[0002] At present, the chassis of medium and heavy-duty AGV (Automated Guided Vehicle) is usually designed to be lower, so as to reduce the center of gravity and height of the medium and heavy-duty AGV, making the medium and heavy-duty AGV more stable and better adapted to different environments. When using a medium and heavy-duty AGV to carry heavy objects, once the medium and heavy-duty AGV fails and cannot move, it needs to be moved out of the route as soon as possible to avoid affecting the operation of other mobile equipment. However, due to the low chassis of the medium and heavy-duty AGV, it is difficult for forklifts and jacks to reach the bottom of the medium and heavy-duty AGV, resulting in the inability to carry the AGV or the carrying operation is very cumbersome.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1 and Figure 2A transport vehicle provided by an embodiment of the utility model includes a transport mechanism. The transport mechanism includes a fork structure 10 and a supporting member 20. The fork structure 10 includes a fork 11. The supporting member 20 is provided with a bearing surface 201a for bearing a first preset object. The supporting member 20 is detachably connected to the fork structure 10. When the supporting member 20 is connected to the fork structure 10, the height of the upper surface 11a of the fork 11 is greater than the height of the bearing surface 201a.

[0031] Exemplarily, the first preset object may be an autonomous moving device, such as an AGV.

[0032] It can be understood that the fork structure 10 can be raised and lowered in the height direction. When the first preset object needs to be transported, if the chassis of the first preset object is low, even if the fork structure 10 is lowered to the lowest position, the height of the upper surface 11a of the fork structure 10 is still greater than the height of the chassis of the first preset object. By providing the supporting member 20 and making the supporting member 20, when connected to the fork structure 10, the height of the upper surface 11a of the fork 11 is greater than the height of the bearing surface 201a. The height of the bearing surface 201a of the supporting member 20 can be adapted to the height of the chassis of the first preset object, so that the supporting member 20 can be connected to the fork 11 when at least part of it is placed in the gap at the bottom of the first preset component, and then the supporting member 20 can be driven to rise by the fork structure 10, so that the supporting member 20 can lift the first preset object and transport it to the predetermined position.

[0033] Taking the first preset object as an AGV as an example, when the AGV fails while moving on the ground to transport objects, the supporting member 20 can be separated from the fork structure 10, and then the supporting member 20 can be placed in the gap between the chassis of the AGV and the ground, and the supporting member 20 can be located between the front and rear rows of wheels of the AGV. At this time, the bearing surface 201a of the supporting member 20 can be in contact with the chassis of the AGV or lower than the chassis of the AGV, and then the fork structure 10 can be lowered to the lowest position and connected to the supporting member 20. Finally, the supporting member 20 is driven up by the fork structure 10, and the supporting member 20 lifts the AGV to move the AGV away, thereby preventing the failed AGV from affecting the operation of other mobile equipment.

[0034] It is worth noting that the height difference of the portion of the supporting member 20 placed at the bottom gap of the first preset object in the height direction needs to be adapted to the height of the bottom gap of the first preset object so that the portion can be placed at the bottom gap of the first preset object.

[0035] In some embodiments, the fork structure 10 includes a connecting member 12 and at least two forks 11, each fork 11 is connected to the connecting member 12, each fork 11 is arranged at intervals along a first direction perpendicular to the height direction, and the two ends of the supporting member 20 along the first direction are respectively detachably connected to the two forks 11. It can be understood that the bearing surface 201a of the supporting member 20 is located between the two forks 11, and the two ends of the supporting member 20 along the first direction are respectively connected to the two forks 11, so that when the supporting member 20 lifts the first preset object, both ends of the supporting member 20 are subjected to the force of the forks 11, which is conducive to ensuring the structural stability of the supporting member 20 and the stability of supporting the first preset object.

[0036] For example, the height direction is Figure 1 As shown in the Z direction, the first direction is Figure 1 As shown in the Y direction.

