Description

Technical Field

[0001] The utility model relates to the technical field of shuttle vehicles, in particular to a reversing structure of a four-way shuttle vehicle with buffering capability. Background Art

[0002] Warehousing is the storage and custody of goods and articles in warehouses. "Warehouse" is a general term for buildings and sites for storing, keeping and storing articles. It can be a house building, cave, large container or a specific site. Traditional warehousing refers to the use of warehouses to carry out the warehousing, storage and outbound activities of various materials and related facilities. Existing warehousing refers to the addition of in-warehouse processing, sorting, in-warehouse packaging and other links on the basis of traditional warehousing. Warehousing is one of the important links in production and manufacturing and commodity circulation, and it is also an important link in logistics activities. In the warehousing business, in order to consider economic benefits, it will be stored in the form of stacking. Furthermore, after the site is restricted, it can still provide efficient warehousing services.

[0003] As the amount of goods stored increases, the number of shelves placed increases. As a result, the shelf aisle space makes it difficult for forklifts to move flexibly in the aisle. In addition, due to the limited shelf aisle space, forklifts will occasionally collide. In the prior art, a shuttle car is used to solve the above technical problems. The shuttle car can use a reversing structure to reverse the shuttle car under the drive of the motor gear.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figures 1 to 8 As shown, the embodiment of the utility model provides a four-way shuttle reversing structure with buffering capability, comprising:

[0030] A vehicle frame 1000, a set of first moving wheels 2000 are arranged oppositely at two ends of the vehicle frame 1000, and a set of second moving wheels 3000 are arranged oppositely at the other two ends of the vehicle frame 1000, and the second moving wheels 3000 are arranged at a certain angle to the first moving wheels 2000;

[0031] The reversing device 4000 includes a cam follower 4100 and a cam 4200. The cam follower 4100 is used to lift the second moving wheel 3000 when ascending, and to lower the second moving wheel 3000 when descending;

[0032] A buffer component 4300 is disposed on the cam 4200, and the cam follower 4100 is connected to the cam 4200 through the buffer component 4300;

[0033] The controller is connected to the reversing device 4000 and is used to control the action of the reversing device 4000 .

[0034] The overall structure of the four-way shuttle in this embodiment is reasonably designed and compact. Specifically, the frame 1000 uses the cam follower 4100 in the reversing device 4000 to lift and lower the second moving wheel 3000, and the cam 4200 drives the cam follower 4100. The structure is reasonably designed, the production cost is low, and the subsequent maintenance and replacement are convenient.

[0035] At the same time, the cam follower 4100 is connected to the cam 4200 through the buffer component 4300, so that the cam 4200 can be well buffered in the process of driving the cam follower 4100 to move. In addition, the space between the cam follower 4100 and the cam 4200 is fully utilized, the actual design size of the shuttle can be reduced, and the structure of the shuttle is further optimized. The shuttle reduces the space requirement for the use of space, thereby increasing the cargo storage space of the vertical warehouse.

[0036] The shuttle vehicle in this embodiment not only has a reasonable structural design, but also has an obvious buffering effect when performing lifting and lowering actions, so that fragile goods are better protected during transportation.

[0037] See also Figure 6 As shown, in some embodiments, the buffer component 4300 includes a buffer slide 4310, and buffer elastic members 4320 are connected on both sides of the buffer slide 4310, and the buffer slide 4310 and the buffer elastic member 4320 are also provided with a buffer pad 4330; at the same time, the cam follower 4100 includes a rotating wheel 4110, and a rotating wheel connecting rod 4120 is connected to the rotating wheel 4110, and the rotating wheel connecting rod 4120 is slidingly connected to the buffer slide 4310, and the two sides of the rotating wheel connecting rod 4120 are respectively connected to the buffer elastic members 4320 arranged at both ends of the buffer slide 4310.

[0038] The buffer component 4300 in this embodiment includes a buffer slide 4310, a buffer elastic member 4320 and a buffer pad 4330. The buffer elastic member 4320 is connected to both sides of the buffer slide 4310, and the buffer pad 4330 is arranged between the buffer elastic member 4320 and the buffer slide 4310. The two sides of the rotating wheel connecting rod 4120 of the cam follower 4100 are respectively connected to the buffer elastic members 4320 connected to both sides of the buffer slide 4310. When the rotating wheel connecting rod 4120 slides toward one side of the buffer slide 4310, the buffer elastic member 4320 on this side is compressed, thereby forming a reverse elastic force on the rotating wheel connecting rod 4120. At the same time, the buffer elastic member 4320 on the other side of the rotating wheel connecting rod 4120 is stretched, thereby ensuring the stability of the cam 4200 and the cam follower 4100 during the movement.

[0039] At the same time, when the rotating wheel connecting rod 4120 moves to the side of the buffer slide 4310 and contacts the buffer pad 4330, the buffer pad 4330 further buffers the rotating wheel connecting rod 4120, thereby further ensuring the stability of the cam 4200 and the cam follower 4100 during the movement, thereby realizing the protection of fragile goods when the shuttle is lifted and lowered.

[0040] See also Figure 4 and Figure 8 As shown, in some embodiments, the reversing device 4000 includes:

[0041] The lifting plate 4400 has one end slidably connected to the frame 1000 and the other end fixedly connected to the second moving wheel 3000. A slide groove 4410 is provided in the middle of the lifting plate 4400, and the rotating wheel 4110 is provided in the slide groove 4410.

