[0044] The specific implementation of a four-way shuttle vehicle of the utility model is described in detail below with reference to the accompanying drawings.
[0045] See attached Figure 1 , 2 The left-right movement direction in the attached figure is the X direction, and the front-back movement direction is the Y direction. The X direction and the Y direction are only used to better understand the content of the patent, and are not intended to limit the scope of protection. The four-way shuttle vehicle includes a quadrilateral frame 1 and an X-direction walking system 2, a Y-direction walking system 3 and a reversing system 4 arranged on the frame 1. The X-direction walking system 2 drives the four-way shuttle vehicle to move in the X direction, and the Y-direction walking system 3 drives the four-way shuttle vehicle to move in the Y direction.
[0046] The frame 1 is a frame structure, including four frames 5 and a middle partition 6 to ensure the strength of the frame 1. The X-direction walking system 2 and the Y-direction walking system 3 are respectively arranged on the sides of the frame 1 to drive the four-way vehicle forward and backward in the X direction and the Y direction.
[0047] See attached Figure 3The X-direction walking system 2 includes an X-direction rotating shaft 7 arranged on the frame 1, an X-direction driving wheel 8 and an X-direction driven wheel 9 are arranged on both sides of the frame 1 in the X direction, the X-direction rotating shaft 7 is connected to the X-direction driving wheel 8 through a gear transmission, and an X-direction driving mechanism 10 is also arranged on the frame 1, and the X-direction driving mechanism 10 is connected to the X-direction rotating shaft 7 through a gear transmission to drive the X-direction rotating shaft 7 to rotate.
[0048] There are two X-direction driving wheels 8 on both sides of the frame 1, and X-direction gear boxes 12 are installed on 11 on both sides of the frame 1. The two ends of the X-direction rotating shaft 7 drive the two X-direction driving wheels 8 through the X-direction gear boxes 12 respectively. There are also two X-direction driven wheels 9, which are arranged on the rear side of the forward direction of the X-direction driving wheel 8. The X-direction driven wheels 9 are idle and are only used to support the balance of the frame 1. The X-direction gear box 12 symmetrically drives the two X-direction driving wheels 8, which can be achieved in two ways. One is to achieve forward and backward movement respectively by cooperating with the clutch mechanism of the two X-direction driving wheels 8, and the other is to achieve forward and backward movement of the two X-direction driving wheels 8 synchronously, which can be achieved by controlling the power output of the X-direction driving mechanism 10.
[0049] The X-direction driving mechanism 10 is an X-direction reduction motor 13, which is connected to the X-direction rotating shaft 7 through an X-direction gear reduction box 14. The X-direction reduction motor 13 is fixed on the partition 6, and an oil injection hole 15 is provided on the X-direction gear reduction box 14. The oil injection hole 15 is used to inject lubricating oil into the X-direction gear reduction box 14 to ensure smooth gear meshing and improve efficiency.
[0050] See attached Figure 4 , 5 The Y-direction walking system 3 includes a Y-direction rotating shaft 16 arranged on the frame 1, and a Y-direction driving wheel 17 and a Y-direction driven wheel 18 are arranged on both sides of the Y-direction of the frame 1. The Y-direction rotating shaft 16 is connected to the Y-direction driving wheel 17 through a gear transmission. A Y-direction driving mechanism 19 is also arranged on the frame 1, and the Y-direction driving mechanism 19 is connected to the Y-direction rotating shaft 16 through a gear transmission to drive the Y-direction rotating shaft 16 to rotate.
[0051] The Y-direction walking system 3 and the X-direction walking system 2 are independent of each other. The reversing system 4 drives the Y-direction walking system 3 to rise and fall as a whole. When the Y-direction walking system 3 rises as a whole, the Y-direction walking system 3 drives the four-way shuttle to move in the Y direction. When the Y-direction walking system 3 falls as a whole, the X-direction walking system 2 drives the four-way shuttle to move in the X direction.
[0052] The Y-direction driving mechanism 19 is a Y-direction reduction motor 20, which is connected to the Y-direction rotating shaft 16 through a Y-direction gear reduction box 21. The Y-direction reduction motor 20 is supported by the Y-direction rotating shaft 16, and an oil injection hole 15 is provided on the Y-direction gear reduction box 21. The oil injection hole 15 is used to inject lubricating oil into the Y-direction gear reduction box 21 to ensure smooth gear meshing and improve efficiency.
[0053] Y-direction lifting plates 22 are arranged on both sides of the frame 1, the Y-direction driving wheels 17 and the Y-direction driven wheels 18 are arranged on the Y-direction lifting plates 22, the reversing system 4 is fixedly arranged on the frame 1, and the reversing system 4 drives the Y-direction lifting plates 22 to rise and fall, so that the Y-direction walking system 3 can be lifted and lowered as a whole.
[0054] The Y-direction lifting plates 22 on both sides are driven to rise and fall relative to the frame 1 by the reversing system 4. When rising, the X-direction driving wheel 8 and the X-direction driven wheel 9 of the X-direction walking system 2 are located at the bottom and cooperate with the ground. When the Y-direction lifting plates 22 are lowered, the Y-direction driving wheel 17 and the Y-direction driven wheel 18 are located at the bottom and cooperate with the ground.
[0055] See attached Figure 6 The reversing system 4 includes a lifting transmission shaft 23 and a lifting driving mechanism 24 arranged in the frame 1. Lifting cam rods 25 are installed on both side plates of the frame 1 in the Y direction. Cam grooves (not shown in the figure) are arranged on the Y-direction lifting plate 22. The lifting driving mechanism 24 drives the lifting transmission shaft 23 to rotate, so that the Y-direction lifting plate 22 can be lifted up and down. Two lifting cam rods 25 are installed on both side plates of the frame 1 in the Y direction. The two lifting cam rods 25 move in opposite directions, and the Y-direction lifting plate 22 can be lifted and lowered at the same time.
[0056] The lifting drive mechanism 24 is a lifting reduction motor 26 , which is connected to the lifting transmission shaft 23 through a lifting gear reduction box, and the lifting transmission shaft 23 is connected to the lifting cam rod 25 through a lifting gear box.
[0057] A support plane is arranged above the entire frame 1 for fixing objects during work and for various operations in other logistics and transportation processes.
[0058] The X-direction driving wheel 8, the X-direction driven wheel 9, the Y-direction driving wheel 17, and the Y-direction driven wheel 18 are all equipped with tires on the wheel hubs to be suitable for the ground environment of the logistics warehouse. Since the X-direction transmission shaft and the Y-direction transmission shaft are transmitted in the form of gears, the interference of movement will be caused by processing errors and material deformation. Therefore, a universal coupling 27 is set on the X-direction transmission shaft or the Y-direction transmission shaft to offset its deformation deviation. The universal coupling 27 can also be set on both the X-direction transmission shaft and the Y-direction transmission shaft.
[0059] When the four-way shuttle is working, in the logistics warehouse, the control system controls the four-way shuttle to move in the X direction or the Y direction through the communication tool according to the instruction. When switching between the X direction and the Y direction, the reversing system 4 controls the Y-direction lifting plate 22 to rise or fall, so that the driving wheel and the driven wheel of the X direction contact the ground or the driving wheel 17 and the driven wheel of the Y direction contact the ground, and then drives the four-way shuttle forward and backward in the X direction or the Y direction through their respective driving mechanisms.
[0060] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
