Description

Technical Field

[0001] This utility model relates to the technical field of cable cutting equipment, specifically a cable cutting device for high-altitude power maintenance. Background Technology

[0002] A cable cutting device is a specialized tool for cutting power cables, typically used in the installation, maintenance, and emergency repair of power systems. It applies high pressure mechanically or hydraulically to quickly and cleanly cut cables of various specifications, ensuring a smooth cut and preventing damage to the internal conductors. Cable cutting devices are generally portable, easy to operate, and highly safe, making them suitable for complex working environments such as high altitudes and confined spaces. Cable cutting devices play a crucial role in high-altitude power maintenance. High-altitude working environments are complex and pose high safety risks; traditional cutting tools are often inefficient and pose safety hazards.

[0003] In existing technologies, such as the portable cable cutter disclosed in patent number CN220066655U, a fixed plate is used. A movable plate rotates the fixed plate, changing its angle. The serrated blade remains perpendicular to the fixed plate. As the fixed plate rotates, the fixed plate becomes more vertical, and the tip of the serrated blade gradually becomes horizontal, cutting the cable. While this type of cable cutter is easy to operate, the cable is prone to shifting, making it difficult to guarantee the cutting position. Furthermore, the lack of positioning and fixation at both ends of the cut cable causes the cut end to fall directly, swinging and potentially causing damage and danger.

[0004] Therefore, an improved cable cutting device is needed to enhance the stability of cable cutting. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example: This utility model provides a technical solution for a cable cutting device for high-altitude power maintenance, such as... Figures 1-6 As shown, it includes a fixed rod 100, a fixed plate 300 connected to one end of the fixed rod 100, a first handle 200 connected to the other end of the fixed rod 100, a tangent assembly 500 disposed on the top surface of the fixed plate 300, a flip-clamp assembly 400 rotatably connected to the top surface of the fixed plate 300, and a support assembly 600 slidably sleeved on the outer wall of the fixed rod 100. Two sets of flip-clamp assemblies 400 are mirror images of the vertical centerline of the fixed plate 300. The support assembly 600 has a T-shaped structure and is provided with a horizontal structure and a vertical structure. The vertical structure of the support assembly 600 is connected through the inside of the tangent assembly 500. The two sides of the horizontal structure of the support assembly 600 are slidably connected to the bottom of the two sets of flip-clamp assemblies 400 respectively.

[0029] The flip-clamp assembly 400 includes a rotating column 410 rotatably connected to the top surface of the fixed plate 300, a first connecting plate 420 fixed to the side wall of the rotating column 410, a wire clamping component 430 rotatably connected to the inside of the first connecting plate 420 on the side away from the rotating column 410, a slide rail 421 fixed to the bottom surface of the first connecting plate 421, and one side of the transverse structure of the extension assembly 600 slidably connected to the inside of the slide rail 421.

[0030] By setting two sets of flip-clamping components 400 rotatably connected to the fixed plate 300, and using two sets of wire clamping components 430 to clamp the cable, the extension component 600 is moved to flip and open the two sets of flip-clamping components 400, thereby pulling the two sets of wire clamping components 430 apart, keeping the cable in the middle taut, and then using the wire cutting component 500 to cut the taut cable, ensuring the stability of the cable cutting.

[0031] After the cable is cut, it is not immediately separated. The timing of releasing the cut cable can be selected, which further improves the stability of cable cutting.

[0032] Furthermore, the wire clamping component 430 includes a fixing bolt 432 rotatably connected inside the first connecting plate 420, a first spring 433 sleeved on the outer wall of the fixing bolt 432, a rotating locking plate 431 connected to the top of the fixing bolt 432, a first wire clamping plate 437 fixed to one side of the rotating locking plate 431, a motor 434 disposed on the bottom surface of the rotating locking plate 431, a screw 435 connected to the rotating top of the motor 434, and a lifting rod threaded onto the outer wall of the screw 435. The lifting plate 436, the second clamping plate 438 fixed to the side wall of the lifting plate 436, the guide rod 439 fixed to the bottom surface of the lifting plate 436, the guide rod 439 slidably connected to the inside of the rotating lock plate 431, the screw 435 rotatably connected to the inside of the rotating lock plate 431, the top end of the first spring 433 connected to the bottom surface of the first connecting plate 420, the top surface of the first clamping plate 437 is provided with a clamping groove 4371, and the second clamping plate 438 is mirror-mounted on the top of the first clamping plate 437;

[0033] By placing and clamping the cable between the first clamping plate 437 and the second clamping plate 438, and by rotating the fixing bolt 432 to adapt to the direction of the cable when the connecting plate is opened, until the cable between the two sets of clamping components 430 remains taut, the stability of the cable clamping and the flexibility of operation are ensured.

[0034] Furthermore, an anti-slip piece 4372 is embedded and fixed inside the clamping groove 4371. The anti-slip piece 4372 has an arc-shaped structure, and multiple anti-slip pieces 4372 are spaced apart.

