Description

Technical Field

[0001] The utility model relates to a pipeline marking instrument with an elevation angle measurement function, belonging to the field of pipeline marking instruments. Background Art

[0002] During the construction and maintenance of oil and gas pipelines, accurately determining the installation location of equipment is crucial. Ensuring that the equipment is installed vertically is a key requirement, directly impacting the safe operation and efficiency of the pipeline system. When installing certain valves or instruments, the installation angle must be adjusted based on the pipeline's elevation to ensure proper operation and smooth fluid flow. Imagine a natural gas pipeline that requires the installation of a pressure monitoring instrument. Failure to accurately measure the pipeline's elevation and adjust the instrument's installation angle accordingly could lead to deviations in the monitoring data, affecting accurate assessments of pipeline pressure and potentially posing safety risks.

[0003] The patent number is CN220051824U, and the patent name is a utility model patent for a pipe oblique insertion marking and positioning device. Although it is easy to operate, has accurate positioning, and can improve the marking and positioning efficiency, in actual use, due to the different diameters of the pipes, it is very likely that the base will be installed unreliably, resulting in changes in the point position, so it is necessary to improve it.

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0015] Specific implementation method 1: Figure 1-5As shown, this embodiment records a pipeline marking instrument with an elevation angle measurement function, including a saddle plate 1; the upper end of the saddle plate 1 is hinged with an elevation plate 2 through a hinge 9; the upper end of the elevation plate 2 is fixedly connected to a dual-axis electronic level 7 and two bubble levels 5; the upper end of the elevation plate 2 is also fixedly connected to a bearing seat 3; the side of the bearing seat 3 is connected to a shaft 9 through a bearing; a circular hole perpendicular to its central axis is provided on the outer circumference of the shaft 9, and a screw rod Ⅰ8 slidingly matched with the shaft 9 is provided in the circular hole; a positioning nut 10 is threadedly connected to the screw Ⅰ8, and the positioning nut 10 is threadedly connected to the screw Ⅰ8. 0 is located at the upper end of the shaft 9, and the lower end of the screw rod I8 is fixedly connected to the lead weight 4. The elevation plate 2 is also provided with a vertical through-hole, in which a guide punch 15 is installed for sliding engagement with the through-hole. The saddle plate 1 is provided with a vertical through-hole 101 for sliding engagement with the guide punch 15. A fixed cylinder 11 is fixedly connected to the side of the saddle plate 1, and a sliding rod 12 is installed on the side of the fixed cylinder 11 for sliding engagement with the fixed cylinder 11. The sliding rod 12 is threadedly connected to the sliding rod 12. The lower end of the screw rod II 13 is fixedly connected to the support plate 14. The side of the saddle plate 1 is also provided with an angle adjustment mechanism 6. The through-hole 101 extends through the saddle plate 1, and the sliding rod 12 has an interference fit with the fixed cylinder 11.

[0016] The angle adjustment mechanism 6 includes a screw III 65; a vertical threaded hole is provided at the upper end of the saddle plate 1, and a screw III 65 threadedly connected to the threaded hole is provided in the threaded hole; a vertical slide groove 63 is provided on the side of the screw III 65; a slider 62 slidingly engaged with the slide groove 63 is provided in the slide groove, and the slider 62 is fixedly connected to the inner wall of the rotating ring 61; a groove communicating with the threaded hole is provided on the side of the saddle plate 1, and the rotating ring 61 is arranged in the groove, and the lower end of the rotating ring 61 is fixedly connected to a rotating drum 64, and the rotating drum 64 is connected to the saddle plate 1 through a bearing.

[0017] The two bubble levels 5 are perpendicular to each other, which facilitates auxiliary positioning.

[0018] Each of the fixing cylinder 11, the sliding rod 12, the screw rod II 13, and the support plate 14 is provided with two. The opposing surfaces of the two support plates 14 are provided with a plurality of spherical grooves, in which balls 16 are installed. This allows the support plates 14 to be clamped to the outer wall of the pipe via the balls 16 on their sides, thus adapting to different working environments.

[0019] The lower end of the saddle plate 1 is provided with a triangular groove.

[0020] The included angle of the triangular groove is 100-120°.

[0021] The working principle of the utility model is as follows: when using the device, the saddle plate 1 is placed on the pipe, and the two inclined surfaces of the triangular groove at the lower end of the saddle plate 1 are tangent to the outer circle of the pipe to achieve two-line contact. The vertical direction is determined by the plumb bob 4 to assist in adjusting the position of the saddle plate 1, and the slide bar 12 is pulled to make the support plate 14 located on both sides of the pipe. Then, the screw rod II 13 is adjusted to drive the support plate 14 to move up and down so that it is supported on the plane, thereby avoiding the saddle plate 1 being placed unstable when the pipe diameter is smaller than the length of the saddle plate 1, thereby affecting subsequent operations; at the same time, the support plate 14 is adjusted in height by the screw rod II 13, which is convenient for installation on planes of different heights on both sides of the pipe and adapts to more terrains; the support plate 14 can also be adjusted by adjusting the slide bar 12 to make the ball bearings 16 on its side rest against the outer wall of the pipe;

[0022] After placing the saddle plate 1, rotate the rotating ring 61, which drives the slider 62 to rotate. The slider 62 drives the screw rod III 65 to rotate through the slide groove 63, thereby moving the screw rod III 65 upward, so that the screw rod III 65 pushes up one side of the elevation plate 2, so that a certain angle is formed between the elevation plate 2 and the saddle plate 1;

[0023] The dual-axis electronic level 7 installed on the upper end of the elevation plate 2 can measure the absolute angle in two directions of the horizontal plane and is used as an auxiliary reference for the horizontal position through the bubble level 5;

[0024] After the point is determined, the guide punch 3 is struck to pass through the through hole 101 and contact the pipe, leaving a mark on the pipe.
