The invention provides an elevator car damping and buffering device which comprises a buffering and damping assembly, and the buffering and damping assembly comprises a buffering plate, a sliding seat, eight pushing rods, a supporting seat, a second damper and a second supporting spring. And the four first dampers and the four first supporting springs are symmetrically mounted on the upper surface of the buffer plate. Through cooperation of a first supporting spring and a first damper, first-time buffering and damping of the elevator car can be achieved, meanwhile, a buffering plate moves downwards under the gravity effect of the elevator car, the buffering plate pushes two second limiting plates located on the two sides to be away from each other under the combined effect of a pushing rod and a supporting plate, and therefore the elevator car can be buffered and damped; the second limiting plate can make contact with the elevator shaft, so that speed reduction and pause of the elevator car are achieved, direct falling of the elevator car is avoided, the elevator car can be directly braked through the damping and buffering device, potential energy release of the elevator car is avoided, and the stability of the elevator car during braking is enhanced.
本发明提供了一种电梯轿厢减震缓冲装置,包括缓冲减震组件,所述缓冲减震组件包括缓冲板、滑动座、八个推动杆、支撑座、第二阻尼器和第二支撑弹簧;四个所述第一阻尼器和四个所述第一支撑弹簧均对称安装于所述缓冲板的上表面。本发明通过第一支撑弹簧和第一阻尼器的配合,可以实现对电梯轿厢的第一次缓冲减震,同时在缓冲板受到电梯轿厢的重力作用下向下移动,缓冲板在推动杆和支撑板的共同作用下,推动位于两侧的两个第二限位板相互远离,进而可以使第二限位板与电梯井接触,从而实现对电梯轿厢的减速并暂停,避免电梯轿厢直接坠落,本发明的减震缓冲装置可以直接对电梯轿厢进行制动,避免电梯轿厢释放势能,增强了电梯轿厢制动时的稳定性。
