Description

Technical Field

[0001] The present disclosure belongs to the field of automated inspection technology, and in particular relates to an inspection system. Background Art

[0002] When large equipment or systems (such as ships) are in operation, it is necessary to inspect the operating status of different components contained in the large equipment or the environmental conditions in which they are located, so as to grasp the changes in the equipment operating status and the surrounding environment in real time, so as to discover potential safety hazards during equipment operation early and ensure the safety of the equipment and the stability of the system.

[0003] To ensure smooth inspections, rails are typically installed around the equipment (including the perimeter and ceiling of the space where the equipment resides). A patrol vehicle is then controlled to move along these rails. The vehicle consists of a body, wheels connected to the body, a monitoring device, and a power unit that drives the vehicle along the rails. The power unit is attached to the body. As the vehicle moves, the monitoring device continuously records the equipment's operating status and the surrounding working environment.

[0004] If a patrol vehicle's power unit malfunctions during an inspection, it can become unusable. Furthermore, since the power unit is attached to the vehicle, it's difficult to replace, hindering inspection work. Furthermore, because patrol vehicles require dedicated guide rails for movement, this increases inspection costs and hinders widespread adoption. Summary of the Invention

[0030] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0031] The present disclosure provides a patrol inspection system. Figure 1 As shown, the inspection system includes a guide cable 1, a support assembly 2, a drive assembly 3, and an inspection vehicle 4. The support assembly 2 is located in the middle of the guide cable 1 and slides with it, keeping it in a straight position. The drive assembly 3 is located to one side of the guide cable 1 and spaced apart from the support assembly 2. The drive assembly 3 is used to drive the guide cable 1 relative to the support assembly 2 around the equipment to be inspected.

[0032] The inspection vehicle 4 is located on one side of the guide cable 1 and is connected to the guide cable 1 . The inspection vehicle 4 is configured to move following the guide cable 1 , and the moving path of the inspection vehicle 4 is around the equipment to be inspected.

[0033] When the inspection system provided by the embodiment of the present disclosure is inspecting the equipment to be inspected, since the inspection system includes a guide cable 1 and a support assembly 2, and the support assembly 2 slides with the guide cable 1 and enables the guide cable 1 to be stretched. In this way, the support assembly 2 can put the guide cable 1 in a stretched state, and the guide cable 1 in a stretched state can provide the premise for the movement of the guide cable 1. At the same time, since the inspection equipment also includes a drive assembly 3 and an inspection vehicle 4, and the drive assembly 3 slides with the guide cable 1 to drive the guide cable 1 to move relative to the support assembly 2, the inspection vehicle 4 is connected to the guide cable 1, and the inspection vehicle 4 can move synchronously with the guide cable 1. In this way, after being stretched, the guide cable 1 will move along its own extension direction. After the guide cable 1 moves, it will synchronously drive the inspection vehicle 4 to move, and then the equipment to be inspected will be inspected by the inspection vehicle 4.

[0034] Since the inspection vehicle 4 follows the guide cable 1 in the above inspection system, the inspection vehicle 4 can perform inspections without the need for a power unit, thereby avoiding situations where the inspection cannot be performed due to a malfunction of the power unit of the inspection vehicle 4. Furthermore, since the inspection vehicle 4 follows the guide cable 1, there is no need to install guide rails around the equipment to be inspected, which greatly simplifies the structure of the inspection system, reduces costs, and expands the scope of application of the inspection system.

[0035] In the disclosed embodiment, the guide cable 1 can be arranged on the top of the house where the equipment to be inspected is located, or on the periphery of the equipment, etc. As long as it does not affect the operation of the equipment to be inspected, the guide cable 1 can be arranged according to actual conditions.

[0036] The guide cable 1 is a flexible steel cable. Positioning the flexible guide cable 1 near the equipment to be inspected significantly reduces the number of mounting brackets typically required for conventional rail installations. Furthermore, the guide cable 1 is supported and guided by the support assembly 2, improving installation efficiency.

