[0002] A gas pipeline is a special pipeline for transporting combustible gases, usually used to transport combustible gases such as natural gas and liquefied gas from a supply source to user ends, such as households, industrial and commercial sites. Among them, steel pipes are one of the commonly used pipelines for gas transportation. When transporting gas over a relatively long distance, since the diameter of the steel pipe is large and heavy, if the length of the steel pipe is long, it is not convenient for the transportation and installation of the steel pipe. Usually, steel pipes of the same specification are produced in a production workshop, and then multiple sections of steel pipes are transported to the installation point and welded into a longer gas pipeline.

[0038] Please refer to Figures 1-5 , the present utility model provides a technical solution: a pipeline positioning device for gas engineering, including a support beam 1. Two lifting blocks are provided below both ends of the support beam 1. Both of the two lifting blocks are slidably connected to the support beam 1 along the length direction of the support beam 1, and the planes of the sliding trajectories of the two lifting blocks are parallel to each other;

[0039] Both of the two lifting blocks are in a wedge shape with a smaller upper part and a larger lower part, and the opposite side surfaces of the two lifting blocks are inclined from top to bottom;

[0040] A driving assembly is provided between the two lifting blocks and the support beam 1 for driving the two lifting blocks to approach or move away from each other.

[0041] By providing two lifting blocks in a wedge shape and slidably connecting the lifting blocks to the support beam 1, when the two lifting blocks approach each other, the lower edge of the inclined surface of the lifting block can smoothly insert into the gap between the steel pipe and the ground, and the two inclined surfaces of the two lifting blocks are in contact with the outer circular surface of the steel pipe. As the two lifting blocks approach each other, the steel pipe is pushed vertically upward by the two inclined surfaces of the two lifting blocks, so that the steel pipe is lifted to a suspended state and separated from the ground contact, providing the necessary operating space for welding the steel pipe.

[0042] Meanwhile, the two lifting blocks support the steel pipe and restrict the free swing of the steel pipe, reducing the safety risks caused by the swing of the steel pipe.

[0043] In this embodiment: a strip-shaped hole 11 extending in the length direction of the support beam 1 is provided on the top surface of the support beam 1, and two sliders 12 are slidably fitted in the strip-shaped hole 11;

[0044] The two sliders 12 are respectively fixedly connected to the tops of the two lifting blocks.

[0045] By respectively fixedly connecting the tops of the two lifting blocks to the two sliders 12, and embedding the sliders 12 into the strip-shaped hole 11 and slidably connecting them, the lifting block can slide in a single degree of freedom along the length direction of the support beam 1, so that the inclined surface of the lifting block maintains a stable inclined state, facilitating stable contact with the outer circular surface of the steel pipe and stably lifting and supporting the steel pipe.

[0046] In this embodiment: the driving assembly includes a lead screw 13 extending in the length direction of the strip-shaped hole 11 and a motor 3. The two ends of the lead screw 13 respectively penetrate through the two side walls of the strip-shaped hole 11 and extend out of the strip-shaped hole 11, and are rotatably fitted;

[0047] The two sliders 12 are strung on the two ends of the lead screw 13 and are connected by screw threads, and the screw threads at the two ends of the lead screw 13 have opposite helix directions;

[0048] The motor 3 is fixedly connected to one end of the support beam 1, and the output end of the motor 3 is fixedly connected to one end of the lead screw 13.

[0049] The motor 3 is used to provide power for the rotation of the lead screw 13. By providing two sections of external threads with opposite helix directions at the two ends of the lead screw 13, when the lead screw 13 rotates, the external threads at the two ends push the two sliders 12 to approach or move away from each other, so as to achieve the purpose of lifting or lowering the steel pipe.

[0050] In this embodiment: scale lines 16 evenly distributed along the length direction are engraved on the top surface of the support beam 1.

[0051] When welding two steel pipes, the positioning devices are placed on both steel pipes, and the number of the positioning devices on each steel pipe can be one or more. The positioning devices are used to lift the steel pipes off the ground and keep them horizontal. Observe the readings on the scale lines 16 corresponding to the positions of the sliders 12 in the positioning devices after the two steel pipes are lifted, and adjust the readings in the positioning devices on the two steel pipes to be the same, so that the two steel pipes are at the same height, facilitating the alignment and positioning of the two steel pipes, and finally completing the welding work.