[0035] By providing an anti-slip piece 4372 inside the cable clamping groove 4371, the anti-slip piece 4372 can prevent the cable from sliding when the cable is clamped inside the cable clamping groove 4371, thereby further improving the stability of the cable clamping and positioning.

[0036] Furthermore, the flip-clamp assembly 400 also includes a guide plate 440 fixed to the top surface of the first connecting plate 420, a bolt 450 that passes through and connects the guide plate 440 and the inside of the rotating column 410, a second spring 460 sleeved on the outer wall of the bolt 450, one end of the second spring 460 being connected to the side wall of the rotating column 410, one side of the rotating locking plate 431 having an arc-shaped structure, and the side wall of the arc-shaped structure of the rotating locking plate 431 having multiple locking slots 4311, one end of the bolt 450 being inserted into the locking slot 4311;

[0037] After the cable is flexibly clamped by the first clamping plate 437 and the second clamping plate 438, the flipping clamping component flips open and roughly straightens the cable. Then, the plug 450 is inserted into a locking groove 4311, and the cable is further opened to be completely straightened, which further improves the stability of the cable straightening operation.

[0038] like Figures 1-6As shown, the support assembly 600 includes a second positioning cylinder 610 sleeved on the outer wall of the fixed rod 100, a second connecting plate 630 fixed to the top surface of the second positioning cylinder 610, a positioning bolt 620 penetrating and connected inside the second connecting plate 630 and the second positioning cylinder 610, an inner support plate 640 vertically fixed to one side of the second connecting plate 630, a roller 650 rotatably connected to the top surface of the inner support plate 640, and a reinforcing rib 660 fixed between the side wall of the second connecting plate 630 and the side wall of the inner support plate 640. Two rollers 650 are provided about the vertical center line of the inner support plate 640. The rollers 650 are tactilely connected to the inside of the slide rail 421, and the second connecting plate 630 is slidably connected to the inside of the tangent assembly 500.

[0039] By sliding the second positioning cylinder 610 on the fixed rod 100, the inner support plate 640 is moved horizontally, which drives the roller 650 to slide on the slide rail 421. At the same time, during the sliding process, the two sets of flip clamp components 400 are opened, so that the cable is straightened. The opening operation is flexible and convenient.

[0040] Furthermore, the tangent assembly 500 includes a fixed base 510 fixed to the top surface of the fixed plate 300, a flip groove 511 opened on the top surface of the fixed base 510, a limiting groove 512 opened on the bottom surface of the fixed base 510, a first positioning cylinder 520 rotatably connected inside the flip groove 511, a connecting rod 530 slidably inserted inside the first positioning cylinder 520, a reciprocating cutter 540 fixed to one end of the connecting rod 530, a second handle 550 fixed to the other end of the connecting rod 530, and a second connecting plate 630 slidably connected inside the limiting groove 512.

[0041] By sliding the connecting rod 530 inside the first positioning cylinder 520 using the second grip 550, the reciprocating cutter 540 is adjusted to move to the position of the taut cable. At the same time, the first positioning cylinder 520 is flipped inside the flipping groove 511, thereby controlling the reciprocating cutter 540 to flip and cut the cable, which improves the convenience and stability of cable cutting.

[0042] Specifically, the worker holds the first handle 200 and moves the first clamping plate 437 and the second clamping plate 438 of the two sets of clamping components 430 to the position of the cable to be cut, so that the cable enters the clamping groove 4371 of the two first clamping plates 437. The motor 434 is started to drive the screw 435 to rotate, which drives the lifting plate 436 to descend, so that the second clamping plate 438 cooperates with the first clamping plate 437 to clamp the cable, so that the cable cutting position is between the two sets of clamping components 430.

[0043] Then slide the second positioning cylinder 610 on the fixed rod 100, pull the second connecting plate 630 to slide inside the limiting groove 512 of the fixed seat 510, so that the inner support plate 640 moves horizontally and the roller 650 slides inside the slide rail 421, so that the two second connecting plates 630 rotate and unfold, almost stretching and straightening the cable, and inserting the plug 450 into the nearest locking groove 4311 at the end. Then continue to move the second positioning cylinder 610 so that the cable is completely straightened, and rotate the positioning plug 620 to fix the second positioning cylinder 610 on the fixed rod 100.

[0044] Restart the reciprocating cutter 540, hold the second handle 550 and push the connecting rod 530 to slide inside the first positioning cylinder 520 to move the reciprocating cutter 540 to the top of the cable. Then, the first positioning cylinder 520 rotates inside the flip groove 511 of the fixed seat 510, causing the reciprocating cutter 540 to flip and cut the cable. After cutting, start the motor 434 to drive the second clamping plate 438 to separate from the first clamping plate 437 and release the cut cable.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
