Description

Technical Field

[0001] The invention relates to the technical field of detection devices, and in particular to a composite pipe ceramic lining detection device. Background Art

[0002] The composite pipe ceramic lining detection device is mainly used to detect the quality and integrity of the ceramic lining in the composite pipe. The device is usually composed of an ultrasonic probe, a signal processing unit, a display and a mechanical scanning system. The ultrasonic probe emits high-frequency sound waves, penetrates the ceramic lining and receives the reflected signal. By analyzing the time delay and intensity change of the signal, it is determined whether the lining has defects such as cracks, pores or uneven thickness. The signal processing unit filters, amplifies and digitizes the received data to ensure the detection accuracy. The display shows the detection results in real time, which is convenient for the operator to make intuitive judgments. The mechanical scanning system ensures that the probe can move evenly along the inner wall of the pipeline to achieve comprehensive detection. The device has the characteristics of high sensitivity, non-destructiveness and high degree of automation. It is widely used in industries such as petroleum, chemical and electric power to ensure the safety and service life of composite pipes.

[0003] However, in the prior art, when inspecting the ceramic lining of a three-way composite pipe, it is necessary to manually adjust the position of the pipe repeatedly for inspection, thereby reducing the overall inspection efficiency.

[0023] Furthermore, the limiting assembly 40 includes a push rod 2 409 fixedly connected to the front end of the push rod 1 43, a rack 2 400 is fixedly connected to the middle of the left side of the outer surface of the push rod 2 409, a rotating column 401 is fixedly connected to the left side of the middle of the upper end of the bottom plate 2, the rotating column 401 is located at the left rear of the push rod 2 409, a pulley 2 402 is fixedly connected to the middle of the outer surface of the rotating column 401, a circular groove 403 is opened in the middle of the upper end of the rotating column 401, an arc groove 404 is opened on the front side of the middle of the upper end of the circular groove 403, the arc groove 404 is connected to the circular groove 403, the bottom wall of the circular groove 403 is rotatably connected to the mounting column 1 405, and the inner surfaces of the arc groove 404 are mutually connected. An arc hole 4022 is commonly opened at the far end, and a push plate 406 is fixedly connected to the lower left part of the outer surface of the mounting column 405, and the push plate 406 is slidably connected to the inner surface of the arc groove 404. An arc tube 407 is fixedly connected to the middle part of the front end of the push plate 406, and the outer surface of the arc tube 407 is slidably connected to the inner surface of the arc hole 4022. The end where the push plate 406 and the inner surface of the arc groove 404 are close to each other is commonly fixedly connected with a spring 408, and the spring 408 is located on the outside of the arc tube 407. A right-angle gear 4099 is fixedly connected to the right side of the upper outer surface of the mounting column 405, and the right-angle gear 4099 is meshed with the rack 2 400.

[0024] Furthermore, a spiral rod 411 is rotatably connected to the front end of the rack 2 400, a fixed plate 2 412 is fixedly connected to the left middle part of the upper end of the base plate 2, the fixed plate 2 412 is located in the front part directly below the spiral rod 411, a spiral hole block 413 is fixedly connected to the upper end of the fixed plate 2 412, the inner surface texture of the spiral hole block 413 cooperates with the outer surface texture of the spiral rod 411, a mounting column 2 414 is fixedly connected to the right middle part of the base plate 2, a pulley 3 415 is rotatably connected to the middle part of the outer surface of the mounting column 2 414, a mounting column 3 416 is rotatably connected to the middle part of the upper end of the base plate 2, a pulley 4 417 is fixedly connected to the middle part of the outer surface of the mounting column 3 416, a one-way shaft 418 is fixedly connected to the upper part of the outer surface of the mounting column 3 416, a C-shaped plate 419 is fixedly connected to the front side of the middle part of the upper end of the base plate 2, an inclined plate 410 is fixedly connected to the right side of the outer surface of the C-shaped plate 419, and a laser detector 499 is fixedly connected to the front end of the spiral rod 411 through a disc.

[0025] Furthermore, an operating disk 421 is rotatably connected to the upper end of the C-shaped plate 419 . Four cross slots 422 are arranged in a matrix on the upper end of the operating disk 421 . The lower end of the operating disk 421 is fixedly connected to the upper end of the one-way shaft 418 .

[0026] Furthermore, pulley four 417 is connected to the outer surfaces of pulley three 415 and pulley two 402 through belt transmission.

