[0002] Pressure pipeline refers to all pipelines that are subjected to internal or external pressure, regardless of the medium inside the pipe. Pressure pipeline is a part of the pipeline. Pipeline is used to transport, distribute, mix, separate, discharge, meter, control and stop the flow of fluid. It is an assembly composed of pipes, pipe fittings, flanges, bolted connections, gaskets, valves, other components or pressure-bearing parts and supports. The application range of pressure pipeline is very wide, such as mechanical manufacturing, aerospace, energy pipelines and biomedical engineering. It is very important to accurately measure the internal diameter of the pressure pipeline. By measuring the value, the wear of the pipeline can be known, and the need to replace the pressure pipeline can be determined based on the measured data. Therefore, we have launched a pressure pipeline laser measurement device.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 9 The present invention provides a technical solution: a pressure pipeline laser measuring device, comprising a mounting plate 1 and a pipeline body 2, wherein an electric push rod 3 and a through column 4 are fixedly connected to one side of the mounting plate 1 close to the pipeline body 2, a push plate 5 is fixedly connected to the output end of the electric push rod 3, an adaptive rotating cleaning component 6 is provided on the side of the push plate 5 close to the pipeline body 2, an inner supporting component 7 is integrally formed at one end of the through column 4 away from the mounting plate 1, an outer clamping component 9 is provided on the outer ring of the adaptive rotating cleaning component 6, and a dust collecting component 8 is fixedly connected to the side of the adaptive rotating cleaning component 6 close to the mounting plate 1.

[0032] In this embodiment, Figures 1 to 3 and Figures 7 to 9As shown, the adaptive rotary cleaning assembly 6 includes a piston rod 601 fixedly connected to the side of the push plate 5 away from the electric push rod 3, a piston sheet 602 is integrally formed in the middle of the piston rod 601, and the end of the piston rod 601 away from the push plate 5 is rotatably connected to a rotating column 603, and a protruding column 604 is integrally formed on the outer side of one end of the rotating column 603, and the protruding column 604 is slidably arranged inside the spiral groove 605, and the spiral groove 605 is arranged on the inner wall surface of the spiral cylinder 606, and the outer surface of the rotating column 603 The rotating column 603 is connected to the rotating sleeve 608 through the rectangular convex strip 607. The rotating sleeve 608 is rotatably connected to the middle of the fixed frame 609, and the outer surface of the rotating sleeve 608 is integrally formed with a tri-fold rod 6010. The tri-fold rod 6010 is composed of two horizontal rods and two vertical sections. The two horizontal rods of the tri-fold rod 6010 are fixedly connected to the opposite side with a spring telescopic rod 6011. The end of the spring telescopic rod 6011 away from the tri-fold rod 6010 is respectively fixed. The outer cleaning block 6012 and the inner cleaning block 6013 are connected, and the oil storage cylinder 6014 is fixedly connected to the side of the three-fold rod 6010 close to the piston rod 601. The outer cleaning block 6012 and the inner cleaning block 6013 are fixedly installed with a laser measuring instrument 6015 on one side. The three-fold rod 6010 is provided with three groups, and the oil storage cylinder 6014 is fixedly connected between the three groups of three-fold rods 6010, and the inner wall of the oil storage cylinder 6014 is slidably fitted with the outer ring of the piston plate 602. The piston rod 601 and the rotating column 603 are fixedly mounted with a laser measuring instrument 6015. The middle part is hollow, wherein the cross section of the middle hole of the piston rod 601 is square, while the cross section of the middle hole of the rotating column 603 is circular, and the column 4 is divided into a thick section and a thin section, the thick section is connected to the mounting plate 1, and the thin section penetrates the piston rod 601 and the rotating column 603 and extends to the middle of the inner support assembly 7 and is fixedly connected thereto, the outer cleaning block 6012 and the inner cleaning block 6013 are trapezoidal structures, and bristles are provided on one side of the trapezoidal bottom edge where the outer cleaning block 6012 and the inner cleaning block 6013 are close to each other;When it is necessary to measure the pressure pipeline, hold the handle of the mounting plate 1, and then partially insert the inner support assembly 7 into the pipeline body 2. During the insertion process, the end of the pipeline body 2 will first contact the inclined surfaces of the outer cleaning block 6012 and the inner cleaning block 6013, and gradually squeeze the outer cleaning block 6012 and the inner cleaning block 6013 in the direction away from the pipeline body 2, so that the two groups of cleaning blocks compress the spring telescopic rod 6011 until the end of the pipeline body 2 contacts the vertical section of the three-fold rod 6010. At this time, the measuring device is initially pushed into place, and then the electric push rod 3 is started to extend. The electric push rod 3 will push the push plate 5 along the axis of the pipeline body 2 toward the inside of the pipeline body 2. In this process, the push plate 5 will drive the piston rod 601 connected to it to move synchronously, and the piston rod 601 will simultaneously drive the piston plate 602 and the rotating column 603 to move. When the piston plate 602 moves along the oil storage cylinder 6014, the hydraulic oil in the oil storage cylinder 6014 can be pushed out. The oil is squeezed into the dust suction assembly 8 and the outer clamping assembly 9 through the oil hose 802 and the hydraulic hose 901 respectively, and the rotating column 603 will first push the spiral drum 606 to move inside the pipeline body 2. When the spiral drum 606 moves, it will drive the inner support assembly 7 to operate. When the inner support bar 705 in the inner support assembly 7 contacts the inner wall of the pipeline body 2 and cannot continue to be stretched, at this time, due to the continued extension of the electric push rod 3, it will continue to push the rotating column 603 forward, and the outer surface of one end of the rotating column 603 will be The raised column 604 on the surface is squeezed by the spiral groove 605 and slides along the spiral groove 605, causing the rotating column 603 to rotate. When the rotating column 603 rotates, the rectangular convex strip 607 on the outer surface drives the rotating sleeve 608 to rotate. The rotation of the rotating sleeve 608 drives the three-fold rod 6010 to revolve around the rotating sleeve 608. The rotation of the rotating sleeve 608 drives the inner cleaning block 6013 and the outer cleaning block 6012 to revolve synchronously, thereby cleaning the inner and outer surfaces of the pipe body 2. Figure 2From the left viewing angle in the figure, the revolution direction of the three-fold rod 6010 is affected by the rotation direction of the spiral groove 605 to rotate clockwise, and the laser measuring instrument 6015 is installed on the left part of the cleaning block, that is, the laser measuring instrument 6015 measures the surface of the pipeline body 2 that has been cleaned by the cleaning block, to prevent impurities adhering to the surface of the pipeline body 2 and causing deviations in the measurement process. In addition, the structure can also measure the inner and outer flatness and ovality of the pipeline body 2 at the same time, and the measurement result is more comprehensive. The setting of the spring telescopic rod 6011 makes the inner cleaning block 6013 and the outer cleaning block 6012 adaptively fit the inner and outer walls of the pipeline, so as to adapt to pressure pipelines of different thicknesses and diameters, thereby enhancing the adaptability of the laser measuring device. In addition, there are two points to note. One is the shape design of the through hole in the middle of the rotating column 603 and the piston rod 601, which is divided into a thick section and a thin section through the column 4. The segments are all rectangular structures, and the outer surface of the thin segment of the through-column 4 does not contact the inner wall of the circular hole in the middle of the rotating column 603, so that the through-column 4 will not affect the rotation of the rotating column 603, and the inner diameter of the hole in the middle of the piston rod 601 is only slightly larger than the cross-sectional size of the through-column 4, so that the piston rod 601 can only slide along the axial direction of the through-column 4 without rotating. Secondly, it should be noted that the rotation of the rotating column 603 needs to overcome the friction between the raised column 604 and the spiral groove 605, the friction between the inner cleaning block 6013 and the outer cleaning block 6012 and the inner and outer surfaces of the pipe body 2, and the self-weight of the adaptive rotating cleaning component 6, the dust collection component 8 and the outer clamping component 9. The above forces that need to be overcome are greater than the resilience of the reset spring 703. Therefore, when the rotating column 603 is pushed into the pipe body 2, it will squeeze the reset spring 703 and then start to rotate.

