[0031] The roller conveyor line 3 is located on the side of the feed end 202 of the continuous lifting device 2, and its height matches the horizontal height of the feed end 202, so that the material can be smoothly transferred from the roller conveyor line 3 to the feed end 202 of the elevator. The material is placed on the roller conveyor line 3, and as the conveyor line moves, it gradually approaches and contacts the feed end 202 of the elevator. When the material reaches the feed end 202 of the elevator, the reduction motor 204 starts to work, and the output shaft of the reduction motor 204 drives the driving sprocket 5 to rotate, wherein the driving sprocket 5 is connected to the driven sprocket 6 through the first chain 7, thereby driving the driven sprocket 6 to rotate. The driven sprocket 6 is fixedly connected to the first drive shaft 206, thereby driving the first drive shaft 206 to rotate; two sets of first double-row sprockets 8 with the same structure are installed on the first drive shaft 206, thereby driving the first double-row sprocket 8 to rotate as the first drive shaft 206 rotates; at the same time, the two sets of first double-row sprockets 8 installed on the first drive shaft 206, the two sets of second double-row sprockets 9 on the second drive shaft 208 and the two sets of third double-row sprockets 10 on the tensioning shaft 210 are respectively connected to each other through the outer chain 212 and the inner chain 213, forming a closed-loop transmission system; wherein, the outer chain The outer chain 212 passes around the outer sprockets of the first double-row sprocket 8, the second double-row sprocket 9 and the third double-row sprocket 10, while the inner chain 213 passes around the inner sprockets of the first double-row sprocket 8, the second double-row sprocket 9 and the third double-row sprocket 10; as the first drive shaft 206 rotates, the outer chain 212 and the inner chain 213 start to move synchronously, wherein the tray 11 between the outer chain 212 and the inner chain 213 is also lifted accordingly; the tray 11 is connected to the outer chain 212 and the inner chain 213 through the connecting structures at both ends thereof (such as the tray chain 1101, the outer chain connecting ear seat 1104 and the inner chain connecting ear seat 1105). 13 is fixedly connected to ensure stability during the lifting process; driven by the chain, the pallet 11 gradually rises from the feed end 202 to the discharge end 203, and the materials on the pallet 11 are also lifted during the rising process; when the pallet 11 rises to the discharge end 203, its height matches the horizontal height of the transport trolley 4 on the steel platform 1; at this time, the materials on the pallet 11 can be easily transferred to the transport trolley 4, or directly taken away by the transport trolley 4 for the next operation; the transport trolley 4 can move freely on the steel platform 1 to transport the materials to the designated location or the next process.

[0032] During the entire lifting process, the tensioning shaft 210 and the third double-row sprocket 10 thereon play the role of adjusting the chain tension. By adjusting the height position of the tensioning shaft 210, it can ensure that the outer chain 212 and the inner chain 213 always maintain an appropriate tension state to avoid looseness and shaking; in addition, the outer chain guide rails 13 and the inner chain guide rails 14 arranged above and below the frame 201 also help to maintain the smooth operation of the outer chain 212 and the inner chain 213, reducing wear and noise; the continuous lifting device 2 of the utility model can continuously lift materials from low to high places to achieve continuous operation. Through reasonable automatic control design, continuous, stable and efficient lifting and transportation of materials are achieved, which not only improves production efficiency, but also reduces labor costs and safety risks, providing a reliable solution for the fields of industrial automation and material handling.

[0033] Please refer to Figure 6 、 Figure 7 As an embodiment of the present invention, the pallet 11 includes two pallet chains 1101, wherein the first support bar 1102 and the second support bar 1103 are respectively provided at both ends of the pallet chain 1101; the first support bar 1102 is respectively provided with an outer chain connecting ear seat 1104 at both ends, wherein the outer chain connecting ear seat 1104 is fixedly connected to the inner side edge of the outer chain 212; the second support bar 1103 is respectively provided with an inner chain connecting ear seat 1105 at both ends, wherein the inner chain connecting ear seat 1105 is fixedly connected to the inner side edge of the inner chain 213; a plurality of shelves 1106 are arranged side by side above the pallet chain 1101, wherein the shelves 1106 are arranged at intervals, and the bottom ends of the shelves 1106 are respectively fixedly connected to the two pallet chains 1101.

