Description

Technical Field

[0001] This utility model relates to the field of inspection robot technology, specifically a suspended inspection robot capable of handling track dust. Background Technology

[0002] A suspended inspection robot is a robot specifically designed to operate suspended above a specific track or cable and perform automated inspection tasks. It is typically fixed to the track by a robust robotic arm or hanger, with its main body "suspended" below the track, operating stably under the influence of gravity, while using cameras, sensors, and other equipment to monitor the equipment and environment below or around it.

[0003] Patent CN221756049U discloses a suspended inspection robot, including a moving mechanism, a lifting mechanism, a control mechanism, and a detection mechanism. The moving mechanism has a connecting opening at one end along a first direction, which extends through the moving mechanism in a second direction, and a moving wheel is installed within the connecting opening. The lifting mechanism is positioned along the first direction and connected to the end of the moving mechanism away from the connecting opening. The lifting mechanism is retractable along the first direction, and the end of the lifting mechanism away from the moving mechanism along the first direction is connected to the control mechanism. The detection mechanism is located at the end of the control mechanism away from the lifting mechanism along the first direction and is used to inspect the equipment to be inspected. The control mechanism is electrically connected to the moving mechanism, the lifting mechanism, and the detection mechanism, controlling the suspended inspection robot to move along a guide rail, controlling the lifting mechanism to rise and fall, and controlling the detection mechanism to track and acquire image information of the equipment to be inspected.

[0004] However, the aforementioned inspection robots still present the following problems in actual use: Some suspended inspection robots are often deployed in dusty environments, such as industrial plants or construction sites. In these scenarios, dust easily accumulates on the track surface. Dust accumulation not only causes unevenness on the track surface, leading to vibrations, jamming, or abnormal noises during robot operation, but more importantly, the hard particles can act like sandpaper, repeatedly rubbing against the robot's wheels or guide wheels and the track, exacerbating mechanical wear and shortening the lifespan of key components and even the entire machine. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a suspended inspection robot that can handle track dust, which can suck up the dust on the moving route and reduce the probability of wheel wear.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a suspended inspection robot capable of handling track dust, comprising a robot body mounted on a hanging rail, an electric telescopic rod mounted on the bottom of the robot body, and a camera mounted on the other end of the electric telescopic rod. Suction pipes are fixedly connected to the four corners of the robot body. Each of the four suction pipes has a No. 1 port and a No. 2 port extending through it at the end closest to the hanging rail. The No. 1 port is located at the end of the suction pipe, and the No. 2 port is located at the bottom of the suction pipe. A bladeless fan is fixedly connected to the inner wall of each suction pipe. Two suction pipes at the same end of the robot body, away from the No. 1 port, are connected to a dust collection assembly. The other ends of the two dust collection assemblies are connected to a support assembly. The middle of the support assembly is connected to the electric telescopic rod. The two ends of the bladeless fan face the No. 1 port and the dust collection assembly, respectively.

[0007] Furthermore, the support assembly includes a support plate, two positioning plates, and two knobs. The middle part of the support plate is fixedly connected to the end of the electric telescopic rod near the camera. Both sides of the upper surface of the support plate are fixedly connected to the two positioning plates. The two ends of the support plate are respectively connected to two dust collection components, and the two dust collection components abut against the two positioning plates. The threaded rods of the two knobs are respectively threaded to the two ends of the support plate, and the threaded rods of the two knobs are also respectively connected to the two dust collection components.

[0008] Furthermore, the dust collection assembly includes a dust collection screen and two bellows tubes. The upper ends of the two bellows tubes are fixedly connected to the ends of two suction pipes on the same end of the robot body, which are far apart from each other. The other ends of the two bellows tubes are threaded to the two sides of the upper end of the dust collection screen. The lower end of the dust collection screen is connected to the support plate, and the side wall of the lower end of the dust collection screen abuts against the positioning plate. The end of the knob that passes through the support plate is threaded to the bottom surface of the dust collection screen. The end of the bladeless fan that is far away from the No. 1 port faces the bellows tube.

[0009] Furthermore, several T-shaped rails are fixedly connected to the upper surfaces of both ends of the support plate, and several T-shaped grooves are opened on the bottom surface of the dust collection screen cylinder. The several T-shaped rails are slidably connected to the several T-shaped grooves respectively.

[0010] Furthermore, the total height of the dust collection screen and the support plate shall not exceed the minimum shortening length of the electric telescopic rod.

