Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0022] like Figure 1-5As shown, this utility model provides a segmented reinforcement structure for a crane boom, including a bottom support frame 1, side reinforcement frames 2, support members 3, top inclined frame 4, connecting arm 5, longitudinal reinforcement rods 6, diagonal reinforcement rods 7, and a first reinforcement plate 8. Side reinforcement frames 2 are welded and fixed on both sides of the bottom support frame 1. The top inclined frame 4 is supported and installed on the bottom support frame 1. The bottom support frame 1, the top inclined frame 4, and the connecting arm 5 are connected to form a triangular structure. Several longitudinal reinforcement rods 6 are vertically installed between the bottom support frame 1 and the top inclined frame 4. Diagonal reinforcement rods 7 are installed obliquely between the longitudinal reinforcement rods 6. The bottom end of the longitudinal reinforcement rod 6 is welded and fixed by the first reinforcement plate 8, and the bottom surface of the first reinforcement plate 8 is welded to the bottom support frame 1 and the side reinforcement frames 2.
[0023] The segmented reinforcement structure of the crane boom in this utility model forms a stable truss structure through a triangular main frame composed of a bottom support frame 1, a top inclined frame 4, and a connecting arm 5. Combined with a grid support system composed of longitudinal reinforcing rods 6 and diagonal reinforcing rods 7, it can improve the overall performance of the boom in terms of bending resistance, torsion resistance, and compressive resistance.
[0024] According to some embodiments of this utility model, optionally, a second reinforcing plate 9 is installed at the bottom end of the connecting arm 5, and one end of the side reinforcing frame 2 is welded to the second reinforcing plate 9. The welded connection between the second reinforcing plate 9 and the side reinforcing frame 2 forms a high-strength node, which effectively improves the load transfer efficiency between the connecting arm 5 and the bottom support frame 1 and the side reinforcing frame 2, and reduces stress concentration.
[0025] According to some embodiments of this utility model, optionally, the bottom support frame 1 and the side reinforcement frame 2 are made of high-strength steel. High-strength steel has excellent yield strength and tensile properties, which improves the load-bearing capacity of the bottom support frame 1 and the side reinforcement frame 2.
[0026] According to some embodiments of this utility model, optionally, four longitudinal reinforcing bars 6 are provided, and the length of each longitudinal reinforcing bar 6 is different. The longitudinal reinforcing bars 6 of different lengths form a gradient support, so that the load is transmitted more evenly along the length of the boom, avoiding local stress concentration and improving the bending and compressive stability of the overall structure.
[0027] According to some embodiments of this utility model, optionally, the bottom support frame 1, the side reinforcing frame 2, the supporting member 3, and the top inclined frame 4 are hollow structures. The hollow structure can reduce the self-weight of the crane boom and lower the overall mass of the crane.
[0028] According to some embodiments of this utility model, optionally, at least two diagonal reinforcing rods 7 are provided.
