Description

Technical Field

[0001] The invention relates to the technical field of pipeline installation devices, and in particular to an installation structure for a gas pipeline. Background Art

[0002] Gas pipeline refers to gas transported by pipeline. It is an important infrastructure for public utilities or civil use within cities or towns. Gas pipelines can be divided into detailed categories according to their purpose, laying method and gas transmission pressure. In terms of use, they are mainly divided into long-distance gas pipelines and urban gas pipelines. Long-distance gas pipelines are mainly used to transport natural gas produced in natural gas fields far away from cities to distant urban users over long distances, while urban gas pipelines mainly serve the gas supply within cities. According to different materials, gas pipelines can be divided into steel pipes, PE (polyethylene) pipes, etc. Among them, gas pipelines with a design pressure greater than 0.1MPa belong to pressure pipelines in the category of special equipment. These pipelines and their ancillary facilities together constitute an important part of the gas supply system, providing the necessary energy guarantee for the normal operation of the city. Gas pipeline welding is a key link in the gas pipeline installation process, which is directly related to the safety and reliability of the pipeline system. Common ones include gas welding, arc welding, contact welding, etc. The specific selection of welding method needs to be considered comprehensively based on factors such as the material, diameter, wall thickness and construction conditions of the pipeline. The welding quality needs to be strictly controlled during the welding process, including the selection of welding parameters, control of welding speed, cleaning and inspection of welds, etc.; after welding is completed, strict inspection and testing are required to ensure the safety and reliability of the pipeline system.

[0003] In some western regions, during the construction of gas transmission pipelines, gas pipelines are generally laid in loess, and the soil needs to be excavated before pipeline installation and welding. The overall terrain is complex and the soil forms vary. When laying the installation structure for supporting the bottom of the pipeline, in order to ensure that the installation structure can stably support the pipeline and make the welding position accurate, the soil needs to be leveled before placing the installation structure. This method not only reduces the installation efficiency of the pipeline, but also has an impact when the soil settles, requiring the installation base to have dynamic adjustment capabilities. Summary of the invention

[0004] (I) Technical problems to be solved: In view of the deficiencies of the prior art, the present invention provides a gas pipeline installation structure, which has the advantage that the installation base has dynamic leveling capability during the pipeline welding process, thereby solving the problem of deviation at the pipeline welding point caused by soil problems.

[0005] (II) Technical solution: In order to achieve the purpose of the above-mentioned installation base having dynamic leveling capability during the pipeline welding process, the present invention provides the following technical solution: a gas pipeline installation structure, comprising a first installation base and a pipeline fixing assembly for supporting the pipeline, a telescopic rod is arranged above the first installation base, the telescopic rod is connected to the pipeline fixing assembly, the first installation base and the pipeline fixing assembly connected thereto are divided into left and right parts, an electromagnetic module is arranged on the contact surface between the left and right installation bases, the electromagnetic module can generate magnetic force to attract each other, so that the left and right installation bases are connected, and the suction area between the two electromagnetic modules is adjusted. Detect and calculate the horizontal height difference between the left and right mounting bases, and adjust the length of the telescopic rod. A bottom groove is provided under the left and right mounting bases, and end feet are provided on both sides of the bottom groove. The end feet are connected to the first mounting base through a screw rod, and the screw rod is driven to rotate by a motor. A bottom capsule is provided in the bottom groove, and the bottom capsule is filled with liquid. Trigger devices are provided on both sides of the bottom capsule, and the trigger device is connected to the motor at the corresponding position. When the mounting base is tilted, the liquid in the bottom capsule will flow, and there will be more liquid on the side with a lower horizontal height. The trigger device is started, which starts the motor, drives the screw rod to rotate, and raises the height.

[0006] Preferably, the trigger device is a metal electrode. The larger the contact area with the liquid, the greater the current generated. By comparing the currents generated by the electrodes on both sides, the motor is driven to rotate. The liquid filled in the bottom capsule is a conductive solution.