[0034] In the above-mentioned scheme, the pallet 11 is used to carry and transport materials, wherein the pallet 11 is composed of two pallet chains 1101, and the two ends of each pallet chain 1101 are respectively connected to the first support bar 1102 and the second support bar 1103. This design not only enhances the stability of the pallet 11, but also enables it to adapt to the transmission structure of the outer chain 212 and the inner chain 213; the first support bar 1102 is located at one end of the pallet chain 1101, and the two ends thereof are designed with outer chain connecting ear seats 1104, wherein the outer chain connecting ear seat 1104 is tightly connected to the inner side of the outer chain 212 by some fixing method (such as welding, bolt connection, etc.), ensuring that the pallet 11 can rise or fall smoothly with the movement of the outer chain 212 during the lifting process; the second support bar 1103 corresponds to the first support bar 1102 and is located at the other end of the pallet chain 1101. The two ends of the second support bar 1103 are equipped with inner chain connecting ear seats 1105, wherein the inner chain connecting ear seats 1105 are also connected to the inner side edges of the inner chain 213 in a fixed manner, thereby realizing the synchronous movement of the pallet 11 and the inner chain 213; a plurality of shelves 1106 are arranged side by side above the pallet chain 1101, wherein the shelves 1106 are used to place and support materials, and a certain interval is maintained between the shelves 1106 to facilitate the rotation between two adjacent shelves 1106; the two ends of the bottom of the shelf 1106 are respectively fixedly connected to the two pallet chains 1101 to ensure that the shelf 1106 and the materials thereon can remain in a horizontal state during the lifting process.

[0035] When the reduction motor 204 starts and drives the driving sprocket 5 to rotate, the outer chain 212 and the inner chain 213 start to move synchronously. Since the two ends of the pallet chain 1101 are respectively connected to the outer chain 212 and the inner chain 213, the pallet 11 also rises with the movement of the outer chain 212 and the inner chain 213; during the lifting process, the first support bar 1102 and the second support bar 1103 on the pallet chain 1101 are respectively tightly connected to the chain through the outer chain connecting ear seat 1104 and the inner chain connecting ear seat 1105, ensuring that the pallet 11 and the materials thereon can rise smoothly and stably; when the pallet 11 rises to the discharge end 203 of the elevator, its height matches the transport trolley 4 on the steel platform 1 or the receiving device of the next process; at this time, workers or automated equipment can take the materials from the shelf 1106 and place them on the transport trolley 4 or on the receiving device; after the material is unloaded, the pallet 11 continues to descend with the movement of the outer chain 212 and the inner chain 213, and returns to the feed end 202 of the elevator to wait for the next loading; because the two ends of the pallet chain 1101 are connected to the chain, the pallet 11 can also maintain a stable and stable state during the descent process; through reasonable automation control design, the continuous operation of the elevator can be achieved. When the pallet 11 unloads materials at the discharge end 203, the feed end 202 can simultaneously carry out the next material loading work; in this way, the elevator can continuously lift the material from a low place to a high place, realizing efficient and continuous material transportation; through fine structural design and reasonable automation control strategy, the elevator can meet various material transportation needs, and provides a reliable solution for the fields of industrial automation and material handling.

[0036] Please refer to Figures 2 to 5 As an embodiment of the present invention, the outer chain 212 is respectively engaged with the outer sprockets of the first double-row sprocket 8, the second double-row sprocket 9 and the third double-row sprocket 10 for transmission, wherein the inner chain 213 is respectively engaged with the inner sprockets of the first double-row sprocket 8, the second double-row sprocket 9 and the third double-row sprocket 10 for transmission.

[0037] In the above scheme, the outer chain 212 passes around the outer sprockets of the first double-row sprocket 8, the second double-row sprocket 9 and the third double-row sprocket 10, and transmits power through the rotation of the first double-row sprocket 8, the second double-row sprocket 9 and the third double-row sprocket 10, and is connected to the first support bar 1102 of the pallet chain 1101 through the outer chain connecting ear seat 1104, jointly bearing the weight of the pallet 11 and the material; the inner chain 213 corresponds to the outer chain 212, and the inner chain 213 passes around the first double-row sprocket The inner sprockets of row sprocket 8, second double-row sprocket 9, and third double-row sprocket 10 are connected to the second support bar 1103 of pallet chain 1101, ensuring the stability and balance of pallet 11 during the lifting process. The meshing transmission of outer chain 212 and inner chain 213 with the double-row sprockets plays a vital role in the continuous handling hoist of steel platform 1. They not only achieve continuous and smooth power transmission, but also ensure the stability and balance of pallet 11 and materials during the lifting process. Through sophisticated structural design and reasonable automation control strategies, this hoist can meet various material transportation requirements and provide a reliable solution for the fields of industrial automation and material handling.

