Description

Technical Field

[0001] This invention relates to the technical field of pipeline assembly welding and joint repair, and is a comprehensive operation platform for laying land pipelines. Background Technology

[0002] Currently, the processing of pipe ends for land pipelines generally adopts the traditional construction process of separate, step-by-step operations. A complete single-end pipe end forming process requires three independent steps: pipe assembly, pipe end welding, and weld repair. Each step requires dedicated construction equipment and specialized personnel to complete in concert. The specific construction process is as follows: First, dedicated pipe assembly equipment is used to precisely align, level, correct, and fix adjacent pipe sections to be welded, strictly calibrating key parameters such as pipe section coaxiality, joint gap, and misalignment to ensure that the pipe section assembly accuracy meets the construction specifications. After the pipe section assembly passes inspection, dedicated welding equipment is used, and personnel perform welding operations on the joined pipe ends to complete the pipe end weld formation. After the pipe end welding is completed and the weld quality inspection is passed, dedicated repair equipment is deployed to perform anti-corrosion and sealing repair treatment on the welded pipe end and surrounding area to prevent corrosion and leakage. Only then is the entire process of processing a single pipe end complete.

[0003] The aforementioned traditional split-type construction process has many inherent defects in practical engineering applications, resulting in extremely low levels of intelligence and integration in the overall construction mode. Firstly, the construction equipment configuration is complex and redundant. Each of the three processes requires independent assembly, welding, and jointing equipment. Frequent equipment entry, transfer, debugging, switching, and storage during construction significantly increase the material costs of equipment procurement, maintenance, and transfer, while also occupying a large amount of construction space and making equipment management extremely difficult. Secondly, the work process is cumbersome and fragmented. Each process operates independently, requiring sequential quality acceptance, personnel handover, and equipment replacement between processes. This results in poor work continuity, numerous waiting periods, and gaps in coordination, making the overall work process complex and redundant. This significantly extends the processing cycle of a single pipe joint, leading to a substantial increase in the overall project construction period. Summary of the Invention

[0004] This invention provides a comprehensive operation platform for laying land pipelines, which overcomes the shortcomings of the prior art and can effectively solve the problems of time-consuming and labor-intensive, low construction efficiency, and safety hazards caused by the independent existence of each process in the existing pipeline welding process.

Detailed Implementation

[0048] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0049] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as front, back, top, bottom, left, right, etc. The positional relationships are determined based on the layout direction of the attached diagram in the instruction manual.

[0050] The present invention will be further described below with reference to embodiments and accompanying drawings: As attached Figure 1-33As shown, the integrated land pipeline laying operation platform includes a tracked chassis 3 and an operation platform 4 mounted on top of the tracked chassis 3. From the middle to the left of the upper side of the operation platform 4, a measuring device 7, a welding module 8, a clamping device 9, and a jointing module 10 are sequentially arranged. On the right side of the upper side of the operation platform 4, a hoisting module 5 and an assembly module 6 are arranged. The hoisting module 5 is used to hoist the pipeline 2 to be welded, the measuring device 7 is used to measure the alignment data of the two pipe ends, and the assembly module 6 is used to adjust the relative positions of the two pipelines to align them. The assembly module 6 consists of two sets of identical sub-modules spaced apart on the left and right sides. The system consists of 11 components. Sub-module 11 is arranged along the pipeline axis. Sub-module 11 includes an axial moving device 11.1. The axial moving device 11.1 includes an axial moving frame 11.1.1. Two axial moving rollers 11.1.2 are rotatably mounted on the axial moving frame 11.1.1. The extended lines of the axes of the two axial moving rollers 11.1.2 are V-shaped. The axes of the axial moving rollers 11.1.2 are perpendicular to the pipeline axis, supporting the axial movement of the pipeline. An axial moving motor 11.1.3 is connected to the end of the axial moving rollers 11.1.2.

[0051] The hoisting module 5 is used to lift the pipe 2 to be welded and place it on the assembly module 6. The assembly module 6 is used to support the pipe 2 to be welded and to assemble the pipe ends of the pipe 2 to be welded with the pipe 1 already welded, including aligning the pipe axis and the major and minor axes of the two pipe ends. The measuring device 7 is used to measure the misalignment and major and minor axes of the pipe ends and to feed the data back to the assembly module 6 in real time as the initial parameters for fine-tuning of the assembly module 6. The welding module 8 is located in the middle of the working platform 4 and is used to weld the pipe ends to be welded. The clamping device 9 is used to clamp the pipe 1 already welded and to ensure that the axis of the pipe 1 is straight. The joint repair module 10 is located at the tail of the working platform 4 and is used to repair the joints of the already welded pipe ends. The axial moving roller 11.1.2 is arranged perpendicular to the pipe axis. The axial moving motor 11.1.3 drives the axial moving roller 11.1.2 to move the pipe 2 to be welded axially, so as to achieve the contact of the pipe ends.

