Description

Technical Field

[0001] The present invention relates to the technical field of inspection equipment, and in particular to inspection equipment capable of inspecting areas such as factories and tunnels, and in particular to a locking device, a guide rail of a hanging rail-type inspection robot, and a guide rail locking method. Background Art

[0002] With urban development, the use of urban utility corridors is increasing. However, since utility corridors are semi-enclosed spaces with numerous internal wiring, manual inspections are quite dangerous. To ensure the safety of inspectors, rail-mounted inspection robots have emerged. Due to the complexity of urban utility corridors, when there are large turning angles or height differences between corridors, rail-mounted inspection robots need to be relocated using a track-changing device.

[0003] However, during the track changing process of the existing hanging rail inspection robot, the fixed guide rail and the movable guide rail are prone to not being locked in place, resulting in an excessively large gap between the fixed guide rail and the movable guide rail, which in turn causes the walking wheels of the hanging rail inspection robot to get stuck at the guide rail connection, or even the hanging rail inspection robot to fall off from the guide rail connection. Summary of the Invention

[0004] In order to solve the problem that the existing rail-type inspection robot is not locked in place when changing tracks, resulting in the walking wheels of the rail-type inspection robot being stuck at the guide rail connection or the rail-type inspection robot falling off from the guide rail connection, the present invention provides a locking device, including: a first locking device, provided with a first locking member; a second locking device, detachably arranged on one side of the first locking device, provided with a second locking member; at least one blocking part, arranged on the second locking device, and extending out of the second locking device; wherein the locking member is transmission-connected to the blocking part, and when the first locking member and the second locking member are assembled, the blocking part retracts into the second locking device.

[0005] The technical effect achieved after adopting this technical solution is: since the second locking device is provided with a blocking part extending out of the second locking device, and only when the first locking member and the second locking member are locked in place, the blocking part will retreat into the second locking device, so that the rail-type inspection robot can move forward normally; therefore, when the first locking device and the second locking device are not locked in place, the blocking part can prevent the rail-type inspection robot from continuing to move forward, thereby preventing the rail-type inspection robot from traveling to the connection between the first locking device and the second locking device that is not locked in place, and further preventing the rail-type inspection robot from getting stuck in the connection between the first locking device and the second locking device or the rail-type inspection robot from falling from the connection between the first locking device and the second locking device.

[0006] In this embodiment, the first locking member is a locking shaft, and the second locking member is a locking hole. The locking shaft can extend into or out of the locking hole to achieve a detachable connection between the first locking device and the second locking device.

[0007] The technical effect achieved after adopting this technical solution is: since the first locking member is a locking shaft and the second locking member is a locking hole, the first locking device and the second locking device can be detachably connected by extending the locking shaft into or out of the locking hole. Compared with other connection methods, the structural design is simpler and the operation is more convenient.

[0008] In this embodiment, the first locking device includes: a transmission part connected to the locking shaft; and a driving part provided on one side of the transmission part and drivingly connected to the transmission part.

[0009] The technical effect achieved after adopting this technical solution is: the driving part can convert electrical energy into mechanical energy for outputting driving force to drive the locking shaft to extend into or exit the locking hole, thereby realizing locking or unlocking between the first locking device and the second tightening device; the transmission part is used to transmit the driving force output by the driving part to the locking shaft, and convert the rotational motion of the driving part into linear motion of the locking shaft.

[0010] In this embodiment, the transmission part includes: a crank assembly, which is arranged at the output end of the driving part and is connected to the driving part; a connecting rod assembly, which is arranged on the side of the crank assembly away from the driving part and is connected to the crank assembly; wherein the locking shaft is arranged on the side of the connecting rod assembly away from the crank assembly.

