[0041] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0042] This embodiment provides a bearing device for an axle, which makes structural improvements on the fixed shape of a conventional axle transport frame welded with pipes. The new structure can have both folding and stacking positioning functions, greatly improving practicality.

[0043] Please refer to Figure 1 , Figure 1 The specific structure of a bearing device provided by the present embodiment is shown, which includes a base 1, a plurality of corner columns 2, a plurality of bearing frames 3 and a plurality of supporting legs 4. The plurality of corner columns 2 are arranged at intervals along the periphery of the base 1 and protrude upward from the base 1; the plurality of bearing frames 3 are arranged above the base 1, and the two ends of the bottom of each bearing frame 3 are respectively connected to the two corner columns 2 for rotation, and the bearing frames 3 can be erected on the upper surface of the base 1 to carry the axle, or rotated inward to be folded on the base 1; the plurality of supporting legs 4 are protrudingly arranged below the base 1, and correspond to the plurality of corner columns 2 one by one up and down; the lower end of the supporting leg 4 is hollow inside to form a receiving groove, and the shape and size of the receiving groove are not less than the outer dimensions of the upper end of the corner column 2.

[0044] Please combine Figure 2 The cross section of the base 1 is annular and lightweight.

[0045] Specifically, the base 1 includes two main bodies 11 and two transition parts 13. Each main body 11 is arc-shaped, similar to a C-shaped structure. The arc-shaped openings of the two main bodies 11 are opposite to each other and are symmetrically arranged. The two transition parts 13 are arranged between the openings of the two main bodies 11, and each transition part 13 is respectively connected to one end of the opposite openings of the two main bodies 11 to jointly enclose a ring structure. The outer contour of the ring structure is a rectangle, and the inner contour is a rounded rectangle with rounded corners. The inner hollow part of the base 1 is large, and the overall weight is light. It is convenient to carry and move when the strength is qualified, thereby improving transportation efficiency.

[0046] In this embodiment, the main body 11 and the transition part 13 are both sheet metal parts integrally formed by stamping, which adopts a stamping forming process and has the advantages of being lightweight and having low labor costs.

[0047] In addition, the base 1 adopts a stamping process, which is highly modular and automated. Compared with the traditional transport rack formed by welding, it has the following advantages: it can be manufactured and delivered remotely (it can be produced in multiple locations and assembled and delivered in a centralized manner); it reduces the welding workload (using mold stamping and forming, mass production efficiency is high, and the corresponding welding process is reduced); it improves the reuse rate. Since the product adopts an assembled and modular design, if the vehicle model is upgraded, most of the components can still be reused, and only some components need to be replaced.

[0048] The main body portion 11 and the transition portion 13 both include a horizontal plate body 111 and a flange 112 bent vertically downward from the periphery of the plate body 111 .

[0049] Please combine Figure 3 In order to improve the strength of the main body 11, a plurality of reinforcing plates 113 are integrally formed on the main body 11. The plurality of reinforcing plates 113 are arranged below the main body 11 and are spaced apart and parallel along the long sides of the main body 11. Each reinforcing plate 113 is vertically connected to the inner flange 112 and the outer flange 112 of the main body 11. At the same time, the inner and outer flanges 112 of the short sides of the main body 11 are flushly connected to the inner and outer flanges 112 of the transition portion 13.

[0050] Please return to Figure 1 The lower edge of the flange 112 of the main body 11 also has a fork groove 101 that opens downward, and the fork groove 101 is for the fork of the forklift to extend into, so as to achieve the lifting, hoisting and transportation of the load-bearing device. In addition, the load-bearing device is further provided with a reinforcing rod 6 corresponding to the fork groove 101 to improve the structural strength. There is a gap between the reinforcing rod 6 and the flange 112 for the fork to pass through.

[0051] Furthermore, the upper surface of the transition portion 13 is lower than the upper surface of the main body portion 11 and is recessed to form a groove 103 .

