[0031] Please refer to Figure 1 、Figure 2 , mine filling technology is mainly used for the treatment of ore body cavities in mine mining to improve the safety and economic benefits of mine mining

[0032] Common filling materials include concrete, mortar, tailings, etc. These materials can fill the cavities formed during mine mining to prevent the collapse of the ore body. When using pumping filling, for the filling pipeline conveying system, the filling pipeline is generally 6m per root. The conventional pipeline connection method uses flange connection, which has the advantages of fast construction speed and convenient disassembly, but also has disadvantages such as low pressure resistance and easy pipe explosion of flange connection. Especially for the pumping filling system or the pipeline near the bottom of the drill hole, the pipeline flange bears greater pressure and is more likely to cause safety accidents due to pipe explosion, threatening the safety of personnel. The traditional pipeline welding method has problems such as large labor intensity of operators, low welding efficiency, and poor welding quality. Based on this, the present application provides a pipeline butt welding auxiliary device, including a support frame 1 for support and a limit component 2 arranged on the support frame 1;

[0033] The support frame 1 includes a frame body 11. A vertically upward support plate is arranged on one long side of the frame body 11. Two slidably connected connecting bars are arranged outside the support plate. Fixed pulleys 23 and movable pulleys 22 are respectively arranged at both ends of the connecting bar. The movable pulley 22 moves closer to or away from the fixed pulley 23 along the connecting bar, and a pipeline is arranged between the movable pulley 22 and the fixed pulley 23;

[0034] Two through holes are symmetrically arranged on the long side of the frame body 11. A threaded rod 24 is inserted at the through hole. A sliding strip 21 is threadedly connected to the rod body of the threaded rod 24. Both ends of the sliding strip 21 are slidably connected to the bottom of the movable pulley 22 on the connecting bar, and a rotating hand ring 25 is arranged at the other end of the threaded rod 24.

[0035] The main structural part of the support frame 1 is usually made of a strong metal material (such as steel) to provide stable support.

[0036] A vertically upward support plate is arranged on one long side of the frame body 11 to support the connecting bar and the pulley system.

[0037] Two slidably connected connecting bars are installed outside the support plate, allowing the movable pulley 22 to slide along the connecting bar, thereby adjusting the position of the pipeline.

[0038] Fixed pulleys 23 are arranged at both ends of the connecting bar. The fixed pulleys 23 are fixed on the connecting bar to help guide the movable pulley 22.

[0039] The movable pulley 22 slides along the connecting bar and can move closer to or away from the fixed pulley 23. The movable pulley 22 adjusts the butt position of the pipeline through the movement of the pulley system.

[0040] The pipeline arranged between the movable pulley 22 and the fixed pulley 23 needs to be butt-welded, and the length and position of the pipeline can be adjusted by the pulley system for accurate butt-welding.

[0041] The threaded rod 24 inserted through the through hole has threads on its body and is used to connect with the sliding bar 21 .

[0042] The sliding bar 21 is threadedly connected to the threaded rod 24 , and both ends are slidably connected to the bottom of the movable pulley 22 , so that the adjustment of the sliding bar 21 can directly affect the position of the movable pulley 22 .

[0043] A rotating bracelet 25 is provided at the other end of the threaded rod 24 for conveniently rotating the threaded rod 24 , thereby adjusting the position of the sliding bar 21 and further adjusting the movement range of the movable pulley 22 .

[0044] Through the precise adjustment of the pulley system, accurate butt jointing of the pipes can be achieved, reducing welding defects caused by inaccurate butt jointing, thereby improving the overall quality of welding.

[0045] The device reduces the manual operation time in traditional welding methods, and the design of the pulley system makes the pipe docking process smoother and increases the speed of the welding operation.

[0046] Automated or semi-automated docking devices reduce the need for manual adjustment and handling of pipelines, reduce the labor intensity of workers, and reduce physical exertion during operation.

[0047] By improving welding accuracy and reducing manual operations, the risk of accidents caused by poor pipeline docking is reduced and the safety of operations is increased.

