Description

Technical Field

[0002] With the continuous advancement of science and technology and the continuous innovation of process technology, the production of cross-linked cables provides the power industry with more efficient and safer cable products. Usually, after the cross-linking process is completed, the cable head needs to be pulled, and the cable core needs to be wrapped, metal shielded and outer sheathed.

[0003] However, the traditional way of tying the cable head has the possibility of loose tying and slipping, which may cause the cable head to slip and fall, resulting in production interruption and rework and stripping of the sheath. Use a saber saw to cut the cross-linked cable, and use the tying rope to repeatedly wrap around the cut to fix the cable head. However, since the force direction is not in the center, the cable head deviates from the center when entering the extruder head or pulling. Use a mesh cover to cover the cable end to complete the pulling. There is a dilemma that there is no mesh cover of the right size to use when the outer diameter of the cable is large. There is also the possibility of slipping due to insufficient friction during the pulling process due to the relatively smooth surface of the cross-linked core. Utility Model Content

[0039] With the cross-linking cable production, the power industry is provided with more efficient and safer cable products. Usually, after the cross-linking process is completed, the cable head needs to be pulled to wrap the cable core, metal shield and outer sheath. However, the traditional pulling method can easily cause the cable head to slip and fall, causing production interruption and rework and sheath stripping; even due to uneven force, the cable head is easy to deviate from the center during the pulling process.

[0040] In view of this, an embodiment of the present application provides a traction structure, which includes a traction assembly, a traction rod and a connecting assembly. The traction rod has a first end and a second end. The first end of the traction rod is connected to the connecting assembly, and the connecting assembly is used to be connected to the cable, and the second end of the traction rod is connected to the traction assembly. The connecting assembly includes an axial connector and a radial connector. The axial connector is connected to the radial connector, and one end of the axial connector is connected to the traction rod. Along the axial direction of the cable, the axial connector is also connected to the cable. Along the radial direction of the cable, the radial connector is connected to the cable. The cable is firmly connected to the traction rod through the connecting assembly, which ensures the stability and safety of the cable during the traction process, reduces the difficulty of operation, has a wide adaptability, is suitable for the traction of cables of various specifications, is easy to maintain and has low cost.

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only 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 creative work are within the scope of protection of this application.

[0042] Figure 1 This is a schematic diagram of the structure of the cable pulling device provided in an embodiment of the present application. Figure 2 A front view of a cable pulling device provided in an embodiment of the present application, Figure 3 This is a schematic diagram of the structure of the axial connecting member of the cable pulling device provided in an embodiment of the present application. Figure 4 A schematic diagram of the structure of the traction device of the cable traction device provided in an embodiment of the present application.

[0043] The present application provides a cable pulling system, which includes a pulling device 30, a cable 20, and a cable pulling device. The pulling device 30 is connected to the cable pulling device, and the pulling device 30 is used to pull the cable 20 along the axial direction. Figure 1 and Figure 4 As shown, the traction device 30 has two ends, one end of the cable 20 traction device 30 is connected to the traction device 30, and the other end of the cable 20 traction device 30 is connected to the cable 20. The cable 20 can be pulled in a preset direction by pulling the cable traction device through the traction device 30. It can be understood that the traction device 30 can be a power source, which transmits the traction force to the cable traction device, so that the cable 20 connected to the cable traction device is pulled and moved in a preset direction, thereby improving the efficiency and stability of the cable 20 traction.

[0044] It should be noted that in the embodiment of the present application, the traction device 30 may be a traction winding machine. Figure 4 As shown, the traction device 30 includes a motor 301, a fixing seat 302 and a winding disk 303. The motor 301 and the winding disk 303 are located on the fixing seat 302, and the motor 301 is used to control the winding disk 303 to rotate the traction rope 304 on the winding disk 303. One end of the traction rope 304 is fixedly connected to the winding disk 303, and the other end of the traction rope 304 can be connected to the first connecting member 110 of the traction assembly 100.

[0045] It can be understood that the motor 301 can be internally connected to the winding disk 303 through a bearing, and the motor 301 can control the winding disk 303 through tension, so that the traction rope 304 fixed on the winding disk 303 can be automatically wound under the action of the tension of the motor 301, thereby driving the cable traction device connected to the other end of the traction rope 304 to pull and move the cable 20 in a predetermined direction of movement.

[0046] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the cable pulling device includes a pulling structure 10, and the pulling structure 10 includes a pulling assembly 100, a pulling rod 200 and a connecting assembly 300. The pulling rod 200 has a first end and a second end. The first end of the pulling rod 200 is connected to the connecting assembly 300, and the connecting assembly 300 is used to be connected to the cable 20. The second end of the pulling rod 200 is connected to the pulling assembly 100. In this way, when the pulling device 30 is in operation, the pulling force can be smoothly transmitted to the cable 20 through the pulling rod 200, so that the cable 20 can be stably pulled in a predetermined direction under the action of the pulling device 30, and the pulling force can be evenly transmitted to avoid damaging the outer skin of the cable 20.

