Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, and particularly relates to a DR detection system and its tooling fixture. Background Technique

[0002] Regarding industrial DR, in DR technology, X-rays are used to penetrate the pipeline to be inspected. 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 passing through the workpiece 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. DR technology is one of the fast and efficient ray imaging technologies and can obtain digital images within a few seconds. A portable DR detection system generally consists of a ray machine, a digital detector array, a computer, software, cables, power cords, network cables, etc.

[0003] Combined with the attached drawings of the specification Figure 6 As shown, during DR detection work, the detector should be in a relatively perpendicular position to the ray source. Currently, the common equipment maintains this positional relationship by tying a rope between the detector and the ray source. This is not only time-consuming and laborious but also may not ensure that the detector and the ray source are in a relatively perpendicular position to the pipeline during the tying process, resulting in poor imaging effects. At the same time, for a single weld of a pressure pipeline, at least 3 films need to be taken around the weld for a small-diameter pipeline, and about 5 films for a large-diameter pipeline; in the existing method, when using a rope to fix, the operations of disassembling and tying need to be repeated several times, which is time-consuming and laborious. In the prior art, detecting a single joint usually requires manual operation close to the radiation source multiple times, which inevitably exposes the operator to the radiation source irradiation area.

[0004] In view of this, in order to study and improve the problems of inconvenient fixation and time-consuming and laborious of DR detection equipment in the prior art, a tooling fixture for fixing industrial DR equipment and a DR detection system are provided, aiming to solve the problems through this technology and achieve the purpose of improving practical value.

[0047] Embodiment 1

[0048] Please refer to Figures 1-5, this embodiment provides a tooling fixture, including: clamping blocks, guide rails, and a ring 9. The clamping blocks are arc-shaped and arranged in pairs; the paired clamping blocks are used to clamp and fix the pipeline; the guide rails are annular and sleeved outside the paired clamping blocks; the ring 9 is arranged on the first side of the guide rail; paired sliding rods 6 are fixed on the ring 9; the first end of the sliding rod 6 is slidably connected to the guide rail, and the second end of the sliding rod 6 is connected to a mounting seat 7 for fixing the equipment; preferably, the rod body of the sliding rod 6 is connected to the ring 9. Among them, the connection line of the paired sliding rods 6 passes through the center of the cross-section where the connection line on the pipeline is located; the ring 9 is used to drive the sliding rod 6 to rotate around the pipeline along the guide rail.

[0049] It can be seen that the first device fixedly installed on one mounting seat 7 and the second device fixedly installed on the other mounting seat 7 are in a relative state, and the connection line (the connection line is virtual) between the first device and the second device passes through the center of the circular cross-section where the connection line on the pipeline is located. Using this principle, the first device is set as a radiation source / radiographic machine, and the second device is set as a detector / digital detector. The radiation emitted by the first device vertically irradiates the wall of the pipeline and is then received by the second device and converted into a digital signal. The digital signal is sent to a computer for processing, thereby forming a digital image. Further, when the ring 9 rotates, it drives the paired sliding rods 6 to rotate synchronously. At this time, while the first device and the second device on the mounting seat 7 maintain their relative positions unchanged and the connection line between the two always passes through the center of the circle, the first device and the second device rotate to another position to continue detecting the pipeline at that position, which is flexible and convenient for detection, and there is no need to reinstall the tooling fixture, the first device, and the second device.

[0050] In one embodiment, a T-shaped chute 3 is provided on the guide rail, and a slider matching the T-shaped chute 3 is formed at the first end of the sliding rod 6. The sliding rod 6 can be called a T-shaped sliding rod. Preferably, the slider is disk-shaped. When the guide rails are two pieces with the same structure and symmetrically arranged (i.e., the first guide rail 1 and the second guide rail 2), the T-shaped chutes 3 can also be butted against each other to form a complete ring. At this time, the sliding rod 6 rotates 360 degrees around the pipeline inside the T-shaped chute 3.

