Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of automatic guided transport, and particularly relates to a carrying device. BACKGROUND
[0002] In the related art, the carrying device comprises a vehicle body and a carrying arm arranged on the vehicle body. The carrying arm comprises an arm body and a lifting mechanism arranged on the arm body. The carrying arm can be extended out of the vehicle body to lift goods by the lifting mechanism, so that the goods are placed on the vehicle body and then transported to a destination by the vehicle body.
[0003] However, many pallets carrying goods are Euro pallets, which have a beam structure at the bottom, that is, the bottom of the pallet has a protruding structure. When the lifting mechanism lifts the pallet, the contact area between the first supporting surface of the lifting mechanism and the bottom surface of the pallet is small, which is prone to unstable lifting and the goods are prone to tipping over or even falling. Therefore, the carrying device can only stably carry ordinary pallets carrying goods, resulting in poor compatibility and low versatility of the carrying device. CONTENT OF THE UTILITY MODEL
[0004] The purpose of the embodiments of the application is to provide a carrying device which can solve the problems of poor carrying stability and poor compatibility of the carrying device in the related art.
[0005] The embodiments of the application provide a carrying device comprising a vehicle body and a carrying arm. The carrying arm is in sliding connection with the vehicle body. The carrying arm comprises a lifting mechanism and a lifting top plate. The lifting mechanism is connected with the lifting top plate to drive the lifting top plate to move in the height direction of the carrying arm,
[0006] The lifting top plate is provided with a first supporting surface, and the first supporting surface is provided with a slot. In the case that the first supporting surface carries a to-be-carried object, the protruding structure of the to-be-carried object extends into the slot.
[0007] In the embodiments of the application, the carrying arm carries the to-be-carried object through the lifting top plate, and the lifting top plate is provided with a slot. When the carrying arm carries the to-be-carried object, the protruding structure of the to-be-carried object can extend into the slot, so that the bottom surface of the to-be-carried object smoothly contacts the first supporting surface, avoiding the protruding structure from interfering with the contact between the first supporting surface and the to-be-carried object. This is conducive to increasing the contact area between the first supporting surface and the to-be-carried object, improving the stability of the first supporting surface in carrying the to-be-carried object, and further improving the stability of the to-be-carried object in the lifting process, effectively avoiding the problem of the to-be-carried object tipping over or even falling. Therefore, the carrying device in the embodiments of the application can not only stably carry ordinary pallets carrying goods, but also stably carry Euro pallets carrying goods. Therefore, the carrying device has stronger versatility and compatibility and a wider application range. BRIEF DESCRIPTION OF DRAWINGS

[0032] Please refer to Figures 1-9 The conveying device disclosed in this application includes a vehicle body 100 and a conveying arm 200. The conveying arm 200 is slidably connected to the vehicle body 100 and can slide relative to the vehicle body 100. Optionally, the vehicle body 100 is provided with a receiving groove 110, the extending direction of the receiving groove 110 is consistent with the extending direction of the conveying arm 200, and the conveying arm 200 can extend out of the receiving groove 110 or extend into the receiving groove 110.
[0033] In this embodiment, the handling arm 200 can be an automated guided vehicle (AGV), which can be used to handle various types of goods or shelves.
[0034] The carrying arm 200 comprises a lifting mechanism 220 and a lifting top plate 210, the lifting mechanism 220 is connected with the lifting top plate 210 to drive the lifting top plate 210 to move in the height direction of the carrying arm 200, and the lifting mechanism 220 can be a telescopic cylinder, a foldable structure or the like which can realize telescopic effect, and the upper end of the lifting mechanism 220 is connected with the lifting top plate 210 by welding, bonding or the like. Further optionally, in the extension direction of the carrying arm 200, the lifting mechanism 220 is located between the driving wheel 310 and the driven wheel 320.
