The invention discloses an unhooking device with a protection system and a test method thereof. The device comprises the unhooking device and a safety protection system. The unhooking device is composed of a chain block, a chain fall, a hook, a lock catch, a ground anchor ring, a force sensor and a traction steel wire rope, and the safety protection system is composed of a U-shaped clamp, a lock catch and an unhooking steel wire rope. During the test, the chain block is connected with the ground anchor and the traction steel wire rope, and the chain block is utilized to apply excitation to a to-be-tested structure by contracting the chain fall. After a preset load is reached, the U-shaped clamp and the unhooking steel wire rope are connected with two ends of the ground anchor and the traction steel wire rope. The chain fall is loosened so that the unhooking steel wire rope is tensioned to play a limiting role of the unhooking device. The unhooking steel wire rope is sheared off by using a steel wire rope shear, and pulse excitation load can be applied to the structure. The chain fall is loosened before shearing, the traction steel wire rope is limited by the chain block when flyingout, oscillation attenuation of equipment in a controllable range is achieved, and safety of testing personnel is guaranteed on the basis that testing precision is guaranteed.

本发明公开一种含保护系统的脱钩装置及其试验方法，装置包括脱钩装置及安全保护系统，脱钩装置由手拉葫芦、倒链、挂钩、锁扣、地锚环、力传感器和牵引钢丝绳组成，安全保护系统由U型卡、锁扣和脱钩钢丝绳组成。试验时，先将手拉葫芦与地锚和牵引钢丝绳相连，通过收缩倒链，使用手拉葫芦为待测结构施加激励。达到预定荷载后，通过U型卡和脱钩钢丝绳与地锚和牵引钢丝绳两端相连。放松倒链，使脱钩钢丝绳张紧，发挥脱钩装置限位作用。使用钢丝绳剪剪断脱钩钢丝绳，即可对结构施加脉冲激振荷载。由于剪断前放松倒链，使得牵引钢丝绳飞出时，由手拉葫芦限制，设备在可控范围振荡衰减，在保证测试精度的基础上，确保测试人员的安全。
