[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0045] This application provides a pallet 4 lifting device, such as Figure 1 As shown, the pallet 4 lifting device includes a base plate 1, a lifting mechanism 2, a drive mechanism 3, and a pallet 4. Both the lifting mechanism 2 and the drive mechanism 3 are mounted on the base plate 1. The pallet 4 is located on top of the lifting mechanism 2 and is detachable from it, with the top portion being the part furthest from the base plate 1. At least a portion of the lifting mechanism 2 can be driven by the drive mechanism 3, thereby causing the pallet 4 to move along a lifting direction or a first direction, the first direction being oblique to the lifting direction.

[0046] The tray 4 is usually used to place goods during the process of logistics transportation. The jacking mechanism 2 is used to jack up the tray 4, so as to increase the distance between the tray 4 and the base plate 1, so that the forks of a forklift or a fork rail device can be inserted below the tray 4, so as to lift the tray 4 for transportation and transfer.

[0047] The driving mechanism 3 is used to drive the jacking mechanism 2 to move and provide power for the jacking mechanism 2 to jack up the tray 4. The driving mechanism 3 can be an automatic device, which can act in response to a control signal sent by a control device, so as to realize automatic driving, and thus the tray 4 jacking device can realize automatic jacking of the tray 4.

[0048] In summary, the tray 4 jacking device provided by the embodiment of the present application places the tray 4 on the top of the jacking mechanism 2, uses the jacking mechanism 2 to support the tray 4 and the goods, and simultaneously drives the jacking mechanism 2 by the driving mechanism 3, so as to drive the tray 4 and the goods to move along the lifting direction or the first direction. Since the first direction is oblique to the lifting direction, when the tray 4 moves along the first direction, there is also displacement in the lifting direction. Therefore, the scheme of the embodiment of the present application can realize automatic jacking of the tray 4 and the goods, and is beneficial to improving the logistics efficiency.

[0049] In some embodiments of the present application, as shown in Figure 2 , the driving mechanism 3 includes a limiting frame 31, and the jacking mechanism 2 includes a jacking assembly 21, which is movably connected with the limiting frame 31 and can move along the lifting direction relative to the limiting frame 31.

[0050] The jacking assembly 21 can be driven to move by the limiting frame 31 in the driving mechanism 3, or can be driven to move by other components in the driving mechanism 3. When the jacking assembly 21 is driven to move, the limiting frame 31 and the jacking assembly 21 move relative to each other. The limiting frame 31 plays a role of guiding and limiting the movement of the jacking assembly 21, and limits the jacking assembly 21 to move along the lifting direction relative to the limiting frame 31. In this case, the movement direction of the jacking assembly 21 relative to the base plate 1 can be along the lifting direction, or can be along the first direction.

[0051] In some embodiments, as shown in Figure 1 and Figure 6 , the limiting frame 31 includes two limiting side plates 311, and the two limiting side plates 311 have a mounting interval 312 therebetween, and the jacking mechanism 2 is located in the mounting interval 312. Alternatively, as shown in Figure 1 , the number of jacking mechanisms 2 can be multiple, and the multiple jacking mechanisms 2 are arranged in the mounting interval 312 along the length direction of the two limiting side plates 311. In this way, uniform jacking of the tray 4 at different positions can be realized, and the jacking efficiency can be improved.

[0052] In some embodiments, as shown inFigure 6 As shown, a first sliding part 313 is provided on the facing surfaces of the two limiting side plates 311; as Figure 7 As shown, the lifting assembly 21 has a second sliding part 214 on each side. The first sliding part 313 is one of a sliding groove and a slider, and the second sliding part 214 is the other of a sliding groove and a slider. The sliding groove extends along the lifting direction, and the slider is slidably disposed in the sliding groove.

[0053] Through the sliding engagement between the groove and the slider, the limiting frame 31 achieves the limiting and guiding function of the lifting assembly 21 in a simple structure. The groove extends along the lifting direction, and the slider is adapted to slide along the extension direction of the groove.

[0054] In some embodiments, the lifting mechanism 2 includes a guide block 22 having an inclined surface 221 that is inclined in a first direction; the lifting assembly 21 contacts the inclined surface 221 and is able to move on the inclined surface 221 in the first direction.

[0055] The top surface of the guide block 22 away from the base plate 1 is an inclined surface 221, which extends obliquely along a first direction. Therefore, when the lifting assembly 21 moves on the inclined surface 221, the lifting assembly 21 has displacement in the lifting direction, thus changing the distance between the tray 4 and the base plate 1. That is, in this embodiment, the lifting assembly 21, which moves along the first direction on the inclined surface 221, also moves relative to the base plate 1 in the first direction.

