[0032] This embodiment discloses a frame structure, a frame assembly and a transport vehicle. First, the frame structure 100 of this embodiment will be introduced.

[0033] As Figure 1As shown in the figure, the frame structure 100 of this embodiment includes longitudinal beams 110 and cross beams 120. Among them, the longitudinal beams 110 are arranged along the first direction, that is, the length direction of the longitudinal beams 110 is configured as the first direction; the cross beams 120 are arranged along the second direction, that is, the length direction of the cross beams 120 is configured as the second direction. Among them, the first direction and the second direction intersect. In this embodiment, it is preferably that the first direction and the second direction are vertically intersecting in the horizontal plane.

[0034] As Figure 2 shown in the figure, in this embodiment, the cross-sections of both the longitudinal beams 110 and the cross beams 120 are open cross-sections. The open cross-section is a well-known term in the art and will not be elaborated here. In this embodiment, the frame structure 100 all uses open cross-section steel beams, which is convenient for cleaning each structural surface and can reduce the structural self-weight at the same time.

[0035] As Figure 3 shown in the figure, in this embodiment, the number of longitudinal beams 110 is two, and the two longitudinal beams 110 are arranged in parallel, and the cross beam 120 is connected to the two longitudinal beams 110.

[0036] As Figure 1 shown in the figure, the longitudinal beam 110 includes a first sub-longitudinal beam 111 and a second sub-longitudinal beam 112, and the first sub-longitudinal beam 111 and the second sub-longitudinal beam 112 are connected together along the first direction.

[0037] As Figure 1 shown in the figure, the second sub-longitudinal beam 112 includes an integrally formed second sub-longitudinal beam body 1211 and a connecting portion 1122. The first sub-longitudinal beam 111 is sleeved on the outer periphery of the connecting portion 1122 (as Figure 4 shown in the figure), and the first sub-longitudinal beam 111 is connected to the connecting portion 1122.

[0038] As Figure 4 shown in the figure, the cross-sectional shape of the first sub-longitudinal beam 111 is the same as that of the connecting portion 1122, but the size specifications are different, so that the first sub-longitudinal beam 111 can be sleeved on the outer periphery of the connecting portion 1122, and the first sub-longitudinal beam 111 is welded to the connecting portion 1122; in this embodiment, the cross-sectional area of the first sub-longitudinal beam 111 is smaller than the cross-sectional area of the second sub-longitudinal beam body 1211 (as Figure 5 shown in the figure), that is, the cross-sectional specification of the first sub-longitudinal beam 111 is smaller than the cross-sectional specification of the second sub-longitudinal beam body 1211. Among them, the second sub-longitudinal beam body 1211 is a variable cross-section beam, and the cross-sectional area at any position of the second sub-longitudinal beam body 1211 is larger than the cross-sectional area of the first sub-longitudinal beam 111.

[0039] As Figure 2As shown, in this embodiment, multiple cross beams 120 are connected in parallel to the longitudinal beam 110. The multiple cross beams 120 are arranged at intervals in the first direction, and the multiple cross beams 120 are parallel to each other. The cross beam 120 is welded to the longitudinal beam 110. Preferably in this embodiment, the number of cross beams 120 is six, which are respectively denoted as the first cross beam 120a, the second cross beam 120b, the third cross beam 120c, the fourth cross beam 120d, the fifth cross beam 120e, and the sixth cross beam 120f.

[0040] Preferably in this embodiment, the cross-sectional shapes of the first sub-longitudinal beam 111 and the second sub-longitudinal beam 112 in the second direction are both C-shaped (similar to the cross-sectional shape of a channel steel). The cross-sectional shape of the first sub-longitudinal beam 111 is as Figure 3 shown, and the cross-sectional shape of the second sub-longitudinal beam 112 is as Figure 5 shown; the cross-sectional shape of the cross beam 120 in the first direction is C-shaped or I-shaped, as Figure 6 shown.

