AI Technical Summary
Technical Problem
The existing elevator buffer compression and rebound performance test bench has a slow unloading speed, which leads to inaccurate measurement of the rebound performance of polyurethane buffers and creates additional constraint resistance.
Method used
The design employs a spring and a limiting plate. By using the limiting plate to release the fixing of the pressure head, the spring can instantly release its elastic potential energy, thereby achieving rapid unloading of the pressure head and avoiding additional resistance to the rebound of the buffer.
Benefits of technology
It improves the accuracy of buffer rebound speed and height data, ensuring the precision of test results and meeting the modern elevator industry's demand for high-precision testing equipment.

Abstract
本发明涉及电梯缓冲器测试技术领域，具体涉及电梯缓冲器压缩回弹性能测试台，包括机架、安装座、升降梁、压头、弹簧和限位板，安装座设于机架上，用于安装待测缓冲器，压头能够在升降梁的带动下向下抵压安装座的待测缓冲器，压头下降至目标高度后，限位板能够横向滑动并解除对压头的固定，以使压头在弹簧弹性力的作用下升起，为待测缓冲器的回弹让出空间。本发明提供的电梯缓冲器压缩回弹性能测试台，通过弹簧与限位板实现了压头的快速卸载，在限位板解除对压头的固定后，弹簧能够瞬间释放弹性势能，使压头迅速升起，快速为缓冲器的回弹让出空间，使得缓冲器能够按照自身的弹性性能自由回弹，测得的回弹速度和回弹高度数据更加准确。
