Description

Technical Field

[0001] The present disclosure belongs to the field of automatic inspection technology, and in particular relates to a track inspection device. Background Art

[0002] When large equipment is working, in order to prevent accidents, regular inspections of the equipment's environment and operating status are generally carried out using inspection equipment, so as to discover hidden dangers early and eliminate them.

[0003] In related technologies, inspection equipment typically consists of a track mounted around or on top of the equipment being inspected and an inspection vehicle. The vehicle has two sets of wheels at its base. Each wheel is located on a track and moves along the track. By controlling the speed of the two wheels at different speeds, the vehicle can be turned.

[0004] However, when turning by controlling the speed of the two wheels to achieve a turn, the turning radius is determined by the speed difference between the two wheels, resulting in a limited turning angle. Furthermore, if the inspection vehicle travels along a track with a sharp curve, the large speed difference between the two wheels can easily cause it to roll over, hindering inspection work. Furthermore, the above-mentioned inspection vehicle requires two tracks corresponding to the two wheels when in operation, which increases costs. Summary of the Invention

[0033] 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.

[0034] The present disclosure provides a track inspection device, such as Figure 1 As shown, the track inspection equipment includes a track 1 and an inspection vehicle 2. One side of the track 1 has a U-shaped groove 10 comprising a bottom wall 101, a top wall 102, and side walls 103. The U-shaped groove 10 extends in the same direction as the length of the track 1. The bottom wall 101 and top wall 102 of the U-shaped groove 10 are located on opposite sides of the side wall 103 of the U-shaped groove 10 and are both connected to the side wall 103 of the U-shaped groove 10.

[0035] The inspection vehicle 2 includes a vehicle body 21, a running wheel assembly 22, a drive unit 23, and a guide wheel assembly 24. The running wheel assembly 22 is located in the U-shaped groove 10 and includes running wheels 221 rotatably connected to the vehicle body 21. The running wheels 221 are configured to run along the bottom wall 101 of the U-shaped groove 10. The drive unit 23 is connected to the vehicle body 21 and to the running wheels 221 to drive the running wheels 221 to rotate.

[0036] The guide wheel assembly 24 is located in the U-shaped groove 10. The guide wheel assembly 24 includes a guide wheel 240 rotatably connected to the vehicle body 21. The guide wheel 240 is configured to move along the side wall 103 of the U-shaped groove 10. The rotation axis of the guide wheel 240 is perpendicular to the rotation axis of the walking wheel 221.

[0037] When the track inspection equipment provided by the embodiment of the present disclosure is in use, since the track inspection equipment includes a track 1 and an inspection vehicle 2, and the track 1 has a U-shaped groove 10, the track 1 can provide an inspection route for the inspection vehicle 2, and the U-shaped groove 10 can provide a limit for the inspection vehicle 2 when it is moving, thereby preventing the inspection vehicle 2 from leaving the track 1.

[0038] Since the inspection vehicle 2 is a structure defined by the vehicle body 21, the running wheel assembly 22, the drive unit 23, and the guide wheel assembly 24, the vehicle body 21 can provide a mounting base for the running wheel assembly 22, the drive unit 23, and the guide wheel assembly 24. Simultaneously, the driving unit 23 drives the running wheel 221 to rotate, allowing the running wheel 221 to move along the bottom wall 101 of the track 1 while rotating, thereby enabling the inspection vehicle 2 to move along the track 1.

[0039] Moreover, since the guide wheel assembly 24 is located in the U-shaped groove 10, and the guide wheel 240 in the guide wheel assembly 24 can move along the side wall 103 of the U-shaped groove 10, when there is a curved section in the track 1, the setting of the guide wheel 240 can guide the inspection vehicle 2 to turn, so that the inspection vehicle 2 can still fit together with the track 1 when passing through the curved section of the track 1, so that the inspection vehicle 2 can pass through the curved section smoothly and avoid the inspection vehicle 2 from rolling over.

[0040] Furthermore, since only one track 1 is required, the cost can be greatly reduced.

