Description

Technical Field

[0001] This utility model relates to the field of inspection robot technology, specifically an anti-collision inspection robot. Background Technology

[0002] Rail-mounted inspection robots are commonly used in power distribution rooms to monitor real-time data on electrical cabinets, ensuring that the data is updated in real time and is controllable.

[0003] For example, patent publication number CN212312019U discloses a rail-mounted robot for inspection, which includes a track and a mobile trolley that walks on the track. A sliding contact rail is suspended below the track along the track direction. The mobile trolley includes a trolley body, a walking drive module, a mobile power supply module, a guide module, a lifting device, and a detection gimbal. The trolley body, the lifting device, and the detection gimbal are connected in sequence. The walking drive module is located on the upper part of the trolley body and rolls across the sliding contact rail to make contact with the upper part of the track. The guide module is located on the upper surface of the trolley body and rolls across the sliding contact rail to make contact with the side of the track. The mobile power supply module is connected to the guide module and extends into the sliding contact rail to draw power.

[0004] Although the above-mentioned device solves the problem of inconvenient disassembly and assembly, it still has the following defects: when the rail-mounted inspection robot is used to inspect the power distribution room, if some ladders or other tools are left under the track in the power distribution room, the camera of the rail-mounted robot will be hit when it walks along the track. Therefore, the existing rail-mounted inspection robot does not have a structure to prevent the camera from being hit. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a collision-proof inspection robot, so that the inspection robot can protect the front and rear sides of the camera group when it walks along the track.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a collision-resistant inspection robot, comprising an inspection robot body, a lifting platform connected to the inspection robot body, and a camera group connected to the bottom of the lifting platform. The outer wall of the lifting platform is equipped with an installation frame, and a protective plate for fitting around the camera group is slidably connected to the outer side of the installation frame. Two symmetrically arranged installation sleeves are fixedly connected to the outer wall of the installation frame, and electric push rods are fixedly installed inside the installation sleeves. The output ends of the two electric push rods are respectively fixedly connected to the corresponding protective plates.

[0007] Furthermore, the outer wall of the protective plate is connected to a buffer plate, the inner wall of the buffer plate is fixedly connected to a sliding rod, the outer wall of the protective plate is fixedly connected to a fixing sleeve, the sliding rod is slidably connected inside the fixing sleeve, and a spring is sleeved on the outer side of the sliding rod. One end of the spring is fixedly connected to the sliding rod, and the other end is fixedly connected to the outer end of the fixing sleeve. A pressure sensor is fixedly connected to the outer wall of the protective plate.

[0008] Furthermore, a protective padding layer is fixedly connected to the outer wall of the buffer plate.

[0009] Furthermore, a guide block is fixedly connected to the outer wall of the mounting frame, and a slide bar that is slidably connected to the guide block is fixedly connected to the inner wall of the protective plate.

[0010] Furthermore, a U-shaped limiting block is engaged at the top of the slide bar, the bottom surface of the U-shaped limiting block abuts against the top surface of the guide block, and a bolt is threadedly connected to the top of the U-shaped limiting block. The bolt passes through the U-shaped limiting block and is threadedly connected to the slide bar.

[0011] Furthermore, the outer wall of the mounting frame is threaded with multiple fastening screws, which pass through the mounting frame and are threadedly connected to the lifting platform.

[0012] Furthermore, the cross-section of the slider is T-shaped or dovetail-shaped.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention, by installing a liftable protective plate on the lifting platform, ensures that the camera assembly remains effectively protected during the movement of the inspection robot, preventing direct impact to the camera assembly during robot movement. The protective plate is installed on the outside of the lifting platform, providing comprehensive protection for the camera assembly regardless of its position, ensuring its safe and stable operation.

[0016] 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.

[0017] like Figures 1 to 4 As shown, an anti-collision inspection robot includes an inspection robot body 1, a lifting platform 2 connected to the inspection robot body 1, and a camera group 8 connected to the bottom of the lifting platform 2. The outer wall of the lifting platform 2 is equipped with a mounting frame 4. A protective plate 3 for fitting around the camera group 8 is slidably connected to the outer side of the mounting frame 4. Two symmetrically arranged mounting sleeves 16 are fixedly connected to the outer wall of the mounting frame 4. Electric push rods 12 are fixedly installed inside the mounting sleeves 16. The output ends of the two electric push rods 12 are respectively fixedly connected to the corresponding protective plates 3.

[0018] like Figure 1 As shown, the anti-collision inspection robot of this utility model is structurally similar to existing rail-mounted robots used for inspection, such as the rail-mounted robot for inspection disclosed in patent publication number CN212312019U. The main improvement of this utility model is that it enables the inspection robot to protect the front and rear sides of the camera group while walking along the track. Figures 1 to 4 As shown, when the anti-collision inspection robot of this utility model is in use, the inspection robot body 1 walks along the track to read and check the data of the electrical cabinet in the power distribution room. The inspection process is as follows: the inspection robot body 1 first walks to the designated position, and then the lifting platform 2 descends to the preset height. The camera group 8 checks the values ​​of the electrical cabinet. After the area is checked, it moves to the next designated position for inspection. In this way, the inspection robot body 1 completes the reading and checking of the electrical cabinet data in the power distribution room. Finally, the inspection robot body 1 returns to the destination and waits for the next inspection instruction.