[0051] In one embodiment, the guide rail includes: a first guide rail 1 and a second guide rail 2. First joints are formed at both ends of the first guide rail 1; second joints are formed at both ends of the second guide rail 2; after the first joint is butted against the corresponding second joint, the first guide rail 1 and the second guide rail 2 form a ring.

[0052] In one embodiment, the clamping block is a telescopic clamping block 5. The pipeline between the two is clamped by driving the two telescopic clamping blocks 5 to move towards each other, and the pipeline clamped between the two is loosened by driving the two telescopic clamping blocks 5 to move away from each other. Specifically, a screw rod is connected to each telescopic clamping block 5 for pushing and pulling the telescopic clamping block 5 to clamp or loosen the pipeline; the first end of the screw rod is movably connected to the center of the convex surface of the telescopic clamping block 5, the second end of the screw rod passes through the guide rail and is connected to the handle 4, and the rod body of the screw rod is threadedly connected to the guide rail. It can be seen that the telescopic clamping block 5 can be driven by the screw rod to clamp and fix pipelines with different diameters within a certain range, further improving its flexibility in use.

[0053] In one embodiment, when the telescopic clamping block 5 clamps the pipeline, the telescopic clamping block 5, the guide rail and the ring 9 are concentric in the same cross-section. This is to ensure that the first device and the second device on the mounting seat 7 maintain a relative position unchanged and the connection line between the two always passes through the center of the circle, and the connection line is perpendicular to the wall of the pipeline at the passing position.

[0054] In one embodiment, the ring 9 can be divided into a first ring and a second ring which are symmetrically arranged and have the same structure. A pair of support seats 8 are fixed on the rod body of each sliding rod 6. The two ends of the first ring and the second ring are inserted and installed between the two support seats 8, and the ring 9 and the support seats 8 are fixed by a pin shaft 10 to connect the first ring and the second ring into a whole ring 9 in a ring shape.

[0055] In one embodiment, the tooling fixture includes a driving mechanism for driving the ring 9 to rotate. For example, forms such as chain drive, belt drive, and synchronous belt drive can be used to drive the ring 9 to rotate. Among them, gear 12 transmission is a common transmission form. Specifically, the ring 9 is a toothed ring; the driving mechanism includes: a driving motor 11 and a gear 12; the driving motor 11 is fixed to the guide rail; the gear 12 is sleeved on the output shaft of the driving motor 11 and meshes with the toothed ring. When the driving motor 11 drives the gear 12 to rotate, the toothed ring can be driven to rotate synchronously.

[0056] In one embodiment, the toothed ring is an external toothed ring, and the gear 12 is correspondingly an external gear 12; the driving motor 11 is fixed to the outside of the guide rail. Of course, the toothed ring can be an internal toothed ring, and the gear 12 is correspondingly an external gear 12; the driving motor 11 is fixed to the inside of the guide rail.

[0057] The tooling fixture of the present utility model enables the T-shaped slide bar to slide along the T-shaped chute 3, so that the tooling fixture can rotate 360° under the control of the ring 9, facilitating radiography of different positions of the pipeline weld at one time without repeatedly disassembling and bundling the detector and the radiation source, further improving the flexibility of use and making it more practical; and the driving motor 11 drives the ring 9 to rotate through the gear 12 fixedly installed on the output shaft, thus realizing automation. The two ends of the ring 9 are inserted and installed on the support seat 8, and the ring 9 and the support seat 8 are fixed by the pin shaft 10, so that the two can be guaranteed to be on the same corresponding horizontal line, thus ensuring that the detector and the radiation source can be in a relatively perpendicular state to the wall of the pipeline to be inspected, improving the detection effect. Through the improvement of the above tooling fixture in terms of structure, a DR device is fixedly installed on the mounting seat 7, making the device have the advantages of simple and convenient detection operation, high degree of automation, good detection effect, more practical performance and practical value, thus effectively solving the problems and deficiencies in the prior art.
