Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, in particular to a DR equipment shelf convenient for pipeline weld detection. Background Art

[0002] Digital radiography (DR) uses the X-rays or γ-rays emitted by an X-ray machine to penetrate a pipeline to be measured. Due to the attenuation characteristics, the intensity of the rays transmitted through different thickness regions will be weakened to varying degrees relative to the incident intensity. The rays transmitted through the pipeline to be measured are received by a flat panel digital detector and converted into digital signals, and the digital signals are sent to a computer for processing to form digital images.

[0003] In the prior art, DR equipment is often used for pipeline weld quality detection. For example, CN219669087U discloses a special shelf for DR equipment. The X-ray machine is fixedly installed in the arc-shaped frame on the topmost layer, and the part emitting X-rays faces the detector below. The pipeline to be measured is placed in the V-shaped frame on the middle layer. By adjusting the position of the pipeline on the shelf, the pipeline weld is located within the X-ray region to achieve detection of any position of the pipeline. The above scheme has the following problems: When detecting multiple welds on the pipeline in sequence, it is necessary to manually move the position of the pipeline on the shelf multiple times to make the pipeline weld located within the X-ray emission region. Content of the Utility Model

[0022] As Figure 1 shown, this embodiment provides a DR equipment shelf convenient for pipeline weld detection, including a support frame, a linear travel mechanism 2, and a storage rack 3.

[0023] Specifically, the support frame includes a bottom plate 11, a lower support bracket 12, an upper support bracket 13, and a three-dimensional frame 14. Four feet are provided at the bottom of the bottom plate 11. The three-dimensional frame 14 is arranged on one side of the top of the bottom plate 11. The upper support bracket 13 is horizontally slidably arranged on the top of the three-dimensional frame 14. The upper support bracket 13 is used to install the optical machine 4. The bottom of the upper support bracket 13 extends to the storage rack 3 and is fixedly connected to the storage rack 3. The lower support bracket 12 is arranged on the three-dimensional frame 14, and the lower support bracket 12 is located below the upper support bracket 13. The lower support bracket 12 is used to place the pipeline to be tested. The bottom surface of the storage rack 3 is closely attached to the bottom plate 11. The storage rack 3 is used to place the detector 5 and the controller 6.

[0024] The linear travel mechanism 2 is arranged on the bottom plate 11. The linear travel mechanism 2 is connected to the storage rack 3 and is used to horizontally move the storage rack 3 and the upper support bracket 13, so as to move the optical machine 4 to a specific position, ensuring that the X-ray emitting part of the optical machine 4 is aligned with the weld of the pipeline to be tested, thus solving the problem of manually moving the pipeline multiple times.

[0025] More specifically, as Figure 1 、 Figure 2 shown, the storage rack 3 includes two layers of partitions 31 and four vertical rods 32 arranged between the two layers of partitions 31. The detector 5 and the controller 6 are respectively placed on the two layers of partitions 31, and the detector 5 is located above the controller 6 so that the detector 5 can receive the rays emitted by the optical machine 4.

[0026] More specifically, there are many implementation methods for the linear travel mechanism 2, such as Figure 1 、 Figure 4As shown in the figure, in this embodiment, the linear travel mechanism 2 includes a motor 21, a lead screw 22 and an adjustment block 23. There are two substrates provided on the top of the bottom plate 11. The lead screw 22 is rotatably arranged between the two substrates. One end of the output shaft of the motor 21 is connected to the lead screw 22. The adjustment block 23 is fixedly connected to the storage rack 3, and the adjustment block 23 is also threadedly connected to the lead screw 22. When in use, the motor 21 drives the lead screw 22 to horizontally move the storage rack 3 and the upper support 13.

[0027] For the convenience of assembling the three-dimensional rack 14 and also for the convenience of adjusting the height of the optical machine 4, as Figure 1 、 Figure 3 shown, the three-dimensional rack 14 includes two columns 141 and two telescopic rods 142. The two columns 141 are fixedly arranged on the bottom plate 11. The two telescopic rods 142 are respectively slidably fitted up and down with the corresponding columns 141, and the telescopic rods 142 are locked by pins. There are two first cross bars 143 distributed vertically between the two telescopic rods 142.

[0028] More specifically, as Figures 1-3 shown, the upper support 13 includes a vertical plate 131, four first sliders 133 and two arc brackets 132. The four first sliders 133 are arranged in a two-row and two-column array and are respectively slidably fitted with the two first cross bars 143. The top of the arc bracket 132 is connected to the upper first slider 133, and the bottom of the arc bracket 132 is connected to the lower first slider 133 through a reinforcing rod. There is a cross beam between the bottoms of the two arc brackets 132. The optical machine 4 is placed in the two arc brackets 132 and is fixed to the cross beam by two clamps. One side of the first slider 133 away from the arc bracket 132 is connected to the vertical plate 131 through an extension rod 135, and the bottom of the vertical plate 131 is connected to the storage rack 3.

