Abstract
Description
Technical Field
[0001] This application relates to the field of automated warehouse technology, and in particular to an extendable track gantry crane device for automated warehouses. Background Technology
[0002] Currently, in automated warehouses, gantry cranes (bridge cranes) are the core handling equipment, which typically run along fixed tracks and are responsible for the storage, retrieval, and transportation of goods.
[0003] In actual warehousing operations, operators use a control system to direct the gantry crane along fixed tracks to complete the vertical lifting and horizontal transport of goods. This standardized design can meet basic warehousing and logistics needs. The gantry crane's operating range depends entirely on the pre-laid track length, and the maximum working stroke is determined during the equipment installation phase.
[0004] However, as modern warehousing and logistics evolve towards greater flexibility and intelligence, the limitations of fixed-track systems have become increasingly apparent over long-term use. Especially when warehouses require functional adjustments or business expansion, operators often need to redesign the equipment layout. In such cases, the modification of fixed tracks involves not only the removal of existing tracks but also the installation and commissioning of new tracks, requiring interruptions to warehousing operations and impacting logistics efficiency. Furthermore, in application scenarios with significant seasonal business fluctuations, fixed-length tracks struggle to flexibly adapt to varying operational needs, resulting in suboptimal equipment utilization.
[0005] Therefore, how to improve the flexibility of the gantry rail while ensuring system stability has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0010] Furthermore, a guide wheel is rotatably mounted on one side of the sliding frame relative to the rack, and the guide wheel abuts against the frame.
[0011] Furthermore, the lifting assembly includes a lifting screw and a lifting motor. The lifting screw is rotatably mounted on the sliding frame, and one end of the lifting screw passes through the lifting frame. The lifting screw is threadedly connected to the lifting frame, and the lifting motor drives the lifting screw to rotate.
[0012] Furthermore, the material handling assembly includes a material handling screw and a material handling motor. The material handling screw is rotatably mounted on the lifting frame. One end of the material handling screw passes through the material handling frame. The material handling screw is threadedly connected to the material handling frame, and the output shaft of the material handling motor is connected to the material handling screw.

[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0026] This application discloses an extendable track gantry crane device for automated warehouses.
[0027] Reference Figure 1 An extendable track gantry crane device for automated warehouses includes a frame 1, a sliding frame 11 slidably mounted on the frame 1, and a lifting frame 12 and a picking frame 13 mounted on the sliding frame 11. A sliding assembly 2 is provided on the frame 1, driving the sliding frame 11 to slide on the frame 1. A lifting assembly 3 and a picking assembly 4 are provided on the sliding frame 11; the lifting assembly 3 drives the lifting frame 12 to rise and fall on the sliding frame 11, and the picking assembly 4 drives the picking frame 13 to pick up goods.
[0028] Reference Figures 2-3 The frame 1 is equipped with slide rails 14, with two sets of slide rails 14 spaced apart on both sides of the frame 1. Slider 15s are mounted on the frame 1 and are installed on the sliding frame 11, engaging with the slide rails 14. In use, the sliding frame 11 slides along the slide rails 14 via the sliders 15. When expansion is needed, the sliding frame 11 can be moved along the frame 1 simply by extending the slide rails 14. To improve the ease of movement of the sliding frame 11 on the frame 1, the sliding assembly 2 includes racks 21. Several racks 21 are mounted on the frame 1, parallel to several slide rails 14, and connected end-to-end on the frame 1. The sliding frame 11 is equipped with a sliding motor 22 and a sliding gear 23. The sliding motor 22 is mounted on the frame 1, and the sliding gear 23 is mounted on the output shaft of the sliding motor 22, meshing with the racks 21. In use, the sliding motor 22 drives the sliding gear 23 to rotate. Since the sliding gear 23 meshes with the rack 21, the sliding frame 11 slides on the slide rail 14 as the sliding gear 23 rotates.
[0029] Furthermore, to improve the stability of the sliding frame 11 as it slides on the frame 1, support rods 24 are provided on the frame 1. Two support rods 24 are spaced apart on one side of the sliding frame 11 opposite to the sliding gear 23, and the two support rods 24 are arranged parallel to each other. Guide wheels 25 are provided on the sliding frame 11. The guide wheels 25 are rotatably mounted on the sliding frame 11 and abut against the support rods 24. As the sliding frame 11 slides on the frame 1, the guide wheels 25 guide the sliding frame 11.
[0030] The lifting frame 12 is arranged in parallel and is rectangular in shape. The lifting components 3 are arranged at intervals on both sides of the width direction of the lifting frame 12. The two sets of lifting components 3 have the same structure and function. Only one set of lifting components 3 will be described below.
[0031] The lifting assembly 3 includes a lifting screw 31 and a lifting motor 32. The lifting screw 31 is vertically oriented and rotatably mounted on the sliding frame 11. One end of the lifting screw 31 passes through the lifting frame 12 and is threadedly connected to the lifting frame 12. The lifting motor 32 is mounted on the sliding frame 11, and its output shaft is connected to the lifting screw 31. In use, the lifting motor 32 drives the lifting screw 31 to rotate. As the lifting screw 31 rotates, the lifting frame 12 rises and falls vertically along the sliding frame 11.
[0032] Reference Figure 4 The material handling frame 13 is installed on one side of the lifting frame 12 along its length. The material handling assembly 4 includes a material handling motor 41 and a material handling screw 42. The drive motor is installed on the lifting frame 12, and the material handling screw 42 is rotatably installed on the lifting frame 12. One end of the material handling screw 42 is connected to the output shaft of the material handling motor 41, and the other end passes through the material handling frame 13, with the material handling screw 42 threadedly connected to the material handling frame 13. In use, as the material handling motor 41 drives the material handling screw 42 to rotate, the material handling frame 13 slides on the lifting frame 12.
[0033] Furthermore, the picking rack 13 is equipped with a picking cylinder 43 and a picking rod 44. The picking cylinder 43 is vertically mounted on the picking rack 13, and the picking rod 44 is mounted on the picking cylinder 43. In addition, a positioning pin 45 is provided on the picking rod 44, and the positioning pin 45 is vertically mounted on the picking rod 44. In use, the picking rack 13 is driven by the picking screw 42 and the picking motor 41 to move to the lower side of the corresponding product. Then, the picking motor 41 drives the picking rod 44 to move closer to the product. The positioning pin 45 on the picking rod 44 positions the product. Then, the product is moved to the lifting frame 12 under the drive of the picking rack 13.
[0034] When the product is placed on the lifting frame 12, in order to reduce the friction between the product and the lifting frame 12, the lifting frame 12 is equipped with support wheels 46, and several support wheels 46 are rotatably mounted on the lifting frame 12. In use, the support wheels 46 support the product. When the picking rack 13 drags the product to the sliding frame 11, the support wheels 46 support the product, reducing the friction between the product and the lifting frame 12.
[0035] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
