Description

Technical Field

[0001] This utility model relates to the technical field of welding construction platforms, specifically to a construction platform for welding the outer side of steel pipes on steep slopes. Background Technology

[0002] Welding the outer circumferential seam of pipe sections on slopes is a necessary step in the installation of pipelines on steep slopes. However, the slope of steep slopes makes it difficult to stably set up a construction platform, and the stability of the construction platform has a significant impact on the welding quality.

[0003] For large-diameter outer circumferential welds on steep slopes with an inner diameter greater than 2m and a slope greater than 15°, it is generally necessary to excavate a support plane on the slope to accommodate the construction platform before installing the construction platform that spans the pipeline. This results in a large amount of excavation, and when the pipeline is long, it is necessary to excavate the slope multiple times to form the support plane, which increases the workload and affects the overall construction cost and schedule. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the need for multiple excavations of the slope to form a support platform before the welding platform can be set up for the outer circumferential weld of the pipeline on a steep slope, which affects the overall construction cost and construction period. This invention provides a construction platform for welding the outer side of the steel pipe on a steep slope.

[0005] This utility model provides a construction platform for welding steel pipes on the outside of a steep slope, comprising: An operating platform, wherein the top surface of the operating platform is configured as an operating surface; The support mechanism includes at least two lattice columns; A connecting assembly, comprising a plurality of anchor bolts, wherein the anchor bolts are capable of providing a limiting connection to the bottom end of the lattice column.

[0006] This invention discloses a construction platform for welding the outer side of steel pipes on steep slopes. The operating platform provides an operating surface for welding the outer circumferential seam of the pipe. Workers can stand on the operating surface at the top of the platform to perform welding operations at the corresponding positions. At the same time, a support mechanism provides stable support for the operating platform. The support mechanism can be anchored to the slope surface through multiple anchor rods. The anchor rods can be fixed by drilling and implanting them. The anchoring force of the deep rock and soil of the slope is used to fix the grid column, which helps to reduce the amount of slope excavation. According to the actual situation, an appropriate number of anchor rods can be anchored in advance at suitable positions on the slope surface. When welding the outer circumferential seam of the pipe on steep slopes, the position of the construction platform can be adjusted in time according to the welding position, reducing the construction platform setup cost and time, and minimizing the impact of the construction platform erection on construction costs and schedule.

[0008] Preferably, the lattice column is detachably connected to the bottom surface of the operating platform.

[0009] Preferably, the bottom of the operating platform is provided with four lattice columns, which are symmetrically distributed in pairs to form a passageway for the pipes below the operating platform.

[0010] Preferably, the sidewall of the steel pipe pile is provided with an ear plate, and a horizontal connecting member is provided between adjacent steel pipe piles, wherein the horizontal connecting member is detachably connected to the ear plate.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0025] Unless otherwise specified, the terms "upper," "lower," "left," "right," "center," "inner," and "outer" used in the description of specific embodiments of this utility model to indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is usually placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, and for enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0026] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," "parallel," and "coaxial" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, parallel, or coaxial. Slight tilt or deviation is permissible, as long as it does not affect the normal function of the relevant component. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be perfectly horizontal; a slight tilt is acceptable. "Coaxial" means that two components are arranged as coaxially as possible, allowing them to move coaxially or approximately coaxially when their relative positions change. Alternatively, it can be simplified to mean that the corresponding device / component / element, when arranged in "horizontal," "vertical," "suspended," "parallel," or "coaxial" directions, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. For example, the deviation in the "coaxial" direction is controlled within 0.2-1mm, preferably within 0.2-0.5mm. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0027] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0028] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0029] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "provided with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0030] Example 1 like Figures 1-5As shown, a construction platform welded to the outside of a steel pipe on a steep slope includes an operating platform 1, a support mechanism, and a connecting component. The top surface of the operating platform 1 is constructed as an operating surface, where workers can stand and perform related operations. The top of the support mechanism is used to support the operating platform 1, and the bottom is used to fix it on the inclined slope, so that the operating platform 1 can be stably supported above the pipe 10. The connecting component is used to limit and fix the support mechanism on the slope.

[0031] In one or more implementations, such as Figure 1 As shown, the support mechanism includes at least two lattice columns 2, which are arranged opposite to each other, forming a passageway 4 for the pipe 10 between the two opposite lattice columns 2, so that the construction platform is straddling the pipe. The connecting components include several anchor rods 3, which are used to limit the connection of the bottom end of the lattice column 2.

[0032] In an optional implementation, the anchor rod 3 can be a hollow grouting anchor rod 3, which is directly inserted into the slope after drilling and grouting is performed simultaneously. This eliminates the need for large-area excavation of the slope and pouring of a reinforced concrete foundation, and can quickly provide a position for the construction platform to be installed on the slope, thus achieving rapid fixation of the construction platform on the slope.

[0033] In an optional embodiment, each lattice column 2 includes at least three steel pipe piles 21, and each steel pipe pile 21 includes at least two detachably connected pipe segments 22. The arrangement of the steel pipe piles 21 ensures the structural stability of a single lattice column 2, allowing the operating platform 1 to be stably set on the slope through the support of the lattice columns 2. At the same time, by setting the steel pipe piles 21 as a combination of multiple pipe segments 22, pipe segments 22 of different lengths can be connected according to the slope of the slope to form lattice columns 2 of different heights. This allows the operating platform 1 to be supported on the inclined slope through steel pipe piles 21 of different lengths, forming a relatively stable operating surface.

[0034] In an optional implementation, the number of steel pipe piles 21 that make up the lattice column 2 can be adjusted to 3-4 piles according to the actual situation to ensure the structural strength of a single lattice column 2.

