The limiting frame is of an L-shaped structure, the top wall of the limiting frame is tangent to the supporting shaft, and a second pushing cylinder is fixed at the connection between the outer side wall of the vertical end of the limiting frame and the side wall of the support frame.

[0009] Preferably, a limiting end plate is fixed on the side of the top outer wall of the limiting frame away from the driving motor, the limiting end plate is an L-shaped structure, and the outer wall of the vertical end of the limiting end plate is close to one end of the support shaft.

[0010] Preferably, mounting blocks are fixed on the inner side walls around the flip frame, a hydraulic push rod is fixed on the mounting block, and a fixing block is fixedly connected to the hydraulic push rod.

[0011] Preferably, the longitudinal sections of the card block and the card slot are both polygonal.

The following will further describe the present utility model in detail in conjunction with the accompanying drawings.

[0020] As Figure 1-4 shown, a kind of excavator platform flipping processing tooling proposed by the present utility model includes a support bottom plate 1. A flipping frame 2 is placed on the support bottom plate 1. The flipping frame 2 is square. Connecting rods 3 are fixed on the outer side wall of the flipping frame 2. The connecting rods 3 are arranged on two adjacent sides of the flipping frame 2. A support shaft 4 is fixed at one end of the connecting rod 3. A support frame 5 is arranged under the support shaft 4. The support frame 5 is of a U-shaped structure and is fixed on the support bottom plate. A placing groove 6 with a circular arc-shaped longitudinal section is arranged under the top wall of the support frame 5. The support shaft 4 is placed on the placing groove 6. One end of the support frame 5 is fixed with a first pushing cylinder 7. A bottom block 8 is fixed at one end of the first pushing cylinder 7. A driving motor 9 is fixed on the bottom block 8. A connecting end shaft 18 is arranged on the driving motor 9. A clamping block 13 is fixed at one end of the connecting end shaft 18. A clamping groove 14 matching the clamping block 13 is arranged on the support shaft 4 near the driving motor 9. The longitudinal sections of the clamping block 13 and the clamping groove 14 are both polygonal. The first pushing cylinder 7 drives the bottom block 8, the driving motor 9 and the clamping block 13 to move as a whole, and the clamping block 13 is clamped into the clamping groove 14. The driving motor 9 drives the connecting end shaft 18 to rotate, thereby driving the support shaft 4 to rotate. The support shaft 4 drives the connecting rod 3 and the flipping frame 2 to rotate, so as to flip the excavator connecting platform.

[0021] As Figure 2 、 3As shown, a limit frame 11 is pressed onto the support shaft 4, and the limit frame 11 is an L-shaped structure. The top wall of the limit frame 11 is tangent to the support shaft 4, and a pushing cylinder 2 10 is fixed at the connection between the outer wall of the vertical end of the limit frame 11 and the side wall of the support frame 5. The pushing cylinder 2 10 drives the limit frame 11 to move onto the support shaft 4, and limits the vertical position of the support shaft 4. A limiting end plate 12 is fixed on the side of the outer wall of the top of the limit frame 11 away from the drive motor 9. The limiting end plate 12 is an L-shaped structure, and the outer wall of the vertical end of the limiting end plate 12 is close to one end of the support shaft 4, and limits the support shaft 4 laterally.

[0022] A mounting block 15 is fixed on the inner side wall around the flip frame 2, a hydraulic push rod 16 is fixed on the mounting block 15, and a fixing block 17 is fixedly connected to the hydraulic push rod 16. The hydraulic push rod 16 drives the fixing block 17 to clamp and fix the excavator platform.

[0023] When in use, the excavator platform is placed on the supporting base plate 1 and located in the flip frame 2. The hydraulic push rod 16 drives the fixed block 17 to clamp the excavator platform, pushes the cylinder 2 10 to drive the bottom block 8 and the driving motor 9 to move, and the blocking block 13 is clamped into the card slot 14, and pushes the cylinder 1 7 to drive the limit frame 11 close to the support shaft 4. The limit frame 11 drives the limit end plate 12 to move, and limits the support shaft 4 up, down, left and right. At this time, the limit frame 11 and the driving motor 9 located at the adjacent vertical edges of the flip frame 2 are in the initial position, and the limit frame 11 and the bottom block 8 are away from the support shaft 4, providing enough space for the rotation of the support shaft 4; the driving motor 9 drives the support shaft 4 to rotate, and the support shaft 4 drives the connecting rod 3 and the flip frame 2 to rotate, thereby flipping the excavator platform. The flipping direction can be switched arbitrarily, so that the flipping can be carried out in two planes to meet more usage requirements.

[0024] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
