[0002] During the entire logistics transportation process, items need to be sorted and transported many times, and the sorting process is completed at each transfer station. Due to the different delivery locations of the items, the items need to be classified and processed. If manual labor is used, it will inevitably fail to meet the requirements of high efficiency. Therefore, various equipment is currently used to realize automated sorting and transportation.

[0003] Suspended rail transport is a current mode of logistics sorting and transportation. Since the transport vehicle moves at a higher altitude, it can save a lot of space. After the items are sorted by intelligent sorting equipment, the suspended rail transport vehicle will transport the sorted items to the designated loading location, which can greatly improve the efficiency of logistics transit sorting.

[0004] In actual situations, sorting centers generally have multiple driving rails for transportation. There may be multiple transport vehicles on one driving rail for transportation in turn. Due to the uncertainty of the delivery area of ​​items, this leads to different transportation pressures on different driving rails, which easily leads to uneven distribution of transport vehicles. Due to the high frequency of suspended rail transportation of logistics, switching structures are rarely set on the driving rails for stability. If transport vehicles need to be deployed, manual disassembly and installation processes will be involved, resulting in inefficient track change processing. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] like Figure 1 As shown, a rail-changeable logistics suspended rail transport vehicle provided by an embodiment of the present invention includes a suspended platform 1, and a transport storage box 2 located at the bottom of the suspended platform 1, and also includes:

[0033] Two travel components 3, both of which are located at the top of the suspension platform 1 and are arranged at intervals, the travel components 3 include a lifting platform 301 rotatably connected to the suspension platform 1, a plurality of power unit boxes 302 are slidably arranged on the top of the lifting platform 301, the number of the power unit boxes 302 is an even number and is greater than or equal to four, the power unit boxes 302 can move along the width direction of the lifting platform 301 on the lifting platform 301, the output end of the power unit box 302 is located on one side thereof and is provided with a driving wheel 303, the driving wheel 303 on the top of the lifting platform 301 is symmetrically staggered about the lifting platform 301, and the lifting platform 301 is also provided with a sliding component 304 that enables the power unit box 302 to move laterally, such as Figure 2 As shown, when the lifting platform 301 drives the power unit box 302 to rise, the sliding assembly 304 is used to increase the distance between the driving wheels 303 located on different sides of the lifting platform 301. When the lifting platform 301 is in the initial state, the distance between the driving wheels 303 located on different sides of the lifting platform 301 is smaller than the width of the lifting platform 301, and the overall structural width of the power unit box 302 and its corresponding driving wheels 303 is smaller than the distance between the driving guide rails used by the transport vehicle, and the distance between the rotation centers of the two lifting platforms 301 is greater than the length of the lifting platform 301;

[0034] The track-changing control component 4 is located at the bottom of the suspension platform 1. When one of the travel components 3 is located in the driving guide rail, the track-changing control component 4 is used to drive the suspension platform 1 to rotate around the travel component 3;

[0035] The suspension component 5 is fixedly arranged at the bottom of the box body 401 and is used to connect the track change control component 4 with the transport storage box 2 at the bottom.

[0036] In one embodiment of the present invention, when the transport vehicle is in use, the movement of the overall structure is achieved through the travel component 3 on one side, and the storage box 2 is used to receive logistics goods. The characteristic is that the driving wheel 403 is driven to rotate by the driving member 402 by utilizing the uniform distribution of the travel guide rails in logistics. Since the travel component 3 on one side is restricted and cannot rotate by the travel guide rail, the overall structure of the suspension platform 1 will rotate, so that the other travel component 3 is turned to the other side, so that the travel component 3 corresponds to the position of the other travel guide rail, and the cooperation with the travel guide rail is achieved through the lifting platform 301 of the travel component 3. The travel component 3 that originally drives the transport vehicle to move is lowered and retracted under the action of the lifting platform 301, and the travel component 3 can be separated from the previous travel guide rail. The above structure can realize rapid switching between different travel guide rails, and even continuous switching.

