Description

Technical Field

[0001] This invention relates to the field of Gray bus line inspection technology, specifically to a visual Gray bus line inspection device and method. Background Technology

[0002] Visualized Gray bus line tracking is a high-precision, visualized positioning technology solution widely used in industrial automation and other fields. The Gray bus positioning system operates based on Faraday's law of electromagnetic induction. An alternating current is passed through the coil in the electromagnetic transmitter to generate an alternating magnetic field. Under the action of this magnetic field, each pair of core wires of the Gray bus generates an induced electromotive force. The induced electromotive force is transmitted to the address reader through electromagnetic coupling. The reader determines the position of the mobile device by comparing the signal phase. Visualization is achieved by a camera capturing the image information of the target object. Then, image processing techniques, such as edge detection, feature matching, and template matching, are used to identify and locate the target object in the image, thereby determining the target object's position coordinates in the image.

[0003] In practical applications, Gray line busbars are typically laid along the running tracks of mobile equipment to accurately measure the equipment's position. Cameras are installed on the mobile equipment or at fixed locations to monitor the operating environment and the status of target objects. Both signals are fed into the computing and control system to control the moving equipment. For example, in an electric arc furnace charging crane, Gray line busbars are installed on the trolley and main trolley for position detection, along with panoramic cameras in the material pit and main hook recognition cameras, to achieve precise control of the crane's running position and visual monitoring of the unloading process. In a yard gantry crane system, Gray line busbars are used to position the trolley and main trolley, while cameras are installed at locations such as the gantry crane and loading lanes to monitor the loading and unloading of containers. The utility model disclosed in CN207457412U is a power line inspection trolley based on Hall sensors. A first motor is connected to the wheels and drives the wheels to rotate; a second motor is connected to the wheels through a transmission device and drives the wheels to turn; a first Hall sensor, a second Hall sensor, a third Hall sensor, the first motor and the second motor are electrically connected to a control device. By setting the above-mentioned device, the power line inspection trolley based on Hall sensors can effectively and accurately inspect the power line in underground wells and accurately detect the fault points of the power line.

[0004] The utility model with announcement number CN215415715U discloses a detection device for line maintenance. By setting up a movable arc rod and a fixed arc rod, when using a line inspection robot to inspect high-voltage lines, the movable arc rod and the fixed arc rod clamp the cable, thereby preventing the line inspection robot body from falling off the cable and ensuring that the line inspection robot body can be hung on the cable, thus improving the practicality of the line inspection robot body.

[0005] However, the cable inspection device disclosed above still has the following problems in actual use: it is adapted to the cable by clamping, but different specifications of cables cause deviations in the clamping force of the clamping mechanism. Large deformation can easily cause the inspection device to be too tight, thus affecting movement and inspection operations. At the same time, the surface of the cable that has been laid for a long time is covered with a lot of dust. If visual inspection is carried out without cleaning, misjudgment is likely to occur, reducing the accuracy and efficiency of cable inspection.

[0006] Therefore, we propose a visual Gray bus line inspection device and method to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a visual Gray bus line inspection device and method. This invention addresses the problem that existing methods use clamping to adapt to cables, but different cable specifications cause deviations in the clamping force of the clamping mechanism. Large deformations can easily lead to the inspection device being too tight, thus affecting movement and inspection operations. In addition, the surface of cables laid over a long period of time is covered with a large amount of dust, and visual inspection without cleaning can easily lead to misjudgments, reducing the accuracy and efficiency of line inspection.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a visual Gray busbar inspection device, comprising a detection bracket with a front and rear split structure, wherein the detection brackets are symmetrically arranged on the front and rear sides of the top of the Gray busbar body, and positioning columns are fixedly arranged at equal intervals on the bottom surface of the Gray busbar body; The detection bracket is provided with a line-following mechanism in the middle, and the line-following mechanism includes a line-following vision module. The line-following vision module is installed on the left and right sides of the middle of the detection bracket. At the same time, drive wheel sets are rotatably provided on the left and right sides of the inner end of the detection bracket. The line-following visual module is composed of visual probes that are distributed at equal intervals, and the distribution direction of the visual probes is opposite to the movement direction of the detection bracket. The detection bracket is provided with an adapter mechanism inside, and the adapter mechanism includes an adapter bracket. The adapter bracket has an adapter tube slidably sleeved on both the left and right sides of its inner end.

