[0068] Furthermore, although the terms used in the present invention are selected from well-known and commonly used terms, some terms mentioned in the present specification may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description herein.

[0069] Furthermore, it is required that the present invention be understood not only by the actual terms used but also by the meanings lying behind each term.

[0070] like Figure 2 and Figure 3 As shown, the present invention discloses a quay crane annular main beam, which is preferably an annular closed structure. The annular main beam of the quay crane adopts different structural forms according to different positions. The annular main beam of the quay crane includes two first beams 10 with annular cross-sections, a plurality of beam partitions 20, a plurality of reinforcing ribs 30, and an arc-shaped transition beam 40. The transition beam 40 is installed at both ends of the two first beams 10 to form the main structure of the annular main beam. The cross-sectional shape of the main structure can be trapezoidal, rectangular or semicircular. The beam partitions 20 are arranged in the box body of the first beam 10, for example, they are arranged in the beam box body according to zones. The reinforcing ribs 30 are fixed on the inner wall surface of the first beam 10. Rail support beam assemblies 50 are also provided on both sides of the first beam 10, and trolley tracks 60 are provided on the rail support beam assemblies 50 for trolley transportation.

[0071] Preferably, if Figure 3 As shown, the first beam 10 may include an inner circular web 11, an upper circular flange 12, an outer circular web 13, and a lower circular flange 14, which are welded together to form a large circular main beam with an annular cross-section. The cross-section of the large circular main beam may be trapezoidal, rectangular, or semicircular.

[0072] The reinforcing ribs 30 are preferably flat steel reinforcing ribs, which are fixed to the inner wall surfaces of the inner arc web 11 , the upper annular wing plate 12 , the outer arc web 13 and the lower annular wing plate 14 at intervals.

[0073] Preferably, each track beam assembly 50 includes a track beam panel 51 and a track beam web 52, and one side of the track beam panel 51 is welded to the inner arc web 11 or the outer arc web 13, and the height of the track beam panel 51 is aligned with the height of the adjacent reinforcing rib 30 on the inner side of the first beam 10.

[0074] The lower end of the rail beam web 52 is welded to the outer edge of the lower annular wing plate 14, and the upper end is welded to the rail beam face plate 51. The plate thickness centerline of the rail beam web 52 is aligned with the web centerline.

[0075] In addition, the center position of the trolley is aligned with the center of the web plate 52 of the track beam and is welded to the track beam panel 51. The center position of the trolley track 60 is aligned with the center of the web plate 52 of the track beam and is welded to the track beam panel 51.

[0076] like Figure 5 and Figure 6 As shown, the first beam 10 is located at the upper beam interface D1 on the land side (as shown in FIG. Figure 2 A first reinforcing plate 70 is provided at the center line A2-A2, A3-A3), which is embedded in the inner arc web 11 and the outer arc web 13, and is bent along the edge of the upper circular wing plate 12 and extends vertically upward for aligning with the upper cross beam on the land side.

[0077] Furthermore, a first left bulkhead 15 and a first right bulkhead 16 are provided on the first beam 10. The spacing between the first left bulkhead 15, the first right bulkhead 16, and the first bulkhead 120 corresponds to the width of the landside upper crossbeam. The first left bulkhead 15 and the first right bulkhead 16 are welded to the inner wall surfaces of the inner circular web 11, the upper circular wing 12, the outer circular web 13, and the lower circular wing 14, that is, welded within the housing of the first beam 10, aligned with the transverse bulkheads of the landside upper crossbeam. Reinforcing ribs are placed around the bulkhead openings of the first left bulkhead 15 and the first right bulkhead 16 to prevent deformation under stress.

[0078] like Figure 7 and Figure 8 As shown, on the first beam 10, the rear support pipe interface D2 position (as shown Figure 2At the center line B1-B1, A4-A4), a rib plate 17 is arranged in the middle of the upper cross beam on the land side, and the front and rear ends of the rib plate 17 are fixed to the middle of the upper cross beam on the land side through the first partition member 120 and the second partition member 130. A flat bar is provided in the middle of the first partition member 120 and the second partition member 130, which abuts against the two ends of the rib plate 17 and is welded and fixed. Preferably, reinforcing ribs are arranged around the rib plate 17. In order to facilitate the welding of the rib plate 17, the partitions of the first partition member 120 and the second partition member 130 are not hollowed out in the middle, and small holes are opened on both sides. Reinforcing ribs are also arranged around the second partition member 130.

[0079] like Figure 9 As shown, a second reinforcing plate 18 is installed on the first beam 10 at the seaside upper crossbeam interface D3. This second reinforcing plate 18 is embedded in the inner and outer arcuate webs 11 and 13, and extends vertically upward along the edge of the upper annular wing 12, facilitating alignment with the seaside upper crossbeam. The spacing between the second left and right bulkheads 150 and 160 matches the width of the seaside upper crossbeam. Reinforcing ribs are arranged around the bulkhead openings to prevent deformation under stress.

[0080] like Figures 10 to 12 As shown, the first beam 10 is located at the tie rod interface D4 position (as shown Figure 2 A plate 19 is provided at the center line A6-A6, A7-A7), and a slot is provided in the middle position of the first beam 10, into which the plate 19 is inserted, for example, vertically inserted. The second left partition member 150 and the second right partition member 160 respectively clamp the two ends of the plate 19, so that the two ends of the plate 19 are welded to the second left partition member 150 or the second right partition member 160. The third partition member 140 is divided into two and placed in the middle of 19, clamping the plate 19 from both sides and welded to the plate 19. The upper part of the plate 19 is welded to the third reinforcing plate 200, and the third reinforcing plate 200 is preferably pre-set with ear holes to facilitate the installation of the pull rod for connecting the external joint.

[0081] In addition, reinforcing ribs are arranged around the openings of the second left partition member 120, the second right partition member 130, and the third partition member 140 to prevent the partitions from deforming under stress. The arc sections at both ends of the beam, the reinforcing ribs in the box, the support beam, and the web are all bent according to the arc curvature.

[0082] As described above, the circular main girder of the quayside bridge of the present invention consists of two girders with an annular cross-section. Arc-shaped transition beams connect the two girders at each end of the quayside bridge main girder, forming a circular girder. Girder partitions are spaced regularly within the girder. Flat steel bars pass through the partitions and are positioned on the upper and lower flanges and webs of the circular girder. Track-bearing beams are designed at the lower flanges of both sides of the circular girder to support the trolley tracks.

[0083] After loading containers on one girder, the trolley travels through the seaside arc transition area to the other girder for unloading, then continues on to the landside arc transition area before returning to its original position, thus forming a cyclic operation. By increasing the number of trolleys on the quayside crane's circular main girder, the loading efficiency of the quayside crane can be effectively improved.

[0084] In summary, the circular main beam of the quay crane of the present invention replaces the existing single-track structure with a "circular runway." During use, it can effectively increase the number of trolleys that can operate. The circular main beam of the quay crane enables continuous, cyclic operation, thereby improving the loading efficiency of the quay crane.
