Description

Technical Field

[0001] The utility model relates to the technical field of stripping devices, in particular to an armored saw cutting device for portable insulated cables. Background Technique

[0002] In the construction process of power engineering, the high-voltage cable joint process requires stripping the insulating layer of the cable. When stripping, a certain length of the outer semiconductive layer of the high-voltage cable should be stripped according to the predetermined depth requirement to expose the insulating layer. At the same time, it is required that the finally stripped cable insulating layer does not have defects such as unevenness, scratches, and burrs. The commonly used stripping methods mainly include manual stripping and mechanical stripping. The manual stripping method has a high labor intensity, and it is difficult to control the stripping accuracy, which requires extremely high technical levels of the stripping personnel and has extremely low efficiency. While mechanical stripping does not require manual labor and has the advantages of easy control of stripping accuracy and high efficiency.

[0003] However, due to the large size, excessive weight, and inconvenient carrying of general stripping instruments, and due to structural limitations, they can only strip cables with a small bending degree. In actual situations, sometimes cables with a large bending degree are encountered. At this time, general stripping instruments will not be able to effectively strip the cables, and there is also the drawback that the cutting knife is fixed and can only achieve circular cutting and cannot achieve vertical cutting.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , a portable armored saw cutting device for insulated cables in this embodiment, includes a fixing plate 1, a turntable 2 is rotatably installed on the top of the fixing plate 1, a cutting component 3 is arranged on the top of the turntable 2, three groups of support components 4 are arranged at the bottom of the fixing plate 1, and linear guide rails 5 are fixedly installed on both the left and right sides of the top of the turntable 2;

[0024] The cutting assembly 3 includes a mounting frame 301. The mounting frame 301 is slidably mounted between two linear guide rails 5. A support base 302 is fixedly mounted on the top of the mounting frame 301. A connecting seat 303 is rotatably mounted on the front of the support base 302. A support cylinder 304 is rotatably mounted inside the connecting seat 303. A cutting wheel 305 is rotatably mounted on the support cylinder 304. Tensile springs 306 are fixedly mounted on both the left and right sides of the top of the mounting frame 301. A rotating shaft 307 is rotatably mounted inside the support base 302. A support plate 308 is inductively mounted at the bottom of the connecting seat 303. A side plate 309 is fixedly mounted on the bottom of the support plate 308. An adjusting bolt 310 is rotatably mounted inside the side plate 309. A slider 311 is slidably mounted on the bottom of the support plate 308. A push plate 312 is fixedly mounted on the front of the slider 311;

[0025] The support assembly 4 includes a connecting shaft 401. The connecting shaft 401 is fixedly mounted on the bottom of the fixing plate 1. A moving plate 402 is movably mounted on the side of the connecting shaft 401. A knob 403 is rotatably mounted between the two moving plates 402. A pulley 404 is rotatably mounted between the two moving plates 402. An adjusting screw 405 is fixedly mounted at the end of the knob 403. A connecting plate 406 is fixedly mounted at the end of the adjusting screw 405.

[0026] In this embodiment, a cutting hole is opened at the central position of the fixing plate 1 and the cable passes through the cutting hole during the cable cutting process. The cutting assembly 3 can slide above the turntable 2 under the traction of the linear guide rails 5. A rotating shaft is fixedly mounted on the back of the connecting seat 303 and the rotating shaft is rotatably mounted inside the support base 302. The cutting wheel 305 is designed on the outer periphery above the cutting hole.

[0027] In this embodiment, the tensile spring 306 is used to apply a tensile force to the mounting frame 301. When peeling and cutting cables of different models, under the action of the spring torque, the mounting frame 301 will always be close to the cable. The adjusting bolt 310 is used to adjust the position of the slider 311. The push plate 312 is arranged below the cutting wheel 305 and is used to push the cable and control the cutting depth during the cutting process. The horizontal and vertical cutting of the cable skin is completed by the cutting assembly 3 with an adjustable angle. The circumferential cutting of the cable skin is realized by manually rotating the cutting assembly 3. At the same time, the push plate 312 is set to push the cable to control the contact area between the cable and the cutting wheel 305 so as to achieve the purpose of controlling the cutting depth.

[0028] In this embodiment, three support components 4 are arranged in a ring around the cutting hole. A rotary auxiliary rod is installed on the turntable 2 to drive the rotation of the turntable 2. The outer surface of the adjusting screw 405 is threadedly connected to the connecting shaft 401 and passes through the connecting shaft 401. The connecting plate 406 is fixedly installed between the two moving plates 402. When locking the cable, the moving plate 402 can be driven to move on the connecting shaft 401 by rotating the adjusting screw 405, and the distance between the three pulleys 404 can be controlled to fix cables of different models. By setting three groups of support components 4 to fix the cable to be cut, and using three pulleys 404 to extrude and fix the cable, the cable is always kept at the center position of the fixed plate 1 for cutting. At the same time, the positions of the three pulleys 404 can be adjusted rotatably, which is convenient for cutting cables of different models.

[0029] By adopting the above technical solution, when cutting and peeling the cable, the cable is passed through the cutting hole, and the cable is locked by the three pulleys 404. Rotating the adjusting bolt 310 drives the slider 311 to slide forward or backward on the support plate 308, applying a thrust to the cable. The thrust can control the distance between the cable and the cutting wheel 305, thereby controlling the cutting depth. Rotating the connecting seat 303 can adjust the angle of the cutting wheel 305 to achieve the conversion between longitudinal cutting and transverse cutting. For longitudinal cutting, the cutting wheel 305 is rotated to a position perpendicular to the turntable 2, and the fixed plate 1 is pulled downward to move the cutting wheel 305 on the outer surface of the cable for cutting. For transverse cutting, the cutting wheel 305 is rotated to a position parallel to the turntable 2, and the turntable 2 is rotated for transverse circumferential cutting.
