Description

Technical Field

[0001] The utility model relates to the technical field of field bridge hoist cable protection, in particular to a field bridge hoist cable fixing tool. Background Art

[0002] The crane hoist cable is responsible for transmitting electricity from the power supply to various parts of the hoist, providing power for the operation of the hoist. It also undertakes the important task of signal transmission, transmitting various control signals and feedback signals of the hoist to the control system, so as to realize precise control and monitoring of the hoist.

[0003] Through the spreader cable, the operator can control the various movements of the spreader, such as rotation, extension, opening and closing of the box, unpacking of the box, etc., so as to realize the lifting and loading and unloading of the goods. It can ensure the safety and stability of the spreader during operation and prevent the spreader from losing control or other safety accidents caused by cable failure.

[0004] A stable and reliable cable system for the crane can improve the operation efficiency of the crane and reduce downtime. The crane crane cable needs to be able to adapt to various harsh working environments, such as high temperature, low temperature, humidity, corrosion, etc., to ensure its normal operation. Our automated crane crane cable has built-in optical fiber with data transmission function, which can transmit the operation data of the crane to the monitoring system in real time for data analysis and fault diagnosis.

[0005] Due to the influence of working conditions, the cable of the field crane hoist is subjected to repeated vertical tension during the lifting and lowering of the hoist, and the hoist cable rotates when entering and leaving the cable storage, causing irregular shaking of the hoist cable.

[0006] A prominent problem currently faced is that the field crane hoist cable has a large number of cores, and some of them contain relatively fragile optical fibers. The suspended section from the rooting point to the cable frame entrance is too long, which causes excessive shaking, thus having a direct and serious impact on the service life of the hoist cable.

[0007] First of all, the large number of cores itself brings a certain degree of complexity. Many cores need to be reasonably laid out and arranged in a small space, which not only increases the difficulty of manufacturing and installation, but also makes the cable more prone to failure during operation. Once one or several cores have problems, it may trigger a chain reaction and affect the normal operation of the entire system. In addition, the cores may also reduce the quality and stability of signal transmission due to mutual interference and other reasons.

[0008] What is more critical is the optical fiber part. Optical fiber itself is highly sensitive and fragile, and needs to be protected with extra care during normal use. In the field crane hoist cable, due to the long suspended section and excessive shaking, the optical fiber is always at risk of being stretched, bent, or even damaged. In this case, the performance of the optical fiber may be greatly affected, resulting in data transmission errors or interruptions, which in turn affects the accuracy and efficiency of the entire operation process.

[0009] The problem of too long suspended section and too much shaking is like a hidden time bomb. Long-term excessive shaking will cause continuous stress and fatigue damage to the cable structure. Each shaking is a small impact on the cable. Over time, these small damages gradually accumulate and eventually lead to obvious signs of damage to the cable, such as cracked outer skin and broken core, which greatly shortens its service life.

[0010] From a practical perspective, a shorter service life means higher costs. Frequent cable replacement not only requires a large amount of money to purchase new cables, but also increases equipment downtime, affecting operating efficiency and production progress. At the same time, it also brings greater work pressure to maintenance personnel, who need to constantly perform inspections, repairs, and replacements. Utility Model Content

[0018] The first arc-shaped protection plate and the second arc-shaped protection plate are relatively buckled and connected to clamp and fix the first protection structure.

[0019] According to one aspect of the utility model, when the first arc-shaped protection plate and the second arc-shaped protection plate are buckled and connected, there is a gap between the two opposite sides of the first arc-shaped protection plate and the second arc-shaped protection plate.

In this way, the first protection structure made of soft material can be wrapped around the periphery of the cable to provide basic protection for the cable, playing a role of buffer protection. On this basis, the rigid second protection structure is arranged around the periphery of the first protection structure to fix the first protection structure, and at the same time, the internal cable is protected together with the first protection structure to ensure that the cable will not be repeatedly stretched or bent due to irregular movement caused by external force, and provide basic external shaping and limiting for the cable. On this basis, the second protection structure is fixedly supported by the fixed support structure, so that the position of the cable can be fixed by the second protection structure, ensuring that the cable will not shake due to external force, ensuring the stability of position and posture, and ensuring its service life.

[0025] According to one solution of the utility model, the first protective structure is an annular rubber wrapped around the outer periphery of the field crane hoist cable.
