Description

Technical Field

[0001] The invention relates to the technical field of impulse turbines, and in particular to a small-diameter water distribution ring pipe welding quality detection device. Background Art

[0002] The impulse turbine uses a special water guide mechanism to draw out a free jet with kinetic energy, which rushes towards the runner bucket to make the runner rotate and do work, thereby completing a hydraulic prime mover that converts water energy into mechanical energy. During the assembly process of the turbine, multiple pipes are welded to form a water distribution ring pipe. After welding, the welding quality must be tested. The traditional testing method is to apply a certain amount of pressure to the welding surface and then detect the pressure change through a pressure sensor. If the electrical signal sent by the pressure sensor is within a reasonable range, it means that the welding is in good condition. If the electrical signal sent by the pressure sensor changes greatly, it means that the welding quality is average and the overall operation is simple.

[0014] 1. First, when the water distribution ring pipe needs to be inspected, rotate the two rotating rings. During this process, the inspection plate is always against the welding surface, and the first pressure sensor is always sending out an electrical signal. Observe the size of the electrical signal sent by the first pressure sensor. If the size of the electrical signal is always within a reasonable range, it means that the welding quality of the welding surface is good.

[0015] 2. In addition, during the rotation of the rotating ring, the knocking cylinder moves up and down. Under the knocking action of the knocking cylinder, if the connection effect between the solidified solder on the welding surface and the pipeline is average, when the detection board is detected, different first pressure sensors will send different electrical signals, and the difference in the electrical signals is too large, thereby improving the detection effect;

[0016] 3. Then, in the process of the knocking rod moving up and down, when the knocking tube and the side wall of the welding surface are against each other, the second pressure sensor sends out an electrical signal. If the electrical signal sent by the second pressure sensor is too large, it means that the height of the side wall of the welding material is too high and needs to be processed in time. Then, when comparing the two second pressure sensors before and after, if there is a large difference in the electrical signals sent by the two second pressure sensors, it means that after knocking, the welding effect is general. If there is no large difference in the electrical signals sent by the two second pressure sensors, it means that the welding condition is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 3 The side wall of the first connecting rod 10 is evenly provided with a plurality of mounting grooves 11 in the circumferential direction, and the side wall of the fixed frame 1 is slidably connected with a control rod 14, and one end of the control rod 14 is fixedly connected with a mounting plate 12 in the fixed frame 1, and a first spring 13 is fixedly connected between the mounting plate 12 and the fixed frame 1, and two mounting rods 15 are fixedly connected to the side wall of the mounting plate 12, and one end of the two mounting rods 15 extends to the mounting groove 11 and is slidably connected to the mounting groove 11, and the lower side edges of the detection plate 29 are all smooth arc settings, and when the detection plate 29 and the welding surface are against each other, the lower surface of the detection plate 29 is also smooth, so the detection plate 29 will only form an extrusion detection effect on the welding surface, and will not cause other effects on the welding surface;

[0031] like Figure 8 Two slide grooves 35 are symmetrically formed in the connecting tube 17, and a slide plate 33 is slidably connected in the two slide grooves 35. A third spring 34 is fixedly connected between the slide plate 33 and the slide groove 35. The two slide plates 33 are fixedly connected to the threaded ring 24. First, the connection between the slide plate 33, the third spring 34 and the slide groove 35 is as follows: Figure 8 As shown, the third springs 34 on both sides are in a balanced state, so the threaded ring 24 and the connecting cylinder 17 are in a relatively balanced state;

[0032] The adjustment assembly includes a fifth connecting rod 37 fixedly mounted on the side wall of each group of rotating cylinders 5, a sleeve 26 is slidably connected to the outer side of the fifth connecting rod 37, a fourth spring 36 is fixedly connected between the sleeve 26 and the fifth connecting rod 37, a first connecting plate 16 is fixedly connected to the outer side of the sleeve 26, the side walls of the two first connecting plates 16 are respectively fixedly connected to the connecting cylinders 17 through the fourth connecting rod 32, the inner walls of the two connecting cylinders 17 are rotatably connected to the threaded ring 24 together, and the threaded rod 23 is threadedly penetrated through the threaded ring 24;

