Description

Technical Field

[0001] This invention relates to the field of cable laying, and more specifically, to a cutting device and method for laying aluminum alloy cables. Background Technology

[0002] Aluminum alloy cable is a mature, high-tech, environmentally friendly, energy-saving, and green power cable. It not only completely replaces traditional copper core cables in terms of electrical and safety performance, but more importantly, it costs less than 50% of traditional copper core cables while meeting the same electrical performance requirements. This saves project investors significant investment costs in power facilities, aligning with my country's development theme of building a conservation-oriented society. It is green, energy-saving, economical, and environmentally friendly. Furthermore, in practical applications, aluminum alloy cables weigh only half that of copper core cables under equivalent conditions, and have good flexibility. Current technology often involves directly cutting aluminum alloy cables with scissors, which is difficult to align with the cable, causing it to easily deviate, and is time-consuming and labor-intensive.

[0003] To address this technical problem, Chinese Patent Application No. 20191110448.9 discloses a cutting device and method for laying aluminum alloy cables. The device uses a hydraulic rod to drive a blade to cut the aluminum alloy cable, and a mounting base and a fixing block are provided to fix the cable.

[0004] In practical use, this device cannot indiscriminately cut cables of different thicknesses, nor can it measure the length of the cable to be cut. Traditional cutting devices require users to visually inspect or use other length measuring tools for assistance. Visual inspection can easily lead to cable waste, and using other length measuring tools for cable cutting is also inconvenient. This device uses a close-range cutting method, which can easily damage the mounting base. The mounting base needs to be disassembled and replaced frequently depending on its wear. When cutting thicker and stiffer cables, the close-range cutting head of the telescopic rod can easily cause the cutting to stop or result in an incomplete cut. Furthermore, the straightening component cannot straighten the cut section of cable. If the cut section of cable is twisted, it can easily lead to cutting errors.

[0005] Therefore, a cutting device and cutting method for aluminum alloy cable laying are proposed. Summary of the Invention

[0006] To address the problems existing in the prior art, the present invention aims to provide a cutting device and method for laying aluminum alloy cables. By setting a sliding clamping mechanism and an adapting mechanism, the present invention can achieve indiscriminate cutting of cables of different thicknesses.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0014] Furthermore, the auxiliary sliding mechanism includes roller grooves located at the four vertices of the front and rear outer surfaces of the functional rod inside the first slide groove; a first support rod is fixedly connected to one side of the inner surface of each of the eight roller grooves; and rollers are rotatably connected to the outer circular surfaces of each of the eight first support rods.

[0015] Furthermore, the length measuring mechanism includes a rotation meter installed on the inner surface of one side of the roller groove and a fourth slide groove extending from the inside of the functional rod to the upper outer surface; a push-button switch is fixedly connected to the lower inner surface of the fourth slide groove, and a third spring is fixedly connected to the lower inner surface of the fourth slide groove at a position outside the push-button switch, and the upper end of the third spring is fixedly connected to the lower outer surface of the slide rod; a microcontroller is installed inside the U-shaped base at a position away from the first slide groove; a display screen is installed inside the U-shaped base at a position below the microcontroller.

[0016] Furthermore, the close-to-cutting mechanism includes two second telescopic rods fixed to the inner surface of one side of the U-shaped base and a motor base fixed to the inner surface of the other side of the U-shaped base; one end of each of the two second telescopic rods is fixed to a tension fixing mechanism; the interior of the motor base extends to one side of its outer surface and has a motor slot; a second motor is fixed to one side of the inner surface of the motor slot; a second transmission rod is fixed to the output end of the second motor; a replacement mechanism is fixed to one end of the second transmission rod; a blade is slidably connected to the outer surface of the replacement mechanism; a sliding switch is slidably connected to the rounded corner of one side of the outer surface of the U-shaped base.

[0017] Furthermore, the tensioning and fixing mechanism includes a second base plate fixed to one end of the second telescopic rod; a fifth sliding groove is formed on the inner surface of the second base plate extending to one side; a third telescopic rod is fixed to the inner bottom of the fifth sliding groove; a second slider is fixed to the upper end of the third telescopic rod; a first motor is fixed to the inside of the second slider; a first transmission rod is fixed to the output end of the first motor; a rotating rod is fixed to one end of the first transmission rod; a second support rod is fixed to one side of the outer surface of the second base plate; a second roller is rotatably connected to the outer circular surface of the second support rod, and an anti-detachment block is fixed to one end of the second support rod to prevent the second roller from slipping during rotation.

[0018] Furthermore, the replacement mechanism includes a fixed rod fixed to one end of the second transmission rod; the fixed rod extends to the outer surfaces on both sides and has a sixth sliding groove; two third sliders are slidably connected inside the sixth sliding groove; a fourth spring is fixedly connected to one side of the outer surface of the two third sliders; a square opening is provided at the center of the blade.

