Description

Technical Field

[0001] The present application relates to the field of transportation equipment, and in particular to a transportation device and a carrier thereof. Background Art

[0002] When people use transport vehicles to transfer goods, they need to manually move the goods onto and off the transport vehicles, which is too labor-intensive and has low loading and unloading efficiency.

[0003] When the amount of goods is large, people will use forklifts to move the goods onto or off the truck, but forklifts are expensive and require a large space to move. They are not only inflexible but also consume a lot of energy. Therefore, in scenarios where forklifts are not suitable, people still choose trolleys to move goods manually.

[0048] Reference below Figure 1-Figure 6 A transport device 100 according to an embodiment of the present application is described.

[0049] According to the transport device 100 of the first embodiment of the present application, Figure 1-Figure 3 As shown, it includes: a transport vehicle 10 and a carrier 20.

[0050] The transport vehicle 10 is provided with a lifting guide surface 122, which gradually decreases from one end to the other end. That is, one end of the lifting guide surface 122 is its upper end 122u, and the other end of the lifting guide surface 122 is its lower end 122d, and the height of the lifting guide surface 122 gradually decreases from the upper end 122u to the lower end 122d.

[0051] The carrier 20 is provided with a sliding member 26, at least a portion of which is higher than the lower end 122d of the lifting guide surface 122, so that the carrier 20 can slide along the lifting guide surface 122 to the transport vehicle 10 along with the sliding member 26. In other words, the transport vehicle 10 and the carrier 20 can be separated and used independently, that is, the carrier 20 and the transport vehicle 10 have the following structure: Figure 2 In the separated state shown, the carrier 20 and the transport vehicle 10 also have Figure 1 The combined state shown.

[0052] The lifting guide surface 122 on the transport vehicle 10 is used to guide the carrier 20 to get on and off the vehicle. When the transport vehicle 10 and the carrier 20 are in a separated state, since at least a portion of the sliding member 26 is higher than the lower end 122d of the lifting guide surface 122, when the transport vehicle 10 drives toward the carrier 20, or when the carrier 20 moves toward the transport vehicle 10, the sliding member 26 can cooperate with the lifting guide surface 122, and then slide along the lifting guide surface 122 toward the transport vehicle 10, so that the transport vehicle 10 and the carrier 20 can be turned into a combined state.

[0053] It should be noted here that when the carrier 20 and the transport vehicle 10 are in a separated state, the height relationship of the parts on the carrier 20 and the transport vehicle 10 is a height comparison made when the lower end 20d of the carrier 20 and the lower end 10d of the transport vehicle 10 are at the same height.

[0054] In the transport device 100 of the present application, when the carrier 20 and the transport vehicle 10 are separated, the carrier 20 and the transport vehicle 10 can each perform their respective functions, for example, the transport vehicle 10 can transport goods, and the carrier 20 can load and store goods. When the carrier 20 and the transport vehicle 10 are combined, the transport vehicle 10 can carry the carrier 20 and transfer the goods on the carrier 20. Therefore, the transport device 100 is highly practical, and the utilization rate of the transport vehicle 10 and the carrier 20 is also high.

[0055] By setting the lifting guide surface 122 on the transport vehicle 10, the carrier 20 can be loaded and unloaded very conveniently and quickly, which greatly reduces the labor intensity of loading and unloading. In addition, the carrier 20 can be used alone to load goods. When the goods in the carrier 20 need to be transferred, the carrier 20 can be directly transferred, and the goods do not need to be replaced by the carrier 20, which reduces the labor intensity of replacing the carrier 20. For example, the carrier 20 includes a support frame 25, which is a shelf for displaying goods. When the goods are loaded on the shelf and transferred by the transport vehicle 10, the merchant can move the shelf directly to the store. After the shelf is arranged in the store, there is no need to change the shelf for the goods, which can reduce the damage rate of the goods during transportation.

[0056] Since the carrier 20 can be easily loaded and unloaded on the transport vehicle 10, there are two ways to load the goods onto the vehicle. The carrier 20 can be first slid onto the transport vehicle 10, and then the goods can be loaded onto the carrier 20 on the vehicle after it is in place, or the goods can be first loaded onto the carrier 20 on the ground, and then the carrier 20 can be slid onto the transport vehicle 10. Similarly, there are two ways to unload the goods from the vehicle. In this way, the use of the transport device 100 is also very flexible, and the most efficient method can be selected according to the needs.

