[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] like Figure 1-3As shown, a double-column high-speed elevator includes a vertically arranged fixed frame 1. The fixed frame 1 includes a first column 11 and a second column 12 arranged parallel to each other. The top of the first column 11 and the second column 12 is provided with a top plate 13. The first column 11 and the second column 12 are both vertically arranged and connected to the top plate 13 to form the fixed frame 1. The bottom of the fixed frame 1 is provided with a base for support. A vertically movable conveyor frame 2 is provided on the adjacent side of the fixed frame 1. Multiple orderly arranged conveyor rollers 21 are laid on the conveyor frame 2. The conveyor frame 2 and the multiple conveyor rollers 21 are combined to form a transverse conveying line for the product. A drive motor 3 is provided on one side of the first column 11. The output shaft of the drive motor 3 extends to the first column. A plurality of evenly distributed pulley structures 31 are provided between the first column 11 and the second column 12. A drive motor 3 is located on the side of the first column 11, with its output shaft facing the location of the second column 12. The output shaft of the drive motor 3 is connected via a coupling to a main shaft located between the first column 11 and the second column 12. The pulley structure 31 is existing technology, comprising a pulley connected to the main shaft and a fixed housing covering the pulley and connected to a base. The main shaft passes through the fixed housing and can drive the pulley in the pulley structure 31 to rotate. A plurality of synchronous belts 32 are provided between the first column 11 and the second column 12, each connected to a pulley structure 31 for transmission. The timing belt 32 passes through the fixed housing and wraps around the pulley in the pulley structure 31, so that when the pulley in the pulley structure 31 rotates, it can drive the timing belt 32 to move synchronously relative to the pulley structure. The bottom of the top plate 13 is provided with a transmission pulley 131 that is connected to the timing belt 32. The upper and lower sides of the timing belt 32 are respectively connected to the transmission pulley 131 and the pulley structure 31. The upper and lower sides of the timing belt 32 are wrapped around the transmission pulley 131 and the pulley in the pulley structure 31 and are engaged. When the drive motor 3 starts, the output shaft of the drive motor 3 drives the main shaft to rotate synchronously through the coupling. The main shaft drives the pulley in the pulley structure 31 to rotate coaxially. When the pulley in the pulley structure 31 rotates, it drives the transmission pulley 131 to move synchronously relative to the pulley structure. The synchronous belt 32 is driven to move by meshing with the pulley in the pulley structure 31 on the lower side of the synchronous belt 32. The upper side of the synchronous belt 32 moves synchronously around the transmission pulley 131 under the support of the transmission pulley 131. The conveyor frame 2 is fixedly connected to one side of the synchronous belt 32. During the movement of the synchronous belt 32, the conveyor frame 2 connected to one side of the synchronous belt 32 moves up and down with the movement of the synchronous belt 32 to realize the lifting and transfer of goods. The synchronous belt 32 is usually made of non-metallic flexible material, which has less noise when transmitting with the pulley. The synchronous belt 32 is indirectly connected to the conveyor frame 2, which reduces the pressure and wear on the synchronous belt 32 and effectively extends the service life of the components.

