[0046] A method for using a flat iron trolley for stacking steel rails in layers includes the following steps: S1. Preparatory work for the preliminary stages: a. Based on the material handling design of the trolley and shovel, flat iron is stacked in layers to form a three-dimensional warehouse for storing flat iron, which facilitates the storage and retrieval of flat iron. b. Based on the stacking position and state of the rails, as well as the location of the automated warehouse, set the travel path and operation instructions for the take-up and take-down trolley; c. Match the shuttle device for the deployment and retrieval of the trolley according to the driving path and workflow; d. Determine the amount of flat iron to be used each time based on the length of the rail.

[0047] S2. Flat iron retraction and extension: a. When laying flat iron: The take-up and release trolley moves along the set route until the top of the rail. The take-up and release trolley performs phased movements and stops after moving a set distance. It pauses for a certain period of time and then continues to move. During the pause, the take-up and release mechanism on the rear side of the take-up and release trolley moves. The chain drives the shovel to move. The shovel moves down and the flat iron is placed on the rail until the laying is completed. b. When recovering flat iron, the take-up and release trolley moves along the set route until it reaches the top of the rail. The take-up and release trolley performs phased movements and stops after moving a set distance. It pauses for a certain period of time and then continues to move. During the pause, the take-up and release mechanism at the front of the take-up and release trolley in the direction of movement works. The chain drives the shovel plate to move. The shovel plate moves up and lifts the flat iron on the rail to recover it.

[0048] S3. Finally, the trolley is reset along the set route, and the flat iron it carries is placed in the set position, or the flat iron is taken out again to prepare for the subsequent flat iron laying work.

[0049] When the flat iron is being retracted or extended, the servo motor drives the first bevel gear, the second bevel gear, and the main shaft to rotate via the motor shaft. The main shaft drives the first sprocket and the chain to rotate (the chain rotates in opposite directions under the action of the forward and reverse rotation of the servo motor). The chain drives the shovel plate to move. When the shovel plate is lifted, the flat iron is retracted. When the shovel plate is lowered, the flat iron is placed.

[0050] When the flat iron is extended or retracted, the servo motor rotates the same number of times each time, and the shovel plate rises or falls the same distance each time.

[0051] In this invention, the rails are stacked layer by layer, with flat iron laid between the layers to increase the stability of the entire rail stack. The number of stacked layers is approximately 10.

[0052] For example, if a steel rail is 100 meters long and is grouped into sets of 14, with a flat iron placed approximately every 5 meters (equal spacing or spacing determined by the site), 18 flat irons are needed. Currently, the largest storage yard can hold 91 steel rails per layer. After automation, the number will be adjusted to multiples of 14. Calculated in 6 groups, each layer will require a total of 18 * 6 = 108 rails.

[0053] For example, the existing rail has a bottom width of 150mm and a height of 176mm. The flat iron is designed with a width of 100mm * thickness of 10mm * length of 2300mm, and a weight of approximately 18kg / piece. (150mm * 14 pieces + 100mm over each side = 2300mm).

[0054] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions conceived without inventive effort should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