[0052] This application integrates hoisting, pipe assembly, pipe welding, and weld repair functions into one unit, enabling the entire pipe joint construction process to be completed in one go. This not only significantly simplifies equipment configuration and process connection links, shortens the operation cycle, and improves construction efficiency, but also reduces labor input, equipment transportation, and management costs, effectively lowering the overall project cost. At the same time, relying on integrated positioning and automated operation, it improves the stability of pipe joint assembly accuracy, welding quality, and repair effect, reduces human operation errors and high-risk on-site operation links, significantly reduces construction safety risks, and is more adaptable to the needs of efficient, safe, and low-cost large-scale construction of long-distance land pipeline projects. It solves many drawbacks of traditional split construction in terms of equipment, process, quality, safety, and cost.

[0053] The aforementioned integrated operation platform for laying land pipelines can be further optimized and / or improved according to actual needs: As attached Figure 12-16 As shown, submodule 11 also includes a fine-tuning device 11.2. The fine-tuning device 11.2 is located on the left side of the axial movement device 11.1, and a transverse movement guide rail 4.3 is located on the upper right side of the work platform 4. The fine-tuning device 11.2 is slidably mounted on the transverse movement guide rail 4.3 to adjust the front-to-back and height positions of the pipe. The fine-tuning device 11.2 includes a fine-tuning frame 11.2.1, within which two axially rotating rollers 11.2.2 are rotatably mounted at a distance from front to back. The axis of the axially rotating rollers 11.2.2 is parallel to the pipe axis. 1.2.2 An axial rotation motor 11.2.3 is connected to the end. Two wedges 11.2.4 are installed at intervals on the lower side of the fine-tuning frame 11.2.1. Each wedge 11.2.4 has two threaded holes spaced apart, with opposite thread directions. Long ball screws 11.2.5 are installed in the two sets of adjacent threaded holes on both wedges 11.2.4. The front and rear parts of the long ball screws 11.2.5 are respectively a left-hand thread 11.2.5.1 and a right-hand thread 11.2.5. .2. And it matches the threaded hole. The end of the long ball screw 11.2.5 is connected to a lifting motor 11.2.6. The lower side of each of the two wedges 11.2.4 is equipped with a transverse moving slider 11.2.7. The lower side of the transverse moving slider 11.2.7 is mounted on the transverse moving guide rail 4.3. The fine-tuning frame 11.2.1 has vertical guide rails 11.2.8 on the outer front and outer rear sides. The fine-tuning frame 11.2.1 moves up and down along the vertical guide rails 11.2.8. The two ends of the long ball screw 11.2.5 pass through the two sets of vertical guide rails 11.2.8 respectively and are connected to the threaded hole. An interlocking nut 11.2.12 is externally installed. A long ball screw step 11.2.11 is provided near the interlocking nut 11.2.12 on the long ball screw 11.2.5. A vertical guide rail 11.2.8 is fixed between the long ball screw step 11.2.11 and the interlocking nut 11.2.12. A short ball screw 11.2.9 is installed on one of the vertical guide rails 11.2.8. A fixed motor 11.2.10 is connected to the end of the short ball screw 11.2.9. The lower side of the fine-tuning frame 11.2.1 is installed on the horizontal moving guide rail 4.3.

[0054] The axis of the axially rotating roller 11.2.2 is parallel to the axis of the pipe and is used to contact and support the pipe 2 to be welded. The axially rotating motor 11.2.3 can drive the axially rotating roller 11.2.2 to rotate. Synchronously driving all the axially rotating rollers 11.2.2 to rotate can drive the pipe 2 to be welded to rotate axially, so that the major and minor axes of the pipe 2 to be welded are aligned with the corresponding major and minor axes of the pipe 1 already welded. The lifting motor 11.2.6 can drive the two long ball screws 11.2.5 to rotate, which further drives a pair of wedges with opposite threaded holes 11.2.4 to move closer or further away, which further drives the fine-tuning frame 11.2.1 to move up and down, realizing the up and down fine-tuning of the fine-tuning device 11.2. A pair of vertical guide rails 11 2.8 The fine-tuning frame 11.2.1 is restricted at both ends, allowing it to move only up and down. A pair of vertical guide rails 11.2.8 are fixed between the long ball screw step 11.2.11 and the interlocking nut 11.2.12, ensuring that the fine-tuning frame 11.2.1 is restricted in the lateral direction at both ends of the pair of vertical guide rails 11.2.8. The fixed motor 11.2.10 is fixed on the working platform 4. Driving the fixed motor 11.2.10 can drive the short ball screw 11.2.9 to rotate, which in turn drives the vertical guide rails 11.2.8 to move back and forth, causing the fine-tuning device 11.2 as a whole to move back and forth on the lateral moving guide rail 4.3, thus realizing the back and forth fine-tuning of the fine-tuning device 11.2.

