Description

Technical Field

[0001] This invention relates to special equipment testing technology, and more specifically to an auxiliary device for special equipment testing. Background Technology

[0002] Pressure pipelines, as special equipment with high risks, are officially included in safety management and supervision regulations. They not only need to ensure the airtightness of the pipeline to prevent leakage during the flow of the medium, but also need to withstand a certain pressure (internal or external pressure). This places higher requirements on the sidewalls of pressure pipelines. Therefore, all pressure pipelines produced need to undergo strict testing.

[0003] Detecting defects in the appearance of pressure pipelines is one of the most common inspection methods. This typically involves using image acquisition devices to inspect the outer wall of the pipeline or visual inspection to determine if cracks have appeared. When applying for this invention, the applicant, through a search, discovered Chinese patent publication CN114720484B, which discloses an auxiliary device for special equipment inspection. This device includes a scanning gun body, a battery pack installed at the bottom of the scanning gun body, a universal adjustment assembly connected to the port of the scanning gun body via a telescopic sleeve assembly, a scanning assembly connected to the other side of the universal adjustment assembly, a scanning display screen connected to the top of the telescopic sleeve assembly via a bracket, and a wire retractor at the bottom of the telescopic sleeve assembly. A column charging base is fixedly mounted on the frame of the wire retractor. During operation, multiple image acquisition cameras are evenly positioned on the inner and outer sleeves, completely covering the outer circumference of the pipe wall. This allows for comprehensive image acquisition of the pipe's outer wall. After image acquisition, the images are transferred to a scanning display screen and simultaneously stored on a memory card on the screen for subsequent image analysis. This effectively solves the problems of current image acquisition devices being unable to simultaneously acquire images of the pipe's circumference and the low efficiency of manual acquisition. However, since the scanning components move along the axial direction of the pressure pipe, each image acquisition unit actually acquires an image of a rectangular area. This makes it impossible to completely detect pressure pipes of different diameters, resulting in insufficient adaptability in practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary device for testing special equipment, so as to overcome the above-mentioned shortcomings in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary device for special equipment inspection, comprising an inspection platform equipped with a processing system, conveying grooves at both ends of the inspection platform, electrically driven wheels for conveying pressure pipelines symmetrically arranged on both sides inside the conveying grooves, an installation groove in the middle of the inspection platform, two support rods slidably connected to the inner side of the installation groove, an inspection ring between the two support rods, and a plurality of image acquisition cameras equidistantly arranged on the inspection ring; The detection ring includes multiple support shells, each with a sliding groove inside. An intermediate block is provided between adjacent support shells. Extension plates that slide and connect to the inner side of the sliding groove are symmetrically installed on both sides of the intermediate block. A limiting groove communicating with the sliding groove is provided on the surface of the support shell. Limiting blocks corresponding to the limiting groove are installed at both ends of the extension plates. The image acquisition camera is equidistantly installed on the surfaces of the support shells and the intermediate block. An adjustment unit is provided on the outside of the support rod, which is used to adjust the distance between the two support rods.

[0006] Furthermore, the adjustment unit includes a lifting sleeve that is slidably sleeved on the outside of the support rod. A first crossbar is installed on the opposite side of each of the two lifting sleeves. The two first crossbars are slidably connected to the same support sleeve. A second crossbar is installed on the opposite side of each of the two support rods. The two second crossbars are slidably connected to the same connecting sleeve.

[0007] Furthermore, guide grooves are symmetrically provided on both sides of the bottom surface of the mounting groove. A guide block is installed at the bottom of the support rod and slidably connected to the inner side of the guide groove. A guide frame is installed at the bottom of the mounting groove. A lifting plate is slidably connected to the inner side of the guide frame. A drive rod is rotatably connected between the lifting plate and the two guide blocks. The drive rod is inclined. An adjusting electric rod is installed at the top of the guide frame. When the adjusting electric rod drives the lifting plate to move downward, the drive rod drives the two support rods to move in a direction away from each other.

[0008] Furthermore, the guide block is convex in shape, and the shape and size of the guide groove are adapted to the guide block.

[0009] Furthermore, the electric drive wheel is tilted.

[0010] Furthermore, an auxiliary unit is provided between the extension plate and the support sleeve. The auxiliary unit includes a first rack and a second rack respectively installed on the two extension plates at opposite ends.

A synchronous gear is rotatably connected to the inner side of the groove. The first rack and the second rack located inside the same support sleeve mesh on both sides of the same synchronous gear.

