Description

Technical Field

[0001] This utility model relates to a handling device, for example, for moving goods in a warehousing system. Background Technology

[0002] As warehousing systems rapidly evolve towards intelligence and high density, the performance boundaries of material handling equipment, as the core execution unit, are being continuously expanded. Traditional material handling equipment generally relies on hydraulic transmission mechanisms, which can meet basic load requirements, but the large hydraulic pump stations and oil tanks severely restrict the miniaturization of the equipment. Moreover, oil leakage not only pollutes the environment but also directly affects the stability of equipment operation, making it difficult to meet the dual requirements of compactness and reliability in modern warehousing.

[0003] To overcome the limitations of hydraulic transmission, mechanical reversing handling equipment has emerged in existing technologies. This equipment replaces the hydraulic cylinder system with a dual lifting assembly, which fundamentally solves the risk of oil leakage. However, the two lifting structures and the chain drive mechanism that drives the movement must be integrated into the equipment base plate, resulting in a complex overall layout and increased assembly difficulty. At the same time, the inherent defects of chain drive, such as low transmission efficiency and easy loosening after long-term operation, have not yet been overcome, which increases the frequency of later maintenance and limits the operating accuracy and response speed of the equipment.

[0004] To address the shortcomings of chain drive mechanisms, existing technology provides a handling device with a full gearbox drive structure, which optimizes the amount of power, makes the structure more compact, and improves overall performance and stability.

[0005] However, in the aforementioned handling equipment that uses a full gearbox transmission structure, the gearbox covers almost the entire side of the handling equipment, making it inconvenient to adjust the size of the equipment according to the condition of the goods. Utility Model Content

[0006] In view of the above problems, the purpose of this utility model is to provide a handling device that is easy to adjust the size of the equipment.

[0007] To achieve the above objectives, the handling device of this utility model includes a first direction traveling mechanism for causing the handling device to travel along a first direction. The first direction traveling mechanism includes a first direction drive shaft and two first direction wheel sets symmetrically arranged at both ends of the first direction drive shaft. Each first direction wheel set is provided with a set of first direction drive wheels and a set of first direction driven wheels that rotate with the rotation of the first direction drive wheels. A first direction drive gearbox connected to the first direction drive shaft and driving the first direction drive wheels to rotate is installed on the inner side of the first direction drive wheels. The first direction driven wheels are not connected to the first direction drive gearbox. In the first direction, the first direction drive gearbox extends on the inner side of the first direction drive wheels but does not extend to the inner side of the first direction driven wheels.

[0008] According to the handling device of this utility model, since the driven wheel in the first direction is not connected to the drive gearbox in the first direction, and the drive gearbox in the first direction does not extend to the inside of the driven wheel in the first direction, the drive gearbox in the first direction does not cover the entire side of the handling device, and the size of the device can be easily adjusted in the first direction according to the condition of the goods.

[0009] Preferably, the conveying device further includes a second-direction traveling mechanism for causing the conveying device to travel along a second direction perpendicular to the first direction. The second-direction traveling mechanism includes a second-direction drive shaft and two second-direction wheel sets symmetrically arranged at both ends of the second-direction drive shaft. Each second-direction wheel set is provided with a set of second-direction drive wheels and a set of second-direction driven wheels that rotate with the rotation of the second-direction drive wheels. A second-direction drive gearbox connected to the second-direction drive shaft and driving the second-direction drive wheels to rotate is installed on the inner side of the second-direction drive wheels. The second-direction driven wheels are not connected to the second-direction drive gearbox. In the second direction, the second-direction drive gearbox extends on the inner side of the second-direction drive wheels but does not extend to the inner side of the second-direction driven wheels.

[0010] According to the present invention, since the driven wheel in the second direction is not connected to the drive gearbox in the second direction, and the drive gearbox in the second direction does not extend to the inside of the driven wheel in the second direction, the drive gearbox in the second direction does not cover the entire side of the conveying device, thus allowing for convenient adjustment of the device size in the second direction according to the condition of the goods.

[0011] Preferably, the second directional traveling mechanism further includes: a second directional main bearing that supports both ends of the second directional drive shaft; and a second directional auxiliary bearing that further supports the second directional drive shaft on the inner side of each of the second directional main bearings.