[0048] The design of the support frame 1, the pulley system and the threaded rod 24 makes the pipe docking process easier, reduces the complicated manual adjustment steps, and makes the entire welding process more efficient.

[0049] The adjustable pulley system and the threaded rod 24 design enable the device to adapt to pipes of different specifications, thus improving its versatility and flexibility.

[0050] See also Figure 1 , Figure 2 . Figure 3 as well as Figure 4 An end plate 12 and an end plate 2 14 are respectively provided at two ends of the support frame 1 , and both the end plate 12 and the end plate 2 14 are movably connected to the support frame 1 .

[0051] A slide groove 17 is provided in the middle of the top of the end plate 12, and an adjustment component 4 is slidably connected to the inner side of the slide groove 17 for limiting the position of the limited pipeline.

[0052] At the top of the second end plate 14, a motor 15 is installed. On the output shaft of the motor 15, a connecting rod 16 is installed. At the opposite ends of the connecting rod 16 and the adjustment assembly 4, inner diameter clamping assemblies 5 are connected, which are used to restrict the inner side of the pipeline.

[0053] At both ends of the support frame 1, a first end plate 12 and a second end plate 14 are respectively provided. These two end plates are fixed to the support frame 1 by a movable connection method. The first end plate 12 and the second end plate 14 can move within a certain range on the support frame 1. For example, they can be made parallel to the support frame 1 through hinges, or a slide rail structure can be used to make them retracted inside the support frame 1 to adapt to different pipeline sizes and docking requirements.

[0054] In the middle of the top of the first end plate 12, a chute 17 is opened. Inside the chute 17, an adjustment assembly 4 is slidably connected. The settings of the chute 17 and the adjustment assembly 4 enable the adjustment assembly 4 to move back and forth within the chute 17, which is used to restrict and adjust the position of the pipeline. The specific form of the adjustment assembly 4 can be a slider or a component with adjustment threads, allowing precise adjustment of the pipeline position within the chute 17.

[0055] At the top of the second end plate 14, a motor 15 is installed. On the output shaft of the motor 15, a connecting rod 16 is installed. One end of the connecting rod 16 is connected to the output shaft of the motor 15, and the other end is connected to the opposite end of the adjustment assembly 4. This setting allows the motor 15 to drive the connecting rod 16 to rotate or move linearly, thereby adjusting the position of the adjustment assembly 4.

[0056] At the opposite end of the connecting rod 16 and the adjustment assembly 4, an inner diameter clamping assembly 5 is installed, which is used to restrict the inner side of the pipeline. The inner diameter clamping assembly 5 can be an electric clamp or a mechanical clamp, and it fixes the inner diameter of the pipeline by adjusting the clamping force to ensure that the pipeline does not move or deform during the welding process.

[0057] The design of the chute 17 and the adjustment assembly 4 makes it possible to precisely restrict and adjust the position of the pipeline, ensuring accurate alignment of the pipeline during the docking and welding process, thereby improving the welding accuracy.

[0058] The inner diameter clamping assembly 5 can firmly clamp the inner side of the pipeline, preventing the pipeline from moving or deforming during the welding process, enhancing the stability of the pipeline, and ensuring the welding quality.

[0059] The settings of the motor 15 and the connecting rod 16 enable the adjustment process to be automated. The motor 15 drives the connecting rod 16 to adjust the position, reducing the need for manual operation and improving the adjustment efficiency and accuracy.

[0060] The movable connection of the end plates and the design of the chute 17 enable the device to adapt to pipelines of different sizes, enhancing the versatility of the device. The adjustment ability of the inner diameter clamping assembly 5 also enables the device to handle pipelines with various inner diameters.

[0061] See also Figure 3 and Figure 4 The adjustment assembly 4 includes a sliding plate 41 and a docking rod 42 . The docking rod 42 is arranged on one side of the sliding plate 41 , and a push plate 43 is arranged on the other side of the sliding plate 41 .

[0063] One end of the two adjusting rods 54 is respectively combined with the butt joint rod 42 and the connecting rod 16 , and a resisting soft plate 51 is also provided on the outer side of the claw 53 for limiting the inner sides of the two butt joint pipes.

