Description

Technical Field

[0001] The utility model mainly relates to the field of cable deviation adjustment mechanisms, in particular to a deviation adjustment fixing bracket for a medium-voltage cross-linked polyethylene cable production line. Background Art

[0002] In cable production, both domestic and international production lines, eccentricity adjustment of the inner, insulation, and outer shield layers is typically accomplished using two sets of perpendicular screws. Adjusting the tightness of the screws adjusts the die head's internal mold. This adjustment method requires exceptionally high technical skill and extremely short adjustment times, requiring highly skilled workers to perform. To better control eccentricity, most production lines utilize a German SIKORA deflectometer approximately one meter below the die head for non-destructive testing of the cable. The deflectometer measures the thickness of each layer in the corresponding position, allowing manual adjustment of the eccentricity of the inner, insulation, and outer shield layers.

[0003] Manual adjustment requires high levels of skill and proficiency from production line technicians, easily resulting in unsatisfactory eccentricity and resulting in scrap. Furthermore, the adjustment accuracy is low, making it unsuitable for current automated production requirements. To address this issue, we developed an automatic centering device using a servo drive mechanism, secured to the extruder head via a mounting frame. However, the existing manual centering bracket is not compatible with the automatic centering device, necessitating the design of a new mounting structure to ensure stable cable alignment during production. Utility Model Content

[0004] In order to solve the deficiencies of the prior art, the utility model provides a medium-voltage cross-linked polyethylene cable production line eccentricity adjustment fixing bracket, which can complete the stable installation of the cable eccentricity automatic adjustment mechanism and realize the eccentricity adjustment for the cable extrusion process.

[0019] The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the contents of this invention, those skilled in the art may make various changes or modifications to the present invention, and that such equivalent forms also fall within the scope defined in this application.

[0020] like Figure 1-4 As shown, the utility model discloses a fixed support for adjusting the eccentricity of a medium-voltage cross-linked polyethylene cable production line, comprising a left support 1 and a right support 2. The left support 1 and the right support 2 are butt-jointed and installed. Compared to the monolithic structure of conventional manually adjustable supports, the left and right supports 1 and 2 of this device are divided into two distinct halves. The left support 1 is an isosceles right triangle frame, while the right support 2 is a semicircular frame. The structure of the right support 2 and the left support 1 is substantially the same as that of the manually adjustable support. The left support 1 is used to mount a pair of servo drive mechanisms to adjust the cable eccentricity on the X and Y axes.

[0021] Specifically, a left mounting groove 11 is provided in the left bracket 1, and a right mounting groove 21 is provided in the right bracket 2. When the left bracket 1 is docked with the right bracket 2, the left mounting groove 11 and the right mounting groove 21 are docked, serving as the installation position of the connecting bracket. A left semicircular opening 12 is provided on the side of the left mounting groove 11 facing the right bracket 2, and a right semicircular opening 22 is provided on the side of the right mounting groove 21 facing the left bracket 1. When the left bracket 1 is docked with the right bracket 2, the left semicircular opening 12 and the right semicircular opening 22 are docked to form a circular mounting channel. After the left bracket 1 is docked with the right bracket 2, the circular mounting channel serves as a through hole for cable extrusion, and an insulation adjustment core is installed on the machine head, so that the interference fine-tuning of the insulation adjustment core is completed by the drive of the servo drive mechanism, thereby adjusting the eccentricity of the extruded cable.

[0022] Ear plates 23 are provided at both ends of the right bracket 2, and fastening through holes 24 are provided on the ear plates 23. Threaded holes 13 corresponding to the fastening through holes 24 are provided at both ends of the left bracket 1. When the left bracket 1 is docked with the right bracket 2, the fastening through holes 24 are coaxial with the threaded holes 13. By fastening with bolts, the left bracket 1 and the right bracket 2 can be fastened together to be fixed on the machine head. The left mounting groove 11 and the right mounting groove 21 are used to install the connecting bracket. A number of fastening bolts are evenly arranged on the connecting bracket in a circular pattern, and the insulating adjusting core can be fastened by the fastening bolts. The connecting bracket can be displaced in the mounting groove, and the displacement of the connecting bracket is driven by a pair of vertically mounted servo drive mechanisms. Driven by the servo drive mechanism, the connecting bracket can be driven to displace in the plane of the mounting groove, thereby adjusting the eccentricity of the cable extrusion.

[0023] A pair of left fastening channels 14 are provided within the left mounting slot 11 of the left bracket 1. The left fastening channels 14 correspond to the two fastening bolts on the left side of the connecting bracket. A right-angle wrench can be inserted through the left fastening channels 14 to tighten or remove the fastening bolts on that side. The left fastening channels 14 are rectangular holes with rounded corners, which ensure a more stable structure for the left bracket 1. A pair of right fastening channels 25 are provided on the outer circumference of the right bracket 2. The right fastening channels 25 extend into the right mounting slot 21. The right fastening channels 25 correspond one-to-one with the two fastening bolts on the connecting bracket on that side, and the right fastening channels 25 are coaxial with the corresponding fastening bolts, so that the fastening and removal of the fastening bolts on that side can be completed through the right fastening channels 25.

[0024] The angle between the two left fastening channels 14 is 90 degrees, and the angle between the two right fastening channels 25 is 90 degrees. When the left bracket 1 and the right bracket 2 are docked, the angle between the adjacent left fastening channels 14 and right fastening channels 25 is 90 degrees. This structural design ensures that the tightening force of the fastening bolts on the insulation adjustment core is more uniform, ensuring the stability of the cable eccentricity adjustment.

[0025] Adjustment holes 15 perpendicular to the sides are provided on both sides of the left bracket 1. Servo drives are installed on both sides of the left bracket 1, and the adjustment screws of the servo drives pass through the adjustment holes 15. There are mounting threaded holes on both sides of each adjustment hole 15 for fastening the servo drive mounting base.

[0026] Specifically, the bottom of both sides of the left bracket 1 has a mounting platform 17 perpendicular to the bottom edge, and the threaded hole 13 on the left bracket 1 is opened on the mounting platform 17. The mounting platform 7 is equivalent to cutting off the two bottom corners of the left bracket 1, saving installation space and streamlining the volume of the left bracket 1.

[0027] The left mounting groove 11 is adjacent to the side of the left bracket 1 and has an inner side parallel to the side of the left bracket 1 . The inner side is used to cooperate with the adjusting slider structure of the adjusting bracket to provide an installation space for the movement of the adjusting bracket.

[0028] More specifically, a left sink 16 is provided on the left bracket 1 , and a right sink 26 is provided on the right bracket 2 . The provision of the sinks has a certain weight-reducing effect.
