Description

Technical Field

[0001] This utility model belongs to the field of natural gas long-distance pipeline maintenance technology, specifically a multi-functional maintenance platform for natural gas long-distance pipelines. Background Technology

[0002] Natural gas is an important energy resource, mainly used as fuel and chemical raw material. Since most natural gas fields are concentrated in deserts, polar permafrost zones, mountains, and oceans, the distance from the production site to the usage site is often very far. Therefore, pipeline transportation has become the most reasonable way to transport natural gas.

[0003] Steel pipes are the most commonly used material for long-distance natural gas pipelines due to their advantages such as high strength, good sealing and anti-aging properties, and ability to withstand large pressure and temperature changes. However, due to natural disasters, corrosion, third-party damage, pipeline aging and wear, long-distance natural gas pipelines require regular maintenance. Some long-distance natural gas pipelines need to be installed overhead due to the usage scenarios. The overhead installation height varies when crossing rivers, pedestrian walkways, highways and railways. The existing maintenance platforms for long-distance natural gas pipelines are mostly at a fixed height and cannot adapt to pipelines with different overhead heights.

[0004] To address these issues, those skilled in the art have proposed a multifunctional maintenance platform for long-distance natural gas pipelines. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a multifunctional maintenance platform for long-distance natural gas pipelines, which solves the problem that existing maintenance platforms for long-distance natural gas pipelines are mostly at a fixed height and cannot adapt to pipelines at different overhead heights.

[0006] A multifunctional maintenance platform for a long-distance natural gas pipeline includes a base plate, a first fixed plate fixedly connected to the upper surface of the base plate, a slide rail fixedly installed on the upper surface of the base plate, a slider slidably connected to two slide rails, a first sliding plate fixedly connected to the slider, a first support plate rotatably connected to the first fixed plate, a second support plate rotatably connected to the first sliding plate, a second fixed plate rotatably connected to the first support plate, a top plate connected to the second fixed plate and the second sliding plate.

[0007] Preferably, the first support plate and the second support plate are rotatably connected, and two sets of the first support plate and the second support plate are provided.

[0008] Preferably, the lower surface of the base plate is equipped with self-locking rollers, the upper surface of the top plate is equipped with a guardrail, and the guardrail is connected to a closed door.

[0009] Preferably, a mounting bracket is fixedly installed on the upper surface of the base plate, a drive motor is fixedly installed on the mounting bracket, a threaded rod is fixedly connected to the output end of the drive motor, the threaded rod is threadedly connected to the first sliding plate, and the threaded rod is rotatably connected to the first fixed plate.

[0010] Preferably, the second fixing plate is fixedly connected to the lower surface of the top plate, a side plate is fixedly installed on the lower surface of the top plate, a guide rod is fixedly connected to the opposite surface of the side plate and the second fixing plate, and the second sliding plate is slidably connected to the guide rod.

[0011] Preferably, the upper end of the guardrail is connected to a shelf, the shelf has a storage slot, the shelf is provided with a limit frame, and the shelf is fixedly installed with hooks.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In this utility model, the first sliding plate carries the slider along the slide rail. At this time, the intersection angle of the first support plate and the second support plate changes, thereby changing the height of the top plate. The height of the top plate can be adjusted according to actual needs, which facilitates the maintenance of overhead long-distance pipelines by staff.

[0014] 2. This utility model uses a drive motor to rotate a threaded rod, which in turn drives the first sliding plate to slide using its threads. This mechanical method improves the lifting efficiency of the top plate.

[0015] 3. This utility model changes the height of the top plate by adjusting the intersection angle of the first support plate and the second support plate, and the platform can be moved and stopped by the self-locking rollers. Various maintenance tools can be placed on the shelf, which has multiple functions and improves its practicality. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] Example 1

[0024] As attached Figure 1 To be continued Figure 4 As shown, this embodiment provides a multifunctional maintenance platform for a long-distance natural gas pipeline, including a base plate 1. A first fixed plate 2 is fixedly connected to the upper surface of the base plate 1. A slide rail 3 is fixedly installed on the upper surface of the base plate 1. A slider 4 is slidably connected to the two slide rails 3. The slide rails 3 and the slider 4 cooperate to assist the first sliding plate 5 in sliding smoothly. The slider 4 is fixedly connected to the first sliding plate 5. A first support plate 6 is rotatably connected to the first fixed plate 2. A second support plate 7 is rotatably connected to the first sliding plate 5. When the distance between the first sliding plate 5 and the first fixed plate 2 changes, the intersection angle of the first support plate 6 and the second support plate 7 will change, thereby changing the height of the top plate 10. A second sliding plate 8 is rotatably connected to the first support plate 6. A second fixed plate 9 is rotatably connected to the second support plate 7. The second fixed plate 9 and the second sliding plate 8 are connected to the top plate 10. Workers stand on the upper surface of the top plate 10 to perform maintenance work.

