Description

Technical Field

[0001] This application relates to the field of ship pipe testing equipment technology, and more specifically, to a ship pipe strength testing device. Background Technology

[0002] Rowing is a popular water sport. To ensure the balance of the rowing boat on the water, a small boat is usually attached to one side of the main boat and connected to it via a hull tube. Due to the complex and changeable marine environment, with frequent large waves, the hull tube needs to have high strength to ensure the rowing boat's ability to withstand wind and waves and the safety of the operators. Therefore, its strength testing is crucial.

[0003] Currently, the strength testing of ship tubing largely relies on general-purpose tensile testing equipment, lacking dedicated devices for this purpose. In practical use, these general-purpose tensile testing devices present several problems: Firstly, due to the different curvatures of the main body and the hull end of the tubing, general-purpose equipment cannot perform targeted testing on these different parts, making it difficult to accurately simulate the tensile forces experienced by the tubing at both ends during actual use. This results in significant discrepancies between the test results and the actual strength observed in use. Secondly, general-purpose equipment often relies on hydraulic or electric structures to apply tensile force, leading to complex structures, high manufacturing costs, and difficult maintenance, hindering its widespread adoption.

[0020] The present application will now describe a ship pipe strength testing device provided in the embodiments of this application.

[0021] Please see Figure 1 and Figure 2The vessel tube strength testing device includes a workbench 1, which is a frame structure. A mounting shaft 2 is located on the front of the workbench 1, and a handle 3 is rotatably connected to the mounting shaft 2. A pull rope is connected to the front end of the handle 3, and a load block 4 placed on the ground is connected to the pull rope. A guide assembly 5 is located on the front of the workbench 1, and a sleeve 6 is connected to the free end of the pull rope via the guide assembly 5. The sleeve 6 engages with the body end of the vessel tube 7. Specifically, when the operator presses the handle 3, the handle 3 rotates around the mounting shaft 2, and the front end of the handle 3 moves upward, pulling the load block 4 off the ground via the pull rope. The pull rope and the guide assembly 5 work together to convert the weight of the load block 4 into a pulling force on the sleeve 6 and the vessel tube 7. A fixing assembly 8 for fixing the vessel tube 7 is located on the rear of the workbench 1, and a gap is provided on the front of the workbench 1 corresponding to the fixing assembly 8 to engage with the small boat end of the vessel tube 7. Because both ends of the tube 7 have a certain curvature, its installation position varies depending on the testing location. When testing the strength of the small boat end of the tube 7, the fixing component 8 fixes the small boat end of the tube 7, and the main body end of the tube 7 is placed upwards and connected to the sleeve handle 6. When testing the strength of the main body end of the tube 7, the fixing component 8 fixes the main body end of the tube 7, and the small boat end of the tube 7 is placed in the gap in front of the workbench 1. The overall structure of the device is simple, with few parts, low manufacturing cost, and is easy to produce and apply on a large scale.

[0022] Specifically, when testing the strength of the dinghy end of the boat tube 7, the worker secures the dinghy end of the boat tube 7 using the fixing component 8, and places the sleeve 6 on the body end of the boat tube 7 to ensure the boat tube 7 is stable and does not wobble, thus completing the installation of the boat tube 7. Then, the worker presses down on the handle 3, causing the front end of the handle 3 to move upward, pulling the rope to lift the load block 4 off the ground. The pulling force is transmitted through the guide component 5, applying a pulling force equal to the weight of the load block 4 to the body end of the boat tube 7. At this point, the worker observes whether the boat tube 7 breaks, thus determining whether the strength of the dinghy end of the boat tube 7 is qualified. When testing the strength of the body end of the boat tube 7, the worker pre-suspends a load block 4 of a certain weight on the dinghy end of the qualified boat tube 7, marking the position of the dinghy end of the boat tube 7 on the workbench 1. During testing, the worker secures the body end of the boat tube 7 using the fixing component 8, then places the dinghy end of the boat tube 7 into the gap corresponding to the fixing component 8 on the front side of the workbench 1, completing the installation of the boat tube 7. The worker then presses down on the dinghy end of the boat tube 7 by hand. At this point, observe the small boat end of the boat tube 7. Without breaking the boat tube 7, observe whether the downward pressing distance of the small boat end reaches the pre-marked position. This determines whether the strength of the main body end of the boat tube 7 is qualified. This device uses both handle 3 pressing and manual pressing methods to test the strength of the small boat end and the main body end of the boat tube 7, respectively. No additional equipment is required, saving equipment costs. The testing operation is convenient, the process is simple and clear, and the efficiency of testing the strength of the boat tube 7 is improved. Based on the testing requirements of different parts of the boat tube 7, the load block 4 and manual pressing can accurately simulate the stress state of the boat tube 7 in actual use, improving the accuracy of the test results.

