Abstract
Description
Technical Field
[0001] This utility model relates to the field of stacker crane technology, and in particular to a lifting guide rail mechanism for a stacker crane. Background Technology
[0002] In modern logistics and warehousing systems, stacker cranes are the core equipment for realizing automated storage and retrieval of goods, and their operating efficiency and operational stability are directly related to the overall effectiveness of the warehousing system.
[0003] As the lifting height of stacker cranes increases, the slenderness ratio of the guide rails increases, significantly reducing their anti-tipping capacity. Under eccentric loading conditions, lateral tilting is highly likely to occur, leading to a sharp deterioration in the operational stability of the lifting mechanism. These problems have become key bottlenecks restricting the development of stacker cranes towards higher lifting heights and greater load-bearing capacities, failing to meet the demands of modern warehousing systems for efficient, safe, and stable operation.
[0004] To address the aforementioned issues, we propose a lifting guide mechanism for a stacker crane. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a lifting guide rail mechanism for a stacker crane.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A stacker crane lifting guide mechanism includes a lower guide rail, an upper guide rail, and a lifting guide rail mechanism. The lifting guide rail mechanism includes a support plate, a lifting frame fixedly installed on the upper side of the support plate, symmetrically formed grooves on the inner side of the lifting frame, threaded rods rotatably installed on the inner side of the grooves, synchronous servo motors symmetrically fixedly installed on the upper side of the lifting frame, the output end of the synchronous servo motors rotatably passing through the inner side of the grooves and fixedly connected to the upper end of the threaded rods, a driving wheel and a driven wheel rotatably installed on the bottom of the support plate, and a plurality of folding rods fixedly connected to both sides of the bottom of the support plate, with stabilizing rollers rotatably installed at the ends of the folding rods.
[0008] Furthermore, threaded sleeves are slidably provided on the inner side of the sliding grooves on both sides, and the threaded sleeves are screwed onto the outer side of the threaded rod. A lifting platform is fixedly connected between the two threaded sleeves.
[0009] Furthermore, the lower guide rail is fixedly installed on the workshop floor and a concave guide groove is provided on the upper side of the lower guide rail, and the driving wheel and the driven wheel are both rotatably disposed inside the concave guide groove.
[0010] Furthermore, the stabilizing roller makes rolling contact with both sides of the upper side of the lower guide rail.
[0011] Furthermore, the upper guide rail is fixedly installed on the top of the workshop, and a fixed plate seat is fixedly installed on the top of the lifting frame, the fixed plate seat being snapped and slidably attached to the inner side of the upper guide rail.
[0012] Furthermore, rubber sleeves are fixedly fitted on the outer sides of both the driving wheel and the driven wheel.
[0013] Furthermore, the drive wheel side shaft rotates through to the outside of the support plate and a large gear is fixedly installed at the end of the drive wheel side shaft. A drive motor is fixedly installed on the upper side of the support plate, and a small gear is fixedly installed on the output end of the drive motor.

[0015] Compared with related technologies, the lifting guide rail mechanism of the stacker crane proposed in this utility model has the following beneficial effects:
[0016] In this utility model, the lifting guide rail mechanism of a stacker crane features a lower guide rail and an upper guide rail on its upper and lower sides, respectively.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Reference Figures 1-5 A stacker crane lifting guide mechanism includes a lower guide rail 1, an upper guide rail 2, and a lifting guide mechanism 3. The lifting guide mechanism 3 includes a support plate 31, a lifting frame 34 fixedly mounted on the upper side of the support plate 31, symmetrically formed grooves 36 on the inner side of the lifting frame 34, threaded rods 37 rotatably mounted on the inner side of the grooves 36, and symmetrically fixedly mounted synchronous servo motors 38 on the upper side of the lifting frame 34. The output end of the synchronous servo motor 38 rotatably passes through the inner side of the grooves 36 and the output end of the synchronous servo motor 38... The support plate 31 is fixedly connected to the upper end of the threaded rod 37. The bottom of the support plate 31 is rotatably mounted with a drive wheel 32 and a driven wheel 33. Several folding rods 312 are fixedly connected to both sides of the bottom of the support plate 31. Stable rollers 313 are rotatably mounted at the ends of the folding rods 312. A controller 35 is fixedly mounted on the outer wall of the lifting frame 34. Threaded sleeves 311 are slidably arranged inside the sliding grooves 36 on both sides. The threaded sleeves 311 are screwed onto the outside of the threaded rod 37. A lifting platform 310 is fixedly connected between the two threaded sleeves 311.