[0047] The connection assembly 300 includes an axial connection member 310 and a radial connection member 320, wherein the axial connection member 310 and the radial connection member 320 are connected, and one end of the axial connection member 310 is connected to the traction rod 200. The axial connection member 310 is also connected to the cable 20 along the axial direction of the cable 20. The radial connection member 320 is connected to the cable 20 along the radial direction of the cable 20. In this way, the stability and safety of the cable 20 during the traction process can be fully ensured. By fixing the cable 20 in both the axial and radial directions, the connection assembly 300 can fix the cable 20 in all directions, preventing the cable 20 from being damaged or falling off due to uneven force or external factors during the traction process, thereby improving the safety of the traction operation.

[0048] In some embodiments of the present application, Figure 2 As shown, the connection assembly 300 further includes a sleeve 330, the axial connector 310 and the radial connector 320 are located in the sleeve 330, and the axial connector 310 is located at one end of the sleeve 330, and the sleeve 330 is connected to the traction rod 200 through one end of the axial connector 310. The cable 20 is located at the other end of the sleeve 330, and the cable 20 is connected to the sleeve 330 through the other end of the axial connector 310.

[0049] like Figure 3 As shown, the axial connector 310 is further provided with a second opening 311 and a plurality of third openings 312, and the plurality of third openings 312 are symmetrically arranged around the second opening 311. It is understandable that the thread 210 of the traction rod 200 passes through the through hole of the cushion block 220 and is connected to the second opening 311 on the axial connector 310, and the cable 20 can be fixedly connected to the axial connector 310 by passing the screw 350 through the third opening 312.

[0050] It should be noted that in the embodiment of the present application, the number of the third openings 312 is six, but it is not limited to six, and can be any number, such as five or seven. The third openings 312 can be centrally symmetrical or axially symmetrical on the axial connector 310. The symmetrically opened third openings 312 can ensure that the axial connector 310 and the cable 20 are more firmly connected through the screws 350, so that the traction device 30 can further effectively prevent the cable 20 from falling off from the axial connector 310 during the pulling operation.

[0051] In some embodiments of the present application, Figure 2 As shown, the sleeve 330 is further provided with a plurality of first openings 340, and the radial connector 320 is located in the first openings 340 so as to connect the cable 20 to the sleeve 330. In a possible implementation, the inner diameter of the sleeve 330 may be larger than the outer diameter of the cable 20, and one end of the cable 20 is inserted into the sleeve 330, so that the inner wall of the sleeve 330 fits the outer surface of the cable 20. The cable 20 and the sleeve 330 are fixed by the radial connector 320, providing a radial tightening force to the cable 20 to prevent the cable 20 from being separated from the sleeve 330 during the traction process.

[0052] It should be noted that the number of the first openings 340 on the sleeve 330 may be the same as or different from the number of the radial connectors 320. In the embodiment of the present application, the number of the first openings 340 is set to nine and is arranged symmetrically along the radial direction of the sleeve 330, but is not limited to nine and symmetrical arrangements. For example, it can be set to eight and arranged asymmetrically. It is understandable that when the number of the first openings 340 on the sleeve 330 is arranged symmetrically, connecting the sleeve 330 to the cable 20 through the radial connector 320 can ensure that the force on the cable 20 in the radial direction during the traction process is more uniform, which is conducive to ensuring the stability of the connection between the sleeve 330 and the cable 20.

[0053] In some embodiments of the present application, Figure 2 As shown, a thread 210 is provided on one end of the traction rod 200, and the traction rod 200 is connected to the sleeve 330 through the axial connector 310 and the thread 210. In this way, the traction rod 200 is connected to the end of the axial connector 310 facing away from the cable 20 through the thread 210. A thread 210 is provided on the first end of the traction rod 200, and the thread 210 can pass through the second opening 311 on the cushion block 220, so that the narrow end of the cushion block 220 is in close contact with the traction rod 200. It can be understood that the length of the thread 210 along the extension direction of the traction rod 200 is much greater than the length of the cushion block 220 along the extension direction of the traction rod 200, so that the thread 210 passes through the second opening 311 of the cushion block 220 and is connected to the axial connector 310.

[0054] It should be noted that the outer peripheral surface of the thread 210 has a thread, so that the traction rod 200 is threadedly connected to the axial connector 310 through the thread 210, and the connection strength is high and not easy to loosen. The thread 210 is turned out by a lathe at the end of the traction rod 200, and the thread 210 and the traction rod 200 are integrally formed, and the connection between the thread 210 and the traction rod 200 is relatively smooth, which can effectively reduce the damage of the cable 20 caused by uneven connection during the traction process.

