A transverse sliding rod 15 is arranged below the movable arm 3, and two ends of the sliding rod 15 are fixedly connected with the movable arm 3 through supporting plates 4 respectively. The left end of the support frame 8 is fixedly provided with a sliding sleeve 16, and the sliding rod 15 is connected with the sliding sleeve 16 in a penetrating and sliding manner. The support frame 8 is connected with a third auxiliary roller 17 in the right direction of the sliding sleeve 16 in a rotating mode, the right lower end of the support frame 8 is connected with a driving roller 9 in a rotating mode, and the support frame 8 is connected with a fourth auxiliary roller 7 in the upper portion of the driving roller 9 in a rotating mode.

The first auxiliary roller 1, the fourth auxiliary roller 7, the driving roller 9 and the third auxiliary roller 17 are arranged in an inverted trapezoid, the second auxiliary roller 5 is located in the inverted trapezoid, the conveyor belt 2 sequentially bypasses the first auxiliary roller 1, the second auxiliary roller 5, the third auxiliary roller 17, the driving roller 9 and the fourth auxiliary roller 7, a first driving unit 6 for driving the movable arm 3 to transversely move is arranged on the supporting frame 8, the first driving unit 6 is an electric push rod, and a speed reducing motor 10 connected with the driving roller 9 through a coupling in a transmission mode is arranged on the supporting frame 8.

The conveyor belt 2 is composed of five sections, namely a first section connected between the first auxiliary roller 1 and the fourth auxiliary roller 7, a second section connected between the fourth auxiliary roller 7 and the driving roller 9, a third section connected between the third auxiliary roller 17 and the driving roller 9, a fourth section connected between the third auxiliary roller 17 and the second auxiliary roller 5 in sequence, and a fifth section connected between the second auxiliary roller 5 and the first auxiliary roller 1, and is wrapped on the first section for conveying. The first section, the fifth section, the fourth section and the third section are parallel to each other, and the first section, the fifth section and the fourth section are connected with each other in sequence to form an S shape.

When the movable arm 3 moves, the length of the first section change and the length of the fourth section change compensate each other, specifically: when the movable arm 3 moves leftwards, the first segment increases in length and the fourth segment decreases in length, the first segment increasing in length and the fourth segment decreasing in length being equal. Similarly, when the movable arm 3 moves rightward, the length of the first segment decreases, the length of the fourth segment increases, and the decreased length of the first segment and the increased length of the fourth segment are equal. Therefore, when the movable arm 3 moves, the length of the first section change and the length of the fourth section change compensate each other, and the lengths of the second section, the third section and the fifth section are unchanged, so that the conveyor belt 2 is always in a tight state on the first auxiliary roller 1, the second auxiliary roller 5, the fourth auxiliary roller 7, the driving roller 9 and the third auxiliary roller 17, thereby ensuring that the first section is straight and does not droop, and ensuring smooth conveying of packages.

During actual manufacturing, the movable arms 3 and the sliding rods 15 are two in front-back symmetrical arrangement, the supporting frames 8 and the sliding sleeves 16 are also two in front-back symmetrical arrangement, the two movable arms 3 are fixedly connected through the cross beam, and the two supporting frames 8 are connected through another cross beam.

The working process of the utility model is as follows:

the utility model is placed between the carriage of the train and the luggage trailer, with the moveable arm 3 facing the carriage and being raised above the floor of the carriage, and the end of the support frame 8 remote from the moveable arm 3 being either close to the luggage trailer or above the luggage trailer. The speed reducing motor 10 is started, the package in the carriage is placed at the end part above the conveyor belt 2, and the speed reducing motor 10 drives the conveyor belt 2 to rotate, so that the package is conveyed to the luggage trailer. When the package in the depth of the carriage needs to be unloaded, the first driving unit 6 acts to enable the movable arm 3 to extend outwards, so that the length of the first section of the conveyor belt 2 is prolonged, and the package in the depth of the carriage is conveniently unloaded. When a package is to be loaded onto the compartment from the luggage trailer, the gear motor 10 is simply turned over.

By using the utility model, the labor intensity of package handling can be reduced, thereby achieving the purposes of time and labor saving.