[0041] Continue to see Figure 1 Optionally, the track 1 includes a top plate 11, a bottom plate 12, and side plates 13. The top plate 11 and the bottom plate 12 are arranged opposite each other, and the side plates 13 are located between the top plate 11 and the bottom plate 12. The side plates 13 are connected to the top plate 11 and the bottom plate 12 respectively and define a U-shaped groove 10. The plate surface of the side plates 13 is the side wall 103 of the U-shaped groove 10, and the top surface of the bottom plate 12 is the bottom wall 101 of the U-shaped groove 10. The bottom surface of the top plate 11 is the top wall 102 of the U-shaped groove 10.

[0042] In the above implementation, the track 1 is configured as described above, which allows the track 1 to simply define the U-shaped groove 10. Furthermore, the guide wheel assembly 24 can be in contact with only one sidewall of the U-shaped groove 10, so that when the track 1 bends, only one sidewall bends, reducing the difficulty of arranging the guide wheel assembly 24 and greatly improving the guiding efficiency of the guide wheel assembly 24.

[0043] Continue to see Figure 1 Optionally, at least one section of the bottom plate 12 is an inclined section. The angle between the inclined section and the horizontal plane is greater than 0° and less than 90°. That is, along the movement direction of the inspection vehicle 2, the distance between the inclined section and the top plate 11 gradually decreases, or both the inclined section and the top plate 11 are inclined upward.

[0044] The track 1 further includes a rack 14 , which is located on a side of the inclined section away from the top plate 11 and is connected to the inclined section. The length direction of the rack 14 is the same as the length direction of the inclined section.

[0045] Figure 2 for Figure 1 The structural diagram of the inspection vehicle in the figure is as follows: Figure 3 for Figure 2 Right view, combined with Figure 2 and Figure 3 The driving unit 23 includes a power structure 231 and a first gear 232 . The power structure 231 is connected to the first gear 232 to drive the first gear 232 to rotate. The first gear 232 is engaged with the rack 14 .

[0046] In the above implementation, the power structure 231 provides power to the first gear 232, enabling the first gear 232 to rotate. The first gear 232 meshes with the rack 14, so as the first gear 232 rotates, it meshes with the rack 14. This further increases the power of the inspection vehicle through the first gear 232 and the rack 14, allowing the inspection vehicle to move smoothly along the track 1, even when encountering steep inclines.

[0047] That is, through the cooperation between the first gear 232 and the rack 14 , the inspection vehicle 2 can be lifted, thereby easily passing through the inclined section of the track 1 .

[0048] In the embodiment of the present disclosure, there can be multiple racks 14 , and the multiple racks 14 are arranged at intervals. Each rack 14 is located at an inclined section of the track 1 .

[0049] When the rack 14 is not provided in the track 1 , the first gear 232 is spaced apart from the track 1 , and there is no interference between the first gear 232 and the track 1 .

[0050] In other examples, when the first gear 232 is not provided in the drive unit 23, at this time, if the inspection vehicle 2 needs to travel on a track 1 with a slope, in order to improve the climbing ability of the inspection vehicle 2, the output torque of the power structure 231 can be increased, or an anti-slip coating can be added to the bottom wall of the inclined section of the track 1, etc., so as to increase the friction between the walking wheel 221 and the bottom wall 101.

[0051] In the disclosed embodiment, the top plate 11, bottom plate 12, and side plates 13 are all flat plate-shaped structural members. The track 1 is an integrally cast structural member. This increases the structural strength of the track 1 and extends its service life.

[0052] Continue to combine Figure 3Optionally, there are two U-shaped grooves 10, the top walls 102 of the two U-shaped grooves 10 are located in the same plane, the bottom walls 101 of the two U-shaped grooves 10 are located in the same plane, and the two U-shaped grooves 10 are symmetrically arranged on opposite sides of the track 1. That is, the two U-shaped grooves 10 are respectively located on two opposite plate surfaces of the side plate 13.

[0053] Figure 4 for Figure 2 Schematic diagram after rotating 180°, combined with Figure 4 The guide wheel assembly 24 includes multiple guide wheel groups, which are arranged in pairs, and multiple pairs of guide wheel groups are arranged at intervals along the length direction of the track 1, and the two guide wheel groups in each pair of guide wheel groups are respectively located in two U-shaped grooves 10.

