[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other in any way.

[0033] During the production of wire ropes, when the wire of a wire roll is used up, it is necessary to replace it with a full wire roll. At this time, the tail of the wire of the previous wire roll needs to be connected with the head of the next wire roll to produce the wire rope.

[0034] In the related art, two steel wires can be tightened together manually with the help of pliers. However, this operation method has low efficiency, and different operators have different standards when operating, and the connection quality of the steel wires cannot be guaranteed.

[0035] In order to improve work efficiency, some manufacturers use laser welding to connect steel wires, but laser welding equipment is expensive.

[0036] Based on this, an exemplary embodiment of the present application provides a steel wire connection device for steel wire rope production, in which a guide assembly and a rotating assembly are provided. The rotating assembly can tighten the separated steel wires together in a spiral winding manner, and the guide assembly can guide the movement direction of the steel wire to prevent the steel wire from escaping from the winding assembly. In this way, the separated steel wires can be tightened together with high tightening efficiency and unified standards, so that the connection quality of the steel wires is uniform. At the same time, the device has a simple structure and low production and maintenance costs.

[0037] An exemplary embodiment of the present application provides a steel wire connecting device for steel wire rope production, such as Figure 1 As shown, the wire connecting device for wire rope production includes a guide assembly 10 and a rotating assembly 20. The first steel wire 90A of the previous wire coil and the second steel wire 90B of the next wire coil are successively wound around the rotating assembly 20, and then the rotating assembly 20 rotates, tightening the first steel wire 90A and the second steel wire 90B together in a spiral winding manner.

[0038] The guide assembly 10 is used to guide the movement of the first steel wire 90A and the second steel wire 90B. When the first steel wire 90A is wound around the rotating assembly 20, the first steel wire 90A and the second steel wire 90B have a certain elasticity, so the guide assembly 10 can prevent the steel wires from escaping from the rotating assembly 20 during the winding process and the subsequent tightening process.

[0039] The rotating assembly 20 is used to drive the first steel wire 90A and the second steel wire 90B to rotate, so that the separated first steel wire 90A and the second steel wire 90B are tightened together in a spirally wound manner.

[0040] In one embodiment, the guide assembly 10 includes a first guide plate 101 , a second guide plate 102 and a fixing seat 103 . The second guide plate 102 is fixedly disposed above the first guide plate 101 , and the fixing seat 103 is fixedly disposed on the second guide plate 102 .

[0041] like Figure 5As shown, the first guide plate 101 includes a first guide portion 1011, a second guide portion 1013, and a connecting portion 1012 connecting the first guide portion 1011 and the second guide portion 1013. A hook-shaped groove 1014 is formed between the first guide portion 1011 and the second guide portion 1013. During the winding process, the hook-shaped groove 1014 can prevent the first steel wire 90A and the second steel wire 90B from being separated.

[0042] During the process of winding the second steel wire 90B onto the rotating assembly 20 and the rotating assembly 20 driving the first steel wire 90A and the second steel wire 90B to rotate and tighten, since the second steel wire 90B is elastic, in order to prevent the second steel wire 90B from escaping from the device, the second guide portion 1013 of the first guide plate 101 is tilted downward at a certain angle, for example, it can be tilted 15°, 20°, 30°, etc., to prevent the second steel wire 90B from escaping from the device.

[0043] like Figure 6 As shown, the fixing base 103 includes an integrally formed first fixing portion 1031, a second fixing portion 1032, and a bearing 201 mounting portion 1033. The two ends of the second fixing portion 1032 are respectively connected to the first fixing portion 1031 and the bearing 201 mounting portion 1033. An arcuate groove 1034 is provided between the second fixing portion 1032 and the bearing 201 mounting portion 1033. During the winding process, the arcuate groove 1034 can prevent the first steel wire 90A and the second steel wire 90B from separating.

[0044] like Figures 1 to 4 As shown, the rotating assembly 20 includes a bearing 201, a rotating shaft 202 and a rotating wheel 203. A bearing 201 mounting hole is provided on the fixed seat 103. Specifically, a bearing 201 mounting hole is provided on the bearing 201 mounting portion 1033. The bearing 201 is installed in the bearing 201 mounting hole. The rotating shaft 202 passes through the bearing 201. The lower end of the rotating shaft 202 is provided with a rotating wheel 203. The upper end of the rotating shaft 202 can be connected to a driving unit for driving the rotating assembly 20 to rotate. The rotating assembly 20 can also be driven manually or by a robot.

[0045] like Figure 7 As shown, a plurality of rotating teeth 2031 are provided on the rotating wheel 203. The rotation direction of the rotating teeth 2031 is clockwise, and the ends of the rotating teeth 2031 extend in the clockwise direction, which can effectively prevent the first steel wire 90A and the second steel wire 90B from escaping from the gap between the rotating teeth 2031.

