For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] like Figures 1 to 3 As shown, this embodiment provides a transport vehicle, which includes a frame assembly 1, a roller assembly 2, and a transmission assembly 3. The frame assembly 1 includes a frame 11 and a pallet 12. The pallet 12 is located on one side of the frame 11 and slides with the frame 11 along the length direction X. The roller assembly 2 is disposed on the other side of the frame 11 and can rotate the frame 11. The axis of rotation of the frame 11 is consistent with the width direction Y of the frame 11. The transmission assembly 3 is disposed on the frame 11 and includes an input shaft 31 and an actuator that is drively connected to the input shaft 31. The input shaft 31 is configured to be detachably drively connected to the driver 100. The rotation of the input shaft 31 causes the actuator to drive the pallet 12 to slide relative to the frame 11. When workers need to move goods horizontally on the pallet 12, they only need to push or pull the frame 11. This allows the roller assembly 2 to move the goods horizontally. When the goods need to be lifted vertically, since the axis of rotation of the frame 11 is consistent with the width direction Y of the frame 11, the frame 11 can be rotated around the roller assembly 2, thereby aligning the length direction X of the frame 11 with the vertical direction. At this time, the external driver 100 is connected to the input shaft 31 of the transmission assembly 3, enabling the driver 100 to drive the pallet 12 vertically via the actuator, thus lifting the goods. When the lifting function is not needed, the driver 100 can simply be removed. When the pallet 12 needs to be lifted, the driver 100 only needs to be temporarily installed, without permanently fixing the driver 100 to the frame 11. This avoids increasing the overall weight of the pallet 11 and reduces the workload of the workers.

[0037] Alternatively, the driver 100 can be a rotary power tool commonly used by workers, such as a hand drill or electric drill.

[0038] Optionally, the frame body 11 is provided with two sliding grooves 1121 spaced apart along the width direction Y, and the openings of the two sliding grooves 1121 are oppositely arranged; the trolley assembly 1 further comprises two guide wheels 13, which are respectively rotatably arranged at the two ends of the tray 12 along the width direction Y, and the two guide wheels 13 are respectively located in the two sliding grooves 1121. In this embodiment, the two guide wheels 13 roll in the two sliding grooves 1121, thereby converting the sliding friction between the tray 12 and the frame body 11 into the rolling friction of the guide wheels 13, which can effectively improve the wear between the tray 12 and the frame body 11, and also reduce the power required for the tray 12 to slide relative to the frame body 11. The two guide wheels 13 respectively extend into the sliding grooves 1121 from the openings of the two sliding grooves 1121, thereby limiting the movement of the tray 12 along the width direction Y of the frame body 11.

[0039] Optionally, the frame body 11 comprises a support frame 111 and two guide members 112, the two guide members 112 are arranged on one side of the support frame 111 along the width direction Y, and the two sliding grooves 1121 are arranged on the two guide members 112, respectively. The transmission assembly 3 and the roller assembly 2 are arranged on the other side of the support frame 111. In this embodiment, the support frame 111 comprises two longitudinal beams 1111 and a plurality of cross beams 1112, the two longitudinal beams 1111 are arranged spaced apart along the width direction Y, the plurality of cross beams 1112 are arranged between the two longitudinal beams 1111 and spaced apart along the length direction X, and the two ends of the cross beam 1112 are fixedly connected with the two longitudinal beams 1111, respectively. The two guide members 112 are fixedly arranged on the two longitudinal beams 1111, respectively.

[0040] Optionally, the actuator comprises a plurality of anti-skid protrusions 14, which are arranged on one side of the frame body 11 along the length direction X. In this embodiment, the anti-skid protrusions 14 are arranged in two rows and arranged on the two guide members 112, respectively, and each row of anti-skid protrusions 14 is arranged spaced apart along the length direction X of the frame body 11. When the goods are arranged on the tray 12, the end of the goods away from the tray 12 abuts against the two guide members 112, and when the goods abut against the anti-skid protrusions 14, the anti-skid protrusions 14 can prevent the goods from sliding out of the tray 12.

[0041] Optionally, the anti-skid protrusions 14 are made of rubber.

[0042] Optionally, since there is rolling friction between the guide member 112 and the guide wheel 13, the guide member 112 is a wear part, so the guide member 112 and the corresponding cross beam 1112 are detachably connected. Specifically, the connection is achieved by screwing or clamping.

[0043] Optionally, the actuator comprises a screw rod 32 and a base 33. The screw rod 32 is rotatably arranged on the frame 11, and the axis of the screw rod 32 is arranged along the length direction X. The base 33 is arranged with a threaded hole 331 matched with the screw rod 32 along the length direction X. The screw rod 32 is arranged in the threaded hole 331. The base 33 is fixedly connected with the tray 12. One end of the screw rod 32 is in transmission connection with the input shaft 31. In this embodiment, the driver 100 drives the input shaft 31 to rotate, and then drives the screw rod 32 to rotate synchronously with the input shaft 31. The screw rod 32 is arranged in the threaded hole 331, so that the screw rod 32 drives the base 33 to move along the axis of the screw rod 32. Since the base 33 is fixedly connected with the tray 12, the tray 12 moves along the length direction X of the frame 11. In other embodiments, the actuator can also be a gear and a rack. The rack is arranged on the frame 11 along the length direction X of the frame 11. The rack is fixedly connected with the tray 12. The gear is rotatably arranged on the frame 11 and is in meshing connection with the rack. The input shaft 31 is in transmission connection with the gear. The driver 100 drives the input shaft 31 to rotate, and then drives the gear to rotate. At this time, the rack slides along the length direction X relative to the frame 11, and simultaneously, the rack drives the tray 12 to slide synchronously.