[0029] As mentioned above, the two telescopic rods 142 are respectively slidably fitted up and down with the corresponding columns 141, and the telescopic rods 142 are locked by pins. To achieve this function, two vertical grooves need to be provided on the vertical plate 131. One end of the extension rod 135 facing the vertical plate 131 is provided with a T-shaped block, and the T-shaped block is slidably fitted up and down with the corresponding vertical groove.

[0030] More specifically, as Figures 1-3 、 Figure 5 shown, the lower support 12 includes a plurality of sliding members and a plurality of V-shaped brackets 124. Each sliding member includes an intermediate plate 125 and second sliders 123 provided at both ends thereof. There are two second cross bars 144 distributed vertically between the two columns 141. The second sliders 123 are slidably fitted with the corresponding second cross bars 144. The top of the V-shaped bracket 124 is connected to the upper second cross bar 144, and the bottom of the V-shaped bracket 124 is connected to the lower second cross bar 144 through a reinforcing rod. The V-shaped bracket 124 is used to place the pipeline to be measured, and the V-shaped bracket 124 can adapt to pipelines of various specifications.

[0031] When detecting multiple welds on a pipeline in sequence, there may be a situation where the first weld is located between two adjacent V-shaped brackets 124, but one of the other welds may exactly coincide with the V-shaped bracket 124. That is to say, the V-shaped bracket 124 will affect the detector 5's reception of the rays emitted by the light machine 4, thereby affecting the detection result. To solve this problem, in the above solution, the V-shaped bracket 124 and the sliding member can slide along the second cross bar 144, so as to move the V-shaped bracket 124 that coincides with a certain weld to the left or right by a certain distance, ensuring that the weld is between two adjacent V-shaped brackets 124.

[0032] However, in the above solution, it is necessary to manually move the positions of the V-shaped bracket 124 and the sliding member. To automatically move the positions of the V-shaped bracket 124 and the sliding member, the following measures are taken in this embodiment:

[0033] First, it should be noted that for different pipelines to be measured, the number and positions of their welds may be different. Therefore, each V-shaped bracket 124 may coincide with a certain weld. Then, to automatically move the V-shaped bracket 124, it may be necessary to set up multiple power sources, with each power source connected to a V-shaped bracket 124 to move the position of that V-shaped bracket 124. However, this solution requires multiple power sources and has a high cost. The following measures are taken in this embodiment:

[0034] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 shown, the lower layer bracket 12 further includes a regulation plate 121 and two cylinders 122. The regulation plate 121 is located between the vertical plate 131 and the second cross bar 144. The regulation plate 121 is provided with a plurality of symmetrically distributed sliding grooves 1211. The distance between any two adjacent sliding grooves 1211 is equal, and the distances at both ends of two adjacent sliding grooves 1211 are not equal. A cylinder is provided on the side wall of the middle plate 125. A convex plate is provided at one end of the cylinder away from the middle plate 125. The diameter of the convex plate is larger than the diameter of the cylinder. The cylinder is slidably fitted in the corresponding sliding groove 1211, and the convex plate is in close contact with the regulation plate 121. Sliding sleeves 126 are respectively provided at both ends of the bottom of the regulation plate 121. The sliding sleeves 126 are slidably fitted in the corresponding columns 141. The two cylinders 122 are vertically arranged on the bottom plate 11. The top of the cylinder 122 is connected to the corresponding sliding sleeve 126. The cylinder 122 is used to control the height of the sliding sleeve 126 and the regulation plate 121 to adjust the distance between two adjacent V-shaped brackets 124. The cylinder 122 can also be replaced by an oil cylinder or a hydraulic cylinder.

[0035] The usage method is as follows: The cylinder 122 moves the sliding sleeve 126 and the regulation plate 121 upward. The regulation plate 121 causes the cylinder to move along the chute 1211, and further causes the V-shaped bracket 124 to move along the second cross bar 144, so as to adjust the distance between two adjacent V-shaped brackets 124, ensuring that each weld of the pipeline does not coincide with the V-shaped bracket 124; Place the pipeline to be tested in the V-shaped bracket 124; The motor 21 drives the lead screw 22 to horizontally move the whole of the placement rack 3, the upper support 13 and the optical machine 4, so that the part of the optical machine 4 that emits X-rays is aligned with one of the welds.

[0036] The above embodiments are only used to illustrate the technical idea and characteristics of the present invention, and do not represent the only or limit the present invention. Those skilled in the art should understand that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention all fall within the scope of protection of the present invention.
