Description

Technical Field

[0001] This utility model relates to the field of steel pipe oxide scale detection technology, specifically a stainless steel pipe oxide scale thickness detection device. Background Technology

[0002] Pipeline oxide scale detection is of great significance: oxide scale buildup reduces the pipe's flow cross-section, decreases media flow, and affects system efficiency; it also hinders heat transfer, causing localized overheating, reducing material strength, and potentially leading to pipe bursts and other safety accidents, threatening personnel safety and stable equipment operation. Detection allows for timely monitoring of oxide scale formation and accumulation, enabling early detection of potential hazards. Based on the detection results, pipeline maintenance and cleaning can be rationally scheduled, avoiding unplanned downtime, extending pipeline lifespan, reducing operation and maintenance costs, ensuring safe, efficient, and continuous industrial production, and improving both corporate economic and social benefits.

[0003] Utility model CN211086241U discloses a scale detection device, which comprises a detection probe, a scale detector, a rolling element, an adjusting device, a connecting device, and a rotating element. The scale detector has a display screen and is communicatively connected to the detection probe. Two sets of detection probes clamp the pipe to be inspected. Each detection probe has a detection arc surface with ball grooves. The rolling element is located within the ball grooves and is in rolling connection with the detection arc surface, pressing against the pipe to be inspected. The connecting device is mounted on the detection probe and connected to the rotating element. Each of the two detection probes has a fixing element, and the adjusting device connects the two fixing elements. The adjusting device includes a first fixed cylinder, a threaded rod, an adjusting element, and a sliding element. Based on the above design, this utility model not only facilitates scale detection on pipes of different diameters, making it convenient to use, but also allows for detection at different locations on the pipe. It has a simple structure, is easy to operate, significantly improves detection efficiency, and is practical.

[0004] While the above-mentioned solutions can detect different locations on the pipeline and improve detection efficiency, the size of the detection probe cannot be changed. Therefore, when dealing with pipelines of different sizes, it is usually necessary to replace the detection probe with a matching one during actual operation. Otherwise, the detection probe will not be able to fit tightly against the pipeline, affecting the detection results. The above-mentioned solutions are difficult to replace and fix detection probes of different sizes, making them inconvenient to use. In addition, in the above-mentioned solutions, since the end of the detection probe makes rolling contact with the pipeline surface through ball bearings, it is not possible to make the detection probe fit tightly against the pipe wall during detection, which will affect the accuracy of the detection results. Therefore, to address the above problems, a stainless steel pipe oxide scale thickness detection device is proposed. Utility Model Content

[0005] To address the technical problems in comparative technologies, such as the difficulty in replacing and fixing the appropriate detection probe during use of steel pipe oxide scale detection devices, which causes inconvenience, and the inability of the detection probe to directly contact the pipe wall during operation, thus affecting the accuracy of the detection results, this utility model provides a stainless steel pipe oxide scale thickness detection device.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A stainless steel pipe oxide scale thickness detection device includes a detection frame equipped with a cooperating detection instrument main unit. The detection frame includes two sets of symmetrically arranged adjustable brackets, each equipped with a detection probe. One set of adjustable brackets has guide rods at each of its four corners, and the other set of adjustable brackets has corresponding guide holes at each of its four corners. The ends of the guide rods are threaded with spring locking components. Rolling support frames are installed at both the upper and lower ends of each adjustable bracket, with their ends slidingly contacting the outer wall of the steel pipe to be inspected. Each adjustable bracket includes a base plate with a sliding groove. Two sets of symmetrically arranged movable clamps are slidably disposed in the sliding groove, and a screw drive component for driving the movable clamps to slide is provided on the back of the base plate.

[0008] In one possible implementation, the movable clamp includes a grooved slider with grooves on both sides of its upper side. The upper and lower ends of the groove are provided with protruding ridges corresponding to the grooves. The grooved slider is slidably engaged with the groove, and a clamping piece is fixedly provided on the front end face of the grooved slider.

