[0052] The terms "first", "second", "third", "fourth", etc. in the description and claims of this application and the above drawings are used to distinguish similar objects and do not have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application described here, for example, can be implemented in an order other than those illustrated or described here.

[0053] In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0054] In the related art, the inspection device includes walking drive wheels. A chute that matches part of the conductors or ground wires of the overhead transmission line is provided on the circumferential side of the walking drive wheels. The walking drive wheels are mounted above the conductors or ground wires of the overhead transmission line through the chute, so that the inspection device is arranged on the conductors or ground wires of the overhead transmission line. Then, the inspection device moves along the extension direction of the conductors or ground wires of the overhead transmission line by the rolling contact between the walking drive wheels and the conductors or ground wires of the overhead transmission line to perform inspections.

[0055] However, during the process of the above-mentioned inspection device moving for inspection while being arranged on the conductors or ground wires of the overhead transmission line, the stability is poor and it is prone to shaking, resulting in low inspection efficiency.

[0056] In view of this, the present application provides an inspection device. By providing a connecting member and a lifting mechanism, the device body is slidably connected to the connecting member through the lifting mechanism, so that the placing portion of the connecting member is arranged opposite to the walking driving member of the device body. When the inspection device is arranged on the conductors or ground wires of the overhead transmission line, by making the placing portion be mounted above the conductors or ground wires of the overhead transmission line, and then using the lifting mechanism to drive the device body to move towards the placing portion, that is, towards the conductors or ground wires of the overhead transmission line, so that the walking driving member abuts against the bottom of the conductors or ground wires of the overhead transmission line.

[0057] In this way, the inspection device is hung on the conductors or ground wires of the overhead transmission line through the placing portion, and the conductors or ground wires of the overhead transmission line are limited and supported by the walking driving member, which is beneficial to improving the stability of the inspection device arranged on the conductors or ground wires of the overhead transmission line; during the process of driving the device body and the connecting member to move along the extension direction of the conductors or ground wires of the overhead transmission line by the rolling contact between the walking driving member and the conductors or ground wires of the overhead transmission line, the frictional resistance between the inspection device and the conductors or ground wires of the overhead transmission line can be reduced, so as to further avoid the relative displacement between the conductors or ground wires of the overhead transmission line and the inspection device, and prevent the inspection device from being separated from the conductors or ground wires of the overhead transmission line due to unnecessary shaking during the movement, ensuring that the movement of the inspection device is smoother, and thus improving the inspection efficiency.

[0058] Hereinafter, the present application will be described in detail with reference to the drawings and specific embodiments.

[0059] Refer to Figures 1 to 4, the inspection device provided by the embodiment of the present application includes a device body 100, a connecting member 200, and a lifting mechanism 400; the device body 100 is slidably connected to the connecting member 200 through the lifting mechanism 400, the device body 100 includes a traveling driving member 110, and the connecting member 200 has a placing portion 210, and the traveling driving member 110 is disposed opposite to the placing portion 210; the placing portion 210 is used to be disposed above the conductor or ground wire 500 of the overhead transmission line, and the lifting mechanism 400 is configured to drive the device body 100 to move towards the placing portion 210 so that the traveling driving member 110 abuts against the bottom of the conductor or ground wire 500 of the overhead transmission line; the traveling driving member 110 is configured to rollingly contact the conductor or ground wire 500 of the overhead transmission line to drive the device body 100 and the connecting member 200 to move along the extending direction of the conductor or ground wire 500 of the overhead transmission line.

[0060] It should be noted that the overhead transmission line in the embodiment of the present application is a power transmission facility erected above the ground and is used to transmit electric energy between two points of the system. The overhead transmission line mainly consists of main components such as conductors, lightning conductors (overhead ground wires), towers, insulators, and fittings. These components work together to ensure that the current can be safely and effectively transmitted from the power station to the user end. As the main current carrier, the conductor usually adopts a steel-cored aluminum stranded wire to optimize the conductivity and mechanical strength. The lightning conductor is installed above the conductor and grounded through the tower to reduce the chance of lightning directly hitting the conductor. The tower is used to support the conductor and the lightning conductor and keep a safe distance between them and the ground and other structures. The insulator ensures the electrical isolation between the conductor and the tower to prevent current leakage. The inspection device in the embodiment of the present application can be used to be disposed on the conductor of the overhead transmission line, or can be used to be disposed on the ground wire of the overhead transmission line, or two inspection devices can be provided and respectively disposed on the conductor and the ground wire, and there is no limitation thereto.

