Moreover, in actual use, the range of movement is limited, and it is difficult to meet the positioning needs of the pipeline at various complex angles. When the pipeline needs to be installed at a large angle or in a narrow space, these devices often cannot work effectively. UTILITY MODEL CONTENT

[0024] The embodiments of the present application will be described below by specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] As Figures 1-3 shown, a pipeline positioning device for gas engineering comprises an angle steel 1, a rocker 2, a lower clamp 4 and an upper clamp 5; a long hole 11 is formed in the horizontal plate of the angle steel 1, the rocker 2 is composed of an upper vertical rod 21, a lower vertical rod 22 and a horizontal rod 23 connecting the two, the upper vertical rod 21 and the lower vertical rod 22 are both provided with threads; the lower vertical rod 22 passes through the long hole 11, two back nuts 3 are respectively located above and below the horizontal plate of the angle steel 1 and are threadedly connected with the lower vertical rod 22, so as to fix the rocker 2 on the angle steel 1; the lower clamp 4 is provided with a screw hole in the middle, which is threadedly connected with the upper end of the upper vertical rod 21 and is fastened by the back nut 3; the upper clamp 5 is fixedly connected with the lower clamp 4 through a bolt 6, thereby realizing the positioning of the gas pipeline.

[0026] The pipeline positioning device for the gas engineering is mainly realized by adjusting and positioning in the following ways:

[0027] Height adjustment principle: the height position of the lower clamp 4 and the upper clamp 5 is adjusted by the threaded cooperation of the back nut 3 and the lower vertical rod 22 and the design of the long hole 11.

[0028] Operation process: when the height position of the lower clamp 4 and the upper clamp 5 needs to be adjusted, loosen the two back nuts 3 located on the horizontal plate of the angle steel 1. Since the lower vertical rod 22 passes through the long hole 11, the lower vertical rod 22 can move up and down in the long hole 11 at this time. After moving the lower vertical rod 22 to the appropriate height, tighten the two back nuts 3 again to tightly abut against the horizontal plate of the angle steel 1, so as to fix the rocker 2 at the height position. Since the lower clamp 4 is threadedly connected with the upper end of the upper vertical rod 21, the height of the lower clamp 4 and the upper clamp 5 is also determined, so as to realize the positioning of the pipeline in the height direction.

[0029] Distance adjustment principle from the wall: the distance of the lower clamp 4 and the upper clamp 5 from the wall is adjusted by changing the angle between the horizontal rod 23 and the angle steel 1.

[0030] Operation process: loosen the two back nuts 3 first, and then the rocker 2 can rotate in the long hole 11 around the lower vertical rod 22. Rotate the rocker 2 to make the horizontal rod 23 and the angle steel 1 form different angles within the long hole 11. With the change of the angle of the horizontal rod 23, the distance of the lower clamp 4 and the upper clamp 5 from the wall connected with the upper vertical rod 21 will also change accordingly. When the appropriate distance is adjusted, tighten the back nuts 3 to fix the rocker 2 at the position, so as to realize the positioning of the pipeline in the direction from the wall.

[0031] Adaptation to the axial adjustment principle of the gas pipeline: the lower clamp 4 and the upper clamp 5 can better fit the axial direction of the gas pipeline by adjusting the angle of the lower clamp 4 and the upper vertical rod 21 through the threaded connection of the lower clamp 4 and the upper vertical rod 21.

[0032] Operation process: loosen the back nuts 3 for fastening the lower clamp 4 and the upper vertical rod 21, and then the lower clamp 4 can rotate around the upper vertical rod 21. According to the actual axial direction of the gas pipeline, rotate the lower clamp 4 to make it adapt to the axial direction of the pipeline. After adjusting the angle, tighten the back nuts 3 again to fix the lower clamp 4 at the angle position, and the upper clamp 5 is fixedly connected with the lower clamp 4 through the bolt 6, so as to realize the positioning of the pipeline in the axial direction and ensure that the pipeline can be stably fixed at the appropriate position.

[0033] In another preferred embodiment, the lower clamp 4 and the upper clamp 5 have multiple specifications to adapt to gas pipes of different outer diameters; in order to facilitate threaded connection with the rocker 2, they all adopt the same specification of screw holes. The lower clamp and the upper clamp have multiple specifications to adapt to gas pipes of different outer diameters, and the same specification of screw holes facilitates connection with the rocker, thereby enhancing the versatility and installation convenience of the device.

[0034] In another preferred embodiment, the bolt 6 is a T-shaped bolt; the lower clamp 4 is provided with a lower circular groove 41 at both ends, which is downwardly open and adapted to the short horizontal rod 61 of the T-shaped bolt 6; the lower clamp 4 and the upper clamp 5 are also provided with outer circular grooves 42 at both ends, which are outwardly open and adapted to the screw rod 62 of the T-shaped bolt 6. The T-shaped bolt is used in combination with the lower circular groove of the lower clamp and the outer circular grooves of the lower clamp and the upper clamp, so that the short horizontal rod of the T-shaped bolt can be self-positioned, and the upper clamp is also convenient to assemble and disassemble, thereby improving the installation efficiency and stability.

[0035] In another preferred embodiment, the length of the upper vertical rod 21 is less than the length of the lower vertical rod 22. The length of the upper vertical rod is less than the length of the lower vertical rod, which can make the gravity center of the device more reasonable and more stable during installation and use, and can also facilitate operation and layout in a specific space.

[0036] In another preferred embodiment, the middle part of the lower clamp 4 extends downward to form a circular truncated cone 44, and screw holes are provided on the circular truncated cone 44 and the body of the lower clamp 4. The middle part of the lower clamp extends downward to form a circular truncated cone and the screw holes are provided, which increases the depth of the screw holes, improves the structural strength of the connection part between the lower clamp and the upper vertical rod, and prolongs the service life of the device.

[0037] In another preferred embodiment, the nut 63 adapted to the bolt 6 is a nut with a flat washer. The nut adapted to the bolt has a flat washer, which can reduce the wear between the nut and the connecting piece, increase the contact area, make the connection more tight and stable, and prevent loosening.

[0038] In another preferred embodiment, at least two expansion screw holes 12 are arranged on the vertical plate of the angle steel 1. The vertical plate of the angle steel has at least two expansion screw holes arranged in an up-down manner, which facilitates the use of expansion screws to firmly fix the angle steel on the wall surface, thereby improving the stability and safety of the device as a whole.

[0039] In another preferred embodiment, a triangular reinforcing rib 13 is arranged between the vertical plate and the flat plate of the angle steel 1. The triangular reinforcing rib arranged between the vertical plate and the flat plate of the angle steel enhances the structural strength and load-bearing capacity of the angle steel, so that the device can better withstand the weight of the pipe and external forces.

[0040] In another preferred embodiment, a flat washer and a spring washer are additionally arranged between the back nut 3 and the horizontal plate of the angle steel 1, or between the back nut 3 and the lower clamp 4. The flat washer can disperse pressure and protect the contact surface, and the spring washer can provide elastic pre-tightening force to prevent the nut from loosening and ensure the reliability of the connection.

[0041] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