[0052] In this embodiment: The top end of the slider 12 protrudes outside the opening of the strip-shaped hole 11 and is fixedly connected with a marking strip 14. The marking strip 14 is perpendicular to the support beam 1, and the end extends upward above the scale line 16.

[0053] By providing the marking strip 14 at the top end of the slider 12 and extending the end of the marking strip 14 above the scale line 16, it is convenient to directly read the reading of the position of the slider 12 corresponding to the scale line 16.

[0054] In this embodiment: The two lifting blocks include a first lifting block 21 and a second lifting block 22. A groove 211 extending through in the length direction of the support beam 1 is formed on the bottom surface of the first lifting block 21;

[0055] When the first lifting block 21 and the second lifting block 22 approach each other, the second lifting block 22 can be inserted into the groove 211.

[0056] By forming the groove 211 on the bottom surface of the first lifting block 21 and making the thickness dimension of the second lifting block 22 smaller than the width dimension of the groove 211, a part of the second lifting block 22 can be embedded into the groove 211 to overlap with the first lifting block 21, so as to increase the stroke of the first lifting block 21 and the second lifting block 22 on the support beam 1. When the second lifting block 22 is embedded into the first lifting block 21, the intersection position of the inclined surfaces of the first lifting block 21 and the second lifting block 22 is raised. Since the inclination angles of the inclined surfaces of the first lifting block 21 and the second lifting block 22 are fixed and unchanged, when the intersection line rises, the height of the corresponding steel pipe also increases, so as to increase the height by which the steel pipe is lifted.

[0057] In this embodiment: Support plates 4 are provided on both opposite sides of the two lifting blocks. The top ends of the two support plates 4 are respectively fixedly connected to both ends of the support beam 1;

[0058] A pressing strip 5 parallel to the support beam 1 is provided between the two support plates 4. Both ends of the pressing strip 5 are respectively slidably connected to the two support plates 4, and the plane of the sliding track is parallel to the plane of the sliding track of the lifting block on the support beam 1.

[0059] The support plate 4 is used to connect the support beam 1 and the bottom surface. The support beam 1 is supported by the support plate 4 so that the positioning device stands stably on the ground. After the two lifting blocks lift the steel pipe to the target height, the lower pressure bar 5 is pushed to slide downward on the support plate 4 so that the bottom surface of the lower pressure bar 5 contacts and abuts against the outer cylindrical surface of the steel pipe. The steel pipe is clamped and fixed by the two lifting blocks and the lower pressure bar 5 to limit the steel pipe from rotating and tipping on the positioning device.

[0060] In this embodiment: the bottom surface of the support plate 4 is coplanar with the bottom surface of the lifting block.

[0061] The bottom surface of the support plate 4 and the bottom surface of the lifting block are set to be coplanar, so that the bottom surface of the support plate 4 and the bottom surface of the lifting block are in contact with the ground together, the pressure on the support plate 4 is shared, and the contact points between the positioning device and the ground are dispersed, so that the positioning device stands stably on the ground, reducing the risk of the positioning device tipping over, so as to stably support the steel pipe.

[0062] In this embodiment: the two sides of the two support plates 4 are provided with sliding grooves 41 extending in the vertical direction, and the two ends of the lower pressing strip 5 are respectively inserted into the two sliding grooves 41 and slide in cooperation;

[0063] A height adjustment component for adjusting the height of the lower pressing bar 5 is provided between the lower pressing bar 5 and the support beam 1 .

[0064] In this embodiment: a threaded hole 15 penetrating the support beam 1 is opened on the top surface of the support beam 1, and the height adjustment assembly includes a bolt 6, the threaded end of the bolt 6 penetrates the threaded hole 15 and is inserted into the lower pressure strip 5 and rotatably cooperates with the lower pressure strip 5, and the bolt 6 is connected to the threaded hole 15 by threaded cooperation.

[0065] The slide groove 41 is provided on the support plate 4, and the end of the lower pressure strip 5 is inserted into the slide groove 41 to limit the free rotation of the lower pressure strip 5. When adjusting the height of the lower pressure strip 5, the bolt 6 is rotated forward or reversely, and the bolt 6 moves downward or upward under the push of the internal thread of the threaded hole 15; at the same time, the bolt 6 rotates on the lower pressure strip 5 and drives the lower pressure strip 5 to move downward or upward together, so as to achieve the purpose of adjusting the height of the lower pressure strip 5.

[0066] Among them, the specific model of motor 3 is Demark 180M-35015E-E.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
