Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides a transport vehicle. Figure 1 A schematic diagram of the transport vehicle structure in an embodiment of the present invention is shown. Figure 1 The transport vehicle includes a frame 1, a hoisting mechanism 2, and a traveling mechanism 3. The frame 1 has a U-shaped clamp 11 on the surface where the transported object is placed. The hoisting mechanism 2 passes through the frame 1 and is located on both sides of the U-shaped clamp 11. The traveling mechanism 3 is located on the side of the frame 1 away from the U-shaped clamp 11. The transported object is placed inside the U-shaped clamp 11 and moves through the cooperation of the hoisting mechanism 2 and the traveling mechanism 3.

[0026] Specifically, the frame 1 includes a handlebar 14 and an axle 12. The handlebar 14 is located on one side of the axle 12. The traveling mechanism 3 includes a guide wheel 32 and a traveling wheel 31. The guide wheel 32 is located on the axle 12 on the side away from the handlebar 14. The traveling wheel 31 is located at one end of the guide wheel 32 and on the axle 12 on the side away from the U-shaped clamp 11.

[0027] In this embodiment of the invention, in order to save effort during transportation, the hoisting mechanism 2 and the axle 12 are connected by three sets of hinges. By stepping on the pedal 26, the force is transmitted to the hook 21 using the lever principle, thereby lifting the transported object and enhancing the applicability of the transport vehicle.

[0028] Specifically, the hoisting mechanism 2 includes a boom 23, a pedal 26, a linkage mechanism, and a pin 28. The boom 23 and the pin 28 are located on both sides of the U-shaped clamp 11. The pedal 26 is hinged to the side of the axle 12 near the guide wheel 32. The linkage mechanism is located on the side of the axle 12 away from the U-shaped clamp 11 and is sequentially hinged to the boom 23, the pedal 26, and the pin 28. The pedal 26 is used to hinge and rotate during transport so that the transported object is lifted off the ground and hoisted onto the boom 23.

[0029] Specifically, in order to increase the safety of the transported goods during transportation and prevent the hook 21 from coming loose, the boom 23 passes through the axle 12 and is hinged to the axle 12 body. The boom 23 is located on the side of the axle 12 near the handle 14. The axle 12 has a socket, and the pin 28 is used to insert into the socket to support the transported goods when the pedal 26 is hinged and rotated.

[0030] Specifically, the hoisting mechanism 2 also includes a hook 21 and a chain 22. The hook 21 is set below the boom 23 via the chain 22. A hoisting hole 41 is opened on the object to be transported near the hook 21. The object to be transported is hoisted onto the boom 23 through the hoisting hole 41 and the hook 21.

[0031] Specifically, the linkage mechanism includes a first link 24, a second link 25, and a third link 27. The second link 25 and the third link 27 are hinged together by a hinge shaft 29 provided on the axle 12. The first link 24 is hinged to the boom 23 at the end away from the hinge shaft 29. The second link 25 is hinged to the pedal 26 at the end away from the hinge shaft 29 and the third link 27. The third link 27 is hinged to the pin 28 on the side away from the pedal 26.

[0032] Specifically, to prevent the gripper from slipping during handling, the handle 14 has spiral patterns.

[0033] Specifically, to prevent the risk of stepping into the air and causing danger, an arc-shaped groove is provided at the end of the pedal 26 away from the axle 12.

[0034] Specifically, the axle 12 is provided with a support leg 13 away from the U-shaped clamp 11, and the support leg 13 is located on the side of the axle 12 near the handle 14.

[0035] Specifically, in order to enhance the stability of the placement and movement of the transport vehicle in this embodiment of the invention, two of each of the outriggers 13, guide wheels 32, traveling wheels 31 and U-shaped clamps 11 are provided. Two outriggers 13, two guide wheels 32 and two traveling wheels 31 are symmetrically arranged on both sides of the bottom of the axle 12, and two U-shaped clamps 11 are respectively arranged around the transported object.

