Description

Technical Field

[0001] This utility model relates to the technical field of cargo transportation lifting devices, and more particularly to a cargo transportation lifting device. Background Technology

[0002] In the logistics industry, trucks are commonly used for cargo transportation, and their cargo compartments are designed with a certain height to increase loading capacity and transportation efficiency. However, for heavy goods, traditional manual loading and unloading methods have significant limitations, such as high labor intensity, low efficiency, and high safety risks, and lack of stability when hoisting pipes.

[0003] Chinese patent publication number CN221370170U discloses a cargo transport lifting device, belonging to the field of cargo transport technology. This cargo transport lifting device includes a bracket, lifting rings, a slider, a threaded rod, and a support arm. Two lifting rings are fixed to the top surface of the bracket. One end of the support arm is fixed to one side of the slider. In use, the threaded rod is rotated, causing it to pass through a threaded hole and enter the slider, thus installing the support arm onto the bracket. Then, the lifting rings are used to install the bracket onto the lifting equipment, enabling the transport of pipes or wires. The cargo transport lifting device has an adjustable structure, meaning the number of support arms and the distance between them can be adjusted according to the size of the pipes or wires, ensuring that more pipes or wires can be transported at once. This improves the transport efficiency of pipes or wires of the same batch and provides a better user experience.

[0004] Existing cargo transport lifting devices suffer from several drawbacks. Simply fitting the pipe onto a columnar support arm allows the pipe to easily sway and collide with the support arm during lifting and movement, resulting in damage and insufficient stability. To overcome these disadvantages, this invention provides a cargo transport lifting device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a cargo transportation lifting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cargo transport lifting device, comprising a base, a U-shaped frame fixedly connected to the top surface of the base, first sliding grooves symmetrically formed on both sides of the U-shaped frame, a guide rod disposed within the U-shaped frame, connecting blocks symmetrically fixedly connected to both sides of the guide rod, the connecting blocks being slidably connected to corresponding first sliding grooves, a second sliding groove formed on the bottom side of the guide rod, a slider slidably connected within the second sliding groove, a fixing rod fixedly connected to the bottom side of the slider, and a plurality of lifting rods evenly fixedly connected to the bottom side of the fixing rod. The rod has a third sliding groove on its bottom side, and a clamping frame is symmetrically slidably connected in the third sliding groove. Several hollow sleeves are evenly fixedly connected to the bottom inner side of the clamping frame. Moving rods are symmetrically arranged vertically inside the sleeves. Several insert rods are fixedly connected to the opposite sides of the moving rods. Through holes are opened on the sleeves at the positions corresponding to the insert rods. One end of the insert rod extends out of the sleeve through the corresponding through hole and is fixedly connected to an abutment block. One end of the sleeve extends out of the clamping frame and is fixedly connected to a U-shaped frame. A moving component for driving the moving rod to move is provided inside the U-shaped frame.

[0007] Furthermore, a first one-way screw is rotatably connected within the first groove, and the connecting block is threadedly connected to the corresponding first one-way screw. The bottom end of the first one-way screw extends to the bottom side of the top plate of the base and is fixedly connected to a driven bevel gear. A rotating shaft is rotatably connected within the base, and a driving bevel gear is fixedly connected to each position on the rotating shaft corresponding to the driven bevel gear. The driving bevel gear meshes with the corresponding driven bevel gear. A first motor is fixedly connected to the outside of the base, and the output end of the first motor is fixedly connected to the rotating shaft.

[0008] Furthermore, a second one-way screw is rotatably connected inside the second groove, the slider is threadedly connected to the second one-way screw, a second motor is fixedly connected to the outside of the guide rod, and the output end of the second motor is fixedly connected to the second one-way screw.

[0009] Furthermore, a first bidirectional screw is rotatably connected within the third slide groove. The first bidirectional screw has symmetrically formed threaded grooves with opposite directions of rotation. The clamping frame engages with the corresponding threaded grooves on the first bidirectional screw. A third motor is fixedly connected to the outside of the lifting rod, and the output end of the third motor is fixedly connected to the first bidirectional screw.

[0010] Furthermore, the moving component includes a second bidirectional screw, which is rotatably connected to the housing. The second bidirectional screw has symmetrically arranged threaded grooves with opposite directions of rotation. One end of the moving rod extends into the housing and engages with the corresponding threaded groove on the second bidirectional screw. A limiting rod is fixedly connected inside the housing, and all moving rods are slidably connected to the limiting rod.

