[0002] The vertical shaft plays a key role in the field of construction and engineering, which can act as a ventilation pipe or a vertical transportation channel for personnel and equipment, and also facilitates the arrangement and operation of various systems. In order to facilitate the transportation of fluids such as water, gas, heating and gas, different types of pipelines are usually installed inside the vertical shaft according to the needs.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Reference Figures 1-22 A positioning device for welding and butt-joining pipes in a vertical shaft includes a positioning sleeve 1 and a positioning sleeve 4. Two guide cylinders 2 are rotatably mounted through and on the positioning sleeve 1. Two threaded cylinders 3 are fixedly mounted through and on the lower end of the positioning sleeve 4, and both threaded cylinders 3 are threadedly installed inside the corresponding guide cylinders 2 (from...). Figure 11 As can be seen, both guide cylinders 2 have threaded grooves that cooperate with the corresponding threaded cylinders 3. A clamping component 6 is provided between positioning sleeve 1 and positioning sleeve 2. A pressing component 8 is provided between positioning sleeve 1 and positioning sleeve 2. An adjusting component 9 is provided between positioning sleeve 1 and positioning sleeve 2. An air supply component 7 is provided on positioning sleeve 1.

[0042] Combination Figures 1-3It can be seen that both positioning sleeve 1 and positioning sleeve 2 are composed of two semi-annular plates, and adjacent semi-annular plates are connected by corresponding rotating shafts 5. The semi-annular plates are rotatably connected to their respective rotating shafts 5. When construction personnel need to use this equipment to position and connect the pipes to be welded, they can do so manually or mechanically by connecting the two pipes to be welded (e.g., ...) Figure 1 (As shown in the diagram, with the two pipes to be welded set vertically) After adjusting to a suitable distance, the positioning sleeves 1 and 4 are unfolded sequentially by rotating the screws on them. This allows the construction personnel to easily install the positioning sleeves 1 and 4 onto the corresponding pipes to be welded. After the positioning sleeves 1 and 4 are installed on the corresponding pipes, the two semi-annular plates are rotated sequentially to reclose the positioning sleeves 1 and 4. Then, the two screws are reversed sequentially to fix the positioning sleeves 1 and 4 as a whole. This facilitates the clamping and positioning of the two pipes to be welded and the connection between them.

[0043] Reference Figures 1-9 The clamping assembly 6 includes multiple limiting grooves 63 respectively opened on the positioning sleeve 1 and the positioning sleeve 2. Two moving blocks 69 are slidably installed on each limiting groove 63. A spring telescopic tube 610 is fixedly installed between the two moving blocks 69. An arc-shaped pressing plate 611 is fixedly connected to one end of each spring telescopic tube 610. A drive mechanism is installed between the spring telescopic tube 610, the positioning sleeve 1, and the positioning sleeve 2.

[0044] The driving mechanism includes a first groove 61 respectively opened on the first positioning sleeve 1 and the second positioning sleeve 4. The first positioning sleeve 1 and the second positioning sleeve 4 are each provided with a second groove 62, and the two first grooves 61 and the two second grooves 62 are connected to the corresponding limiting grooves 63. The first positioning sleeve 1 and the second positioning sleeve 4 are each connected through and rotatably mounted with a rotating shaft 5. The two rotating shafts 5 are each fixedly mounted with two rotating gears 64. The two first grooves 61 and the two second grooves 62 are each slidably mounted with sliders 65. The two first grooves 61 and the two second grooves 62 are each fixedly mounted with a return spring 66, and the return spring 66 is fixedly connected to the corresponding slider 65. The slider 65 is each fixedly mounted with an arc-shaped rack 67. The end of the arc-shaped rack 67 is fixedly mounted with a rack plate 68 that meshes with the corresponding rotating gear 64. The first positioning sleeve 1 and the second positioning sleeve 4 are jointly installed with a pushing component.

