[0037] Example

[0038] Reference Figure 1-10 A cable drag protection device is used to protect the cable of a walking device during the walking process, comprising:

[0039] An annular groove 1, the annular groove 1 is an annular structure with a non-closed structure, and the annular groove 1 is extended along an arc; a drag chain 2, the drag chain 2 is used for passing cables and / or pipes, the fixed end of the drag chain 2 is connected to the side wall of one end of the annular groove 1, the free end of the drag chain 2 is extended along the annular groove 1, and can be bent horizontally in the annular groove 1 and extend toward the fixed end; a rolling guide mechanism 7, the rolling guide mechanism 7 is connected and arranged at the bottom of the annular groove 1, and extends radially along the annular groove 1, and the rolling guide mechanism 7 is designed in sections in the radial direction of the annular groove 1, so as to be used for freely rolling and guiding the drag chain 2 respectively.

[0040] The above technical solution can effectively protect the wires through the drag chain 2 and the annular groove 1, and can also prevent interference to furnace workers after being suspended in the air. The rolling guide mechanism 7 can minimize the friction resistance of the drag chain 2 during operation.

[0041] Reference Figure 1-6 The rolling guide mechanism 7 includes a plurality of rolling assemblies, which are evenly and spacedly distributed along the extension direction of the annular groove 1. The rolling assembly includes two rollers connected end to end.

[0042] The above technical solution can reduce resistance by arranging multiple rolling components when the drag chain 2 moves.

[0043] Reference Figure 2-6 The rolling assembly also includes a connecting pipe 10, which is arranged between the two rollers of the rolling assembly. The two ends of the connecting pipe 10 are threaded structures with opposite rotation directions, which are used to connect with the rotating shafts of the two rollers.

[0044] In the above technical solution, the first roller 9 and the second roller 11 can rotate through the connecting pipe 10.

[0045] Reference Figure 1 The fixed end is fixedly connected to the outer wall of the annular groove 1, the roller in the rolling assembly close to the outer wall of the annular groove 1 has a first length, and the roller in the rolling assembly close to the inner wall of the annular groove 1 has a second length, and the second length is greater than the first length.

[0046] In the above technical solution, the stability of the annular groove 1 can be improved by the bracket 4, and the length of the first roller 9 is greater than the length of the second roller 11, which can facilitate the movement of the drag chain 2.

[0047] Reference Figure 6 The rolling assembly also includes a fixing frame 8 and a stop plate. The two fixing frames 8 are respectively arranged on both sides of the annular groove 1 and are used to connect the ends of the two rollers respectively. The stop plate is connected between the pipe 10 and the bottom surface of the annular groove 1.

[0048] In the above technical solution, the stop plate is used to clamp the pipe 10 to prevent it from loosening.

[0049] Reference Figure 5 The annular groove 1 includes multiple groove bodies, and each two groove bodies are connected by a flange 5 and a fastener.

[0050] The above technical solution can facilitate the connection and installation of multiple annular grooves 1 through the flange 5, and the annular groove 1 can be split into multiple parts to reduce the transportation volume and reduce the difficulty of installation.

[0051] Reference Figure 7 The material of the drag chain 2 is engineering plastic or alloy, thereby reducing the weight of the drag chain; the two rollers connected end to end are the first roller 9 and the second roller 11; the outer wall of the annular groove 1 is fixedly connected with multiple brackets 4.

[0052] In the above technical solution, the drag chain 2 is made of engineering plastics or lightweight alloy materials to reduce the weight as much as possible while ensuring its strength. The drag chain 2 adopts a covering structure to protect the pipelines therein.

[0053] like Figure 8-10As shown, one side of the annular groove 1 is fixedly connected to the box body 6, and the bottom of the box body 6 is fixedly connected to the cover body 13. A revolving door 15 is provided on one side of the cover body 13. A rewinding port 24 is opened on one side of the box body 6 and one side of the annular groove 1 and is communicated with. The top inner wall and the bottom inner wall of the box body 6 are rotatably connected to the same rewinding roller 22, and a connecting belt 23 is fixedly provided on one side of the rewinding roller 22. One end of the connecting belt 23 is fixedly connected to the fixed end of the drag chain 2. The bottom inner wall of the cover body 13 is fixedly connected to the motor 3 that drives the rewinding roller 22 to rotate. The output end of the motor 3 passes through the bottom of the box body 6 and is fixedly connected to the bottom end of the rewinding roller 22. One side of the cover body 13 is fixedly provided with two hinges 14 that are convenient for rotating the revolving door 15. One side of the two hinges 14 is fixedly connected to one side of the revolving door 15. A heat dissipation hole 18 is opened on one side of the revolving door 15 for dissipating heat from the motor 3. A filter screen 16 for filtering dust is fixed to one side of the revolving door 15 by screws.

[0054] In the above technical solution, when the drag chain 2 is not in use, the motor 3 is started, and the rotation of the output end of the motor 3 drives the rotation of the winding roller 22, and the rotation of the winding roller 22 drives the movement of the connecting belt 23, and the movement of the connecting belt 23 drives the movement of the fixed end of the drag chain 2, so that the drag chain 2 can be wound up and stored in the box 6 to protect the drag chain 2 and extend its service life. The length of the drag chain 2 can also be placed according to the actual length of the annular groove 1. The motor 3 is a conical rotor motor, and the conical rotor motor will self-lock when the power is off, and the output end will not rotate. Since the heat dissipation holes 18 are provided, the heat dissipation holes 18 can facilitate the motor 3 to dissipate heat, and the filter 16 can filter and intercept dust in the air.

