For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0036] Please refer to the attached Figure 1 To Attachment Fig.13 The test fixture of the large deepwater jacket leveler 6 of the utility model is described.

[0037] Due to the large size and high mass of a large deepwater jacket, it is difficult to test the reliability of the existing leveler 6 in actual use.

[0038] Therefore, the utility model provides a test tool for a large deepwater jacket leveler 6, such as Figure 1 As shown, it includes a bottom tooling 1, to which a leveling ring 4 is fixedly connected, so that a leveler 6 can be abutted and clamped, a variable-diameter steel pile 2 is connected to the bottom tooling 1, and a steel pile 3 is connected to the variable-diameter steel pile 2, so that the bottom tooling 1, the variable-diameter steel pile 2 and the steel pile 3 together form a simulated conductor frame pile leg, and the leveler 6 is abutted and clamped against the leveling ring 4, so as to test the reliability of the leveler 6 under different working conditions.

[0039] like Figure 2 and Figure 3 As shown, the bottom tooling 1 includes a bottom plate 101, to which a vertical cylinder 102 is fixedly connected. The center of the bottom plate 101 and the center of the vertical cylinder 102 are on the same vertical line to ensure uniform force on the bottom tooling 1. The bottom tooling 1 is connected to the variable diameter steel pile 2 through the vertical cylinder 102.

[0040] The center of the bottom plate 101 and the center of the leveling ring 4 are on the same vertical line to ensure uniform force on the bottom tooling 1. The diameter of the leveling ring 4 is larger than the diameter of the vertical cylinder 102 so that an accommodating space for the leveler 6 is formed between the leveling ring 4 and the vertical cylinder 102.

[0041] A bottom cylinder 103 is fixedly connected to the bottom plate 101, and the diameter of the bottom cylinder 103 is the same as the diameter of the leveling ring 4. The end of the bottom cylinder 103 away from the bottom plate 101 is fixedly connected to the leveling ring 4, so that the bottom tooling 1 is fixedly connected to the leveling ring 4. Specifically, the bottom tooling 1 is fixedly connected to the leveling ring 4 through the bottom cylinder 103 to prevent water from accumulating at the bottom of the bottom tooling 1 and corroding the leveling ring 4.

[0042] Preferably, in order to improve the structural strength of the bottom tooling 1, an inner rib plate 104 is fixedly connected to the bottom plate 101, one end of the inner rib plate 104 is fixedly connected to the outer wall of the vertical tube 102, one end of the inner rib plate 104 away from the vertical tube 102 is fixedly connected to the inner wall of the bottom tube 103, and an outer rib plate 105 is fixedly connected to the bottom plate 101, one end of the outer rib plate 105 is fixedly connected to the outer wall of the bottom tube 103.

[0044] In order to facilitate drainage of the bottom tooling 1, the inner wall of the first ring plate 106 is fixedly connected to the vertical tube 102, a gap is arranged between the outer wall of the first ring plate 106 and the inner wall of the bottom tube 103, and a drainage hole is opened in the circular bottom area where the bottom plate 101 and the bottom tube 103 are fixedly connected. Specifically, the accumulated water enters from the top of the bottom tooling 1, a part of the accumulated water entering the vertical tube 102 flows out through the drainage hole inside the vertical tube 102, and a part of the accumulated water entering between the vertical tube 102 and the leveling ring 4 flows out from the drainage hole between the vertical tube 102 and the bottom tube 103 through the gap, thereby achieving the effect of drainage.

[0045] Preferably, the drainage holes between the vertical tube 102 and the bottom tube 103 are staggered with the inner rib plate 104 to avoid the drainage holes and the inner rib plate 104 overlapping and thus affecting the drainage effect and structural strength of the bottom tooling 1.

[0046] Preferably, a bell mouth 41 is fixedly connected to the leveling ring 4 to facilitate the installation of the leveler 6 and to guide the installation of the leveler 6 .

The first cylinder 201 and the second cylinder 202 are fixedly connected by a second ring plate 203. The variable diameter steel pile 2 is detachably connected to the vertical cylinder 102 through the first cylinder 201, so that the variable diameter steel pile 2 is detachably connected to the bottom tooling 1, which is convenient for installation and disassembly of the device.

[0048] The inner wall of the first cylinder 201 of the variable diameter steel pile 2 is fixedly connected with a first guide rib 204, and the first guide rib 204 is arranged circumferentially along the inner wall of the first cylinder 201. A plurality of first guide ribs 204 surround a vertical cylinder 102 accommodating cavity that matches the vertical cylinder 102, so that the variable diameter steel pile 2 is detachably connected to the bottom tooling 1.

[0049] Preferably, the first guide rib 204 is provided with a chamfer to compensate for the tolerance between the first guide rib 204 and the vertical cylinder 102 , so as to facilitate the first cylinder 201 to be detachably sleeved on the vertical cylinder 102 .

[0050] Preferably, a reinforcing rib plate 205 is circumferentially fixedly connected to the connection between the first cylinder 201 and the second ring plate 203 to improve the structural strength of the connection, thereby ensuring the overall structural rigidity of the variable diameter steel pile 2.

[0051] like Figure 6 and Figure 7 As shown, the inner wall of the steel pile 3 is fixedly connected with a second guide rib 301, and the second guide rib 301 is circumferentially arranged along the inner wall of the steel pile 3. A plurality of second guide ribs 301 surround a second cylinder 202 accommodating cavity that matches the second cylinder 202, so that the steel pile 3 and the variable diameter steel pile 2 can be detachably connected, which is convenient for installation and disassembly of the device.

[0053] It should be noted that the width of the second guide rib 301 of steel piles 3 of different sizes can be determined according to the inner diameter of the steel pile 3 and the outer diameter of the second cylinder 202 of the variable-diameter steel pile 2, to ensure that it plays a positioning role during the installation process and can also meet the requirement of no bumps.

[0054] The inner walls of the vertical tube 102, the variable diameter steel piles 2 and the steel piles 3 are fixedly connected with lifting ears 5 for hooking, so as to facilitate the assembly and disassembly of the device.

[0056] Preferably, the lifting lugs 5 of the vertical tube 102, the lifting lugs 5 of the variable-diameter steel piles 2, and the lifting lugs 5 of the steel piles 3 are all provided with four in the circumference to facilitate smooth lifting by the crane.

[0057] like Figure 8 and Fig. 9 As shown, under the functional test condition of the leveler 6, the bottom tooling 1 is placed on the ground, the claws of the lower ring body of the leveler 6 abut against and clamp the leveling ring 4, and the function of the hydraulic press and electronic control system of the leveler 6 is tested, specifically whether the clamping devices of the upper and lower ring bodies can work normally and whether the oil cylinder of the leveler 6 can move normally.

The leveler 6 is inserted into the device, and the emergency unlocking system of the leveler 6 is started to simulate the situation where the hydraulic system of the upper and lower ring body claws of the leveler 6 is damaged, and whether the leveler 6 can be removed from the leveling ring 4 and the steel pile 3.

[0059] like Fig.12 and Fig.13 As shown, under the load test condition of the leveler 6, the bottom tooling 1 is placed on the ground, the variable diameter steel pile 2 is placed on the upper part of the bottom tooling 1, and the steel pile 3 is placed on the upper part of the variable diameter steel pile 2, which can simulate the working positions of the steel pile 3, the skirt pile conductor frame, and the leveler 6.