[0012] According to the present invention, the handling equipment is provided with an additional bearing in the second direction on the basis of the main bearing in the second direction, which can significantly improve rigidity, stability and load-bearing capacity, while optimizing the force distribution.

[0013] Preferably, the second direction traveling mechanism further includes a second direction driving wheel housing for housing a set of second direction driving wheels. In the second direction driving wheel housing, a second direction driving gearbox, a second direction auxiliary bearing, and a second direction main bearing are sequentially housed from the inside in the first direction.

[0014] According to the present invention, since the second direction drive gearbox, the second direction auxiliary bearing, and the second direction main bearing are sequentially housed in the second direction drive wheel housing, the structure of the transport device can be made compact in the first direction.

[0015] Preferably, the second directional drive gearbox is housed entirely inside the housing of the second directional drive wheel.

[0016] According to the present invention, since the second direction drive gearbox is housed inside the housing of the second direction drive wheel, the size of the equipment can be adjusted more conveniently in the second direction according to the condition of the goods.

[0017] Preferably, the second directional traveling mechanism further includes a second directional driven wheel housing for housing a set of second directional driven wheels.

[0018] According to the present invention, since the second-direction driven wheel is housed inside the second-direction driven wheel housing, the size of the equipment can be adjusted more conveniently in the second direction according to the condition of the goods.

[0019] Preferably, the first directional drive shaft and the second directional drive shaft are driven by the same travel drive mechanism.

[0020] According to the present invention, since the first direction drive shaft and the second direction drive shaft are driven by the same traveling drive mechanism, the internal space of the handling equipment can be saved, making the handling equipment more compact.

[0021] Preferably, the conveying device further includes a lifting drive mechanism for switching between travel in the first direction and travel in the second direction. In the first direction, the lifting drive mechanism is connected to two opposing lifting drive gearboxes via a lifting drive shaft.

[0022] According to the present invention, the lifting drive mechanism connects two opposing lifting drive gearboxes through a lifting drive shaft, thereby enabling balanced force distribution and smooth switching of the travel state of the handling equipment.

[0023] Preferably, in the first direction, the first direction drive gearbox extends to a position closer to the first direction driven wheel than the midpoint between the first direction drive wheel and the first direction driven wheel.

[0024] According to the handling device of this utility model, since the first direction drive gearbox extends to a position closer to the first direction driven wheel than the middle position between the first direction drive wheel and the first direction driven wheel, the first direction drive gearbox can be conveniently used to connect the first direction drive shaft and the first direction drive wheel.

[0025] Preferably, in the first direction, the first direction drive wheel is located on one side of the first direction drive gearbox, and the first direction drive shaft is located on the other side of the first direction drive gearbox.

[0026] According to the present invention, the handling device utilizes a first direction drive gearbox to connect the first direction drive shaft and the first direction drive wheel, with the first direction drive shaft and the first direction drive wheel located at both ends of the first direction drive gearbox. Therefore, the handling device can be miniaturized in the second direction. Attached Figure Description

Figure 8 This is a cross-sectional view showing the structure of the second-direction traveling mechanism 103 of the conveying device 100 according to an embodiment of the present invention.

[0063] (Overall structure of handling equipment 100)

[0064] The following mainly refers to Figures 1 to 3 The overall structure of the handling equipment 100 according to the present invention will be described.

[0065] like Figure 1As shown, the handling device 100 of this embodiment is generally formed as a flat cuboid structure, including a housing 101, on which goods are loaded. The handling device 100 of this embodiment can travel along mutually orthogonal length directions (X-direction) and width directions (Y-direction). The X-direction corresponds to the first direction in this application, and the Y-direction corresponds to the second direction in this application. The Z-direction is a vertical direction orthogonal to both the X and Y directions.

[0066] like Figures 2-3 As shown, the conveying device 100 of this utility model includes: an X-direction traveling mechanism 102 for causing the conveying device 100 to travel in the X direction; a Y-direction traveling mechanism 103 for causing the conveying device 100 to travel in the Y direction; and a lifting drive mechanism 104 for switching between traveling in the X direction and traveling in the Y direction.

