The invention relates to a pier beam limiting device capable of preventing beam falling, which belongs to the technical field of bridge engineering and is suspended and fixed on the lower side of a beam body and used for limiting displacement of an upper cover beam of a buffer pier column. A damper in the limiting device comprises a compression elastic unit and a tension-bearing elastic unit which are used in cooperation, the compression elastic unit comprises a first inner sleeve and a tension-bearing spring placed in the first inner sleeve, one end of the tension-bearing spring is fixedly connected with the inner wall of the top of the first inner sleeve, and the other end of the tension-bearing spring is fixedly connected with a piston sliding rod. The tension-bearing elastic unit comprises a second inner sleeve and a pressure-bearing spring placed in the second inner sleeve, the piston sliding rod penetrates through the second inner sleeve, the free end of the piston sliding rod is fixedly connected with the end of the tension-bearing spring, the piston sliding rod is sleeved with the pressure-bearing spring, and one end of the pressure-bearing spring is fixed to the inner wall, close to one side of the first inner sleeve, of the second inner sleeve; one end of the pressure-bearing spring close to the cover beam abuts against the inner wall of the second inner sleeve; the pier beam limiting device can flexibly restrain displacement of the pier beam and effectively prevent beam falling.
本发明涉及一种防落梁的墩梁限位装置，属于桥梁工程技术领域，限位装置悬挂固定在梁体的下侧，用于限制缓冲墩柱上盖梁的位移；限位装置中阻尼器包括配合使用的压缩弹性单元与承拉弹性单元，压缩弹性单元包括第一内套筒和放置在第一内套筒内的承拉弹簧，承拉弹簧一端与第一内套筒顶部内壁固定连接，另一端与活塞滑动杆固定连接；承拉弹性单元包括第二内套筒和放置在第二内套筒内的承压弹簧，活塞滑动杆贯穿第二内套筒后自由端与承拉弹簧端部固定连接，承压弹簧套装在活塞滑动杆上且一端固定在靠近第一内套筒一侧的第二内套筒内壁上，承压弹簧靠近盖梁一端与第二内套筒内壁相抵；该墩梁限位装置能够灵活约束墩梁位移且能够有效防止落梁。
