Technical Field

[0001] This utility model relates to the field of power construction, specifically to a cable insulation trimming device for power construction. Background Technology

[0002] Electrical engineering refers to engineering related to the production, transmission, and distribution of electrical energy. In a broader sense, it also includes engineering that uses electricity as a power source and energy source in various fields, and can be understood as power transmission and transformation expansion projects.

[0003] In existing technology, during the process of electrical construction, workers usually need to connect two cables. In the process of connecting two cables, the insulation layer of the cable to be connected needs to be peeled off. If it is a thin wire, workers can burn the insulation layer with a lighter. However, for thicker cables, workers will burn the copper wires inside when burning the insulation layer. If the insulation layer is peeled off with scissors, it is not only cumbersome, time-consuming and labor-intensive, but also difficult to control the force, which may easily cut the conductors inside the cable, thus rendering a section of cable unusable and reducing its practicality.

[0004] Therefore, it is necessary to provide a cable insulation trimming device for power construction to solve the above-mentioned technical problems. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] A cable insulation trimming device for power construction includes an arc plate 2, and further includes a rotating component 1, a clamping component 3, a handle 4, and a trimming component 5. The handle 4 is fixedly connected to one side of the arc plate 2. The clamping component 3, which limits the cable 6, is connected to the arc plate 2. The rotating component 1, which rotates the trimming component 5, is connected to the arc plate 2.

[0030] The rotating assembly 1 includes two motors 11, which are fixedly connected to both ends of the curved plate 2. The output shafts of the two motors 11 pass through the curved plate 2, and the ends of the output shafts of the two motors 11 are fixedly connected to the center of the corresponding gear 12. The two gears 12 mesh with the arc-shaped rack 13, and the arc-shaped rack 13 meshes with the corresponding gear 2 14. The central axes of the two gears 2 14 are movably connected to the curved plate 2. The arc-shaped rack 13 is provided with a sliding groove 15, which slidably connects to the curved plate 2. The arc-shaped rack 13 can rotate around the central axis of the curved plate 2.

[0031] The trimming assembly 5 includes a square tube 53, which is fixedly connected to the arc-shaped rack 13. The square tube 53 is slidably connected to a guide rod 54. One end of the guide rod 54 is fixedly connected to a trimming tip 55, and the other end of the guide rod 54 is movably connected to one end of a lead screw 52. The lead screw 52 is threadedly connected to the square tube 53, and the other end of the lead screw 52 is fixedly connected to the center of a knob 51. One side of the square tube 53 is threadedly connected to a set screw 56.

[0032] The clamping assembly 3 includes a lead screw groove 31, which is fixedly connected to the arc plate 2. Two sliders 33 are provided in the lead screw groove 31, and the two sliders 33 are respectively fixedly connected to the corresponding clamping plates 32. The two ends of the inner side of the lead screw groove 31 are respectively movably connected to one end of a bidirectional lead screw 34. The bidirectional lead screw 34 is provided with two sections of threads with opposite directions, and the bidirectional lead screw 34 is respectively threaded to the corresponding sliders 33.

[0033] One end of the bidirectional lead screw 34 passes through one side of the lead screw groove 31. One end of the bidirectional lead screw 34 is fixedly connected to the end of the central shaft of one end of the worm gear 37. The two central shafts of the worm gear 37 are respectively movably connected to the two sides of the housing 38. The housing 38 is fixedly connected to the lead screw groove 31.

[0034] The worm gear 37 meshes with the worm 35, and the central shafts at both ends of the worm 35 are movably connected to both sides of the housing 38.

[0035] The end of the central shaft of the worm gear 35 is fixedly connected to the center of the knob 36.

[0036] The wiring diagram of the motor 11 in this utility model is common knowledge in the field, and its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the motor 11 will not be explained in detail.

[0037] The working principle is as follows: First, hold the handle 4 to pick up the device and place the cable 6 to be trimmed between the two clamps 32. Turn the knob 36. The knob 36 rotates through the worm gear 35 meshing with the worm wheel 37. The worm wheel 37 drives the double-acting screw 34 to rotate. The double-acting screw 34 drives the slider 33 to slide. The two sliders 33 respectively drive the clamps 32 to limit the cable 6. At this time, stop turning the knob 36. There is a self-locking structure between the worm wheel 37 and the worm gear 35. The worm wheel 37 and the worm gear 35 will not rotate on their own.

[0038] Next, according to the cutting position of cable 6, loosen the set screw 56 and turn the knob 1 51. The knob 1 51 drives the screw rod 52 to rotate, and the screw rod 52 drives the guide rod 54 to move along the square tube 53, so that the guide rod 54 drives the cutting tip 55 to move, so that the cutting tip 55 is inserted into the insulation layer of cable 6, with the insertion depth being the same as the thickness of the insulation layer. At this time, stop turning the knob 1 51 and tighten the set screw 56, so that the set screw 56 abuts against the guide rod 54 to prevent the guide rod 54 from moving in subsequent operations, causing the cutting tip 55 to over-cut the cable 6 and damage the copper wires inside the cable 6.

[0039] Then, start the two motors 11. The two motors 11 drive the corresponding gears 12 to rotate simultaneously in the same direction and at the same speed. The two gears 12 mesh with the arc rack 13 to rotate. The arc rack 13 meshes with the two gears 14 to rotate. The arc rack 13 drives the trimming component 5 to rotate, so that the trimming blade 55 rotates around the cable 6. The trimming blade 55 cuts the insulation layer of the cable in one circle, thus completing the trimming of the insulation layer of the cable 6.

[0040] Compared with related technologies, this utility model has the following beneficial effects: Holding the handle 4, the device is positioned between the two clamping plates 32. The clamping assembly 3 limits the cable 6, and a self-locking structure exists between the worm gear 37 and the worm 35, preventing them from rotating on their own. Based on the cutting position of the cable 6, the trimming assembly 5 inserts the trimming tip 55 into the insulation layer of the cable 6 to the same depth as the insulation layer thickness. The set screw 56 is then tightened to press against the guide rod 54, preventing the guide rod 54 from moving during subsequent operations and causing the trimming tip 55 to over-trim the cable 6, damaging the copper wires inside. By rotating the assembly 1, the trimming tip 55 cuts a circle around the cable's insulation layer, completing the insulation trimming of the cable 6.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