[0041] As Figure 2 shown, preferably in this embodiment, the first cross beam 120a, the second cross beam 120b, the third cross beam 120c, and the fourth cross beam 120d are all arranged on the first sub-longitudinal beam 111, and the fifth cross beam 120e and the sixth cross beam 120f are all arranged on the second sub-longitudinal beam body 1211.

[0042] As Figure 2 and Figure 6As shown, in this embodiment, preferably, the cross-sectional shape of the first cross beam 120a is C-shaped; the cross-sectional shape of the second cross beam 120b is C-shaped, and the structure of the second cross beam 120b is symmetric about the first direction. The upper surface of the second cross beam 120b is a horizontal plane to facilitate the subsequent installation of other structures. The web of the second cross beam 120b is buckled on the longitudinal beam 110, and the second cross beam 120b is partially hollowed out; the cross-sectional shape of the third cross beam 120c is I-shaped, and the third cross beam 120c is a structure symmetric about the left and right of the wing (i.e., symmetric about the first direction). It is formed into a variable cross-section I-shaped cross beam 120 by welding steel plates. In addition, the third cross beam 120c in this embodiment can also directly adopt an I-shaped cross beam 120 with a constant cross-section; the fourth cross beam 120d has the same structure as the second cross beam 120b, and the fourth cross beam 120d and the second cross beam 120b are symmetrically arranged about the third cross beam 120c; the cross-sectional shape of the fifth cross beam 120e is I-shaped, and the structure of the fifth cross beam 120e is symmetric about the left and right in the first direction. The upper and lower surfaces of the fifth cross beam 120e are both large plane structures, which are convenient for placing goods and installing other structures. The fifth cross beam 120e penetrates the second sub-longitudinal beam body 1211 of the two longitudinal beams 110, and a rib plate is arranged in the middle part for local strengthening; the cross-sectional shape of the sixth cross beam 120f is I-shaped, and the structure of the sixth cross beam 120f is symmetric about the left and right in the first direction. The sixth cross beam 120f is welded to the end of the longitudinal beam 110, and a rib plate is arranged in the middle part for local strengthening.

[0043] As Figure 7 shown, this embodiment also discloses a vehicle frame assembly, which includes a limiting mechanism 200 and a vehicle frame structure 100; the limiting mechanism 200 is arranged on the cross beam 120 of the vehicle frame structure 100 for limiting the material bucket 300.

[0044] As Figure 8 shown, in this embodiment, the limiting mechanism 200 includes a limiting plate 210 and a pressing component 220. A plurality of limiting plates 210 are arranged on the cross beam 120 in the circumferential direction for restricting the horizontal displacement of the material bucket 300; the pressing component 220 is arranged on the cross beam 120 for pressing the material bucket 300 against the limiting plate 210 in the horizontal direction. Among them, a plurality of limiting plates 210 are arranged in a horizontal circumferential manner and can form a limiting space. The material bucket 300 is arranged in this limiting space, and the horizontal movement of the material bucket 300 is restricted by the circumferential plurality of limiting plates 210. Among them, the lower surface of the material bucket 300 is supported by the cross beam 120 of the vehicle frame structure 100; the pressing component 220 is arranged on the cross beam 120 and can press the material bucket 300 to prevent the material bucket 300 from shaking or colliding.

[0045] As Figure 8As shown, the limiting mechanism 200 includes three limiting plates 210. The limiting plate 210 includes an arc-shaped vertical plate 211 and a guiding plate 212, and is vertically arranged on the cross beam 120. The guiding plate 212 is obliquely arranged at the upper end of the arc-shaped vertical plate 211. The guiding plate 212 is used to guide the material bucket 300 to fall into the middle of the plurality of limiting plates 210. Among them, the arc-shaped vertical plate 211 has an inner arc surface, and this inner arc surface can match the outer peripheral surface of the material bucket 300 to realize the fitting limit of the material bucket 300. The guiding plate 212 is obliquely arranged, so that the limiting space formed by the plurality of limiting plates 210 has a flared opening at its upper end, and the flared opening can guide the material bucket 300 into the limiting space formed by the plurality of limiting plates 210.

