[0028] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0029] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a variety of structural modes and implementation modes can be replaced by those skilled in the art. Therefore, the following specific implementation methods and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction on the technical solution of the utility model.

[0030] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0031] like Figure 1 to Figure 2As shown, the present application provides a patrol robot coupling device, comprising a patrol robot 1 and a track connector 2. The patrol robot 1 and the track connector 2 are connected via a connecting mechanism 3. The track connector 2 can be a track patrol vehicle or other detection mechanism used on the track.

[0032] The connection mechanism 3 includes two connection hooks 30 , and the two connection hooks 30 are connected to the inspection robot 1 and the track connection member 2 respectively.

[0033] like Figures 3 to 5 As shown, the connecting mechanism 3 also includes two detachably engaged hooks 31, and the two hooks 31 are rotatably arranged on the two connecting hooks 30 respectively. After the two hooks 31 are rotatably engaged, a locking member 32 is correspondingly abutted on the limiting area of ​​each hook 31 to engage and lock the two hooks 31.

[0034] like Figures 5 and 6 As shown, the hook member 31 in the embodiment of the present application is a U-shaped structure. Of the two side walls of the U-shaped structure, a clamping protrusion 311 is provided at the end of one side wall and is engaged with the clamping protrusion 311 on the side wall of the other U-shaped structure through the clamping protrusion 311; the other side wall is rotatably mounted on the connecting hook 30 and is provided with a limiting area engaged with the locking member 32. The thickness of the side wall of the U-shaped structure is slightly smaller than the width of the middle space of the U-shaped structure, so that a small gap is left between the two hook members 31 after being engaged.

[0035] In the embodiment of the present application, when the inspection robot 1 and the track connector 2 are connected through the connection mechanism 3, force is applied to rotate the two hooks 31 and when they are rotated to a preset position, each hook 31 is locked by the locking member 32, and the hook 31 cannot rotate, so that the two hooks 31 are in a stable engaged state. The engaged hooks 31 are stable and ensure good traction. The engaging structure has a certain buffering capacity at the connection point, which increases the buffering effect compared to the hard connection, reduces the inertial impact caused by braking, and improves the inspection quality and accuracy. When separation is required, the locking member 32 is driven to separate from the limit area, and the hook 31 is rotated in the opposite direction to separate.

[0036] As an optional embodiment, the inspection robot 1 is fixedly connected to a fixed support plate 10, the track connector 2 is fixedly connected to a connecting plate 20, and the two connecting hooks 30 are respectively connected to the fixed support plate 10 and the connecting plate 20. Figure 1 to Figure 2 As shown, the fixed support plate 10 in the embodiment of the present application is L-shaped, and the vertically arranged part is fitted with the corresponding installation part of the inspection robot 1 and fixedly connected by bolts. The connecting plate 20 is arranged horizontally, and the track connector 2 is fitted with the connecting plate 20 and fixedly connected by bolts.

[0037] As an optional embodiment, a connection slot 300 is provided in the connection hook 30, the locking member 32 is movably mounted on the connection hook 30, a limiting plate 320 is provided on the locking member 32 and is located in the connection slot 300, and the limiting area of ​​the hook member 31 includes a limiting step 310 that is sunken and arranged downward, and after the two hook members 31 rotate to engage with each other, the limiting step 310 rotates into the connection slot 300 and abuts against the limiting plate 320 to limit the position. Figure 5 As shown, an L-shaped step is provided on the hook 31. When the two hooks 31 are engaged, the limiting plate 320 abuts against the vertical part of the L-shaped step to limit the rotation of the hook 31, thereby ensuring the stability of the two hooks 31 after engagement.

[0038] As an optional embodiment, any of the connecting mechanisms 3 further includes two compression springs 33. The compression springs 33 are compressed and arranged between the locking member 32 and the connecting hook 30, and the compression direction of the compression springs 33 is the same as the movable direction of the locking member 32. The compressed compression springs 33 generate a downward restoring force on the locking member 32. When the hook member 31 moves to the lowered L-shaped limiting step 310 and is located below the locking member 32, the locking member 32 moves downward under the action of the compression springs 33 until the limiting plate 320 abuts against the lateral part of the L-shaped limiting step 310. When the two hook members 31 move to engage with each other, the limiting plate 320 abuts against the vertical position of the L-shaped limiting step 310 so that the hook member 31 cannot continue to rotate.

[0039] As an optional embodiment, the locking member 32 further includes a mounting seat 321 and a connecting portion 322, the limiting plate 320 is connected to the mounting seat 321 through the connecting portion 322 and is arranged opposite to each other; a limiting hole 323 is provided on the mounting seat 321, and a portion of the compression spring 33 is arranged in the limiting hole 323, and the compression direction of the compression spring 33 is the same as the axial direction of the limiting hole 323. Figures 5 and 6 As shown, the connecting portion 322 in the embodiment of the present application can be a rod or plate-like structure, which plays the role of connecting the mounting seat 321 and the limiting plate 320. The limiting hole 323 limits the compression spring 33 and guides the compression spring 33 to expand and contract along the axial direction of the limiting hole 323.

[0040] As an optional embodiment, the locking member 32 further includes a locking tongue 324, which is slidably arranged along the compression direction of the compression spring 33 and partially extends out of the connecting hook 30, and the portion of the locking tongue 324 located outside the connecting hook 30 is connected to a pull ring 325. Figures 2 to 3As shown, the locking tongue 324 in the embodiment of the present application is a rod-shaped structure. If the inspection robot 1 and the track connector 2 need to be separated from each other, the operator lifts the two pull rings 325 upward to move the locking tongue 324 upward, and then applies force to separate the inspection robot 1 from the track connector 2.

[0041] As an optional embodiment, any of the connecting hooks 30 is fixedly connected to a protective portion, the protective portion is fixed to the connecting hook 30, and the hook member 31 is at least partially located in the protective portion and rotatably connected to the protective portion. The protective portion protects and rotatably positions the hook member 31.

[0042] As an optional embodiment, the protection part includes two oppositely disposed protection plates 301, and the hook 31 is located between the two protection plates 301 corresponding to the protection part and is rotatably connected to the two protection plates 301 through the pin 4. Figure 3 and Figure 6 As shown, the pin shaft 4 in the embodiment of the present application passes through the hook 31 and the guard plates 301 located on both sides of the hook 31, serving as the rotation axis of the hook 31 and playing a role in rotational positioning of the hook 31. The two guard plates 301 define a space for accommodating and protecting the hook 31.

[0043] As an optional embodiment, the pin shaft 4 includes a positioning end, the positioning end extends to the outside of the guard plate 301, and the positioning end is detachably mounted with a positioning pin 40, and the axial direction of the positioning pin 40 is at a right angle or an acute angle to the axial direction of the pin shaft 4. Figure 4 and Figure 5 As shown, a positioning hole is provided at the positioning end, and a positioning pin 40 is detachably installed in the positioning hole. After the positioning pin 40 is removed, the pin shaft 4 can be removed from the guard plate 301 and the hook 31, so that the guard plate 301 is separated from the hook 31. After the positioning pin 40 is installed on the pin shaft 4, the pin shaft 4 stably connects the guard plate 301 and the hook 31.

[0044] As an optional embodiment, a slot 326 is provided at the bottom of any of the mounting seats 321, and the guard plate 301 is snapped into the slot 326. The slot 326 is movably arranged along the guard plate 301 along the compression direction of the compression spring 33. A snap-in wall of the slot 326 is located on the outer side of the guard plate 301, and the mounting seat 321 is limited by the guard plate 301.
