Description

Technical Field

[0001] This utility model relates to the field of robot inspection technology, and in particular to a belt conveyor inspection and fire protection system. Background Technology

[0002] Belt conveyors, as an ideal and efficient transportation device, have advantages such as long conveying distance, large capacity, and continuous conveying. Especially in the coal mining industry, belt conveyors serve as an important transportation channel connecting coal mines and pithead power plants, featuring large transport capacity, simple structure, energy saving, emission reduction, and environmental friendliness. However, their disadvantages are also quite obvious. The bearings of the idler rollers of belt conveyors are prone to overheating during prolonged operation, potentially causing fires. To ensure the safe operation of belt conveyors, daily inspections are necessary.

[0003] Currently, routine inspections of belt conveyors are mostly conducted manually. Inspectors conduct inspections every 2-4 hours, carrying temperature guns, vibration meters, logbooks, etc., relying on their observation to complete the daily inspection work. However, inspectors are prone to missing items during the inspection process, and due to the long inspection cycle, they cannot conduct timely inspections, resulting in low inspection efficiency. Even if inspectors discover situations such as fires, they may not be able to take effective measures in a timely manner, posing significant safety hazards. Utility Model Content

[0004] The main purpose of this utility model is to propose a belt conveyor inspection and fire protection system, which aims to solve the technical problems of low efficiency and significant safety hazards associated with manual inspection.

[0005] To achieve the above objectives, this utility model proposes a belt conveyor inspection and fire protection system, comprising:

[0006] Location base station;

[0007] A hanging rail is provided on one side of the belt conveyor along its extension direction, and the extension direction of the hanging rail is the same as the extension direction of the belt conveyor.

[0008] The inspection robot has a first mobile cabin and a detection camera and a first positioning tag mounted on the mobile cabin. The first mobile cabin is movably mounted on the rail. The conveyor belt of the belt conveyor surrounds and forms an observation area. The idler roller of the belt conveyor is located in the observation area. The detection camera faces the observation area and is used to collect the scene of the observation area. The first positioning tag is connected to the positioning base station signal to locate the position of the inspection robot.

[0009] The fire-fighting robot is signal-connected to the inspection robot. The fire-fighting robot has a second mobile cabin and a fire extinguishing device and a second positioning tag installed on the second mobile cabin. The second mobile cabin is movably mounted on the rail. The second positioning tag is signal-connected to the positioning base station to locate the position of the fire-fighting robot.

[0010] In one embodiment, two rails are provided, which are respectively provided on both sides of the belt conveyor along its extension direction, and at least one inspection robot and at least one fire-fighting robot are suspended on each rail;

[0011] Both the top of the first mobile cabin and the top of the second mobile cabin are provided with a traveling mechanism, and the traveling mechanism is movably mounted on the hanging rail. The traveling mechanism can move along the hanging rail and drive the corresponding first mobile cabin or second mobile cabin to move along the hanging rail.

[0012] In one embodiment, the top of both the first mobile cabin and the top of the second mobile cabin are provided with two traveling mechanisms that are sequentially distributed along the extension direction of the hanging rail.

[0013] In one embodiment, the traveling mechanism includes a drive member, two mounting plates and two first traveling wheels. The two mounting plates are horizontally spaced apart on the top of the corresponding first mobile cabin or the top of the second mobile cabin. The two first traveling wheels are respectively disposed on the opposite side of the two mounting plates, and there is a gap between the two first traveling wheels.

[0014] The hanging rail extends horizontally to both sides to form two corresponding slide rails. The two first traveling wheels are rotatably supported on the top of the two slide rails. The driving member is used to drive the two first traveling wheels to rotate, so as to drive the corresponding first mobile cabin or second mobile cabin to move along the hanging rail.

[0015] In one embodiment, the traveling mechanism further includes a second traveling wheel, the two ends of which are respectively connected to the two mounting plates along the horizontal direction and are located below the two first traveling wheels. The second traveling wheel and the two first traveling wheels are respectively provided with two limiting gaps. The two slide rails are respectively limited within the two limiting gaps, and the second traveling wheel rollably abuts against the bottom of each slide rail.