[0011] Furthermore, a fourth motor is fixedly connected to the top side of the spiral frame at the position corresponding to the second bidirectional screw, and the output end of the fourth motor is fixedly connected to the second bidirectional screw.

[0012] The beneficial effects of this utility model are:

[0013] When in use, this cargo lifting device has the following advantages:

[0014] 1. In this solution, a clamping frame, sleeve, moving rod, insertion rod, through hole, abutment block, return frame, second bidirectional screw, and limiting rod are provided. After the symmetrical sleeves on both sides are inserted into the inside of the two ends of the pipe, the fourth motor drives the second bidirectional screw to rotate, thereby driving the symmetrical moving rods to move in the opposite direction along the limiting rod. The length of the insertion rod extending out of the sleeve is adjusted, and several symmetrical abutment blocks abut against the inner wall of the pipe to radially limit the pipe. This prevents the pipe from swaying and colliding with the sleeve during the movement of the lifting rod, thus improving safety and the stability of pipe lifting. At the same time, it can be adjusted according to the pipe diameter to improve applicability.

[0015] 2. In this scheme, by setting up a fixed rod, a hanging rod, a third sliding groove, and a first bidirectional screw, pipes of the same length are placed under the same hanging rod and corresponding to the position of the sleeve. The third motor drives the first bidirectional screw to rotate, thereby driving the clamping frames on both sides to move towards each other. The symmetrical sleeves on both sides are inserted into the inside of both ends of the pipe. Several hanging rods are set up to facilitate the simultaneous loading of pipes of different lengths.

[0026] like Figure 1-6 As shown, a cargo transport lifting device includes a base 1. A U-shaped frame 2 is fixedly connected to the top surface of the base 1. First sliding grooves 3 are symmetrically opened on both sides of the U-shaped frame 2. A guide rod 5 is arranged inside the U-shaped frame 2. Connecting blocks 6 are symmetrically fixedly connected to both sides of the guide rod 5. The connecting blocks 6 are slidably connected to the corresponding first sliding grooves 3. A second sliding groove 11 is opened on the bottom side of the guide rod 5. A slider 14 is slidably connected in the second sliding groove 11. A fixing rod 15 is fixedly connected to the bottom side of the slider 14. A plurality of lifting rods 16 are evenly fixedly connected to the bottom side of the fixing rods 15. A third sliding groove 17 is opened on the bottom side of the lifting rods 16. A clamping frame 19 is symmetrically slidably connected within the three sliding grooves 17. Several hollow sleeves 21 are uniformly fixedly connected to the inner side of the bottom end of the clamping frame 19. Moving rods 22 are symmetrically arranged inside the sleeves 21. Several insert rods 23 are fixedly connected to the opposite side of the moving rods 22. Through holes 24 are opened on the sleeves 21 at the positions corresponding to the insert rods 23. One end of the insert rod 23 extends to the outside of the sleeve 21 through the corresponding through hole 24 and is fixedly connected to an abutment block 25. One end of the sleeve 21 extends to the outside of the clamping frame 19 and is fixedly connected to a U-shaped frame 26. A moving component for driving the moving rods 22 to move is provided inside the U-shaped frame 26.

[0027] like Figure 1 , 2As shown, a first one-way screw 4 is rotatably connected inside the first groove 3. The connecting block 6 is threadedly connected to the corresponding first one-way screw 4. The bottom end of the first one-way screw 4 extends to the bottom side of the top plate of the base 1 and is fixedly connected to a driven bevel gear 7. A rotating shaft 8 is rotatably connected inside the base 1. A driving bevel gear 9 is fixedly connected to the rotating shaft 8 at the position corresponding to the driven bevel gear 7. The driving bevel gear 9 meshes with the corresponding driven bevel gear 7. A first motor 10 is fixedly connected to the outside of the base 1. The output end of the first motor 10 is fixedly connected to the rotating shaft 8. When the first motor 10 is started, it drives the rotating shaft 8 and the driving bevel gear 9 to rotate, thereby driving the driven bevel gear 7 meshing with the driving bevel gear 9 to rotate synchronously, thereby driving the first one-way screw 4 on both sides to rotate synchronously, thereby driving the connecting block 6 and the guide rod 5 to rise and fall as a whole.