[0046] As Figure 9 shown, in this embodiment, the pressing assembly 220 of the limiting mechanism 200 has two structural forms, and there are two types of limiting mechanisms 200 in this embodiment. The pressing assemblies 220 of the two types of limiting mechanisms 200 can adopt the same structure or different structural forms. In this embodiment, it is preferred that the pressing assembly 220 of the first type of limiting mechanism 200a adopts the first structural form, and the pressing assembly 220 of the second type of limiting mechanism 200b adopts the second structural form. The first type of limiting mechanism 200a is arranged on the second cross beam 120b, the third cross beam 120c and the fourth cross beam 120d, and the second type of limiting mechanism 200b is arranged on the fifth cross beam 120e and the sixth cross beam 120f. Preferably in this embodiment, there are four first type of limiting mechanisms 200a (the four first type of limiting mechanisms 200a are arranged along the horizontal circumferential direction), and there is one second type of limiting mechanism 200b.

[0047] The two structural forms of the pressing assembly 220 are specifically as follows:

[0048] The first structural form, as Figure 8 and Figure 10 shown: The pressing assembly 220 includes a rocker arm 221, a first telescopic member 222, and is used to press the material bucket 300 in the horizontal direction (as Figure 9The first swing positioning plate 223 (shown by the dashed circle in the figure); the first end 2211 of the rocker arm, the telescopic end of the first telescopic member 222 and the first end of the first swing positioning plate 223 are hinged together; the second end 2212 of the rocker arm is hinged to the cross beam 120; a kidney-shaped hole 221a is provided at the third end 2213 of the rocker arm, and a hinge hole is provided on the first swing positioning plate 223, and a connecting pin 221b is inserted into the kidney-shaped hole 221a and the hinge hole; the cylinder end of the first telescopic member 222 is hinged to the cross beam 120, wherein the first telescopic member 222 is configured as a telescopic oil cylinder or a telescopic push rod, etc. (preferably a telescopic oil cylinder in this embodiment), the telescopic direction of the first telescopic member 222 is configured as a horizontal direction, and the cylinder end of the first telescopic member 222 is hinged to the third cross beam 120c (specifically, hinged to the hinge seat at the upper end of the third cross beam 120c); the second end 2212 of the rocker arm is hinged to the support 130 provided on the second cross beam 120b or the fourth cross beam 120d; the first swing positioning plate 223 is located between the two limiting plates 210 and can move towards the center of the limiting space formed by the plurality of limiting plates 210 under the drive of the first telescopic member 222, and one side surface of the first swing positioning plate 223 facing the material bucket 300 can be in close contact with the surface of the material bucket 300.

[0049] In the above first structural form, the problem of the shaking gap of the material bucket 300 is solved by adopting the active clamping method, and the transportation is stable and reliable. And a kidney-shaped hole 221a is provided at the third end 2213 of the rocker arm to adapt to the gap between the material bucket 300 and the limiting plate 210 (specifically, the arc-shaped vertical plate 211), so that the first swing positioning plate 223 can be attached to the outer contour surface of the material bucket 300 and reduce the pressure on the extrusion surface.

[0050] The second structural form, as Figure 11As shown: the clamping assembly 220 includes a swing arm 224, a second telescopic member 225 and a second swing positioning plate 226 for clamping the material barrel 300 in the horizontal direction; the first end 2241 of the swing arm is hinged to the cross beam 120 or the limit plate 210, the second end 2242 of the swing arm is hinged to the telescopic end of the second telescopic member 225, and the third end 2243 of the swing arm is hinged to the second swing positioning plate 226; the cylinder end of the second telescopic member 225 is hinged to the cross beam 120 or the limit plate 210, wherein the overall shape of the swing arm 224 is a triangle, the first end 2241 of the swing arm is hinged to the fifth cross beam 120e or the sixth cross beam 120f, or the first end 2241 of the swing arm is hinged to the third end 2243 of the swing arm set on the limit plate 2 10 The rib plate 213 on the back side is hinged (this method is preferred in this embodiment); the second telescopic member 225 is configured as a telescopic cylinder or a telescopic push rod (preferably a telescopic cylinder in this embodiment), and the cylinder end of the second telescopic member 225 is hinged to the fifth beam 120e or the sixth beam 120f, or the cylinder end of the second telescopic member 225 is hinged to the rib plate 213 on the back side of the limit plate 210 (this method is preferred in this embodiment). When the second telescopic member 225 is extended or retracted, the second swing positioning plate 226 can be driven by the swing arm 224 to move toward or away from the material barrel 300, and the side of the second swing positioning plate 226 facing the material barrel 300 can be in close contact with the material barrel 300.

