Abstract
Description
Technical Field
[0001] This invention relates to the field of test bench technology, specifically an integrated test bench for a marine boom crane. Background Technology
[0002] Marine boom cranes are core equipment for loading and unloading cargo and offshore operations. Their performance (such as anti-sway and heavy load stability) directly affects the efficiency and safety of ship operations and must be rigorously tested and verified (in accordance with the standards of international / domestic classification societies such as IMO and CCS).
[0003] Currently, existing technologies require specialized horizontal and inclined test benches to meet factory testing requirements. These two test benches occupy work space and are costly. During the testing of two different working conditions, it is time-consuming and labor-intensive to remove the crane from one test bench and install it on the other. Furthermore, the dynamic working conditions pose a high risk and are prone to equipment damage or safety accidents.
[0004] Therefore, an integrated test bench for marine boom cranes was designed based on the above-mentioned technical problems. Summary of the Invention
[0005] To overcome the shortcomings of existing technologies and solve the problems mentioned in the background art, this invention proposes an integrated test bench for marine boom cranes.
[0006] The technical solution adopted by the present invention to solve its technical problem is: an integrated test bench for a marine boom crane, including a mounting base, on which a tilt adjustment frame, a mounting plate and a pitch adjustment frame are arranged sequentially from bottom to top. A connecting seat is provided at the top of the pitch adjustment frame. The tilt adjustment frame is hinged to the mounting base. A fixing component is provided between the tilt adjustment frame and the mounting base. The pitch adjustment frame is hinged to the mounting plate. A fixing device is provided between the pitch adjustment frame and the mounting plate. The hinge direction of the tilt adjustment frame and the mounting base is perpendicular to the hinge direction of the pitch adjustment frame and the mounting plate.
[0007] Furthermore, two mounting blocks are symmetrically arranged on the mounting base, and the tilt adjustment frame includes two connecting plates corresponding to the mounting blocks. The mounting blocks and connecting plates are connected by a central shaft, which is located at the center of the mounting base.
[0008] Furthermore, the fixing component includes two fixing plates arranged perpendicular to the mounting block. Each fixing plate is provided with a limiting hole. The bottom of the mounting plate is provided with an adjusting plate assembly corresponding to the position of the fixing plate. One end of the adjusting plate assembly is provided with two mounting holes and the other end is provided with one mounting hole. The two mounting holes are arranged correspondingly from top to bottom. The limiting hole and the mounting hole can be connected and fixed by fixing bolts.
[0009] Furthermore, two connecting blocks are symmetrically arranged above the mounting plate, and the tilt adjustment frame includes two connecting plates corresponding to the connecting blocks. The connecting blocks and connecting plates are connected by a central shaft. The central shaft is located at the center of the mounting plate, and the central shaft and the central shaft are vertically arranged.
[0010] Furthermore, the fixing device includes two fixing plates arranged perpendicularly to the connecting block at the bottom of the connecting seat. One fixing plate has two adjustment holes arranged horizontally, and the other fixing plate has one adjustment hole. The mounting plate has an adjustment plate assembly corresponding to the position of the fixing plates. One end of the adjustment plate assembly has two mounting holes and the other end has one mounting hole. One end of the two mounting holes corresponds to the fixing plate with the two adjustment holes. The two mounting holes are inclined downwards. The adjustment holes and the mounting holes can be connected and fixed by fixing bolts.
[0011] Furthermore, the longitudinal tilt adjustment bracket adjusting connecting seat is tilted longitudinally by 2°, and the lateral tilt adjustment bracket adjusting connecting seat is tilted laterally by 5°.
[0012] Working Principle: Since marine boom cranes need to simulate the horizontal, heel, and trim conditions of a ship, and to meet these tests, specialized horizontal and tilting platforms are required. Therefore, this invention was designed to address these technical problems. This invention uses purely mechanical settings to simulate horizontal and lateral tilt (5°) and longitudinal tilt (2°) conditions on the crane. Specifically, when testing the horizontal angle, a fixing bolt is inserted into an adjustment hole on the fixed plate and fixed to the adjustment assembly. Simultaneously, a mounting hole on the adjustment plate assembly is inserted into a corresponding limit hole and fixed to the adjustment assembly. When a 2° longitudinal tilt is required, remove the fixing bolts at the tilt adjustment bracket, align the end of the fixing plate with the two adjustment holes with the corresponding two mounting holes, and insert the fixing bolts to achieve a 2° longitudinal adjustment. When a 5° lateral adjustment is required, remove the aforementioned bolts and the fixing bolts at the lateral tilt adjustment bracket, insert the fixing bolts at the horizontal tilt adjustment point, and then insert the fixing bolts at one end of the adjustment plate assembly with two mounting holes and the other end with one mounting hole. Depending on whether an upward or downward tilt is required, insert the fixing bolts into the positions of the upper and lower holes to complete the 5° lateral adjustment.
[0013] Furthermore, the adjusting plate assembly includes two adjusting plates, and the fixing plate is disposed between the two adjusting plates. The second adjusting plate assembly includes two second adjusting plates, and the second fixing plate is disposed between the two second adjusting plates, which can make the fixing more stable.
[0014] Furthermore, the lower surface of the connecting plate is arc-shaped, the upper surface of the connecting block is arc-shaped, and two support plates are provided on the outward side of the connecting plate. The two support plates are symmetrically arranged on both sides of the central axis. The connecting block is provided with two second support plates, which are symmetrically arranged on both sides of the second central axis, thereby enhancing the impact resistance and extending the service life.
[0015] Furthermore, the mounting base and connecting seat are cylindrical structures, and the mounting plate is a circular plate structure, which makes the footprint smaller and the adjustment direction smoother.
[0016] The advantages of this invention are: 1. The present invention enables cranes that need to simulate the horizontal and inclined conditions of ships to complete the task with a single device, eliminating the need for multiple devices, thus shortening the test cycle, reducing user costs, simplifying the test process, and reducing time consumption.
[0017] 2. The adjusting plate assembly of the present invention includes two adjusting plates, and the fixing plate is disposed between the two adjusting plates. The second adjusting plate assembly includes two second adjusting plates, and the second fixing plate is disposed between the two second adjusting plates, which can make the fixing more stable.
[0018] 3. The lower surface of the connecting plate of the present invention is arc-shaped, the upper surface of the connecting block is arc-shaped, and two support plates are provided on the outward side of the connecting plate. The two support plates are symmetrically arranged on both sides of the central axis. The connecting block is provided with two second support plates, which are symmetrically arranged on both sides of the second central axis, thereby making the impact resistance stronger and the service life longer.
