[0041] The support plate 511 is a retractable structure, which is driven to retract by an external driving device 3 (such as an electric telescopic rod, not shown in the figure), so that after the L-shaped pipe 2 moves to just above the horizontal pipe 1, it is driven to descend and align with the upper side wall of the horizontal pipe 1.

[0043] During specific operation, the first screw rod 524 is driven to rotate by the motor, and the first screw rod 524 drives the nut fixing block 525 to reciprocate up and down, thereby driving the track slot plate 521 to reciprocate up and down synchronously. During the up and down reciprocating movement of the track slot plate 521, the sliding cooperation between the guide rod and the track slot drives multiple mounting plates 526 to move left and right, thereby adjusting the distance between the mounting plates 526.

[0044] See also Figure 5 , Figure 6 and Figure 7 The synchronous clamping assembly 53 includes a clamping member, and each mounting plate 526 is slidably mounted with a group of clamping members on the side away from the square frame 512, and a driving member is arranged between the extension plate 522 and the clamping member; the driving member simultaneously drives multiple clamping members to synchronously clamp multiple L-shaped pipes 2.

[0045] Each set of clamping parts includes four clamping strips 531 distributed in a matrix, and the corners of the clamping strips 531 close to each other are arc-shaped surfaces, which cooperate with the side of the horizontal section of the L-shaped pipe 2. The four clamping strips 531 are used to clamp and fix the L-shaped pipe 2; a third slide groove is horizontally opened on the mounting plate 526 corresponding to the position of the clamping strip 531, and a vertical slide plate 532 is slidably installed between the two corresponding third slide grooves, and a fourth slide groove is vertically opened on the side of the vertical slide plate 532 away from the mounting plate 526, and the clamping strip 531 is slidably installed in the fourth slide groove. The distance between the four clamping strips 531 can be adjusted to adapt to the clamping of pipes of different diameters and facilitate the placement of pipes.

[0046] The driving member includes a retractable rod 533 connected between the extension plate 522 and the clamping member, and both ends of the retractable rod 533 are rotatably connected to the extension plate 522, one end of which passes through the extension plate 522 and is connected to an external driving device (not shown in the figure); the retractable rod 533 is composed of a plurality of fixed sections and retractable sections that are alternately connected, and the fixed section is provided with two threaded grooves with opposite rotation directions, and is threadedly connected to the two clamping strips 531 on the same horizontal plane.

[0047] The driving member also includes a plurality of screw rods 534 threadedly connected between two clamping strips 531 in the same vertical plane. The upper and lower ends of the screw rods 534 pass through the clamping strips 531, and a limit block 535 is provided at one end, and a pulley 536 is fixedly installed at the other end. The plurality of pulleys 536 are connected by belts, and one of the screw rods 534 is connected to an external driving device 2 (not shown in the figure). The thread direction of the screw rod 534 at the connection between the two clamping strips 531 in the same vertical plane is opposite to that of the thread.

[0048] During specific operation, the retractable rod 533 is driven to rotate through an external driving device 1, thereby driving the two horizontal clamping bars 531 threadedly connected thereto to move closer to or farther from each other, and due to the existence of the vertical slide plate 532, the other two clamping bars 531 on the same horizontal plane are driven to move synchronously; one of the screw rods 534 is driven to rotate through an external driving device 2, and the other screw rods 534 are driven to rotate synchronously through a belt transmission mechanism, thereby driving the two vertical clamping bars 531 to move closer to or farther from each other; the above-mentioned mechanism is used to realize the synchronous clamping and fixation of multiple horizontal sections of L-shaped pipes 2, and can adapt to L-shaped pipes 2 of different diameters.

[0049] In the same group of clamping parts, arc grooves are provided on the opposite sides of the two clamping strips 531 located below the same horizontal plane, and the arc grooves are in contact with the vertical section of the L-shaped pipe 2; through the arc grooves contacting the vertical section of the L-shaped pipe 2, when the external driving device works, the two horizontal clamping strips 531 in the same group of clamping parts are close to each other to clamp the L-shaped pipe 2, so that the L-shaped pipe 2 is kept in a vertical state synchronously.

[0050] See also Figure 8The clamping assembly 54 includes a U-shaped plate 542, the U-shaped plate 542 is opened to the left, and the ends of the two parallel sections away from the middle section are slidably connected to the vertical plate through an L-shaped rod 543. The bottom of the middle section of the U-shaped plate 542 is fixedly connected to a clamping plate 541 through an elastic telescopic straight rod. The clamping plate 541 is a semi-arc structure with a concave surface facing downward; limiting grooves are provided on the front and rear sides of the vertical plate, and the horizontal section of the L-shaped rod 543 is slidably connected in the limiting groove. A sliding block 544 is slidably connected in the limiting groove, and a spring is provided between the sliding block 544 and the horizontal section of the L-shaped rod 543. Connection; extrusion blocks 545 are arranged on the opposite sides of the two vertical sections of the L-shaped rod 543, and the upper right corner of the extrusion block 545 and the lower left corner of the extension plate 522 are inclined structures with the same inclination angle, and the two cooperate with each other. The upper end face of the extrusion block 545 is consistent in height with the lower end face of the extension plate 522. In the initial state, that is, when the extension plate 522 has not yet contacted the extrusion block 545, the height of the central axis of the clamping plate 541 is lower than the height of the central axis of the horizontal section of the L-shaped pipe 2, and the right side of the clamping plate 541 is a structure that gradually tilts upward from left to right, which is convenient for the L-shaped pipe 2 to enter.