[0011] Furthermore, guide grooves are provided at both the upper and lower ends of the inner wall of the support sleeve, and guide posts are installed on the upper and lower sides of the extension plates on both sides away from each other. The guide posts are slidably connected to the inner side of the guide grooves.

[0012] Furthermore, several mounting blocks are equidistantly installed on the surfaces of the support shell and the intermediate block along an arc shape. The surface of each mounting block has an embedded groove, and the image acquisition camera is embedded in the embedded groove.

[0013] Compared with the prior art, the auxiliary device for special equipment testing provided by the present invention has the following beneficial effects: 1.

As a result, the distribution of the image acquisition cameras on the inspection ring remains relatively uniform after adjustment, which is beneficial for better image acquisition of the pressure pipeline surface.

[0015] 3.

[0019] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] Please see Figures 1-8 An auxiliary device for testing special equipment includes a testing platform 1 equipped with a processing system. The testing platform 1 has conveying grooves 2 at both ends. Electric drive wheels 21 for conveying pressure pipelines are symmetrically arranged on both sides inside the conveying grooves 2. The electric drive wheels 21 are inclined. The testing platform 1 has a mounting groove 22 in the middle. Two support rods 23 are slidably connected to the inner side of the mounting groove 22. A testing ring 24 is arranged between the two support rods 23. Several image acquisition cameras 25 are equidistantly arranged on the testing ring 24.

[0022] It should be noted that the image acquisition camera 25 is connected to the image processing system. The image acquisition camera 25 acquires images of the surface of the pressure pipe conveyed by the electric drive wheel 21, and then transmits the acquired image information to the image processing system. The processing system then identifies and analyzes the images to determine the actual state of the pressure pipe surface.

[0023] In addition, the electric drive wheel 21 is driven by a motor, which can smoothly transport pressure through the pipeline during rotation.

[0024] The detection ring 24 includes multiple support housings 3. The interior of each support housing 3 has a sliding groove 31. An intermediate block 32 is provided between adjacent support housings 3. An extension plate 33 that is slidably connected to the inner side of the sliding groove 31 is symmetrically installed on both sides of the intermediate block 32. A limiting groove 34 that communicates with the sliding groove 31 is provided on the surface of the support housing 3. A limiting block 35 corresponding to the limiting groove 34 is installed at both ends of the extension plate 33. An image acquisition camera 25 is equidistantly installed on the surfaces of the support housing 3 and the intermediate block 32.

[0025] It should be further explained that the support sleeve 3, extension plate 33, and other structures that need to deform to a certain extent during the adjustment of the detection ring 24 are all made of materials with high strength and certain toughness, so that they can undergo small-amplitude bending changes during the adjustment of the detection ring 24 to meet the changes in the size of the detection ring 24.

[0026] An adjustment unit is provided on the outside of the support rod 23, which is used to adjust the distance between the two support rods 23.

[0027] During operation, the pressure pipe is conveyed forward by the electric drive wheel 21, and the pressure pipe passes through the middle of the detection ring 24 during the movement, so that the image acquisition camera 25 set on the detection ring 24 can acquire images of the surface of the pressure pipe. During the inspection process, when it is necessary to inspect a larger pressure pipeline, the adjustment unit drives the two support rods 23 to move away from each other, so that the two support sleeves 3 connected to the support rods 23 move away from each other. Under the action of this traction force, the extension plate 33 can be moved out from the inside of the support sleeve 3, so that the size of the inspection ring 24 can be increased, thereby meeting the needs of inspecting pressure pipelines of different specifications.

[0028] The specific mechanism of the adjustment unit is described below. The adjustment unit includes a lifting sleeve 4 that is slidably sleeved on the outside of the support rod 23. A first crossbar 41 is installed on the opposite side of both lifting sleeves 4. The two first crossbars 41 are slidably connected to the outside of the same support sleeve 42. A second crossbar 43 is installed on the opposite side of both support rods 23. The two second crossbars 43 are slidably connected to the outside of the same connecting sleeve 44. A lifting electric rod 45 is installed on the top of the support sleeve 42. The top of the telescopic end of the lifting electric rod 45 is fixedly connected to the connecting sleeve 44.

