Description

Technical Field

[0001] The utility model relates to a disassembly and assembly device for a sealing ring of a pipe external pressure test. Background Art

[0002] At present, the external pressure test is a test for detecting the performance of pipes in withstanding external pressure. When conducting the external pressure test, the pipe needs to be inserted into the external pressure autoclave and two sealing rings are installed between the pipe and the external pressure autoclave, one in front and one behind, so as to form a sealed annular pressure chamber between the pipe and the external pressure autoclave. By injecting pressure medium into the annular pressure chamber, the performance of the pipe in withstanding external pressure can be detected. Among them, since the pressure injected into the annular pressure chamber can reach hundreds of MPa, in order to prevent leakage, the pre-tightening force of the sealing ring between the pipe and the external pressure autoclave needs to be designed to be larger, which results in a large thrust when installing and removing the sealing ring. Therefore, it is very difficult and inefficient to install and remove the sealing ring only by manpower. However, there is a lack of equipment on the market that can install and remove the sealing ring between the pipe and the external pressure autoclave. Utility Model Content

[0059] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0060] like Figures 1 to 4As shown, a sealing ring disassembly and assembly device for external pressure test of pipes, which is used for disassembly and assembly of a sealing ring 3 between an external pressure autoclave 1 and a pipe 2, comprises a base 4, an autoclave supporting mechanism 5, a left trustee mechanism 6, a right trustee mechanism 7, a left locking mechanism, a right locking mechanism and a pushing mechanism 8;

[0061] The kettle supporting mechanism 5 is connected to the base 4 and is used to support the external pressure kettle 1. The pipe 2 is used to pass through the external pressure kettle 1 and both ends of the pipe 2 are exposed from the external pressure kettle 1. The sealing ring 3 is used to be sleeved on the ends of the pipe 2. An annular pressurized cavity is formed between the external pressure kettle 1 and the pipe 2. When the sealing ring 3 is sleeved on the ends of the pipe 2, the ends of the pipe 2 need to be polished first.

[0062] The left trusteeship mechanism 6 is connected to the base 4 in a sliding manner along the left-right direction, and the left locking mechanism is connected to the left trusteeship mechanism 6 and is used to lock the position of the left trusteeship mechanism 6 when the left trusteeship mechanism 6 slides into place;

[0063] The right trusteeship mechanism 7 is connected to the base 4 in a sliding manner along the left-right direction, and the right locking mechanism is connected to the right trusteeship mechanism 7 and is used to lock the position of the right trusteeship mechanism 7 when the right trusteeship mechanism 7 slides into place;

[0064] The left trustee mechanism 6 is located on the left side of the kettle support mechanism 5 and is used to support the left end of the pipe 2. The left trustee mechanism 6 is also used to abut against the left end surface of the pipe 2 and push the pipe 2 to move rightward when the sealing ring 3 is removed;

[0065] The right supporting mechanism 7 is located on the right side of the kettle supporting mechanism 5 and is used to support the right end of the pipe 2;

[0066] The pushing mechanism 8 is connected to the right trustee mechanism 7 and is used to push the sealing ring 3 sleeved on the right end of the tube 2 to the left between the external autoclave 1 and the tube 2 when installing the sealing ring 3.

[0067] Specifically, the process of installing the sealing ring 3 is as follows: first, the external pressure autoclave 1 is placed on the autoclave supporting mechanism 5 so that the autoclave supporting mechanism 5 supports the external pressure autoclave 1, and the central axis of the external pressure autoclave 1 is arranged in the left-right direction on the autoclave supporting mechanism 5. The pipe 2 is passed through the external pressure autoclave 1, and the sealing ring 3 is sleeved on the end of the pipe 2, so that the left escrow mechanism 6 supports the left end of the pipe 2, and the right escrow mechanism 7 supports the right end of the pipe 2. Then the left escrow mechanism 6 is pressed against the left end face of the pipe 2 and remains motionless, and the sealing ring 3 sleeved on the right end of the pipe 2 is pushed to the left between the external pressure autoclave 1 and the pipe 2 by the pushing mechanism 8, thereby completing the installation of the first sealing ring 3. After the first sealing ring 3 is installed, the external pressure autoclave 1 and the pipe 2 are lifted up together and then turned around to achieve left-right swapping. Then, the external pressure autoclave 1 and the pipe 2 are lowered again so that the autoclave supporting mechanism 5 can support the external pressure autoclave 1 again, and the left trusteeship mechanism 6 and the right trusteeship mechanism 7 can support the two ends of the pipe 2 again. At this time, the left and right sides of the pipe 2 have been swapped. The sealing ring 3 on the right end of the pipe 2 is pushed to the left between the external pressure autoclave 1 and the pipe 2 by the pushing mechanism 8, thereby completing the installation of the second sealing ring 3.