[0019] When the inspection robot body 1 is at the end position, the protective plate 3 is always located outside the lifting platform 2 and the camera group 8, thus ensuring that the camera group 8 is always protected. When the inspection robot body 1 receives the inspection command, it moves on the track according to the settings. During the movement, the protective plate 3 does not open. When it moves to the designated position, the inspection robot body 1 controls the two electric push rods 12 to start, so that the output ends of the two electric push rods 12 move and push the protective plates 3 on both sides to rise, exposing the camera group 8. In order to ensure the normal rotation of the camera group 8, the protective plates 3 on both sides need to be moved upward to leave enough space for the camera group 8 to rotate and facilitate inspection. When the area is inspected and it is necessary to move to the next position, the output ends of the two electric push rods 12 are reset respectively. After the protective plate 3 is reset, the camera group 8 can still be protected while moving with the inspection robot body 1 along the track, preventing direct impact and damage to the camera group 8 during the movement. In this way, the protective plate 3 lowers to protect when the inspection robot body 1 moves, and rises after moving to the designated position to expose the camera group 8 for easy inspection.

[0020] In practical applications, the two electric actuators 12 can be electrically connected to the main unit of the inspection robot body 1 via cables. Sufficient cable length should be provided to ensure the cable can unfold during the lifting process of the lifting platform 2. Alternatively, wireless electric actuators 12 can be selected, transmitting control commands via wireless communication technologies (such as radio frequency, Bluetooth, infrared, etc.). There is no physical wire connection between the control end and the execution end, facilitating wireless lifting of the lifting platform 2 and utilizing a battery for power. Both wired and wireless electric actuators 12 are existing known technologies, therefore, detailed descriptions of relevant models are not provided here.

[0021] By installing a liftable protective plate 3 on the lifting platform 2, the camera assembly 8 can be effectively protected during the movement of the inspection robot body 1, preventing direct impact to the camera assembly 8 when the robot moves. The protective plate 3 is installed on the outside of the lifting platform 2, providing comprehensive protection for the camera assembly 8 regardless of its position, ensuring its safe and stable operation.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the outer wall of the protective plate 3 is connected to a buffer plate 5. The inner wall of the buffer plate 5 is fixedly connected to a slide rod 13. The outer wall of the protective plate 3 is fixedly connected to a fixing sleeve 6. The slide rod 13 is slidably connected inside the fixing sleeve 6. A spring 14 is sleeved on the outer side of the slide rod 13. One end of the spring 14 is fixedly connected to the slide rod 13, and the other end is fixedly connected to the outer end of the fixing sleeve 6. A pressure sensor 17 is fixedly connected to the outer wall of the protective plate 3.

[0023] Specifically, when the inspection robot body 1 moves the camera group 8, the buffer plate 5 on the outer side of the protective plate 3 is always located outside the protective plate 3. If an object hits the buffer plate 5, the buffer plate 5 moves backward, causing the slide rod 13 to slide within the fixed sleeve 6, while simultaneously compressing the spring 14. When the buffer plate 5 presses against the pressure sensor 17, the inspection robot body 1 will stop abruptly on the track and move backward, preventing the inspection robot body 1 from continuing to move. It can also trigger a fault alarm work order to remind maintenance personnel to repair it. In practical applications, the pressure sensor 17 can still be selected for wired or wireless connection. For example, the wireless pressure sensor 17 transmits detection signals through wireless communication technology (such as radio frequency, Bluetooth, LoRa, etc.), without the need for physical wires, and is powered by a battery. The above-mentioned wired or wireless sensors are all existing known technologies, and the relevant models will not be described in detail here.

[0024] With the setup of buffer plate 5, slide bar 13, and fixed sleeve 6, when an object is about to collide, it will impact buffer plate 5. Buffer plate 5 can buffer part of the impact force under the setup of slide bar 13 and fixed sleeve 6, avoiding the impact force from acting directly on the protective plate 3. Pressure sensor 17 can make the inspection robot body 1 stop suddenly and move backward on the track, further reducing the impact force.

[0025] like Figure 4 As shown, a protective padding layer is fixedly connected to the outer wall of the buffer plate 5. The protective padding layer provides a secondary cushioning effect.

[0026] like Figure 3 and Figure 4 As shown, a guide block 9 is fixedly connected to the outer wall of the mounting frame 4, and a slide bar 7, which is slidably connected to the guide block 9, is fixedly connected to the inner wall of the protective plate 3. When the protective plate 3 is raised or lowered, the slide bar 7 will rise or fall within the guide block 9. This arrangement ensures the stable raising and lowering of the protective plate 3.

[0027] like Figure 3 and Figure 4 As shown, a U-shaped limiting block 11 is engaged at the top of the slide bar 7. The bottom surface of the U-shaped limiting block 11 abuts against the top surface of the guide block 9. A bolt 15 is threadedly connected to the top of the U-shaped limiting block 11, and the bolt 15 passes through the U-shaped limiting block 11 and is threadedly connected to the slide bar 7. The U-shaped limiting block 11 allows the electric actuator 12 to bear part of the weight of the protective plate 3, so that the protective plate 3 does not need to rely entirely on the weight of the output end of the electric actuator 12 during the protection process. Furthermore, the bolt 15 can be removed to disassemble the U-shaped limiting block 11 and smoothly detach the protective plate 3 from the mounting frame 4.

[0028] like Figure 2 and Figure 3As shown, the outer wall of the mounting frame 4 is threaded with multiple fastening screws 10, which pass through the mounting frame 4 and are threadedly connected to the lifting platform 2. The fastening screws 10 facilitate the installation and removal of the mounting frame 4.

[0029] like Figure 3 and Figure 4 As shown, the cross-section of the slider 7 is T-shaped or dovetail-shaped. The T-shaped or dovetail-shaped slider 7 can ensure that the slider 7 slides stably within the guide block 9.

[0030] 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.