[0051] During specific operation, under the action of the moving assembly 51, the L-shaped pipe 2 approaches the vertical plate, and the horizontal section of the L-shaped pipe 2 first moves to the bottom of the pressing plate 541, and then the vertical section of the L-shaped pipe 2 moves to the top of the horizontal pipe 1. At this time, the extension plate 522 is just located on the upper end surface of the extrusion block 545, and the external driving device 3 (such as an electric telescopic rod, not shown in the figure) is started to shorten the support plate 511. The shortening of the support plate 511 drives the L-shaped pipe 2 to descend and gradually makes its vertical section contact with the side wall of the horizontal pipe 1. At the same time, the extension plate 522 squeezes the extrusion block 545, thereby The L-shaped rod 543 drives the U-shaped plate 542 to descend, and then drives the clamping plate 541 to descend. In the above process, the height of the central axis of the clamping plate 541 is lower than the height of the central axis of the horizontal section of the L-shaped pipe 2. The L-shaped pipe 2 squeezes the clamping plate 541 when it enters under it. Under the action of the elastic telescopic straight rod, the clamping plate 541 generates a force that always pushes the L-shaped pipe 2 downward. When the L-shaped pipe 2 descends to the vertical section and gradually aligns with the side wall of the horizontal pipe 1, the force can squeeze the L-shaped pipe 2 to ensure its close fit with the horizontal pipe 1 at the contact point, thereby improving the quality of the welding process.

[0052] See also Fig. 9 and Fig.10, an adjusting member for adjusting the position of the sliding block 544 is also provided on the vertical plate; the adjusting member includes an adjusting rod 546, an adjusting rod 546 is horizontally rotatably provided on the vertical plate and below the limiting groove, a lifting screw 547 is vertically threadedly connected to the sliding block 544, and the other end of the lifting screw 547 is rotatably provided in the vertical plate, a bevel gear is fixedly installed at the end of the adjusting rod 546 located on the inner side of the vertical plate and the end of the lifting screw 547 located on one side of the vertical plate, and the two bevel gears are meshed with each other, a guide rod 548 is also provided at the bottom of the limiting groove, and the sliding block 544 is slidably connected with the guide rod 548; during specific operation, the adjusting rod 546 is rotated, and the lifting screw 547 is rotated through the bevel gear meshing mechanism, thereby driving the sliding block 544 to move in the limiting groove, and then adjusting the downward movement distance of the L-shaped rod 543, the U-shaped plate 542 and the clamping plate 541; the present invention adjusts the downward movement distance of the L-shaped rod 543, the U-shaped plate 542 and the clamping plate 541 to adapt to the compression degree of L-shaped pipes 2 of different sizes when docking with the horizontal pipe 1, thereby ensuring the smooth progress of subsequent welding.

[0053] In order to improve the docking accuracy between the L-shaped pipe 2 and the horizontal pipe 1, the clamping strip 531 is an elastic and retractable structure; when the vertical section of the L-shaped pipe 2 moves above the horizontal pipe 1, there may be a certain deviation between the contact points of the two. Since the connection between the L-shaped pipe 2 and the horizontal pipe 1 is an arc-shaped structure, the position of the L-shaped pipe 2 can be adaptively changed through the retractable structure after the two are in contact, so that its arc-shaped structure can be accurately docked with the side wall of the horizontal pipe 1.

[0054] Working process: S1: According to the length of the horizontal pipe 1, start the electric telescopic rod, so that it drives the positioning columns 43 to move away from each other through the rectangular strip 42 to adjust the distance between the two positioning columns 43, and then place the horizontal pipe 1 to be welded on the supporting plate 41, restart the electric telescopic rod, so that the two positioning columns 43 move toward the horizontal pipe 1, and the positioning columns 43 are inserted into the pipe to lock it.

[0055] S2: According to the diameter of the L-shaped pipe 2, start the external driving device 1 and the external driving device 2 so that the matrix-distributed clamping strips 531 move away from each other, place each L-shaped pipe 2 on multiple groups of clamping parts, and then restart the external driving device 1 and the external driving device 2 so that each clamping part can synchronously clamp and fix multiple L-shaped pipes 2.

[0056] S3: The distance between the multiple L-shaped tubes 2 is adjusted through the spacing adjustment component 52 according to the spacing between the components of the carbon dioxide recovery system. Specifically, the first screw rod 524 is driven to rotate by the motor, and the first screw rod 524 drives the nut fixing block 525 to reciprocate up and down, thereby driving the track groove plate 521 to move synchronously. During the up and down reciprocating movement of the track groove plate 521, the multiple mounting plates 526 are driven to move left and right through the sliding cooperation between the guide rod and the track groove, thereby adjusting the distance between the mounting plates 526.

[0057] S4: The L-shaped pipe 2 is driven to approach the horizontal pipe 1 through the moving component 51. When the vertical section of the L-shaped pipe 2 is located directly above the horizontal pipe 1, the extension plate 522 is just located on the upper end surface of the extrusion block 545. At this time, when the external driving device three, such as the electric telescopic rod, shortens the support plate 511, the shortened support plate 511 drives the L-shaped pipe 2 to descend and makes its vertical section gradually contact with the side wall of the horizontal pipe 1. At the same time, the extension plate 522 squeezes the extrusion block 545, thereby driving the U-shaped plate 542 to descend through the L-shaped rod 543, and then driving the clamping plate 541 to descend, thereby achieving the extrusion of the L-shaped pipe 2 and ensuring its close fit with the horizontal pipe 1.

[0058] S5: Finally, the L-shaped pipe 2 is welded to the connection point of the horizontal pipe 1 by using existing welding equipment.
