[0001] This utility model relates to the core technology of warehouse stacking, and in particular to a lifting and guiding device for a double-column stacker crane. Background Technology

[0002] Double-column stacker cranes are the core handling equipment in automated warehouses. They use two columns to support the beams and loading platform, and run along the rack tracks to enable the storage and retrieval of goods in three-dimensional space. However, when lifting or lowering, they need to be guided by guide rails.

[0003] However, during long-term, high-frequency operation, dust, debris, and small impurities in the storage environment easily adhere to the surface of the guide rail. These impurities increase the frictional wear between the guide wheel assembly and the guide rail, causing the lifting action to jam or deviate. This not only reduces the stability and accuracy of cargo lifting but also causes equipment failure and affects the continuity of the production process. Since the guide rail is generally quite long, manual cleaning is difficult. Therefore, a double-column stacker crane lifting guide device is proposed to solve the above problems.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-3This utility model provides an embodiment of a lifting guide device for a double-column stacker crane, comprising a guide rail 1, with a guide wheel assembly 2 slidably connected to the outer wall of the guide rail 1. The guide rail 1 is made of high-strength alloy steel and its surface is precision ground, resulting in minimal straightness error. This provides a precise sliding reference for the guide wheel assembly 2, ensuring that the stacker crane does not deviate during lifting. The guide wheel assembly 2 consists of multiple sets of wear-resistant pulleys made of high-hardness polyurethane material, which have a high degree of fit with the outer wall of the guide rail 1, low sliding resistance, and low noise, enabling smooth lifting of the moving platform 3. The moving platform is fixedly connected to the outer wall of the guide wheel assembly 2. 3. The moving platform 3 is the core component of the stacker crane for carrying goods. It is fixed to the guide wheel assembly 2 by welding, and has a strong structural rigidity. It can evenly transfer the weight of the goods to the guide wheel assembly 2. The upper part of the guide wheel assembly 2 is fixedly connected to the support platform 6. The upper part of the support platform 6 is equipped with a cleaning mechanism 4. The support platform 6 is fastened to the upper part of the guide wheel assembly 2 by welding. It adopts a steel plate splicing structure to provide a stable installation foundation for the cleaning mechanism 4. The cleaning mechanism 4 can remove dust, debris and oil stains from the surface of the guide rail 1 in real time, preventing impurities from entering the guide wheel assembly 2 and affecting the sliding accuracy. At the same time, it reduces component wear and extends the service life of the guiding device.

[0021] Reference Figures 2-4 The cleaning mechanism 4 includes a movable plate 401, which is made of lightweight aluminum alloy profile, making it lightweight yet strong, thus reducing the load on the support platform 6. A dust collection box 402 is fixedly connected to the bottom of the movable plate 401. The dust collection box 402 is welded to the bottom of the movable plate 401, effectively collecting the debris swept off during cleaning and preventing secondary pollution of the guide rail 1. The dust collection box 402 is equipped with a negative pressure dust collection device inside, which can then perform collection work. A connection port 407 is fixedly connected to the upper part of the side of the dust collection box 402 facing the guide rail 1. The connection port 407 expands the absorption range of the dust collection box 402. A cleaning plate 405 is detachably installed on the inner side of the movable plate 401 through a disassembly mechanism 5. The disassembly mechanism 5 makes the replacement and maintenance of the cleaning plate 405 more convenient, and can be completed without complicated tools. To reduce equipment downtime and improve operational efficiency, a monitoring component 403 is installed on the upper part of the dust collection box 402. The monitoring component 403 can monitor the surface cleanliness of the guide rail 1 and the operating status of the guide wheel assembly 2 in real time, allowing staff to remotely monitor the equipment status, detect abnormalities in a timely manner, and handle them. Rollers 406 are rotatably connected to the inner wall of the moving plate 401. The rollers 406 are rotatably connected to the inner wall of the moving plate 401 through bearings, which can assist the moving plate 401 to move smoothly along the guide rail 1 and reduce frictional wear between the moving plate 401 and the guide rail 1. An installation component 404 is installed at the bottom of the dust collection box 402. The installation component 404 can firmly fix the dust collection box 402 on the support platform 6, ensuring that the cleaning mechanism 4 and the guide wheel assembly 2 rise and fall synchronously. The installation component 404 is easy to install and remove, facilitating the overall maintenance of the cleaning mechanism 4.

[0022] Reference Figures 2-4 The cross-section of the connection port 407 is an inverted trapezoid, which gradually expands the suction port from the inside out, creating a stronger negative pressure adsorption area. This efficiently sucks various impurities swept off by the cleaning plate 405 into the dust collection box 402. The side of the cleaning plate 405 away from the moving plate 401 contacts the inner sidewall of the guide rail 1. This close contact ensures thorough cleaning without any blind spots. The cleaning plate 405 is made of wear-resistant rubber, which has good elasticity to conform to the surface of the guide rail 1 without scratching its precision surface. The cross-section of the cleaning plate 405 is an isosceles triangle, allowing it to clean the guide rail 1 whether moving upwards or downwards, resulting in better cleaning. A through groove is provided in the middle of the cleaning plate 405, allowing small impurities to pass through and be collected by the dust collection box 402. 02. Suction enhances the thoroughness of cleaning. The monitoring component 403 includes a fixing block 4031 fixedly connected to the upper part of the dust collection box 402. A camera 4032 is fixedly connected to the top of the fixing block 4031. The fixing block 4031 is welded to the upper part of the dust collection box 402 and adopts a solid metal block structure, which can provide stable support for the camera 4032 and avoid the vibration of the stacker crane causing the camera 4032 to shake and affect the image quality. The camera 4032 is an industrial-grade high-definition camera with dustproof and waterproof functions, which can adapt to the warehouse environment where the stacker crane works. Its real-time images can be transmitted to the control center for remote monitoring by staff. The camera 4032 supports night vision and can work normally in the warehouse with low light. The outer arc surface of the roller 406 contacts the outer wall of the guide rail 1. The contact between the two can reduce friction, thereby facilitating the movement of the moving plate 401.

