Description

Technical Field

[0001] This utility model relates to the technical field of measuring rubber-lined pipes, and in particular to a centrally located circumferential full-inspection composite probe mechanism. Background Technology

[0002] In rubber-lined pipelines, the hardness and thickness of the lining are crucial indicators for ensuring pipeline operation, and measuring them after a certain period of operation is also an important task. However, in the inspection of rubber-lined pipelines, current technology mainly relies on manual handheld inspection instruments for localized inspections near the pipe opening, which cannot effectively detect the hardness and thickness of the lining deep within the pipeline (e.g., several meters to tens of meters). Traditional equipment has the following drawbacks: First, limited inspection range: it cannot penetrate deep into the pipeline and is difficult to cover the entire length of long pipelines; second, low inspection efficiency: manual item-by-item or point-by-point inspection can only detect one of the two aspects of the lining hardness or thickness, and can only inspect one location or area, failing to achieve 360° circumferential full coverage; third, poor data traceability: manual data recording is prone to errors and lacks real-time acquisition and storage capabilities; fourth, insufficient adaptability: it cannot automatically adapt to different pipe diameters and requires frequent manual adjustments.

[0003] The patent CN202220994964.2, entitled "A Pipe Size Measuring Device", proposes a pipe size measuring device. However, in reality, most pipes are circular. This patent does not solve the problem of how to keep the measuring device stably located at the center of the circular pipe in the circumferential direction, i.e., the problem of centering in the circumferential direction. Utility Model Content

[0004] The purpose of this invention is to solve the problems of limited detection range, low detection efficiency, poor data traceability, insufficient adaptability, and inability to perform centered circumferential inspection in the surface hardness and thickness of traditional pipe lining rubber layers in the prior art. Therefore, a centered circumferential full inspection composite probe mechanism is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A centrally located circumferential full-inspection composite probe mechanism includes a cylindrical component compartment and fixed shafts. The component compartment has a square opening on its wall, and a fixed base is provided inside the compartment. A hardness measuring probe and a thickness measuring probe are fixed side-by-side on the fixed base. There are two fixed shafts, which are vertically and symmetrically connected to both ends of the component compartment and are both connected inside the compartment by bearings. The central axes of the component compartment, the two fixed shafts, and the fixed shafts are collinear. From the end of each fixed shaft not connected to the component compartment, a tail cap, an adjustable nut, an adaptive spring, a propulsion bracket, and a fixed bracket are sequentially connected. The propulsion bracket and the fixed bracket are jointly connected to a Y-shaped roller bracket.

[0007] Preferably, two identical slides are symmetrically fixed on the inner side of one end of the component compartment, and the center line of the slides is perpendicular to the square opening of the component compartment; two slide rails that match the slides are symmetrically provided on the fixing base.

[0008] Preferably, a lifting rack aligned with the slide rail is fixed on the fixed base; a motor base is provided inside the component compartment, on which a lifting rotary motor is fixed, and a lifting cylindrical gear is fixed on the output shaft of the lifting rotary motor, which meshes with the lifting rack.

[0009] Preferably, one of the fixed shafts has a large cylindrical gear fixed outside the component compartment; a rotary motor is fixed inside the component compartment, the output shaft of the rotary motor extends out of the end of the component compartment and a small cylindrical gear is fixed thereon, the small cylindrical gear meshing with the large cylindrical gear; a protective cover is designed on the outside of the small cylindrical gear and the large cylindrical gear, and the protective cover is fixed to the component compartment.

[0010] Preferably, the propulsion bracket is disc-shaped and has three U-shaped interfaces symmetrically arranged around its circumference; the fixing bracket is disc-shaped and has three U-shaped interfaces symmetrically arranged around its circumference, which are the same as the U-shaped interfaces on the propulsion bracket.

[0011] Preferably, the U-shaped interface of the propulsion bracket is connected to the tail of the roller bracket via a rotating shaft; the U-shaped interface of the fixed bracket is connected to a Y-shaped adjusting hinge block via a rotating shaft and connected to its tail; the head of the adjusting hinge block is connected to the middle of the roller bracket.

