In this patent, the optical instrument detection assembly is installed on the slide trolley so that the optical instrument maintains a certain distance from the weld, especially for use in conjunction with the movement of the robotic arm when using a welding robotic arm to operate the fixed track movement of the welding gun. The slide trolley can move with the camera on a fixed plane, ensuring that the optical focus is within the shooting range and that there is no impact or creep that affects the shooting quality of the high-speed camera. However, the patent requires a slide trolley workbench, which is not easy to move and is not convenient for inspecting the girth weld. Utility Model Content

[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0036] like Figures 1 to 8 As shown, a pipeline weld detection device of this embodiment includes a curved track 1, a rail car 2, an optical scanning mechanism 3 and a magnetic switch 4. The rail car 2 is arranged on the outer surface of the curved track 1 and can move along the curved track 1. The optical scanning mechanism 3 is detachably arranged on the rail car 2. The magnetic switch 4 is arranged on the outer surface of the curved track 1 and presses the curved track 1 onto the pipeline through the adsorption force with the pipeline.

[0037] like Figures 1 to 8 As shown, at least one magnetic switch 4 is provided at each end of the curved track 1 of this embodiment. By providing at least two magnetic switches on the curved track, the curved track can be stably adsorbed on the oil and gas long-distance pipeline.

[0038] like Figures 1 to 4 As shown, in this embodiment, the outer surfaces of both ends of the curved track 1 are provided with adsorption surfaces 5, and the magnetic switch 4 is disposed on these adsorption surfaces 5, specifically in the middle of these surfaces. Providing the adsorption surfaces on the curved track facilitates stable adsorption of the magnetic switch. The ends of the adsorption surfaces 5 extend to both sides of the curved track 1. The width of the adsorption surfaces 5 is no less than that of the magnetic switch 4, ensuring that the magnetic switch 4 does not extend beyond the adsorption surfaces 5.

[0039] An optional solution of this embodiment is that the wheels 21 of the railcar 2 are magnetic. In this case, the outer surface of the curved track can be set as a smooth surface, or a groove with uniform width at the top and bottom can be provided to accommodate the wheels. All wheels can be set as magnetic components, or only one or a few wheels can be set as magnetic components to ensure that the railcar 2 does not fall off the curved track. The wheels are magnetic components, and the wheels can attract the oil and gas pipeline, thereby pressing the curved track between the railcar and the oil and gas pipeline. The magnetic attraction force between the wheels and the oil and gas pipeline does not affect the movement of the railcar along the curved track.

[0040] Another optional solution of this embodiment is that the outer surface of the curved track 1 is provided with a track groove extending along its length, and the wheels of the rail vehicle 2 are adapted to be disposed within the track groove and are capable of moving along the track groove. The track groove is elongated and arranged along the arc-shaped extension direction of the outer surface of the curved track 1. The provision of the track groove facilitates the stable operation of the rail vehicle along the curved track. For example, the track groove can be an inverted T-shaped cross-section, allowing the wheels to engage within the inverted T-shaped groove. The track groove can also be an arc structure with the same curvature as the curved track 1, facilitating the rail vehicle's movement along the arc.

[0041] In a preferred embodiment of the present invention, the optical scanning mechanism 3 is detachably connected to the railcar 2 via bolts. By detachably connecting the optical scanning mechanism to the railcar via bolts, the position of the optical scanning mechanism on the railcar can be changed as needed to scan welds at different locations.

[0042] like Figures 5 to 8 As shown, the optical scanning probe 31 of the optical scanning mechanism 3 of this embodiment is placed on one side of the track vehicle 2, and the radial projection of the optical scanning probe 31 in the curved track 1 is spaced apart on one side of the curved track 1. This facilitates scanning of the welds on one side of the curved track by the optical scanning probe, preventing interference from the curved track and the track vehicle in the scanning area. The optical scanning mechanism 3 and optical scanning probe 31 of this embodiment are both prior art. The connections between the various components and the implementation of their functions are also prior art and will not be described in detail.

