Description

Technical Field

[0001] This utility model relates to the field of recycling bin technology, and in particular to an immersion-type steel pipe hydrostatic pressure tester. Background Technology

[0002] Hydrostatic pressure testing of steel pipes is an important method for testing the strength and sealing performance of steel pipes. This test involves injecting high-pressure water into the steel pipe and maintaining it for a certain period to test the pipe's pressure resistance under high pressure and to detect any leaks. It can effectively identify defects in the steel pipe, such as cracks, porosity, or poor welding. Hydrostatic pressure testing is a crucial technical means of verifying the pressure resistance of steel pipes. Substandard steel pipes that are prone to bursting or leaking are completely eliminated through hydrostatic pressure testing, allowing for the selection of qualified steel pipes with strong pressure resistance.

[0003] Currently, when conducting hydrostatic pressure testing on steel pipes, the process typically involves first filling the pipe with water using a water pump, then pressurizing it with a high-pressure testing pump, and finally unloading it with an unloading valve. This operation is quite cumbersome, resulting in slow testing speed, low work efficiency, a complicated process, and poor safety due to the large-scale operation on the ground.

[0004] Therefore, it is necessary to provide an immersion-type static water pressure testing machine for steel pipes to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an immersion-type static water pressure testing machine for steel pipes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following solution to the above technical problems: an immersion-type steel pipe hydrostatic pressure tester, comprising a housing, a support plate provided on one side of the housing, a pressure sealing assembly provided directly above the top opening of the housing, an adjustment assembly provided on the support plate to drive the pressure sealing assembly to lift and adjust, multiple insertion ports provided inside the housing, and a second pressure plate provided at the bottom of the housing to cooperate with the pressure sealing assembly.

[0007] As a further embodiment of this utility model, the sealing assembly includes a first pressure plate located directly above the top opening of the housing. The first pressure plate has a cavity inside. An air inlet pipe communicating with the cavity is fixed on the outer wall of the first pressure plate. Multiple air outlets are provided on the bottom surface of the first pressure plate, and the multiple air outlets are arranged in a one-to-one correspondence with multiple insertion ports.

[0008] As a further embodiment of this utility model, a first rubber plate is attached and fixed to the bottom surface of the first pressure plate, and a through hole corresponding to the air outlet is opened on the side of the first rubber plate. A second rubber plate is attached and fixed to the top surface of the second pressure plate.

[0009] As a further embodiment of this utility model, the adjustment assembly includes a drive motor fixed to the top of the support plate, a connecting rod slidably connected to the top of the support plate, a first pressure plate fixed to the bottom of the connecting rod, a rack plate arranged along the length of the connecting rod fixed on the side of the connecting rod, and a gear meshing with the rack plate fixed on the output end of the drive motor.

[0010] As a further embodiment of this utility model, a plurality of symmetrically distributed bottom support rods are fixed on the bottom surface of the box body, and a base plate is fixed to the bottom end of the plurality of bottom support rods. An electric push rod is fixed on the top surface of the base plate, and the second pressure plate is fixed on the output shaft of the electric push rod.

[0011] As a further embodiment of this utility model, a rubber sleeve is provided between the output shaft of the electric push rod and the bottom side wall of the housing.