[0033] First, the first pressure sensor 28 is a device or apparatus that can sense pressure signals and convert pressure signals into usable output electrical signals according to certain rules. When it is necessary to perform detection operations on the pipeline welding surface, the rotating ring 2 is sleeved on the outside of the pipeline, and the rotating ring 2 is moved to the outside of the welding surface, and the control rod 14 is moved. The control rod 14 drives the mounting plate 12 to move, and the mounting plate 12 compresses the first spring 13 while driving the mounting rod 15 to move until the mounting rod 15 is moved out of the mounting groove 11, and then the ninth connecting rod 9, the fixed plate 8 and the connecting frame 3 are rotated around the first connecting rod 10, and the connecting frame 3 drives the rotating ring 2 and the fixed ring 7 to rotate until the two rotating rings 2 are in a vertical state with the pipeline, and then the control rod 14 is released. Under the action of the first spring 13, the mounting plate 12 drives the mounting rod 15 to move, and the mounting rod 15 enters the mounting groove 11. Since the water distribution ring pipe is curved, it is necessary to complete the fixing frame 1 and the connecting rod. The position and angle of the connecting frame 3 are adjusted so that during the inspection, the two rotating rings 2 are both in a vertical state with the water distribution ring pipe at the inspection position. Then, the threaded ring 24 is held and the threaded rod 23 is rotated so that the threaded rod 23 moves relative to the threaded ring 24 in the direction close to the welding surface. The threaded rod 23 drives the third connecting plate 20 and the round rod 30 to move downward until the round rod 30 is located on both sides of the welding surface, and the inspection plate 29 is against the welding surface, and the first pressure sensor 28 sends an electrical signal. At this time, the inspection plate 29 forms an extrusion effect on the welding surface. Then, the two rotating rings 2 are rotated at the same time. During this process, the inspection plate 29 is always against the welding surface, and the first pressure sensor 28 is always sending an electrical signal. The size of the electrical signal sent by the first pressure sensor 28 is observed. If the size of the electrical signal is always within a reasonable range, it means that the welding quality of the welding surface is good. If the size of the electrical signal is too large or too small, it means that the welding quality is average, thereby completing the inspection operation on the welding surface.

[0034] During the above working process, there will be an angle between the two rotating rings 2, but under the action of the sleeve 26, the fifth connecting rod 37, the fourth spring 36, the first connecting plate 16, and the fourth connecting rod 32, the two fourth springs 36 are in a balanced state, and the connecting tube 17 and the threaded rod 23 as a whole are always at the midpoint of the two rotating rings 2. Therefore, the detection plate 29 is always on the outside of the welding surface and against the welding surface, the operation is simple, and the detection effect is good.

[0035] like Figure 4 , Fig.10 , Fig.11A knocking assembly is installed on the lower side of the third connecting plate 20, and the knocking assembly includes a positioning ring 39 slidably sleeved on the outer side of the round rod 30, and the side wall of the positioning ring 39 is fixedly connected to two seventh connecting rods 40, and the side walls of the two seventh connecting rods 40 are fixedly connected to the knocking rings 41, and the knocking rods 42 are slidably connected in the two knocking rings 41, and the upper side of the knocking rod 42 is fixedly connected to the second pressure sensor 43, and the upper side of the second pressure sensor 43 is fixedly connected to the fourth connecting plate 47, and a fifth spring 44 is fixedly connected between the fourth connecting plate 47 and the knocking ring 41, and the side wall of the knocking rod 42 is fixedly connected to the eighth connecting rod 45, and the outer side of the eighth connecting rod 45 is rotatably connected to the knocking tube 46, and the outer side of the positioning ring 39 is fixedly connected to the sixth Connecting rod 38, the outer side of the sixth connecting rod 38 is fixedly connected with a moving ring 25, the second connecting rod 19 is slidably connected in the moving ring 25, the outer side of the second connecting rod 19 is fixedly connected with a third connecting rod 48, the side wall of the third connecting rod 48 is provided with an oblique groove 21, the sliding rod 22 is slidably connected in the oblique groove 21, the sliding rod 22 is fixedly connected to the first connecting plate 16, the first connecting plate 16 is fixedly connected with a second spring 27, the second spring 27 and the third connecting rod 48 are against each other, the side wall of the rotating ring 2 is rotatably connected with a fixing ring 7, the side wall of the fixing ring 7 is fixedly connected with a square ring 6, the fixing ring 7 and the connecting frame 3 are fixedly connected, the lower side of the round rod 30 is set in an arc shape, and the outer surfaces of this round rod 30 and the knocking tube 46 are both smooth;

