Description

Technical Field

[0001] This invention relates to the field of pipeline welding technology, and more specifically, to a long-distance pipeline welding platform. Background Technology

[0002] A long-distance pipeline welding platform is an auxiliary welding device used in long-distance pipeline transportation. Long-distance pipelines are typically installed in the field for the storage or transportation of oil, natural gas, urban water supply, and urban drainage. In traditional welding operations, operators use ladders for open-air work. Because long-distance pipelines have long transport distances and are usually composed of pipes of varying diameters, it is inconvenient for operators to move between the pipeline sides for welding operations, resulting in low pipeline welding efficiency.

[0003] In conclusion, how to improve the efficiency of pipeline welding is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a long-distance pipeline welding platform that can improve pipeline welding efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A welding platform for long-distance pipelines includes a platform support, an external ladder, and a human-shaped ladder.

[0007] The platform support is provided with a working channel for placing pipes and performing welding operations;

[0008] The external ladder is used to facilitate the movement of workers on both sides of the pipe and on the platform support. The external ladder is located on one side of the platform support and connects both sides of the working passage.

[0009] The human-shaped ladder includes a first ladder and a second ladder respectively placed on both sides of the pipe. The top ends of the first ladder and the second ladder are hinged to one end of a pair of turnbuckles. The other end of the pair of turnbuckles is connected to a slide rail fastener, and the slide rail fastener is slidably mounted on the slide rail. Both ends of the platform support are provided with channel steel rails arranged along the axial direction perpendicular to the working channel. The slide rail is slidably mounted between the slots of the two channel steel rails.

[0010] Preferably, the platform support includes a support plate for placing welding equipment and several pillars. The support plate is fixed on the several pillars and is located above the working channel. The several pillars are evenly distributed on both sides of the working channel.

[0011] Preferably, each of the aforementioned supports is provided with a lifting ring at its top for hoisting operations.

[0012] Preferably, the top of several of the support columns is fixed with a first fireproof and flame-retardant cloth for shielding the welding equipment, and the edges of the support plate are all provided with a second fireproof and flame-retardant cloth for shielding the working passage.

[0013] Preferably, the second fireproof and flame-retardant fabric has a plurality of through holes, and a light-transmitting flexible plate for light transmission in the working passage is fixed in the through holes.

[0014] Preferably, the lower surface of the support plate is provided with a light strip to increase the brightness of the working channel.

[0015] Preferably, the welding equipment includes a welding machine for welding the pipe, an electrical box for supplying power to the welding operation, and a toolbox for storing everyday tools, and the welding machine, the electrical box, and the toolbox are respectively placed at different positions on the upper surface of the support plate.

[0016] Preferably, the welding equipment further includes a self-priming purifier for treating harmful gases generated during welding operations. The self-priming purifier includes a fume sensor and a suction device. The fume sensor is fixed to the lower surface of the support plate, and the suction device is connected to the working channel.

[0017] Preferably, the external ladder is an arc-shaped ladder, the top of which is connected to the support plate. The arc-shaped ladder includes two arc-shaped rods and a plurality of connecting rods disposed between the two arc-shaped rods, and the arc-shaped rods are welded to the adjacent support column.

[0018] Preferably, both the support column and the arc-shaped rod are provided with adjustable feet at their bottom ends for adjusting height.

[0019] Compared to the aforementioned background technology, the present invention provides a long-distance pipeline welding platform, including a platform support, an external ladder, and a human-shaped ladder; the platform support is provided with a working channel for placing the pipeline and performing welding operations; the external ladder is used to facilitate the movement of operators on both sides of the pipeline and on the platform support, and the external ladder is located on one side of the platform support and connects both sides of the working channel; the human-shaped ladder includes a first ladder and a second ladder for being placed on both sides of the pipeline respectively, the top sides of the first ladder and the second ladder are both hinged to one end of a pair of turnbuckles, the other end of the pair of turnbuckles is connected to a slide rail fastener, and the slide rail fastener is slidably mounted on the slide rail; both ends of the platform support are provided with channel steel rails arranged axially along the vertical working channel, and the slide rail is slidably mounted between the slots of the two channel steel rails.