[0068] The process of disassembling the sealing ring 3 is as follows: after the test, the external autoclave 1 and the pipe 2 are placed together on the autoclave supporting mechanism 5 so that the autoclave supporting mechanism 5 supports the external autoclave 1, the left trustee mechanism 6 supports the left end of the pipe 2, and the right trustee mechanism 7 supports the right end of the pipe 2. Then the left trustee mechanism 6 presses against the left end face of the pipe 2 and pushes the pipe 2 to move to the right, thereby bringing the sealing ring 3 at the right end out of the external autoclave 1, thereby completing the disassembly of the first sealing ring 3. After the first sealing ring 3 is disassembled, the external pressure autoclave 1 and the pipe 2 are lifted together and then turned to achieve left-right swapping, and then the external pressure autoclave 1 and the pipe 2 are lowered again so that the autoclave supporting mechanism 5 can support the external pressure autoclave 1 again, and the left and right supporting mechanisms 6 and 7 can support the two ends of the pipe 2 again. At this time, the left and right sides of the pipe 2 have been swapped, and the left supporting mechanism 6 is used to press against the left end face of the pipe 2 and push the pipe 2 to move to the right, thereby bringing the second sealing ring 3 out of the external pressure autoclave 1, and then completing the disassembly of the second sealing ring 3. The pipe external pressure test sealing ring disassembly and assembly device of the embodiment of the present application can be used to install and disassemble the sealing ring 3 between the pipe 2 and the external pressure autoclave 1, which greatly improves the efficiency and convenience of disassembly and assembly of the sealing ring 3.

[0069] Specifically, the left escrow mechanism 6 and the right escrow mechanism 7 can both slide in the left and right directions, so that the positions of the left escrow mechanism 6 and the right escrow mechanism 7 can be adjusted according to the length of the pipe 2, which is also conducive to improving the convenience of loading and unloading the pipe 2. In addition, when the left escrow mechanism 6 slides into place, the position of the left escrow mechanism 6 can be locked by the left locking mechanism, and when the right escrow mechanism 7 slides into place, the position of the right escrow mechanism 7 can be locked by the right locking mechanism.

[0077] Specifically, when installing the sealing ring 3, the horizontal pushing mechanism 10 presses against the left end face of the pipe 2 and remains stationary, and the pushing mechanism 8 pushes the sealing ring 3 sleeved on the right end of the pipe 2 to the left between the external autoclave 1 and the pipe 2 to complete the installation of the sealing ring 3. When removing the sealing ring 3, the horizontal pushing mechanism 10 presses against the left end face of the pipe 2 and pushes the pipe 2 to the right, thereby bringing the sealing ring 3 out of the external autoclave 1 to complete the removal of the sealing ring 3. More specifically, the left lifting mechanism 9 can drive the horizontal pushing mechanism 10 to move up and down, thereby adjusting the height of the left end of the pipe 2; the right lifting mechanism 11 can drive the supporting component 12 and the pushing mechanism 8 to move up and down, thereby adjusting the height of the right end of the pipe 2, thereby adjusting the overall height and horizontal state of the pipe 2.

Specifically, first, the supporting mechanism 5 supports the external pressure autoclave 1, the pipe 2 passes through the external pressure autoclave 1, and the sealing ring 3 is sleeved on the end of the pipe 2.

[0106] The central axis of the first right supporting wheel 34 and the central axis of the second right supporting wheel 35 are respectively perpendicular to the central axis of the pipe 2. The purpose of this design is that when the sealing ring 3 is removed, the pipe 2 can move to the right with the support of the first right supporting wheel 34 and the second right supporting wheel 35.

[0107] like Figures 2 to 4 As shown, the pipe external pressure test seal ring disassembly and assembly device may further include a blocking plate 36, and the base 4 may be provided with a left slot 37 and a right slot 38;

[0108] The blocking plate 36 is used to be inserted into the left slot 37 when the sealing ring 3 is installed and to abut against the left end of the external autoclave 1 to prevent the external autoclave 1 from moving leftward.

