Description

Technical Field

[0001] This utility model belongs to the field of logistics and warehousing automation equipment, specifically relating to a single-column material box stacker loading platform. Background Technology

[0002] A stacker crane is a specialized crane that uses forks or booms as lifting devices to grab, move, and stack unitized goods in warehouses, workshops, and other locations, or to retrieve and place unitized goods from high-rise racks. It is a type of warehousing equipment. Early stacker cranes consisted of a gantry (column) suspended from the trolley of a bridge crane, using the up-and-down movement of the forks on the column and the rotation of the column to move goods; these were commonly called bridge stacker cranes. Around 1960, aisle stacker cranes appeared in the United States. These cranes used ground guide rails to prevent tipping. Subsequently, with the development of computer control technology and automated storage and retrieval systems (AS / RS), stacker cranes have become increasingly widely used, with improved technical performance and greater heights. Today, stacker cranes can reach heights of up to 40 meters. In fact, if not limited by warehouse building structure and costs, stacker cranes could be even taller.

[0003] Chinese patent CN211004389U discloses a single-column stacker crane loading platform, comprising a loading platform frame and columns. The loading platform frame is an integral welded component, consisting of a horizontal frame, guide brackets, and bracket connecting parts. The bracket connecting parts include a neck plate and a shoulder plate; the neck plate is connected to the guide brackets, and the shoulder plate is connected to the horizontal frame. Guide columns are symmetrically arranged on two opposite sides of the columns, and the guide brackets are secured to the guide columns. Guide wheels are installed between the guide brackets and the guide columns. This design reduces the space occupied by the loading platform on the stacker crane, making it suitable for use on smaller stacker cranes.

[0004] The inventors discovered that in this application, the traction guide wheels are all fixed, so it is impossible to adjust the position of the traction guide wheels according to different situations. As a result, the traction guide wheels cannot fit the column better, leading to a decrease in overall stability and posing certain safety hazards.

[0005] Therefore, we studied and improved the existing structure and its shortcomings to provide a single-column stacker crane loading platform, in order to achieve a more practical purpose. Utility Model Content

[0029] Example 1, please refer to Figure 1 , Figure 2A single-column 5-bin stacker crane loading platform is applied to a column 5. The column 5 has symmetrically distributed and fixedly connected guide plates 10 on both sides. The stacker crane loading platform includes a U-shaped guide frame 4 wrapped around the outside of the column 5 and a loading plate fixed to the outside of the guide frame 4. The guide frame 4 is equipped with a traction wire rope assembly 1, and symmetrically distributed and reciprocally adjustable first guide wheels 2 are also provided on the guide frame 4. The first guide wheels 2 are rolled to the column 5. Multiple rolled second guide wheels 3 are provided on both sides of the guide plate 10, and the second guide wheels 3 are fixedly connected to the guide frame 4. The loading plate includes a crossbeam 7 and two horizontal tie rods 8. Both ends of the horizontal tie rods 8 are fixedly connected to the ends of the crossbeams 7, and the other end of the crossbeams 7 is fixedly connected to the guide frame 4. The traction wire rope assembly 1 is prior art, therefore this application will not describe it in detail.

[0030] The design of the single column 5 can improve the space utilization of the stacker crane's automated warehouse; the design of the crossbeam 7 and the horizontal tie rod 8 can effectively reduce the overall weight, thereby saving drive energy; the overall structure is simple, easy to process, and saves costs. At the same time, the adjustable design of the first guide wheel 2 can make the first guide wheel 2 fit well with the column 5, ensuring the stability of the overall up and down movement.

[0031] Please see Figure 3 In this embodiment, the first guide wheel 2 includes a guide wheel body 22 and an outer ring 21. The outer ring 21 is rotatably connected to the guide wheel body 22. A fixed shaft 23 is fixedly connected to the guide wheel body 22 at a non-central location. The fixed shaft 23 is rotatably mounted on the guide frame 4. The outer ring 21 is fitted against the column 5.

[0032] The first guide wheel 2 adopts an eccentric wheel design, which can realize the rolling connection between the first guide wheel 2 and the column 5, and also adjust the distance between the first guide wheel 2 and the column 5. The distance between the first guide wheel 2 and the column 5 can be adjusted by rotating the fixed shaft 23, so that the first guide wheel 2 can better fit the column 5.

[0033] Please see Figure 1 , Figure 3In this embodiment, the upper end of the guide frame 4 is provided with a U-shaped top stiffener plate 11 that is fixedly connected. The traction wire rope group 1 is fixedly installed on the top stiffener plate 11. The top stiffener plate 11 is provided with symmetrically distributed and fixedly connected first mounting plates 12. The first mounting plate 12 is provided with a second mounting plate 121. The second mounting plate 121 and the first mounting plate 12 are fixedly connected by bolts. The first mounting plate 12 and the second mounting plate 121 are both provided with corresponding semi-circular adjustment grooves. The fixed shaft 23 is rotatably arranged in the adjustment groove.

[0034] In this embodiment, the first mounting plate 12 and the second mounting plate 121 are used to press and fix the fixed shaft 23 by bolts. The fixed shaft 23 is provided with a prism rod 24 on the outside of the fixed shaft 23 for fixed connection and to facilitate the rotation of the fixed shaft 23.

[0035] The fixed shaft 23 can be fixed and limited by tightening the bolts. This design is simpler and less expensive. When adjusting, simply loosen the bolts to release the fixation of the fixed shaft 23, and then rotate the fixed shaft 23 to adjust the distance between the first guide wheel 2 and the column 5. After adjustment, it can be fixed again by bolts. The addition of the prism rod 24 makes the adjustment of the fixed shaft 23 more convenient and labor-saving.

[0036] In this embodiment, the crossbeam 7 is provided with symmetrically distributed and fixedly connected fork mounting plates 9.

[0037] Please see Figure 1 In this embodiment, the bottom of the flow guide frame 4 is provided with a fixedly connected bottom stiffener plate 13, the bottom stiffener plate 13 is fixedly connected to the end of the corresponding crossbeam 7, and a side reinforcing rib 6 is also provided between the bottom stiffener plate 13 and the flow guide frame 4.

[0038] The combination of the bottom stiffener 13 and the side stiffener 6 can effectively improve the stability of the connection between the cargo plate and the guide frame 4.

[0039] In this embodiment, the guide plate 10 is also provided with fall arresters on both sides to prevent it from falling. The fall arresters are fixedly connected to the guide frame 4. The fall arresters are the same as those used in the existing elevator industry. Therefore, the specific structure will not be described in detail. The addition of the fall arresters can effectively limit the flow frame 4 in the event of a sudden fall, thereby improving the overall safety.

[0040] Example 2