[0061] Specifically, the device body 100, as the carrier of the inspection system, includes components such as a traveling driving member 110 and has the functions of monitoring, receiving, and transmitting data; the embodiment of the present application does not limit the specific structure of the device body 100 as long as it has the above functions and is portable and easy to carry.

[0062] The connecting member 200 is used to be slidably connected to the device body 100 through the lifting mechanism 400 and uses the placing portion 210 to provide a hanging point for the placement of the device body 100 on the conductor or ground wire 500 of the overhead transmission line.

[0063] The traveling driving member 110 is used after the placing portion 210 is erected above the conductor or ground wire 500 of the overhead transmission line, such as Figure 3 and Figure 4As shown in the figure, under the action of the lifting mechanism 400, it moves along with the equipment body 100 towards the placing part 210 and abuts against the bottom of the conductor or ground wire 500 of the overhead transmission line. Thus, when the equipment body 100 and the connecting member 200 move along the extension direction of the conductor or ground wire 500 of the overhead transmission line, it plays a role in supporting and limiting the conductor or ground wire 500 of the overhead transmission line, preventing the conductor or ground wire 500 of the overhead transmission line from slipping out between the placing part 210 and the traveling driving member 110.

[0064] In the embodiment of the present application, the specific structures of the lifting mechanism 400 and the connecting member 200 are not limited, as long as the equipment body 100 can be slidably connected to the connecting member 200 through the lifting mechanism 400, and the equipment body 100 can be stably hung on the conductor or ground wire 500 of the overhead transmission line.

[0065] Exemplarily, the partial structure of the connecting member 200 that is slidably connected to the equipment body 100 can be set to a shape matching the equipment body 100, and has a sufficient surface area to ensure a relatively reliable connection with the equipment body 100.

[0066] Combined Figure 3 and Figure 4 As shown in the figure, the extension direction of the conductor or ground wire 500 of the overhead transmission line is the X direction. Specifically, when implemented, the placing part 210 of the connecting member 200 can be set to a plate-like structure, and the number of the placing parts 210 is set to one. The projection part of the placing part 210 facing the equipment body 100 is located on the equipment body 100. That is to say, the length of the placing part 210 in the Figure 3 and Figure 4 shown X direction is greater than the length of the equipment body 100 in the X direction. The equipment body 100 is located at the middle position of the placing part 210. Exemplarily, sockets 211 matching the conductor or ground wire 500 of the overhead transmission line can be provided at the opposite ends of the placing part 210 in the X direction. In this way, the placing part 210 is erected above the conductor or ground wire 500 of the overhead transmission line through the sockets 211, so that when the equipment body 100 is hung on the conductor or ground wire 500 of the overhead transmission line, the overall inspection equipment has good balance and stability.

[0067] Alternatively, the placing part 210 can also be set to a rod-like structure, and the number of the placing parts 210 is set to multiple. Multiple placing parts 210 are all connected to the connecting member 200, and each placing part 210 is along Figure 3The X-direction interval setting shown. Exemplarily, the placement part 210 as a whole is a V-shaped rod. Each placement part 210 is jointly mounted on the conductor or ground wire 500 of the overhead transmission line through the V-shaped opening, so that the device body 100 can be hung on the conductor or ground wire 500 of the overhead transmission line. In addition, the bottom area of the V-shaped rod opposite to the opening, that is, the area where the placement part 210 contacts the conductor or ground wire 500 of the overhead transmission line, can be set as an arc segment matching the conductor or ground wire 500 of the overhead transmission line, which is beneficial to providing the stability of the placement part 210 mounted on the conductor or ground wire 500 of the overhead transmission line.