[0038] Please refer to Figure 5 、 Figure 7 As an embodiment of the present invention, two groups of first supporting rollers 12 are provided on the first driving shaft 206, wherein the first supporting rollers 12 are fixedly connected to the first driving shaft 206, and the spacing between the two groups of first supporting rollers 12 corresponds to the pallet chain 1101.

[0039] In the above-mentioned scheme, the first supporting wheel 12 is firmly fixed on the first driving shaft 206 by a key connection. This fixed connection ensures that the supporting wheel can rotate synchronously when the first driving shaft 206 rotates; the positions of the two sets of first supporting wheels 12 on the first driving shaft 206 are carefully designed, and the spacing between them matches the width of the pallet chain 1101 and the spacing between the chain links; this design ensures that the pallet chain 1101 can pass through the supporting wheels smoothly without getting stuck or deflected; the main function of the first supporting wheel 12 is to support the weight of the pallet chain 1101 and its pallet 11 and provide it with necessary guidance; when the pallet chain 1101 is in the first When moving driven by a drive shaft 206, the first supporting wheel 12 can reduce the friction between the pallet chain 1101 and the first drive shaft 206, thereby reducing energy consumption and wear; since the contact area between the first supporting wheel 12 and the pallet chain 1101 is large, they can disperse the pressure on the pallet 11 and improve the load-bearing capacity and service life of the pallet 11; since the first supporting wheel 12 is fixedly connected to the first drive shaft 206, when the first drive shaft 206 rotates, the first supporting wheel 12 will also rotate at the same speed and direction. This synchronous transmission ensures that the pallet chain 1101 can move continuously and smoothly, thereby realizing continuous handling of materials.

[0040] See also Figure 2 As an embodiment of the present invention, two sets of outer chain guide rails 13 are symmetrically provided on both sides above the frame 201, and the outer chain guide rails 13 are adapted to the outer chain 212; two sets of inner chain guide rails 14 are symmetrically provided on both sides below the frame 201, wherein the inner chain guide rails 14 are adapted to the inner chain 213.

[0041] In the above-mentioned scheme, the outer chain guide rails 13 are installed on both sides of the upper part of the frame 201 in a symmetrical arrangement. The outer chain guide rails 13 are usually designed to match the shape and size of the outer chain 212 to ensure that the outer chain 212 can slide smoothly on the outer chain guide rails 13; the main function of the outer chain guide rails 13 is to guide the outer chain 212 to move along a predetermined path and maintain its stability in the horizontal direction. Through the precise design of the outer chain guide rails 13, it can be ensured that the outer chain 212 will not deviate from the track during movement, thereby Improve the accuracy and reliability of handling; In addition to the guiding function, the outer chain guide rail 13 also carries the weight of the outer chain 212 and the pallet chain 1101 connected thereto. By dispersing the pressure on the outer chain 212, the outer chain guide rail 13 can reduce the friction between the outer chain 212 and the frame 201, thereby extending the service life of the outer chain 212 and the frame 201; the outer chain guide rail 13 also plays a certain safety protection role, which can prevent the outer chain 212 from colliding with the frame 201 or other components during movement, thereby The inner chain guide rails 14 are installed on both sides of the lower part of the frame 201 and are also arranged symmetrically. The design of the inner chain guide rails 14 also matches the shape and size of the inner chain 213 to ensure that the inner chain 213 can slide smoothly on the inner chain guide rails 14. The main functions of the inner chain guide rails 14 are similar to those of the outer chain guide rails 13, including guiding the movement of the inner chain 213, bearing the weight of the inner chain 213, maintaining the stability of the inner chain 213, and providing safety protection. However, due to the inner chain 213 The chain 213 is usually located inside or below the frame 201, so the inner chain guide rail 14 needs to take space limitations and operational convenience into greater consideration during design and installation; the inner chain guide rail 14 and the outer chain guide rail 13 need to work together to ensure that the inner chain 213 and the outer chain 212 can move synchronously and maintain appropriate tension. Through precise guide rail design and adjustment, it can be ensured that the inner chain 213 and the outer chain 212 always remain stable and coordinated during movement, significantly improving the handling efficiency and reliability of the elevator.
