The invention provides a bridge crane lifting rope swing angle detection device based on an electromagnetic induction principle. The bridge crane lifting rope swing angle detection device comprises a box body, a first Helmholtz coil, a second Helmholtz coil, a first light swing part, a second light swing part, a first fixing part, a second fixing part, a first coil, a second coil, an alternating current power supply and a signal acquisition and processing device, wherein the first Helmholtz coil, the second Helmholtz coil, the first light swing part, the second light swing part, the first fixing part, the second fixing part, the first coil, the second coil, the alternating current power supply and the signal acquisition and processing device are contained in the box body. The first Helmholtz coil and the second Helmholtz coil are respectively connected with the alternating current power supply so as to generate alternating magnetic fields in the first Helmholtz coil and the second Helmholtz coil; and the first coil and the second coil are connected with the signal acquisition and processing device, and the signal acquisition and processing device is used for receiving induced electromotive force generated by the first coil and the second coil and calculating the rotation angle of the first coil and the rotation angle of the second coil according to the electromagnetic induction principle, so that the swing angle of a bridge crane lifting rope is calculated. A non-contact angle measurement manner is adopted, measurement errors caused by mechanical abrasion or the environment can be eliminated, and therefore high precision is achieved.
