[0051] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0052] like Figure 1-Figure 6 As shown, the present invention provides a flipping device, including a base body 1, a flip frame 2 and two driving mechanisms 3. The flip frame 2 includes a side support sheet 21, a side support sheet 22, a transfer sheet 23 and a support shaft 24. The side support sheet 21 is connected to one end of the side support sheet 22 in the first direction. Two transfer sheets 23 are provided. The two transfer sheets 23 are respectively connected to the two ends of the side support sheet 22 in the second direction. The side support sheet 21 is perpendicular to the side support sheet 22 and extends in an arc shape in the second direction. The two ends are respectively connected to the two transfer sheets 23. The first direction is perpendicular to the second direction. Each transfer sheet 23 is fixedly connected to a support shaft 24. The transfer sheet 23 is supported by the support The rotating shaft 24 is rotatably connected to the base body 1. When the three-dimensional net 100 is carried on the flip frame 2, one side surface is against the side support sheet 21, one end surface in the width direction is against the side support sheet 22, and the two end surfaces in the length direction are located between the two adapter sheets 23. The output ends of the two driving mechanisms 3 are connected to the two supporting rotating shafts 24 one by one. The two driving mechanisms 3 can drive the flip frame 2 to switch between the receiving state and the lying state. In the receiving state, the side support sheet 22 is located at the bottom of the flip frame 2, and in the lying state, the side support sheet 21 is located at the bottom of the flip frame 2.

[0053] In the present invention, two driving mechanisms 3 drive the flip frame 2 to switch between the receiving state and the laying down state, so that the force on the flip frame 2 is more balanced and the flipping is more stable. The side support sheet 21 and the side support sheet 22 on the flip frame 2 cooperate with each other. The side support sheet 21 can be attached to one side of the three-dimensional net 100, and the side support sheet 22 can be attached to one end face of the three-dimensional net 100 in the width direction, so that in the receiving state, the flip frame 2 can smoothly and conveniently receive the vertical three-dimensional net 100 processed by the three-dimensional net production line 30, and after receiving the three-dimensional net 100, the flip frame 2 can be driven by the driving mechanism 3 to switch to the laying down state efficiently and quickly, omitting manual participation, and realizing the laying down of the three-dimensional net 100. During the laying down process, the side support sheet 21 is attached to one side of the three-dimensional net 100, and the side support sheet 22 is attached to one end face of the three-dimensional net 100, so that the three-dimensional net 100 is subjected to uniform force, thereby avoiding deformation and damage of the three-dimensional net 100, ensuring the quality of the three-dimensional net 100, and being safer and more reliable.

[0054] In this embodiment, the first direction is the width direction of the side support sheet 22, and the second direction is the length direction of the side support sheet 22. Figure 4 As shown, the X direction is the length direction of the three-dimensional net 100, the Y direction is the thickness direction of the three-dimensional net 100, and the Z direction is the width direction of the three-dimensional net 100. The two end surfaces in the thickness direction of the three-dimensional net 100 are side surfaces, the concave side surfaces are inner curved surfaces, and the convex side surfaces are outer curved surfaces.

[0055] Specifically, the base body 1 includes a bottom support 11 and a side support 12 connected to each other, two side support 12 are provided, in the second direction, the two side support 12 are provided at both ends of the bottom support 11, the flip frame 2 is provided between the two side support 12, and the two support shafts 24 are rotatably provided on the two side support 12 in a one-to-one correspondence. The above arrangement makes the flip frame 2 more balanced and reliable during the rotation process.

[0056] More specifically, the two side support seats 12 are each provided with a bearing support 13, a bearing is fixedly installed in the bearing support 13, a support shaft 24 is fixedly passed through the inner ring of the bearing, and the support shaft 24 is rotatably provided on the side support seat 12 through the bearing support 13 and the bearing. The above arrangement makes the rotation of the flip frame 2 smoother.

[0057] More specifically, the cross-sectional area of ​​the side support 12 gradually decreases in the direction away from the bottom support 11, and the bearing support 13 is fixed to one end of the side support 12 away from the bottom support 11. The above arrangement makes the support of the side support 12 to the bearing support 13 more stable and reliable, and not easy to overturn.

[0058] In this embodiment, the side support sheet 21, the side support sheet 22, the adapter sheet 23, the bottom support bracket 11 and the side support bracket 12 are all assembled by hollow beams and columns, which are lighter in weight while ensuring structural strength. When the seat body 1 is placed on the ground, the bottom support bracket 11 is in contact with the ground, and the bearing bracket 13 is arranged on the top of the side support bracket 12. Figure 2 As shown, in the receiving state, the side support sheet 22 is located at the bottom of the flip frame 2, as shown in FIG. Figure 3 As shown, in the laid-down state, the side support sheet 21 is located at the bottom of the turning frame 2 .