[0009] In one possible implementation, the clip has a slot, and sliding blocks that are slidably disposed in the slot are fixedly installed on both sides of the detection probe.

[0010] In one possible implementation, a locking screw is fixedly provided on the outer end face of the sliding block, and a locking wheel with a threaded connection is sleeved on it.

[0011] In one possible implementation, a drive block is fixedly provided on the rear end face of the grooved slider, and the screw drive includes several symmetrically arranged bearing seats on which a rotating bidirectional screw is mounted. The bidirectional screw passes through the drive block and is threadedly connected to it. In addition, a handwheel is fixedly connected to the end of the bidirectional screw.

[0012] In one possible implementation, the rolling support frame includes a support plate bolted to a base plate, and a fork fixedly connected to its end, wherein a plurality of balls arranged in a circumferential array are installed in the fork.

[0013] In one possible implementation, the spring locking element includes a compression wheel threaded to the end of the guide rod, on which a compression spring is fixedly connected.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] Two sets of sliding movable clamps are provided in the adjustable bracket. They can move closer or further away synchronously under the driving action of the screw drive. Through the cooperation of the movable clamps and the sliding blocks on both sides of the detection probe, the detection probe can be installed and fixed. Based on the above scheme, since the spacing of the movable clamps is adjustable and the two sets of adjustable brackets are slidably connected by guide rods, it is possible to install and fix detection probes of different sizes and cooperate with their normal operation. This makes the equipment highly adaptable and allows for flexible replacement of the detection probe size according to actual conditions to ensure the normal operation of the detection work and the accuracy of the detection results.

[0016] In addition, rolling support frames are provided at both the upper and lower ends of the adjustable bracket. Several balls installed on the end forks roll in contact with the pipe wall, providing support for the entire detection frame. This ensures that the detection probe fits tightly against the pipe wall without generating excessive friction, effectively reducing wear on the detection probe during sliding and extending its service life.

Detailed Implementation

[0025] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0026] like Figure 1 - Figure 3 As shown, this embodiment provides a stainless steel pipe oxide scale thickness detection device, including a detection frame 2, which is equipped with a detection instrument host 1 for cooperative operation; the detection frame 2 includes two sets of symmetrically arranged adjustable brackets 3, each of which is equipped with a detection probe 4. One set of adjustable brackets 3 is provided with guide rods 6 at the four corners, and the other set of adjustable brackets 3 is provided with corresponding guide holes 61 at the four corners. The ends of the guide rods 6 are threadedly connected with spring locking members 7. Rolling support frames 5 are installed at both the upper and lower ends of the adjustable brackets 3, and their ends slide against the outer wall of the steel pipe to be detected; the adjustable bracket 3 includes a base plate 31, on which a sliding groove is provided. Two sets of symmetrically arranged movable clamps 32 are slidably arranged in the sliding groove, and a screw drive member 33 for driving the movable clamps 32 to slide is provided on the back of the base plate 31.

[0027] Based on the above structural scheme, it is possible to fix detection probes 4 of different sizes. Specifically, the movable clamp 32 can move closer or further away synchronously under the driving action of the screw drive 33. The detection probe 4 can be installed and fixed through the movable clamp 32. Since the spacing of the movable clamp 32 is adjustable and the two sets of adjustable brackets 3 are slidably connected through the guide rod 6, it is possible to install and fix detection probes 4 of different sizes and cooperate with their normal operation. This makes the equipment highly adaptable and allows for flexible replacement of the size of the detection probe 4 according to the actual situation, so as to ensure the normal operation of the detection work and the accuracy of the detection results.