[0007] Preferably, the left and right mounting bases of the first mounting base are connected to the second mounting base through a connecting rod, the second mounting base has the same structure as the first mounting base, and the second mounting base and the first mounting base are arranged along the pipeline direction.

[0008] Preferably, the connecting rod is arranged at the waist-shaped hole of the first mounting base and the second mounting base, and the connecting rod can move in the vertical direction in the waist-shaped hole. When the horizontal heights of the first mounting base and the second mounting base are different, the mounting base located at a higher place will drive the connecting rod upward due to the limitation of the waist-shaped hole, and the mounting base located at a lower place detects the displacement of the connecting rod in the waist-shaped hole and adjusts its own telescopic rod, so that when the horizontal heights of the first mounting base and the second mounting base are different, the horizontal heights of the pipe fixing components connected to themselves can be the same. Through the coordinated work of the first mounting base and the second mounting base and the intelligent adjustment mechanism, the mounting structure can more effectively cope with the challenges brought by complex terrain and ensure that the pipeline can be firmly supported at different heights and inclination angles. Since the mounting structure can automatically detect and adjust the height difference during installation and operation, it can significantly reduce the stress concentration and damage risks of the pipeline caused by factors such as ground subsidence and soil movement.

[0009] Preferably, a sliding groove is provided on one side of the waist-shaped hole facing the inner side of the base, and a connecting rod base capable of moving in the sliding groove is provided at the end point of the connecting rod.

[0010] Preferably, the connecting rod connecting the first mounting base and the second mounting base are two unconnected tubes, and the connecting rod is connected by being covered by a sleeve. The connecting rod is in the sleeve, and the distance between the first mounting base and the second mounting base can be adjusted by adjusting the connection position. At the same time, the setting of the sleeve can also enable the connecting rod to maintain its shape without obvious changes when the length is long.

[0011] Preferably, the pipe fixing assembly is arc-shaped as a whole, and has fixing wheels along the arc array. The fixing wheels are coated with silicone or air bags and are in contact with the pipe. The softness of the silicone or air bags can provide better buffering effect and reduce stress concentration caused by vibration or temperature changes in the pipe. In addition, the arc design also enables the pipe fixing assembly to better support the pipe and reduce the risk of pipe sagging or deformation.

[0012] Preferably, foot nails are provided under the end feet.

[0013] (III) Beneficial effects: Compared with the prior art, the present invention provides a gas pipeline installation structure with the following beneficial effects: 1. The gas pipeline installation structure, by designing the first installation base and the connected pipeline fixing assembly as two independent and identical left and right parts, can flexibly adjust the height of the left and right sides during the installation process. This design ensures that even if the ground is uneven or there is a slight height difference, the pipeline fixing assemblies on both sides can be kept at the same horizontal height by accurately adjusting the length of the telescopic rod, thereby ensuring the accuracy and straightness of the gas pipeline installation and avoiding the stress concentration or damage of the pipeline caused by inconsistent height. The use of a hydraulic rod as the telescopic rod not only provides a strong supporting force, but also through the hydraulic system The precise control realizes the refined operation of height adjustment of the pipeline fixing component. Through the magnetic attraction between the electromagnetic modules and the real-time monitoring of the magnetic flux sensor, the attraction area between the left and right mounting bases can be accurately measured, and then the horizontal height difference between the two can be calculated. The pipeline fixing component is adjusted by the telescopic rod. When encountering uneven ground or soil settlement, the liquid flow in the bottom sac will trigger the motor to drive the screw to rotate, automatically adjust the horizontal state of the mounting base, and achieve dynamic balance, effectively preventing the pipeline from tilting or stress concentration due to ground changes. By accurately adjusting the horizontal height of the pipeline fixing component, the stress concentration or damage of the pipeline caused by height inconsistency is avoided, thereby improving the safety and reliability of the gas pipeline.

