机的螺杆传动手动松闸装置,包括松闸装置壳体、制动靴装配、中间件、推力球轴承组件和松闸扳手;所述松闸装置壳体的中部开设与所述中间件、推力球轴承组件相适配的圆柱槽;所述推力球轴承组件安装于所述中间件上后嵌入所述圆柱槽内;所述中间件的一端与所述制动靴装配连接,所述中间件的另一端与所述松闸扳手的短柄连接。本发明集成度较高,体积小,采用螺旋提拉的形式提拉制动靴,并利用连杆放大力矩大大降低操作时所需施加的力。本发明采用螺旋提拉的形式以及利用连杆放大力矩的形式,可以大大减少连杆的长度,需要的操作空间更小,有利于井道布置的空间优化。