[0023] Furthermore, the fixing component 8 includes a first fixing device 801 and a second fixing device 802 arranged side by side on the rear side of the workbench 1. The first fixing device 801 engages with the dinghy end of the boat tube 7, and the second fixing device 802 engages with the body end of the boat tube 7. The second fixing device 802 corresponds to the gap on the front side of the workbench 1. Specifically, when testing the strength of the dinghy end of the boat tube 7, the dinghy end of the boat tube 7 is connected to the first fixing device 801, which firmly fixes the dinghy end of the boat tube 7 to the workbench 1, preventing the boat tube 7 from shifting or shaking during the testing process. When testing the strength of the body end of the boat tube 7, the body end of the boat tube 7 is connected to the second fixing device 802, which ensures that the position of the body end of the boat tube 7 remains fixed when the operator manually presses the dinghy end of the boat tube 7.

[0024] Furthermore, the guide assembly 5 includes a first pulley 501 positioned below the mounting shaft 2, a second pulley 502 positioned above the mounting shaft 2, and a third pulley 503. The load block 4 is located below the guide assembly 5, and a pull rope sequentially connects the first pulley 501, the second pulley 502, the load block 4, and the third pulley 503. Specifically, the first pulley 501 and the second pulley 502 are set at different heights. This height difference ensures that the pull rope remains taut during the transmission of tension, guaranteeing that the load block 4 can rise stably under the traction of the pull rope. After the pull rope pulls the load block 4 off the ground, the third pulley 503 guides the direction of the pull rope, allowing the weight of the load block 4 to act on the boat tube 7 through the handle 6. This ensures that the boat tube 7 is under stable force and its direction is controllable during the testing process, preventing the pull rope from swaying and affecting the transmission of tension and the testing results, thus improving the accuracy of the testing results.

[0025] Furthermore, the first pulley 501 and the second pulley 502 are arranged parallel to the front end face of the workbench 1, while the third pulley 503 is arranged perpendicular to the front end face of the workbench 1. The third pulley 503 guides the tension transmitted through the first pulley 501 and the second pulley 502 to the end of the boat tube 7. The vertical arrangement reduces wear between the pull rope and the third pulley 503, allowing the pull rope to connect to the boat tube 7 at a suitable angle.

[0026] Furthermore, the workbench 1 surface is provided with a vertically upward limiting bracket 9, and the limiting bracket 9 has a gap corresponding to the first fixing device 801 to mate with the body end of the boat tube 7. When the first fixing device 801 fixes the small boat end of the boat tube 7, the body end of the boat tube 7 is positioned upward and passes through the gap of the limiting bracket 9; the limiting bracket 9 prevents the body end of the boat tube 7 from swaying left and right or shifting laterally, ensuring that the boat tube 7 always maintains the correct position during the inspection process, reducing the risk of the boat tube 7 accidentally swaying or falling off.