[0011] The technical effect achieved after adopting this technical solution is: the transmission part is set to cooperate with the crank assembly and the connecting rod assembly, and the crank assembly can convert the rotational motion output by the driving part into the linear motion of the connecting rod assembly, thereby driving the locking shaft to extend into or exit the locking hole; compared with other transmission structures, the mechanical transmission method of the crank-connecting rod assembly is adopted, the structural design is simple, and the transmission cost is low.

[0012] In this embodiment, the second locking device includes: a mounting portion with a mounting space provided therein; and a blocking accommodating groove, which is opened on one side of the mounting portion; wherein the blocking portion is rotatably provided on the mounting portion, and the blocking portion can be screwed into or out of the mounting space through the blocking accommodating groove.

[0013] The technical effect achieved after adopting this technical solution is: since the blocking part is rotatably arranged on the mounting part, and a blocking accommodating groove is opened on the mounting part, when the first locking device and the second locking device are not locked, the blocking part is affected by gravity and can be rotated out of the mounting space from the blocking accommodating groove of the mounting part, hindering the hanging rail type inspection robot from continuing to move forward, thereby avoiding the problems of the hanging rail type inspection robot's walking wheels being stuck at the connection between the first locking device and the second locking device when the hanging rail type inspection robot travels to the connection between the first locking device and the second locking device that are not locked in place, or the hanging rail type inspection robot falling from the connection between the first locking device and the second locking device.

[0014] In this embodiment, the second locking device further includes: a blocking transmission part, which is arranged in the installation space, one end of which is transmission-connected to the blocking part, and the other end of which is connected to the second locking member.

[0015] The technical effect achieved after adopting this technical solution is: since a blocking transmission part is provided in the installation space of the second locking device, when the locking shaft extends into the locking hole, the blocking transmission part can drive the blocking transmission part connected to it to rotate. When the blocking transmission part is just completely screwed into the installation space, it means that the locking shaft and the locking hole have been locked in place, and the hanging rail inspection robot can be placed to continue moving forward.

[0016] In this embodiment, the blocking transmission part includes: a sliding component, which is slidably arranged on the mounting part, and one end of which is arranged in the locking hole; a rotating component, which is rotatably arranged on the mounting part, and the gear engages with the sliding component; wherein, the sliding component can rotate the blocking part into the mounting space through the rotating component.

[0017] The technical effect achieved after adopting this technical solution is: since the blocking transmission part consists of a sliding component and a rotating component, during the operation of the blocking transmission part, the sliding component can transmit the linear motion of the locking shaft to the rotating component, and the rotating component can convert the linear motion transmitted by the sliding component into rotational motion to drive the blocking part to rotate in or out of the installation space, so that it can be judged whether the first locking device and the second locking device are locked in place according to the position of the blocking part.

[0018] In this embodiment, there are two blocking parts, and the sliding component is sandwiched between the two blocking parts.

[0019] The technical effect achieved after adopting this technical solution is: since the locking device is provided with two blocking parts, it can block the walking wheels on both sides of the hanging rail inspection robot at the same time, further improving the blocking effect of the blocking part on the hanging rail inspection robot; the sliding component is arranged between the two blocking parts, compared with being arranged on the same side, the structural design is more reasonable and the transmission efficiency is also higher.

[0020] An embodiment of the present invention provides a guide rail for a hanging rail-type inspection robot, comprising a locking device as described in any of the previous embodiments, at least one fixed guide rail connected to the first locking device; and at least one movable guide rail connected to the second locking device; wherein the movable guide rail is detachably connected to the fixed guide rail through the locking device.

[0021] An embodiment of the present invention provides a guide rail locking method, which uses the guide rail of the hanging rail inspection robot as described above. The guide rail locking method includes: setting the movable guide rail on one side of the fixed guide rail, locking the first locking member and the second locking member to drive the blocking part to move, and when the blocking part retracts into the second locking device, the locking of the movable guide rail and the fixed guide rail is completed.

[0022] The technical effect achieved by adopting this technical solution is: whether the fixed guide rail and the movable guide rail are locked in place can be judged by whether the blocking part is retracted into the second locking device.

