Description

Technical Field

[0001] The utility model relates to the technical field of high alloy pipeline processing, in particular to an adjusting mechanism for facilitating efficient welding of high alloy pipelines. Background Art

[0002] Alloy pipe is a kind of seamless steel pipe, and its performance is much higher than that of ordinary seamless steel pipe, because this kind of steel pipe contains more Cr, and its high temperature resistance, low temperature resistance and corrosion resistance are unmatched by ordinary seamless steel pipe, so alloy pipe is widely used in petroleum, aerospace, chemical industry, electric power, boiler, military industry and other industries;

[0003] However, during the welding process of alloy pipes, the alloy pipes need to be limited, and welding is performed by pressing two groups of alloy pipes against each other. However, due to the fixed welding structure of conventional welding equipment, only a single group of pipes can be limited at a time, resulting in low pipe welding clamping efficiency. In addition, due to the inconsistent sorting lengths of some pipes, the pipes are very likely to fall out of the operating frame and cause the pipe ends to warp, thereby affecting the welding efficiency between the two groups of opposing pipes.

[0004] In view of the technical defects in this aspect, a solution is now proposed. Utility Model Content

[0005] The purpose of this utility model is not only to limit the clamping of multiple groups of opposing pipes, but also to adapt to the welding of pipes of various lengths, while maintaining the balance state when clamping the pipes, reducing pipe deviation or end warping, and improving pipe welding efficiency.

[0006] The purpose of the utility model can be achieved through the following technical solutions: an adjustment mechanism that is convenient for efficient welding of high-alloy pipes, comprising a bottom frame and two groups of vertical plates, the two groups of vertical plates are respectively slidably arranged inside the bottom frame at both sides, and the front and rear end surfaces of the bottom frame are each provided with a slide groove 1, and the front and rear end surfaces of the vertical plates are fixedly installed with sliders at the bottom end positions, the sliders at the front and rear end of each group of vertical plates are respectively slidably connected to the corresponding slide groove 1, a number of groups of card grooves 1 are equidistantly arranged at the middle and upper ends of the vertical plates, card frames are fixedly installed at the front and rear positions of the middle sections of the opposite surfaces of the two groups of vertical plates, a movable plate is slidably connected between the two groups of card frames on the same side, and a number of groups of card grooves 2 are equidistantly arranged at the middle and upper ends of the movable plate, the top inner wall of the card groove 2 is a curved structure, and the card groove 1 corresponds to the card groove 2 on the left and right.

[0007] Furthermore, the vertical length of the movable plate is three-quarters of the vertical length of the upright plate, and plug rods are fixedly installed at the front and rear ends opposite the movable plate, and plug tubes are fixedly installed at the upper and lower corresponding positions of the bottom inner wall of the bottom frame and the plug rods, and the plug rods are inserted into the corresponding plug tubes.

[0008] Furthermore, a spring damping shock absorber is commonly provided between the insertion rod and the inner wall of the bottom of the insertion tube, and a round shaft is fixedly installed on the front and rear end surfaces of each group of movable plates at the lower end of the card frame, and a sliding frame is commonly sleeved between the two groups of round shafts in the same row.

[0009] Furthermore, a connecting plate is fixedly installed at the center between the front and rear sets of sliding frames, and a push rod is provided at the center of the bottom of the connecting plate. The bottom of the push rod extends to the inner wall of the bottom of the bottom frame and is provided with a cylinder.

[0010] Furthermore, a concave abutment frame is movably provided on the side of the two groups of vertical plates away from each other and located at the upper end of the card frame, and transverse grooves are provided at the front and rear ends of the concave abutment frame.

[0011] Furthermore, a second circular shaft is fixedly installed on the front and rear end surfaces of the vertical plate at a height corresponding to the transverse groove, and the second circular shaft is slidably connected to the inside of the corresponding transverse groove. A second spring damping shock absorber is jointly provided between the second circular shaft and the inner wall of one side of the corresponding transverse groove.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model provides vertical plates, movable plates, sliding frames, connecting plates and cylinders, and inserts several sets of alloy pipes into the vertical plates and movable plates on both sides, and the alloy pipes sequentially pass through the interior of the first and second card slots. Then, the driving connecting rods and two sets of sliding frames are used to sink downward, and the sliding frames respectively pull the corresponding movable plates downward until the inner wall of the top of the second card slot presses against the surface of the pipe. Therefore, several sets of pipes are clamped by the vertical plates and the movable plates, and the two opposite sets of connecting rods on the left and right are offset to reduce the deviation of the pipes during the subsequent welding process.

