In order to further improve the maintenance efficiency and safety, a grinding trolley can be used to replace the manual identification and grinding operations. For example, the utility model patent with the announcement number CN 208601227 U discloses a contact line grinding machine for a rigid contact network, including a frame and a walking mechanism and a grinding mechanism respectively installed on the frame. The grinding mechanism includes a grinding motor and a grinding wheel driven by the grinding motor to realize automatic advancement and grinding of the grinder. However, during the running and grinding process of the grinder, the vibration of the grinder will be transmitted to the rigid contact network, causing the connection nodes of various equipment of the rigid contact network to loosen, and even cause falling off and damage. In addition, the grinder is not designed with detection equipment, does not have the contact line detection function, cannot collect on-site images, and cannot realize remote identification and control based on real-time images.

[0034] The utility model provides a subway rigid contact network inspection and grinding trolley, which is installed on the bus 1 of the rigid contact network and can travel on the bus 1 to a specified position to grind the contact line 12. Figure 2 As shown, the contact wire 12 is clamped between the bottom ends of the clamp feet on both sides of the busbar 1. The outer side of the clamp feet has an outer protrusion, and the bottom of the outer protrusion has a longitudinal positioning groove 13.

[0035] like Figure 1-5 The body 9 of the grinding trolley is provided with a frame 3, a driving wheel 2 and a positioning guide wheel 4. The frame 3 is located on both sides of the top of the body 9 and is arranged vertically. A running drive motor 5 is arranged on the inner side of the frame 3. The driving wheel 2 is installed on the output shaft of the running drive motor 5. The positioning guide wheels 4 are arranged in pairs on the inner side of the frames 3 on both sides and are located below the driving wheel 2. Figure 5In the embodiment, there are four frames 3 arranged front, back, left and right, and a set of driving wheels 2 and positioning guide wheels 4 are arranged on the inner side of each frame, arranged up and down. The frame 3, the driving wheel 2 and its running drive motor 5, and the positioning guide wheel 4 constitute the running mechanism of the grinding trolley. The running surface of the driving wheel 2 is the top surface of the outer protrusion at the bottom of the bus 1, and the running surface of the positioning guide wheel 4 is the positioning groove 13 set on the bottom surface of the outer protrusion at the bottom of the bus 1. During the running process, because the positioning guide wheel 4 is embedded in the positioning groove 13, and clamps the outer protrusion of the bus up and down together with the driving wheel 2 above, the grinding trolley is not prone to lateral deviation, and the running is more stable.

[0036] A grinding wheel 6 is also provided on the top of the vehicle body 9, and the grinding wheel 6 is located in the top center of the vehicle body 9. A motor base 15 is provided on the top of the vehicle body 9, and a grinding drive motor 16 is provided on the top of the motor base 15, and the grinding wheel 6 is installed on the output shaft of the grinding drive motor 16. The grinding wheel 6 and its grinding drive motor 16 and the motor base 15 constitute the grinding mechanism of the grinding trolley, and the grinding wheel 6 corresponds to the contact line 12 upward. When the grinding trolley moves to the specified position, the grinding drive motor 16 starts, and the grinding wheel 6 grinds the contact line 12, and is turned off after the grinding is restored to its original shape. Figure 4 In the embodiment, the motor base 15 can adopt an existing lifting base, and the position of the grinding drive motor 16 can be adjusted according to the height of the contact line 12, thereby ensuring that the grinding wheel 6 is in close contact with the contact line 12, and then lowered to its original position after grinding.

[0037] like Figure 5 The lower part of the frame 3 is a hollow structure with an open bottom. A shock absorber 7 is arranged in the hollow structure. The top of the shock absorber 7 is connected to the top of the hollow structure, and the bottom of the shock absorber 7 is exposed in the hollow structure and connected to the top of the vehicle body 9. In some embodiments, the shock absorber 7 may include a vertical spring and a vibration-damping pad. The shock absorber 7 forms a seismic isolation connection between the frame 3 and the vehicle body 9. When the grinding mechanism is running, its vibration will be weakened by the shock absorber 7, so the vibration transmitted to the frame 3 is small, and the impact on the bus 1 will also be greatly reduced.

[0038] A dust box 8 is also provided on the top of the vehicle body 9, and the dust box 8 is located below the grinding wheel 6. A funnel-shaped dust collection port 14 is provided on the top of the dust box 8. The debris generated during the grinding of the contact line 12 by the grinding wheel 6 can enter the dust collection port 14 and be collected by the dust box 8 without falling onto the vehicle body 9, thereby avoiding affecting other components of the vehicle body 9 and solving the pollution problem existing in the previous grinding.

[0039] In addition, a camera 11 is provided on the front side of the vehicle body 9, and the viewing angle is directed upward to the contact line 12. In some embodiments, the camera 11 is mounted on the front side of the vehicle body 9 via a rotatable camera support. During the movement of the grinding trolley, the operator can identify the state of the rigid contact network through the image information collected by the camera 11, and judge whether the contact line 12 needs to be polished. When the position that needs to be polished is determined, the movement of the grinding trolley is stopped, and the grinding wheel 6 is started to start grinding.

[0040] The bottom of the body 9 of the polishing trolley can be provided with an antenna 10, which is used for the operator to remotely control various drive motors of the polishing trolley, and can also be used for picture information transmission. A storage battery can also be configured in the body 9 of the polishing trolley to provide power for the corresponding components of the polishing trolley.

[0041] The grinding trolley designed by the utility model integrates multiple functions such as grinding, image acquisition, dust collection, and vibration reduction. It has high efficiency, low labor intensity, can be remotely controlled, can obtain real-time images for identification and detection, and effectively control pollution. At the same time, it solves the impact of equipment vibration on the contact network. The running mechanism is connected to the vehicle body 9 through the shock absorber 7. During the running detection of the grinding trolley, the shock absorber 7 can effectively block the vibration from the running drive motor 5, the driving wheel 2, and the positioning guide wheel 4, so that the grinding trolley can move forward steadily and at a uniform speed to ensure the quality of the detection. In the process of the grinding trolley stationary grinding the contact line 12, the shock absorber 7 attenuates and blocks the vibration of the grinding mechanism from being transmitted to the rigid contact network. In addition, the impact on the operation of the camera 11 is also reduced, ensuring the acquisition accuracy.

[0042] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
