[0002] Electric rotary drilling rigs are widely used in open-pit mining and other operations. Their operation depends on a stable power supply. As a key component for power transmission, cables are usually laid out by burying them.

[0003] However, traditional cable laying has many safety hazards. The mining environment is complex and the ground is uneven. When mine cars pass through the cable laying passages, the cables are easily pulled and squeezed, causing damage to the cable sheath, short circuits in the internal circuits, and other faults, affecting the service life of the cables and even causing safety accidents. On the other hand, when drilling rigs need to be moved, high-voltage cables need to be laid through passages frequently, increasing maintenance costs and making movement inconvenient. Therefore, it does not meet the existing needs. In response, we have proposed an overhead cable bridge safety device adapted to electric rotary drilling rigs. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1 to 4 As shown, a safety device for an overhead cable bridge adapted to an electric rotary drill includes two bases 1. A support column 8 is detachably mounted on the top of each base 1. Two rope drum hooks 7 are detachably mounted on the outer side of the bottom end of each support column 8. A perforated steel plate 5 is fixed to the top of each support column 8. An adjusting pulley 6 is installed at the bottom of the perforated steel plate 5. An adjusting rope 4 is attached to the outer side of the adjusting pulley 6 and is wound around the outer side of the rope drum hooks 7. A high-voltage cable insulation clamp 2 is detachably mounted on one end of the adjusting rope 4. The high-voltage cable is suspended and supported by the two symmetrically positioned high-voltage cable insulation clamps 2, thus eliminating the need for deep burial of the high-voltage cable, preventing it from being crushed, and reducing the number of operators and excavation equipment required, thereby lowering labor and equipment operating costs.

[0021] The base 1 includes a wooden seat plate, and plastic tires are mounted on both sides of the wooden seat plate via pivots, which facilitates the movement of the base 1 and the device, thereby allowing the device to be moved.

[0022] The upper surface of the high-voltage cable insulation clamp 2 is provided with a cable clamping groove 10. The cable clamping groove 10 has a U-shaped structure and the high-voltage cable is clamped inside the cable clamping groove 10, ensuring that the high-voltage cable insulation clamp 2 moves simultaneously with the high-voltage cable, thereby adjusting the height of the high-voltage cable.

[0023] Two anti-detachment arc-shaped pieces 9 are also installed on the upper surface of the high-voltage cable insulation clamp 2. The two anti-detachment arc-shaped pieces 9 are located on both sides of the cable clamping groove 10. The anti-detachment arc-shaped pieces 9 include adhesive pieces 91. The adhesive pieces 91 are fixed to the high-voltage cable insulation clamp 2 by adhesive. A bending adjustment piece 92 is fixed on one side of the adhesive piece 91, and an anti-detachment limiting piece 93 is fixed on the other side of the bending adjustment piece 92. The anti-detachment arc-shaped pieces 9, composed of adhesive pieces 91, bending adjustment pieces 92, and anti-detachment limiting pieces 93, restrict the position of the high-voltage cable inside the cable clamping groove 10 from above, so as to prevent the high-voltage cable from falling out of the cable clamping groove 10.

[0024] The ends of the adjusting rope 4 and the high-voltage cable insulation clamp 2 are Y-shaped forked. Both ends of the fork of the adjusting rope 4 are fixed with locking cylindrical blocks 3. The locking cylindrical blocks 3 are slidably inserted into the high-voltage cable insulation clamp 2. The ends of the two locking cylindrical blocks 3 that are in contact with each other are fixedly embedded with strong magnets 11. The two strong magnets 11 are magnetically attracted to each other. The high-voltage cable insulation clamp 2 and the adjusting rope 4 are connected by the locking cylindrical blocks 3. The two locking cylindrical blocks 3 are detachable, which makes it easy to remove the high-voltage cable clamped on the high-voltage cable insulation clamp 2.

[0025] Working principle: For suspending and supporting high-voltage cables, firstly, the adjusting rope 4 is attached to the outside of the two adjusting pulleys 6, and the middle part of the adjusting rope 4 is wound around the outside of the rope drum hook 7. Then, the rope drum hook 7, support column 8, and perforated steel plate 5 are erected and fixed to the upper surface of the base 1. Next, the anti-detachment arc-shaped plates 9 on both sides of the cable clamping groove 10 are bent upwards. After the anti-detachment arc-shaped plates 9 are bent, the high-voltage cable is clamped inside the cable clamping groove 10. The anti-detachment arc-shaped plates 9 are then released, allowing them to return to their original shape under the elastic action of the bending adjusting plate 92. The anti-detachment arc-shaped plates 9 then restrict the high-voltage cable from above the cable clamping groove 10. The two high-voltage cable insulation clamps 2 are then inserted into the high-voltage cable insulation clamp 2 by inserting the end of the clamping cylindrical block 3 with the strong magnet 11. The two clamping cylindrical blocks 3 are then attracted and fixed by the strong magnet 11. Finally, by pulling the adjusting rope 4, the high-voltage cable insulation clamp 2 and the high-voltage cable clamped inside the cable clamping groove 10 are moved upward, so that the two high-voltage cable insulation clamps 2 suspend the high-voltage cable. This eliminates the need for deep burial of the high-voltage cable, prevents the high-voltage cable from being crushed, and reduces the number of operators and the use of excavation equipment, thereby reducing labor and equipment operating costs.
