Description

Technical Field

[0001] This utility model relates to the field of inspection robot technology, specifically a suspension device for a track inspection robot. Background Technology

[0002] Track inspection robots are intelligent inspection devices that move autonomously along tracks. They are specifically designed for inspecting equipment and facilities in industrial environments. The core structure of a track inspection robot includes a track system, a mobile platform, a sensor array, and an intelligent control system. It can operate continuously 24 hours a day via touch-sensitive power supply or battery drive. Application scenarios for track inspection robots cover power cable tunnels, chemical explosion-proof areas, steel metallurgical plants, rail transit, and data centers, replacing manual labor in high-risk environment inspections and reducing safety risks. Through the Internet of Things (IoT) and AI algorithms, track inspection robots can autonomously plan paths, avoid obstacles, and navigate, transmitting data to a monitoring platform in real time for anomaly warnings and fault diagnosis. With technological advancements, track inspection robots are developing towards greater autonomy and intelligence, becoming a key tool for ensuring safety and efficiency in the industrial sector.

[0003] The patent with publication number CN222244809U discloses a track inspection robot, including a robot that walks suspended on a track. The robot includes a shell, within which a walking mechanism and a camera mechanism are assembled and connected. The walking mechanism includes a suspended walking component, and the track inspection robot also includes a pull belt mechanism for pulling the camera mechanism, which is installed inside the shell. The pull belt mechanism includes a frame, within which a gear transmission component is assembled and connected, and a take-up pulley is assembled and connected to the gear transmission component. A pull belt is assembled and connected to the take-up pulley. The pull belt mechanism also includes a multi-stage telescopic cylinder and a belt cylinder fixedly assembled at the bottom of the frame. The lower end of the multi-stage telescopic cylinder is a telescopic part, which is fixedly connected to the camera mechanism. The pull belt passes through the belt cylinder and is fixed to the camera mechanism. The above device enables the robot to walk suspended on the track in a very flexible and stable manner, and during walking, it can flexibly and smoothly adjust the camera mechanism.

[0004] Although the above-mentioned device can flexibly adjust the camera mechanism while walking, it still has the following shortcomings: its core adjustment object is only the camera mechanism. The height of the camera is adjusted by the pull belt mechanism and multi-stage telescopic cylinder. However, this structure can only be adapted to a single camera. If environmental detection, such as temperature and humidity detection, dust concentration detection, or other inspection functions such as communication positioning and sound wave detection are required, the robot shell or pull structure needs to be significantly modified, resulting in poor compatibility and cumbersome operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a suspension device for a track inspection robot, which solves the problem of limited functional modules and inflexible expansion.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suspension device for a track inspection robot, comprising an inspection robot body that walks on a track, an electric telescopic rod that is fitted into the bottom surface of the inspection robot body, the telescopic end of the electric telescopic rod being set downward and the end being connected to a suspension base plate, an inspection camera being set in the middle of the bottom surface of the suspension base plate, sliding frames being set on the left and right sides of the bottom surface of the suspension base plate, an extension base plate being slidably installed on the sliding frames, the extension base plate being fixedly connected to the suspension base plate by mounting bolts set on the front and rear sides, and a functional expansion module being fixedly connected to the bottom surface of the extension base plate.

[0007] Furthermore, the bottom surface of the extended base plate has inverted U-shaped limiting grooves on the left and right sides. A compression spring is installed at the top of the inverted U-shaped limiting groove. A limiting plate that slides up and down is installed on the bottom surface of the inverted U-shaped limiting groove. A limiting block is installed on the bottom surface of the limiting plate. The bottom surface of the limiting block is lower than the bottom surface of the limiting plate. A limiting opening for accommodating the limiting block is opened on the bottom surface of the sliding frame. The limiting opening is installed vertically.

[0008] Furthermore, a magnetic clasp is provided in the middle of the top surface of the extended base plate, and a magnetic block that cooperates with the magnetic clasp is provided on the bottom surface of the suspended base plate.

[0009] Furthermore, telescopic distance measuring sensors are symmetrically installed on the left and right sides of the bottom surface of the inspection robot.

[0010] Furthermore, ground ranging sensors are symmetrically arranged on the left and right sides of the main body of the inspection robot.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By installing an electric telescopic rod, the height of the suspended base plate can be precisely adjusted to adapt to different equipment heights, blind spots, or obstacle environments under different tracks. With the cooperation of the sliding frame and the extended base plate, various functional modules such as environmental detection and communication positioning can be flexibly added or replaced without modifying the main structure. When the extended base plate slides, the limit block automatically engages with the limit slot under the action of spring force, achieving quick alignment before installation and reducing the time cost of manual adjustment. With the cooperation of magnetic plates and magnetic blocks, the extended base plate can be guided to automatically conform to the suspended base plate during sliding, reducing the difficulty of installation and improving assembly efficiency. By installing a telescopic distance sensor, the vertical distance between the inspection robot body and the suspended base plate can be detected and compared to determine if there is any problem with the electric telescopic rod's asynchronous extension and retraction. By installing a ground distance sensor, the vertical distance between the suspended base plate and the ground can be detected in real time, providing quantitative data for the height adjustment of the electric telescopic rod and ensuring accurate height adjustment.

[0014] 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.