[0035] Referring to Figure 2 and Figure 3 As shown in the figure, the lifting top plate 210 is provided with a first supporting surface 210a, which can be a plane. Moreover, the first supporting surface 210a is provided with a slot 211, and in the case that the first supporting surface 210a carries the to-be-carried object 500, the protruding structure of the to-be-carried object 500 extends into the slot 211. Optionally, the slot 211 can be a square slot, a circular slot or the like, and the shape of the slot 211 is not limited in the embodiment of the application. In summary, by opening the slot 211, a space is provided for the protruding structure of the to-be-carried object 500, so as to avoid the protruding structure from interfering with the contact between the first supporting surface 210a and the to-be-carried object 500.
[0036] In the embodiment of the application, the carrying arm 200 carries the to-be-carried object 500 through the lifting top plate 210, and the lifting top plate 210 is provided with the slot 211, so that when the carrying arm 200 carries the to-be-carried object 500, the protruding structure of the to-be-carried object 500 can extend into the slot 211, so that the bottom surface of the to-be-carried object 500 can smoothly contact the first supporting surface 210a, which is beneficial to increase the contact area between the first supporting surface 210a and the to-be-carried object 500, improve the stability of the first supporting surface 210a in carrying the to-be-carried object 500, and further improve the stability of the to-be-carried object 500 in the lifting process, thereby effectively avoiding the problem of overturning or even falling of the to-be-carried object 500.
[0037] When the carrying arm 200 carries the ordinary pallet carrying goods, the first supporting surface 210a of the lifting top plate 210 directly contacts the bottom surface of the ordinary pallet; when the carrying arm 200 carries the Euro pallet carrying goods, the crossbeam (i.e. the protruding structure) of the Euro pallet extends into the slot 211, so that the first supporting surface 210a stably contacts the bottom surface of the Euro pallet. Therefore, the carrying device in the embodiment of the application not only can stably carry the ordinary pallet carrying goods, but also can stably carry the Euro pallet carrying goods, so that the carrying device has stronger universality and compatibility and wider application range.
[0038] Optionally, the carrying arm 200 is rotatably provided with a driving wheel 310 and a driven wheel 320, the driving wheel 310 drives the carrying arm 200 to slide relative to the vehicle body 100. The driving wheel 310 and the driven wheel 320 are respectively arranged at two ends of the carrying arm 200 along the length direction of the carrying arm 200. Specifically, the carrying arm 200 is internally provided with a second driving mechanism, the second driving mechanism is connected with the driving wheel 310, so as to drive the driving wheel 310 to rotate and drive the carrying arm 200 to slide relative to the vehicle body 100.
[0039] In the optional embodiment, with reference to Figures 1-6 The carrying arm 200 further comprises a movable plate 240, the movable plate 240 is movably arranged at the slot 211, the movable plate 240 can be a square plate, a circular plate or the like, and the specific shape of the movable plate 240 is not limited in the embodiment of the application. The movable plate 240 is provided with a second supporting surface 240a, the second supporting surface 240a can be a plane, and the second supporting surface 240a is used for supporting the protruding structure of the to-be-carried object 500.
[0040] Specifically, when the movable plate 240 is not pressed, the second supporting surface 240a is flush with the first supporting surface 210a, that is, the first supporting surface 210a and the second supporting surface 240a are located in the same plane, at this time, the carrying arm 200 can smoothly extend into the bottom of the to-be-carried object 500, and the height of the second supporting surface 240a is greater than the height of the first supporting surface 210a, so as to avoid affecting the extension process of the carrying arm 200. When the movable plate 240 is pressed, that is, when the lifting top plate 210 carries the to-be-carried object 500, and the protruding structure of the to-be-carried object 500 extends into the slot 211, the movable plate 240 carries the protruding structure of the to-be-carried object 500, and the movable plate 240 moves relative to the lifting top plate 210, so that the height of the second supporting surface 240a is less than the height of the first supporting surface 210a, and the movable plate 240 extends into the slot 211.
[0041] Optionally, the movable plate 240 and the lifting top plate 210 can be slidably connected through matched sliding rails and sliding blocks, and the position of the movable plate 240 relative to the lifting top plate 210 is fixed by relying on the friction force between the sliding rails and the sliding blocks. When the movable plate 240 is pressed, the movable plate 240 slides relative to the lifting top plate 210.