[0023] In summary, the above embodiments of the present application may have one or more of the following advantages or beneficial effects:

[0024] (1) Since the second locking device is provided with a blocking portion extending out of the second locking device, and the blocking portion will only retract into the second locking device when the first locking member and the second locking member are engaged, the rail-type inspection robot can move forward normally; therefore, when the first locking device and the second locking device are not locked in place, the blocking portion can prevent the rail-type inspection robot from continuing to move forward, thereby preventing the rail-type inspection robot from moving to the connection between the first locking device and the second locking device that is not locked in place, and further preventing the rail-type inspection robot from having its walking wheels stuck at the connection between the first locking device and the second locking device or the rail-type inspection robot from falling from the connection between the first locking device and the second locking device.

[0025] (2) Since the blocking portion is rotatably arranged on the mounting portion and a blocking accommodating groove is provided on the mounting portion, when the first locking device and the second locking device are not locked, the blocking portion is acted upon by gravity and can be rotated out of the mounting space from the blocking accommodating groove of the mounting portion, thereby preventing the hanging rail type inspection robot from continuing to move forward, thereby avoiding problems such as the hanging rail type inspection robot's walking wheels being stuck at the connection between the first locking device and the second locking device or the hanging rail type inspection robot falling from the connection between the first locking device and the second locking device when the hanging rail type inspection robot moves to the connection between the first locking device and the second locking device that are not locked in place.

[0026] (3) Since a blocking transmission part is provided in the installation space of the second locking device, when the locking shaft extends into the locking hole, the blocking transmission part can drive the blocking transmission part connected to it to rotate. When the blocking transmission part is just completely screwed into the installation space, it means that the locking shaft and the locking hole have been locked in place, and the hanging rail inspection robot can be placed to continue moving forward.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0037] [First embodiment]

[0038] See also Figure 1 , which is a structural diagram of a locking device 100 provided by the first embodiment of the present invention. Figures 1 to 3 The locking device 100, for example, includes: a first locking device 10, a second locking device 20, and a blocking portion 24. The first locking device 10 includes a first locking member; the second locking device 20 is detachably mounted on one side of the first locking device 10 and includes a second locking member 28; at least one blocking portion 24 is mounted on the second locking device 20 and extends out of the second locking device 20; specifically, when the first locking member and the second locking member 28 are assembled, the blocking portion 24 retracts into the second locking device 20.

[0039] Since the second locking device 20 is provided with a blocking portion 24 that extends out of the second locking device 20, it is possible to determine whether the first locking device 10 and the second locking device 20 are locked in place based on the position of the blocking portion 24, that is, whether the blocking portion 24 has retracted into the second locking device 20. If the first locking device 10 and the second locking device 20 are not locked or not locked in place, the blocking portion 24 will extend out of the second locking device 20 due to the action of gravity, preventing the rail-type inspection robot from continuing to move forward, thereby preventing the rail-type inspection robot from traveling to the connection between the first locking device 10 and the second locking device 20 that is not locked in place, and further preventing the rail-type inspection robot from getting stuck in the connection between the first locking device 10 and the second locking device 20 or the rail-type inspection robot from falling from the connection between the first locking device 10 and the second locking device 20.

[0040] In one specific embodiment, the first locking member is a locking shaft 14; the second locking member 28 is provided with a locking hole 22, into which the locking shaft 14 can be inserted or withdrawn, thereby achieving a detachable connection between the first locking device 10 and the second locking device 20. Because the first locking member is the locking shaft 14 and the second locking member 28 is provided with a locking hole 22, the detachable connection between the first locking device 10 and the second locking device 20 can be achieved by inserting or withdrawing the locking shaft 14 into or from the locking hole 22. Compared to other connection methods, the structural design is simpler and the operation is more convenient.