[0012] Preferably, the head of the roller bracket is connected to a bearing by a pin and has a roller.

[0013] Preferably, one end of the adaptive spring abuts against the propulsion bracket, and the other end abuts against the adjustable nut.

[0014] Compared with the prior art, this utility model provides a centrally located circumferential full-inspection composite probe mechanism, which has the following beneficial effects.

[0015] 1. This utility model can be placed inside a pipe and automatically advanced by rollers, allowing it to penetrate deep into the pipe and detect the surface hardness and thickness of the inner lining rubber layer within several meters or even tens of meters.

[0016] 2. This utility model uses a fixed base to fix the thickness probe and hardness probe of the rubber lining layer together in a reasonable position, so that two kinds of test data can be obtained at the same time in one operation. At the same time, this utility model uses a rotary motor to rotate the component chamber within a 360° range through the meshing of the cylindrical small gear and the cylindrical large gear, so as to achieve full coverage of circumferential detection.

[0019] 5. This utility model ensures that the central axes of the component compartment and the two fixed shafts are collinear, and with the help of the fixed bracket and the rolling bracket, the measuring device can be stably located at the center of the circular pipe in the circumferential direction during the measurement process, that is, centered in the circumferential direction.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figure 1-8A centrally located circumferential full-inspection composite probe mechanism includes a cylindrical component compartment 2 and a fixed shaft 3. The component compartment 2 has a square opening on its wall, from which a component compartment cover 27 is connected. A fixed base 1 is located inside the component compartment 2, on which a hardness measuring probe 11 and a thickness measuring probe 12 are fixed side-by-side. This invention uses the fixed base to fix the rubber lining thickness measuring probe 11 and the hardness measuring probe 12 together in a reasonable position, allowing for simultaneous acquisition of two types of test data in a single operation. A high-frame-rate image acquisition device 13 is installed at one end of the hardness measuring probe 11, ensuring real-time acquisition of the data measured by the hardness measuring probe 11. The thickness measuring probe 12 can transmit data to the data acquisition end via its own data cable, ensuring that all detected data is stored and guaranteeing reliable traceability of the measurement data. The specific location and installation method of the high-frame-rate image acquisition device 13 and the data cable are not specifically shown in the accompanying drawings and can be freely selected according to individual needs. The number of fixed shafts 3 is... Two fixed shafts 3 are vertically and symmetrically connected to both ends of the component compartment 2 and are both connected inside the component compartment 2 by bearings 26. This ensures that the component compartment 2 can rotate smoothly while also being able to withstand a certain amount of tension. The central axes of the component compartment 2 and the two fixed shafts 3 are collinear. The end of the fixed shaft 3 that is not connected to the component compartment 2 is connected in sequence from the end to the tail cover 7, the adjustable nut 6, the adaptive spring 5, the push bracket 41, and the fixed bracket 40. The push bracket 41 and the fixed bracket 40 are connected together to a Y-shaped roller bracket 42. The tail cover 7 is used to limit and ensure that the components on the entire fixed shaft 3 are installed stably and will not detach from the fixed shaft 3.

[0032] Two identical slide rails 21 are symmetrically fixed to the inner side of one end of the component compartment 2, with the center line of the slide rails 21 perpendicular to the square opening of the component compartment 2. Two slide rails 15, matching the slide rails 21, are symmetrically provided on the fixing base 1. A lifting rack 14, aligned with the slide rails 15, is fixed on the fixing base 1. A motor base 29 is provided inside the component compartment 2, on which a lifting rotary motor 23 is fixed. A lifting cylindrical gear 22 is fixed to the output shaft of the lifting rotary motor 23, and the lifting cylindrical gear 22 meshes with the lifting rack 14. The forward and reverse rotation of the lifting rotary motor 23 drives the forward and reverse rotation of the lifting cylindrical gear 22. Through the meshing of the lifting cylindrical gear 22 with the lifting rack 14, the forward and reverse rotation of the lifting cylindrical gear 22 is converted into the descent and ascent of the lifting rack 14. Simultaneously, the descent and ascent of the composite probe structure of the lifting rack 14 are achieved. This satisfies the requirement that the composite probe assembly can be used for measurements in pipes of different diameters, and that the composite probe assembly can be completely hidden inside the component compartment 2 without affecting its passage within the pipe.