[0068] Here, it should be noted that in combination with Figure 4 shown, rollers 212 or sliding sleeves can also be configured for the placement part 210. In this way, when the traveling driving part 110 drives the device body 100 to move, the friction between the placement part 210 and the conductor or ground wire 500 of the overhead transmission line can be reduced.

[0069] Furthermore, the lifting mechanism 400 can include an electric push rod, a guide rail and a slider slidably connected to the guide rail. By fixing the guide rail on the connecting part 200, the device body 100 cooperates with the guide rail through the slider, which is beneficial to improving the connection reliability between the device body 100 and the connecting part 200 on the basis of realizing up and down sliding. The electric push rod can be arranged on the connecting part 200 and is located on the opposite sides of the device body 100 from the placement part 210. That is to say, when the inspection device is placed on the conductor or ground wire 500 of the overhead transmission line, the placement part 210 is located above the device body 100, and the electric push rod is located below the device body 100. In this way, by connecting the electric push rod and the device body 100, the driving force required for the lifting action of the device body 100 can be provided by the electric push rod, and then the device body 100 can be moved towards the placement part 210.

[0070] It should be noted that the connecting part 200 and the device body 100 can also be connected through a telescopic sleeve, so as to replace the sliding connection method of the guide rail - slider. Among them, a guiding device can also be configured in the telescopic sleeve to ensure the smoothness of sliding.

[0071] It can be understood that in specific implementation, the traveling driving part 110 can include a motor and a driving wheel connected to the motor. The motor provides a rotational torque for the driving wheel, so that the driving wheel rotates on the basis of rolling with the conductor or ground wire 500 of the overhead transmission line, and drives the device body 100 and the connecting part 200 to move.

[0072] In summary, the inspection device according to the embodiments of the present application is hung on the conductor or ground wire 500 of the overhead transmission line through the placement part 210, and the walking driving part 110 is used to limit and support the conductor or ground wire 500 of the overhead transmission line, thereby facilitating the improvement of the stability of the inspection device arranged on the conductor or ground wire 500 of the overhead transmission line; when the walking driving part 110 is in rolling contact with the conductor or ground wire 500 of the overhead transmission line to drive the device body 100 and the connecting part 200 to move along the extending direction of the conductor or ground wire 500 of the overhead transmission line, the frictional resistance between the inspection device and the conductor or ground wire 500 of the overhead transmission line can be reduced, so as to further avoid the relative displacement between the conductor or ground wire 500 of the overhead transmission line and the inspection device, and prevent the inspection device from being separated from the conductor or ground wire 500 of the overhead transmission line due to unnecessary shaking during the movement, ensuring that the movement of the inspection device is more stable and smooth, and thus improving the inspection efficiency.

[0073] Referring to Figure 1 、 Figure 2 and Figure 5 In some embodiments, the connecting part 200 includes a connecting portion 220. One side of the connecting portion 220 is connected to the placement part 210, and the other side of the connecting portion 220 extends in a direction away from the placement part 210; the device body 100 is slidably connected to the connecting portion 220 through a lifting mechanism 400.

[0074] Specifically, the connecting portion 220 is used to connect the placement part 210 and the device body 100 and provide a sliding path for the device body 100.

[0075] The present application does not limit the specific structure of the connecting portion 220. Exemplarily, the connecting portion 220 can be set as a U-shaped or C-shaped plate structure matching the device body 100. As mentioned above, the placement part 210 can be set as a plate structure. In this way, the connecting portion 220 provides a sufficient supporting area for the device body 100 when the device body 100 slides thereon; ensuring the flexible adjustment of the device body 100 in the vertical direction, where the vertical direction is the Figure 1 Z direction shown in the figure, and at the same time, it also provides additional stability for the device.

[0076] It can be understood that by connecting one side of the connecting portion 220 to the placement part 210 and extending the other side of the connecting portion 220 in a direction away from the placement part 210, when the connecting part 200 is arranged on the conductor or ground wire 500 of the overhead transmission line, the overall side view of the connecting part 200 can be designed in an inverted L shape.