[0037] Optionally, both ends of the guide cable 1 are connected, and the support assembly 2 defines the guide cable 1 as a ring structure.

[0038] In the above implementation, the support component 2 limits the guide cable 1 to a closed ring structure, so that the guide cable 1 and the inspection vehicle 4 can move along the closed ring, thereby effectively increasing the inspection efficiency, avoiding the inspection vehicle 4 from taking a long route and returning, and increasing the inspection efficiency.

[0039] The closed annular structure is a polygon. The support assembly 2 includes a plurality of corner guide wheels 21. The plurality of corner guide wheels 21 are located within the annular structure and, together with the drive assembly 3, are located at the vertices of the polygon where the annular structure is located. The rotation axes of the corner guide wheels 21 are perpendicular to the plane where the annular structure is located.

[0040] In the disclosed embodiment, the annular structure is rectangular. The support assembly 2 includes three corner guide wheels 21. The three corner guide wheels 21 are located within the annular structure and, along with the drive assembly 3, are located at the four vertices of the rectangle in which the annular structure is located. The corner guide wheels 21 can rotate relative to the guide cable 1, and the rotation axis of the corner guide wheels 21 is perpendicular to the rectangular surface in which the annular structure is located.

[0041] In the above implementation, the closed annular structure is set as a rectangle, so that the inspection path of the inspection vehicle 4 is the perimeter of the rectangle, that is, the inspection route is in the shape of a U. This can effectively increase the inspection efficiency and avoid the inspection vehicle 4 having to go back for a long time.

[0042] Furthermore, by configuring the support assembly 2 with three corner guide wheels 21, the three corner guide wheels 21 can support three corners of the rectangle formed by the guide cables 1. Simultaneously, the three corner guide wheels 21 cooperate with the drive assembly 3 to define the rectangular shape of the guide cables 1. The drive assembly 3 also drives the guide cables 1. Specifically, the corner guide wheels 21 horizontally control the direction of the guide cables and enable obstacle avoidance.

[0043] In other examples, the number of the corner guide wheels 21 may be other numbers, such as four corner guide wheels 21 , which are respectively located at the four corners of the rectangle defined by the guide cable 1 . The drive assembly 3 is located between the two corner guide wheels 21 .

[0044] In the disclosed embodiment, to facilitate the fixing of the corner guide wheel 21, a fixing seat 211 is connected to one side of the corner guide wheel 21. The fixing seat 211 is located on the side of the corner guide wheel 21 away from the inspection vehicle 4. The fixing seat 211 is used to suspend the corner guide wheel 21 to provide guidance and support for the guide cable 1.

[0045] Exemplarily, the structure of the fixing base 211 can be formed by a wedge-shaped connecting block and a plate-shaped base plate. The wedge-shaped block is connected to the base plate and the corner guide wheel 21 respectively, and the base plate is used to be connected to other equipment so that the fixing base 211 can be fixed.

[0046] In other examples, the structure of the fixing seat 211 may also be other structures, such as a connecting rod, a rectangular block, etc.

[0047] Figure 2 for Figure 1 The left view, combined with Figure 2 Optionally, the support assembly 2 further includes a plurality of guide wheel groups 22 , which are spaced apart and located outside the annular structure and on the same side of the guide cable 1 as the inspection vehicle 4 .

[0048] The guide wheel group 22 includes a plurality of support guide wheels 222 connected together. The outer periphery of the support guide wheel 222 is in sliding contact with the bottom of the guide cable 1 , and the rotation axis of the support guide wheel 222 is perpendicular to the rotation axis of the corner guide wheel 21 .

[0049] In the above implementation, the support assembly 2 is further provided with a plurality of guide wheel assemblies 22, which can support the middle portion of the guide cable 1 via the plurality of guide wheel assemblies 22, ensuring that the guide cable 1 does not collapse but remains stretched. Furthermore, since the inspection vehicle 4 is connected to the guide cable 1, when the inspection vehicle 4 moves along with the guide cable 1, most or even all of the weight of the inspection vehicle 4 is borne by the guide cable 1. To prevent the inspection vehicle 4 from pulling and deforming the guide cable 1, the plurality of guide wheel assemblies 22 can support the guide cable 1, ensuring that the guide cable 1 remains stretched and does not deform.