[0036] First, when the rotating ring 2 rotates, the fixed ring 7 and the connecting frame 3 are fixedly connected and in a fixed state. Then, after the rotating ring 2 is adjusted, the second connecting rod 19 is always located on the surface of the square ring 6 and abuts against the square ring 6. Therefore, during the rotation of the rotating ring 2, the second connecting rod 19 is always abutted against the square ring 6. Fig.10Based on the direction, from the vertical direction, the second connecting rod 19 and the third connecting rod 48 always move up and down relative to the first connecting plate 16. Due to the limiting effect of the inclined groove 21 and the sliding rod 22, and under the limiting effect of the second spring 27, from the overall point of view, the second connecting rod 19 and the third connecting rod 48 always move along the direction of the inclined groove 21 and the sliding rod 22. Since the second connecting rod 19 and the moving ring 25 are connected for left and right sliding, the second connecting rod 19 will drive the moving ring 25 and the sixth connecting rod 38 to move up and down, and the sixth connecting rod 38 drives the seventh connecting rod 4 through the positioning ring 39. 0 and the knocking ring 41 move up and down, the knocking ring 41 drives the knocking rod 42 to move up and down through the second pressure sensor 43 and the fifth spring 44, the knocking rod 42 drives the knocking cylinder 46 to move up and down, the knocking cylinder 46 is located at both ends of the welding surface, and the knocking cylinder 46 moving up and down will form a knocking effect on the connection between the welding surface and the pipeline. Under the knocking action of the knocking cylinder 46, if the connection effect between the solidified welding material on the welding surface and the pipeline is general, when the detection plate 29 performs detection, different first pressure sensors 28 will send different electrical signals, and the difference in the electrical signals is too large, thereby improving the detection effect;

[0037] In the above working process, the second pressure sensor 43 is a device or apparatus that can sense the pressure signal and convert the pressure signal into an available output electrical signal according to a certain rule. When the knocking rod 42 moves up and down, when the knocking tube 46 and the side wall of the welding surface are against each other, the second pressure sensor 43 will send out a corresponding electrical signal. Figure 6 Based on the direction, first compare the size of the electrical signal emitted by the second pressure sensor 43 after the knocking tube 46 and the welding surface are against each other during each knocking process. If the electrical signal emitted by the second pressure sensor 43 is too large, it means that the height of the welding material is too high and needs to be processed in time. Then, compare the two second pressure sensors 43 before and after. If there is a large difference in the electrical signals emitted by the two second pressure sensors 43, it means that after knocking, the welding effect is general. If there is no large difference in the electrical signals emitted by the two second pressure sensors 43, it means that the welding condition is good.

