Description

Technical Field

[0001] This utility model relates to the field of stacker technology, and in particular to a mobile stacker. Background Technology

[0002] A stacker crane is a machine used to store goods in a storage yard. In domestic and international ports, material storage and transshipment generally take the form of open-air storage yards, making stacker cranes crucial storage yard equipment. Its main function is to stack goods unloaded by unloaders onto the storage yard, facilitating retrieving operations by reclaimers.

[0003] Existing stackers cannot meet the needs of unloading at multiple angles. Even if some stackers can unload at multiple angles, it is inconvenient to move the stacker to the designated unloading and stacking position, and it is also inconvenient to adjust the height and angle of stacking and unloading.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0031] See Figure 1 , Figure 3 and Figure 6Furthermore, the crossarm 1 of this invention has two sets of fixing plates 20 inside one end near the traveling frame 15.

[0032] See Figure 8 and Figure 9 Furthermore, the cross arm 1 of this utility model is provided with a second fixing block 27 near the bottom of the connecting plate 18.

The connecting shaft 39 and the auxiliary roller 38 are located on the... Inside the telescopic arm 8, the auxiliary rollers 38 are located at both ends of the connecting shaft 39. The auxiliary rollers 38 are slidably connected to the slide rail 37. The drive motor 33 drives the rotating shaft 34 to rotate. The rotation of the rotating shaft 34 drives the gear 35 to rotate. Since the gear 35 and the rack 36 mesh, and the rack 36 and the slide rail 37 are both located on the folding arm 2, the rotation of the gear 35 will drive the telescopic arm 8 to move. At the same time, the slide rail 37, the auxiliary rollers 38 and the connecting shaft 39 provide stable support for the movement of the telescopic arm 8.

[0035] See Figure 1 , Figure 5 and Figure 8 Finally, the support frame 9 of this utility model has an internal cavity, and a movable frame 40 that is slidably connected to the folding arm 2 is provided in the cavity. The support frame 9 has a fourth hydraulic cylinder 41 on both sides, and a fourth telescopic rod 42 is provided at the output end of the fourth hydraulic cylinder 41. The end of the fourth telescopic rod 42 is connected to the movable frame 40. By moving the fourth telescopic rod 42 and the movable frame 40 through the fourth hydraulic cylinder 41, the angle and height of the folding arm 2 can be adjusted, thereby adapting to the needs of unloading and stacking materials at different angles and heights.

[0036] The working principle of this utility model:

[0037] First, the operator starts the travel motor 16 through the external control cabinet 3 to move the drive wheel 17 and the driven wheel 19. After moving to the designated position, the operator starts the first cylinder 21 through the external control cabinet 3 to move the first telescopic rod 22, so that the support base 23 contacts the ground. At this time, the drive wheel 17 is in a suspended state. Then, the operator starts the second cylinder 25 through the external control cabinet to move the second telescopic rod 26, so that the travel frame 15 on both sides of the horizontal arm 1 opens, and the position of the two sets of drive wheels 17 changes. After the position of the drive wheel 17 is adjusted, the operator can control the first cylinder 21 to retract the support base 23, so that the drive wheel 17 contacts the ground, which facilitates the subsequent control of the drive wheel 17 to move, realizing a circular motion with the rotating drum 6 as the center and the distance from the rotating drum 6 to the drive wheel 17 as the radius. After the position is determined, the travel motor 16 can be turned off, so that the horizontal arm 1 is stationary.

[0038] Secondly, the staff starts the drive motor 33 through the external control cabinet 3. The drive motor 33 drives the rotating shaft 34 to rotate. The rotation of the rotating shaft 34 drives the gear 35 to rotate. Since the gear 35 and the rack 36 mesh, and the rack 36 and the slide rail 37 are both located on the folding arm 2, the rotation of the gear 35 will drive the telescopic arm 8 to move. At the same time, the slide rail 37, the auxiliary roller 38 and the connecting shaft 39 provide stable support for the movement of the telescopic arm 8, so that the telescopic arm 8 is adjusted to the appropriate position.

[0039] Then, the staff starts the fourth hydraulic cylinder 41 through the external control cabinet 3. The fourth hydraulic cylinder 41 drives the fourth telescopic rod 42 and the moving frame 40 to move, which can adjust the angle of the folding arm 2 to adapt to the needs of leakage and material stacking at different heights.

[0040] Finally, materials are added to the feed inlet 5 by other external machines. At this time, the rotating motor 31 needs to be turned on. The rotating motor 31 drives the roller shaft 30 and the first active roller 11 to rotate, so that the belt on the folding arm 2 operates. At the same time, the electric roller is turned on, so that the belt on the telescopic arm 8 operates, thereby realizing the transportation of materials.

[0041] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