[0027] Specifically, both the first retainer 801 and the second retainer 802 are cylindrical structures with smooth inner walls, and one end near the rear side of the worktable 1 is inclined downwards. The smooth inner wall of the cylindrical structure facilitates the quick insertion and removal of the boat tube 7, reducing the installation difficulty of the boat tube 7. Considering the angle of the boat tube 7 itself, the first retainer 801 and the second retainer 802 are inclined downwards, conforming to the tilt direction of the boat tube 7, making it easy for the other end of the boat tube 7 to be placed into the gap of the limiting bracket 9 or the front side of the worktable 1.

[0028] In this embodiment, the workbench 1 includes two front columns and two rear columns arranged front to back. The front columns are connected by at least one front beam, and the rear columns are connected by at least one rear beam. The front columns and their corresponding rear columns are connected by at least one crossbeam. The connection of the front columns, rear columns, crossbeams, front beams, and rear beams constitutes a frame structure, which is structurally stable and provides a spacious operating space, facilitating the installation and inspection of the ship pipe 7 by the staff.

[0029] In this embodiment, support rods 10 are symmetrically provided at the top of the two front columns, and a gap is provided between the support rods 10 to mate with the small boat end of the boat tube 7. Specifically, when testing the strength of the main body end of the boat tube 7, the small boat end of the boat tube 7 can be placed in the gap between the two support rods 10. The staff can mark the support rods 10 in advance, which simplifies the judgment process. The support rods 10 are used to assist in positioning, making the test results more intuitive and clear, and making it easier for the staff to observe and judge after manually pressing. The staff can quickly draw the test conclusion simply by observing the position of the small boat end of the boat tube 7 after being pressed and comparing it with the mark.

[0030] In this embodiment, the pull rope is made of high-horsepower wire; one end of the pull rope is connected to the handle 3 via a ring buckle at the front end of the handle 3, the middle part of the pull rope is connected to the load block 4 via a lobster buckle on the top surface of the load block 4, and the other end of the pull rope is connected to the sleeve handle 6 via a ring buckle on the sleeve handle 6.

[0031] The method of using this utility model is as follows: When testing the strength of the small boat end of the boat tube 7, the worker fixes the small boat end of the boat tube 7 with the first fixing device 801, places the main body end of the boat tube 7 upward into the gap of the limiting bracket 9, and puts the sleeve 6 on the main body end of the boat tube 7; then the worker presses down on the handle 3, pulls the rope to drive the load block 4 off the ground, and observes whether the boat tube 7 breaks, thereby judging whether the strength of the small boat end of the boat tube 7 is qualified. When testing the strength of the main body end of the boat tube 7, the worker uses a certain weight of load block 4 to suspend the small boat end of the boat tube 7 with qualified strength in advance, and marks it on the workbench 1 according to the position of the small boat end of the boat tube 7 when it falls; during the test, the worker fixes the main body end of the boat tube 7 with the second fixing device 802, and then places the small boat end of the boat tube 7 in the gap corresponding to the second fixing device 802 on the front side of the workbench 1 to complete the installation of the boat tube 7; then the worker presses down on the small boat end of the boat tube 7 by hand. At this point, observe the small boat end of the boat tube 7. If the boat tube 7 does not break, observe whether the distance the small boat end of the boat tube 7 can be pressed down can reach the pre-marked position. This will help determine whether the strength of the main body end of the boat tube 7 is up to standard.

[0032] In this invention, the device uses both pressing the handle 3 and manual pressing to test the strength of the small boat end and the main body end of the boat tube 7, respectively, without requiring additional equipment, thus saving equipment costs. The testing operation is convenient, the process is simple and clear, and the efficiency of testing the strength of the boat tube 7 is improved. Based on the testing requirements of different parts of the boat tube 7, the load block 4 and manual pressing can accurately simulate the stress state of the boat tube 7 in actual use, improving the accuracy of the test results. The device has a simple overall structure, few parts, and low manufacturing cost, facilitating production and large-scale application.