[0054] In other words, the guide wheels are arranged in mirror images in the two U-shaped grooves 10. This increases the contact area between the guide wheel assembly 24 and the track 1, further improving the guiding effect of the guide wheel assembly 24. Furthermore, when the track 1 bends, whether to the left or right relative to the forward direction of the inspection vehicle 2, one guide wheel 240 in the paired guide wheel assembly closely fits against the side plate 13 of the track 1, thereby guiding the inspection vehicle 2 through the turn.

[0055] Combine Figure 3 and Figure 4 Exemplarily, each guide wheel group includes two guide wheels 240, and the two guide wheels 240 are arranged at intervals along their own rotation axis, and one of the guide wheels 240 is located on the side wall 103 close to the top wall 102, and the other guide wheel 240 is located on the side wall 103 close to the bottom wall 101.

[0056] In the above implementation, by providing two guide wheels 240 in the guide wheel assembly 24 , the contact area between the guide wheel assembly 24 and the track 1 can be further increased, thereby improving the guiding efficiency of the guide wheel assembly 24 .

[0057] In other examples, the number of guide wheels 240 may be other numbers, such as three.

[0058] Combine Figure 1 For example, the U-shaped groove 10 of the track 1 can also be one, and the opening of the U-shaped groove 10 is located on the inner side of the arc of the curved section of the track 1, that is, Figure 1 The track 1 shown in FIG has only the U-shaped groove 10 on the right side. In this way, when the inspection vehicle 2 turns, the side panels 13 can limit the guide wheels 240, thereby applying inward pressure to the guide wheels 240, ensuring that the guide wheels 240 can always move along the side walls 103 of the U-shaped groove 10, thereby preventing the inspection vehicle 2 from deviating from the track 1.

[0059] When there is only one U-shaped groove 10, the guide wheel assembly 24 also includes multiple guide wheel groups. The multiple guide wheel groups are spaced apart along the length of the track 1. This can further increase the contact area between the guide wheel assembly 24 and the track 1, thereby further improving the guiding effect of the guide wheel assembly 24.

[0060] Figure 5 for Figure 4 Right view, combined with Figure 5 Optionally, the guide wheel assembly 24 further includes a guide seat 241 , which is connected to the top of the vehicle body 21 .

[0061] Figure 6 The structural diagram of the guide seat is shown in Figure 2. Figure 6 Optionally, the guide seat 241 includes a guide pillar 2411 , a guide elastic member 2412 and a guide mounting plate 2413 .

[0062] One end of the guide pillar 2411 is connected to the vehicle body 21 , and the other end is connected to the guide mounting plate 2413 . The guide mounting plate 2413 can move relative to the guide pillar 2411 . The length direction of the guide pillar 2411 is the same as the direction of the rotation axis of the walking wheel assembly 22 .

[0063] Each guide elastic member 2412 is sleeved outside the guide pillar 2411 , and two ends thereof respectively abut against the guide pillar 2411 and the guide mounting plate 2413 . Each guide wheel 240 is rotatably connected to the guide mounting plate 2413 .

[0064] In the above implementation, the guide pillars 2411 provide a mounting base for the guide mounting plate 2413, which in turn provides a mounting base for the guide wheels 240. The guide elastic members 2412 flexibly connect the vehicle body 21 to the guide mounting plate 2413. This allows the guide elastic members 2412 to support and cushion the guide mounting plate 2413 when the vehicle body 21 sways, ensuring that the guide wheels 240 maintain effective contact with the side panels 13 of the track 1.

[0065] In this embodiment, there are multiple guide posts 2411 and multiple guide elastic members 2412. The multiple guide elastic members 2412 are arranged in a one-to-one correspondence with the multiple guide posts 2411. This allows the multiple guide elastic members 2412 to further enhance the guide seat 241's shock absorption properties, ensuring that the guide wheel 240 maintains effective contact with the side plate 13 of the track 1.

[0066] Figure 7 for Figure 2 The schematic diagram of the structure on the left side of the middle part, combined with Figure 7In this embodiment, in order to enable the two guide wheels 240 in the same guide wheel assembly 24 to move independently, the guide mounting plate 2413 includes two first L-shaped plates arranged at intervals. The two first L-shaped plates correspond one-to-one to the two guide wheels 240, and each guide wheel 240 is rotatably mounted on the horizontal plate surface of the corresponding first L-shaped plate. The vertical plate surface of the first L-shaped plate is sleeved outside the guide pillar 2411 and is fixed to the guide pillar 2411 by fasteners such as bolts. The first L-shaped plate is connected to the two guide pillars 2411 in a corresponding manner, which can ensure the stability of the first L-shaped plate.

