The invention discloses a buffering protection device for an elevator car. Aiming at the problem that the amplitude of a device cannot be rapidly attenuated after buffering, the following scheme is provided. The protection device comprises a fixing frame, wherein folded plates are fixed to the two sides of the outer wall of the top of the fixing frame through bolts, a first rubber damping block isbonded to the inner wall of the bottom of the fixing frame, a plurality of base plates are fixedly bonded close to the center of the outer wall of the top of the first rubber damping block, fixing cylinders are fixed to the outer walls of the tops of the base plates through bolts, piston rods are inserted into the inner walls of the tops of the fixing cylinders, the circumferential outer walls ofthe fixing cylinders are sleeved with supporting plates, and damping springs are welded to the outer walls of the tops of the supporting plates. According to the protection device, when an elevator falls down and is in contact with the device, the first rubber damping block is compressed, under the obstruction of the folded plates, the pressure by elevator falling is concentrated inwards, and therefore the device can fully buffer the pressure and protect personnel in the elevator.

    本发明公开了一种电梯轿厢用缓冲保护装置,针对缓冲后装置振幅不能迅速衰减的问题,现提出以下方案,包括固定架,所述固定架顶部外壁的两侧均通过螺栓固定有折板,所述固定架的底部内壁上粘接有第一橡皮减震块,所述第一橡皮减震块的顶部外壁靠近中心的位置粘接有固定有多个底盘,所述底盘的顶部外壁上通过螺栓固定有固定筒,所述固定筒的顶部内壁上插接有活塞杆,所述固定筒的圆周外壁上套接有托板,所述托板的顶部外壁上焊接有减震弹簧。本发明使得电梯坠落与装置接触时,第一橡皮减震块压缩,在折板的阻碍下,电梯坠落的压力向内集中,从而使得装置可以充分将压力进行缓冲,对电梯内部的人员进行保护。
