A lifting frame relates to the technical field of workpiece movement and comprises a frame-shaped machine frame, air cylinders arranged on the two sides of the frame-shaped machine frame, a movable frame driven by the air cylinders to lift and more than one lifting auxiliary mechanism. The lifting auxiliary mechanism comprises lower pulleys fixed to the two sides of the bottom of the frame-shaped rack, upper pulleys arranged on the two sides of the top of the frame-shaped rack, and two ropes wound around the lower pulleys and the upper pulleys. One rope connected to one side of the movable frame sequentially bypasses the lower pulley on one side, the upper pulley on one side and the upper pulley on the other side and then is connected to the other side of the movable frame; and the other rope connected to the other side of the movable frame sequentially bypasses the lower pulley on the other side, the upper pulley on the other side and the upper pulley on one side and then is connected to one side of the movable frame. Compared with the prior art, the lifting mechanism has the advantage that the cylinders on the two sides are synchronously jacked during lifting.

    一种升降架,涉及工件移动技术领域,包括框形机架、设置在框型机架两侧的气缸、由气缸带动升降的活动架,设置一套以上的升降辅助机构,升降辅助机构包括固定在框形机架底部两侧的下滑轮、设置在框形机架顶部两侧的上滑轮、绕在下滑轮和上滑轮上的两根绳,其中一根连接在活动架其中一侧的绳依序绕过其中一侧的下滑轮、其中一侧的上滑轮、另一侧的上滑轮后连接在活动架另一侧上,另一根连接在活动架另一侧的绳依序绕过另一侧的下滑轮、另一侧的上滑轮、其中一侧上滑轮后连接在活动架的其中一侧。本发明与已有技术相比,具有升降时两侧气缸顶升同步的优点。