[0014] 2. The installation structure of the gas pipeline connects the first installation base and the second installation base through a connecting rod, which not only enhances the structural stability of the entire support system, but also enables the two bases to cooperate with each other during height adjustment. When the height of one base changes due to uneven ground or soil settlement, the other base can quickly sense and make corresponding adjustments to ensure that the pipeline fixing components on the two bases maintain the same height, thereby maintaining the overall straightness of the pipeline. The introduction of intelligent detection technologies such as infrared modules enables the installation base to monitor the position changes of the connecting rod in the waist-shaped hole in real time, and then accurately judge the height difference of the bases on both sides. Based on this information, the system can automatically start the adjustment mechanism of the telescopic rod and extend the telescopic rod of the lower base until the pipeline fixing components on both sides reach the same height. This intelligent adjustment method not only improves the accuracy and efficiency of the adjustment, but also reduces the burden of manual operation. During the actual installation process, long-distance gas pipelines often need to cross a variety of terrains, including flat areas, slopes, potholes, etc. Through the coordinated work of the first mounting base and the second mounting base and the intelligent adjustment mechanism, the mounting structure can more effectively cope with the challenges brought by complex terrain and ensure that the pipeline can be firmly supported at different heights and inclination angles. Since the mounting structure can automatically detect and adjust height differences during installation and operation, it can significantly reduce the risk of pipeline stress concentration and damage caused by factors such as ground subsidence and soil movement. At the same time, a stable support system also helps to reduce pipeline vibration and displacement, improve the overall safety and reliability of the pipeline system, and when the ground subsidence occurs at the location of the first mounting base or the second mounting base, the telescopic rod can be adjusted with reference to the mounting base at a higher horizontal position, that is, where no subsidence occurs, to achieve dynamic balance of the pipeline mounting base during welding.

[0015] 3. The installation structure of the gas pipeline divides the installation base into two independent left and right parts and connects them through an electromagnetic module, making the installation and disassembly process simpler and faster. During installation, the left and right installation bases can be placed from both sides under the pipeline respectively and quickly connected using the electromagnetic module without complicated bolt fixing or welding processes. Similarly, when disassembly is required, the installation base can be easily separated by simply disconnecting the electromagnetic connection, avoiding the problem of difficult disassembly due to pipeline welding. The electromagnetic module can adjust the area of ​​magnetic force generated. This design enables the left and right installation bases to be firmly connected even when there is a horizontal height difference. By adjusting the magnetic area, it can be ensured that the installation bases at different heights can fit tightly and maintain sufficient connection strength. This flexibility enables the installation structure to better adapt to complex terrain and installation conditions.

[0016] 4. The installation structure of the gas pipeline makes the connecting rod more stable and smooth during movement by arranging a slide groove and a connecting rod base in the waist-shaped hole. The connecting rod base increases the contact area and weight of the connecting rod end, which helps to reduce the shaking and deviation of the connecting rod during movement, thereby improving the stability and safety of the entire structure. In addition, the stable connecting rod connection also helps to maintain the horizontal height consistency of the pipeline fixing component and ensure the overall performance of the pipeline system. The pipeline fixing component adopts an arc design and fixes the wheel along the arc array. At the same time, the fixing wheel is coated with silicone or air bags. This design can better adapt to the shape of the pipeline and reduce friction and wear between the pipeline and the softness of the silicone or air bags can provide better buffering effect and reduce the stress concentration caused by vibration or temperature changes in the pipeline. In addition, the arc design also enables the pipeline fixing component to better support the pipeline and reduce the risk of pipeline sagging or deformation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 2 and Figure 6 The installation structure of the gas pipeline includes a first installation base 1 and a pipeline fixing component 2 for supporting the pipeline. A telescopic rod 21 is arranged above the first installation base 1, and the telescopic rod 21 is connected to the pipeline fixing component 2. The first installation base 1 and the pipeline fixing component 2 connected thereto are divided into left and right parts. An electromagnetic module 123 is arranged on the contact surface between the left and right installation bases. The electromagnetic module 123 can generate magnetic force to attract each other, so that the left and right installation bases are connected. The left and right installation bases are placed at the positions where the pipeline needs to be installed, and the electromagnetic module 123 is started to attract them to form the first installation base 1, and the attraction area between the two electromagnetic modules is detected. A magnetic flux sensor is arranged next to the electromagnetic module 123. The magnetic flux is a physical quantity that describes the distribution of the magnetic field. The number of magnetic lines of induction passing through a certain area is called the magnetic flux. The size of the magnetic flux is related to the strength of the magnetic field and the magnetic The distribution range of the magnetic field is related to that of the magnetic field. During the attraction process of the two electromagnets, due to the superposition effect of the magnetic field strength, the number of magnetic flux lines passing through a certain area, that is, the magnetic flux, will also increase accordingly. The readings of the magnetic flux sensor are recorded before, during and after the electromagnetic module 123 is attracted. Note that the current, number of turns and other parameters that may affect the magnetic flux are recorded. According to the calculation formula of the magnetic flux Φ=BScosθ, the relationship between the change of the magnetic flux and the attraction area is analyzed. Assuming that the magnetic field strength B and the angle θ remain unchanged or the change is negligible during the attraction process, the change of the magnetic flux mainly reflects the change of the attraction area S. By comparing the magnetic flux values ​​under different attraction states, the situation of the attraction area can be indirectly inferred. The horizontal height difference between the left and right mounting bases is calculated through the attraction area, and the length of the telescopic rod 21 is adjusted according to the height difference so that the left and right pipe fixing components 2 are at the same level.