[0037] In one embodiment of the present invention, a motor may be provided in the power unit box 302, and the motor drives the driving wheel 303 to rotate, and the driving wheel 303 cooperates with the driving guide rail to realize the movement of the entire transport vehicle. Figure 3 , Figure 4 and Figure 5 As shown, the track-changing control assembly 4 includes a box body 401 fixedly connected to the bottom of the suspension platform 1, a driving member 402 is fixedly arranged in the middle of the box body 401, a driving wheel 403 is arranged at the output end of the driving member 402, and driven wheels 404 are respectively connected to the two lifting platforms 301 on both sides of the driving wheel 403, and the driving wheel 403 and the two driven wheels 404 are linearly arranged and distributed in a transmission matching manner, and the diameters of the three are the same. The driving member 402 is used to drive the driving wheel 403 to rotate. The driving member 402 can be a motor, and of course, it can also be pneumatic to drive the driving wheel 403 to rotate. It is mentioned above that a travel assembly 3 is used to achieve The transport vehicle moves, because the driving wheel 403 and the driven wheel 404 are the same, which makes different changes in the rotation angle of the driving wheel 403. If the driving wheel 403 rotates 180°, the suspension platform 1 and the other travel component 3 will change direction. This rotation process is to switch the driving guide rail. It should be noted that the driving wheel 403 and the driven wheel 404 can be driven in the form of gear meshing, and of course, friction transmission can also be used. When the transport vehicle transports heavier items, one travel component 3 may not be able to bear it, so the driving wheel 403 can be rotated 90°, and then the lifting platform 301 is raised. At this time, it will appear as follows Figure 3 In the state shown, the two traveling components 3 are distributed linearly, which means that the two traveling components 3 can be located in the same driving guide rail, so that the transport vehicle has a more stable structure. It is precisely because the suspension platform 1 can rotate that the transport vehicle has many working forms and can adapt to the needs of various working conditions.

[0038] like Figure 1 , Figure 2 and Figure 6 As shown, as a preferred embodiment of the present invention, the lifting platform 301 includes a turntable 3011 rotatably connected to the suspension platform 1, a first platform 3012 is fixedly connected to the top of the turntable 3011, a second platform 3013 is spaced apart on the top of the first platform 3012, the first platform 3012 and the second platform 3013 are connected by vertically arranged first telescopic members 3014 on both sides, the power unit box 302 and the driving wheel 303 are arranged on the second platform 3013, and the sliding assembly 304 is located between the first platform 3012 and the second platform 3013.

[0039] In one case of the present embodiment, the first telescopic member 3014 can be an electric telescopic rod, and of course, it can also be a pneumatic telescopic form. A plurality of directional slide grooves 6 are provided on the second platen 3013, and the directional slide grooves 6 are vertically arranged relative to the length direction of the second platen 3013. The sliding assembly 304 includes a sliding base 3041 located in the directional slide groove 6, and the power unit box 302 is fixedly connected to the top of the sliding base 3041, and a slider 3042 is fixedly connected to the bottom of the sliding base 3041. The sliding assembly 304 also includes a guide block 3043 fixedly connected to the first platen 3012, and the slider 3042 and the guide block 3043 are slidably connected, and the contact surface between the slider 3042 and the guide block 3043 is an inclined surface, and the output end is not facing the direction. The inclined surfaces of the guide blocks 3043 corresponding to the same power unit boxes 302 are in a relative state. Generally speaking, the lifting and lateral movement of the power unit box 302 require two power sources to be realized. In the present embodiment, during the rising process of the second platform 3013, due to the cooperation restriction of the guide block 3043 and the slider 3042, the sliding base 3041 needs to move laterally, so that the driving wheel 303 can move to both sides. The driving wheel 303 can be opened when it rises and can be retracted when it descends, making the entire structure more efficient. It should be noted that the lifting height of the slider 3042 on the guide block 3043 requires that the driving wheels 303 in the two states have a certain height difference to ensure that the driving wheels 303 can smoothly detach from the travel guide rails.

[0040] like Figure 2 As shown, as a preferred embodiment of the present invention, the suspension component 5 includes a slide bar group 501 fixedly connected to both sides of the bottom of the box body 401, the slide bar group 501 is composed of two slide bars arranged at intervals, the slide bar itself is arranged horizontally, and the slide bar is perpendicular to the lifting platform 301 in the initial state, the suspension component 5 includes a suspension seat 502 whose two ends are respectively slidably connected to the slide bar groups 501 on both sides, the suspension seat 502 is fixedly connected to the storage box 2, and a horizontally arranged second telescopic member 503 is fixedly connected between the suspension seat 502 and the box body 401, and the second telescopic member 503 is used to drive the suspension seat 502 to move horizontally on the slide bar groups 501 on both sides.

[0041] In one case of the present embodiment, the second telescopic member 503 can be an electric telescopic rod, and of course, it can also be a pneumatic telescopic form. When a traveling component 3 is used for transportation, since it is on one side of the suspension platform 1, the overall structure will be unbalanced. The second telescopic member 503 can change the lateral position of the storage box 2 below, so that the transport vehicle can adjust the overall weight distribution according to the actual situation during transportation, so that it can be transported more smoothly.