[0028] like Figure 1 , 2 As shown, a second one-way screw 12 is rotatably connected inside the second slide groove 11. The slider 14 is threadedly connected to the second one-way screw 12. A second motor 13 is fixedly connected to the outside of the guide rod 5. The output end of the second motor 13 is fixedly connected to the second one-way screw 12. When the second motor 13 is started, the second one-way screw 12 is driven to rotate, thereby driving the slider 14, the fixed rod 15, and several hanging rods 16 to move horizontally along the direction of the second slide groove 11.

[0029] like Figure 3 , 4 As shown, a first bidirectional screw 18 is rotatably connected inside the third slide groove 17. The first bidirectional screw 18 has symmetrically opened threaded grooves with opposite directions of rotation. The clamping frames 19 respectively mesh with the corresponding threaded grooves on the first bidirectional screw 18. A third motor 20 is fixedly connected to the outside of the lifting rod 16. The output end of the third motor 20 is fixedly connected to the first bidirectional screw 18. When the third motor 20 is started, the first bidirectional screw 18 is rotated, which in turn drives the clamping frames 19 on both sides to move towards each other. The symmetrical sleeves 21 on both sides are inserted into the two ends of the pipe for lifting.

[0030] like Figure 3 , 5As shown in Figure 6, the moving assembly includes a second bidirectional screw 27, which is rotatably connected to the housing 26. The second bidirectional screw 27 has symmetrically arranged threaded grooves with opposite directions of rotation. One end of the moving rod 22 extends into the housing 26 and engages with the corresponding threaded groove on the second bidirectional screw 27. A limit rod 28 is fixedly connected inside the housing 26, and the moving rod 22 is slidably connected to the limit rod 28. A fourth motor 29 is fixedly connected to the top side of the housing 26 at the position corresponding to the second bidirectional screw 27. The output end of the motor 29 is fixedly connected to the second bidirectional screw 27. When the fourth motor 29 is started, the second bidirectional screw 27 is driven to rotate, which in turn drives the vertically symmetrical moving rod 22 to move in the opposite direction along the limiting rod 28. The length of the insert rod 23 extending out of the sleeve 21 is adjusted until the vertically symmetrical abutting blocks 25 abut against the inner wall of the pipe, thereby radially limiting the pipe and preventing damage caused by the pipe swaying and colliding with the sleeve 21 during the movement of the lifting rod 16, thus improving safety and the stability of the pipe placement.

[0031] Working principle: In use, the first motor 10 is started, which drives the rotating shaft 8 and the driving bevel gear 9 to rotate, thereby driving the driven bevel gear 7, which meshes with the driving bevel gear 9, to rotate synchronously. This, in turn, drives the first one-way screws 4 on both sides to rotate synchronously, thereby driving the connecting block 6 and the guide rod 5 to descend as a whole. The pipe is placed on one side of the U-shaped frame 2 on the base 1. Pipes of the same length are placed under the same lifting rod 16 and corresponding to the position of the sleeve 21. The third motor 20 is started, which drives the first double-direction screw 18 to rotate, thereby driving the clamping frames 19 on both sides to move towards each other. The symmetrical sleeves 21 on both sides are inserted into the two ends of the pipe. Several lifting rods 16 are set to facilitate the simultaneous loading of pipes of different lengths. The fourth motor 29 is started, which drives the second double-direction screw 27 to rotate, thereby driving the symmetrically moving rods 22 to move along the limit rod 2. 8. Move in the opposite direction and adjust the length of the insertion rod 23 extending out of the sleeve 21 until the several symmetrical abutment blocks 25 abut against the inner wall of the pipe, thereby radially limiting the pipe and preventing damage caused by the pipe swaying and collision with the sleeve 21 during the movement of the lifting rod 16. This improves safety and the stability of the pipe hoisting. At the same time, it can be adjusted according to the pipe diameter to improve applicability. After loading is completed, start the first motor 10 to drive the guide rod 5 and the fixed rod 15 to rise as a whole. Start the second motor 13, thereby driving the second one-way screw 12 to rotate, thereby driving the slider 14, the fixed rod 15, and several lifting rods 16 to move horizontally along the direction of the second slide groove 11. Move the fixed rod 15, several lifting rods 16 and the hoisted pipe to the loading carriage outside the base 1, and then unload the pipe. All motors are electrically connected to an external power supply.
