The left side There are two through openings on the side surface of the plate 2 and the side surface of the right side plate 3 , and side wheels 10 are installed in each opening.

In this embodiment, when using the trolley, firstly, weld a load-carrying body frame for transporting articles on the upper bracket 1, and place the articles to be transported in the load-carrying body frame, preferably the top surface of the load-carrying body frame The frame structure with the opening, that is, in the process of transportation, the articles to be transported in the load body will not fall, which ensures the safety of the articles to be transported. In the specific transportation process, the trolley can be manually pushed by people, giving the trolley an external thrust to force the trolley to move, and also through the driving mechanism (not shown in the figure) provided on the carrier frame. To provide the power to move the trolley, the drive mechanism includes a servo motor that provides rotational power, and components such as gears, belts, and racks for transmission. The drive mechanism can drive the upper wheel 6 to rotate, and does not specifically limit the The specific structure of the driving mechanism is as long as it is a driving mechanism that can drive the trolley to roll and walk on the H-shaped steel 12, or the upper wheel 6 can be directly driven by the servo motor to rotate, and the two upper wheels 6 rotate on the top of the H-shaped steel 12. During the surface rolling process, the four lower wheels 8 cooperate with the H-beam 12 to roll on the lower surface of the top. Similarly, the four side wheels 10 also cooperate with the H-beam 12 to roll on the top side of the H-beam 12, so that the entire trolley is formed on the H-beam. Rolling on the 12, the items to be transported can be transported from one side of the H-beam 12 to the other side. The upper wheel 6, the side wheel 10 and the lower wheel 8 roll and walk on the top of the H-shaped steel 12, which ensures that the trolley can roll on the top, the side and the bottom of the H-shaped steel 12, which not only improves the stability of the trolley during transportation The stability and safety also make the rolling transportation of the trolley smoother. It should also be noted that the function of the hinge shaft 4 is that when the H-beam 12 is deformed, the load frame can be fine-tuned within a certain range of motion, and the unilateral adjustment angle is preferably within 3mm to make the load more stable.

Further, the two upper wheels 6 are arranged horizontally and parallelly, and the two ends of each upper wheel 6 are respectively fixedly connected with upper wheel axles 7, wherein the two upper wheel axles 7 penetrate through the left side plate 2 and are rotatably connected with the left side plate 2, and the other two The axles 7 penetrate through the right side plate 3 and are rotatably connected with the right side plate 3 .

In this embodiment, the two upper wheels 6 are on the same horizontal plane, and the driving mechanism can drive the two upper wheels 6 to move at the same time or one of the upper wheels 6 to rotate. They are rotated in the left side plate 2 and the right side plate 3 respectively.

Further, the two lower wheels 8 are both rotatably connected to the left side plate 2 through the lower axle 9 , and the other two lower wheels 8 are rotatably connected to the right side plate 3 through the lower axle 9 .

Further, each side wheel 10 is rotatably installed in each opening through a side wheel axle 11 .

In this embodiment, the side wheel 10 rotates in the opening through the side wheel shaft 11 during the rolling process.

Further, a connecting plate 5 is fixedly connected between the inner side surface of the left side plate 2 and the inner side surface of the right side plate 3 , and the connecting plate 5 is located between the hinge support shaft 4 and the two upper wheels 6 .

In this embodiment, the left side plate 2 and the right side plate 3 are connected into a whole by the connecting plate 5 by welding, and the connecting plate 5 plays a supporting role and enhances the stability of the trolley for carrying and transporting.

Further, the left side plate 2 , the connecting plate 5 and the right side plate 3 are integrally formed.

In this embodiment, the left side plate 2 , the connecting plate 5 and the right side plate 3 can be directly designed to be integrally formed during the installation or processing of the trolley, so that the trolley itself has the connecting plate 5 for support.

The working principle and use process of the present invention: after the present invention is installed, when using the trolley, firstly weld the load-carrying body frame for transporting articles on the upper bracket 1, and place the articles to be transported in the load-carrying body frame, The load carrier frame is preferably a frame structure with an opening on the top surface. Even during transportation, the items to be transported in the load carrier will not fall, which ensures the safety of the items to be transported. In the specific transportation process, the trolley can be manually pushed by people, giving the trolley an external thrust to force the trolley to move, and can also provide the trolley with the power to move through the driving mechanism arranged on the carrier frame. , when the two upper wheels 6 rotate on the top surface of the H-shaped steel 12 during rolling, then the four lower wheels 8 cooperate with the H-shaped steel 12 to roll on the lower surface of the top. Similarly, the four side wheels 10 are also matched with the H-shaped steel. The top side of the 12 rolls and walks, so that the whole formed trolley rolls and walks on the H-beam 12, and the items to be transported can be transported from one side of the H-beam 12 to the other side.