[0029] It should be added that guide grooves 46 are symmetrically provided on both sides of the bottom surface of the mounting groove 22. The bottom of the support rod 23 is equipped with guide blocks 47 that are slidably connected to the inner side of the guide grooves 46. The bottom of the mounting groove 22 is equipped with a guide frame 48. The inner side of the guide frame 48 is slidably connected with a lifting plate 49. The lifting plate 49 and the two guide blocks 47 on both sides are rotatably connected with drive rods 410. The drive rods 410 are inclined. The top of the guide frame 48 is equipped with an adjusting electric rod 411. When the adjusting electric rod 411 drives the lifting plate 49 to move downward, the drive rod 410 drives the two support rods 23 to move in a direction away from each other.

[0030] Furthermore, the guide block 47 is convex in shape, and the shape and size of the guide groove 46 are compatible with the guide block 47, so that the movement of the support rod 23 can be stably guided by the cooperation of the guide block 47 and the guide groove 46.

[0031] During operation, when it is necessary to increase the diameter of the detection ring 24 to meet the requirements of large-scale pressure pipeline inspection, firstly, the electric rod 411 is adjusted to drive the lifting plate 49 to move downward, so that the drive rod 410 at the bottom of the lifting plate 49 can push the two lifting sleeves 4 to move away from each other synchronously. The movement of the lifting sleeves 4 drives the support rod 23 to move, and the movement of the support rod 23 will apply an outward traction force to the support sleeve 3 connected to it, so that the detection ring 24 tends to increase in diameter. Under this trend, the other support sleeves 3 will also be subjected to an outward traction force, so that the extension plates 33 inside all the support sleeves 3 will move to the outside of the support sleeves 3 to meet the circumferential tolerance, thus increasing the size of the detection ring 24. After the size of the detection ring 24 is adjusted, the connecting sleeve 44 is driven to move upward by the lifting electric rod 45. The upward movement of the connecting sleeve 44 drives the support rod 23 to move upward, and the upward movement of the support rod 23 drives the detection ring 24 to move upward. This allows the position and height of the detection ring 24 to be adjusted so that the detection ring 24 can maintain a relatively concentric state with the pressure pipeline to be tested, thus facilitating the surface inspection of the pressure pipeline.

[0032] Example 2

[0033] Please see Figures 3-4This embodiment provides a technical solution based on the above embodiment: an auxiliary unit is provided between the extension plate 33 and the support sleeve 3. The auxiliary unit includes a first rack 5 and a second rack 51 respectively installed on the two sides of the extension plate 33 at opposite ends. The teeth on the first rack 5 and the teeth on the second rack 51 are located on the opposite side surfaces. The two extension plates 33 are provided with matching grooves 52 corresponding to the first rack 5 and the second rack 51 respectively. The inner side of the sliding groove 31 is rotatably connected to a synchronous gear 53. The first rack 5 and the second rack 51 located inside the same support sleeve 3 mesh on both sides of the same synchronous gear 53.

[0034] Furthermore, guide grooves 54 are provided at both the upper and lower ends of the inner wall of the support sleeve 3, and guide posts 55 are installed on both the upper and lower ends of the two side extension plates 33 that are far apart from each other. The guide posts 55 are slidably connected to the inner side of the guide grooves 54.

[0035] During the adjustment process, with the cooperation of the synchronous gear 53, the movement of the first rack 5 and the second rack 51 that mesh externally are synchronized, so that the two extension plates 33 inside the same support sleeve 3 can move outward synchronously. Therefore, when the traction force is applied during adjustment, the two extension plates 33 inside the support sleeve 3 that are directly subjected to force slide outward synchronously, so that the overall diameter of the detection ring 24 tends to increase. Under the action of this trend, the remaining support sleeves 3 all receive the traction force to move outward, so that the extension plates 33 inside all the support sleeves 3 can move outward relatively evenly, so that the detection ring 24 gradually opens.

[0036] Example 3

[0037] Please see Figure 7 Based on the above embodiments, this embodiment provides a technical solution: a plurality of mounting blocks 6 are installed at equal intervals along the arc shape on the surfaces of the support shell 3 and the intermediate block 32, and an embedded groove 61 is opened on the surface of the mounting block 6, and the image acquisition camera 25 is embedded in the embedded groove 61.

[0038] When the diameter of the detection ring 24 is increased to detect large-diameter pressure pipes, the image acquisition camera 25 can be installed on the empty mounting block 6 according to the increase in the actual detection range, so that the number of image acquisition cameras 25 on the detection ring 24 can be selected according to the actual pressure pipe being detected.

[0039] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
