The invention discloses an automatic rope clamping device based on tension detection, which belongs to the field of oil-gas field development and comprises a clamping device, a blowout prevention unit, a transmission unit, an anti-falling device, a tension monitoring device, a rope, a winch and a hydraulic system. When the rope is broken from the winch and the tension of the tension monitoring device is reduced to zero, a signal is transmitted to the hydraulic system, the hydraulic system instantly starts the hydraulic pump to press, and hydraulic oil enters the clamping device to push the clamping block to close and clamp the rope, so that the instrument is prevented from falling into a well. When the rope is clamped, an operator can easily close a testing valve, a safety valve and other valves on an anti-falling device, a blowout prevention unit or a Christmas tree, and accidents are prevented. By using the clamping device, the clamping device can make an instant response within 1-2 seconds, clamp a broken