[0067] The following mainly refers to Figures 2 to 8 The structure of the X-direction traveling mechanism 102, the Y-direction traveling mechanism 103, and the lifting drive mechanism 104 of the handling equipment 100 according to the present invention will be described.

[0068] (X-direction traveling mechanism 102)

[0069] The X-direction traveling mechanism 102 includes an X-direction drive shaft 1021 and two X-direction wheel sets 1022 symmetrically arranged at both ends of the X-direction drive shaft 1021. Each X-direction wheel set 1022 includes a set of X-direction drive wheels 1022a and a set of X-direction driven wheels 1022b that rotate with the rotation of the X-direction drive wheels 1022a.

[0070] An X-direction drive gearbox 1023 is installed on the inner side of the X-direction drive wheel 1022a and is connected to the X-direction drive shaft 1021 to drive the X-direction drive wheel 1022a to rotate. The X-direction driven wheel 1022b is not connected to the X-direction drive gearbox 1023.

[0071] In the X direction, the X-direction drive gearbox 1023 extends inside the X-direction drive wheel 1021, but does not extend to the inside of the X-direction driven wheel 1022b.

[0072] In this embodiment, in the X direction, the X-direction drive gearbox 1023 extends to a position closer to the X-direction driven wheel 1022b than the midpoint between the X-direction drive wheel 1022a and the X-direction driven wheel 1022b.

[0073] Furthermore, in the X direction, the X-direction drive wheel 1022a is located on one side of the X-direction drive gearbox 1023, and the X-direction drive shaft 1021 is located on the other side of the X-direction drive gearbox 1023.

[0074] That is, in the X direction, only the X-direction drive shaft 1021 has power, while the X-direction driven wheel 1022b does not have power.

[0075] Therefore, according to the present invention, since the driven wheel 1022b in the X direction is not connected to the drive gearbox 1023 in the X direction, and the drive gearbox 1023 in the X direction does not extend to the inner side of the driven wheel 1022b in the X direction, the drive gearbox 1023 in the X direction does not cover the entire side of the transport device 100, and the size of the device can be easily adjusted in the X direction according to the condition of the goods.

[0076] Furthermore, according to the handling device 100 of this utility model, since the X-direction drive gearbox 1023 extends to a position closer to the X-direction driven wheel 1022b than the middle position between the X-direction drive wheel 1022a and the X-direction driven wheel 1022b, the X-direction drive gearbox 1023 can be conveniently used to connect the X-direction drive shaft 1021 and the X-direction drive wheel 1022a.

[0077] According to the present invention, the handling device 100 is miniaturized in the Y direction because the X-direction drive shaft 1021 and the X-direction drive wheel 1022a are connected by the X-direction drive gearbox 1023, and the X-direction drive shaft 1021 and the X-direction drive wheel 1022a are located at both ends of the X-direction drive gearbox 1023.

[0078] (Y-direction traveling mechanism 103)

[0079] The Y-direction traveling mechanism 103 includes a Y-direction drive shaft 1031 and two Y-direction wheel sets 1032 symmetrically arranged at both ends of the Y-direction drive shaft 1031. Each Y-direction wheel set 1032 includes a set of Y-direction drive wheels 1032a and a set of Y-direction driven wheels 1032b that rotate with the rotation of the Y-direction drive wheels 1032a.

[0080] A Y-direction drive gearbox 1033 is installed on the inner side of the Y-direction drive wheel 1032a and is connected to the Y-direction drive shaft 1031 to drive the Y-direction drive wheel 1032a to rotate. The Y-direction driven wheel 1032b is not connected to the Y-direction drive gearbox 1033.

[0081] In the Y direction, the Y-direction drive gearbox 1033 extends inside the Y-direction drive wheel 1031, but does not extend to the inside of the Y-direction driven wheel 1032b.

[0082] That is, in the Y direction, only the Y-direction drive wheel 1031 has power, while the Y-direction driven wheel 1032b does not have power.

[0083] Therefore, according to the present invention, since the driven wheel 1032b in the Y direction is not connected to the drive gearbox 1031 in the Y direction, and the drive gearbox 1031 in the Y direction does not extend to the inside of the driven wheel 1032b in the Y direction, the drive gearbox 1031 in the Y direction does not cover the entire side of the conveying device 100, and the size of the device can be easily adjusted in the Y direction according to the condition of the goods.