[0014] 2. The utility model provides a concave abutment frame. During the alloy pipe clamping process, one end of the pipe extends outside the vertical plate. The inner walls of one side of the left and right groups of concave abutment frames elastically press the outer end of the pipe body, thereby forcing several groups of pipes to be aligned and keep the welding ends of several groups of pipes in the same plane. At the same time, it helps to maintain the balance of the pipe and reduce the warping of the pipe, thereby improving the welding efficiency of the pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] Example 1:

[0023] See also Figure 1 - Figure 4 As shown, an adjustment mechanism for efficient welding of high-alloy pipes comprises a bottom frame 1 and two groups of vertical plates 2, the two groups of vertical plates 2 are respectively slidably arranged inside the bottom frame 1 at both sides, and the front and rear end surfaces of the bottom frame 1 are provided with a slide groove 3, and the front and rear end surfaces of the vertical plates 2 are fixedly installed with sliders 4 at the bottom end, and the sliders 4 at the front and rear end of each group of vertical plates 2 are respectively slidably connected to the corresponding slide groove 3, which is characterized in that: a number of groups of card grooves 5 are equidistantly arranged at the middle and upper ends of the vertical plates 2, card frames 6 are fixedly installed at the front and rear positions of the middle sections of the opposite surfaces of the two groups of vertical plates 2, a movable plate 7 is slidably connected between the two groups of card frames 6 on the same side, and a number of groups of card grooves 2 8 are equidistantly arranged at the middle and upper ends of the movable plate 7, the top inner wall of the card groove 2 8 is a curved structure, and the card groove 1 5 corresponds to the card slot 2 8 or so, the vertical length of the movable plate 7 is three-quarters of the vertical length of the vertical plate 2, and the opposite sides of the movable plate 7 are fixedly installed with plug rods 9 at the front and rear ends, and the inner wall of the bottom of the bottom frame 1 and the plug rods 9 are fixedly installed with plug tubes 10 at the corresponding upper and lower positions, and the plug rods 9 are inserted into the corresponding plug tubes 10, and a spring damping shock absorber 11 is commonly provided between the plug rods 9 and the inner wall of the bottom of the plug tube 10. The front and rear ends of each group of movable plates 7 are fixedly installed with a round shaft 12 at the lower end of the card frame 6, and a sliding frame 13 is commonly sleeved between the two groups of round shafts 12 in the same row. A connecting plate 14 is fixedly installed at the center between the front and rear groups of sliding frames 13, and a push rod 15 is provided at the center of the bottom of the connecting plate 14. The bottom of the push rod 15 extends to the inner wall of the bottom of the bottom frame 1 and is provided with a cylinder 16;

[0024] First, several sets of alloy pipes are passed through the interior of the left and right sets of vertical plates 2, and the middle sections of the pipes are clamped into the interior of the card slot 5. The ends of the two sets of pipes on the left and right sides are abutted against each other, and the abutted ends are the welding ends. Then, the cylinder 16 is started, and the push rod 15 is used to pull the connecting plate 14 and the two sets of sliding frames 13 downward. As a result, the internal part of the sliding frame 13 pulls the circular shaft 12 and the movable plate 7 downward until the top inner wall of the movable plate 7 abuts against the surface of the pipe body. At the same time, the insertion rod 9 is inserted into the insertion tube 10, causing the spring damping shock absorber 11 to be compressed. As a result, the single set of alloy pipes is clamped together by the vertical plate 2 and the movable plate 7, thereby maintaining the stable clamping of multiple sets of high-alloy pipes and reducing their deviation during the subsequent welding process.