[0050] That is, the corner guide wheel 21 in the support assembly 2 is used to support the corners of the rectangle defined by the guide cable 1, and the support guide wheel 222 is used to support the bottom of the guide cable 1 to prevent the guide cable 1 from sagging.

[0051] In this embodiment, there are two guide wheel assemblies 22 , and the two guide wheel assemblies 22 are respectively located at the bottom of the two opposite long sides of the rectangle defined by the guide cable 1 .

[0052] Combine Figure 1 Each guide wheel group 22 is provided with three supporting guide wheels 222, and the three supporting guide wheels 222 are arranged side by side along the direction of the long side of the rectangle.

[0053] To facilitate the arrangement of the three supporting guide wheels 222, the guide wheel assembly 22 also includes a connecting frame 223 and a connecting plate 224. The connecting frame 223 is located within the rectangle defined by the guide cable 1. The connecting frame 223 includes a top plate 2231, a plurality of connecting rods 2232, and a bottom frame 2233. The top plate 2231 is used to connect to other external devices to secure the connecting frame 223.

[0054] A plurality of connecting rods 2232 are spaced apart and located on a surface of the top plate 2231 facing the bottom frame 2233 , and one end of each connecting rod 2232 is connected to the top plate 2231 , and the other end is connected to the bottom frame 2233 .

[0055] The bottom frame 2233 is a trapezoidal structure formed by splicing together multiple connecting rods. The trapezoid formed by the bottom frame 2233 is located in a plane, and the plane where it is located is parallel to the top plate 2231 and perpendicular to the connecting rod 2232. The bottom frame 2233 is connected to the three support guide wheels 222.

[0056] The connecting plate 224 is located on a side of the three supporting guide wheels 222 away from the bottom frame 2233 . The connecting plate 224 is connected to the three supporting guide wheels 222 respectively so as to further connect the three supporting guide wheels 222 together.

[0057] In order to enable each supporting guide wheel 222 to be in sliding contact with the guide cable 1 , the outer circumference of the supporting guide wheel 222 has a groove, and the guide cable 1 is located in the groove of each supporting guide wheel 222 .

[0058] In other examples, the three support guide wheels 222 may also be connected to other structures, such as connecting rods, connecting plates, etc.

[0059] Continue to see Figure 1 Optionally, the driving assembly 3 includes a driving wheel 31 and a driving motor 32 . The driving wheel 31 is in sliding engagement with the guide cable 1 , and a rotation axis of the driving wheel 31 is perpendicular to the plane where the annular structure is located. The driving motor 32 is connected to the driving wheel 31 .

[0060] In the above implementation, the driving wheel 31 is used to rotate under the drive of the driving motor 32, and the driving wheel 31 is used to drive the guide cable 1 to move. The driving motor 32 serves as a power source to drive the driving wheel 31 to rotate.

[0061] Exemplarily, the driving wheel 31 may be a roller, and the driving wheel 31 drives the guide cable 1 to move through static friction.

[0062] In other examples, the driving wheel 31 may also be a pulley, and correspondingly, the guide cable 1 is a belt. In this case, the supporting guide wheel 222 and the corner guide wheel 21 may all be rolling wheels.

[0063] For example, a cable groove is provided on the outer periphery of the corner guide wheel 21 or the driving wheel 31 for accommodating the guide cable 1. Accommodating the guide cable 1 by the cable groove prevents the guide cable 1 from being separated from the corner guide wheel 21 or the driving wheel 31, but ensures that the guide cable 1 is in close contact with the corner guide wheel 21 or the driving wheel 31.

