Description

Technical Field

[0001] This utility model relates to the field of marine vessel load handling equipment, and in particular to the field of load handling bracket technology on ships, specifically to an airbag-type bidirectional adjustable anti-collision bracket system. Background Technology

[0002] The anti-collision bracket system (hereinafter referred to as the bracket) is mainly used to protect the load during the roll-on / roll-off loading, sea loading and unloading, and anchoring dismantling process, to prevent the load from colliding with the dock walls on both sides, the bracket and other facilities on the deck and causing damage, to guide the load to be centered and to lift and lower the load. The equipment must meet the relevant standards and specifications for marine products and be able to ensure the normal completion of the above-mentioned test work under sea state 3.

[0003] Existing technology typically involves directly fixing the bracket to the ship's deck, allowing the load to be rolled onto the ship via the bracket. A drawback is that the bracket is often in a fixed position. When the load's shape changes significantly, requiring adjustment of the bracket's left-right or up-down position, this is often difficult and necessitates disassembly and reinstallation, undoubtedly slowing down the work process. Utility Model Content

The movable end of the transverse hydraulic cylinder is hinged to the side wall of the intermediate frame, and the housing of the transverse hydraulic cylinder is hinged to the side of the square steel.

[0015] Furthermore, the bracket includes a horizontal section and a vertical section connected to the left and right ends of the horizontal section. The airbag is located on the horizontal section of the bracket, and the left and right ends of the airbag pass through the vertical section of the bracket and are fixedly connected to the docking support.

[0016] Furthermore, the bracket has a semi-arc structure, and a groove is provided on the arc surface of the bracket. The airbag is located in the groove, and the left and right ends of the airbag are respectively fixedly connected to the docking support.

[0031] Example 1

[0032] To address the problems in the background technology, this embodiment discloses an airbag-type bidirectional adjustable anti-collision bracket system, such as... Figure 1-2As shown, the system includes a bracket unit, which mainly comprises a docking support 1, a bracket component 2, an airbag 3, an intermediate frame 4, a base frame 5, a vertical lifting device, and a horizontal lifting device. The docking support 1 is horizontally distributed on both sides and is constructed of welded steel with an anti-corrosion coating. Steel columns are also welded to the left and right sides of the top surface of the docking support 1; these two steel columns are used for the subsequent installation of the bracket component 2.

[0033] The bracket component 2 is made of metal sheet and includes a horizontal section in the middle and vertical sections connecting to the left and right ends of the horizontal section. An airbag 3 is located on the horizontal section of the bracket component 2. The left and right ends of the airbag 3 pass through the vertical sections of the bracket component 2 and are fixedly connected to the docking support 1. The top surface of the airbag 3 is used to contact the load. The surface of the bracket component 2 is provided with a 30mm thick rubber shock-absorbing pad 6. The surface of the rubber shock-absorbing pad 6 is densely covered with multiple circular protrusions, which increases friction and facilitates drainage. It has anti-collision and anti-slip capabilities, used to buffer the impact load and prevent slippage when seated.

[0034] Two sets of intermediate frames 4 are located on the left and right sides of the bottom of the docking support, respectively. A column 13 is fixed to the top surface of the intermediate frame 4. The bottom of the docking support 1 has a cavity that slides up and down in conjunction with the column 13. A vertical lifting device is selected using a vertical hydraulic cylinder 7. The movable end of the vertical hydraulic cylinder 7 faces downwards and is hinged to the intermediate frame. The housing of the vertical hydraulic cylinder 7 is hinged to the top side of the docking support 1. The vertical hydraulic cylinder 7 can control the stable lifting and lowering of the docking support 1 relative to the intermediate frame 4.

[0035] The base frame 5 consists of two sets, located below and slidably connected to the intermediate frame 4. Specifically, the base frame 5 includes transversely distributed square steel bars 9, with anti-slip bases 10 fixed on the left and right sides of the bottom of each square steel bar 9. These anti-slip bases are used for securing the frame to the ship's deck. The intermediate frame 4 is fitted onto the outside of the square steel bars and can slide relative to them. The transverse lifting device uses a transverse hydraulic cylinder 8. The movable end of the transverse hydraulic cylinder 8 is hinged to the side wall of the intermediate frame 4, and the housing of the transverse hydraulic cylinder 8 is hinged to the side of the square steel bars. Through the transverse hydraulic cylinder, the intermediate frame 4 can move laterally back and forth relative to the base frame 5.

[0036] Taking the placement of loads during semi-submersible vessel navigation as an example, multiple airbag-type bidirectional adjustable anti-collision bracket systems as described in this embodiment are fixed on the deck of the semi-submersible vessel. Each airbag-type bidirectional adjustable anti-collision bracket system includes a bracket unit. By adjusting the height and lateral position of the bracket component 2 and the airbag through the vertical hydraulic cylinder 7 and the lateral hydraulic cylinder 8, the load can smoothly contact the airbag. The system assists in loading and unloading loads and in segmentation operations. The overall system has a load capacity of 1500t, and the synchronous control accuracy during the overall lifting and lowering of the bracket system is ≤±2mm / m, ensuring that loads of different sizes and shapes do not tip over during segmentation operations.

[0037] With the above solution, the airbag is set on the bracket 2 for load contact, avoiding damage to the load from collision with other structures of the ship. The vertical lifting device and the horizontal lifting device can adjust the overall height and lateral position of the airbag and the bracket 2 to meet the requirements of load roll-on and roll-off loading, thus improving work efficiency.

[0038] Example 2

[0039] This embodiment provides an airbag-type bidirectional adjustable anti-collision bracket system, which differs from the solution in Embodiment 1 in that... Figure 3 As shown, the bracket 2 has a semi-circular structure with grooves machined on its curved surface. The airbag is located within the grooves, and its left and right ends are fixedly connected to the docking support 1, respectively. The bracket 2 is designed with a semi-circular structure to accommodate different ship hulls; for example, a curved shape is suitable for the bow and stern, while the solution in Embodiment 1 is suitable for the midsection of the ship.

[0040] Example 3

[0041] Because the load is relatively large, in order to prevent the bracket from tipping over, such as Figure 4 As shown, this embodiment provides an airbag-type bidirectional adjustable anti-collision bracket system. The bracket units consist of two sets. Four docking flanges 11 are installed on the front or rear side of the docking support 1, symmetrically distributed in pairs. Adjacent bracket units are connected as a whole by connecting steel pipes 12 and the docking flanges. When the vertical hydraulic cylinder is raised, a stable structure is formed, ensuring that the load will not tip over during segmented operation.
