Description

Technical Field

[0001] This invention relates to the field of electrical conduit cutting equipment technology, and in particular to a cable conduit cutting device and its usage method. Background Technology

[0002] The power system, one of the most important achievements in the history of human engineering science, is a power production and consumption system composed of power generation, transmission, transformation, distribution, and consumption. Cables are essential equipment in the power system. When using cables to conduct electricity, they need to be laid within conduits to effectively protect them. Before use, the conduits are cut to appropriate lengths according to work requirements. Furthermore, when using conduits for the second time, the ends are often damaged during the first use, requiring the ends to be cut off. Existing cutting equipment varies depending on the conduit's thickness; thin conduits only require pliers, while thicker conduits require larger cutting equipment. Current methods cut conduits one by one, regardless of thickness, resulting in low work efficiency. Summary of the Invention

[0014] A method of using a cable conduit cutting device, the method comprising the following steps:

[0015] S1. First, start the first electric telescopic rod to raise it, which drives the circular plate, two guide rods and two clamping plates to move upward synchronously. After the clamping plates contact the inverted trapezoidal block, they move upward along the inclined surface of the inverted trapezoidal block. The distance between the two clamping plates increases and the compression spring is compressed.

[0016] S2. Place the multiple cable sleeves to be cut in the arc groove, start the first electric telescopic rod to descend, driving the circular plate, two guide rods and two clamping plates to move downwards synchronously. When the two clamping plates move downwards, they are brought closer to the center by the elastic force of the compression spring and clamp the multiple cable sleeves. At the same time, when the circular plate moves downwards, it squeezes the multiple cable sleeves downwards. When the multiple cable sleeves are clamped by the circular plate and the two clamping plates, stop the first electric telescopic rod.

[0017] S3. Start the cutting mechanism to cut the ends of multiple cable sleeves. After cutting, increase the distance between the two clamps according to step S, then remove the cut multiple cable sleeves, and at the same time start the first electric telescopic rod to return it to its original position.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. In the cable sheath cutting device and its usage method of the present invention, multiple cable sheaths are placed in an arc groove. A first electric telescopic rod drives a clamping plate to move upwards. As the clamping plate moves upwards, it contacts an inverted trapezoidal block, increasing the distance between the two clamping plates and compressing the spring. When the clamping plate moves downwards, it disengages from the inverted trapezoidal block, clamping the left and right sides of the multiple cable sheaths under the elastic force of the spring. Simultaneously, a circular plate presses downwards, clamping and fixing the multiple cable sheaths through the circular plate and clamping plates. After fixing, the ends of the multiple cable sheaths are cut off by a cutting mechanism. Compared to existing technologies, by clamping, fixing, and cutting multiple cable sheaths, the cutting efficiency is higher. Therefore, the present invention has higher cutting efficiency.

[0020] 2. In the cable conduit cutting device and its method of use of the present invention, a second motor drives the guide wheel to rotate, and a third electric telescopic rod is raised to stretch the tension spring. The tension spring drives the mounting plate to move upward, causing the guide wheel to move upward. The cutting line on the guide wheel cuts the end of the cable conduit in one direction. When the cutting line moves above the cable conduit, the end of the cable conduit is completely cut off. Multiple cable conduit ends can be cut at once. By setting the second electric telescopic rod, the distance between the mounting plate and the ends of multiple cable conduits can be controlled, making it convenient to adjust the cutting position of the cable conduit. Therefore, the present invention provides stable cutting and high cutting efficiency.

[0021] 3. In the cable conduit cutting device and its usage method of the present invention, by setting a rotating mechanism, after one end of the cable conduit is cut, the motor can be controlled to rotate, driving the mounting plate, cutting wire, guide wheel and other structures to rotate 180 degrees. Then the cutting wire cuts the other end of the cable conduit from top to bottom, so that the device can automatically cut both ends, eliminating the need to repeatedly handle and fix the cable conduits one by one, thereby effectively improving work efficiency. Therefore, the present invention has high cutting efficiency. Attached Figure Description

[0038] A method of using a cable conduit cutting device, the method comprising the following steps:

[0039] S1. First, start the first electric telescopic rod 3 to rise, which drives the circular plate 4, the two guide rods 34, and the two clamping plates 19 to move upward synchronously. After the clamping plates 19 contact the inverted trapezoidal block 15, they move upward along the inclined surface of the inverted trapezoidal block 15. The distance between the two clamping plates 19 increases, and the compression spring 17 is compressed.