[0025] As can be seen from the above, when the staff stands on the upper surface of the top plate 10, the first sliding plate 5 slides on the slide rail 3 with the slider 4, which changes the distance between the first sliding plate 5 and the first fixed plate 2. At this time, the intersection angle of the first support plate 6 and the second support plate 7 will change, thereby adjusting the height of the top plate 10 to match the overhead long-distance pipeline, making it easier for the staff to inspect and maintain the overhead long-distance pipeline.

[0026] Example 2

[0027] As attached Figure 1 To be continued Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that the first support plate 6 and the second support plate 7 are rotatably connected, and there are two sets of the first support plate 6 and the second support plate 7, which can improve the support strength of the top plate 10.

[0028] Specifically, the lower surface of the base plate 1 is equipped with self-locking rollers 11, which enable the platform to move and stop stably. The upper surface of the top plate 10 is equipped with a guardrail 12, which provides safety for the staff. The guardrail 12 is connected to a closed door 13. One end of the guardrail 12 is hinged to the closed door 13, and the other end is connected to the closed door 13 by a lock. When working, the closed door 13 is closed to ensure safety during the maintenance process.

[0029] Furthermore, a mounting bracket 14 is fixedly installed on the upper surface of the base plate 1, and a drive motor 15 is fixedly installed on the mounting bracket 14. The drive motor 15 is a power source, and a threaded rod 16 is fixedly connected to the output end of the drive motor 15. The threaded rod 16 is threadedly connected to the first sliding plate 5 and rotatably connected to the first fixed plate 2. When the drive motor 15 works, it drives the threaded rod 16 to rotate. The first sliding plate 5 is affected by the thread and moves the slider 4 along the slide rail 3. A control box is installed on the upper surface of the top plate 10. The operator controls the start, stop and speed of the drive motor 15 through the control box.

[0030] Furthermore, the second fixed plate 9 is fixedly connected to the lower surface of the top plate 10, and a side plate 17 is fixedly installed on the lower surface of the top plate 10. A guide rod 18 is fixedly connected to the opposite surface of the side plate 17 and the second fixed plate 9. The second sliding plate 8 is slidably connected to the guide rod 18. When the intersection angle of the first support plate 6 and the second support plate 7 changes, the second sliding plate 8 slides along the guide rod 18, thereby changing the distance between the second fixed plate 9 and the second sliding plate 8. The second sliding plate 8 slides with the top plate 10 through the side plate 17 and the guide rod 18.

[0031] Furthermore, a shelf 19 is connected to the upper end of the guardrail 12. The shelf 19 is used to place maintenance tools. The shelf 19 has a storage slot 20, a limit frame 21, and a hook 22. By setting the storage slot 20, the limit frame 21, and the hook 22, the maintenance tools can be limited to prevent them from falling from a height and improve safety.

[0032] As can be seen from the above, the platform is moved to the designated area by the self-locking roller 11. The staff stands on the upper surface of the top plate 10. The drive motor 15 drives the threaded rod 16 to rotate. The first sliding plate 5 is affected by the thread and moves the slider 4 along the slide rail 3, changing the distance between the first sliding plate 5 and the first fixed plate 2. At this time, the intersection angle of the first support plate 6 and the second support plate 7 changes, causing the second sliding plate 8 to move along the guide rod 18. The distance between the second sliding plate 8 and the second fixed plate 9 also changes. Due to the change in the intersection angle of the first support plate 6 and the second support plate 7, the height of the top plate 10 is adjusted to match the overhead long-distance pipeline, which facilitates the staff to inspect the overhead long-distance pipeline. The inspection tools are limited by the storage trough 20, the limiting frame 21, and the hook 22 to prevent the inspection tools from falling from a height and improve safety.
