One end of the connecting portion 32 is connected to the leg assembly 31, and the other end of the connecting portion 32 is configured to engage with the sleeve portion 23. The moving assembly 3 is used to drive the pole assembly 1 to move on a plane. The connector 4 is configured to pass through the sleeve portion 23 and the connecting portion 32 to realize a detachable connection between the moving assembly 3 and the base 2.
[0035] This application provides a transport vehicle that uses a movable component 3 and a base 2 for connection, and a connector 4 passes through the base 2 and the movable component 3 to achieve a detachable connection between the base 2 and the movable component 3. During transportation, the connector 4 is removed from the base 2 and the movable component 3, and then the movable component 3 is detached from the base 2, which can reduce the space occupied by the transport vehicle and reduce packaging and transportation costs.
[0036] Specifically, the upright assembly 1 has a slender structure, thereby further reducing the space occupied by the transport vehicle. Furthermore, the base 2 and the upright assembly 1 are detachably and fixedly connected.

The connecting rods 22 are inclined relative to the upright assembly 1. One end of the connecting rod 22 is connected to one end of the support rod 21, and the other end of the connecting rod 22 is connected to the side of the upright assembly 1. The connecting rods 22, the upright assembly 1, and the support rod 21 form a triangular structure to enhance the connection stability between the upright assembly 1 and the base 2.
[0040] Specifically, both the support rod 21 and the connecting part 32 are square tube structures, which can be quickly installed and replaced.
[0041] refer to Figure 1 and Figure 2 There are two movable components 3. Each end of the support rod 21 has a sleeve portion 23, and the two movable components 3 are respectively sleeved onto the ends of the support rod 21 via connecting portions 32. There are at least two connecting pieces 4, with each movable component 3 corresponding to at least one connecting piece 4. In this embodiment, there are two connecting pieces 4.
[0042] Specifically, the sleeve part 23 is formed by axially hollowing the support rod 21.
[0043] refer to Figure 1 The outrigger assembly 31 includes a first outrigger 33, a second outrigger 34, a first rotating wheel 35, and a second rotating wheel 36. The first outrigger 33 and the second outrigger 34 are connected. The first rotating wheel 35 is rotatably disposed at the bottom of the first outrigger 33, and the second rotating wheel 36 is rotatably disposed at one end of the second outrigger 34. One end of the connecting portion 32 is disposed at the connection between the first outrigger 33 and the second outrigger 34. Specifically, the connecting portion 32 is perpendicularly disposed to the first outrigger 33. In this embodiment, the two second outriggers 34 are arranged in parallel, and the connecting portion 32 is perpendicular to the second outriggers 34.
[0044] Specifically, to further reduce the space occupied by the transport vehicle, the first leg 33 and the second leg 34 are detachably connected.
[0045] refer to Figures 5 to 7 The transport vehicle also includes a carrying device 5, which is detachably mounted on the side of the upright assembly 1. The carrying device 5 is used to carry items and can move along the axial direction of the upright assembly 1.
[0046] refer to Figures 1 to 4The upright assembly 1 includes a fixing member 11, a sliding member 12, and a driving member 13. The middle part of the support rod 21 is fixedly connected to the bottom of the fixing member 11, and the fixing member 11 is perpendicular to the support rod 21. One end of the connecting rod 22 is connected to one end of the support rod 21, and the other end of the connecting rod 22 is connected to the side of the fixing member 11. A main channel 111 is provided inside the fixing member 11, a first opening 112 is provided on the side wall of the fixing member 11, and a second opening 113 is provided at the top of the fixing member 11. The first opening 112 and the second opening 113 are connected. The sliding member 12 is disposed in the main channel 111. The sliding member 12 has a first side wall 121, which is located in the first opening 112. The bearing device 5 is detachably disposed in the first side wall 121. The driving member 13 is disposed inside the sliding member 12, and the top of the driving member 13 is connected to the top of the sliding member 12. The driving member 13 can extend and retract along its own axis, thereby driving the sliding member 12 and the bearing device 5 to move up and down along the main channel 111.
[0047] Specifically, both the fixing member 11 and the sliding member 12 are hollow structures, and are roughly rectangular in shape.
[0048] Specifically, a second opening 113 is provided at the top of the fixing member 11, which will not hinder the upward movement of the sliding member 12.
[0049] refer to Figure 3 and Figure 4 The fastener 11 includes a main body 114 and two flanges 115. The main body 114 defines a main channel 111. The two flanges 115 are disposed on two opposite sidewalls of the main body 114. The two flanges 115 define two secondary channels 116 respectively. The secondary channels 116 are connected to the main channel 111 and extend along the length direction of the main channel 111.
[0050] Specifically, the flange 115 is rectangular.
