Description

Technical Field

[0001] This invention relates to the field of pipeline construction technology, and in particular to a pipeline assembly welding adjustment device and adjustment method. Background Technology

[0002] Pipeline assembly welding is a crucial process in pipeline construction, widely used in pipeline projects in industries such as petroleum, natural gas, chemical, and municipal water supply. During pipeline assembly welding, the ends of two or more pipes need to be precisely joined to ensure weld quality and the overall straightness and sealing of the pipeline. Traditional pipeline assembly methods mainly rely on manual hoisting, visual alignment, and manual adjustments, which are cumbersome and highly dependent on the experience of the operators. With the continuous expansion of pipeline projects and the increasing demands for construction precision, various auxiliary devices for pipeline assembly are gradually being applied to improve assembly efficiency and connection accuracy.

[0003] Chinese Patent Publication No. CN122231572A discloses a pipe assembly device and a pipe assembly method. The pipe assembly device is used for assembling straight pipes and elbows. The device includes a positioning frame, a clamping mechanism, a clamping auxiliary mechanism, and a locking mechanism. The clamping mechanism is fixed to the positioning frame and provides a first positioning opening. The locking mechanism includes a fixing member and an adjusting member. The fixing member is fixed to the positioning frame and has a guide portion. The adjusting member and the guide portion cooperate to allow the adjusting member to move only in a first direction. The clamping auxiliary mechanism is connected to the adjusting member and provides a second positioning opening. The first and second positioning openings are opposite to each other to clamp the straight pipe, allowing it to move only in a second direction perpendicular to the first direction.

[0004] However, the aforementioned pipe assembly and adjustment devices still have the following technical problems in practical applications: On the one hand, the clamping mechanisms mostly adopt rigid clamping methods, which can easily cause indentations or damage to the pipe surface and have poor adaptability to pipes of different diameters; on the other hand, the devices lack a real-time detection and feedback mechanism for the alignment status of the pipes, making it impossible to automatically determine whether the two pipes are in an aligned state during the assembly process, and it is also difficult to effectively identify abnormalities such as bending deformation or foreign matter adhering to the surface of the pipes. In addition, when there are foreign objects at the contact point between the clamping wheels and the pipes, there is a lack of effective online cleaning methods, which affects the clamping stability and alignment accuracy, thereby reducing the quality and efficiency of pipe assembly welding. Summary of the Invention

[0005] The purpose of this invention is to provide a pipe assembly welding adjustment device and adjustment method to solve the problems mentioned in the background art.

[0023] This invention also provides a method for adjusting a pipe assembly welding adjustment device, comprising the following steps:

[0024] S1. By sliding the electromagnetic slider along the electromagnetic slide groove, the clamping system is moved horizontally along the base to adjust the lateral position of the clamping system.

[0025] S2. Start the linear drive device to drive the clamping slider to slide linearly along one side of the fixed base plate, so that the clamping slider contacts and clamps the pipes to be assembled from the left and right sides.

[0026] S3. Start the hydraulic push rod to drive the arc-shaped fixed plate to move horizontally.

[0027] The technical effects and advantages of this invention are as follows:

[0028] 1. This invention uses an electromagnetic slider to slide along an electromagnetic groove to drive the clamping system to move laterally. In conjunction with a linear drive device, the clamping slider is driven to radially clamp the pipe. The hydraulic push rod drives the contact plate to perform auxiliary positioning on the side of the pipe. This achieves multi-dimensional automated adjustment during the pipe assembly process, improving the pipe positioning accuracy and adjustment efficiency.

[0029] 2. This invention utilizes a piston slide plate and flexible membrane driven by a miniature electromagnetic pusher inside the clamping wheel. This allows the clamping wheel to adaptively adjust the clamping force and contact stiffness according to the pipe's outer diameter, avoiding damage to the pipe surface caused by rigid clamping. Simultaneously, a pressure sensor monitors the contact pressure between the pipe and the placement pad in real time, and a rotary drive device rotates the clamping wheel in the same direction, enabling automatic detection and adjustment of the pipe's axial alignment. Furthermore, by observing the change in the compression of the return spring as the contact plate moves along the pipe surface, pipe bending defects can be effectively identified and the bending location precisely located. When foreign objects are present at the contact point between the clamping wheel and the pipe, the flexible membrane protrudes to increase friction and, in conjunction with the counter-rotation of the clamping wheel, performs wiping and cleaning. The concave interior of the flexible membrane forms a accommodating space, which, combined with intermittent rotation, allows for the collection and discharge of impurities and debris, significantly improving the quality stability of the pipe assembly welding and the environmental adaptability of the equipment.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] This invention provides, for example Figures 1 to 9 The pipe assembly welding adjustment device shown includes a support mechanism 1, an adjustment unit 2, and a clamping system 3. The adjustment unit 2 and the clamping system 3 are respectively located above the support mechanism 1.

