[0024] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.
[0025] like Figures 1-3 The cable outer sheath trimming device shown includes a frame. A lower mold assembly is fixedly mounted in the middle of the frame, and an upper mold assembly is mounted on the top of the frame, which is movable under the drive of a lifting mechanism 14. The lower mold assembly includes a lower support plate 6, a lower heating plate 7, and a lower mold 8 arranged sequentially from bottom to top. The upper surface of the lower mold 8 has lower grooves 9 of different diameters. The upper mold assembly includes an upper support plate 10, an upper heating plate 11, and an upper mold 12 arranged sequentially from top to bottom. The lower surface of the upper mold 12 has upper grooves 13 corresponding to the lower grooves 9. The lower grooves 9 and upper grooves 13 are both semi-circular and arranged sequentially on the lower mold 8 and upper mold 12 according to their diameters. Figure 4 As shown, the lower heating plate 7 and the upper heating plate 11 have a first groove 18 on their inner sides, and a heat-conducting plate 19 is embedded in the first groove 18. The lower heating plate 7 and the upper heating plate 11 have two mounting holes 22 on their sides, and heating tubes 23 are installed in the mounting holes 22. The mounting holes 22 are connected to the first groove 18, and the heat-conducting plate 19 is heated by the heating tubes 23, accelerating the diffusion of heat on the heating plate and improving heating efficiency. The heat-conducting plate 19 is made of copper or aluminum alloy.
[0026] When the cable outer sheath repair device repairs the cable outer sheath, the upper mold assembly is automatically raised by the lifting mechanism 14. After pre-treating the cable damage area, it is placed in the corresponding upper groove 13 and lower groove 9. The upper mold assembly is then lowered by the lifting mechanism 14, causing the upper groove 13 and lower groove 9 to press the cable tightly. The heating tube 23 heats the damaged area, applying pressure and heat to vulcanize and repair the outer sheath damage. The repair process is simple, convenient, and highly efficient. During pre-treatment, the cable damage area is filled with rubber filler strips and then wrapped with rubber repair tape.
[0027] In addition, the lower heating plate 7 and the upper heating plate 11 are connected to the heat-conducting plate 19 through the heating tube 23, which realizes the rapid diffusion of heat and improves working efficiency.
[0028] like Figure 6 As shown, the bottom of the first groove 18 is provided with a third groove 31, which is smaller than the first groove 18. The mounting hole 22 is in communication with the side wall of the third groove 31, and the heating tube 23 is located in the third groove 31.
[0029] like Figure 5As shown, as a further optimization, the outer surfaces of the lower heating plate 7 and the upper heating plate 11 are provided with a second groove 20, and a heat insulation plate 21 is embedded in the second groove 20. By providing a heat insulation plate 21 on the back of the lower heating plate 7 and the upper heating plate 11, heat diffusion can be blocked, energy waste can be reduced, and electricity can be saved.
[0030] The lower mold 8 and the upper mold 12 have detection holes 24 on their sides. The inner end of the detection hole 24 is located at the center of the lower mold 8 and the upper mold 12, and a temperature sensor is installed at the inner end of the detection hole 24. The temperature sensor is used to detect the temperature of the lower mold 8 and the upper mold 12 to ensure that the temperature is maintained at a preset temperature, which facilitates the control of the repair time at the damaged part of the cable.
[0031] The frame includes a rectangular base frame 1 at the bottom and a rectangular placement frame 3 in the middle. The base frame 1 and the placement frame 3 are connected together by four columns 2. A support column 4 is also vertically fixed to the middle of one side of the base frame 1, and the middle of the support column 4 is fixed to the middle of the side of the placement frame 3. A mounting frame 5 is horizontally fixed to the upper end of the support column 4 facing inward. The lifting mechanism 14 is provided on the mounting frame 5. The lower mold assembly is set on the placement frame 3, and the upper mold assembly is connected to the lifting rod 15 of the lifting mechanism 14. Specifically, the lifting mechanism 14 is a lifting cylinder vertically set above the mounting frame 5, and the lifting rod 15 is the cylinder rod of the lifting cylinder. A guide rod 16 is vertically fixed on each side of the lifting rod 15 on the upper support plate 10, and the mounting frame 5 has guide holes corresponding to the guide rods 16.
[0032] The upper support plate 10, the upper heating plate 11, and the upper mold 12 are fixedly connected by bolt assemblies; a first mounting plate 17 is fixedly provided on the placement frame 3, and the first mounting plate 17, the lower support plate 6, the lower heating plate 7, and the lower mold 8 are fixedly connected by bolt assemblies.
[0033] In one embodiment of this utility model, the support column 4 is a square tube. The bottom, middle, and upper inner sides of the support column 4 are respectively provided with a first through hole 25, a second through hole 26, and an elongated clearance hole 27. The heating pipe 23 and temperature sensor wiring in the lower mold assembly enter the support column 4 through the second through hole 26 and exit through the first through hole 25. The heating pipe 23 and temperature sensor wiring in the upper mold assembly enter the support column 4 through the clearance hole 27 and exit through the first through hole 25. The lifting cylinder's piping enters the support column 4 from the top and exits through the first through hole 25. The support column 4 has an open top and the first through hole 25, second through hole 26, and clearance hole 27 on its side, reducing exposed piping and wiring and improving equipment safety.
[0034] An operating table 30 is horizontally fixed on the side of the placement frame 3 away from the support column 4, and cables are placed on the operating table 30 for pretreatment.
[0035] A second mounting plate 28 is fixed on the base frame 1. A control cabinet 29 is mounted on the second mounting plate 28. An air pump and a controller are installed inside the control cabinet 29. Pipes and lines passing through the first through hole 25 are connected to the air pump and the controller, respectively. The air pump is connected to the lifting cylinder pipeline, and a solenoid valve is installed on the pipeline. The solenoid valve is linearly connected to the controller. An electric control button is installed on the operating panel 30. The electric control button is linearly connected to the controller and is used to control the extension and retraction of the lifting cylinder.
[0036] The control cabinet 29 is also equipped with a touch screen display for displaying the temperatures of the two temperature sensors. The temperature of the heating plate can be set through the touch screen display. When the set temperature is reached, the heating tube 23 stops heating. When the temperature is lower than the set temperature, the heating tube 23 heats up to keep the temperature of the heating plate at the set temperature, which is beneficial for the vulcanization treatment of the cable and makes it easier to control the vulcanization time.
[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
