[0017] Example
[0018] Such as figure 1 As shown, the anti-collision gear mechanism of the relay-driven fuel transfer device provided by the present invention includes 4 main parts. The anti-collision gear mechanism includes a roller 1, a striker 2, a spring 3, and a pin 4. The striker 2 is connected to the rack of the relay-driven fuel transfer device transport trolley through a pin 4 provided at one end of the striker 2 and a spring 3 provided on the upper part of the striker 2, and the striker 2 can use the pin 4 as a rotation axis When rotating, the pin 4 is used to limit the trajectory of the striker 2. A roller 1 is provided at the lower end of the front of the ram 2, and the roller 1 is in contact with the relay driving gear, and the friction in the relay driving process is changed from sliding friction to rolling friction.
[0019] When the relay drive starts, the roller 1 arranged at the lower end of the front part of the striker 2 contacts the relay drive gear. Due to...
