Description

Technical Field

[0001] This utility model relates to the field of pipeline installation equipment technology, and in particular to an adjustable base device for large pipeline installation. Background Technology

[0002] In the installation of large-diameter pipelines, the newly installed pipeline is aligned and welded to the existing pipeline. Traditional pipeline installation bases often fail to meet the precise adjustment requirements for pipeline position and height during installation. For example, in large-scale water conservancy projects and petrochemical pipeline laying projects, large-diameter pipelines are heavy and long, requiring frequent adjustments to their horizontal and vertical positions to ensure accurate pipeline connections. However, existing base structures are simple, mostly providing only basic support and unable to flexibly adjust the pipeline position. When fine-tuning the pipeline position is required, it usually requires a large amount of manual labor combined with hoisting equipment, which is not only inefficient and poses significant safety hazards, but also makes it difficult to guarantee the accuracy of pipeline installation. Furthermore, traditional bases are unable to effectively guarantee the stability and reliability of pipeline installation when facing complex terrain and uneven ground. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an adjustable base device for installing large-diameter pipelines. This solves the problems of difficulty in precisely adjusting the position and height of large-diameter pipelines, low installation efficiency, significant safety hazards, and poor installation stability in complex terrain. To achieve the above objectives, this utility model adopts the following technical solution:

[0004] An adjustable base device for installing large pipelines includes:

[0005] Two bases, with support feet fixedly connected to the bottom;

[0006] Two platforms are slidably connected to corresponding bases. At least one hydraulic jack and a support column are fixedly connected to the middle of the platform. The support block is used as a temporary support for the support pipe when the hydraulic jack is not working.

[0007] A hydraulic telescopic cylinder is mounted on one of the bases, with its two ends hinged to the base and the platform respectively, and is used to drive the platform to slide on the base.

[0008] Furthermore, two hydraulic jacks are provided, located on both sides of the support column.

[0009] Furthermore, the top of the hydraulic jack is fixedly connected to a top support for supporting the pipeline.

[0010] Furthermore, the top support is configured in an arc shape to match the pipe.

[0011] Furthermore, the base is fixedly connected to two parallel slide rails, and the bottom of the platform is fixedly connected to a slider that cooperates with the slide rails.

[0012] Furthermore, the slide rail is configured as an inverted convex shape, and the slider has a corresponding groove.

[0013] Furthermore, the two ends of the slide rail are detachably connected with limiting blocks to prevent the slider from derailing.

[0014] Furthermore, hydraulic support legs are fixedly connected to the four corners of the bottom of the base.

[0015] Furthermore, a laser emitter and a laser receiver for positioning are fixedly connected to adjacent sides of the base.

[0016] Furthermore, the laser emitter and laser receiver are provided in two sets arranged side by side.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The hydraulic jack enables precise control of the vertical height of the pipeline. The hydraulic telescopic cylinder drives the platform to slide on the base, which can accurately adjust the horizontal position of the pipeline. This solves the problem that traditional bases are difficult to adjust the position and height of the pipeline accurately, and meets the precision requirements of large-diameter pipeline installation.

[0019] 2. This device can quickly and conveniently adjust the position and height of pipelines, reducing the time and workload of manual operation in conjunction with hoisting equipment, and significantly improving the installation efficiency of large pipelines;

[0020] 3. The support column provides temporary support when the hydraulic jack is not in operation. The slide rail, slider and limit block ensure the safety of the platform sliding, prevent the device from malfunctioning or unexpected situations, and reduce safety hazards during the installation process.

[0021] 4. The hydraulic columns at the bottom of the base can automatically adjust the height according to the ground conditions, so that the device can remain stable on complex terrain and uneven ground, improving the versatility and adaptability of the device.