[0059] Specifically, in the second direction, the seat body 1 is located between the two driving mechanisms 3. The above arrangement avoids interference between the flip frame 2 and the two driving mechanisms 3 during the rotation process.

[0060] More specifically, the side support sheet 21 is configured to be close to the inner curved surface of the three-dimensional net 100 , so that the force on the three-dimensional net 100 is more dispersed during the turning process of the turning frame 2 .

[0061] More specifically, the size of the adapter sheet 23 in the first direction gradually decreases in the direction away from the temple sheet 22. The above arrangement enables the two end surfaces of the three-dimensional net 100 in the longitudinal direction to be exposed when the three-dimensional net 100 is carried on the turning frame 2, making it easier to take, place and transport.

[0062] In this embodiment, the adapter plate 23 is in the shape of a right triangle, and two right-angled sides are respectively connected to the side support plate 21 and the edge support plate 22 .

[0063] In other embodiments, the adapter sheet 23 may also be in the shape of a right-angle trapezoid. In other embodiments, the side support sheet 21 may also be configured to be close to the outer curved surface of the three-dimensional net 100 .

[0064] Specifically, the driving mechanism 3 includes a fixed support 31, an electric push rod 32 and a swing arm 33. The fixed support 31 is fixedly arranged relative to the base 1, the electric push rod 32 is rotatably mounted on the fixed support 31, one end of the swing arm 33 is rotatably connected to the output end of the electric push rod 32, and the other end is fixedly connected to the support shaft 24. The above arrangement enables the driving mechanism 3 to drive the flip frame 2 to rotate in a balanced and reliable manner.

[0065] More specifically, the cross-sectional area of ​​the swing arm 33 gradually increases from the end connected to the electric push rod 32 to the end connected to the support shaft 24. The above arrangement increases the structural strength of the connection between the swing arm 33 and the support shaft 24, and improves the reliability and safety of the swing arm 33 during operation.

[0066] In this embodiment, the seat body 1 is arranged between two fixed supports 31. When the flip frame 2 is in a receiving state, in the first direction, the fixed support 31 and the side support sheet 21 are located on the same side of the supporting shaft 24, thereby avoiding interference between the driving mechanism 3 and other devices when taking and placing the three-dimensional net 100.

[0067] In other embodiments, the electric push rod 32 in the driving mechanism 3 may also be replaced by a pneumatic cylinder, an electric cylinder, a hydraulic cylinder, etc.

The side support sheet 21 and the side support sheet 22 on the flip frame 2 cooperate with each other. The side support sheet 21 can be attached to one side of the three-dimensional net 100, and the side support sheet 22 can be attached to one end face in the width direction of the three-dimensional net 100, so that in the receiving state, the flip frame 2 can smoothly and conveniently receive the vertical mesh obtained by the three-dimensional net production line 30. The three-dimensional net 100 is in a vertical position, and after receiving the three-dimensional net 100, the flip frame 2 can be switched to a laid-down state efficiently and quickly under the drive of the driving mechanism 3, thereby omitting manual intervention and realizing the laying down of the three-dimensional net 100. During the laying down process, the side support sheet 21 is attached to a side surface of the three-dimensional net 100, and the side support sheet 22 is attached to an end surface of the three-dimensional net 100, so that the three-dimensional net 100 is evenly stressed, thus avoiding deformation and damage of the three-dimensional net 100, ensuring the quality of the three-dimensional net 100, and making it safer and more reliable.

The curved steel bars are welded in the single-piece mesh welding mechanism to obtain the single-piece mesh 101.

[0071] More specifically, the three-dimensional mesh production line 30 includes a three-dimensional mesh welding mold, a welding adjustment track and a welding manipulator. There are at least two three-dimensional mesh welding molds, both of which are arranged downstream of the single-piece mesh welding mechanism, and are used to position and fix multiple single-piece meshes 101 and stirrups 102 assembled on the multiple single-piece meshes 101, wherein the stirrups 102 are assembled on the multiple single-piece meshes 101 manually or by a stirrup assembly device. The hoisting and transporting device 20 is arranged between the single-piece mesh welding mechanism and the three-dimensional mesh welding mold. The hoisting and transporting device 20 is used to grab the single-piece mesh 101 processed on the single-piece mesh welding mechanism and stack them in sequence on at least two three-dimensional mesh welding molds. There are at least two welding manipulators, which are respectively slidably arranged on the welding adjustment track.