[0030] See also Figure 4-Figure 7The bottom of the left and right mounting bases is provided with a bottom groove 12, and the bottom groove 12 is provided with end feet 101 on both sides. The end feet 101 are connected to the first mounting base 1 through a screw rod, and the screw rod is driven to rotate by a motor. Figure 4 When the end foot 101 is fixed on the ground, one side of the mounting base is lifted by rotating the screw rod, and a bottom capsule 121 is provided in the bottom groove 12, and the bottom capsule 121 is filled with liquid. Trigger devices are provided on both sides of the bottom capsule 121, and the trigger devices are connected to the motors at the corresponding positions. When the mounting base is tilted, the liquid in the bottom capsule 121 will flow, and there will be more liquid on the side with a lower horizontal height. The trigger device is started, the motor is started, and the screw rod is driven to rotate to lift the height, so that the mounting base as a whole can always maintain a horizontal state. When the bottom horizontal heights of the mounting bases on the left and right sides are different, the pipe fixing components on the left and right sides are adjusted by adjusting the telescopic rod 21. 2 The horizontal height remains the same, so that the height of the left and right sides can be flexibly adjusted during the installation process. At the same time, the fixation at a high horizontal position can be used as a reference. When soil settlement occurs, dynamic balance can be effectively performed, and the pipeline tilts during welding. This design ensures that even if the ground is uneven or there is a slight height difference, the length of the telescopic rod can be accurately adjusted to keep the pipeline fixing components on both sides at the same horizontal height, thereby ensuring the accuracy and straightness of the gas pipeline installation and avoiding stress concentration or damage to the pipeline caused by inconsistent height. The telescopic rod 21 is specifically a hydraulic rod, which is adjusted by hydraulic pressure to ensure the adjustment accuracy and support for the pipeline.

[0031] The trigger device is a metal electrode. The larger the contact area with the liquid, the larger the conduction area and the generated current. By comparing the currents generated by the electrodes on both sides, the motor is driven to rotate. The liquid filled in the bottom capsule 121 is a conductive solution. When the mounting base is placed horizontally, the contact area between the solution in the bottom capsule 121 and the trigger device is small, and the contact areas on both sides are the same. When the mounting base is tilted, the liquid in the bottom capsule 21 will move to a lower horizontal position, thereby increasing the contact area between the trigger device on the lower side and the solution, increasing the conducted current, and the motor drives the screw rod to rotate, thereby lifting the lower horizontal side of the mounting base and restoring the overall level.

