[0023] In this embodiment, the contact mechanism 7 includes a power supply base 3, a vertical guide rod 9 and a hydraulic cylinder 10. The hydraulic cylinder 10 is arranged inside the charging foundation 1. The output end of the hydraulic cylinder 10 is connected to the bottom end of the power supply base 3. The two sides of the power supply base 3 are penetrated by the vertical guide rod 9, and the two sides of the power supply base 3 are positioned and guided by the vertical guide rod 9.

[0024] In this embodiment, the power supply base 3 is connected to the wire pipe 1 4 and the wire pipe 2 5 arranged at equal intervals at the top, and the power supply base 3 is used to power the robot, and the power supply is performed on multiple groups of robots.

[0025] In this embodiment, the elastic mechanism 16 includes a wire tube 1 4, a wire tube 2 5, a wireless charging module 6, a guide slider 12, a guide slot 13, a threading hole 14 and a reset spring 15. The guide slot 13 is provided in an annular shape inside the wire tube 1 4. A reset spring 15 is provided inside the guide slot 13. The top of the reset spring 15 is connected to the guide slider 12. The guide slider 12 is distributed in an annular shape on the wire tube 2 5. The top of the wire tube 2 5 is provided with a wireless charging module 6. The wire tube 2 5 is provided with a threading hole 14 in an annular shape inside. The wire tube 2 5 is positioned by the guide slider 12 to prevent corrosion of the cable by external rainwater.

[0026] In this embodiment, the wire tube 2 5 is connected to the input end of the wireless charging module 6 through the power supply line 11 running through the inside, and the bottom of the robot is contacted and powered by the charging module 6 .

[0027] In this embodiment, the wire tube 2 5 is connected to the power supply line 11 through a wire threading hole 14 formed inside, and the equipment is powered by the wire tube 2 5, which facilitates power supply to robots of different heights.

[0028] The practical application of this rail inspection robot wireless charging device includes the following work contents:

[0029] Step 1: The operator fits the tires of the inspection robot to the rails 2 so that the inspection robot moves outside the charging base 1. When multiple groups of inspection robots move to the top of the corresponding wireless charging modules 6, the operator first turns on the hydraulic cylinder 10 to drive the power supply base 3 to rise vertically. The power supply base 3 is vertically guided by the vertical guide rods 9 arranged on both sides.

[0030] Step 2: The operator takes out the power supply line 11 provided inside the power supply base 3, inserts the power supply line 11 into the inside of the wire tube 1 4, and then inserts the power supply line 11 into the wire threading hole 14 provided inside the wire tube 2 5, so that the output end of the power supply line 11 is connected to the access end of the charging module 6, thereby completing the power connection process of the device;

[0031] Step 3: When the charging module 6 and the lithium battery of the inspection robot are in contact with each other, when the charging module 6 moves upward, the charging module 6 transmits the pressure to the inside of the wire tube 2 5, and the wire tube 2 5 slides vertically in the guide groove 13 opened at the inner end of the wire tube 1 4 through the guide slider 12 arranged on the outside, and the reset spring 15 supports the bottom end of the guide slider 12 to prevent the charging module 6 from being unable to be effectively reset after sliding during the downward movement;

[0032] Step 4: When the charging module 6 is working, the input end converts the AC mains into DC power through a full-bridge rectifier circuit, or uses a 24V DC power end to directly power the system, thereby completing the power supply processing of the lithium battery inside the robot. At the same time, when rainwater from the outside flows into the interior of the charging foundation 1, the charging foundation 1 discharges the rainwater through the water filter plate 8 arranged at the bottom to prevent rainwater from accumulating inside the charging foundation 1.

[0033] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
