Description

Technical Field

[0001] This utility model relates to a transfer mechanism, specifically a transfer mechanism for a material carrier pallet of autoclaved aerated concrete blocks. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks (referred to as "blocks" in the industry) are a lightweight, high-strength, and heat-insulating wall material with excellent sound insulation properties, widely used in the construction industry. Their production process is a continuous and sophisticated industrial process, with core steps including batching, grouting, fermentation, demolding, shaping and cutting, autoclaving, and finished product storage. In this process, the material carrier plate serves as the support and transfer carrier for both the block blanks and finished products, operating throughout the entire stage from demolding to the completion of autoclaving. Its transfer efficiency and stability directly affect the production capacity and operational safety of the entire production line.

[0003] Specifically, after the demolding process is completed, the material carrier pallet with the block blank is placed on the transport trolley on the transport track. The transport trolley is driven to transfer the blank to the shaping and cutting process and the autoclaving process. After the autoclaving and curing process is completed, the formed block finished product needs to be peeled off from the material carrier pallet and transferred to the designated storage area. The empty material carrier pallet needs to be recycled and reused. That is, it is transferred from the transport trolley on the original transport track to the transport trolley on the return track. The return track transports it to the batching and grouting process at the front end of the production line to carry new materials and form a cycle.

[0004] The most common pallet transfer method currently used in the industry is a combination of overhead crane and strapping, which uses an overhead crane in conjunction with flexible strapping to transfer pallets between different track transport trolleys. However, this transfer method has significant drawbacks in practical applications. The flexibility of the strapping is incompatible with the rigid load-bearing requirements of the pallet, resulting in two main problems during the transfer process: inertial lag and positioning sway.

[0005] During the movement of a trolley pulling a pallet along straps, the straps, being a soft structure, lack the rigid support characteristic and cannot achieve instantaneous force transmission. When the trolley starts, accelerates, or stops, the pallet exhibits significant motion lag due to inertia—the trolley has already changed its motion state, while the pallet maintains its original state until the straps' traction force completely overcomes the inertial force, at which point it will follow the trolley's movement. Furthermore, the degree of this lag is positively correlated with the trolley's speed: the faster the speed, the greater the inertial force, the longer the pallet's lag distance and time, and the worse the stability during transport.

[0006] Crucially, when the overhead crane carrying the pallet moves to the top of the transport trolley on the return track, preparing to place the pallet, inertia causes the pallet to sway. Because the pallet itself has a considerable weight (typically several hundred kilograms, depending on the load-bearing capacity), once swaying occurs, it is difficult to quickly quell, making it impossible for operators to accurately control the pallet's landing point. This swaying not only makes it difficult for the pallet to land accurately on the transport trolley on the return track, but may also cause safety hazards such as pallet deviation, tilting, or even falling. If the pallet's landing point deviates too much, manual secondary adjustments are required, further increasing the operational process and labor intensity.

[0007] To mitigate the aforementioned swaying issue, the industry typically addresses it by reducing the crane's operating speed. At low speeds, inertial forces are significantly reduced, alleviating the lag in the pallet load and greatly improving stability during movement. This also ensures accurate positioning on the transport trolley, achieving near-precise placement. However, this speed-for-precision solution presents a trade-off between accuracy and efficiency: reduced crane speed directly lengthens the transfer cycle of a single pallet, decreasing the number of pallets that can be transferred per unit time. For large-scale autoclaved aerated concrete (AAC) block production lines, the pallet circulation efficiency directly determines the production line's cycle time. Reduced pallet transfer efficiency leads to bottlenecks such as pallet waiting at upstream processes and pallet accumulation at downstream processes, ultimately significantly reducing the overall production line's capacity.

[0008] Therefore, it is necessary to design a transfer mechanism for autoclaved aerated concrete block carrier pallets to solve the above problems. Summary of the Invention

[0009] The purpose of this utility model is to provide a transfer mechanism for autoclaved aerated concrete block material pallets that can ensure the stability of transfer, ensure the accurate landing point of the material pallet, and effectively improve the transfer efficiency.