[0051] In the first and second forms of the clamping assembly 220 of this embodiment, the first form optimizes the stroke of the first telescopic member 222. When the number of transported material barrels 300 is less than four, the first telescopic member 222 at the place without material barrels 300 quickly reaches the screen pressure position, and the first telescopic member 222 at the place with material barrels 300 continues to increase the pressure to the working pressure, and realizes synchronous clamping through oil circuit pressure balance, ensuring that each first swing positioning plate is in reliable contact with the material barrel 300 to reach the clamping state. The second form of the clamping assembly 220 of this embodiment has a compact structure and size, and has little impact on the loading and unloading of the material barrels 300.

[0052] like Figure 9 As shown, in the present embodiment, the limiting plates 210 of the second type of limiting mechanism 200b are each provided with clamping assemblies 220 of the second structural form described above, forming a three-claw form. During the three-claw clamping process, the centering clamping is achieved through the oil circuit pressure balance to ensure reliable contact of the three points. At the same time, a downward force is applied to the material barrel 300 to make the material barrel 300 fit more closely with the frame structure, eliminating the transportation shaking caused by the gap.

[0053] like Figure 9As shown, in this embodiment, a total of four first - type limiting mechanisms 200a and one second - type limiting mechanism 200b are provided. The first - type limiting mechanism 200a adopts the first structural form of the above - mentioned pressing assembly 220, and the second - type limiting mechanism 200b adopts the second structural form of the above - mentioned pressing assembly 220.

[0054] As Figure 12 shown, Figure 12 is the schematic diagram of the hydraulic system of the vehicle frame assembly in this embodiment. Figure 12 In the figure, the dashed - line box C1 represents the first telescopic members 222 of the four first - type limiting mechanisms 200a, and C2 represents the three second telescopic members 225 of the second - type limiting mechanism 200b; P1 represents the first accumulator, P2 represents the second accumulator, K1 represents the first shut - off valve; K2 represents the second shut - off valve, specifically as follows:

[0055] The rod - side cavities of the first telescopic members 222 of the four first - type limiting mechanisms 200a are interconnected, and the rod - less cavities of the first telescopic members 222 of the four first - type limiting mechanisms 200a are interconnected. The pressing of the material bucket 300 is maintained through the first accumulator; the second - type limiting mechanism 200b is provided with a total of three second telescopic members 225. The rod - side cavities of the three second telescopic members 225 are interconnected, and the rod - less cavities of the three second telescopic members 225 are interconnected. The pressing of the material bucket 300 is maintained through the second accumulator. Among them, the first - type limiting mechanism 200a and the second - type limiting mechanism 200b press or release the material bucket 300 through the first shut - off valve and the second shut - off valve respectively. It should be understood that: in this embodiment, the oil - circuit connection design of the multiple first telescopic members 222 and the oil - circuit connection design of the second telescopic members 225 reduce the number of hydraulic components used and lower the operation difficulty of the equipment. The accumulator is used for pressure - maintaining clamping to prevent the loss of the clamping function due to the internal leakage of the valve parts.

[0056] As Figure 13 shown, this embodiment also discloses a transport vehicle. The transport vehicle 1000 includes a vehicle body and a vehicle frame assembly 400; the vehicle frame assembly is arranged on the vehicle body, and the vehicle body can travel on the road surface.

[0057] As described above, only the specific implementation manners of the present application are provided. Those skilled in the art can clearly understand that for the convenience and simplicity of description, the specific working processes of the above - described systems, modules, and units can refer to the corresponding processes in the foregoing method embodiments and will not be repeated here. It should be understood that the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present application.