[0067] In this embodiment, there are four guide wheel groups.

[0068] Figure 8 for Figure 2 The schematic diagram of the structure on the right side of the middle part, combined with Figure 8 Optionally, the inspection vehicle 2 further includes an auxiliary wheel assembly 25 , which is located outside the bottom of the track 1 .

[0069] That is, the auxiliary wheel assembly 25 is located on the side of the bottom plate 12 away from the top plate 11. The auxiliary wheel assembly 25 includes auxiliary wheels 250 rotatably connected to the vehicle body 21. The auxiliary wheels 250 can rotate relative to the track 1 and move along the bottom surface of the track 1 while rotating. The rotation axis of the auxiliary wheel assembly 25 is parallel to the rotation axis of the running wheel 221.

[0070] In the above implementation, the auxiliary wheels 250 are used to further increase the contact area of ​​the inspection vehicle 2 when it moves relative to the track 1 , thereby improving the movement stability of the inspection vehicle 2 .

[0071] Optionally, the auxiliary wheel assembly 25 includes multiple auxiliary wheel groups, which are arranged in pairs, and the multiple pairs of auxiliary wheel groups are spaced apart along the length of the track 1. The two auxiliary wheels 250 in the two auxiliary wheel groups of each pair of auxiliary wheel groups are spaced apart along the rotation axis of the auxiliary wheels 250. This can further increase the stability of the inspection vehicle 2.

[0072] Figure 9 for Figure 8 The left view, combined with Figure 9 Optionally, the auxiliary wheel assembly further includes an auxiliary seat 251, which is connected to the top of the vehicle body 21. The auxiliary wheel 250 is rotatably connected to the auxiliary seat 251, and the auxiliary wheel 250 contacts the bottom wall 101 of the U-shaped groove 10 (that is, the top surface of the bottom plate 12).

[0073] In the above implementation, the auxiliary seat 251 is used to provide a mounting base for the auxiliary wheels 250. The auxiliary wheels 250 are used to contact the bottom plate 12 of the track 1 to further increase the contact area between the inspection vehicle 2 and the track 1, so that the inspection vehicle 2 can only run close to the track 1, thereby improving the stability of the inspection vehicle 2.

[0074] In the disclosed embodiment, the auxiliary seat 251 has the same structure as the guide seat 241. The auxiliary seat 251 includes an auxiliary support post 2511, an auxiliary elastic member 2512, and an auxiliary mounting plate 2513. One end of the auxiliary support post 2511 is connected to the vehicle body 21, and the other end is slidably inserted into the auxiliary mounting plate 2513. The length direction of the auxiliary support post 2511 is the same as the rotation axis direction of the guide wheel assembly 24. The auxiliary elastic member 2512 is sleeved over the corresponding auxiliary support post 2511, and its two ends respectively abut against the auxiliary support post 2511 and the auxiliary mounting plate 2513. Each auxiliary wheel 250 is rotatably connected to the corresponding auxiliary mounting plate 2513.

[0075] In the above implementation, the auxiliary support pillars 2511 provide a mounting base for the auxiliary mounting plate 2513, which in turn provides a mounting base for the auxiliary wheels 250. The auxiliary elastic members 2512 flexibly connect the vehicle body 21 to the auxiliary mounting plate 2513. This allows the auxiliary elastic members 2512 to support and cushion the auxiliary mounting plate 2513 when the vehicle body 21 shakes, ensuring that the auxiliary wheels 250 maintain effective contact with the side panels 13 of the track 1.

[0076] In the disclosed embodiment, two auxiliary wheels 250 are provided in the same auxiliary wheel assembly, spaced apart along the extension direction of the track 1. To enable the two auxiliary wheels 250 in the same auxiliary wheel assembly to move independently, the auxiliary mounting plate 2513 includes two spaced apart second L-shaped plates. The two second L-shaped plates correspond one to each auxiliary wheel 250, and each auxiliary wheel 250 is rotatably mounted on the vertical surface of the corresponding second L-shaped plate. The horizontal surface of the second L-shaped plate is perpendicularly connected to the auxiliary support 2511.

