The double-line breakage detection device comprises a fixing device 10, at least two detection devices 20 arranged on the fixing device 10, and at least two wire passing devices 30 arranged on the fixing device 10. It is conceivable that the double-line breakage detection device also comprises other functional modules such as connecting members, which are known to those skilled in the art and will not be described here.
[0024] The fixing device 10 comprises a mounting rod 11, at least one hanging rod 12 fixedly arranged at one end of the mounting rod 11, and a mounting seat 13 arranged at the other end of the hanging rod 12. The mounting rod 11 is used to be connected with a winding machine. The hanging rod 12 is arranged obliquely upward. The hanging rod 12 is used to connect the mounting rod 11 and the wire passing device 30, and to assist in mounting the wire passing device 30. The mounting seat 13 is used to mount the wire passing device 30 and bear various functional components of the wire passing device 30. The mounting seat 13 comprises a mounting seat body 131, a support block 132 arranged in the direction away from the mounting rod 11, and two first mounting blocks 133 arranged on both sides of the mounting seat body 131 in the arrangement direction of the wire passing devices 30. The support block 132 is used to assist in mounting the wire passing device 30. The two first mounting blocks 133 are used to mount the detection devices 20. The hanging rod 12 penetrates through the mounting seat body 131 and is adjustably connected with the mounting seat body 131 through a connecting member.
[0025] The single detection device 20 is fixed to the single first mounting block 133 by a connecting member. In the embodiment, the detection device 20 uses a slot-shaped micro photoelectric sensor. The detection device 20 is provided with a detection device body 21 and a sensing slot 22 arranged on the detection device body 21 and facing the wire passing device 30. The sensing slot 22 is provided with a transmitting end and a receiving end corresponding to the transmitting end on opposite sides of the sensing slot 22. The relevant circuit is arranged in the detection device 20. The detection device 20 detects whether there is an obstruction in the sensing slot 22 by changing the light signal. The detection device 20 is a general technology, which will not be described here.
[0026] The wire passing device 30 includes a wire passing structure 31 mounted on the support block 132, two wire passing pulleys 32 mounted on the two sides of the suspension rod 12, and two wire blocking blocks 33 for preventing the wire from jumping.
[0027] The wire passing structure 31 includes a connecting branch plate 311 and a mounting branch plate 312 connected to the connecting branch plate 311. The wire passing structure 31 is arranged on the side of the support block 132 away from the mounting rod 11. The wire passing structure 31 is used to confirm and guide the position of the wire. The mounting branch plate 312 is provided with two porcelain eyes 3121. The wire passes through the porcelain eyes 3121 to the wire passing pulleys 32.

[0029] The wire blocking block 33 is arranged on both sides of the supporting block 132 through a connecting piece. The two wire blocking blocks 33 in the same overline device 30 are arranged above the overline pulley 32 at intervals, so as to prevent the wire from deviating from the overline pulley 32 due to too fast transportation speed, thereby avoiding operation failure. The wire blocking block 33 is provided with a wire blocking rod facing the overline groove 323, so as to prevent the wire from jumping during transportation.
[0030] Compared with the prior art, the double wire broken line detection device provided by the utility model detects whether the wire is broken through the overline pulley 32 and the detection device 20. The outer disc 322 of the overline pulley 32 is provided with a detection groove 3221, and the outer disc 322 is arranged in the sensing groove 22 to block between the emitting end and the receiving end. The rotation path of the detection groove 3221 partially overlaps the light propagation path of the emitting end and the receiving end. When the wire is transported, the detection groove 3221 rotates with the outer disc 322, and the signal between the emitting end and the receiving end changes regularly. When the wire is broken, the receiving end continuously receives a single block or transmission signal, and the overline pulley 32 can be detected to stop rotating, that is, the wire is broken.
