The elevator shaft protection device comprises two symmetrically-arranged derricks, protection mechanisms are installed on the two derricks correspondingly, a blocking assembly and two cushion bags are installed between the opposite surfaces of the two protection mechanisms correspondingly, and each protection mechanism comprises a distance adjusting piece installed in the corresponding derrick. The peripheral side face of the distance adjusting piece is in transmission connection with two symmetrically-arranged clamping arms with the distance adjustable, a suspension arm is slidably installed between the two clamping arms, self-compensation claw clamp assemblies are installed at the ends of the two clamping arms correspondingly, a telescopic winding roller is rotationally connected between the opposite surfaces of the two clamping arms, and the telescopic winding roller is connected with a blocking assembly. T-shaped lifting rods are fixedly mounted on the bottom surfaces of the lifting arms, and lifting frames are slidably connected to the peripheral side surfaces of the T-shaped lifting rods. Self-compensation of the loosening amount of the clamp can be achieved, and by means of the compensation function, the fixing stability and fixing strength of the protection device on the inner wall of a well are effectively improved.

    本发明公开了一种电梯井防护装置及防护方法,包括两个对称设置的井架,两个井架上均安装有防护机构,两个防护机构的相对表面之间分别安装有拦阻组件和两个垫囊,防护机构包括安装于井架内的调距件,调距件的周侧面传动连接有两个对称设置且间距可调的夹臂,两个夹臂之间滑动安装有吊臂,两个夹臂的端部均安装有自补偿爪钳组件,两个夹臂的相对表面之间转动连接有伸缩卷辊,伸缩卷辊与拦阻组件连接,吊臂的底面固定安装有T形吊杆,T形吊杆的周侧面滑动连接有吊架。本发明能够实现对夹钳松动量的自补偿,通过上述补偿功能的实现,从而有效提高防护装置在井道内壁的固定稳度及固定强度。