[0016] In one embodiment, each of the mounting plates is further provided with a support frame, and the support frame is provided with a follower wheel, which can roll against the side of one of the slide rails opposite to the other slide rail.

[0017] In one embodiment, a charging position is provided on the hanging rail, and the belt conveyor inspection and fire protection system further includes a charging pile, which is provided corresponding to the charging position;

[0018] Both the interior of the first mobile cabin and the interior of the second mobile cabin are equipped with power sources. Both the top of the first mobile cabin and the top of the second mobile cabin are equipped with lifting drive components. The top of each lifting drive component is equipped with a charging connector that is electrically connected to the power source.

[0019] The lifting drive is used to drive the charging connector to rise and fall when the corresponding first or second mobile cabin moves along the rail to the charging position, so that the charging connector is electrically connected or disconnected from the charging pile.

[0020] In one embodiment, the first mobile cabin is also equipped with a microphone for collecting sound.

[0021] In one embodiment, both the first and second mobile cabins are equipped with infrared cameras for detecting the bearing temperature of the idler rollers.

[0022] In one embodiment, a servo motor is provided at the bottom of the second mobile cabin, and the nozzle of the fire extinguishing device is mounted on the servo motor. The servo motor can rotate to adjust the orientation of the nozzle.

[0023] This utility model's inspection and fire-fighting system, by employing an inspection robot to replace manual inspections, enables 24 / 7 uninterrupted inspections, unaffected by time or weather conditions, significantly improving inspection efficiency. Simultaneously, the inspection robot can automatically inspect along a preset path, ensuring that every key point is checked, avoiding potential omissions during manual inspections. The inspection robot's detection camera continuously collects images of the conveyor belt's operating status. Through image analysis technology, it can promptly detect anomalies such as belt misalignment, damaged idlers, idler falls, or fires, providing early warnings and helping to prevent malfunctions. Once the inspection robot detects anomalies such as belt misalignment, damaged idlers, or fallen idlers, it can alarm to remind workers to replace them. In the event of an emergency such as a fire, it can immediately notify a fire-fighting robot to proceed to the scene. Compared to manual labor, the fire-fighting robot's fire extinguishing device can be activated quickly, effectively controlling the fire in a timely manner, reducing losses, and eliminating safety hazards. In summary, the inspection robot reduces reliance on manual inspections, lowers the labor intensity caused by frequent manual inspections, and also reduces labor costs. Attached Figure Description

[0036] As an ideal and efficient transportation equipment, belt conveyors have advantages such as long conveying distance, large carrying capacity, and continuous conveying. Especially in the coal mining industry, belt conveyors serve as an important transportation channel connecting coal mines and pithead power plants, featuring large carrying capacity, simple structure, energy saving and emission reduction, and green environmental protection. However, their disadvantages are also quite obvious. The bearings of belt conveyor idlers are prone to overheating over time, which may cause fires. To ensure the safe operation of belt conveyors, daily management of belt conveyors is necessary.

[0037] Currently, the daily management of belt conveyors is mostly done through manual inspections. Inspectors conduct inspections every 2-4 hours, carrying temperature guns, vibration meters, logbooks, etc., relying on their eyes and ears to complete the daily inspection work. However, inspectors are prone to missing inspections during the inspection process, and due to the long inspection cycle, they cannot conduct timely inspections, resulting in low inspection efficiency. Even if inspectors discover situations such as fires, they may not be able to take effective measures in a timely manner.

[0038] This utility model proposes a belt conveyor 200 inspection and fire protection system 100.