[0033] In this embodiment, Figure 2 , Figure 3 and Figure 8As shown, the inner support assembly 7 includes a mounting frame 701 fixedly connected to the thin section of the penetrating column 4, the mounting frame 701 is integrally formed at one end of the fixed cylinder 702, a return spring 703 is fixedly connected between the mounting frame 701 and the spiral cylinder 606, a mounting groove is provided on the outer surface of the fixed cylinder 702, and a driven connecting rod 704 is rotatably connected to the inside of the mounting groove through a connecting shaft, an inner support bar 705 is hinged at one end of the driven connecting rod 704 away from the fixed cylinder 702, a side of the inner support bar 705 away from the fixed cylinder 702 is connected to the outer surface of the spiral cylinder 606 through an active connecting rod 706, and a side of the inner support bar 705 close to the pipe body 2 is opened An anti-slip groove is provided, and the inner wall of the fixed cylinder 702 is fixedly connected to the fixed frame 609; when the rotating column 603 pushes the spiral cylinder 606 to move toward the inside of the pipeline body 2, the spiral cylinder 606 will compress the reset spring 703 while driving the active connecting rod 706 to gradually become perpendicular to the spiral cylinder 606. In the process of the active connecting rod 706 gradually becoming perpendicular to the spiral cylinder 606, the inner support bar 705 will be stretched toward the direction close to the inner wall of the pipeline body 2 until the inner support bar 705 expands and contacts the inner wall of the pipeline body 2. At this time, the laser measuring device is fixed in the middle of the pipeline body 2 to ensure that no shaking will occur during subsequent measurements to affect the measurement results.

A hole is opened between the oil delivery channel 801 and the oil storage cylinder 6014 to communicate. The hydraulic oil enters the hydraulic oil chamber 803 from the oil delivery channel 801 through the oil delivery hose 802 and pushes the square piston 804 in the hydraulic oil chamber 803. The movement of the square piston 804 will drive the connecting block 806 to move between the power supply 809 and the dust suction fan 808 through the piston push rod 805. The connecting block 806 connects the power supply 809 and the connecting head on the dust suction fan 808. After the dust suction fan 808 is powered on, the dust on the side of the air inlet 8010 is sucked into the dust suction bin 807. The air inlet 8010 in this structure is opposite to the outer cleaning block 6012 and the inner cleaning block 6013, so that the impurities and dust brushed off by the cleaning blocks can be sucked into the dust suction bin 807 in time, preventing the brushed dust from floating in the air and causing refraction interference to the laser measuring instrument 6015, resulting in inaccurate measurement results.