[0045] The pushing component includes threaded rods 612 that are uniformly rotatably mounted on two slide grooves 61 and two slide grooves 62 in an arc shape. Each threaded rod 612 is fixedly mounted with a spur gear 613 that meshes with a corresponding arc-shaped rack 67. Each threaded rod 612 is threadedly mounted with a sliding member 614, and each sliding member 614 is fixedly connected to a corresponding spring telescopic tube 610.

[0046] Combination Figure 4 and Figure 7 It can be seen that the corresponding arc-shaped rack 67 and rack plate 68 are both located inside the corresponding semi-annular plate in the initial position. This helps to avoid the arc-shaped rack 67 and rack plate 68 hindering the rotational displacement of the corresponding two semi-annular plates during the process of unfolding positioning sleeve 1 and positioning sleeve 2 4, that is, during the relative rotation of the corresponding two semi-annular plates.

[0047] When this equipment is needed to position two pipes to be welded, and based on the above operating principle, positioning sleeve 1 and positioning sleeve 4 are respectively placed on top of the corresponding pipes to be welded, and after they are moved to the appropriate position, the lower rotating shaft 5 is first manually rotated (e.g., Figure 1 (as shown in the direction), at this time, during the process of manually driving the rotating shaft 5 to rotate counterclockwise (such as... Figure 6 (In the direction shown), through the cooperation of the two corresponding rotating gears 64 and the two rack plates 68, the two corresponding arc-shaped racks 67 can be driven to rotate and move closer to each other. During the rotation and displacement of the two corresponding arc-shaped racks 67 under force, through the cooperation of the spur gear 613, the threaded rod 612 and the sliding member 614, the multiple corresponding spring telescopic tubes 610 and the multiple arc-shaped pressing plates 611 can be driven to move closer to each other.

[0048] Meanwhile, most of the pipes currently used in vertical shafts are cylindrical. After the construction workers place the positioning sleeve 1 and positioning sleeve 2 4 on the corresponding pipe to be welded, it is difficult for them to accurately determine whether the pipe to be welded is centered on the positioning sleeve 1 and positioning sleeve 2 4. Therefore, if the pipe is not centered on the positioning sleeve 1 or positioning sleeve 2 4, during the process of the corresponding multiple spring telescopic tubes 610 driving the corresponding arc-shaped pressing plates 611 to approach each other, one side of the arc-shaped pressing plate 611 will first contact the side wall of the pipe. At this time, by continuously rotating the corresponding rotating shaft 5, that is, by continuously driving the multiple spring telescopic tubes 610 and the multiple arc-shaped pressing plates 611 to approach each other, the pipe will exert resistance on the arc-shaped pressing plates 611 that are in contact with it, causing the arc-shaped pressing plates 611 to squeeze the corresponding spring telescopic tubes 610 until all the corresponding arc-shaped pressing plates 611 are in contact with the side wall of the corresponding pipe, and cooperate to achieve clamping and positioning.

[0049] By cooperating with the corresponding multiple spring telescopic tubes 610 and the arc-shaped pressing plate 611, the equipment can not only clamp and position different pipes to be welded, but also, through the elasticity of the corresponding multiple spring telescopic tubes 610, can adaptively clamp and position the pipe according to the position of the pipe inside the positioning sleeve 1 (or positioning sleeve 2 4). This can help improve the convenience of the equipment for clamping and positioning pipes and its adaptability to different pipe positioning.

[0050] After the multiple arc-shaped pressing plates 611 on the positioning sleeve 1 cooperate to clamp and position the corresponding pipe to be welded, the upper rotating shaft 5 is rotated according to the above operating principle (e.g., Figure 1 (As shown in the direction), the multiple spring telescopic tubes 610 on the positioning sleeve 2 4 can cooperate with the multiple arc-shaped pressing plates 611 to clamp and position the corresponding pipes to be welded. At this time, the positioning sleeve 1 and the positioning sleeve 2 4 cooperate to position the two pipes to be welded, which can facilitate the subsequent docking of the two pipes and also help improve the stability of the relative position of the two pipes during the subsequent welding process, that is, help improve the subsequent welding effect of the two pipes.

