[0002] The heat collecting pipe is an important component of the photo-thermal power generation, which is mainly used for collecting solar heat to heat the fluid medium in the pipe. However, the heat collecting pipes produced by the prior art are generally short in size, and a larger length of heat collecting pipe is required in actual application. Therefore, the heat collecting pipe needs to be welded and lengthened during production. The construction scheme for welding and aligning the heat collecting pipe in the prior art mainly includes aligning by using pipe clamps and aligning tool or aligning by using a stop block to fix the slope. The former is inconvenient to operate and lacks precision, and is not suitable for aligning the heat collecting pipe. The latter is easy to damage the base material. Therefore, it is inconvenient and the effect is poor to weld and align the heat collecting pipe by using the prior art.

[0003] A heat collecting pipe welding auxiliary device and a heat collecting pipe welding auxiliary equipment are disclosed in the prior art with the publication number "CN208913480U", which relates to the field of heat collecting pipe welding.

Each set of heat collecting pipe adjusting assembly includes a sliding seat, a first adjusting piece, a second adjusting piece and at least one pair of support arms. The sliding seat is arranged at the upper end of the support frame and can reciprocate along the width direction of the support frame. The at least one pair of support arms are connected to the sliding seat and used for supporting the heat collecting pipe. The first adjusting piece and the second adjusting piece are respectively connected to the two ends of the support frame in the width direction, and are used for adjusting the distance between the two ends of the support frame in the width direction and the two ends of the sliding seat in the width direction of the support frame, so as to change the inclination angle of the sliding seat relative to the support frame.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0022] Please refer to Figures 1-3 The present application provides a technical solution:

[0023] Embodiment one:

[0024] The application discloses a kind of heat collection pipe welding mouth-to-mouth straightness control device, including positioning seat 1 and mouth-to-mouth mobile seat 2, positioning seat 1 is fixedly installed with rotating bearing frame 4 by positioning table 3, mouth-to-mouth mobile seat 2 is rotatably provided with bearing plate 5 around shaft, the rotating axis of bearing plate 5 is close to the side of positioning seat 1 and is located on the extension line of pipe fitting axis of bearing of rotating bearing frame 4, lifting bearing table 6 is slidably arranged on bearing plate 5, and lifting end of lifting bearing table 6 is fixedly connected with lifting bearing frame 7;

[0025] Rotating bearing frame 4 and lifting bearing frame 7 are respectively provided with pipe fitting one 8 and pipe fitting two 9, laser positioning slider 10 is slidably arranged in pipe fitting one 8, and wire bundle emission slider 11 is slidably arranged in pipe fitting two 9 and cooperates with laser positioning slider 10, and the straightness and distance of pipe fitting one 8 and pipe fitting two 9 are calibrated by emitting mouth-to-mouth laser wire bundle 12 to laser positioning slider 10 through wire bundle emission slider 11, and the rotating angle of bearing plate 5 and the lifting height of lifting bearing table 6 are controlled according to the irradiation position of mouth-to-mouth laser wire bundle 12.

[0026] In the embodiment, positioning seat 1 and mouth-to-mouth mobile seat 2 are used as the bearing device of various components, wherein rotating bearing frame 4 and lifting bearing frame 7 support pipe fitting one 8 and pipe fitting two 9 through the support rollers arranged, and realize welding operation after mouth-to-mouth through synchronous rotation, wherein rotating bearing frame 4 is fixedly arranged, and lifting bearing frame 7 is used to adjust lifting, angle and distance, specifically, rotating bearing frame 4 is installed on bearing plate 5, and the angle of lifting bearing frame 7 is adjusted by rotating bearing plate 5 around mouth-to-mouth mobile seat 2, and lifting bearing table 6 drives lifting bearing frame 7 to move up and down through lifting movement, and lifting bearing table 6 in the embodiment is a hydraulic electric lifting cylinder structure, and the lifting movement of lifting bearing table 6 is controlled through built-in PLC control module, in addition, laser positioning slider 10 and wire bundle emission slider 11 are arranged in pipe fitting one 8 and pipe fitting two 9 respectively, wherein wire bundle emission slider 11 is used to emit laser wire bundle, which is used to measure the distance between laser positioning slider 10 and wire bundle emission slider 11, and is used to determine the straightness between pipe fitting one 8 and pipe fitting two 9 by the position of mouth-to-mouth laser wire bundle 12 irradiated on laser positioning slider 10, specifically, refer to the attached drawings of the specification Figure 3It can be seen that when the laser line beam 12 is irradiated on the position above the crosshair of the laser positioning slider 10, the height of the lifting receiving stand 6 is adjusted until the laser line beam 12 can be vertically irradiated to the target position of the crosshair of the laser positioning slider 10, so that the angle of the lifting receiving stand 7 and the angle of the movement of the receiving plate 5 are automatically adjusted by the position of the laser line beam 12 irradiated on the laser positioning slider 10. Compared with the manual adjustment method, the alignment accuracy is higher, and the whole adjustment process is completely automatic, which saves the manual adjustment and calibration steps, greatly improves the alignment efficiency, and at the same time, after the alignment is completed, the laser positioning slider 10 to the line beam emitting slider 11 can also be cleaned inside the pipe by sliding inside the pipe 8 and the pipe 9. In the actual production process, due to the manufacturing process, the pipe may have a certain probability of straightness abnormality and other defects, so after the alignment is completed, the laser positioning slider 10 to the line beam emitting slider 11 slides inside the pipe, and by recording the irradiation position of the alignment laser line beam 12 on the laser positioning slider 10 and the distance where the abnormality occurs, the length position where the straightness defect occurs in the pipe can be accurately determined. Specifically, it is assumed that after the laser positioning slider 10 to the line beam emitting slider 11 is aligned, the laser positioning slider 10 is driven to slide into the pipe body away from the line beam emitting slider 11. Since the alignment operation has been completed before sliding, under normal circumstances, the alignment laser line beam 12 is always vertically irradiated to the target position of the crosshair during the movement of the laser positioning slider 10. At this time, if the laser positioning slider 10 is measured at a distance of 2m from the other end, the alignment laser line beam 12 deviates. Since the line beam emitting slider 11 is in a stationary state, the distance between the two initial states can be used to determine the length position where the straightness defect occurs in the pipe 8 where the laser positioning slider 10 is placed. At the same time, according to the deviation range, it is determined whether to use normally or to be scrapped. Similarly, when the laser positioning slider 10 moves to the far end of the pipe 8 and stops, the line beam emitting slider 11 is driven to slide away from the pipe 8. At this time, according to the position and distance of the irradiation of the alignment laser line beam 12, the position of the straightness defect in the pipe 9 can be determined. After the pipe 8 and the pipe 9 on both sides complete the alignment and the straightness detection, the lifting receiving stand 6 is moved to the side of the positioning seat 1. At this time, when the distance between the pipe 8 and the pipe 9 reaches the welding distance requirement, the welding operation of the heat collecting pipe can be performed. The above operation synchronously completes the alignment, pipe wall cleaning and straightness detection before welding, has multiple functions, higher integration, and is suitable for wide promotion.