[0077] Referring to Figure 5 and Figure 6, in a specific example, the connecting portion 220 includes a first connecting segment 221, a second connecting segment 222, a third connecting segment 223, and a fourth connecting segment 224 that are sequentially connected. The first connecting segment 221 and the third connecting segment 223 are disposed opposite to each other, and the second connecting segment 222 and the fourth connecting segment 224 are disposed opposite to each other to jointly enclose a placement area 202; one of the first connecting segment 221 and the third connecting segment 223 is connected to the placement portion 210, the device body 100 is placed on the placement area 202, and both the second connecting segment 222 and the fourth connecting segment 224 are slidably connected to the device body 100 through a partial lifting mechanism 400.

[0078] In this way, the structure of the connecting portion 220 is more streamlined, and the lightweight design of the inspection device body 100 can be achieved.

[0079] Exemplarily, the first connecting segment 221 and the third connecting segment 223 can be designed as an L shape or a T shape to facilitate connection to the placement portion 210 and provide a sufficient support area. Among them, one of the first connecting segment 221 and the third connecting segment 223 can be fixedly connected to the placement portion 210 by means of welding or bolt connection to ensure a firm and reliable connection.

[0080] The second connecting segment 222 and the fourth connecting segment 224 can be designed as straight segments or arc segments to facilitate sliding connection with the device body 100; the placement area 202 is enclosed by the first connecting segment 221, the second connecting segment 222, the third connecting segment 223, and the fourth connecting segment 224, and can be designed according to the size and shape of the device body 100, such as a rectangular, square, or other shaped space.

[0081] Refer to Figure 1 and Figure 7 , in some examples, the lifting mechanism 400 includes a sliding assembly 410, and the sliding assembly 410 includes at least one first sliding member 411 and at least one second sliding member 412; the first sliding member 411 is slidably sleeved on the second connecting segment 222, the second sliding member 412 is slidably sleeved on the fourth connecting segment 224, and both the first sliding member 411 and the second sliding member 412 are connected to the device body 100.

[0082] Specifically, the first sliding member 411 is slidably sleeved on the second connecting segment 222 and is connected to the device body 100. It is used to provide a fulcrum for one side of the device body 100 to move in the direction towards the placement portion 210 to ensure that the device body 100 can be lifted and lowered smoothly.

[0083] The second sliding member 412 is slidably sleeved on the fourth connecting section 224 and is also connected to the device body 100. It is used to provide a fulcrum for the other side of the device body 100 to move in the direction towards the placement portion 210. By cooperating with the first sliding member 411, it jointly supports the device body 100 and enhances the stability of the device body 100.

[0084] Exemplarily, the second connecting section 222 and the fourth connecting section 224, as the sliding tracks of the sliding members, can be designed as straight line segments or arc segments with a certain length to adapt to different height adjustment requirements of the device body 100.

[0085] Furthermore, the first sliding member 411 and the second sliding member 412 in the embodiments of the present application can both be designed as sliding sleeve structures. The inner diameter of the sleeve is slightly larger than the outer diameter of the connecting section, so that the sleeve can slide freely on the connecting section. Among them, the sleeve material can be selected as wear-resistant material to reduce wear, or balls or bearings can be provided on the sleeve wall to reduce the friction force during sliding.

[0086] Refer to Figure 6 , in some embodiments, the inspection device further includes four fasteners 300. The first connecting section 221 and the second connecting section 222, the first connecting section 221 and the fourth connecting section 224, the third connecting section 223 and the second connecting section 222, and the third connecting section 223 and the fourth connecting section 224 are connected through corresponding fasteners 300.

[0087] With such a setting, by fixing each connecting section together through the fasteners 300, the structural stability of the entire connecting member 200 can be significantly improved, ensuring that the connecting member 200 will not loosen due to factors such as vibration or wind force during the inspection process; avoiding potential safety hazards such as the device falling due to the loosening of the connecting member 200.

[0088] In specific implementation, the setting of the fasteners 300 enables quick assembly and disassembly between each connecting section, simplifying the installation and maintenance process of the device.

