[0002] Steel strands are widely used in the construction of highway bridge prestressed projects, which can enhance the load-bearing strength of reinforced concrete. During the prestressed construction process, multiple steel strands of a fixed length need to be inserted into the process holes of the beam body. Steel strands are made of high-carbon steel wires, with high strength and hardness. Manual operation has a very high labor intensity, extremely low efficiency, and is very likely to cause harm to the human body if operated improperly.

[0003] Steel strand threading is a basic operation in the construction of highway bridge prestressed projects. In particular, the whole-bundle threading of multiple steel strands is the quality guarantee of the beam body prestressed construction and also the development direction of this technology. However, at present, steel strand threading equipment can often only perform single-strand operations, with low efficiency and unable to avoid the occurrence of the phenomenon of mutual cross-winding of multiple steel strands after being inserted into the beam body. For the above reasons, the development of the whole-bundle steel strand bundling process has become an important technical means. When threading the whole bundle of steel strands, it is required to tie the whole bundle of steel strands tightly with 0.8mm tying wire every 1 meter as required.

For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0034] In one embodiment of the present invention, as Figure 1 shown, an automatic tying device for steel strand binding wire includes a tying assembly 1, a driving assembly 2, a binding wire clamping assembly 3, and a binding wire tightening assembly 4;

[0035] Among them, the tying assembly 1 is used to tie the binding wire around the steel strand, the driving assembly 2 is used to drive the tying assembly 1 to complete the automatic tying of the steel strand, the binding wire clamping assembly 3 is used to clamp one end of the binding wire so that the binding wire can be smoothly tied to the steel strand, and the binding wire tightening assembly 4 is used to tighten the binding wire on the steel strand.

[0036] As Figure 2As shown, the bundling assembly 1 includes a first support frame 11, a second support frame 12 fixed above the first support frame 11, and a steel strand inlet formed in the first support frame 11. A rotating ring 13 is coaxially rotatably connected to one side of the steel strand inlet. A plurality of driving wheels 14 for driving the rotating ring 13 to rotate around the center of the steel strand inlet are provided on the periphery of the rotating ring 13. A wire tying roller 16 is connected to the rotating ring 13;

[0037] Specifically, the rotating ring 13 is specifically an annular structure. A through hole is formed in the rotating ring 13. The through hole is coaxially arranged with the steel strand inlet. When the steel strand is being bundled, it needs to pass through the through hole in the rotating ring 13 and the steel strand inlet in sequence. At the same time, the rotating ring 13 can rotate along the center of the steel strand inlet. The size of the rotating ring corresponds to the steel strand inlet, so that the rotating ring 13 will not generate lateral, longitudinal, and vertical displacements during rotation. A clamping block is provided at the rear side of the rotating ring 13, and an annular chute corresponding to the clamping block is provided on the periphery of the steel strand inlet. While the rotating ring 13 rotates, the corresponding clamping block also moves annularly in the annular chute, so as to limit the position of the rotating ring 13 and prevent it from accidentally falling;

[0038] At the same time, the driving wheels 14 are arranged on the periphery of the rotating ring 13. The driving wheels 14 can be structures such as gears and discs. Through the frictional force or meshing force between the driving wheels 14 and the rotating ring 13, the driving wheels 14 can drive the rotating ring 13 to rotate. Correspondingly, a wire tying roller 16 is provided on the rotating ring 13, and wire ties are wound on the wire tying roller 16. Therefore, in the actual bundling process, only one end of the wire tie needs to be pulled out from the wire tying roller 16, and the rotating ring 13 is used to drive the wire tying roller 16 to rotate, and the wire tie can be bundled around the steel strand.

[0039] As Figure 3 shown, the driving assembly 2 is installed on the first support frame 11. The driving assembly 2 is used to drive the driving wheels 14 to rotate. The driving assembly 2 includes a first stepping motor 21 installed on one side of the first support frame 11 and a driving shaft 25 connected to the output end of the first stepping motor 21. The driving shaft 25 is connected to a plurality of the driving wheels 14 through a chain transmission assembly;

[0040] Specifically, the number of chain drive assemblies is set corresponding to the number of drive wheels 14. Each chain drive assembly includes a first sprocket, a second sprocket, and a drive chain connected between the first sprocket and the second sprocket. The first sprocket is fixed on the drive shaft 25, and the second sprocket is fixedly connected coaxially with the drive wheel 14. Therefore, the first stepping motor 21 can drive the drive shaft 25 to rotate, and then further drive the drive wheel 14 to rotate through the transmission of the chain drive assembly. The rotation of the drive wheel 14 drives the rotation ring 13 to rotate, so that the binding wire is bundled around the steel strand.

[0041] It is worth noting that the first stepping motor 21 can be used to control the number of rotation turns of the rotation ring 13, and thus can control the length and density of the binding wire wound around the steel strand. At the same time, the first stepping motor 21 can also control the stop position of the binding wire on the binding wire roller 16, so that the binding wire tightening assembly can tighten the two ends of the binding wire on the steel strand.

