Description

Technical Field

[0001] The utility model belongs to the technical field of pressure vessel processing, and particularly relates to a pressure testing mechanism for pressure vessels. Background Technique

[0002] In the process of producing pressure vessels, it is necessary to conduct pressure testing on the pressure vessels. For the existing pressure testing mechanisms for pressure vessels, although they can meet the basic requirements for pressure testing of pressure vessels, since only one pressure vessel can be tested at a time, after the pressure testing of one pressure vessel is completed, it is often necessary to wait until the tested pressure vessel is removed from the testing table and a new pressure vessel is placed on the testing table before the testing structure can be used to test the new pressure vessel. Users need to spend a lot of time specifically on loading and unloading the pressure vessels, so it will seriously affect the efficiency of pressure testing multiple pressure vessels and cannot fully meet people's usage requirements.

[0003] For example, the utility model with the publication number CN 208297105 U discloses a pressure testing device for pressure vessels. In the technical solution of this patent, since only one pressure vessel can be fixed on the base at a time, after the testing of one pressure vessel is completed, it is necessary to wait for the unloading and reloading of the pressure vessel to continue the pressure testing of the pressure vessel, and the loading and unloading of other pressure vessels cannot be carried out during the testing time. Therefore, there is a problem that it will seriously affect the efficiency of testing multiple pressure vessels. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies of the prior art, the utility model provides a pressure testing mechanism for pressure vessels, which can not only meet the basic requirements for pressure testing of pressure vessels, but also enable users to unload and load other pressure vessels while testing one pressure vessel, without the need for users to specifically pause the testing structure for a long time to wait for the unloading and loading of the pressure vessels, thereby significantly improving the efficiency of testing multiple pressure vessels.

[0005] To solve the above technical problems, the technical solution adopted by the present utility model is as follows: A pressure vessel pressure test mechanism includes a test bench. Support legs are provided at the bottom of the test bench. Along the front-rear direction, a plurality of placement benches are detachably arranged on the top of the test bench. A plurality of placement grooves for placing pressure vessels to be tested are provided on the plurality of placement benches. Vertical rods located outside the placement benches are respectively provided at the left corner of the top of the processing bench. A top plate is commonly provided at the tops of the four vertical rods. First linear sliders running along the front-rear direction are respectively provided at the left and right side ends of the bottom of the top plate. A second linear slider running along the left-right direction is commonly provided at the bottoms of the sliders of the two first linear sliders. A U-shaped fixed frame with an open right end is provided at the bottom of the slider of the second linear slider. A telescopic push rod is vertically provided at the bottom of the fixed frame. An air charging pipe is provided at the lower end of the output shaft of the telescopic push rod. A threaded joint that is screwed and fixed to the air inlet of the pressure vessel is provided at the lower end of the air charging pipe in a screwed manner. An air pump is provided on the inner wall at the bottom end of the fixed frame. A gas guide hose is provided between the air outlet end of the air pump and the air inlet pipe. A gas flow meter is provided on the air inlet pipe.

[0006] As a further improvement of the present utility model, both placement benches are snap-fitted and fixed to the detection bench, and snap-fitting grooves adapted to the test bench are provided on the detection bench.

[0007] As a further improvement of the present utility model, handles are provided on the tops of both placement benches.

[0008] As a further improvement of the present utility model, extension plates are further provided at the bottom side ends of the support legs, and anchor bolts for connecting to the ground are further provided on the extension plates.

[0011] As a further improvement of the present utility model, anti-slip sleeves are further provided on the handles; discharge holes respectively adapted to the plurality of placement grooves are further provided at the bottoms of both placement benches.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] First, the user can first place multiple pressure vessels to be detected into multiple placement grooves of a placement table. Then, the placement table and the multiple pressure vessels can be placed on the detection table. After that, the telescopic push rod can be used to move the air charging pipe and the threaded joint downward, and the threaded joint can be screwed and fixed to the air inlet of a pressure vessel. Subsequently, the valve on the air inlet of the pressure vessel can be opened. Then, the air pump can be started, and gas can be filled into the pressure vessel through the air guiding hose, the air charging pipe, and the air inlet. When it is found through the gas flowmeter that a sufficient amount of gas has been filled, the air pump can be paused, and the threaded joint can be separated from the air inlet of the pressure vessel. Then, the pressure-bearing condition of the pressure vessel can be checked. The expansion data of the pressure vessel can also be collected through an existing expansion detector, and the pressure resistance of the pressure vessel can be analyzed by a computer. Then, the vertical position of the air charging pipe and the threaded joint can be adjusted through the telescopic push rod, and the horizontal position of the air charging pipe and the threaded joint in the front-rear direction can be adjusted through the first linear slide table, so as to complete the pressure test detection of multiple pressure vessels on one placement table. During the detection process, the user can simultaneously place multiple pressure vessels to be detected into multiple placement grooves of another placement table. Then, the other placement table and the multiple pressure vessels can be placed on the detection table. After completing the detection of the pressure vessels on one detection table, the air charging pipe and the threaded joint can be moved above the other placement table and the multiple pressure vessels through the second linear slide table. Then, the pressure test detection of the multiple pressure vessels can be continued. At the same time, the previous placement table and the pressure vessels can be taken away from the test table together, and the pressure vessels on the placement table can be replaced. Then, the placement table and the multiple pressure vessels can be placed on the detection table again. Therefore, the technical solution of the present application does not need to specifically pause the pressure test of the pressure vessels for a long time, and can significantly improve the pressure test detection efficiency of multiple pressure vessels by quickly feeding and loading multiple pressure vessels while detecting.

