Description

Technical Field

[0001] This utility model relates to the field of pipeline inspection technology, specifically to a support for the pit inspection environment of a digital X-ray inspection device. Background Technology

[0002] When performing radiographic testing on welded joints of underground PE pipes, workers need to dig a pit in advance and then notify the testing personnel to conduct the on-site inspection. The testing equipment used by the testing personnel consists of two parts: an imaging device and a radiographic device. The imaging device includes an imaging plate, and the radiographic device includes a radiation source. The imaging plate is placed at the bottom of the pipe, and then the radiation source is placed above the imaging plate and the pipe. Ideally, the radiation source should be aligned with the pipe; it should not be placed too high, too low, or at too large an angle to the pipe, otherwise the test results will be affected.

[0003] Normally, a ladder is placed on the ground at the top of the pit, and the X-ray source is positioned on the ladder. The angle of the X-ray source is then continuously adjusted until it is suitable before testing. The problem is that the burial depth of the pipes varies; some are deep, some shallow, some wide, and some narrow. Some pits are as deep as 4-5 meters, while others are only 20-30 centimeters. Therefore, when the pit is too deep or too shallow, the ladder cannot meet the height requirements specified in the X-ray inspection operation manual, affecting the test results. When the pit is wide and the pipe is in the middle, it is difficult to adjust the angle of the X-ray source to align it with the pipe even after climbing the ladder. Similarly, when the pit is deep, it is difficult to align the X-ray source with the pipe. To address this problem, a support structure was developed. Summary of the Invention

[0004] In view of the shortcomings of the prior art mentioned in the background, the present invention provides a bracket that meets the detection environment requirements of digital X-ray inspection equipment for pits of different depths.

[0005] This utility model overcomes the above technical problems by adopting the following technical solution:

[0006] A support frame for a digital X-ray inspection device's pit inspection environment includes a telescopic rod and a bracket at the top of the telescopic rod for placing an X-ray source. The telescopic rod includes four support rods fixedly connected to the bottom of the bracket, an adjusting sleeve sleeved on the outer circumference of the support rod, an adjusting column fixed on the circumference of the support rod and near the bottom of the support rod, and an adjusting ring threadedly connected to the outer circumference of the adjusting sleeve. The outer circumference of the adjusting sleeve is threaded and has a notch along its length. The adjusting ring is threaded. The adjusting column extends from the notch and its bottom is engaged with the adjusting ring. By turning the adjusting ring, the adjusting ring causes the adjusting column to move upward or downward, thus lengthening or shortening the overall length of the telescopic rod.

[0007] The bracket includes a U-shaped base and two support plates mounted on the U-shaped base;

[0008] The two support plates are formed by cutting a circular steel pipe in half. The bottom of the support plate is welded to the base. The specific structure of the support plate is as follows:

[0009] Both of the support plates have a recessed notch on the top surface of the support plate, the notch is semi-circular, and thus the support plate is U-shaped; the width of the support plate, that is, the width of the part in contact with the radiation source, is ≤6cm.

[0010] The radiation source is placed in the notch, and the bottom of the support plate is welded to the support rod.

[0011] The outer circumferential surface of the adjusting ring is provided with at least one handle;

[0012] The length of the support rod is between 0.5m and 2m, and the length of the adjusting sleeve is between 0.5m and 1.5m.

[0013] The telescopic rod and bracket are both made of metal and are coated with an anti-corrosion coating, which is paint.

[0014] Compared with the prior art, this utility model has the following advantages:

[0015] When the pit is shallow, the top of this support protrudes a certain distance above the ground. In other words, the height of the telescopic frame can be adjusted to be higher than the ground to meet the requirements of the detection height.

[0016] When the pit is deep, place this bracket on both sides of the pipe and put it inside the pit, recessed into the ground so that the detection height meets the detection requirements.

[0017] When the pit depth is appropriate, workers can lower the support frame directly into the pit without climbing a ladder to the bottom, and adjusting the direction of the support frame is also relatively convenient.

[0018] When the ground is uneven, turning one of the adjustment rings causes the adjustment column and support rod to rise or fall, thereby lengthening or shortening the telescopic rod and achieving overall balance, thus meeting the environmental testing requirements for uneven ground.

[0019] By adjusting the distance between the two pairs of four adjusting sleeves and the pipe to be inspected, the radiation source and the pipe can be aligned in a straight line. After the telescopic rod is placed stably, the radiation source is placed on the bracket. Generally, the height of the bracket should be set to be convenient for adults to operate and meet the operating procedures. Since there is a groove on the top of the bracket, the radiation source is properly secured in the groove and will not easily roll off. When the pit is wide, this bracket can ensure that the angle of the radiation source and the pipe are aligned in a straight line by following the above operation, thus ensuring the accuracy of subsequent inspections.

