AI Technical Summary
[0002]金属管道具有较高的强度和耐腐蚀性,适用于高压与特殊材质的输送,尤其是石油、天然气的输送对管道的焊接必须严格要求,才能保证输送过程中的安全,因此对管道焊口的检测至关重要,而X射线探伤以其独特的方式可以检测出焊缝内部的缺陷,如裂纹、缩孔、气孔、夹渣、未溶合、未焊透等,对于管道的焊缝来说它本身是一个圆周型,因此不可能一次成像,而是要沿周向分段成像,尤其是一些大口径的管道,一个焊口要分10段-20段进行成像,每一段的成像时间与管壁的厚度有关,对于管壁较厚的管道检测一个焊口成像时间要耗费30分钟-60分钟,甚至更长,这样就要求X射线光机不间断地曝光,X射线光机工作时间较长,虽然X射线光机自身带有冷却风扇进行对机头进行物理降温,但在实际使用过程中也会导致X射线光机温度过高,出现超温停光情况,尤其是在高温天气使用X射线光机检测的情况下,X射线光机超温停光后如果在较短的冷却时间内重新曝光,曝光后机头温度会在短时间急剧上升,一般2分钟-3分钟内又会重新超温而停光,除非让X射线光机在自身风扇排热的情况下冷却很长的时间再重新曝光,这样会严重影响焊口检测的时间
[0019] This equipment can improve the cooling capacity of the X-ray machine head, slow down the rate of temperature rise of the X-ray machine head, and keep the temperature of the X-ray machine head within the normal operating temperature range for a longer period of time, ensuring the normal exposure time of the X-ray machine head and enabling the detection work to proceed smoothly.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of X-ray flaw detection technology, and in particular to a cooling device for an X-ray optical machine head. Background Technology
[0002] Metal pipes possess high strength and corrosion resistance, making them suitable for transporting high-pressure and special materials. Especially for the transportation of oil and natural gas, the welding of pipelines must meet stringent requirements to ensure safety during transport. Therefore, the inspection of pipe welds is crucial. X-ray inspection, with its unique method, can detect internal defects in welds, such as cracks, shrinkage cavities, porosity, slag inclusions, incomplete fusion, and incomplete penetration. Since a pipe weld is circumferential, it cannot be imaged in a single pass; instead, it must be imaged in segments along the circumference. This is especially true for large-diameter pipes, where a single weld may require imaging in 10-20 segments. The imaging time for each segment depends on the pipe wall thickness. For pipes with thicker walls, the imaging time for inspecting a single weld segment varies. It takes 30 to 60 minutes, or even longer, requiring the X-ray machine to expose continuously. Although the X-ray machine has its own cooling fan to physically cool the machine head, the actual use can still cause the X-ray machine to overheat and shut down, especially in hot weather. If the X-ray machine is restarted after overheating and shut down, the machine head temperature will rise sharply in a short time after exposure, and it will usually overheat and shut down again within 2 to 3 minutes. Unless the X-ray machine is allowed to cool down for a long time with its own fan to dissipate heat, it will seriously affect the weld inspection time. Utility Model Content

[0029] like Figures 1-8 The X-ray machine head cooling device shown is assembled on the outer periphery of the main body 11 of the X-ray machine head 1. The X-ray machine head cooling device includes a coolant storage tank 2, a sealing mechanism 4, a light-emitting side support block 7, a circumferential support block 8, and a clamping mechanism 3. The X-ray machine head 1 is operated by the operator holding the handle 14 during testing.
[0030] The cooling material storage tanks 2 are multiple and arranged in a circular array. Each cooling material storage tank 2 includes a tank body 21 with an injection port 22 at its outer end.

One side of the light-emitting side support block 7 has several first fixing holes 71, and the other side has two pairs of second fixing holes 72. One end face of the light-emitting side support block 7 has a first threaded hole 73. The contact surface between the light-emitting side support block 7 and the coolant storage tank 2 has several holes that slide and penetrate the trapezoidal column 23. A first trapezoidal groove 74 extends through one end of the light-emitting side support block 7. A pair of tensioning mechanisms 5 are connected between the two light-emitting side support blocks 7. The tensioning mechanism 5 includes a rubber tensioning rope 51, with hooks 54 at both ends of the rubber tensioning rope 51. The tensioning mechanism 5 also includes a V-shaped hook frame 52 mounted on one side of the light-emitting side support block 7 and used for hanging the hooks 54. Specifically, both ends of the V-shaped hook frame 52 are provided with screw hole plates. The screw hole plates are screwed to the second fixing hole 72 by a hook frame screw 53, so that the V-shaped hook frame 52 is fixed.