[0056] For example, the guide block 22 can be a structure such as a wedge block or a trapezoidal block, whose top surface is inclined relative to the base plate 1.

[0057] The lifting component 21 contacts the inclined surface 221 and moves along the extension direction of the inclined surface 221. The movement can be, for example, sliding or rolling. When sliding is used, the roughness of the inclined surface 221 is small, and the roughness of the contact surface of the lifting component 21 that contacts the inclined surface 221 is also small, so as to reduce the sliding friction between the two and thus reduce the driving difficulty of the drive mechanism 3.

[0058] Optionally, such as Figure 7 As shown, the lifting assembly 21 includes a roller 211 and two support plates 212. The roller 211 is cylindrical, and its side surface contacts and engages with the inclined surface 221 of the guide block 22, where the side surface refers to the cylindrical surface of the roller 211. Shaft portions 213 are respectively provided on the two end faces of the roller 211, and the shaft portions 213 are coaxial with the roller 211. A second sliding portion 214 is formed on the surface of each support plate 212 facing the adjacent limiting side plate 311, and the top of the support plate 212 is used to support the pallet 4.

[0059] Under the driving of the driving mechanism 3, the roller 211 can roll on the slope 221. The two support plates 212 are respectively sleeved on the two shaft portions 213 of the roller 211, and relative rotation is generated between the two support plates 212 and the roller 211 along with the rolling of the roller 211, that is, the two support plates 212 only perform translational motion and do not perform rotational motion, so as to ensure the stability of bearing of the tray 4.

[0060] Optionally, the support plate 212 can be provided with a through hole, and an axial length of the through hole is less than an axial length of the shaft portion 213 on the end surface of the roller 211, so that a part of the shaft portion 213 protrudes from the support plate 212 towards a plate surface side of the adjacent limiting side plate 311. At this time, the protruding part of the shaft portion 213 can be taken as the second sliding portion 214, and correspondingly, the first sliding portion 313 on the limiting side plate 311 is a sliding groove, and the shaft portion 213 is slidingly limited in the sliding groove.

[0061] Optionally, the support plate 212 is provided with a groove on a plate surface thereof facing the roller 211, and the shaft portion 213 on the end surface of the roller 211 is located in the groove, so as to realize assembly of the jacking assembly 21. The support plate 212 has the second sliding portion 214 on a plate surface thereof facing the adjacent limiting side plate 311, and the second sliding portion 214 is in sliding cooperation with the first sliding portion 313 on the limiting side plate 311.

[0062] In some embodiments, as shown in Figure 3 The guide block 22 is fixed to the bottom plate 1, and the limiting frame 31 is movable relative to the bottom plate 1. The driving mechanism 3 includes a first power assembly 32 connected with the limiting frame 31, so as to drive the limiting frame 31 to move along a second direction, thereby driving the jacking assembly 21 to move along a first direction on the slope 221, where the second direction is perpendicular to the lifting direction.

[0063] As shown in Figure 3 The jacking assembly 21 is connected with the limiting frame 31 and is driven to move through the limiting frame 31, where the power of the limiting frame 31 is provided by the first power assembly 32, and the moving direction of the limiting frame 31 is the second direction. It should be noted that, in the embodiments of the present application, the displacement amount of the tray 4 along the first direction is a vector, which can be equivalent to a vector sum of a first displacement amount along the lifting direction and a second displacement amount along the second direction. That is, there is a vector relationship among the first direction, the second direction and the lifting direction.

[0064] For Figure 2 and Figure 3The movement principle of the lifting assembly 21 of the tray 4 lifting device is shown as follows: when the tray 4 is not lifted, the lifting assembly 21 is located at a lower (or the lowest) position on the slope 221. When the tray 4 needs to be lifted, the first power assembly 32 pulls the limiting frame 31 to move in the second direction, and the limiting frame 31 moves the lifting assembly 21 along the first slope 221. At this time, since the guide block 22 and the bottom plate 1 are relatively fixed, the lifting assembly 21 also moves in the first direction relative to the bottom plate 1 and moves in the lifting direction relative to the limiting frame 31 until it moves to a higher (or the highest) position on the slope 221, thereby increasing the distance between the tray 4 and the bottom plate 1, facilitating the fork of the fork rail equipment or forklift to extend below the tray 4. It should be understood that the height direction in the embodiment of the application is the lifting direction.