[0042] As Figure 4 shown, the binding wire clamping assembly 3 is installed on one side of the first support frame 11. The binding wire clamping assembly 3 includes a first driving cylinder 33 installed on one side of the first support frame 11, a first clamping cylinder 34 connected to the output end of the first driving cylinder 33, and two relatively arranged first clamping plates 35 connected to the output end of the first clamping cylinder 34. The two first clamping plates 35 are arranged on one side of the binding wire roller 16.

[0043] Specifically, the binding wire clamping assembly 3 is used to clamp the initial end of the binding wire. After the steel strand passes through the steel strand inlet, at this time, the first driving cylinder 33 is controlled to drive the first clamping cylinder 34 and the first clamping plates 35 to move towards the binding wire roller 16. Then, the first clamping cylinder 34 is controlled to make the two first clamping plates 35 clamp and fix the initial end of the binding wire. Then, the first driving cylinder 33 is controlled to reset, pulling the binding wire out of the binding wire roller 16. Then, the rotation ring 13 can be used to drive the binding wire roller 16 to rotate, so that the binding wire pulled out by the first clamping plate 35 can be wound around the steel strand. During this process, the first clamping plate 35 always clamps and fixes the initial end of the binding wire to prevent the binding wire from loosening during bundling.

[0044] As Figure 5As shown, the wire tightening assembly 4 is installed on the second support frame 12. The wire tightening assembly 4 includes a second driving cylinder 41 installed on the second support frame 12, a driving plate 42 connected to the output end of the second driving cylinder 41, and a second stepping motor 43 fixed on the driving plate 42. The output end of the second stepping motor 43 is connected to a second clamping cylinder 45 through a rotary joint 44. The output end of the second clamping cylinder 45 is provided with two oppositely arranged second clamping plates 47. Oppositely arranged cutting blades 48 are provided on the two second clamping plates 47. The two second clamping plates 47 are arranged above the wire roller 16;

[0045] Specifically, after the steel strand is bundled, the initial end of the wire is clamped and fixed by the first clamping plate 35, while the other end of the wire is still wound around the wire roller 16. In order not to affect the subsequent bundling of the steel strand, it is necessary to cut the wire. Therefore, after the steel strand is bundled, the second driving cylinder 41 drives the second stepping motor 43, the second clamping cylinder 45, and the second clamping plate 47 to move towards the direction of the rotating ring 13, and the second clamping cylinder 45 controls the second clamping plate 47 to clamp and fix the remaining wire after winding and the wire clamped by the first clamping plate 35. During this process, the stop position of the wire roller 16 can be controlled by the first stepping motor 21. Therefore, after bundling, the wire on the wire roller after bundling can be controlled to stay at a position close to the wire clamped by the first clamping plate 35. Therefore, the second clamping cylinder 45 drives the second clamping plate 47 to clamp and fix the two ends of the wire, and then controls the first clamping cylinder 34 to reset to release the wire by the first clamping plate 35. During the clamping process, the remaining wire is cut by the cutting blade 48 on the second clamping plate 47 to separate it from the wire roller 16. Therefore, both ends of the wire are clamped between the second clamping plates 47 at this time. Then, the second stepping motor 43 drives the second clamping plate 47 to rotate to tighten and fix the wire on the steel strand.

[0046] In this embodiment, there are two driving wheels 14, and an auxiliary wheel 15 is provided on the periphery of the rotating ring 13. The two driving wheels 14 and the auxiliary wheel 15 are arranged at equal angles on the periphery of the rotating ring 13. The auxiliary wheel 15 is rotatably connected to the first support frame 11;

[0047] Specifically, the two driving wheels 14 and one auxiliary wheel 15 form a triangular structure, and the position of the rotating ring 13 can be limited by the two driving wheels 14 and one auxiliary wheel 15, which can not only reduce the number of driving wheels 14 but also ensure the normal operation of the rotating ring 13.

[0048] As Figure 6As shown, in this embodiment, a binding wire roller mounting seat 17 is fixedly connected to the rotating ring 13. The binding wire roller 16 is rotatably connected to the binding wire roller mounting seat 17. A binding wire guiding tube 18 is mounted on the binding wire roller mounting seat 17, and one end of the binding wire guiding tube 18 is bent towards the center of the rotating ring 13.

[0049] Specifically, by providing the binding wire guiding tube 18, the output of the binding wire can be restricted, preventing the binding wire from getting knotted and entangled, which may affect the process of steel strand bundling.

[0050] In this embodiment, a number of reinforcing rib plates 19 are fixed to one side of the second support frame 12.

[0051] Specifically, the stability of the second support frame 12 can be enhanced by the reinforcing rib plates 19, thereby improving the load-bearing capacity of the second support frame 12.

[0052] In this embodiment, a proximity sensor 28 is installed on one side of the steel strand inlet.