The receiving plate 5 is pushed to perform arc rotation around the rotating shaft through the rotation of the mobile wheel 15. The drive motor is arranged on the axle of the mobile wheel 15 and is electrically connected with the system PLC control module, so as to adjust the left and right positions of the laser beam 12 irradiated on the laser positioning sliding block 10.

[0029] In example three, the lifting receiving table 6 is a pair, the bottom of the lifting receiving table 6 is slidingly arranged in the opposite sliding groove 16, the receiving plate 5 is further provided with an opposite screw rod 17, the lifting receiving table 6 is internally provided with a threaded hole matched with the opposite screw rod 17, and the opposite screw rod 17 rotates under the drive of an opposite motor 18 to drive the lifting receiving table 6 to synchronously slide and translate. When the alignment and straightness detection are completed, the welding preparation stage is performed. At this time, the opposite motor 18 is manually controlled to rotate, thereby driving the lifting receiving table 6 to move close to the pipe 8. When the pipe 8 and the pipe 9 reach the welding distance, the rotation of the opposite motor 18 is stopped, and the welding process is entered.

[0031] In this embodiment, the laser positioning sliding block 10 and the beam emitting sliding block 11 are both cylindrical structures and are provided with sealing matching rings 19 on the outside. The laser positioning sliding block 10 and the beam emitting sliding block 11 are sequentially and successively slid from the near end to the far end of the pipe 8 and the pipe 9, and the specific structure is shown in the accompanying drawings. Figure 1, laser positioning slider 10 and wire bundle emission slider 11 are sequentially translated from the near end to the far end, when laser positioning slider 10 and wire bundle emission slider 11 are at the near end of pipe one 8 and pipe two 9, at this time, the pipe one 8 and pipe two 9 are completed, then laser positioning slider 10 moves away from the side of wire bundle emission slider 11, in order to detect the straightness defects in pipe one 8, then wire bundle emission slider 11 slides away from the side of laser positioning slider 10, in order to detect the straightness defects in pipe two 9, wherein the sliding translation device of laser positioning slider 10 and wire bundle emission slider 11 can be realized by mechanical or manual traction, further, the translation sliding of laser positioning slider 10 and wire bundle emission slider 11 is realized by negative pressure, the far end of pipe one 8 and pipe two 9 is provided with negative pressure adsorption seat 20, the negative pressure adsorption seat 20 on both sides is through emptying the gas inside the pipe body to form a negative pressure environment to promote the movement of laser positioning slider 10 or wire bundle emission slider 11, in addition, because laser positioning slider 10 may cause axial rotation during sliding, and it is difficult for manual to keep the crosshair in a horizontal state every time the laser positioning slider 10 is placed inside the pipe, therefore, laser positioning slider 10 includes cylindrical shell 21 and internally rotating wire bundle positioning plate 22, wire bundle positioning plate 22 is internally provided with bottom counterweight, wire bundle positioning plate 22 is in a horizontal crosshair state at all times under the push of bottom counterweight, through the gravity of bottom counterweight itself, makes the wire bundle positioning plate 22 of laser positioning slider 10 can keep the horizontal state of crosshair no matter in what kind of rotating state of cylindrical shell 21, the significance of this kind of setting is to ensure the accuracy of laser positioning, and further provides accurate basis for the lifting of lifting support platform 6 and the rotation of support plate 5, ensures that the automatic alignment program can be successfully completed.