[0020] During the operation of the aforementioned long-distance pipeline welding platform, the welding platform is positioned above the pipeline weld. Workers enter the work channel and control the slide rails to slide left and right along the slots of two channel steel rails, allowing the human-shaped ladders located on the slide rails to move left and right. This ensures that the first and second ladders of the human-shaped ladders are positioned on opposite sides of the pipeline. The human-shaped ladders are then controlled to move back and forth along the slide rails to complete the welding work on one side of the pipeline. During welding, because the tops of both the first and second ladders are hinged to one end of a pair of turnbuckles, and the other end of the turnbuckles is connected to the slide rail fasteners, the first and second ladders can rotate relative to each other, allowing adjustment of the angle between them. Simultaneously, the height of the human-shaped ladders can be adjusted using the telescopic function of the turnbuckles, making them suitable for welding pipelines of different diameters. After completing welding on one side of the pipeline, workers use the external ladders to enter the other side of the work channel to complete the welding work on the other side of the pipeline. This solves the problem of workers being unable to move between the two sides of the long pipeline due to its length.

[0021] Therefore, the long-distance pipeline welding platform provided in this application utilizes the up-down, left-right, and forward-backward movement functions of the adjustable-angle humanoid ladder to make the welding platform suitable for welding operations on pipelines of different diameters. The external ladder facilitates the movement of operators on both sides of the pipeline, thereby improving the convenience of welding operations and thus increasing pipeline welding efficiency.

Detailed Implementation

[0031] 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.

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] The core of this invention is to provide a welding platform for long-distance pipelines, which can improve pipeline welding efficiency.

[0034] Please refer to Figures 1-6This application provides a long-distance pipeline welding platform, including a platform support 2, an external ladder 6, and a human-shaped ladder 7. The platform support 2 is provided with a working channel 3 for placing the pipeline and performing welding operations. The external ladder 6 is used to facilitate the movement of operators on both sides of the pipeline and on the platform support 2. The external ladder 6 is located on one side of the platform support 2 and connects both sides of the working channel 3. The human-shaped ladder 7 includes a first ladder and a second ladder for being placed on both sides of the pipeline. The tops of the first ladder and the second ladder are both hinged to one end of a pair of turnbuckles 10. The other end of the pair of turnbuckles 10 is connected to a slide rail fastener 11, and the slide rail fastener 11 is slidably mounted on a slide rail 9. Both ends of the platform support 2 are provided with channel steel rails 8 arranged axially along the vertical working channel 3. The slide rail 9 is slidably mounted between the slots of the two channel steel rails 8.

[0035] Specifically, the long-distance pipeline welding platform includes a platform support 2, an external ladder 6, and a human-shaped ladder 7. The platform support 2 is located above the working channel 3, which is used to place the pipeline so that workers can move within the channel to perform pipeline welding operations. The external ladder 6 is located outside the working channel 3 and on one side of the platform support 2, connecting the two sides of the working channel 3. The human-shaped ladder 7 is located inside the working channel 3 and includes a first ladder and a second ladder, which are respectively placed on both sides of the pipeline. The front and rear ends of the platform support 2 are... A channel steel rail 8 is provided along the vertical working channel 3. A slide rail 9 is provided between the slots of the front channel steel rail 8 and the rear channel steel rail 8. The two ends of the slide rail 9 can slide left and right along the slot. The top two sides of the first ladder are hinged to one end of a pair of turnbuckles 10. The top two sides of the second ladder are hinged to one end of a pair of turnbuckles 10. That is, the top of the first ladder and the top of the second ladder can be rotatably connected through a pair of turnbuckles 10. The other end of the pair of turnbuckles 10 is fixed to the slide rail fastener 11. The slide rail fastener 11 can be slidably mounted on the slide rail 9 and slide back and forth along the slide rail 9.

