Description

Technical Field

[0002] During the installation of gas pipelines, a very important step is to accurately cut the pipes according to the actual installation requirements to obtain the pipe sections with the required size and shape specifications. This step not only affects the quality of subsequent processes, but also directly affects the performance and safety of the entire pipeline system. There are strict requirements for the quality of the cuts:

[0003] The pipe cut should be straight, that is, the cross section should be perpendicular to the pipe axis. This is the basis for ensuring the quality of the cut and is also a key factor in ensuring the quality and performance of the pipeline installation. If the cut is not straight, it will not only affect the quality of welding and threading, but also affect the straightness of the pipeline.

[0004] The inside and outside of the pipe mouth must be smooth and flat, without any burrs or iron slag. This is to prevent the pipe from being damaged due to rough cuts, and to avoid problems such as blockage and leakage during installation. At the same time, this can also extend the service life of the pipe and reduce damage caused by friction and corrosion.

DETAILED DESCRIPTION

[0038] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0039] During the pipeline installation process, pipe cutting is a crucial link. According to the actual needs of pipeline installation, the size and shape of the pipe must be accurately measured and determined to ensure that the cut pipe section can perfectly adapt to the installation environment. For the quality of the cut, we have put forward strict requirements: First, the pipe cut must be straight, which means that the cut must be absolutely perpendicular to the axis of the pipe. Once the cut is deviated, it will not only affect the subsequent welding and threading quality, but also cause the pipeline to be unable to maintain the proper straight state after the overall installation, thus burying safety hazards and affecting the service life and function of the pipeline. Secondly, the inside and outside of the pipe mouth must be smooth and free of burrs and iron slag. These sharp edges not only increase the resistance inside the pipeline, but may also cause fluid flow obstruction and reduce the working efficiency of the pipeline, and may also cause injuries to workers during operations such as welding. Therefore, the pipe mouth must be carefully polished and processed to ensure that its surface is smooth and free of burrs. In addition, the cut should not produce cross-sectional shrinkage. Cross-sectional shrinkage will invisibly reduce the effective cross-sectional area of ​​the pipe, making the fluid channel inside the pipe narrow. This will not only increase the flow resistance of the fluid and consume more energy, but may also cause uneven pressure distribution inside the pipeline, further threatening the structural integrity of the pipeline.

[0040] In the existing pipe cutting method, the pipe incision is rough and uneven, and secondary processing of the incision is often required, resulting in reduced work efficiency. The cutting positioning device provided in the present application can connect the pipe and the electric saw so that the electric saw cannot move left and right, thereby ensuring that the pipe incision is smooth, meeting the required requirements, avoiding secondary processing, and improving work efficiency.

[0041] The specific structure of the cutting positioning device provided in the present application is described in detail below in conjunction with the accompanying drawings.

[0042] Reference Figure 1-Figure 6 As shown, Figure 1 and Figure 2 A is a pipe, B is an electric saw, and the embodiment of the present application provides a cutting positioning device, including a connecting member 10, a binding assembly 20 and an adjusting assembly 30 connected to the connecting member 10, and a fixing assembly 40 disposed on the adjusting assembly 30;

[0043] like Figure 1 As shown, the connecting member 10 and the binding assembly 20 form an annular structure, the annular structure is sleeved with the pipeline, so that the cutting positioning device is fixed on the pipeline, and the fixing assembly 40 is connected to the housing of the electric saw, so that the electric saw is fixed on the cutting positioning device. At this time, the electric saw cannot move left and right, but can only rotate relative to the adjustment assembly 30 and the annular structure. The saw blade of the electric saw is in a vertical state, and the plane where the saw blade rotates is perpendicular to the axis of the pipeline, thereby ensuring that the cutting surface of the pipeline is neat;

[0044] The connecting member 10 includes a C-shaped plate 11, which may be an arc-shaped steel sheet with a certain width. A clamping block 12 is provided on the rear side of the outer wall of the C-shaped plate 11, which may be a metal square clamping block. A bayonet 13 is provided on the front outer wall of the bayonet 12, which may be a rectangular bayonet.

