[0002] In the process of ship research, it is often necessary to conduct tank tests on test pieces to examine their working conditions in the water. Since the test pieces have different shapes and are usually large, the existing technology usually uses a crane to directly lift them into the tank for testing. Since the test pieces also need to move in the tank, the operation is cumbersome and requires the cooperation of multiple test personnel. The overall work reliability is poor and there are certain safety hazards. If you encounter a special-shaped test piece, there will be problems such as difficulty in lifting. Summary of the invention

[0003] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides a large-opening water immersion test platform and test method, which can conveniently complete the immersion of test pieces in water and their movement in water, which will significantly reduce the workload of operators and improve operation safety and efficiency.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A large-opening water immersion test platform comprises a large water pool, tracks are fixed on both sides of the top surface of the large water pool, and a workbench. Four walking mechanisms are arranged at the bottom of the workbench, the walking mechanisms match the tracks, and the workbench slides along the tracks through the walking mechanisms; a square opening is arranged in the middle of the workbench, a supporting frame is fixed on the workbench around the square opening, two groups of electric hoists are installed on each side of the supporting frame, the electric hoists are installed with a lifting platform through cables, and the size of the lifting platform matches the square opening; a synchronous control system is also fixed on the workbench, and the synchronous control system controls the synchronous operation of the four groups of electric hoists and the walking mechanisms.

[0006] Its further technical solution is:

[0007] The lifting platform adopts an integrated structure.

[0008] The lifting platform is formed by welding steel structures.

[0009] The lifting platform is provided with a plurality of groups of evenly distributed rectangular holes.

[0010] Connecting seats are respectively fixed at the four corners of the top surface of the lifting platform, and the connecting seats are fixed to the cables.

[0011] The connecting seat is in a trapezoidal structure.

[0012] The large pool and the workbench are both equipped with fences.

[0013] A test method for a large-opening water immersion test platform includes the following operation procedures:

[0014] Step 1: Start the synchronous control system, control the operation of the electric hoist, and lift the lifting platform to the highest position. At this time, the lifting platform is flush with the square opening;

[0015] Step 2: Hoist the test piece onto the lifting platform and fix it to complete the test preparation;

[0016] Step 3: Control the electric hoist to lower the lifting platform to the predetermined depth;

[0017] Step 4: Control the walking mechanism to move along the track at a constant speed, driving the test piece to move in the water;

[0018] Step 5: Complete the experiment;

[0019] Step 6: Raise the lifting platform to the highest position again;

[0031] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0032] like Figure 1-Figure 5 As shown, the large-opening water immersion test platform of this embodiment includes a large water pool 1, with tracks 2 fixed on both sides of the top surface of the large water pool 1, and also includes a workbench 6. Four walking mechanisms 3 are arranged at the bottom of the workbench 6, and the walking mechanisms 3 match the tracks 2. The workbench 6 slides along the tracks 2 through the walking mechanisms 3; a square opening is arranged in the middle of the workbench 6, and a supporting frame 4 is fixed on the workbench 6 around the square opening. Two groups of electric hoists 5 are installed on both sides of the supporting frame 4, and the electric hoists 5 are installed with a lifting platform 7 through cables 9, and the size of the lifting platform 7 is consistent with the square opening; a synchronous control system 8 is also fixed on the workbench 6, and the synchronous control system 8 controls the synchronous operation of the four groups of electric hoists 5 and the walking mechanisms 3.

[0033] The lifting platform 7 adopts an integrated structure.

[0034] The lifting platform 7 is formed by welding a steel structure.

[0035] The lifting platform 7 is provided with a plurality of evenly distributed rectangular holes.

[0036] Connecting seats 10 are fixed to the four corners of the top surface of the lifting platform 7 , respectively, and the connecting seats 10 are fixed to the cables 9 .

[0037] The connecting seat 10 has a trapezoidal structure.

[0038] Fences 11 are installed on the large pool 1 and the workbench 6 .

[0039] The test method of the large-opening water immersion test platform of this embodiment includes the following operation procedures:

[0040] Step 1: Start the synchronous control system 8, control the electric hoist 5 to operate, and lift the lifting platform 7 to the highest position, at which time the lifting platform 7 is flush with the square opening;

[0041] Step 2: hoist the test piece onto the lifting platform 7 and fix it to complete the test preparation;

[0042] Step 3: Control the electric hoist 5 to lower the lifting platform 7 to a predetermined depth position;

[0043] Step 4: Control the walking mechanism 3 to move along the track 2 at a constant speed, driving the test piece to move in the water;

[0044] Step 5: Complete the experiment;

[0045] Step 6: Raise the lifting platform 7 to the highest position again;

[0046] Step 7: Remove the test piece;

[0047] Step 8: Wait for the next experiment.

[0048] The specific structure and function of the large-opening water immersion test platform described in the present invention are as follows:

[0049] It mainly includes components such as track 2, walking mechanism 3, supporting frame 4, electric hoist 5, workbench 6, lifting platform 7 and synchronous control system 8.

[0050] Among them, two tracks 2 are fixed in parallel on both sides of the large pool 1.

[0051] Among them, the workbench 6 is placed above the track 2 through four walking mechanisms 3. A square opening is set in the middle of the workbench 6, which is convenient for installing the test piece when the lifting platform 7 is at the highest position. At the same time, the square opening is relatively large and can accommodate test pieces of various sizes, regardless of the shape of the test piece, making the work convenient and flexible.

[0052] The support frame 4 is fixed around the square opening of the workbench 6 , and two sets of electric hoists 5 are installed on both sides of the support frame 4 . The electric hoists 5 are fixed to four connecting seats 10 of the lifting platform 7 through cables 9 .

[0053] The synchronous control system 8 is fixed on the workbench 6 and is used to control the synchronous operation of the four sets of electric hoists 5 and the walking mechanism 3 to achieve the smooth rising and lowering of the lifting platform 7 and the horizontal walking in the large water pool 1.

[0054] In actual working process:

[0055] First, start the synchronous control system 8 to control the operation of the electric hoist 5 to lift the lifting platform 7 to the highest position. Figure 4 and Figure 5 As shown, at this time, the lifting platform 7 is flush with the square opening.

[0056] Then, the test piece is hoisted onto the lifting platform 7 and fixed, completing the test preparation work.

[0057] Subsequently, the synchronous control system 8 controls the electric hoist 5 to lower the lifting platform 7 to a predetermined depth.

[0058] Finally, the synchronous control system 8 is used to control the walking mechanism 3 to move along the track 2 at a certain speed, thereby driving the test piece to move in the water.

[0059] The present invention realizes the immersion of the test piece in water and the movement of the test piece in water through an automated water immersion test platform, which will significantly reduce the workload of operators and improve operation safety and efficiency.