[0009] Preferably, the line inspection mechanism includes a line inspection visualization module fixedly installed at the lower end of the suitable pipes on the left and right sides, and the line inspection visualization module is slidably disposed on the top surface of the Gray bus body, and the length of the line inspection visualization module is greater than the width of the Gray bus body, so as to perform visual inspection of Gray bus bodies of different specifications.

[0010] Preferably, the adapter mechanism includes an adapter bracket fixedly installed in the middle of the top surface of the front and rear detection brackets, and the adapter bracket and the detection bracket are connected to each other through adapter tubes on the left and right sides. The top surface of the symmetrically arranged detection brackets is provided with a bidirectional screw rod, and the outer end thread of the bidirectional screw rod passes through the middle of the front and rear adapter brackets for adjusting the width of the split detection bracket.

[0011] Preferably, a positioning mechanism is provided below the detection bracket, and the positioning mechanism includes elastic sliding columns fixedly installed on the left and right sides of the bottom surface of the detection bracket. The bottom end of the elastic sliding column is fixedly connected to the outer end of the top surface of the positioning bracket. Furthermore, positioning wheel sets are rotatably provided on the left and right sides inside the positioning bracket through bearings, and the positioning wheel sets slide against the bottom surface of the Gray motherboard.

[0012] Preferably, the positioning mechanism includes a correction bracket fixedly installed in the middle of the elastic slide column, and a correction wheel set is rotatably arranged in the middle of the correction bracket via a bearing. The correction wheel set is rotatably arranged against the outer side wall of the Gray busbar body to assist in detecting the accuracy and stability of the detection bracket when it moves outside the Gray busbar body.

[0013] Preferably, the left end of the detection bracket is provided with a dust removal mechanism, and the dust removal mechanism includes a negative pressure dust removal box fixedly installed on the inner side of the left end of the detection bracket. The negative pressure dust removal box is rotatably provided with a diversion impeller fixedly connected to the shaft end of the drive wheel assembly. The right side of the negative pressure dust removal box has a unidirectional through-hole mesh storage box fixedly installed on the inner side of the left end of the detection bracket.

[0014] Preferably, the dust removal mechanism includes a drive shaft rotatably mounted below the left end of the detection bracket, and a dust removal brush roller is fixedly mounted in the middle of the drive shaft. A transmission shaft is rotatably arranged inside the left end of the detection bracket, and the upper end of the transmission shaft is meshed with the shaft of the drive wheel assembly through a first bevel gear set, while the lower end of the transmission shaft is meshed with the outer end of the drive shaft through a second bevel gear set. The outer wall of the drive shaft is connected to the upper and lower engagement strips of the inner ring of the second bevel gear group through the engagement grooves opened at the top and bottom. The outer side of the meshing second bevel gear group is fitted with a linkage frame to ensure that the second bevel gear groups on both sides are always in a meshing state.

[0015] Preferably, the dust removal mechanism includes a telescopic dust collection hopper fixedly installed below the left end of the front and rear detection brackets, and the middle part of the telescopic dust collection hopper is connected in a sliding sleeve manner. The top of the telescopic dust collection hopper is connected to the bottom end of the suction hose on both the front and rear sides. The top end of the suction hose is connected to the front end of the negative pressure dust collection box, which assists the dust removal brush roller in scraping the dust on the surface of the Gray motherboard and storing and collecting it through the negative pressure dust collection box and the screen storage box.