[0038] In the present invention, when it is necessary to perform a detection operation on the pipeline welding surface, the rotating ring 2 is sleeved on the outside of the pipeline, and the rotating ring 2 is moved to the outside of the welding surface, and the control rod 14 is moved. The control rod 14 drives the mounting plate 12 to move, and the mounting plate 12 compresses the first spring 13 and drives the mounting rod 15 to move until the mounting rod 15 moves out of the mounting groove 11, and then the ninth connecting rod 9, the fixed plate 8 and the connecting frame 3 are rotated around the first connecting rod 10, and the connecting frame 3 drives the rotating ring 2 and the fixed ring 7 to rotate until the two rotating rings 2 are in a vertical state with the pipeline, and then the control rod 14 is released. Under the action of the first spring 13, the mounting plate 12 drives the mounting rod 15 to move, and the mounting rod 15 enters the mounting groove 11. Since the water distribution ring pipe is curved, it is necessary to complete the adjustment operation of the position and angle of the fixing frame 1 and the connecting frame 3 so that the two rotating rings 2 are in a vertical state with the pipeline. The rings 2 are in a vertical state with the water distribution ring pipe at the detection position, and then hold the threaded ring 24, rotate the threaded rod 23, and move the threaded rod 23 relative to the threaded ring 24 toward the direction close to the welding surface, and the threaded rod 23 drives the third connecting plate 20 and the round rod 30 to move downward until the round rod 30 is located on both sides of the welding surface, and the detection plate 29 and the welding surface are against each other, and the first pressure sensor 28 sends an electrical signal. At this time, the detection plate 29 forms an extrusion effect on the welding surface, and then the two rotating rings 2 are rotated at the same time. During this process, the detection plate 29 is always against the welding surface, and the first pressure sensor 28 is always sending an electrical signal. Observe the size of the electrical signal sent by the first pressure sensor 28. If the size of the electrical signal is always within a reasonable range, it means that the welding quality of the welding surface is good. If the size of the electrical signal is too large or too small, it means that the welding quality is average, and then complete the detection operation on the welding surface;

[0039] In the above working process, there is an angle between the two rotating rings 2, but under the action of the sleeve 26, the fifth connecting rod 37, the fourth spring 36, the first connecting plate 16, and the fourth connecting rod 32, the two fourth springs 36 are in a balanced state, and the connecting tube 17 and the threaded rod 23 are always at the midpoint of the two rotating rings 2 as a whole, so the detection plate 29 is always outside the welding surface and against the welding surface, the operation is simple, and the detection effect is good;

[0040] When the rotating ring 2 rotates, the fixed ring 7 and the connecting frame 3 are fixedly connected and in a fixed state. Then, after the rotating ring 2 is adjusted, the second connecting rod 19 is always located on the surface of the square ring 6 and abuts against the square ring 6. Therefore, during the rotation of the rotating ring 2, the second connecting rod 19 is always abutted against the square ring 6. Fig.10Based on the direction, from the vertical direction, the second connecting rod 19 and the third connecting rod 48 always move up and down relative to the first connecting plate 16. Due to the limiting effect of the inclined groove 21 and the sliding rod 22, and under the limiting effect of the second spring 27, from the overall point of view, the second connecting rod 19 and the third connecting rod 48 always move along the direction of the inclined groove 21 and the sliding rod 22. Since the second connecting rod 19 and the moving ring 25 are connected for left and right sliding, the second connecting rod 19 will drive the moving ring 25 and the sixth connecting rod 38 to move up and down, and the sixth connecting rod 38 drives the seventh connecting rod 4 through the positioning ring 39. 0 and the knocking ring 41 move up and down, the knocking ring 41 drives the knocking rod 42 to move up and down through the second pressure sensor 43 and the fifth spring 44, the knocking rod 42 drives the knocking cylinder 46 to move up and down, the knocking cylinder 46 is located at both ends of the welding surface, and the knocking cylinder 46 moving up and down will form a knocking effect on the connection between the welding surface and the pipeline. Under the knocking action of the knocking cylinder 46, if the connection effect between the solidified welding material on the welding surface and the pipeline is general, when the detection plate 29 performs detection, different first pressure sensors 28 will send different electrical signals, and the difference in the electrical signals is too large, thereby improving the detection effect;

[0041] In the above working process, the second pressure sensor 43 is a device or apparatus that can sense the pressure signal and convert the pressure signal into an available output electrical signal according to a certain rule. When the knocking rod 42 moves up and down, when the knocking tube 46 and the side wall of the welding surface are against each other, the second pressure sensor 43 will send out a corresponding electrical signal. Figure 6 Based on the direction, first compare the size of the electrical signal emitted by the second pressure sensor 43 after the knocking tube 46 and the welding surface are against each other during each knocking process. If the electrical signal emitted by the second pressure sensor 43 is too large, it means that the height of the welding material is too high and needs to be processed in time. Then, compare the two second pressure sensors 43 before and after. If there is a large difference in the electrical signals emitted by the two second pressure sensors 43, it means that after knocking, the welding effect is general. If there is no large difference in the electrical signals emitted by the two second pressure sensors 43, it means that the welding condition is good.
