DETAILED DESCRIPTION

[0019] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0020] like Figures 1 to 3A reinforced boom structure shown includes a long axis sleeve 1, with curved arms 2 installed at both ends of the long axis sleeve 1, and a reinforcing arm 3 installed on the long axis sleeve 1 close to the curved arm 2, forming a reinforced area between the curved arm 2 and the reinforcing arm 3. The curved arm 2 and the reinforcing arm 3 are connected by a reinforcing plate 4, thereby connecting the curved arm 2 and the reinforcing arm 3 into an integrated structure, further ensuring the strength between the curved arm 2, the reinforcing arm 2 and the long axis sleeve 1, and the thickness of the curved arm 2 is greater than the thickness of the reinforcing arm 3.

[0021] The reinforcing arm 3 is welded or sleeved on the long shaft sleeve 1. The vertical cross-section of the reinforcing arm 3 is arc-shaped, and the concave surface is set upward. The arc-shaped surface can distribute the force more effectively and improve the stability and bearing capacity of the structure.

[0022] like Figure 1 As shown, the bottom surfaces of the curved arm 2 and the reinforcing arm 3 are both curved surfaces with arc-shaped openings facing upwards, and the curvature of the bottom surfaces of the curved arm 2 and the reinforcing arm 3 are consistent.

[0023] like Figure 3 As shown, the crank arm 2 is divided into a large crank arm 5 and a small crank arm 6 and a connecting block 7. A first mounting hole 8 is opened on the plate surface of the connecting block 7, and the long shaft sleeve 1 is inserted into the first mounting hole 8. The small crank arm 6 is installed on the upper end of the connecting block 7, and the large crank arm 5 is installed on the side wall of the connecting block 7 adjacent to the small crank arm 6. The angle ɑ between the large crank arm 5 and the small crank arm 6 is 85° to 100°. The existence of this angle increases the flexibility of the transport vehicle when transporting goods, making it easier to adapt to goods of different shapes and sizes. The appropriate angle setting helps to improve the maneuverability of the transport vehicle, making the operator more accurate and convenient when transporting goods, enhancing the stability of the transport vehicle when transporting heavy objects, and reducing the shaking of goods during the transportation process; at the same time, it expands the operating range of the transport vehicle, enabling it to reach farther or higher positions for operation; in addition, it reduces the wear of the rocker arm and other components during operation and extends their service life; and reduces the number of adjustments required by the operator during the transportation process, thereby improving operating efficiency;

[0024] And when working on uneven ground, the angle adjustment can help the transporter better adapt to the ground conditions, keep the goods stable, reduce the tilting or sliding of the goods during the transportation process, and improve the safety of the operation.

[0025] The lower end of the small curved arm 6 is an inclined portion 63, and the upper end of the small curved arm 6 is a straight portion 61. A second mounting hole 62 is provided on the upper portion of the straight portion 61. One side surface of the inclined portion 63 is an inclined surface inclined from the inside to the outside, and the side surface is close to the large curved arm 5.

[0026] like Figure 3As shown, the large curved arm 5 is divided into an inclined arc segment 51 and a straight connecting segment 52. The straight connecting segment 52 is arranged parallel to the reinforcing arm 3. The inclined arc segment 51 is inclined from the outside to the inside. The top surface of the inclined arc segment 51 is an inclined surface from the outside to the inside. The inclined surface can increase the stability of the structure; wherein, the bottom surface of the straight connecting segment 52 is an arc-shaped surface.

[0027] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
