[0002] Cross-linking of cable insulation materials is a common production process, primarily used to improve the heat resistance, mechanical strength, and chemical stability of insulation materials. In cable manufacturing, the most commonly used cross-linking method is to form a three-dimensional network structure between polymer chains through chemical or physical means. This process is called cross-linking.

DETAILED DESCRIPTION

[0030] Reference herein to an embodiment means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present invention. The appearance of such a phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments. Example 1

[0031] A cross-linking device for the insulation production of power cables, such as Figure 1 and Figure 2 As shown, it includes a mounting frame 1, a cooling frame 2 is rotatably connected to the inside of the mounting frame 1, an air inlet 21 is opened on the upper part of the cooling frame 2, and an air outlet 22 is opened on the lower part of the cooling frame 2. The front and rear sides of the mounting frame 1 are slidably connected with pins 3 for locking and limiting the cooling frame 2. It also includes: an extension mechanism 4, the extension mechanism 4 is arranged on the cooling frame 2, and is used to extend and adjust the guide stroke of the cooling frame 2; the clamping mechanism 5, the clamping mechanism 5 is arranged on the extension mechanism 4, and is used to clamp and guide the cable and provide conveying thrust when necessary.

[0032] It should be noted that when performing cable insulation cross-linking operations, this device can be used to guide the mixing of cables and insulating colloids. First, the device is installed at the cable discharge position so that the cable can directly enter the cooling frame 2. Then, the guiding length of the cooling frame 2 is adjusted by the extension mechanism 4 according to the distance between the devices. In this process, the cable is stably guided by the clamping mechanism 5, and nitrogen is introduced through the air inlet 21, so that the cooling frame 2 can cool the cable. If the cable is not powered enough and cannot move normally, the clamping mechanism 5 can also push the cable to move and discharge, thereby improving the discharge smoothness.

[0033] like Figure 1 and Figure 3 As shown, the extension mechanism 4 includes an extension cylinder 41, and the upper and lower parts of the cooling frame 2 are both slidably connected with the extension cylinder 41. The extension cylinder 41 is used to extend the distance of the cooling frame 2. A first drive motor 42 is installed on the left side of the cooling frame 2. A first mounting seat 44 is installed on the left side of the cooling frame 2. The first mounting seat 44 is rotatably connected to the output shaft of the first drive motor 42. A first gear 43 is connected to the output shaft of the first drive motor 42. A bidirectional screw rod 45 is rotatably connected to the left part of the cooling frame 2, and another first gear 43 is connected to the middle part of the bidirectional screw rod 45. The two first gears 43 are meshed with each other, and the bidirectional screw rod 45 is threadedly connected to the extension cylinder 41.

[0034] It should be noted that when guiding the cable, the output shaft of the first drive motor 42 can be controlled to rotate according to the distance and height difference between the devices, so that the first gear 43 interacts with each other. At this time, the bidirectional screw rod 45 will start to rotate, and then adjust the position of the extension tube 41, so that the extension tube 41 can be docked and adapted with the device to achieve a quick adjustment effect.

[0035] like Figure 1 、 Figure 4 、 Figure 5 and Figure 6As shown, the clamping mechanism 5 includes a fixed disk 51, the top of the extension tube 41 on the upper side is connected to the fixed disk 51, the top of the fixed disk 51 is slidably connected to four sliding members 52, the inner sides of the sliding members 52 are rotatably connected to rotating wheels 53, the rotating wheels 53 are used to clamp and guide the cable, the rotating wheels 53 are made of flexible material, the bottom of the fixed disk 51 is connected to four fixing members 54 corresponding to the positions of the sliding members 52, the fixing members 54 are slidably connected to the adjacent sliding members 52, the sliding members 52 Springs 55 are connected between adjacent fixing members 54, a driving motor 56 is installed on the front sliding member 52, and a second gear 57 is connected to the output shaft of the driving motor 56. A fixed sleeve 59 is connected to the left side of the front rotating wheel 53, and a clamping member 510 is rotatably connected to the fixed sleeve 59. Elastic members 511 are connected between the clamping member 510 and the fixed sleeve 59. A third gear 58 is slidably connected between the clamping members 510, and the third gear 58 and the second gear 57 are engaged with each other.