[0051] refer to Figure 2 The pole assembly 1 also includes at least two bearings 14, which are respectively disposed on opposite side walls of the sliding member 12. Each bearing 14 is disposed in a corresponding secondary channel 116, thereby attaching the sliding member 12 to the fixing member 11. The bearings 14 enable the sliding member 12 to move up and down along the main channel 111 within the fixing member 11.
[0052] In this embodiment, there are four bearings 14.
[0053] The pole assembly 1 also includes a buffer 141, which covers the outer ring of the bearing 14, and each bearing 14 is covered with a buffer 141.
[0054] Specifically, the material of the buffer 141 is nylon.
[0055] When attachments are suspended from the front of the main body 114 and heavy objects are loaded, the center of the heavy objects is on the outside of the main body 114, causing the main body 114 to be subjected to an overturning moment. This moment is transmitted to the contact surfaces of the four bearings and the secondary channel 116. When the outer ring of the bearing 14 is in direct contact with the surface of the secondary channel 116, the contact stress on the contact surface between the bearing 14 and the secondary channel 116 is very high due to the high hardness of the outer ring material, resulting in stress concentration. After repeated rolling and crushing by the bearing 14, the secondary channel 116 will fail due to wear, deformation, tearing, etc. This application adds a nylon sleeve to the outer ring of the bearing 14 as a buffer to avoid direct contact between the bearing 14 and the secondary channel 116. Since the hardness of the nylon material is much lower than that of the bearing outer ring, the contact stress on the secondary channel 116 is greatly improved, thus preventing failure.
[0056] refer to Figure 1 , Figure 2 and Figure 6 The first sidewall 121 has multiple interfaces 122, which are spaced apart along the height direction of the first sidewall 121. The carrying device 5 includes a carrying part 51 and a plug-in part 52, which are connected to each other. The carrying part 51 is used to load items, and the plug-in part 52 is configured to be inserted into the interface 122 to realize the detachable connection between the carrying device 5 and the sliding member 12.
[0057] In this embodiment, two spaced-apart interfaces 122 form a group, and multiple groups of interfaces 122 are spaced apart along the height direction of the first sidewall 121. The accessory, i.e., the support device 5, can be quickly installed through the interfaces on the slider 12, and by providing multiple groups of interfaces 122, the installation position of the support device 5 can be adjusted according to the required height.
[0058] Specifically, the load-bearing unit 51 includes a drum gripper, a load-bearing plate, and a forklift component. With the standard interface 122, different load-bearing units 51 can be used to achieve different functions and are suitable for heavy object handling in different work scenarios.
[0059] Another embodiment, refer to Figure 5When the bearing part 51 is an oil drum gripper, the bearing device 5 is used to grip the oil drum. Two first legs 33 are arranged in parallel, and two second legs 34 are symmetrically arranged on both sides of the upright assembly 1. The distance between the ends of the two second legs 34 with the second rotating wheels 36 is greater than the distance between the ends of the two second legs 34 and the connecting part 32. The shape formed by the two second legs 34 and the support rod 21 is approximately an isosceles trapezoid. The first rotating wheels 35 and the second rotating wheels 36 are of the same specification. This structure has a wider force-bearing surface, preventing the equipment from tilting or becoming unbalanced, thereby ensuring safety and accuracy during the oil drum gripping process.
[0060] refer to Figure 7 When the bearing part 51 is a bearing plate, it is used to load heavy objects or pallets. The two first legs 33 are arranged in parallel, the two second legs 34 are arranged in parallel, and the first wheel 35 and the second wheel 36 are of the same specification and model.
[0061] refer to Figure 6 When the load-bearing part 51 is a forklift component, it is used to load cement or fertilizer. Two first legs 33 are arranged in parallel, and two second legs 34 are arranged in parallel. The diameter of the second wheel 36 is smaller than the diameter of the first wheel 35. The smaller diameter of the second wheel 36 ensures a lower center of gravity. This design helps reduce the risk of tilting when forking or moving heavy objects. The smaller second wheel 36 allows for greater maneuverability when turning, especially in confined spaces, providing better steering capability.
[0062] refer to Figure 1 and Figure 2 The upright assembly 1 also includes a handle 15, which is disposed on the side wall of the fixing member 11 away from the first opening 112. The handle 15 facilitates the movement of the transport vehicle by the staff.
[0063] refer to Figure 1 , Figure 2 and Figure 3 The driving component 13 is a foot-operated hydraulic cylinder. The driving component 13 includes a foot pedal 131 and a lifting cylinder 132. The lifting cylinder 132 is located inside the main channel 111. The foot pedal 131 extends out of the main channel 111. The side wall of the main body 114 has a notch 117 for avoiding the foot pedal 131.
[0064] Specifically, the sliding member 12 is raised or lowered by stepping on the foot pedal 131.
[0065] The pallet truck described in this application, through a standard interface and with different accessories or outriggers, can achieve different functions and is suitable for heavy-duty handling in various work scenarios. Furthermore, the detachable outriggers and accessories can significantly reduce packaging volume.
[0066] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
