The roller 10 in the roller basket 11 is lifted together with the roller basket 11 after the rear roller recovery vehicle recovers and loads the basket by a lifting device arranged on the rear roller recovery vehicle.

Preferably, four drum baskets 11 are actually placed, one behind the other on both left and right sides of the drum storage tank 1.

As shown in fig. 1, 11, 12; the tractor also comprises two automatic locking manipulators 8 which are used for grabbing and locking the steel rail 9 and are respectively arranged on the left side and the right side of a cross beam 19 which can be lifted and sunk at the rear part of the tractor; the automatic locking manipulator 8 comprises a fixed seat 81, a clamping assembly and an inclined pushing cylinder 83; the fixing seat 81 is fixed on the cross beam 19, and the clamping assembly comprises a main frame 82 and a gripping device arranged at the lower end of the main frame 82; the main frame 82 is arranged on the fixed seat 81 through a first rotating shaft 84; the inclined propelling cylinder 83 is mounted on the fixing seat 81, and the propelling end of the inclined propelling cylinder is connected with the main frame 82 through the second rotating shaft 85 above the first rotating shaft 84 and can propel the main frame 82 to rotate around the first rotating shaft 84. When the grasping device grasps the rail 9, the grasped rail 9 is lifted up by lifting the beam 19, and then the main frame 82 is rotated by the tilt cylinder 83 to tilt the main frame 82 in the longitudinal direction of the rail 9, whereby the grasped rail 9 can be further locked, the main frame 82 can be returned, and the locked rail 9 can be released.

The reason why the main frame 82 is pushed to incline to enable the grasping device to lock the steel rail 9 is that the grasping device only hangs the rail head 91 of the steel rail 9 when grasping the steel rail 9 and can only lift the steel rail 9, but does not completely grasp the steel rail 9, and the stress requirement of pushing and pulling the steel rail 9 cannot be met. The principle that the main frame 82 is pushed to incline to enable the grasping device to lock the steel rail 9 is that partial gravity of the steel rail 9 is converted into fastening force of the grasping device to the steel rail 9 by changing stress angles of stress components in the grasping device and the steel rail 9 so as to meet stress requirements of pushing the steel rail 9, and the principle is further explained by combining a disclosed structure later.

The inclined propelling cylinder 83 can be a pneumatic cylinder or an electromagnetic cylinder, and preferably, an oil cylinder is selected and used in the utility model.

As shown in fig. 11 to 15, the main frame 82 includes a connecting plate 821, and a first mounting plate 822 and a second mounting plate 823 symmetrically fixed on two sides of the connecting plate 821, and a space is formed between the first mounting plate 822 and the second mounting plate 823 to form a mounting space 824; the gripping device comprises a first hanging pin 88 and a second hanging pin 89, the first hanging pin 88 and the second hanging pin 89 are respectively positioned in a first hanging pin hole 8223 and a second hanging pin hole 8233 which are symmetrically arranged at the lower ends of a first mounting plate 822 and a second mounting plate 823, and the first hanging pin 88 and the second hanging pin 89 can be respectively inserted into and pulled out of the first hanging pin hole 8223 and the second hanging pin hole 8233. In a preferred embodiment of the present invention, when the grasping device grasps the rail 9, the rail 9 head 91 is grasped by extending the first and second hooks 88 and 89 from the two sides of the rail 9 to the lower bottom surfaces of the two sides of the rail 9 head 91, and the rail 9 can be first lifted up and then further set for grasping the rail 9.

The inclination of the lower end of the main frame 82 is performed by the thrust force applied from the inclination cylinder 83 to the lower portion of the main frame 82. When the thrust applied by the inclined propelling cylinder 83 is maintained, the automatic bidirectional locking mechanism of the steel rail 9 of the whole automatic locking manipulator 8 temporarily forms a rigid whole, namely a specific fixed posture can be temporarily kept, so that the traction force of the track laying vehicle is instantly transmitted to the locked steel rail 9, and the steel rail 9 can be pushed and pulled.
