该专利的扩张器同样存在扩张的距离有限的问题
Benefits of technology
本实用新型的一种法兰扩张装置，通过设置底座，为整个装置提供稳定的支撑；通过设置与底座转动连接的横梁，横梁上转动连接支撑部件和挂钩，挂钩布置于横梁的自由端，支撑部件布置于立柱与挂钩之间，同时支撑部件更靠近挂钩，在底座上放置施力部件，施力部件向支撑部件施加作用力，使得横梁绕第一转轴转动，横梁的自由端被抬起，水平板托起法兰，扩大法兰之间的距离；横梁与立柱之间利用杠杆原理，将垂直方向的作用力转化为自由端的抬升运动，降低人工操作强度，实现小力量驱动大负载的效果。本实用新型的一种法兰扩张装置，通过设置水平板插入法兰之间的间隙，无需使用撬杠，避免砸伤施工人员，同时利用施力部件作为动力源扩张法兰间距，且可根据需要扩张较大的距离，节省体力和时间。