[0025] With the above configuration, starting the synchronous servo motor 38 can drive the threaded rods 37 on both sides to rotate synchronously, which in turn drives the threaded sleeves 311 on both sides to move the lifting platform 310 in the middle up and down, providing lifting power for lifting goods.
[0026] In this method, the lower guide rail 1 is fixedly installed on the workshop floor and the upper side of the lower guide rail 1 is provided with a concave guide groove 11. The driving wheel 32 and the driven wheel 33 are both rolled inside the concave guide groove 11, and the stabilizing roller 313 rolls in contact with the two sides of the upper side of the lower guide rail 1.
[0027] With the above configuration, the drive wheel 32 provides power for the translational sliding of the entire lifting guide rail mechanism 3 on the lower guide rail 1. The driven wheel 33 and multiple stabilizing rollers 313 form a multi-point rolling support with the lower guide rail 1, thereby strengthening the support stability of the support plate 31 and improving the stability of the entire lifting guide rail mechanism 3 in translation on the lower guide rail 1.
[0028] In this method, the upper guide rail 2 is fixedly installed on the top of the workshop, and the top of the lifting frame 34 is fixedly installed with a fixing plate 39, which is snapped and slidably attached to the inner side of the upper guide rail 2.
[0029] The sliding engagement between the upper guide rail 2 and the fixed plate seat 39, as described above, provides a limiting effect on the upper side of the lifting guide rail mechanism 3, improves the anti-overturning performance of the lifting guide rail mechanism 3, and enhances its stability when lifting goods.
[0030] In this configuration, rubber sleeves 314 are fixedly fitted on the outer sides of both the driving wheel 32 and the driven wheel 33.
[0031] By setting the rubber wheel sleeve 314 as described above, the surface friction of the driving wheel 32 and the driven wheel 33 is increased, preventing the driving wheel 32 and the driven wheel 33 from slipping on the lower guide rail 1.
[0032] In this configuration, the side shaft of the drive wheel 32 rotates through to the outside of the support plate 31, and a large gear 316 is fixedly installed at the end of the side shaft of the drive wheel 32. A drive motor 317 is fixedly installed on the upper side of the support plate 31, and a small gear 318 is fixedly installed on the output end of the drive motor 317. The small gear 318 meshes with the large gear 316, and a protective cover 315 is provided on the outside of the small gear 318 and the large gear 316.
[0033] With the above configuration, starting the drive motor 317 can drive the pinion 318 to rotate. The pinion 318 meshes with the large gear 316 for transmission, which in turn drives the drive wheel 32 to rotate via the side shaft, providing driving power for the translation of the entire device on the lower guide rail 1.
[0034] The working principle of the lifting guide rail mechanism of the stacker crane provided by this utility model is as follows:
[0035] During operation, when handling goods, the drive motor 317 is first started by the controller 35. The small gear 318 at the output end of the drive motor 317 meshes with the large gear 316 on the shaft of the drive wheel 32, driving the drive wheel 32 to rotate within the concave guide groove 11. Since both the drive wheel 32 and the driven wheel 33 are fitted with rubber sleeves 314, the friction with the lower guide rail 1 is enhanced, preventing slippage. This allows the support plate 31 to drive the entire lifting guide rail mechanism 3 to move smoothly along the lower guide rail 1. During this process, the driven wheel 33 at the bottom of the support plate 31 provides auxiliary rolling support, and the stabilizing rollers 313 at the ends of the two side folding rods 312 roll in contact with the upper sides of the lower guide rail 1, forming multi-point support and further improving stability during translation. Simultaneously, the fixed plate seat 39 at the top of the lifting frame 34 slides within the upper guide rail 2, preventing the upper side of the lifting guide rail mechanism 3 from overhanging and significantly enhancing the overall anti-overturning capability.
[0036] When goods need to be lifted or lowered, the controller 35 controls the synchronous servo motors 38 on both sides to start, and their output drives the threaded rod 37 in the slide 36 to rotate synchronously. Since the threaded sleeve 311 is screwed onto the outside of the threaded rod 37 and is fixedly connected to the lifting platform 310, the rotation of the threaded rod 37 will drive the threaded sleeve 311 to slide up and down along the slide 36, thereby driving the lifting platform 310 to lift and lower smoothly, realizing the vertical transport of goods. Throughout the process, all components work together to ensure the stability of the lifting guide mechanism 3 during translation and lifting, and improve its anti-tipping performance, meeting the needs of modern warehousing systems for efficient, safe and stable operation.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