[0057] In addition, the transport vehicle 10 is provided with a lifting guide surface 122, and the carrier 20 is provided with a matching sliding member 26. Compared with the method of loading goods by a forklift, the combination of the two does not require too much space for the transport vehicle 10. Moreover, the transport vehicle 10 and the carrier 20 do not need to be provided with an overly complicated structure for loading and unloading, and the space utilization rate of the transport vehicle 10 and the carrier 20 is high, which also reduces the cost.

[0058] In some embodiments, Figure 1 As shown, the transport vehicle 10 includes a vehicle body 11 and a track member 12 disposed on the vehicle body 11, and the track surface of the track member 12 includes the above-mentioned lifting guide surface 122. The structure of the vehicle body 11 is not limited, and can be a flat plate, a box, etc., or other vehicle body structures known in the prior art.

[0059] The carrier 20 is provided with a support frame 25 and a sliding member 26 provided on the support frame 25. The carrier 20 is supported by the support frame 25. The support frame 25 is selected to support an object according to the structure. For example, the support frame 25 can be a shelf to support goods, the support frame 25 can be a cage to support animals, or the support frame 25 can be other structures to support other objects. Figure 6 The seat shown, or the support frame 25 can also be a bed, etc., so that when someone sits on the seat or lies on the bed, the transport vehicle 10 can be used for transfer. To simplify the description, the following description is based on the example of the support frame 25 being used for loading goods.

[0060] In some embodiments, Figure 1 and Figure 2 As shown, a horizontal guide surface 121 is provided on the transport vehicle 10, and the upper end 122u of the lifting guide surface 122 is arranged toward the horizontal guide surface 121. When the carrier 20 and the transport vehicle 10 are in a separated state, the lower end 26d of the sliding member 26 is lower than the horizontal guide surface 121; when the carrier 20 and the transport vehicle 10 are in a combined state, the sliding member 26 is located on the horizontal guide surface 121. The arrangement of the horizontal guide surface 121 enables the sliding member 26 to slide onto the transport vehicle 10 along the lifting guide surface 122, and then to further translate a distance, so that the carrier 20 is in a relatively stable position, and the carrier 20 is not easy to slide off the transport vehicle 10 along the lifting guide surface 122 when the transport vehicle 10 is traveling.

[0061] like Figure 2As shown, in the separated state, both the carrier 20 and the transport vehicle 10 are located on the ground, and the ground is the reference plane. The height of the lower end 26d of the sliding member 26 is h1, and the height of the horizontal guiding surface 121 is h2, where h1 < h2, that is, the lower end 26d of the sliding member 26 is lower than the horizontal guiding surface 121. And the height of the lower end 122d of the lifting guiding surface 122 is h3, and at least part of the sliding member 26 is higher than h3. This is to ensure that when the transport vehicle 10 and the carrier 20 approach each other in the separated state, at least part of the sliding surface of the sliding member 26 can contact the lifting guiding surface 122, so that when the carrier 20 is pushed (or pulled) towards the transport vehicle 10, the sliding member 26 can slide upward along the lifting guiding surface 122 and thus slide onto the horizontal guiding surface 121.

[0062] Specifically, the guiding surface of the rail member 12 includes the above-mentioned horizontal guiding surface 121. That is, the sliding member 26 can travel along the rail member 12 and move from the lifting guiding surface 122 to the horizontal guiding surface 121.

[0063] Furthermore, the lower end 26d of the sliding member 26 is higher than the lower end 20d of the carrier 20. In this way, when the carrier 20 is located on the ground, the sliding member 26 can be separated from the ground, so that it is not affected by the sliding member 26 during use.

[0064] In the separated state, the lower end 26d of the sliding member 26 is higher than or flush with the lower end 122d of the lifting guiding surface 122. This can improve the reliability of the cooperation between the sliding member 26 and the lifting guiding surface 122 and avoid the possibility that the sliding member 26 cannot contact the lifting guiding surface 122 when the carrier 20 and the transport vehicle 10 approach each other.