[0045] The binding assembly 20 includes a shell 21, a central axis 22, a tape spring 23, a steel belt 24, a lock 25 and a clamp 26. The shell 21 can be disc-shaped. The shell 21 is fixed to the front side of the outer wall of the C-shaped plate 11. The shell 21 is provided with an inner cavity, and the shell 21 is provided with an outlet. The central axis 22 is a column, and the central axis 22 is arranged in the middle of the inner cavity of the shell 21. The first end of the tape spring 23 is fixed to the outer wall of the central axis 22, and the second end of the tape spring 23 is wound around the outside of the central axis 22. The steel belt 24 can be made of soft steel and has a certain elasticity. The first end of the steel belt 24 is connected to the second end of the tape spring 23, and the steel belt The second end of 24 is wound around the outside of the tape spring 23 and passes through the shell 21 from the outlet. The snap ring 26 can be a rectangular ring body. The snap ring 26 is arranged at the second end of the steel belt 24. The snap ring 26 is engaged with the bayonet 13 of the clamping block 12, so that the steel belt 24 and the C-shaped plate 11 form an annular structure. The lock 25 is arranged on the shell 21. The lock 25 and the shell 21 clamp the steel belt 24. The structure and principle of the binding assembly 20 are the same as those of the existing tape measure, wherein the structure of the lock 25 and the principle of fixing the steel belt 24 are the same as the structure of the tape lock in the conventional tape measure and the principle of fixing the scale box, which is a known technology;

[0046] In the natural state, the tape measure spring 23 is in a stretched state, exerting an elastic force on the steel belt 24 to move toward the inside of the shell 21, and the retaining ring 26 is engaged with the outlet of the shell 21; when in use, the C-shaped plate 11 fits the front surface of the pipe, pulls the retaining ring 26, so that the steel belt 24 bypasses the rear surface of the pipe, and the retaining ring 26 is engaged with the retaining hole 13 of the clamping block 12. The steel belt 24 is tightened under the elastic force of the tape measure spring 23 and locked by the lock buckle 25, so that the annular structure formed by the steel belt 24 and the C-shaped plate 11 has a certain width and is tightly fitted on the pipe. Therefore, after the saw blade is fixed, the electric saw will not move left and right, thereby avoiding the saw blade from bouncing back and forth, resulting in a rough, curved and uneven cutting surface.

[0047] Reference Figure 4 As shown, in some embodiments, the adjustment assembly 30 includes a first steel tube 31 and a second steel tube 32. Both the first steel tube 31 and the second steel tube 32 can be square steel tubes, and two of each are provided opposite to each other.

[0048] Two first steel tubes 31 are arranged in parallel, and the first ends of the two first steel tubes 31 are connected to the outer wall of the C-shaped plate 11. The first steel tubes 31 are provided with a plurality of first connection holes 33, and the plurality of first connection holes 33 are evenly distributed along the extension direction of the first steel tubes 31;

[0049] Two second steel tubes 32 are arranged in parallel, and the two second steel tubes 32 are connected to the two first steel tubes 31 respectively. The second steel tube 32 is provided with a second connection hole 34 opposite to the first connection hole 33. The first connection hole 33 and the second connection hole 34 can both be a central through hole. Bolts penetrate the first connection hole 33 and the second connection hole 34, so that the first steel tube 31 and the second steel tube 32 can be detachably connected.

[0050] The fixing assembly 40 is arranged on the two second steel pipes 32. By bolting the first connecting hole 33 and the second connecting hole 34 at appropriate positions, the distance between the fixing assembly 40 and the annular structure can be adjusted, thereby adjusting the distance between the electric saw and the pipe, thereby stabilizing the pipe cutting pipeline.

[0051] Reference Figure 4 As shown, in some embodiments, the rear ends of the two first steel pipes 31 are rotatably connected to the outer wall of the C-shaped plate 11, and the front ends of the two first steel pipes 31 can swing up and down. Since the C-shaped plate 11 has a certain elasticity, when the C-shaped plate 11 is connected to pipes of different sizes, the distance between the front ends of the two first steel pipes 31 is not fixed. Therefore, the adjustment component 30 of the present application also includes a limiter, which is used to adjust the distance between the two first steel pipes 31 so that the two first steel pipes 31 are parallel;

[0052] The stopper is disposed between the two first steel tubes 31 , and includes an inner spiral tube 35 and a screw rod 36 , wherein the second side outer wall of the screw rod 36 is screwed to the first side inner wall of the inner spiral tube 35 ;

[0053] The second end of the inner spiral tube 35 is fixed on the first steel tube 31. A screw hole is provided on the other first steel tube 31. The inner spiral tube 35 is perpendicular to the first steel tube 31. The extending direction of the screw hole is perpendicular to the first steel tube 31.

[0054] When the screw 36 is rotated clockwise, the screw 36 moves outward relative to the inner screw tube 35. Conversely, when the screw 36 is rotated counterclockwise, the screw 36 moves inward relative to the inner screw tube 35, and the two first steel tubes 31 are swung so that the two first steel tubes 31 are relatively parallel. At this time, the screw 36 corresponds to the screw hole on the first steel tube 31. The screw 36 is rotated clockwise to be screwed into the screw hole, so that the two first steel tubes 31 are relatively parallel and fixed. At this time, the C-shaped plate 11 and the two first steel tubes 31 are in an upper and lower symmetrical state.