[0042] In this embodiment, based on the first support surface 210a of the lifting top plate 210 supporting the object to be transported 500, the transport arm 200 is equipped with a movable plate 240. The second support surface 240a supports the protruding structure of the object to be transported 500, further increasing the contact area between the transport arm 200 and the object to be transported 500, which helps to further improve the stability of the object to be transported 500 during transport. Furthermore, the movable plate 240 can prevent debris on the object to be transported from falling into the slot 211 and entering the lifting mechanism 220, thus avoiding affecting the operation of the lifting mechanism 220.
[0043] Of course, in other embodiments, the transport arm 200 may not have the movable plate 240. The protruding structure of the transport arm 200 extends directly into the slot 211, and the object to be transported 500 is supported only by the first support surface 210a of the lifting top plate 210.
[0044] In one optional embodiment, one of the lifting top plate 210 and the movable plate 240 is provided with a guide post 212, and the other is provided with a guide hole, with the guide post 212 and the guide hole providing a guiding fit. Specifically, the guide post 212 can be provided on the lifting top plate 210, and the guide hole can be opened in the movable plate 240; alternatively, the guide post 212 can be provided on the movable plate 240, and the guide hole can be opened in the lifting top plate 210. In this way, the guide post 212 and the guide hole are used to achieve a sliding connection between the movable plate 240 and the lifting top plate 210, and to guide the movement direction of the movable plate 240 relative to the lifting top plate 210, ensuring the accuracy of the movement direction of the movable plate 240.
[0045] In another embodiment, reference Figure 6 As shown, one of the lifting top plate 210 and the movable plate 240 is provided with a plurality of guide posts 212 at intervals, and the other is provided with a plurality of guide holes at intervals. The guide posts 212 correspond one-to-one with the guide holes. Each guide post 212 extends into the corresponding guide hole and is guided and engaged with the corresponding guide hole. The direction of the guide post 212 and the guide hole is the direction of movement of the movable plate 240.
[0046] Optionally, the movable plate 240 is a square plate, and guide posts 212 are provided at the four corners of the movable plate 240. Four guide holes are provided at intervals at the bottom of the slot 211. The guide posts 212 can be square posts and the guide holes can be square holes; or, the guide posts 212 can be cylindrical and the guide holes can be round holes. The embodiments of this application do not limit the shape of the guide posts 212 and the guide holes, as long as the guide posts 212 and the guide holes are in a guiding fit.
[0047] By using the multiple sets of matched guide columns 212 and guide holes, the movement direction of the different positions of the movable plate 240 relative to the lifting top plate 210 is respectively guided, which is more conducive to the stable movement of the whole movable plate 240 relative to the lifting top plate 210, and further ensures the accuracy of the movement direction of the movable plate 240.
[0048] In an alternative embodiment, the carrying arm 200 further comprises a driving member, which is an electric driving member such as a linear module or a pneumatic driving member such as a pneumatic cylinder. When the to-be-carried object 500 is separated from the carrying arm 200, the pressure borne by the movable plate 240 disappears, and the driving member is used to push the movable plate 240 to reverse and reset, so that the first support surface 210a and the second support surface 240a are flush again.
[0049] In another embodiment, the carrying arm 200 further comprises an elastic member 213, which can be a spring, a compression spring or the like. The first end of the elastic member 213 is connected with the lifting top plate 210, and the second end of the elastic member 213 is connected with the movable plate 240. Alternatively, the first end of the elastic member 213 can be connected with the lifting top plate 210 by welding, bonding or the like, or the first end of the elastic member 213 directly abuts against the lifting top plate 210; the second end of the elastic member 213 can be connected with the movable plate 240 by welding, bonding or the like, or the second end of the elastic member 213 directly abuts against the movable plate 240.