[0052] Furthermore, the bearing device further includes two gaskets 5. Each gasket 5 is correspondingly accommodated in a groove 103 of each transition portion 13, and is used to abut against the bottom of the bearing frame 3 when the bearing frame 3 is vertical. At the same time, the transition portion 13 is provided with a positioning hole 105 at the groove 103, and the gasket 5 is provided with a corresponding hole for the positioning member 8 to be inserted to keep the bearing frame 3 in a vertical state.

[0053] Please refer to Figure 4The rotation connection between the corner column 2 and the supporting frame 3 is as follows: a through hole 201 is provided at the upper end of the corner column 2 beyond the base 1. Connecting holes corresponding to the through holes 201 of the two corner columns 2 are respectively provided at both ends of the bottom of the supporting frame 3, and the supporting frame 3 is hingedly connected to the corner column 2 by passing through the through holes 201 and the connecting holes through the matching fasteners.

[0054] Specifically, there are four corner columns 2 , which are respectively disposed at four corners of the base 1 .

[0055] Each corner column 2 includes two side panels 21 connected at an angle, and the two side panels 21 are respectively fixed to two adjacent outer side surfaces (i.e., flanges 112) of the base 1, and the upper end of the side panel 21 extends upward beyond the upper surface of the base 1, and the lower end of the side panel 21 also extends downward beyond the bottom of the base 1. The space enclosed by the two side panels 21 is used to accommodate the end of the carrier 3.

[0056] The two side panels 21 have different shapes, and for the convenience of description, they are respectively defined as a first side panel 211 and a second side panel 212 .

[0057] The width of the first side plate 211 along the horizontal direction decreases and increases from top to bottom through an arc transition. The upper end of the first side plate 211 is provided with a through hole 201 extending vertically, and the lower end thereof is provided with a hook hole 203 extending vertically. It is worth noting that the hook hole 203 and the through hole 201 are arranged in an up-and-down staggered manner, that is, the hook hole 203 is located at a portion of the first side plate 211 with a larger width to avoid stress concentration. The shape of the hook hole 203 is similar to a disc cam, while the through hole 201 is a long hole.

[0058] Furthermore, two ends of the reinforcing rod 6 are respectively connected to the inner sides of the lower ends of two adjacent first side plates 211 .

[0059] The second side plate 212 is shaped like a convex letter, and its tip is aligned and fitted with the flange 112 of the base 1. The second side plate 212 is symmetrically arranged with respect to the base 1. No holes are provided on the second side plate 212 to ensure the strength of the connection.

[0060] Furthermore, the corner column 2 also includes a baffle 23 .

[0061] The baffle 23 is erected on the upper surface of the base 1 and is vertically connected and fixed to the second side plate 212. The baffle 23 is spaced relatively from the first side plate 211, and the upper end of the baffle 23 is flush with each side plate 21. The baffle 23 is provided with a long strip-shaped through hole 201 corresponding to the first side plate 211. The baffle 23, the first side plate 211, the second side plate 212 and the base 1 define a limiting cavity with a rectangular cross-section, and the limiting cavity is used to accommodate the end of the limiting bearing frame 3. The limiting cavity has an opening. The openings of the corner columns 2 arranged on both sides of the base 1 are opposite to each other on the left and right, and any bearing frame 3 can be turned 90 degrees to the inside of the base 1 through the opening and folded on the base 1.

[0062] It is worth noting that a limiting hole is recessed at the upper end of the first side plate 211 and the baffle plate 23 .

[0063] Please refer to further Figure 5 The bearing device further comprises four limit plates 7. The four limit plates 7 are arranged at each corner column 2 in a one-to-one correspondence.

[0064] Specifically, the limiting plate 7 is vertically arranged at the opening of the corner column 2, and the two ends of the limiting plate 7 are connected to the inner side of the first side plate 211 and the baffle 23. The limiting plate 7 is a small rectangular plate, and the upper end of the limiting plate 7 is much lower than the upper end of the first side plate 211, which facilitates the flipping of the supporting frame 3. When the supporting frame 3 flips toward the inner side of the base 1, the bottom end of the supporting frame 3 overlaps the limiting plate 7.

