Description

Technical Field

[0001] This utility model relates to a guide roller base structure that also serves as a stop, belonging to the technical field of marine elevator body structure design. Background Technology

[0002] With increasingly demanding requirements for vehicle and cargo transfer on ships, there is an urgent need to improve the design load-bearing capacity of marine elevators and increase platform size. However, this also brings problems such as the large platforms being prone to tilting under eccentric loading and the difficulty in controlling the design weight of the elevator platform itself. To ensure the normal operation of such large elevators during ship navigation and to prevent tilting or jamming under eccentric loading, guide rollers are generally used to constrain them, ensuring that the elevator moves vertically along a pre-set track. In addition, to ensure that the elevator can smoothly reach the stopping position during vertical transfer, vertical stops are generally required to ensure proper alignment between the elevator body deck and the ship's stopping deck. Typically, separate structural bases are required for these two types of devices, resulting in complex interfaces, system redundancy, and difficulties in arranging the already limited installation space, as well as wasting the weight resources of the elevator itself. Utility Model Content

[0003] The technical problem to be solved by this utility model is the complex interface of the guide rollers and stop devices of large-size elevators, and the waste of weight resources in the base design.

[0004] To solve the above problems, this utility model provides a guide roller base structure that also serves as a stop, characterized in that it includes a pair of base panels connected to the elevator body and arranged vertically, with a base elbow plate and a base web plate perpendicular to each other between the two base panels, and the mounting seat of the guide roller is connected to the base web plate.

[0005] Preferably, the base panel is trapezoidal, with its larger base edge connected to the elevator body.

[0006] Preferably, the outer edge of the base panel is provided with a base edge plate.

[0007] Preferably, a stop block is provided at the top of the upper base panel.

[0008] More preferably, the stop block contacts the hull end stop during operation.

[0009] More preferably, the stop block is made of E36 steel.

[0010] More preferably, the stop block has dimensions of 60mm×350mm×280mm.

[0011] Preferably, there are three base elbow plates. The base elbow plates on both sides are symmetrical about the base web, and the middle base elbow plate is located on the other side of the base web opposite to the mounting seat of the guide roller.

[0012] More preferably, the base panel is an isosceles trapezoid, and the base web is located on the center line of the isosceles trapezoid.

[0013] Preferably, the web of the base is provided with web reinforcing ribs.

[0014] This invention designs a guide roller base structure that also functions as a stop, combining the conventional guide roller base and stop block base into one, saving interface space and elevator body material weight. Through a rationally designed base structure, it can simultaneously meet the design load requirements of both the longitudinal guide rollers and the vertical stop block, achieving integrated design. This structure has been applied on actual ships and is performing well.

[0015] This invention can simultaneously meet the design load requirements of the longitudinal guide roller and the vertical stop block, and it is well matched with the hull end stop and guide rail, greatly saving installation and debugging space. Attached Figure Description

[0023] To make this utility model more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0024] Example

[0025] like Figure 1-3 As shown, this utility model provides a guide roller base structure that also serves as a stop. It includes a pair of base panels 2 connected to the elevator body 8 and arranged vertically. A base elbow plate 4 and a base web plate 5 are provided between the two base panels 2 and are perpendicular to each other. The mounting seat of the guide roller 7 is connected to the base web plate 5.

[0026] like Figure 1 As shown, the base panel 2 has two pieces that are suspended above the elevator body, serving as the mounting surface for the stop blocks and bearing the longitudinal load from the guide rollers.

[0027] like Figure 1 , 2 As shown, the base panel 2 is an isosceles trapezoid, with its larger base edge connected to the elevator body 8. The base web 5 is located on the center line of this isosceles trapezoid. The base panel 2 is trapezoidal. A base edge plate 3 is provided on the outer edge of the base panel 2. A stop block 1 is provided at the top of the upper base panel 2, which can contact the hull end stop during operation and bear load. The stop block is located above the base web and the elbow plate, effectively transferring the load to the structural base.

[0028] There are three base elbow plates 4, arranged at the center of the guide roller mounting surface and on both sides of the mounting bolts, effectively transferring the guide roller load to the base web and base panel. The two base elbow plates 4 on both sides are symmetrical about the base web 5, and the middle base elbow plate 4 is located on the base web 5 on the other side opposite to the mounting seat of the guide roller 7. One base web 5 is provided, suspended above the elevator body, serving as the mounting surface for the guide rollers and bearing the longitudinal load brought by the guide rollers.

[0029] like Figure 3 As shown, the base web 5 is provided with web reinforcing ribs 10.

[0030] This utility model is arranged on one side of the installation surface of a large elevator. Each elevator is equipped with two guide roller base structures that also serve as stops. Figure 4 As shown in Figure B, the entire base is suspended above the elevator body, bearing the vertical load of the stop block and the longitudinal load of the guide roller, and is compatible with all interfaces, combining the two bases of the conventional solution into one.

[0031] like Figure 5-6As shown in the simulation calculations, the maximum combined stress of the base structure of this invention under the design load of the guide rollers and stop blocks is 101 MPa, and the maximum deformation is 0.9 mm, indicating good structural strength and stiffness performance. Furthermore, compared to the conventional approach of using two separate bases—one for the stop blocks and one for the guide rollers—the design weight of the elevator body is reduced by approximately 350 kg. Actual shipboard testing has confirmed its good performance.