[0020] A method for cutting aluminum alloy cables for installation includes the following steps:

[0021] S1: First, place the cable in the sliding clamping mechanism. The sliding clamping mechanism and the adapting mechanism will limit the cable of different thicknesses. At this time, the cable can only slide axially under the action of the adapting mechanism.

[0022] S2: To cut the cable to the appropriate length, slide the starting point of the cable measurement to the first roller of the adapting mechanism, then press the slide bar to open the push-button switch to activate the length measuring mechanism, and then slide the cable axially. The display screen shows the length of the cable that has been slid over. If the length does not need to be measured, there is no need to press the slide bar.

[0023] S3: When the user slides the sliding switch, the tensioning and fixing mechanism in the cutting mechanism will straighten and fix the cable in the sliding clamping mechanism, and bring the cable and the sliding clamping mechanism close to the blade for cutting. At the same time, the auxiliary sliding mechanism will assist the sliding clamping mechanism in sliding.

[0024] S4: If the user needs to replace the blade, press and hold the two third sliders in the replacement mechanism at the same time to disassemble and replace the blade. When cutting, if the infrared sensor detects that a human body part is close to the blade, the cutting mechanism will stop working.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] (1) By setting up a sliding clamping mechanism and an adaptation mechanism, the present invention can realize the indiscriminate cutting of cables of different thicknesses, thereby increasing the applicability of the device;

[0027] (2) By setting up a length measuring mechanism, the present invention can avoid the waste of cable caused by the cutter visually estimating the length of the cable, and also eliminates the need for the user to use other tools to assist in measuring the length of the cut cable, making the measurement process more convenient and improving the efficiency of the measurement and cutting work.

[0028] (3) By setting up a close-cutting mechanism, an auxiliary sliding mechanism and a tensioning and fixing mechanism, the present invention eliminates the need to constantly replace the mounting base according to the wear of the mounting base. When cutting thicker and harder cables, the cutting can be completed smoothly and the cutting surface is relatively flat. At the same time, the tensioning and fixing mechanism can also straighten and fix the cable section being cut, making cutting convenient. Attached Figure Description

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example 1:

[0044] Please see Figures 1 to 11 A cutting device for laying aluminum alloy cables includes a handle 8, a U-shaped base 1 fixed to one end of the handle 8, and an anti-loss ring 9 fixed to the other end of the handle 8. It also includes...

[0045] The sliding clamping mechanism 2 is located on the lower inner surface of the U-shaped base 1;

[0046] The length measuring mechanism 5 is located inside the sliding clamping mechanism 2 and inside the U-shaped seat 1;

[0047] The approach cutting mechanism 6 is located on the inner surfaces of both sides of the U-shaped base 1; an infrared sensor 7 is located on the inner surface of the U-shaped base 1 at a position away from the approach cutting mechanism 6.

[0048] like Figure 1 and Figure 4As shown, the sliding clamping mechanism 2 includes a first groove 21 extending from the inside of the U-shaped base 1 to the lower inner surface of the U-shaped base 1; a functional rod 23 is slidably connected to the inner surface of the first groove 21 extending to the bottom of the U-shaped base 1; an auxiliary sliding mechanism 4, which is rectangular in shape and extends from the inner surface of the functional rod 23 inside the first groove 21 to the front and rear outer surfaces, slides along the inside of the first groove 21; a first spring 22 is fixedly connected to one inner surface of the first groove 21, and one end of the first spring 22 is fixedly connected to one outer surface of the functional rod 23 inside the first groove 21; the functional rod 23 extends from the inner surface of the first groove 21 to the lower inner surface of the U-shaped base 1. A sliding rod 24 is slidably connected to the upper end of the slide rod 24; a first substrate 25 is fixedly connected to the upper end of the slide rod 24; a second groove 29 is formed on the upper surface of the first substrate 25; a first telescopic rod 26 is fixedly connected to the inner surface of one side of the second groove 29; a clamping plate 27 is fixedly connected to one end of the first telescopic rod 26; an arc-shaped clamping plate 28 is fixedly connected to the upper surface of the first substrate 25 away from the second groove 29; both the clamping plate 27 and the arc-shaped clamping plate 28 are provided with an adaptation mechanism 3 extending to one side of their inner surfaces, and the first substrate 25 is also provided with an adaptation mechanism 3 extending to its upper surface.

[0049] like Figure 5 As shown, the adaptation mechanism 3 includes a roller groove 35 extending to the upper surface inside the first substrate 25 and two third slide grooves 31 inside the first substrate 25; a second spring 32 is fixedly connected to the lower inner surface of each of the two third slide grooves 31; a first slider 33 is fixedly connected to the upper end of each of the two second springs 32; a connecting rod 34 is fixedly connected to one outer surface of each of the two first sliders 33; a first roller 36 is rotatably connected to the outer circular surface of the connecting rod 34.

