Description

Technical Field

[0001] This invention relates to the field of high-voltage cable stripping technology, and in particular to a heated high-speed cable stripper. Background Technology

[0002] When installing high-voltage cable accessories, it is necessary to strip the cable's insulation shield. Currently, for insulation shields that cannot be peeled off, the common method is to scrape them off with a glass scraper. This method requires a significant amount of time to repair the cable insulation shield, and if used improperly, the glass scraper can cut the operator's hand. Furthermore, in winter, the cable insulation shield hardens, further increasing the difficulty of the operation and making it difficult to guarantee timely installation. In the emergency repair of submarine cables, the impact of the complex marine environment must be considered, and submarine cable repair projects place particular emphasis on timeliness; even an extra day of work time represents a substantial loss. Summary of the Invention

[0003] The technical problem this invention aims to solve is that cutting the fatigue layer of cable insulation is currently difficult, not very safe, and easily affected by external factors.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a heated high-speed cable stripper, including a main operating cylinder, wherein a plurality of first electric rollers are movably mounted on the main operating cylinder via a first internal support rod, an internal assembly ring is fixedly mounted on the inner side of the main operating cylinder via a second internal support rod, a plurality of second electrically controlled rollers are movably mounted on the inner side of the main operating cylinder via a third internal support rod, an electric heating ring controlled by a thermocouple module is fixedly mounted on the inner side of the internal assembly ring, an internal annular guide rail is fixedly mounted on the inner side of the main operating cylinder, and a retractable circular cutting blade is movably mounted inside the internal annular guide rail.

[0005] The main operating cylinder is welded and fixed with internal assembly brackets at the connection ends of the first and third internal support rods.

[0006] Both the first internal support rod and the third internal support rod include a tilting adjustment frame movably mounted on the internal assembly bracket and a lateral adjustment strut for controlling the tilting adjustment frame.

[0007] The retractable circular cutter includes an inner adjusting ring slidably mounted in an inner annular guide rail, an external adjusting motor fixed on the outer side of the main operating cylinder, an adjusting gear mounted on the output shaft of the external adjusting motor, an arc-shaped mounting groove on the inner side of the inner adjusting ring, an arc-shaped adjusting arm movably mounted in the arc-shaped mounting groove, an inner adjusting support rod for controlling the arc-shaped adjusting arm, and a first cutting blade movably mounted at the end of the arc-shaped adjusting arm.

[0008] A pressure control module is provided at the end of the arc-shaped adjusting arm and the connection end of the first cutting blade.

[0009] A plurality of elastic peeling claws are fixedly mounted on the outer arc-shaped surface of the first electric roller.

[0010] The arc-shaped adjusting arm has an arc-shaped opening inside.

[0011] The arc-shaped opening is equipped with an auxiliary adjusting arm and an auxiliary support rod for controlling the auxiliary adjusting arm.

[0012] A second cutting blade is installed at the end of the arc-shaped adjusting arm.

[0013] The main operating cylinder has side heat insulation covers fitted at the openings on both sides.

[0014] The beneficial effects of this invention are:

[0015] (1) The heating type fast cable stripper of the present invention heats the cable insulation shield and conductor respectively by setting a resistance heating layer and an electromagnetic induction heating layer inside, and the non-peelable insulation shield is transformed into a peelable insulation shield by the heating device, which greatly reduces the difficulty of operation.

[0016] (2) By operating inside the main operating cylinder, interference from external factors can be greatly avoided, thus improving the peeling efficiency;

[0017] (3) By adopting a built-in adjustable structure design, it can be adapted to cables of different diameters, greatly improving the adaptability of the equipment;

[0018] (4) By using an internal movement method to cut the cable, the requirements for the operating environment are not high, no additional drive unit is required, and the drive efficiency is improved;

[0019] (5) The insulation shielding layer outside the cable is quickly cut and separated after internal heating without damaging the cable;

[0020] (6) By adopting a variety of structural designs for the cutting device, the cutting methods become more diverse;

[0021] (7) By using thermocouple units, the temperature of the insulation shield can be detected in real time, ensuring that the cable will not be damaged due to excessive temperature. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] Figure 1 , Figure 2 and Figure 3 The heating-type high-speed cable stripper shown includes a main operating cylinder 1. The main operating cylinder 1 is movably mounted with a plurality of first electric rollers 3 via a first internal support rod 2. An internal mounting ring 5 is fixedly mounted on the inner side of the main operating cylinder 1 via a second internal support rod. A plurality of second electrically controlled rollers 7 are movably mounted on the inner side of the main operating cylinder 1 via a third internal support rod 6. An electric heating ring 9 controlled by a thermocouple module 8 is fixedly mounted on the inner side of the internal mounting ring 5. An internal annular guide rail 10 is fixedly mounted on the inner side of the main operating cylinder 1. A retractable circular cutting blade 11 is movably mounted inside the internal annular guide rail 10.

