Connect one end of the hook 9 of the connecting rope to the hanging ring to complete the connection between the first gantry transfer vehicle and the second gantry transfer vehicle. If the distance measuring device is abnormal, when the distance between the first gantry transfer vehicle and the second gantry transfer vehicle exceeds the range, the connecting rope will limit the first gantry transfer vehicle and the second gantry transfer vehicle, thereby avoiding parts from falling. The tension sensor can detect the tension on the connecting rope in real time. When the tension exceeds the preset value, the braking device of the first gantry transfer vehicle and the second gantry transfer vehicle is also controlled by the control terminal to work, so that the speed of the first gantry transfer vehicle and the second gantry transfer vehicle is reduced until it stops, thereby further improving the safety of transportation.

The control terminal 5 receives the signal and displays the distance value through the display screen 12. On the one hand, the distance is analyzed in real time. If it is judged that the distance between the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 is too large according to the distance, the control terminal 5 controls the braking device of the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 to work, so that the speed of the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 decreases until it stops, and at the same time controls the alarm device 6 to send an alarm signal to the surrounding staff, which is convenient for the staff to deal with it in time, and can effectively prevent the parts from falling off, improve the safety and reliability of transportation, and avoid unnecessary losses;

[0019] By setting the connecting rope 8, before the transfer, the electric reel 7 is started to unwind the connecting rope 8, and the unwinding length depends on the preset maximum distance between the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2. The hook 9 of the connecting rope 8 is connected to the hanging ring 10 at one end to complete the connection between the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2. If the distance measuring device is abnormal, when the distance between the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 exceeds the range, the connecting rope 8 will limit the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2, so as to avoid the falling of parts. The tension sensor 11 can detect the tension of the connecting rope 8 in real time. When the tension exceeds the preset value, the braking device of the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 is also controlled by the control terminal 5 to work, so that the speed of the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 is reduced until it stops, thereby further improving the safety of transfer.

[0020] As a technical optimization solution of the present invention, the outer walls of the crossbeams of the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 are both installed with display screens 12 .

[0026] As a technical optimization solution of the present invention, the connecting rope 8 is a steel wire rope.

[0027] In this embodiment, the connecting rope 8 is a steel wire rope to ensure the tensile strength of the connecting rope 8 .

[0028] Working principle: Before transferring the parts, start the electric reel 7 to unwind the connecting rope 8. The unwinding length depends on the preset maximum distance between the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2. Connect one end of the hook 9 of the connecting rope 8 to the hanging ring 10 to complete the connection between the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2. The parts are hoisted between the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2. The infrared signal transmitter 3 and the infrared signal receiver 4 cooperate with each other to monitor the distance between the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 in real time and transmit it to the control terminal 5. The control terminal 5 receives the signal and displays the distance value through the display screen 12. On the one hand, it analyzes the distance in real time. If it is judged that the distance between the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 is too large according to the distance, the control terminal 5 controls the first gantry transfer vehicle 1 to rotate. The braking devices of the transport vehicle 1 and the second gantry transfer vehicle 2 work to reduce the speed of the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 until they stop, and at the same time control the alarm device 6 to send an alarm signal to the surrounding staff to facilitate timely processing by the staff. If the distance measuring device is abnormal, when the distance between the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 exceeds the range, the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 are restricted by the connecting rope 8, so as to avoid the falling of parts. The tension sensor 11 can detect the tension of the connecting rope 8 in real time. When the tension exceeds the preset value, the braking devices of the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 are also controlled by the control terminal 5 to work, so that the speed of the first gantry transfer vehicle 1 and the second gantry transfer vehicle 2 is reduced until it stops, thereby further improving the transportation safety.