[0011] Furthermore, the dust collection screen is a rigid straight cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This type of suspended inspection robot, which can handle track dust, has a suction pipe with No. 1 (end) and No. 2 (bottom) at the four corners of the robot body. Combined with the negative pressure generated by the fan blades driven by the internal motor, it can simultaneously adsorb dust on the sides and bottom of the suspended track (especially the track area in front of the robot's movement direction), effectively removing accumulated dust and hard particles. This avoids friction between the moving wheels and "sandpaper-like" particles, reduces wear and tear on mechanical parts, and extends the service life of key components such as the robot's walking wheels and guide wheels. 2. This type of suspended inspection robot that can handle track dust has a dust collection screen connected to a suction pipe via a bellows pipe. After the dust enters the dust collection screen through the suction pipe and the bellows pipe, the air is discharged through the mesh, achieving air-dust separation. The dust collection screen adopts a rigid straight cylinder structure to avoid collapse and ensure long-term stable dust collection. 3. This type of suspended inspection robot, which can handle track dust, has a support component linked to an electric telescopic rod. During maintenance, the support plate and dust collection component can be lowered to ground level via the electric telescopic rod. With the knob threaded connection and the T-shaped rail and T-slot sliding structure, the dust collection screen can be quickly disassembled without climbing, making cleaning or replacement convenient and reducing maintenance difficulty and safety risks.

[0015] 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.

[0016] Please see Figures 1-5A suspended inspection robot capable of handling track dust includes a robot body 1 mounted on a hanging rail, an electric telescopic rod 2 mounted on the bottom of the robot body 1, and a camera 3 mounted on the other end of the electric telescopic rod 2. Four suction pipes 4 are fixedly connected to the four corners of the robot body 1. Each of the four suction pipes 4 has a first port 401 and a second port 402 extending through it near the hanging rail. The first port 401 is located at the end of the suction pipe 4, and the second port 402 is located at the bottom of the suction pipe 4. A bladeless fan 10 is fixedly connected to the inner wall of the suction pipe 4. Two suction pipes 4 at the same end of the robot body 1, away from the first port 401, are connected to a dust collection assembly. The other ends of the two dust collection assemblies are connected to a support assembly. The middle of the support assembly is connected to the electric telescopic rod 2. The two ends of the bladeless fan 10 face the first port 401 and the dust collection assembly, respectively.

[0017] like Figures 1 to 5 As shown, in use, the suspended inspection robot capable of handling track dust in this utility model, while the robot body 1 is moved by several moving wheels, the bladeless fans 10 inside the four suction pipes 4 are also activated. As the robot body 1 moves along the suspended rail, the two bladeless fans 10 generate negative pressure suction inside the suction pipes 4, thereby adsorbing the dust on the suspended rail through port 1 401 and port 2 402 (adsorption positions are as follows). Figure 1 As shown in the figure, this can reduce the friction between the moving wheels of the robot body 1 and the dust, and improve the service life of the moving wheels; In addition, the bladeless fan 10 will draw in the dust and collect it into the dust collection component through the suction pipe 4. When the task is completed or during regular maintenance, the electric telescopic rod 2 will be activated to control the dust collection component and the support component to descend. The dust collection component can be removed from the support component while standing on the ground, so as to clean the dust inside the dust collection component or replace it with a new dust collection component. It is important to note here that: The robot body 1, the electric telescopic rod 2, and the camera 3 are all conventional technologies in existing suspended inspection robots. In this utility model, only the disclosed structure is partially improved. Structures not mentioned, such as the moving wheels of the robot body 1, the telescopic method of the electric telescopic rod 2, and the shooting and rotation method of the camera 3, are not modified in any way and retain their original functions and effects. The bladeless fan 10 works by drawing in and pressurizing air through a centrifugal compressor in the base. It utilizes the Coanda effect (the phenomenon of air flowing along curved surfaces) and the Bernoulli effect (the relationship between velocity and pressure) to multiply the airflow. When the high-speed airflow is ejected from the annular nozzle, the surrounding air is drawn in, forming a continuous and stable airflow. In addition, the bladeless fan 10 is a mature existing technology, which typically includes, but is not limited to: a base (main unit) that houses the motor, impeller and circuit system; a centrifugal compressor that pressurizes air by high-speed rotation of the impeller to increase airflow speed and flow; an annular nozzle that guides the pressurized air out at high speed and adsorbs surrounding air through the Coanda effect to form a multiplier airflow; an air inlet located at the bottom or side of the base that draws in ambient air as an air source; and an air outlet (annular structure) that ejects high-speed airflow to form the final blow, etc. Furthermore, since the bladeless fan 10 is located inside the suction pipe 4, some bladeless fans 10 with good dustproof effect can be selected, and the specific model is not limited.