[0050] like Figure 4 and Figure 6 As shown, the auxiliary sliding mechanism 4 includes roller grooves 41 at the four vertices of the front and rear outer surfaces of the functional rod 23 inside the first slide groove 21; a first support rod 42 is fixedly connected to one side of the inner surface of each of the eight roller grooves 41; and rollers 43 are rotatably connected to the outer circular surfaces of each of the eight first support rods 42.

[0051] To address the limitation of application caused by the inability of the comparative patent to indiscriminately cut cables of different thicknesses, this invention solves this problem by setting up a sliding clamping mechanism 2 and an adaptation mechanism 3. When the cable is placed in the clamping mechanism 2, the first telescopic rod 26 in the first base plate 25 extends and retracts, causing the clamping plate 27 to move towards the arc-shaped clamping plate 28. When the surface of the cable is pressed against each adaptation mechanism 3, since the first slider 33 is fixedly connected to the connecting rod 34, the first slider 33 in each adaptation mechanism 3 can slide inside the third groove 31 under the action of the second spring 32, so that the outer circular surface of the first roller 36 inside the roller groove 35 better fits the surface of the cable. By setting up the sliding clamping mechanism 2 and the adaptation mechanism 3, this invention enables the device to indiscriminately cut cables of different thicknesses, thus increasing the applicability of the device.

[0052] like Figure 3 , Figure 4 and Figure 5 As shown, the length measuring mechanism 5 includes a rotation meter 53 installed on the inner surface of one side of the roller groove 35 and a fourth slide groove 54 extending from the inside of the function rod 23 to the upper outer surface; a push-button switch 56 is fixedly connected to the lower inner surface of the fourth slide groove 54, and a third spring 55 is fixedly connected to the lower inner surface of the fourth slide groove 54 at a position outside the push-button switch 56, and the upper end of the third spring 55 is fixedly connected to the lower outer surface of the slide rod 24; a microcontroller 52 is installed inside the U-shaped base 1 at a position away from the first slide groove 21; a display screen 51 is installed inside the U-shaped base 1 at a position below the microcontroller 52.

[0053] The comparative patent cannot measure the length of the cable to be cut. Traditional cutting devices require users to visually estimate or use other length measuring tools for assistance. Visually estimating the length of the cable can easily lead to waste. Using other length measuring tools to cut the cable is also inconvenient.

[0054] This invention solves this technical problem by setting a length measuring mechanism 5. When the starting point of the cable measurement is located at the first roller 36, the user applies a force between the cable and the first substrate 25, causing the slide bar 24 to slide along the inside of the fourth slide groove 54 under the action of the third spring 55 to open the push-button switch 56. At this time, the microcontroller 52 receives information feedback and controls the rotation meter 53 to start working. The user needs to slide the sliding clamping mechanism 2 along the cable. During the sliding process, the rotation meter 53 starts to calculate the number of rotations of the first roller 36. The length of the cable that has been slid through is calculated by the number of rotations of the first roller 36, and finally the length is displayed on the display screen 51.

[0055] By setting up a length measuring mechanism 5, this invention can avoid the waste of cable caused by the cutter visually estimating the length of the cable, and also eliminates the need for the user to use other tools to assist in measuring the length of the cut cable, making the measurement process more convenient and improving the efficiency of the measurement and cutting work.

[0056] like Figure 2 and Figure 7 As shown, the close-cutting mechanism 6 includes two second telescopic rods 61 fixed to the inner surface of one side of the U-shaped base 1 and a motor base 68 fixed to the inner surface of the other side of the U-shaped base 1; one end of each of the two second telescopic rods 61 is fixed to a tension fixing mechanism 62; the interior of the motor base 68 extends to one side of its outer surface and has a motor groove 66; a second motor 67 is fixed to one side of the inner surface of the motor groove 66; a second transmission rod 65 is fixed to the output end of the second motor 67; a replacement mechanism 64 is fixed to one end of the second transmission rod 65; a blade 63 is slidably connected to the outer surface of the replacement mechanism 64; a sliding switch 69 is slidably connected to the rounded corner of one side of the outer surface of the U-shaped base 1.