[0027] First, by starting the hydraulic cylinder 42, the output end of the hydraulic cylinder 42 drives the push rod 1 43 fixedly connected thereto to move forward through the piston rod, and the fixed plate 1 45 slidably connected to the lower part of the outer surface of the push rod 1 43 plays a limiting support effect on the push rod 1 43, and when the push rod 1 43 moves forward, it can simultaneously drive the push rod 2 409 fixedly connected thereto forward, and because the rear end of the spiral rod 411 is rotatably connected to the front end of the push rod 2 409, and the outer surface of the spiral rod 411 and the inner surface texture of the spiral hole block 413 cooperate with each other, when the spiral rod 411 is moved forward by the push rod 2 409, the spiral rod 411 can rotate at the front end of the push rod 2 409, and it can be known from the above that the front end of the spiral rod 411 is fixedly connected with the laser detector 499 through the disc, so the laser detector 499 can rotate simultaneously with the spiral rod 411, and move forward to the inside of the vertical part of the composite pipe wall while rotating to detect the lining, thereby improving the detection efficiency and avoiding the situation where the lining is missed; After the vertical part of the pipe wall lining is inspected, it is necessary to start the hydraulic cylinder 42 to move its output end backwards. When the output end of the hydraulic cylinder 42 moves backwards, its output end can drive the push rod 1 43 to move backwards through the piston rod. When the push rod 1 43 moves backwards, it can also drive the push rod 2 409 to move backwards until the rack 2 400 fixedly connected to the left side of the outer surface of the push rod 2 409 contacts the laser detector 499. This is the second processing process. When rack 2 400 moves backward and contacts right-angle gear 4099 and meshes with it, it can drive right-angle gear 4099 to rotate, and right-angle gear 4099 drives push plate 406 to slide in arc groove 404 at the same time, so that push plate 406 pushes arc tube 407 to slide to the inner cavity of arc hole 4022, and squeezes spring 408 at the same time. When spring 408 is compressed to the maximum limit, push plate 406 can drive rotating column 401 to rotate at the same time under the rotation of mounting column 1 405, and then rotating column 401 drives pulley 2 402 fixedly connected to its outer surface to rotate. As can be seen from the above, pulley 4 417 is connected to the outer surface of pulley 3 415 and pulley 2 402 through belt transmission. Therefore, when pulley 2 402 rotates, it can drive pulley 3 415 and pulley 4 417 to rotate at the same time. When the pulley 417 rotates, it can drive the mounting column 3 416 fixed thereto to rotate, and then the mounting column 3 416 drives the one-way shaft 418 to rotate, and the outer teeth of the right-angle gear 4099 are set at 90 degrees, and the stroke of the rack 2 400 just cooperates with the right-angle gear 4099, and under the action of the one-way shaft 418, the operating disk 421 can only rotate 90 degrees, and when the teeth on the outer surface of the right-angle gear 4099 disengage from the rack 2 400, the push plate 406 will be restored to its initial state under the action of the spring 408, and the mounting column 1 405 drives the right-angle gear 4099 to restore to its initial state along with the push plate 406, and in this process, the rotating column 401 will not be prompted to rotate; After the operating disk 421 drives the composite pipe at its upper end to rotate ninety degrees, the hydraulic cylinder 42 is started again to move the right-angle gear 4099 forward to detect the inner wall of the horizontal end of the composite pipe. Since the right-angle gear 4099 is in the shape of a right-angle gear, the rack 2 400 does not mesh with the right-angle gear 4099 when it moves forward, so the operating disk 421 does not rotate, thereby achieving the purpose of detecting the inner wall of the three-way composite pipe, avoiding the need for manual repeated adjustment of the pipeline position, thereby improving the subsequent detection efficiency.

[0028] The laser detector 499 mentioned above is a conventional setting in the prior art. In this solution, it only needs to detect the pipeline lining. Its specific working principle and installation method are conventional designs in the prior art, so this solution will not elaborate on it in detail.

[0029] The one-way shaft 418 mentioned above is a conventional setting in the prior art, and its specific working principle is as follows: Forward transmission: When the one-way shaft 418 rotates in the set forward direction, the inner ring rotates in the same direction. The special structure on the inner ring, such as the groove or the inclined surface, will push the roller or the wedge to move away from the axis. The roller or the wedge will be tightly wedged between the inner ring and the outer ring, so that the inner ring, the roller or the wedge and the outer ring become a whole. In this way, the rotation of the one-way shaft 418 can be smoothly transmitted to the outer ring, driving other parts connected to it to operate together, and realizing power output; Reverse separation: When the one-way shaft 418 rotates in the reverse direction or the outer ring speed is higher than the forward speed of the one-way shaft 418, the roller or wedge is no longer wedged between the inner ring and the outer ring. The roller or wedge is disengaged from the outer ring under the action of the spring, and the connection between the inner ring and the outer ring is lost. At this time, the reverse rotation of the one-way shaft 418 will not be transmitted to the outer ring, or the movement of the outer ring will not affect the one-way shaft 418. The two can achieve relative free rotation, avoiding the influence of the reverse force on the one-way shaft 418 and its connected parts.

[0030] Therefore, the one-way shaft 418 mentioned above is a conventional design in the prior art, and this solution will not be elaborated on in detail.

[0031] Embodiment 3: Based on Embodiment 2, this embodiment aims to push the uninspected pipe to the center point of the upper end of the operating panel 421 after the inspection of the inner lining of the three-way composite pipe is completed.