[0051] Reference Figure 1 , Figure 4 , Figure 6 , Figures 9-13 , Figure 22 The gas delivery assembly 7 includes a bracket fixedly mounted on the positioning sleeve 1, an air pump 71 fixedly mounted on the bracket, and an air delivery pipe 72 fixedly connected to the air pump 71. Multiple blocks (shown in the figure but not labeled) are fixedly mounted on the side wall of the positioning sleeve 1. Figure 4 As can be seen from the image, the air duct 72 is installed and fixedly installed between the blocks;

[0052] Two conduits 73 are fixedly connected to the air supply pipe 72, and both conduits 73 are sealed through and fixedly installed on the positioning sleeve 1, and extend to the lower end of the corresponding guide cylinder 2. An air guiding component is installed between the two guide cylinders 2.

[0053] The air guiding components include air inlets (shown in the figure but not labeled) respectively opened on two guide cylinders 2. Figure 13 As can be seen from the image, annular cylinders 74 are rotatably mounted on both guide cylinders 2, and arc-shaped pipes 75 are fixedly connected to both annular cylinders 74. A connecting pipe 76 is fixedly connected between the spring telescopic pipe 610 below the displacement and the corresponding arc-shaped pipe 75. An air supply pipe 10 is fixedly connected to the upper end of both threaded cylinders 3, and an air guide pipe 11 is fixedly connected between the spring telescopic pipe 610 above the displacement and the corresponding air supply pipe 10.

[0054] During the process of driving the multiple spring telescopic tubes 610 and the multiple arc-shaped pressing plates 611 closer together through the above operations (such as...) Figure 1(As shown in the direction), start the air pump 71. At this time, the operation of the air pump 71 can continuously input gas into the two guide cylinders 2 through the cooperation of the air supply pipe 72 and the two conduits 73. Some of the gas entering the two guide cylinders 2 will enter the two arc-shaped pipes 75 along the corresponding air inlet 82, air guide, and annular cylinder 74, and then enter the corresponding multiple spring telescopic pipes 610 along the two arc-shaped pipes 75 and multiple connecting pipes 76, and be blown out through the multiple holes opened on the corresponding multiple arc-shaped pressing plates 611 (from... Figure 9 As can be seen, multiple holes are provided on the side of the arc-shaped pressing plates 611 that are close to each other. When the corresponding multiple arc-shaped pressing plates 611 are subjected to force and gradually approach the side wall of the corresponding pipe to be welded, the gas blown out by the corresponding multiple arc-shaped pressing plates 611 can achieve the effect of automatically cleaning the side wall of the pipe to be welded. This can help improve the fit between the arc-shaped pressing plates 611 and the side wall of the pipe when the corresponding multiple arc-shaped pressing plates 611 cooperate to clamp and position the pipe. In other words, it helps to improve the effect and stability of the subsequent clamping of the pipe by the corresponding multiple arc-shaped pressing plates 611.

[0055] Meanwhile, the air supply pipe 72 is located in the middle of the positioning sleeve 1, that is, the connecting part of the two semi-annular plates below. It is made of elastic material. Through the elasticity of the air supply pipe 72 itself, it can easily adapt to the opening and closing of the positioning sleeve 1.

[0056] Simultaneously, when the air pump 71 operates and gas is input into the two guide cylinders 2, some of the gas entering the two guide cylinders 2 will flow along the two guide cylinders 2 into the two threaded cylinders 3, and then along the two threaded cylinders 3, the two air supply pipes 10, and the multiple air guide pipes 11 into the multiple upper spring telescopic tubes 610, and finally be blown out through the holes opened on the multiple upper arc-shaped pressing plates 611. This achieves a cleaning effect on the surface of the corresponding pipe to be welded when the multiple upper arc-shaped pressing plates 611 are brought closer together under force, which helps to improve the clamping and positioning effect of the multiple upper arc-shaped pressing plates 611 on the corresponding pipe to be welded (e.g., Figure 1 direction shown).