The number of linear drive devices 304 and clamping sliders 305 is at least two. The two linear drive devices 304 and clamping sliders 305 are symmetrically arranged on the left and right sides of the fixed base plate 302. The two linear drive devices 304 cooperate with the clamping sliders 305 to contact and clamp the left and right sides of the pipe 306 to be assembled.

[0045] A load-bearing pad 303 is provided on the top of the fixed base plate 302. The pipe 306 to be assembled is located above the load-bearing pad 303. The load-bearing pad 303 is made of flexible material. The load-bearing pad 303 is used to contact the bottom of the pipe 306 to be assembled and provide friction to prevent the pipe from slipping and falling off during the assembly process. An extension plate 301 is provided on one side of the fixed base plate 302. The extension plate 301 is used to increase the contact area between the fixed base plate 302 and the round pipe. Together with the load-bearing pad 303, it not only increases the friction with the bottom of the pipe, but also increases the contact area with the bottom of the pipe. The pipe 306 to be assembled is placed on top of the load-bearing pad 303.

[0046] The upper part of the clamping slider 305 is provided with a mounting base. The clamping slider 305 is rotatably mounted with a clamping wheel 307 through the mounting base. The surface of the clamping wheel 307 contacts and clamps the outer surface of the pipe 306 to be assembled. The number of linear drive devices 304, clamping sliders 305, mounting bases and clamping wheels 307 is set to multiple. The multiple linear drive devices 304, clamping sliders 305, mounting bases and clamping wheels 307 are symmetrically arranged on the left and right sides of the clamping slider 305. The multiple linear drive devices 304 cooperate with the clamping sliders 305 and clamping wheels 307 to clamp and fix the left and right sides of the pipe 306 to be assembled. A rotation drive device is provided on one side of the clamping wheel 307. The rotation drive device can control the clamping wheel 307 to rotate inside the mounting base.

[0047] The clamping wheel 307 includes an outer wheel frame 312. The outer wheel frame 312 has multiple through holes on its outer side, arranged in a circumferential array on the outer circumferential surface of the outer wheel frame 312. A flexible membrane 308 is provided on the outer surface of the outer wheel frame 312 near the through holes. A piston mechanism is provided inside the outer wheel frame 312. The piston mechanism includes a micro electromagnetic push rod 309 and a piston slide plate 310. The output end of the micro electromagnetic push rod 309 is connected to one side of the piston slide plate 310. A piston tube 311 is provided inside the outer wheel frame 312. The piston slide plate 310 and the micro electromagnetic push rod 309 are both located inside the piston tube 311. The micro electromagnetic push rod 309 controls the piston slide plate 310 to slide along the inner wall of the piston tube 311.

[0048] The adjustment unit 2 is located above the base 102 and includes at least two adjustment rods 201, which are longitudinally symmetrically arranged above the base 102. Each adjustment rod 201 has a mounting plate at its top end, and a hydraulic push rod 202 is located on one side of the mounting plate. An arc-shaped fixing plate 204 is located at the output end of the hydraulic push rod 202. A fixing plate 205 is located on the surface of the arc-shaped fixing plate 204. A limiting rod 206 is located inside the fixing plate 205, and a contact plate 208 is located at the end of the limiting rod 206. A return spring 207 is located on the surface of the contact plate 208, between the contact plate 208 and the fixing plate 205, with the fixing plate 205 facing the side of the return spring 207. A pressure detection device is provided, which is used to detect the compression data of the return spring 207. The outer surface of the limit rod 206 is linearly slidably connected to the inside of the mounting plate. The bottom of the contact plate 208 is set as an arc surface, and the bottom of the contact plate 208 abuts against the top of the pipe 306 to be assembled. The adjusting rod 201 adopts a two-section telescopic structure, including a top section and a bottom section. The outer surface of the top section is slidably inserted into the bottom section to form a telescopic sliding fit. An electric telescopic rod 209 is provided inside the bottom section. The output end of the electric telescopic rod 209 is fixedly connected to the bottom of the top section. The electric telescopic rod 209 drives the top section to rise and fall relative to the bottom section to adjust the longitudinal height of the contact plate 208 by extending or retracting.

