Description

Technical Field

[0001] This utility model relates to the field of pressure vessel pressure resistance testing technology, and in particular to a pressure resistance testing device for a type of mobile pressure vessel. Background Technology

[0002] Pressure vessel pressure resistance testing involves applying a test pressure higher than the design pressure to verify the strength, sealing performance, and presence of defects (such as cracks, deformation, etc.) of the vessel, preventing leaks or explosions during use. The testing process requires the use of appropriate testing equipment.

[0003] Existing testing devices require casters for movement during use. When performing pressure tests on pressure vessels, wobbling is not allowed. Although the casters can be locked, accidental contact with the device can still cause wobbling, affecting the accuracy of the pressure test results. Therefore, this invention proposes a pressure testing device for mobile pressure vessels. Utility Model Content

[0006] The support assembly includes a support leg with an anti-slip protrusion at the bottom. The main body of the device has an adjustment groove and a sliding groove inside. A slider is provided on the outside of the support leg. A threaded rod and a drive motor are provided inside the adjustment groove. The support leg has a threaded groove inside. A driven gear is provided on the outside of the threaded rod. A drive gear is provided at the output end of the drive motor. An electric push rod is provided inside the main body of the device. A positioning pin is provided at the output end of the electric push rod. A positioning groove is provided on the outside of the support leg.

[0007] As a further technical solution of this utility model, four sets of universal wheels are installed at the bottom of the main body of the device near the corner. The number of universal wheels is four and they are arranged in an array. The number of support components is four and they are arranged in an array.

[0008] As a further technical solution of this utility model, the control cabinet and the winding roller are movably connected, the connector is connected to the pressure reducing valve, a clamping cylinder is installed on one side of the clamping block, and the clamping block is made of rubber.

[0009] As a further technical solution of this utility model, control buttons and a display screen are installed on the outside of the control panel, and a control circuit board and a battery are installed inside the control panel. The handle and the main body of the device are connected by bolts.

[0010] As a further technical solution of this utility model, the support leg and the anti-slip protrusion are fixedly connected, the adjustment groove is adapted to the support leg, the slider is adapted to the slide groove, and a bearing seat is provided at the connection between the threaded rod and the adjustment groove.

[0011] As a further technical solution of this utility model, the threaded groove and the threaded rod are adapted to each other, the driven gear and the driving gear are meshed, the output end of the electric push rod is fixedly connected to the positioning pin, and the positioning pin is adapted to the positioning groove.

[0012] This invention provides a pressure testing device for a type of mobile pressure vessel. Compared with the prior art, it has the following advantages:

[0013] This design discloses a pressure testing device for a mobile pressure vessel. A support assembly is installed at the bottom of the device body. When the device body requires stable support, four drive motors are simultaneously activated, engaging the drive and driven gears. This causes the threaded rod to rotate along the threaded groove, lowering the support leg along the adjustment groove. When the device body is lifted, the casters are removed from the ground. The output end of the corresponding electric push rod then drives the positioning pin to insert into the positioning groove, thus positioning the support leg and stabilizing the device body, preventing wobbling and ensuring the accuracy of the pressure test values.

[0022] The support component 3 includes a support leg 31, with an anti-slip protrusion 32 at the bottom. The main body 1 of the device has an adjustment groove 33 and a sliding groove 35 inside. The support leg 31 has a slider 34 on the outside. The adjustment groove 33 has a threaded rod 36 and a drive motor 39 inside. The support leg 31 has a threaded groove 37 inside.

The electric push rod 311 has a positioning pin 312 at its output end. The support leg 31 has a positioning groove 313 on its outside.

[0023] like Figure 1-4As shown, four sets of casters 2 are installed at the bottom of the main body 1 near the corner. The casters 2 are arranged in an array. The support components 3 are also arranged in an array. This facilitates the support of the main body 1. The control cabinet 4 is connected to the winding roller 6. The connector 7 is connected to the pressure reducing valve 5. A clamping cylinder is installed on one side of the clamping block 9. The clamping block 9 is made of rubber, which facilitates the clamping and fixing of the pressure vessel.

[0024] like Figure 1-2 As shown, control buttons and a display screen are installed on the outside of the control panel 10, and a control circuit board and a battery are installed inside the control panel 10. The handle 11 is connected to the main body 1 of the device by bolts, which facilitates the operation of the control device.