[0057] Once the upper and lower multiple arc-shaped pressing plates 611 are in coordination to blow air and clean the corresponding pipe to be welded, and to complete the clamping and positioning, the operation of the air pump 71 can continuously extract the gas inside the multiple arc-shaped pressing plates 611 through the cooperation of the air supply pipe 72, two conduits 73, two guide cylinders 2 and two threaded cylinders 3. In this way, the clamping and positioning stability of the corresponding pipe to be welded by the multiple arc-shaped pressing plates 611 is further increased by the adsorption of the multiple arc-shaped pressing plates 611, that is, the firmness of the connection between the positioning sleeve 1 and the positioning sleeve 2 and the corresponding pipe to be welded.

[0058] During storage, handling, or processing, pipes used in vertical shafts are prone to dust accumulation due to factors such as static electricity. When this dust accumulates to a certain extent, it reduces the stability of the connection between the docking positioning equipment and the pipe to be welded. In severe cases, the docking positioning equipment may separate from the pipe due to vibration or other factors during the subsequent welding of the two pipes, reducing the positioning effect of the equipment on the two pipes to be welded. Therefore, by using multiple arc-shaped pressing plates 611 in conjunction with air blowing cleaning and adsorption fixation of the pipes to be welded, the stability of the connection between the positioning sleeve 1 and the positioning sleeve 2 and the corresponding pipes to be welded can be improved.

[0059] Meanwhile, multiple connecting pipes 76 and multiple air guide pipes 11 are all made of elastic material. When the spring telescopic pipe 610 is subjected to force and moves horizontally, the elasticity of the connecting pipes 76 and air guide pipes 11 can easily adapt to the stretching or compression of the corresponding spring telescopic pipe 610 during the movement.

[0060] Reference Figures 13-19 The adjusting component 9 includes threaded sleeves 91 respectively installed on two guide cylinders 2. Torsion springs 92 are fixedly installed between the two threaded sleeves 91 and the positioning sleeve 1. An adjusting mechanism is installed between the two threaded sleeves 91 for automatic docking of pipelines.

[0061] The pressing assembly 8 includes multiple slots 87 respectively opened on the positioning sleeve 1 and the positioning sleeve 4. An arc-shaped support plate 85 is slidably installed between each two slots 87. A disc 81 is installed in each of the two guide cylinders 2. An air inlet 82 that cooperates with the corresponding duct 73 is opened on each of the two discs 81. A reciprocating screw 83 is installed through and fixedly installed on each of the two discs 81. A connector 84 is installed on each of the two reciprocating screws 83 through a ball nut. The two connectors 84 are fixedly connected to the corresponding arc-shaped support plate 85. A positioning component is installed between the spring telescopic tube 610 and the arc-shaped support plate 85.

[0062] The positioning components include extrusion plates 88 that are respectively sealed and slidably installed at the lower end of the spring telescopic tube 610. Each extrusion plate 88 is provided with a moving groove 89. Each arc-shaped support plate 85 is fixedly installed with rods 86 that are evenly distributed in an arc shape, and each rod 86 is slidably installed on the corresponding moving groove 89.

[0063] After both positioning sleeve 1 and positioning sleeve 2 4 are securely installed on the corresponding pipes to be welded, stop the operation of air pump 71, and then drive the pipes to be welded on positioning sleeve 2 4 to gradually move down (e.g., ...) by manual or mechanical means. Figure 1(As shown in the direction), so that the upper pipe to be welded gradually approaches the lower pipe to be welded. During this process, since the positioning sleeve 2 4 is installed on the upper pipe to be welded, the positioning sleeve 2 4 will move down along with it. And during the process of the positioning sleeve 2 4 driving the two threaded cylinders 3 to move down together (as shown in the direction), the positioning sleeve 2 4 will move down along with it. Figure 18 (As shown in the direction), the two threaded cylinders 3, through their engagement with the threaded grooves inside the corresponding guide cylinders 2, apply a rotational driving force to the corresponding guide cylinders 2, which can drive the two guide cylinders 2 to rotate.

