[0027] The technical solutions in 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, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figure 1-8 As shown in the embodiment of this application, a flexible combination of transport lifting trolleys is disclosed. When in use, multiple lifting trolleys can be flexibly selected and combined according to the size and quantity of goods to adjust the overall transport area and load-bearing capacity. It is suitable for the centralized transport of small goods and can also meet the collaborative handling of large and heavy goods, greatly improving the adaptability and versatility of transport.

[0029] Specifically, the lifting trolley includes a chassis 10, a traveling assembly 20, a lifting plate assembly 30, and a towing rod assembly 40. The chassis 10 is a frame structure used to support the overall structure. There are four traveling assemblies 20, located at the four corners of the chassis 10, used for the movement of the lifting trolley. The lifting plate assembly 30 is mounted on the chassis 10 and is used to carry and lift goods. A gooseneck block 11 is located at the front of the chassis 10, and the towing rod assembly 40 is mounted on the gooseneck block 11. The towing rod assembly 40 is used to pull the chassis 10 and drive the lifting plate assembly 30 to move.

[0030] The traveling assembly 20 includes a fixed base 21 located at the corner of the chassis 10. A fixed cylinder 22 is mounted on the fixed base 21, and a rotating frame 23 is rotatably mounted inside the fixed cylinder 22. A traveling wheel 24 with a horizontally arranged axle is rotatably mounted at the bottom of the rotating frame 23. The traveling wheel 24 is used for the ground movement of the entire lifting trolley. Through the rotatable connection between the fixed cylinder 22 and the rotating frame 23, the traveling wheel 24 can rotate 360 ​​degrees, which facilitates direction adjustment during travel. When turning, all four wheels can turn simultaneously to reduce the turning radius.

[0031] The lifting panel assembly 30 includes a lifting panel 31. A first Z-shaped block 32 and a second Z-shaped block 33, hinged in the middle to form an X-shape, are disposed between the chassis 10 and the lifting panel 31. The lifting panel 31 can be raised or lowered by the relative movement between the first Z-shaped block 32 and the second Z-shaped block 33. Specifically, a bearing rod 12 is rolled on the side of the chassis 10 near the towing rod assembly 40, and a fixing block 13 is disposed on the side away from the towing rod assembly 40. A rotating rod 14 is rotatably disposed on the fixing block 13. A fixing rod 34 is disposed on the bottom of the lifting panel 31 on the side away from the towing rod assembly 40. Sliding grooves 35 are formed by inwardly flanged edges on the left and right sides of the bottom of the lifting panel 31. The first Z-shaped block 32 is rotatably connected to the bearing rod 12 on the side near the towing rod assembly 40 and rotates with the fixing rod 34 on the side away from the towing rod assembly 40. The second Z-shaped block 33, near the towing rod assembly 40, has connecting shafts 36 extending to the left and right. These connecting shafts 36 roll into the sliding groove 35. The side of the second Z-shaped block 33 furthest from the towing rod assembly 40 is rotatably connected to the fixed block 13. This allows the first Z-shaped block 32 and the second Z-shaped block 33 to move horizontally within the base, thus driving the lifting panel 31 to rise and fall. This makes the lifting process of the lifting panel 31 more stable and uniform, ensuring the stability of the goods. Furthermore, first rollers 15 are installed at both ends of the bearing rod 12, rolling into the chassis 10. Second rollers 37 are installed at both ends of the connecting shaft 36, rolling within the sliding groove 35, further ensuring the stability of the scissor-like movement of the first Z-shaped block 32 and the second Z-shaped block 33.

[0032] Furthermore, limit blocks 16 are protruding on both sides of the chassis 10, and two limit holes 38 are correspondingly formed on the lifting panel 31. The cooperation between the limit blocks 16 and the limit holes 38 further prevents the lifting panel 31 from shifting during lifting, ensuring the stability of the goods during lifting. Several rotating rollers 39 are rotatably mounted on the lifting panel 31, which reduces the friction between the goods and the panel, facilitating the loading, unloading, and movement of goods.