[0036] It should be noted that when the cable is conveyed downward along the cooling frame 2, the action of the spring 55 will cause the sliding member 52 to drive the rotating wheel 53 to always fit the cable, thereby clamping and guiding the cable. When the cable moves, it is affected by the friction force and the rotating wheel 53 will rotate inward to adapt to the direction of cable movement. As the front rotating wheel 53 rotates inward, it will drive the fixed sleeve 59 to rotate in the same direction, thereby causing the clamping member 510 to move synchronously. During the movement, the clamping member 510 will be squeezed by the third gear 58 and flipped to the side close to the fixed sleeve 59. At this time, the elastic member 5 11 will be compressed, and the clamping parts 510 will be disengaged from the third gear 58, that is, the fixed sleeve 59 is in an idling state and cannot affect the third gear 58. When the cable is insufficiently powered and cannot be discharged normally, the drive motor 56 can be started at this time. The rotation of the output shaft of the drive motor 56 will drive the second gear 57 to rotate. At this time, the second gear 57 will drive the third gear 58 to rotate. The rotation of the third gear 58 will drive the clamping parts 510 to rotate, so that the fixed sleeve 59 drives the rotating wheel 53 to rotate, thereby giving the cable a normal driving force, so that the cable can continue to move and discharge. Example 2

[0037] On the basis of Example 1, Figure 1 and Figure 7 As shown, an adjustment mechanism 6 is also included, and the adjustment mechanism 6 includes a fixed seat 61. The front and rear sides of the mounting frame 1 are connected to the fixed seat 61, and a worm 62 is rotatably connected to the fixed seat 61. The left end of the worm 62 is connected to a power-assisting ring, and the front and rear ends of the cooling frame 2 are connected to a worm wheel 63. The worm wheel 63 is engaged with the adjacent worm 62. A pulley assembly 64 is connected between the right sides of the worm 62. The pulley assembly 64 consists of a pulley and a transmission belt. The right side of the worm 62 is connected to a pulley, and a transmission belt is wound around the pulleys.

[0038] It should be noted that due to the position deviation between the devices, in order to ensure the normal transportation of the cable, the angle of the cooling frame 2 needs to be adjusted. At this time, the pin 3 needs to be pulled out to the left first so that the pin 3 no longer locks the cooling frame 2. Then, the worm 62 on either side is rotated. Driven by the pulley assembly 64, the worm 62 on the other side will rotate synchronously, thereby synchronously adjusting the worm wheel 63, causing the angle of the cooling frame 2 to deflect, thereby adapting to the position deviation between different devices.

[0039] like Figure 1 and Figure 8 As shown, it also includes an anti-overtightening mechanism 7, which includes a second mounting seat 73. The second mounting seat 73 is connected to the upper extension cylinder 41, and a second drive motor 71 is installed on the right side of the second mounting seat 73. The fourth gear 72 is connected to the output shaft of the second drive motor 71, and the right part of the second mounting seat 73 is rotatably connected to the rotating shaft 74. The upper and lower parts of the rotating shaft 74 are also connected to the fourth gear 72. The two fourth gears 72 on the lower side are engaged with each other. A toothed rotating disk 75 is rotatably connected to the fixed disk 51, and the toothed rotating disk 75 is engaged with the fourth gear 72 on the upper side, and the toothed rotating disk 75 is slidably connected to the sliding member 52.

[0040] It should be noted that in order to prevent the sliding member 52 and the rotating wheel 53 from cooperating abnormally, resulting in excessive clamping of the cable, so that the cable cannot be transported normally, the output shaft of the second drive motor 71 can be controlled to rotate, so that the second gear 57 drives the rotating shaft 74 to rotate, and the rotating shaft 74 drives the fourth gear 72 on the upper side to rotate, thereby rotating the toothed rotating disk 75. At this time, the toothed rotating disk 75 will cause the sliding member 52 to slide inward synchronously to avoid the rotating wheel 53 clamping the cable too tightly, affecting the normal transportation of the cable.

[0041] like Figure 1 and Figure 9 As shown, a control mechanism 8 is also included, and the control mechanism 8 includes an air valve 81. The air valve 81 is installed at the air inlet 21. The air valve 81 is used to control the amount of nitrogen entering. Monitoring components 82 are connected to the front and rear sides of the upper part of the cooling frame 2. The monitoring components 82 are located on the upper side of the adjacent air valve 81 and are used to detect the internal temperature of the cooling frame 2.

[0042] like Figure 1 and Figure 10 As shown, a connecting mechanism 9 is also included. The connecting mechanism 9 includes a mounting block 91. The lower side of the lower extension tube 41 is connected to the mounting block 91. A plurality of fasteners 92 for splicing are threadedly connected to the mounting block 91.

[0043] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall equally within the scope limited by the appended claims of the application.