[0109] The blocking plate 36 is also used to be inserted into the right slot 38 and to abut against the right side end of the external pressure autoclave 1 when the sealing ring 3 is disassembled to prevent the external pressure autoclave 1 from moving to the right; in this embodiment, two of the blocking plates 36, the left slot 37 and the right slot 38 are respectively provided.

The outer wheel circumference of the second support wheel 41 protrudes from the second groove wall and is used to support the outer side wall of the external autoclave 1; in this embodiment, the pipe 2 can be a seamless steel pipe.

[0114] In summary, the process of installing the sealing ring 3 is as follows: first, the external autoclave 1 is placed on the autoclave supporting mechanism 5 so that the autoclave supporting mechanism 5 supports the external autoclave 1, and the central axis of the external autoclave 1 is arranged in the left-right direction on the autoclave supporting mechanism 5. The pipe 2 is passed through the external autoclave 1, and the sealing ring 3 is sleeved on the end of the pipe 2, so that the left trustee mechanism 6 supports the left end of the pipe 2, and the right trustee mechanism 7 supports the right end of the pipe 2. Then the left trustee mechanism 6 is pressed against the left end face of the pipe 2 and remains motionless, and the sealing ring 3 sleeved on the right end of the pipe 2 is pushed to the left between the external autoclave 1 and the pipe 2 by the pushing mechanism 8, thereby completing the installation of the first sealing ring 3. After the first sealing ring 3 is installed, the external pressure autoclave 1 and the pipe 2 are lifted up together and then turned around to achieve left-right swapping. Then, the external pressure autoclave 1 and the pipe 2 are lowered again so that the autoclave supporting mechanism 5 can support the external pressure autoclave 1 again, and the left trusteeship mechanism 6 and the right trusteeship mechanism 7 can support the two ends of the pipe 2 again. At this time, the left and right sides of the pipe 2 have been swapped. The sealing ring 3 on the right end of the pipe 2 is pushed to the left between the external pressure autoclave 1 and the pipe 2 by the pushing mechanism 8, thereby completing the installation of the second sealing ring 3.

[0115] The process of disassembling the sealing ring 3 is as follows: after the test, the external autoclave 1 and the pipe 2 are placed together on the autoclave supporting mechanism 5 so that the autoclave supporting mechanism 5 supports the external autoclave 1, the left trustee mechanism 6 supports the left end of the pipe 2, and the right trustee mechanism 7 supports the right end of the pipe 2. Then the left trustee mechanism 6 presses against the left end face of the pipe 2 and pushes the pipe 2 to move to the right, thereby bringing the sealing ring 3 at the right end out of the external autoclave 1, thereby completing the disassembly of the first sealing ring 3. After the first sealing ring 3 is disassembled, the external pressure autoclave 1 and the pipe 2 are lifted together and then turned to achieve left-right swapping, and then the external pressure autoclave 1 and the pipe 2 are lowered again so that the supporting mechanism 5 can support the external pressure autoclave 1 again, and the left and right supporting mechanisms 6 and the right supporting mechanisms 7 can support the two ends of the pipe 2 again. At this time, the left and right sides of the pipe 2 have been swapped, and the left supporting mechanism 6 is pressed against the left end face of the pipe 2 at this time and pushes the pipe 2 to move to the right, thereby bringing the second sealing ring 3 out of the external pressure autoclave 1, and then completing the disassembly of the second sealing ring 3. The pipe external pressure test sealing ring disassembly and assembly device of the embodiment of the present application can be used to install and disassemble the sealing ring 3 between the pipe 2 and the external pressure autoclave 1, which greatly improves the efficiency and convenience of disassembly and assembly of the sealing ring 3. The left and right supporting mechanisms 6 and the right and right supporting mechanisms 7 can slide in the left and right directions, so that the positions of the left and right supporting mechanisms 6 and the right and right supporting mechanisms 7 can be adjusted according to the length of the pipe 2, which is also conducive to improving the convenience of loading and unloading the pipe 2. Furthermore, when the left trusteeship mechanism 6 slides into place, the position of the left trusteeship mechanism 6 can be locked by the left locking mechanism, and when the right trusteeship mechanism 7 slides into place, the position of the right trusteeship mechanism 7 can be locked by the right locking mechanism.