[0017] like Figure 2-3As shown, both sides of the conveyor frame 2 are provided with connecting parts 22 that are movably connected to the first column 11 and the second column 12, respectively. The first column 11 and the second column 12 are each provided with a vertically arranged slide rail 14 close to the connecting parts 22. The connecting parts 22 are located on the side of the conveyor frame 2 and extend outwards from the first column 11 and the second column 12. A connecting bar 23 is provided on the side of each connecting part 22 near the conveyor frame 2. The connecting parts 22 are connected by the connecting bar 23, strengthening the structural strength between the two connecting parts 22 and improving the stability and reliability of the structure. Simultaneously, the conveyor frame 2 is movably connected to the fixed frame 1 through the connecting parts 22, allowing part of the overall load of the conveyor frame 2 to be transferred to the connecting parts 22, reducing the burden and wear on the synchronous belt 32, making the movement of the conveyor frame 2 smoother, and ensuring the structural stability of the conveyor frame 2 during movement. This prevents the conveyor frame 2 from shifting or tilting, which would affect the normal lifting action of the conveyor frame 2 and avoid increasing component wear, which could lead to the conveyor frame 2 falling and causing danger. The inner side of the connector 22 is provided with first guide wheels 221 that abut against the side walls of the slide rail 14 on both sides. The two first guide wheels 221 on the inner side of the connector 22 are clamped on both sides of the slide rail 14, forming a lateral limit on the conveyor frame 2 on the first column 11 and the second column 12. The first guide wheels 221 allow the conveyor frame 2 to move up and down along the first column 11 and the second column 12, thereby ensuring the stability of the conveyor frame 2 on the fixed frame 1 and ensuring that the conveyor frame 2 can move up and down stably on the fixed frame 1. The connector 22 is provided with second guide wheels 222 that are perpendicular to the first guide wheels 221 and abut against the sides of the first column 11 and the second column 12 respectively. The axial direction of the second guide wheels 222 is perpendicular to the axial direction of the first guide wheels 222, so that the second guide wheels 222 can abut against the outer side of the first column 11 and the second column 12, increasing the limit on the conveyor frame 2 in another direction, further enhancing the stability of the conveyor frame 2 and ensuring that the conveyor frame 2 can move up and down stably along the first column 11 and the second column 12.

[0018] like Figure 1-2As shown, a vertically arranged connecting plate 24 is provided on the side of the connecting bar 23 near the synchronous belt 32 and connected to the side wall of the conveyor frame 2. The connecting plate 24 is vertically arranged on the side wall of the connecting bar 23. A connecting block 321 is provided on the synchronous belt 32 and connected to the inner side of the connecting plate 24. The connecting plate 24 is provided with multiple vertically arranged strip grooves 241. The upper and lower sides of the connecting plate 24 facing the synchronous belt 32 are provided with fixing blocks 242 that are bolted to the strip grooves 241. The fixing blocks 242 are connected to the connecting plate 24 by bolts to the strip grooves 241. The connection can be adjusted according to the length of the strip groove 241 to adjust the connection position with the connecting block 321, thereby increasing the installation error and ensuring the structural strength during installation. The connecting block 321 is located on the other side of the synchronous belt 32 and is bolted to the fixing block 242. The combination of the connecting block 321 and the fixing block 242 forms a clamping and fixing of the synchronous belt 32, and the connecting block 321 and the fixing block 242 are fastened by bolts, which effectively improves the connection tightness with the synchronous belt 32, so as to stably drive the conveyor frame 2 to lift and lower when the synchronous belt 32 moves.

[0019] like Figure 2 As shown, a counterweight frame 33 is provided on the other symmetrical section of the synchronous belt 32 connected to the conveyor frame 2. The conveyor frame 2 and the counterweight frame 33 are symmetrical to each other. When the conveyor frame 2 is located below the synchronous belt 32, the counterweight frame 33 is located above the other section of the synchronous belt 32, which serves as a counterweight when the conveyor frame 2 is lifted, reducing the driving burden of the synchronous belt 32 when lifting the conveyor frame 2, making the driving of the conveyor frame 2 by the synchronous belt 32 more effortless. The counterweight frame 33 is provided with several stacked counterweight pieces 331. The counterweight pieces 331 are existing technology and are made of metal or other materials. The number of counterweight pieces 331 can be increased or decreased according to the actual counterweight requirements, and they are combined with the counterweight frame 331 to form a counterweight frame. The inner wall of frame 33 forms a limiting position for counterweight plate 331, preventing counterweight plate 331 from sliding within the counterweight frame 33 and affecting lifting stability. Synchronous belt 32 passes through the side wall of counterweight frame 33 from top to bottom. Multiple connecting seats 332 that are bolted to synchronous belt 32 are provided on the side wall of counterweight frame 33. The side wall of counterweight frame 33 is fixed to the connecting seats 332 by bolts, and the connecting seats 332 are fixed to synchronous belt 32 by bolts, thereby fixing counterweight frame 33. This allows for reliable and stable counterweight for lifting conveyor frame 2, ensuring the lifting stability of conveyor frame 2 by the hoist and reducing the load on synchronous belt 32, making lifting more labor-saving.
