[0002] Gas is one of the three major energy sources in the world. With the continuous development of the times, people's lives cannot be separated from gas. Gas is transported through pipelines. The installation of gas pipelines may not be visible in life, but the process of fixing gas pipelines is very important. A good fixing device can effectively prevent gas leakage and ensure the smoothness of gas during transportation.

[0003] When installing a gas pipeline, it is necessary to use a pipeline positioning device to fix the gas pipeline. However, according to some existing positioning devices, such as U-shaped stirrups, some U-shaped stirrups may need to be replaced with U-shaped stirrups of another size when the corresponding pipeline size changes, resulting in the need to carry a variety of U-shaped stirrups of different sizes for use when installing the gas pipeline. In addition, during the positioning process, due to the effect of air pressure, the sudden rise and fall of air pressure inside the gas pipe during gas transportation may cause vibration between the gas pipeline and the U-shaped stirrup, causing the U-shaped stirrup to affect the tightness of the gas pipeline clamp; therefore, the above problems need to be improved.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Example: See Figure 1-5 A positioning device for gas pipeline installation in the utility model comprises a lower plate seat 1, both sides of the top surface of the lower plate seat 1 are longitudinally opened with sliding grooves 11, the front and rear ends of the sliding grooves 11 are slidably provided with support sliders 2, the top surfaces of the support sliders 2 are installed with clamping arc plates 6, and the notches of the two clamping arc plates 6 installed on each sliding groove 11 are arranged opposite to each other; the clamping arc plates 6 can be effectively clamped during the gas transmission process, and the sliding groove 11 is also provided with an adjustment component for moving the two support sliders 2 in the same notch, and the adjustment component can be adjusted according to the required size of the pipeline.

[0021] In the present invention, the clamping arc plate 6 is fixed on the supporting slide block 2 by screws; the bottom of the inner arc surface of the clamping arc plate 6 is in an inclined shape. Through the inclined shape of the bottom surface, the pipeline can be lifted from the table surface.

[0022] In the utility model, an anti-skid sheet 7 is installed on the inner arc surface of the clamping arc plate 6, and a plurality of small friction bumps 8 are equidistantly arranged on the inner arc surface of the anti-skid sheet 7. The plurality of small friction bumps 8 effectively increase the contact area between the small friction bumps 8 and the pipeline, and the arrangement of the small friction bumps 8 can effectively increase the friction between the pipeline and the pipeline, thereby achieving an anti-skid effect.

[0023] In the utility model, the adjustment assembly includes bearing seats 9 arranged at both ends of the sliding groove 11 and a bidirectional screw rod 3 rotatably arranged between the bearing seats 9. The front end surface of the support slider 2 is longitudinally provided with a threaded hole matched with the bidirectional screw rod 3, and the rod body of the bidirectional screw rod 3 passes through the threaded hole; and the two support sliders 2 in the same sliding groove 11 are respectively located on the front end rod body and the rear end rod body of the bidirectional screw rod 3. By adjusting the bidirectional screw rod 3, the distance between the clamping arc plates 6 can be controlled.

[0024] In the utility model, a cross slot 10 is provided on the front end surface of the bidirectional screw rod 3. The bidirectional screw rod 3 can be rotated by the cooperation of the cross slot and 10 cross screwdrivers.

[0025] In the present invention, the lower plate seat 1 is provided with a screw hole 4, and a reinforcing rib 5 is left at the upper end of the lower plate seat 1. The reinforcing rib 5 on the lower plate seat 1 can effectively improve the tensile strength of the lower plate seat 1.

[0026] Working principle: When the utility model is used, the lower plate seat 1 is fixed to the mounting plate by screws, and a sliding groove 11 is opened on the lower plate seat. Under the action of the bearing seat 9, the bidirectional screw rod 3 rotates to adjust the distance between the two clamping arc plates 6, so as to clamp the pipeline. The bidirectional screw rod 3 can also be adjusted according to the pipeline size to meet the required size requirements and then clamp it. The anti-slip sheet 7 on the inner wall of the clamping arc plate 6 can effectively prevent the movement of the pipeline during positioning, and effectively ensure the positioning of the pipeline. The inclined slider under the clamping arc plate 6 can perform an initial positioning of the pipeline when the pipeline is placed, which better ensures that there will be no errors in the clamping process and that the pipeline is concentric with the clamping arc plate.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