[0050] When the movable plate 240 is pressed, the movable plate 240 moves relative to the lifting top plate 210, the elastic member 213 is elastically deformed, and the elastic member 213 accumulates elastic potential energy. When the to-be-carried object 500 is separated from the carrying arm 200, the protruding structure of the to-be-carried object 500 is separated from the movable plate 240, the pressure borne by the movable plate 240 disappears, the elastic force of the elastic member 213 is the main driving force, the elastic member 213 restores the elastic deformation and drives the movable plate 240 to reset, so that the first support surface 210a and the second support surface 240a are flush again.
[0051] By using the elastic force of the elastic member 213 to drive the movable plate 240 to reset, it is not necessary to rely on electric driving or pneumatic driving, which avoids the problem that the movable plate 240 cannot be normally reset due to power failure or gas failure, and is conducive to improving the stability of the movable plate 240 during the resetting process.
[0052] In an alternative embodiment, as shown in Figure 4 and Figure 5 , the carrying device further comprises an anti-slip sticker 241, which is attached to the second support surface 240a. Alternatively, the anti-slip sticker 241 can be attached to the second support surface 240a by bonding, and the anti-slip sticker 241 can be attached to part of the second support surface 240a or the whole second support surface 240a.
[0053] With the embodiment, the surface of the movable plate 240 is additionally provided with the anti-skid sticker 241, which prevents the protruding structure of the to-be-carried object 500 from sliding relative to the movable plate 240, ensures the position of the to-be-carried object 500 relative to the movable plate 240, and improves the stability of the to-be-carried object 500 during the carrying process.
[0054] Of course, in other embodiments, the carrying device can not be provided with the anti-skid sticker 241, and the second support surface 240a directly contacts the protruding structure of the to-be-carried object 500.
[0055] In an alternative embodiment, the number of the carrying arms 200 is one.
[0056] In another embodiment, as shown in FIG. 2B, the carrying arm 200 can slide relative to the vehicle body 100 along a first direction A, the number of the carrying arms 200 is at least two, the carrying arms 200 are arranged at intervals along a second direction B, and the slotted holes 211 of the respective lifting top plates 210 are arranged at intervals along the second direction B. The first direction A intersects the second direction B, and optionally, the first direction A is perpendicular to the second direction B. The first direction A and the second direction B are respectively perpendicular to the height direction of the carrying device. Figure 1 With the embodiment, the number of the carrying arms 200 is increased, the to-be-carried object 500 is simultaneously carried by the plurality of carrying arms 200, and the contact area between the carrying arms 200 and the to-be-carried object 500 is increased. Moreover, the slotted holes 211 of the respective lifting top plates 210 are sequentially opposite along the second direction B, so that the protruding structure of the same to-be-carried object 500 can simultaneously extend into the plurality of slotted holes 211, and the respective lifting top plates 210 avoid the protruding structure, thereby increasing the total contact area between the carrying arms 200 and the to-be-carried object 500, which is conducive to improving the stability of the to-be-carried object 500 during the carrying process.
[0057] In an alternative embodiment, one of the lifting top plate 210 and the vehicle body 100 is provided with a hanging groove 214, and the other is provided with a hook 400. The hook 400 can be hung into the hanging groove 214. When the hook 400 is hung into the hanging groove 214 and the lifting mechanism 220 is in the retracted state, the carrying arm 200 is in a suspended state.
[0058]
[0059] Optionally, the edge of the lifting top plate 210 is provided with a hook 400, and the groove wall surface of the accommodating groove 110 is provided with a hook groove 214; or the edge of the lifting top plate 210 is provided with a hook groove 214, and the groove wall surface of the accommodating groove 110 is provided with a hook 400. The shape of the hook 400 and the hook groove 214 is not limited in the embodiment, as long as the hook 400 can be hung into the hook groove 214 when the carrying arm 200 is in the retracted state and the lifting mechanism 220 is in the retracted state. The hook 400 can be connected to the lifting top plate 210 or the vehicle body 100 by welding, bonding, bolt connection or the like. The hook 400 can be a cylindrical structure or other shape, and the specific structure of the hook 400 is not limited in the embodiment.