[0084] like Figure 8 As shown, the Y-direction traveling mechanism 103 further includes: Y-direction main bearings 1034 that support both ends of the Y-direction drive shaft 1031; Y-direction auxiliary bearings 1035 that further support the Y-direction drive shaft 1031 inside each Y-direction main bearing 1034; Y-direction drive wheel housing 1036 that houses a set of Y-direction drive wheels 1032a; and Y-direction driven wheel housing 1037 that houses a set of Y-direction driven wheels 1032b.

[0085] In the Y-direction drive wheel housing 1036, in the X-direction, from the inside, are sequentially housed the Y-direction drive gearbox 1033, the Y-direction auxiliary bearing 1035, and the Y-direction main bearing 1034. The Y-direction drive gearbox 1033 is entirely housed inside the Y-direction drive wheel housing 1036.

[0086] Therefore, the handling equipment 100 according to this utility model, since an additional bearing 1035 in the Y direction is provided on the basis of the main bearing 1034 in the Y direction, can significantly improve rigidity, stability and load-bearing capacity, while optimizing the force distribution.

[0087] According to the present invention, since the Y-direction drive gearbox 1033, the Y-direction auxiliary bearing 1035 and the Y-direction main bearing 1034 are sequentially housed in the Y-direction drive wheel housing 1036, the structure of the transport device 100 can be made compact in the X direction.

[0088] According to the present invention, since the Y-direction drive gearbox 1033 is housed inside the Y-direction drive wheel housing 1036, the size of the equipment can be adjusted more conveniently in the Y direction according to the condition of the goods.

[0089] According to the present invention, since the Y-direction driven wheel 1032b is housed inside the Y-direction driven wheel housing 1037, the size of the equipment can be adjusted more conveniently in the Y direction according to the condition of the goods.

[0090] In this embodiment, both the X-direction drive shaft 1021 and the Y-direction drive shaft 1031 are driven by the same traveling drive mechanism (traveling motor 107 and traveling reducer 108), that is, driven by the traveling motor 107 via the traveling reducer 108. This saves internal space in the handling equipment 100, making it more compact. Of course, the X-direction drive shaft 1021 and the Y-direction drive shaft 1031 can also be driven by different traveling drive mechanisms.

[0091] (Lifting drive mechanism 104)

[0092] The running states of the X-direction wheel set 1022 and the Y-direction wheel set 1032 are switched by the lifting drive mechanism 104. In this embodiment, in the X direction, the lifting drive mechanism 104 connects two opposing lifting drive gearboxes 1042 via a lifting drive shaft 1041. The lifting drive shaft 1041 is driven by a lifting motor 105 via a lifting reducer 106.

[0093] According to the present invention, the handling device 100 has a lifting drive mechanism 104 that connects two opposing lifting drive gearboxes 1042 via a lifting drive shaft 1041. Therefore, the force is balanced, and the running state of the handling device 100 can be switched smoothly.

[0094] (Modified example)

[0095] In this embodiment, both the gearboxes in the X and Y directions are configured as half-gearboxes (i.e., only one gear set is driven, and the other gear set is a driven gear set). However, as long as at least one gearbox in the X and Y directions is configured as a half-gearbox, the other gearbox can also be configured as a full gearbox (i.e., the gearbox drives both gear sets simultaneously).

[0096] In this embodiment, the structures of the X-direction traveling mechanism and the Y-direction traveling mechanism are different, but the structures of the X-direction traveling mechanism and the Y-direction traveling mechanism can also be set to be the same, which can be any one of the structures of the X-direction traveling mechanism and the Y-direction traveling mechanism in this embodiment.

[0097] In this embodiment, each wheel set includes two running wheels, but the number of running wheels in each wheel set is not limited and can be set according to actual requirements.

[0098] Although the structure and working principle of this utility model have been described above in conjunction with preferred embodiments, those skilled in the art should recognize that the above examples are merely illustrative and should not be construed as limiting the utility model. Therefore, modifications and variations can be made to this utility model within the spirit and scope of the claims, and all such modifications and variations will fall within the scope claimed by the claims of this utility model.
