Description

Technical Field

[0001] The present invention relates to the field of cable cutting, in particular to a cable cutter and a cutting method. Background Art

[0002] Low-voltage lines are power lines with a rated voltage of less than 1kV. Low-voltage lines include low-voltage overhead lines, low-voltage overhead insulated lines, low-voltage cable lines and indoor distribution lines. They are used to directly transmit electric energy to low-voltage electrical equipment and are an important part of the low-voltage distribution system. The cables used in low-voltage cable lines are generally single-core or multi-core cables. When the staff inspect or repair them, they may encounter the following problems:

[0003] 1. During maintenance, when the cable is used for a long time and the end is seriously corroded, it needs to be cut and then connected. This requires disconnecting the cable end from the cable connection first, and then cutting off the corroded part. When cutting off the internal copper wire of the cable, there may be residual current flowing even after the power is turned off. This requires certain protective measures to avoid electric shock;

[0004] 2. The aging of old cables may cause the internal copper wires of the cables to be exposed, which is prone to leakage in rainy days. In severe cases, short circuits or even combustion may occur. During the maintenance process, the burned part needs to be cut off after it is burned out, and the cables at both ends need to be connected. If it is a multi-core cable, you need to pay attention to the wear of the blade on the internal copper wire when stripping it. If the wear is severe, it may cause problems with the line.

[0005] In view of this, we propose a cable cutter and a cutting method. Summary of the invention

[0018] As a further improvement of this technical solution, the method is as follows:

[0019] S1: First, the staff cuts off the power to the entire low-voltage line, and then places the end of the cable into the cutting room through the ring fixture;

[0020] S2: After placing the cable in the cutting chamber, the second slide block is used to slide the cable to complete the cutting;

[0021] S3: The cut cables are transported into the stripping chamber by the rotation of the annular fixing member, and the cables are transported to the depth of the stripping chamber by manpower;

[0022] S4: When the cable is conveyed to the bottom of the first slide block, the multiple cables inside the multi-core cable are spread out by expanding and contracting the spreading assembly;

[0023] S5: Finally, the operator rotates the rotating cover and uses the extension and retraction of the No. 2 telescopic rod to complete the stripping of the cable insulation and take out the cable.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. In the cable cutter, the contraction of the No. 2 telescopic rod pushes the No. 1 slider to slide upward, and at the same time, the No. 2 sliders on both sides of the No. 1 slider expand outward under the drive of the No. 1 slider, and at the same time, the square fixing part and the No. 2 connecting column at the bottom thereof are contracted inward, and at the same time, the connecting rod at the end close to the No. 2 connecting column uses the supporting column as a supporting point, thereby driving the connecting rod at the end away from the No. 2 connecting column to rotate inward, and finally, the semicircular blades on both sides are used to cut off the burnt or aged part of the cable.

[0026] 2. In the cable cutter, the No. 1 telescopic rod is extended, and the arc-shaped clamping piece and the clamping gasket are driven to clamp the middle part of the cable. At the same time, the No. 2 telescopic rod is extended to push the No. 1 slider downward, and the No. 2 slider is retracted inward, and the No. 1 connecting column is driven to slide inward. At the same time, the stripping ring slides downward on the No. 1 connecting column until the annular blade on the stripping ring wraps the outer insulation of the cable. The operator holds the rotating cover and rotates the rotating cover to make the annular blade slide on the cable insulation to split the insulation, and then the No. 2 telescopic rod is retracted to complete the stripping of the cable insulation.

[0027] 3. In the cable cutter, while the No. 2 telescopic rod is extended downward to push the No. 1 slider, the No. 3 telescopic rod is extended and drives the expansion component at its bottom to move downward, so that the conical part uses the pointed tip at the bottom to penetrate into the multi-core cable. Because the expansion piece around the conical part can expand outward to expand the multiple cables around the inside of the cable, the operator rotates the rotating cover as mentioned above to complete the stripping of the insulation skin of the multi-core cable.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The present invention takes into account that in most of the prior art, when a low-voltage line fails, it is necessary to climb up the electric pole to repair the cable. The aging of the old cable may cause the copper wire inside the cable to be exposed, which is prone to leakage in rainy days, and in severe cases, short circuit or even combustion. During the repair process, the burned part needs to be cut off after burning out, and the cables at both ends need to be connected. If it is a multi-core cable, it is necessary to pay attention to the wear of the blade on the internal copper wire when stripping. If the wear is severe, it may cause problems in the line. Therefore, it is necessary to use the cutting component 36 to cut the cable, and the cable insulation skin is stripped by sliding the No. 1 slider 33 up and down;

[0045] Among them, some cables may not be single-core cables, but multi-core cables. The multi-core cables may not be stripped cleanly, resulting in series connection when the cables at both ends are subsequently connected. Therefore, it is necessary to spread out the multiple cables inside the multi-core cable and strip off the insulation at the ends.