[0055] When all lifting motors 11.2.6 are driven synchronously so that the height of the axially rotating roller 11.2.2 is lower than that of the axially moving roller 11.1.2, the pipe to be welded 2 is only in contact with the axially moving roller 11.1.2 and not with the axially rotating roller 11.2.2. That is, the pipe to be welded 2 is only supported by the axial moving device 11.1. In this working state, the axially moving motor 11.1.3 is driven synchronously to move the pipe to be welded axially, so as to achieve the fitting of the two ends of the pipe; the lifting motors 11.2.6 are driven synchronously to move the pipe to be welded axially. 1.2.6 When the height of the axially rotating roller 11.2.2 is higher than that of the axially moving roller 11.1.2, the pipe to be welded 2 is only in contact with the axially rotating roller 11.2.2 and not with the axially moving roller 11.1.2. That is, the pipe to be welded 2 is only supported by all the fine-tuning devices 11.2. In this working state, the synchronously driven lifting motor 11.2.6 or the fixed motor 11.2.10 can make the pipe to be welded 2 finely adjusted up and down and back and forth, so as to realize the fine-tuning and pairing of the pipe to be welded 2 and the welded pipe 1.

[0056] As attached Figure 17-25As shown, the measuring device 7 includes a measuring box 7.1. An axial moving slider 7.2 is installed at the bottom of the measuring box 7.1. An intermediate axial moving guide rail 4.1 is provided on the upper side of the middle part of the working platform 4. The axial moving slider 7.2 is slidably installed on the intermediate axial moving guide rail 4.1. A fixed frame 7.3 is provided inside the measuring box 7.1. A large gear shaft 7.9 is installed on the fixed frame 7.3. A rotating frame 7.5 is rotatably installed on the outside of the large gear shaft 7.9. An annular groove with an opening to the right is provided on the right side of the rotating frame 7.5. The large gear shaft 7.9 is located in the groove. A large gear 7.4 is provided on the outer ring of the rotating frame 7.5. A large gear cover plate 7.10 is installed on the fixed frame 7.3 at the position outside the large gear 7.4. Two sets of laser rangefinders 7.8 are symmetrically arranged on the rotating frame 7.5. A small gear 7.6 is provided on the fixed frame 7.3. The small gear 7.6 meshes with the large gear 7.4. The small gear 7.6 is connected to a rotary motor 7.7.

[0057] Reference Figures 22-24 As shown, the laser rangefinder 7.8 is arranged at 180° to achieve polarization correction. Assuming the actual center of the circle around which the laser rangefinder 7.8 revolves is O, and the theoretical center (the actual center of the pipe opening) is O', then... Figure 22 Using the actual center of the circle as the center of the laser measuring instrument 7.8, and establishing a coordinate system with the measuring directions of the laser rangefinders 7.8 at both ends as the X-axis and the perpendicular direction as the Y-axis, the final center data obtained from the actual measurement will deviate from the theoretical center data by a vector OO' (e). In this case, the actual data measured by the left laser rangefinder 7.8 will be larger than the theoretical data, with the deviation component in the X-direction being e. x However, the actual data measured by the laser rangefinder 7.8 on the right side is smaller than the theoretical data, with a deviation component of -e in the X direction. x The deviation e in the X direction can be eliminated by summing the two. x Meanwhile, considering the large diameter of the pipe opening being measured, the deviation e caused by the vector OO' in the direction perpendicular to the direction measured by the laser rangefinder (Y direction) y The impact on the actual measurement results is negligible.