[0065] When the bottom end of the support frame 3 falls from above into the limiting cavity of the corner column 2, the end face of the bottom end fits against the upper surface of the base 1, and at the same time, the four side faces of the bottom end respectively fit against the inner side faces of the first side plate 211, the second side plate 212, the baffle plate 23 and the limiting plate 7 in a one-to-one correspondence, thereby preventing the support frame 3 from flipping over and maintaining its vertical supporting state.

[0066] Please refer to Figure 6 , the number of the carriers 3 is two. The two carriers 3 are arranged oppositely on the two sides of the base 1. Positioning holes 105 are respectively provided on the two side edges of the base 1, and each carrier has a through hole corresponding to the positioning hole 105 for the positioning member 8 to be inserted and fixed to increase the connection strength.

[0067] Each supporting frame 3 includes two columns 31 and a supporting structure 32 transversely arranged between the two columns 31 .

[0068] Two columns 31 are arranged at intervals on the same side edge of the base 1. Each column 31 stands upright above the base 1 and is received in the limiting cavity of the corner column 2. The opposite sides of the column 31 are respectively fitted with the inner sides of the first side plate 211 and the baffle 23, and the column 31 is provided with a connecting hole opposite to the through hole 201. The matching fasteners such as the pin shaft are inserted into the through hole 201 and the connecting hole in sequence, so that the rotation connection between the column 31 and the corner column 2 can be realized.

[0069] The upper end of the column 31 exceeds the upper surface of the bearing structure 32, and the upper ends of the two columns 31 and the upper surface of the bearing structure 32 define a bearing groove opening upward; the bearing groove is used to accommodate a horizontally placed vehicle axle.

[0070] In addition, two limit blocks 25 are respectively disposed on both sides of each column 31 ; the two limit blocks 25 are respectively opposite to the first side plate 211 and the baffle plate 23 .

[0071] The limit block 25 extends vertically and is used to limit the vertical position of the support frame 3. The limit block 25 is a small plate-like structure, and its circumferential size is roughly the cross-sectional area of ​​the column 31. The lower end of the limit block 25 is a tip, which is removably embedded in the limit hole on the top of the first side plate 211 (baffle 23). The two limit blocks 25 are used to cooperate with the corner column 2 when the support frame 3 is vertical, so as to further limit the relative displacement of the support frame 3 in the horizontal direction from both sides, ensuring that the support frame 3 is in a stable vertical working state.

[0072] The bearing structure 32 includes a cross beam 321 , a positioning beam and two support members 324 .

[0073] The cross beam 321 is horizontally connected to the middle of the two upright posts 31 to form an “I”-shaped structure.

[0074] The two support members 324 are located at two ends of the crossbeam 321 and are vertically connected to the lower surface of the crossbeam 321 .

[0075] The positioning beam 322 is connected to one end of the two support members 324 away from the cross beam 321, and is spaced parallel to the cross beam 321. The positioning beam 322 extends in the horizontal direction. A through hole compatible with the positioning hole 105 is provided through the middle of the positioning beam 322. The positioning beam 322 is used to fit the upper surface of the base 1 when the support member 324 (column 31) is vertical. At this time, the positioning beam 322 abuts against the gasket 5 in the groove 103 of the transition part 13, and the through hole, the hole of the gasket 5 and the positioning hole 105 of the transition part 13 are opposite to each other so that the positioning member 8 can be passed from top to bottom. The vertical arrangement of the positioning member 8 connects the support frame 3 and the base 1 together, improves the connection strength, and keeps the support frame 3 in a vertical working state.

[0076] Preferably, the upright column 31, the cross beam 321, the support member 324 and the positioning beam 322 are all square tubes. The square tube has a high degree of standardization and modularization, can be installed according to actual conditions, and has high versatility.

[0077] Furthermore, the supporting frame 3 also includes two buffer pads 36 .

[0078] The two buffer pads 36 are laid flat on the upper surface of the cross beam 321 and are spaced apart at both ends of the cross beam 321 to independently support the axle.

[0079] At the same time, a support member 324 is correspondingly disposed below each buffer pad 36. The support member 324 can provide vertical support force for the buffer pad 36 to improve the stability of the load.