[0039] Please see Figures 1-4In one embodiment of this utility model, the inspection and fire-fighting system 100 includes a positioning base station 1, a hanging rail 4, an inspection robot 2, and a fire-fighting robot 3. The hanging rail 4 is disposed on one side of the belt conveyor 200 along its extension direction, and the extension direction of the hanging rail 4 is the same as the extension direction of the belt conveyor 200. The inspection robot 2 has a first mobile cabin 21 and a detection camera 22 and a first positioning tag 23 disposed on the mobile cabin. The first mobile cabin 21 is movably hung on the hanging rail 4, and the conveyor belt 201 of the belt conveyor 200 surrounds it to form an observation area. The idler roller 202 of the conveyor 200 is located in the observation area. The detection camera 22 faces the observation area and is used to collect the scene of the observation area. The first positioning tag 23 is signal-connected to the positioning base station 1 to locate the position of the inspection robot 2. The inspection robot 2 is signal-connected to the fire-fighting robot 3. The fire-fighting robot 3 has a second mobile cabin 31 and a fire extinguishing device 33 and a first positioning tag 32 installed on the second mobile cabin 31. The second mobile cabin 31 is movably hung on the hanging rail 4. The first positioning tag 32 is signal-connected to the positioning base station 1 to locate the position of the fire-fighting robot 3.

[0040] The inspection and fire protection system 100 of this utility model, by using an inspection robot 2 to replace manual inspection, can achieve uninterrupted inspection 24 hours a day, without being limited by time and weather conditions, significantly improving inspection efficiency. The rail 4 enables the inspection robot 2 and the fire protection robot 3 to move stably on the route formed by the rail 4, avoiding the influence of uneven ground or other obstacles on the movement of the robots, ensuring the movement accuracy and stability of the inspection robot 2 and the fire protection robot 3, especially in long-distance or complex environment inspection tasks. Through the layout of the rail 4, the inspection robot 2 and the fire protection robot 3 can easily cover the entire length of the belt conveyor 200, greatly expanding the working range of the inspection robot 2 and the fire protection robot 3, and the rail 4 does not occupy ground space. Meanwhile, the inspection robot 2 can automatically inspect along the route of the track 4, ensuring that each idler roller in the observation area is captured by the detection camera, avoiding missed inspections that may occur during manual inspection. Furthermore, because the detection camera 22 equipped on the inspection robot 2 can continuously collect images of the observation area, it can detect anomalies such as belt misalignment, damaged idler roller 202, fallen idler roller 202, or fires, enabling early warning and helping to prevent malfunctions. Once the inspection robot 2 detects an emergency such as a fire, it can promptly send a signal to the fire-fighting robot 3 to handle the situation. Compared to manual inspection, the fire-fighting robot 3 is equipped with a fire extinguishing device 33 that can be activated immediately, effectively controlling the fire, reducing losses, and eliminating safety hazards. In summary, the inspection robot 2 reduces reliance on manual inspection, lowers the labor intensity caused by frequent manual inspections, and also reduces labor costs.

[0041] Both the inspection robot 2 and the firefighting robot 3 are equipped with the first positioning tag 23 and the first positioning tag 32, respectively, and both maintain a signal connection with the positioning base station 1. This enables the inspection robot 2 and the firefighting robot 3 to accurately determine their own positions in complex working environments and achieve precise navigation. In addition, the collaborative work of the inspection robot 2 and the firefighting robot 3 also improves the efficiency and accuracy of fire emergency response.

[0042] It should be noted that the signal interaction method between the inspection robot 2 and the firefighting robot 3, as well as the technology for image analysis, can all utilize existing technologies.

[0043] like Figure 1 As shown, the belt conveyor 200 extends in the front-to-back direction.

[0044] In one embodiment, two rails 4 are provided, and the two rails 4 are respectively provided on both sides of the belt conveyor 200 along its extension direction. At least one inspection robot 2 and at least one fire-fighting robot 3 are suspended on each rail 4.

[0045] The top of the first mobile cabin 21 and the top of the second mobile cabin 31 are both provided with a traveling mechanism 5, and the traveling mechanism 5 is movably hung on the hanging rail 4. The traveling mechanism 5 can move along the hanging rail 4 and drive the corresponding first mobile cabin 21 or second mobile cabin 31 to move along the hanging rail 4.

[0046] Understandably, by setting rails 4 on both sides of the belt conveyor 200, and installing inspection robots 2 and fire-fighting robots 3 on each rail 4, abnormal conditions of the belt conveyor 200 can be better observed, facilitating timely detection and resolution of abnormalities to reduce losses. The traveling mechanism 5 is directly mounted on the rails 4, and can quickly adjust the positions of the inspection robots 2 and fire-fighting robots 3 as needed. Whether for inspection or fire emergency handling, they can quickly reach the designated position along the rails 4, improving the overall system response speed.

