[0027] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0028] The contact surface between the roller structure of the existing inspection device and the transmission line is usually a plane, so that the roller cannot fit in the process of rolling contact with the transmission line track, so it is easy to shake. In order to solve the above technical problems, the utility model provides a track inspection mechanism and a monitoring device, which can stably move on the transmission line and perform inspection tasks. Specifically:

[0029] A track inspection mechanism comprises a shell assembly, a limiter and two groups of rolling assemblies; the two groups of rolling assemblies are respectively arranged on both sides of the shell assembly along the moving direction; the rolling assembly comprises rollers and waisted rollers arranged opposite to each other in the vertical direction, and the waisted rollers are arranged above the rollers; the limiter is arranged between the two groups of rolling assemblies and on the side of the rolling assembly away from the shell assembly; the cross-section of the limiter, roller and waisted roller along the rolling direction forms an annular receiving portion for covering a transmission line.

[0030] From the above description, it can be seen that the beneficial effect of the utility model is that: a rolling assembly is composed of a roller and a waisted roller, and the arc-shaped rolling surface of the waisted roller can increase the contact area between the waisted roller and the transmission line, and fit with the transmission line. At the same time, a limiter is provided on the side of the rolling assembly away from the shell assembly, and the limiter, the roller and the waisted roller form an annular receiving portion in the cross-section along the rolling direction, so that the rolling structure of the track inspection mechanism is more adapted to the circular shape of the transmission line, thereby reducing shaking during movement, improving the stability of the operation of the track inspection mechanism, and enabling the monitoring device to stably move on the transmission line to perform inspection tasks.

[0031] Further, a limiting annular piece is arranged on one side of the waist - shrinking roller close to the housing assembly.

[0032] As can be seen from the above description, by arranging a limiting annular piece on one side of the waist - shrinking roller close to the housing assembly, and clamping both sides of the power transmission line through the limiting annular piece and the limiting piece, the stability is improved.

[0033] Further, each of the rolling assemblies includes a steering mechanism, a driving motor, and a main shaft; the steering mechanism, the driving motor, and the main shaft are all arranged inside the housing assembly; the driving motor and the main shaft are connected to the steering mechanism; the driving motor is in transmission connection with the main shaft; both ends of the main shaft penetrate through the housing assembly and are respectively connected to one of the waist - shrinking rollers.

[0034] As can be seen from the above description, by arranging a steering mechanism, a driving motor, and a main shaft, the movement and steering control of the track inspection mechanism can be realized, which is more conducive to the movement of the track inspection mechanism on the power transmission line.

[0035] Further, fixing columns and elastic members are arranged on the inner walls of two opposite sides of the housing assembly; the fixing columns are arranged between two sets of the steering mechanisms; one end of the elastic member is connected to the fixing column, and the other end of the elastic member is connected to one set of the steering mechanisms.

[0036] As can be seen from the above description, by arranging fixing columns between two sets of steering mechanisms and connecting the two sets of steering mechanisms to the fixing columns through elastic members respectively, the stability of the track inspection mechanism during the steering process is improved.

[0037] Further, rolling patterns are arranged on the rolling surface of the waist - shrinking roller.

[0038] As can be seen from the above description, by arranging rolling patterns on the rolling surface of the waist - shrinking roller, the friction between the waist - shrinking roller and the power transmission line is increased, and the stability of the track inspection mechanism moving on the power transmission line is improved.

[0039] Further, the rolling assembly further includes a support rod; one end of the support rod is connected to the housing assembly, and the other end is connected to the roller.

[0040] As can be seen from the above description, the support rod is arranged to play a role in fixing the roller.

[0041] Further, it further includes a gantry and a support member; the support member is arranged on the housing assembly; the gantry is connected to the support member and is erected on one side of the housing assembly away from the roller; the limiting members are arranged on both sides of the gantry and face the housing assembly.

[0042] As can be seen from the above description, by providing the gantry and the support member, it is more conducive to the arrangement of the limit piece and reduce the interference between structures.

[0043] Furthermore, the housing assembly is provided with a fixing structure; the fixing structure is used for connecting with an external device.

[0044] As can be seen from the above description, by providing a fixing structure on the housing assembly, it is more convenient for the external device to be connected to the housing assembly, thereby realizing corresponding functions.

[0045] Furthermore, the housing assembly includes an upper shell and a lower shell that are detachably connected.

[0046] As can be seen from the above description, by forming the housing assembly from an upper shell and a lower shell that are detachably connected, it is more conducive to the installation and maintenance of internal structures such as the roller assembly.

[0047] Another embodiment of the present invention provides a track inspection and monitoring device, including a camera module and the above-mentioned track inspection mechanism; the camera module is provided with a mounting structure; the mounting structure is cooperatively mounted with the fixing structure of the track inspection mechanism.

[0048] As can be seen from the above description, by providing a mounting structure on the camera module and cooperatively mounting the mounting structure of the camera module with the fixing structure of the track inspection mechanism, the overall device realizes the function of inspecting on the power transmission line.