[0033] Two gooseneck plates 17 are spaced apart at the front end of the gooseneck block 11, and a through hole 18 is provided in the gooseneck block 11. The towing rod assembly 40 includes a fixed sleeve 41 and a handle 42. The rear end of the fixed sleeve 41 is rotatably disposed between the two gooseneck plates 17, and the front end is disposed in the through hole 18. A top rod 43 is telescopically disposed inside the fixed sleeve 41 towards the chassis 10. The end of the top rod 43 abuts against the bearing rod 12. A connecting plate 44 is also provided on the cylinder wall of the fixed sleeve 41 between the two gooseneck plates 17. A lifting rod 45 is vertically slidably disposed on the fixed sleeve 41 behind the connecting plate 44. A connecting sleeve 46 is provided at one end of the handle 42. The connecting sleeve 46 is hinged to the top of the connecting plate 44 and the top of the lifting rod 45 respectively. By pressing the handle 42, the lifting rod 45 is raised and lowered, thereby driving the top rod 43 to extend and retract, which can push the bearing rod 12 to roll in the chassis 10, thereby driving the lifting panel 31 to rise and fall.

[0034] To enable flexible combination of multiple lifting trolleys, first connecting seats 50 are detachably installed on the left and right sides of the chassis 10, and second connecting seats 60 are detachably installed on the left and right sides of the gooseneck block 11. Specifically, positioning holes and mounting holes are provided on the left and right sides of the chassis 10 and the left and right sides of the gooseneck block 11. Positioning holes and mounting holes are correspondingly provided on the first connecting seats 50 and the second connecting seats 60. During installation, positioning is achieved by positioning pins, and then fixing is achieved by bolts. This facilitates the positioning and installation of the first connecting seats 50 and the second connecting seats 60 with the chassis 10 and the gooseneck block 11, respectively, and also facilitates the disassembly of the connecting seats when combination is not required or on the side where combination is not required.

[0035] A first connecting sleeve 51 arranged horizontally outward is provided on the first connecting seat 50, and a second connecting sleeve 61 arranged horizontally outward is provided on the second connecting seat 60. Both the first connecting sleeve 51 and the second connecting sleeve 61 have internal threads. The two first connecting sleeves 51 and the two second connecting sleeves 61 located on the inner side of adjacent lifting trolleys are connected by a first connecting rod 52 and a second connecting rod 62, respectively, connecting multiple lifting trolleys into a row. Specifically, the first connecting rod 52 includes a first connecting block 53 and first lead screws 54 located at both ends of the first connecting block 53. The first lead screws 54 at both ends are threadedly connected to the corresponding first connecting sleeve 51. The second connecting rod 62 includes a second connecting block 63 and second lead screws 64 located at both ends of the second connecting block 63. The second lead screws 64 at both ends are threadedly connected to the corresponding second connecting sleeve 61. A first threaded hole is radially through the center of the first connecting block 53, and a second threaded hole is radially through the center of the second connecting block 63. A connecting screw 70 is provided between the first connecting block 53 and the second connecting block 63. The two ends of the connecting screw 70 are threaded into the first threaded hole and the second threaded hole, respectively, thereby connecting the first connecting block 53 and the second connecting block 63 through the connecting screw 70, improving the stability of the connection between adjacent lifting trolleys. A connecting bracket 65 is also provided on the side of the second connecting block 63 away from the first connecting rod 52, and a long handle 66 is rotatably mounted on the connecting bracket 65. The long handle 66 is positioned between the two lifting trolleys for easy operation. When multiple lifting trolleys are connected side-by-side, the connecting bracket 65 and the long handle 66 can be positioned appropriately as needed to facilitate operation of the assembly or simultaneous operation by multiple people.

[0036] A further configuration includes a detachable third connecting seat 80 on the rear side of the chassis 10. The third connecting seat 80 has horizontally outwardly arranged third connecting sleeves 81. When arranged in two rows, the two third connecting sleeves 81 are connected between two opposing lifting trolleys via a third connecting rod 82. When handling large goods, the two rows of lifting trolleys can be placed opposite each other, and then connected to the third connecting sleeves 81 on the rear side of the chassis 10 via the third connecting rod 82, thereby increasing the carrying area of ​​the trolleys and facilitating the handling of large items.
