[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example

[0019] See also Figure 1-3The present invention provides the following technical solutions: a device for detecting wear of a rail transit power supply contact network line, comprising a measuring instrument 1, which is a FTJC-2A type contact network wear measuring instrument 1. The measuring instrument 1 is mounted on the upper surface of a connecting block 2, a rotating shaft 3 is embedded in the connecting block 2, and the rotating shaft 3 is disposed in a bearing 4, which is embedded in the side of a fixed block 5;

[0020] By means of the above structure or mechanism: the arrangement of the bearing 4 and the rotating shaft 3 can make the connecting block 2 rotate, and the angle of the measuring instrument 1 can be adjusted, so as to facilitate detection at different positions of the contact line through the measuring instrument 1.

[0021] A fixed shell 6 is fixedly provided on the lower surface of the fixed block 5, and a drive motor 7 is installed in the fixed shell 6. The surfaces of the rotating shaft 3 and the output shaft of the drive motor 7 are fixedly connected with a first gear 8 and a second gear 9 respectively, and the first gear 8 is meshed with the second gear 9.

[0022] By means of the above structure or mechanism, the working state of the driving motor 7 can be controlled to rotate the measuring instrument 1 so that the measuring instrument 1 can contact different positions of the contact network, thereby improving the detection effect of the contact network.

[0023] Specifically, a telescopic rod 10 is fixedly provided on the lower surface of the fixed shell 6, and a side surface of the telescopic rod 10 is fixedly connected to a limiting plate 11. Two limiting grooves 12 are provided on the surface of the limiting plate 11, and a slider 13 is slidably connected in the limiting groove 12. A pin shaft 14 is provided between the two sliders 13, and a support rod 15 is hinged on the surface of the pin shaft 14.

[0024] By means of the above structure or mechanism: the position of the measuring instrument 1 can be adjusted by the telescopic rod 10, so that the contact network can be detected by the measuring instrument 1; the slider 13 slides in the limit groove 12, and the setting of the pin shaft 14 facilitates the rotation of the support rod 15, thereby facilitating the adjustment of the position of the support rod 15.

[0025] Specifically, a clamping rod 16 is fixedly connected to the side of the support rod 15, and the clamping rod 16 is clamped in a through hole 17 opened on the side of the limiting plate 11. The bottom ends of the telescopic rod 10 and the support rod 15 are respectively provided with handles 18.

[0026] By means of the above-mentioned structure or mechanism: the setting of the two handles 18 allows the staff to hold the handles 18 with both hands at the same time to lift the measuring instrument 1. Compared with the method of holding a single rod with both hands, the two handles 18 are more stable; in the process of keeping the measuring instrument 1 stable, the two handles 18 have different upper and lower positions, and the staggered position supports the telescopic rod 10, thereby improving the stability of the measuring instrument 1.

[0027] The working principle of this utility model is:

[0028] During use, the usage of the measuring instrument 1 itself remains unchanged. The following can be adjusted during the measurement process:

[0029] The operating state of the drive motor 7 is controlled by a control system (not shown in the figure; a control panel may be provided at the position where the bottom end of the telescopic rod 10 is connected to the handle 18). The output shaft of the drive motor 7 engages the first gear 8 via the second gear 9, causing the rotating shaft 3 to rotate the connecting block 2, thereby driving the measuring instrument 1 to rotate. At this time, the contact position between the measuring part of the measuring instrument 1 and the contact network can be changed.

[0030] At the same time, during use, the staff can separate the clamping rod 16 from the through hole 17 by rotating the support rod 15, and rotate the support rod 15 at a suitable position to clamp the clamping rod 16 with the relative through hole 17, which makes it convenient for the staff to support the measuring instrument 1 with both hands.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated on.

[0032] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0033] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