[0065] Here, the sliding member 26 slides on the guiding surface of the rail member 12, and the type of the sliding member 26 is not limited. For example, the sliding member 26 can be a slider. When the sliding member 26 is a slider, the bottom surface of the slider is the sliding surface that cooperates with the guiding surface of the rail member 12, and the slider can be a rectangular block or a sector block, etc. Also, for example, the sliding member 26 can be a roller, etc., and realizes sliding through rolling. When the sliding member 26 is a rectangular slider and the bottom surface is the sliding surface, it is required that the lower end 26d of the sliding member 26 is higher than the lower end 122d of the lifting guiding surface 122, that is, h1 > h3. When the sliding member 26 is a sector slider and the bottom surface is an arc-shaped sliding surface, it is required that the upper end of the arc-shaped sliding surface is higher than the lower end 122d of the lifting guiding surface 122. When the sliding member 26 is a roller, it is required that the axis of the roller is higher than the lower end 122d of the lifting guiding surface 122. In this way, when the transport vehicle 10 and the carrier 20 approach each other, the sliding member 26 can cooperate with the lifting guiding surface 122, and there is no need to lift the carrier 20 again, saving the labor intensity of transferring the carrier 20 onto the transport vehicle 10.

[0066] In the separated state, the lower end 26d of the sliding member 26 is lower than the horizontal guide surface 121, and in the combined state, the sliding member 26 is located on the horizontal guide surface 121, so that the transport vehicle 10 lifts the carrier 20 and the lower end 20d of the carrier 20 is off the ground. In this way, when the transport vehicle 10 moves, it can carry the carrier 20 and move.

[0067] In some embodiments, Figure 2 and Figure 3 As shown, the carrier 20 includes a running wheel 27 disposed at the bottom, so that when the carrier 20 is used alone, it is also convenient to use the running wheel 27 to transfer objects, further improving the convenience of using the carrier 20. The running wheel 27 can be a roller, or a universal wheel, etc.

[0068] Optionally, the lower end of the sliding member 26 is higher than the lower end of the running wheel 27, which is helpful to reduce the resistance caused by the friction between the sliding member 26 and the ground when the carrier 20 is pushed on the ground.

[0069] In some embodiments, Figure 2 and Figure 3 As shown, the carrier 20 includes support legs 252, which are two groups and are arranged at intervals, and the sliding member 26 is located between the two groups of support legs 252. When the sliding member 26 is moved onto the transport vehicle 10, the two groups of support legs 252 straddle the two sides of the transport vehicle 10.

[0070] Specifically, the support body 251 and the support legs 252 disposed at the bottom of the support body 251 belong to the support frame 25 of the carrier 20. In the combined state, the support body 251 is located on the vehicle body 11, and the two sets of support legs 252 straddle the two sides of the vehicle body 11. This arrangement is to keep the carrier 20 stable on the transport vehicle 10 when the carrier 20 is combined with the transport vehicle 10, especially when the transport vehicle 10 is moving, the stability of the carrier 20 can reduce the chance of rollover and improve transportation safety.

[0071] The support legs 252 also raise the height of the support body 251 , which can reduce the chance of bending down when taking or placing goods on the support body 251 .

[0072] Of course, the present application solution is not limited to this. For example, the support legs 252 can be omitted on the support frame 25. After the carrier 20 is moved onto the transport vehicle 10, other methods are used to position the carrier 20, such as using binding ropes.

[0073] In some specific embodiments, the sliding member 26 includes a roller 261, and at least one roller 261 is provided on the carrier 20. The roller 261 is usually arranged along a direction perpendicular to the length direction of the track member 12, for example, the axis of the roller 261 is perpendicular to the length direction of the track member 12. After using the roller 261, a longer contact line can be obtained with the track member 12, further reducing the probability of the carrier 20 tipping over on the transport vehicle 10.

[0074] Specifically, there may be at least two rollers 261 , and all the rollers 261 are arranged in parallel, so that the rollers 261 have less resistance when rolling on the track member 12 , and the carrier 20 slides more easily.