[0032] See also Figure 1-Figure 5The left and right mounting bases of the first mounting base 1 are connected to the second mounting base 3 through a connecting rod 11. The structure of the second mounting base 3 is the same as that of the first mounting base 1. The second mounting base 3 and the first mounting base 1 are arranged along the pipeline direction. The connecting rod 11 is arranged at the waist-shaped hole 112 of the first mounting base 1 and the second mounting base 3, and the connecting rod 11 can move in the vertical direction in the waist-shaped hole 112. When the first mounting base 1 and the second mounting base 3 are at different horizontal heights, the mounting base located at a higher position will bring the connecting rod 11 upward due to the limitation of the waist-shaped hole 112. The installation base at the lower position detects the displacement of the connecting rod 11 in the waist-shaped hole 112, for example, the position of the connecting rod is detected by an infrared module, and the telescopic rod 21 thereof is adjusted, so that when the horizontal heights of the first installation base 1 and the second installation base 3 are different, the horizontal heights of the pipe fixing assembly 2 connected to themselves can be the same. When the height of one side of the base changes due to uneven ground or soil settlement, the base on the other side can quickly sense it and make corresponding adjustments to ensure that the pipe fixing assemblies on the two bases maintain the same height, thereby maintaining the overall straightness of the pipeline.

[0033] See also Figure 3-Figure 6 , the first mounting base 1 and the left and right mounting bases of the second mounting base 3 are connected by setting an electromagnetic module 123 on the contact surface. The electromagnetic module 123 can adjust the area of ​​the magnetic force. When there is a horizontal height difference between the left and right mounting bases, the area of ​​the magnetic force generated by the electromagnetic module 123 after powering on can be adjusted to connect the mounting bases. This method of dividing the mounting base into two left and right parts and enabling connection can put the mounting base in from both sides under the pipe for installation and removal, which is simpler and more convenient. There is no need to worry about the removal of the mounting base after the pipe welding is completed. The electromagnetic module can adjust the area of ​​the magnetic force. This design enables the left and right mounting bases to still achieve a stable connection when there is a horizontal height difference. By adjusting the magnetic area, it can be ensured that the mounting bases at different heights can fit tightly and maintain sufficient connection strength. This flexibility enables the mounting structure to better adapt to complex terrain and installation conditions.

[0034] See also Figure 9-10 The waist-shaped hole 112 is provided with a slide groove 113 on one side facing the inner side of the base, and the connecting rod 11 is provided with a connecting rod base 1101 which can move in the slide groove 113 at the end point. The slide groove 113 and the connecting rod base 1101 make the movement of the connecting rod 11 easier. At the same time, the connecting rod base 1101 increases the contact area and weight of the end of the connecting rod 11, making it more stable during operation.

[0035] See also Figure 1 and Figure 8The connecting rod 11 connecting the first mounting base 1 and the second mounting base 3 are two unconnected tubes. The connecting rod 11 is covered by a sleeve 111 to achieve connection. The connecting rod 11 is in the sleeve 111. By adjusting the connection position, the distance between the first mounting base 1 and the second mounting base 3 can be adjusted. At the same time, the setting of the sleeve 111 can also enable the connecting rod 11 to maintain its shape without obvious changes when the length is long.

[0036] The pipe fixing assembly 2 is arc-shaped as a whole, and has fixing wheels 22 along the arc array. The fixing wheels 22 are coated with silicone or air bags and are in contact with the pipe. The softness of the silicone or air bags can provide a better buffering effect and reduce the stress concentration caused by vibration or temperature changes in the pipe. In addition, the arc design also enables the pipe fixing assembly to better support the pipe and reduce the risk of pipe sagging or deformation.

[0037] Foot nails are arranged under the end foot 101, and the foot nails can effectively penetrate into the soil to play a fixing role.