[0089] Refer to Figure 5 , Figure 6 , Figure 8 and Figure 9, Further, connection regions 201 are formed between the first connection segment 221 and the second connection segment 222, between the first connection segment 221 and the fourth connection segment 224, between the third connection segment 223 and the second connection segment 222, and between the third connection segment 223 and the fourth connection segment 224; the fastener 300 includes a fastening portion 310 and two abutting portions 320. The two abutting portions 320 are located on opposite sides of the corresponding connection region 201, and a projected portion of one of the two abutting portions 320 toward the connection region 201 is located on the other of the two abutting portions 320. One of the abutting portions 320 is connected to the other of the abutting portions 320 through the fastening portion 310.

[0090] Specifically, the connection region 201 may be a region formed by the interconnected portions of two adjacent connection segments. Through the connection by the fastener 300, the firmness of the connection region 201 is ensured, and the stability of the overall structure is enhanced.

[0091] The fastening portion 310 is used to connect the two abutting portions 320 to ensure that the fastener 300 can firmly fix the connection region 201; the abutting portions 320 are designed to be located on opposite sides of the connection region 201 and are connected through the fastening portion 310. A projected portion of one of the abutting portions 320 toward the connection region 201 is located on the other abutting portion 320, ensuring that the installation of the fastener 300 is more firm and reliable.

[0092] Exemplarily, the fastening portion 310 may be designed as a bolt or a buckle so that the two abutting portions 320 can be connected by a threaded connection or a snap connection; the abutting portions 320 may be designed as a ring or other shapes to facilitate being sleeved on both sides of the connection region 201.

[0093] Specifically, when implemented, the four fasteners 300 may be two first sub-fasteners 301 and two second sub-fasteners 302 as shown in Figure 6 wherein, the first sub-fastener 301 has a structure as shown in Figure 8 and the second sub-fastener 302 has a structure as shown in Figure 9 The lower ends of the second connection segment 222 and the fourth connection segment 224 are respectively connected to the corresponding ends of the first connection segment 221 through the first sub-fasteners 301, and the upper ends of the second connection segment 222 and the fourth connection segment 224 are respectively connected to the corresponding ends of the third connection segment 223 through the second sub-fasteners 302, so that the first connection segment 221 is located on the side of the second connection segment 222, the third connection segment 223 and the fourth connection segment 224, while the second connection segment 222, the third connection segment 223 and the fourth connection segment 224 are located in the same plane, as shown in Figure 1 and Figure 4 shown. By setting like this, the layout of each component can be rationalized, facilitating the overall assembly operation of the wire-hanging robot.

[0094] It should be noted that on the basis of achieving the above object, the structure of the first sub-fastener 301 can be adaptively designed. Taking the connection of the second connection section 222 to the first connection section 221 through the first sub-fastener 301 as an example, Figure 8 as shown, two abutting portions 320 of the first sub-fastener 301 can be integrally formed. The two abutting portions 320 together define a first mounting groove matching the first connection section 221 and a second mounting groove matching the second connection section 222. To facilitate the disassembly and assembly between the first connection section 221 and the first mounting groove, and between the second connection section 222 and the first mounting groove, notches are provided on the groove walls of both the first mounting groove and the second mounting groove. In this way, by applying a fastening force to the groove walls on both sides of the notch through the fastening portion 310, the structural stability during installation can be ensured. At the same time, when the first sub-fastener 301 needs to be disassembled, after removing the fastening portion 310, the presence of the notch facilitates the removal of the first connection section 221 and the second connection section 222.

[0095] In a specific example, the placement area 202 is rectangular.

[0096] In this way, the connector 200 as a whole can be designed as a rectangular frame or a rectangular platform, with a simple and regular structure, which can provide a stable foundation for the device body 100 and make the device body 100 move more smoothly.

[0097] Furthermore, the rectangular design simplifies the design and manufacturing process of the connector 200 and reduces the production cost.

[0098] In a specific example, the first connection section 221, the second connection section 222, the third connection section 223, and the fourth connection section 224 are all straight rods.

[0099] In this way, the straight rod structure is relatively simple, reducing the complexity of manufacturing and assembly, and lowering the production and maintenance costs; at the same time, the straight rod structure can more effectively distribute and bear forces, improving the strength of the overall structure.