[0064] When the two guide cylinders 2 rotate under force, the friction between the inner walls of the two guide cylinders 2 and the corresponding discs 81 drives the two discs 81 to rotate together. At this time, as the two discs 81 drive the corresponding reciprocating screws 83 to rotate, the corresponding ball nuts and connecting parts 84 cooperate to drive the two arc-shaped support plates 85 and multiple rods 86 to move upward (e.g., Figure 16 As shown in the direction, that is, the two arc-shaped support plates 85 connected to the positioning sleeve 1), and during the upward movement of the multiple rods 86, the upward thrust applied to the corresponding pressing plate 88 can push the corresponding pressing plate 88 upward and into the interior of the corresponding spring telescopic tube 610 (e.g. Figure 15 (as shown in the direction) to limit the position of the corresponding spring telescopic tube 610. For example, when the extended end of the spring telescopic tube 610 is displaced inside its contracted end, the corresponding pressing plate 88 is forced upward to press the extended end, thus limiting its position. If the extended end of the spring telescopic tube 610 is not inside the corresponding contracted end, the corresponding pressing plate 88 is forced upward to enter the contracted end of the corresponding spring telescopic tube 610, thus limiting the force on the subsequent spring telescopic tube 610, and its extended end enters the contracted end.

[0065] When the multiple curved support plates below move upward under force (such as...) Figure 1 (as shown in the direction), to complete the position limitation of the corresponding spring telescopic tube 610, when the corresponding two connecting pieces 84 contact the lower end of the positioning sleeve 1 (from the direction shown in the direction), Figure 20 As can be seen, when the two connecting parts 84 are initially located at the lower end of the positioning sleeve 1, the resistance exerted by the positioning sleeve 1 on the upward movement of the two connecting parts 84 is greater than the frictional resistance between the two guide cylinders 2 and the corresponding discs 81. Therefore, the two guide cylinders 2 cannot drive the two discs 81 and the reciprocating screw 83 to rotate continuously.

[0066] Reference Figure 1 , Figures 11-22The adjustment mechanism includes a pushing component 98 rotatably mounted on two guide cylinders 2, and both pushing components 98 are engaged with corresponding arc-shaped support plates 85. Each of the two threaded sleeves 91 is threaded with a sliding block 93, and each of the two sliding blocks 93 is fixedly mounted with a support frame 94. Each of the two support frames 94 is fixedly mounted with two telescopic rods 95. Each of the telescopic rods 95 has a support rod 96 that passes through and is fixedly mounted on one end, and the lower end of each support rod 96 is fixedly connected to a corresponding spring telescopic tube 610.

[0067] Each support rod 96 has an adjusting rod 97 fixedly installed at its upper end, and each upper part of the spring telescopic tube 610 has an adjusting plate 99 fixedly installed at its lower end. The adjusting plate 99 is matched with the corresponding adjusting rod 97, and each adjusting plate 99 has an adjusting groove.

[0068] When the rotating shaft 5 cooperates with the clamping assembly 6, driving the multiple spring telescopic tubes 610 on the positioning sleeve 1 to approach each other with the multiple arc-shaped pressing plates 611, the multiple support rods 96 will move together. Therefore, when the multiple arc-shaped pressing plates 611 below cooperate to clamp and position the corresponding pipe to be welded, the pipe is located at the center position of the multiple adjusting rods 97. When the two threaded cylinders 3 are forced to move downward, driving the two guide cylinders 2 to rotate, the position of the multiple spring telescopic tubes 610 below is limited, that is, the position of the lower pipe relative to the positioning sleeve 1 is limited (e.g. Figure 1 (As shown in the direction), it is also possible to limit the position of multiple adjustment levers 97.

