Furthermore, the high temperatures of the metallurgical equipment during operation can also affect the cables. To address these problems and shortcomings, a protective device for the external power cables of metallurgical equipment is urgently needed. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide a protective device for external wires of metallurgical equipment. This addresses the limitations of existing metallurgical equipment, which typically uses external wires during operation. These external wires can wear down over time, and the metal outer wall of the metallurgical equipment may also damage the external wires. Furthermore, the high temperature of the metallurgical equipment itself during operation can also affect the external wires.

[0026] like Figure 1 , Figure 2 and Figure 4As shown, an embodiment of this utility model provides a protective device for external electrical wires of metallurgical equipment, including: a protective box 1 and a protective box 2; a positioning pin 101 is fixedly mounted on the bottom of the protective box 1, a circular hole 102 is opened on the top of the protective box 1, a fixing ring 103 is fixedly mounted on the inner wall of the circular hole 102, a spring 104 providing elastic force is fixedly mounted on the top of the fixing ring 103, a moving shaft 105 is fixedly mounted on the top of the spring 104, the moving shaft 105 passes through the fixing ring 103, and a fixing shaft 106 is fixedly mounted on the bottom end of the moving shaft 105; a ball bearing 107 for locking and fixing is abutted against the outer wall of the fixing shaft 106, and the ball bearing 107... A circumferential groove 108 is provided on the outer wall of the fixed shaft 106 through the positioning pin 101; a circular groove 201 is provided on the top of the second protective box 2, and a positioning groove 202 is provided on the inner wall of the circular groove 201. The outer wall of the ball 107 is engaged with the inner wall of the positioning groove 202. A sliding groove 109 is provided on the bottom of the first protective box 1, and a sliding rod 203 is slidably connected to the inner wall of the sliding groove 109. The bottom end of the sliding rod 203 is fixedly connected to the top of the second protective box 2. By setting the sliding groove 109 and the sliding rod 203, it is convenient to connect the first protective box 1 and the second protective box 2 when the fixation of the first protective box 1 and the second protective box 2 is released, thereby improving the convenience of the staff in installing the device.

[0027] like Figure 2 and Figure 4 As shown, the top of the protective box 1 is provided with a guide groove 110, which corresponds to the position of the round hole 102. By setting the guide groove 110, it is easier for the staff to press the moving shaft 105, thereby improving the convenience of the device during use.

[0028] like Figure 1 and Figure 3 As shown, the top of the protective box 1 has a groove 111, and the inner wall of the groove 111 is fixedly fitted with a heat insulation plate 112. By setting the groove 111 and the heat insulation plate 112, it is beneficial to reduce the impact of the high temperature generated during the operation of metallurgical equipment on the external wires, thereby ensuring the normal use of the external wires.

[0029] like Figure 3 As shown, the bottom of the protective box 1 has a retention groove 113, and the inner wall of the retention groove 113 is fixedly fitted with a protective pad 114. By setting the retention groove 113 and the protective pad 114, it is beneficial to protect the outer wall of the external wire, thereby improving its stability during use.

[0030] like Figure 2 and Figure 4 As shown, the cross-sectional shape of the annular groove 108 is an isosceles trapezoid, and the depth of the annular groove 108 is adapted to the diameter of the ball 107. By limiting the annular groove 108, it is beneficial to guide the ball 107.

These four sets of positioning pins 101, fixing rings 103, springs 104, moving shafts 105, fixing shafts 106, and ball bearings 107 are evenly distributed at the four corners of the protective box 1. By limiting the number and position of the positioning pins 101, fixing rings 103, springs 104, moving shafts 105, fixing shafts 106, and ball bearings 107, it is beneficial to improve the stability and firmness of the connection between the protective box 1 and the protective box 2.

[0032] The technical solution provided by this utility model, during operation, pushes the fixed shaft 106 towards the positioning pin 101 by pressing the movable shaft 105. When the end of the fixed shaft 106 abuts against the inner wall of the positioning pin 101, the position of the ball 107 parallel to the annular groove 108, and the ball 107 rolls into the annular groove 108. Then, the fixed shaft 106 is released, and the movable shaft 105 is pushed away from the fixed ring 103 by the spring 104, thereby pulling the fixed shaft 106 away from the positioning pin 101. At this time, the ball 107 separates from the positioning groove 202, and the protective box 1 and the protective box 2 can be separated. The external wire can then be passed between the protective box 1 and the protective box 2. Repeating the above steps will connect and fix the protective box 1 and the protective box 2, thus achieving protection for the external wire.

[0033] By setting the sliding groove 109 and the sliding rod 203, it is convenient to connect the protective box 1 and the protective box 2 when the fixing of the protective box 1 and the protective box 2 is released, thereby improving the convenience of the staff to install the device.

[0034] By setting the groove 111 and the heat insulation plate 112, it is beneficial to reduce the impact of the high temperature generated during the operation of metallurgical equipment on the external wires, thereby ensuring the normal use of the external wires.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
