[0002] A high-pressure vessel is a pressure vessel with a design pressure p in the range of 10.0 MPa ≤ p < 100.0 MPa, and it is widely used. For example, the outer shells of high-pressure heaters used in power plants, ammonia synthesis towers, urea synthesis towers, copper scrubbing towers, and carbon monoxide cold extraction towers in the chemical industry all belong to high-pressure vessels. During the production and manufacturing process of high-pressure vessels, multiple performance indicators are usually tested to ensure the finished product quality of high-pressure vessels.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present utility model are given for the purpose of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and design various embodiments with various modifications suitable for specific purposes.

[0021] As Figures 1-3 shown, a testing tooling for a high-pressure vessel 1 includes an upper pressure member that sleevingly limits the top of the high-pressure vessel 1 and a lower pressure member that sleevingly limits the bottom of the high-pressure vessel 1. A fixing plate 2 is connected between the lower pressure member and the upper pressure member. A support seat 3 is installed at the bottom of the fixing plate 2. A clamping member that moves back and forth is installed on the front side wall of the fixing plate 2. The high-pressure vessel 1 to be tested is placed between the clamping member, the upper pressure member and the lower pressure member. The clamping member moves back and forth to clamp and limit both sides of the high-pressure vessel 1.

[0022] Based on the above, during use, the high-pressure vessel 1 to be tested is placed between the upper pressure member and the lower pressure member. The upper pressure member and the lower pressure member are used to fasten and limit the high-pressure vessel 1 in the vertical direction. Then, the clamping member that moves back and forth on the fixing plate 2 is used to clamp and fix both sides of the high-pressure vessel 1.

[0023] Furthermore, both the upper pressure member and the lower pressure member are components that can be lifted and moved. In cooperation with the clamping member that can move back and forth, during the process of testing the high-pressure vessel 1, high-pressure vessels 1 of different sizes can be clamped and positioned, and the applicable range is wide.

[0024] The upper pressure member includes an equipment top plate 4 fixed to the top of the fixing plate 2. The equipment bottom plate is located above the support seat 3. An upper pressure seat 5 is installed at the bottom of the equipment top plate 4. A plurality of first hydraulic push rods 6 are installed at the bottom of the upper pressure seat 5. A circular upper pressure ring 7 is connected to the bottom ends of the output shafts of the plurality of hydraulic push rods.

[0025] Based on the above, during the working process of the upper pressure member, a plurality of first hydraulic push rods 6 are simultaneously activated to push the upper pressure ring 7 to displace, so that the upper pressure ring 7 acts on the top of the high-pressure vessel 1.

[0026] A plurality of first telescopic rods 8 are connected between the upper pressure ring 7 and the upper pressure seat 5. An upper rubber sleeve 9 is sleeved on the bottom of the upper pressure ring 7.

[0027] The first telescopic rod 8 provides limit and stability for the displacement of the upper pressure ring 7. The upper rubber sleeve 9 buffers when the upper pressure ring 7 contacts the top end of the high-pressure vessel 1, and the upper rubber sleeve 9 is used to fit and clamp the top end of the high-pressure vessel 1, making the clamping more stable and not easy to shake.

[0028] The lower pressure member includes a lower pressure seat 10 installed on the surface of the support base 3. A plurality of second hydraulic push rods 11 are installed on the top of the lower pressure seat 10, and a circular lower pressure ring 12 is connected to the top ends of the output shafts of the plurality of second hydraulic push rods 11;

[0029] A plurality of second telescopic rods 13 are connected between the lower pressure ring 12 and the lower pressure seat 10, and a lower rubber sleeve 14 is sleeved on the top of the lower pressure ring 12;

[0030] Based on the above, during operation, first, according to the size of the high-pressure vessel 1, adjust the distance that the plurality of second hydraulic push rods 11 extend. After adjusting the height of the lower pressure ring 12, place the bottom end of the high-pressure vessel 1 into the lower pressure ring 12, and the bottom end of the high-pressure vessel 1 is fitted and clamped with the lower rubber sleeve 14. Then, control the upper pressure member to work, so that the upper pressure ring 7 moves down and sleeves on the top end of the high-pressure vessel 1. The upper pressure ring 7 and the lower pressure ring 12 cooperate to complete the preliminary fixation of the high-pressure vessel 1.

[0031] The lower pressure ring 12 is located directly below the upper pressure ring 7. Both the upper pressure seat 5 and the lower pressure seat 10 are circular rings with hollow interiors. Connecting holes 15 are provided on both the equipment top plate 4 and the support base 3, and the connecting holes 15 are used for connecting pipeline components and routing wires of the high-pressure vessel 1.

[0032] The clamping member includes a bearing 16 fixed in the middle of the fixing plate 2, and two clamping plates 17 symmetrically arranged on both sides of the fixing plate 2 through the bearing 16. A telescopic and movable third telescopic rod 18 is connected between the top and bottom of the two clamping plates 17, and a rotating adjustment screw 19 is inserted into the bearing 16;

[0033] Solenoid tubes 20 are installed on the outer walls of the two clamping plates 17 away from each other. Both ends of the adjustment screw 19 penetrate through the clamping plates 17 and extend to both sides of the fixing plate 2 through the solenoid tubes 20, and a turntable 21 is installed at the end of one end of the adjustment screw 19;

[0034] Two sections of threads are provided on the outer wall of the adjustment screw 19. The two sections of threads are symmetrically arranged through the bearing 16 and have opposite thread directions.

[0035] Based on the above, after the high-pressure container 1 is initially fixed and limited by the upper pressure piece and the lower pressure piece, the rotating turntable 21 drives the adjusting screw 19 to rotate in the bearing 16, and the two sections of threads in opposite directions on the outer wall of the adjusting screw 19 are matched with the two screw tubes 20 on both sides, so as to push the two clamping plates 17 on both sides closer to each other, so that the two clamping plates 17 are attached to the two sides of the high-pressure container 1, and the two sides of the high-pressure container 1 are limited in the horizontal direction, so as to achieve the clamping and positioning of the high-pressure container 1.

[0036] Furthermore, when the two clamping plates 17 are approaching each other, the third telescopic rod 18 limits the movement of the two clamping plates 17 to avoid unnecessary shaking.

[0037] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
