[0019] The present application provides an auxiliary transportation device, such as Figures 1-8 As shown, it comprises a loading mechanism 200, an adjusting mechanism 300 and a walking mechanism 100, the loading mechanism 200 comprises a bottom compartment 210 and an upper compartment 220 arranged on the bottom compartment 210, the upper compartment 220 comprises adjustable side guardrails 221 and end guardrails 222; the adjusting mechanism 300 is arranged on the loading mechanism 200, the adjusting mechanism 300 comprises a plurality of support plates, the plurality of support plates can be in a horizontal state to form a horizontal support space for accommodating transverse materials, at least one support plate can be turned over to expose the bottom compartment 210 to form a vertical support space for accommodating vertical materials; the walking mechanism 100 is arranged on both sides of the loading mechanism 200, the walking mechanism 100 comprises a wheel frame 111 and a driving mechanism and a walking wheel 112 arranged on the wheel frame 111.

[0020] The auxiliary transportation device provided by the embodiment can flexibly adapt to the transportation requirements of materials of different sizes and shapes through the structure of the bottom compartment 210 and the upper compartment 220 of the loading mechanism 200, in cooperation with the adjustable side guardrails 221 and the end guardrails 222. The adjusting mechanism 300 can form a stable horizontal support surface to transport transverse materials, and can also be quickly converted into a vertical support mode through the overturning of the support plates, so as to meet the special transportation requirements of vertical materials, realize multi-scene transportation function, and ensure the stable moving ability in complex terrain through the symmetrical arrangement of the walking mechanism 100 on both sides of the loading mechanism 200, thereby significantly improving the applicability and operation efficiency of the transportation device, reducing the manual intervention and operation difficulty, and being especially suitable for industrial transportation scenes with limited space or variable material forms.

[0021] In an implementable manner, as shown in Figures 4-8 The side guardrails 221 and the end guardrails 222 are arranged opposite to each other on the bottom compartment 210, the side guardrails 221 can be switched between the vertical state and the horizontal state, and the end guardrails 222 can be switched between the vertical state and the lowered state.

[0022] Among them, the side guardrails 221 and the end guardrails 222 are arranged opposite to each other on the bottom compartment 210, and multi-functional transportation is realized through double-state switching, as shown in Figure 6 and Figure 7 The side guardrails 221 in the vertical state can provide side protection, as shown in Figure 8 The side guardrails 221 in the horizontal state can expand the loading platform, as shown in Figure 6 and Figure 7 The end guardrails 222 in the vertical state can fix the end materials, as shown in Figure 8 The end guardrails 222 in the lowered state can load larger materials, for example, moving trains, and facilitate loading and unloading operations; through the adjustment of the side guardrails 221 and the end guardrails 222, the fixing requirements of materials of different forms can be met, and various transportation scenes can be adapted through state combination, thereby significantly improving the loading safety and space utilization.

[0023] In an implementable manner, as shown in Figures 4-8 The side guardrails 221 are hinged between the bottom compartment 210, the end guardrails 222 are hinged between the bottom compartment 210, and the side guardrails 221 and the end guardrails 222 are in the vertical state and are locked through the locking member; after the side guardrails 221 and the end guardrails 222 are unlocked, the wheel frame 111 supports the side guardrails 221 to keep the horizontal state, and the end guardrails 222 are overturned to the lowered state.

[0024] Among them, as shown in Figure 6 and Figure 7As shown, the two-way state conversion of the side guardrail 221 and the end guardrail 222 is realized through the hinged structure. When the side guardrail 221 and the end guardrail 222 are both in the vertical state, rigid fixation is formed between them through the locking piece, ensuring the structural stability during transportation. Figure 8 As shown, after unlocking, the side guardrail 221 is supported by the wheel frame 111 to remain horizontal, expanding the loading platform area, and the end guardrail 222 can be flipped to the down state to avoid interference with long materials, ensuring transportation safety and improving operational convenience. At the same time, through the support design of the wheel frame 111 to the side guardrail 221, the space occupation of the additional support structure is avoided, enabling the device to realize multifunctional adaptation in limited space.

[0025] In one implementation, as shown in Figure 4 and Figure 5 The adjustment mechanism 300 includes a first support plate 310 and second and third support plates 320 and 330 respectively arranged on both sides of the first support plate 310. The second support plate 320 is hinged to one end of the first support plate 310, and the third support plate 330 is hinged to the other end of the first support plate 310. The first support plate 310 and the second support plate 320 can be flipped to expose the space inside the bottom compartment 210.

[0026] Among them, through the hinged design of the first support plate 310 and the second and third support plates 320 and 330, flexible conversion of the space form is realized. When the second and third support plates 320 and 330 are flipped onto the first support plate 310, the space inside the bottom compartment 210 can be quickly expanded, facilitating the placement of the battery box 118 or forming a vertical loading area for standing higher materials such as vertical heavy-duty water pumps, and reducing the distance between the placement surface and the ground, facilitating cargo loading and unloading, especially suitable for underground spaces with insufficient lifting height.

[0027] Among them, when multiple support plates are in a horizontal state, they collectively form a stable load-bearing surface to meet the demand for laying transverse materials such as long and heavy oil cylinders, ensuring structural stability during transportation and improving loading efficiency through space optimization, especially suitable for complex operation scenarios that require frequent switching of material forms.