[0042] The reversing guide rail 4500 is fixedly connected to the vehicle frame 1000 , and the lifting plate 4400 is slidably connected to the vehicle frame 1000 via the reversing guide rail 4500 .

[0043] In this embodiment, one end of the lifting plate 4400 is fixedly connected to the second moving wheel 3000, so that the second moving wheel 3000 is lifted when the lifting plate 4400 is lifted, and the second moving wheel 3000 is lowered when the lifting plate 4400 is lowered; moreover, the other end of the lifting plate 4400 is slidably connected to the frame 1000 through the reversing guide rail 4500, so that the lifting plate 4400 can stably move along the track of the reversing guide rail 4500. When the shuttle needs to change the direction of movement of the first moving wheel 2000 to the direction of movement of the second moving wheel 3000, the lifting plate 4400 is controlled to be lowered, so that the second moving wheel 3000 on the lifting plate 4400 contacts the ground, and at the same time, the frame 1000 is lifted relative to the lifting plate 4400, so that the first moving wheel 2000 on the frame 1000 is retracted, so that the shuttle can move in the direction of movement of the second moving wheel 3000.

[0044] Among them, a slide groove 4410 is provided in the middle of the lifting plate 4400, and a rotating wheel 4110 of the cam follower 4100 is provided in the slide groove 4410. The cam 4200 drives the cam follower 4100 to rotate and stay at a desired position, and the cam follower 4110 is provided in the slide groove 4410. Therefore, the lifting plate 4400 can be driven to move up and down by controlling the cam 4200, so as to achieve the purpose of adjusting the height of the lifting plate 4400. An elastic washer 4130 is provided on the rotating wheel 4110. When the cam 4200 drives the cam follower 4100 to rotate, the cam follower 4100 will move back and forth in the slide groove 4410. The elastic washer 4130 is used to buffer the rotating wheel 4110, so as to ensure the stability of the cam follower 4100 and the slide groove 4410 during the movement.

[0045] See also Figures 1 to 3 As shown, in some embodiments, the reversing device 4000 further includes:

[0046] The transmission rod component 4600 has two ends connected to the cams 4200 on the corresponding sides respectively;

[0047] A transmission component 4700, which is fixedly connected to the transmission rod component 4600;

[0048] A reversing drive 4800, which is used to drive a transmission component 4700;

[0049] In this embodiment, the two ends of the transmission rod component 4600 are respectively connected to the cams 4200 on the corresponding sides, and the transmission component 4700 is fixedly connected to the transmission rod component 4600. When the reversing drive 4800 drives the transmission component 4700 to rotate, the transmission component 4700 drives the transmission rod component 4600 to rotate, and then the transmission rod component 4600 drives the cams 4200 at both ends to rotate.

[0050] At the same time, the reversing drive 4800 is also equipped with a reducer according to actual needs. Since the reducer can increase the output torque of the reversing drive 4800, it can protect the reversing drive 4800 well.

[0051] See also Figure 7 As shown, in some embodiments, the transmission component 4700 includes:

[0052] The transmission teeth 4710 are provided in a group and are respectively fixed on the driving end of the reversing drive 4800 and the transmission rod component 4600;

[0053] a transmission chain 4720 connected to the two transmission teeth 4710;

[0054] In the reversing drive 4800 of this embodiment, since a speed reducer will be provided during actual use, the transmission teeth 4710 are fixed to the driving end of the reversing drive 4800 and the transmission rod component 4600, and the transmission chain 4720 is used to connect the two transmission teeth 4710, thereby facilitating the installation of the speed reducer and the reversing drive 4800.

[0055] At the same time, a connecting piece 4900 is provided in the middle of the transmission rod component 4600, and the connecting piece 4900 adopts an elastic coupling. Since the transmission rod component 4600 is subjected to a large driving force when the reversing drive 4800 drives the transmission rod component 4600 to rotate, an elastic coupling is connected in the middle of the transmission rod component 4600 to protect the transmission rod component 4600 from damage. The elastic coupling is used to reduce vibration and buffer the transmission rod component 4600.

[0056] In some embodiments, it also includes:

[0057] A first driving motor 5000, whose output end is connected to the first moving wheel 2000, and the controller is connected to the first driving motor 5000 to control the first driving motor 5000 to rotate;

[0058] The output end of the second driving motor 6000 is connected to the second moving wheel 3000 , and the controller is connected to the second driving motor 6000 to control the rotation of the second driving motor 6000 .

[0059] In the present embodiment, the driving end of the first driving motor 5000 is connected to the first moving wheel 2000, and the first driving motor 5000 is connected to a battery, which is fixed on the vehicle frame 1000 and connected to the first driving motor 5000 through a wire. Therefore, the battery can be set at a suitable position of the vehicle frame according to actual use, so as to avoid the installation position of the first driving motor 5000 being too crowded, thereby reasonably utilizing the space on the vehicle frame 1000.

[0060] In addition, a protective plate is provided on the vehicle frame 1000 to separate the cargo on the shuttle vehicle from the transmission structure, thereby ensuring the stability of the cargo during transportation.

[0061] The beneficial effects of the utility model are:

[0062] The cam follower is buffered by the buffer component on the cam, so that effective buffering can be achieved when the second moving wheel is lifted and lowered, thereby avoiding the problem that the fragile goods are easily damaged when the shuttle vehicle is lifted and lowered.
