Description

Technical Field

[0001] This invention relates to the field of large wire drawing machine technology, and in particular to a wire traction device for a large wire drawing machine. Background Technology

[0002] In my country's wire and cable industry, large drawing machines are used to draw wires from rods (which are thicker wires) into thinner wires. Large drawing machines are commonly used equipment. In current operations, one end of the coiled rod is pulled upwards to a platform to straighten the rod and pull it down before it enters the large drawing machine for thinning.

[0003] Before the pole is pulled over the platform, workers need to send one end of the pole onto the platform and pass it through tensioning wheels and other mechanisms on the platform to straighten it and convey it downwards. Finally, it is fed into the large pulling machine by conveying rollers at the same height as the feed inlet of the large pulling machine.

[0004] Since each time a single bundle of poles is used up, it is necessary to manually go up to the platform to pull it to supply the wire drawing material for the subsequent large drawing machine, this operation is laborious and inefficient, and there is also an accident risk for workers to work at height. Therefore, how to automatically pull the wire on the platform when the large drawing machine is loading is a technical problem that needs to be solved. Summary of the Invention

[0005] In view of this, it is necessary to provide a wire traction device for a large wire drawing machine to solve the technical problem of how to automatically traction the wire on the high platform when loading the large wire drawing machine in the prior art.

[0006] To achieve the above-mentioned technical objectives, the present invention provides a wire traction device for a large drawing machine, comprising:

[0007] high platform;

[0008] A clamping wheel assembly includes a telescopic frame, a self-driving wheel, and a driven wheel. The self-driving wheel and the driven wheel are both disposed on the telescopic frame. The self-driving wheel and the driven wheel are positioned opposite each other and form a first gap. The telescopic frame is used to move the driven wheel closer to or away from the self-driving wheel. When the driven wheel is close to the self-driving wheel, the wire can be clamped and conveyed upward.

[0009] A lifting mechanism is provided on the high platform to drive the clamping wheel assembly to move up and down;

[0010] The tensioning assembly, located on a high platform, is used to connect with the wire conveyed by the clamping wheel assembly and guide the wire to hang downwards.

[0011] Furthermore, it also includes a connecting component, which includes a receiving tube, a conveying wheel assembly, and a guide tube. The receiving tube is located directly below the drop point of the wire guided by the tensioning component. The conveying wheel assembly is located at the discharge end of the receiving tube. The guide tube is located adjacent to the conveying wheel assembly and is used to connect with the conveying wheel assembly to convey the wire.

[0012] Furthermore, the tensioning assembly includes a mounting frame, a second telescopic member, an auxiliary wheel, a steering wheel, and a curved plate. The mounting frame is disposed on the elevated platform, the second telescopic member is disposed on the mounting frame, the auxiliary wheel is rotatably connected to the telescopic end of the second telescopic member, and the auxiliary wheel is positioned opposite the steering wheel, and the auxiliary wheel and the steering wheel are positioned opposite each other to form a second gap, the second gap being directly above the first gap. The second telescopic member is used to drive the auxiliary wheel closer to or away from the steering wheel, and the curved plate is connected to the elevated platform through a bracket and is located above the steering wheel, used to guide the wire to hang downwards.

[0013] Furthermore, the curved plate bends upward in an arc shape from the second gap, passing over the steering wheel, and then bends downward to the other side of the steering wheel.

[0014] Furthermore, the telescopic frame includes a frame and a first telescopic member. The frame is connected to the lifting end of the lifting mechanism, the self-driving wheel is rotatably connected to the frame, the first telescopic member is disposed on the frame, and the driven wheel is rotatably connected to the telescopic end of the first telescopic member.

[0015] Furthermore, the receiving tube includes a first flared opening and a bent tube. The first flared opening is located at the top of the bent tube and faces upward, while the other end of the bent tube is bent to a horizontal position.

[0016] Furthermore, the guide tube includes a second flared opening and a tube body, with the large circular end of the second flared opening facing the bottom end of the bent tube, and the other end of the second flared opening connected to the tube body.

[0017] Furthermore, the connecting assembly also includes a base frame, on which the receiving pipe, the conveying wheel assembly, and the guide pipe are installed sequentially from left to right.

[0018] Furthermore, the conveyor wheel assembly includes a pair of rollers distributed vertically.

[0019] Furthermore, annular grooves are provided on the outer sides of the self-driving wheel, driven wheel, auxiliary wheel, and steering wheel.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The operator only needs to load one end of the pole onto the clamping wheel assembly on the ground. The lifting mechanism, clamping wheel assembly and tensioning assembly will then work together to automatically pull and lower the pole, reducing the number of times workers need to climb to heights and improving the safety and efficiency of this process.

