DETAILED DESCRIPTION

[0040] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0041] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0042] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0043] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0044] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0045] First, the first direction, the second direction and the third direction mentioned in the embodiment of the present application are described in the attached drawings. Figure 1 and Figure 8 The marked directions. The first direction, the second direction and the third direction intersect each other.

[0046] like Figure 1-Figure 4As shown, according to the first aspect of an embodiment of the present application, a locking mechanism 100 is provided, comprising a first locking component 1 and a second locking component 2; the first locking component 1 comprises a rotatable first hook 11, and the first hook 11 can rotate around a first direction; the second locking component 2 comprises a second hook 21; the first hook 11 rotates around the first direction toward the direction close to the second hook 21, the first hook 11 and the second hook 21 are locked with each other, and the second locking component 2 can limit the first locking component 1 from moving along the second direction; the first hook 11 rotates around the first direction toward the direction away from the second hook 21, and the first hook 11 disengages from the second hook 21; the first direction intersects with the second direction.

[0047] The locking mechanism 100 provided in the embodiment of the present application is suitable for being set in a maintenance platform device to restrict the movement of the mobile platform 5 to prevent the mobile platform 5 from moving during maintenance. It is also suitable for other devices for restricting movement.

[0048] like Figure 1-Figure 4 As shown, the locking mechanism 100 includes a first locking assembly 1 and a second locking assembly 2. The first locking assembly 1 and the second locking assembly 2 are mounted on different components. When the first locking assembly 1 and the second locking assembly 2 are interlocked, the two components, on which the first locking assembly 1 and the second locking assembly 2 are mounted, cannot move relative to each other. The two components can be the mobile platform 5 and the device being inspected 6, respectively.

[0049] To further illustrate, the first locking assembly 1 includes a rotatable first hook 11 capable of rotating in a first direction; the second locking assembly 2 includes a second hook 21. When the first hook 11 rotates in the first direction and approaches the second hook 21, the first hook 11 and the second hook 21 interlock with each other, thereby restricting the first locking assembly 1 and the second locking assembly 2 from moving in the second direction. If the first locking assembly 1 and the second locking assembly 2 are respectively arranged on different components, the relative movement of the two components can be restricted. When the first hook 11 rotates in the first direction and moves away from the second hook 21, the first hook 11 disengages from the second hook 21, allowing the two components to move relative to each other.

[0050] In an optional embodiment, the first locking assembly 1 further includes a mounting seat 12 and a rotating shaft 13, the mounting seat 12 is connected to the first hook 11 via the rotating shaft 13, and the first hook 11 can rotate around the first direction via the rotating shaft 13; the axial direction of the rotating shaft 13 is the same as the first direction.

[0051] like Figure 1 and Figure 3As shown, the first locking assembly 1 includes a mounting seat 12 and a rotating shaft 13 , wherein the mounting seat 12 can provide mounting support for the first hook 11 .

[0052] In a specific embodiment, the rotating shaft 13 is rotatably connected to the mounting base 12, and the first hook 11 is fixedly connected to the rotating shaft 13. Specifically, the mounting base 12 has a bearing hole, and a bearing is disposed in the bearing hole. That is, the outer ring of the bearing is connected to the inner wall of the bearing hole, and the rotating shaft 13 is connected to the inner ring of the bearing. Therefore, the rotating shaft 13 can rotate relative to the mounting base 12. The axial direction of the rotating shaft 13 is the same as the first direction. Therefore, when the rotating shaft 13 rotates, it rotates about the axis in the first direction. The rotating shaft 13 is fixedly connected to the first hook 11, so the first hook 11 can also rotate about the axis in the first direction.

[0053] In another specific embodiment, the rotating shaft 13 is fixedly connected to the mounting seat 12, and the first hook 11 is rotatably connected to the rotating shaft 13; specifically, a bearing is provided on the first hook 11, and a bearing is provided in the bearing hole, that is, the outer ring of the bearing is connected to the inner wall of the bearing hole, and the rotating shaft 13 is connected to the inner ring of the bearing, so the first hook 11 can rotate relative to it; wherein the axial direction of the rotating shaft 13 is the same as the first direction, so the first hook 11 rotates around the axial direction of the rotating shaft 13 through the bearing, that is, the first hook 11 rotates around the first direction.

