For example, the transporter 10 in this embodiment includes a main section chassis 11 and a sub section chassis 12 that are movably disposed.
The opening and closing power mechanism 20 is arranged on the main split chassis 11; the opening and closing supporting leg mechanism 30 is in driving connection with the opening and closing power mechanism 20, the opening and closing supporting leg mechanism 30 is in transmission connection with the auxiliary split chassis 12, and the opening and closing supporting leg mechanism 30 is used for driving the auxiliary split chassis 12 to be close to or far away from the main split chassis 11.
In summary, the embodiment has the following beneficial effects: the transporter 10 adopts a split structure design, namely comprises a main split chassis 11 and an auxiliary split chassis 12 which are split and can be movably arranged, wherein the main split chassis 11 is provided with an opening and closing power mechanism 20, and the opening and closing power mechanism 20 is connected with the auxiliary split chassis 12 through an opening and closing supporting leg mechanism 30. When the material transporting device runs in a wide area, the opening and closing supporting leg mechanism 30 keeps an extending state, and the main split chassis 11 and the auxiliary split chassis 12 are far away from each other (namely, the width of the material transporting device is large), so that the material transporting device is more beneficial to stably loading materials; and when narrow regions such as elevator motor, corridor, room gate are passed through to needs, power unit 20 that opens and shuts starts drive landing leg mechanism 30 that opens and shuts and moves, and landing leg mechanism 30 that opens and shuts drives vice components of a whole that can function independently chassis 12 and is close to main components of a whole that can function independently chassis 11 and move, and the interval between main components of a whole that can function independently chassis 11 and vice components of a whole that can function independently chassis 12 narrows down, and the direct characterization is that the width of material transportation device diminishes to just can be smooth and easy pass through narrow region.

In this embodiment, the main split chassis 11 and the sub-split chassis 12 are both made of metal members, and have a simple structure, high structural strength, strong bearing capacity, low manufacturing cost and convenient later maintenance.
Two moving wheels are arranged at the bottom of the main split chassis 11 and the bottom of the auxiliary split chassis 12 at intervals along the length direction. Namely, the four moving wheels can ensure that the transport vehicle 10 moves stably without inclining and toppling. Optionally, the moving wheel can be a universal wheel and has stronger direction-changing moving capacity.
In some embodiments, the opening and closing power mechanism 20 includes a mounting box 21, an opening and closing driving member, and an opening and closing actuating member, wherein the mounting box 21 is fixed inside the main split chassis 11 and between the main split chassis 11 and the sub-split chassis 12. This helps to reduce the width dimension of the transporter 10.
The opening and closing driving part is arranged in the installation box 21, the opening and closing leg mechanism 30 comprises a first opening and closing leg assembly 31, the opening and closing driving part is in driving connection with the opening and closing actuating assembly, and the opening and closing actuating assembly is used for outputting linear reciprocating power; the first folding leg assembly 31 is rotatably connected with the folding actuating assembly, the mounting box 21 and the auxiliary split chassis 12 respectively, and the first folding leg assembly 31 can be extended or folded. When the opening and closing driving part drives the opening and closing actuating component to output reciprocating linear power, the first opening and closing supporting leg component 31 can be transversely folded or extended to apply pushing force or pulling force to the auxiliary split chassis 12, so that the auxiliary split chassis 12 can be driven to move close to or away from the main split chassis 11 in parallel, and the effect of flexibly adjusting the width of the transport vehicle 10 is achieved.

The motor drives the screw rod 22 to rotate, and the nut 23 can reciprocate on the screw rod 22 along the axial direction under the transmission effect of the thread pair. When the nut 23 moves towards the end of the transport vehicle 10 in the length direction, a pulling force is generated on the first folding leg assembly 31, so that the first folding leg assembly 31 pulls the sub-split chassis 12 to move horizontally close to the main split chassis 11, and the effect of reducing the width of the transport vehicle 10 is achieved. On the contrary, the first foldable leg assembly 31 can push the sub-split chassis 12 away from the main-split chassis 11, so as to achieve the effect of widening the transportation vehicle 10. The screw rod 22 and the nut 23 are adopted for power transmission, so that stable power for parallel movement of the sub-split chassis 12 can be guaranteed.
With reference to fig. 6 and fig. 7, on the basis of the above embodiment, the first foldable leg assembly 31 includes a connecting rod 311 and a foldable leg 312, one end of the connecting rod 311 is rotatably connected to the nut 23, and the other end is rotatably connected to the middle portion or a position near the middle portion of the foldable leg 312; one end of the opening and closing support leg 312 is rotatably connected to the mounting box 21, and the other end is rotatably connected to the sub-split chassis 12.
The pivot connection between the foldable leg 312 and the mounting box 21 can form a fulcrum for the first foldable leg assembly 31 to extend or fold. When the slider 25 slides towards the tail end of the length direction of the transport vehicle 10, the connecting rod 311 is pulled to rotate, the connecting rod 311 synchronously pulls the opening and closing supporting legs 312 to rotate inwards, and at the moment, the opening and closing supporting legs 312 are gradually close to the connecting rod 311 in parallel, so that the auxiliary split chassis 12 is close to the main split chassis 11, and the width of the transport vehicle 10 is adjusted to be reduced. Conversely, the width of the transporter 10 can be adjusted to be larger. That is, the link 311 and the opening/closing leg 312 are rotated to be extended or folded, and the movement stroke is short, so that the sub-body chassis 12 can be driven to move closer to or away from the main body chassis 11 more quickly, and the width adjustment efficiency of the transporter 10 is improved.
With reference to fig. 6 and fig. 7, further, the opening/closing actuation assembly further includes a guide rail 24 and a slider 25, the guide rail 24 is disposed on the main split chassis 11, and the slider 25 is disposed on the nut 23 and slidably disposed on the guide rail 24.

The second leg assembly 32 also includes a connecting rod 311 and a leg 312, and is hinged to the other nut 23 of the screw rod 22 and the mounting box 21. After the motor is started, the two nuts 23 synchronously move in the opposite directions, and the first opening-closing leg assembly 31 and the second opening-closing leg assembly 32 synchronously move in an extending or folding manner, so that the auxiliary split chassis 12 is subjected to more balanced opening-closing driving force, and the good width adjustment consistency of the transport vehicle 10 is ensured.
In addition, on the basis of any of the above embodiments, the material transportation device further includes an energy storage battery, and the energy storage battery is disposed on the main split chassis 11 and electrically connected to the opening and closing power mechanism 20. The energy storage battery provides electric energy for the motor, and the sustainable operation capability of the material transportation device is improved.