[0023] Reference Figures 5-6 The mounting assembly 404 includes a connecting plate 4041 fixedly connected to the bottom of the dust collection box 402. The connecting plate 4041 is welded and fixed to the bottom of the dust collection box 402. It is made of thick steel plate, has high strength, and can withstand the weight of the dust collection box 402 and its internal impurities. A positioning block 4042 is fixedly connected to the top of the support platform 6. The inner wall of the positioning block 4042 is threaded through and connected to a limit screw 4043. The positioning block 4042 provides a stable mounting base for the limit screw 4043. The limit screw 4043 is made of thick steel plate. Made of high-strength stainless steel, the threaded surface is smooth, and the resistance during rotation is small, making it easy for workers to manually tighten or disassemble. The bottom of the connecting plate 4041 has a circular groove, and the cylindrical part of the limiting screw 4043 is inserted into the inner wall of the circular groove. The circular groove at the bottom of the connecting plate 4041 and the cylindrical part of the limiting screw 4043 are precisely matched. After insertion, the horizontal displacement of the connecting plate 4041 can be restricted, preventing the cleaning mechanism 4 from swaying left and right during the lifting process. The inner wall of the circular groove is smooth, which facilitates the insertion and removal of the limiting screw 4043.

[0024] Furthermore, the upper part of the positioning block 4042 is provided with a square groove, and the bottom of the connecting plate 4041 is inserted into the inside of the square groove. The square groove on the upper part of the limiting screw 4043 is exactly the same size as the bottom of the connecting plate 4041. The insertion of the connecting plate 4041 into the square groove can further restrict the rotation of the connecting plate 4041, realize all-round positioning, and ensure that the relative position of the cleaning mechanism 4 and the support platform 6 is fixed.

[0025] Reference Figure 4 The disassembly mechanism 5 includes a mounting post 501 fixedly connected to the front of the cleaning plate 405. The mounting post 501 is integrally formed with the front of the cleaning plate 405, made of hard plastic, lightweight yet strong, and can stably fix the cleaning plate 405 inside the moving plate 401. The inner wall of the moving plate 401 has a positioning hole 502, the inner arc surface of which matches the outer arc surface of the mounting post 501. The positioning hole 502 and the outer arc surface of the mounting post 501 are precisely matched. After the mounting post 501 is inserted into the positioning hole 502, the cleaning plate 405 can be quickly positioned without repeated adjustments, improving installation efficiency. The upper part of the moving plate 401 has a round hole, and the inner wall of the moving plate 401 is connected by bolts 503. The cleaning plate 405 is detachably installed on the inner wall of the mounting column 501. The inner arc surface of the circular hole is larger than the threaded surface of the bolt 503. The circular hole on the upper part of the moving plate 401 provides an installation channel for the bolt 503. The design of the inner arc surface of the circular hole being larger than the threaded surface of the bolt 503 facilitates the quick insertion of the bolt 503 without the need for precise alignment of the threaded hole, reducing the difficulty of installation. The edge of the circular hole is chamfered to avoid scratching the surface of the bolt 503. The threaded connection between the bolt 503 and the inner wall of the mounting column 501 is firm, which can tightly fix the cleaning plate 405 on the moving plate 401, ensuring that the cleaning plate 405 does not loosen or shift during operation. The detachability of the threaded connection makes the replacement and maintenance of the cleaning plate 405 more convenient, improving the operation and maintenance efficiency of the equipment.

[0026] Working principle: During operation, the guide wheel assembly 2 slides along the guide rail 1, driving the moving platform 3 to lift and lower the goods, and the cleaning mechanism 4 on the support platform 6 moves synchronously. The cleaning plate 405 is in close contact with the inner wall of the guide rail 1 with an isosceles triangular structure. During the lifting process, it scrapes and cleans the dust, debris and small impurities on the surface of the guide rail 1 in both directions. The falling dust, debris and small impurities are sucked in and collected by the inverted trapezoidal connection port 407 of the dust collection box 402 through the through groove to avoid secondary pollution. The rollers 406 on the inner wall of the moving plate 401 help reduce friction and ensure that the cleaning mechanism 4 moves smoothly.

[0027] The mounting component 404 securely fixes the vacuum box 402 to the support platform 6 through the insertion and engagement of the connecting plate 4041 and the limiting screw 4043, ensuring synchronous lifting and lowering. When the vacuum box 402 needs to be disassembled, the limiting screw 4043 is turned to disengage it from the inner wall of the connecting plate 4041, and then it can be taken out upwards. At the same time, the high-definition camera 4032 of the monitoring component 403 captures the cleaning status of the guide rail 1 and the running status of the guide wheel assembly 2 in real time, and the image is transmitted to the control center for remote monitoring. When the cleaning plate 405 needs to be replaced, the bolt 503 of the disassembly mechanism 5 is unscrewed and the mounting column 501 is pulled out for quick disassembly and assembly without complicated tools.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