[0016] A method for a visual Gray busbar inspection device includes the following steps: S1: When installing the inspection bracket according to different specifications of the Gray busbar, the inspection bracket drives the positioning bracket connected by the elastic sliding column at the bottom to be sleeved on the outside of the Gray busbar. The inspection bracket is attached to the top surface of the Gray busbar through the internal drive wheel set. The correction bracket is attached to the front and rear outer walls of the inspection bracket through the middle correction wheel set, and the positioning wheel set inside the positioning bracket is attached to the bottom surface of the Gray busbar through the elastic sliding column, so as to avoid deviation during the line inspection. S2: By rotating the bidirectional lead screw above the detection bracket, the adapter bracket connected to the bidirectional lead screw is limited by the detection bracket, so as to drive the adapter brackets on the front and rear sides to move synchronously into the interior of the adapter tube, and drive the detection brackets on the front and rear sides to approach the Gray bus body to achieve clamping and positioning. The line inspection visual module installed below the adapter tube performs visual line inspection on the surface of the Gray bus body through the visual probe. S3: The detection bracket moves by rotating the inner drive wheel set. The drive wheel set drives the meshing transmission shaft to rotate through the first bevel gear set. The transmission shaft drives the drive shaft and the dust removal brush roller to rotate through the second bevel gear set. Thus, during the movement, the bracket is cleaned and dusted by adhering to the outer wall of the qualified lightning rod body. Furthermore, when the width of the symmetrically distributed detection bracket is changed for adaptation, it drives the transmission shaft and the second bevel gear group to move. The drive shaft is connected to the engagement crossbar of the inner ring of the second bevel gear group through the engagement cross groove on the outer wall, and the engagement state is ensured by the external linkage frame, so as to achieve continuous drive under the adaptation and adjustment of different needs. S4: The drive wheel assembly rotating inside the detection bracket drives the guide impeller inside the negative pressure dust collector box. The rotation of the guide impeller creates a negative pressure state. The negative pressure dust collector box and the screen storage box are connected in one direction, allowing the negative pressure dust collector box to draw air from the suction hose. The telescopic dust collection hopper, which is connected to the suction hose, is distributed on the top surface of the dust removal brush roller to draw in the scraped dust and move it with the airflow to the inside of the screen storage box. At the same time, the dust is blocked and the air is discharged through the sieving inside the screen storage box, thereby improving the accuracy of visual detection of the Gray motherboard body cleaning.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This visual Gray busbar inspection device and method moves by means of an inspection bracket adapted to the outside of the Gray busbar body. The dust removal mechanism is located in front of the travel direction and cleans the attached dust, and collects the dust by negative pressure. The visual probes arranged at the rear perform inspection of the cleaned Gray busbar body, thereby improving the accuracy and efficiency of visual inspection. The specific details are as follows: 1. The positioning bracket, which is connected to the elastic sliding column of the detection bracket, is sleeved on the outside of the Gray busbar body. The drive wheel set is attached to the top surface of the Gray busbar body, the positioning wheel set is attached to the bottom surface of the Gray busbar body, and the correction wheel set is attached to the side of the Gray busbar body to prevent deviation during line inspection.

[0018] Furthermore, the rotating bidirectional lead screw drives the threaded adapter bracket, which moves into the adapter tube after being limited by the detection bracket to ensure connectivity, and drives the detection bracket to slide inward synchronously to adapt to different specifications of Gray busbar bodies. At the same time, the drive wheel set rotates to drive the overall mechanism to move, and the visual probe inside the line inspection module performs visual inspection on the surface of the Gray busbar body.

[0019] 2. The drive wheel assembly drives the transmission shaft through the first bevel gear assembly, and the transmission shaft drives the drive shaft and the dust removal brush roller to rotate through the second bevel gear assembly. This allows the dust removal brush roller, which rotates in the opposite direction, to clean the surface of the Gray busbar during the line inspection process, preventing the attached dust from affecting the detection accuracy.

[0020] 3. The drive wheel assembly drives the impeller inside the negative pressure dust collector to rotate, drawing air through the through-connected suction hose. This creates a negative pressure inside the through-connected telescopic dust collection hopper, drawing in the dust from the surface of the corresponding dust removal brush roller. The dust is then carried by the airflow to the screen storage box for filtration, thereby improving the accuracy of visual inspection of the Gray motherboard. Attached Figure Description

The drive wheel group (15) drives the meshing transmission shaft (20) to rotate through the first bevel gear group (21). The transmission shaft (20) drives the drive shaft (18) and the dust removal brush roller (19) to rotate through the second bevel gear group (22). Thus, during the movement, the outer wall of the qualified lightning rod body (2) is cleaned and dusted. Furthermore, when the width of the symmetrically distributed detection bracket (1) is changed for adaptation, it drives the transmission shaft (20) and the second bevel gear group (22) to move. The drive shaft (18) is connected to the inner ring of the second bevel gear group (22) through the engagement groove on the outer wall, and the meshing state is guaranteed by the external linkage frame (23) so as to achieve continuous drive under the adaptation and adjustment of different needs. S4: The drive wheel assembly (15) rotating inside the detection bracket (1) drives the guide impeller (16) inside the negative pressure dust collector (14). The guide impeller (16) rotates to form a negative pressure state. The negative pressure dust collector (14) is unidirectionally connected to the screen storage box (17), so that the negative pressure dust collector (14) draws air from the suction hose (25) that is connected through. The telescopic dust collection hopper (24) connected through the suction hose (25) is correspondingly distributed on the top surface of the dust removal brush roller (19) so as to draw the scraped dust and move it with the airflow to the inside of the screen storage box (17). At the same time, the dust is blocked and the air is discharged through the screening inside the screen storage box (17), thereby cleaning the Gray motherboard body (2) and improving the accuracy of visual detection.
