[0032] like Figure 1 As shown, the upper surface of the base plate 1 gradually increases from the left side to the right side of the base plate 1.

[0033] The top ends of the left side plate 2 and the right side plate 3 are slidably connected to a top plate 8, and the left and right sides of the upper surface of the bottom plate 1 are fixedly installed with a first electric push rod 9, and the output end of the first electric push rod 9 is fixedly connected to the top plate 8, and the left and right sides of the lower surface of the top plate 8 are fixedly connected with a main clamping seat 10 corresponding to the main supporting base 5. The main supporting base 5 and the main clamping seat 10 are used to fix the oil pipe to be inspected, and a knocking component 11 for knocking the oil pipe is arranged below the top plate 8.

[0034] like Figure 1 and Figure 5 As shown, in this embodiment, a first groove 501 is formed on the upper surface of the main support base 5, and a first rubber pad is fixedly connected to the inner wall of the first groove 501, and the inner surface shape of the first rubber pad matches the outer surface shape of the oil pipe to be tested.

[0035] With this design, the oil pipe to be tested can be placed in the first groove 501, the friction force can be increased by the first rubber pad, and the oil pipe can be protected to avoid damage to the outer surface of the oil pipe.

[0036] like Figure 3 and Figure 4 As shown, the blocking detection assembly 6 includes a second electric push rod 601 fixedly connected to the left side plate 2, the telescopic end of the second electric push rod 601 passes through the left side plate 2 and is fixedly connected to the first support plate 602, and the first support plate 602 is fixedly installed with a first blocking nozzle 603 on one side close to the oil pipe to be detected.

[0037] A plurality of first guide rods 604 are fixedly connected to one side of the first support plate 602 close to the second electric push rod 601. The first guide rods 604 are arranged in parallel with the second electric push rod 601. The other end of the first guide rod 604 passes through the left side plate 2 and is fixedly connected to the first limit plate.

[0038] A pump body 605 is fixedly installed on the inner bottom wall of the box body 4 at a position close to the low liquid level, and the output end of the pump body 605 is connected to the first plugging nozzle 603 through a pipeline 606.

[0039] In this embodiment, the box body 4 is injected with detection liquid, and the pump body 605 is used to suck the detection liquid in the box body 4 and transport it to the first sealing nozzle 603 through the pipeline 606.

[0040] A controller 607 is installed on the left side of the bottom plate 1 , and a pressure gauge 608 is installed on the controller 607 . The detection end of the pressure gauge 608 is connected to the first plugging nozzle 603 .

[0041] In this design, the telescopic end of the second electric push rod 601 extends, driving the first support plate 602 and the first sealing nozzle 603 to move to the right, and the left end of the oil pipe to be tested can be sealed through the first sealing nozzle 603. When testing, the pump body 605 is used to suck the test liquid in the box body 4 and transport it to the oil pipe to be tested through the pipeline 606 and the first sealing nozzle 603.

[0042] like Figure 2 , Figure 4 and Figure 6 As shown, the sealing and exhaust assembly 7 includes a third electric push rod 701 fixedly connected to the right side plate 3, the output end of the third electric push rod 701 passes through the right side plate 3 and is fixedly connected to a second support plate 702, and a second sealing nozzle 703 is fixedly installed on the side of the second support plate 702 close to the oil pipe to be tested.

[0043] In this embodiment, a central through hole is opened in the middle of the second sealing nozzle 703 , and the central through hole passes through two side surfaces of the second sealing nozzle 703 .

[0044] A plurality of second guide rods 704 are fixedly connected to one side of the second support plate 702 close to the third electric push rod 701. The second guide rods 704 are arranged in parallel with the third electric push rod 701. The other end of the second guide rod 704 passes through the right side plate 3 and is fixedly connected to a second limit plate. The second guide rod 704 is slidably connected to the right side plate 3.

[0045] A cavity 705 communicating with the second sealing nozzle 703 is formed inside the second support plate 702 , and an exhaust assembly 706 is installed in the cavity 705 .

[0046] With such a design, the extension of the telescopic end of the third electric push rod 701 drives the second support plate 702 and the second sealing nozzle 703 to move leftward, and the second sealing nozzle 703 is used to seal the right end of the oil pipe.

[0047] like Figure 6 and Figure 7 As shown, the exhaust assembly 706 includes a through hole 7061 opened on the second support plate 702 , a U-shaped tube 7062 is fixedly connected to the through hole 7061 , and the other end of the U-shaped tube 7062 is arranged above the box body 4 .

[0048] Two sliding rods 7063 are fixedly connected to the inner top wall of the cavity 705 near the through hole 7061 , the bottom ends of the sliding rods 7063 are fixedly connected to the limiting blocks 7064 , and the sliding rods 7063 are slidably sleeved with lightweight sealing blocks 7065 corresponding to the through holes 7061 .

[0049] With such a design, when the oil pipe to be inspected is inspected, the air in the oil pipe enters the cavity 705 in the second support plate 702 through the second sealing nozzle 703, and is then discharged from the through hole 7061. When the air in the oil pipe is completely discharged, liquid enters the cavity 705. At this time, the lightweight sealing block 7065 is affected by the buoyancy and moves upward along the slide rod 7063 until the through hole 7061 is blocked. At this time, the left and right sides of the oil pipe are in a closed state.

[0050] In this embodiment, the first sealing nozzle 603 and the second sealing nozzle 703 are both of a conical structure. Such a design can better seal the end of the oil pipe and is convenient to use.