[0014] Second, through the clamping groove, the user can easily achieve or release the flexible fixation of the placement table and the processing table. Through the extension plate and the anchor bolts, the device can be effectively prevented from easily shifting and tipping over during operation.

[0015] Third, through the placement guiding strip, the user can easily place multiple pressure vessels to be pressure-tested in the placement grooves in the correct posture, so that the user can then easily perform the operation of filling the pressure vessels with gas, thus facilitating the pressure test detection of the pressure vessels. Through the strengthening rod, the firmness between the vertical rod and the top plate can be enhanced.

[0016] Fourthly, through the handle, the placing table can be conveniently moved, and the clamping and fixing of the placing table and the processing table can be conveniently achieved or released. Through the anti-slip sleeve, the handle can be conveniently operated; through the discharge hole, dust and other sundries entering the placing groove can be conveniently cleaned up.

[0023] In order to better understand the present utility model, the content of the present utility model will be further clearly elaborated below in conjunction with embodiments, but the protection scope of the present utility model is not limited to the following embodiments. In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.

[0024] Such as Figure 1 、 2, as shown in Figures 3, a pressure vessel pressure test mechanism includes a test bench 101. Support legs 102 are provided at the bottom of the test bench 101. A plurality of placement platforms 103 are detachably arranged on the top of the test bench 101 in the front-rear direction.

Vertical rods 105 located outside the placement platforms 103 are respectively provided at the left corner of the top of the processing bench. A top plate 106 is commonly provided at the tops of the four vertical rods 105. First linear sliders 107 running in the front-rear direction are respectively provided at the left and right side ends of the bottom of the top plate 106. A second linear slider 108 running in the left-right direction is commonly provided at the bottom of the sliders of the two first linear sliders 107. A U-shaped fixed frame 109 with an open right end is provided at the bottom of the slider of the second linear slider 108. A telescopic push rod 110 is vertically provided at the bottom of the fixed frame 109. An air charging pipe 111 is provided at the lower end of the output shaft of the telescopic push rod 110. A threaded joint 112 that is screwed and fixed to the air inlet of the pressure vessel is screwed at the lower end of the air charging pipe 111. An air pump 113 is provided on the inner wall of the bottom end of the fixed frame 109. A gas guide hose 114 is provided between the air outlet end of the air pump 113 and the air inlet pipe. A gas flow meter 115 is provided on the air inlet pipe.

[0025] As Figure 1 , 2 shown, both of the two placement platforms 103 are snap-fitted and fixed to the detection bench.

Through the snap-fitting groove 116, the user can conveniently achieve or release the flexible fixation of the placement platform 103 and the processing bench.

[0026] The user can first place multiple pressure vessels to be detected into multiple placement grooves 104 of a placement table 103. Then, the placement table 103 and the multiple pressure vessels can be placed on the detection table. After that, the telescopic push rod 110 can be used to move the gas filling pipe 111 and the threaded joint 112 downward, and make the threaded joint 112 be screwed and fixed with the air inlet of a pressure vessel. Subsequently, the valve on the air inlet of the pressure vessel can be opened. Then, the air pump 113 can be started, and gas can be filled into the pressure vessel through the air guide hose 114, the gas filling pipe 111 and the air inlet.

After completing the detection of the pressure vessels on one detection table, the second linear slide table 108 can be used to move the gas filling pipe 111 and the threaded joint 112 above the other placement table 103 and the multiple pressure vessels. Then, the pressure test detection of the multiple pressure vessels can be continued. At the same time, the previous placement table 103 and the pressure vessels can be taken away from the test table 101 together, and the pressure vessels on the placement table 103 can be replaced. Then, the placement table 103 and the multiple pressure vessels can be placed on the detection table together again. Therefore, the technical solution of the present application does not need to specifically pause the pressure test of the pressure vessels for a long time, and can significantly improve the pressure test detection efficiency of multiple pressure vessels by quickly feeding and unloading multiple pressure vessels while detecting.

Through the placement guiding strips 201, the user can conveniently place a plurality of pressure vessels to be pressure-tested in the placement grooves 104 in the correct posture, so that the user can subsequently conveniently inflate the pressure vessels, thereby conveniently performing pressure testing on the pressure vessels.

[0031] According to another embodiment of the present invention, as Figure 4 shown, a reinforcing rod 202 is further provided between the vertical rod 105 and the top plate 106. Through the reinforcing rod 202, the firmness between the vertical rod 105 and the top plate 106 can be enhanced.
