Description

Technical Field

[0001] This utility model belongs to the field of cable production and application technology, specifically relating to a cable laying device for producing high flame-retardant and cold-resistant medium-voltage power cables. Background Technology

[0002] High flame-retardant and cold-resistant medium-voltage power cables have excellent flame-retardant properties, which can reduce the spread of fire in the event of a fire and protect the safe operation of the power system. The specially designed cold-resistant outer sheath enables the cable to maintain normal performance in low-temperature environments, making it suitable for medium-voltage power transmission systems in cold regions or low-temperature environments.

[0003] Meanwhile, the steel-tape armor enhances the cable's tensile, compressive, and impact resistance, making it suitable for use in complex environments; such as power supply and transmission in urban power grids, industrial and mining enterprises, and construction sites. It is especially suitable for cold regions or locations requiring flame-retardant properties, such as shopping malls, theaters, train stations, airports, and other densely populated areas.

[0004] In the production process of the aforementioned cables, there are production steps involving inkjet coding or spraying protective agents. This necessitates the use of corresponding cable delivery devices and inkjet coding / protective agent spraying equipment. For example, patent number 202020989772.3 and authorization announcement number CN212276897U disclose an active cable delivery device, comprising a first delivery metal frame, a second delivery metal frame, and a concave metal track. A circular roller positioned between the first and second delivery metal frames has cable wound around its surface. A rotary motor is mounted on the upper surface of a metal horizontal plate fixed to the right side of the second delivery metal frame. A metal base is mounted on the lower surface of both the first and second delivery metal frames, and a metal slider is fixed to the lower surface of the metal base. This invention solves the problems of cable joints shifting left and right as the roller rotates during the cable laying process in special cable laying devices by setting a metal base, metal slider, metal concave track, circular ball bearing, L-shaped metal rod, cable outlet, hot air blower, second circular groove, and second ball bearing. These problems include the need for manual correction, the limited functionality of the laying device, and the risk of damaging the surface of the cable after it has been coated with protective agent and printed with markings.

[0005] Analysis revealed that while it can complete an active defense line with a single cable, it suffers from low cable laying efficiency and uncontrollable cable tension during the active cable laying process.

[0006] Therefore, based on the above problems, this utility model provides a cable laying device for producing high flame-retardant and cold-resistant medium-voltage power cables. Utility Model Content

[0024] Example 1

[0025] like Figure 1 The high flame-retardant and cold-resistant medium-voltage power cable production cable laying device shown consists of a base plate 100, a vertical box 101, a set of horizontal lugs 102, a drive unit 20, and a set of cable drum rotating units 30.

[0026] A vertical housing 101 is mounted on a base plate 100. A set of horizontal lugs 102 are symmetrically arranged on the upper two outer walls of the vertical housing 101. A drive unit 20 is mounted on the upper part of the vertical housing 101 through a set of horizontal lugs 102 and is located at a set of cable drum rotating parts 30 to provide power. A set of cable drum rotating parts 30 is mounted on both sides of the vertical housing 101, and cable drums are placed on the set of cable drum rotating parts 30 respectively (not shown in the figure, which does not affect the disclosure of the technical solution of this application).

[0027] The working principle is as follows: the cable drums are fixedly installed on the cable drum rotating part 30. At this time, the drive part 20 is started. The drive part 20 drives the cable drum rotating part 30 to rotate the fixed cable drums, realizing active double-sided cable release. One end of the cable is introduced into the inkjet printing equipment and the protective agent spraying equipment.

[0028] In addition, the drive unit 20 preferably includes a motor frame 200 that spans a set of horizontal lugs 102, a servo motor 201 mounted on the motor frame 200, a coupling 202 mounted on the servo motor 201, a first bearing seat 203 disposed on the upper end face of the vertical housing 101, a drive shaft 204 with one end connected to the coupling 202 and the other end passing through the first bearing seat 203 and the vertical housing 101 in sequence, and a drive gear 205 mounted on one end of the drive shaft 204;

[0029] The power transmission process described above is as follows: the servo motor 201 is started, and the servo motor 201 drives the drive shaft 204 and the drive gear 205 to rotate synchronously through the coupling 202, providing rotational power to the cable drum rotating part 30 respectively.

[0030] In addition, preferably, a set of cable drum rotating parts 30 includes a second bearing seat 300 disposed on the outer walls of both sides of the vertical box 101 and located below a set of horizontal lug seats 102, a driven shaft 301 mounted on the vertical box 101 through the second bearing seat 300, a driven bevel gear 302 disposed at one end of the driven shaft 301 and meshing with the drive gear 205, a cable drum positioning plate 304 disposed at the other end of the driven shaft 301, an adjusting screw sleeve 303 disposed on the driven shaft 301 and located on one side of the cable drum positioning plate 304, and a cable drum pressure plate 305 and a fastening nut 306 disposed on the adjusting screw sleeve 303;

[0031] Rotation after power transmission: The driven bevel gear 302, which meshes with the drive gear 205, drives the driven shaft 301 to rotate synchronously. At this time, the cable drum, which is fixed by the cable drum positioning plate 304, adjusting screw sleeve 303, cable drum pressure plate 305, and fastening nut 306, rotates to actively release the cable (the cable drum is placed horizontally on the adjusting screw sleeve 303, and one end abuts against the cable drum positioning plate 304. At this time, rotate the fastening nut 306 until one side of the cable drum pressure plate 305 abuts against the other end of the cable drum. Continuously tighten the fastening nut 306 to complete the fixing of the cable drum).

[0032] Example 2

[0033] Based on Example 1, such as Figure 2 , Figure 3 and Figure 4 The high flame-retardant and cold-resistant medium-voltage power cable production cable laying device shown also includes a vertical column fixing plate 400 symmetrically arranged on one end face of the base plate 100, a vertical column 401 symmetrically arranged on the vertical column fixing plate 400, a counterweight tensioning block 402 fitted on the vertical column 401, and an anti-detachment block 403 arranged on the vertical column 401.

[0034] The counterweight tensioning block 402 is made of rubber or stainless steel. The cable (not shown in the figure, but it does not affect the disclosure of the technical solution of this application) is led out from below. Its own weight presses down on the cable to complete the downward tensioning action of the cable.

[0035] In addition, the preferred high flame-retardant and cold-resistant medium-voltage power cable production cable laying device also includes a cable groove 4021 set on the outer wall of the symmetrical center line of the counterweight tensioning block 402. The cable (not shown in the figure, which does not affect the disclosure of the technical solution of this application) is led out from the cable groove 4021. During the laying process, the position of the cable does not shift horizontally, so as to achieve stable cable laying.

[0036] In addition, such as Figure 5 The high flame-retardant and cold-resistant medium-voltage power cable production cable laying device shown also includes a vertical plate 500 symmetrically arranged on both sides of one end face of the base plate 100 and located between the vertical column fixing plates 400, and a wear-resistant bushing support seat 501 arranged at one end of the vertical plate 500 and used in conjunction with the driven shaft 301.

[0037] The driven shaft 301 passes through the wear-resistant bushing support 501, and the inside of the wear-resistant bushing support 501 is coated with lubricating grease. The above design can enhance the load-bearing capacity of the cable drum rotating part 30, so that it will not deform and is durable during rotation, and achieve the purpose of safe active cable release.
