Description

Technical Field

[0001] This utility model relates to a stacker crane, specifically a trackless stacker crane with a lifting roller line. Background Technology

[0002] Stacker cranes are used for palletizing goods and are efficient. Currently, stacker cranes have the functions of lateral movement and lifting, transporting goods from designated locations to designated locations. However, when stacking, goods need to be placed according to the height of the stack, which requires the assistance of forklifts. In some small spaces, stacker cranes combined with forklifts are not practical, as there is not enough space for forklifts to move around, resulting in low stacking efficiency. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides a trackless stacker with lifting rollers. This utility model has partial translation, lifting and longitudinal conveying functions, which can directly deliver goods to the stack from a high position without the need for forklift assistance, thus improving efficiency.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: a trackless stacker with lifting rollers, comprising a frame, a lifting drive component, and a lifting roller assembly;

[0005] The frame includes two uprights, a top crossbeam, and a bottom traveling assembly. The two uprights are located on the bottom traveling assembly, and the crossbeam is located on top of the two uprights.

[0006] The lifting drive component includes a drive motor, two steel wire ropes, and a transmission wheel assembly. The transmission wheel assembly is mounted on the crossbeam, and the drive motor is mounted on one of the columns. The steel wire ropes are driven by the drive motor and laid on the transmission wheel assembly before being connected to the lifting drum assembly.

[0007] The lifting roller assembly includes two side plates and a base plate. The two side plates are respectively connected to the two steel wire ropes. The two side plates also contact the two columns through roller sets. The base plate is installed on the two side plates and has rollers installed on it. The rollers are connected to a roller motor.

[0008] The drive motor is equipped with two take-up and unwinding reels. The transmission wheel set includes wheel one, wheel two, and wheel three. Wheel one is installed on one side of the crossbeam, and wheel two and wheel three are installed on the other side of the crossbeam. One side plate is provided with connector one, and the other side plate is provided with connector two. One end of one wire rope is wound on one of the take-up and unwinding reels, and the other end is laid on wheel one and fixed to connector one. One end of another wire rope is wound on the other take-up and unwinding reel, and the other end is laid on wheel two and wheel three and fixed to connector two.

[0009] The base plate is equipped with two fixing plates, and the two ends of the roller are respectively installed on the two fixing plates. The roller motor is fixed to the base plate and is driven by the roller. The rolling direction of the roller is perpendicular to the walking direction of the bottom walking assembly.

[0010] The roller assembly includes two side rollers and one side roller. The two side rollers contact the two sides of the column respectively, and the one side roller contacts the inner surface of the column.

[0011] The columns are also equipped with reinforcing bars.

[0026] Example:

[0027] Figure 1 This is a front view of a trackless stacker crane with lifting rollers. Figure 2 yes Figure 1 A three-dimensional schematic diagram, including frame 1, lifting drive component 2, and lifting roller assembly 3;

[0028] The frame 1 includes two uprights 12, a top crossbeam 11, and a bottom walking assembly 13. The two uprights 12 are located on the bottom walking assembly 13, and the crossbeam 11 is located on top of the two uprights 12.

[0029] Specifically, the bottom walking assembly 13 includes a frame with walking wheels and a bottom rail. The walking wheels move along the rail, and the walking wheels work with a drive motor to move the lifting roller assembly 3 laterally to a designated position. This invention only uses a bottom rail, eliminating the need for a top rail and saving space above, without affecting the operation of other equipment.

[0030] The lifting drive component 2 includes a drive motor 21, two steel wire ropes 26, and a transmission wheel set. The transmission wheel set is mounted on the crossbeam 11, the drive motor 21 is mounted on one of the columns 12, and the steel wire ropes 26 are driven by the drive motor 21 and laid on the transmission wheel set before being connected to the lifting roller assembly 3.

[0031] Specifically, the drive motor 21 is equipped with two take-up and unwinding reels 22, and the transmission wheel set includes a first wheel 23, a second wheel 24, and a third wheel 25. The first wheel 23 is installed on one side of the crossbeam 11, and the second wheel 24 and the third wheel 25 are installed on the other side of the crossbeam 11. One side plate 31 is provided with a first connector 36, and the other side plate 31 is provided with a second connector 39. One end of one wire rope 26 is wound on one of the take-up and unwinding reels 22, and the other end is laid on the first wheel 23 and fixed to the first connector 36. One end of another wire rope 26 is wound on the other take-up and unwinding reel 22, and the other end is laid on the second wheel 24 and the third wheel 25 and fixed to the second connector 39.

[0032] This utility model utilizes two steel wire ropes, one long and one short, to pull the lifting roller assembly 3 at both ends to achieve lifting. Furthermore, the connection of the steel wire ropes at the lifting roller assembly 3 is a diagonal structure to maintain a balanced state and prevent unbalanced lifting from causing the goods to scatter.

[0033] Among them, such as Figure 3 As shown, the lifting roller assembly 3 includes two side plates 31 and a base plate 32. The two side plates 31 are respectively connected to the two steel wire ropes 26. The two side plates 31 are also respectively in contact with the two columns 12 through roller groups. The base plate 32 is installed on the two side plates 31. The base plate 32 is equipped with a roller 34. The roller 34 is connected to 40.

[0034] Specifically, the base plate 32 is equipped with two fixing plates 33, and the two ends of the roller 34 are respectively installed on the two fixing plates 33. The roller motor 35 is fixed to the base plate 32 and driven by the roller 34. The rolling direction of the roller 34 is perpendicular to the traveling direction of the bottom traveling assembly 13. This invention enables the roller 34 to transport goods longitudinally and, after being raised to a suitable position, actively delivers the goods to a designated location for palletizing. The roller 34 uses active power transmission, which can deliver the goods, resulting in better palletizing effect without the need for a forklift.

[0035] The roller assembly includes two side rollers 37 and one side roller 38. The two side rollers 37 respectively contact the two sides of the column 12, and the one side roller 38 contacts the inner surface of the column 12. This invention, by setting up the roller assembly, can reduce friction and ensure the verticality of the lifting motion, preventing the lifting roller assembly 3 from rising and falling steadily.

[0036] The column 12 is also equipped with a reinforcing rod 4.

[0037] The two side plates 31 are also provided with reinforcing beams 5.

[0038] Working principle:

[0039] The bottom walking assembly 13 moves the entire equipment to the receiving position. The drive motor 21 releases the wire rope to lower the lifting roller assembly 3 to the specified height. The roller motor 35 controls the roller 34 to run and receive the goods. The bottom walking assembly 13 moves to the stacking position. The lifting roller assembly 3 rises to the specified height. The roller motor 35 controls the roller 34 to run and deliver the goods.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