[0075] Of course, the present application is not limited thereto. When the sliding member 26 includes a roller 261 , it may also include a roller or a slider, etc., and different types of sliding members 26 may be used in combination.

[0076] In some specific embodiments, Figure 5 As shown, the support frame 25 is a storage rack, and at least one material frame 29 can be set on the storage rack to facilitate loading of goods. The material frame 29 can be detachably set on the support frame 25, and multiple material frames 29 can be set to increase the loading capacity.

[0077] Optionally, the support body 251 is provided in one or more layers, and one or more layers of goods can be placed thereon. Figure 5 In the embodiment, the support body 251 provides four layers of space for placing four layers of material frames 29. The support body 251 itself is a frame structure, which has a simple structure, is easy to process, and has a low cost.

[0078] Specifically, support legs 252 are respectively provided on both sides of the bottom of the support body 251. There are two support legs 252 on each side, and a walking wheel 27 is connected to the bottom of each support leg 252 to improve the overall convenience and stability of the carrier 20.

[0079] Furthermore, a roller 261 is disposed at the bottom of the support body 251, and two or more rollers 261 may be disposed. Figure 5 In the embodiment, rollers 261 are respectively provided at two ends of the bottom of the support body 251 .

[0080] In some specific embodiments, Figure 3 As shown, there are two rail members 12 on the transport vehicle 10, and the two rail members 12 respectively form guide surfaces 123 on the sides away from each other, and the guide surfaces 123 are located outside the vehicle body 11. The two guide surfaces 123 gradually move away from each other in the direction toward the horizontal guide surface 121. In this way, when the transport vehicle 10 approaches the carrier 20, the end provided with the guide surface 123 can be inserted between the support legs 252 (or other structures such as guide pillars) on both sides of the carrier 20, and the guide surface 123 is used to guide the vehicle 10 to automatically return to the center, so that the position of the carrier 20 and the transport vehicle 10 can be automatically adjusted, further improving the convenience of getting on the vehicle.

[0081] In other specific embodiments, Figure 6 As shown, the support frame 25 is a seat, and the chair legs of the seat are support legs 252. The bottom of the support leg 252 can be provided with a walking wheel 27, or it can be Figure 6The figure shows that no running wheels 27 are provided. A sliding member 26 is provided below the seat plate of the chair, and the sliding member 26 may include at least two rollers 261 and the like.

[0082] In some embodiments, Figure 2 As shown, the transport vehicle 10 is provided with wheels 14, and the wheels 14 include at least one of a passive wheel 141 and an active wheel 142. When the wheels 14 of the transport vehicle 10 only include the passive wheel 141, the transport vehicle 10 has no self-driving force and needs to be driven by an external force. For example, the transport vehicle 10 can be a cart, such as Figure 2 As shown, a handrail 15 is provided on the transport vehicle 10 .

[0083] When the wheels 14 of the transport vehicle 10 include at least one active wheel 142, the transport vehicle 10 also includes a driving device 143 connected to the active wheel 142, that is, the transport vehicle 10 has self-driving force, and the transport vehicle 10 is driven by the driving device 143. Here, the driving device 143 can be a motor, or an engine, etc., which is not limited here.

[0084] In the present application, when the track surface of the track member 12 includes the horizontal guide surface 121 and the lifting guide surface 122, the horizontal guide surface 121 and the lifting guide surface 122 can be connected or disconnected. As long as it does not affect the upward movement of the sliding member 26 along the lifting guide surface 122, the sliding member 26 can be moved to the horizontal guide surface 121.

[0085] For example, in the width direction of the track member 12, the horizontal guide surfaces 121 and the lifting guide surfaces 122 are alternately arranged. Specifically, there are two horizontal guide surfaces 121 and one lifting guide surface 122, and the two horizontal guide surfaces 121 are located on both sides of the lifting guide surface 122. The sliding member 26 of the carrier 20 includes three rollers arranged along the width direction of the track member 12. When getting on the vehicle, the middle roller contacts the lifting guide surface 122, and the vehicle can be gradually moved upward along the lifting guide surface 122. After getting on the vehicle, the rollers on both sides contact the horizontal guide surfaces 121 on both sides, so that the carrier 20 can remain stable after being in place.