[0041] Further, combined Figure 2 The first locking device 10, for example, includes: a locking mounting plate 11, a driving portion 12, a transmission portion 13, and a locking shaft 14. The driving portion 12, the transmission portion 13, and the locking shaft 14 are all arranged on the locking mounting plate 11; the transmission portion 13 is connected to the locking shaft 14; the driving portion 12 is arranged on one side of the transmission portion 13, driving the connected transmission portion 13; specifically, the driving portion 12 drives the connected locking shaft 14 through the transmission portion 13. For example, the driving portion 12 is a driving motor, which is used to convert electrical energy into mechanical energy, thereby driving the locking shaft 14 to extend into or exit the locking hole 22 through the transmission portion 13, so as to achieve locking or unlocking between the first locking device 10 and the second locking device 20; the transmission portion 13 is used to transmit the driving force output by the driving portion 12 to the locking shaft 14, and convert the rotational motion of the driving portion 12 into the linear motion of the locking shaft 14.

[0042] Furthermore, the transmission unit 13 includes, for example, a crank assembly 15 and a connecting rod assembly 16. The crank assembly 15 is disposed at the output end of the drive unit 12, and the drive unit 12 drives and connects to the crank assembly 15. The connecting rod assembly 16 is disposed on a side of the crank assembly 15 away from the drive unit 12 and is hingedly connected to the crank assembly 15. Specifically, the locking shaft 14 is disposed on the side of the connecting rod assembly 16 away from the crank assembly 15.

[0043] Further, combined Figures 3 to 5 The second locking device 20 includes, for example, a mounting portion 21 and a blocking groove 27. The mounting portion 21 has an interior with a mounting space, and the blocking groove 27 is formed on the mounting portion 21. The blocking portion 24 is rotatably disposed on the mounting portion 21, and the blocking portion can be screwed into or out of the second locking device 20 through the blocking groove 27.

[0044] In a specific embodiment, when the first locking device 10 and the second locking device 20 are not locked or not locked in place, the blocking portion 24 is extended from the blocking accommodating groove 27 by gravity to the second locking device 20, thereby preventing the rail-type inspection robot from continuing to move forward; during the locking process of the first locking device 10 and the second locking device 20, the locking shaft 14 can drive the blocking portion 24 to rotate in the direction close to the blocking accommodating groove 27. When the blocking portion 24 is screwed into the second locking device 20 from the blocking accommodating groove 27, the first locking device 10 and the second locking device 20 are locked in place.

[0045] Furthermore, the second locking device 20 further includes, for example, a blocking transmission portion 23 , which is disposed in the installation space, one end of which is in transmission connection with the blocking portion 24 , and the other end of which is connected to the second locking member 28 .

[0046] In a specific embodiment, when the locking shaft 14 extends into the locking hole 22 defined in the second locking member 28 , the blocking transmission portion 23 can be rotated toward the blocking receiving groove 27 so that the blocking transmission portion 23 is screwed into the second locking device 20 .

[0047] Furthermore, the blocking transmission part 23 includes, for example, a sliding assembly 25 and a rotating assembly 26. The sliding assembly 25 is rotatably mounted on the mounting part 21, with one end disposed in the locking hole 22; the rotating assembly 26 is rotatably mounted on the mounting part 21, and a gear meshes with the sliding assembly 25.

[0048] In a specific embodiment, a first mounting hole 211 is formed on the mounting portion 21, one end of the sliding component 25 extends into the locking hole 22 from the side of the second locking member 28 away from the locking shaft 14, and the other end of the sliding component 25 is arranged in the first mounting hole 211; a rotating shaft 261 is provided at both ends of the rotating component 26, a corresponding second mounting hole 212 is formed on the mounting portion 21, and the rotating shaft 261 is arranged in the second mounting hole 212; an engaging end face 251 is provided on the side of the sliding component 25 close to the rotating component 26, and an engaging gear 262 engaged with the engaging end face 251 is provided in the middle of the rotating component 26.

