[0002] Radiographic film inspection technology utilizes radiation to penetrate the workpiece, uses film as an imaging device to record the radiation intensity distribution after the radiation penetrates the workpiece, and displays the intensity distribution in the form of an image. By analyzing the image, the size, distribution and properties of defects and discontinuities in materials and their components can be intuitively displayed. It has been widely used in the industrial field.

[0003] When performing X-ray inspection on medium and large diameter pipelines, depending on the accessibility of the X-ray machine, you can choose to perform the inspection by using the X-ray machine outside the pipe or inside the pipe. When performing the inspection outside the pipe, the X-rays must penetrate two layers of wall thickness, resulting in a long inspection time. At the same time, the length of the weld that can be inspected each time is limited, so multiple inspections are required to complete the inspection of a weld, and the inspection efficiency is low. When performing the inspection inside the pipe, although the entire circle of the weld can be inspected at one time to achieve high inspection efficiency, this method requires the X-ray machine's radiation source to be placed at the center of the pipe, and the X-ray machine's radiation source must be aligned with the weld to ensure that the radiation area covers the weld.

[0004] In order to solve the problem that it is difficult to accurately send the X-ray machine to a position that cannot be reached by humans and ensure that the X-ray machine is at the center of the pipeline when irradiating the medium and large diameter pipeline inside the X-ray tube, a pipeline X-ray detection auxiliary device is proposed.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 In an embodiment of the utility model, a pipeline X-ray detection auxiliary device includes a frame 1, on which a travel mechanism 5 can be adjusted, two support tubes 2 are installed in parallel in the middle of the frame 1, and two sleeves 3 are movably mounted on the support tubes 2. A half-frame-shaped support rod 6 is connected to the sleeve 3 located at the same end of the two support tubes 2, and the upper parts of the two support rods 6 are intersected and hinged to form an X-shaped support frame for installing an X-ray machine.

[0027] In the present application, at least four moving mechanisms 5 are provided, and in this embodiment, four are provided, which are respectively located at the four corners of the frame 1, driving the frame 1 to move as a whole. The overall structure of the frame 1 is a rectangular structure, and its width should be smaller than or match the inner diameter of the medium or large diameter pipeline to be inspected, so that it can run inside the pipeline. The two support tubes 2 are respectively located at the two ends of the frame 1 in the length direction.

[0028] The traveling wheel on the traveling mechanism near the end of the safety ring is driven to rotate by power, and a micro motor can be set to drive it; while the traveling wheel on the traveling mechanism away from the other end of the safety ring is driven by power or without power.

[0029] The X-shaped support frame is moved on the support pipe 2 through the sleeve 3, so as to adjust the opening or height of the X-shaped support frame to make it more suitable for the inner diameter of different pipes. The end of the support rod 6 is hinged with the sleeve 3 through the connecting block 33, such as Figure 4 The sleeve 3 is provided with a sleeve connection hole 32, and the support tube 2 is provided with a plurality of support tube connection holes 21. The sleeve 3 slides on the support tube 2 and the sleeve connection hole 32 is fixedly connected with the support tube connection hole 21 by a fixing bolt 31, thereby adjusting the distance between the two support rods 6, that is, adjusting the opening or height of the X-shaped support frame.

[0030] That is, according to the inner diameter of the pipeline to be tested, the distance between the traveling mechanism 5 and the frame 1 is adjusted first, and then the height of the X-shaped support frame is adjusted so that the entire device can run just inside the pipeline. Then the X-ray machine is placed on the upper part of the X-shaped support frame; the traveling mechanism 5 is controlled to move in the pipeline until the radiation source of the X-ray machine is at the center of the weld to be tested in the pipeline for testing.

[0031] like Figure 2 As shown, the frame 1 is a frame structure formed by connecting two connecting pipes 11 and two mounting pipes 12 which are arranged opposite to each other; one end of the traveling mechanism 5 is embedded in the end of the mounting pipe 12 and fixed.

[0032] In this embodiment, the frame 1, the support tube 2, the sleeve 3, the support rod 6 and the like are made of metal materials, which can be welded with low-carbon steel, stainless steel, aluminum alloy and the like.