[0025] It is worth noting that, since the lengths of the two groups of oppositely welded pipes are different during the welding process, it is necessary to slide the vertical plate 2, and the slider 4 slides inside the slide groove 3, thereby adjusting the distance between the two adjacent groups of vertical plates 2, ensuring that the center of each group of pipes passes through the interior of the vertical plate 2, and facilitating the clamping and welding of high-alloy pipes of different specifications and lengths, thereby improving the efficiency of pipe processing;

[0026] When the welding of two adjacent groups of pipes is completed, the cylinder 16 is started again, and the cylinder 16 uses 15 to push the connecting plate 14 and the sliding frame 13 to lift upward. On the contrary, the inner wall of the sliding frame 13 pushes the circular shaft 12 and the movable frame 7 upward synchronously, and the card slot 2 8 moves upward relative to the pipe. The inner wall of the top of the card slot 2 8 loses the pressure on the pipe surface, making it easier to fall off and remove the welded pipe.

[0027] Example 2:

[0028] See also Figure 3 - Figure 4 As shown, a concave abutment frame 17 is movably provided on the side of the two sets of vertical plates 2 away from each other and located at the upper end of the card frame 6. A transverse groove 18 is provided on the front and rear ends of the concave abutment frame 17. A second circular shaft 19 is fixedly installed on the front and rear end surfaces of the vertical plates 2 at a height corresponding to the transverse groove 18, and the second circular shaft 19 is slidably connected to the corresponding transverse groove 18. A second spring damping shock absorber 20 is commonly provided between the second circular shaft 19 and the inner wall of one side of the corresponding transverse groove 18.

[0029] During the alloy pipe clamping process, one end of the pipe extends to the outside of the vertical plate 2, and the inner walls of one side of the two groups of concave abutment frames 17 on the left and right sides elastically press the outer end of the pipe body, thereby forcing several groups of pipes to be aligned and keep the welding ends of several groups of pipes in the same plane, while assisting in maintaining the balance of the pipes, reducing the warping of the pipes, and thus improving the welding efficiency of the pipes; and the stop position of the concave abutment frame 17 changes according to the length of the pipe extending outside the vertical plate 2. The longer the length of the pipe extending outside the vertical plate 2, the more the inner wall of the concave abutment frame 17 is abutted, and the circular shaft 19 and the inside of the transverse groove 18 move relative to each other, and the spring damping shock absorber 20 is compressed. On the contrary, the concave abutment frame 17 moves in the opposite direction.

[0030] Working principle:

[0031] When the present invention is used, firstly, a plurality of sets of alloy pipes are inserted into the interior of the left and right sets of vertical plates 2 in opposition, and the middle sections of the pipes are clamped into the interior of the clamping slot 15, the ends of the two sets of pipes opposing each other, and the ends that are braced against each other are welded ends, and then the cylinder 16 is started, which uses the push rod 15 to pull the connecting plate 14 and the two sets of sliding frames 13 downward, thereby pulling the circular shaft 12 and the movable plate 7 downward inside the sliding frame 13 until the top inner wall of the movable plate 7 abuts against the surface of the pipe body, and at the same time, the insertion rod 9 is inserted into the insertion tube 10, causing the spring damping shock absorber 11 to be compressed, thereby, a single set of alloy pipes is clamped by the vertical plate 2 and the movable plate 7;

[0032] At the same time, one end of the pipe extends to the outside of the vertical plate 2, and the inner walls of one side of the left and right sets of concave abutment frames 17 elastically press the outer end of the pipe body, thereby forcing the several sets of pipes to be aligned and keep the welding ends of the several sets of pipes in the same plane, while helping to maintain the balance of the pipes, and then the connection ends of the several sets of pipes are welded;

[0033] When the welding of two adjacent groups of pipes is completed, the cylinder 16 is started again, and the cylinder 16 uses 15 to push the connecting plate 14 and the sliding frame 13 to lift upward. On the contrary, the inner wall of the sliding frame 13 pushes the circular shaft 12 and the movable frame 7 upward synchronously, and the card slot 2 8 moves upward relative to the pipe. The inner wall of the top of the card slot 2 8 loses the pressure on the pipe surface, making it easier to fall off and remove the welded pipe.