[0029] The electric heating ring 9 consists of a resistance heating layer and an electromagnetic induction heating layer. It heats the cable insulation shield and conductor respectively, transforming the non-removable insulation shield into a removable one through the heating device.

[0030] Working principle: The cable is inserted into the main operating cylinder 1 through one side opening. The first electric roller 3 controls the cable to be transported inside the main operating cylinder 1. Then, the internal annular guide rail 10 drives the internal retractable circular cutting plate 11 to cut the insulation shield from the insulation. Then, the second electric roller 7 tears it off, thus stripping the insulation shield.

[0031] To facilitate internal assembly, the main operating cylinder 1 is welded and fixed with internal assembly brackets at the connection ends of the first internal support rod 2 and the third internal support rod 6.

[0032] To facilitate the adjustment of the installation angles of the first internal support rod 2 and the third internal support rod 6, both the first internal support rod 2 and the third internal support rod 6 include a flip-adjustment frame 12 movably mounted on the internal assembly bracket and a lateral adjustment strut 13 for controlling the flip-adjustment frame 12.

[0033] The lateral adjustment strut 13 controls the tilting adjustment frame 12 to tilt and adjust by extending and retracting, thereby changing the distance between the first electric roller 3 and the second electric control roller 7 and the cable.

[0034] The first electric roller 3 contacts the cable surface to control the cable to move and transport inside the main operating drum 1, while the second electric roller 7 rolls up the stripped insulation shielding layer.

[0035] To facilitate electronic control adjustment, the telescopic circular cutter 11 includes an inner adjusting ring 111 slidably mounted in the inner annular guide rail 10, an external adjusting motor 112 fixed on the outer side of the main operating cylinder 1, an adjusting gear 113 mounted on the output shaft of the external adjusting motor 112, an arc-shaped mounting groove opened on the inner side of the inner adjusting ring 111, an arc-shaped adjusting arm 114 movably mounted in the arc-shaped mounting groove, an inner adjusting support rod 115 for controlling the arc-shaped adjusting arm 114, and a first cutting blade 116 movably mounted at the end of the arc-shaped adjusting arm 114.

[0036] The external adjustment motor 112 drives the adjustment gear 113 to rotate, and then uses the lifting gear 113 to control the rotation of the inner adjustment ring 111, thereby changing the angle of the arc-shaped adjustment arm 114 and the inner adjustment support rod 115. The arc-shaped adjustment arm 114 drives the first cutting blade 116 at the end to squeeze and peel off the insulation shield on the surface of the cable, while the inner adjustment support rod 115 controls the flip angle of the arc-shaped adjustment arm 114 by extending and retracting.

[0037] To facilitate monitoring and control of the cutting depth, a pressure control module 117 is provided at the end of the arc-shaped adjusting arm 114 and the connection end with the first cutting blade 116.

[0038] When the arc-shaped adjusting arm 114 flips to control the first cutting blade 116 to make contact with the insulation shield on the outer surface of the cable, the pressure control module 117 will sense the downward pressure and judge the cutting depth by the magnitude of the downward pressure, thereby avoiding over-cutting.

[0039] To improve the separation efficiency of the insulation shield, a plurality of elastic peeling claws 14 are fixedly mounted on the outer arc-shaped surface of the first electric roller 3.

[0040] To facilitate lateral installation, the arc-shaped adjusting arm 114 has an arc-shaped opening inside.

[0041] To facilitate storage and unfolding, an auxiliary adjustment arm 15 and an auxiliary support rod 16 for controlling the auxiliary adjustment arm 15 are movably fitted inside the arc-shaped opening.

[0042] The auxiliary support rod 16 controls the tilting of the auxiliary adjusting arm 15 by telescoping, so that it can be brought into contact with the insulation shield of the cable surface layer as needed.

[0043] To cut the insulating shield in another way, a second cutting blade 17 is installed at the end of the arc-shaped adjusting arm 15.

[0044] To prevent internal heat from escaping, side heat insulation covers 18 are fitted on the openings on both sides of the main operating cylinder 1.

[0045] By installing heat insulation covers on both sides of the main operating cylinder 1 according to the outer diameter of the cable, heat leakage can be effectively reduced, thereby reducing energy consumption.

[0046] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