[0058] Reference Figure 25 As shown, when the rotating frame 7.5 rotates, the two pairs of laser rangefinders 7.8 will also rotate around the fixed rotation axis to measure. One pair of laser rangefinders 7.8 can measure the distance from the outer edge of the pipe opening of the pipe to be welded 2 to the laser rangefinder 7.8, and the other pair of laser rangefinders 7.8 can measure the distance from the outer edge of the pipe opening of the welded pipe 1 to the laser rangefinder 7.8. By integrating and processing all the data measured by the two pairs, the phase of the major and minor axes of the pipe openings at both ends can be obtained.

[0059] As attached Figure 26 , 27As shown, the welding module includes a welding box 8.1, and an axial moving slider 8.2 of the welding module is installed on the lower side of the welding box 8.1. The axial moving slider 8.2 of the welding module is slidably installed on the intermediate axial moving guide rail 4.1. An automatic welding machine 8.3 is installed inside the welding box 8.1.

[0060] The welding module axial movement slider 8.2 and the measuring device axial movement slider 7.2 are mounted on the same working platform axial movement guide rail 4.1. Their function is to move the welding module 8 above the assembled pipe opening for welding operations. The automatic welding machine 8.3 is used to automatically weld the pipe opening to be welded.

[0061] As attached Figure 28-32 As shown, the patching module 10 includes a sandblasting device 10.1, a painting device 10.2, a medium frequency heating device 10.3, and a hot winding device 10.4 arranged sequentially from left to right. The upper left side of the working platform 4 is provided with a tail axial moving guide rail 4.2, and the lower side of the patching module 10 is slidably mounted on the tail axial moving guide rail 4.2.

[0062] The four devices are installed on the axial moving guide rail 4.2 at the tail of the work platform 4 according to the patching process.

[0063] As attached Figure 7-9 As shown, the clamping device 9 consists of three sets arranged at left and right intervals, used to clamp the welded pipe 1. The clamping device 9 includes a lower frame 9.1. The upper end of one side of the lower frame 9.1 is connected to the upper frame 9.2 through a rotating joint 9.4. The upper ends of the other side of the upper frame 9.2 and the other side of the lower frame 9.1 can be fixedly clamped by bolts passing through bolt holes 9.5. Clamping rollers 9.3 are rotatably installed in both the upper frame 9.2 and the lower frame 9.1.

[0064] During the initial operation, the upper frame 9.2 needs to be opened and the welded pipe 1 placed on the lower frame 9.1, supported by the clamping rollers 9.3 on the lower frame 9.1. Then, the upper frame 9.2 is closed, and the welded pipe 1 is fixedly clamped by bolts passing through the bolt holes 9.5 of the upper frame 9.2 and the lower frame 9.1. The clamping rollers 9.3 of the upper frame also contact the welded pipe 1 to prevent the welded pipe 1 from being misaligned. After the clamping device 9 is closed and fixed, all subsequent pipe opening operations do not need to be opened again. Simply move the moving work platform 4 forward to allow the welded pipe 1 to move axially within the clamping device 9.

[0065] As attached Figure 6 As shown, the hoisting module 5 includes a rotating chassis 5.1, a swing arm 5.2 is mounted on the upper end of the rotating chassis 5.1, and a special gripper 5.3 is mounted on the end of the swing arm 5.2.

[0066] The rotating chassis 5.1 and the swing arm 5.2 move to the pipe 2 to be welded, and the special gripper 5.3 picks it up and places it on the assembly module 6.

[0067] As attached Figure 4 As shown, a steering rotary joint 3.1 is provided on the upper side of the tracked chassis 3. A tilting rotary joint 3.2 is hinged on the upper side of the steering rotary joint 3.1. The steering rotary joint 3.1 can rotate around the vertical direction, and the tilting rotary joint 3.2 has its axis in the longitudinal direction and can rotate left and right.

[0068] The steering joint 3.1 and the tilting joint 3.2 enable the working platform 4 to achieve a certain degree of pitch and sway, which facilitates pipe alignment and platform operation.

[0069] Reference Figures 29-33 As shown, after the welding operation of one pipe joint is completed, the tracked chassis 3 drives the work platform 4 to move forward to the next pipe 2.1 to be welded. At this time, the previously welded pipe joint 1.1, i.e., the interface between the pipe 2 to be welded and the welded pipe 1, is located at the rear of the work platform 4. The joint repair module 10 is moved, and each joint repair device is moved to the welded pipe joint 1.1 for construction according to the joint repair procedure, and finally the joint repair operation is completed. At the same time, the land pipeline laying integrated work platform 4 performs the assembly operation of the next pipe 2.1 to be welded.

[0070] The above technical features constitute various embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