[0055] Reference Figure 9 A T-shaped block 17 is fixedly provided on one side of the revolving door 15, and a concave plate 19 is fixedly provided on one side of the cover body 13. A bolt 20 is threadedly connected to the concave plate 19, and one end of the bolt 20 is welded with a twist bar 21 for facilitating the rotation of the bolt 20. One end of the T-shaped block 17 is inserted into the concave plate 19.

[0056] In the above technical solution, the revolving door 15 is rotated by the hinge 14, and the revolving door 15 drives the T-block 17 to rotate. Then, one end of the T-block 17 is inserted into the concave plate 19, and the twist bar 21 is rotated. The rotation of the twist bar 21 drives the rotation of the bolt 20, so that one end of the bolt 20 is against the inserted end of the T-block 17, thereby fixing the T-block 17.

[0057] Reference Figure 1-10 A walking device includes: an industrial silicon furnace machine, a curved track and the cable drag protection device mentioned above. The industrial silicon furnace machine walks on the curved track, and the drag chain 2 is set on the cables and pipes of the industrial silicon furnace machine.

[0058] The technical effects of the above-mentioned technical solutions, such as the cable drag protection device, are not described in detail here.

[0059] The working principle and use process of this technical solution are as follows: the annular groove 1 is placed around the electric arc furnace, and can be suspended in the air or placed on the ground, depending on the spraying situation of the electric arc furnace. Due to the provision of a drag chain 2, the cables and pipes are passed through the drag chain 2, which solves the problem that the traditional hanging pipelines lack protection and interfere with the workers in front of the furnace after being suspended in the air. The flange 5 can facilitate the connection and installation of multiple annular grooves 1, and the annular groove 1 can be split into multiple parts to reduce the transportation volume and reduce the difficulty of installation. Since a stop plate is provided, the stop plate is used to clamp the pipe 10 to prevent loosening, and since the bottom of the stop plate is connected to the pipe 10 and the top of the stop plate is connected to the bottom surface of the annular groove 1, the overall strength of the rolling assembly can be effectively enhanced. The drag chain 2 is made of engineering plastics or lightweight alloys to reduce the weight as much as possible while ensuring its strength. The drag chain 2 adopts a covering structure to protect the pipelines therein. The side friction can be reduced by the rotating roller 12, and the movement is smoother. The drag chain 2 is placed vertically, which not only facilitates its reciprocating contraction, but also further reduces the friction between the drag chain 2 and the annular groove 1.

[0060] The fixed end of the drag chain 2 is fixed on the annular groove 1, and the other end is connected to the furnace discharge equipment. As the furnace discharge equipment moves, the drag chain 2 will slide on the annular groove 1. When the drag chain 2 moves, the drag chain 2 on the fixed end side of the drag chain 2 moves simultaneously along the axial direction of the first roller 9 and the movement direction of the drag chain 2, while the moving end of the drag chain 2 is in the same direction as the overall movement of the drag chain 2, causing the second roller 11 to rotate in the opposite direction. Therefore, the traditional single roller cannot effectively reduce the friction resistance of the drag chain 2 during movement, that is, when the moving end of the drag chain 2 moves in the direction toward the fixed end, the moving end rubs against the second roller 11 to cause the second roller 11 to rotate in the opposite direction. Since the two rollers of the rolling assembly can roll freely respectively, the friction between the drag chain 2 and the annular groove 1 is greatly reduced.

[0061] The first roller 9, the connecting pipe 10 and the second roller 11 can minimize the friction resistance of the drag chain 2 during operation. When the drag chain 2 is not in use, the motor 3 is started, and the rotation of the output end of the motor 3 drives the rotation of the winding roller 22. The rotation of the winding roller 22 drives the movement of the connecting belt 23. The movement of the connecting belt 23 drives the movement of the fixed end of the drag chain 2. The drag chain 2 can be wound and put into the box 6 to protect the drag chain 2 and extend its service life. The length of the drag chain 2 can also be placed according to the actual length of the annular groove 1. The motor 3 is a conical rotor motor. When the conical rotor motor is powered off, it will self-lock and the output end will not rotate. Heat dissipation holes 18 are provided, through which the motor 3 can dissipate heat, and the filter 16 can filter and intercept dust in the air. When the motor 3 needs to be maintained, since the revolving door 15 is in an openable mode, the motor 3 can be easily maintained. After maintenance, the revolving door 15 is closed, and the revolving door 15 is rotated by the hinge 14. When the revolving door 15 is rotated, the T-block 17 is driven to rotate. Then, one end of the T-block 17 is inserted into the concave plate 19, and the twist bar 21 is rotated. The rotation of the twist bar 21 drives the rotation of the bolt 20, so that one end of the bolt 20 is against the inserted end of the T-block 17, thereby fixing the T-block 17.

[0062] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. The embodiments of the present invention and the features therein can be combined with each other unless there is a conflict. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