[0055] In some embodiments, a limiting ring 37 is disposed on the outer wall of the screw rod 36. The limiting ring 37 may be a metal ring. The side wall of the limiting ring 37 is engaged with the outer wall of the first steel tube 31 or the inner screw tube 35, thereby limiting the adjustable length of the screw rod 36.

[0056] The outer diameter of the limiting ring 37 matches the outer diameter of the inner spiral tube 35 .

[0057] In some embodiments, the outer wall of the limiting ring 37 is provided with anti-slip grooves to facilitate the rotation of the screw 36.

[0058] Reference Figure 5 and Figure 6 As shown, in some embodiments, the fixing assembly 40 includes a connecting plate 41, a rotating disk 42 and a fixing plate 43;

[0059] The connecting plate 41 may be a rectangular plate body, and the connecting plate 41 is disposed on the two second steel pipes 32. The rotating disk 42 is disposed on the side of the connecting plate 41 facing away from the second steel pipes 32. The rotating disk 42 is rotatably connected to the connecting plate 41 via a rotating shaft.

[0060] The fixing plate 43 is set on the rotating disk 42 by screws, and the fixing plate 43 is located on the side of the rotating disk 42 facing away from the connecting plate 41. The fixing plate 43 and the rotating disk 42 clamp the electric saw, so that the electric saw is fixed;

[0061] like Figure 5 As shown, the fixing plate 43 may be an arcuate plate body, which can fix the electric saw whose housing is a square, such as Figure 6 As shown, the fixing plate 43 may be a semicircular structure, which can fix the electric saw with a circular shell. The fixing plate 43 may also be other shapes. The shape of the fixing plate 43 matches the shell of the electric saw, so that the fixing plate 43 and the turntable 42 clamp the shell of the electric saw to fix the electric saw.

[0062] When the electric saw is fixed, the saw blade of the electric saw is in a vertical state, the plane where the electric saw blade is located is parallel to the plane where the turntable 42 is located, and perpendicular to the axis of the pipeline. At this time, the electric saw cannot move left and right. By holding the shell or handle of the electric saw, the electric saw, the fixed plate 43 and the turntable 42 are controlled to rotate, so that the electric saw can cut the pipeline.

[0063] In some embodiments, the fixing assembly 40 further includes an elastic anti-skid pad 44, which may be a rubber pad;

[0064] The elastic anti-skid pad 44 is fixed to the inner wall of the fixing plate 43 . The inner wall of the elastic anti-skid pad 44 matches the housing of the electric saw. The inner wall of the elastic anti-skid pad 44 fits the outer wall of the electric saw, thereby stably fixing the electric saw.

[0065] In some embodiments, since the spacing between the two second steel pipes 32 is changed by the size of the pipes, in order to facilitate the fixing of the fixing assembly 40 on the second steel pipes 32, slide grooves are provided on both sides of the connecting plate 41, and the length direction of the slide grooves is consistent with the width direction of the two second steel pipes 32. Screw holes are provided on the second steel pipes 32, and the screws pass through the slide grooves and are connected to the screw holes of the second steel pipes 32.

[0066] According to the above technical features, the working principle of the cutting positioning device provided by the present application in the actual application scenario is:

[0067] When using the cutting positioning device, the C-shaped plate 11 is attached to the front surface of the pipe, and the clamping ring 26 is pulled to make the steel belt 24 pass around the rear surface of the pipe, and the clamping ring 26 is clamped with the clamping port 13 of the clamping block 12. The steel belt 24 is tightened under the elastic force of the tape spring 23 and locked by the lock buckle 25, so that the connecting piece 10 and the binding assembly 20 are fixed on the pipe; the two first steel pipes 31 are swung to make them parallel, and fixed by the limiter, and the fixing assembly 40 is fixed to the two second steel pipes 32 by screws; the housing of the electric saw is clamped by the fixing plate 43 and the turntable 42, so that the electric saw is fixed on the cutting positioning device, and the saw blade of the electric saw is parallel to the turntable 42. When using, the housing or handle of the electric saw is held to control the rotation of the electric saw, the fixing plate 43 and the turntable 42, so that the pipe can be cut;

[0068] After use, the lock buckle 25 is opened, and the clamping ring 26 and the clamping block 12 are separated, so that the cutting and positioning device can be separated from the pipeline. When cutting the next pipeline of the same size, it is only necessary to fix the pipeline with the connecting piece 10 and the binding assembly 20 to start cutting.

[0069] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on the several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.