Fig. 9As shown, the cutting assembly 36 is fixedly connected to the bottom of the middle part of the square fixing member 351, and the cutting assembly 36 includes a No. 2 connecting column 361. One end of the No. 2 connecting column 361 is fixedly connected to the bottom of the square fixing member 351, and the other end of the No. 2 connecting column 361 is rotatably connected to one end of a connecting rod 362, and the other end of the connecting rod 362 is fixedly connected to a semicircular blade 363. The middle part of the connecting rod 362 is rotatably connected to one end of a supporting column 131, and the other end of the supporting column 131 is fixedly connected to the top of the inner wall of the bottom cover 13. The cutting chamber 2 is rotatably connected to a rotating wheel 21 at the bottom of one side close to the peeling chamber 1, and the rotating wheel 21 is fixedly connected to two opposite sides. One end of the annular fixing member 221, the other end of the annular fixing member 221 is fixedly connected to one end of the rotating rod 222, the other end of the rotating rod 222 is rotatably connected to the fixing ring 23, the semicircular blade 363 is arranged on the inner side of the upper end of the cutting chamber 2, the inner sides of the No. 2 sliders 34 on both sides are provided with sliding grooves 341, the two sides of the No. 1 slider 33 are provided with raised strips, the raised strips are matched with the sliding grooves 341, and the No. 1 slider 33 is slidably connected to the inner sides of the No. 2 sliders 34 on both sides, the outer wall of the lower end of the No. 2 slider 34 is fixedly connected with a strip-shaped raised block 342, the inner wall of the connecting member 32 is provided with a slide rail 322, the slide rail 322 is matched with the strip-shaped raised block 342;

[0048] It can be seen that when it is necessary to cut and strip the aging cable, Figure 2-11 As shown, the operator puts the end of the aged cable into the cutting chamber 2 through the bottom of the cutting chamber 2. At this time, the semicircular blades 363 on both sides are in the expanded state, not the closed state. At this time, the contraction of the No. 2 telescopic rod 31 pushes the No. 1 slider 33 to slide upward, and at the same time, the No. 2 sliders 34 on both sides of the No. 1 slider 33 expand outward under the drive of the No. 1 slider 33, and at the same time drive the square fixing piece 351 and the No. 2 connecting column 361 at its bottom to contract inward, and at the same time, the connecting rod 362 at the end close to the No. 2 connecting column 361 uses the support column 131 as the support point, thereby driving the connecting rod 362 at the end away from the No. 2 connecting column 361 to rotate inward, and finally the burnt or aged part of the cable is cut off by the semicircular blades 363 on both sides;

[0049] It should be noted that: Figure 3 As shown, because the No. 1 slider 33 is in a trapezoidal block shape as a whole, the inclined surfaces of the No. 2 sliders 34 on both sides thereof match the inclined surfaces of the No. 1 slider 33. When the No. 1 slider 33 slides upward, a thrust force is formed toward the No. 2 sliders 34 on both sides, so that the No. 2 sliders 34 on both sides slide outwardly to both sides. Moreover, because the strip-shaped protrusions 342 match the slide rails 322, the No. 2 slider 34 can only slide horizontally along the track of the slide rails 322 inside the connecting member 32. On the contrary, when the No. 1 slider 33 slides downward, the middle part of the No. 2 slider 34 will slide in the direction of the No. 1 slider 33.

[0050] After the cable end is cut off, the cable is pulled out and rotated downward with the annular fixing piece 221, driving the cable to rotate 180 degrees and then go deep into the stripping chamber 1 from the bottom of the stripping chamber 1, and then the operator pushes the cable inward until the cable end is pushed to the bottom of the connecting piece 32 and stops. At this time, the No. 1 telescopic rod 121 extends and drives the arc-shaped clamping piece 122 and the clamping gasket 123 to clamp the middle part of the cable. At the same time, the No. 2 telescopic rod 31 extends to push the No. 1 slider 33 downward, the No. 2 slider 34 contracts inward, and drives the No. 1 connecting column 331 to slide inward. At the same time, the stripping ring 332 slides downward on the No. 1 connecting column 331 until the annular blade 3321 on the stripping ring 332 wraps the outer insulation of the cable. The operator holds the rotating cover 11 and rotates the rotating cover 11 to make the annular blade 3321 slide on the cable insulation to cut the insulation, and then the No. 2 telescopic rod 31 contracts to complete the stripping of the cable insulation. It should be noted that: when the cable cutting is completed, the annular fixing piece 221 brought out after the cable is pulled out is rotated 180 degrees by the rotation of the rotating rod 222, and its fixing ring 23 will not change direction.

[0051] Embodiment 2

[0052] In order to strip the multi-core cable, this embodiment is different from the embodiment 1 in that: Figure 5-6 As shown, wherein: a No. 1 connecting column 331 is slidably connected to both sides of the bottom of the No. 1 sliding block 33, a stripping ring 332 is slidably connected to the inner side of the No. 1 connecting column 331 on both sides, and an annular blade 3321 is arranged inside the stripping ring 332 on both sides, one end of a No. 3 telescopic rod 333 is fixedly connected to the center position of the bottom of the No. 1 sliding block 33, and a conical member 3341 is fixedly connected to the other end of the No. 3 telescopic rod 333, and a plurality of opening pieces 3342 are rotatably connected to the outer wall of the conical member 3341, and a spring 3343 is arranged between the opening piece 3342 and the conical member 3341;

[0053] It can be seen from this that when stripping a multi-core cable, while the No. 2 telescopic rod 31 extends downward to push the No. 1 slider 33, the No. 3 telescopic rod 333 extends and drives the expansion component 334 at its bottom to move downward, so that the conical part 3341 uses the pointed tip at the bottom to penetrate into the multi-core cable. Because the expansion piece 3342 around the conical part 3341 can expand outward and rotate, the multiple cables around the inside of the cable are expanded. Then, the operator rotates the rotating cover as mentioned above to complete the stripping of the insulation skin of the multi-core cable.

[0054] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