[0028] It can be understood that the material placement box can realize three forms according to different material transportation needs. As shown in Figure 6 the side guardrail is erected to transport slender materials such as anchor rods and oil cylinders; Figure 7 As shown, the third support plate 330 is opened to stand materials such as water pumps, and the lower chassis facilitates manual handling of materials on and off the vehicle; Figure 8 As shown, the side guardrail 221 is laid flat to place wide materials such as mesh, which can meet the needs of auxiliary transportation of different shapes of materials in limited space.

[0029] In an embodiment, as shown in Figure 4 The detachable supporting rod 331 is arranged on the bottom compartment 210 to support the third supporting plate 330 to keep it in a horizontal state.

[0030] The detachable supporting rod 331 is in a welded structure of a square tube and a U-shaped bending piece, is quickly installed on the bottom compartment 210 by buckling, provides stable support for the third supporting plate 330, is rigidly connected with the bottom compartment 210 through the square tube, ensures the structural strength of the third supporting plate 330 in the horizontal state, and is designed with a buckle of the U-shaped bending piece, which facilitates quick disassembly and assembly, effectively prevents displacement of the supporting plate during transportation, and simplifies the operation process of switching the supporting mode.

[0031] In an embodiment, as shown in Figures 1-8 The bottom compartment 210 includes a first bottom plate, a second bottom plate and a third bottom plate arranged on both sides of the first bottom plate, and a surrounding vertical plate. The control box 117 is arranged between the first bottom plate and the first supporting plate 310. The battery box 118 is arranged between the second bottom plate and the second supporting plate 320. The third bottom plate is provided with a sunken space for accommodating vertical materials.

[0032] The bottom compartment 210 is designed in a multi-bottom plate structure with different heights. The first bottom plate, the second bottom plate and the third bottom plate are arranged in different ways to adapt to multiple scenes. The control box 117 is arranged between the first bottom plate and the first supporting plate 310. The sunken space formed between the second bottom plate and the second supporting plate 320 is used to accommodate the battery box 118. The sunken space formed above the third bottom plate is used to accommodate vertical materials. When vertical heavy materials are loaded, the vertical heavy materials and the battery box 118 are arranged on both sides of the control box 117 in a symmetrical manner, which improves the transportation stability through weight distribution optimization.

[0033] In an embodiment, as shown in Figure 2 The first bottom plate is arranged above the second bottom plate and the third bottom plate.

[0034] The stepped difference between the first bottom plate and the second bottom plate and the third bottom plate forms a natural anti-skid structure, which, together with the surrounding vertical plate, can effectively constrain the displacement of the battery box 118 and the vertical materials. The sunken space design of the second bottom plate and the third bottom plate provides independent embedded accommodation structure for the battery box 118 and the vertical materials, which, together with the first bottom plate and the surrounding vertical plate, can effectively prevent the risk of overturning during transportation. The function partitioning improves the loading efficiency and optimizes the space utilization.

[0035] In an embodiment, as shown in Figure 2As shown, the first bottom plate is provided with a rotating shaft 114 and a pull rod mechanism 115, the bottom compartment 210 is connected with the wheel frame 111 through the rotating shaft 114, and the pull rod mechanism 115 is arranged on the bottom compartment 210 to form a transverse connection.

[0036] Wherein, the first bottom plate is provided with a shaft sleeve, the rotating shaft 114 is arranged in the shaft sleeve, and both ends are connected with the wheel frame 111, connecting the loading mechanism 200 and the walking mechanism 100 to form a whole, and moving the loading mechanism 200 to transport materials through the walking mechanism 100.

[0037] Wherein, the transverse connection of the pull rod mechanism 115 to the bottom compartment 210 forms a rigid constraint network, which can not only disperse the torsional stress of the bottom compartment 210, but also enhance the anti-deformation ability of the overall structure.

[0038] Further, the rotating shaft 114 and the pull rod mechanism 115 are arranged between the first bottom plate and the second bottom plate, which reduces the space requirement in the vertical direction, meets the space limitation of warehouse transportation, and also reduces the direct damage of external complex environment to the mechanical structure.

[0039] In an embodiment, as shown in Figure 2 The walking mechanism 100 further includes a coulomb meter 113 and an explosion-proof button box 116, the coulomb meter 113 is arranged on the wheel frame 111 and is used to display the remaining power of the battery box 118, and the explosion-proof button box 116 is arranged on the wheel frame 111, and the explosion-proof button box 116 includes forward, backward and emergency stop buttons.

[0040] Wherein, the coulomb meter 113 is used as a real-time monitoring terminal of the battery box 118, and the signal transmission path is shortened through the layout integrated in the wheel frame 111, so as to ensure the immediacy and accuracy of the power display.

[0041] Wherein, the explosion-proof button box 116 adopts an explosion-proof structure to encapsulate control instructions, and the forward / backward / emergency stop functions thereof are designed through mechanical interlocking to avoid misoperation, and meet the protection standard of electrical equipment in dangerous environment.

[0042] In an embodiment, the auxiliary transportation device further includes a control system, the control system includes a remote control device and a wireless receiving module, and the control box 117 integrates the wireless receiving module and is used to realize remote control through the remote control device.

[0043] Wherein, the control system of the auxiliary transportation device integrates the wireless receiving module through the control box 117, ensures the anti-interference transmission of the remote control instruction in the complex industrial environment, realizes multi-channel signal isolation through the encoder-decoder architecture of the remote control device, can also switch the manual / remote control mode in real time, and is suitable for harsh working conditions such as mine transportation.