[0033] There are multiple circumferential support blocks 8, which are respectively assembled on the bottom surface of the cooling material storage tank 2 that is not assembled with the light-emitting side support block 7. Several third fixing holes 83 are opened on both sides of the circumferential support block 8. A second threaded hole 82 is opened on one end face of the circumferential support block 8. Several second trapezoidal grooves 81 that slide with the trapezoidal column 23 and penetrate one end of the circumferential support block 8 are opened on the contact surface between the circumferential support block 8 and the cooling material storage tank 2. Several connecting mechanisms 6 are assembled between each two adjacent circumferential support blocks 8, and between the circumferential support blocks 8 located at both ends of the circumference and the adjacent light-emitting side support block 7. The connecting mechanism 6 includes connecting bolts 61 that match the first fixing hole 71 and the third fixing hole 83. A connecting ring 62 is provided between two connecting bolts 61. Specifically, the head of the connecting bolt 61 has a ring opening, and the connecting ring 62 passes through the ring opening of the two connecting bolts 61.
[0034] There are multiple clamping mechanisms 3. Two of them are assembled between the light-emitting side support block 7 and the coolant storage tank 2 and are located outside the opening end of the first trapezoidal groove 74. The other clamping mechanisms 3 are assembled between the circumferential support block 8 and the coolant storage tank 2 and are located outside the opening end of the second trapezoidal groove 81. The clamping mechanism 3 includes a clamping screw 31. One end of the clamping screw 31 is provided with a threaded body 32 that matches both the first threaded hole 73 and the second threaded hole 82. A spring 33 is provided on the outer periphery of the clamping screw 31. The clamping mechanism 3 also includes a C-shaped pressure plate 34. The lower end of the pressure plate 34 is provided with a through plate. The side of the through plate is provided with an insertion hole 35. The clamping screw 31 passes through the insertion hole 35. One side of the pressure plate 34 is provided with a protrusion 36 that matches the recess 24. The upper end of the pressure plate 34 is provided with an adjusting handle 37.
[0035] The cooling material storage tank 2, the light-emitting side support block 7, and the circumferential support block 8 are all made of metal to accelerate heat conduction.
[0036] Work style:
[0037] When the X-ray machine head 1 is in operation and exposure, it generates heat. As the exposure time increases, this heat causes the temperature of the X-ray machine head 1 to rise sharply. Although the X-ray machine head 1 has a built-in cooling fan that exhausts air through the air outlet 12, it has been found in actual testing that the fan's heat dissipation capacity is insufficient to maintain the head temperature at a normal operating level. Therefore, the cooling device described in this application is installed. The specific installation method is as follows:
[0038] The annular assembly formed by the two light-emitting side support blocks 7 and the circumferential support blocks 8 connected by the linking mechanism 6 is fitted onto the outer periphery of the main body 11, and its position is adjusted so that the light-emitting port 13 is located inside the notch of the annular assembly. Then, the entire cooling device is fixed by hanging it on the two V-shaped hook frames 52 through the hooks 54 at both ends of each rubber tension rope 51.
[0039] Then, each coolant storage tank 2 is assembled onto the light-emitting side support block 7 or the circumferential support block 8. Specifically, the trapezoidal column 23 is pushed in from the opening end of the first trapezoidal groove 74 or the opening end of the second trapezoidal groove 81 until one end face of the coolant storage tank 2 is on the same plane as one end face of the light-emitting side support block 7 or one end face of the circumferential support block 8. Then, the clamping mechanism 3 is used to clamp the connection between the coolant storage tank 2 and the light-emitting side support block 7, or to clamp the connection between the coolant storage tank 2 and the circumferential support block 8. Specifically, the protrusion 36 is pressed into the recess 24, and then the clamping screw 31 is rotated so that the threaded body 32 is screwed into the first threaded hole 73 or the second threaded hole 82.
[0040] Next, coolant is placed in coolant storage tank 2. Specifically, water below 5°C, ice, or dry ice can be used. Then, each coolant storage tank 2 is sealed using sealing mechanism 4.
[0041] During operation, the heat generated by the X-ray machine head 1 is conducted to the light-emitting side support block 7 and the circumferential support block 8. When the temperature of the light-emitting side support block 7 and the circumferential support block 8 tends to rise, the heat is transferred to the coolant storage tank 2 and the coolant loaded inside. Since the coolant can absorb a large amount of heat, the rate of temperature rise of the X-ray machine head 1 is slowed down. At the same time, the airflow generated by the fan of the X-ray machine head 1 will also carry away some of the heat from the coolant storage tank 2. In this way, the whole device can ensure that the temperature rise of the X-ray machine head 1 is slowed down.
[0042] The above are only some of the embodiments listed in this application and are not intended to limit this application.