[0037] Further, each fork 11 includes a main body 111 and a bending member 121. The main body 111 of each fork 11 is arranged at intervals along the first direction and connected to the connecting member 12. The bending member 121 includes a first bending portion 1121 and a second bending portion 1122 connected to the first bending portion 1121. The first bending portion 1121 is connected to a side of the main body 111 facing the other main body 111, and the second bending portion 1122 extends from the side of the first bending portion 1121 facing the ground to the other main body 111. The two ends of the supporting member 20 along the first direction are detachably connected to the two second bending portions 1122. It can be understood that the second bending portion 1122 is connected to the side of the first bending portion 1121 facing the ground, so that the second bending portion 1122 is closer to the ground, so as to facilitate the connection between the second bending portion 1122 and the supporting member 20, and the second bending portion 1122 extends toward the other main body 111, so as to increase the area of ​​the second bending portion 1122 that can be used for connection with the supporting member 20, thereby ensuring the connection stability between the supporting member 20 and the fork 11.

[0038] In some embodiments, both sides of the supporting member 20 along the first direction are provided with a receiving groove 20a, and the receiving groove 20a is used to receive the second bent portion 1122, so that the supporting member 20 is supported on the fork 11. It can be understood that the second bent portion 1122 extends to be located in the receiving groove 20a and can be in contact with the groove wall surface of the receiving groove 20a, so that the fork 11 can lift the supporting member 20 and drive the supporting member 20 to rise, and also increase the connection area between the supporting member 20 and the second bent portion 1122, which is conducive to ensuring the connection stability between the supporting member 20 and the fork 11.

[0039] Exemplarily, each fork 11 extends along the second direction, and the accommodating groove 20a passes through the opposite sides of the supporting member 20 along the second direction, so that when the supporting member 20 is placed in the gap at the bottom of the first preset object, the fork 11 can move along the second direction, and the second bent portion 1122 of the fork 11 moves from one side of the supporting member 20 along the second direction to be accommodated in the accommodating groove 20a. The second direction is perpendicular to the height direction and the first direction, such as Figure 1 The X direction is shown in FIG.

[0040] Further, the supporting member 20 includes a first portion 21, a second portion 22, and a third portion sequentially arranged along the first direction, the second portion 22 is sunken toward the ground along the height direction to form a sunken portion, so that the first portion 21 and the second portion 22 form a receiving groove 20a, the second portion 22 and the third portion form another receiving groove 20a, and the sunken portion is provided with a bearing surface 201a. By sunken the second portion 22 to form a sunken portion, the second portion 22 can form a receiving groove 20a with the first portion 21 and the second portion 22 respectively, which is also conducive to controlling the weight of the supporting member 20.

[0041] Exemplarily, the recessed portion may include a bottom portion and side portions connected to both sides of the bottom portion in the first direction. The bottom portion is a flat structure to facilitate setting the bearing surface 201a. One of the side portions is connected to the first portion 21 and extends from the first portion 21 to the ground to connect to one side of the bottom portion, and the other side portion is connected to the second portion 22 and extends from the second portion 22 to the ground to connect to the other side of the bottom portion.

[0042] Furthermore, a first reinforcement member 201 is provided on the side of the recessed portion facing away from the ground, and a bearing surface 201a is provided on the side of the first reinforcement member 201 facing away from the recessed portion. The first reinforcement member 201 extends along the first direction. This is beneficial to enhancing the strength of the supporting member 20 and ensuring that the supporting member 20 can stably carry the first preset object without being easily deformed.

[0043] Exemplarily, a plurality of first reinforcement members 201 may be disposed on the recessed portion at intervals along the second direction.

[0044] In some embodiments, the supporting member 20 is provided with first positioning holes 20b penetrating opposite sides thereof in the height direction, the second bending portion 1122 of the fork 11 is provided with a second positioning hole, and the transport mechanism further comprises a positioning member, which is passed through the first positioning hole 20b and the second hole, so as to define the relative relationship between the supporting member 20 and the second bending portion 1122, ensure the connection stability between the supporting member 20 and the second bending portion 1122, and ensure the stability of supporting the first preset object.

[0045] Exemplarily, the positioning member may be a positioning pin.

