The first hook 2 and the second hook 3 are rotatably connected between the two mounting plates 11. This allows the first hook 2 and the second hook 3 to rotate relative to each other inside the mounting frame 1 to clamp the rail sleeper. It should be noted that the structure of the mounting frame 1 does not necessarily have to be divided into the above-mentioned mounting plates 11 and the top frame 12. It can also be an integrated structure, as long as it can be connected to external equipment and has a spare area inside to rotatably connect the first hook 2 and the second hook 3 to the mounting frame 1.

[0038] The first drive cylinder 4 is arranged between the two mounting plates 11. The cylinder body and the end of the telescopic rod of the first drive cylinder 4 are both rotatably connected to the first hook 2 and the second hook 3. When the first drive cylinder 4 is working, the telescopic rod of the first drive cylinder 4 moves back and forth, which can push the first hook 2 and the second hook 3 to move closer to or away from each other, thereby completing the picking up or placing of the sleeper. When in use, the mounting frame 1 can be fixed on the construction equipment, and the construction equipment places the sleeper clamping device of the present application at the sleeper position. The first drive cylinder 4 compresses and drives the first hook 2 and the second hook 3 to rotate in a direction close to each other, thereby clamping the sleeper, and then being driven to move by the construction equipment, thereby replacing the previous manual picking up of the sleeper, reducing the consumption of labor costs, improving the safety of construction, and improving construction efficiency.