[0012] As a further embodiment of this utility model, a transparent plate is fixed on the side of the box, and multiple screw holes are provided at the bottom of the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] Multiple steel pipes to be tested are inserted into multiple insertion ports. A movable component moves the sealing component downwards, causing it to simultaneously press down on the tops of the pipes. This seals the tops of the pipes, while a second pressure plate seals the bottoms. The sealing component and the second pressure plate work together to simultaneously seal the tops of the pipes. Gas is then simultaneously delivered into the pipes, creating internal pressure. The pressurized pipes are then placed inside a pressure chamber for pressure testing. This process checks for cracks in the pipe walls and observes for rising air bubbles in the water. This allows for simultaneous pressure testing of multiple pipes in a single operation, significantly reducing testing time, improving efficiency, and lowering labor costs.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Please see Figure 1-6 This utility model provides an immersion-type hydrostatic testing machine for steel pipes, including a housing 3. A support plate 4 is provided on one side of the housing 3. A sealing assembly 1 is provided directly above the top opening of the housing 3. An adjustment assembly 2 is provided on the support plate 4 to drive the sealing assembly 1 to move up and down. Multiple insertion ports 11 are provided inside the housing 3. A second pressure plate 13 that cooperates with the sealing assembly 1 is provided at the bottom of the housing 3. In use, multiple steel pipes to be tested are inserted into the multiple insertion ports 11 respectively. The housing 3 is filled with water. The adjustment assembly 2 drives the sealing assembly 1 to move down, so that the sealing assembly 1 presses down on the top of multiple steel pipes simultaneously, thereby controlling the pressure of the sealing assembly 1. The top ends of multiple steel pipes are simultaneously compressed and sealed, and the bottom ends of the steel pipes are compressed and sealed by the second pressure plate 13. Thus, the top ends of multiple steel pipes are simultaneously compressed and sealed by the pressure sealing component 1 and the second pressure plate 13. Gas is synchronously delivered into the interior of multiple steel pipes through the pressure sealing component 1, so that multiple steel pipes have a certain air pressure. The pressurized steel pipes are then placed into the box 3 for pressure testing. The test checks whether there are cracks on the side walls of the steel pipes and observes whether there are bubbles rising in the water. This allows for simultaneous pressure testing of multiple steel pipes at one time, which greatly shortens the testing time, effectively improves the testing efficiency, and effectively reduces the cost of manual operation.

[0026] Further as Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the pressure sealing assembly 1 includes a first pressure plate 101 located directly above the top opening of the housing 3. The first pressure plate 101 has a cavity 102 inside. An air inlet pipe 105 communicating with the cavity 102 is fixed on the outer wall of the first pressure plate 101. Multiple air outlets 103 are opened on the bottom surface of the first pressure plate 101, and the multiple air outlets 103 are arranged one-to-one with multiple insertion ports 11. An air pump is connected to the air inlet pipe 105. When the bottom surface of the first pressure plate 101 is pressed tightly against the end of the steel pipe, air is delivered to the inside of the first pressure plate 101 through the air inlet pipe 105, and is simultaneously delivered to the inside of multiple steel pipes through the cavity 102 and the multiple air outlets 103, so that the inside of multiple steel pipes has a certain air pressure. The pressurized steel pipes are then placed inside the housing 3, thereby performing a pressure test on the steel pipes to check for cracks on the side walls of the steel pipes and to observe whether there are bubbles rising in the water, thus realizing the synchronous pressure test on multiple steel pipes.

[0027] Further as Figure 4 and Figure 6 As shown, it is worth noting that a first rubber plate 106 is attached and fixed to the bottom surface of the first pressure plate 101, and a through hole 104 corresponding to the air outlet 103 is opened on the side of the first rubber plate 106. A second rubber plate 12 is attached and fixed to the top surface of the second pressure plate 13. In actual operation, the first rubber plate 106 and the second rubber plate 12 effectively increase the sealing performance of the first pressure plate 101 and the second pressure plate 13 to press and seal the two ends of the steel pipe.

[0028] Further as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the adjustment assembly 2 includes a drive motor 5 fixed to the top of the support plate 4. A connecting rod 201 is slidably connected to the top of the support plate 4. A first pressure plate 101 is fixed to the bottom of the connecting rod 201. A rack plate 202 arranged along the length of the connecting rod 201 is fixed on the side of the connecting rod 201. A gear 203 meshing with the rack plate 202 is fixed on the output end of the drive motor 5. In actual operation, the drive motor 5 drives the gear 203 to rotate, thereby driving the connecting rod 201 to move through the cooperation of the gear 203 and the rack plate 202. In turn, the connecting rod 201 drives the first pressure plate 101 to rise and fall to achieve pressure sealing of the steel pipe end.