[0036] In this embodiment of the invention, in order to better illustrate the implementation process of the transport vehicle of the present invention, the transported object is selected from a high-pressure gas cylinder (a gas cylinder with a working pressure equal to or greater than 8MPa). It should be noted that the high-pressure gas cylinder in this embodiment of the invention is only an example. In actual production applications, the transport of heavy objects is within the protection scope of this invention.

[0037] In this embodiment of the invention, the handling process of the high-pressure gas cylinder 4 is also described in detail. Figure 2 This diagram illustrates the alignment structure between the transport vehicle and the high-pressure gas cylinder in an embodiment of the present invention. Figure 2 In the middle, a lifting hole 41 is opened on the high-pressure gas cylinder 4. The operator holds the handle 14 and moves the trolley to the position of the high-pressure gas cylinder 4 through the traveling wheels 31. The trolley axle 12 is placed vertically on the ground and moves towards the high-pressure gas cylinder 4 through the guide wheels 32, so that the body of the high-pressure gas cylinder 4 is in the U-shaped clamp 11, realizing the alignment operation.

[0038] In this embodiment of the invention, two U-shaped clamps 11 are provided. It should be noted that the limitation on the number of U-shaped clamps 11 in this embodiment of the invention is only an example. In actual application, the number of U-shaped clamps 11 can be adaptively adjusted according to the size and weight of the high-pressure gas cylinder 4.

[0039] After the alignment operation is completed, the high-pressure gas cylinder 4 will be lifted. Figure 3 A schematic diagram of a high-pressure gas cylinder lifting operation in an embodiment of the present invention is shown. Figure 3 In the process, the hook 21 is hooked into the lifting hole 41 on the high-pressure gas cylinder 4. The foot steps on the pedal 26, and under the action of the lever, the hinge of the pedal 26 rotates, causing the boom 23 to lift up. This moves the first link 24, the second link 25, and the third link 27. The pin 28 is inserted into the socket on the axle 12. At this time, the high-pressure gas cylinder 4 is raised under the action of the boom 23. The pin 28 inserted into the socket supports the bottom of the high-pressure gas cylinder 4, providing support for the high-pressure gas cylinder 4. Under the traction of the first link 24, the second link 25, and the third link 27, the boom 23 and the pin 28 restrain each other, realizing the lifting operation.

[0040] In this embodiment of the invention, the length of the suspension chain 22 can be adaptively adjusted according to the size of the high-pressure gas cylinder 4.

[0041] After the high-pressure gas cylinder 4 is lifted, the process also includes flipping the high-pressure gas cylinder 4 over. Figure 4 A schematic diagram of the high-pressure gas cylinder tipping operation in an embodiment of the present invention is shown. Figure 4 In the process, the operator pulls the handle 14 towards the side closer to the ground, and the tilt angle of the axle 4 changes accordingly, so that the high-pressure gas cylinder 4 is placed on the transport vehicle, kept stable, and the flipping operation is realized.

[0042] After high-pressure gas cylinder 4 is flipped, further transfer operations will be carried out. Figure 5 A schematic diagram of the high-pressure gas cylinder walking operation in an embodiment of the present invention is shown. Figure 5 In the middle, the operator pushes the handle 14 to maintain balance. At this time, the guide wheel 32 is lifted off the ground and moves with the help of the walking wheel 31 under the action of human power, so as to carry the high-pressure gas cylinder to the destination and realize the walking operation.

[0043] After reaching the designated position, the high-pressure gas cylinder 4 is placed stably using the outriggers 13. When it is necessary to remove the high-pressure gas cylinder 4, the axle 12 is rotated to a position perpendicular to the ground (see relevant diagram). Figure 3 As shown, lift the pedal 26 upwards so that the pin 28 is pulled out of the socket. Under the action of the first link 24, the second link 25 and the third link 27, the boom 23 rotates counterclockwise until the bottom of the high-pressure gas cylinder 4 touches the ground. At this time, remove the hook 21 from the lifting hole 41 so that the high-pressure gas cylinder 4 is placed in the required position, and the transportation is completed.

[0044] The transport vehicle of the present invention utilizes the lever principle to design a lifting mechanism on the transport vehicle, which saves time and effort, improves efficiency, reduces transport costs, and enables the transport of heavy objects under specific conditions.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