[0054] In an optional embodiment, the first hook 11 includes a limiting portion 111 and a hook portion 112, and the limiting portion 111 and the hook portion 112 are respectively located on both sides of the rotating shaft 13 along the second direction; the mounting seat 12 includes a connecting portion 121, and the connecting portion 121 is located below the limiting portion 111 in the third direction. The first hook 11 rotates around the first direction in a direction away from the second hook 21, and the limiting portion 111 can abut against the connecting portion 121; the third direction intersects with the first direction, and the third direction intersects with the second direction.

[0055] like Figure 1 As shown, the first hook 11 includes a limiting portion 111 and a hook portion 112; when the first hook 11 rotates around the first direction toward the direction away from the second hook 21, the hook portion 112 moves upward along the third direction, and the limiting portion 111 moves downward along the third direction. The connecting portion 121 of the mounting portion is located below the limiting portion 111 in the third direction. Therefore, when the limiting portion 111 abuts against the connecting portion 121, the first hook 11 cannot continue to rotate around the first direction toward the direction away from the second hook 21, thereby preventing the first hook 11 from rotating too much and being unable to rotate.

[0056] In an optional embodiment, the first locking assembly 1 further includes a first fixing seat 14 . A groove 141 is defined on the first fixing seat 14 . The connecting portion 121 is located in the groove 141 and connected to the first fixing seat 14 .

[0057] like Figure 1 and Figure 2 As shown, a groove 141 is provided on the first fixing seat 14, the length direction of the groove 141 is the second direction, the depth direction of the groove 141 is the third direction, and the width direction of the groove 141 is the first direction; the connecting portion 121 is arranged in the groove 141, so as to facilitate the installation of the connecting portion 121 and the first fixing seat 14; and the position between the connecting portion 121 and the first fixing seat 14 can be adjusted in the second direction, so that the position of the first hook 11 can be adjusted to facilitate the locking of the first hook 11 and the second hook 21.

[0058] The second locking assembly 2 can be fixed on other devices via the second fixing seat 22 .

[0059] In an optional embodiment, the first locking assembly 1 further includes a detection member 3, and the detection member 3 is used to detect whether the first hook 11 and the second hook 21 are locked with each other or separated.

[0060] In an optional embodiment, the detection member 3 includes a connecting plate 31 and a sensor 32, one end of the connecting plate 31 is connected to the mounting seat 12, the connecting plate 31 and the first hook 11 are spaced apart in the first direction, and the sensor 32 is arranged at the other end of the connecting plate 31.

[0061] like Figure 1 and Figure 2 As shown, the detection member 3 includes a connecting plate 31 and a sensor 32. One end of the connecting plate 31 is connected to the mounting base 12, and the connecting plate 31 and the first hook 11 are spaced apart along the first direction. The sensor 32 is arranged at the other end of the connecting plate 31 and is located on a side close to the first hook 11. When the first hook 11 and the second hook 21 need to be locked with each other, the first hook 11 rotates about the first direction toward the second hook 21. When the first hook 11 and the second hook 21 are locked with each other, the first hook 11 and the sensor 32 are at the same height, so the sensor 32 can detect the position of the first hook 11, thereby knowing that the first hook 11 and the second hook 21 are locked. If the first hook 11 rotates about the first direction toward the direction away from the second hook 21, the first hook 11 will also rotate out of the area that the sensor 32 can detect. In other words, the first hook 11 and the sensor 32 are at different heights, thereby knowing that the first hook 11 and the second hook 21 are separated.

[0062] The sensor 32 may be a photoelectric sensor or a distance measuring sensor.

[0063] In an alternative embodiment, Figure 2 As shown, the connecting plate 31 is provided with a long hole 311, the axial direction of the long hole 311 is the first direction, and the length direction of the long hole 311 is the second direction. The sensor 32 can be set at any position of the long hole 311 along the second direction, so that the position of the sensor 32 can be adjusted to facilitate the detection of the mutual locking or separation of the first hook 11 and the second hook 21.

[0064] In an optional embodiment, the first locking assembly 1 further includes a first connecting member 15 , which is provided on the first hook 11 , and the first connecting member 15 is used to connect a first traction rope.