[0010] The technical solution of this utility model is: A transfer mechanism for a pallet of autoclaved aerated concrete (AAC) blocks comprises a truss, a support plate, guide rods, a lifting cylinder, a hanger, limiting wheels, and a hanging plate arranged in parallel. The mechanism is characterized in that: a support plate is movably mounted on the truss via rollers, and guide rods are respectively provided at both ends of the bottom of the support plate; a lifting cylinder is arranged in parallel on the support plate, and a hanger is connected to the piston rod end of the lifting cylinder. The hanger is H-shaped, and multiple sets of limiting wheels are installed at both ends of the hanger via short shafts to limit the relative position of the hanger and the guide rods, with the limiting wheels rollingly connected to the guide rods; and hanging plates are respectively provided at both ends of the bottom of the hanger.

[0011] The aforementioned limiting wheels include two, each disposed at both ends of the side of the hanger, and the limiting wheels are in rolling connection with the side of the guide rod.

[0012] The limiting wheel is in rolling connection with the limiting groove provided on the guide rod on one side of the hanger.

[0013] The roller is equipped with a hydraulic motor.

[0014] A positioning cylinder is installed on the hanger above the hanging plate, and a pressure plate is installed at the end of the piston rod of the positioning cylinder.

[0015] A hydraulic station is provided in the middle of the support plate, and the hydraulic station is connected to the positioning cylinder, the hydraulic motor and the lifting cylinder respectively.

[0016] The beneficial effects of this utility model are as follows: The transfer mechanism of this autoclaved aerated concrete (AAC) block pallet uses limiting wheels to rigidly connect the hanger, guide rod, and support plate. This overcomes the inertia of the pallet during transfer, maintaining the relative position of the pallet and support plate, preventing swaying during descent, and ensuring accurate placement of the pallet on the transport trolley. Simultaneously, the rigid connection prevents swaying, effectively increasing the transfer speed and shortening the transfer time, thus accelerating the production cycle and improving efficiency. This solves the problems of inaccurate pallet placement or low transfer efficiency caused by inertia in existing transfer methods. Attached Figure Description

[0019] The transfer mechanism for the autoclaved aerated concrete (AAC) block carrier pallet consists of a truss 1, a support plate 2, guide rods 3, a lifting cylinder 4, a hanger 5, limiting wheels 6, and a hanging plate 7 arranged in parallel. The support plate 2 is movably mounted on the truss 1 via rollers 8. Guide rods 3 are respectively provided at both ends of the bottom of the support plate 2. The lifting cylinder 4 is arranged in parallel on the support plate 2. The piston rod end of the lifting cylinder 4 is connected to the hanger 5. The hanger 5 is "H" shaped. Multiple sets of limiting wheels 6 are installed at both ends of the hanger 5 via short shafts 9 to limit the relative position between the hanger 5 and the guide rods 3. The limiting wheels 6 are tumbling connected to the guide rods 3. Hanging plates 7 are respectively provided at both ends of the bottom of the hanger 5 to support the carrier pallet, thereby driving the carrier pallet to transfer. The function of the lifting cylinder 4 is to drive the lifting frame 5 to rise and fall. During the lifting process of the lifting frame 5, the lifting plate 7 supports the material pallet, lifting the material pallet upward and causing it to detach from the transport trolley, thereby driving the material pallet to move. The function of the limiting wheel 6 is to limit the relative position of the lifting frame 5 and the support plate 2 by working with the guide rod 3, thereby limiting the relative position of the lifting plate 7 and the support plate 2. When the lifting plate 7 supports the material pallet, the friction between the lifting plate 7 and the material pallet can help the material pallet overcome its inertia, thus allowing the material pallet to move synchronously with the support plate 2. This prevents the material pallet from swaying due to inertia when it is placed, and allows the material pallet to be placed accurately and conveniently on the transport trolley. Meanwhile, due to the rigid interaction between the guide rod 3, the limit wheel 6, the assembly short shaft 9, the hanger 5, and the hanging plate 7, the inertia of the material pallet can be overcome, thereby quickly pulling the material pallet for transfer, which can improve the transfer speed of the material pallet and speed up the production cycle.

