Description

Technical Field

[0001] This invention relates to the field of flaw detection equipment technology, specifically a portable X-ray flaw detection device. Background Technology

[0002] X-ray flaw detection equipment is a core method of industrial non-destructive testing, widely used for detecting internal defects in steel structure welds, pressure vessels, pipelines, and engineering machinery components. It can accurately identify internal quality defects such as cracks, pores, and inclusions. X-rays are electromagnetic waves with short wavelengths and strong penetrating power, easily penetrating metal materials such as steel and aluminum alloys. When X-rays pass through a workpiece, the density is uniform in intact areas, and the attenuation of the rays is consistent. However, in areas with defects such as pores, cracks, and inclusions, the density differs from that of normal areas, resulting in significant differences in the attenuation of the rays.

[0003] However, traditional X-ray flaw detection equipment has the following drawbacks:

[0004] For a long time, the image of traditional X-ray flaw detection equipment as "big, clumsy and crude" has become a huge obstacle to field pipeline laying, high-altitude bridge inspection and complex construction site operations. The equipment weighs tens of kilograms, has a strict dependence on a stable power supply and a fragile precision structure, which often makes it difficult for inspection personnel to cope with extreme working conditions such as high altitude and field. Summary of the Invention

[0005] The purpose of this invention is to provide a portable X-ray flaw detection device to solve the long-standing problem mentioned in the background art: the traditional X-ray flaw detection equipment has long been characterized by its bulky and crude appearance, which has become a huge obstacle to field pipeline laying, high-altitude bridge inspection, and complex construction site operations. The equipment's weight of tens of kilograms, its strict dependence on a stable power supply, and its fragile precision structure often make it difficult for inspection personnel to perform their tasks in extreme working conditions such as high altitudes and field operations.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a portable X-ray flaw detection device, including a fixed base,

[0007] A push rod is fixedly installed on one side of the top of the fixed base, and four locking posts arranged in a rectangle are fixedly installed on the other side of the top of the fixed base. A lifting mechanism is engaged between the four locking posts.

[0008] The lifting mechanism includes two height shells and a heat-conducting plate. The top of each of the two height shells is slidably connected to a height plate, and the top of each of the two height plates is fixedly connected to both sides of the bottom of the heat-conducting plate.

[0009] An aluminum shell is fixedly installed at the top of the heat-conducting plate, and an X-ray generator is fixedly installed inside the aluminum shell. A cooling mechanism is fixedly installed at the bottom of the heat-conducting plate, and a control panel is fixedly installed on one side of one of the shells.

[0010] Furthermore, the cooling mechanism includes a condensate tank, a pump body, and a cooling housing. The outlet of the pump body is fixedly connected to a delivery hose. One end of the delivery hose is fixedly connected to the side of the cooling housing facing the pump body. The other side of the bottom of the cooling housing is fixedly connected to a return hose. One side of the condensate tank is fixedly connected to an extraction pipe. One end of the return hose and one end of the extraction pipe are both fixedly connected to the inlet of the pump body.

[0011] Furthermore, a connecting platform is fixedly installed between the two height shells. The bottom end of the condensate tank and the bottom end of the pump body are both fixedly connected to the connecting platform. The pump body draws condensate from the condensate tank through the extraction pipe. The extracted condensate is transported to the cooling housing through the delivery hose. The cooling housing uses the condensate to transfer heat to the heat conduction plate for heat dissipation and cooling. Excess condensate is transported back to the cooling housing through the return hose and the pump body.

[0012] Furthermore, a temperature sensor extending into the cooling housing is fixedly installed on the surface of the cooling housing, and the temperature sensor senses the cooling temperature inside the cooling mechanism in real time.

[0013] Furthermore, the top of the cooling housing is fixedly connected to the middle of the bottom of the heat-conducting plate. Several heat dissipation strips are fixedly installed on the surface of the cooling housing. The cooling mechanism is mounted on the heat-conducting plate through the cooling housing. The cooling housing is in close contact with the heat-conducting plate to transfer heat to the heat-conducting plate. The heat dissipation strips increase the heat dissipation area of ​​the cooling housing and improve the cooling efficiency of the cooling mechanism.

[0014] Furthermore, cylinder mounting bases are fixedly installed on opposite sides of the two height shells, and lifting cylinders are fixedly installed on the top of the two cylinder mounting bases. The movable ends of the two lifting cylinders are fixedly connected to the side of the heat-conducting plate facing each other. The lifting cylinders perform telescopic movements and push the heat-conducting plate from the bottom to adjust the operating height of the X-ray generator.

[0015] Furthermore, slots are provided on both sides of the bottom of the two height shells, and the four slots are respectively set to correspond to the four locking posts. The lifting mechanism is inserted into the locking posts through the slots to complete the assembly of the lifting mechanism and the fixed base.

[0016] Furthermore, a handle is fixedly installed on the heat-conducting plate on the outside of the aluminum shell, allowing the user to carry and move the flaw detection device.

[0017] Furthermore, each of the four corners of the fixed base is fixedly equipped with a movable wheel. When the user pushes the push rod, the movable wheel comes into contact with the ground and generates friction, which facilitates the user to move and transport the flaw detection device.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] By setting up a push rod, movable wheels, and a fixed base, the user assembles the lifting mechanism onto the fixed base using the locking pins and slots. This allows the X-ray generator to be assembled onto the fixed base. Then, the user pushes the push rod, and the movable wheels rotate due to friction with the ground, making it easy for the user to carry and transport the flaw detection device.

[0026] Please see Figure 1-4 The present invention provides a portable X-ray flaw detection device, including a fixed base 1.