[0069] Simultaneously, as the guide cylinder 2 rotates under force, it will cause the two corresponding threaded sleeves 91 to rotate together. During this rotation, the corresponding sliding block 93, support frame 94, and two telescopic rods 95 can be driven to move upward together (e.g., Figure 20 (as shown in the direction), and during the upward movement of the telescopic rod 95, by stretching the upper end of the corresponding support rod 96 (all support rods 96 are equipped with telescopic function), multiple adjusting rods 97 can be moved upward together.

[0070] Once all the adjusting rods 97 have moved to the lower end of the corresponding adjusting plate 99, and the positioning sleeve 2 4 continues to be driven by the force to move the two threaded cylinders 3 and the multiple adjusting plates 99 downwards, the multiple adjusting rods 97 will gradually enter the interior of the adjusting plate 99. At this time, if the center of the pipe to be welded on the positioning sleeve 1 and the center of the pipe to be welded on the positioning sleeve 2 4 are on the same axis, the multiple adjusting rods 97 will also be located exactly at the lower end of the corresponding adjusting plate 99 (e.g., Figure 21 (as shown in the diagram) At this point, by manually or mechanically driving the positioning sleeve 24 to continuously move downwards with the pipe to be welded on it, the two pipes to be welded can be directly and accurately connected.

[0071] If the centers of the pipe to be welded on positioning sleeve 1 and the pipe to be welded on positioning sleeve 2 are not on the same axis, such as when the pipe on positioning sleeve 2 is offset to the left relative to the pipe on positioning sleeve 1, the adjusting rod 97 will contact the left side wall of the corresponding adjusting plate 99. When positioning sleeve 2 is subjected to continuous downward force, due to the position limitation of the multiple adjusting rods 97 by the pressing component 8, the resistance of the adjusting rods 97 to the vertical downward movement of the corresponding adjusting plate 99 will cause the adjusting rods 97 to engage with the corresponding adjusting groove, driving the corresponding adjusting plate 99 to move to the right (e.g., ...). Figure 21 As shown in the direction, during the process of multiple adjusting plates 99 moving to the right under force, the corresponding pipe to be welded can be driven to move to the right through the cooperation of the corresponding spring telescopic tube 610 and the arc-shaped pressing plate 611 until the adjusting rod 97 is directly opposite to the corresponding adjusting plate 99, and the center of the pipe to be welded on the positioning sleeve 1 and the center of the pipe to be welded on the positioning sleeve 2 are directly opposite. In this way, the equipment can automatically and accurately connect the two pipes to be welded, which helps to improve the welding effect of the two pipes in the future.

[0072] Simultaneously, as the two threaded sleeves 91 rotate under force, driving the corresponding support frame 94 and the two adjusting rods 97 to move upward, the corresponding torsion springs 92 will rotate along with them, thus achieving the effect of storing force in the torsion springs 92. When the multiple adjusting rods 97 cooperate with the corresponding adjusting plate 99 to automatically adjust the center position of the two pipes to be welded, and the two pipes to be welded are connected, when the positioning sleeve 2 4 and the two threaded cylinders 3 stop moving downward, the two threaded sleeves 91 can be driven to quickly reverse direction by the elastic force of the two torsion springs 92. At this time, the rotation of the two threaded sleeves 91 can drive the corresponding support frame 94, the two telescopic rods 95, and the two adjusting rods 97 to quickly move downward and reset (e.g., Figure 20 (As shown in the direction), this helps prevent the multiple adjusting rods 97 from obstructing the two pipe joint positions during subsequent welding operations, thus improving the convenience of welding the two pipes to a certain extent.

