Design a roller shutter door structure that uses a sprocket and chain drive system. The first sprocket is located below the loading platform frame, allowing the roller shutter door to fall onto the loading platform frame plane to form a closure. The automatic closure is achieved by using arc-shaped roller shutter blades and motor drive, preventing flames from escaping through the gaps. The transition sprocket is used to change the way the door goes around the load, saving space.
The stacker crane loading platform is completely enclosed, preventing flames from escaping through gaps, improving fire safety, and optimizing the overall space utilization of the design.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of stacker crane loading platform technology, and in particular to a roller shutter door structure that can realize the closure of the stacker crane loading platform. Background Technology
[0002] With the rapid development of the lithium battery industry, introducing logistics automation technology into the lithium battery production process has become a mainstream trend in the industry. As one of the core equipment of automated warehouses, stacker cranes play an important role in connecting the upstream and downstream processes in the entire system. Lithium batteries are generally very safe, but they can occasionally catch fire or explode. Therefore, the design requirements for safety are more stringent. As a carrier for handling goods, the loading platform is extremely dangerous if it catches fire and moves through the shelves. The resulting casualties and property losses are incalculable. Therefore, if the goods on the loading platform catch fire, they need to be sealed off to prevent the fire from spreading rapidly and affecting the goods inside the shelves.
[0003] Currently, the rolling shutter door mechanism of existing stacker cranes can only lower the blades to be flush with the lower surface of the goods, leaving a gap of more than 100mm between the upper surface of the forks and the fixed surface. If the goods catch fire, there is a possibility that flames could escape through this gap, which is very dangerous for fire safety. If such a fireproof mechanism is installed on the loading platform, the loading platform often needs to be made very high, which is very disadvantageous to the overall design. Utility Model Content
[0004] The purpose of this invention is to address the problem that in existing stacker cranes, the roller shutter door mechanism's blades can only fall flush with the lower surface of the goods, leaving a gap of over 100mm between the upper surface of the forks and the fixed surface. If the goods catch fire, there is a risk that flames could escape through this gap, posing a significant fire safety hazard. Furthermore, incorporating such a fire-resistant mechanism on the loading platform often requires a very high platform, which is detrimental to the overall design. This invention proposes a roller shutter door structure that can achieve complete enclosure of the stacker crane's loading platform.

[0006] A roller shutter door structure capable of enclosing the loading platform of a stacker crane includes a loading platform frame, two side sealing plates on the top of the loading platform frame, and a top sealing plate between the two side sealing plates. A first sprocket, a second sprocket, a first transition sprocket, and a second transition sprocket are rotatably connected to one side of each side sealing plate. A chain is driven between the first sprocket, the second sprocket, and the second transition sprocket. The chain is wound around the first transition sprocket. A roller shutter blade is fixedly connected between the two chains. The first sprocket is located below the loading platform frame.
[0007] Furthermore, a first positioning detection blade is fixedly connected to one side of the chain.
[0008] Further, one side of the chain is fixedly connected with a second to-position detection vane.
[0009] Further, one side of the side sealing plate is fixedly connected with a to-position detection switch support, and a to-position detection switch is fixedly connected to the to-position detection switch support.
[0010] Further, the other side of the side sealing plate is fixedly connected with two motors, and output ends of the two motors are connected with the first sprocket and the second sprocket respectively.
[0011] Further, the second sprocket and the second transition sprocket are located on the same plane.
[0012] Further, the roller shutter vane is in an arc structure.
[0013] The utility model discloses a beneficial effect is:
[0014] 1. through the first sprocket below the loading platform frame setting can make the roller shutter door structure can fall to the loading platform frame plane and form closed, thereby avoiding producing the gap, and further avoiding the spark from the gap in.
[0015] 2. through the first transition sprocket and the second transition sprocket change the straight up and down mode to the roundabout, and the height is compressed down, and the space is saved. BRIEF DESCRIPTION OF DRAWINGS