[0018] As a preferred embodiment of this utility model, the support assembly includes a support plate 6, two positioning plates 7, and two knobs 9. The middle part of the support plate 6 is fixedly connected to the end of the electric telescopic rod 2 near the camera 3. Both sides of the upper surface of the support plate 6 are fixedly connected to the two positioning plates 7. The two ends of the support plate 6 are respectively connected to two dust collection components, and the two dust collection components abut against the two positioning plates 7 respectively. The threaded rods of the two knobs 9 are respectively threadedly connected to the two ends of the support plate 6, and the threaded rods of the two knobs 9 are also respectively connected to the two dust collection components.

[0019] More specifically, by setting up support components, the dust collection components can be supported during routine inspections to ensure that they do not separate from the electric telescopic rod 2; and when it is necessary to process the dust inside the dust collection components, the dust collection components can be removed from the support plate 6 and the positioning plate 7 by loosening the knob 9. In addition, during installation, first place the bottom of the dust collection component on the support plate 6, then place one side of the lower end of the dust collection component against the positioning plate 7, and then turn the knob 9 to fix the dust collection component to the support plate 6.

[0020] As a preferred embodiment of this utility model, the dust collection assembly includes a dust collection cylinder 5 and two bellows tubes 8. The upper ends of the two bellows tubes 8 are fixedly connected to the ends of the two suction pipes 4 on the same end of the robot body 1, which are far apart from each other. The other ends of the two bellows tubes 8 are threadedly connected to the two sides of the upper end of the dust collection cylinder 5. The lower end of the dust collection cylinder 5 is connected to the support plate 6, and the side wall of the lower end of the dust collection cylinder 5 abuts against the positioning plate 7. The knob 9 passes through the support plate 6 and is threadedly connected to the bottom surface of the dust collection cylinder 5. The end of the bladeless fan 10 away from the first port 401 faces the bellows tube 8.

[0021] More specifically, when the bladeless fan 10 starts, it draws dust into the inside of the bellows tube 8, and the dust enters the dust collection screen 5 through the bellows tube 8. Then, clean air is discharged from the mesh of the dust collection screen 5 into the external environment. When it is necessary to clean the dust inside the dust collection cylinder 5, simply activate the electric telescopic rod 2. The electric telescopic rod 2 controls the support plate 6 to descend to a height that maintenance personnel can operate at. Then, the operator turns the knob 9, and the knob 9 gradually loosens from the dust collection cylinder 5. At this point, the dust collection cylinder 5 can be removed from the support plate 6. In addition, because the bellows pipe 8 is threadedly connected to the dust collection cylinder 5, after removing the dust collection cylinder 5, simply turn the bellows pipe 8 again to separate the bellows pipe 8 from the dust collection cylinder 5, and the inside of the support plate 6 can be cleaned.

[0022] As a preferred embodiment of this utility model, several T-shaped rails 11 are fixedly connected to the upper surfaces of both ends of the support plate 6, and several T-shaped grooves 501 are opened on the bottom surface of the dust collection cylinder 5. The several T-shaped rails 11 are slidably connected to the several T-shaped grooves 501 respectively.

[0023] More specifically, by setting the T-shaped rail 11 and the T-shaped groove 501, the connection between the dust collection screen cylinder 5 and the support plate 6 can be further restricted, while improving the stability of the dust collection screen cylinder 5 on the support plate 6. It should be noted that the sliding connection between the T-rail 11 and the T-slot 501 has a large friction. If the knob 9 comes loose during the inspection, causing the dust collection screen 5 to separate from the support plate 6, there will be additional force to reduce the probability that the dust collection screen 5 will fall directly. Alternatively, a photoelectric sensor can be installed at the point where the dust collection cylinder 5 and the support plate 6 meet. If the photoelectric sensor detects the dust collection cylinder 5 and the support plate 6, an alarm can be issued in time, and the robot body 1 will stop moving and wait for maintenance personnel to lock the dust collection cylinder 5 and the support plate 6 again.

[0024] As a preferred embodiment of this utility model, the total height of the dust collection cylinder 5 and the support plate 6 is not greater than the minimum shortening length of the electric telescopic rod 2.

[0025] More specifically, this design can prevent the dust collection cylinder 5 and the support plate 6 from colliding with the robot body 1 when the electric telescopic rod 2 is retracted to its minimum state.

[0026] As a preferred embodiment of this utility model, the dust collection screen cylinder 5 is a rigid straight cylinder.

[0027] More specifically, by setting the dust collection cylinder 5 as a rigid cylinder, the rigidity of the dust collection cylinder 5 can be guaranteed, preventing the dust collection cylinder 5 from collapsing and affecting the dust collection or the detection of the robot body 1.

[0028] 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.