[0038] Working principle: During the gas pipe installation and welding process, the topography and soil settlement will have a direct impact on the welding operation. When welding operations are carried out in the western region, the gas pipe needs to be placed in the excavated pit, and the soil is generally soft and uneven. When placing the pipeline installation base, the pit needs to be leveled and compacted to place the installation base stably in the pit, and then the pipeline is placed on the installation frame for welding. The overall efficiency is low. The invention is provided with a telescopic rod 21 above the first installation base 1, and the telescopic rod 21 is connected to the pipeline fixing component 2. The first installation base 1 and the corresponding The connected pipe fixing component 2 is divided into two parts, the left and right parts, and an electromagnetic module 123 is arranged on the contact surface between the left and right mounting bases. The electromagnetic module 123 can generate magnetic force to attract each other, so that the left and right mounting bases are connected. The left and right mounting bases are placed at the positions where the pipes need to be installed, and the electromagnetic module 123 is started to attract them to form the first mounting base 1, and the attraction area between the two electromagnetic modules is detected. By arranging a magnetic flux sensor next to the electromagnetic module 123, the magnetic flux is a physical quantity that describes the distribution of the magnetic field. The number of magnetic lines of induction passing through a certain area is called the magnetic flux. The magnitude of the magnetic flux is related to the strength of the magnetic field and the distribution range of the magnetic field. During the process of the two electromagnets being attracted, due to the superposition effect of the magnetic field strength, the number of magnetic flux lines passing through a certain area, i.e., the magnetic flux, will also increase accordingly. The readings of the magnetic flux sensor are recorded before, during, and after the electromagnetic module 123 is attracted. Note that the parameters that may affect the magnetic flux, such as the current and number of turns of the electromagnet, are recorded. According to the calculation formula of the magnetic flux Φ=BScosθ, the relationship between the change in magnetic flux and the attraction area is analyzed. It is assumed that the magnetic field strength B and the angle θ remain unchanged or change during the attraction process. If the magnetic flux is ignored, the change of the magnetic flux mainly reflects the change of the attraction area S. By comparing the magnetic flux values ​​under different attraction states, the attraction area can be indirectly inferred. The horizontal height difference between the left and right mounting bases is calculated by the attraction area. The length of the telescopic rod 21 is adjusted according to the height difference so that the left and right pipe fixing components 2 are at the same horizontal height. A bottom groove 12 is provided under the left and right mounting bases. End feet 101 are provided on both sides of the bottom groove 12. The end feet 101 are connected to the first mounting base 1 through a screw rod, and the screw rod is driven to rotate by a motor. See Figure 4When the end foot 101 is fixed on the ground, one side of the mounting base is lifted by rotating the screw rod, and a bottom capsule 121 is provided in the bottom groove 12, and the bottom capsule 121 is filled with liquid. Trigger devices are provided on both sides of the bottom capsule 121, and the trigger devices are connected to the motors at the corresponding positions. When the mounting base is tilted, the liquid in the bottom capsule 121 will flow, and there will be more liquid on the side with a lower horizontal height. The trigger device is started, and the motor is started to drive the screw rod to rotate and lift the height, so that the mounting base as a whole can always remain in a horizontal state. When the horizontal heights of the bottom of the mounting bases on the left and right sides are different, the horizontal heights of the pipe fixing components 2 on the left and right sides are kept the same by adjusting the telescopic rod 21, so that the heights of the left and right sides can be flexibly adjusted during the installation process. At the same time, the fixation at a high horizontal position can be used as a reference. When soil settlement occurs, dynamic balance can be effectively performed, and the surface pipeline is tilted during welding. This design ensures that even if When the ground is uneven or there is a slight height difference, the length of the telescopic rod can be accurately adjusted to keep the pipe fixing components on both sides at the same horizontal height, thereby ensuring the accuracy and straightness of the gas pipeline installation and avoiding stress concentration or damage to the pipeline caused by height inconsistency. The telescopic rod 21 is specifically a hydraulic rod, which is adjusted by hydraulic pressure to ensure the adjustment accuracy and the supporting force for the pipeline. At the same time, the mounting base connects the first mounting base 1 and the second mounting base 3 respectively through the connecting rod 11. When the first mounting base 1 and the second mounting base 3 are not on the same horizontal line, the mounting base in a higher position will drive the connecting rod 11 to move upward, and the other mounting base in a lower position will detect the displacement of the connecting rod 11. The length of the telescopic rod 21 is adjusted according to the displacement, so that the pipe fixing components 2 of the first mounting base 1 and the second mounting base 3 can maintain the same horizontal height, avoiding the pipeline from tilting, causing deviations in the welding position, and unable to weld accurately.