[0047] Among them, the two hanging rails 4 are independent of each other and not connected to each other, and the inspection robot 2 and the fire-fighting robot 3 on them can operate independently without interfering with each other.

[0048] In one embodiment, the top of the first mobile cabin 21 and the top of the second mobile cabin 31 are each provided with two traveling mechanisms 5 distributed sequentially along the extension direction of the hanging rail 4.

[0049] Understandably, by setting up two travel mechanisms 5, the weight of the inspection robot 2 or the fire-fighting robot 3 can be better distributed, making it more stable on the track 4, especially when turning or going up or down slopes, which can effectively prevent tipping or imbalance; when one travel mechanism 5 fails, the other travel mechanism 5 can still continue to work, ensuring that the inspection robot 2 and the fire-fighting robot 3 will not stop operating due to the failure of a single component, thus improving reliability and availability.

[0050] In one embodiment, the traveling mechanism 5 includes a drive member, two mounting plates 51, and two first traveling wheels 52. The two mounting plates 51 are horizontally spaced on the top of the corresponding first moving cabin 21 or the top of the corresponding second moving cabin 31. The two first traveling wheels 52 are respectively disposed on the opposite side of the two mounting plates 51, and there is a gap between the two first traveling wheels 52. The hanging rail 4 extends horizontally to both sides to form two corresponding slide rails 41. The two first traveling wheels 52 are rotatably supported on the top of the two slide rails 41. The drive member is used to drive the two first traveling wheels 52 to rotate, so as to drive the corresponding first moving cabin 21 or the second moving cabin 31 to move along the hanging rail 4.

[0051] Understandably, the two first traveling wheels 52 are supported on the two slide rails 41 respectively, forming a stable double-wheel support structure, which effectively prevents the robot from tipping over or swaying during movement; the gap between the two first traveling wheels 52 can accommodate the slight deformation or unevenness of the hanging rail 4, ensuring that the traveling wheels always maintain good contact with the slide rail 41, thus improving the overall stability; the cooperation between the two slide rails 41 and the two first traveling wheels 52 can provide precise guidance, ensuring that the inspection robot 2 and the fire-fighting robot 3 move stably along the predetermined path on the hanging rail 4, thus improving the positional accuracy; when the drive unit drives the first traveling wheel 52 to rotate, it moves on the slide rail 41, thereby driving the corresponding inspection robot 2 and fire-fighting robot 3 to move along the hanging rail 4.

[0052] Specifically, the two travel wheels can be equipped with an independent emergency braking system, which can immediately stop the robot's movement and ensure safety once an abnormality is detected.

[0053] Specifically, the drive component can be a drive motor from the existing technology; the two mounting plates 51 can be metal plates, which have better structural stability and are suitable for long-term use.

[0054] In one embodiment, the traveling mechanism 5 further includes a second traveling wheel 53, the two ends of which are connected to two mounting plates 51 in the horizontal direction and are located below the two first traveling wheels 52. The second traveling wheel 53 and the two first traveling wheels 52 have two limiting gaps respectively. The two slide rails 41 are respectively limited within the two limiting gaps, and the second traveling wheel 53 rollably abuts against the bottom of each slide rail 41.

[0055] Understandably, the second traveling wheel 53 is located below the two first traveling wheels 52 and contacts the bottom of the slide rail 41. The first traveling wheels 52 and the second traveling wheels 53 cooperate with the upper and lower surfaces of the slide rail 41, which can effectively prevent the inspection robot 2 and the fire-fighting robot 3 from swaying in the vertical direction, ensuring that the inspection robot 2 and the fire-fighting robot 3 are more stable on the hanging rail 4; and can provide more precise guidance, ensuring that the inspection robot 2 and the fire-fighting robot 3 move accurately along the predetermined path on the hanging rail 4, thus improving the positional accuracy.