[0046] During operation, the rotating wheel 203 rotates clockwise. In one embodiment, to prevent the rotating wheel 203 from rotating counterclockwise, the bearing 201 is configured as a one-way bearing 201. The bearing 201 can only rotate clockwise, not counterclockwise. This prevents the rotating wheel 203 from rotating backwards and prevents the first steel wire 90A and the second steel wire 90B, which are spirally wound and tightly together, from separating again.

[0047] In one embodiment, the device further includes a driving unit, which is disposed at the top end of the rotating shaft 202 . The driving unit may be a motor to drive the rotating assembly 20 to rotate.

[0048] In one embodiment, if Figure 4 As shown, the device further includes a screw nut 50 and a spring 40. The spring 40 is sleeved on the rotating shaft 202, and the screw nut 50 is disposed at the top of the rotating shaft 202. The manipulator can engage the screw nut 50 and drive the rotating assembly 20 to rotate. The spring 40 can buffer the impact force generated by the manipulator when engaging the screw nut 50, preventing the manipulator from exerting excessive impact on the device and causing damage to the device.

[0049] In order to facilitate the docking of the manipulator and the screw nut 50, a cross groove is provided at the end of the screw nut 50. Further, a groove cross section of the cross groove can be trapezoidal, with a large upper opening and a small lower opening to facilitate the docking of the manipulator and the screw nut 50.

[0050] like Figure 8 As shown, in order to prevent the impact generated during the docking of the robot and the device from damaging the device, a groove 2021 is provided on the top circumferential surface of the rotating shaft 202, a pin hole is provided on the screw nut 50, a positioning pin is inserted from the pin hole, and the end of the positioning pin is provided in the groove 2021. The vertical stroke of the positioning pin is the length of the groove 2021, which can effectively prevent the robot from damaging the device.

[0051] like Figures 1 to 4 As shown, in order to prevent the first steel wire 90A and the second steel wire 90B from detaching from the rotating assembly 20 during the tightening process, the steel wire connecting device for wire rope production also includes a clamping portion 30, and the clamping portion 30 is fixedly arranged on the fixed seat 103. For example, the clamping portion 30 is fixedly arranged on the second fixed portion 1032 of the fixed seat 103, and the clamping portion 30 is used to clamp the steel wires to prevent them from falling off.

[0052] In one embodiment, the pressing portion 30 is a spring 40. One end of the pressing portion 30 is fixed to the fixing seat 103 by a fastener, and the other end of the pressing portion 30 is raised and spaced apart from the fixing seat 103. The raised portion facilitates the insertion of the first steel wire 90A and the second steel wire 90B under the pressing portion 30.

[0053] In one embodiment, an upwardly protruding portion is provided between the fixed end and the tilted end on the clamping portion 30, and a space for accommodating the first steel wire 90A and the second steel wire 90B is formed between the upwardly protruding portion and the fixed seat 103. The vertical height of the space can be slightly smaller than the diameter of the first steel wire 90A and the second steel wire 90B. At this time, the clamping portion 30 can clamp the first steel wire 90A first wound on the rotating component 20, and at the same time will not cause the clamping portion 30 to tilt upward at a too large angle to affect the second steel wire 90B wound on the rotating component 20 later.

[0054] In one embodiment, the device further includes a spacer (not shown) that is mounted on the rotating shaft 202 and positioned between the rotating wheel 203 and the bearing 201. The spacer is tightly fitted with the bearing 201 and the rotating wheel 203 to prevent the first steel wire 90A and the second steel wire 90B from being entangled with the rotating shaft 202 during winding.

[0055] In one embodiment, an adjustment spacer 60 is further provided between the first guide plate 101 and the second guide plate 102 for adjusting the distance between the first guide plate 101 and the second guide plate 102 to accommodate steel wires of different diameters.

[0056] The working process of the steel wire connecting device for steel wire rope production of the present application is as follows: a manipulator or a human being grabs the first steel wire 90A and winds it onto the rotating assembly 20, and presses one end of the head of the first steel wire 90A under the pressing portion 30, and then a manipulator or a human being grabs the second steel wire 90B and winds it onto the rotating assembly 20, and presses one end of the head of the second steel wire 90B under the pressing portion 30. After that, the manipulator docks the screw nut 50, drives the rotating device to rotate, or manually drives the rotating device to rotate, or the motor drives the rotating device to rotate, driving the first steel wire 90A and the second steel wire 90B to rotate, wind and tighten together. After tightening, the first steel wire 90A and the second steel wire 90B are connected together in a spiral winding manner, and then a certain external force is applied to the first steel wire 90A, and the first steel wire 90A and the second steel wire 90B that are tightened together are separated from the gap between the rotating teeth 2031.

In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the article or device comprising the element.

[0058] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.