[0033] One of the fixed shafts 3 has a large cylindrical gear 25 fixed to the outside of the component compartment 2. A rotary motor 28 is fixed inside the component compartment 2. The output shaft of the rotary motor extends from the end of the component compartment 2, and a small cylindrical gear 24 is fixed on it. The small cylindrical gear 24 meshes with the large cylindrical gear 25. A protective cover 31 is designed around the small cylindrical gear 24 and the large cylindrical gear 25. The protective cover 31 is fixed to the component compartment 2 to prevent dust or other foreign objects from entering the meshing area of ​​the small cylindrical gear 24 and the large cylindrical gear 25 and damaging the gear set. The forward and reverse rotation of the rotary motor 28 drives the component compartment 2 to rotate within a 360° range through the meshing of the small cylindrical gear 24 and the large cylindrical gear 25, achieving full coverage of circumferential inspection.

[0034] The propulsion bracket 41 is disc-shaped with three symmetrically arranged U-shaped interfaces 46 on its circumference. The fixed bracket 40 is also disc-shaped with three symmetrically arranged U-shaped interfaces 46 identical to those on the propulsion bracket 41. The U-shaped interfaces of the propulsion bracket 41 are connected to the tail of the roller bracket 42 via a rotating shaft. The U-shaped interfaces of the fixed bracket 40 are connected to a Y-shaped adjusting hinge block 45 via a rotating shaft and connected to its tail. The head of the adjusting hinge block 45 is connected to the middle of the roller bracket 42. The head of the roller bracket 42 is connected to a roller 43 via a pin 44 and a bearing 26. One end of the adaptive spring 5 presses against the propulsion bracket 41, and the other end presses against the adjustable nut 6. To ensure good passage and stable centering within the pipeline, the fixed shaft 3 is designed with the propulsion bracket 41 and the fixed bracket 40 connected together by the roller bracket 42. The roller bracket is connected by a pin to ensure good adjustability. Roller 43 is connected to the propulsion bracket 41 and the fixed bracket 40 via bearing 26 and pin 44. Bearing 26 converts the sliding friction between roller 43 and the pipe wall into roller friction, reducing the frictional force with the pipe wall, reducing its own power consumption, and ensuring good throughput. The propulsion bracket 41 is designed with an adaptive spring 5 at the rear, ensuring that no adjustment is needed within a certain pipe diameter range, and automatically adapting to changes in pipe diameter within this range. At the same time, an adjustable nut 6 is also designed at the rear end, which can be adjusted to adapt to different pipe diameter ranges when larger changes in pipe diameter are required.

[0035] Working process: After connecting all the components or structures of this utility model, adjust the adjustable nut 6 according to the pipe diameter to ensure that the rollers 43 in the same circumferential direction are tightly against the pipe wall. Start this utility model, the rollers 43 rotate and move along the pipe. The lifting rotary motor 23 starts its forward and reverse rotation, which drives the lifting cylindrical gear 22 to rotate forward and reverse, which in turn converts into the descent and ascent of the lifting rack 14. At the same time, the composite probe group of the lifting rack 14 descends and ascends, so that the hardness probe 11 and the thickness probe 12 reach the appropriate measurement height. Simultaneously, the rotary motor 28 starts its forward and reverse rotation, which drives the component chamber 2 to rotate within a 360° range through the gear meshing of the cylindrical pinion 24 and the cylindrical gear 25, so as to achieve full coverage of circumferential detection. If you want to measure a certain point or a certain area, you can turn off the rotary motor 28 when it rotates to the appropriate position, so that the composite probe group is aligned with the point or area for measurement. After the measurement is completed, the high frame rate image acquisition unit 13 ensures that the data measured by the hardness probe is acquired in real time. The thickness probe can transmit the data to the data acquisition end through its own data cable, ensuring that all the detected data can be stored for reading.