[0049] The top of the arc-shaped fixed plate 204 is provided with a limiting slider, and a top plate 203 is provided above the limiting slider. The outer side of the limiting slider is linearly slidably connected to the inside of the top plate 203. The left and right sides of the top plate 203 are connected to the root surface of the hydraulic push rod 202. When the hydraulic push rod 202 controls the arc-shaped fixed plate 204 to move horizontally, the limiting slider slides horizontally along the bottom surface of the top plate 203.

[0050] First, during use, the pipe 306 to be assembled is hoisted and placed above the load-bearing pad 303, so that the bottom of the pipe contacts the load-bearing pad 303 made of flexible material. The friction of the load-bearing pad 303 initially prevents the pipe from slipping. Then, the electromagnetic slider 105 in the electromagnetic slide 104 is activated, which drives the clamping system 3 to move horizontally along the electromagnetic slide 104. The distance between the two clamping systems 3 is adjusted to adapt to the length of the pipe.

[0051] Next, the linear drive device 304 is activated, extending its output end and pushing the clamping slider 305 to slide linearly along one side of the fixed base plate 302 toward the pipeline until the flexible membrane 308 on the outer wheel frame 312 of the clamping wheel 307 mounted on the mounting base on the upper part of the clamping slider 305 contacts the outer surface of the pipeline. At this time, the linear drive device 304 is further fine-tuned so that the multiple clamping wheels 307 symmetrically arranged on the left and right sides apply uniform clamping force from both sides of the pipeline, completing the radial positioning and clamping of the pipeline.

[0052] During clamping, if further adjustment of the pipe height or angle is required, the hydraulic push rod 202 in adjustment unit 2 is activated. The hydraulic push rod 202 pushes the arc-shaped fixed plate 204 to move horizontally. At the same time, the limiting slider at the top of the arc-shaped fixed plate 204 slides along the bottom surface of the top plate 203 for guidance. The arc-shaped fixed plate 204 drives the limiting rod 206 and the contact plate 208 to move synchronously through the fixed plate 205. The contact plate 208 compresses the return spring 207, causing the contact plate 208 to abut against the side of the pipe to achieve auxiliary positioning and fine adjustment. Secondly, the height of the contact plate 208 can be adjusted by extending or retracting the electric telescopic rod 209. In addition, after the clamping wheel 307 clamps the pipe... The micro electromagnetic push rod 309 inside the outer wheel frame 312 can be activated as needed. The micro electromagnetic push rod 309 drives the piston slide plate 310 to slide along the inner wall of the piston tube 311, changing the air pressure or medium state inside the piston tube 311, thereby adjusting the bonding stiffness or buffering performance of the flexible membrane 308, ensuring that pipes of different diameters can be stably clamped without damaging the surface. At the same time, during the clamping process of the pipes 306 to be assembled, the welding ends of the two pipes 306 to be assembled are located above the placement platform 107 and in close contact with the surface of the placement pad 106 above the placement platform 107. Thus, the adjustment and fixing work before the pipe assembly welding is completed.

[0053] It should be noted that while clamping and positioning the pipes 306 to be assembled, the welding ends of both pipes 306 are positioned above the placement platform 107 and in close contact with the surface of the placement pad 106 above the placement platform 107. Pressure sensors installed inside the placement pad 106 begin to collect pressure data between the two pipes and the placement pad 106 in real time and transmit the data to the control system. By comparing the readings of the two pressure sensors, the control system can determine whether the two pipes are aligned: if the pressure values ​​on both sides are equal or the difference is within a preset allowable range, the axes of the two pipes are considered aligned; if there is a deviation, the alignment adjustment procedure is triggered.

[0054] During testing, the miniature electromagnetic push rod 309 inside the clamping wheel 307 is activated, driving the piston slide plate 310 to slide along the inner wall of the piston tube 311, causing the flexible membrane 308 to bulge outward, increasing the friction between the clamping wheel 307 and the pipe surface. Simultaneously, the rotary drive device (not shown in the figure but implicitly contained in the structure of the clamping wheel 307) is activated, driving the clamping wheels 307 on both sides to rotate in the same direction. The increased friction drives the pipes to be assembled 306 to rotate around their own axis. During the rotation, the pressure sensor continuously monitors the change in contact pressure between the two pipes and the placement pad 106. The control system compares the pressure data on both sides in real time, which allows the alignment of the outer diameters of the two pipes to be assembled 306 to be checked until the pressure on both sides tends to be consistent, indicating that the two pipes have completed the alignment. After the alignment is completed, the rotary drive device is stopped, and the miniature electromagnetic push rod 309 is retracted, the flexible membrane 308 returns to flatness, and the clamping wheel 307 remains in a static clamping state. Welding operations can then be performed.

