The invention relates to a static load test bench and a test method. The static load test bench comprises a main frame body, a hanging adjusting device and a power loading device. The hanging adjusting device comprises an upper guide wheel set and a lower guide wheel set, and the upper guide wheel set is arranged on the upper portion of the main frame body and can move in the first direction. The lower guide wheel set is arranged on the lower portion of the main frame body and can move in the first direction. By simulating the bearing stress condition of the to-be-tested traction machine under the actual operation working condition, safety parameters such as strength, stress and deformation of a mechanical structure of the to-be-tested traction machine during bearing stress are tested, guidance parameters are provided for the design of the mechanical structure of the traction machine, and it is guaranteed that the mechanical safety performance of the traction machine meets the standard requirement. The positions of the upper guide wheel set and the lower guide wheel set are adjusted in the first direction, the hanging mode of the traction rope is changed, the installation modes of vertical pull-down, pull-up, wrap angle pull-down and the like of the traction wheel of the traction machine are met, the static load test device is suitable for static load tests of different traction machines, universality is high, and meanwhile cost is saved.
本发明涉及一种静载试验台及试验方法。静载试验台包括包括主架体、吊挂调整装置及动力加载装置。吊挂调整装置包括上导轮组及下导轮组,上导轮组设于主架体的上部,并能够沿第一方向运动。下导轮组设于主架体的下部,并能够沿第一方向运动。通过模拟待测曳引机在实际运行工况下的承载受力情况,测试出待测曳引机在承载受力时机械结构的强度、应力、形变等安全参数,为曳引机机械结构设计提供指导参数,保证曳引机的机械安全性能符合标准要求。通过沿第一方向调节上导轮组及下导轮组的位置,改变曳引绳的吊挂方式,满足曳引机的曳引轮垂直下拉、上拉、包角下拉等安装方式,适用不同曳引机的静载试验,通用性强,同时节约成本。
