[0021] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0023] Reference Figures 2-5 This embodiment provides a gantry bridge 1 with a triangular rib structure. The gantry bridge 1 can be used to support a machine head (not shown). In this embodiment, the gantry bridge 1 is provided with an upper guide rail surface 101 and a side guide rail surface 102. The machine head can be displaced and installed on the gantry bridge 1 through the upper guide rail surface 101 and the side guide rail surface 102.
[0024] The gantry bridge 1 includes a gantry bridge body 10 extending laterally, and two support columns 20 supporting the gantry bridge body 10 from below.
[0025] The main body 10 of the gantry bridge includes a first horizontal plate 15, a second horizontal plate 14, a first vertical plate 13, a second vertical plate 16, a first inclined plate 11, and a second inclined plate 12, all extending laterally.
[0026] The first horizontal plate 15, the first inclined plate 11, and the second inclined plate 12 form a triangular rib structure, such as Figure 5 As shown. The first horizontal plate 15 forms the base plate of the triangular rib structure, and the first inclined plate 11 and the second inclined plate 12 form the two side plates of the triangular rib structure. The internal ribs are triangular in structure, which utilizes the principle of stability of triangles to provide stability, firmness, and pressure resistance, thereby improving the rigidity of the gantry bridge body 10 and reducing deformation.
[0027] The first vertical plate 13 extends vertically upward from the first horizontal plate 15 to the apex of the triangular rib structure, so that the first vertical plate 13, the first inclined plate 11, and the second inclined plate 12 converge at the same apex. The upper guide rail surface 101 is located at the apex of the triangular rib structure, so that the triangular rib structure provides stable support to the upper guide rail surface 101, reducing the deformation of the gantry bridge body 10 and further improving rigidity; at the same time, it can also reduce the forward tilt angle of the machine head relative to the crossbeam when it is on the gantry bridge 1, and reduce the difference in the forward tilt of the machine head at different positions on the gantry bridge 1.
[0028] The second horizontal plate 14 is connected to the vertex of the triangular rib structure on one side and to the upper end of the second vertical plate 16 on the other side. The lower end of the second vertical plate 16 is connected to the first horizontal plate 15. Thus, the first horizontal plate 15, the second horizontal plate 14, the first vertical plate 13, and the second vertical plate 16 form a rectangular frame structure. The first inclined plate 11 forms one of the diagonals of the rectangular frame structure. The upper guide rail surface 101 is provided on the second horizontal plate 14, thereby further increasing the rigidity of the portal bridge body 10 and reducing the amount of deformation.
[0029] Furthermore, the main body 10 of the gantry bridge also includes a third horizontal plate 18 and a third vertical plate 19. The third horizontal plate 18 extends outward from the middle of the first vertical plate 13 in a direction perpendicular to the first vertical plate 13 to the outside of the second inclined plate 12. The end of the third horizontal plate 18 outside the second inclined plate 12 is connected to the upper end of the third vertical plate 19. The lower end of the third vertical plate 19 is connected to the first horizontal plate 15. The side guide rail surface 102 is provided on the side of the third vertical plate 19. The second inclined plate 12 is close to the side guide rail surface 102, thereby improving the rigidity of the side guide rail surface 102.
[0030] The gantry bridge body 10 has outer side plates 17 at both ends, which close the two ends of the gantry bridge body 10, thereby improving the strength and rigidity of the gantry bridge body 10 and enhancing its aesthetics.
[0031] Process holes are provided on the first horizontal plate 15, the second horizontal plate 14, the first vertical plate 13, the second vertical plate 16, the first inclined plate 11, and the second inclined plate 12, such as... Figure 4 As shown in reference numerals 151, 141, 131, 161, 111 and 121, the setting of process holes has little effect on the structural strength and stiffness of the portal bridge 1, which can be almost ignored, and reduces the overall weight of the portal bridge 1, saving materials.
[0032] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
