the driving member 20 is connected to the rail transfer 10 for driving the rail transfer 10 to move along a direction perpendicular to the length direction of the rail; in the embodiment of the present invention, the driving member 20 may be a rack fixed on the bracket 30 and a motor gear structure, a motor screw structure, a pneumatic cylinder, a hydraulic cylinder, a chain sprocket or a timing belt structure fixed on the rail changer 10. The rail transfer device 10 is driven to move transversely as shown in figures 1 and 2 through the control of the driving part 20, so that the rail of the trolley is switched;

the rail transfer 10 is arranged on the bracket 30 in a relatively sliding way; the relative sliding motion here can be a sliding track or a sliding groove arranged on the support 30 in the moving direction of the rail guide 10, and the bottom of the rail guide 10 is provided with a sliding block matched with the sliding track or the sliding groove.

The main rail 40 is fixed on the bracket 30, and a vacant area for the rail transfer device 10 to move is arranged on the bracket 30;

the auxiliary rail 50 is arranged on one side of the bracket 30 and is parallel to the main rail 40 at intervals, and the distance between the auxiliary rail 50 and the main rail 40 is the same as that between the two branch rails;

when the controller needs to switch the trolley, the controller controls the rail switch 10 to move from the first position 100 to the second position 200, so as to move the trolley on the main rail 40 to the position of the auxiliary rail 50 and keep the main rail 40 smooth; as shown in fig. 1 and 2, when the trolley needs to be moved from the main rail 40 to the auxiliary rail 50 on the right side, after the trolley arrives at the auxiliary rail, the trolley stops moving, meanwhile, the driving piece 20 drives the rail transfer device 10 to move from the first position 100 to the second position 200 on the right side, and then the trolley continues to run and arrives at the auxiliary rail 50, so that the purpose of transferring the trolley is achieved;

the branch rail is provided with a positioning component 60, the positioning component 60 is electrically connected with the controller, when the trolley arrives at the branch rail, the positioning component 60 is identified by the trolley and sends a signal to the controller, and the controller controls the rail transfer device 10 to move to a preset position according to an instruction.

In the above embodiment, at least two branch rails are arranged on the rail transfer device 10, and the branch rails are butted with the main rail 40 to keep the smoothness of the main rail 40 at ordinary times.

In the preferred embodiment of the present invention, there is at least one primary rail 40, there are at least two secondary rails 50, and the number of secondary rails on the switch 10 is greater than the number of primary rails 40. The number of the main rail 40, the auxiliary rail 50 and the branch rails is determined according to transportation requirements, and the branch rails can be kept to completely allow the main rail 40 to pass and simultaneously realize a rail transfer function.

In an embodiment of the present invention, the positioning component 60 is a bar code scanner and/or a bar code, a camera device or a wireless identification device fixed on the trolley, and is used for detecting whether the trolley to be transferred is in place. Specifically, a bar code arranged on the trolley identifies the specific type of the vehicle through scanning of a bar code scanner; certainly, the method can also be carried out by adopting video identification or Bluetooth identification and the like; when the controller recognizes that the trolley needs to be diverted to one of the secondary rails 50, the controller controls the driving member 20 to drive the movement of the diverter 10. Through the mode, automatic identification and automatic driving are achieved, and the efficiency and the accuracy of rail transfer are improved. It should be noted that the identification of the position of the trolley arriving at the rail transfer 10 may be realized by providing the above-mentioned bar code scanner, camera device, etc. on the trolley and providing the bar code on the branch rail, and both identification methods are possible.

To prevent damage to a vehicle entering the switch 10 during movement of the switch 10 during travel of the vehicle, the open end of the primary rail 40 toward the switch 10, or the open end of the secondary rail 50 toward the switch 10, or both, of the present invention have a car stop assembly 41, the car stop assembly 41 being used to prevent the vehicle from falling off the remaining rails when the switch 10 is removed.