[0065] like Figure 1-Figure 4 As shown, the first locking assembly 1 also includes a first connecting member 15; wherein, the first connecting member 15 is arranged on the first hook 11, specifically, the first connecting member 15 is arranged on the hook portion 112, and the first connecting member 15 is used to connect the first traction rope, and by pulling the first traction rope, the hook portion 112 is rotated around the first direction. Therefore, when the locking mechanism 100 is set at a high place, the maintenance personnel can pull the first traction rope to rotate the first hook 11 around the first direction, so that the first hook 11 and the second hook 21 are locked with each other or separated.

[0066] like Figure 1 As shown, in an optional embodiment, the second locking assembly 2 also includes a second fixing seat 22, and the second hook 21 is arranged on the second fixing seat 22; wherein the second hook 21 is fixedly connected to the second fixing seat 22, and the second fixing seat 22 provides an installation support for the second hook 21, and the second locking assembly 2 can be fixed to other devices through the second fixing seat 22.

[0067] like Figure 5-10 As shown, according to the second aspect of an embodiment of the present application, a maintenance platform device is provided, including a frame 4, a mobile platform 5 and a first locking mechanism 100A; the mobile platform 5 is arranged on the frame 4 and can move along the second direction; the first locking mechanism 100A adopts the above-mentioned locking mechanism 100, the second locking component 2 of the first locking mechanism 100A is arranged on the mobile platform 5, and the first locking component 1 of the first locking mechanism 100A is arranged on the device to be inspected 6.

[0068] like Figure 5As shown, the maintenance platform device includes a frame 4, a mobile platform 5 and a first locking mechanism 100A; wherein the mobile platform 5 is slidably connected to the frame 4, the mobile platform 5 can move along the second direction, and the mobile platform 5 is used to carry maintenance personnel to repair the device 6 to be repaired.

[0069] Further explanation, such as Figure 6 and Figure 9 As shown, the mobile platform 5 can move in the second direction to approach the device to be repaired 6. The second locking assembly 2 of the first locking mechanism 100A is arranged on the side of the mobile platform 5 close to the device to be repaired 6. When the device to be repaired 6 needs to be repaired, the mobile platform 5 is moved to the device to be repaired 6. The second locking assembly 2 is locked with the first locking assembly 1, thereby preventing the mobile platform 5 from moving in the second direction. Therefore, when the repair personnel repair the device to be repaired 6 on the mobile platform 5, the safety of the repair personnel is guaranteed. When the repair is completed, the first locking assembly 1 is separated from the second locking assembly 2, so that the mobile platform 5 can be moved to another location.

[0070] In an optional embodiment, the maintenance platform device also includes a second locking mechanism 100B, the second locking mechanism 100B adopts the above-mentioned locking mechanism 100, the second locking component 2 of the second locking mechanism 100B is arranged on the mobile platform 5, and the first locking component 1 of the second locking mechanism 100B is arranged on the frame 4.

[0071] like Figure 7 As shown, the maintenance platform device also includes a second locking mechanism 100B; the first locking component 1 of the second locking mechanism 100B is arranged on the frame 4, and the second locking component 2 of the second locking mechanism 100B is arranged on the side of the mobile platform 5 close to the frame 4 where the first locking component 1 is arranged. Therefore, when the maintenance platform device does not need to work, in order to prevent the mobile platform 5 from moving, the mobile platform 5 is moved to a preset position, and the second locking component 2 is locked with the first locking component 1, thereby preventing the mobile platform 5 from moving.

[0072] In an optional embodiment, the mobile platform 5 is provided with at least one second connecting member 51, and the second connecting member 51 is used to connect the second traction rope 52. In the third direction, the mobile platform 5 is higher than the ground, and the maintenance personnel on the ground move the mobile platform 5 to the device to be maintained 6 through the second traction rope 52; and the first hook 11 is provided with a first connecting member 15, and the first connecting member 15 is connected to the second traction rope 52. Therefore, the maintenance personnel on the ground can move the mobile platform 5 to the device to be maintained 6 through the second traction rope 52, and lock the first locking assembly 1 with the second locking assembly 2 through the first traction rope. The maintenance personnel can do it overnight, and the operation is simple.