[0015] like Figures 1 to 4 As shown, a suspension device for a track inspection robot includes a robot body 1 that walks on a track. An electric telescopic rod 2 is fitted onto the bottom surface of the robot body 1. The telescopic end of the electric telescopic rod 2 is set downward and connected to a suspension base plate 3 at its end. An inspection camera 4 is set in the middle of the bottom surface of the suspension base plate 3. Sliding frames 301 are set on the left and right sides of the bottom surface of the suspension base plate 3. An extension base plate 5 is slidably installed on the sliding frames 301. The extension base plate 5 and the suspension base plate 3 are fixedly connected by mounting bolts 302 set on the front and rear sides. A functional expansion module 6 is fixedly connected to the bottom surface of the extension base plate 5.

[0016] like Figure 1 As shown, the inspection robot in this utility model has a similar structure to existing inspection robots. For example, patent CN222244809U discloses a track inspection robot. The main improvement of this utility model is that it solves the problem of limited functional modules and inflexible expansion. Figures 1 to 4As shown, the suspension device for a track inspection robot in this utility model allows for the selection of appropriate functional expansion modules 6 before use, such as temperature and humidity detection modules, dust concentration detection modules, communication and positioning modules, and sound wave detection modules, according to the needs of the scenario. Then, the front end of the expansion base plate 5 is slid into the sliding frame 301. At this time, the operator manually presses the limiting block 504 upwards, and the entire expansion base plate 5 can smoothly slide into the sliding frame 301. When the limiting block 504 reaches the limiting port 303, the elastic force of the compression spring 502 is released, the limiting block 504 falls and is locked into the limiting port 303, and the expansion base plate 5 is initially fixed. Subsequently, with the cooperation of the magnetic suction plate 505, the magnetic suction block 304, and the mounting bolt 302, the expansion base plate 5 is firmly fixed to the bottom surface of the suspension base plate 3, realizing the functional expansion of the inspection robot body 1.

[0017] like Figure 3 and Figure 4 As shown, the bottom surface of the extended base plate 5 has inverted U-shaped limiting grooves 501 on the left and right sides. A compression spring 502 is provided at the top of the inverted U-shaped limiting groove 501. A sliding limiting plate 503 is provided on the bottom surface of the inner side of the inverted U-shaped limiting groove 501. A limiting block 504 is provided on the bottom surface of the limiting plate 503. The bottom surface of the limiting block 504 is lower than the bottom surface of the limiting plate 503. A limiting opening 303 for accommodating the limiting block 504 is provided on the bottom surface of the sliding frame 301. The limiting opening 303 is provided vertically.

[0018] Specifically, during the installation of the extension base plate 5, as the extension base plate 5 slides inward on the sliding frame 301, the operator manually presses the limiting block 504 upward. With the compression of the compression spring 502, the bottom surface of the pressing limiting block 504 fits against the inner side of the sliding frame 301, allowing the extension base plate 5 to slide smoothly into the sliding frame 301. When the limiting block 504 reaches the limiting opening 303, the elastic force of the compression spring 502 is released, and the limiting block 504 falls and engages in the limiting opening 303, initially fixing the extension base plate 5. This achieves quick alignment before installation, reducing the time cost of manual adjustment. When it is necessary to remove the extension base plate 5, the limiting opening 303, which runs vertically through the plate, is used to push the limiting block 504 upward, allowing the extension base plate 5 to be removed. The operation is simple and convenient.

[0019] like Figure 2 and Figure 4 As shown, a magnetic absorbing piece 505 is provided in the middle of the top surface of the extended base plate 5, and a magnetic absorbing block 304 that cooperates with the magnetic absorbing piece 505 is provided on the bottom surface of the suspended base plate 3.

[0020] Specifically, with the cooperation of the magnetic clasp 505 and the magnetic block 304, the extended base plate 5 can be guided to automatically fit against the suspended base plate 3 during the sliding process, reducing the difficulty of installation and improving assembly efficiency.

[0021] like Figure 2 As shown, telescopic distance sensors 101 are symmetrically arranged on the left and right sides of the bottom surface of the main body 1 of the inspection robot.

[0022] Specifically, by symmetrically arranging telescopic distance sensors 101 on the left and right sides of the bottom surface of the inspection robot body 1, the vertical distance between the inspection robot body 1 and the suspended base plate 3 can be detected in real time during the up and down movement of the suspended base plate 3. This provides quantitative data for the height adjustment of the electric telescopic rod 2, ensuring accurate height adjustment. At the same time, the two telescopic distance sensors 101 symmetrically arranged on the left and right sides can compare with each other to determine whether there is a problem of asynchronous extension and retraction of the electric telescopic rod 2. If a deviation is found, the control system can adjust the movement of the electric telescopic rod 2 in a timely manner to ensure that the suspended base plate 3 always remains horizontal, avoiding equipment damage or data distortion caused by tilting.

[0023] like Figure 1 and Figure 2 As shown, ground distance sensors 102 are symmetrically arranged on the left and right sides of the suspension base plate 3.

[0024] Specifically, by symmetrically setting ground distance sensors 102 on the left and right sides of the suspension base plate 3, the vertical distance between the suspension base plate 3 and the ground can be detected in real time during the up and down movement of the suspension base plate 3. The data is then compared with the data transmitted by the telescopic distance sensor 101 to further improve the adjustment accuracy.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