[0053] Specifically, the proximity sensor 28 can be used to sense the arrival of the steel strand. The proximity sensor 28, the first stepping motor 21, the first driving cylinder 33, the first clamping cylinder 34, the second driving cylinder 41, the second stepping motor 43, and the second clamping cylinder 45 cooperate with the PLC control to complete the automatic bundling of the steel strand.

[0054] In this embodiment, a fixed cylinder 22 is fixed to one side of the first stepping motor 21. A first fixed disk 23 is fixed to one side of the fixed cylinder 22. A second fixed disk 26 is fixed to one side of the first support frame 11. A number of fixed rods 24 are fixed between the first fixed disk 23 and the second fixed disk 26. The drive shaft 25 sequentially passes through the fixed cylinder 22, the first fixed disk 23, and the second fixed disk 26 in a movable manner, and one end of the drive shaft 25 is rotatably connected to one side of the first support frame 11.

[0055] Specifically, the first stepping motor 21 can be fixed to one side of the first support frame 11 through the fixed cylinder 22, the first fixed disk 23, and the second fixed disk 26 to support and stabilize the first stepping motor 21.

[0056] In this embodiment, a first mounting seat 31 is fixed to one side of the first driving cylinder 33. A second mounting seat 32 is fixed to one side of the first mounting seat 31. The second mounting seat 32 is fixed to one side of the first support frame 11.

[0057] Specifically, the first driving cylinder 33 is fixed to the first support frame 11 through the first mounting seat 31 and the second mounting seat 32 to support and stabilize the first driving cylinder 33.

[0058] In this embodiment, a number of anti-slip grooves are provided on the opposite sides of the two first clamping plates 35 and the two second clamping plates 47;

[0059] Specifically, by providing a number of anti-slip grooves, the friction between the first clamping plate 35, the second clamping plate 47 and the binding wire can be increased, and the situation of accidental loosening or dropping of the binding wire can be avoided.

[0060] In this embodiment, a protective plate mounting bracket 49 with a right-angled structure is fixed on one side of the driving plate 42. A protective plate 46 is fixedly connected below the protective plate mounting bracket 49. The protective plate 46 is arranged on one side of the second clamping cylinder 45 and the second clamping plate 47;

[0061] Specifically, by providing the protective plate mounting bracket 49, the stability of the protective plate 46 can be ensured, and the anti-slip plate 46 can play a protective role to protect the second clamping cylinder 45 and the second clamping plate 47.

[0062] In this embodiment, the opposite sides of the cutting blades 48 extend inward until they exceed the opposite sides of the two second clamping plates 47;

[0063] Specifically, by protruding the cutting sides of the cutting blades 48, that is, during the process of the two second clamping plates 47 clamping the binding wire, the binding wire can be smoothly cut off.

[0064] The working principle of the present invention is as follows: When the steel strand passes through the steel strand inlet, at this time, the first driving cylinder 33 is controlled to drive the first clamping cylinder 34 and the first clamping plate 35 to move towards the binding wire roller 16. Then, the first clamping cylinder 34 is controlled to make the two first clamping plates 35 clamp and fix the initial end of the binding wire. Then, the first driving cylinder 33 is controlled to reset, and the binding wire is pulled out from the binding wire roller 16. Then, the binding wire roller 16 is driven to rotate by the rotating ring 13, so that the binding wire pulled out by the first clamping plate 35 is wound around the periphery of the steel strand. When the steel strand bundling is completed, the second driving cylinder 41 is controlled to drive the second stepping motor 43, the second clamping cylinder 45, and the second clamping plate 47 to move towards the rotating ring 13, and the second clamping cylinder 45 is controlled to make the second clamping plate 47 clamp and fix the remaining binding wire after winding and the binding wire clamped by the first clamping plate 35. Then, the first clamping cylinder 34 is controlled to reset to release the binding wire by the first clamping plate 35. During the clamping process, the remaining binding wire is cut off by the cutting blades 48 on the second clamping plate 47 to be separated from the binding wire roller 16. Then, the second stepping motor 43 drives the second clamping plate 47 to rotate to tighten and fix the binding wire on the steel strand. When the binding wire is tightened, the equipment is controlled to reset to start the next bundling.

[0065] In summary, for the automatic tying device for steel strand tying wires in the above embodiments of the present invention, the steel strand is passed through the rotating ring 13, and one end of the tying wire is clamped by the tying wire clamping assembly 3. The rotating ring 13 is driven to rotate by the driving assembly 2, thereby driving the tying wire to wind around the periphery of the steel strand. Finally, the tying wire is cut off by the tying wire tightening assembly 4, and both ends of the tying wire are clamped to drive the tying wire to be tightened to complete the automatic tying of the steel strand. The present invention can realize the automatic tying of the steel strand, greatly improving the efficiency of steel strand tying, and at the same time avoiding the situation that the staff is injured by the tying wire.

[0066] The foregoing is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