[0077] Exemplarily, each auxiliary mounting plate 2513 is connected to two auxiliary pillars 2511. This can further improve the stability of the auxiliary mounting plate 2513.

[0078] In this embodiment, the auxiliary wheel set includes four pairs, namely eight auxiliary wheels 250 .

[0079] Figure 10 for Figure 4 The top view, combined with Figure 10In this embodiment, the inspection vehicle 2 further includes a rolling wheel assembly 28. The rolling wheel assembly 28 is spaced apart from the running wheel assembly 22 along the extension direction of the track 1 and is located within the U-shaped groove 10. The rolling wheel assembly 28 includes at least one supporting rolling wheel 281 rotatably connected to the vehicle body 21. The supporting rolling wheel 281 travels along the bottom wall 101 of the U-shaped groove 10, and the rotation axis of the supporting rolling wheel 281 is parallel to the rotation axis of the running wheel 221. The supporting rolling wheel 281 increases the contact area between the inspection vehicle 2 and the track 1, thereby improving stability.

[0080] Combine Figure 4 and Figure 7 In the embodiment of the present disclosure, when there are two U-shaped grooves 10, the running wheel assembly 22 includes two running wheels 221 corresponding to the two U-shaped grooves 10 one by one. The two running wheels 221 are coaxial and spaced apart, and the rotating shaft of each running wheel 221 is rotatably connected to the vehicle body 21. Each running wheel 221 is located in the corresponding U-shaped groove 10. One of the two running wheels 221 is transmission-connected to the drive unit 23. In this way, the contact area between the running wheel assembly 22 and the track 1 can be increased by arranging two running wheels 221, so that the inspection vehicle 2 can stably run along the track 1.

[0081] Optionally, the power structure 231 includes a motor 2310, a reducer 2311, a pulley assembly 2312, an intermediate shaft 2313, a second gear 2314, and a third gear 2315. The motor 2310 is coaxially connected to the reducer 2311. The pulley assembly 2312 is located at one end of the output shaft of the reducer 2311, and one pulley in the pulley assembly 2312 is coaxially connected to the output shaft of the reducer 2311. The other pulley in the pulley assembly 2312 is located to one side of the pulley connected to the reducer 2311. One end of the intermediate shaft 2313 is interference-fitted into the other pulley. The intermediate shaft 2313 is arranged parallel to the rotating shaft of the running wheel 221. The first gear 232 is interference-fitted onto the outside of the middle portion of the intermediate shaft 2313. The second gear 2314 and the third gear 2315 are located on opposite sides of the motor 2310 and the reducer 2311, respectively, along with the pulley assembly 2312. The second gear 2314 is interference-fitted around the intermediate shaft 2313 and meshes with the third gear 2315. The third gear 2315 is interference-fitted around the rotating shaft of one of the travel wheels 221.

[0082] In the above implementation, the power structure 231 is configured as described above, and the power structure 231 can drive the running wheels 221. During normal operation, the motor 2310 is first started, which drives the reducer 2311 to operate. The reducer 2311 drives the pulley assembly 2312 to rotate, thereby driving the intermediate shaft 2313 to rotate. The intermediate shaft 2313 rotates, which in turn drives the first gear 232, the second gear 2314, and the third gear 2315 to rotate. The rotation of the third gear 2315 then drives one of the running wheels 221 to rotate. In other words, by controlling the motor 2310 to rotate the reducer 2311 forward or reverse, the inspection vehicle 2 can move forward or backward. Furthermore, the second gear 2314 and the third gear 2315 are located on opposite sides of the pulley assembly 2312, respectively, balancing the center of gravity of the power structure 2311 while ensuring that the running wheels 221 and the first gear 232 rotate synchronously, thereby assisting the inspection vehicle 2 in climbing hills.

The third connecting plate 2123 and the fourth connecting plate 2124 are arranged parallel to each other and are both located between the first connecting plate 2121 and the second connecting plate 2122. The third connecting plate 2123 is affixed to and connected to the top of the housing 211 via screws. The fourth connecting plate 2124 is located on the side of the third connecting plate 2123 facing away from the housing 211. Opposite sides of the third connecting plate 2123 and the fourth connecting plate 2124 are connected to the first connecting plate 2121 and the second connecting plate 2122, respectively. This provides a mounting base for the guide wheel assembly via the first connecting plate 2121 and the second connecting plate 2122, while the fourth connecting plate 2124 provides a mounting base for the auxiliary wheel assembly.