[0049] Combine Figure 5 When the locking shaft 14 extends into the locking hole 22, it can drive the sliding assembly 25 also provided in the locking hole 22 to slide in the direction away from the second locking member 28, thereby driving the rotating assembly 26 to rotate counterclockwise around the rotating shaft 261, and then driving the blocking portion 24 to rotate in the direction close to the blocking accommodating groove 27. When the blocking portion 24 is screwed into the mounting portion 21 from the blocking accommodating groove 27, the locking shaft 14 is fully extended into the locking hole 22, and the locking between the first locking device 10 and the second locking device 20 is completed.

[0050] Preferably, the second locking device 20 is provided with two blocking portions 24, with the sliding assembly 25 sandwiched between the two blocking portions 24. Specifically, the two blocking portions 24 are fixedly connected to either side of the rotating assembly 26, with the meshing gear 262 located between the two blocking portions 24. By providing two blocking portions 24, blocking can be provided on both sides of the second locking device 20, thereby enhancing the blocking effect of the blocking portions 24 on the rail-mounted inspection robot. Placing the sliding assembly 25 between the two blocking portions 24 provides a more rational structural design and higher transmission efficiency than placing it on the same side.

[0051] [Second embodiment]

[0052] The second embodiment of the present invention provides a guide rail 200 for a hanging rail type inspection robot. Figure 6 The guide rail 200 of the overhead inspection robot includes, for example, the locking device 100 provided in the first embodiment of the present invention, a fixed guide rail 210, and a movable guide rail 220. The first locking device 10 is disposed on the fixed guide rail 210, and the second locking device 20 is disposed on the movable guide rail 220. The movable guide rail 220 is detachably connected to the fixed guide rail 210 via the locking device 100.

[0053] In a specific embodiment, during the track changing process of the hanging rail type inspection robot, the hanging rail type inspection robot is set on the movable guide rail 220. First, the movable guide rail 220 and the hanging rail type inspection robot thereon are set on the side of the fixed guide rail 210 where the first locking device 10 is provided through the track changing device. At this time, the two blocking parts 24 are vertically arranged on both sides of the movable guide rail 220 under the action of gravity, blocking the hanging rail type inspection robot from continuing to move forward; then the locking shaft 14 is driven to extend into the locking hole 22. After the locking shaft 14 extends into the locking hole 22, the blocking part 24 can be driven by the blocking transmission part 23 to rotate in the direction close to the blocking accommodating groove 27. When the blocking part 24 is screwed into the second locking device 20, the locking shaft 14 is completely extended into the locking hole 22. The first locking device 10 and the second locking device 20 are locked in place, and the movable guide rail 220 and the fixed guide rail 210 are assembled; then the hanging rail type inspection robot moves from the movable guide rail 220 to the fixed guide rail 210 to complete the track changing.

[0054] Since a locking device 100 is provided between the fixed guide rail 210 and the movable guide rail 220, when the fixed guide rail 210 and the movable guide rail 220 are not locked in place, the blocking part 24 can prevent the hanging rail type inspection robot from continuing to move forward, thereby preventing the hanging rail type inspection robot from driving to the connection between the fixed guide rail 210 and the movable guide rail 220 that is not locked in place, and further preventing the hanging rail type inspection robot's walking wheels from getting stuck at the connection between the fixed guide rail 210 and the movable guide rail 220 or the hanging rail type inspection robot from falling from the connection between the fixed guide rail 210 and the movable guide rail 220.

[0055] [Third embodiment]

[0056] The third embodiment of the present invention provides a guide rail locking method, which uses the hanging rail type inspection robot guide rail 200 as described above. The guide rail locking method includes: setting the movable guide rail 220 on one side of the fixed guide rail 210, locking the first locking member and the second locking member 28 to drive the blocking part 24 to move, and when the blocking part 24 retreats to the second locking device 20, the locking of the movable guide rail 220 and the fixed guide rail 210 is completed.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