[0065] In the above embodiment, the first power assembly 32 can be selected as a screw mechanism, for example. Figure 4 As shown, the screw mechanism includes a servo motor 321, a lead screw 322, a nut seat 323, a guide rail 324 and a connecting block 325. The servo motor 321 is fixed on the bottom plate 1, the output shaft of the servo motor 321 is connected with the lead screw 322, and the lead screw 322 extends in the second direction. The nut seat 323 is sleeved on the lead screw 322 and can reciprocate in the second direction when the lead screw 322 is rotated by the servo motor 321; the guide rail 324 is arranged in the second direction and is spaced from the lead screw 322; and the connecting block 325 is connected with the nut seat 323 and the limiting frame 31 and is slidingly connected with the guide rail 324.

[0066] The screw mechanism is used to convert the rotary motion of the servo motor 321 into the linear motion of the nut seat 323, thereby driving the limiting frame 31 to reciprocate linearly in the second direction. Specifically, Figure 4 As shown, when the servo motor 321 operates, the output shaft thereof rotates and drives the lead screw 322 to rotate synchronously. The nut seat 323 is matched with the outer thread of the lead screw 322 based on the inner thread thereof, so that the nut seat 323 moves linearly along the length direction of the lead screw 322 when the lead screw 322 rotates. One end of the connecting block 325 is connected with the nut seat 323, and the other end is slidingly matched with the guide rail 324, so that the connecting block 325 can be driven to move by the nut seat 323 and the sliding direction thereof is limited to the second direction by the guide rail 324. The limiting frame 31 is connected with the connecting block 325, so that the limiting frame 31 reciprocates synchronously with the connecting block 325 in the second direction.

[0067] The embodiment of the present application drives by adopting the screw rod mechanism, and drives the jacking assembly 21 to move along the inclined surface 221 of the guide block 22 by the limiting frame 31, which reduces the space arrangement requirement of the driving mechanism 3 and the jacking mechanism 2 in the lifting direction, avoids the structure arrangement being too dense and complex in the lifting direction, and improves the rationality of space use. Meanwhile, the limiting frame 31 is used to drive, limit and guide the movement of the jacking assembly 21, the inclined surface 221 of the guide block 22 is used to support and guide the movement of the jacking assembly 21, which ensures the stability and reliability of the movement of the jacking assembly 21, and ensures the reliable jacking of the tray 4.

[0068] Optionally, as shown in Figure 4 The bottom plate 1 can be provided with at least one bearing seat 11, and the screw rod 322 passes through the inner hole of the bearing seat 11, so that the bearing seat 11 plays a supporting and limiting role on the screw rod 322, prevents the swing amplitude of the screw rod 322 from being too large when the screw rod 322 rotates, ensures the stability of the movement of the nut seat 323, and further ensures the jacking stability of the jacking assembly 21. When the number of bearing seats 11 is multiple, the multiple bearing seats 11 are arranged in the second direction, so that the screw rod 322 passes through the inner holes of them in turn.

[0069] Of course, in other embodiments, the first power assembly 32 can also select other driving devices, such as telescopic motors, electric push rods, etc. The driving device is connected with the limiting frame 31, and drives the limiting frame 31 to move linearly in the second direction through the telescopic movement of itself in the second direction.

[0070] In some other embodiments of the present application, as shown in Figure 5 The guide block 22 is movable relative to the bottom plate 1, and the limiting frame 31 is fixed to the bottom plate 1; the driving mechanism 3 includes a second power assembly 33, the second power assembly 33 is connected with the guide block 22 and drives the guide block 22 to move in the second direction, so that the jacking assembly 21 moves on the inclined surface 221 in the first direction, wherein the second direction is perpendicular to the lifting direction.

[0071] As shown in Figure 5 The jacking assembly 21 is connected with the limiting frame 31 and is limited in position and movement direction by the limiting frame 31. The jacking assembly 21 is driven to move by the guide block 22, wherein the power of the guide block 22 is provided by the first power assembly, and the movement direction of the guide block 22 is the second direction. As mentioned above, in the embodiment of the present application, there is a vector relationship among the first direction, the second direction and the lifting direction.

