[0032] Reference Figure 1, the feeding component 1 conveys the steel bars to the long bar conveying component 3 and the short bar conveying component 2.

The long bar conveying component 3 has different conveying schemes according to the design situation: if the long bar needs to be bent, the long bar conveying component 3 conveys the long bar to the bending component, the moving component 4 drives the tray 5 to move toward the bending component, and the long bar handling component 7 carries the bent long bar to the tray 5; if the long bar does not need to be bent, the long bar conveying component 3 still conveys the long bar to the bending component, the bending component stops operating, and the long bar handling component 7 directly carries the long bar to the tray 5.

[0033] Reference Figure 1 It is easy to understand that in order to further improve the production efficiency of the prestressed positioning mesh, the long rib conveying assembly 3, the short rib conveying assembly 2, the moving assembly 4 and the tray 5 can be arranged on the same side of the feeding assembly 1, and another set of long rib conveying assembly 3, short rib conveying assembly 2, the moving assembly 4 and the tray 5 can be arranged on the other side of the feeding assembly 1. During the welding and fixing process of the long ribs and the short ribs in the tray 5 on one side, the long ribs and the short ribs can be arranged in the tray 5 on the other side, so as to improve the production efficiency of the prestressed positioning mesh.

The rollers 32 are arranged on the transmission shaft 34. The bottom frame 33 is arranged in the frame 8. The frame 8 is specifically formed by a plurality of supporting columns connected and fixed to each other. A first driving motor 35 is arranged in the bottom frame 33. The first driving motor 35 is connected to the transmission shaft 34 through a chain. The operation of the first driving motor 35 drives the plurality of transmission shafts 34 to rotate synchronously, and further drives the rollers 32 to rotate. After the long rib falls on the rollers 32, it can move in a direction perpendicular to the conveying direction of the conveyor belt 31 under the drive of the rollers 32.

[0035] Reference Figure 2 and Figure 3The bottom frame 33 includes a top plate 332 and a support frame 331. A plurality of mounting seats 37 are fixed on the top plate 332. The transmission shaft 34 is arranged in the mounting seats 37. The first driving motor 35 is fixed on the bottom surface of the top plate 332. A vertically arranged slide rail 335 is fixed on the side wall of the support frame 331. A sliding block 333 is arranged on the slide rail 335.

The piston rod of the lifting cylinder 36 is fixedly connected to the top plate 332. In the initial state, the piston rod of the lifting cylinder 36 is in a retracted state. The top end of the roller 32 is flush with the top surface of the conveyor belt 31 or slightly lower than the top surface of the conveyor belt 31. The conveyor belt 31 can transport the long tendons. When the long rib moves to above the roller 32, the piston rod of the lifting cylinder 36 extends to push the top plate 332 up. The roller 32 rises as the long rib contacts the roller 32 and rises under the support of the roller 32. At this time, the long rib is separated from the conveyor belt 31 and moves in a direction perpendicular to the conveying direction of the conveyor belt 31 driven by the roller 32.

A second driving motor 13 is fixed on the fixing frame 9, and the second driving motor 13 is connected to the plurality of connecting shafts 11 through a chain sprocket, and can drive the plurality of connecting shafts 11 to rotate synchronously. The setting of the fixing frame 9 is used to transfer the long steel bars. At the same time, because the long steel bars are long and heavy, part of the long steel bars are supported by the fixing frame 9 and the transmission wheel 12 to prevent excessive load on the conveyor belt 31 and the roller 32.

[0038] Reference Figure 4The short rib transport assembly 6 includes a first fixed rod 61, a first mounting rod 62 and a first clamping claw 63.

A connecting frame 65 is fixed to the first moving plate 64. A first lifting cylinder 66 is installed at the bottom end of the connecting frame 65. The first mounting rod 62 is arranged at the bottom end of the first lifting cylinder 66. The first clamping claw 63 is arranged at the bottom end of the first mounting rod 62. A plurality of first clamping claws 63 are provided, and the plurality of first clamping claws 63 are arranged at intervals. The number of the first clamps 63 corresponds to the number of short ribs that need to be placed on the pallet 5, so that the short ribs in one pallet 5 can be arranged in one transport, thereby improving the processing efficiency of the prestressed positioning mesh.

[0039] Reference Figure 5 and Figure 6 The long rib handling assembly 7 includes a second fixed rod 71, a second mounting rod 72, a second clamping jaw 73, a third clamping jaw 74 and a fourth clamping jaw 75. The second fixed rod 71 is the same as the first fixed rod 61 and can be fixed on the top of a column or the like, and is located above the bending assembly and the moving assembly 4.

The second clamp 73, the third clamp 74 and the fourth clamp 75 are arranged in the same direction so as to be able to grasp the long reinforcing bar. Due to the different specifications of the prestressed positioning mesh, the long reinforcing bar may be bent or not bent. Therefore, the second clamp 73 and the third clamp 74 are in a straight line, and there is an intersection between the second clamp 73 and the fourth clamp 75. In other words, the second clamp 73 and the third clamp 74 are used to grasp the long reinforcing bar without bending, the second clamp 73 and the fourth clamp 75 grasp the bent reinforcing bar, the second clamp 73 grasps the unbent part of the long reinforcing bar, and the fourth clamp 75 is used to grasp the bent part of the long reinforcing bar.

At this time, the slider 15 drives the second support plates 53 to move away from each other, so as to increase the distance between the second support plates 53, thereby adapting to the production of prestressed positioning meshes of different specifications.

[0042] Reference Figure 7 A fixing plate 17 is fixed on the top surface of the mounting frame 51, and a pressure rod 19 is hinged on the fixing plate 17.

A bolt is fixed on the piston rod of the second electric push rod 18, and the bolt passes through the sliding hole and the guide hole. In the initial state, the piston rod of the second electric push rod 18 is extended, and the bolt slides at the top of the sliding hole and the guide hole. The free end of the pressure rod 19 is tilted upward to facilitate the short rib to be placed in the first slot 54. After the short rib is placed in the first slot 54, the piston rod of the second electric push rod 18 is retracted, and the bolt slides from the top of the guide hole to the bottom, and slides from the top of the sliding hole to the bottom, while driving the free end of the pressure rod 19 to swing downward, and the free end of the pressure rod 19 presses the short rib in the first slot 54 to improve the stability of the short rib in the first slot 54.

In the initial state, the piston rod of the third electric push rod 20 is in an extended state, and one end of the swing rod 21 with the locking rod 22 swings away from the second slot 55, so that the long rib is placed in the second slot 55. After the long rib is placed in the second slot 55, the piston rod of the third electric push rod 20 retracts, so that the locking rod 22 moves toward the second slot 55, thereby pressing the long rib in the second slot 55, and improving the stability of the long rib in the second slot 55. By fixing the long rib and the short rib, the stability of the subsequent welding of the long rib and the short rib is improved, and the welding quality of the prestressed positioning mesh is improved.