[0036] During the operation of the aforementioned long-distance pipeline welding platform, the welding platform is positioned above the pipeline weld. Workers enter the work passage and control the slide rail 9 to slide left and right along the slots of the two channel steel rails 8, causing the human-shaped ladder 7 located on the slide rail 9 to move left and right. This ensures that the first and second ladders of the human-shaped ladder 7 are positioned on opposite sides of the pipeline. The human-shaped ladder 7 is then controlled to move back and forth along the slide rail 9 to ensure the welding work on one side of the pipeline is completed. During the welding process, the tops of both the first and second ladders of the human-shaped ladder 7 are hinged to one end of a pair of turnbuckles 10, and the pair of turnbuckles... The other end of the bolt 10 is connected to the slide rail fastener 11, so the first ladder and the second ladder can rotate relative to each other, and the angle between the first ladder and the second ladder can be adjusted. At the same time, the height of the human-shaped ladder 7 can be adjusted by using the telescopic function of a pair of turnbuckles 10, so that the human-shaped ladder 7 can be used for welding operations on pipes of different diameters. After the operator completes the welding on one side of the pipe, he can use the external ladder 6 to enter the other side of the working channel 3 to complete the welding operation on the other side of the pipe. This solves the problem that it is inconvenient for operators to move between the two sides of the long-distance pipeline.

[0037] Therefore, the long-distance pipeline welding platform provided in this application utilizes the up-down, left-right, and forward-backward movement functions of the adjustable-angle humanoid ladder 7 to make the welding platform suitable for welding operations on pipelines of different diameters. The external ladder 6 facilitates the movement of operators on both sides of the pipeline, thereby improving the convenience of welding operations for operators and thus improving pipeline welding efficiency.

[0038] Optionally, the slide rail fastener 11 of this application can be a flexible hose, which is slidably sleeved on the slide rail 9. Other types of slide rail fasteners 11 can also be used, as long as the slide rail fastener 11 can slide back and forth along the slide rail 9.

[0039] Based on the above embodiments, the platform support 2 includes a support plate 20 for placing welding equipment and several pillars 21. The support plate 20 is fixed on the several pillars 21. The support plate 20 is located above the working channel 3, and the several pillars 21 are evenly arranged on both sides of the working channel 3.

[0040] Specifically, the platform support 2 includes a support plate 20 and four pillars 21. The support plate 20 is located above the working channel 3, and the four pillars 21 are fixedly installed at the four corners of the support plate 20. Equipment for welding operations is placed on the support plate 20 to facilitate the transportation and storage of the welding equipment.

[0041] Optionally, the number of support pillars 21 in this application is not unique and can be set according to actual needs, with the goal of fixing the support plate 20.

[0042] Based on the above embodiments, each of the tops of several support columns 21 is provided with a lifting ring 1 for hoisting operations, so that the crane can hook the lifting lug 1 at the top of the support column 21 to move the welding platform above the pipeline weld, which facilitates the overall movement of the pipeline welding platform and improves the welding efficiency of long-distance pipelines.

[0043] Based on the above embodiments, a first fireproof and flame-retardant cloth 4 for shielding welding equipment is fixed at the top of several pillars 21, and a second fireproof and flame-retardant cloth 5 for shielding the operation passage 3 is provided around the edges of the support plate 20.

[0044] Specifically, a first fireproof and flame-retardant cloth 4 is fixedly installed at the top of several support pillars 21 to cover the welding equipment on the support plate 20. A second fireproof and flame-retardant cloth 5 is fixedly installed around the edges of the support plate 20 to cover the work passage 3. Thus, the welding equipment can be protected from rain by the first fireproof and flame-retardant cloth 4, avoiding damage to the welding equipment and affecting the welding efficiency. In addition, during pipeline welding operations, the second fireproof and flame-retardant cloth 5 can be used to protect against wind and rain, avoiding the impact of weather on the quality and efficiency of pipeline welding during field construction.