[0064] The sliding plate 41 is used to carry and move the docking rod 42. The movement of the sliding plate 41 can accurately adjust the docking position of the pipeline.

[0065] The docking rod 42 is arranged on one side of the sliding plate 41 for docking with the pipeline. The movement range of the docking rod 42 is matched with the sliding of the sliding plate 41, so as to achieve accurate docking of the pipeline.

[0066] A push plate 43 is disposed on the other side of the sliding plate 41 , and the push plate 43 is used to apply force or assist in adjusting the position of the pipeline, so that the sliding plate 41 can perform the adjustment operation more effectively.

[0067] The inner diameter clamping assembly 5 includes at least two claws 53, which are used to clamp the inner side of the pipe to ensure the stability of the pipe during welding. The middle of each claw 53 is equipped with a bearing 52, so that the claw 53 can rotate or move, providing better clamping force and flexibility.

[0068] A bearing 52 is provided in the middle of the clamping claw 53. The bearing 52 allows the clamping claw 53 to rotate during the clamping process, thereby reducing friction and ensuring a smooth clamping process.

[0069] An adjusting rod 54 is provided in the middle of the bearing 52 for adjusting the clamping force or position of the claw 53. One end of the adjusting rod 54 is combined with the docking rod 42 and the connecting rod 16 so that the adjustment process is coordinated with the docking process.

[0070] The outer side of the clamping claw 53 is provided with a soft contact plate 51, which is designed to limit and support the inner side of the pipe, provide a soft contact surface to protect the inner surface of the pipe, and enhance the clamping force.

[0071] The cooperation of the sliding plate 41 and the docking rod 42 allows the position of the pipe to be adjusted accurately, achieving high-precision pipe docking and ensuring welding quality. The movement of the sliding plate 41 and the auxiliary function of the push plate 43 make the adjustment process more accurate.

[0072] The design of the jaw 53 and the bearing 52 makes the clamping process more stable. The bearing 52 reduces the friction between the jaw 53 and the pipe, ensuring a smooth clamping process and providing good stability.

[0073] The combination of the adjusting rod 54, the docking rod 42, and the connecting rod 16 enables the automation of the adjustment of the clamping force and position, improving the efficiency and consistency of the adjustment process.

[0074] The design of the contact soft board 51 not only provides good clamping force but also protects the inner surface of the pipe, avoiding damage caused by clamping and enhancing the overall quality of pipe docking.

[0075] The bottom of the support frame 1 is provided with support feet 13, and a welding device 3 is arranged at the docking part of the two pipes.

[0076] The support feet 13 are installed at the bottom of the support frame 1 to provide the stability of the device. The support feet 13 can be feet with adjustable height to adapt to different ground conditions and ensure that the support frame 1 does not tilt or shake during operation.

[0077] Generally, strong metal materials (such as steel) or high-strength plastics are used to provide sufficient stability and durability. The bottom of the support feet 13 can be equipped with anti-slip pads to increase the friction with the ground and prevent the device from sliding during operation.

[0078] A welding device 3 is arranged at the docking part of the two pipes, responsible for completing the welding task of the pipes. The welding device 3 can include an automatic welding machine, a welding head, a welding power supply, and a control system, etc.

[0079] The welding device 3 may include an automatic welding machine that can automatically complete the welding work according to preset parameters. The automatic welding machine usually has high welding precision and consistency, which can improve the welding quality.

[0080] The welding head can be adjusted according to the diameter of the pipe and the welding requirements to ensure full coverage of the welding and good welding joints.

[0081] The power supply of the welding device 3 provides the necessary current and voltage, and the control system is used to set and adjust the welding parameters, monitor the welding process, and ensure the welding quality.

[0082] The support feet 13 provide the necessary stability to prevent the support frame 1 from tilting or shaking during operation. This stability ensures the position accuracy during pipe docking and welding, reducing the errors that may occur during the welding process.

[0083] Setting a welding device 3 at the pipe docking location can provide precise welding operations. In particular, the application of an automatic welding machine can automatically complete welding according to preset parameters, improving the precision and consistency of welding.