[0032] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Fig. 9The pushing assembly 5 includes a rectangular platform 51 fixedly connected to the left side of the front upper end of the bottom plate 2, a mounting plate 4 52 is fixedly connected to the middle of the left end of the rectangular platform 51, a mounting plate 53 is fixedly connected to the left end of the mounting plate 4 52, a hollow plate 54 is fixedly connected to the middle of the left end of the mounting plate 53, a connecting rod 55 is rotatably connected to the inner surface of the hollow plate 54, a pulley 5 56 is fixedly connected to the lower end of the connecting rod 55, a conical tooth 1 57 is fixedly connected to the upper end of the connecting rod 55, a conical tooth 2 58 is rotatably connected to the upper middle part of the front end of the mounting plate 5 53, and the conical tooth 2 58 and the conical tooth 1 57 are meshed with each other, a booster assembly 59 is slidably installed on the upper end of the rectangular platform 51, and the pulley 5 56 is connected to the outer surface of the pulley 1 49 through a belt drive.

[0033] Furthermore, the boosting assembly 59 includes two assisting plates 591 that are symmetrically distributed frontward and rearward, the right ends of the two assisting plates 591 are fixedly connected with an arc plate 592, the middle parts of the lower ends of the two assisting plates 591 are fixedly connected with a limiting slide plate 593, and the middle part of the upper end of the rectangular table 51 is provided with two guide grooves 50 that are symmetrically distributed frontward and rearward, the two limiting slide plates 593 are respectively slidably connected to the inner surfaces of the two guide grooves 50, the upper parts of the left ends of the two limiting slide plates 593 are commonly fixedly connected with a connecting plate 594, the upper side of the middle part of the right end of the connecting plate 594 is rotatably connected with a threaded rod 595, the left end of the threaded rod 595 passes through the connecting plate 594 and the mounting plate five 53 and is fixedly connected to the right end of the conical tooth two 58, and the connecting plate 594 is threadedly connected to the outer surface of the threaded rod 595.

[0034] Furthermore, the four cross grooves 422 cooperate with the two guide grooves 50 .

[0035] From the above, it can be known that the rack 44 is fixedly connected to the front right side of the outer surface of the push rod 43. Therefore, when the push rod 43 moves backward with the output end of the hydraulic cylinder 42 to complete the second stage of processing, it is only necessary to start the hydraulic cylinder 42 again, so that its output end drives the push rod 43 to move backward. When the push rod 43 drives the rack 44 fixedly connected to its outer surface to move to the front side of the cylindrical gear 48, the rack 44 and the cylindrical gear 48 are meshed with each other, and then the cylindrical gear 48 drives the transmission rod 47 fixedly connected thereto to rotate, and the lower end of the transmission rod 47 is fixedly connected to a pulley 49. From the above, it can be known that the pulley 56 and the outer surface of the pulley 49 are connected together by a belt transmission. Therefore, when the transmission rod 47 rotates with the cylindrical gear 48, it can be driven by the belt transmission connection at the same time. The movable pulley 56 rotates, and then the pulley 56 drives the connecting rod 55 fixedly connected thereto to rotate, and the connecting rod 55 drives the conical tooth 1 57 to rotate, and the conical tooth 1 57 and the conical tooth 2 58 mesh with each other, so the conical tooth 2 58 starts to rotate. Since the conical tooth 2 58 is fixedly connected to the threaded rod 595, when the conical tooth 2 58 rotates, the threaded rod 595 can be driven to rotate at the same time, and the two limiting slides 593 are slidably connected to the inner surfaces of the two guide grooves 50 respectively, and then the threaded rod 595 moves to the right under the limiting action of the two limiting slides 593 and the two guide grooves 50, and at the same time, the connecting plate 594 drives the two power-assisting plates 591 to move to the right at the same time, and then the two power-assisting plates 591 drive the arc plate 592 fixedly connected at the right end thereof to move to the right, so that the composite pipe to be tested can be pushed to the right; As can be seen from the above, the four cross grooves 422 cooperate with the two guide grooves 50. Therefore, when the cross groove 422 rotates 90 degrees with the operating disk 421, it is always connected with the two guide grooves 50, so that the two limit slides 593 move to the inner cavity of the cross groove 422, and the moving distance inside the cross groove 422 is just enough to enable the arc plate 592 to push the composite tube to be tested to the upper end of the operating disk 421, so that the center point of the composite tube to be tested coincides with the center point of the operating disk 421, so that the composite tube to be tested can always be moved to the center point position of the operating disk 421 during subsequent testing; And in subsequent processing, it is only necessary to start the output end of the hydraulic cylinder 42 to move forward. At this time, the rack 44 moves forward through the cylindrical gear 48, causing the cylindrical gear 48 to reverse, thereby restoring the pushing assembly 5 as a whole to its initial state. The specific operation process is opposite to the above operation process, so it will not be described in detail.

[0036] It should be noted that the specific installation method of the hydraulic cylinder 42, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0037] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
