[0027] The top of the electro-hydraulic push rod 4 is installed with a fixing bracket 3. Both ends inside the fixing bracket 3 are installed with first driving members. The output end of the first driving member is connected with a tipping adjustment seat 2. The pin hook removing member 1 is installed on the top of the tipping adjustment seat 2.

[0028] Second driving members are installed on both sides of the pin hook removing member 1. An infrared camera 17 is installed at the middle position on the top of the pin hook removing member 1. Both ends on the top of the pin hook removing member 1 are connected with clamping arms 15 through rotating shafts. A connecting rod 16 is connected between the output end of the second motor 14 and the clamping arm 15 through a rotating shaft.

[0029] During use, the infrared camera 17 will detect the anti-rolling device on the shunting locomotive. The working state of the anti-rolling device can be judged manually through the pictures collected by the infrared camera 17. Then, the first driving part is started to drive the flipping and adjusting seat 2 and the pin hook part 1 installed thereon to automatically flip, adjust the hooking position of the pin hook part 1, and enhance the applicability. Then, the second driving parts on both sides of the pin hook part 1 are started to drive the connecting rod 16 to rotate, and the left and right flipping of the clamping arms 15 connected to the connecting rod 16 is realized. This can realize the clamping and fixing of the locking pin of the anti-rolling device on the shunting locomotive by the two clamping arms 15. Subsequently, the electro-hydraulic push rod 4 is started to automatically detach and strip the locking pin of the anti-rolling device on the shunting locomotive.