[0042] like Figure 7 and Figure 8 As shown, as a preferred embodiment of the present invention, the transport storage box 2 includes a hanger 201 connected to the suspension assembly 5, and a laterally arranged receiving plate 202 is fixedly connected to the bottom of the hanger 201, and enclosures 203 are fixedly connected on both sides of the receiving plate 202. The enclosures 203 are relatively arranged with respect to the receiving plate 202, and baffles 204 are rotatably arranged on the other two sides of the receiving plate 202. A switch assembly 205 for rotating the baffle 204 is also arranged on the receiving plate 202.

[0043] In one case of this embodiment, the switch assembly 205 includes a support leg box body 2051 fixedly connected to both sides of the receiving plate 202, the baffle 204 is rotatably arranged between the support leg box body 2051, a control gear 2052 connected to the baffle 204 is arranged in the support leg box body 2051, a rack 2053 meshing with the control gear 2052 is arranged in the bottom of the support leg box body 2051 for horizontal sliding, and a top column 2054 is arranged on the side of the support leg box body 2051 away from the receiving plate 202 for horizontal sliding, and the top column 2054 is located in the support leg box body One end of the body 2051 is fixedly connected to the rack 2053, and the other end of the top column 2054 on both sides is fixedly connected through the cross frame 2055 located on one side of the receiving plate 202. The top column 2054 is provided with an elastic reset member 2056. When the elastic reset member 2056 is in the initial state, the baffle 204 and the receiving plate 202 are perpendicular to each other. The moving stroke of the rack 2053 is greater than 1 / 4 of the circumference of the indexing circle of the control gear 2052. The elastic reset member 2056 can be a spring, and of course, it can also be an air cushion. As long as The baffle 204 can be reset without external force. Generally speaking, the current logistics sorting and loading and unloading of items are achieved by manipulators. Because of the existence of the enclosure 203 and the baffle 204, the movement of the items and the manipulator is greatly limited. After adopting the above structure, when the transport vehicle moves to the specified position, a device can be set outside to contact the cross frame 2055. The cross frame 2055 will drive the rack 2053 to move through the top column 2054, and the control gear 2052 can drive the baffle 204 to rotate and open, which can effectively solve the problem of the baffle. The baffle 204 blocks the receiving plate 202, so that the items can be placed on the receiving plate 202 more conveniently. After the transport vehicle leaves, the cross frame 2055 loses its resistance effect, which will reset the baffle 204. During the movement of the transport vehicle, the baffle 204 can also provide a certain blocking effect. The two baffles 204 are distributed relative to the receiving plate 202 along the moving direction of the traveling component 3, which can mainly make loading and unloading more convenient. The baffle 204 on one side can be opened to load items, while the baffle 204 on the other side can be opened to unload items.

[0044] The embodiment of the present invention further provides a rail-changeable logistics suspension rail transportation method, the rail-changeable logistics suspension rail transportation method comprising the following steps:

[0045] Step 1: Select the travel component 3 to be used, control the power unit box 302 to rise through the lifting platform 301, and at the same time, move the driving wheels 303 to both sides to open, so that the driving wheels 303 cooperate with the driving guide rails to realize the movement of the transport vehicle;

[0046] Step 2: The horizontal frame 2055 is used to contact with an external object to realize the lateral movement of the rack 2053, and the rack 2053 drives the control gear 2052 to rotate, so that the baffle 204 rotates and opens, and the goods are placed on the receiving plate 202. When the transport vehicle moves, the elastic reset member 2056 resets the baffle 204, and the baffle 204 and the enclosure 203 cooperate to limit the position of the goods.

[0047] Step 3: When the transport vehicle changes tracks, the driving wheel 403 is driven to rotate by the driving member 402. Since the traveling component 3 on one side is restricted by the traveling guide rail and cannot rotate, the overall structure of the suspension platform 1 will rotate, so that the other traveling component 3 is turned to the other side, so that the traveling component 3 corresponds to the position of the other traveling guide rail, and the cooperation with the traveling guide rail is achieved through the lifting platform 301 of the traveling component 3. The traveling component 3 that originally drives the transport vehicle to move is lowered and retracted under the action of the lifting platform 301, and the traveling component 3 can be separated from the previous traveling guide rail.

[0048] In one case of the present embodiment, the evenly distributed characteristics of the traveling guide rails in logistics are utilized to drive the driving wheel to rotate through the driving member. Since the traveling component on one side is restricted by the traveling guide rail and cannot rotate, the overall structure of the suspension platform will rotate. The rotation of the suspension platform is utilized to adjust the position of the traveling component. The lifting of the lifting platform is also utilized to achieve the coordination or disengagement of the driving wheel and the traveling guide rail. In summary, the present transport vehicle can achieve rapid switching between different traveling guide rails, and even continuous switching.
