[0002] In coal mine engineering, the power bridge device is an important part of the power system, and undertakes the key task of supporting, protecting and managing the power cable. With the continuous progress of coal mining technology and the increasing demand for electricity, the performance requirements of the power bridge device are also getting higher and higher. However, the traditional power bridge device has some deficiencies in design, especially in the fixed limiting of the cable, which often fails to meet the actual needs of modern coal mine engineering.

[0003] The traditional power bridge device mostly adopts simple hooks, clips or bolts for fixing, which can fix the cable to some extent, but has many drawbacks. For example, hooks and clips are prone to deformation or loosening due to long-term stress, resulting in unstable cable fixation, and even may cause safety accidents. While the bolt fixing method is relatively stable, the installation and disassembly process is cumbersome, which not only increases the construction difficulty, but also reduces the work efficiency.

[0004] In addition, the traditional power bridge device also has obvious deficiencies in the limiting of the cable. Due to the variety and quantity of cables in coal mine engineering, and the need for complex laying and connection inside the bridge, the limiting of the cable is extremely high. However, the traditional bridge device often lacks effective limiting mechanism, resulting in problems such as misalignment, crossing or lifting of the cable during laying, which not only affects the appearance and neatness of the cable, but also may pose a potential threat to the normal operation of the cable.

[0008] Preferably, a strip-shaped groove is formed in the interior of the groove block.

[0009] Preferably, the limiting mechanism comprises: a supporting block arranged between the two supporting rods; a rotating rod threadedly connected at the center of the interior of the supporting block; a top block rotatably arranged at the bottom end of the rotating rod; and a rubber strip fixedly arranged at the bottom end of the top block, wherein the rotating rod is moved up and down in the interior of the supporting block and drives the top block to move up and down simultaneously when the rotating rod rotates, thereby achieving the extrusion and fixation of the cable.

[0010] Preferably, a threaded through hole is formed at the center of the supporting block, and a thread is formed on the outer wall of the rotating rod.

[0011] Preferably, the top block is in an arc-shaped structure.

[0012] Compared with the prior art, the coal mine engineering power bridge device has the following beneficial effects: when the device is used, the groove block, the plug block, the screw rod, the threaded block, the vertical rod and the supporting rod are used in cooperation to achieve the installation and fixation of the limiting mechanism, the supporting block, the rotating rod, the top block and the rubber strip are used in cooperation to achieve the fixation of the cable laid in the interior of the bridge, and the cooperation of the above-mentioned structures solves the problem that the cable is bent and cannot be straightened after being taken off and laid in the interior of the bridge due to the long-time storage of the cable on the cable, and the cable is easily detached from the bridge.
