Abstract
Description
Technical Field
[0001] This utility model relates to the field of material storage equipment technology, specifically a bidirectional telescopic stacker. Background Technology
[0002] Traditional stacker cranes mostly employ a unidirectional telescopic structure, limiting the stacking range to the length of extension in one direction. This restricts operation in confined spaces or when multidirectional stacking is required. In existing technologies, the drive mechanism of the unidirectional telescopic arm is prone to jamming, and the adjustment precision of the telescopic stroke is low, leading to uneven material stacking. Furthermore, the fixed angle of the unloading device cannot adapt to unloading requirements at different heights and positions, reducing the equipment's versatility.
[0003] Therefore, a bidirectional telescopic stacker needs to be designed to solve the problems mentioned above. Utility Model Content
[0004] The purpose of this invention is to provide a bidirectional telescopic stacker to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A bidirectional telescopic stacker is designed to address the limitations of existing stacking equipment, which features only one telescopic direction and a limited operating range. Through innovative design, it achieves bidirectional synchronous telescopic operation, significantly improving stacking efficiency and flexibility. The bidirectional telescopic stacker mainly consists of a frame, a main telescopic mechanism, a secondary telescopic mechanism, and a connecting seat. The main telescopic mechanism includes a main base, a main telescopic arm, and a main sliding plate. The main base is fixed to one side of the frame via the connecting seat, and the main telescopic arm slides along a guide rail on the main base via the main sliding plate. The secondary telescopic mechanism is similar in structure to the main telescopic mechanism, including a secondary base, a secondary telescopic arm, and a secondary sliding plate. The secondary base is fixed to the other side of the frame via the connecting seat, and the secondary telescopic arm slides along a guide rail on the secondary base via the secondary sliding plate. The connecting seat, as a key connecting component, effectively integrates the connection between the main and secondary telescopic mechanisms and the frame, providing a stable structural foundation for bidirectional synchronous telescopic operation.
[0007] Furthermore, both the main sliding plate of the main telescopic mechanism and the secondary sliding plate of the secondary telescopic mechanism are made of alloy steel and have undergone nitriding treatment. This treatment significantly improves the wear resistance and hardness of the sliding plates, extends their service life, and ensures stable sliding during the telescopic process. Anti-deviation baffles are installed on both sides of the guide rails of the main and secondary bases. The gap between the baffles and the main and secondary sliding plates is ≤2mm, effectively limiting the deviation of the sliding plates and ensuring the accuracy of the telescopic direction. Simultaneously, self-lubricating copper strips are embedded in the rail surface, with a lubrication cycle of ≥720 hours, reducing frictional wear between the rails and the sliding plates, lowering maintenance frequency, and saving labor costs.
[0008] Furthermore, the extension and retraction of the main and auxiliary telescopic booms are achieved by a drive motor linked by a pulley assembly. This pulley assembly includes a first pulley, a second pulley, a third pulley, and a drive belt. The output shaft of the drive motor is connected to the first pulley, which synchronously drives the pulleys of the main and auxiliary sliding plates via the drive belt. The drive belt is a synchronous toothed belt, ensuring good synchronization and high transmission efficiency, thus guaranteeing precise synchronous extension and retraction of the main and auxiliary telescopic booms.
[0009] Furthermore, the extension stroke ratio between the main telescopic boom and the auxiliary telescopic boom is 1:1.2-1:1.5, and the maximum total extension length can reach 3-4 times the frame length, greatly expanding the operating range; the stroke control accuracy reaches ±3mm, ensuring the accuracy of the material stacking position. In addition, the ends of the main telescopic boom and the auxiliary telescopic boom are equipped with detachable hopper connecting seats, which include quick-release latches and positioning pins, making the hopper replacement time ≤2 minutes, facilitating quick hopper replacement according to different material requirements, improving the equipment's versatility and operating efficiency.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This utility model, through the design of a bidirectional telescopic stacker, achieves the following effects: 1. The main and auxiliary telescopic mechanisms employ a bidirectional synchronous telescopic design, extending the stacking range to 3-4 times the frame length, enabling multi-area operation, reducing equipment movement frequency, and increasing stacking efficiency by over 50% in complex storage spaces, thus solving the problem of limited stacking range in traditional unidirectional structures; 2. The main and auxiliary sliding plates are made of alloy steel and nitrided, significantly improving surface hardness, reducing the friction coefficient to below 0.15, and slowing wear rate by 60%, effectively preventing telescopic jamming and improving equipment stability and service life; 3. The drive motor achieves bidirectional synchronous transmission through a pulley system, controlling the response time difference between the main and auxiliary telescopic arms to within 0.5 seconds, ensuring accurate stacking positioning. The material stacking uniformity is improved by 40% with a thickness of ±3mm, solving the problem of poor synchronization in traditional single-drive structures; 4. Synchronous toothed belt drive is adopted, increasing the transmission efficiency to over 98%, eliminating slippage, and extending the service life to over 8000 hours, reducing belt replacement frequency and lowering maintenance costs; 5. Anti-deviation baffles are set on both sides of the guide rail, combined with self-lubricating copper strips, controlling the lateral deviation of the sliding plate to within 2mm, reducing component wear rate by 50%, and extending the self-lubrication cycle to over 720 hours, reducing manual maintenance workload; 6. The telescopic arm end adopts a quick-release locking buckle and positioning pin connection structure, shortening the hopper replacement time to within 2 minutes, improving efficiency by 80% compared to the traditional bolt connection method, and meeting the needs of rapid switching of hopper types for different materials.