[0056] In one specific embodiment, the second traveling wheel 53 can also be driven by a drive motor to rotate.

[0057] In one embodiment, each mounting plate 51 is further provided with a support frame 54, and the support frame 54 is provided with a follower wheel 55, which can roll against the side of one slide rail 41 away from the other slide rail 41.

[0058] Understandably, the contact between the follower wheel 55 and the side of the slide rail 41 opposite to the other slide rail 41 can effectively prevent the robot from swaying and deviating laterally, ensuring that the inspection robot 2 and the fire-fighting robot 3 remain stable during movement. This allows the three surfaces of the slide rail 41 to cooperate with the second traveling wheel 53, the corresponding first traveling wheel 52, and the follower wheel 55, respectively, reducing friction and energy loss, and making the inspection robot 2 and the fire-fighting robot 3 move more smoothly on the rail 4.

[0059] In one embodiment, a charging position is provided on the hanging rail 4, and the belt conveyor 200 inspection fire protection system 100 also includes a charging pile, with the charging pile corresponding to the charging position; a power supply is provided inside the first mobile cabin 21 and the second mobile cabin 31, and a lifting drive 6 is provided on the top of the first mobile cabin 21 and the top of the second mobile cabin 31, with a charging connector 7 electrically connected to the power supply at the top of each lifting drive 6; the lifting drive 6 is used to drive the charging connector 7 to rise and fall when the corresponding first mobile cabin 21 or second mobile cabin 31 moves along the hanging rail 4 to the charging position, so that the charging connector 7 is electrically connected or disconnected from the charging pile.

[0060] Understandably, by setting up charging stations, the inspection robot 2 and the firefighting robot 3 can automatically return to the charging position for charging without human intervention, thus automating the charging process. Automated charging reduces downtime caused by insufficient power, ensuring that the robots can continuously perform inspection and firefighting tasks. Furthermore, by setting up a lifting drive 6 to connect the charging connector 7 to the charging station, the operation of the inspection robot 2 and the firefighting robot 3 is prevented from being affected by the charging station. Only during charging, the lifting drive 6 on the inspection robot 2 and the firefighting robot 3 actively raises and lowers, thereby driving the charging connector 7 to electrically connect to the charging station.

[0061] The charging pile and charging connector 7 can be made using existing technologies, and the lifting drive component 6 can be made using existing technologies such as cylinders.

[0062] In one embodiment, a microphone 8 for collecting sound is also provided on the first mobile cabin 21.

[0063] Understandably, by setting up the microphone 8, the inspection robot 2 can also collect the sound of the environment where the belt conveyor 200 is located, so as to make it easier to determine whether there are abnormal noises, such as abnormal sounds generated by the belt conveyor 200 during operation, or sounds of items falling. This makes it easier for the inspection robot 2 to quickly discover abnormal situations on site that cannot be detected by the detection camera 22, thus improving reliability.

[0064] In one embodiment, both the first mobile cabin 21 and the second mobile cabin 31 are equipped with infrared cameras 9 for detecting the bearing temperature of the idler roller 202.

[0065] Understandably, by setting up an infrared camera 9, it is possible to detect situations such as high bearing temperatures caused by prolonged operation of the belt conveyor 200, thereby facilitating the notification of the fire-fighting robot 3 to cool down the high-temperature bearings.

[0066] In one embodiment, a servo motor 34 is provided at the bottom of the second mobile cabin 31, and the nozzle 331 of the fire extinguishing device 33 is mounted on the servo motor 34. The servo motor 34 can rotate to adjust the orientation of the nozzle 331.

[0067] Understandably, by setting up a servo motor 34 and installing the nozzle 331 of the fire extinguishing device 33 on the servo motor 34, it is easy to adjust the orientation of the nozzle 331 in the event of a fire, thereby achieving fire extinguishing quickly and accurately.

[0068] During use, the fire-fighting robot 3 can accurately locate the high-temperature source through the infrared camera 9 installed on it, thereby guiding the servo motor 34 to adjust the orientation of the nozzle 331 and take timely and effective fire-fighting measures, which has good reliability.

[0069] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