[0080] The buffer pad 36 is concave in shape, and the middle groove of the buffer pad 36 is used to limit the axle. One end of the buffer pad 36 abuts against the side wall of the column 31, and the other end abuts against the stop block 37 to prevent displacement. At the same time, the buffer pad 36 is provided with two screws at intervals along its length direction, and is connected and fixed to the crossbeam 321 by screws. Preferably, the buffer pad 36 is made of polyurethane material, which has light weight and shock absorption effect.

[0081] Please continue to refer to Figure 6 The supporting foot 4 includes a supporting column 41 and a foot pad 43 .

[0082] The support column 41 is protruding from the lower surface of the base 1 , and the adjacent two sides of the support column 41 are respectively connected and fixed to the inner side surfaces of the first side plate 211 and the second side plate 212 . The lower end of the support column 41 is flush with the lower end of each side plate 21 .

[0083] The foot pad 43 is protruding from the lower end of the support column 41. The foot pad 43 is a hollow cylindrical structure, and the inner cavity of the foot pad 43 is a receiving groove. The shape and size of the receiving groove are adapted to the outer size of the upper end of the corner column 2, and are used to receive the upper end of the corner column 2.

[0084] Preferably, the foot pad 43 is gradually expanded from top to bottom. The cross section of the foot pad 43 is rectangular. The lower end of the foot pad 43 has the largest diameter, so that the corner column 2 can be easily aligned and enter the inside of the foot pad 43 during stacking. The outer dimensions of the upper end of the corner column 2 are consistent with the outer dimensions of the smallest cross section of the foot pad 43, that is, the upper end of the corner column 2 can extend upward to the innermost part of the foot pad 43 to prevent the corner column 2 from detaching from the foot pad 43.

[0085] Please combine Figure 7 During use, when multiple load-bearing devices are stacked up and down, at this time, the two load-bearing frames 3 of each load-bearing device are folded and laid flat on the base 1, and there is a certain distance between the two load-bearing frames 3. Among them, the corner column 2 of the load-bearing device located at the bottom protrudes upward from the base 1, and correspondingly extends into the receiving groove of the support foot 4 just above, so as to achieve stacking positioning in the vertical direction. Multiple load-bearing devices are stacked layer by layer according to the above stacking method. As the weight increases, the upper and lower adjacent corner columns 2 and the support foot 4 are more closely embedded, and a firm and stable connection relationship can be achieved without other auxiliary fixing devices.

[0086] In summary, the load-bearing device of a vehicle bridge provided by the present invention has at least the following advantages and positive effects:

[0087] Firstly, the support frame 3 is rotatably connected to the corner column 2, and can be erected on the base 1 to support the axle when needed, or can be folded on the base 1 during transportation to save space.

[0088] Secondly, a plurality of support legs 4 corresponding to the corner columns 2 are arranged on the base 1, and the support legs 4 have receiving grooves capable of accommodating the upper ends of the corner columns 2. When multiple load-bearing devices are stacked up and down, the support frame 3 of each load-bearing device is folded, and the corner columns 2 of the load-bearing device located below protrude upward from the base 1 and extend into the receiving grooves of the support legs 4 of the load-bearing device directly above, thereby realizing stacking positioning in the vertical direction. Multiple load-bearing devices are stacked layer by layer according to the above stacking method. As the weight increases, the upper and lower adjacent corner columns 2 and support legs 4 are more closely fitted, and a firm and stable connection relationship can be achieved without other auxiliary fixing devices.

[0089] Finally, the base 1 includes two main bodies 11 and two transition parts 13. Each main body 11 is arc-shaped, similar to a C-shaped structure. The arc-shaped openings of the two main bodies 11 are opposite and symmetrically arranged. The two transition parts 13 are arranged at the openings of the two main bodies 11, and each transition part 13 is respectively connected to one end of the opposite opening of the two arc-shaped parts to form a ring structure together. The main body 11 and the transition part 13 are both sheet metal parts formed by stamping. They adopt a stamping molding process and have the advantages of lightweight and low labor cost.