[0029] Further as Figure 2 , Figure 3 and Figure 6As shown, it is worth noting that multiple symmetrically distributed bottom support rods 8 are fixed on the bottom surface of the box 3. The bottom ends of the multiple bottom support rods 8 are jointly fixed to a bottom plate 9. An electric push rod 7 is fixed on the top surface of the bottom plate 9. The second pressure plate 13 is fixed to the output shaft of the electric push rod 7. After the steel pipes inside the box 3 have completed the pressure test, the first pressure plate 101 moves up to the top of the support plate 4, opening the top of the box 3. The output end of the electric push rod 7 drives the second pressure plate 13 to move up, thereby pushing multiple steel pipes up simultaneously through the second pressure plate 13, thus exposing the top of the steel pipes from inside the box 3, making it easier to remove the steel pipes, effectively improving material handling efficiency and reducing the workload of the staff.

[0030] This solution has the following working process: Multiple steel pipes to be tested are inserted into multiple insertion ports 11. The drive motor 5 drives the gear 203 to rotate, which in turn drives the connecting rod 201 to move downward through the gear 203 and rack plate 202. The connecting rod 201 then drives the first pressure plate 101 to move downward, so that the first pressure plate 101 simultaneously presses down on the top ends of the multiple steel pipes. Thus, the first pressure plate 101 and the second pressure plate 13 work together to simultaneously press and seal the two ends of the multiple steel pipes. Then, air is delivered into the interior of the first pressure plate 101 through the air inlet pipe 105 and simultaneously through the cavity 102 and multiple air outlets 103. The air is pumped into the interior of multiple steel pipes, creating a certain pressure inside them. The pressurized pipes are then placed inside the housing 3 to check for cracks in the sidewalls and observe for rising air bubbles. This allows for simultaneous pressure testing of the multiple pipes. After the pressure test of the pipes inside the housing 3 is completed, the first pressure plate 101 is moved to the top of the support plate 4, opening the top of the housing 3. The output of the electric push rod 7 then moves the second pressure plate 13 upwards, simultaneously lifting the multiple pipes and exposing their tops inside the housing 3 for easy removal.

[0031] Further as Figure 6 As shown, it is worth noting that a rubber sleeve 14 is provided between the output shaft of the electric push rod 7 and the bottom side wall of the housing 3; during operation, the rubber sleeve 14 is provided to prevent water inside the housing 3 from leaking from the output shaft of the electric push rod 7.

[0032] Further as Figure 2 , Figure 4 and Figure 5 As shown, it is worth noting that a transparent plate 6 is fixed on the side of the box 3, and multiple screw holes 10 are opened at the bottom of the support plate 4. During actual operation, the transparent plate 6 allows for easy observation of the air bubbles inside the box 3 and the specific location where the air bubbles occur.

[0033] In summary: By moving the adjusting component 2 downwards, the sealing component 1 simultaneously presses down on the tops of multiple steel pipes, thus simultaneously sealing the tops of the steel pipes. Simultaneously, the second pressure plate 13 seals the bottom of the steel pipes. Through the cooperation of the sealing component 1 and the second pressure plate 13, the tops of the multiple steel pipes are simultaneously sealed. Gas is also simultaneously delivered into the interior of the multiple steel pipes through the sealing component 1, creating a certain air pressure inside. The pressurized steel pipes are then placed inside the housing 3 for pressure testing to check for any defects on the sidewalls. Cracks are observed, and air bubbles are seen rising in the water. This allows for simultaneous pressure testing of multiple steel pipes at once, significantly shortening testing time, improving testing efficiency, and reducing manual operation costs. After the pressure testing of the steel pipes inside the housing 3 is completed, the first pressure plate 101 is moved to the top of the support plate 4, opening the top of the housing 3. The output end of the electric push rod 7 then drives the second pressure plate 13 to move upward, thus simultaneously lifting multiple steel pipes and exposing the tops of the steel pipes from inside the housing 3 for easy removal, effectively improving material handling efficiency and reducing the workload of workers.

[0034] The drive motor 5 and the electric actuator 7 can be purchased from the market. The drive motor 5 and the electric actuator 7 are equipped with a power supply. They are mature technologies in this field and have been fully disclosed. Therefore, they will not be described again in the specification.
