Each connection box 19 is connected with a consignment plate 20 through a spring. By setting the connection through a spring, it is prevented from hindering the movement of the clamping plate 2. The consignment plate 20 is set to be L-shaped. Two support plates 21 are respectively connected to the two consignment plates 20 through springs, so as to avoid impacting the support plate 21 when the sleeper falls on the support plate 21.

[0062] As Figures 2 to 6 shown in

[0063] The working principle of the sleeper lifting device is as follows: When it is difficult to clamp the sleeper directly placed on a horizontal plane, the sliding cart 1 is driven to move above the sleeper, and then the first motor 4 is started. The first motor 4 drives the first lead screw 5 to rotate, thereby driving the connecting frame 7 to slide downward along the vertical direction on the first guide bar 6. The connecting frame 7 then drives the transmission mechanism 002, the clamping mechanism 003, the clamping plate 2, the friction plate 3 and the consignment mechanism 004 to move vertically downward.

[0064] When the bottom of the clamping plate 2 touches the horizontal plane, the first motor 4 is shut down. At the same time, since the connecting box 19 and the consignment plate 20 are connected by a spring, the consignment plate 20 is pushed into the connecting box 19 by the horizontal plane, and the bottom of the consignment plate 20 touches the horizontal plane.

[0065] Then the second motor 9 is started, driving the first bevel gear 10 to rotate, thereby driving the second bevel gear 12 to rotate, then driving the transmission shaft 11 to rotate, and then driving the two third bevel gears 13 fixedly connected to both ends of the transmission shaft 11 to rotate. The two third bevel gears 13 respectively drive the two fourth bevel gears 14 to rotate, thereby driving the two clamping gears 15 to rotate. Each clamping gear 15 then drives the clamping racks 16 located on both sides of the clamping gear 15 to slide in the first sliding groove, thereby driving the clamping plates 2 fixed to the bottoms of the two clamping racks 16 to move in the relatively close direction, thereby clamping the sleeper.

[0066] Then the second motor 9 is shut down, and the first motor 4 is started to reverse. The first motor 4 drives the first lead screw 5 to reverse, thereby driving the connecting frame 7 to slide upward along the vertical direction on the first guide bar 6. The connecting frame 7 then drives the transmission mechanism 002, the clamping mechanism 003, the clamping plate 2, the friction plate 3 and the consignment mechanism 004 to move vertically upward.

[0067] After moving a certain distance, the third motor 22 is started, driving the fifth bevel gear 23 to rotate, thereby driving the sixth bevel gear 25 to rotate, then driving the second lead screw 24 to rotate, and then driving the two connecting boxes 19 to slide in the relatively close direction on the second guide bar 26.

[0068] When the two connecting boxes 19 slide a certain distance, turn off the third motor 22, and then start the second motor 9 to reverse the second motor 9, driving the first bevel gear 10 to reverse, thereby driving the second bevel gear 12 to reverse, thereby driving the second bevel gear 12 to reverse, thereby driving the transmission shaft 11 to reverse, thereby driving the two third bevel gears 13 fixedly connected to both ends of the transmission shaft 11 to reverse. The two third bevel gears 13 respectively drive the two fourth bevel gears 14 to reverse, thereby driving the two clamping gears 15 to reverse. Each clamping gear 15 then drives the clamping racks 16 located on both sides of the clamping gear 15 to slide in the first sliding groove, thereby driving the clamping plates 2 respectively fixed to the bottoms of the two clamping racks 16 to move in the relatively far away direction, thereby loosening the sleeper and allowing the tie to fall onto the support plate 21.

[0069] Then drive the sliding vehicle 1 to move the sleeper to the designated position.

[0070] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