[0073] Simultaneously, multiple adjusting rods 97 and multiple adjusting plates 99 are used to achieve precise docking of the two pipes to be welded. At this time, the upper ends of the two pushing parts 98 are just in contact with the lower ends of the corresponding arc-shaped support plates 85 (e.g., Figure 20 (as shown in the direction), at this time, by continuously moving the positioning sleeve 2 4 and the corresponding pipe to be welded downwards (assuming that the two pipes to be welded are not yet fully attached, and multiple adjusting rods 97 slide at the middle position of the corresponding adjusting plate 99), the two pushing parts 98 can apply an upward driving force to the corresponding arc-shaped support plate 85. At this time, through the above operating principle, the two upper arc-shaped support plates 85 can cooperate to limit the position of the upper spring telescopic tube 610 (such as...). Figure 18(As shown in the direction), this helps to improve the stability of the position of the upper pipe to be welded relative to the positioning sleeve 2 4, and helps to prevent the two pipes to be welded from shifting relative to the positioning sleeve 1 or positioning sleeve 2 4 due to vibration and other factors during the welding process. Therefore, by cooperating with the pressing component 8 and the two pushing parts 98, the position of the multiple spring telescopic tubes 610 is fixed, which helps to further improve the stability of the position of the two pipes to be welded relative to the corresponding positioning sleeve 1 and positioning sleeve 2 4, that is, helps to further ensure the stability of the relative position of the two pipes after docking, and helps to further ensure the subsequent welding effect of the two pipes.

[0074] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0075] In this invention, when the device is used to connect two pipes, the positioning sleeve 1 and positioning sleeve 2 4 are first manually installed on the two pipes to be welded. Then, the air pump 71 is started and the two rotating shafts 5 are rotated in sequence. When the upper and lower rotating shafts 5 are rotated in sequence under force, the clamping assembly 6 can be used to clamp and position the corresponding pipes to be welded through the cooperation of multiple spring telescopic tubes 610 and multiple arc-shaped pressing plates 611.

[0076] Simultaneously, the operation of the air pump 71 cleans the surface of the corresponding arc-shaped pressing plates 611 as they gradually approach the corresponding pipe to be welded. This helps improve the fit between the arc-shaped pressing plates 611 and the pipe to be welded. After the corresponding spring telescopic tubes 610 drive the corresponding arc-shaped pressing plates 611 to clamp and position the corresponding pipe to be welded, the air pump 71, in conjunction with the air supply component 7, can achieve adsorption and fixation of the corresponding arc-shaped pressing plates 611 on the corresponding pipe to be welded. This helps improve the clamping stability of the multiple spring telescopic tubes 610 and multiple arc-shaped pressing plates 611 on the corresponding pipe to be welded, which helps to improve the subsequent welding effect of the two pipes to be welded to a certain extent.

[0077] After the corresponding multiple arc-shaped pressing plates 611 cooperate to complete the positioning of the corresponding pipes to be welded, the pipes to be welded above are gradually moved closer to the pipes to be welded below by manual or mechanical means (e.g. Figure 1(As shown in the direction), through the cooperation of two threaded cylinders 3, two guide cylinders 2, and pressing assembly 8, the positions of multiple spring telescopic tubes 610 and multiple adjusting rods 97 on positioning sleeve 1 can be limited first. Then, as the upper pipe to be welded continues to move downward, through the cooperation of the adjusting mechanism with multiple adjusting rods 97 and multiple adjusting plates 99, the center position of the two pipes to be welded can be adjusted, which helps to accurately connect the two pipes in the future. After the equipment has adjusted the position of the two pipes to be welded, through the cooperation of two pushing parts 98 and two upper arc-shaped support plates 85, the position of multiple spring telescopic tubes 610 can be limited. This can limit the position of the two pipes to be welded relative to the corresponding positioning sleeve 1 and positioning sleeve 2 4, and ensure the stability of the relative position after the two pipes to be welded are accurately connected, which helps to further improve the subsequent welding effect of the two pipes to be welded.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
