Description

Technical Field

[0001] This utility model relates to the field of end cap testing technology, specifically to a jacketed end cap deformation testing device. Background Technology

[0002] As a key component of pressure vessels (such as storage tanks and reactors), end caps are commonly spherical or elliptical in shape. Changes in their shape can affect the overall strength and sealing performance of the vessel. Deformation testing can determine whether the end cap will deform excessively under conditions such as internal pressure, external load, or temperature changes, thereby preventing safety accidents such as rupture and leakage caused by excessive deformation.

[0003] Chinese patent (authorization announcement number: CN 221224397 U, authorization announcement date: 2024.06.25) proposes a head deformation testing device. This patent has a testing component set on the top of the table. By setting the testing component to test the deformation shape of the head after it is subjected to different forces against the detection head, the device can determine whether the current head performance is qualified. This effectively solves the problem that the existing testing devices can only test the airtightness of the head, but cannot test the deformation of the head under force.

[0004] When using this patent, the end cap must first be fixed to the fixed plate with bolts, and then the fixed plate is lowered by a hydraulic cylinder to squeeze the bottom of the end cap against the detection head, thereby performing a deformation test on the end cap. However, this method can only perform deformation tests on the bottom of the end cap, and the removal and placement of the end cap during the test is relatively troublesome. In order to perform deformation tests on any position of the end cap, make the test results more comprehensive, and improve the efficiency of removing and placing the end cap during the test, we propose a jacketed end cap deformation testing device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4This utility model provides a technical solution: a jacketed end cap deformation testing device, including a cabinet 1, a number of support rods 2 fixedly connected to the top of the cabinet 1, a top plate 4 fixedly connected to the top of the support rods 2, a test cylinder 5 fixedly installed on the top of the top plate 4, a number of lifting hydraulic cylinders 9 fixedly installed on the top of the cabinet 1, a lifting plate 3 fixedly connected to the output end of the lifting hydraulic cylinder 9, the support rods 2 slidingly passing through the lifting plate 3, the lifting plate 3 having through holes for the end cap to pass through, a number of test hydraulic cylinders 7 fixedly installed on the top of the lifting plate 3, a fixing component for fixing the position of the end cap installed on the cabinet 1, a rotating component for driving the end cap to rotate installed on the cabinet 1, the fixing component including a support cylinder 8, the support cylinder 8 fixedly connected to the top of the cabinet 1.

[0022] In use, the end cap is first fixed in position by fixing components to prevent the end cap from moving and affecting the test results. Then, the deformation test of the bottom of the end cap can be performed by the test cylinder 5. The end cap can be rotated under the action of the rotating component. Under the action of the lifting hydraulic cylinder 9, the lifting plate 3 can drive the test hydraulic cylinder 7 to move up and down. The deformation test of any position of the end cap except the bottom can be performed by the test hydraulic cylinder 7, so that the test results are more comprehensive.

[0023] The fixing assembly also includes a rotating plate 19, which is rotatably connected to the top of the support cylinder 8. Several sets of connecting rods 17 are fixedly connected to the top of the rotating plate 19, and a fixing ring 16 is fixedly connected to the top of the connecting rods 17. A connecting plate 13 is rotatably sleeved on the output end of the test cylinder 5. Several sets of telescopic rods 15 are fixedly connected to the bottom of the connecting plate 13. A fixing plate 12 is fixedly connected to the bottom of the telescopic rods 15. A fixing spring 14 is fixedly connected to the top of the fixing plate 12. The top of the fixing spring 14 is fixedly connected to the bottom of the connecting plate 13.

[0024] Place the end cap in the fixing ring 16, start the test cylinder 5 to drive the connecting plate 13 down, which in turn drives the fixing plate 12 down. After the outer side of the fixing plate 12 abuts against the inner wall of the end cap, the connecting plate 13 is lowered a further distance. Under the action of the fixing spring 14, the fixing plate 12 is fixed between the fixing plate 12 and the fixing ring 16. The end cap is easy to pick up and put down, and the work efficiency is high.

[0025] The rotating assembly includes a stress relief spring 21, which is fixedly installed on the top of the cabinet 1. A mounting plate 22 is fixedly connected to the top of the stress relief spring 21. The outer side of the mounting plate 22 is rotatably connected to the inner wall of the support cylinder 8. A motor 20 is fixedly installed on the top of the mounting plate 22. The output end of the motor 20 is fixedly connected to the bottom of the rotating plate 19.

[0026] After the end cap is fixed by the fixing components, the motor 20 is started, which drives the rotating plate 19 to rotate. The connecting rod 17 causes the fixing ring 16 to rotate. Since the end cap is clamped between the fixing ring 16 and the fixing plate 12, the fixing ring 16 rotates under the action of friction, which drives the end cap to rotate. Under the action of the lifting hydraulic cylinder 9, the lifting plate 3 can drive the test hydraulic cylinder 7 to move up and down. The test hydraulic cylinder 7 can be used to perform deformation testing on any position of the end cap except the bottom. The unloading spring 21 can prevent the output end of the motor 20 from bearing pressure and extend the service life of the equipment.

[0027] The output end of the test cylinder 5 is fixedly connected to a second pressure head 6. The second pressure head 6 moves through the fixing plate 12. When the fixing plate 12 presses against the end cap to fix it, the second pressure head 6 does not contact the inner wall of the end cap. By controlling the test cylinder 5 to drive the second pressure head 6 to continuously descend, the deformation test of the bottom of the end cap can be performed. The use of the fixing component is not affected during the test. The output end of the test hydraulic cylinder 7 is fixedly connected to a first pressure head 18. Both the first pressure head 18 and the second pressure head 6 are wrapped with a rubber layer to avoid damage to the surface of the end cap during the test.

[0028] The support cylinder 8 has several sets of through holes to facilitate heat dissipation of the motor 20 and extend the service life of the equipment.

[0029] Several sets of casters 11 are fixedly connected to the bottom of the cabinet 1 to facilitate moving the equipment to a suitable position. A controller 10 is fixedly installed on the front of the cabinet 1 to adjust various parameters and control the operation of the equipment.

[0030] Working principle: In use, the end cap is placed in the fixing ring 16. The test cylinder 5 is activated to lower the connecting plate 13, which in turn lowers the fixing plate 12. After the outer side of the fixing plate 12 abuts against the inner wall of the end cap, the test cylinder 5 is controlled to lower the connecting plate 13 a further distance. Under the action of the fixing spring 14, the fixing plate 12 is fixed between the fixing plate 12 and the fixing ring 16. This makes it easy to pick up and put down the end cap and improves work efficiency. At this time, the second pressure head 6 has not yet contacted the inner wall of the end cap. By controlling the test cylinder 5 to drive the second pressure head 6 to continue to descend, the deformation test of the bottom of the end cap can be performed. The use of the fixing components is not affected during the test. After the end cap is fixed, the motor 20 is started, which drives the rotating plate 19 to rotate. The connecting rod 17 causes the fixing ring 16 to rotate. Since the end cap is clamped between the fixing ring 16 and the fixing plate 12, the fixing ring 16 rotates under the action of friction, which drives the end cap to rotate. The unloading spring 21 can prevent the output end of the motor 20 from bearing pressure and extend the service life of the equipment. Under the action of the lifting hydraulic cylinder 9, the lifting plate 3 can drive the test hydraulic cylinder 7 to move up and down. The test hydraulic cylinder 7 can be used to perform deformation testing on any position of the end cap except the bottom, thereby realizing deformation testing on any position of the end cap and making the test results more comprehensive.