[0064] In this embodiment, to facilitate assembly of the drive motor 32, the drive assembly 3 further includes a mounting base 33. Mounting base 33 is an L-shaped plate formed by vertically connecting a top plate and side plates. The top plate of mounting base 33 is used to connect to external equipment. The drive motor 32 is located in the space defined by the top and side plates of mounting base 33 and is connected to the side plates of mounting base 33.

[0065] In other examples, the driving assembly 3 may also be other structures, for example, a driving power source formed by a worm gear, etc. to rotate the driving wheel 31.

[0066] Figure 3 for Figure 1The structural diagram of the inspection vehicle, combined with Figure 3 Optionally, the inspection vehicle 4 includes a vehicle body 41, a connecting arm 42, and a clamping head 44. The connecting arm 42 and the clamping head 44 are both located on the top of the vehicle body 41, one end of the connecting arm 42 is connected to the vehicle body 41, and the other end is connected to the clamping head 44. The clamping head 44 has a clamping space 440 inside for accommodating the guide cable 1.

[0067] In the above implementation, the inspection vehicle 4 is configured as described above. The vehicle body 41 provides a mounting base for the connecting arm 42 and the clamping head 44. The connecting arm 42 is used to connect the clamping head 44 to the vehicle body 41. The clamping head 44 is used to clamp together with the guide cable 1, so that the inspection vehicle 4 is fixed to the guide cable 1 and moves with it.

[0068] In the disclosed embodiment, the vehicle body 41 is a box-like structure with a hollow interior. This allows for the placement of more equipment, such as power batteries used by monitoring devices. This eliminates the need for cabling for the inspection system, making installation simple and quick, significantly reducing outfitting time.

[0069] In other words, the inspection vehicle 4 is changed from a conventional self-powered device to a self-powered device, which eliminates most of the transmission components and reduces the overall weight of the inspection vehicle 4. At the same time, the built-in power battery of the same volume can meet the inspection tasks of longer working conditions, increase the task time, reduce the number of times the power battery is charged and discharged, and extend the battery life.

[0070] Furthermore, the clamping head 44 on the top of the inspection vehicle 4 is arranged to be fixed together with the vehicle body 41 , so that the inspection vehicle 4 is conveniently fixed on the guide cable 1 and the inspection vehicle 4 is easy to assemble and disassemble.

[0071] Figure 4 for Figure 3 Schematic diagram of the structure of the clamping head. Figure 5 for Figure 4 Half-section view, combined with Figure 4 and Figure 5 Optionally, the clamping head 44 includes a clamping claw 441, two clamping blocks 442, and two clamping sleeves 444. The clamping claw 441 is sleeved outside the guide cable 1. The two clamping blocks 442 are located on opposite sides of the clamping claw 441 along the extension direction of the guide cable 1. Both clamping blocks 442 are in contact with the clamping claw 441, and both clamping blocks 442 are sleeved outside the guide cable 1.

[0072] The two clamping sleeves 444 are arranged in a one-to-one correspondence with the two clamping blocks 442, and each clamping sleeve 444 is sleeved outside the corresponding clamping block 442 and sleeved outside the clamping claw 441. Figure 4The clamping sleeve 444 on the left side is sleeved outside the left end portion of the clamping block 442 and the clamping claw 441 on the left side. The clamping sleeve 444 on the right side is sleeved outside the right end portion of the clamping block 442 and the clamping claw 441 on the right side.

[0073] Each clamping sleeve 444 can apply a radial force to the clamping claw 441 so that the clamping claw 441 and the guide cable 1 are clamped together.

[0074] In the above implementation, the clamping jaw 441 is clamped to the guide cable 1 by the action of the clamping sleeve 444. The clamping block 442 is used to limit the axial movement of the clamping jaw 441, thereby preventing the clamping jaw 441 from moving relative to the guide cable 1. The clamping sleeve 444 and the clamping block 442 are clamped together, facilitating assembly while also preventing the clamping block 442 from separating from the clamping jaw 441.

[0075] That is to say, first adjust the distance between the left and right clamping blocks 442 and the clamping claws 441 according to the length of the clamping claws 441 to ensure that the clamping claws 441 and the left and right clamping sleeves 444 are firmly connected, so that under the action of the clamping sleeves 444, the left and right clamping blocks 442 and the guide cable 1 are pressed tightly.

