[0036] Please see Figure 1-3This utility model provides a technical solution for a reciprocating elevator with horizontal conveying function, comprising:

[0037] Three-dimensional frame 1: The interior is equipped with a top support 22 and a bottom support 2.

[0038] Transmission system: The lower drive shaft 20 and the upper drive shaft 32 are respectively mounted on the bottom and top supports through bearing seats, and sprockets 8 and 14 are fixed at both ends. The conveyor chain 9 is wound around the sprockets to form a closed-loop transmission.

[0039] Lifting mechanism: The vertical slide rail 13 is fixed on both sides of the frame, the lifting slider 11 moves along the slide rail, and the lifting vertical plate 10 connects the slider and the chain to realize the vertical lifting driven by the chain.

[0040] Extended conveying mechanism: The lifting bracket 24 is fixed to the lifting vertical plate 10, and its top is provided with a horizontal slide rail 28 and a slider 27. The conveying plate 7 is fixed to the slider. The lead screw 30 is driven by the servo motor 25, and drives the conveying plate to move horizontally through the lead screw connecting block 29.

[0041] Drive module: Drive motor 15 drives lower drive shaft 20 through pulleys 18, 23 and drive belt 19.

[0042] Counterweight balance: The sliding counterweight block 12 on the smooth rod 21 is fixed to the other end of the chain to counteract the lifting load.

[0043] Fall protection: A fall protection plate 5 supported by a spring 16 is provided on the connecting support plate 3. In the event of an accidental power failure, the spring lifts the fall protection plate to support the conveyor plate.

[0044] Limiting support: The top support roller 6 and the bottom support roller 4 limit the highest / lowest position of the conveyor plate, respectively, to reduce the stress on the chain.

[0045] In practical use, after the drive motor 15 starts, it drives the lower drive shaft 20 to rotate via belt transmission, and the drive chain 9 drives the lifting vertical plate 10 to rise along the vertical slide rail 13. When the conveyor plate 7 reaches the target height, the servo motor 25 drives the lead screw 30 to rotate, causing the conveyor plate to extend along the transverse slide rail 28 to complete the material delivery; in the event of a sudden power failure, the spring 16 pushes the anti-fall plate 5 upward to support the bottom of the lifting bracket 24 and prevent it from falling. The counterweight 12 moves synchronously in the opposite direction with the lifting mechanism to maintain the torque balance of the system.

[0046] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations made to these embodiments within the spirit and principles of this utility model, through conventional substitutions or methods that achieve the same function without departing from the principles and spirit of this utility model, fall within the scope of protection of this utility model.