[0022] 2. The connecting component eliminates the need to pull the drooping poles, automatically connecting them and conveying them to the feed inlet of the large pulling machine, thus improving the feeding efficiency. Attached Figure Description

Detailed Implementation

[0028] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0029] like Figure 1-4As shown, the present invention provides a wire traction device for a large wire drawing machine, including a platform 1, a lifting mechanism 2, a clamping wheel assembly 3, and a tensioning assembly 4; the lifting mechanism 2 is disposed on the platform 1 and is used to drive the clamping wheel assembly 3 to lift and lower; the clamping wheel assembly 3 includes a telescopic frame, a self-driving wheel 34, and a driven wheel 33, both the self-driving wheel 34 and the driven wheel 33 are disposed on the telescopic frame, the telescopic frame is connected to the lifting end of the lifting mechanism 2, and the self-driving wheel 34 and the driven wheel 33 are positioned opposite each other to form a tensioning assembly 4. The first gap is used to clamp the rod 6 that needs to be lifted, and the telescopic frame is used to move the driven wheel 33 closer to or away from the self-driving wheel 34. When the driven wheel 33 is close to the self-driving wheel 34, the wire can be clamped and conveyed upward. When the wire is a thicker rod 6, the rod 6 is clamped and conveyed upward. The tensioning component 4 is set on the high platform to connect with the wire conveyed by the clamping wheel component 3 and guide the wire to hang downward. It has the functions of tensioning the rod 6 and reversing the downward conveying.

[0030] In use, the lifting mechanism 2 lowers the clamping wheel assembly 3 to a height that a person can reach on the ground, places one end of the rod 6 into the first gap, and clamps the rod 6 by the driven wheel 33 and the self-driving wheel 34. Then, the lifting mechanism 2 lifts the rod 6, pulling it upward. When it rises to the height of the platform 1, it connects to the tensioning assembly 4. Through the rotation driven by the self-driving wheel 34, the rod 6 can be transported upward into the tensioning assembly 4, thus automatically connecting to the tensioning assembly 4 to tension the rod 6 and reverse its direction to be transported downward.

[0031] Understandably, once pole 6 is transported down from platform 1, manual operations can continue on the ground. The entire operation does not require climbing, reducing safety risks in this process. Furthermore, the end of pole 6 is clamped directly on the ground, and the subsequent operations are fully automated, effectively improving the efficiency of wire traction when the large traction machine is loading and reducing time consumption.

[0032] It should be noted that the lifting mechanism 2 adopts mature lifting equipment, and can use structures such as screw lifting pairs and guide rail lifting pairs.

[0033] In one embodiment, to automate the feeding and docking of the wire traction device to the feed inlet of the large drawing machine, the wire traction device further includes a connecting component 5. The connecting component 5 includes a receiving pipe 52, a conveying wheel set 53, and a guide pipe 54. The receiving pipe 52 is positioned directly below the drop point of the wire guided by the tensioning component 4. When the tensioning component 4 drops the rod 6, the receiving pipe 52 can connect and guide the feeding direction of the rod 6. The conveying wheel set 53 is located at the discharge end of the receiving pipe 52 and actively conveys the rod 6 guided by the receiving pipe 52. The guide pipe 54 is located adjacent to the conveying wheel set 53 and is used to connect with the conveying wheel set 53 to convey the wire. The guide pipe 54 is used to connect to the feed inlet of the large drawing machine.

[0034] Understandably, the receiving pipe 52 receives the hanging rod 6 and guides it to the conveyor wheel set 53. The conveyor wheel set 53 then transports the rod 6 from the guide pipe 54 and directly connects it to the feed port of the large pulling machine for automatic feeding.

[0035] In one embodiment, in order to connect the clamping wheel assembly 3 and have the function of reversing the rod 6, the tensioning assembly 4 includes a mounting frame 41, a second telescopic member 42, an auxiliary wheel 43, a steering wheel 44, and a curved plate 45. The mounting frame 41 is disposed on the platform 1, the second telescopic member 42 is disposed on the mounting frame 41, the auxiliary wheel 43 is rotatably connected to the telescopic end of the second telescopic member 42, and the auxiliary wheel 43 is positioned opposite the steering wheel 44, and the auxiliary wheel 43 and the steering wheel 44 are positioned opposite each other to form a second gap, the second gap being directly above the first gap. The second telescopic member 42 is used to drive the auxiliary wheel 43 to move closer to or away from the steering wheel 44. The curved plate 45 is connected to the platform 1 through a bracket and is located above the steering wheel 44, used to guide the wire to hang downwards. When the clamping wheel assembly 3 moves to the tensioning assembly 4, the second gap aligns with the first gap, and the top of the rod 6 is inserted into the second gap. Then, the auxiliary wheel 43 is pushed by the second telescopic member 42, and the rod 6 is clamped by the steering wheel 44. Then, the rod 6 is driven to move upward by the rotation of the steering wheel 44 and enter the inner side of the curved plate 45, and changes direction along the curved plate 45.