[0087] In this embodiment, the interior of the box body 211 is hollow, which makes it easy to assemble power supply equipment for the inspection vehicle 2, such as a battery pack.

The rotating shaft of each supporting rolling wheel is rotatably connected to the first connecting plate 2121 and the second connecting plate 2122 of the second mounting bracket 2102. The guide pillars 2411 in the guide wheel assembly 24 are respectively connected to the first connecting plate 2121 and the second connecting plate 2122 of the mounting bracket 212 in which they are located via bolts or other fasteners. The auxiliary pillars 2511 in the auxiliary wheel assembly 25 are respectively connected to the fourth connecting plate 2124 of the mounting bracket 212 in which they are located via bolts or other fasteners.

[0089] Combine Figure 10 In order to save space and facilitate the installation of the track inspection equipment, in the embodiment of the present disclosure, the first mounting bracket 2101 and the second mounting bracket 2102 are symmetrical about the plane ( Figure 10The guide wheel assembly connected to the first mounting bracket 2101 and the guide wheel assembly connected to the second mounting bracket 2102 are also arranged symmetrically about the symmetry plane a). The auxiliary wheel assembly connected to the first mounting bracket 2101 and the auxiliary wheel assembly connected to the second mounting bracket 2102 are also arranged symmetrically about the symmetry plane. The rolling wheel assembly 28 connected to the first mounting bracket 2101 and the running wheel assembly 22 connected to the second mounting bracket 2102 are also arranged symmetrically about the symmetry plane. The symmetry plane is perpendicular to the extension direction of the track 1.

[0090] For the same mounting bracket 212 , the guide wheel assembly is located on the side of the traveling wheel assembly 22 or the rolling wheel assembly 28 facing the symmetry plane, and the auxiliary wheel assembly is located below the guide wheel assembly and the traveling wheel assembly 22 or below the guide wheel assembly and the rolling wheel assembly 28 .

[0091] In the embodiment of the present disclosure, in order to further reduce the weight of the inspection vehicle 2 , at least one weight-reducing hole is provided in the first connecting plate 2121 and the second connecting plate 2122 .

[0092] Combine Figure 2 Optionally, the inspection vehicle 2 further includes a monitor 26 , which is located at the front side of the vehicle body 21 in the traveling direction and is connected to the vehicle body 21 .

[0094] In the embodiment of the present disclosure, the monitor 26 may be a camera.

[0095] Optionally, the inspection vehicle 2 further includes an alarm 27 , which is located at the bottom of the vehicle body 21 and connected to the vehicle body 21 . The alarm 27 is electrically connected to the monitor 26 .

[0096] When the monitor 26 captures an abnormal situation, the alarm 27 is triggered to start, and the alarm 27 emits a warning sound to remind the staff to deal with the abnormality in time.

[0097] In the embodiment of the present disclosure, the alarm 27 can be an alarm with a light prompt. After the alarm 27 is activated, the alarm 27 simultaneously emits an alarm reminder sound and a light flashes to provide a warning.

[0098] The following briefly introduces the working process of the track inspection device provided by the embodiment of the present disclosure:

[0099] During normal operation of the track inspection equipment, first, the reducer 2311 is started, and the reducer 2311 drives the intermediate shaft 2313 to rotate under the transmission of the pulley set 2312. After the intermediate shaft 2313 rotates, the first gear 232 is driven to rotate, and the first gear 232 can mesh with the rack 14 and move along the rack 14.

[0100] At the same time, second gear 2314 also rotates along with intermediate shaft 2313. The rotation of second gear 2314 drives third gear 2315 to rotate as well. The rotation of third gear 2315 drives running wheels 221, allowing inspection vehicle 2 to travel along track 1. The coordination between first gear 232 and rack 14 enables inspection vehicle 2 to climb hills.

[0101] During the movement of the inspection vehicle 2, the guide wheel 240 in the guide wheel assembly 24 rotates, and the guide wheel 240 runs close to the side plate 13 of the track 1. When the inspection vehicle 2 encounters a large curved section during running, it can effectively contact the track 1.
