Description

Technical Field

[0001] The utility model relates to the technical field of port equipment, in particular to a cable commutator with an anti-scratch function. Background Art

[0002] At present, stackers and reclaimers are equipped with reels for collecting and releasing cables. In order to better restrain the cables, such as Figure 1 As shown, a cable commutator 1 is usually installed near the center of the stacker-reclaimer track. The cable wound on the reel first passes through the inlet end 11 of the cable commutator, and then passes through the outlet end 12 of the cable commutator and is connected to the high-voltage power supply to ensure that a section of cable between the outlet end and the high-voltage power supply does not move, while the cable at the inlet end swings left and right with the movement of the stacker-reclaimer. When the stacker-reclaimer moves from the left side of the cable commutator to the right side of the cable commutator, the reel receives a signal and first reels in the cable to avoid cable accumulation. When the cable at the inlet end swings from the left to the right, the reel releases the cable to avoid cable breakage. However, due to the particularity of the material yard foundation (close to the water, the underground is mainly sandy), the tracks of the stacker-reclaimer on the material yard will sink to varying degrees after long-term use, causing the stacker-reclaimer to slip on the track or fail to brake. If the stacker-reclaimer slides from one side of the cable commutator to the other side, the reel will not receive the work instruction because the stacker-reclaimer is not moving normally, and will not reel in or release the cable. During the sliding process, the accompanying cable will first accumulate and then be straightened as the stacker-reclaimer moves. Since the left and right sides of the cable commutator are vertical surfaces, the cable at the inlet end is easily entangled and stuck on the side wall of the inlet or outlet end during commutation. Therefore, the stuck cable is subjected to huge tension when the stacker-reclaimer stops, and the side wall of the cable commutator scratches the cable like a blade, causing cable damage and affecting power safety. Utility Model Content

[0003] The utility model aims to provide a cable commutator with anti-scratch function to avoid cable damage and ensure electricity safety in view of the shortcomings of the prior art.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the cable commutator with anti-scratch function of the utility model is:

[0005] A cable commutator with an anti-scratch function comprises a cable commutator, wherein bridges are arranged on both sides of the cable commutator, the bridges comprise a first guide slide located at the edge of the top surface of the cable commutator, second guide slides extending to the outside of the cable commutator are arranged at both ends of the first guide slide, one end of the second guide slide closely adjacent to the cable commutator is smoothly connected to the first guide slide, and one end of the second guide slide away from the cable commutator is not higher than the foundation surface.

[0006] Preferably, the first guide slide is in a straight-sided shape and is arranged horizontally.

[0007] Preferably, the second guide slide is in a straight-sided shape.

[0008] Preferably, the angle between the second guide slide and the foundation surface is 0°﹤θ≤70°.

[0009] Preferably, the second guide slide is arc-shaped.

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] The cable can slide along the bridge from one end of the cable commutator to the other end, preventing the cable from being wrapped around the outside of the cable commutator when the stacker-reclaimer slips on the cable commutator, protecting the cable from being scratched and ensuring electrical safety.

[0017] The present invention is further explained below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that these implementation methods are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, various equivalent forms of modifications to the present invention by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0018] Embodiment 1, as Figure 2 , 3As shown, a cable commutator with anti-scratch function includes a cable commutator, and a bridge 2 is arranged on the front and rear sides of the cable commutator. The bridge is parallel to the track of the stacker and reclaimer. The bridge includes a first guide slide 21, the first guide slide is straight-sided and arranged horizontally, so as to facilitate welding the first guide slide to the edge of the top surface of the cable commutator. Second guide slides 22 extending to the outside of the cable commutator are arranged at both ends of the first guide slide, and the second guide slide is straight-sided. The first and second guide slides can be formed by bending the same galvanized steel pipe.

[0019] Embodiment 2, as Figure 4 As shown, a cable commutator with anti-scratch function includes a cable commutator. Bridges 2 are arranged on both sides of the cable commutator. The bridges are parallel to the tracks of the stacker and reclaimer. The bridges include a first guide slide 21. The first guide slide is straight-sided and arranged horizontally to facilitate welding the first guide slide to the edge of the top surface of the cable commutator. Second guide slides 22 extending to the outside of the cable commutator are arranged at both ends of the first guide slide. The second guide slide is arc-shaped.

[0020] The specific working process and principle of a cable commutator with anti-scratch function: if the stacker and reclaimer working on the left side of the cable commutator slips and slides along the track of the stacker and reclaimer to the right side of the cable commutator, the accompanying cable slides from the left side of the bridge to the right side, and will not contact the steel plate on one side of the outlet end of the cable commutator, thereby avoiding being scratched by the steel plate at the outlet end, thereby avoiding property loss and ensuring safe use of electricity. The utility model prevents the cable from being stuck during commutation by arranging a bridge on the existing cable commutator, and has a simple structure, significant effect, and is safe and reliable.