[0076] The clamping sleeve 444 has an inner flange 4441, and the clamping block 442 has an outer flange 4421. The outer flange 4421 of each clamping block 442 is sandwiched between the inner flange 4441 of the corresponding clamping sleeve 444 and the clamping claw 441. In this way, the clamping block 442 and the clamping sleeve 444 are arranged in a nested manner, which facilitates assembly.

[0077] In this embodiment, the clamping sleeve 444 is a nut, and the clamping claw 441 and the clamping sleeve 444 are threadedly connected. By threading the clamping sleeves 444 at both ends with the clamping claws 441, the position of the inspection vehicle 4 can be fixed on the guide cable 1. In other words, by effectively connecting the inspection vehicle 4 to the guide cable 1 using nuts and the like, the connection and installation requirements of the device can be simplified and the workload of interface verification can be effectively reduced.

[0078] In other examples, the structure of the clamping head 44 may also be other structures, for example, connected to the guide cable 1 through fasteners.

[0079] Optionally, the clamping claw 441 includes two half claws 4411 , each half claw 4411 has a semicircular cavity for accommodating the guide cable 1 , and the two half claws 4411 are butt-jointed and threadedly connected to the clamping sleeve 444 .

[0080] In the above implementation, the clamping claw 441 is configured as two half claws 4411 , which not only facilitates the guide cable 1 to be located between the two half claws 4411 , but also allows the clamping sleeve 444 to be firmly clamped together with the guide cable 1 .

[0081] Optionally, the clamping claw 441 is a structural member capable of plastic deformation.

[0082] In the above implementation, the clamping claw 441 is configured as a plastically deformable structural member. This ensures close contact between the clamping claw 441 and the guide cable 1, while increasing friction between the two and preventing relative sliding. Furthermore, the clamping claw 441 is configured as a plastically deformable structural member. After being deformed by the clamping sleeve 444, it can be further tightly clamped to the guide cable 1.

[0083] In this embodiment, when the inspection vehicle 4 is moving, if it encounters the corner guide wheel 21 or the driving wheel 31 located at the vertex of the polygon where the guide cable 1 is located, as long as the width and diameter of the cable groove in the axial direction on the outer periphery of the corner guide wheel 21 or the driving wheel 31 are set larger, the clamping head 44 will follow the linear guide cable 1 and smoothly pass over the corner guide wheel 21 or the driving wheel 31.

[0084] Because when the diameter of the corner guide wheel 21 or the driving wheel 31 is large, when the speed of the inspection vehicle 4 and the guide cable 1 is constant, the relative angle turned in the same time will be much smaller, making it easier to turn.

[0085] The width of the cable groove of the corner guide wheel 21 or the driving wheel 31 is set larger. When the clamping head 44 of the corner guide wheel 21 or the driving wheel 31 follows the linear guide cable 1 over the corner guide wheel 21 or the driving wheel 31, the clamping head 44 will be located in the cable groove of the corner guide wheel 21 or the driving wheel 31 and will not separate from the corner guide wheel 21 or the driving wheel 31, thereby ensuring that the inspection vehicle 4 can still smoothly cross the corner guide wheel 21 or the driving wheel 31.

[0086] For example, the maximum dimension of the outer diameter of the clamping head 44 is not greater than the width of the cable groove of the corner guide wheel 21 or the driving wheel 31 , and the difference between the two is 0-10 mm.

[0087] In this embodiment, the width of the cable groove of the corner guide wheel 21 or the driving wheel 31 is generally 30-50 mm. The diameter of the corner guide wheel 21 or the driving wheel 31 is 500-600 mm. The maximum outer diameter of the clamping head 44 does not exceed 50 mm.