[0036] Furthermore, the curved plate 45 bends upward in an arc shape from the second gap, passing over the steering wheel 44, and then bends downward to the other side of the steering wheel 44, thereby passing the rod 6 over the upper side of the steering wheel 44 and hanging down.

[0037] Understandably, both the steering wheel 44 and the self-driving wheel 34 are equipped with drive motors 3401 for active driving, enabling them to rotate actively to transmit the rod 6.

[0038] In one embodiment, in order to have a telescopic function, the telescopic frame includes a frame 31 and a first telescopic member 32. The frame 31 is connected to the lifting end of the lifting mechanism 2. The self-driving wheel 34 is rotatably connected to the frame 31. The first telescopic member 32 is disposed on the frame 31, and the driven wheel 33 is rotatably connected to the telescopic end of the first telescopic member 32. By extending or retracting the first telescopic member 32, the driven wheel 33 can be driven to move.

[0039] Understandably, the driven wheel 33 is installed inside the frame 31, while the first telescopic member 32 is installed outside the frame 31. A strip hole 401 is provided on the frame 31 to guide the direction of telescopic movement. Both the first telescopic member 32 and the second telescopic member 42 can be hydraulic push rods.

[0040] In one embodiment, to improve the success rate of material receiving, the receiving pipe 52 includes a first flared opening 521 and a bent pipe 522. The first flared opening 521 is located at the top of the bent pipe 522 and faces upward. The other end of the bent pipe 522 is bent to a horizontal position. Since the opening of the flared opening is outward, it has a large receiving range. When the tilt range of the rod 6 is within the receiving range of the flared opening, it can be guided to the bent pipe 522 below through the inverted conical surface of the flared opening. The diameter of the bent pipe 522 is set to correspond to the diameter of the rod 6 to guide the rod 6 to change direction.

[0041] Furthermore, the guide tube 54 includes a second flared opening 542 and a tube body 541. The large circular end of the second flared opening 542 is directly opposite the bottom end of the bent tube 522, and the other end of the second flared opening 542 is connected to the tube body 541. In order to avoid the rod 6 being skewed when it is conveyed by the conveyor wheel assembly 53, the guide tube 54 also uses a flared opening for connection, thereby improving the success rate of connection.

[0042] In one embodiment, to facilitate the installation of the connecting component 5, the connecting component 5 further includes a base frame 51, and the receiving pipe 52, the conveying wheel set 53 and the guide pipe 54 are installed on the base frame 51 from left to right, thereby forming an adjacent primary conveying relationship.

[0043] Understandably, if the conveying distance is too long, the conveyor wheel set 53 and guide tube 54 can be added in sections.

[0044] In one embodiment, the conveyor wheel assembly 53 includes a pair of rollers distributed vertically. Specifically, the two rollers are rotatably connected to the frame, which is connected to the base frame 51, and one roller is driven by a motor to achieve the conveying effect.

[0045] In one embodiment, annular grooves 301 are provided on the outer sides of the self-driving wheel 34, driven wheel 33, auxiliary wheel 43 and steering wheel 44. The rod 6 can be limited by the annular grooves 301 to make its guiding direction more accurate.

[0046] The specific workflow of this invention is as follows: The coiled rod 6 is placed below the clamping wheel assembly 3. The end of the rod 6 is pulled and placed into the first gap, about 15 cm above the first gap. Then, the driven wheel 33 is pushed by the first telescopic member 32 to clamp the rod 6 between the driven wheel 33 and the self-driving wheel 34. After clamping the rod 6, the lifting mechanism 2 raises the clamping wheel assembly 3, aligns the first gap with the second gap, and inserts the rod 6 into the second gap. The rod 6 in the second gap is clamped between the auxiliary wheel 43 and the steering wheel 44 by the second telescopic member 42. Then, the steering wheel 44 drives the rod 6 upward. The rod 6 enters the curved plate 45 and changes direction downward along the outer arc surface of the steering wheel 44 until it hangs down. The receiving pipe 52 receives the hanging rod 6 and guides it to the conveying wheel group 53. The conveying wheel group 53 conveys the rod and guides it with the guide pipe 54, directly connecting it to the feed port of the large drawing machine.

[0047] The entire workflow is now complete, and anything not described in detail in this specification is existing technology known to those skilled in the art.

[0048] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