[0045] It should be noted that, since fire safety measures are required during welding operations, fire-retardant fabric with windproof and rainproof properties is selected. The windproof and fire-retardant fabric in this application is Class A fire-retardant fabric.

[0046] Based on the above embodiments, the second fireproof and flame-retardant cloth 5 is provided with several through holes, and a light-transmitting soft plate 18 for light transmission in the working channel 3 is fixed in the through holes, so that when the pipe welding operation is carried out, the second fireproof and flame-retardant cloth 5 is lowered to block the working channel 3, and the working channel 3 can still retain natural light. In addition, it is convenient for the operators to observe the conditions in the working channel 3 through the light-transmitting soft plate 18 to ensure the safety in the working channel 3.

[0047] Optionally, the number of light-transmitting flexible plates 18 in this application is not unique and can be set according to actual needs.

[0048] Based on the above embodiments, the lower surface of the support plate 20 is provided with a light strip 19 for increasing the brightness of the working channel 3, which serves as a supplementary light source for the natural light transmitted through the light-transmitting flexible plate 18, ensuring sufficient light source in the working channel 3, thereby facilitating pipe welding operations for workers and avoiding affecting the quality and efficiency of pipe welding.

[0049] Optionally, the light strip 19 in this application is a low-voltage light strip 19 with stable performance, long life and high safety, or other types of light strip 19 can be selected according to actual needs.

[0050] Based on the above embodiments, the welding equipment includes a welding machine 12 for pipe welding, an electrical box 13 for powering the welding operation, and a toolbox 14 for storing daily tools. The welding machine 12, the electrical box 13, and the toolbox 14 are placed at different positions on the upper surface of the support plate 20 so that the operators can use and store the welding tools when performing pipe welding operations.

[0051] Based on the above embodiments, the welding equipment also includes a self-priming purifier 15 for treating harmful gases generated during welding operations. The self-priming purifier 15 includes a fume sensor 16 and an air intake device. The fume sensor 16 is fixed to the lower surface of the support plate 20, and the air intake device is connected to the working channel 3.

[0052] Specifically, since harmful gases are generated during pipe welding operations, a self-priming purifier 15 is installed on the upper surface of the support plate 20. The self-priming purifier 15 includes a smoke sensor 16 and an air intake device. The smoke sensor 16 is fixedly installed on the lower surface of the support plate 1, located in the working channel 3. The air intake device is connected to the working channel 3. When the operator is welding, the smoke sensor 16 detects harmful gases and transmits the signal to the controller of the self-priming purifier 15. The controller controls the air intake device in the self-priming purifier 15 to intake the gases, thereby protecting the health of the operators and protecting the environment.

[0053] Based on the above embodiments, the external ladder 6 is an arc-shaped ladder, the top of which is connected to the support plate 20. The arc-shaped ladder includes two arc-shaped rods and several connecting rods disposed between the two arc-shaped rods, and the arc-shaped rods are welded to the adjacent support column 21.

[0054] Specifically, the external ladder 6 is used to facilitate the movement of workers on both sides of the pipeline and on the support plate 20. The external ladder 6 is a curved ladder with high safety and easy climbing. The top of the curved ladder is welded to the support plate 1 so that workers can climb onto the support plate 20. The curved ladder includes two curved rods and several connecting rods. The connecting rods are evenly welded between the two curved rods. The curved rods are welded to the adjacent support column 21, so that the curved ladder is welded to the platform support as a whole, which makes it easy for the crane to lift and move the whole welding platform stably.

[0055] Based on the above embodiment, both the support column 21 and the arc-shaped rod are equipped with adjustable feet 17 at their bottom ends for height adjustment. Since long-distance pipelines are usually installed in the field, the pipeline welding platform is often placed on uneven ground. The adjustable feet 17 are fixedly connected to the bottom ends of the support column 21 and the arc-shaped rod to facilitate the adjustment of the height of the support column 21 and the arc-shaped rod, thereby ensuring that the pipeline welding platform is stably placed on the ground.