[0072] For Figure 5The movement principle of the lifting assembly 21 of the shown tray 4 lifting device is as follows: when the tray 4 is not lifted, the lifting assembly 21 is located at a lower (or lowest) position on the inclined surface 221. When the tray 4 needs to be lifted, the second power assembly 33 pushes the guide block 22 to move in the second direction, and the guide block 22 drives the lifting assembly 21 to move along the first inclined surface 221 at the same time. At this time, since the guide block 22 and the limiting frame 31 are movably connected, and the guide block 22 and the bottom plate 1 are movably connected, the lifting assembly 21 moves in the lifting direction relative to the bottom plate 1 and the limiting frame 31 under the drive of the guide block 22, until it moves to a higher (or highest) position on the inclined surface 221, thereby increasing the distance between the tray 4 and the bottom plate 1, facilitating the fork of the fork rail equipment or forklift to extend into the tray 4 below.

[0073] In this case, the second power assembly 33 can be selected as a telescopic mechanism. As shown in the figure, Figure 5 the telescopic mechanism includes an outer sleeve 331 and a telescopic rod 332, at least a part of the telescopic rod 332 is located in the outer sleeve 331 and can be telescoped in the second direction relative to the outer sleeve 331; the guide block 22 is connected with the telescopic rod 332.

[0074] The telescoping direction of the telescopic rod 332 is parallel to the second direction, so as to drive the guide block 22 to make linear reciprocating motion in the second direction. Specifically, Figure 5 when the tray 4 is not lifted, the telescopic rod 332 is retracted in the outer sleeve 331, and when the tray 4 needs to be lifted, the telescopic rod 332 is extended relative to the outer sleeve 331, thereby pushing the guide block 22 to move away from the outer sleeve 331. At this time, the guide block 22 generates relative motion between the inclined surface 221 and the lifting assembly, which is manifested as the lifting assembly 21 moving along the first direction on the inclined surface 221. Since the limiting frame 31 limits the movement direction of the lifting assembly 21 to the lifting direction, the lifting assembly 21 is lifted relative to the limiting frame 31 while moving along the first direction on the inclined surface 221, so as to increase the distance between the tray 4 and the bottom plate 1.

[0075] The embodiment of the present application drives the telescopic mechanism, and drives the jacking assembly 21 to move along the inclined surface 221 of the guide block 22 based on the cooperation of the inclined surface 221 of the guide block 22 with the jacking assembly 21 and the movement limiting effect of the limiting frame 31, thereby achieving the movement driving of the jacking assembly 21 in the lifting direction. Meanwhile, the device used in this scheme has a simple structure and can be arranged in the second direction, thereby reducing the space arrangement requirement of the driving mechanism 3 and the jacking mechanism 2 in the lifting direction, avoiding the too dense and complex structure arrangement in the lifting direction, and improving the rationality of space use. Meanwhile, the inclined surface 221 of the guide block 22 is used to support, drive and guide the movement of the jacking assembly 21, and the lifting frame is used to limit and guide the movement of the jacking assembly 21, thereby ensuring the stability and reliability of the movement of the jacking assembly 21 and ensuring the reliable jacking of the pallet 4.

[0076] Optionally, as shown in Figure 5 The bottom plate 1 can be provided with at least one bearing seat 11, and the telescopic rod 332 is arranged to extend through the inner hole of the bearing seat 11, so that the bearing seat 11 plays a supporting and limiting role on the telescopic rod 332, thereby ensuring the stability of the telescopic movement of the telescopic rod 332 and the jacking stability of the jacking assembly 21. When the number of bearing seats 11 is multiple, the multiple bearing seats 11 are arranged in the second direction in a spaced manner, so that the telescopic rod 332 extends through the inner holes of the bearing seats 11 in sequence.

[0077] Of course, in other embodiments, the second power assembly 33 can also use other driving devices, such as a lead screw 322 mechanism, and the like. The nut seat 323 of the lead screw 322 mechanism is connected with the guide block 22, and the lead screw 322 mechanism drives the guide block 22 to move linearly in the second direction through the linear reciprocating movement of the lead screw 322 mechanism in the second direction.

[0078] In summary, the pallet 4 jacking device provided by the embodiment of the present application places the pallet 4 on the top of the multiple support plates 212, uses the jacking mechanism 2 to support the pallet 4 and the goods, and the jacking assembly 21 in the jacking mechanism 2 can be driven by the driving mechanism 3, thereby driving the pallet 4 to move in the lifting direction or the first direction, that is, achieving the jacking of the pallet 4. The pallet 4 jacking device provided by the embodiment of the present application has a simple structure, reliable performance, reasonable space arrangement, and can realize the automatic jacking of the pallet 4 and the goods, thereby improving the logistics efficiency.
