It should be noted that the structure, proportion, size, etc. illustrated in the drawings of this specification are only used to match the content disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no technical substantive significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effect that the present invention can produce and the purpose that can be achieved, should still fall within the scope of the technical content disclosed by the present invention.

The first supporting mechanism 4 is arranged on the surface of the bottom plate 3, the first adjusting mechanism 5 cooperates with the bottom frame 1 to adjust the height of the bottom frame 1 from the ground to adapt to different environments, and the second adjusting mechanism 6 is located between the bottom plate 3 and the second supporting mechanism 8 and cooperates with the bottom plate 3 and the second supporting mechanism 8 respectively, that is, to adjust and control the distance between the bottom plate 3 and the second supporting mechanism 8. A pushing component 9 is also provided on the surface of the bottom frame 1, and the pushing component 9 includes a push rod 901 and a control member 902. The push rod 901 is rotatably matched with the bottom frame 1, and the control member 902 is matched with the push rod 901. The push rod 901 is rotated relative to the bottom frame 1 by regulating the control member 902, thereby pushing the top loading vehicle structure forward.

[0033] Please continue reading Figures 2 to 6 The first support mechanism 4 includes a first support portion 401, a first adjustment component 402 and a second adjustment component 403. The second adjustment component 403 is respectively matched with the first support portion 401 and the first adjustment component 402. The first adjustment component 402 realizes the synchronous movement of the second adjustment component 403 and the first support portion 401 relative to the first adjustment component 402, and the second adjustment component 403 realizes the movement of the first support portion 401 relative to the first adjustment component 402 and the second adjustment component 403.

[0034] Specifically, the first support part 401 includes a support 4011, a bearing 4012 and a clamping member 4013, wherein the bearing 4012 is connected to the support 4011 and is used to carry an object, and the clamping member 4013 is rotatably connected to the support 4011 and symmetrically arranged with respect to the bearing 4012, and the first support part 401 also includes a plug plate 4014, and the plug plate 4014 can be movably matched with the clamping member 4013. Preferably, in this embodiment, two first support mechanisms 4 are arranged on the surface of the bottom plate 3, and two clamping members 4013 are arranged on each of the first support mechanisms 4 to match the bearing 4012 to clamp an object, thereby improving the stability of the bearing 4012 when carrying an object. After the clamping member 4013 is rotated and adjusted, the plug plate 4014 is fixed to the support 4011 with the aid of a latch, and at the same time, the clamping member 4013 is limited to prevent the clamping member 4013 from rotating after clamping an object.

[0035] Furthermore, the first adjustment component 402 includes a base 4021, a first moving block 4022, and a second moving block 4023. The base 4021 is arranged on the bottom plate 3. The first moving block 4022 is movably matched with the base 4021 and is symmetrically arranged about the base 4021. The second moving block 4023 is arranged on the base 4021 and is located between the first moving blocks 4022. The first moving block 4022 has a first inclined surface 40221, and the second moving block 4023 has a second inclined surface 40231. The first inclined surface 40221 is matched with the second inclined surface 40231.

[0036] Further, the first adjustment component 402 also includes a first adjustment member 4024, a first screw rod 4025 and a fixed block 4026, wherein the fixed block 4026 is arranged on the base 4021, the first screw rod 4025 is respectively matched with the first moving block 4022 and the fixed block 4026, and one end of the first screw rod 4025 is also connected to the first adjustment member 4024. The first screw rod 4025 is rotated by adjusting the first adjustment member 4024. Since the fixed block 4026 is fixed on the base 4021, the first moving block 4022 moves under the action of the first screw rod 4025. Preferably, in this embodiment, when the symmetrically arranged first moving blocks 4022 move closer to each other, the second moving block 4023 is lifted, and when the symmetrically arranged first moving blocks 4022 move away from each other, the second moving block 4023 is lowered. There is also a scale on the surface of the second moving block 4023, which is convenient for users to accurately control the adjustment amount.

[0037] Further, the second adjustment component 403 includes a second adjustment member 4031, a second screw rod 4032 and a movable block 4033, wherein the movable block 4033 is connected to the support 4011, and the support 4011 can be movably matched with the second moving block 4023, the second screw rod 4032 is respectively matched with the second moving block 4023 and the movable block 4033, and one end of the second screw rod 4032 is also connected to the second adjustment member 4031. The second screw rod 4032 is rotated by adjusting the second adjustment member 4031. Since the second moving block 4023 is relatively stationary during the adjustment of the second adjustment component 403, the movable block 4033 is connected to the support 4011, so that the movable block 4033 is displaced with the rotation of the second screw rod 4032, thereby driving the support 4011 to move, i.e., the first support portion 401 is displaced, and in this embodiment, the horizontal displacement adjustment relative to the length direction of the second screw rod 4032 is performed. The surface of the support 4011 is also provided with scales to facilitate the user to precisely control the adjustment amount.

Figure 7As shown, by adjusting the relative position of the third adjusting member 5042 and the fixing member 5041, and fixing with a bolt or other device, the height of the bottom frame 1 from the ground can be adjusted and controlled. Specifically, when the third adjusting member 5042 is located at the end of the fixing member 5041 away from the moving assembly 7, the height of the connecting plate 501 is the lowest, that is, the height of the bottom frame 1 connected to the connecting plate 501 is the lowest. On the contrary, when the third adjusting member 5042 is located at the end of the fixing member 5041 close to the moving assembly 7, the height of the connecting plate 501 is the highest, that is, the height of the bottom frame 1 connected to the connecting plate 501 is the highest. In this embodiment, four first adjusting mechanisms 5 and corresponding four moving assemblies 7 are provided on the bottom frame 1, and then the height of the bottom frame 1 from the ground can be adjusted and controlled as needed through the first adjusting mechanism 5, and the walking of the top loading vehicle structure of this embodiment is achieved through the moving assembly 7.

When the locking member 60221 does not act on the sliding block 6022 and the first rod 6021, the fourth adjustment assembly 602 can be driven to move along the said by moving the end plate 6024. When the sliding block 6022 contacts the second stopper 6023, the maximum movement distance of the fourth adjustment assembly 602 is reached, which is also the maximum expansion length of the second adjustment mechanism 6. When the end plate 6024 contacts the first stopper 601 and the end of the first rod 6021 away from the bottom plate 3, it is the minimum expansion length of the second adjustment mechanism 6.