[0100] In specific implementation, during the assembly process of the connector 200, the straight rod structure makes the connection between the connectors 200 easier to achieve and improves the assembly efficiency.

[0101] It can be understood that by setting the first connection section 221, the second connection section 222, the third connection section 223, and the fourth connection section 224 as straight rods, when selecting the fastener 300, it is convenient to fix them with standard fasteners 300, simplifying the structure of the fastener 300.

[0102] Exemplarily, the abutting portion 320 includes a first abutting segment 321 and a second abutting segment 322 that is perpendicularly connected to the first abutting segment 321. Both the first abutting segment 321 and the second abutting segment 322 have an arc-shaped groove 323 that matches a part of the straight rod.

[0103] In this way, the structure of the abutting portion 320 is relatively simple. Through the design of the arc-shaped groove 323, the contact between the straight rod and the abutting portion 320 is closer, increasing the contact area, reducing the possibility of sliding, and improving the connection stability.

[0104] Specifically, the first abutting segment 321 and the second abutting segment 322 can be integrally formed.

[0105] In some embodiments, the straight rod is a carbon fiber tube.

[0106] By setting the straight rod as a carbon fiber tube, the low density of the carbon fiber tube can reduce the overall weight of the inspection device, thereby improving the portability and transportation efficiency of the inspection device.

[0107] Specifically, the carbon fiber material has good strength and rigidity, and can provide sufficient supporting force even under a relatively thin wall thickness, ensuring the structural stability of the device during use.

[0108] The carbon fiber material has good fatigue resistance and can withstand long-term repeated use without being prone to fatigue fracture; the carbon fiber material can still maintain good mechanical properties under high or low temperature environments, and can adapt to the inspection work of the inspection device under various extreme climate conditions.

[0109] Refer to Figures 1 to 4 , in some embodiments, the lifting mechanism 400 further includes a power member 420 and a transmission assembly 430; the power member 420 is disposed on the device body 100; the transmission assembly 430 includes a first transmission member 431 and a second transmission member 432 that is in transmission connection with the first transmission member 431. The first transmission member 431 is connected to the power member 420, and the second transmission member 432 is connected to the connecting portion 220; the power member 420 is used to drive the first transmission member 431 to start, and the first transmission member 431 is used to drive the power member 420 to move relative to the second transmission member 432 when starting, so that the device body 100 is lifted or lowered relative to the connecting portion 220 to approach or move away from the placing portion 210.

[0110] In this way, the rapid lifting and lowering of the device body 100 is achieved through the cooperation of the power member 420 and the transmission assembly 430, which is beneficial to improving the efficiency of adjusting the height of the device body 100.

[0111] Specifically, the power component 420 is arranged on the device body 100 and is used to provide the driving force required for the lifting of the device body 100; the design of the transmission assembly 430 enables the power generated by the power component 420 to be effectively converted into the lifting motion of the device body 100, ensuring that the device body 100 can approach or move away from the placing part 210 smoothly.

[0112] Among them, the first transmission member 431 is connected to the power component 420 and is used to transmit the power generated by the power component 420 to the second transmission member 432. The second transmission member 432 is connected to the connecting part 220, and through the transmission connection with the first transmission member 431, the lifting of the device body 100 relative to the connecting part 220 is realized.

[0113] The specific type of the transmission assembly 430 in the embodiments of the present application is not limited. Exemplarily, the first transmission member 431 can be set as a sprocket, and the second transmission member 432 is a chain that is in transmission cooperation with the sprocket. The chain is connected to the transmission member, and the sprocket drives the device body 100 to lift along the connecting part 220 through the chain. Specifically, the power component 420 can be an electric motor, which has the advantages of fast response speed and high control precision; the device body 100 is lifted by electric energy; in addition, the power component 420 can also be set as a hydraulic motor, and the device body 100 is lifted by the pressure of hydraulic oil. Or, a pneumatic motor can also be used as the power component 420, and the device body 100 is lifted by the pressure of compressed air.