[0035] In an optional embodiment, the lattice column 2 is detachably connected to the bottom surface of the operating platform 1. This allows the lattice column 2 and the operating platform 1 to be separated according to actual conditions, facilitating the installation of lattice columns 2 at different heights and enabling the construction platform to be used stably on slopes of varying inclinations.

[0036] In an alternative implementation, the detachable connection can be a combination of flanges and bolts.

[0037] In an optional embodiment, four lattice columns 2 can be installed at the bottom of the operating platform 1, with the four lattice columns 2 symmetrically distributed in pairs, forming a passageway 4 for the pipe 10 below the operating platform 1. In use, as... Figure 4 As shown, by simply setting up lattice columns 2 on both radial sides of the pipe 10 and connecting them to the top operating platform 1, the construction platform on the steel pipe on the steep slope section can be quickly set up, so that the construction platform spans above the pipe 10 to be welded.

[0038] In an optional embodiment, the sidewall of the steel pipe pile 21 is provided with an ear plate 23, and a horizontal connecting member 24 is provided between adjacent steel pipe piles 21. The horizontal connecting member 24 is detachably connected to the ear plate 23. The structural strength of each lattice column 2 is strengthened by the horizontal connecting member 24, and the connection between the horizontal connecting member 24 and the ear plate 23 of different heights can be adjusted according to the actual situation to achieve different structural strengthening effects.

[0039] In an optional embodiment, the horizontal connecting member 24 can be a steel member such as angle steel or channel steel, and can be connected at different positions on adjacent steel pipe piles 21 according to the actual situation, so as to maximize the overall support stability of the construction platform.

[0040] In optional implementations, such as Figure 2 As shown, the operating platform 1 includes a frame base plate 11, on which a walkway 12 is laid. The frame base plate 11 has a perforated section 13. The bottom surface of the frame base plate 11 is used to connect with the lattice column 2, and the top is provided with a standing position for workers through the walkway 12. During construction, workers can stand on the walkway 12 and perform operations such as welding on the corresponding positions of the pipes 10 from the perforated section 13.

[0041] In an optional embodiment, the frame base plate 11 can be a steel grating component, the walkway plate 12 can be a patterned steel plate, and the hollow part 13 can be formed by paving the walkway plate 12 in a ring on the frame base plate 11, thus creating a hollow space in the middle area of ​​the frame base plate 11 that is convenient for construction.

[0042] In an optional embodiment, the operating platform 1 is equipped with a guardrail 6, which is detachably connected to the frame base plate 11. This guardrail 6 ensures the safety of the workers.

[0043] In one or more implementations, such as Figure 3 As shown, a hanging basket 5 can be detachably connected to two adjacent lattice columns 2 along the longitudinal direction of the pipeline 10. The hanging basket 5 provides more standing positions for workers, enabling smooth welding of the circumferential seams on the pipeline 10. At the same time, the connection position of the hanging basket 5 on the lattice column 2 can be adjusted according to the actual situation, changing the height of the hanging basket 5 to achieve the construction of welds at different height positions.

[0044] In an optional embodiment, the hanging basket 5 can be connected to the steel pipe pile 21 that makes up the lattice column 2 by means of a clamping member, or it can be connected to the lattice column 2 by other fixable means.

[0045] In an optional embodiment, a ladder 7 is detachably connected to at least one lattice column 2. Workers can access the work surface by climbing the ladder 7.

[0046] In an alternative implementation, the ladder 7 can be a rope ladder.

[0047] In one or more implementations, such as Figure 5 As shown, it may also include a traction mechanism, which includes a limiting component 8 and a cable 9. One end of the cable 9 is connected to the limiting component 8, and the other end can be detachably connected to the support mechanism. The limiting component 8 can limit and fix the support mechanism to the slope or the top of the slope. By adding a traction mechanism to provide upward tension along the slope to the support mechanism, the overall slippage of the construction platform along the slope is prevented, further ensuring the overall safety of the construction platform. At the same time, since the operating platform 1 is kept stable by the traction mechanism, the degree of limiting and fixing at the bottom of the lattice column 2 and the number of anchor bolts 3 can be appropriately reduced, thereby further reducing the amount of slope excavation required to fix the lattice column 2 during construction, improving construction efficiency and reducing construction costs.

[0048] In an optional embodiment, the cable 9 can be a steel wire rope, and the limiting member 8 can be an anchor rod 3, a support, or other structure that can limit and fix the position.

[0049] In an optional embodiment, a connecting part can be provided on the operating platform 1 or the support mechanism, and the cable 9 can be detachably connected to the connecting part. The connecting part can be a perforated plate welded to one side of the operating platform 1 or one side of the lattice column 2, and the cable 9 can be fastened to the connecting part to realize the traction limit of the construction platform.

[0050] This embodiment describes a construction platform for welding the outer side of a steel pipe on a steep slope. The operating platform 1 provides an operating surface for welding the outer circumferential seam of the pipe 10. Workers can stand on the operating surface at the top of the operating platform 1 to perform welding operations at the corresponding positions. At the same time, a support mechanism provides stable support for the operating platform 1. The support mechanism can be anchored to the slope surface by multiple anchor rods 3. The anchor rods 3 can be fixed by drilling and implanting. The anchoring force of the deep rock and soil of the slope is used to fix the grid column 2, which helps to reduce the amount of slope excavation. According to the actual situation, an appropriate number of anchor rods 3 can be anchored in advance at suitable positions on the slope surface. When welding the outer circumferential seam of the pipe 10 on a steep slope, the position of the construction platform can be adjusted in time according to the welding position, reducing the construction platform setup cost and time, and reducing the impact of the construction platform erection on construction costs and schedule.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