[0022] 5.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1-2 As shown in the figure, this utility model embodiment proposes an adjustable base device for installing large pipelines, including:

[0029] Two bases 1 are fixedly connected to the bottom with support feet 2. The support feet 2 can enhance the contact stability between the device and the ground, and can effectively support the weight of the entire device and pipe 14 under different ground conditions;

[0030] Two platforms 3 are slidably connected to corresponding bases 1. At least one hydraulic jack 4 and a support column 5 are fixedly connected to the middle of each platform 3. The support column 5 serves as a temporary support for the pipe 14 when the hydraulic jack 4 is not in operation. The sliding connection between the platform 3 and the base 1 allows for adjustment of the horizontal position of the pipe 14; the hydraulic jack 4 precisely controls the vertical height of the pipe 14; and the support column 5 provides temporary support when the hydraulic jack 4 is not in operation, ensuring the safety and stability of the installation process.

[0031] A hydraulic telescopic cylinder 6 is mounted on one of the bases 1, with its two ends hinged to the base 1 and the platform 3 respectively. It is used to drive the platform 3 to slide on the base 1. The hydraulic telescopic cylinder 6 can provide a stable and controllable driving force. Through its telescopic movement, the platform 3 can be precisely slid on the base 1, thereby adjusting the horizontal position of the pipe 14.

[0032] In this embodiment, as Figure 1 As shown, two hydraulic jacks 4 are provided, located on both sides of the support column 5. The two hydraulic jacks 4 can provide a more balanced support force, ensuring the stability of the pipe 14 in the vertical direction, and also facilitating more precise adjustment of the height of the pipe 14.

[0033] In this embodiment, as Figures 1-2As shown, a top support 7 is fixedly connected to the top of the hydraulic jack 4 to support the pipe 14. The top support 7 increases the contact area between the hydraulic jack 4 and the pipe 14, making the support more stable and reducing local pressure on the surface of the pipe 14.

[0034] In this embodiment, as Figures 1-2 As shown, the top support 7 is configured in an arc shape to match the pipe 14. The arc-shaped top support 7 can better fit the surface of the pipe 14, improve the stability and reliability of the support, and prevent the pipe 14 from rolling or shifting during installation.

[0035] In this embodiment, as Figures 1-2 As shown, two parallel slide rails 8 are fixedly connected to the base 1, and a slider 9 that cooperates with the slide rails 8 is fixedly connected to the bottom of the platform 3. The cooperation between the slide rails 8 and the slider 9 can provide guidance and support for the sliding of the platform 3, ensuring the stability and accuracy of the platform 3 during the sliding process.

[0036] In this embodiment, as Figure 2 As shown, the slide rail 8 is configured as an inverted convex shape, and the slider 9 has a corresponding groove. The mating structure of the inverted convex slide rail 8 and the grooved slider 9 can effectively prevent the slider 9 from detaching from the slide rail 8, thereby improving the safety and reliability of the device.

[0037] In this embodiment, as Figure 1 As shown, the slide rail 8 is detachably connected to two ends with limiting blocks 10 to prevent the slider 9 from derailing. The limiting blocks 10 can further limit the sliding range of the slider 9, ensuring that the platform 3 slides within the specified range and preventing damage to the device or safety accidents due to excessive sliding.

[0038] In this embodiment, as Figures 1-2 As shown, hydraulic support legs 11 are fixedly connected to the four corners of the bottom of the base 1. The hydraulic support legs 11 can automatically adjust their height according to the ground conditions, keeping the base 1 level, adapting to different terrain conditions, and improving the stability and versatility of the device.

[0039] In this embodiment, as Figures 1-2 As shown, a laser emitter 12 and a laser receiver 13 for positioning are fixedly connected to adjacent sides of the base 1. The laser emitter 12 and the laser receiver 13 can accurately measure and position the two bases 1. By emitting and receiving laser signals, the positional deviation of the pipe 14 can be monitored in real time, which facilitates timely adjustment and improves the installation accuracy of the pipe 14.

[0040] In this embodiment, as Figure 2As shown, the laser emitter 12 and laser receiver 13 are arranged in two sets side by side. The two sets of laser emitters 12 and laser receivers 13 can monitor and locate the position of the base 1 from multiple angles, further improving the accuracy and reliability of the positioning.