[0043] Specifically, the outer surface and the inner surface of the arc track 1 are both arc-shaped structures, that is, the arc track 1 is an arc segment intercepted from a cylindrical structure. Figures 1 to 8 Only part of the structure of the curved track 1 is captured in the figure. This facilitates the adaptation of the curved track to the surface of the oil and gas long-distance pipeline.

[0044] Preferably, the angle of the arc structure in this embodiment is less than 180°, and can be selected from 30° to 60°, such as 35°, 40°, 45°, 50°, 55°, etc. This facilitates installation of the arc track on long-distance oil and gas pipelines. The optical scanning mechanism can scan and image the entire girth weld by performing circular motion within a certain range along with the arc track, resolving the drawback of current weld appearance inspections that can only inspect a few points.

[0045] Preferably, the arc track 1 is a steel track. The arc track of different radius can be replaced according to the diameter of the oil and gas long-distance pipeline below, which is low-cost and can adapt to long-distance pipelines of different sizes by replacing only one component, and has strong versatility.

[0046] Specifically, the two side edges of the arc track 1 are arranged in parallel, and the end surfaces of both ends of the arc track 1 are also arranged in parallel with each other.

[0047] The rail vehicle 2 of this embodiment can be a remote-controlled vehicle. The rail vehicle 2 can have four wheels 21 , and the front and rear wheels do not extend beyond the two side edges of the arc-shaped track 1 .

[0048] The arc track of this embodiment is adsorbed on the long-distance oil and gas pipeline below through two magnetic switches, and has strong stability. It solves the problem of inaccurate detection caused by manual fixation in the previous weld inspection process, and largely ensures the accuracy of the appearance inspection of the girth weld. At the same time, the main structure of the optical scanning mechanism has digital functions such as collection and storage, and can directly process the collected data. After subsequent connection with electronic equipment, a large number of functional expansions can be achieved. The main structure of the optical scanning mechanism and the optical scanning probe are fixed to the rail car with bolts, and the measurement of groove angle, blunt edge and other data can be achieved by changing the fixed position.

[0049] The curved track 1 of this embodiment is fixed to the oil and gas pipeline via a magnetic switch 4. The magnetic switch is placed directly on the adsorption surface 5 on the outer surface of the curved track 1. Through the adsorption force of the oil and gas pipeline, the two ends of the curved track 1 are pressed against the pipeline. By installing and removing the magnetic switch 4, it is possible to detect any position on the girth weld of the oil and gas pipeline. The optical scanning mechanism transmits the girth weld appearance data obtained by the optical scanning probe to the optical scanning device body, which can store the data and upload the data in real time by connecting to an external electronic device.

[0050] The working principle of a pipeline weld inspection device of this embodiment is as follows: when in use, the curved track is first fixed to the weld of the long-distance oil and gas pipeline below through a magnetic switch, and then the rail car is moved to make it perform circular motion within a certain range on the curved track. After the optical scanning mechanism completes the scanning, the magnetic switch is turned off, and the entire device is disassembled to complete the appearance inspection of the girth weld.

[0051] The pipeline weld detection device of this embodiment is provided with an arc track, a rail car, an optical scanning mechanism and a magnetic switch. The components cooperate with each other. When in use, the rail car can make circular motion within a certain range along the arc track, and the rail car drives the optical scanning mechanism to scan. The optical scanning mechanism can output the appearance data of the girth weld, thereby realizing the simplification, precision and intelligence of the weld detection work of long-distance oil and gas pipelines. The pipeline weld detection device has a simple structure and a reasonable design. The optical scanning device can scan and output images at any position of the girth weld according to the different positions of the arc track. It is essentially different from the mechanical measurement of the weld detection ruler used in current engineering construction, and the accuracy is greatly improved. At the same time, the collection, transmission and identification of the girth weld appearance data can be realized by different functions of external electronic devices, thereby realizing the digitalization of the appearance detection of girth welds in long-distance oil and gas pipelines.

[0052] This embodiment can improve the level of on-site management, ensure that the project quality is under control, realize the intelligence of construction site measurement tools, and the informatization of measurement data, thereby improving the accuracy of detection data during the construction process and improving work efficiency and quality.