[0040] S2. Place the multiple cable sleeves to be cut into the arc groove 38, start the first electric telescopic rod 3 to descend, and drive the circular plate 4, the two guide rods 34, and the two clamping plates 19 to move downwards simultaneously. When the two clamping plates 19 move downwards, they are brought closer to the center by the elastic force of the compression spring 17 and clamp the multiple cable sleeves. At the same time, when the circular plate 4 moves downwards, it squeezes the multiple cable sleeves downwards. When the multiple cable sleeves are clamped by the circular plate 4 and the two clamping plates 19, stop the first electric telescopic rod 3.

[0041] S3. Start the cutting mechanism to cut the ends of multiple cable sleeves. After cutting, increase the distance between the two clamps 19 according to step S1, then remove the cut multiple cable sleeves, and at the same time start the first electric telescopic rod 3 to return it to its original position.

[0042] The principle of this invention is explained as follows:

[0043] In this invention, the first motor 12, the first electric telescopic rod 3, the second electric telescopic rod 21, the third electric telescopic rod 26, and the second motor 33 are all electrically connected to an external power source.

[0044] First, the first electric telescopic rod 3 is activated to raise the height. Under the drive of the first electric telescopic rod 3, the circular plate 4 slides upward on the connecting rod 13. The two clamping plates 19 move upward synchronously. The first sliding rod 9 slides in the first sliding groove 7. After the two clamping plates 19 contact the inverted trapezoidal block 15, they move upward along the inclined surface of the inverted trapezoidal block 15. At the same time, the two clamping plates 19 move in opposite directions on the two guide rods 34, and the distance between the two clamping plates 19 increases. The compression spring 17 is compressed. When the guide rod 34 moves upward into the through groove 16, the distance between the two clamping plates 19 is at its maximum. Then, multiple cable sleeves are placed in the arc groove 38. Then, the first electric telescopic rod 3 is activated to lower the height. The two clamping plates 19 disengage from the inverted trapezoidal block 15. The compression spring 17 stretches and drives the two clamping plates 19 to move towards each other on the two guide rods 34. The two clamping plates 19 approach each other and clamp the cable sleeves. The circular plate 4 moves downward and squeezes the upper end face of the cable sleeve.

[0045] The second electric telescopic rod 21 is activated, causing the mounting plate 27 to move. When the cutting line 30 is directly below the end of the cable sleeve, the second electric telescopic rod 21 is stopped, and the second motor 33 is activated simultaneously. The guide wheel 28 rotates, causing the cutting line 30 wound on one guide wheel 28 to wind onto the other guide wheel 28. At the same time, the third electric telescopic rod 26 is activated to extend, and the tension spring 24 is stretched, causing the mounting plate 27 to move upward. The T-block 36 of the moving plate 37 slides in the T-groove 35. When the T-block 36 slides to the bottom of the T-groove 35, the moving plate 37 causes the second electric telescopic rod 21 to slide upward in the second slide groove 22, and the cutting line 30 cuts the cable... After the end of the cable sleeve is cut off, the second motor 33 and the third electric telescopic rod 26 are stopped. Then the first motor 12 is started. The second ring 10 rotates under the drive of the first motor 12. The first slide rod 9 drives the cylinder 6 and the first ring 5 to rotate synchronously. After rotating 180 degrees, the mounting plate 27 rotates to the other end of the cable sleeve. The cutting line 30 is located above the other end of the cable sleeve. Then the second motor 33 and the second electric telescopic rod 27 are started in reverse. The mounting plate 27 moves downward. The cutting line 30 cuts the other end of the cable sleeve from top to bottom. After cutting, the second motor 33 and the second electric telescopic rod 27 are stopped, and the cutting of the cable sleeve is completed.