[0028] Among them, such as Figure 3 - Figure 4As shown, the movable clamp 32 includes a grooved slider 321, with grooves on both sides of its upper side. The upper and lower ends of the groove are provided with protrusions corresponding to the grooves. The grooved slider 321 is slidably engaged with the groove. The above connection scheme can ensure the stability of the sliding connection of the grooved slider 321 through the sliding engagement between the protrusions and the groove, making it less likely to deviate during sliding. In addition, a clamping piece 323 is fixedly provided on the front end face of the grooved slider 321. A slot 324 is provided on the clamping piece 323. Sliding blocks 41 are fixedly installed on both sides of the detection probe 4 and are slidably disposed in the slot 324. When installing the detection probe 4, the sliding blocks 41 at both ends can be initially fixed by engaging them into the slot 324. Then, the sliding blocks 41 are pushed back until their ends are attached to the substrate 31 to complete the positioning and installation of the detection probe 4.

[0029] In the above solution, due to the lack of constraint measures on the sliding block 41, the installed detection probe 4 is prone to sliding back and forth along the slot 324, thus affecting its normal use. Figure 3 As shown, a locking screw 42 is fixedly installed on the outer end face of the sliding block 41, and a locking wheel 43 with a threaded connection is sleeved on it. After the detection probe 4 is positioned and installed, tightening the locking wheel 43 can fix the position of the detection probe 4 through the friction between it and the clamping piece 323.

[0030] In addition, to complete the driving of the movable clamp 32, such as Figure 4 As shown, a drive block 322 is fixedly installed on the rear end face of the grooved slider 321. The screw drive component 33 includes several symmetrically arranged bearing seats 331, on which a rotating bidirectional screw 332 is installed. The bidirectional screw 332 passes through the drive block 322 and is threadedly connected to it. In addition, a handwheel 333 is fixedly connected to the end of the bidirectional screw 332. When the bidirectional screw 332 is rotated by turning the handwheel 333, it will drive the drive block 322, which is threaded at both ends, to move closer or further away synchronously. This will drive the grooved slider 321 fixedly connected to the drive block 322 to move closer or further away synchronously, thereby completing the overall drive of the movable clamp 32 and realizing the clamping and installation of the detection probe 4.

[0031] like Figure 5 As shown, the rolling support frame 5 includes a support plate 51, which is bolted to the base plate 31, and a fork 52 is fixedly connected to its end. A number of balls 53 arranged in a circumferential array are installed in the fork 52. The balls 53 installed on the end fork 52 roll in contact with the pipe wall, thus supporting the entire detection frame 2. This ensures that the detection probe 4 fits tightly against the pipe wall without generating excessive friction, effectively reducing the wear of the detection probe 4 during sliding and extending its service life.

[0032] like Figure 6As shown, the spring locking member 7 includes a compression wheel 71 threadedly connected to the end of the guide rod 6, on which a compression spring 72 is fixedly connected. When the compression wheel 71 is turned, it will apply an inward thrust to the substrate 31 in contact with it through the compression spring 72, causing it to slide along the guide rod 6 toward another substrate 31, thereby clamping the entire detection frame 2 on the outside of the tube wall. Since the compression spring 72 is in a compressed state during operation, it can provide an outward thrust after installation, which plays a certain role in preventing loosening.

[0033] The working principle and usage process of this utility model:

[0034] When the bidirectional screw 332 is rotated by turning the handwheel 333, it will drive the drive blocks 322 connected by threads at both ends to move closer or further away synchronously, thereby driving the grooved slider 321 fixedly connected to the drive block 322 to move closer or further away synchronously, thus completing the overall drive of the movable clamp 32 and realizing the clamping and installation of the detection probe 4. When installing the detection probe 4, the sliding blocks 41 at both ends can be initially fixed by inserting them into the slots 324. Then, the sliding blocks 41 are pushed back until their ends are attached to the substrate 31 to complete the positioning and installation of the detection probe 4. After installation, the detection probe 4 can be symmetrically attached to the outside of the pipe wall to complete the detection of oxide scale on the pipe wall.

[0035] During the testing process, the rolling support frame 5 rolls against the pipe wall through several balls 53 installed on the end fork 52, thus providing overall support for the testing frame 2. This ensures that the testing probe 4 fits tightly against the pipe wall without generating excessive friction, effectively reducing the wear on the testing probe 4 during sliding and extending its service life.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
