[0002] At present, the existing transport trolley can only realize the function of transporting items to a designated position. However, in actual use, after the items are transported to the designated position, they often need to be placed on a relatively high tabletop. The existing transport trolley requires manual handling of the items onto the relatively high tabletop, making the transportation very inconvenient and increasing the manual labor intensity. Especially for some heavy mechanical parts or heavy items, it is even more unfavorable for transportation. Therefore, a transport vehicle with a lifting function has been developed to lift the items to a relatively high position after transportation;

[0003] Chinese Patent Publication No. CN210163062U discloses a lifting transport vehicle, including a base frame, the base frame is a square frame structure; a transport tabletop, the transport tabletop is horizontally arranged, and the transport tabletop is located directly above the base frame in the vertical direction; a lead screw, one end of the lead screw is rotatably connected to a first bearing, the outer wall of the first bearing is fixedly connected to a fixing frame, and both ends of the fixing frame are fixedly connected to the side frames of the base frame.

[0027] Embodiment

[0028] Please refer to Figures 1-3 , the present utility model provides a technical solution: a lifting transport vehicle, including a base 1, with limiting grooves 13 opened on both sides of the base 1. A connecting block 14 is slidably connected to the limiting grooves 13. A pull rod 15 is rotatably connected to the surface of the connecting block 14. A handle 16 is fixedly installed on the surface of the pull rod 15. A positioning block 17 is fixedly installed on the side surface of the base 1. The positioning block 17 is located directly below the handle 16. The top end of the positioning block 17 is arc-shaped and is adapted to the bottom end of the pull rod 15 in size, which can fix the handle 16 and prevent the handle 16 from shaking. Universal wheels 2 are fixedly installed on the bottom surface of the base 1. An installation block 3 is fixedly installed on the top surface of the base 1. A hydraulic rod 4 is fixedly installed on the side surface of the installation block 3. The output end of the hydraulic rod 4 is installed with a cross bar 5. A slider 6 is fixedly installed on the surface of the cross bar 5. The slider 6 is located inside a chute 10 and is slidably connected to the chute 10. A fixed rod 7 is fixedly installed on the top surface of the base 1. A connecting rod 8 is arranged on the surface of the fixed rod 7. The top end of the connecting rod 8 is provided with a platform 9. Oblique plates 12 are fixedly installed on both sides of the platform 9. The oblique plates 12 are symmetrically distributed on both sides of the platform 9, which can further increase the stability of transporting items and prevent items from falling. A chute 10 is opened on the top surface of the base 1. A clamping mechanism 11 is arranged on the top surface of the platform 9;

[0029] The clamping mechanism 11 includes short blocks 1101 installed on both sides of the platform 9. Two groups of long rods 1102 penetrate through the inside of the short blocks 1101. A tension spring 1103 is sleeved on the surface of one group of long rods 1102. One end of the tension spring 1103 is fixedly connected to the surface of a limit block 1104, and the other end of the tension spring 1103 is fixedly connected to the surface of the short block 1101. One end of the two groups of long rods 1102 is fixedly installed with a limit block 1104, and the other end of the two groups of long rods 1102 is fixedly installed with a clamping plate 1105. An anti-slip pad 1106 is fixedly installed on the side of the clamping plate 1105 away from the short block 1101. The material of the anti-slip pad 1106 is nitrile rubber. The nitrile rubber material is soft and has anti-slip properties, and at the same time, the use cost is low, which can increase the friction between the clamping plate 1105 and the surface of the item and prevent the item from falling during transportation. The anti-slip pads 1106 are equally spaced on the surface of the clamping plate 1105.

[0030] Working principle: When in use, place the item on the top surface of the platform 9. Then, take out the handle 16 from the positioning block 17 to separate them. The handle 16 drives the pull rod 15 to move, and the pull rod 15 drives the connecting block 14 to slide within the limit groove 13. Pull the handle 16 again, and the handle 16 drives the base 1 to move. When the base 1 moves, it drives the universal wheels 2 on its bottom surface to roll, and then the item can be transported. When the item to be transported is small in volume, manually pull the limit block 1104. The limit block 1104 drives the long rod 1102 to move, and at the same time, the limit block 1104 pulls the tension spring 1103 to move. The long rod 1102 drives the clamping plate 1105 to move. Then, place the item to be transported on the top surface of the platform 9, and then release the hand pulling the limit block 1104. At this time, the tension spring 1103 loses the external force restriction. Due to its own pulling force, it drives the limit block 1104 to move in the reverse direction. The limit block 1104 drives the long rod 1102 to move at the same time until the surface of the clamping plate 1105 is in contact with the item. At this time, the anti-slip pad 1106 on the surface of the clamping plate 1105 is in contact with the item, which can increase the friction between the clamping plate 1105 and the surface of the item. At the same time, the clamping plate 1105 can clamp and position the item. Then, pull the handle 16 again to transport the item. When the item on the platform 9 needs to be lifted, activate the hydraulic rod 4. The hydraulic rod 4 drives the cross bar 5 to move. The cross bar 5 immediately drives the slider 6 to slide within the chute 10. At the same time, the cross bar 5 drives the connecting rod 8 to move. The connecting rod 8 drives the platform 9 to move upward until the platform 9 is lifted to an appropriate height. At this time, turn off the hydraulic rod 4 to load and unload the item on the platform 9. When the transport vehicle is no longer in use, after fixing the base 1, push the handle 16. The handle 16 drives the pull rod 15 to move, and the pull rod 15 drives the connecting block 14 to move inward. The connecting block 14 then slides within the limit groove 13 until the connecting block 14 moves to the innermost end of the limit groove 13. At this time, engage the handle 16 with the positioning block 17 to fix the handle 16.

[0031] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