[0055] In some embodiments of the present application, Figure 1 and Figure 2 As shown, the connection assembly 300 further includes a cushion block 220, and the sleeve 330 is connected to one end of the axial connector 310 through the cushion block 220, and a through hole is provided on the cushion block 220, and the thread 210 of the traction rod 200 passes through the through hole and is connected to the axial connector 310. In this way, the cushion block 220 and the thread 210 can be detachably connected, thereby meeting the traction requirements of cables 20 of different specifications and types, and improving its versatility and adaptability.

[0056] Please continue reading Figure 2 One end of the pad 220 is connected to the first end of the traction rod 200, and the other end of the pad 220 is connected to the axial connector 310. In a possible implementation, the pad 220 has a narrow end and a thick end, wherein the narrow end of the pad 220 is connected to the traction rod 200, and the thick end of the pad 220 is connected to the axial connector 310.

[0057] It is understandable that the pad 220 can effectively disperse the stress generated during the traction process of the cable 20 and protect the traction rod 200 from damage. The thick end of the pad 220 increases the contact area between the connection assembly 300 and the cable 20, further improving the stability of the connection. In a possible implementation, the pad 220 can be a polyoxymethylene pad, but is not limited to a polyoxymethylene pad, and can also be a pad made of other rubber plastic materials.

[0058] It should be noted that the outer surface of the cushion block 220 forms an angle with the axial direction of the traction rod 200, and the angle is between 15° and 40°. For example, the angle formed by the outer surface of the cushion block 220 and the axial direction of the traction rod 200 may be 15° or 20°, etc. It is understandable that the angle formed between the cushion block 220 and the axial direction of the traction rod 200 helps to more evenly transmit the traction force to the cable 20, reducing the damage to the cable 20 caused by the uneven distribution of the traction force.

[0059] Please continue reading Figure 2The spacer 220 is also provided with a through hole (not shown in the figure), and the thread 210 passes through the through hole on the spacer 220 and is connected to the end of the axial connector 310 facing away from the cable 20. The thread 210 passes through the through hole of the spacer 220 and is threadedly connected to the axial connector 310. It should be noted that the size of the through hole on the spacer 220 should ensure that the thread 210 can pass smoothly, and ensure that the thread 210 and the axial connector 310 are well fixedly connected.

[0060] In some embodiments of the present application, Figure 1 and Figure 2 The traction assembly 100 includes a first connector 110 and two oppositely arranged traction plates 120, the traction plates 120 are located at the second end of the traction rod 200, and each traction plate 120 is provided with a connection hole 140, the first connector 110 is located in the connection hole 140, and the traction plate 120 is connected to the traction device 30 through the first connector 110. In this way, part of the traction device 30 can be fixedly connected to the traction plate 120 through the first connector 110, so that the traction force generated by the traction device 30 can be efficiently transmitted to the traction rod 200, thereby achieving traction of the cable 20 along a preset direction.

[0061] It should be noted that each traction plate 120 is provided with a connection hole 140, and the connection holes 140 on the two opposite traction plates 120 are located on the same axis, and the first connecting member 110 passes through the connection holes 140 on the two traction plates 120 to connect the front end of the traction rope 304 to the traction plate 120. The traction groove 130 can make the connection between the traction rope 304 of the traction device 30 and the traction rod 200 more tightly, and the traction device 30 and the traction rod 200 are not prone to slippage. In addition, the traction assembly 100 makes the traction rod 200 and the traction device 30 more compact, has high versatility and flexibility, and can be applied to traction devices 30 of different specifications.

[0062] In a possible implementation, the connection hole 140 on each traction plate 120 may be a smooth round hole. The first connection member 110 passes through the connection holes 140 on the two traction plates 120 to fix part of the traction device 30 in the traction groove 130. In another possible implementation, the connection hole 140 on each traction plate 120 may be an opening with a threaded inner wall. The first connection member 110 passes through the connection holes 140 on the two traction plates 120 to be threadedly connected to fix part of the traction device 30 in the traction groove 130.

[0063] It is understandable that when the connection hole 140 is a smooth round hole, the first connection member 110 can be easily passed through the connection hole 140 on the traction plate 120, and the fixing method is simple and effective, reducing the resistance when the first connection member 110 is inserted, making the entire fixing process smoother. When the connection hole 140 is an opening with a thread on the inner wall, it can have a higher fixing strength and stability, which is suitable for scenes with higher fixing requirements. At this time, the outer surface of the first connection member 110 is also provided with a pattern matching the thread. Through the threaded connection, it can ensure that the connection between the first connection member 110 and the traction plate 120 is tighter and less likely to get loose or shake.

[0064] It is understandable that the spacer block 220 and the axial connector 310 are all detachably connected to the traction rod 200 , and the traction operation of cables 20 of different sizes can be satisfied by replacing the spacer blocks 220 and the axial connector 310 of different sizes.