[0057] like Figure 8 As shown, the tensioning and fixing mechanism 62 includes a second base plate 621 fixedly connected to one end of the second telescopic rod 61; a fifth sliding groove 622 is formed on the inner surface of the second base plate 621 extending to one side; a third telescopic rod 623 is fixedly connected to the inner bottom of the fifth sliding groove 622; a second slider 624 is fixedly connected to the upper end of the third telescopic rod 623; a first motor 625 is fixedly connected to the inside of the second slider 624; a first transmission rod 626 is fixedly connected to the output end of the first motor 625; a rotating rod 627 is fixedly connected to one end of the first transmission rod 626; a second support rod 628 is fixedly connected to one side of the outer surface of the second base plate 621; a second roller 629 is rotatably connected to the outer circular surface of the second support rod 628, and an anti-detachment block is fixedly connected to one end of the second support rod 628 to prevent the second roller 629 from slipping during rotation.

[0058] The cutting method using a close-range cutter head in the comparative patent is problematic because the cutter head can easily damage the mounting base, requiring frequent disassembly and replacement based on the wear of the mounting base. When cutting thicker and stiffer cables, the close-range cutter head of the telescopic rod can easily cause the cut to be stuck or the cut surface to be incomplete. Furthermore, the components that are meant to straighten the cable section cannot be straightened. If the cable section is twisted, it can easily lead to cutting errors.

[0059] This invention solves this technical problem by setting up a close-cutting mechanism 6, an auxiliary sliding mechanism 4, and a tensioning and fixing mechanism 62. When the sliding switch 69 is slid open, the second telescopic rod 61, which is fixed to the U-shaped seat 1, extends, and the third telescopic rod 623 inside the fifth slide groove 622 extends and retracts. The first motor 625 inside the two second sliders 624 drives the rotating rod 627 to rotate in different directions, which, together with the rolling second roller 629, straightens and fixes the cable in the sliding clamping mechanism 2. During the close-cutting process of the second telescopic rod 62, the roller 43 in the auxiliary sliding mechanism 4 slides inside the first slide groove 21, which together drives the cable to slide close to the rotating blade 63. The second motor 67 drives the rotating blade 63 to complete the cutting task. During the sliding process, the functional rod 23 located inside the first slide groove 21 slides inside the first slide groove 21 under the action of the first spring 22.

[0060] This invention eliminates the need to constantly replace the mounting base based on its wear level by setting up a close-to-cutting mechanism 6, an auxiliary sliding mechanism 4, and a tensioning and fixing mechanism 62. It also allows for smooth cutting of thicker and stiffer cables while ensuring a relatively flat cut surface. At the same time, the tensioning and fixing mechanism 62 can straighten and fix the cut section of cable, making cutting easier.

[0061] like Figure 9 and Figure 11 As shown, the replacement mechanism 64 includes a fixed rod 641 fixed to one end of the second transmission rod 65; the fixed rod 641 extends to the outer surfaces on both sides and has a sixth sliding groove 642; the sixth sliding groove 642 is slidably connected to two third sliders 644; a fourth spring 643 is fixedly connected to one side of the outer surface of the two third sliders 644; a square opening 645 is opened at the center of the blade 63.

[0062] like Figure 10 As shown, the fixing rod 641 is a cuboid design, which, together with the square opening 645 on the blade 63, serves to fix and limit the blade 63 during high-speed rotation.

[0063] The present invention provides a replacement mechanism 64 to switch worn blades 63. When installing or removing blades 63, the user presses down on two third sliders 644 at the same time. Under the action of the fourth spring 643, the third sliders 644 can be returned to their original positions after the blades 63 are replaced, thus playing a limiting role. The fixed rod 641 adopts a cuboid design, which can effectively drive the blades 63 on the fixed rod 641 to rotate via the second transmission rod 65.

[0064] A cutting method for laying aluminum alloy cables, such as Figure 12 As shown, it includes the following steps:

[0065] S1: First, place the cable in the sliding clamping mechanism 2. The sliding clamping mechanism 2 and the adapting mechanism 3 will limit the cable of different thicknesses. At this time, the cable can only slide axially under the action of the adapting mechanism 3.

[0066] S2: If you want to cut the cable to the corresponding length, you need to slide the starting point of the cable measurement to the first roller 36 of the adaptation mechanism 3, then press the slide bar 24 to open the push switch 56 to activate the length measuring mechanism 5, and then slide the cable axially. The display screen 51 shows the length of the cable that has been slid. If you do not need to measure the length, you do not need to press the slide bar 24.

[0067] S3: When the user slides the sliding switch 69, the tensioning and fixing mechanism 62 in the cutting mechanism 6 will straighten and fix the cable in the sliding clamping mechanism 2, and bring the cable together with the sliding clamping mechanism 2 close to the blade 63 for cutting. At the same time, the auxiliary sliding mechanism 4 will assist the sliding of the sliding clamping mechanism 2.

[0068] S4: If the user needs to replace the blade 63, press and hold the two third sliders 644 in the replacement mechanism 64 at the same time to disassemble and replace the blade 63. When cutting, if the infrared sensor 7 detects that a human body part is close to the blade 63, the cutting mechanism 6 will stop working.

[0069] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