[0088] See again Figure 1 and Figure 3Optionally, the monitoring device 45 in the inspection vehicle 4 is located at the bottom of the vehicle body 41 and is connected to the vehicle body 41. The monitoring device 45 includes a telescopic rod 451 and a camera 452. One end of the telescopic rod 451 is connected to the bottom of the vehicle body 41, and the other end of the telescopic rod 451 is connected to the camera 452. The telescopic rod 451 can be extended and retracted from the top to the bottom of the vehicle body 41.

[0089] In the above implementation, the monitoring device 45 is used to monitor in real time whether the equipment to be inspected and the surrounding environment are abnormal.

[0090] The monitoring device 45 is configured as a telescopic rod 451 and a camera 452. The camera 452 can be connected to the vehicle body 41 via the telescopic rod 451. Moreover, the telescopic rod 451 is configured to extend from the top to the bottom of the vehicle body 41. The length of the telescopic rod 451 can be flexibly adjusted, thereby adjusting the observation angle of the camera 452, so as to flexibly position the monitoring position of the camera 452.

[0091] In this embodiment, the telescopic rod 451 is an electric telescopic rod, which is controlled by a remote control. The electric telescopic rod is a three-stage telescopic rod, that is, the telescopic rod 451 is formed by three rods that are sequentially sleeved together.

[0092] In other examples, the telescopic rod 451 may also be replaced by other structures, such as an electric telescopic cylinder, etc.

[0093] Optionally, the inspection vehicle 4 further includes an alarm device 46, which is located at the bottom of the vehicle body 41 and spaced apart from the monitoring device 45. The alarm device 46 is connected to the bottom of the vehicle body 41 and is electrically connected to the monitoring device 45.

[0094] When the monitoring device 45 captures an abnormal situation, the alarm device 46 is triggered to start, and the alarm device 46 emits a warning sound to remind the staff to deal with the abnormality in time.

[0095] In the present embodiment, the alarm device 46 can be an alarm with a light prompt. After the alarm device 46 is started, the alarm device 46 sends an alarm reminder sound and a light flashes to provide a warning.

[0096] The following briefly introduces the working process of the inspection system provided by the embodiment of the present disclosure:

[0097] First, the guide cable 1 in the inspection system is arranged near the equipment to be inspected (generally placed on the top of the equipment to be inspected) through the support component 2 and the drive component 3, and the support component 2 and the drive component 3 are fixed on the top of the equipment accordingly.

[0098] Next, the inspection vehicle 4 is clamped to the guide cable 1 using the clamping head 44. Next, the drive motor 32 in the drive assembly 3 is activated to drive the drive wheel 31 in forward or reverse rotation. This forward or reverse rotation of the drive wheel 31 propels the guide cable 1 forward or backward. Once the guide cable 1 is in motion, it moves with the inspection vehicle 4. As the inspection vehicle 4 moves, the monitoring device 45 on the vehicle monitors the equipment being inspected and the surrounding environment. If the monitoring device 45 detects an anomaly, the alarm device 46 activates and sounds an alert.

[0099] The inspection system provided by the embodiment of the present disclosure is not only simple in structure, but also can be repeatedly disassembled and modified. Combined with the characteristics of the guide cable 1 that are easy to bend and guide, the workload and the number of accessories during outfitting are greatly reduced. The inspection vehicle 4 can be hoisted onto the guide cable 1 as a whole. In addition, the inspection system can reduce the cost of guide rail layout materials and installation time by using the guide cable 1 as the moving path of the inspection vehicle 4. At the same time, the inspection vehicle 4 does not need to have its own power supply, which greatly reduces the weight of the inspection vehicle 4, and more operation detection components can be arranged on a vehicle body of the same specification and weight.

[0100] Moreover, by configuring the support assembly 2 with three corner guide wheels 21 and other structures, the inspection vehicle 4 can be guided at a large angle. In addition, the guide cable 1 is designed as a loop, that is, the inspection route is in the shape of a U-shape, which effectively increases the inspection efficiency, avoids taking a long route and making a backtrack, and improves the inspection efficiency.

[0101] The above description is merely an optional embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the scope of protection of the present disclosure.