[0086] In some specific embodiments, there are two rail members 12 on the transport vehicle 10, and the rail surface of each rail member 12 includes a horizontal guide surface 121. The roller 261 of the carrier 20 falls on the horizontal guide surfaces 121 of the two rail members 12, and is placed stably, reducing the probability of tilting and overturning.

[0087] Specifically, Figure 4As shown, the horizontal guide surface 121 of each track member 12 includes a parallel section 1211 and an asymptotic section 1212. The parallel sections 1211 of the two track members 12 are arranged in parallel, and the asymptotic sections 1212 of the two track members 12 gradually approach each other in the direction toward the lifting guide surface 122. In this way, when the roller 261 just moves onto the asymptotic section 1212, since the two asymptotic sections 1212 are close to each other, even if the roller 261 is slightly offset, it does not affect the contact with the two asymptotic sections 1212. Then, when the roller 261 continues to move upward along the asymptotic section 1212, the position of the roller 261 can be gradually adjusted on the asymptotic section 1212, and then when it is adjusted to the right position and moves onto the parallel section 1211, the two ends of the roller 261 can just fall onto the two parallel sections 1211.

[0088] Furthermore, on each track member 12, the lifting guide surface 122 and the asymptotic section 1212 are connected at the edge of the vehicle body 11. In this way, the track member 12 is located at the edge of the vehicle body 11 at the high bending part, and the shape of the vehicle body 11 itself does not need to be too complicated. Moreover, the force is concentrated at the bending part, and the edge of the vehicle body 11 can be effectively supported.

[0089] Optionally, a positioning surface 1213 is formed on the horizontal guide surface 121. Figure 2 As shown, a concave surface is formed on the horizontal guide surface 121, and the concave surface constitutes a positioning surface 1213. When the carrier 20 and the transport vehicle 10 are in a combined state, the sliding member 26 is located at the concave surface, which is conducive to further stabilizing the carrier 20 and reducing the risk of the carrier 20 falling during transportation.

[0090] In some embodiments, the transport vehicle 10 further includes a first positioning member 13, and the carrier 20 further includes a second positioning member 28; in the combined state, the first positioning member 13 and the second positioning member 28 are combined to position the carrier 20. In this way, when the transport vehicle 10 is traveling, the position of the carrier 20 is relatively stable, reducing the risk of the carrier 20 falling off the vehicle.

[0091] Specifically, Figure 4 and Figure 1 As shown, the first positioning member 13 includes: a positioning platform 131, a positioning rod 132 and a positioning pin 133. The lower end 131d of the positioning platform 131 can be connected to the vehicle body 11, and the positioning rod 132 is connected to the positioning platform 131 and extends toward the lifting guide surface 122. The positioning pin 133 is vertically movably arranged on the positioning rod 132, and the lower end 133d of the positioning pin 133 can extend to the bottom of the positioning rod 132. In the combined state, the second positioning member 28 is located below the positioning rod 132 and is stuck between the positioning platform 131 and the positioning pin 133. With this arrangement, the vertical movement operation of the positioning pin 133 can be performed on the vehicle body 10, and the insertion and removal of the positioning pin 133 is very simple and the cost is low.

[0092] Furthermore, the sliding member 26 is in the shape of an elongated strip, and the sliding member 26 is extended in a direction perpendicular to the length direction of the track member 12. With such arrangement, the first positioning member 13 can lock the sliding member 26 which is most easily movable, thereby improving safety.

[0093] In this type of solution, the sliding member 26 is a roller 261 extending along the width direction of the track member 12 . The roller 261 is long enough to facilitate the first positioning member 13 to lock the roller 261 .

[0094] Furthermore, sliding members 26 are provided at both ends of the carrier 20, and the sliding members 26 at both ends are arranged in parallel and can both constitute second positioning members 28. In this way, the transport vehicle 10 can load and lock the carrier 20 from both sides of the carrier 20, further improving its convenience of use.

[0095] Of course, the present application is not limited thereto, for example, the first positioning member 13 may be configured to clamp the support frame 25 from the side, etc. For another example, the first positioning member 13 may be an automatic lock.