[0044] Optionally, the actuator further comprises a first bearing seat 34, a second bearing seat 35, a first bearing 36 and a second bearing 37. The first bearing seat 34 and the second bearing seat 35 are arranged on the frame 11 along the length direction X. The first bearing 36 and the second bearing 37 are arranged on the first bearing seat 34 and the second bearing seat 35, respectively. The two ends of the screw rod 32 are arranged in the first bearing 36 and the second bearing 37, respectively. The base 33 is located between the first bearing seat 34 and the second bearing seat 35. In this embodiment, the first bearing seat 34 and the second bearing seat 35 serve to fix the outer rings of the first bearing 36 and the second bearing 37, so that the first bearing 36 and the second bearing 37 are coaxially arranged. The screw rod 32 is arranged in the inner rings of the first bearing 36 and the second bearing 37 and is fixedly connected with the inner rings of the first bearing 36 and the second bearing 37, respectively. This arrangement can significantly reduce the force required for the input shaft 31 to drive the screw rod 32 to rotate.

[0045] Optionally, the transmission assembly 3 further comprises a strap 38. The strap 38 is used to fix the driver 100 on the frame 11. In this embodiment, when the driver 100 drives the input shaft 31 to rotate, the driver 100 itself will be subjected to a reaction force. At this time, the worker not only needs to hold the driver 100, but also needs to hold the goods on the tray 12. When there is only one worker, it is impossible to do both at the same time. Therefore, the strap 38 can be used to temporarily fix the driver 100.

[0046] Optionally, the tray 12 comprises a connecting plate 121, a supporting plate 122, and reinforcing ribs 123, the connecting plate 121 and the supporting plate 122 are L-shaped, the reinforcing ribs 123 are fixedly connected with the connecting plate 121 and the supporting plate 122 respectively, the connecting plate 121 is in sliding fit with the frame body 11, and the transmission assembly 3 drives the connecting plate 121 to slide relative to the frame body 11. In the embodiment, a plurality of reinforcing ribs 123 are arranged, and the reinforcing ribs 123 are arranged at intervals along the width direction Y of the frame body 11. The reinforcing ribs 123 can improve the stability of the connection between the connecting plate 121 and the tray 12, and effectively improve the maximum load of the tray 12.

[0047] Optionally, the roller assembly 2 comprises a connecting frame 21 and two rolling members 22 arranged at two ends of the connecting frame 21 along the width direction Y, and the connecting frame 21 is fixedly connected with the frame body 11. In the embodiment, the connecting frame 21 and the cross beam 1112 of the frame body 11 are detachably connected by bolts. In the embodiment, two rolling members 22 are arranged, so that when the rotation axes of the two rolling members 22 are collinear along the width direction Y of the frame body 11, the frame body 11 rotates around the rotation axes of the two rolling members 22, thereby adjusting the angle of the frame body 11 relative to the ground along the width direction Y.

[0048] Optionally, the rolling member 22 is a universal wheel with a brake function. In the embodiment, the universal wheel is conducive to the flexible movement of the trolley on the horizontal plane, and the universal wheel has a brake function. When the goods on the tray 12 need to be lifted along the vertical direction, the two universal wheels are stopped by braking, thereby preventing the goods on the goods table from moving in the horizontal plane. Specifically, when the frame body 11 rotates around the roller assembly 2, it is necessary to adjust the axial direction of the two universal wheels along the width direction Y, so that the frame body 11 can rotate around the roller assembly 2.

[0049] Optionally, the frame assembly 1 further comprises two side handles 15 arranged on the other side of the frame body 11 and fixedly connected with the two longitudinal beams 1111 respectively, so that the staff can conveniently hold the side handles 15 to facilitate pushing or pulling the trolley.

[0050] Optionally, the frame assembly 1 further comprises a top handle 16 arranged at one end of the frame body 11 away from the roller assembly 2 and fixedly connected with the two longitudinal beams 1111 respectively, so that the staff with a higher height can conveniently hold the top handle 16 to facilitate pushing or pulling the trolley.

[0051] For the specific use method of the trolley, exemplarily, when the staff needs to transport goods from A place to B place, and the goods do not need to be lifted at B place, the driver 100 is not needed to be installed on the trolley, the staff places the goods at A place on the tray 12, and directly pushes or pulls the trolley, so as to transport the goods at A place to B place. The above operation is repeated, so as to transport all the goods at A place to B place.

[0052] For example, when the worker needs to carry the goods from A to B, and the goods need to be lifted at B, the worker installs the driver 100 on the trolley, places the goods at A on the tray 12, and directly pushes or pulls the trolley to carry the goods at A to B, then lifts the goods on the tray 12 by the driver 100, and repeats the above operation to carry all the goods at A to B. Another method is that the worker places a driver 100 at B, places the goods at A on the tray 12, directly pushes or pulls the trolley to carry the goods at A to B, then installs the driver 100 at B on the trolley, lifts the goods on the tray 12 by the driver 100, and after the goods are lifted, removes the driver 100 and places it at B, and repeats the above operation to carry all the goods at A to B.

[0053] Obviously, the above embodiments of the present application are merely exemplary and are not intended to limit the embodiments of the present application. Based on the above description, those skilled in the art can make other different forms of changes or modifications. Here, it is not necessary and impossible to enumerate all the embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
