Technical Field

[0001] The utility model relates to the technical field of support devices, and more specifically, to a temporary support device for installing a self-supporting overhead metal pipeline. Background Art

[0002] During the installation of self-supporting overhead metal pipelines, due to limitations in pipeline design and construction site conditions, the pipeline splicing welds inevitably occur in the overhead area between the overhead pipeline piers, which greatly complicates on-site pipeline welding. Furthermore, due to the heavy weight of metal pipelines, their lifting, support, and installation pose certain risks. Using a truck crane for long-term lifting is costly and difficult to accurately control, hindering docking and welding operations. Therefore, a simple, detachable, and adjustable temporary support that can accommodate both pipeline positioning and jacking operations is urgently needed, providing a technical solution for overhead pipeline positioning, welding, and other aerial operations.

[0003] In response to the above needs, the utility model proposes a temporary support for the installation of self-supporting overhead metal pipes, which provides stable, reliable and safe technical conditions and operating platform for the precise positioning, docking and welding of pipes during the installation process.

[0023] The control method of the electrical components in the present invention is controlled by an external controller matched therewith, and the control circuit can be realized by simple programming by technicians in this field. It belongs to the common knowledge in this field and is only used without improvement. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0024] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0025] As attached Figure 1 To the attached Figure 3 As shown, an embodiment of the utility model provides a temporary support device for the installation of a self-supporting overhead metal pipe, including a support frame 1, a plurality of rubber rollers 2 are fixedly connected to the bottom edge of the support frame 1, a plurality of upper limiting angle steels 5 are fixedly connected to the bottom center of the support frame 1, a pipe support 3 is fixedly connected to the top of the support frame 1, a jack 7 is installed at the bottom of the upper limiting angle steel 5, the support frame 1 is a rectangular steel frame formed by overlapping channel steels, a plurality of ear plates 4 are fixedly connected on both sides of the support frame 1, a hand hoist 6 is installed inside the ear plate 4, a lower limiting angle steel 8 is installed at the bottom of the jack 7, the connecting beam between the two fulcrum columns of the support frame 1 is telescopic, and the rubber roller 2 moves along the vertical direction of the pipe.

[0026] During the installation of self-supporting overhead metal pipelines, the welds will be arranged in the overhead section between adjacent supports of the pipeline. Therefore, a temporary support is required during the pipeline installation construction to provide a stable and safe operating platform for pipeline welding and splicing.

[0027] In response to the above needs, the present invention proposes the temporary support, which is easy to install and disassemble, simple to operate, and has the ability to be accurately positioned and reused.

[0028] The vertical displacement adjustment of the utility model is achieved through the stroke of the jack 7.

[0029] The support point spacing of the utility model is achieved by adjusting the expansion and contraction of the crossbeam.

[0030] Creatively add limiting angle steel, hand hoist 6 and other stabilizing devices to ensure the safety and reliability of the support during use.

[0031] The main structure of the temporary support described in the utility model is a rectangular steel frame formed by overlapping channel steels; a rubber wheel that can move along the vertical direction of the pipeline is set at the bottom end of the frame; ear plates 4 are welded on the side edges of the pillars of the temporary support for connecting hand hoists 6; and the lifting force points of the temporary support are provided with limiting channel steels.

[0032] In addition, the present invention also requires two fixing points to be provided on its supporting platform, which are used to fix the temporary support after the pipeline positioning is completed.

[0033] The use process of the temporary support described in the present invention is: site leveling (if the pipeline design elevation is large, a stable platform can be set up first) - support positioning - installation of jack 7 - pipeline hoisting - pipeline jacking - installation of hand hoist 6 - pipeline welding - support disassembly.

[0034] The details are as follows:

[0035] Site leveling: Before installing the pipeline, the site must be leveled and the foundation bearing capacity must meet the requirements. If the pipeline installation elevation is high and the stroke of the temporary support jack 7 cannot meet the lifting requirements, a platform must be set up to raise the temporary support installation elevation and install the temporary support on the platform.

[0036] Temporary support positioning: Use rollers to move the support frame 1 to the preset position of the pipeline and then lock the rollers;

[0037] Install jack 7: The bearing capacity of the platform where jack 7 is placed should meet the calculation requirements. Place the top shaft end of jack 7 under the limit channel steel of the upper structure beam;

[0038] Pipeline jacking: Start the hydraulic device, wait until the stroke of the jack 7 is stable, remove the lifting machinery, lift the pipeline to the temporary support, untie the lifting device after it is stable, and use the jack 7 to accurately position the pipeline interface;

[0039] Install the chain hoist 6: After the pipeline is positioned and stabilized, lock the hydraulic device of the jack 7 and observe the docking condition of the pipeline interface. If it does not meet the welding requirements, repeat the above steps. If it does meet the welding requirements, use the chain hoist 6 connected to the support side lug 4 and the platform fixed point to tighten it to form a stable structural system;

[0040] Pipeline welding construction work;

[0041] The temporary support is disassembled.

[0042] Among them, it is important to emphasize that:

[0043] The ground in the temporary support installation area should be leveled and screed with C25 concrete.

[0044] The components of the temporary support frame are: channel steel, double-jointed channel steel, steel pipe, end plate, etc.

[0045] Temporary supports need to be monitored with the help of total stations and laser vertical meters.

[0046] In order to meet the construction requirements of high-altitude welding operations for pipeline splicing, steel supports are arranged to temporarily support the pipe fittings to be spliced, and a high-altitude welding operation platform is provided.

[0047] The temporary support is made of [20a channel steel and Φ500×10 round steel spiral welded pipe, and the top surface is paved with 5mm thick checkered steel plate (which is intermittently welded to the main structure, the fillet weld height is 5mm, the length is 300mm and the spacing is 200mm). The jack 7 is set at the intersection of the rods, and its bottom is welded to the checkered steel plate (the fillet weld height is 5mm, welded around the four sides, and 50×5 angle steel is used to weld around the four sides to strengthen the bottom of the jack 7). The upper part of the jack 7 is stuck in the channel steel under the crossbeam of the pipe support 3 to constrain its horizontal displacement.

[0048] Ear plates 4 are respectively provided at the ends of the four legs of each set of pipe supports 3, and ear plates 4 are also provided at the corresponding positions of the steel platform. A 1.0t manual hoist is used for tensioning and connection to ensure the stability of the pipe supports 3.

[0049] A temporary pipe support 3 with a height adjustable by a jack 7 (16 tons) is provided on the top of the platform to facilitate removal of the temporary support after the pipe splicing and welding is completed.

[0050] The temporary support area was leveled and compacted before being poured with a 150mm thick C30 concrete cushion. The column base was secured to the ground with six M24 mechanical anchor bolts, and the ground's bearing capacity met the requirements.