[0096] Combine the following Figure 1-Figure 6 The structure of the carrier 20 according to the embodiment of the present application is described.

[0097] According to the second embodiment of the present application, the carrier 20 comprises: a support frame 25 and a sliding member 26 disposed on the support frame 25, wherein the lower end 26d of the sliding member 26 is higher than the lower end 20d of the carrier 20. The carrier 20 is carried by the support frame 25, and the support frame 25 selects the carrying object according to the structure. For example, the support frame 25 can be a storage rack to carry goods, the support frame 25 can be a cage to carry animals, or the support frame 25 can be other structures to carry other objects. Even, the support frame 25 can also be Figure 6 The seat shown, or the support frame 25 can also be a bed, etc., so that when someone sits on the seat or lies on the bed, the transport vehicle 10 can be used for transfer. To simplify the description, the following description is based on the example of the support frame 25 being used for loading goods.

[0098] The carrier 20 can be used alone or combined with the transport vehicle 10 through the sliding member 26. The specific combination method can be referred to the embodiment of the transport device 100 described above, which will not be repeated here. Therefore, the carrier 20 can be easily moved onto the transport vehicle 10, and loading and unloading are very convenient and efficient. The carrier 20 can also be used independently, and the utilization rate is high.

[0099] In the present application, the type of the sliding member 26 is not limited. For example, the sliding member 26 can be a slider. When the sliding member 26 is a slider, the bottom surface of the slider is a sliding surface that matches the track surface of the track member 12. The slider can be a rectangular block or a fan-shaped block.

[0100] In some specific embodiments, the sliding member 26 includes a roller 261 , and at least one roller 261 is disposed on the carrier 20 .

[0101] Specifically, there may be at least two rollers 261 , and all the rollers 261 are arranged in parallel, so that the rollers 261 have less resistance when rolling on the track member 12 , and the carrier 20 slides more easily.

[0102] Of course, the present application is not limited thereto. When the sliding member 26 includes a roller 261 , it may also include a roller or a slider, etc., and different types of sliding members 26 may be used in combination.

[0103] Optionally, the sliding member 26 includes a roller 261, and the two ends of the bottom of the support body 251 are provided with rollers 261 arranged in parallel. In this way, the carrier 20 can be smoothly boarded and unboarded from both sides.

[0104] In some embodiments, Figure 2 and Figure 3 As shown, the support frame 25 includes a support body 251 and support legs 252 arranged at the bottom of the support body 251. The support legs 252 are divided into two groups and arranged at intervals, and the sliding member 26 is located between the two groups of support legs 252. Such an arrangement is to keep the carrier 20 stable on the transport vehicle 10 when the carrier 20 is combined with the transport vehicle 10, especially when the carrier 20 is stable during the movement of the transport vehicle 10, which can reduce the chance of rollover and improve transportation safety.

[0105] The support legs 252 also raise the height of the support body 251, which can reduce the chance of bending when taking and placing goods from the support body 251. Of course, the present application solution is not limited to this. For example, the support legs 252 can be omitted on the support frame 25, and the carrier 20 can be positioned by other means after being moved onto the transport vehicle 10, such as by using a binding rope.

[0106] In some embodiments, Figure 2 and Figure 3 As shown, the carrier 20 includes a running wheel 27 disposed at the bottom, so that when the carrier 20 is used alone, it is also convenient to use the running wheel 27 to transfer objects, further improving the convenience of using the carrier 20. The running wheel 27 can be a roller, or a universal wheel, etc.

[0107] Optionally, the sliding member 26 is higher than the running wheel 27, which is helpful to reduce the resistance caused by the friction between the sliding member 26 and the ground when the carrier 20 is pushed on the ground.

[0108] In some specific embodiments, the support frame 25 includes a support body 251 and support legs 252 disposed at the bottom of the support body 251. The support legs 252 are divided into two groups and are arranged at intervals. The sliding member 26 is located between the two groups of support legs 252. The carrier 20 also includes walking wheels 27 disposed at the bottom of the support legs 252. In this way, the carrier 20 is convenient to walk when used independently, and it is convenient to use the support legs 252 to clamp the vehicle body 11 when loaded on the transport vehicle 10, thereby improving the transportation stability.
