The transfer car body 1 comprises a cargo bed 11 and a plurality of transfer wheels 12 arranged at the bottom of the cargo bed 11. The transfer vehicle may be a manual transfer vehicle or an automatic transfer vehicle managed by a corresponding processor or processing system.

The base 21 is fixed at the bottom of the cargo carrying flat plate 11 of the transfer vehicle body 1, the rotating shaft 24 is arranged at one end of the base 21, one end of the electromagnet 23 is connected with the base 21 through the telescopic rod 22, the other end of the electromagnet 23 is connected with the baffle 25 through the rotating shaft 24, and the baffle 25 is a metal baffle or metal is embedded on the baffle 25.

Specific: the baffle 25 is a metal baffle made of at least one metal of iron, cobalt and nickel, or at least one metal of iron, cobalt and nickel is embedded in the baffle 25.

In practical implementation, the rotating shaft 24 may be a large rotating shaft, and includes a fixed shaft center (the shaft center is fixedly connected with the base 21) and two rings sleeved on the shaft center and capable of rotating around the shaft center, the two rings are distributed in a dislocation manner on the shaft center (the two rings are respectively located at different depth positions as shown in the direction of fig. 4), and the electromagnet 23 and the baffle 25 are respectively connected with one ring, so that the two rings can respectively and independently rotate around the shaft center.

The other small rotating shaft is positioned at the position of the point c, the axle center of the small rotating shaft is fixedly connected with the fixed column, and the ring of the small rotating shaft is sleeved on the axle center and connected with the baffle plate 25, so that the baffle plate 25 can rotate around the point c. The drawings in this embodiment are presented in a manner of the fixed column and two small rotating shafts.

It should be noted that, the shaft center and the ring are both structures of a rotating shaft known to those skilled in the art, and the parts connected with the ring are reserved with space allowed by the rotation of the parts, and in the drawings of the present utility model, the related rotating shaft 24 is not intuitively shown, but the descriptions of the rotating shaft 24 can be defined based on clear technology of the text, and should not be regarded as unclear identification of the technical disclosure.

The one end and the other end are merely expressions of different positions of the electromagnet 23, so that the electromagnet 23 can be driven to rotate around the rotating shaft 24 by the expansion and contraction of the telescopic rod 22 by connecting the telescopic rod 22 and the rotating shaft 24 to different positions of the electromagnet 23 respectively.

According to the embodiment, the movable stop block is arranged on the cargo carrying flat plate of the transfer trolley, so that the movable stop block plays a role in blocking the sliding or dumping of the cargo, and therefore the cargo can be safely transported without fixing the cargo by using ropes.

To ensure that the flaps 25 are not obstructed by the cargo bed 11 when tilted, there are two alternative embodiments:

mode one: the cargo bed 11 is provided with openings 110 to facilitate tilting of the barrier 25 from the position of the openings 110.

Mode two: the movable stopper 2 is provided at an edge position of the loading plate 11, and the shutter 25 protrudes from the outer side of the loading plate 11 to be tilted. This approach does not require modification of the loading ledge 11, but when the flap 25 is level, the flap 25 still protrudes outside the loading ledge 11, which is prone to handling accidents.

The first mode is selected for presentation in the present embodiment and the accompanying drawings.

In practical use, if the baffle 25 is continuously perpendicular to the loading plate 11, it can prevent the cargo from sliding or toppling, but is not beneficial to the normal loading and unloading of the cargo, in order to solve this problem, the present embodiment provides a preferred embodiment, that is, the extended and retracted state of the telescopic rod 22 corresponds to the on-off state of the electromagnet 23, and specifically includes:

when the telescopic rod 22 is extended, as shown in fig. 2 and 4, the electromagnet 23 rotates around the rotating shaft 24 to be perpendicular to the loading plate 11, and the electromagnet 23 is electrified to generate magnetism so as to absorb the baffle 25 to rotate around the rotating shaft 24 to be in a vertical state, so that the baffle is tilted relative to the loading plate 11, and the function of blocking the goods on the loading plate 11 from sliding or tilting is achieved. Fig. 2 and 4 are schematic views of the movable stopper in different directions.

When the telescopic rod 22 is retracted, as shown in fig. 3, the electromagnet 23 rotates around the rotating shaft 24 to be parallel to the cargo bed 11, and the electromagnet 23 is de-energized and de-magnetized to release the barrier 25 to a horizontal state, thereby facilitating loading and unloading of the cargo.

Wherein the telescopic rod 22 is an electric telescopic rod. The control of the expansion and contraction of the telescopic rod 22 is a conventional means in the art, and will not be described in detail herein. In fig. 2, two telescopic rods 22 are provided, and the two telescopic rods 22 are extended and retracted together, so that the electromagnet 23 rotates normally around the axis.

When the electromagnet 23 is energized, the electromagnet 23 generates a magnetic field, attracts the shutter 25 to its tilted position, and clamps the cargo by the magnetic force between the electromagnet 23 and the shutter 25.

When the electromagnet 23 is deenergized, the magnetic force between the electromagnet 23 and the shutter 25 disappears, and the shutter 25 naturally falls back, thereby returning to the horizontal state.

The extension and retraction of the extension rod 22 and the on-off of the electromagnet 23 can be realized by setting a corresponding power supply, a switch for connecting a circuit of the power supply and a control circuit, and controlling the switch by a carrier.

The base 21 is provided with a partial notch so that when the telescopic rod 22 is retracted, the electromagnet 23 rotates to the notch position, and is located below the cargo carrying flat plate 11, and cargo loading and unloading are not affected.

In fig. 4, the respective critical connection points are also identified in the form of arrows, wherein point a identifies the connection location between the telescopic rod 22 and the electromagnet 23, point b identifies the connection location between the electromagnet 23 and the spindle 24, and point c identifies the connection location between the baffle 25 and the spindle 24. It should be noted that, in the present embodiment, the specific connection details between the telescopic rod 22 and the electromagnet 23, the specific connection details between the rotating shaft 24 and the baffle 25, and the detailed structure of the rotating shaft 24 are not shown, but are not represented, but are common knowledge of those skilled in the art, and are omitted from the drawings in order not to affect the presentation of the main bodies of the respective components.

In practical use, in order to ensure the firmness of the cargo fixing, a plurality of movable stoppers 2 are generally used to fix the cargo, for example, the number of the movable stoppers 2 is at least 4.

The direction of transport of the cargo is generally determined by the structural characteristics of the transfer vehicle itself. Taking a manual transfer car as an example, a handle for manual holding is usually provided on the transfer car for pushing or pulling the transfer car forward, and at this time, in order to facilitate manual transportation and application of force, the transportation direction of the goods is usually the direction in which the handle is provided or the opposite direction in which the handle is provided.

In actual use, the movable stoppers 2 can be respectively arranged at four positions of the goods to form omnibearing fixation of the goods.

The base 21 is provided with a screw hole, and the base 21 is fixed at the bottom of the cargo carrying flat plate 11 through the screw hole and a screw matched with the screw hole. The screw holes and screws are not shown in the drawings.

As a preferred embodiment, the side of the electromagnet 23 and the shutter 25 which rotates around the rotation shaft 24 is arc-shaped so that the electromagnet 23 and the shutter 25 rotate.