[0114] In a specific example, the first transmission member 431 is a gear, and the second transmission member 432 is a rack that matches the gear; the extending direction of the rack is parallel to the extending direction of the connecting part 220, and the power component 420 is used to drive the gear to rotate, so that the gear meshes with the rack for transmission, so as to drive the power component 420 and the device body 100 to move relative to the rack.

[0115] In this way, the cooperation of the gear and the rack can provide high-precision transmission, ensuring that the position control of the device body 100 during the lifting process is more accurate; at the same time, the meshing transmission method of the gear and the rack can provide stable power transmission, which is beneficial to reducing the possible shaking or jitter phenomenon of the device body 100 during the lifting process.

[0116] Specifically, by controlling the rotation speed and direction of the power component 420 to change the rotation speed and direction of the gear, the height adjustment of the device body 100 can be realized more conveniently, which is beneficial to improving the flexibility and convenience of operation.

[0117] In order to ensure sufficient rigidity and stability for the installation of the rack to avoid deformation or loosening during use. Refer to Figure 6 and Figure 7, in some examples, the lifting mechanism 400 further includes two fixing members 450. One end of the rack in the extending direction is connected to the first connection segment 221 through one of the two fixing members 450, and the other end of the rack in the extending direction is connected to the third connection segment 223 through the other of the two fixing members 450; or, both ends of the rack in the extending direction are connected to one of the second connection segment 222 and the fourth connection segment 224 through the corresponding fixing member 450; so that the rack is disposed opposite to the device body 100 and is located on the side of the gear.

[0118] In this way, the rack is fixed to the connection segment by the fixing member 450, which can ensure the stability of the rack during the lifting process of the device body 100 and reduce the problem of instability of the device body 100 caused by the shaking of the rack; exemplarily, the fixing member 450 makes the installation and disassembly of the rack more convenient, facilitating daily maintenance and component replacement.

[0119] In specific implementation, after the rack is installed on the connecting member 200 through the fixing member 450, the rack is disposed opposite to the device body 100 and is located on the side of the gear. In this way, the spatial layout of the device can be optimized, making the overall structure of the device more compact and reasonable, and reducing the occupied space.

[0120] Specifically, referring to Figure 9 and Figure 10 , the fixing member 450 includes a first fixing segment 451 and a bending segment 452 arranged in sequence. The first fixing segment 451 is connected to one of the first connection segment 221 and the third connection segment 223, and the bending segment 452 is connected to the end of the corresponding rack in the extending direction; or, the fixing member 450 includes a second fixing segment 453 and a sleeving segment 454 arranged in sequence. The sleeving segment 454 is sleeved on one of the second connection segment 222 and the fourth connection segment 224, and the second fixing segment 453 is connected to the end of the corresponding rack in the extending direction.

[0121] In this way, the fixing member 450 includes the first fixing segment 451 and the bending segment 452 arranged in sequence to connect the first fixing segment 451 to the first connection segment 221 or the third connection segment 223, and the bending segment 452 is connected to the end of the rack in the extending direction. To ensure that the rack can be firmly fixed to the connection segment, and at the same time, the setting of the bending segment 452 can better adapt to the shape and position of the rack.

[0122] Exemplarily, the first fixing section 451 and the bending section 452 can be integrally formed to ensure good connection strength therebetween. Among them, the first fixing section 451 can be set as a flat plate or a plate-like structure and connected to the first connection section 221 or the third connection section 223 by bolts, welding or other means to ensure that the fixing member 450 can be firmly fixed on the connection section; the bending section 452 can be set as a structure with an appropriate bending angle for connecting to the end of the rack in the extending direction. It should be noted that the design of the bending section 452 needs to ensure good fitting with the rack to improve the fixing strength.

[0123] Alternatively, the fixing member 450 includes a second fixing section 453 and a socket section 454 arranged in sequence. The second fixing section 453 is connected to the end of the rack in the extending direction, and the socket section 454 is sleeved on the second connection section 222 or the fourth connection section 224. In this way, it also ensures that the rack can be firmly fixed on the connection section. At the same time, the design of the socket section 454 enables the fixing member 450 to be conveniently installed and disassembled.