[0046] In some embodiments, the supporting member 20 is provided with a first clamping portion, and the second bending portion 1122 is provided with a second clamping portion, and the first clamping portion is used to clamp with the second clamping portion. Exemplarily, one of the first clamping portion and the second clamping portion is a groove, and the other is a convex block. Through the clamping of the first clamping portion and the second clamping portion, the relative relationship between the supporting member 20 and the second bending portion 1122 is defined, and the connection stability between the supporting member 20 and the second bending portion 1122 and the stability of supporting the first preset object are ensured.

[0047] like Figure 3 As shown, in some embodiments, the fork structure 10 includes a connecting member 12 and at least two forks 11. Each fork 11 is connected to the connecting member 12. Each fork 11 is arranged at intervals along a first direction perpendicular to the height direction, and the supporting member 20 is detachably connected to the fork 11. The transport mechanism also includes at least two brackets 30, and the two brackets 30 are respectively arranged on the upper surfaces 11a of the two forks 11, and the brackets 30 are used to carry the second preset object. It can be understood that when the first preset object is loaded with the second preset object, when the supporting member 20 is separated from the fork structure 10, the second preset object can be stably lifted from both sides of the first preset object by the brackets 30 arranged on the upper surfaces 11a of the two forks 11, and after the second preset object is moved away from the first preset object, the second preset object is transported together by the supporting member 20 and the fork structure 10.

[0048] Specifically, the second preset object may be the same as or different from the first preset object. Exemplarily, the second preset object includes goods.

[0049] Furthermore, the bracket 30 includes a first frame 31 and a second frame 32, wherein the first frame 31 is disposed on the upper surface 11a of the fork 11, and the second frame 32 is connected to an end of the first frame 31 away from the fork 11 and extends in the first direction. By extending the second frame 32 in the first direction and using the second frame 32 to hold up the second preset object, it is beneficial to increase the connection area between the bracket 30 and the second preset object, so as to stably hold up and carry the second preset object.

[0050] Exemplarily, the first frame 31 and the second frame 32 may include a plurality of rods spaced apart along the second direction, and the plurality of rods are connected by a rod extending along the second direction.

[0051] Furthermore, the bracket 30 further includes a second reinforcement member connected between the first frame body 31 and the second frame body 32. By providing the second reinforcement member between the first frame body 31 and the second frame body 32, it is beneficial to enhance the stability of the bracket 30 and ensure that the bracket 30 can stably hold the goods.

[0052] like Figure 4As shown, in some embodiments, the supporting member 20 includes a connecting portion 23 and a supporting portion 24, the connecting portion 23 is detachably connected to the fork 11, the supporting portion 24 is connected to the side of the connecting portion 23 facing the ground in the height direction and is bent relative to the connecting portion 23, and the side of the supporting portion 24 facing away from the ground in the height direction is provided with a bearing surface 201a. When the first preset object is transported by the transport mechanism, the supporting member 20 and the fork 11 can be separated, the supporting portion 24 of the supporting member 20 is placed in the gap at the bottom of the first preset object, and then the connecting portion 23 of the supporting member 20 is connected to the fork 11, so that the fork structure 10 can drive the supporting member 20 to rise, and the supporting member 20 lifts the first preset object to transport the first preset object to a predetermined position.

[0053] For example, the connection portion 23 may be connected to the fork 11 by snapping or by a fastener.

[0054] Furthermore, the transport mechanism includes two supporting members 20, and the supporting parts 24 of the two supporting members 20 can extend from the two sides of the first preset object along the first direction to the bottom gap of the first preset object, and the connecting parts 23 of the two supporting members 20 are respectively connected to the inner side of the corresponding fork 11, that is, connected to the side of the fork 11 facing the other fork 11, so that the fork structure 10 drives the two supporting members 20 to rise at the same time, and the two supporting members 20 hold up the first preset object together.

[0055] like Figure 1 and Figure 4 As shown, in some embodiments, the transport vehicle includes a hydraulic transmission mechanism, a handle and a roller. The bottom of the fork structure 10 may be provided with a roller, and the hydraulic transmission mechanism may be provided with a roller.