[0028] The lifting mechanism 5 includes two height shells 51 and a heat-conducting plate 53. The top of each of the two height shells 51 is slidably connected to a height plate 52, and the top of each of the two height plates 52 is fixedly connected to the two sides of the bottom of the heat-conducting plate 53 respectively.

[0029] An aluminum shell 8 is fixedly installed on the top of the heat-conducting plate 53. An X-ray generator 10 is fixedly installed inside the aluminum shell 8. A cooling mechanism 7 is fixedly installed on the bottom of the heat-conducting plate 53. A control panel 6 is fixedly installed on one side of one of the height shells 51.

[0030] The cooling mechanism 7 includes a condensate tank 71, a pump body 72, and a cooling housing 74. The outlet of the pump body 72 is fixedly connected to a delivery hose 73. One end of the delivery hose 73 is fixedly connected to the side of the cooling housing 74 facing the pump body 74. The other side of the bottom of the cooling housing 74 is fixedly connected to a return hose 76. One side of the condensate tank 71 is fixedly connected to an extraction pipe 77. One end of the return hose 76 and one end of the extraction pipe 77 are both fixedly connected to the inlet of the pump body 72.

[0031] A connecting platform 56 is fixedly installed between the two height shells 51, and the bottom ends of the condensate tank 71 and the pump body 72 are both fixedly connected to the connecting platform 56.

[0032] In use, the pump body 72 draws condensate from the condensate tank 71 through the extraction pipe 77. The drawn condensate is then transported to the cooling housing 74 through the delivery hose 73. The cooling housing 74 uses the condensate to transfer heat to the heat conduction plate 53 for cooling. Excess condensate is then transported back to the cooling housing 74 through the return hose 76 via the pump body 72.

[0033] A temperature sensor 78 extending into the interior is fixedly mounted on the surface of the cooling housing 74.

[0034] During use, the temperature sensor 78 senses the cooling temperature inside the cooling mechanism 7 in real time.

[0035] The top of the cooling housing 74 is fixedly connected to the middle of the bottom of the heat-conducting plate 53, and several heat dissipation strips 75 are fixedly installed on the surface of the cooling housing 74.

[0036] In use, the cooling mechanism 7 is mounted on the heat-conducting plate 53 through the cooling housing 74. The cooling housing 74 is in close contact with the heat-conducting plate 53 to transfer heat to the heat-conducting plate 53. The heat dissipation strip 75 increases the heat dissipation area of ​​the cooling housing 74 and improves the cooling efficiency of the cooling mechanism 7.

[0037] A cylinder mounting base 55 is fixedly installed on the opposite side of each of the two height shells 51. A lifting cylinder 54 is fixedly installed on the top of each of the two cylinder mounting bases 55. The movable ends of the two lifting cylinders 54 are fixedly connected to the side of the heat-conducting plate 53 that is directly opposite to it.

[0038] In use, the lifting cylinder 54 extends and retracts, pushing the heat-conducting plate 53 from the bottom to adjust the operating height of the X-ray generator 10.

[0039] Both sides of the bottom of the two height shells 51 are provided with slots 11, and the four slots 11 are respectively set to correspond to the four locking posts 4.

[0040] In use, the lifting mechanism 5 is inserted into the locking post 4 through the locking slot 11, thus completing the assembly of the lifting mechanism 5 and the fixed base 1.

[0041] A handle 9 is fixedly installed on the heat-conducting plate 53, located on the outside of the aluminum shell 8.

[0042] When in use, the user carries and moves the flaw detection device by using handle 9.

[0043] The four corners of the bottom of the fixed base 1 are all fixedly installed with casters 2.

[0044] When in use, the user pushes the push rod 3, causing the moving wheel 2 to come into contact with the ground and generate friction, making it easier for the user to move and transport the flaw detection device.

[0045] In this embodiment, the X-ray generator 10 is assembled from top to bottom as follows: an upper end ring, a cable connector, an alarm, a high-voltage transformer, an X-ray tube, an aluminum shell 8 (isolation structure), a heat sink, a cooling fan, and a temperature relay. The structure is compact and highly integrated. The aluminum shell 8 uses a fully sealed installation method, effectively preventing X-ray leakage and reducing the risk of radiation exposure during operation. Dual-point temperature relays are respectively arranged on the upper inner wall of the aluminum tube and the side of the heat sink, providing comprehensive monitoring of the machine's operating temperature and real-time linkage with the alarm to achieve over-temperature warning. The lifting cylinder 54 performs telescopic movement, pushing the heat-conducting plate 53 from the bottom to adjust the operating height of the X-ray generator 10. The lifting mechanism 5 engages with the locking post 4 through the slot 11, completing the lifting operation. The assembly of component 5 and fixed base 1 involves the user pushing the push rod 3, causing the moving wheels 2 to contact the ground and generate friction, facilitating the user's transfer and transportation of the flaw detection device. During operation, the generator and controller are quickly connected and assembled via a dedicated cable. The operator sets the flaw detection parameters and starts the detection operation through the control panel 6. The high-voltage transformer provides a stable working voltage to the X-ray tube, generating standard X-rays to complete the workpiece penetration flaw detection. During operation, the temperature relay monitors the machine body temperature in real time, and triggers the alarm immediately when the temperature exceeds the limit to avoid high-temperature failures. Flaw detection data is uploaded to the controller in real time and can be stored locally, quickly exported via USB, or wirelessly transmitted remotely, completing the entire intelligent flaw detection operation. After the operation is completed, the equipment can be quickly disassembled for easy storage and transportation.