Thus, the distance between the traveling wheel 51 and the frame 1 can be adjusted, that is, the width of the entire device can be adjusted according to the size of the inner diameter of the pipeline to be measured.

[0034] The driving shaft of the traveling wheel 51 is connected to the output shaft of the motor, and the motor is connected to a motor controller, wherein the motor and the motor controller can be connected by a cable, which is suitable for the case where the pipeline is short; if the pipeline is long, they can be connected by wireless communication. The motor and the motor controller are commonly used products, which can be purchased directly according to the parameters on the market, and the motor controller is used to control the motor to work, thereby driving the traveling wheel 51 to work. In this embodiment, the motor can be a micro, forward and reverse motor, and can be driven by a battery DC or AC motor.

[0035] In a further solution, the rear end of the frame 1 is equipped with a safety ring 9 and a storage plate 10, and the front end is equipped with a laser marker, a lighting lamp 4 and a camera 7. In this embodiment, the lighting lamp is a rechargeable LED lamp, and the camera can be a wired or wireless camera. The laser marker is a known commercial product, which projects a laser onto the pipeline to form a high-brightness laser ring line for locating the pipeline weld. The installation position is to install the laser marker and the X-ray machine on the frame 1 and be located at the same horizontal line, that is, the laser emitted by the laser marker is exactly located at the annular window position where the X-ray machine emits rays, so that the ray source of the X-ray machine is exactly at the pipeline weld to detect the weld.

[0036] In a further solution, a power socket 8 is installed on the frame 1, one end of the power socket 8 is connected to a power source, and the other end of the power socket 8 is connected to an X-ray machine.

[0037] The safety ring 9 is used to fix the cable, power cord and safety rope of the X-ray machine, the storage plate 10 is used to place the power supply and motor used to drive the travel mechanism; the power socket 8 is used to provide a power interface for the X-ray machine, motor, camera, etc.

[0038] In another embodiment, an anti-roll block for limiting the position of the X-ray machine is fixed on the X-shaped support frame.

[0039] In another embodiment, in order to enhance the overall structural stability of the X-shaped support frame, a reinforcing rod is rotatably connected to the intersection of the upper portions of the two support rods 6 .

[0040] In another embodiment, in order to facilitate the judgment of the distance moved by the sleeve 3, scale lines can be engraved on the support tube 2. The main purpose is to facilitate the staff to observe the distance moved by observing the scales on the support tube 2 when changing the relative positions of the sleeve 3 and the connecting holes on the support tube 2.

[0041] In one embodiment, in order to facilitate the judgment of the distance moved by the adjusting tube 52, scale lines can be engraved on the adjusting tube 52. The main purpose is to facilitate the staff to observe the scale on the adjusting tube 52 when changing the relative position of the adjusting tube 52 and the connecting hole on the frame 1 to determine the distance moved.

[0042] The working process of this utility model:

[0043] First, the wheelbase between the traveling wheels 51 on both sides of the frame 1 and the height of the support rod 6 are determined according to the diameter of the pipeline to be detected, so as to ensure that the radiation source of the X-ray machine is exactly at the pipeline weld when in the pipeline.

[0044] That is, the positions of the adjusting tube 52 and the frame 1, the sleeve 3 and the supporting tube 2 are fixed with detachable screws to ensure that the width and height of the device remain unchanged during use.

[0045] Then fix the X-ray machine on the support rod 6 and reinforce it with anti-roll blocks; then tie the cable, power cord and safety rope of the X-ray machine to the safety ring 9, and place the battery, motor and other components driving the traveling wheel 51 on the storage plate 10;

[0046] Turn on the switches of the laser marker, the lighting and the camera, place the device inside one end of the pipeline, control the motor to move the device toward the inside of the pipeline; determine the relative position of the X-ray machine and the weld to be inspected by observing the camera 7; and control the traveling wheel 52 to move forward or backward in the pipeline. When the laser ring line of the laser marker is relative to the weld of the pipeline, positioning is achieved, that is, the X-ray machine is sent to the specified position to detect the weld.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
