[0011] 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.
[0012] Reference Figures 1-3 This utility model provides an embodiment of a medium-frequency electric furnace water cable protection device, comprising two platforms 1, which serve as the basic load-bearing structure of the device and provide stable support for the entire protection device. Two fixed frames 2 are fixedly connected between the two platforms 1, and the two fixed frames 2 are parallel and symmetrically distributed. An installation roller 3 is installed between the two fixed frames 2. The installation roller 3 can rotate flexibly around its own axis. When the cable extends to the bottom, it can abut against the installation roller 3 to reduce friction when the cable moves. An adjustment mechanism is installed on the top of the platform 1. The adjustment mechanism can flexibly adjust the height and angle of the device to adapt to different usage scenarios. A fixing component is installed on the top of the adjustment mechanism. The fixing component is used to stably fix the cable and prevent it from loosening. An abutment component is installed between the two platforms 1. The abutment component can further limit and fix the cable at the bottom. The adjustment mechanism includes an angle adjustment component and a height adjustment component. The angle adjustment component includes an adjustment disk 4, which is fixedly connected to the top of the platform 1. The adjustment disk 4 has multiple fixing slots 5 inside, which are evenly distributed in a ring around the center of the adjustment disk 4, providing multiple selectable positions for angle fixing. A support cylinder 8 is rotatably connected inside the adjustment disk 4. The support cylinder 8 can rotate inside the adjustment disk 4 to change the angle. A bolt 7 is installed inside the fixing slots 5. The bolt 7 is installed inside the adjustment disk 4 and the support cylinder 8. When the support cylinder 8 rotates to a suitable angle, tightening the bolt 7 will fix the support cylinder 8 to the adjustment disk 4. A rotating rod 6 is fixedly connected to the bottom of the adjustment disk 4. The rotating rod 6 is coaxially arranged with the adjustment disk 4. The support cylinder 8 is rotatably connected to the outside of the rotating rod 6.
[0013] The height adjustment assembly includes a telescopic bar 10, which is slidably connected inside the support cylinder 8. The telescopic bar 10 can slide up and down inside the support cylinder 8 to change the height. Multiple grooves 11 are evenly distributed along the length of the telescopic bar 10, providing multiple height settings. A housing 9 is installed on the outside of the support cylinder 8, and a pin 16 is installed inside the housing 9. The size of the pin 16 matches the grooves 11 and 21. A spring 20 is fixedly connected to one end of the housing 9. The spring 20 is always in a charged state, providing... The pin 16 provides a clamping force. The support cylinder 8 has a second groove 21 inside. The pin 16 is engaged in the groove 11 and the second groove 21, thereby fixing the telescopic strip 10 to the support cylinder 8. The support cylinder 8 has a movable rod 19 fixedly connected to the outside. The movable rod 19 provides a fulcrum for the rotation of the outer shell 9. The outer shell 9 is rotatably connected to one end of the movable rod 19, so that the outer shell 9 can rotate around the movable rod 19, which facilitates the operation of the pin 16. The top of the pin 16 is fixedly connected to a rotating shaft 17. The outer shell 9 has a waist hole 18 inside. The rotating shaft 17 is slidably connected inside the waist hole 18.
[0014] Reference Figure 1 and Figure 5 The abutment assembly includes two abutment blocks 22, which are fixedly connected to the outside of the platform 1. The shape of the abutment blocks 22 is adapted to the outer contour of the cable, so that they can fit the cable better. Both ends of the abutment blocks 22 are fixedly connected to round rods 24, which are perpendicular to the abutment blocks 22. Springs 25 are sleeved on the outside of the two round rods 24. Clamping blocks 23 are slidably connected to the outside of the springs 25. The clamping blocks 23 can slide along the round rods 24. Under the elastic force of the springs 25, the clamping blocks 23 can tightly press the cable onto the abutment blocks 22. One end of the round rods 24 is threadedly connected to a disassembly cap 26. The disassembly cap 26 is set to facilitate the installation and disassembly of the clamping blocks 23 and the springs 25. The disassembly cap 26 is located on the outside of the clamping blocks 23. The disassembly cap 26 can limit the clamping blocks 23 and prevent them from falling off the round rods 24.
[0015] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 The fixing component includes two retaining rings 12, which together form a complete circular structure that fits the shape of the cable. The two retaining rings 12 are rotatably connected by a hinge 15, which allows the two retaining rings 12 to open and close flexibly, facilitating the placement and removal of the cable. One retaining ring 12 is fixedly connected to the top of the telescopic strip 10, and one end of each retaining ring 12 is fixedly connected to a side plate 13. A bolt 2 14 is installed between the two side plates 13. By tightening the bolt 2 14, the two retaining rings 12 can be tightly fixed together, thereby fixing the cable.
[0016] Working principle: First, open bolt 2 14, pass the multi-strand cable through the inside of the retaining ring 12, and then tighten bolt 2 14 to fix the cable and ensure that it will not loosen. Then, press the outer shell 9, the spring 1 20 retracts, and the pin 16 is lifted and disengaged from the groove 2 21 and the groove 1 11. At this time, make appropriate adjustments according to the required height to ensure that the cable does not contact the ground and is more suitable for the connection of the medium frequency furnace. The support cylinder 8 can also be rotated to adjust the cable angle for better connection with other equipment. After adjusting the angle, insert and tighten bolt 1 7.
[0017] Secondly, when the cable extends to the bottom, first make it abut against the installation roller 3, then unscrew the disassembly cap 26, place the cable inside the abutment block 22, then install the clamping block 23, and tighten the disassembly cap 26. At this time, under the action of the second spring 25, the multiple strands of cable are firmly clamped and will not shake. In addition, both the clamping block 23 and the abutment block 22 are made of insulating elastic material, which will not damage the surface of the cable.
