[0002] With the rapid development of the logistics industry and the rising labor costs, how to reduce labor costs and improve the automation and intelligence of logistics systems is the focus of further development and optimization of the industry. The four-way shuttle is a frequently used vehicle in the current logistics automation process. The travel system of the four-way shuttle usually adopts multi-wheel drive travel, with wheels traveling in two directions. However, most of the four-way shuttles currently use two sets of drive systems to drive the wheels traveling in two directions respectively, and the structure is complicated. In addition, only one set of wheels has power at startup, the friction force at startup is small, and there is a certain risk of slipping at startup, which affects the normal travel of the four-way shuttle.

[0004] Technical solution: To solve the above problems, the utility model adopts a full-drive four-way shuttle vehicle for pallets, comprising a frame, a sub-track wheel system and a main track wheel system arranged on the frame, wherein the driving directions of the sub-track wheel system and the main track wheel system are perpendicular to each other, and further comprising a driving assembly installed in the frame, wherein a first sprocket shaft and a second sprocket shaft are connected to the driving assembly, the first sprocket shaft is connected to a first chain, and the first chain is connected to the sub-track wheel system to drive the sub-track wheel system to rotate; a second chain is also connected to the second sprocket shaft, the second chain is connected to a third sprocket shaft, and both ends of the third sprocket shaft are connected to the main track wheel system to drive the main track wheel system to rotate.

[0005] Furthermore, the driving assembly includes a motor and a reducer connected to the motor, and the first sprocket shaft and the second sprocket shaft are both connected to the reducer.

[0006] Furthermore, the first sprocket shaft axis is perpendicular to the output axis of the drive assembly, and the first chain axis is parallel to the output axis of the drive assembly.

[0007] Furthermore, the second chain axis is perpendicular to the output axis of the drive assembly, and the axes of the second sprocket shaft and the third sprocket shaft are parallel to the output axis of the drive assembly.

[0013] Figure 2 The utility model is a schematic diagram of the matching structure of the chain and the sub-track wheel of the pallet four-way shuttle. DETAILED DESCRIPTION

[0014] like Figure 1 As shown, a four-way shuttle vehicle for pallets with full drive in this embodiment includes a frame, a driving assembly mounted on the frame, and a sub-track wheel system and a mother-track wheel system mounted on the four sides of the frame. The sub-track wheel system is symmetrically mounted on both sides of the frame, and each side includes four sub-track wheels 5. The mother-track wheel system is mounted on both ends of the frame, and each end includes two mother-track wheels 11. The driving directions of the sub-track wheel system and the mother-track wheel system are perpendicular to each other. In this embodiment, the upper and lower frames are set up, and the sub-track wheel system and the mother-track wheel system can be reversed by moving the upper and lower frames up and down relative to each other. The technical means for the reversal are existing technologies and will not be repeated here.

[0015] The driving assembly includes a motor 1 and a bidirectional gearbox reducer 2 connected to the motor 1. The input end of the bidirectional gearbox reducer 2 is connected to the output shaft of the motor 1, and the output end of the bidirectional gearbox reducer 2 is a first sprocket shaft (3, 7) and a second sprocket shaft 6. The second sprocket shaft is perpendicular to the first sprocket shaft (3, 7), and the second sprocket shaft 6 is coaxial or parallel to the output shaft of the motor. The bidirectional gearbox reducer is a type of reducer device in the prior art, and the internal structure is not repeated here.

[0016] The ends of the first sprocket shaft (3, 7) are respectively connected to the two first chains 4, and the first chain 4 frame is installed with the side of the sub-track wheel system in parallel, and the first chain 4 is connected to the sub-track wheel system to drive the sub-track wheel system to rotate. Specifically, the two ends of the first sprocket shaft (3, 7) are respectively connected to the first driving sprocket 13, and each sub-track wheel is coaxially connected to a first driven sprocket 14, and each first driven sprocket 14 is connected to the first driving sprocket 13 through the first chain 4. The rotation of the first driving sprocket 13 drives all the first driven sprockets 14, that is, drives all the sub-track wheels 5 to rotate simultaneously.

[0017] The second sprocket shaft 6 is connected with a second chain (8, 12), and the second chain (8, 12) is connected with two third sprocket shafts 9 which are parallel to each other, the axis of the second chain is perpendicular to the output axis of the drive assembly, and the axis of the third sprocket shaft 9 is parallel to the output axis of the drive assembly. A telescopic coupling 10 is connected at both ends of each third sprocket shaft 9, and the telescopic coupling 10 is connected with the axle of the master wheel 11 to drive the master wheel 11 to rotate. Since the second chain (8, 12) drives the two third sprocket shafts 9 to rotate at the same time, all the master wheels 11 can rotate at the same time. The purpose of using the telescopic coupling 10 here is that, in this embodiment, the frame where the master wheel 11 is located moves up and down, while the motor and the reducer remain fixed, so the two ends of the telescopic coupling 10 can be adjusted to different heights and can still always maintain the output of power.

[0018] Since the bidirectional gearbox reducer 2 is characterized by being able to simultaneously drive the mutually perpendicular first sprocket shaft (3, 7) and the second sprocket shaft 6 to rotate simultaneously, the motor 1 can simultaneously drive the sub-track wheel train and the main track wheel train to travel.

[0019] No matter the utility model is traveling in the sub-track direction or the main track direction, the corresponding traveling wheels are powered, which increases the starting friction required for driving and effectively reduces the risk of starting slippage. Especially for the traveling tracks of frosted cold storage, the structural advantage is more obvious.