[0020] After the test is completed, turn the adjusting ring to the bottom of the adjusting sleeve to complete the storage of the bracket, making it easy to carry and store.

[0021] This device is simple, easy to manufacture, has a robust structure, long service life, and low cost. Attached Figure Description

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] During fabrication, prepare one square steel pipe, two round steel pipes, four threaded rods, two stainless steel plates, and several accessories. First, cut the round steel pipe into four sections to form support rod 1. Cut a steel pipe with a larger diameter from the middle to form two support plates 6. To avoid affecting the detection effect of the radiation source, the width of the cut steel pipe is less than 3cm, and the cut steel pipe serves as the support plate 6. Cut the square steel pipe into four sections and weld them into a U-shaped base 7. Weld the support plates 6 onto the base 7, and weld the support rod 1 under the base 7. Drill holes in the circumference of four adjusting sleeves 2 and fit them onto the support rod 1; these holes are the notches 5. Weld the adjusting column 3 onto the support rod 1, and screw the adjusting ring 4 onto the adjusting sleeve 2. The telescopic rod and bracket are all made of metal and have a painted surface. This device is simple, easy to manufacture, structurally stable, has a long service life, and is low in cost.

[0027] This utility model discloses a support for a digital X-ray inspection equipment pit inspection environment, including a telescopic rod and a bracket at the top of the telescopic rod for placing a X-ray source. The telescopic rod includes four support rods 1 fixedly connected to the bottom of the bracket, an adjusting sleeve 2 sleeved on the outer circumference of the support rod 1, an adjusting column 3 fixed on the circumference of the support rod 1 and near the bottom of the support rod 1, and an adjusting ring 4 threadedly connected to the outer circumference of the adjusting sleeve 2. The outer circumference of the adjusting sleeve 2 is threaded and has a notch 5 along its length. The adjusting ring 4 is threaded. The adjusting column 3 extends from the notch 5 and its bottom is engaged with the adjusting ring 4. By turning the adjusting ring 4, the adjusting ring 4 drives the adjusting column 3 to move up or down, thus lengthening or shortening the overall length of the telescopic rod. After adjusting the angle and achieving balance, the X-ray source is placed in the notch 8. The X-ray source will generate radiation during the inspection process, so it should not be placed too close during the inspection. After placement, the inspection personnel leave and begin remote control and X-ray inspection.

[0028] Example 1:

[0029] When the pit is shallow, only 30cm, the imaging plate is placed at the bottom of the PE pipe, and then the radiation source is placed above the imaging plate and the pipe. The top of the support of the pit detection environment of this digital X-ray inspection equipment protrudes from the ground by a certain distance, and the radiation source is placed on the recess 8. The radiation source, imaging plate and other inspection accessories and control devices in the X-ray inspection device are all purchased from the market and will not be described in detail here. Therefore, the height of the support of the pit detection environment of this digital X-ray inspection equipment is higher than the ground, which meets the inspection height requirements. Therefore, this application can meet the inspection requirements when the pit is shallow.

[0030] Example 2:

[0031] When the pit is 4m deep, a ladder needs to be climbed to the bottom of the pit. The support frame of this digital X-ray inspection equipment for pit inspection is placed on both sides of the pipe and inside the pit, recessed into the ground so that the inspection height meets the inspection requirements. Then the inspection can be carried out. Therefore, this application can meet the inspection requirements when the pit is deep.

[0032] Example 3:

[0033] When the pit depth is appropriate, staff can directly lower the support frame of this digital X-ray inspection equipment into the pit without climbing a ladder to the bottom. Adjusting the direction of the support frame is also relatively convenient.

[0034] Example 4:

[0035] Because the workers who dig the pits are different, the construction quality varies. When the ground is uneven, the inspection personnel can adjust the uneven telescopic rods by turning a certain adjusting ring 4. The adjusting ring 4 drives the adjusting column 3 and the support rod 1 to rise or fall, thereby balancing the support of the digital X-ray inspection equipment for pit inspection and thus meeting the inspection needs of uneven ground.

[0036] In the above four working environments, by adjusting the distance between the two pairs (a total of four) of adjusting sleeves 2 and the pipeline to be tested in the middle, that is, the pipeline is in the middle of the two pairs (a total of four) of adjusting sleeves, the radiation source and the pipeline can be aligned in a straight line, thus ensuring the accuracy of the test results. Since the top of the bracket has a groove, the radiation source is just stuck in the groove and is not easy to roll off.

[0037] In the above four working environments, after the test is completed, the adjusting ring 4 is turned to the bottom of the adjusting sleeve 2 to complete the storage of the bracket, making it easy to carry and store. Since the outer circumference of the adjusting ring 4 is provided with at least one handle 9, it is easy to turn and adjust.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
