Detailed Implementation
[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0016] As shown in Figures 1-4, a gantry crane-type ship unloading anti-collapse device in this embodiment includes a horizontally arranged main support rod 1. Side mounting plates 2 are respectively installed at both ends of the main support rod 1, and the side mounting plates 2 are fixed to the bottom beam of the gantry crane-type ship unloader. Sliding grooves are respectively opened on both sides of the main support rod 1, and sliding plates 3 are respectively inserted into the grooves. The two sliding plates 3 are fixedly connected by sliding connecting plates. A main upright rod 5 is provided above the main support rod 1, and the main upright rod 5 is fixed between the sliding plates 3. When the main upright rod moves, it drives the sliding plates to move along the grooves. A vertically arranged lifting rod 6 passes through the top of the main upright rod 5, and a top mounting plate 7 is fixed to the top of the lifting rod 6. The lifting rod 6 can move vertically within the main upright rod 5, driving the top mounting plate 7 to move synchronously. A through groove is opened on one side of the main upright rod 5, and two vertically spaced connecting seats 8 pass through the through groove. One side of the connecting seat 8 is fixed to the lifting rod 6, and the other side of the connecting seat 8 is fixed to an extension mounting plate 9. An end mounting plate 11 is provided on the outer side of the extension mounting plate 9, and the two are arranged parallel to each other. The extension mounting plate 9 and the end mounting plate 11 are fixedly connected by two parallel extension connecting plates 10. The end mounting plate 11 and the top mounting plate 7 are installed on the top beam of the gantry crane ship unloader, and support the gantry crane ship unloader through the side mounting plate 2, the top mounting plate 7, and the end mounting plate 11, forming an anti-collapse support structure. Sliding mounting seats 13 are also respectively installed in the chute, and the sliding mounting seats 13 and the end mounting plates 11 are respectively located on both sides of the main support rod 5. A horizontally arranged first hydraulic rod 4 is provided above the main support rod 1. The fixed end of the first hydraulic rod 4 is fixed to the sliding connecting plate, and the extended end of the first hydraulic rod 4 is fixedly connected to the side mounting plate 2 near the sliding mounting seat 13. Bottom bearing seats 14 are respectively provided on the top of the sliding mounting seats 13, and end bearing seats 12 are symmetrically provided on the side of the end mounting plate 11, and the end bearing seats 12 are located on the outside of the extension connecting plate 10. An inclined second hydraulic rod 15 is provided between the bottom bearing seat 14 and the end bearing seat 12 on the same side. When the gantry crane unloader moves up and down, the lifting rod moves vertically within the main support column, and the second hydraulic rod extends and retracts, thus satisfying the lifting adjustment of the gantry crane unloader. When the gantry crane unloader moves forward and backward, the first and second hydraulic rods extend and retract, causing the sliding mounting seat and sliding plate to move forward and backward on the main support column, thus satisfying the forward and backward adjustment of the gantry crane unloader. Through the cooperation of the lifting rod, sliding plate, sliding mounting seat, first hydraulic rod, and second hydraulic rod, the gantry crane unloader can be adjusted simultaneously during lifting and forward / backward movement, thus satisfying the lifting and forward / backward adjustment of the gantry crane unloader. This device can adjust simultaneously with the adjustment of the gantry crane unloader, always providing support and preventing collapse of the gantry crane unloader.
[0017] The aforementioned main support rods and main uprights are arranged vertically, and the main uprights and limb support rods serve as anti-collapse support components.
[0018] This application is easy to operate, requires no repeated disassembly and installation, and can be adjusted simultaneously with the gantry crane ship unloader, which not only saves time and effort but also improves work efficiency.
[0019] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