[0124] Exemplarily, the second fixing section 453 can be designed as a flat plate or a plate-like structure and connected to the end of the rack in the extending direction by bolts, welding or other means to ensure that the fixing member 450 can be firmly fixed on the rack; the abutting portion 320 can be designed as an annular or U-shaped structure matching the second connection section 222 for good fitting.

[0125] Refer to Figure 7 In some embodiments, the lifting mechanism 400 further includes a support member 440. The support member 440 is arranged on the equipment body 100. The support member 440 and the gear are located on opposite sides of the rack, and the support member 440 abuts against the rack.

[0126] In this way, the support member 440 can balance and disperse the load exerted by the equipment body 100 on the rack through the gear. Especially when the equipment body 100 is relatively heavy or the load changes greatly during the lifting process, it can better disperse the force and reduce the wear of the equipment body 100 on the gear and the rack; at the same time, as the main transmission components 430, the gear and the rack can be transmitted more smoothly through the auxiliary support of the support member 440, reducing the shaking of the equipment body 100 during the lifting process.

[0127] Exemplarily, the support member 440 can be set as a support wheel.

[0128] Refer to Figure 7 and Figure 11 In a specific example, the equipment body 100 includes a housing 120. The traveling driving member 110 is rotatably connected to the housing 120. The housing 120 is slidably connected to the connecting member 200. The power member 420 is arranged on the housing 120.

[0129] It can be understood that the housing 120, as the main load-bearing part of the device body 100, on the one hand, provides protection for the internal electronic devices and other components, and on the other hand, realizes the height adjustment of the device body 100 in the vertical direction through the sliding connection with the connecting member 200.

[0130] Specifically, a placement area 202 for rotatably connecting the walking driving member 110 is provided on the housing 120. Exemplarily, the walking driving member 110 includes a driving wheel, and the placement area 202 has a shape matching the driving wheel.

[0131] Furthermore, the power member 420 can be fixed to the housing 120 through fixing devices such as bolts and buckles to ensure the firm connection between the power member 420 and the housing 120.

[0132] Exemplarily, continue to refer to Figure 11 , the housing 120 has a receiving cavity 121, the power member 420 is placed in the receiving cavity 121, and an avoidance area 122 communicating with the receiving cavity 121 is formed on the housing 120. A part of the power member 420 extends out of the housing 120 through the avoidance area 122 to be connected to the first transmission member 431.

[0133] With such a setting, the overall structure of the device is more compact, saving space.

[0134] By placing the power member 420 in the receiving cavity 121 inside the housing 120, the power member 420 can be effectively protected from damage by the external environment, extending the service life of the power member 420.

[0135] Specifically, the avoidance area 122 can be designed as an opening on the housing 120, communicating with the receiving cavity 121. The size of the avoidance area 122 needs to be designed according to the size of the extending part of the power member 420 to ensure that the power member 420 can extend out smoothly and be connected to the first transmission member 431.

[0136] Exemplarily, the power member 420 is set as a motor, the first transmission member 431 is a gear, the motor is arranged in the receiving cavity 121, and by setting the avoidance area 122 as a hole matching the output shaft of the motor, the output shaft extends out of the housing 120 through the hole to be coaxially connected to the gear.

[0137] Furthermore, the inspection device further includes a sealing member 600, and the sealing member 600 is located between the avoidance area 122 and a part of the power member 420 to seal the gap between the avoidance area 122 and the part of the power member 420.

[0138] Specifically, the seal 600 is used to seal the gap between the avoidance area 122 and part of the power component 420, so as to prevent pollutants such as dust and moisture in the external environment from entering the interior of the device; reduce the wear and aging of the internal components of the device body 100, and extend the service life of the inspection device.

[0139] Exemplarily, the power component 420 is a motor, and the seal 600 is located between the avoidance area 122 and the output shaft of the motor.

[0140] It should be noted that the seal 600 in the embodiments of the present application can be selected according to actual needs, as long as it has good elasticity and wear resistance to ensure the sealing performance during the long-term operation of the device body 100. Exemplarily, the seal 600 can be designed as sealing materials such as rubber rings and sealing gaskets.

[0141] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