[0055] The shaft adjustment operation is divided into the following two situations depending on the actual situation:

[0056] Firstly, for the detection and positioning of pipe 306 to be assembled, which is not perpendicular (pipe bending), the hydraulic push rod 202 is activated, driving the contact plate 208 to move horizontally along the outer surface of pipe 306. During the movement, the contact plate 208 maintains contact with the pipe surface, and the morphological characteristics of the pipe surface are fed back in real time through the change in the compression of the return spring 207. When the contact plate 208 passes through the bending part of the pipe, the compression of the return spring 207 will change abruptly, showing a sudden increase or decrease in compression. Based on this, it is determined that the pipe 306 to be assembled has a non-perpendicularity defect and cannot meet the welding requirements. The system then issues an alarm signal and controls the contact plate 208 to stop moving and hover at the bending area to accurately locate the specific location of the pipe bend, facilitating subsequent processing or marking by the staff.

[0057] Secondly, if it is determined that there are foreign objects at the contact point between the clamping wheel 307 and the outer surface of the pipe, the following cleaning steps shall be performed:

[0058] First, the miniature electromagnetic push rod 309 inside the outer wheel frame 312 drives the piston slide plate 310 to slide along the piston tube 311, causing the flexible membrane 308 to bulge outward to increase the friction between the clamping wheel 307 and the pipe surface. Simultaneously, the electric telescopic rod 209 inside the adjusting rod 201 controls the longitudinal height of the contact plate 208, ensuring close contact between the contact plate 208 and the upper surface of the pipe 306 to be assembled. This creates a longitudinal clamping force between the supporting pad 303 and the contact plate 208, making the friction force of this longitudinal clamping force much greater than the friction force generated between the clamping wheel 307 and the outer surface of the pipe. Then, a rotary drive device drives the two clamping wheels 307 to rotate synchronously in opposite directions, achieving cleaning of the clamping points between the two clamping wheels 307 and the outer surface of the pipe. After cleaning, the contact plate 208 is controlled to return to its initial contact state with the upper outer surface of the pipe (i.e., the return spring 207 is at its initial fixed compression).

[0059] Subsequently, the miniature electromagnetic push rod 309 inside one of the outer wheel frames 312 is retracted, driving the piston slide plate 310 to slide along the inside of the piston tube 311, creating a negative pressure state inside the outer wheel frame 312. The flexible membrane 308 then recesses inward along the through hole on the surface of the outer wheel frame 312, thereby forming an inwardly recessed accommodating space on the surface of the clamping wheel 307. Next, the other clamping wheel 307 is controlled to rotate in any direction in conjunction with its rotation drive device, causing the pipe 306 to be assembled to rotate along with the rotation of the clamping wheel 307. During this process, impurities and debris remaining on the outer surface of the pipe after wiping gradually enter the aforementioned recessed accommodating space. To prevent all impurities and debris from accumulating in the same recessed accommodating space, the rotation drive device on the clamping wheel 307 with the recessed accommodating space is controlled to rotate intermittently. With the intermittent rotation of the clamping wheel 307, the impurities and debris that have entered the recessed accommodating space are gradually carried out and discharged to the outside, thereby achieving a thorough cleaning effect.

[0060] This invention also provides a method for adjusting a pipe assembly welding adjustment device, comprising the following steps:

[0061] S1. The electromagnetic slider 105 slides along the electromagnetic slide groove 104, driving the clamping system 3 to move horizontally along the base 102, thereby adjusting the lateral position of the clamping system 3.

[0062] S2. Start the linear drive device 304, drive the clamping slider 305 to slide linearly along one side surface of the fixed base plate 302, so that the clamping slider 305 contacts and clamps the pipe 306 to be assembled from the left and right sides.

[0063] S3. Start the hydraulic push rod 202 to drive the arc-shaped fixed plate 204 to move horizontally. The arc-shaped fixed plate 204 drives the limit rod 206 and the contact plate 208 to move synchronously through the fixed plate 205, so that the contact plate 208 abuts against the side of the receiving assembly pipe 306 to complete the adjustment and positioning of the pipe assembly.

[0064] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