[0020] The limit wheel 6 can be configured in the following two ways: Option 1 is: The limiting wheels 6 include two, each located at one end of the side of the hanger 5. The limiting wheels 6 are in rolling connection with the side of the guide rod 3. That is, each set of limiting wheels 6 includes two, with one limiting wheel 6 on one side of the hanger 5 and one limiting wheel 6 on the other side of the hanger 5. By using the limiting wheels 6 located on both sides of the hanger 5 in conjunction with the guide rod 3, the hanger 5 is limited, so that the hanger 5 can maintain its relative position with the guide rod 3.

[0021] Option 2 is: The limiting wheel 6 is in rolling connection with the limiting groove 10 provided on the guide rod 3 on one side of the hanger 5. The limiting groove 10 of the guide rod 3, in conjunction with the limiting wheel 6, limits the hanger 5 and maintains the relative position of the hanger 5 and the guide rod 3.

[0022] The limit wheel 6 can be set using any of the above methods.

[0023] A hydraulic motor 11 is provided on the roller 8 to drive the roller 8 to rotate, thereby driving the support plate 2 to move on the truss 1.

[0024] A positioning cylinder 12 is installed on the hanger 5 above the hanging plate 7, and a pressure plate 13 is installed at the piston rod end of the positioning cylinder 12. The function of the positioning cylinder 12 is to drive the pressure plate 13 downward, and then press the material pallet onto the hanging plate 7 through the pressure plate 13, thereby increasing the friction between the hanging plate 7 and the material pallet. This can further improve the speed of material pallet transfer and the stability of material pallet during the transfer process, thereby further accelerating the production cycle and ensuring that the material pallet can be accurately and stably transferred to the transport trolley on the return track.

[0025] A hydraulic station 14 is provided in the middle of the support plate 2. The hydraulic station 14 is connected to the positioning cylinder 12, the hydraulic motor 11 and the lifting cylinder 4 respectively.

[0026] When the transfer mechanism of the autoclaved aerated concrete (AAC) block pallet is in operation, the transport trolley delivers the pallet to the space between the trusses 1. Then, the lifting cylinder 4 is activated, and the lifting cylinder 4, through the hanger 5, drives the suspended plate 7 downwards until its top surface is below the horizontal plane of the pallet. After the suspended plate 7 reaches its lower position, the hydraulic motor 11 is activated. The hydraulic motor 11, through the roller 8, drives the support plate 2, which in turn drives the guide rod 3, limit wheel 6, assembly short shaft 9, hanger 5, and suspended plate 7 to move towards the pallet until the suspended plate 7 moves laterally to the bottom of the pallet. After the suspended plate 7 reaches its lateral position, the lifting cylinder 4, through the hanger 5, drives the suspended plate 7 upwards, lifting the pallet and separating it from the transport trolley on the transport rail. During the upward lifting of the pallet, the positioning cylinder 12 drives the pressure plate 13 downwards, pressing down on the pallet and increasing the friction between the pallet and the suspended plate 7. After the material pallet reaches its designated position, the hydraulic motor 11 rotates, driving the material pallet towards the transport trolley on the return track. Once the material pallet reaches the transport trolley on the return track, the lifting cylinder 4 drives the material pallet downwards, placing it on the transport trolley on the return track. After the material pallet is in place, the positioning cylinder 12 resets the pressure plate 13, and the lifting cylinder 4 drives the hanging plate 7 downwards, separating it from the material pallet. After the hanging plate 7 reaches its designated position, the hydraulic motor 11 rotates, thereby driving the lifting frame 5 and the hanging plate 7 to move between the return track and the transport track, awaiting the next work cycle.

[0027] The transfer mechanism of this autoclaved aerated concrete (AAC) block pallet uses limiting wheels to rigidly connect the hanger, guide rod, and support plate. This overcomes the inertia of the pallet during transfer, maintaining the relative position of the pallet and support plate, preventing swaying during descent, and ensuring accurate placement of the pallet on the transport trolley. Simultaneously, the rigid connection prevents swaying, effectively increasing the transfer speed and shortening the transfer time, thus accelerating the production cycle and improving efficiency. This solves the problems of inaccurate pallet placement or low transfer efficiency caused by inertia in existing transfer methods.