[0060] Specifically, the carrying arm 200 is in the retracted state, and the hook 400 gradually hangs into the hook groove 214 during the retraction of the lifting mechanism 220. When the hook 400 and the hook groove 214 cooperate, the relative position of the vehicle body 100 and the lifting top plate 210 is fixed. At this time, the lifting mechanism 220 continues to retract, and the bottom of the carrying arm 200 is separated from the ground 600, so that the carrying arm 200 is in a suspended state.
[0061] By cooperating the hook 400 with the hook groove 214, the carrying arm 200 can be suspended, the driving wheel 310 is in a suspended state, and the movement of the vehicle body 100 is not affected by the contact between the driving wheel 310 and the ground 600. Moreover, the cooperation structure of the hook 400 and the hook groove 214 is simple, and the hook 400 can be directly hung into the hook groove 214 without other complex cooperation structures.
[0062] Of course, in other embodiments, the lifting top plate 210 and the vehicle body 100 can be provided with other structures instead of the hook 400 and the hook groove 214, which can realize the suspended setting of the carrying arm 200.
[0063] In further embodiments, the number of hook grooves 214 and hooks 400 is at least two, and each carrying arm 200 is provided with a hook 400 or a hook groove 214 on the opposite side in the second direction B, that is, each carrying arm 200 is suspended by two sets of cooperating hooks 400 and hook grooves 214. Such a setting is conducive to further improving the stability of the carrying arm 200 in the suspended state.
[0064] In optional embodiments, as shown in Figure 7 The outer part of the hook 400 is provided with a roller 410, and the hook 400 contacts the groove wall surface of the hook groove 214 through the roller 410. Optionally, the roller 410 can be a bearing, and the inner side of the bearing is connected to the hook 400.
[0065] In this embodiment, during the process of hook 400 being hung in hanging groove 214, hook 400 moves relative to the groove wall of hanging groove 214 via roller 410. The friction between hook 400 and hanging groove 214 is transformed from sliding friction to rolling friction, which helps to reduce friction and facilitates hook 400 being smoothly hung in hanging groove 214.
[0066] Of course, in other embodiments, the hook 400 may not have the roller 410, and the surface of the hook 400 may directly contact the groove wall of the hanging groove 214.
[0067] In this application, the vehicle body 100 is provided with a receiving groove 110, and the transport arm 200 can extend out of or into the receiving groove 110, as shown in the reference. Figures 2-4 As shown, the lifting arm 200 also includes a lifting base plate 230, which is connected to a lifting mechanism 220 located between the lifting base plate 230 and the lifting top plate 210. That is, the upper end of the lifting mechanism 220 is connected to the lifting top plate 210, and the lower end of the lifting mechanism 220 is connected to the lifting base plate 230. Through the extension and retraction of the lifting mechanism 220, the lifting base plate 230 and the lifting top plate 210 move closer and further apart. Optionally, both the drive wheel 310 and the traveling wheels are located on the lifting base plate 230.

Further optionally, the first rotating arm 221 and the second rotating arm 222 are slidably connected to the lifting base plate 230 via cooperating guide rails and guide blocks, and the first rotating arm 221 and the second rotating arm 222 are slidably connected to the lifting top plate 210 via cooperating guide rails and guide blocks.
[0069] The lifting bottom plate 230 is provided with a first sliding rail 231, and the vehicle body 100 is provided with a second sliding rail, the first sliding rail 231 and the second sliding rail respectively extend along the extension direction of the carrying arm 200, and the first sliding rail 231 and the second sliding rail are in sliding fit.

[0071] Optionally, the second sliding rail is provided with a sliding groove, the first sliding rail 231 extends into the sliding groove, and in the height direction of the carrying arm 200, the height of the sliding groove is greater than the height of the first sliding rail 231, so that the first sliding rail 231 can move in the height direction relative to the sliding groove. When the hook 400 is hung into the hanging groove 214 and the lifting mechanism 220 is in the retracted state, the first sliding rail 231 will not be separated from the sliding groove, and the sliding fit between the first sliding rail 231 and the second sliding rail is maintained.