[0041] In this embodiment, the large pipe 14 is equipped with an adjustable base device. The base 1 is made of high-strength Q345B steel with a yield strength of not less than 345MPa and a tensile strength of 470-630MPa, ensuring that the base 1 has sufficient strength and stability to withstand the weight of the large pipe 14 and various forces during device operation. The support feet 2 at the bottom of the base 1 are made of the same steel material as the base 1, and are tapered in shape with a bottom diameter of 150mm and a height of 200mm, allowing for better ground penetration and enhanced grip.

[0042] Two parallel inverted convex slide rails 8 are fixedly connected to the base 1. The slide rails 8 are also made of Q345B steel, and their cross-sectional dimensions are: top width 40mm, bottom width 60mm, and height 30mm. A slider 9, which mates with the slide rails 8, is fixedly connected to the bottom of the platform 3. The slider 9 is made of 45# steel, with a yield strength of approximately 355MPa and a tensile strength of not less than 600MPa. The slider 9 has grooves corresponding to the inverted convex slide rails 8, and the dimensions of the grooves precisely match the slide rails 8, ensuring that the slider 9 can slide smoothly on the slide rails 8 without easily detaching. Limiting blocks 10, made of Q235B steel with a thickness of 20mm, are detachably connected to both ends of the slide rails 8 via bolts, effectively preventing the slider 9 from derailing.

[0043] Platform 3 has two hydraulic jacks 4 and a support column 5 fixedly connected to its upper center. The hydraulic jacks 4 are model RCH-50, with a rated pressure of 70MPa and a maximum lifting capacity of 50 tons, sufficient to lift the large-diameter pipe 14. An arc-shaped support 7 is fixedly connected to the top of each hydraulic jack 4. The support 7 is made of ZG270-500 cast steel, a material with good strength and toughness. The arc of the support 7 matches the outer diameter of the pipe 14, allowing it to fit tightly against the surface of the pipe 14 and provide stable support. The support column 5 is made of seamless steel pipe, material 20# steel, with an outer diameter of 108mm and a wall thickness of 8mm. When the hydraulic jacks 4 are not in operation, it reliably supports the pipe 14, ensuring safety during installation.

[0044] The hydraulic telescopic cylinder 6, model HSG-100 / 63, has an inner diameter of 100mm, a piston rod diameter of 63mm, and a maximum stroke of 300mm. It provides sufficient driving force to propel the platform 3 to slide on the base 1. The two ends of the hydraulic telescopic cylinder 6 are hinged to the base 1 and the platform 3, respectively. Its extension and retraction are controlled by a hydraulic system to achieve horizontal displacement adjustment of the platform 3.

[0045] Hydraulic feet 11 are fixedly connected to the four corners of the base 1. The hydraulic feet 11 are model SC-150, with a maximum extension stroke of 150mm. They can automatically adjust their height according to the ground conditions to keep the base 1 level. Two sets of parallel laser emitters 12 and laser receivers 13 are fixedly connected to the adjacent sides of the base 1. The laser emitters 12 are model LT-100, and the laser receivers 13 are model LR-100. The measurement accuracy can reach ±0.5mm, which can accurately measure and locate the installation position of the pipe 14.

[0046] In practical use, the device is first placed at the installation site, and the base 1 is automatically leveled using hydraulic column feet 11. During the adjustment process, the positions of the two bases 1 are adjusted using laser emitter 12 and laser receiver 13, and fine-tuned based on monitoring results until the two bases 1 are aligned and meet the installation requirements. Then, the large pipe 14 is placed on platform 3 and temporarily supported by support columns 5. The hydraulic jack 4 is activated to slowly raise the pipe 14 to a suitable height, while the platform 3 is slidable via hydraulic telescopic cylinder 6 to adjust the horizontal position of the pipe 14. The device in this embodiment can effectively improve the installation accuracy and efficiency of the large pipe 14, ensuring the safety and stability of the installation process.