[0051] like Figure 1 and Figure 2As shown, in this embodiment, the left and right sides of the lower surface of the top plate 8 are fixedly connected with mounting plates 801, the sides away from the left side plate 2 and the right side plate 3 are fixedly connected with two guide rails 802, and one side of the mounting plate 801 is installed with two sliders 803, and the sliders 803 are slidably connected with the corresponding guide rails 802.

[0052] With this design, the cooperation between the guide rail 802 and the slider 803 can make the mounting plate 801 more stable when sliding up and down, avoid the phenomenon of tilting and getting stuck, and improve the use effect.

[0053] like Figure 1 and Figure 5 As shown, the main clamping seat 10 is in a U-shaped structure, and a clamping block 1001 is fixedly connected to the lower surface of the main clamping seat 10. A second groove 1002 is opened on the lower surface of the clamping block 1001, and a second rubber pad is fixedly connected to the inner wall of the second groove 1002; the inner surface shape of the second rubber pad matches the outer surface shape of the oil pipe to be tested.

[0054] With this design, the telescopic end of the first electric push rod 9 can shrink to drive the top plate 8 and the main clamping seat 10 to move downward until the main clamping seat 10 and the main supporting base 5 cooperate to clamp and fix the end of the oil pipe to be tested. At this time, the end of the oil pipe is located in the first groove 501 and the second groove 1002, which is convenient for use.

[0055] like Figure 3 and Figure 4 As shown, an auxiliary support base 12 is arranged between the two main support bases 5 , and the auxiliary support base 12 has the same structure as the main support base 5 .

[0056] An auxiliary clamping seat 13 is disposed between the two main clamping seats 10 , and the auxiliary clamping seat 13 has the same structure as the main clamping seat 10 .

[0057] With this design, the middle part of the oil pipe to be tested can be clamped and fixed through the cooperation of the auxiliary support base 12 and the auxiliary clamping base 13, so as to avoid excessive force on the two ends of the oil pipe to be tested and improve the use effect.

[0058] like Figure 2 and Figure 3 As shown, the striking assembly 11 includes a rotating shaft 1102 arranged between two mounting plates 801, and both ends of the rotating shaft 1102 are rotatably connected to the corresponding mounting plates 801 respectively, wherein a motor 1101 is fixedly mounted on any one of the mounting plates 801, and a power output end of the motor 1101 is transmission-connected to one end of the rotating shaft 1102, and a plurality of rubber rods 1103 are fixedly connected to the outer surface of the rotating shaft 1102.

[0059] With such a design, the motor 1101 drives the rotating shaft 1102 and the rubber rod 1103 to rotate. The rubber rod 1103 can knock the oil pipe to be tested during the rotation, which can not only simulate the vibration environment of the oil pipe to be tested, but also the upper surface of the bottom plate 1 gradually increases toward the right side, so that the right end of the oil pipe to be tested that has been clamped and positioned is higher, so that the air in the oil pipe can be quickly discharged, thereby improving the use effect.

[0060] When in use, first inject the detection liquid into the box body 4, then the telescopic end of the first electric push rod 9 extends to drive the top plate 8 and the main clamping seat 10 to move upward, so that the main clamping seat 10 is separated from the main support base 5, and then the ends of the oil pipe to be tested are placed in the first grooves 501 on the main support base 5 respectively.

[0061] Then start the first electric push rod 9 to shrink its telescopic end, driving the top plate 8 and the main clamping seat 10 to move downward until the main clamping seat 10 and the main supporting base 5 cooperate to fix the end of the oil pipe to be inspected. Then the telescopic end of the second electric push rod 601 extends, driving the first support plate 602 and the first sealing nozzle 603 to move to the right, and the left end of the oil pipe to be inspected is sealed through the first sealing nozzle 603.

[0062] Then the third electric push rod 701 extends to drive the second support plate 702 and the second sealing nozzle 703 to move leftward, and the right side of the oil pipe is sealed through the second sealing nozzle 703.

[0063] Then start the pump body 605 to suck the test liquid in the box body 4 and transport it to the oil pipe through the pipeline 606 and the first sealing nozzle 603. At this time, the air in the oil pipe enters the cavity 705 in the second support plate 702 through the second sealing nozzle 703, and then is discharged from the through hole 7061 for easy use.

[0064] The starting motor 1101 drives the rotating shaft 1102 and the rubber rod 1103 to rotate. The rubber rod 1103 is used to knock the oil pipe during the rotation process to simulate the vibration environment of the oil pipe. The upper surface of the bottom plate 1 gradually increases toward the right side, so that the right end of the oil pipe to be tested that has been clamped and positioned is higher, so that the air in the oil pipe can be quickly discharged into the cavity 705, thereby improving the use effect.

[0065] When the air in the oil pipe is completely discharged, liquid enters the cavity 705. At this time, the lightweight sealing block 7065 will move upward along the slide rod 7063 due to the buoyancy until the through hole 7061 is blocked. At this time, the left and right sides of the oil pipe are in a closed state. The oil pipe is pressurized by continuous pressurization of the pump body 605 to observe whether there is liquid overflow from the connection between the pressure gauge 608 and the oil pipe, and then determine whether the performance of the oil pipe is qualified.

[0066] After the test is completed, the tested oil pipe is removed, and the liquid in the cavity 705 will flow back into the box body 4 from the second sealing nozzle 703, and then the oil pipe to be tested is replaced to continue the next test operation.

[0067] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
